‎1.【说明文阅读】【2016·全国新课标II】 C Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website BookCrossing.com turns the page on the traditional idea of a book group.‎ Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.‎ ‎ Bruce Pederson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”‎ ‎ Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.‎ ‎ People who find a book can also leave a journal entry describing what they thought of it. E-mails are then sent to the BookCrossing to keep them updated about where their books have been found. Bruce peterson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.‎ ‎ BookCrossing is part of a trend among people who want to get back to the “real” and not the virtual(虚拟). The site now has more than one million members in more than one hundred thirty-five countries.‎ ‎9. Why does the author mention book groups in the first paragraph?‎ A.

In the 1980s, electrical lines and lead poisoning(铅中毒) nearly drove them to dying out. Now, electric shock training and medical treatment are helping to rescue these big birds.‎ ‎ In the late 1980s, the last few condors were taken from the wild, and there are now more than 150 flying over California and nearby Arizona, Utah and Baja in Mexico.‎ ‎ Electrical lines have been killing them off. “As they go in to rest for the night, they just don’t see the power lines,” says Bruce Rideout of San Diego Zoo. Their wings can bridge the gap between lines, resulting in electrocution(电死) if they touch two lines at once.‎ ‎ So scientists have come up with a shocking idea. Tall poles, placed in large training areas, teach the birds to stay clear of electrical lines by giving them a painful but undeadly electric shock. Before the training was introduced, 66% of set-freed condors died of electrocution. This has now dropped to 18%.‎ ‎ Lead poisonous has proved more difficult to deal with. When condors eat dead bodies of other animals containing lead, they absorb large quantities of lead. This affects their nervous systems and ability to produce baby birds, and can lead to kidney(肾) failures and death. So condors with high levels of lead are sent to Los Angeles Zoo, where they are treated with calcium EDTA, a chemical that removes lead from the blood over several days. This work is starting to pay off. The annual death rate for adult condors has dropped from 38% in 2000 to 5.4% in 2011. ‎ ‎ Rideout’s team thinks that the California condors’ average survival time in the wild is now just under eight years. “Although these measures are not effective forever, they are vital for now,” he says. “They are truly good birds that are worth every effort we put into recovering them. ”‎ ‎63.California condors attract researchers’ interest because they .‎ ‎ A.are active at night ‎ B.had to be bred in the wild ‎ C.are found on in California ‎ D.almost died out in the 1980s ‎64. Researchers have found electrical lines are .‎ ‎ A.blocking condors’ journey home ‎ ‎ B. big killers of Califorbnia condoras ‎ C. rest places for condors at night ‎ D. used to keep condors away ‎65.

His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier.‎ ‎ These are the findings of a 40-year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. “Boys who worked in the home or community gained competence (能力) and came to feel they were worthwhile members of society,” said George Vaillant, the psychologist ‎ ‎(心理学家) who made the discovery. “And because they felt good about themselves, others felt good about them.”‎ ‎ Vaillant’s study followed these males in great detail. Interviews were repeated at ages 25, 31 and 47. Under Vaillant, the researchers compared the men’s mental-health scores with their boyhood-activity scores with their boyhood-activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.‎ ‎ The link between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out. Working----at any age----is important. Childhood activities help a child develop responsibility, independence, confidence and competence---the underpinnings (基础) of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this. Yet work isn’t everything. As Tolstoy once said, “One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one’s work.”‎ ‎46. What do we know about John?‎ A. He enjoyed his career and marriage.‎ B. He had few childhood playmates.‎ C. He received little love from his family.‎ D. He was envied by others in his childhood.‎ ‎47. Vaillant’s words in Paragraph 2 serve as _____.‎ A. a description of personal values and social values B. an analysis of how work was related to competence C. an example for parents’ expectations of their children D. an explanation why some boys grew into happy men ‎48. Vaillant’s team obtained their findings by _____.‎ A. recording the boys’ effort in school B. evaluating the men’s mental health C. comparing different sets of scores D. measuring the men’s problem solving ability ‎49. What does the underlined word “sharp” probably mean in Paragraph 4?‎ A. Quick to react B. Having a thin edge C. Clear and definite D. sudden and rapid ‎50. What can be inferred from the last paragraph?‎ A. competent adults know more about love than work.‎ B. Emotional health is essential to a wonderful adult life.‎ C. Love brings more joy to people than work does.‎ D. Independence is the key to one’s success.‎ ‎ ‎ ‎【答案】46.A 47.D 48.C 49.C 50.B ‎4.【说明类短文阅读】【2016·浙江】 C A scientist working at her lab bench and a six-old baby playing with his food might seem to ‎ have little in common.After all,the scientist is engaged in serious research to uncover the very nature of the physical world,and the baby is,well, just playing…right?Perhaps,but some developmental psychologists have argued that this “play” is more like a scientific investigation than one might think.‎ Take a closer look at the baby playing at the table. Each time the bowl of rice is pushed over the table edge, it falls in the ground---and, in the process, it belongs out important evidence about how physical objects interact ; bowls of rice do not flood in mid-sit, but require support to remain stable. It is likely that babies are not born knowing the basic fact of the universe; nor are they ever clearly taught it. Instead, babies may form an understanding of object support through repeated experiments and then build on this knowledge to learn even more about how objects interact. Though their ranges and tools differ, the baby’s investigation and the scientist’s experiment appear to share the same aim(to learn about the natural world ), overall approach (gathering direct evidence from the world), and logic (are my observations what I expected?).‎ Some psychologists suggest that young children learn about more than just the physical world in this way---that they investigate human psychology and the rules of language using similar means. For example, it may only be through repeated experiments, evidence gathering, and finally overturning a theory, that a baby will come to accept the idea that other people can have different views and desires from what he or she has. for example, unlike the child , Mommy actually doesn’t like Dove chocolate.‎ ‎ Viewing childhood development as a scientific investigation throws on how children learn ,but it also offers an inspiring look at science and scientists. Why do young children and scientists seem to be so much alike? Psychologists have suggested that science as an effort ---the desire to explore, explain, and understand our world---is simply something that comes from our babyhood. Perhaps evolution provided human babies with curiosity and a natural drive to explain their worlds, and adult scientists simply make use of the same drive that served them as children. The same cognitive systems that make young children feel good about feel good about figuring something out may have been adopted by adult scientists. As some psychologists put it, ”It is ‎ not that children are little scientists but that scientists are big children.”‎ ‎50. According to some developmental psychologists, ‎ A. a baby’s play is nothing more than a game.‎ B. scientific research into babies; games is possible C. the nature of babies’ play has been thoroughly investigated D. a baby’s play is somehow similar to a scientist’s experiment ‎51.We learn from Paragraph 2 that ‎ A. scientists and babies seem to observe the world differently B. scientists and babies often interact with each other C. babies are born with the knowledge of object support D. babies seem to collect evidence just as scientists do ‎52. Children may learn the rules of language by ‎ A. exploring the physical world B. investigating human psychology C. repeating their own experiments D. observing their parents’ behaviors ‎53. What is themain idea of the last paragraph?‎ A. The world may be more clearly explained through children’s play.‎ B. Studying babies’ play may lead to a better understanding of science.‎ C. Children may have greater ability to figure out things than scientists.‎ D. One’s drive for scientific research may become stronger as he grows.‎ ‎54. What is the author’s tone when he discusses the connection between scientists’ research and babies’ play?‎ ‎ A. Convincing. B. Confused. C. Confidence. D. Cautious.‎ ‎ ‎ ‎【答案】50. D 51. D 52.C 53.

But beyond the minimum requirements as social beings, they have little instinct (本能) to help one another. Chimps in the wild seek food for themselves. Even chimp mothers regularly decline to share food with their children. Who are able from a young age to gather their own food.‎ ‎ In the laboratory, chimps don’t naturally share food either. If a chimp is put in a cage where he can pull in one plate of food for himself or, with no great effort, a plate that also provides food for a neighbor to the next cage, he will pull at random ---he just doesn’t care whether his neighbor gets fed or not. Chimps are truly selfish.‎ Human children, on the other hand are extremely corporative. From the earliest ages, they decide to help others, to share information and to participate a achieving common goals. The psychologist Michael Tomasello has studied this cooperativeness in a series of expensive with very young children. He finds that if babies aged 18 months see an worried adult with hands full trying to open a door, almost all will immediately try to help.‎ There are several reasons to believe that the urges to help, inform and share are not taught .but naturally possessed in young children. One is that these instincts appear at a very young age before most parents have started to train children to behave socially. Another is that the helping behaviors are not improved if the children are rewarded. A third reason is that social intelligence. Develops in children before their general cognitive（认知的）skills,at least when compared with chimps..In tests conducted by Tomtasell, the children did no better than the chimps on the physical world tests, but were considerably better at understanding the social world The cure of what children’s minds have and chimps’ don’t in what Tomasello calls what. Part of this ability is that they can infer what others know or are thinking. But that, even very young children want to be part of a shared purpose. They actively seek to be part of a “we”, a group that intends to work toward a shared goal.‎ ‎58. What can we learn from the experiment with chimps?‎ ‎ A. Chimps seldom care about others’ interests.‎ B. Chimps tend to provide food for their children.‎ C. Chimps like to take in their neighbors’ food.‎ D. Chimps naturally share food with each other.‎ ‎59. Michael Tomasello’s tests on young children indicate that they____.‎ ‎ A. have the instinct to help others B. know how to offer help to adults C. know the world better than chimps D. trust adults with their hands full ‎60. The passage is mainly about ____.‎ ‎ A. the helping behaviors of young children B. ways to train children’s shared intentionality C. cooperation as a distinctive human nature D. the development of intelligence in children ‎ ‎ ‎【答案】58.A 59.A 60.C ‎ ‎6.【科普说明文阅读】【2016·江苏】 C El Nifio, a Spanish term for “the Christ child”, was named by South American fisherman who noticed that the global weather pattern, which happens every two to seven years, reduced the amount of fishes caught around Christmas. El Nifio sees warm water, collected over several years in the western Pacific, flow back eastwards when winds that normally blow westwards weaken, or sometimes the other way round.‎ The weather effects both good and bad, are felt in many places. Rich countries gain more from powerful Nifio, on balance, than they lose. A study found that a strong Nifio in 1997 helped American’s economy grow by 15 billion, partly because of better agricultural harvest, farmers in the Midwest gained from extra rain. The total rise in agricultural in rich countries in growth than the fall in poor ones.‎ But in Indonesia extremely dry forests are in flames. A multi-year drought (干旱）in south-east Brazil is becoming worse. Though heavy rains brought about by El Nino may relieve the drought in California, they are likely to cause surface flooding and other disasters.‎ The most recent powerful Nino, in 1997-98, killed around 21,000 people and caused damage worth $36 billion around the globe. But such Ninos come with months of warning, and so much is known about how they happen that governments can prepare. According to the Overseas Development Institute (ODI), however, just 12% of disaster-relief funding in the past two decades has gone on reducing risks in advance, rather than recovery and rebuilding afterwards. This is despite evidence that a dollar spent on risk-reduction saves at least two on reconstruction.‎ Simple improvements to infrastructure (基础设施）can reduce the spread of disease. Better sewers (下水道）make it less likely that heavy rain is followed by an outbreak of the disease of bad stomach. Stronger bridges mean villages are less likely to be left without food and medicine after floods. According to a paper in 2011 by Mr Hsiang and co-authors, civil conflict is related to El Nino’s harmful effects—and the poorer the country, the stronger the link. Though the relationship may not be causal, helping divided communities to prepare for disasters would at least reduce the risk that those disasters are followed by killing and wounding people. Since the poorest are least likely to make up for their losses from disasters linked to El Nino, reducing their losses needs to be the priority.‎ ‎61. What can we learn about El Nino in Paragraph 1?‎ A. It is named after a South American fisherman.‎ B. It takes place almost every year all over the world.‎ C. It forces fishermen to stop catching fish around Christmas.‎ D. It sees the changes of water flow direction in the ocean.‎ ‎62. What may El Ninos bring about to the countries affected?‎ A. Agricultural harvests in rich countries fall.‎ B. Droughts become more harmful than floods.‎ C. Rich countries’ gains are greater than their losses.‎ D. Poor countries suffer less from droughts economically.‎ ‎63. The data provided by ODI in Paragraph 4 suggest that_________.‎ A. more investment should go to risk reduction B. governments of poor countries need more aid C. victims of El Nino deserve more compensation D. recovery and reconstruction should come first ‎64. What is the author’s purpose in writing the passage?‎ A. To introduce El Nino and its origin.‎ B. To explain the consequences of El Nino.‎ C. To show ways of fighting against El Nino.‎ D.

Here are some examples.‎ First consider something as simple as sleep. Its position presents its own challenges. The main question is whether you want your arms inside or outside the sleeping bag. If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled （芭蕾）dancer. “I’m an inside guy,” Mike Hopkins says, who returned from a six-month tour on the International Space Station. “I like to be wrapped up.”‎ On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it’s just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale (呼气) has a tendency to form an invisible （隐形的）cloud around you head. You can end up with what astronauts call a carbon-dioxide headache.‎ Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before you float out of your seat,”Your inner ear thinks you’re falling . Meanwhile your eyes are telling you you’re standing straight. That can be annoying—that’s why some people feel sick.” Within a couple days —truly terrible days for some —astronauts’ brains learn to ignore the panicky signals from the inner ear, and space sickness disappears.‎ Space travel can be so delightful but at the same time invisibly dangerous. For instance, astronauts lose bone mass. That’s why exercise is considered so vital that National Aeronautics and Space Administration (NASA) puts it right on the workday schedule. The focus on fitness is as much about science and the future as it is about keeping any individual astronauts return home, and, more importantly, how to maintain strength and fitness for the two and a half years or more that it would take to make a round-trip to Mars.‎ ‎63.What is the major challenge to astronauts when they sleep in space?‎ A. Deciding on a proper sleep position B. Choosing a comfortable sleeping bag C. Seeking a way to fall asleep quickly D. Finding a right time to go to sleep.‎ ‎64.The astronauts will suffer from a carbon-dioxide headache when _____.‎ ‎ A. the y circle around on their bikes B. they use microcomputers without a stop C. they exercise in one place for a long time D. they watch a movie while pedaling ‎65.Some astronauts feel sick on the station during the first few days because _____.‎ A. their senses stop working B. they have to stand up straight C. they float out of their seats unexpectedly D. whether they are able to go back to the station ‎66.One of the NASA’s major concerns about astronauts is _____.‎ A. how much exercise they do on the station B. how they can remain healthy for long in space C. whether they can recover after returning home D. whether they are able to go back to the station ‎ ‎ ‎【答案】63.A 64.

These animals typically live between the surface of the ocean and a depth of about 3,300 feet—as far as most light can reach. Most of them are extremely delicate and can be damaged by a simple touch. Sonke Johnsen, a scientist in biology, says, “These animals live through their life alone. They never touch anything unless they’re eating it, or unless something is eating them.”‎ ‎ And they are as clear as glass. How does an animal become see-through? It’s trickier than you might think.‎ ‎ The objects around you are visible because they interact with light. Light typically travels in a straight line. But some materials slow and scatter(散射) light, bouncing it away from its original path. Others absorb light, stopping it dead in its tracks. Both scattering and absorption make an object look different from other objects around it, so you can see it easily.‎ ‎ But a transparent object doesn’t absorb or scatter light, at least not very much, Light can pass through it without bending or stopping. That means a transparent object doesn’t look very different from the surrounding air or water. You don’t see it ----you see the things behind it.‎ ‎ To become transparent, an animal needs to keep its body from absorbing or scattering light. Living materials can stop light because they contain pigments(色素) that absorb specific colors of light. But a transparent animal doesn’t have pigments, so its tissues won’t absorb light. According to Johnsen, avoiding absorption is actually easy. The real challenge is preventing light from scattering.‎ Animals are built of many different materials----skin, fat, and more----and light moves through each at a different speed. Every time light moves into a material with a new speed, it bends and scatters. Transparent animals use different tricks to fight scattering. Some animals are simply very small or extremely flat. Without much tissue to scatter light, it is easier to be see—through. Others build a large, clear mass of non-living jelly-lie(果冻状的)material and spread ‎ themselves over it .‎ ‎ Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light exactly as much as water does. They need to look uniform. But how they’re doing it is still unknown. One thing is clear for these larger animals, staying transparent is an active process. When they die, they turn a non-transparent milky white.‎ ‎63. According to Paragraph 1, transparent animals_______.‎ ‎ A. stay in groups B. can be easily damaged ‎ C. appear only in deep ocean D. are beautiful creatures ‎64. The underlined word “dead” in Paragraph 3 means__________.‎ ‎ A. silently B. gradually ‎ C. regularly D. completely ‎65. One way for an animal to become transparent is to ________.‎ ‎ A. change the direction of light travel ‎ ‎ B. gather materials to scatter light.‎ ‎ C. avoid the absorption of light ‎ D. grow bigger to stop light.‎ ‎66. The last paragraph tells us that larger transparent animals________.‎ ‎ A. move more slowly in deep water ‎ B. stay see-through even after death ‎ C. produce more tissues for their survival ‎ D. take effective action to reduce light spreading ‎ ‎ ‎【答案】63.B 64.D 65.C 66.D ‎9.【科普说明文阅读】【2015·江苏】 B In the United States alone, over 100 million cell-phones are thrown away each year. Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants. The electronic waste stream is increasing three times faster than traditional garbage as a whole.‎ Electronic devices contain valuable metals such as gold and silver. A Swiss study reported that while the weight of electronic goods represented by precious metals was relatively small in comparison to total waste, the concentration (含量) of gold and other precious metals was higher in So-called e-waste than in naturally occurring minerals.‎ Electronic wastes also contain many poisonous metals. Even when the machines are recycled and the harmful metals removed, the recycling process often is carried out in poor countries, in practically uncontrolled ways which allow many poisonous substances to escape into the environment.‎ Creating products out of raw materials creates much more waste material, up to 100 times more, than the material contained in the finished products. Consider again the cell-phone, and imagine the mines that produced those metals, the factories needed to make the box and packaging(包装) it came in. Many wastes produced in the producing process are harmful as well.‎ The U.S. Environmental Protection Agency notes that most waste is dangerous in that “the production, distribution, and use of products — as well as management of the resulting waste — all result in greenhouse gas release.” Individuals can reduce their contribution by creating less waste at the start — for instance, buying reusable products and recycling.‎ In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive (动机) for reducing waste. If producers are required to take back packaging they use to sell their products, would they reduce the packaging in the first place?‎ Governments’ incentive to require producers to take responsibility for the packaging they produce is usually based on money. Why, they ask, should cities or towns be responsible for paying to deal with the bubble wrap (气泡垫) that encased your television?‎ From the governments’ point of view, a primary goal of laws requiring extended producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers.‎ ‎58.By mentioning the Swiss study, the author intends to tell us that _________ .‎ A. the weight of e-goods is rather small B. E-waste deserves to be made good use of C. natural minerals contain more precious metals D. the percentage of precious metals is heavy in e-waste ‎59.The responsibility of e-waste treatment should be extended _________ .‎ A. from producers to governments ‎ B. from governments to producers C. from individuals to distributors ‎ D. from distributors to governments ‎60. What does the passage mainly talk about?‎ A. The increase in e-waste. ‎ B. The creation of e-waste.‎ C. The seriousness of e-waste. ‎ D. The management of e-waste.‎ ‎ ‎ ‎【答案】58.B 59.B 60.D ‎10.【社会文化类阅读】【2015·江苏】 C Suppose you become a leader in an organization. It’s very likely that you’ll want to have volunteers to help with the organization’s activities. To do so, it should help to understand why people undertake volunteer work and what keeps their interest in the work.‎ Let’s begin with the question of why people volunteer. Researchers have identified several factors that motivate people to get involved. For example, people volunteer to express personal values related to unselfishness, to expand their range of experiences, and to strengthen social relationships. If volunteer positions do not meet these needs, people may not wish to participate. To select volunteers, you may need to understand the motivations of the people you wish to attract.‎ People also volunteer because they are required to do so. To increase levels of community service, some schools have launched compulsory volunteer programs. Unfortunately, these programs can shift people’s wish of participation from an internal factor (e.g., “I volunteer because it’s important to me”) to an external factor (e.g., “I volunteer because I’m required to do so”). When that happens, people become less likely to volunteer in the future. People must be sensitive to this possibility when they make volunteer activities a must.‎ Once people begin to volunteer, what leads them to remain in their positions over time? To answer this question, researchers have conducted follow-up studies in which they track volunteers over time. For instance, one study followed 238 volunteers in Florida over a year. One of the most important factors that influenced their satisfaction as volunteers was the amount of suffering they experienced in their volunteer positions. Although this result may not surprise you, it leads to important practical advice. The researchers note that attention should be given to “training methods that would prepare volunteers for troublesome situations or provide them with strategies for coping with the problem they do experience”.‎ Another study of 302 volunteers at hospitals in Chicago focused on individual differences in the degree to which people view “volunteer” as an important social role. It was assumed that those people for whom the role of volunteer was most part of their personal identity would also ‎ be most likely to continue volunteer work. Participants indicated the degree to which the social role mattered by responding to statements such as “Volunteering in Hospital is an important part of who I am.” Consistent with the researchers’ expectations, they found a positive correlation (正相关) between the strength of role identity and the length of time people continued to volunteer. These results, once again, lead to concrete advice: “Once an individual begins volunteering, continued efforts might focus on developing a volunteer role identity.... Items like T-shirts that allow volunteers to be recognized publicly for their contributions can help strengthen role identity”.‎ ‎61.People volunteer mainly out of ______ .‎ A. academic requirements B. social expectations C. financial rewards D. internal needs ‎62.What can we learn from the Florida study?‎ A. Follow-up studies should last for one year. B. Volunteers should get mentally prepared.‎ C. Strategy training is a must in research. D. Volunteers are provided with concrete advice.‎ ‎63.What is most likely to motivate volunteers to continue their work?‎ A. Individual differences in role identity. B. Publicly identifiable volunteer T-shirts.‎ C. Role identity as a volunteer. D. Practical advice from researchers.‎ ‎64.What is the best title of the passage?‎ A. How to Get People to Volunteer B. How to Study Volunteer Behaviors C. How to Keep Volunteers’ Interest D. How to Organize Volunteer Activities ‎ ‎ ‎【答案】61.D 62.B 63.C 64.A ‎11.【教育类短文阅读】【2015·广东】 C Daniel Anderson, a famous psychologist, believes it’s important to distinguish television’s influences on children from those of the family. We tend to blame TV, he says, for problems it doesn’t really cause, overlooking our own roles in shaping children’s minds.‎ One traditional belief about television is that it reduces a child’s ability to think and to understand the world. While watching TV, children do not merely absorb words and images (影像). Instead, they learn both explicit and hidden meanings from what they see. Actually, children learn early the psychology of characters in TV shows. Furthermore, as many teachers agree, children understand far more when parents watch TV with them, explaining new words and ideas. Yet, most parents use an educational program as a chance to park their kids in front of the set and do something in another room.‎ Another argument against television is that it replaces reading as a form of entertainment. But according to Anderson, the amount of time spent watching television is not related to reading ability. TV doesn’t take the place of reading for most children; it takes the place of similar sorts of recreation, such as listening to the radio and playing sports. Things like parents’ educational background have a stronger influence on a child’s reading. “A child’s reading ability is best predicted by how much a parent reads.” Anderson says.‎ Traditional wisdom also has it that heavy television-watching lowers IQ (智商) scores and affects school performance. But here, too, Anderson notes that no studies have proved it. In fact, research suggests that it’s the other way around. “If you’re smart young, you’ll watch less TV when you’re older,” Anderson says. Yet, people of lower IQ tend to be lifelong television viewers.‎ For years researchers have attempted to show that television is dangerous to children.

The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of, certain animals and birds, and even disturbs the world’s ecological balance.‎ On a local level, the damage of the forest required by full-sun fields affects the area’s birds and animals. The shade of the forest trees provides a home for birds and other special(物种) that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.‎ On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威胁)human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world's groundwater.‎ Both locally and globally, the continued spread of full-sun coffee plantations (种植园)could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate, and studies show that loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic(酸性的) soil conditions.‎ It is obvious that the way much coffee is grown affects many aspects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.‎ ‎54. What can we learn about full-sun coffee production from Paragraph 4?‎ A. It limits the spread of new growing techniques.‎ B. It leads to air pollution and global warming.‎ C. It slows down the loss of shade trees.‎ D. It improves local soil conditions.‎ ‎55.

But robins are in danger of wearing themselves out by singing too much. Robins are singing all night一as well as during the day, British-based researchers say.‎ ‎ David Dominoni, of Glasgow University, said that light from street lamps, takeaway signs and homes is affecting the birds' biological clocks, leading to them being wide awake when they should be asleep.‎ ‎ Dr Dominoni, who is putting cameras inside nesting boxes to track sleeping patterns, said lack of sleep could put the birds’ health at risk. His study shows that when robins are exposed to light at night in the lab, it leads to some genes being active at the wrong time of day. And the more birds are exposed to light, the more active they are at night.‎ He told people at a conference, "There have been a couple of studies suggesting they are increasing their song output at night and during the day they are still singing. Singing is a costly behaviour and it takes energy. So by increasing their song output, there might be some costs of energy."‎ And it is not just robins that are being kept awake by artificial light. Blackbirds and seagulls are also being more nocturnal. Dr Dominoni said, "In Glasgow where I live, gulls are a serious problem. I have people coming to me saying `You are the bird expert. Can you help us kill these gulls?'.During the breeding(繁殖)season, between April and June, they are very active at night and very noisy and people can't sleep."‎ Although Dr Dominoni has only studied light pollution, other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise.‎ However, some birds thrive(兴旺)in noisy environments. A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery. It is thought that they are capitalising on their predators(天敌)fleeing to quieter areas.‎ ‎42.According to Dr Dominoni's study, what cause robins to sing so much?‎ ‎ A. The breeding season. B. The light in modern life ‎ C. The dangerous environment. D. The noise from heavy machinery.‎ ‎43.What is the researchers' concern over the increase of birds' song output?‎ ‎ A.

But a new study suggests they used a little rock‘n’roll. Long-ago builders could have attached wooden pole s to the stones and rolled then across the sand, the scientists say.‎ ‎“Technically, I think what they’re proposing is possible,” physicist Daniel Bonn said.‎ People have long puzzled over how the Egyptians moved such huge rocks. And there’s no obvious answer. On average, each of the two million big stones weighed about as much as a large pickup truck. The Egyptians somehow moved the stone blocks to the pyramid site from about one kilometer away.‎ The most popular view is that Egyptian workers slid the blocks along smooth paths. Many scientists suspect workers first would have put the blocks on sleds(滑板). Then they would have dragged them along paths. To make the work easier, workers may have lubricated the paths either with wet clay or with the fat from cattle. Bonn has now tested this idea by building small sleds and dragging heavy objects over sand.‎ Evidence from the sand supports this idea. Researchers found small amounts of fat, as well as a large amount of stone and the remains of paths.‎ However, physicist Joseph West thinks there might have been a simpler way , who led the new study . West said , “I was inspired while watching a television program showing how sleds might have helped with pyramid construction . I thought , ‘Why don’t they just try rolling the things?’ “A square could be turned into a rough sort of wheel by attaching wooden poles to its ‎ sides , he realized . That , he notes , should make a block of stone” a lot easier to roll than a square”.‎ So he tried it.‎ He and his students tied some poles to each of four sides of a 30-kilogram stone block. That action turned the block into somewhat a wheel. Then they placed the block on the ground.‎ They wrapped one end of a rope around the block and pulled. The researchers found they could easily roll the block along different kinds of paths. They calculated that rolling the block required about as much force as moving it along a slippery(滑的)path.‎ West hasn’t tested his idea on larger blocks, but he thinks rolling has clear advantages over sliding. At least, workers wouldn’t have needed to carry cattle fat or water to smooth the paths.‎ ‎46.It’s widely believed that the stone blocks were moved to the pyramid site by ______.‎ A. rolling them on roads B. pushing them over the sand C. sliding them on smooth paths D. dragging them on some poles ‎47.The underlined part “lubricated the paths” in Paragraph 4 means____.‎ A. made the path wet B. made the path hard C. made the path wide D. made the path slippery ‎48.What does the underlined word “it”in Paragraph 7 refer to?‎ A. Rolling the blocks with poles attached.‎ B. Rolling the blocks on wooden wheels.‎ C. Rolling poles to move the blocks.‎ D.

Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo. ‎ While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.‎ The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn’t just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.‎ Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.‎ Fellow Robots is one company bringing social robots to the market. The company’s “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product’s location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.‎ The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.‎ ‎41. How are social robots different from household robots?‎ ‎ A. They can control their emotions. B. They are more like humans.‎ C. They do the normal housework. D. They respond to users more slowly.‎ ‎42. What can a Jibo robot do according to Paragraph 3?‎ ‎ A. Communicate with you and perform operations.‎ ‎ B. Answer your questions and make requests.‎ ‎ C.

Instead，we are diurnal creatures, with eyes adapted to living in the sun’s light. This is a basic evolutionary fact, even though most of us don’t think of ourselves as diurnal beings. Yet it’s the only way to explain what we’ve done to the night: We’ve engineered it to receive us by filling it with light. ‎ The benefits of this kind of engineering come with consequences 一 called light pollution 一 whose effects scientists are only now beginning to study. Light pollution is largely the result of bad lighting design，which allows artificial light to shine outward and upward into the sky. III-designed lighting washes out the darkness of night and completely changes the light levels ‎ 一 and light rhythms — to which many forms of life, including, ourselves, have adapted. Wherever human light spills into the natural world, some aspect or life is affected . ‎ In most cities the sky looks as though it has been emptied of stars, leaving behind a vacant haze(霾) that mirrors our fear of the dark. We’ve grown so used to this orange haze that the original glory of an unlit nigh, - dark enough for the planet Venus to throw shadow on Earth, is wholly beyond our experience, beyond memory almost.‎ We’ve lit up the night as if it were an unoccupied country, when nothing could be further form the truth. Among mammals alone, the number of nocturnal species is astonishing, Light is a powerful biological force, and on many species it acts as a magnet(磁铁). The effect is so powerful that scientists speak of songbirds and seabirds being “captured” by searchlights on land or by the light from gas flares on marine oil platforms. Migrating at night, birds tend to collide with brightly lit tall buildings.‎ Frogs living near brightly lit highways suffer nocturnal light levels that are as much as a million times righter than normal, throwing nearly every aspect of their behavior out of joint including most other creatures ,we do need darkness .Darkness is as essential to our biological welfare, to our internal clockwork, as light itself.‎ Living in a glare of our making,we have cut ourselves off from our evolutionary and cultural heritage—the light of the stars and the rhythms of day and night .In a very real sense light pollution causes us to lose sight of our true place in the universe, to forget the scale of our being, which is best measured against the dimensions of a deep night with the Milky Way—the edge of our galaxy arching overhead.‎ ‎50.

If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.‎ ‎ In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research ‎ team wanted to know the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.‎ ‎ In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in a specific computer folder (文件夹). Surprisingly, people later remember the folder location (位置) better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called "transactive memory (交互记忆)".‎ ‎ According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn't mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.‎ ‎64.

An old joke that was popular at the time went something like this: A man is stuck up to his waist in a muddy Chicago street. Asked if he needs help, he replies, "No, thanks. I've got a good horse under me."‎ The city planner decided to build an underground drainage (排水) system, but there simply wasn't enough difference between the height of the ground level and the water level. The only two options were to lower the Chicago River or raise the city.‎ An engineer named Ellis Chesbrough convinced me the city that it had no choice but to build the pipes above ground and then cover them with dirt. This raised the level of the city's streets by as much as 12 feet.‎ This of course created a new problem: dirt practically buried the first floors of every building in Chicago. Building owners were faced with a choice: either change the first floors of their buildings into basements, and the second stories into main floors, or hoist the entire buildings to meet the new street level. Small wood-frame buildings could be lifted fairly easily. But what about large, heavy structures like Tremont Hotel, which was a six-story brick building?‎ That's where George Pullman came in. He had developed some house-moving skills successfully.‎ ‎ To lift a big structure like the Tremont Hotel, Pullman would place thousands of jackscrews (螺旋千斤顶) beneath the building's foundation. One man was assigned to operate each section of roughly 10 jackscrews. At Pullman's signal each man turned his jackscrew the same amount at the same time, thereby raising the building slowly and evenly. Astonishingly, the Tremont Hotel stay open during the entire operation, and many of its guests didn't even notice anything was happening. Some people like to say that every problem has a solution. But in Chicago's early history, every engineering solution seemed to create a new problem. Now that Chicago's waste water was draining efficiently into the Chicago River, the city's next step was to clean the polluted river.‎ ‎61.The author mentions the joke to show ______.‎ ‎ A. horses were fairly useful in Chicago ‎ B.

Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. you can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.‎ Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious(难为情) when they’re in poorly lit places – and so more likely to eat lots of food. If your home doesn’t have enough window light, get more lamps and flood the place with brightness.‎ Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us less hungry. So when it’s time to repaint, go blue.‎ Don’t forget the clock – or the radio. People who eat slowly tend to consume about 70 fewer ‎ calories(卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at 30 minutes. And while you’re at it, actually sit down to eat. If you need some help slowing down, turning on relaxing music. It makes you less likely to rush through a meal.‎ Downsize the dishes. Big serving bowls and plants can easily makes us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake(摄入) jumps by 14 percent. And we’ll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.‎ ‎25.

This evening, as on every Thursday night, psychologist Maud Lehanne is leading two of France’s favorite pastimes, coffee drinking and the “talking cure”. Here they are learning to get in touch with their true feelings. It isn’t always easy. They customers - some thirty Parisians who pay just under $2 (plus drinks) per session - care quick to intellectualize (高谈阔论)，slow to open up and connect. “You are forbidden to say ‘one feels,’ or ‘people think’,” Lehane told them. “Say ‘I think,’ ‘Think me’.”‎ A café society where no intellectualizing is allowed? It couldn’t seem more un-French. But Lehanne’s psychology café is about more than knowing oneself: It’s trying to help the city’s troubled neighborhood cafes. Over the years, Parisian cafes have fallen victim to changes in the French lifestyle - longer working hours, a fast food boom and a younger generation’s desire to spend more time at home. Dozens of new theme cafes appear to change the situation. Cafes focused around psychology, history, and engineering are catching on, filling tables well into the evening.‎ ‎ The city’s psychology cafes, which offer great comfort, are among the most popular places. Middle-aged homemakers, retirees, and the unemployed come to such cafes to talk about love, anger, and dreams with a psychologist. And they come to Lehanne’s group just to learn to say what they feel. “There’s a strong need in Paris for communication,” says Maurice Frisch, a cafe La Chope regular who works as a religious instructor in a nearby church. “People have few real friends. And they need to open up.” Lehanne says she’d like to see psychology cafes all over France. “If people had normal lives, these cafes wouldn’t exist”, she says, “If life weren’t a battle, people wouldn’t need a special place just to speak.” But them, it wouldn’t be France.‎ ‎32.

The real problem relates to the possibility that artificial intelligence(AI) may become extremely good at achieving something other than what we really want. In 1960 a wellknown mathematician Norbert Wiener, who founded the field of cybernetics(控制论), put it this way: “If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere(干预), we had better be quite sure that the purpose put into the machine is the purpose which we really desire.”‎ A machine with a specific purpose has another quality, one that we usually associate with living things: a wish to preserve its own existence. For the machine, this quality is not inborn, nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task. If we are not careful, then, we could face a kind of global chess match against very determined, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard. ‎ The possibility of entering into and losing such a match should concentrate the minds of computer scientists. Some researchers argue that we can seal the machines inside a kind of firewall, using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that plan seems unlikely to work: we have yet to invent a firewall that is secure against ordinary humans, let alone super intelligent machines.‎ Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which to plan for the arrival of super intelligent machines. But the problem should not be dismissed out of hand, as it has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teams—yet that is not possible unless machines share the goals of humans. Others say we can just “switch them off” as if super intelligent machines are too stupid to think of that possibility. Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, “Anyone who expects a source of power in the transformation of these atoms is ‎ talking moonshine.” However, on September 12, 1933, physicist Leo Szilard invented the neutroninduced(中子诱导) nuclear chain reaction.‎ ‎67．Paragraph 1 mainly tells us that artificial intelligence may ________．‎ A．run out of human control B．satisfy human's real desires C．command armies of killer robots D．work faster than a mathematician ‎68．Machines with specific purposes are associated with living things partly because they might be able to ________．‎ A．prevent themselves from being destroyed B．achieve their original goals independently C．do anything successfully with given orders D．beat humans in international chess matches ‎69．According to some researchers, we can use firewalls to ________．‎ A．help super intelligent machines work better B．be secure against evil human beings C．keep machines from being harmed D．avoid robots' affecting the world ‎70．What does the author think of the safety problem of super intelligent machines?‎ A．It will disappear with the development of AI.‎ B．It will get worse with human interference.‎ C．It will be solved but with difficulty.‎ D．It will stay for a decade.‎ ‎【文章大意】 本文为科普类文章，讲的是随着科技的发展，人工智能 (AI)可能会超出人类的控制。‎ ‎67．A　段落大意题。第一段第二句说“人工智能虽然擅长完成任务，但这有可能不是我们真正想要的”。因此选A。‎ ‎2.【科普说明文阅读】【2017·江苏卷】‎ B Before birth，babies can tell the difference between loud sounds and voices. They can even distinguish their mother's voice from that of a female stranger. But when it comes to embryonic learning (胎教)，birds could rule the roost. As recently reported in The Auk：Ornithological Advances，some mother birds may teach their young to sing even before they hatch (孵化). Newborn chicks can then imitate their mum's call within a few days of entering the world.‎ This educational method was first observed in 2012 by Sonia Kleindorfer，a biologist at Flinders University in South Australia，and her colleagues. Female Australian superb fairy wrens were found to repeat one sound over and over again while hatching their eggs. When the eggs were hatched，the baby birds made the similar chirp to their mothers—a sound that served as their regular “feed me！” call.‎ To find out if the special quality was more widespread in birds，the researchers sought the redbacked fairy wren，another species of Australian songbird. First they collected sound data from 67 nests in four sites in Queensland before and after hatching. Then they identified begging calls by analysing the order and number of notes. A computer analysis blindly compared calls produced by mothers and chicks，ranking them by similarity.‎ It turns out that baby redbacked fairy wrens also emerge chirping like their mums. And the more frequently mothers had called to their eggs，the more similar were the babies' begging calls. In addition，the team set up a separate experiment that suggested that the baby birds that most closely imitated their mum's voice were rewarded with the most food.‎ This observation hints that effective embryonic learning could signal neurological (神经系统的) strengths of children to parents. An evolutionary inference can then be drawn. “As a parent，do you invest in quality children，or do you invest in children that are in need？”Kleindorfer asks. “Our results suggest that they might be going for quality.”‎ ‎58．The underlined phrase in Paragraph 1 means “________”．‎ A．be the worst B．be the best C．be just as bad D．be just as good ‎59．What are Kleindorfer's findings based on?‎ A．Similarities between the calls of mums and chicks.‎ B．The observation of fairy wrens across Australia.‎ C．The data collected from Queensland's locals.‎ D．Controlled experiments on wrens and other birds.‎ ‎60．Embryonic learning helps mother birds to identify the baby birds which ________．‎ A．can receive quality signals ‎ B．are in need of training C．fit the environment better ‎ D．make the loudest call ‎【文章大意】 本文是一篇科普说明文。文章介绍了一项新发现：幼鸟在被孵化前母鸟便教它们识别声音了。母亲呼唤它们的鸟蛋越频繁，则它们的孩子越会发出相似的声音；幼鸟的声音越像它们母亲的声音，则它们获得的食物奖励就越多。‎ ‎58. B　词义猜测题。第一段将人类婴儿与幼鸟进行了对比，画线词组所在句上文讲出生前人的辨别声音的能力很强，下文讲一些母鸟在幼鸟被孵化之前就教它们学唱歌了。据此可以判断，在胎教方面，鸟儿的表现是最好的，推测“rule the roost”意为“be the best”，故选B项。‎ ‎59. A　细节理解题。根据第二段第三句“When the eggs were hatched, the baby birds made the similar chirp to their mothers—a sound that served as their regular ‘feed me！’ call.”可知，当这些幼鸟被孵化出来的时候，它们也发出了和它们的妈妈类似的鸣叫。据此可知，Sonia Kleindorfer的发现是以母鸟和幼鸟叫声的相似点为基础的，故选A项。‎ ‎3.【环保类短文阅读】【2017·江苏卷】‎ D Old problem，new approaches While clean energy is increasingly used in our daily life，global warming will continue for some decades after CO2 emissions (排放) peak. So even if emissions were to begin to decrease today，we would still face the challenge of adapting to climate change. Here I will stress some smarter and more creative examples of climate adaptation.‎ When it comes to adaptation，it is important to understand that climate change is a ‎ process. We are therefore not talking about adapting to a new standard，but to a constantly shifting set of conditions. This is why, in part at least，the US National Climate Assessment says that：“There is no ‘onesize fits all’ adaptation.” Nevertheless，there are some actions that offer much and carry little risk or cost.‎ Around the world, people are adapting in surprising ways，especially in some poor countries. Floods have become more damaging in Bangladesh in recent decades. Mohammed Rezwan saw opportunity where others saw only disaster. His notforprofit organization runs 100 river boats that serve as floating libraries，schools，and health clinics，and are equipped with solar panels and other communicating facilities. Rezwan is creating floating connectivity(连接) to replace flooded roads and highways. But he is also working at a far more fundamental level：his staff show people how to make floating gardens and fish ponds to prevent starvation during the wet season.‎ Elsewhere in Asia even more astonishing actions are being taken. Chewang Norphel lives in a mountainous region in India, where he is known as the Ice Man. The loss of glaciers (冰川) there due to global warming represents an enormous threat to agriculture. Without the glaciers, water will arrive in the rivers at times when it can damage crops. Norphel's inspiration came from seeing the waste of water over winter, when it was not needed. He directed the wasted water into shallow basins where it froze, and was stored until the spring. His fields of ice supply perfectly timed irrigation(灌溉) water. Having created nine such ice reserves, Norphel calculates that he has stored about 200，000m3 of water. Climate change is a continuing process, so Norphel's ice reserves will not last forever. Warming will overtake them. But he is providing a few years during which the farmers will, perhaps, be able to find other means of adapting.‎ Increasing Earth's reflectiveness can cool the planet. In southern Spain the sudden increase of greenhouses (which reflect light back to space) has changed the warming trend locally, and actually cooled the region. While Spain as a whole is heating up quickly, temperatures near the greenhouses have decreased. This example should act as an inspiration for all cities. By painting buildings white, cities may slow down the warming process.‎ In Peru, local farmers around a mountain with a glacier that has already fallen victim to ‎ climate change have begun painting the entire mountain peak white in the hope that the added reflectiveness will restore the lifegiving ice. The outcome is still far from clear. But the World Bank has included the project on its list of “100 ideas to save the planet”．‎ More ordinary forms of adaptation are happening everywhere. A friend of mine owns an area of land in western Victoria. Over five generations the land has been too wet for cropping. But during the past decade declining rainfall has allowed him to plant highly profitable crops. Farmers in many countries are also adapting like this—either by growing new produce, or by growing the same things differently. This is common sense. But some suggestions for adapting are not. When the polluting industries argue that we've lost the battle to control carbon pollution and have no choice but to adapt, it's a nonsense designed to make the case for business as usual.‎ Human beings will continue to adapt to the changing climate in both ordinary and astonishing ways. But the most sensible form of adaptation is surely to adapt our energy systems to emit less carbon pollution. After all, if we adapt in that way, we may avoid the need to change in so many others.‎ ‎65．The underlined part in Paragraph 2 implies ________．‎ A．adaptation is an everchanging process B．the cost of adaptation varies with time C．global warming affects adaptation forms D．adaptation to climate change is challenging ‎66．What is special with regard to Rezwan's project?‎ A．The project receives government support.‎ B．Different organizations work with each other.‎ C．His organization makes the best of a bad situation.‎ D．The project connects flooded roads and highways.‎ ‎67．What did the Ice Man do to reduce the effect of global warming?‎ A．Storing ice for future use.‎ B．Protecting the glaciers from melting.‎ C．Changing the irrigation time.‎ D．Postponing the melting of the glaciers.‎ ‎68．What do we learn from the Peru example?‎ A．White paint is usually safe for buildings.‎ B．The global warming trend cannot be stopped.‎ C．This country is heating up too quickly.‎ D．Sunlight reflection may relieve global warming.‎ ‎69．According to the author, polluting industries should ________．‎ A．adapt to carbon pollution B．plant highly profitable crops C．leave carbon emission alone D．fight against carbon pollution ‎70．What's the author's preferred solution to global warming?‎ A．Setting up a new standard.‎ B．Reducing carbon emission.‎ C．Adapting to climate change.‎ D．Monitoring polluting industries.‎ ‎【文章大意】 本文是一篇说明文，主要介绍了世界各地适应如今全球变暖的气候的方法。‎ ‎65. A　句意理解题。根据第二段第二句“We are therefore not talking about adapting to a new standard，but to a constantly shifting set of conditions.”可知，我们并不是在讨论适应一个新的标准，而是适应不断变化的条件。据此可以判断，这句话的意思是：适应是一个不断变化的过程。故选A项。‎ ‎66. C　细节理解题。根据第三段第三句“Mohammed Rezwan saw opportunity where others saw only disaster.”以及该段其他内容可知，Rezwan所在的组织充分利用洪水灾害为人们提供便利，故选C项。‎ ‎68.

Developed by two doctors in the US Department of Agriculture, it's an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it's all but impossible to find natural substitutes. The only components required, though, are a 5′×5′ sheet of clear or slightly milky plastic, six feet of plastic tube, and a container—perhaps just a drinking cup—to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.‎ To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher's productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up—and out—the side of the hole.‎ Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet's centre down with a rock. The plastic should now form a cone(圆锥体) with 45degreeangled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup. ‎ The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸发) and collects on the sheet until small drops of water form, run down the material, and fall off into the cup. When the container is full, you can suck the refreshment out through the tube, and won't have to break down the still every time you need a drink. ‎ ‎32．What do we know about the solar still equipment from the first paragraph?‎ A．It's delicate. B．It's expensive.‎ C．It's complex. D．It's portable.‎ ‎33．What does the underlined phrase “the water catcher” in Paragraph 2 refer to?‎ A．The tube. B．The still.‎ C．The hole. D．The cup.‎ ‎34．What is the last step of constructing a working solar still?‎ A．Dig a hole of a certain size. ‎ B．Put the cup in place.‎ C．Weight the sheet's centre down. ‎ D．Cover the hole with the plastic sheet.‎ ‎35．When a solar still works, drops of water come into the cup from ________．‎ A．the plastic tube B．outside the hole C．the open air D．beneath the sheet ‎33. B　词义猜测题。根据文章“Try to make the hole in a damp area to increase the water catcher's productivity.”可知，最好在潮湿的地方挖洞，以提高接水器的工作效率。接水器指的是在潮湿的地方挖洞，在洞的底部放一个杯子，杯子上方用塑料板遮挡。整个装置构成接水器，而不是某个部分。这一题很容易错选D。就算在干燥的地方挖洞，杯子也可以接水，杯子接水的事实并不会因为周围的环境变化而变化，杯子的工作效率是不变的。故选B。‎ ‎34. C　细节理解题。根据文章第三段中的“Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet's centre down with a rock.”可知，最后一步是weighting the sheet's centre down with a rock，即“放一块石头在塑料板的中间，把它压下去”，故选C。‎ ‎5.【科普知识类阅读】【2017·全国卷Ⅱ】‎ C Terrafugia Inc.said Monday that its new flying car has completed its first flight，bringing the company closer to its goal of selling the flying car within the next year. The vehicle—named the Transition—has two seats, four wheels and wings that fold up so it can be driven like a car. The Transition，which flew at 1，400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23gallon tank of gas and burns 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.‎ Around 100 people have already put down a $10，000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don't expect it to show up in too many driveways. It's expected to cost $279，000.And it won't help if you're stuck in traffic. The car needs a runway.‎ Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The government has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition is now going through crash tests to make sure it meets federal safety standards.‎ Mann said Terrafugia was helped by the Federal Aviation Administration's decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes. Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition，a requirement pilots would find relatively easy to meet.‎ ‎28．What is the first paragraph mainly about?‎ A．The basic data of the Transition. ‎ B．The advantages of flying cars.‎ C．The potential market for flying cars. ‎ C．The designers of the Transition.‎ ‎29．Why is the Transition unlikely to show up in too many driveways?‎ A．It causes traffic jams. ‎ B．It is difficult to operate.‎ C．It is very expensive. ‎ D．It burns too much fuel.‎ ‎30．What is the government's attitude to the development of the flying car?‎ A．Cautious. B．Favourable.‎ C．Ambiguous.

Phil Blythe explains: “For many older people, particularly those living alone or in the country, driving is important for preserving their independence, giving them the freedom to get out and about without having to rely on others.‎ ‎“But we all have to accept that as we get older our reactions slow down and this often results in people avoiding any potentially challenging driving conditions and losing confidence in their driving skills. The result is that people stop driving before they really need to.”‎ Dr Amy Guo, the leading researcher on the older driver study, explains: “The DriveLAB is ‎ helping us to understand what the key stress points and difficulties are for older drivers and how we might use technology to address these problems.‎ ‎“For example, most of us would expect older drivers always go slower than everyone else but surprisingly, we found that in 30mph zones they struggled to keep at a constant speed and so were more likely to break the speed limit and be at risk of getting fined. We're looking at the benefits of systems which control their speed as a way of preventing that.‎ ‎“We hope that our work will help with technological solutions(解决方案) to ensure that older drivers stay safer behind the wheel.”‎ ‎32．What is the purpose of the DriveLAB?‎ A．To explore new means of transport.‎ B．To design new types of cars.‎ C．To find out older drivers' problems.‎ D．To teach people traffic rules.‎ ‎33．Why is driving important for older people according to Phil Blythe?‎ A．It keeps them independent.‎ B．It helps them save time.‎ C．It builds up their strength.‎ D．It cures their mental illnesses.‎ ‎34．What do researchers hope to do for older drivers?‎ A．Improve their driving skills.‎ B．Develop driverassist technologies.‎ C．Provide tips on repairing their cars.‎ D．Organize regular physical checkups.‎ ‎35．What is the best title for the text?‎ A．A new model electric car B．A solution to traffic problems C．Driving services for elders D．Keeping older drivers on the road ‎33.

According to a new survey(调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7 to 12yearolds said they felt tired during the day, and 15% said they had fallen asleep at school.‎ How much sleep you need depends a lot on your age. Babies need a lot of rest: Most of them sleep about 18 hours a day! Adults need about eight hours. For most schoolage children, ten hours is ideal (理想的). But the new National Sleep Foundation survey found that 35% of 10 to 12yearolds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.‎ ‎“More children are going to bed with TVs on, and there are more opportunities(机会) to stay awake, with more homework, the Internet and the phone，” says Dr Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers' bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.‎ Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7：25 am to 8：30 am. Students, parents and teachers are pleased with the results.‎ ‎25．What is the new National Sleep Foundation survey on?‎ A. American kids' sleeping habits. ‎ B. Teenagers' sleeprelated diseases.‎ C. Activities to prevent sleeplessness. ‎ D. Learning problems and lack of sleep.‎ ‎26．How many hours of sleep do 11yearolds need every day?‎ A. 7 hours. B. 8 hours. ‎ C. 10 hours. D. 18 hours.‎ ‎27．Why do teenagers go to sleep late according to Carskadon?‎ A. They are affected by certain body chemicals.‎ B. They tend to do things that excite them.‎ C. They follow their parents' examples.‎ D. They don't need to go to school early.‎ ‎27. B　推理判断题。根据第三段“…with more homework…She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep.”可以推断，由于青少年晚上的活动都过于使人兴奋，所以青少年们很难马上静下心来睡觉，从而导致晚睡，故答案选B项。‎ ‎ ‎
