必修二 Unit 4 高考拆组训练 阅读理解组块专练——练速度 ‎(限时：30分钟)‎ Ⅰ.阅读理解 A In an effort to stop poaching (偷猎) and protect endangered species, people are using technology previously created to discover stars.Claire Burke, who led the project, says the application of the starhunting tech has so far paid off big for conservation.“Since animals and humans in thermal imagery (热成像) ‘glow’ in the same way as stars in space, we have been able to combine the technical expertise of astronomers with the conservation knowledge of ecologists to develop a system to find the animals or poachers automatically，” she said in a statement.‎ In addition to species identification, the software can also provide an overview of health.Burke said that diseased or injured animals give off a different thermal imagery than the healthy ones.“The real advantage this gives you is that if you know how many animals you have and where they are and what kind of health they are in, then you can work out a good conservation strategy for looking after them，” she said.‎ The following is a post written by Burke on Twitter: More animals for the thermal imagery library.Thanks to Chester Zoo Science @ScienceatCZ for letting us observe their fantastic creatures.Images are giraffes, Indian elephants, and fruit bats.— Claire Burke (@CBurkeSci) October 27, 2017.‎ To train the software on a wide variety of heat signatures from different species, the team of researchers spent time collecting thermal imagery of animals.Their first field trial to detect Riverine rabbits, one of the most endangered mammals in the world (with only 500 living adults left in the wild), was a complete success.“The rabbits are very small, so we flew the drone (无人机) quite low to the ground at a height of 20 meters (65 feet)．Although this limited the area we could cover with the drone, we managed to see the rabbit five times，” said Burke.“Given that there have only been about 1,000 times people have seen Riverine rabbits, it was a real success.”‎ 语篇解读：本文是一篇说明文。为保护濒危动物、防止偷猎，生态环境保护者利用天体物理学中用来寻找星星的技术来定位动物和偷猎者。‎ ‎1．What can people decide by observing the thermal imagery of the animals?‎ A．What the animals are doing.‎ B．When the animals need help.‎ C．Whether the animals are healthy.‎ D．Why the animals are in danger.‎ 解析：选C　细节理解题。根据第二段“In addition to species identification, the software can also provide an overview of health.”可知，使用这种热成像技术，不仅可以观测到动物所属的物种，而且还能观测到它们的健康状况。‎ ‎2．What can we learn from Burke's post on Twitter?‎ A．It is better for animals to live in the zoo.‎ B．More animals are becoming endangered.‎ C．Zoos help a lot in protecting endangered animals.‎ D．The researchers are collecting data for the software.‎ 解析：选D　细节理解题。根据Burke在Twitter上发布的这条信息可知，科学家们正在为利用这种技术所开发的软件收集各种动物的数据信息。‎ ‎3．What did the researchers find out after detecting the Riverine rabbits?‎ A．The number of them is decreasing.‎ B．It is difficult for people to identify them.‎ C．There are more of them than people thought.‎ D．It is easier to find them using the hightech tool.‎ 解析：选D　推理判断题。根据最后两句可知，南非山兔非常稀有，研究者们使用这种新技术观察到南非山兔5次，相比起过去人们共观察到南非山兔大约1 000次，这个比率已经非常高了。‎ ‎4．What is the text mainly about?‎ A．Technology has helped a lot in helping the endangered animals.‎ B．Scientists use stargazing tools to protect endangered species.‎ C．What we should do to protect the endangered animals.‎ D．Scientists are working hard to protect the environment.‎ 解析：选B　主旨大意题。本文介绍了环境保护者利用天文学中用来寻找星星的工具来对濒危动物实施保护。‎ B Some pigs tend to be optimistic while others are pessimistic, according to a new research that is meaningful to animal welfare.The study, published in the journal Biology Letters, is the first to show that mood and personality interact in an animal, influencing judgment.‎ Asher, a researcher at the University of Newcastle's Institute of Neuroscience, and her team housed groups of pigs in two types of environment.One reflected standard commercial conditions and the other was cushier with more space and plenty of soft, deep ‎ straw.After the pigs got accustomed to these new homes over a few weeks, the researchers picked 18 pigs from each type to train and test their judgment.‎ ‎“To do this, we trained each pig.In one corner of a training room there would be a bowl with chocolate sweets — pigs love them — and at the opposite side of the room there would be a bowl containing coffee beans, which pigs find bittertasting，” a researcher said.‎ Over a number of training trials, pigs learned to go to the bowl reliably when it was in the corner where they had figured out to expect chocolate sweets.On the contrary, they quickly learned to avoid the bowl when it was in the corner where they would expect to find the coffee beans.‎ The researchers next placed an unfamiliar bowl in different locations, to see how the pigs would react.Some gaily dashed to the bowl no matter what was inside, showing optimism that it would contain their favorite sweets.Others, however, behaved as though they expected it to contain coffee beans, displaying pessimism.‎ The findings suggest that a onesizefitsall answer to animal welfare issues does not exist.Even if pigs are just equal to bacon or other meat for some people, there is still cause for concern.Studies have suggested that how an animal is treated during its lifetime can directly affect meat quality and taste.‎ ‎5．What was the study trying to figure out?‎ A．How to make pigs happier.‎ B．The similarities between humans and pigs.‎ C．How living environment affected pigs' mood.‎ D．How pigs' mood and personality affected their judgment.‎ 解析：选D　细节理解题。根据文章第一段第二句“The study, published in the journal ... influencing judgment.”可知，选项D正确。‎ ‎6．What does the underlined word “cushier” in Paragraph 2 mean?‎ A．Simple.　 B．More comfortable.‎ C．Unpractical. D．Less free.‎ 解析：选B　词义猜测题。根据画线词后的“more space and plenty of soft, deep straw”可知，另一个环境很舒适。所以选项B正确。‎ ‎7．What do the findings of the new research imply?‎ A．People should treat pigs equally.‎ B．People's health relies on meat quality.‎ C．People should meet pigs' various needs.‎ D．People's attitude toward pigs is totally wrong.‎ 解析：‎ 选C　推理判断题。根据最后一段尤其是最后一句可推知，要想获得高质量和口感好的猪肉，人们应当满足猪的多种需要。所以选项C正确。‎ C Recently, my teenage son gave me a great insight into my writing career. He plays the online multiplayer game Minecraft, in which players build vast structures while battling the occasional zombie at night.‎ ‎“How do you win the game？” I asked him.‎ He rolled his eyes, the way only teens can.‎ ‎“There is no winning the game, mom，” he said. “It's about the experience. It's all about the journey.”‎ Well said, Evan. I so often forget this truth.‎ In writing, there is no arriving. There's always the drive to write a better article, blog post, poem, or novel, next time. There is no “done”．‎ What sights do you want to see on your journey? Where do you want to be sure to go? These are the questions I'm asking myself as I consider my plans for next year.‎ If we've written well, what we leave behind will be part of our legacy, hopefully helping others long after we're gone. I find that thought comforting.‎ You could make your way to new signatures in magazines, or even to new places on the map. I have a friend who was flown to Denmark to meet with Lego because they liked his writing. I recently read about a woman whose writing got her a position in Singapore from CocaCola.‎ So here's a writing journey for all of us that's full of breathtaking sights, unexpected turns, wonderful friends, and opportunities to grow and improve our craft.‎ As we enter the new year, I'm going to try to remember my writingcareer focus — the places I want to be sure to visit on my way. Most of all, I'm going to work on letting go of my feelings of “falling behind” or not being “there” yet, and try to enjoy every moment of my wonderful writer's life.‎ 语篇解读：本文是一篇议论文，主要论述了写作重要的不是结果，而是过程，我们应享受写作过程中的每一刻。‎ ‎8．What got the author thinking about her writing career?‎ A．Her son's playing games online.‎ B．Her son's words.‎ C．Her experience of a journey.‎ D．Her son's winning the game.‎ 解析：选B　推理判断题。根据第一段第一句和第四段后两句可推知，作者儿子的话使她重新思考自己的写作生涯。故答案选B。‎ ‎9．The author mentioned Lego and CocaCola to show that ________.‎ A．writings should appeal to companies B．there are great writers in wellknown companies C．writers should go to new places on the map D．great writers can make a difference 解析：选D　推理判断题。第一个例子是指，作者的朋友飞到丹麦去见乐高公司的员工，因为他们喜欢他的作品；第二个例子是指，一位妇女的写作作品使得她在新加坡的可口可乐公司获得了一席之地；由此并结合倒数第二段可推知，作者提到Lego和CocaCola旨在说明伟大的作家能够产生重要影响。故答案选D。‎ ‎10．What can be a suitable title for the text?‎ A．My Smart Son B．My Writing Career C．The Writing Journey Matters D．My Son Teaches Me Much 解析：选C　标题归纳题。纵观全文可知，儿子的话使作者领悟到写作过程才是最重要的，并且她打算今后要珍惜写作过程中的每一刻。C项“写作过程很重要”概括了文章大意，适合做标题。故答案选C。‎ Ⅱ.阅读七选五 As a teenager, convincing yourself to stay away from electronics to plant a garden might not be an easy task.__1__ This is because whether you have the yard space to grow a garden or there are community gardens in your area, getting yourself involved has several benefits.‎ For example, caring for plants helps you develop responsibility.Also you can gain a sense of accomplishment and selfconfidence as you raise them from small sprouts (苗芽)up through full blooming (盛开的) beauties.What's more, gardening has been shown to reduce stress and depression.__2__ ‎ In addition, outdoor time promotes exercise.Gardening offers fresh air, sunshine, and exercise, even to the teen who generally avoids physical activity.__3__ So you may actually enjoy growing potatoes, or any other kinds of plants, for these benefits.‎ ‎__4__ If you're looking for a new way that doesn't involve arguing to bond with your family, consider plants.You can have a good family time by taking care of plants together in your family garden.‎ Finally, growing food can encourage healthier eating habits.__5__ Tasting the fruits through your own efforts also inspires you to eat more of the items you grow yourself.What's more, a backyard garden is also an excellent way for you to ensure that ‎ what you eat is organic (有机的)．‎ A．Gardening also offers a great way to connect.‎ B．Meanwhile, it can improve your ability to focus.‎ C．But it's always a good idea to learn to love gardening.‎ D．You will experience the benefits of your efforts over time.‎ E．Sowing seeds and planting seedlings also require movement.‎ F．Try to become knowledgeable about making wise food choices for life.‎ G．Teens who grow their own food are more likely to enjoy healthy eating.‎ ‎1．选C　让自己远离电子产品去从事园艺是不易的，但园艺总是值得去爱的，因为它有许多好处。‎ ‎2．选B　根据空前的“has been shown to reduce stress and depression”可推断出，此处在介绍园艺在人的心理层面上的好处，园艺已被证明可以减轻压力和抑郁；同时，它也可以提高你的专注力。‎ ‎3．选E　园艺可以给缺少身体锻炼的青少年提供锻炼机会，播种和种植幼苗也需要运动。‎ ‎4．选A　根据空后的“bond with your family”可知，如果你想找一种不会牵涉到争吵的方式与家人建立良好的关系，那么请考虑园艺。因此，该段主要讲园艺是一种与家人建立良好关系的方式。‎ ‎5．选G　该段第一句提到“种植水果或蔬菜能够促进更健康的饮食习惯”，G选项提到“种植水果或蔬菜的青少年更可能享受健康的饮食习惯”，该句是对第一句进一步的解释。‎
