Unit 4　Astronomy：the science of the stars Ⅰ.阅读理解 A ‎[2020·济南市高三学习质量针对性检测]Children in rural areas of Cambodia often suffer from or even die of preventable illnesses because there is not any soap available.‎ In 2014, Samir Lakhani, an American college student, saw the issue while volunteering in a Cambodian village. “I remember quite vividly a mother bathing her newborn baby with laundry powder, which is so harmful to the skin，” said Lakhani.“It's difficult for rural Cambodians to access soap. First is affordability. If you earn only $1.50 every day, you won't spend $1 on a bar of soap. Then comes access. The demand is so low that local shops don't stock soap. The last reason, because many Cambodians don't really understand where diseases come from, they don't know how to prevent them, including using soap.”‎ After figuring out a solution to the problem: the barely used soap in hotels, Lakhani started asking hotels to donate leftover soap.“They were all eager to help，” he explained.‎ Lakhani registered Eco－Soap Bank shortly afterwards. Soon, he received enough funds to hire disadvantaged Cambodian women to collect and reproduce the used soap.‎ ‎ Today, the organization has four recycling centers across the country, providing jobs to 35 local women. And so far, some 174,000 bars of soap have been donated, about 24,000 pounds of soap has been recycled, and hygiene(卫生) has been improved for about 661,000 people.“We are killing_three_birds with one stone，” Lakhani said.‎ When it comes to the future of Eco－Soap Bank, Lakhani said, “We've just scratched the surface. Lack of hygiene is not something unique to Cambodia. The demand for improved hygiene in the developing world is huge, and much remains to be done. We're looking at seven countries to expand to in the near future.”‎ ‎1．Which of the following is not mentioned as the reason why rural Cambodians don't use soap?‎ A．Poverty. B．Inaccessibility.‎ C．Unawareness. D．Tradition.‎ ‎2．What does the underlined part “killing three birds” in Paragraph 5 refer to?‎ - 9 -‎ A．Saving soap, curing diseases and providing education.‎ B．Stopping pollution, providing jobs and inspiring donation.‎ C．Reducing waste, providing employment and improving health.‎ D．Recycling waste, helping charity and improving community hygiene.‎ ‎3．What can we infer about Eco－Soap Bank?‎ A．It won't be long before it expands to the whole world.‎ B．There's little it can do without other countries' assistance.‎ C．It will make greater contributions to the developing world.‎ D．It will soon settle the problem of poor hygiene in Cambodia.‎ ‎4．What do we know about the text?‎ A．Eco－Soap Bank helps improve hygiene.‎ B．Cambodian women have a bright future.‎ C．A US young man calls for helping poor countries.‎ D．Lack of hygiene remains a serious problem in the world.‎ B ‎[2020·贵阳市高三摸底考试]Many of us think, wrongly, that the moon doesn't change. For example, the Tang dynasty poet Zhang Ruoxu once wrote that “Generations have come and passed away; From year to year the moons look alike, old and new.”‎ However, a new study published in the journal Nature Geoscience shows that the moon is in fact slowly shrinking over time. For the study, a group of US scientists examined and analyzed thousands of photographs taken by the NASA's Lunar Reconnaissance Orbiter Camera (月球勘测轨道飞行器照相机). They found that there were lots of faults(断层) on the surface of the moon. These faults were formed by recent movement on the moon.‎ According to NASA, the moon is made up of pieces of rocks with a hot core. The moon continued to expand as it was born. But in this process, it released energy and cooled down. Then it began to shrink, in a way comparable to the shrinking of a grape into a raisin. Over the past several hundred million years, it has become 46 meters “skinnier”. But due to its hard and rocky layer, the moon's surface continues to push up.“Some of these quakes can be fairly strong, around five on the Richter scale(里氏震级)，”said Thomas Watters, a senior scientist at the Smithsonian's National Air and Space Museum in the US.‎ But does that mean the moon is a dangerous place that human shouldn't try to explore and live on in the future? Maybe not, reported The Telegraph.“This isn't - 9 -‎ ‎ anything to worry about. The moon may be shrinking, but not by much. It's not going anywhere，” Watters comforted us.‎ The new discovery proves that the idea that the moon is a dead, boring place is wrong.“We have been to the moon and we've done some great science, but there is still a lot we don't know. The moon is shrinking — we didn't really realize that until recently. It's a much more active and interesting place than we thought and we should explore that，” NASA scientist Nathan Williams said.‎ ‎5．Which point of view about the moon may the writer agree to?‎ A．It stays the same as before.‎ B．It is becoming slightly smaller. ‎ C．It is getting older and older.‎ D．It has passed away.‎ ‎6．What can we learn about the moon from the third paragraph?‎ A．It has become 46 meters fatter due to expanding.‎ B．It has changed from a grape into a raisin in recent years. ‎ C．It quakes even at seven on the Richter scale.‎ D．It has a hot core and releases energy during expanding.‎ ‎7．Who thinks that we needn't worry about the moon?‎ A．Zhang Ruoxu. B．Thomas Watters. ‎ C．Nathan Williams. D．The journalist.‎ ‎8．What does Nathan Williams think of the moon?‎ A．It is a dead and boring place.‎ B．It has lots of faults on the surface.‎ C．It is valuable to do more science.‎ D．It isn't a place where we can live.‎ Ⅱ.完形填空 ‎[2020·贵阳市高三适应性考试(一)]A surveillance (监视) video has become a hit on social media.

It's not going anywhere”可知，Thomas Watters认为我们不必担心月球，尽管月球在缩小，但它并没有缩小很多，故B项正确。‎ ‎8．C　考查推理判断。根据尾段中Nathan Williams说的话“We have been to the moon and we've done some great science... we should explore that”可知，Nathan Williams认为月球有许多我们不了解的东西，值得我们去探索；据此可推知，他认为研究月球是有价值的，故C项正确。‎ Ⅱ.完形填空 体裁：记叙文　题材：社会生活　主题：为救护车让道 ‎【语篇解读】　本文是一篇记叙文，主要讲述了在晚上堵车的隧道里，司机们主动为救护车让出车道，从而使需要急救的病人得以及时医治的感人故事。‎ ‎1．B　根据下文中的“The ambulance was trapped in the traffic jam __3__ after entering the Dongshan Tunnel at 7：46 p．m.”可知，当时隧道里交通拥挤(crowded)。 ‎ ‎2．C　根据下文中的“But when hearing the __4__ of the ambulance, many cars and taxis ahead __5__ and moved to the sides to make way”可推知，当时隧道里的其他车辆听到救护车的声音就为它让路。give way (to sb./sth.)“让……先行”，故选C。‎ ‎3．A　结合空后的“at 7：46 p．m.”可推知，救护车出行时间正值交通高峰期，因此进入隧道不久(shortly)就遭遇了堵车。‎ ‎4．A　根据空前的“hearing”可推知，当时隧道里的其他车辆听到救护车的汽笛声，纷纷让道。whistle“汽笛声”，故选A。‎ ‎5．C　由上文中的“the traffic jam”可知，当时隧道很拥堵，由此可推知，许多车辆放慢速度并移动到一侧为其让路。‎ ‎6．D　根据语境可推知，救护车上的病人情况紧急，需要做急救手术，故选D。‎ ‎7．C　根据上文中的“But when hearing the __4__ of the ambulance, many cars and taxis ahead __5__ and moved to the sides to make way”可知，这一”救生通道”是由隧道里的汽车司机们创造(created)出来的。‎ ‎8．A　根据语境可知，前后句表示逻辑上的因果关系，前因后果。Thanks to “由于”符合语境，故选A。compare with“与……比较”；apart from“除了……外”；but - 9 -‎ ‎ for“要不是”。‎ ‎9．D　根据上文中的“the patient was sent to the hospital in time”并结合语境可推知，病人被及时送到医院，得到了及时的(timely)治疗。‎ ‎10．C　根据上文内容可知，病人得到了及时的治疗，故此处应是那个病人和他的家人对所有让路的司机表达了(conveyed)深深的感激之情。‎ ‎11．A　根据空前的“on the way it had been driven”可推知，此处表示救护车一路开过去。‎ ‎12．C　结合下文中的“he couldn't __33__ how long it would have taken him to make it through... the patient”可推知，此处指的是救护车司机(driver)所说的话。‎ ‎13．A　根据语境可推知，此处表示他难以想象他本应该花多长时间才能穿过去。‎ ‎14．B　根据语境可知，如果救护车被交通堵塞所耽误，那么车上需要急救的病人的情况将会变得很严重(serious)。‎ ‎15．D　根据上文可知，处于交通堵塞中的司机们为救护车让道是一种善举。behavior“行为”符合语境。‎ ‎16．A　根据前一句中的“kind”并结合语境可推知，救护车司机被人们的这种善举感动(touched)了。‎ ‎17．C　根据空前的“expressed”以及下文中的“the milk of human kindness”可推知，网民们也表达了他们对司机们的敬佩(admiration)。‎ ‎18．D　根据空前的“the milk of human kindness”可推知，此处表示正能量。enthusiastic“热情的”；negative“负面的，消极的”；optimistic“乐观的”；positive“积极的”。‎ ‎19．A　根据空后的“Three years ago”可推知，此处表示另一位网友回忆起(recalled)过去的情况。‎ ‎20．B　根据上文的内容可知，本文是一篇正能量的故事。结合上文中的“a similar situation”可推知，此处表示为我们的城市感到自豪。‎ Ⅲ.短文改错 When thousands of lanterns light up the city at night on fifteenth day of the Chinese New Year, I kne the Chinese Lantern Festival has arrived.
