1、Unit 3 Inventors and inventions课时作业.阅读理解(2020黄冈市高三质量检测)One of the things that makes your smartphone so smart is that if you pull it out in the sun, it senses thatand dials up the screen brightness to compensate. But its not a perfect solution.“First of all, its still not bright enoughyou have to rem
2、ember how respectable sunlight is.” said ShinTson Wu, a physicist at the University of Central Florida. The other problem, he says of the brightened screen, is it kills the battery. So Wu and colleagues have produced a batterysparing alternative: an antireflective screencoating, based on the eyes of
3、 moths. “Nature is so rich! We can learn a lot from nature.” The thing Wu and others have learned about moth eyes, is that theyre uneven, dotted with tiny projections. That uneven surface reduces the reflection of light off their eyesthought to help the bugs escape predators (捕食者), and see better in
4、 low light. So Wu and his team built a similar surface with tiny dimples (凹), to cut down on glare. He says the dimpled coating could improve the readability of a screen by five to 10 times, compared to a normal smartphone screen. The details are in the journal Optica.The tech hasnt been commerciali
5、zed yet, and that could take a few years, which gives researchers time to take advantage of another property of these surfaces: theyre flexible, meaning the possibility of bendable displays. Combine that with the bendy batteries we reported on in a recent podcast (播客), and it looks the smartphones o
6、f the future could be set for a real transformation. 篇章导读：本文是一篇说明文。飞蛾眼睛的凹凸不平激发了研究者开发一种未来可能会变形的手机屏幕。1Why do the researchers develop the antireflective screencoating?ATo brighten the screen.BTo make profits.CTo take in the sunlight.DTo save the use of battery.答案：D细节理解题。根据第二段中的“The other problem, he sa

9、rface reduces the reflection of light off their eyesthought to help the bugs escape predators (捕食者), and see better in low light. So Wu and his team built a similar surface with tiny dimples (凹), to cut down on glare.”可知是这种手机屏幕凹凸不平的表面减少了光的反射。4What do the researchers expect of the screen?AItll transf

The
11、y begancarrying passengers Monday in Germanys northern Lower Saxony state. The new train will run 100kilometer trips and can travel up to 140 kilometers an hour.A French railroad company called Alstom built the two trains. Team in Germany andFrance cooperated on the project, which was supported by t
12、he German government. The new train model, called the Coradia iLint, signals the beginning of efforts in Germany and other nations to move away from pollutionproducing diesel (柴油) trains.The Coradia iLint is designed to run on nonelectrified train lines with low levels of noise.It uses a process tha
13、t combines hydrogen and oxygen to produce electrical power. If the system produces more energy than the train needs at that time, it can store the extra energy in batteries. The only emissions (排放物) are water and steam.A single tank of hydrogen can run a Coradia iLint train for about 1,000 kilometer
14、s. This is very similar to the distance a dieselpowered train can run on with a single tank.Hydrogenpowered trains cost more than diesel trains to build. But Alstom officials say the operating costs are much lower. The company plans to provide another 14 Coradia iLint trains to Lower Saxony by 2021.
15、 The head of railroad operations in the area, Carmen Schwabl, praised replacing diesel trains with hydrogen. She said the move was an important first step in using cleanburning technologies to reach climate protection goals. Officials say the areas many wind turbines (涡轮机) will produce part of the e
16、nergy to create the hydrogen to power the trains.Alstom says several other European countries have also expressed interest in developing hydrogen train systems. France has already said it wants its first hydrogen train to be operating by 2022.5Why did Germany build the new trains?ATo replace diesel
17、trains. BTo carry more passengers.CTo make traveling much easier. DTo develop friendship with France.答案：A细节理解题。根据文中第二段最后一句可知，建造新型火车的目的是move away from pollutionproducing diesel (柴油) trains，故选择A。6What is one advantage of the Coradia iLint?AIt runs without making any noise.BIt doesnt use electrical pow
18、er. CIt costs much less to run. DIt is cheaper to make it.答案：C细节理解题。根据文中倒数第四段中的“the operating costs are much lower”可知，氢动力火车的运行成本更低，故答案为C。7It can be concluded that hydrogen trains _.Aare widely used Bare environmentally friendlyCcan stop air pollution Dcan produce water and oxygen答案：B推理判断题。由文中第四段最后一句
19、话可知，新型氢动力火车的排放物只是水和蒸汽，所以是环保的，故B为正确答案。8What might be the best title for the text?ASaving Natural Resources BEfforts to Reduce EmissionsCWorlds First Hydrogen Trains DA New Way to Make Electricity答案：C标题判断题。本文主要介绍的是一种新型的氢动力火车的研制及其特点，故C 项符合文章大意，最适合作标题。.七选五You have some great ideas.

25、文。作者就如何培养创造性思维给出了有效的建议。1A设空处前面提到人们因为朋友说的话或者他们自己觉得只有少数人才能成为具有创造力的天才而使自己的想法没有为大家所知。下文主要阐述了一些可以提高创造性思维的方法，因此，空处应该选一个承上启下的句子，故A项“但是实际上，这种想法一点儿都不对。”符合语境。2G设空处前一句将创造力比喻成需要被锻炼的肌肉，G项中的“like a muscle”与前文相呼应和承接，另结合句意，可确定G项符合语境。3C该段最后一句表述你知道的东西越多，你想知道的就会越多，你的大脑就越会得到锻炼。结合设空后下一句说明各种了解信息的方法可推知C项“因此，每天得到尽可能多的信息是很重
26、要的”符合语境。4F设空处前一句提到每天要尝试新事物，而F项“你的经历让你了解有关你周围的世界和人的更多信息”正是这样做的结果。5D由设空处前文中的“begin thinking beyond your limits from today”和后文中的“your idea might be the next great idea to change the world”可知，D项“你将很快拥有一种充满趣味且令人兴奋的刺激生活”符合语境。.语法填空(2020安徽省合肥市八校高三第一次联考)Chinas research icebreaker Xuelong, _1_ 126 crew member
