课时规范训练(九) Part 1 阅读完形组合准度练 (建议用时40′) Ⅰ.阅读理解(共8小题；每小题2分，满分16分) A Car companies such as Tesla and Nissan have been leading the way in electric car technology.What makes these cars “green” is that because they run on electricity instead of gasoline，they do not give off any polluting greenhouse gases.The Toyota Mirai is also a kind of green car，since it is powered by a hydrogen fuel (氢燃料) battery. Hydrogen，as you know，exists in large quantities on the earth.It was used to power gaslights for centuries before electric lights came along.Hydrogen fuel can be made from many sources including water，natural gas and even rubbish.In terms of energy contained，9.5kg of hydrogen is equal to 25kg of gasoline.According to Toyota，the two tanks on the Mirai hold 5kg of hydrogen，and can cover a distance of over 300 miles.This is twice the output of gasoline cars. In a hydrogen fuel battery，the one proton (质子) and one electron in a hydrogen atom are broken up.While the electrons power the car，the positively charged hydrogen proton combines with the oxygen atom to produce water.The process also produces a lot of heat which turns this water into water vapor.This is the reason that cars running on hydrogen fuel batteries give off water vapor from their exhaust pipes when running. According to Toyota，it takes only 5 minutes to refill a hydrogen tank，which is much quicker than charging electric cars.However，the biggest challenge for the company is the availability of hydrogen charging stations.California and the New England states are in the process of building a hydrogen superhighway—with charging stations along the way.Countries like Germany，Japan and UK are also adding more charging stations. The Toyota Mirai will be available in the U．S.in the second half of 2015 for $58，000.This hydrogen fueled car will probably take the place of gasoline cars in the near future.After all，it is an energy saving and environment friendly car. 1．According to the text，hydrogen ． A．can only be used as a fuel for cars B．is a newly discovered energy source C．provides more energy than an equal amount of gasoline D．will soon become the main fuel for most of Toyota's cars 2．The third paragraph is mainly about ． A．water vapor and weather B．how the Toyota Mirai works C．different types of batteries D．why hydrogen is very popular 3．What can we learn about the Toyota Mirai A．It runs on both gasoline and hydrogen. B．It has become a great threat to electric cars. C．It gives off only a few polluting greenhouse gases. D．It may sell well with more charging stations around. 4．What would be the best title for the text A．A new wave of green cars B．The benefits of electric cars C．Tesla: a leading car company D．Hydrogen: future energy sources 【语篇解读】 本文是说明文。文章主要介绍了丰田公司即将推出的一款新能源汽车———Mirai。 1．解析：选C。细节理解题。由第二段中的In terms of energy contained，9.5kg of hydrogen is equal ... ...
