Question

【题目】根据短文理解, 完成下了各题。
B
Each year there is an increasing number of cars on the roads and streets as millions of new cars and trucks are produced. One out of every six Americans works at putting together the parts of the cars, driving trucks, building roads, or filling car with gas. Americans won’t live without cars!
Most Americans would find it hard to think what life could look like without a car. However, some have realized the serious problem of the air pollution caused by the car. The polluted air becomes poisonous and dangerous to health.
One way to get rid of the polluted car is to design a car that does not pollute. That's what several of the large car factories have been trying to do. But to build a clean car is easier said than done. Progress in this field has been slow.
Another way is to take the place of car engine （发动机）by something else. Inventors are now working on steam cars as well as electric cars. Many makers believe that it will take years to develop a practical model that pleases man.
To prevent the world from being polluted by car, we'll have to make some changes. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and to go to work by bicycle. Bicycling is thought to help keep the air clean.
But this change doesn't come easily—a large number of workers may find themselves without jobs if a car factory closes down. Thus the problem of air pollution would become less important than that of unemployment.
Although cars have led us to a better life, they have also brought us new problems.

【解析】在美国，汽车是人们生活中的重要一部分，美国人已经到了没有汽车不能生活的地步。但是汽车带来的空气污染也越来越严重。如果解决这个问题是本文讨论的主要内容。
（1）细节理解。由第三段中的第一二句话One way to get rid of the polluted car is to design a car that does not pollute. That’s what several of the large car factories have been trying to do.可知消除空气污染的一个方法就是设计不污染的汽车，因此选D项。
（2）细节理解。由倒数第二段第一句话a large number of workers may find themselves without jobs if a car factory closes down可知汽车工厂关闭了那么大量的工人会发现自己没工作了。故选A项。
（3）写作意图。文章最后一句话点题，汽车不仅给人们带来了便利，同时也带来一些严重的污染。故选D。
（4）细节理解。A.六分之一的美国工人在汽车工厂工作，根据第一段One out of every six Americans works at putting together the parts of the cars, driving trucks, building roads, or filling car with gas.可知错误。B.消除空气污染的最好办法是用别的东西更换汽车发动机。根据第四段可知是一种方法而不是最好方法。D.自行车会代替汽车，根据第五段可知表达错误。C.美国人的生活不容易改变。根据全文内容可知如果减少汽车会带来就业生活等一系列问题，所以正确答案是C项。
（5）主旨大意。全文主要讲述了汽车及其带来的环境污染等问题，故正确答案应为B项。
