Question

【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Each year there is an increasing number of cars on 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 cars, driving trucks, building roads or filling cars and trucks with gas. 【1】

Most Americans would find it hard to imagine what life would look like without cars. 【2】 The polluted air becomes poisonous and dangerous to health.

【3】 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 the car engine by something else. 【4】 Many makers believe that it will take years to develop a practical model that pleases man.

To prevent the world from being polluted by cars, we’ll have to make some changes in the way many of us live. Americans, for example, have to cut down on the number of their total cars. They are encouraged to travel and go to work by bicycle. Bicycling is thought to help keep the air clean. But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down. 【5】

Although cars have led us to a better life, they have also brought us new problems.

A. Thus the problem of air pollution would become less important than that of unemployment.

B. Americans know cars very well.

C. However, some have realized the serious problems of the air pollution that is caused by cars.

D. One way to get rid of the polluted air is to build a car that does not pollute.

E. However, the number of vehicles（车辆） has continued to increase in recent years.

F. Americans won’t live without cars！

G. Inventors are now working on steam car as well as electric cars.

【3】D

【4】G

【5】A

【解析】

试题分析：美国人的生活和汽车息息相关，但由汽车导致的大气污染问题也很严重。针对这一问题，本文讨论了一些解决方法例如生产使用情节能源的汽车，或者以自行车代替汽车等。

【1】F 考查上下文联系。根据前文One out of every six Americans works at putting together the parts of cars, driving trucks, building roads or filling cars and trucks with gas.可知，美国人的生活与汽车息息相关，而选项F意为“美国人离开了汽车简直活不下去”，正是对这一现象的一个总结，也与下文Most Americans would find it hard to imagine what life would look like without cars相关联，故选F。

【2】C 考查上下文联系。分析语境可知，此处前文说明大多数美国人对汽车的依赖，而后文The polluted air becomes poisonous and dangerous to health.提到的是大气污染。而选项C在语境上起到了承上启下的作用，符合语境，故选C。

【3】D 考查上下文联系。分析后文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可知，几个大的汽车工厂一直努力想生产清洁无污染的汽车。由此可以推断that指的是build a clean car，浏览选项发现D选项与之对应，符合语境，故选D。

【4】G 考查上下文联系。前文讲述另一种方法是用其他东西代替汽车发动机，后文提到许多制造商相信需要一些年来开发一种人们喜欢的实用的样车，故A项“发明家们正在开发蒸汽车和电动汽车”连接上下文，故选G。

【5】A 考查上下文联系。分析前文But this change does not come easily. A large number of workers may find themselves without jobs if a car factory closes down可知，这种转变不会轻易到来，因为如果一个汽车工厂倒闭，将会有许多工人失业。选项A中将环境污染问题与工人失业问题进行比较，符合语境，故选A。
