导读：本文为学生们收集了一篇英语四级阅读练习题，想要提高自己的同学快点学习起来。在做阅读练习的时候要抓住文章的中心思想，就要找它的主题句，一般文章的主题句，在第一段的第一句，有时也有可能在第二段或最后一段，所以阅读时要特别注意文章的开头和结尾，但也有可能主题句不明显，难找，这时就应注意句子间的逻辑关系。如果文章所表达的意思是对某个句子进行说明，描写或解释，那么该句肯定是主题句，从而明确文章的中心思想。

未来汽车

　　Some pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, thinkthe auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future.

　　The motorcar will undoubtedly change significantly over the next 30 years. It should become smaller, safer,and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.

　　Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion (拥挤). One proposed solution to this problem is the automated highway system.

　　When the auto enters the highway system, a retractable (可伸缩的) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail,the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car’s movements.

　　The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer (蜂鸣器) that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.
