未來汽車

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 (擁擠). One proposed solution to this problem is the automated highway system.

When the auto enters the highway system, a retractable (可伸縮的) 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 (蜂鳴器) 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.

1.[A] 推斷題。從第2段首句可以看出第2段主要講未來汽車的變化方向。該段第2 、3句說它將變得更小巧、安全、節(jié)能，給它提供動力的將不再是汽油發(fā)動機。而第3段也著重展望了未來汽車動力系統(tǒng)的新模式，故未來汽車一個最重要的改進就在于它的能量來源，故答案為A。

2.[C] 事實細節(jié)題。第3段首句提到，未來的汽車仍將是令城市交通擁擠的主要問題而這也是作者最為關(guān)心的問題，C之相符。其他各項在文章中都提到過，但并非the main problem，故排除。

3.[A] 事實細節(jié)題。文章第4段第1、2句提到，當汽車進入高速公路系統(tǒng)后,一只自動伸縮臂就會從車上伸下來，搭上一根鐵軌，這根鐵軌類似于為地鐵列車提供電能的那些鐵軌，一旦汽車連接到rail上，它就可以從中獲得電能。因此A正確。

4.[D] 事實細節(jié)題。最后一段首句提到，司機將通過電話發(fā)出指令，把目的地輸入系統(tǒng)。由此可見，司機可以使用電話來告知系統(tǒng)他的目的地，故選D。A、B、C在文中沒有提及。

5.[C] 推斷題。根據(jù)第2段和最后一段(特別是最后一句)不難看出作者對于汽車發(fā)展的前景持樂觀態(tài)度，故選C。
