问题    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, think the 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. One proposed solution to this problem is the automated highway system.
   When the auto enters the highway system, a retractable 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 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. [br] What is the author’s main concern?
选项 A、How to render automobiles pollution-free.
B、How to make smaller and safer automobiles.
C、How to solve the problem of traffic jams.
D、How to develop an automated subway system.
答案 C
解析 根据第三段中的“…the auto in the future will be the main problem in urban traffic congestion”可知，作者最为关心的还是将来汽车造成的城市交通拥挤问题。因此，[C]正确。文章第二段最后一句告诉我们未来的汽车将成为无污染的汽车，但并没有进一步讨论这个问题，故，[A]不符合题意。文章也没有深入讨论汽车“becomes smaller，safer”等这些改变，所以，[B]也不符合题意。文章比较详细地谈了“automated subway system”，但它的目的是为了解决城市道路交通拥挤问题，故，[D]也不符合题意。
