Some experts feel that the automobile is to “die”. They see a day in the not­too­distant future when all autos will be abandoned and allowed to bee rotten iron and steel rubbish.     【小题1】     They think that the car will remain a leading means of urban travel in the near future.
_【小题2】_ It should bee smaller, safer, and more money­saving, and should not be powered by the petrol engine. The car of the future should be far more pollution­free than present types.
Regardless of its power source, the auto in the future will still be the main problem in urban traffic jam. _【小题3】_
When the auto enters the freeway system, a retractable arm, which can be moved inwards or backwards, will drop from the auto and touch a rail that is similar to the subway trains electrically powered from the system, and control of the vehicle will pass to a central puter. 【小题4】_
The driver will use a telephone to dial instructions about his destination into the system. The puter will calculate the best route, and reserve space for the car all the way to the correct exit from the freeway. _【小题5】_ It is guessed that an automated freeway will be able to handle 10,000 vehicles per hour, pared with the 1,500 to 2,000 vehicles that can be carried by a present­day freeway.A.Other authorities, however, think the auto is here to stay.B.The puter will then monitor all of the car's movements.C.One proposed solution to this problem is the automated freeway system.D.Experts have different views on what role autos will play in the near future.E.The motorcar will undoubtedly change significantly over the next 30 years.
F.Drivers in the freeway system can sit back and do nothing but control the direction.
G.The driver will then be free to relax and wait for the sound speaker that will warn him of his ing exit.

(答案→)A 
解析:本文属于科普知识类,为大家预测了将来的汽车是什么样子,以及怎样操控它。
【小题1】A 首先根据文章开头的“Some experts...”可知与A项的“Other authorities”构成some...others的结构;其次,根据后文说到“...remain a leading means of urban travel”可知,本句和前面说的“汽车消失”形成对比。故选A项。
【小题2】E 根据空后的“It should bee smaller,safer,and more money­saving,and should not be powered by the petrol engine.”可知选E项。
【小题3】C 根据空前的“the main problem”及后文的“the freeway system”可知C项起到了承上启下的作用。
【小题4】B 根据空前的“control of the vehicle will pass to a central puter”可知选B项。
【小题5】G 本段都是讲述电脑控制汽车是如何运行的,故选G项。
