　　Have you ever imagined what kind of car we will be driving in 2020? It will be rather different from the type we know today, with the next 20, years bringing greater change than the past 50．The people who will be designing the models of tomorrow believe that environmental problems may well accelerate(促进，加快)the pace of the car's development. Today they are students on the transport design course at London's Royal College of Art.

　　Their vision is of a machine with three wheels instead of four, electrically powered, environmentally clean, and able to drive itself along “intelligent” roads equipped with built－in(内置的)power supplies. Future cars will pick up their fuel during long journeys from a power source built into the road, or store it in small quantities for traveling in the city.

　　Instead of today's seating arrangements－two in front, two or three behind, all facing forward－the 2010 car will have a versatile interior with adults and children in a family circle.

　　This view of the future car is based on a much more sophisticated(复杂的)road system, with strips built into motorways to supply power to vehicles passing along them. Cars will not need drivers, because computers will provide safe driving control and route finding. All the driver will have to do is to say where to go and the computer will do the rest. It will become impossible for cars to crash into one another. The technology already exists for the car to become a true automobile.

1．A future car will use electrical power, because it is ________.

[　　]

A．safer

B．cheaper

C．cleaner

D．faster

2．A future car will have all the following features(特点)EXCEPT ________.

[　　]

A．being three－wheeled

B．running without anyone in it

C．driving along special roads

D．with a versatile seating arrangement

3．The underlined sentence “with strips built… passing along them” means that there will be ________.

[　　]

A．many traffic lights to control the speed of future cars

B．many street posts to indicate directions for drivers

C．many power sources along roads supplying power to cars

D．many stop marks along the street to stop cars

4．What is the main idea of the text?

[　　]

A．Future cars will be completely different from the automobiles we know today.

B．The design of future cars will be more sophisticated.

C．Because of the new type of cars, our future environment will become cleaner.

D．The road system will become more sophisticated than it is today.

Answer 1

答案：C;B;C;A
解析：

1．C　　从第一段中间谈到的“environmental problems”和第二段首句“electrically powered，environmentally clean”可知。 　　2．B　　从文章第二段首句和第三段首句可知A、C、D项均为未来汽车的特点。文中“drive itself”为“自动驾驶”之意，并非无人在车内，故选B项。 　　3．C　　由上下文可知，未来的道路系统将很高级，在机动车道上将设有为在中各上行驶的车辆提供能量的装置，故选C项。 　　4．A　　全文主要讲述未来汽车在设计、功用、能源供应及操作方面与现在的汽车大不相同，故A项正确。
