　　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(促進(jìn)，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(內(nèi)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(復(fù)雜的)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(特點(diǎn))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　　從第一段中間談到的“environmental problems”和第二段首句“electrically powered，environmentally clean”可知。 　　2．B　　從文章第二段首句和第三段首句可知A、C、D項(xiàng)均為未來汽車的特點(diǎn)。文中“drive itself”為“自動(dòng)駕駛”之意，并非無人在車內(nèi)，故選B項(xiàng)。 　　3．C　　由上下文可知，未來的道路系統(tǒng)將很高級(jí)，在機(jī)動(dòng)車道上將設(shè)有為在中各上行駛的車輛提供能量的裝置，故選C項(xiàng)。 　　4．A　　全文主要講述未來汽車在設(shè)計(jì)、功用、能源供應(yīng)及操作方面與現(xiàn)在的汽車大不相同，故A項(xiàng)正確。
