A kind of little cars may take the place of today’s big ones many years later. If everyone drives such cars in the future, there will be less pollution in the air. There will also be more space for parking in cities, and the streets will be less crowded.
The little cars of the future will cost less. Driving will be safer, too, since these little cars can go only 65 kilometers an hour. The cars of the future will be fine for going around a city, but they will not be useful for a long way. Little cars will go 450 kilometers before they need to stop for more gasoline (汽油). If big cars are still used with the small ones, two kinds of roads will be needed in the future. Some roads will be needed for the big, faster cars and other roads will be needed for the small, slower ones.

C．small cars will go 450 kilometers before they need to stop for more gasoline

D．the usual size of cars today is too small

小题2:.The usual size of cars today is _____.

A．much smaller than the future one	B．as big as the future ones
C．as small as the future ones	D．bigger than the future ones

小题3:.Two kinds of roads will be needed in the future because _____.

小题1:A
小题2:D
小题3:C

解析

试题分析：
小题1:.根据If everyone drives such cars in the future, there will be less pollution in the air.可知现在空气污染严重的原因是很多人开到大汽车，故选A。
小题2:根据A kind of little cars may take the place of today’s big ones many years later.现今的汽车尺寸及通常的汽车尺寸，故选D，通常的汽车尺寸比将来的大。
小题3:根据下文Some roads will be needed for the big, faster cars and other roads will be needed for the small, slower ones.可知由于车速不同，故需要两种车道，故选C。
点评：本文较少了将来发展的一种小型汽车。由于这种汽车体型小，能耗也小，故能降低空气污染。但是这种汽车车速低，如果将来和现在的通用车型并存的话，会需要两种公路。阅读中注意两种车型的不同特点，注意分析他们的各自的优缺点，及对社会环境的影响。
