【解析】

本文介绍了将来的一种新的小型汽车。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，不适于长途旅行，如果将来和现在的通用车型并存的话，会需要两种公路。

1.】A 细节理解题。题意：为什么今天空气中有许多污染？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。

2.】D 细节理解题。题意：今天通常的车怎样？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。

3.】B 推理判断题。题意：下面哪一个陈述不对？根据短文内容，未来的新型小车不适合长途旅行，因此长途旅行还是需要大车。故B不对。

4.】D 细节理解题。题意：为什么街道将不会更拥挤？由第一段最后的句子：There will also be more space for parking in cities, and the streets will be less crowded．因为未来的车会更小，停车的地方需要更少，街道将不会更挤。故选D。

5.】C 细节理解题。题意：为什么将来需要两种公路？根据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。
