Question

英语文章翻译，求解答。

A kind of little cars may some day take the place of today's ones. If everyone drives such cars in the future, there will be less pollution in the car. There will also be more space for parking cars in cities, and the streets will be less crowded. Three such cars can fit in the space now needed for one car of the usual size.
The little cars will cost much less to own and to drive. Driving will be safer, too, as these little cars can go only 65 kilometers an hour. The cars of the future will be fine for getting around a city, but they will not be useful for long trips. Little cars will go 450 kilometers before needing to stop for more gasoline (汽油).
If big cars are still used along with the small ones, two sets of roads will be needed in the future. Some roads will be used for the big, fast cars and other roads will be needed for the slower small ones.

Answer 1

一种新的小型汽车会替代今天的汽车，如果将来人人都驾驶这样的汽车，那么污染会变得更少。城市也会有更多的停车空间，街道也就不会那么拥挤。三辆车占的空间也不过现在寻常一辆车占的空间。
拥有一辆这样的小车开不需花费太多票子～开起来也十分安全，一个小时也不过行驶65千米。未来的这种车在城市兜兜还是蛮有用的，但不适用于长途行驶。这小车行驶450千米之后，恐怕就要停下来加多点油了。
如果大车和小车还一起实用，在未来就需要两条车道了。一些车道为大车、快车而使用。慢车就将使用其他车道了。
