未来汽车的发展趋势是由大变小，小汽车的好处有多少？
Small cars
Here are two cars that may some day take the place of today's big automobiles.If everyone drives such a car in
the future，there will be less pollution in the air.There will be more parking space in the 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 per hour.
