A kind of little car may someday take the place of today's big ones.If people drive such cars in the future, there will be less pollution in the air. There will be more space for parking in cities. The streets will be less crowded.And driving will be safer as these little cars can go only 65 km per hour.The future cars will be fine for getting round a city, but they will not be useful for long trips.Little cars will go 200km, before needing to stop for more gas.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 slow and small ones.It's said that three such little cars fit in the space now needed for one car the usual size.
一種小型汽車某一天可能會取代今天的大型汽車。如果將來人們開這樣的車，空氣中的污染會更少，城市會有更多的地方停車，街道也會不那么擁擠。駕駛也會變得更安全，因為這些小車每小時只能行駛65公里。未來汽車會適合繞城行駛，但是不適合長途行駛。小汽車在需要加油前能夠行駛200公里。如果大車和小車同時使用的話，將來將需要兩種道路。一些道路是快車專用，其他的則給慢車和小車專用。有人說，三個這樣的小車才需要一輛現(xiàn)在一般汽車大小的空間。
