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(chē)某一天可能會(huì)取代今天的大型汽車(chē)。如果將來(lái)人們開(kāi)這樣的車(chē)，空氣中的污染會(huì)更少，城市會(huì)有更多的地方停車(chē)，街道也會(huì)不那么擁擠。駕駛也會(huì)變得更安全，因?yàn)檫@些小車(chē)每小時(shí)只能行駛65公里。未來(lái)汽車(chē)會(huì)適合繞城行駛，但是不適合長(zhǎng)途行駛。小汽車(chē)在需要加油前能夠行駛200公里。如果大車(chē)和小車(chē)同時(shí)使用的話，將來(lái)將需要兩種道路。一些道路是快車(chē)專用，其他的則給慢車(chē)和小車(chē)專用。有人說(shuō)，三個(gè)這樣的小車(chē)才需要一輛現(xiàn)在一般汽車(chē)大小的空間。
