答案 Cars in the Future As big cars cause many problems,/such as pollution, shortage of parking space, crowded traffic,/scientists are now trying to design some small cars that may some day replace today’s big automobiles./If more people begin to drive such cars in the future,/there will be less air pollution./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/that is 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 as these cars can only go 60 kilometers per hour./ The cars of the future will be fine for driving around the city./However, they will not be suitable for long trips,/because these cars by petrol can only go 450 kilometers/before needing to stop for refueling./
