A kind of little cars may take the place of today’s big ones many years later. If everyone drives such cars in the future, there will be less pollution in the air. There will also be more space for parking in cities, and the streets will be less crowded.
The little cars of the future will cost less. Driving will be safer, too, since these little cars can go only 65 kilometers an hour. The cars of the future will be fine for going around a city, but they will not be useful for a long way. Little cars will go 450 kilometers before they need to stop for more gasoline (汽油). If big cars are still used with the small ones, two kinds of roads will be needed in the future. Some roads will be needed for the big, faster cars and other roads will be needed for the small, slower ones.

Life in the future will be different from life today. Between then and now many changes will happen. But what will the changes be?

The population is growing fast. There will be many people in the world and most of them will live longer than people live now.

 Computers will be much smaller and more useful，and there will be at least one in every home. And computer studies will be one of the important subjects in schools then. People will work fewer hours than they do now and they will have more free time for sports，watching TV and traveling. Traveling will be much cheaper and easier. And many more people will go to other countries for holidays.

 There will be changes in our food，too. More land will be used for building new towns and houses for all the people. Then there will be less room for cows and sheep，so meat will be more expensive. Maybe no one will eat it every day. Instead，they will eat more fruits and vegetables. Maybe people will be healthier. Work in the future will be different，too. Robots will do dangerous and hard work. Because of this，many people will not have enough work to do. This will be a problem.
