Can you make animals work for us? Some scientists think that one day we can teach animals to do a lot of things for people. In a film shown on TV, you may see elephants, monkeys, tigers or some other animals are always given a little food to eat after they have done something. Scientists say that people can teach many different animals to do some of the easy work if they know they will get something to eat. We all know elephants can carry large logs(圆木)，and dogs can look after houses. And we even teach animals to work in factories. In America, for example, people have used apes to help make cars and scientists think that those large monkeys may drive trains one day. Now people are trying to get them to do the same thing that man does.

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.
