Yesterday and Today Life in the twenty-first century will be different from life today. Between then and now many changes will take place, 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 travel. 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 fruit and vegetables. Maybe people will be healthier. Work in the future will be different, too. Dangerous and hard work will be done by robots. Because of this, many people will not have enough work to do. This will be a problem. 小题1:In the next century people don’t’ have to ______________.
