Life in the 21st century will be different from life in the 20th century, because many changes will take place in the new century, but what will the changes be?

The population is growing fast. There will be more and more people in the world and most of them will live longer than before. Computers will be much smaller and more use?ful, and there will be at least one in every home. And computer studies will be one of the important subjects in school.

People will work fewer hours than they did in the 20th century, and they will have more free time for sports, watching TV and travelling. Travelling 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. Then there will be less room for cows and sheep, so meat will be more ex?pensive. Maybe no one will eat it every day, instead they eat more vegetables and fruit. Maybe people will be healthier.

Work in the future will be different, too. Dangerous and hard work will be done by robots(机器人). Because of this, many people will not have enough work to do. This will be a problem.
