Life in the 22nd century will be different from that in the 21st century, because many changes (变化) will take place. 1． 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 useful, and there will be at least one in every home. And computer studies will be one of the most important subjects at school.

People will work fewer hours than they did in the 21st century, and they will have more free time for sports, watching TV and shopping. 2． And more people will go to other countries for holidays.

3． 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 expensive. Maybe no one will eat it every day; instead they eat more vegetables and fruit. In this way, people will be healthier.

4． Robots will do dangerous and hard work. Because of this, many people will not have enough work to do. This will be a problem.
