     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 useful, and there will be at least one in

 every home. And computer studies will be one of the most important subjects in schools.

     People will work fewer hours than they did in the 20th century, and they will have more free time for

 sports, watching TV and traveling. Traveling will be much cheaper and easier. And more people will go to

  other countries for holidays.

     There will be changes in our food, too. More land will be used for buildings, 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. 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).
