Life in the future 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 lessons will be one of the most important subjects in schools then.
People will work _______ hours than they do now and they will have _____ 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.
