The home of the future won’t be completely different and we will be living in houses and flats just as we do today．But people will want to shape their homes to match their dreams．No two homes will be the same．People will be able to buy “house kits” containing a basic house structure, with movable walls, doors and windows．They will put together the different parts to create the home they want．

Many jobs that we do today will disappear, others will still exist but will change and new jobs will be created. Skilled workers such as builders, gardeners and electricians won’t disappear because machines can’t replace them. Teachers will still exist because students need human contact. But they will be using modern technology in class more and students will be working more from home. The medical technology revolution and space travel will create new jobs which we can only imagine today．

Space holidays will develop in the future, but these holidays won’t be for everyone because they won’t be cheap. Short space trips will develop first, then space hotels will orbit the earth where it will be possible to have a longer vacation. By the end of the next century, there will be holiday centres on the moon with leisure facilities for families．

Paper won’t exist in the future. Instead, there will be e-paper which people will be able to use over and over again. This will develop in order to save natural resources. E-newspapers and e-magazines will replace traditional newspapers and magazines and we will download information and news articles from the Internet every day onto our reuseable paper．

The laws of physics tell us that the earth is going to disappear some time in the future．This isn’t going to happen tomorrow but scientists predict that it will happen in five billion years when our sun explodes (爆炸)．We will have to explore the universe and find another home. At some point in the distant future, either we stay on the earth and die with it, or we leave and move to another planet. There won’t be any other choice.
