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.

During our two months on the road，Bennett and I had a really 　36　 experience with a good，honest 　37　 and some helpful mechanics（机修师）.

We were driving east on Highway 10 when our “check engine” light came on. We limped（拐）off a（n）　38　 into Las Cruces. We had a real car 　39　.Bennett nursed the car into a local garage. By the time the car was missing（熄火）, it was shaking all over so 　40　.This was the 　41　 time to arrive at a garage―late Friday afternoon. Service adviser Scott was busy 　42　 paper work and customers as we 　43　 our problems.　44　 he was already “ten cars behind”，he told us to pull the car into the garage.

Lincoln，who we later 　45　 was one of the top motor technicians，took 　46　 of our car repairing. He and Scott and some other mechanics stayed several hours after closing，　47　 the car.

Early the next morning(the shop was officially closed on Saturdays)，Lincoln finally located the 　48　and fixed it easily within only 　49　.

Later Scott 　50　 out to us that it was our attitude that helped. “You didn’t come into the place demanding this or that. You showed an 51　of our problems on a busy Friday afternoon. Customer’s attitude means a lot.” He was right in some way，customers should show 　52　 and understanding to people who 　53　 them.　54　 people are extremely busy，they can find a way to at least try and help when they are met with politeness.

The pleasant experience I had shows that 　55　 for other people can always help.
