　　The City of the Future

　　What will the city of the future look like①？ No one knows for sure②， and making predictions③ is a risky④ business. But one thing is certain - they are going to get bigger before they get smaller. In the future, care⑤ for the environment will become very important ⑥as earth's natural resources⑦ run out⑧. We will use lots of recycled materials⑨， such as⑩ plastic, aluminium, steel, glass, wood and paper, and we will waste fewer natural resources. We will also have to rely more on⑪ alternative⑫ energy, such as solar⑬ and wind power. All this seems certain, but there are plenty of⑭ things about city life in the future which are not certain.

　　To find out what young people think about the future of urban⑮ life⑯， a teacher at a university in Texas in the United States asked his students to think how they would run⑰ a city of 50,000 people in the year 2025. Here are some of the ideas they had：

　　Garbage ships　To get rid of⑱ garbage problems⑲， the city will load⑳ huge spaceships with waste materials and send them towards\s\up1(21(21) the sun, preventing landfill\s\up1(22(22) and environmental problems\s\up1(23(23).

　　Batman Nets　Police will arrest\s\up1(24(24) criminals\s\up1(25(25) by firing\s\up1(26(26) nets instead of\s\up1(27(27) guns.

　　Forget smoking　No smoking will be allowed\s\up1(28(28) within a future city's limits\s\up1(29(29). Smoking will be possible only outside cities, and outdoors\s\up1(30(30) .

　　Forget the malls　In the future all shopping will be done online\s\up1(31(31)， and catalogues\s\up1(32(32) will have voice commands\s\up1(33(33) to place orders\s\up1(34(34).
