What kind of life will we live in the future? I think we won't use paper to write on, We can study on{#blank#}1{#/blank#} (计算机). And there won't be many cars and much {#blank#}2{#/blank#} (污染). Everyone will try their best to protect(保护) the{#blank#}3{#/blank#} (环境).

    The sea will be cleaner and the {#blank#}4{#/blank#} (天空) will be bluer. So the world will be better and better.

    And people will even have {#blank#}5{#/blank#} (机器人) in their homes. They can help with the housework. Of course, there are many robots working in {#blank#}6{#/blank#} (工厂) now. They do easy jobs over and over again. And they will never get {#blank#}7{#/blank#} (无聊的).

    People will be able to travel to other {#blank#}8{#/blank#} (行星) like the Mars for holidays. Maybe people will live on a {#blank#}9{#/blank#} (太空) station one day. However. some people {#blank#}10{#/blank#} (不赞同) on this. They think it is not safe for people to live on other planets.

    Almost every school has its rules. For example, don't be l{#blank#}1{#/blank#} for school; don't walk on the grass; don't p{#blank#}2{#/blank#} the flowers; keep the classrooms clean and tidy every day and so on. And in America, schools also have many rules for the students. Here are some American school rules.
