【考点】议论文；环境保护．

【答案】As we know，the environment around us is getting worse and worse.Some factories produce terrible gas.Rivers are heavily polluted.
    As students，we should do something for the environment.First，we'd better reuse the old textbooks and use both sides of the paper.Second，we should remember to turn off the lights when we leave the classroom.What's more，we can ride a bike or walk to school instead of taking a car.Besides，it's a good idea to use china cups instead of paper cups.Finally，we should plant more trees to make our environment greener.
    It is important to protect the environment because we have only one earth.If we try our best，we can make the world a better place to live in.
