1. (2020·聊城) 阅读下面短文, 根据其内客完成后面各项任务。

    We all need a healthy environment, but we produce waste every day, and it is harmful to our environment. Repeat these three words daily: reduce, reuse and recycle.

    Reduce

    Reduce means "use less". Do not waste things. It saves money and causes less pollution. Do not order more food than you can finish. 当你不需要的时候就把灯关上。Before you buy something new, think whether it is really necessary because maybe the old one is just as good!

    Reuse

    Reuse means "use again". Use things for as long as possible. Look after them so that they will last. Repair them if possible. Do not throw them away and buy new ones. Do not use paper cups or paper bags.

    Recycle

    Recycle means "change things into something else to be reused". We throw tons of rubbish away each year, and we have to make a change. Divide your rubbish into plastic, glass, paper and rubber. Develop a recycling policy for the whole community. Buy products such as recycled paper to help save trees.
