閲讀下面短文, 根據其內客完成後面各項任務。

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 當你不需要的時候就把燈關上。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.
