P99
Help Make a Green School!
We can do many things to make our school green. Remember the three most important words: reduce, reuse and recycle!
Reduce
Many people waste paper because paper is cheap. But we should use less paper so that we can save trees. Make sure you write or print on both sides of the paper so that nothing is wasted. This simple tip will cut your paper usage in half!
A Possible version:
Reuse
Many people like disposable cutlery(餐具) because they don't have to wash up. But these things aren't green. Bring your own chopsticks from home and reuse them. Don't use disposable cups or plates, either.
Recycle
We all eat and drink at school every day, so there are plenty of wrappers(包装纸), bottles and cans to dispose of. But don't just throw your bottles, wrappers and cans in the rubbish bin - support the school's recycling programme! Put paper, plastic, glass and metal in the recycling bins.
Follow these steps and we'll all have a green school!

As we know, our school is a place where we study together. We need a healthy environment. As a result, it’s important for us to make a green school.
However, there are some bad behaviours to the environment at school. For example, some people don’t turn off the lights when they are leaving.
In order to make a green school, we should remember three words daily: reduce, reuse, and recycle. First, we should use less electricity and water . Please turn off them after using. Second, it’s better to reuse something useable, such as books and paper. Because it helps save many trees. What’s more, it’s necessary to divide rubbish and recycle.
In a word, let’s make a green school from now on and do it from ourselves. We hope our school will be greener and greener.
How to make our school green
As we know, our school is a place where we study together. We need a healthy environment. Now our school is becoming more and more beautiful. We must do something to make our school green.
If possible, we should walk or ride a bike instead of taking a taxi or a car, because cars and taxies make a lot of pollution. We can't throw rubbish away. Don't waste water or electricity and try to use fewer school things, we can reduce waste. If we plant more trees and flowers around our school, it will be better and better.
If everyone protects our school environment, it will become better and better.
