Write a passage on how to make your school greener and give reasons.
Use the list you have made in Activity 7 to help you. Use because, so and so that.
Don’t throw bottles away because it is better to recycle them.
新课讲解
Possible answer:
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!
新课讲解
Reuse
Many people like disposable cutlery（一次性餐具）because they don’t have to wash up. But it isn’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, 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!
