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!
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. Turn off the lights when you do not need them. Before you buy something new, think whether it is really necessary because maybe the old one is just as good!
Reading and vocabulary
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. It is better to use china cups and cloth bags because they can be used many times.
Reading and vocabulary
Recycle
Recycle means “change things into something else to be reused”. Although it takes energy to change things into something else, it is better than throwing things away or burning them.
change…into…
“把…变成…”
