let's be friends of the Earth 用一般現在時 本人初二水平- - 70左右
1.Who are friends of the Earth?
2.What are we doing to the Earth?
3.How can we be friends of the Earth?

解答：

We are living on the earth,so the earth is our home.We should be good friends of the earth.But some people always do something bad to the earth.For example,some forests are cut down so the land become desert.And many animals die out.Some people pollute the river or the lake,so the drinking water.is becoming less and less.
We should protect the earth.We should plant trees every year.We shouldn't throw waste into the river or lake.In this way,we can be good friends of the earth.
