地球是人类的朋友，我们只有一个地球。.地球是一个美丽的地方，有森林、河流、大海、山和田野，很多动植物生长在地球上；现今地球有很多污染：开车会污染空气；砍伐树木，很多动植物会失去它们家园；把垃圾倒入河流会污染水；
The earth is the friend of mankind, we have only one earth. The earth is a beautiful place, forests, rivers, sea,mountains and fields, many animals and plants growing in the earth; earth today have a lot of pollution: drive will pollute the air; cut down trees, many plants and animals will lose their homes; put the rubbish into the river water pollution;
我们应该保护地球。
We should protect the earth.
