We are now living in a common home. That is the earth. She provides us with enough food, enough water and enough living room. So we must do everything to protect her. There are lots of big or small, red or green, beautiful gardens around us .But there are still some other lands bare of grasses or trees on the earth. Some people may ask why not led all lands covered with trees, flowers and grasses? Why not prevent the lands from being desert? Why not prevent the air from being polluted? And why not prevent the earth from being poisoned? Yes! Our environment is being polluted faster than nature and man s efforts can prevent. Time is bring us more people, and more people will bring us more industry. So many trees will be cut down, and more large cities will be set up. Lots of waste material, in return, is produced and harms the environment. So some experts declare that the balance of nature is being destroyed. The survival of man is in danger. We feel really sad about it. What can we do to solve this problem? We must forbid cutting down trees and forbid killing animals and pouring waste water into rivers and so on. We ll never destroy the balance of nature. Let s get along well with all animals. Let the trees, flowers and grasses come back to our home. Because we have only one home --- the earth.
我们现在住在一个共同的家里。那就是地球。她给我们提供了足够的食物，足够的水和足够的起居室。所以我们必须尽一切努力保护她。我们周围有许多大大小小的、红绿相间的美丽花园，但还有一些土地上没有草和树。有些人可能会问，为什么不让所有的土地都长满树、花和草呢？为什么不阻止土地变成沙漠呢？为什么不防止空气被污染呢？为什么不阻止地球中毒呢？对！我们的环境被污染的速度比自然和人类的努力所能阻止的要快。时间会带给我们更多的人，更多的人会带给我们更多的工业。那么多的树木将被砍伐，更多的大城市将被建立。作为回报，大量的废料被生产出来并危害环境。所以一些专家宣称自然界的平衡正在被破坏。人类的生存正处于危险之中。我们对此感到很难过。我们能做些什么来解决这个问题？我们必须禁止砍伐树木，禁止捕杀动物，禁止向河流倾倒废水等。我们永远不会破坏自然的平衡。让我们和所有的动物和睦相处。让树，花和草回到我们的家。因为我们只有一个家——地球。
