段落
1.With the beach,we can''t enjoy the sea.With the sun,the isn''t beautiful,either.Without the environment,we also lose home.
没有了海滩，我们享受不到大海的乐趣。没有了太阳，月亮也不再美丽。没有了环境，我们也就失去了家园。
2.Environmental problems are becoming more and more serious all over the world. For example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. Trees on the hills have been cut down and waste water is being poured continuously into rivers.Furthermore, wherever we go today, we can find rubbish carelessly disposed. Pollution is, in fact, threatening our existence.
全世界的环境问题变得越来越严重。例如汽车污染的空气影响了人们的呼吸，工厂释放污染的气体，山上的树木被砍伐，污水不断被排人河里。另外，无论我们走到哪里，到处可见随意丢弃的垃圾。事实上，污染正威胁我们的生存。
3.The earth is our home and we have the duty to take care of it for ourselves and for our later generations. Fortunately, more and more people have realized these problems. Measures have been taken to cope with these problems by the government. Laws have been passed to stop pollution. I hope the problem will be solved in the near future and our home will become better and better.
地球是我们的家园，我们有责任为我们自己和我们的后代去照顾好它。庆幸的是，愈来愈多的人们已经意识到这些问题。政府已经采取了很多措施去解决这些问题，法律已被通过以制止污染。我希望这些问题在不远的将来能得到解决，我们的家园变得越来越好。
4.Environmental problems are becoming more and more serious all over the world. With the development of industry and agriculture, cars make GREat noises and give off poisonous gas. Trees on the hills have been cut down,and waste water is being poured continuously into rivers. Furthermore,wherever we go today, we can find rubbish carelessly disposed. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to man''s existence.
全世界的环境问题在变得越来越严重。随着工农业的发展，汽车制造噪音、排放毒气，山上的树木被砍伐，污水不断被排入河里。另外，无论我们走到哪里，到处可见随意丢弃的垃圾。整个地球生态平衡正在改变，环境的巨大破坏已带来负面影响，甚至对人类生存带来巨大威胁。
5.We must face the situation that exists and take actions to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the pub!ic must receive the education about the hazard of pollution and so on. We hope that all these measures will be effective and bring back a healthful environment.
我们必须面对现实，采取行动解决环境问题。例如必须通过新的法律严格控制工业污染问题，大众必须接受污染危害的教育等。我们希望这些措施的有效实施能带给我们一个健康的环境。
