Today,pollution has become a serious problem to us.It means that the air,seas,rivers and land are polluted by waste or poisonous things.It does harm not only to human beings but also to animals (It does harm to animals,as well as human beings.).
We cannot have fresh air because many factories have the poisonous smoke sent into the air.Beautiful parks are made dirty by plastic tins and bags.Fish die from the polluted water.It is said that strange diseases have appeared in some places because of pollution.
I hope scientists can find ways to solve the serious problem.We are looking forward to seeing the clear sky,clean rivers and beautiful parks again.

亲爱的大卫,
我很高兴你将要来北京学习中文.中文十分有用,许多外国人现在都在学习它.对于你来说学习中文很难,因为它很不同于英语.你不得不尽可能的记住中文词语.做一些阅读和写作（练习）也是重要的.你可以通过看电视和听收音机来练习你的听力.你最好用中文同他人交流（Do your best to talk with people in Chinese.这句有错误.）.你可以不仅从书中学习英语,还可以从你周围的人来学习英语.如果你还有任何问题,请来问我.我相信你将会中文学得很好.
希望在不久和在北京看见你.
你的（朋友）,
王明
今天,污染已经变为一个对于我们来说很严重的问题.这意味着空气、海洋、河流以及陆地被污染物或有毒物污染.这不仅仅对人类造成伤害,也对动物造成伤害.（这伤害动物也伤害人类.）
我们不能拥有新鲜的空气,因为许多工厂将污染的烟雾送到空气中.美丽的公园被塑料罐和袋弄脏.鱼在污水中死去.据报道,因为污染,一些奇怪的疾病在一些地区被发现.
我希望科学可以找到方法来解决这些严着的问题.我们期待再一次看见晴朗的天空,干净的河流和美丽的公园.
