在帮三翻译文章，大意是介绍自己，希望能和一家德国工厂建立合作关系。期间遇到很多专业的术语，只能一个词一个词的baidu和google了。
现在是元宵节那，外面炮声隆隆的，没想到北京人过节怎么这么能放炮。好多骑车也吱吱乱叫，被震的够呛。

水污染英语作文
pring is tht best season of the year. the weather gets warmer and warmer. my clas iamates and i took a one-day sightseeing around our city.the scene was pretty. but when we saw the rivers along our city, i felt very sorry, and thoughit a lot.
with the development of modern agriculture and industry, more and more waste water is being poured into rivers. it has caused serious pollution. the river is becoming so dirty that no living things can live in it. the river is giving off a terrible smell.
we make an urgent appeal that measures should be taken to cope with the situation. our government should start building various facilities such as sewage treatment!plant and encourage scientists to work out more and better ways to reduce the pollution of water.
water is tho source of our lives. it is very important to protect water.
春天是一年中最好的季节，天气变得越来越暖和。我和我的同学们进行了一次环城一日游，所到之处景宜人。但当我看到沿着城区流过的河流时，我感到很惋惜，想了很多。 随着现代工农业的发展，越来越多的污水排进河里，河水被严重污染。河水变得如此的肮脏以致于生物不能在里面生活。河水发出难闻的气味。
我们急切呼吁采取措施改变这种状况。政府应当建立各种设备，例如污水处理厂，并且鼓励科学家们想出更多更好的办法以减少水污染。
水是生命之源，保护水资源十分重要。
  my classmates and i had an outing this spring. we had a good time. but meanwhile i noticed that water pollution in our city was becoming more and more serious.
on our way, we could see women washing clothes in the river. litter was floating on the river. waste water produced by a chemical factory was being discharged into the river. we did not see any fish in the river. the fiver was not so clear as before. water quality was very bad. i am worried
about it because water is important to all living things. man can not live without water. i hope people pay more attention to this problem, especially the government. try to control the pollution of water as early as possible.
at last i would like to say, to protect water is to protect life.
今年春天，我和我的同学去春游，我们玩得都很高兴。但同时，我也注意到我们城市的水污染变得越来越严重了。
沿途我们看到许多妇女在河边洗衣，河面上漂着垃圾，一家化工厂正将废水排入河中。河中看不到一条鱼，河水也不像从前那样清澈了，水质很差。对此我深感担忧，因为水对于所有生物都非常重要。没有水人类将无法生存。我希望人们能多关注这个问题，特别是政府部门，争取及早解决水污染问题。
最后，我想说“保护水就是保护生命。”
the importance of water
hello,my name is cui xuerong,today im going to talk about the importance of water.water is very important for living things. without water there can be no life on earth. all animals and plants need water. man also needs water.
water is found atmosteverywhere. even in the driest part of the world there is some water in the air.
as we all have found out, water may be a solid, or a liquid or a gas.when it isa solid, it may be as hard as brick, when itis a liquid, you can pour it out of a container. when it is a gas, you cannot see or feel it.
