英语翻译
Every year more and more plants and animals disappear never to be seen again.Strangely,it is the most intelligent but most thoughtless animal that is causing most of the problems—man.Nature is very carefully balanced and if this balance is disturbed,animals can disappear very fast.Every day,thousands of species of animals draw closer to extinction.There are countless number of species which may become extinct before they are even discovered.
In many lakes the fish are dying.Fishermen are worried because every year there are fewer fish and some lakes have no fish at all.Scientists are beginning to get worried too.What is killing the fish?
The problem is acid rain.Acid rain is a kind of air pollution.It is caused by factories that burn coal or oil or gas.These factories send smoke high into the air.The wind often carries the smoke far from the factories.Some of the harmful substances in the smoke may come down with the rain hundreds of miles away.
The rain in many places isn't natural and clean any more.It's full of acid chemicals.When it falls in lakes,it changes them too.The lakes become more acidic.Acid water is like vinegar or lemon juice.It hurts when it gets in your eyes.It also kills the plants and animals that usually live in lake water.That is why the fish are dying in lakes.
But dead fish may be just the beginning of the problem.Scientists are finding other effects of acid rain.In some large areas trees are dying.Not just one tree here and there,but whole forests.At first scientists couldn't understand why.There were no bugs or diseases in these trees.The weather was not dry.But now they think that the rain was the cause.Acid rain is making the earth more acidic in these areas.Some kinds of trees cannot live in the soil that is very acidic.
Now scientists are also beginning to study the effects of acid rain on larger animals.For example,they believe that some deer in Poland are less healthy because of acid rain.If deer are hurt by the rain,what about people?This is the question many people are beginning to ask.No one knows the answer yet.But it is an important question for us all.

每年有越来越多的植物和动物消失,永远不会再见到过.奇怪的是,这是最聪明的,但最盲目的动物,是造成最多的问题-男子.大自然是非常小心平衡,如果这种平衡受到破坏,动物可以消失很快.每天都有数以千计的动物物种接近灭绝.还有无数的物种可能绝种,才发现连.在许多湖泊鱼类死亡.渔民们非常担心,因为每年都有较少的鱼类和部分湖泊没有鱼的一切.科学家们开始了解太担心.什么是杀鱼?问题是酸雨.酸雨是一种空气污染.它是由工厂燃烧煤或石油或天然气.这些工厂发出浓烟高排放到空气中.风往往带有烟雾远离工厂.一些有害物质的浓烟可能回落在雨中数百英里.雨水在很多地方是不自然的,干净了.它充分的酸性化学物.当瀑布湖泊,它改变了他们.湖泊更加酸性.酸性水像醋或柠檬汁.心痛,当我们获得您的眼睛.它也可杀死植物和动物,一般生活在湖泊水体.这就是为什么鱼死湖.但死鱼可能只是问题的开始.科学家们正在寻找其它影响酸雨.在一些大面积树木死亡.不只是一棵树躺在那里,而且是整个森林.当初科学家们无法理解为何.有任何错误或疾病而这些树木.天气不干燥.但现在他们认为下雨的原因.酸雨是使地球更加酸性在这些地区.有些种类的树木,不能生活在土壤中,很酸.现在科学家们又开始研究了酸雨对较大的动物.举例来说,他们认为有些鹿波兰不太健康,因为酸雨造成的.如果鹿是伤害了不少雨,什么人?这个问题是许多人都开始问.没有人知道答案.但是,这是一个重要的问题,值得我们学习.
