育才学习网1.一篇关于水污染的英语作文
ll fish and make water unsafe for drinking. In a word, polluted water is a big problem to everyone.
As you know, people depend on water to live on. They should be involved in finding a solution to this problem. I think, certain counter measures need to be taken as soon as possible. To begin with, the governments of all countries are supposed to formulate rules and regulations to deal with the pollution problem. In addition, factories in towns and cities must be prohibited from draining waste liquids into rivers before they are totally treated and purified. I feel if they violate relevant rules or laws, they should be fined heavily. Certainly, there are some other cures which are worth adopting.
As far as future prospect is concerned, I am sure that good results will be achieved in this respect. Rivers which used to be contaminated by industrial wastes will be cleaned and fish which could not live there a few years ago will be again. To conclude, it seems obvious that tomorrow will be better and brighter only if everyone does his part and tries hard to seek solutions for its control.
If any further comment on the issue is required, please don't hesitate to write to me.

我和我的同学们进行了一次环城一日游，所到之处景色宜人。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 I'm 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. Although about 70 percent of the earth's surface is covered with water, But with the rapid development of agriculture and industry, more and more water is needed. Therefore, water is becoming scarce in many places. What's more, a lot of rivers and lakes are beginning polluted by the waste watcr from factories. Fish can't live in them any longer. At the same time, thc waste water does great harm to people's health. In order to make rivers and lakes clean and prevent water from being polluted,we must do something to stop all sorts of pollution. 翻译： 大家好，我是崔学荣，今天我要和大家谈一谈水的重要性。 水对生物很重要，没有水，地球上就没有生命。
所有的动植物都需要水。人类也需要水。
水几乎无处不在。即使在世界上最干燥的地方，空气中也有水。
水，正如你所了解的，有固态、液态和气态。当它是固态时，它可以像砖一样硬；当它是液态时，你可以将它从容器中倒出；当它是气态时，你看不见或感觉不到它。
虽然地球表面70%是水覆盖着，但是随着工农业的迅速发展，水的需要量越来越大。因此，许多地方缺水。
而且，许多河流湖泊被工厂排放的污水所污染，鱼不能生存。同时，废水给人们的健康带来极大的危害。
为了保持河流湖泊清洁，防止水污染，我们必须采取措施，阻止各种污染。

River PollutionIt seems that almost every day there is another story about pollution of one form or another, in the food we eat, the water we drink and the air we breathe. Very often our own actions lead to that pollution and in many cases we can do something about it. These notes explain how you can investigate pollution and advise on positive action to improve our rivers.Over 97% of all the water on Earth is salty and most of the remaining 3% is frozen in the polar ice-caps. The atmosphere, rivers, lakes and underground stores hold less than 1% of all the fresh water and this tiny amount has to provide the fresh water needed to support the Earth's population. It is estimated that, with the expected increase in population, there will be a 200% increase in world water needs by the year 2000. Fresh water is a precious resource and the increasing pollution of our rivers and lakes is a cause for alarm.Most fresh water pollution is caused by the addition of organic material which is mainly sewage but can be food waste or farm effluent. Bacteria and other micro-organisms feed on organic matter and large populations quickly develop using up much of the oxygen dissolved in the water. Normally oxygen is present in high quantities but even a small drop in the level can have a harmful effect on the river animals. Animals can be listed according to their ability to tolerate low levels of oxygen. In the following list animals which indicate a high level of dissolved oxygen are at the beginning while animals indicating a low level of oxygen are at the end: stone-fly nymphs, mayfly nymphs, freshwater shrimps, freshwater hog lice, blood worms, tubifex worms and rat-tailed maggots. If you see dead fish floating on the river or notice that the water is discoloured and smelly any one of the following forms of pollution may be the cause:fertilisersindustrial wasteoilwarm water All incidents of river pollution should be reported to the Pollution Control officer at the Water Authority giving as much detail as you can: date, time, exact place and precisely what you saw. a) FertilisersIf large amounts of fertiliser or farm waste drain into a river the concentration of nitrate and phosphate in the water increases considerably. Algae use these substances to grow and multiply rapidly turning the water green. This massive growth of algae, called eutrophication, leads to pollution. When the algae die they are broken down by the action of the bacteria which quickly multiply, using up all the oxygen in the water which leads to the death of many animals.b) Industrial Waste Chemical waste products from industrial processes are sometimes accidentally discharged into rivers. Examples of such pollutants include cyanide, zinc, lead, copper, cadmin and mercury. These substances may enter the water in such high concentrations that fish and other animals are killed immediately. Sometimes the pollutants enter a food chain and accumulate until they reach toxic levels, eventually killing birds, fish and mammals.Occasionally poisonous substances are deliberately dumped into rivers and if you see this so-called 'fly-tipping' going on take the registration number of the vehicle and if possible the name of the firm. Report the matter to the police who will then take it further.c) Oil PollutionIf oil enters a slow-moving river it forms a rainbow-coloured film over the entire surface preventing oxygen from entering the water. On larger stretches of water the oil contaminates the feathers of water birds and when they preen the oil enters the gut and kills them. d) Warm WaterIndustry often uses water for cooling processes, sometimes discharging large quantities of warm water back into rivers. Raising the temperature of the water lowers the level of dissolved oxygen and upsets the balance of life in the water.WarningWhen sampling polluted water simple precautions must be taken to avoid getting infected. Packed lunches should be eaten before visiting the river or after washing carefully in a supply of clean water. Rubber gloves should be worn and all the equipment should be thoroughly washed at the end of the investigation.。
