水是疾病传播的重要媒介。水污染对人体的危害是多方面的,当人体受到化学有毒物质污染后,会引起人的急性或慢性中毒。如果汞、镉、砷、氰化物、农药、多氯联苯等侵入人体后,都可以引起人体中毒。污水中有害物质在土壤中积累并被植物吸收,加上不适当地使用化学农药,会使大量残留的有害物质散布到田间,继而污染粮食、蔬菜、烟叶等农副产品,引起疾病。另外,水污染还会引起水媒介的传染病,如人畜粪便等生物性污染,可以引起细菌性肠道传染病,如伤寒、痢疾、霍乱等。Water is an important medium for the spread of the disease.The harm of water pollution on the human body are many,when the human body by the toxic chemical pollution,cause acute or chronic poisoning people.

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
