1.求一篇关于中国空气污染的英文小短文,在线等,急
中国是世界上最大的煤炭生产国和消费国。
大约 78% 的电力、60% 的民用商品能源以及 70% 的化工原料均靠煤。煤的直接燃烧是中国最重要的人为空气污染源。
中国摩托车的生产占世界第一，汽车生产占世界第 11 位。尽管用车的数量远远低于发达国家，但国产车每公里排放的空气污染物却是欧洲车的 3 到 5 倍。
因为中国城市的道路系统设施低劣，城区的车速比发达国家低得多。道路面积只占上海市总面积的 3.6%，而东京则占总面积的 14.1%。
中国汽车数目将在未来十五年内跃升四倍，所以融合最新技术的智能汽车将成为解决中国空气污染和能源问题的关键。根据中国国家环境保护总局资料，到二零零六年，在道路上行驶的汽车预计将增加到三千三百万辆，到二零二零年更将跳升至一亿三千一百万辆，由此可能引发的空气污染和能源短缺问题实在不容忽视。

Production caused by human activities, water body pollution. Industrial water pollution is the most serious cause. If industrial wastewater containing pollutants it more complex components, not only in water purification difficult, but also more difficult to deal with. Industrial wastewater, industrial pollution is the most important cause of water pollution is the cause. It accounted for the bulk of industrial emissions of pollutants. Pollutants in the industrial wastewater plant variety and diversity because, even similar factories, production processes, they do not contain the quality and quantity of pollutants. In addition to the industrial wastewater discharged directly into water bodies from pollution, solid waste and emissions will pollution to the water body. 。

First of all agricultural pollution is due to land reclamation projects farming land surface or loose in the soil and topography, rainfall is not stable, a natural water flows, increased water suspended objects. Another important reason is that in recent years, pesticides, fertilizers usage growing, and the use of pesticides and chemical fertilizers or absorb only a small amount, the vast majority of the remaining residue in the soil and floating in the atmosphere, through rain, through the dirt surface runoff into surface water and infiltration of surface water forming pollution. For the urban population is concentrated in urban pollution, urban sewage, garbage and water pollution caused by emissions from. Urban pollution to the water body pollution mainly sewage, it is the daily life of a sewage cooks, including the kitchen, wash room, bathroom and toilet discharge of sewage. Urban areas of the world only a year from industrial waste water and living up to 500 kilometers on, and each several times and even a few drops of sewage pollution will be 10 times the water body. For sewage main measures are : 1 : financial, administrative, legal safeguards (1) financial support is essential Obviously, financial support is one of the important conditions for pollution control, no funds all management measures can not be implemented. (2) government support for urban water pollution control is a wide range, not only involving residents, but also relates to field personnel, involving troops system involving minorities, but also involves the interests of the right holder. Therefore, water sector, the problem could not be solved alone, even coupled with the environmental sector, the forces remain unable to pale. Needs strong government support, the city government also needs the support of the central government. Without a strong government support, many of the mandatory measures will be difficult to work. (3) pollution control laws and regulations is, the common law requires compliance with the criteria and should develop local laws to protect the urban water environment for water management law, according to the law, which will be easier to do something. 人类生产活动造成的水体污染中。工业引起的水体污染最严重。
如工业废水，它含污染物多，成分复杂，不仅在水中不易净化，而且处理也比较困难。 工业废水，是工业污染引起水体污染的最重要的原因。
它占工业排出的污染物的大部分。工业废水所含的污染物因工厂种类不同而千差万别，即使是同类工厂，生产过程不同，其所含污染物的质和量也不一样。
工业除了排出的废水直接注入水体引起污染外，固体废物和废气也会污染水体。
农业污染首先是由于耕作或开荒使土地表面疏松，在土壤和地形还未稳定时降雨，大量泥沙流入水中，增加水中的悬浮物。 还有一个重要原因是近年来农药、化肥的使用量日益增多，而使用的农药和化肥只有少量附着或被吸收，其余绝大部分残留在土壤和漂浮在大气中，通过降雨，经过地表径流的冲刷进入地表水和渗入地表水形成污染。
城市污染源是因城市人口集中，城市生活污水、垃圾和废气引起水体污染造成的。城市污染源对水体的污染主要是生活污水，它是人们日常生活中产生的各种污水的混合液，其中包括厨房、洗涤房、浴室和厕所排出的污水。
世界上仅城市地区一年排出的工业和生活废水就多达500立方公里，而每一滴污水将污染数倍乃至数十倍的水体。 对于污水采取的措施主要有： 1： 资金、行政、法律保障措施 （1） 资金支持是必不可少的条件 显然，资金支持是污染治理重要的条件之一，没有资金，一切治理措施就无法实施。
（2） 政府的支持是后盾 城市水系污染治理涉及面很广，不但涉及到居民，还涉及到外地人员，涉及到部队系统，涉及到少数民族，也会涉及到权利持有者的利益。因此，单靠水利部门是无法解决问题的，即使再加上环保部门，力量依然是苍白无力的。
需要市政府的强力支持，市政府也需要中央政府的支持。没有一个强大政府的支持，许多强制性措施就难以行得通。
（3）污染治理需要法。

关于家乡的大气污染 About The Air Pollution In My Hometown
In my hometown, the air is polluted seriously. However, in recent years, the pollution gets from bad to worse, because of the increasing number of private cars. Especially during the rush hours, too many private vehicles move slowly on narrow roads, emitting a large amount of waste gas. Moreover, the poisonous gas sent by the nearby factories is also one of the main causes of pollution. Therefore, it’s demanded that immediate and effective measures must be taken to restrict private cars and public transportation must be developed to the largest extent. Besides, we should use renewable and clean energy recourses.

AIR POLLUTION Sandstorms and the dust and gases from volcanoes pollute the earth’s atmosphere naturally. But the most serious kind of air pollution comes from people. Factories, power stations, and rehicles exhausts[1] pump harmful gases into the air, contributing to global warming, causing acid rain[2], and destroying the ozone layer. On a much smaller scale, air pollution causes all sorts of breathing problems. There are no simple solutions to air pollution, but people could reduce air pollution by saving energy and reducing harmful emissions from vehicle exhausts and power stations. When a volcano erupts, dust is blasted[3] high above the troposphere and may take weeks to be carried around the weather zone, so cannot be washed out of the air by rain. It will eventually fall to the earth after a few years. Air pollution is at its worst over big cities where millions of people live, work, and travel about in cars, buses, and trucks. Factory chimmeys can be fitted with devices to cut down[4] air pollution, but this is expensive. If better pubic transport and cycle lanes were available in towns and cities, people would be less likely to use their cars, reducing the overall amount of pollution. Smoking cigarettes adds to the general levels of air pollution as well as damaging our health. Cigarette smoke contains chemicals that can cause cancer, a gas which stops oxygen being taken into the blood and a substance called nicotine, which raises blood pressure and makes the heart beat faster. No-smoking areas cut down on this pollution and save non-smokers breathing in other people’s cigarette smoke. 空气污染 沙暴和火山爆发喷出的尘埃和有毒气体自然而然地对地球大气造成的污染，然而最严重的空气污染却来自人类。
工厂、火力发电站和车辆将有害废气排放到空气中，是造成全球气候变暖，出现酸雨，破坏臭氧层的罪魁祸首。就更小的范围来看，空气污染会引发各种呼吸道疾病。
没有解决空气污染的简单办法，但人们可以通过节约能源、减少车辆和火力发电站的有害气体排放来达到降低污染的目的。 火山爆发时，尘埃被高高喷射入对流层以上的空间，需要几个星期才飘浮移至气象层，因而雨水无法将其从大气中冲走。
几年之后，尘埃将最终漂落在地球上。 好几百万人在城市里工作、生活，还以轿车、公共汽车和卡车为交通工具，因而这种百万人口的城市空气污染最为严重。
工厂烟囱可以安装滤清装置以减少空气污染，但成本昂贵。如能改善城镇公共交通，并设置自行车车道，人们就不再会热衷于使用自家汽车，从而达到全面减少污染的目的。
吸烟不仅对健康有害，而且增加空气污染程度。香烟雾含有多种有害物质：不仅有致癌化学物质、有某种能阻止氧气进入血液的气体，还有引起血压增高、心速加快的被称为尼古丁的物质。
设立禁烟区有助于减少污染，并能使不吸烟者免受被动吸烟之害。
7.描述污染的英语作文,可以是空气污染、水污染、土地污染、噪音污染
Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited. Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive. We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products are still put into rivers. We know that if the population continues to rise at the present rate, in a few years, there won’t be enough food.What can we do to solve these problems? If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept. Our natural resources will last longer if we learn to recycie them. The world population will not rise so quickly if people use modern methods of birth control. Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.。

Air pollution is one of the major problems of the modern world. A great deal of energy is needed to run the factories of modern industrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution. Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material. Also, engineers try to design and locate new power plants to do minimum damage to the environment. However, it may be that we still have a long way to go before we have a “clean” world. Nearly all of the countries are trying hard to prevent and control air pollution. There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution.翻译：空气污染是当今世界几大主要问题之一。
现代工厂的运作需要极大的能源。汽车，火车，飞机和公交车也需要能源。
几乎所有的能量都是由燃料的燃烧产生。燃烧的过程中产生废物，其中有些就残留在空气中，引起了空气污染。
后面的就不翻译了，额。 楼主看看吧，好就给分吧。

空气是多种气体的混合物。
它的恒定组成部分为氧、氮和氩、氖、氦、氪、氙等稀有气体，可变组成部分为二氧化碳和水蒸气，它们在空气中的含量随地球上的位置和温度不同在很小限度的范围内会微有变动。至于空气中的不定组成部分，则随不同地区变化而有不同，例如，靠近冶金工厂的地方会含有二氧化硫，靠近氯碱工厂的地方会含有氯等等。
此外空气中还有微量的氢、臭氧、氧化二氮、甲烷以及或多或少的尘埃。 实验证明，空气中恒定组成部分的含量百分比，在离地面100km高度以内几乎是不变的。
以体积含量计，氧约占20.95%，氮约占78.09%，氩约占0.932%， 空气中主要成分氮和氧相对恒定的原因是自然界各种变化相互补偿的结果。 动植物的呼吸、物质的燃烧、动植物的腐烂、钢铁的锈蚀都需要耗用大量的氧气，但是绿色植物在日光下也要进行光合作用，即吸入空气中的二氧化碳，同时放出氧气。
实验证明植物放出氧气的总量比它呼吸时需要氧的量多20倍左右。这就是氧气量保持相对平衡的原因。
植物生长需要氮元素。氮元素的来源就是空气中的氮气。
天然固氮主要是靠闪电将氮气氧化成一氧化氮，一氧化氮进一步氧化成二氧化氮，在雨水中溶解形成亚硝酸和硝酸。进入土壤中转变为亚硝酸盐和硝酸盐。
据估计，通过这种途径，每年可以从大气中固定约4000万吨的氮，还有少量氮是通过豆科植物的根瘤菌固定的；人工固氮的主要途径是用氮气合成氨。而被固定的氮，又可以被一类叫反硝化细菌的微生物分解成氮气返回大气。
就这样，在自然界又完成了另一个循环——氮循环，使得大气中氮的含量也几乎保持恒定。
