① 求空气污染的原因和解决办法的六分钟英语小短文
Nowadays, the air pollution is very serious. It not only does great harm to people’s health but also causes water and soil pollution. So we must pay much more attention to this. The causes to air pollution are various. First, our instry send out much waste and poisonous gases into the air without being dealt with. Second, when we cook, we burn many things which can proce harmful gas. This case can be seen everywhere, especially in the wide rural area. As we all know, the transportation, such as cars, planes, trucks and so on proce a large amount of waste gas. So we must take measures to rece the air pollution. First, the government must give severe punishment to those factories which send out poisonous gases without dealing with them. Second, when we cook, we should try to use some clean energy. We should plant much trees and grasses to clear the air. Only in this wan can we save our air and ourselves as well.If we do every we can ,the air pollutionwill be solved soon

Stop water and air pollution in China
Along with the rapid economic development in China, water and air pollution have become more and more severe. Everywhere we go, we can see rivers, lakes and even the sea are polluted and have become dark and dirty. Fish have died out and water is no long suitable as drinking water.At the same time, the air in every big city in China has, to some extent, been polluted by factories and cars on the road. Particularly, on rush hours everyday, it is hard to breathe for people who walk on the street if there is no wind or rain.
Shall let this situation go worse and worse? No, certainly not. So what shall we do to prevent people from polluting our water and air? I believe that on one hand, every local government should take quick and strict measures to stop those factories from polluting rivers and lakes any further. On the other hand, we should restrict the number of cars on the street, so that air in the city can be kept cleaner. Moreover

Win Competition of Environment Protection for Beijing
Although the 2008 Olympics are still three years away, another special competition has already started in Beijing. This time, the competitors are not the athletes from all over the world, but the people living in Beijing. The special competition is not held in a stadium, but in every street and every corner of Beijing. I suppose some of you may have already guessed what the special competition is. Yes, it is the competition of protecting our environment and creating a green Beijing for the 2008 Olympic Games.
Someone may ask who is our rival in this competition? The modern Los Angeles, the charming Sydney, or the historic Athens? No, none of them. The real rival is ourselves. It is our bad habits of neglecting to protect environment in our daily life.
Several years ago, I was very lucky to have an opportunity to live in the United States for about two years. I not only enjoyed the beautiful environment there, but also appreciated the American people's active way of protecting their environment. Now, whenever the environment protection is mentioned, a beautiful view of California will arise in my mind: white clouds flying across the blue sky, green grassplot sprinkled with colorful flowers and small animals playing happily among the trees.
I remember that at the beginning of my coming to America, I often went to my father's working place, the United States Geological Survey, to have fun. Each time I found a lot of people riding bicycles to their offices. Among the cyclists, an old man with white hair attracted my attention. Curiously, I asked my father," Why does the old man ride his bike to work every day? Doesn't he have enough money to buy a car?" Father laughed, "No, not because of money. Actually, he is one of the greatest scientists in the world. He can afford to buy a motorcade if he likes. He is just an environmentalist and usually doesn't drive unless going shopping, or in bad weather. In America, there are a lot of environmentalists, who actively protect their environment. For example, in Palo Alto city we are living now, there is even a bicycle-to-work day on May 19th every year to encourage people to decrease air pollution caused by cars".
Later, I also learnt another interesting fact of environment protection there. In some states of America, in order to decrease air pollution, save energy and rece traffic jams, state governments encourage people to take buses to work or to share a car among several people. They even set special "diamond lanes" in some main streets, which are only for the vehicles with 2 or more people.
The positive actions of American people and the effective measures the American government takes in environment protection fully won my respects and deeply affected my consciousness in environment protection.
When I was back in China, people often asked me: " What do you think of America?" I always bolt out:" Wonderful, especially the beautiful environment." Frankly speaking, after several years, the faces of my American teachers and friends have graally faded away from my mind, but the blue sky, green grass and lovely animals in California often arise in my mind, and became my dream of visiting there again.
The 2008 Olympics provide us with the opportunity to publicize and practise environment protection in Beijing. Is it possible for Beijing to Is it possible for Beijing to become as beautiful as California? The answer is "yes", but the dream needs every Beijing citizen's full support and active moves to accomplish.
From now on, if every student who is driven to school can take bus or ride bicycle to school once a week, if every car owner goes to work in a car pool once a week, we can make a difference. If everyone can actively protect the environment in our daily life, the blue sky, green grass and lovely animals in California will appear in Beijing.
Tiny streams can combine into a vast ocean, small trees can together be an immense forest. Beijing is often described as a beautiful and aged picture. If every Beijing citizen adds a trait of green on the picture, the whole Beijing will become an ocean of green. Let us unite together to win the competition of environment protection in Beijing, and present the world a big gold medal. That is "Green Beijing, Great Olympics "

打好环保比赛、创建绿色北京
尽管2008北京奥运会离我们还有3年之遥，但有一项规模宏大的特殊比赛已经拉开了序幕。这场比赛的参加者并非来自世界各国的体育选手，而是身处北京的每一位公民，比赛的场所就是我们身边的街区小巷。我想大家已经想到了我所说的这项特殊比赛，这就是"创建绿色北京、保护美好环境"。那么在这场环保大赛中，我们究竟要与谁一比高低？是繁华现代的洛杉矶、风光迷人的悉尼、还是古老神奇的雅典？都不是！比赛的对手就是我们自己，就是我们自身淡漠的环保意识。
几年前有幸在美国加州度过的一段时光，既让我享受了那里宜人的环境，更让我领略了当地人民高度的环保意识。每当说到城市环保，我的眼前总会浮现出加州那蔚蓝的天空、明媚的阳光、碧绿的草地以及嬉戏在树枝间的松鼠、彩蝶和百灵鸟。
记得刚到美国时，常去爸爸工作的美国地质调查局玩耍，每次均能看到许多人骑自行车上下班，而其中一位满头白发的骑车老人，引起了我的好奇。我问爸爸，"那个爷爷为什么总骑车上班，是不是没钱买车？"爸爸笑道："没钱买车？嘿，说出来吓死你，他可是世界上顶级的大科学家。要论钱，他可以买一个车队呢。" "那他咋不买车呢？骑车多累呀！" "他有车，但平时除非下雨或购物，一般不去开。在美国有许多人都是环保主义者，为了节约能源和减少汽车尾气对大气的污染，他们用实际行动倡导人们尽量少开车。而我们所居住的这座美国城市，还特别将每年的5月19日定成了'骑车上班日'，以支持和宣传这种有效的环保行为。"
后来，我还在经常的搭车出行中获知了他们的另一件环保趣事：在美国的许多州，政府为了鼓励大家多坐公交车或几人合用一辆车，以节省能源和缓解交通压力，在城市内一些主干道路上开辟有专门的'钻石车道'，只有乘坐了二人或二人以上的车辆才从此通过。美国人民这种自觉的环保意识和政府有效的环保措施使我从内心对他们充满了敬佩。并深刻地影响了我的环保理念。
回国后，常常有人问我："美国好吗？"我总会脱口而出："确实好！最好的是环境。"说句真心话，回国三、四年，美国那边同学和老师的面孔已经逐渐模糊，但加州那宜人的自然环境，却每每清晰地浮现在我的眼前，成为我最深的记忆和期盼故地重游的缘由，也成了我心目中北京环境的蓝图。2008奥运会为我们倡导和实施北京的环保提供了契机，北京能否有朝一日也拥有象加州那样美丽的环境？答案是肯定的。但需要我们以真正的环保之心和切实的环保行动去一步一步地实现。
从现在开始，如果每一位有车的朋友一星期可以少开一、两次车，每个让家长用车接送的同学一周能主动让家长少接送一两趟而改乘公车或骑自行车，我们就会有拥有更多的蓝天……。只要我们每一位北京市民都能够自觉的从身边的环保小事做起，加州的蓝天、白云和绿草地就会在北京安家，美国的松鼠、彩蝶和百灵鸟就会来北京落户。
涓涓细流可以汇成滔滔江海，片片绿叶能够造就莽莽森林。只要我们每一位北京市民都拿起手中的环保之笔，在我们所处的街头巷尾，为北京这幅美丽而古老的画卷添上自己的一抹绿色，就能使北京掩映在绿色的海洋中。让我们一起行动起来，用我们集体的力量来打赢这场环保之赛，向全世界展现一块最大的金牌，这就是"绿色北京、精彩奥运"。
⑤ 关于中国空气污染的英语作文
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 instrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is proced by burning fuels. The burning proces wastes, some of which remain in the air, causing air pollution.
Scientists are finding ways to stop air pollution especially in big instrial 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.

Air pollution is one of the most serious problems in the world today. People make the air dirty with machines. Machines proce gases and smoke. Badly polluted air can cause sickness and even death. We want to stop pollution, but we think it is a difficult problem to solve.
Most of our pollution is caused by things that people need. Automobiles and airplanes cause pollution. Factories cause air pollution, too. But they also provide jobs and procts for people. Every day thousands of automobiles and factories can add tons of pollution air. It is dangerous to people's health. It can damage the plants that provide us with food.
Nobody likes air pollution. Scientists and engineers try their best to develop automobiles and factories that proce less pollution. People can work together to persuade businessmen to be more concerned about the problem.
⑦ 有关空气污染的英语作文。最好中英文对照，三个减少空气污染的原因分别举例子。
给你两篇，一篇是专业的，另一篇是比较简单的
There are several main causes of air pollution, the vast majority of them can be attributed to man. This article will give you a definition of air pollution and list some of the top causes and how each one contributes to the contamination in the atmosphere.
Air pollution is the introction into the atmosphere of chemicals, particulates, and biological matter that cause harm to humans, other living organisms, or cause damage to the natural environment. Stratospheric ozone depletion(contributed to air pollution) has long been recognized as a threat to human health as well as to the Earth’s ecosystems. The Earth is capable of cleaning itself of a certain level of pollution, but man-made pollutant have become too numerous for the Earth’s natural mechanisms to remove. We are seeing the results of this overload in the form of acid rain, smog, and the variety of health problems that can be contributed to our environment.
One of the main causes of air pollution is manufacturing. This source of pollution spews particulate matter and chemicals into the atmosphere. The exhaust from a factory includes, sulfur oxides, nitrogen oxides, carbon monoxide and dioxide, as well as volatile organic compounds and particulates. There is not an area of the Earth’s atmosphere or an ecosystem that has not been altered by the long term effects of the pollution created by manufacturing. Strides have been made to filter the material coming from manufacturing plants, but it may take the Earth millenia to completely recover from the damage already done.
As the list of causes of air pollution goes this next offender is number one. The burning of fossil fuels is a part of the everyday life of every human on the planet. We burn fossil fuels in our cars, fossil fuel is burned to extract fossil fuel from the Earth, and fossil fuel is used to process fossil fuel into its indivial components. Every step of the way releases sulfur and nitrogen oxides, carbon monoxide, heavy metals, and particulates into the air. Each step in the process increases the number of asthma cases in the world, raises a person’s chance of having cancer, and increases the chance that your child will be born with congenital defects.
The Earth itself contributes to air pollution through volcanic eruptions, wildfires, and other natural process, but it is capable of recovering from those sources. As humans continue to instrialize with a dependence on fossil fuels, we continue to put our planet’s future in jeopardy and shorten the longevity of our species.
这是另一篇比较容易的
Air pollution is one of the virtual problem nowadays. There are many reasons of it but mostly it is caused by cars, growing cities, development of economy and instrialization.
Clean air consist of several gases. When some other gases or dangerous elements get into the clean air, pollution is inevitable. Ozone layer is affected too much by pollution and it will cause serious disturbances on the environment.
People are the main cause of pollution because the things that we use contain dangerous chemicals and they make atmosphere dirtier. Furthermore climate changes because of pollution.
Many substances involved in the things that people use, pollute the air seriously. For instance, cigarettes contain carbon monoxide. It occurs when wood or petrol are not burned. Another one is carbon dioxide and it emerges when we burn coal or wood. When these gases contact with atmosphere, ozone layer is destroyed.
The other one is lead and simply paint or batteries that we use in daily life contain lead but we should be careful since it may cause serious problems if it gets into our bodies.
Generally these gases come from factories but also there are dangerous materials in our houses. In order to keep ourselves from the possible effects of pollution we have to take precautions towards air pollution.
We can control ourselves and we should act carefully. So, for example, we should use public transportation, avoid spray cans. Besides, people mostly be careful regarding trees as they are sources of oxygen. Due to its importance we should keep them clean.
Environment and also air are so significant for all living beings. So people should take into account this issue and they should do whatever they can to keep our environment clean.
⑧ 大气污染资料（英文的）
pollution
The presence in the atmospheric environment of natural and artificial substances that affect human health or well-being, or the well-being of any other specific organism. Pragmatically, air pollution also applies to situations where contaminants impact structures and artifacts or esthetic sensibilities (such as visibility or smell). Most artificial impurities are injected into the atmosphere at or near the Earth's surface. The lower atmosphere (troposphere) cleanses itself of some of these pollutants in a few hours or days as the larger particles settle to the surface and soluble gases and particles encounter precipitation or are removed through contact with surface objects. Unfortunately, removal of some pollutants (for example, sulfates and nitrates) by precipitation and dry deposition results in acid deposition, which may cause serious environmental damage. Also, mixing of the pollutants into the upper atmosphere may dilute the concentrations near the Earth's surface, but can cause long-term changes in the chemistry of the upper atmosphere, including the ozone layer. See also Atmosphere; Troposphere.
Types of sources
Sources may be characterized in a number of ways. First, a distinction may be made between natural and anthropogenic sources. Another frequent classification is in terms of stationary (power plants, incinerators, instrial operations, and space heating) and moving (motor vehicles, ships, aircraft, and rockets) sources. Another classification describes sources as point (a single stack), line (a line of stacks), or area (city).
Different types of pollution are conveniently specified in various ways: gaseous, such as carbon monoxide, or particulate, such as smoke, pesticides, and aerosol sprays; inorganic, such as hydrogen fluoride, or organic, such as mercaptans; oxidizing substances, such as ozone, or recing substances, such as oxides of sulfur and oxide s of nitrogen; radioactive substances, such as iodine-131; inert substances, such as pollen or fly ash; or thermal pollution, such as the heat proced by nuclear power plants.
Air contaminants are proced in many ways and come from many sources; it is difficult to identify all the various procers. Also, for some pollutants such as carbon dioxide and methane, the natural emissions sometimes far exceed the anthropogenic emissions.
Both anthropogenic and natural emissions are variable from year to year, depending on fuel usage, instrial development, and climate. In some countries where pollution control regulations have been implemented, emissions have been significantly reced. For example, in the United States sulfur dioxide emissions dropped by about 30% between 1970 and 1992, and carbon monoxide (CO) emissions were cut by over 30% in the same period. However, in some developing countries emissions continually rise as more cars are put on the road and more instrial facilities and power plants are constructed. In dry regions, natural emissions of nitrogen oxides (NOx), carbon dioxide (CO2), and hydrocarbons can be greatly increased ring a season with high rainfall and above-average vegetation growth.
The anthropogenic component of most estimates of the methane budget is about two-thirds. Ruminant proction and emissions from rice paddies are regarded as anthropogenic because they result from human agricultural activities. The perturbations to carbon dioxide since the instrial revolution are also principally the result of human activities. These emissions have not yet equilibrated with the rest of the carbon cycle and so have had a profound effect on atmospheric levels, even though emissions from fossil fuel combustion are dwarfed by natural emissions.
Effects
The major concern with air pollution relates to its effects on humans. Since most people spend most of their time indoors, there has been increased interest in air-pollution concentrations in homes, workplaces, and shopping areas. Much of the early information on health effects came from occupational health studies completed prior to the implementation of general air-quality standards.
Air pollution principally injures the respiratory system, and health effects can be studied through three approaches, clinical, epidemiological, and toxicological. Clinical studies use human subjects in controlled laboratory conditions, epidemiological studies assess human subjects (health records) in real-world conditions, and toxicological studies are concted on animals or simple cellular systems. Of course, epidemiological studies are the most closely related to actual conditions, but they are the most difficult to interpret because of the lack of control and the subsequent problems with statistical analysis. Another difficulty arises because of differences in response among different people. For example, elderly asthmatics are likely to be more strongly affected by sulfur dioxide than the teenage members of a hiking club. See also Epidemiology.
Damage to vegetation by air pollution is of many kinds. Sulfur dioxide may damage field crops such as alfalfa and trees such as pines, especially ring the growing season (Fig. 1). Both hydrogen fluoride (HF) and nitrogen dioxide (NO2) in high concentrations have been shown to be harmful to citrus trees and ornamental plants, which are of economic, importance in central Florida. Ozone and ethylene are other contaminants that cause damage to certain kinds of vegetation.
Air pollution can affect the dynamics of the atmosphere through changes in longwave and shortwave radiation processes. Particles can absorb or reflect incoming short-wave solar radiation, keeping it from the Earth's surface ring the day. Greenhouse gases can absorb long-wave radiation emitted by the Earth's surface and atmosphere.
Carbon dioxide, methane, fluorocarbons, nitrous oxides, ozone, and water vapor are important greenhouse gases. These represent a class of gases that selectively absorb long-wave radiation. This effect warms the temperature of the Earth's atmosphere and surface higher than would be found in the absence of an atmosphere (the greenhouse effect). Because the amount of greenhouse gases in the atmosphere is rising, there is a possibility that the temperature of the atmosphere will graally rise, possibly resulting in a general warming of the global climate over a time period of several generations. See also Greenhouse effect.
Researchers are also concerned with pollution of the stratosphere (10–50 km or 6–30 mi above the Earth's surface) by aircraft and by broad surface sources. The stratosphere is important, because it contains the ozone layer, which absorbs part of the Sun's short-wave radiation and keeps it from reaching the surface. If the ozone layer is significantly depleted, an increase in skin cancer in humans is expected. Each 1% loss of ozone is estimated to increase the skin cancer rate 3–6%. See also Stratosphere.
Visibility is reced as concentrations of aerosols or particles increase. The particles do not just affect visibility by themselves but also act as condensation nuclei for cloud or haze formation. In each of the three serious air-pollution episodes discussed above, smog (smoke and fog) were present with greatly reced visibility.
Chemistry
Air pollution can be divided into primary and secondary compounds, where primary pollutants are emitted directly from sources (for example, carbon monoxide, sulfur dioxide) and secondary pollutants are proced by chemical reactions between other pollutants and atmospheric gases and particles (for example, sulfates, ozone). Most of the chemical transformations are best described as oxidation processes. In many cases these secondary pollutants can have significant environmental effects, such as acid rain and smog.
Smog is the best-known example of secondary pollutants formed by photochemical processes, as a result of primary emissions of nitric oxide (NO) and reactive hydrocarbons from anthropogenic sources such as transportation and instry as well as natural sources. Energy from the Sun causes the formation of nitrogen dioxide, ozone (O3), and peroxyacetalnitrate, which cause eye irritation and plant damage.
It has been shown that when emissions of sulfur dioxide and nitrogen oxide from tall power plant and other instrial stacks are carried over great distances and combined with emissions from other areas, acidic compounds can be formed by complex chemical reactions. In the absence of anthropogenic pollution sources, the average pH of rain is around 5.6 (slightly acidic). In the eastern United States, acid rain with a pH less than 5.0 has been measured and consists of about 65% dilute sulfuric acid, 30% dilute nitric acid, and 5% other acids.

⑨ 关于空气污染的英语作文
Air pollution
Air pollution comes from factories, power stations and cars. Chemicals in the smoke from power stations cause a lot of damage. They can travel hundreds of miles in the wind before falling to the ground in the rain. But this "chemical rain" graally destroys trees in the forests and kills fish in the lakes. In Germany, over 50% of the country＇s trees had been damaged by the year 1986.
Time and time again there are serious accidents that pollute the air. In 1986 there was a bad accident at a nuclear power station in Russia. A cloud of radiation crossed the whole of Europe. It is said that 125,000 people died in Russia as a result of illnesses caused by this accident.
In 1984 there was a serious accident at a factory in India and a cloud of dangerous gas covered the town of Bhopal. Over 2,500 people were killed that night, and hundreds of thousands of people were injured. Many of the injured lost their sight.
空气污染
空气污染来自工厂、电站和汽车。电站发出的烟雾中所含的化学物质造成很大的破坏。这些化学物质可以随风飘走几百英里，然后才随雨水降落地面。但是这种“化学雨”逐渐摧毁森林里的树木，杀死湖泊中的鱼。在德国，到1986年止，全国已经有过半数的树木被摧残。
空气被污染的严重事故不时地在发生。1986年俄罗斯一座核电站发生过一起严重事故。一团带有辐射的尘埃穿越了整个欧洲。据说，在俄罗斯有125 000人由于这次事故引起的疾病而死亡。
1984年印度一家工厂发生了一起严重事故，一团有危险的气体笼罩着博帕尔市，当晚就有2500多人死亡，有成千上万人受伤，受伤者中有许多人双目失明。
