有关空气污染的作文英文作文【实用19篇】

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.

我们生活的地球正遭受着严重的空气污染。工厂排放的废气、燃烧的垃圾、汽车的尾气等都是污染大气的祸源。它们时刻侵袭着我们的呼吸道和肺，使呼吸系统的发病率逐年上升。

The earth on which we live is to suffer from serious air pollution. The exhaust gas from the factory, the burning of waste, car exhaust and other pollution in the atmosphere are the source of trouble. The time of the invasion of the respiratory tract and lung, the incidence of respiratory rate increased year by year.

当空气轻微污染时，人体吸入的空气可以由鼻腔里的鼻毛除去部分灰尘，再由鼻腔里的黏液和各类支气管里的黏液将灰尘粘连住。气管和支气管内的纤毛有几千万根，它们每秒约摆动12次，像“清洁工”一样从下向上推扫呼吸道里的黏液，直至咽喉部，再通过咳嗽咳出体外。

When the air is polluted slightly, inhaled air can be part of the dust removal by nasal cavity in the nose, the nasal mucus in the bronchial mucus and the dust adhesion. Tracheal and bronchial cilia in tens of millions of their root, about 12 times per second to swing, like a "cleaner" from the bottom up sweep mucus in the respiratory tract, and throat, cough up through in vitro.

当空气严重污染时，呼吸道的净化作用将降低，甚至完全丧失。在这种情况下，呼吸道和肺易受病菌的侵袭而患各种疾病。

When the air is seriously polluted, the purification effect of respiratory tract will be reduced, and even lost completely. In this case, respiratory tract and lung is vulnerable to the invasion of bacteria and diseases.

由于种种原因，空气污染还在加剧。如果不能解决空气污染的问题，恐怕真有一天，人类只能带着口罩生活。

Due to various reasons, the air pollution is getting worse. If you can not solve the problem of air pollution, I am afraid it one day, humans can only live with a mask.

it is a very common phenomenon for us when we go shopping ,we will buy what we need in daily life toghter with many free plastic bags ,which we are inclined to discard casually.it is an intresting and beautifull landscapes to see many corlorfull plastic bags flying in the sky especially when there is a strong wind.and we call these plastic bags white pollution.

as we all know,the white pollution is besoming more and more serious nowadays. though we know its bad effects,still we find it difficult to refuse them,as they are very convenient for us.for instance,if we set a plastic bag into a bowl when we eat our foods,we will feel it easy to wash.however we ignore its bad effects.so,i think,we should keep a careful eye on them to keep our healthy and have a beautiful environment.

空气污染不管是对我们还是对植物危害都很大，为什么这么说?这是我通过一次研究发现的，至于是什么研究，就听我慢慢跟大家说。

在庭园里种些花草，不仅能美化我们的家，还能净化我们四周的空气，让我们呼吸的空气更清新。因此有人说，一个具有一定规模的庭园就像一个不停工作的天然“氧吧”，能提供我们所需的清新空气。但近几天我发现我家的天然“氧吧”“罢工”了，每天清早我到院子里，再也呼吸不到以前那种清新的空气了。这是怎么回事呢?是什么令到我家的天然“氧吧”停止工作呢?我下定决心，一定要把那个“凶手”揪出来!

针对上述事件，我查阅了大量资料，综合我对花草、树叶的连日观察，发现嫌疑最大的是近日车辆的频繁来往，造成了严重的空气污染，加上附近的一些食店排放出来的油烟因近日风势不强，得不到有效的散解，被花草、树叶过量地吸收，造成叶片表面气孔被尘粒堵塞，以至它们不能“工作”。我咨询了自然老师，老师认为这种可能性很高，让我回家去试验一下。于是我回去采了一些花草样本，把它们栽在室内，定期让它们照射阳光，浇水次数加密，几天后，和其他的比较一下，发现经我“悉心照顾”的那些花草比外面的生长得好多了。根据我的实验结果，我把每天浇水的次数加密到每天3次，经过我一个多星期“苦心经营”，“天然氧吧”终于又恢复了正常的工作，每天为我们提供着清新的空气。

综合以上所述，我得出了结论：“天然氧吧”的停止工作，是因为周围空气污染的日趋严重，使花草过量地吸收了空气中的一氧化碳、碳氢化合物、氮氧化物以及空气中的悬浮粒子，以至花草、树叶中用于进行光合作用的气孔被堵塞，机能超荷，停止工作。我终于把这个“凶手”揪了出来!

你看，这就是空气污染的危害。空气污染其实伤害的不仅仅是我们自己，也伤害了地球上的许许多多的生物，还有我们的地球母亲……让我们一起行动起来，减少空气污染，一起保护我们的生存环境吧!

空气污染是空气中某些物质的含量超过正常含量时，形成危害动、植物，影响其生存的现象。大气中C0、NH3、SO2、H2S、Cl2、03和N02等物质的正常含量均在百万分之一以下，对动、植物没有明显的不良影响。但19世纪以来，由于工业和交通运输的发展，那些物质大量排入大气，使空气污染日趋严重，影响到动、植物生命活动乃至人体健康。

污染物的来源，有的来自自然界（如火山喷出的烟灰），有的来自人类活动，其中工业、交通运输产生的废气是主要的污染源。空气污染可分为气体污染物和气溶胶状污染物两大类。气体污染物包括SO2，、03，、氮的氧化物以及碳氢化合物等；气溶胶污染物包括固体粒子（粉尘、烟尘气）和液体粒子（烟雾、雾气）两类。直接向空气中排放的污染物质，叫一次污染物。空气与污染物之间相互作用，产生反应，或空气中光化学反应引起的污染物变质所产生的新污染物，叫二次染物。

空气污染物种类很多，其中对农业威胁较大的约有十多种，如SO2、 HF、C12和光化学烟雾等。 气象条件对空气污染物的影响，水平风速和对流层高度是影响大气稀释空气污染物能力的两个气象要素。当农田上空主导风向来自污染源时，农田容易受有害气体的危害；风力强弱则影响空气污染物的扩散速度、污染物在空气中的浓度与平均风速成反比；通常午后湍流强，空气处于不稳定状态时，有利于扩散。夜间晴朗无风，近地面逆温层可使污染物在地面上停滞积聚，加剧空气污染的程度。另外，在准静止的高气压系统中，由于下沉逆温阻止下层排放的污染物扩散到大气上层，可形成近几百米厚的污染层。各国多次发生的严重空气污染事件大都是在低逆温层、风速小和无雨的气象条件出现几天之后形成的。

空气中一些污染物例，如SO2和悬浮于空气中的农药颗粒等，经雨水淋溶落到地面，又可污染土壤和植株。污染物对植物的危害，一般是通过气孔进入植物组织，干扰酶的作用，阻碍代谢机能，有的有毒物质在体内还可进一步分解或参与合成过程，产生新的有害物质，侵害细胞组织，抑制光合作用，使生长受阻、产量降低、品质变劣。其危害分为急性、慢性和不可见危害等。高浓度污染物造成急性伤害，引起产量显著下降，低浓度污染物，在长时间作用下，造成慢性危害，一般症状不明显。不可见危害只造成生理上的障碍，一般没有症状。

植物受空气污染危害的程度，主要受下列因素影响：污染物浓度和植物接触它的时间；植物本身的构造和所处的发育期以及环境条件的影响。如充足的光照，适宜的温度、良好的供水和空气湿润，较高的C02浓度等，都能导致叶片气孔开放，易受污染危害。 植物对大气的净化功能。不少植物具有一种以酶作催化剂的潜在解毒力，能够分解一些有毒物质，或形成一些大分子络合物，暂时可以降低毒性。1公顷森林，每年可吸滞灰尘30多吨，1公顷柳杉林，每年可吸收700多公斤S02，柑桔树的叶子可吸收储存硫达1％，青杨和桑树具有较强的吸收铅尘的能力，加拿大杨、银杏、榆树、梧桐、桉树等都是较好的“天然吸尘器”。草坪的吸附粉尘能力比裸露地面大几十倍。因此环境科学的任务之一，是要充分发挥植物净化大气的作用。选择吸收污染能力强的植物，扩大造林绿化面积，根据污染源位置、污染物汇集区的地形地势、风向和污染气体的季节分配，统一考虑构成一种包围式或隔离式的林带，使含尘气流在移动中途被树林吸收。另方面要研究采取控制或减少排放污染物的措施，以保证大气质量符合规定的标准。

有人说我是看不见摸不着的，也有人说我是地球的面纱，其实啊，我的名字大家非常熟悉——叫空气。我住在地球的最外面，我把地球轻轻地抱在怀里，与你们形影不离。

在广漠的宇宙中，我们的家庭可算是历史悠久的大家庭。我们推选出氧气、氨、氮、碳这三位成员作为家族中的核心，千百年来，我们在宇宙中默默无闻地生活。

说起我的岁数，可是你们长者中的长者了，若要我说出来，恩——少说也有十亿年了。

我算不上高尚伟大，但对地球上的生灵，我可以自豪地说：“我是无愧的。”我给了鲜花娇艳的姿态，我给了呱呱坠地的婴儿顽强的生命力……总之地球的生灵都要靠我，它的生命都是我给予的。早晨，当太阳女神初升之时，阳光透过我射进千家万户，生灵们呼吸着我，人们向我点头微笑……就这样，过了好多年。

我是地球上赖以生存的物质，俗话说：“远亲不如近邻”，因而人类对我非常地友好。但近几年来，人们的生活水平提高了，工业生产越来越发达了，却忽视了我，他们认为我是无足轻重的，使纯洁的我受到了污染。大约在两百年前，一些工业的废气排放出来，它们混杂在我的中间，天然的“过滤器”森林也被人们大批大批的砍伐掉了，鸟儿们无处安家。什么粉尘、烟灰全都寄托在我的身上，我好象成了天然的垃圾箱。人们呼吸了我而发生疾病，这使我万分痛苦，但人们却把“凶手”的帽子戴在我头上，什么害人精了。地球上的生灵请你们听听我的哀诉。

蓝天上笼罩了尘烟，小河里的水不再清澈见底了，工厂里排放出的废气张牙舞爪地向我扑来。天长日久，你们呼吸着不干净的我，生出了各种疾病，它们时时威胁着你们的健康，虽然“环保”工作人员做了不少环保工作，但我需要更多的人来保护我……

有人说，当世界上最后一只老虎在孤独中寻求配偶，最后一只雄鹰从天空坠向大地，最后一只鸟儿发出悲惨的鸣叫时，人类也就失去了自己的未来。这真是警世之言!

我希望我的自述能在地球上得到正确的回答，希望你们能帮助我摘掉“凶手”的帽子，保护你们赖以生存的环境。同学们，行动起来吧，做个环保小卫士!

1.There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.

To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

2.We can’t live without water, but now the water was polluted. It is the biggest problem. It influences our daily life. So we should find a way to solve this problem. Water is important resources. In our daily life, we often leave the tap on after cleaning hands. Sometimes we often drop litter in the river. So the water was polluted by us. I think we could use a bottle of water two or three times. We have to turn off the tap after cleaning hands.

Let’s try to form a good habit and save things around us. Let’s do it from now on!

Fish can’t live without water. Plants can’t live without water. People can’t live without water, either. As you can see, the water is very important to us. But now drinking water is leand less. The water was polluted seriously.

So we would act quickly in order to save the water, But what must we do nowI think we can plant trees, clean the banks of the river, water the plants by using used water. Turn off the shower while we are washing hair. And we shouldn’t drop litter into the river and so on.

It’s our duty to try our best to protect and save water. And don’t forget that if we don’t save water, the last drop of water will be our tear

Water is very important to us. We can’t live without water. But the drinking water is leand less. Because we waste a lot of water in our daily life. And some of us often throw rubbish into the rivers. So the rivers are polluted seriously.

It’s our duty to save water, we must do something to save water. For example, we shouldn’t pour waste water into the rivers and we should pick up litter around us.

If we don’t save water, the last drop of water will be our tear

大家都知道我们应该减少空气污染，但是很多人都只是嘴上说说，根本不去实践!你们知道空气污染的危害吗，你们知道如果不减少空气污染我们将要面临的是怎样的未来吗?

我的家乡——大连，是座美丽的城市。听爸爸说，以前的大连是个环境优美，空气清新的城市，空气中到处弥漫着海洋的味道，夏季的雨后，经常能看到美丽的彩虹如七彩桥一般挂在天边。我在家里看到过很多爸爸小时候的生活照片，在照片的背景中，我看到天空万里无云，马路上很少有各式各样的机动车，那时人们的交通工具主要就是靠公共汽车，环境确实比现在好多了。

现在家乡的车辆增多了，每天都有成千上万辆汽车行驶在马路上，这些汽车排放的尾气，不仅破坏了环境，同时也危害了人们的身体健康。我听广播说，汽车排放出的尾气使我们的城市变暖了，而且这些气体悬浮在城市上空很难消散，汽车尾气中还有大量的一氧化碳和二氧化碳，这些气体都是对人体有伤害的，如果被人们吸到体内，就会引起肺部的很多疾病呢。怪不得每天早上我上学的时候，天空中总是灰蒙蒙的一片，很难看到早上初升的太阳，雨后的天空中也没有彩虹，湛蓝深远的天空消失不见了，就连叽叽喳喳的小鸟也不愿意来到这样的地方，只有在儿歌中才有“太阳当空照，花儿对我笑，小鸟说……”的景象。

你知道吗，大连她在哭泣，她哭人们这样伤害她，破坏她，把她原本美丽的面貌变成了这样丑陋。我建议有车的家庭要减少车辆的使用，尽量步行或坐公交车，这样才能让我们的城市空气更清新。

我们大家都应该清楚知道空气污染的危害，然后赶紧行动起来，保护我们生存的环境，让空气污染不要伤害我们的家园!保护我们的家，从你我做起，从现在做起，从身边的小事赶紧做起!

Pollution is harmful to human beings. Polluted water causes many kinds of diseases such as diarrhea, enteritis, etc. And sometimes these diseases even take man’s life. Dirty air or air-borne garbage causes stinging eyes and running nose. Pollutants are destructive. They cause runs in nylon stockings and crack rubber tires and they eat away at stone and rust iron.

Measures have been taken to control pollution. In recent years, legislative steps have been introduced to control pollution. Rivers are being cleaned. Air is purified, and pollutants are being trapped before they are poured out of chimneys.

However, pollution problems have not been completely solved. Pesticides are widely used almost everywhere. They pollute soil, water and food. They have the power to make our streams fishless and our gardens and woodlands silent and birdless. Some factories are still using air as a dumping place for wastes. Some lakes are still dirty. Quite a few chimneys are still pouring smoke into air and noise pollution remains serious.

white pollution refers to plastic pollution. it is a new member of pollution family, but it grows fast. unrecyclable plastic lunch boxes line along railroads. plastic shopping bags dance in the wind. when leaders are busy mapping out blueprints for the future, one colour white from white pollution becomes their headache.

everything in the life circle deserves its place on earth. if we continue using plastic lunch boxes, shopping bags and other unrecyclable plastic productsmwhat would happen ⅱ one day they might bury us in an ocean of white rubbishg then the earthmour common home, would be a dustbin.

to prevent this nightmare from coming true, governments need to work closely with each other and back up their verbal commitment by actions. however, it is not enough only to ask what governments can do to get rid of white pollution, we must ask ourselves what we as individuals can do to colour the earth green instead of white.

how to save environment? i think we should do the followings: first, it’s best to ride a bike to school, don’t take a bus or a taxi. second, i will remember to turn off the lights when i leave the classroom. third, in my free time, i will collect the empty bottles and waste paper for recycling. the fourth idea is turning off the shower when i ‘m not using it. fifth, it is imporment to save water and money. also, i won’t spend too much money on expensive things. last, we had better not cut down the trees, we have to take care of the trees . i’ll try my best to save the energy, i hope i can do something for our country.

the environmental protection is the most major problem which in the modern life the humanity faces. must solve this problem must start from foundation. first, must massively propagandize, enhances peoples consciousness with understanding, strengthens the environmental protection consciousness. next, must carry on waste recovery use, reduces to forest-trees felling. also must strengthen to white pollution processing, little uses the plastic product. finally, must make improvement to clean aspect. causes the citys appearance to be neater. for earths tomorrow, we must start from the now diligently, will want the well local constable to protect the environment. to this us proposes as follows suggests: implementation trash classification packed in bags. like this not only can reduce the environmental sanitation workers work load, but also can even better basically arrive makes use of waste, to reduce the pollution, saves the resources.

Pollution is becoming more and more serious all over the world. As is shown in the cartoon, two cars are giving off waste gas and three people are trying to avoid breathing in the poisonous gas by masking their face with their hands. The poisonous gas sent off by factories, domestic appliances and automobiles has made the air unhealthy for people to breathe.

There is no denying that automobiles are indications of civilization, progress and development; nevertheless , automobiles cause the serious problem of air pollution. Scientists have warned that unless effective measures are taken, the problem of pollution will eventually get out of hand. Actually, people are showing a real concern over the problem. For example, there is an increasingly loud voice from the public for firm action against pollution from automobiles.

Indeed, the earth is our home and we have the duty to take care of it for ourselves and for our descendants. In my opinion, we should work out concrete solutions to the problem of pollution from poisonous gas given off by automobiles. For example, the automobiles should be equipped with a device which can dispose of waste gas so as to prevent it from polluting air. Only in this way can we really solve the problem of air pollution caused by automobiles.

污染变得越来越严重的世界各地。这幅漫画所示,两辆车散发废气和三个人正试图避免吸入有毒气体通过屏蔽自己的脸。工厂的有毒气体罚下,家用电器和汽车污染的空气影响了人们的呼吸。

不可否认,汽车文明的迹象,进步和发展;然而,汽车造成空气污染的严重问题。科学家们警告说,除非采取有效措施,污染的问题最终会失控。实际上,人们显示出真正的担忧的问题。例如,有一个公共的越来越大声对汽车污染公司行动。

事实上,地球是我们的家园,我们有责任照顾它为我们自己和我们的后代。在我看来,我们应该制定具体的解决问题的有毒气体污染的汽车。例如,汽车应该配备一个设备可以处理废气,以防止污染空气。只有用这种方法我们才能真正解决由汽车引起的空气污染的问题。

周六上午，我和爸爸妈妈一起骑车感受一下濮阳市的空气质量。虽然天气寒冷，但我也感觉不到冷，因为我要做一次小小的空气调查员。

一路上我们有说有笑，当走到黄河路西段时，一股难闻的气味扑鼻而来。我便问爸爸：“爸爸，这是什么气味呀，这么臭。”爸爸对我们说：“这里是我市的化工厂区，化工厂产生的废气气味。”

爸爸妈妈又带我来到马夹河边，看到河水的颜色发黑，并有一阵阵的恶臭，我问爸爸：这是为什么呢?爸爸给我讲：这是因为化工厂的污水和家庭的废水排向河流的缘故。

现在的空气污染太严重了，化工厂产生的废气，家庭的废水不经过处理直接排向空中和河流，汽车、摩托车等机动车数量迅速增加，尾气排放量加大。由此造成严重的空气污染。

为了缓解空气污染，请大家从身边的小事做起，不要乱扔垃圾，不要在野外烧火，尽量不要用尾气排放量高的汽车……相信有了大家的支持，空气污染造成的危害一定会消失!

As we all know, Beijing is facing the air pollution, a kind of environment pollution. Now Beijing is also famous of hazy weather, which is harmful to people’s health because of PM2.5 and PM10.

Why is our capital suffering the hazy weatherIn my view, Beijing is a center of economy, culture and politics, so she has a heavy traffic. As a result, there are a lot of cars here, then the exhaust of them become a part of reason of the air pollution. Besides, in order to have a good economy development, there are many factories around Beijing, the exhaust of the factories become another part of reason of the air pollution. The most import, our country is a developing one, and do not have enough ability to solve the pollution well while focusing on developing, just like UK was called The City of Fog before.

Now, Beijing has taken a lot of actions to deal with the hazy weather. Firstly, setting up the Bicycle exclusive channel, people are

encouraged to ride but not to drive, in this way, the exhaust of cars is decline. Secondly, many factories are forced to move to Hebei Provence, thus, they can continue to make a contribution to Beijing’s economy development and the air pollution is controlled. Finally, the buses and subway have a lower price than other cities, so that people prefer to go on work by bus or subway. And the limit line caused by tail number is effect, too.

I persist that the air pollution of Beijing can be controlled someday later.

Although some citys air quality is improving, but it is estimated that the number of deaths due to air pollution each year up to 358000 people.[5] according to the self assessment, air quality in the recorded data of 338 cities, two-thirds is considered contaminated, two-thirds of which was rated as moderate or severe pollution.Related to air pollution in China, breathing and heart disease is the top killer.Thirty percent for acid rain place.The Chinese governments environmental regulations are thought to have 20 years behind the United States, 20 to 30 yearsbehind that in Europe.And because of car usage increases, a true problem isworsening.

Draw lessons from the Beijing Olympic Games and Shanghai world expo and the guangzhou Asian games air quality guarantee of successful experience, promote the pearl river delta regional environmental cooperation, the implementation of regional air pollution defense measures from spreading.Host during the universiade held in shenzhen air pollution index is less than 30, the air quality is superior, the successful completion of the "green universiade" air quality security tasks.

北京空气重度污染高达五级

雾霾是近几年来比较常见的空气环境污染现象，它的出现也让人们加大了对空气质量的检测和改善工作的展开。

根据预测，本轮的重污染天气过程从2号开始一直持续到4号夜间，其中，今明两天空气最差，预计将达五级重度污染。2号，北京市发布了空气重污染橙色预警以来，北京市各相关部门分别落实应急措施，并加大了对污染源排放执法检查和应急减排措施督查力度。

为确保应急措施落实到位，环保部门加大对固定污染源、移动污染源排放执法力度，截至目前，共出动执法人员1030余人次，检查施工工地、企业排放等点位1100多个;在一些水泥搅拌站记者看到，相关企业已停工停产，水泥搅拌车成排停放在厂区内并都贴上了封条，同时，按照应急预案的要求，4S店里的喷涂车间也停止了使用。

此外，通过路检、遥测、入户和进京口检测，共检查机动车3.77万辆次，处罚尾气超标车辆50辆，劝返外埠进京超标车88辆。

与此同时，北京市住建部门还开展了应急措施落实专项检查，截至目前，共检查工程942项，其中违规工地101项;城市管理部门已出动清扫保洁作业人员27123人次，作业车辆3689车次，检查人员1026人次，对重点道路加大清扫保洁强度，减少道路扬尘污染。

从目前的整体情况来看，针对本轮空气重污染橙色预警，北京市各区、各相关部门应对响应及时，整体情况良好，但仍存在个别露天焚烧等违规情况，已交相关部门处理。

语文迷网站提醒您：雾霾的组成十分复杂，大小有数百种颗粒物，这些颗粒物通过人体呼吸，进入呼吸道，会引发气管炎、哮喘等呼吸道疾病。特别要提醒有相关疾病的人群，要注意多加防范，减少外出。

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" gradually destroys trees in the forests and kills fish in the lakes. In Germany, over 50% of the countrys 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.

空气污染是现代世界的主要问题之一。在现代化工业国家中，办工厂需要大量的能量。汽车、火车、飞机和公共汽车需要能量，几乎所有的能量都是由燃烧燃料产生的。燃烧产生的废物，其中一些留在空气中，造成空气污染。科学家们正在寻找阻止空气污染的方法，特别是在大工业区和人口稠密的城市。他们正在研究发电的新方法，这种方法对环境的损害较小。与此同时，许多发电厂正在现代化，以减少污染物质。同样，工程师们也正在努力设计新的发电厂，确定新的建厂地点，把对环境的危害减少到最低限度。然而，在我们拥有一个“干净”的世界之前，我们还有很长的路要走。几乎所有的国家都在努力预防和控制空气污染。看来环保主义者必须完成的任务似乎没有结束。人们将不断找到控制污染的新方法。

人类活动所造成的“人为污染”，是影响空气品质的主因，它的来源可分成下列3类：

1. 工业污染源——火力发电厂及各种类型的工厂，在生产过程中，燃烧燃料所排放出的废气、烟尘等，若不经适当处理，会严重的污染空气。

2. 交通污染源——汽车、飞机、火车和船舶等交通工具，其排放出的废气中含有一氧化碳、氮氧化物、碳氢化合物及铅等污染物。这些交通污染源和工业污染相比，是比较小型、分散、流动的，但是因为数量庞大，所以排出的污染物的总量，也是具有相当的破坏力。

3. 生活污染源——日常生活也会产生污染空气的物质，如香烟、炒菜的油烟，以及由冰箱、冷气泄漏出的冷媒等，都会污染空气。

The environment is everything around us,for example,air,water,animals,plants,buildings and so on.They all affect us in many ways and closely related to our lives.People cant live without the environment. Everybody needs to breathe air,drink water and eat food every day.We burn coal to keep warm,and we use wood to make paper.As a result,we become the part of the environment.

The environment has been getting wores and wores for many years.We have been upgrading our living standard, meanwhile the environment has been polluted.Somke form factory chimneys pollutesthe air.Machines and engines make noises that annoy us constantly.Animals are homeless because the forcests are decreasing every minute.Streets are crowded with people and vehicles.The environment painful for us to live in it now.So its time to solve those problems.

Fortunately,it isnt too late to correct our mistake.People are coming to realiza the importance of the environment.We have begun to try our best to improve it.Laws are being made dealing with air, water and noise pollution.The river be bright,the sky will be clear,the flowers will be beautiful,and the sunbeam will be dazzling and pretty.We believe that we wil be able to save our environment and live in a better world
