[关于环境污染的大学英语作文

Where is my home?

Some fish are forced to leave polluted water and are flying in the sky. But unfortunately, air is also so polluted that they have to wear masks. Each of them is crying, “Where is my home?” What a terrible sight!

Mankind has brought so much pollution. Waste is being poured into rivers and seas. Poisons to kill pests in farming and chemicals go into rivers and seas, too. Poisonous gasses from factories also make the air so dirty. The whole balance of nature is being destroyed as a result of our ignorance of the environmental protection.

Personally, man can not live alone on the earth. Should fish die from serious pollution, so would man! It is high time we did something to prevent such a scene from happening.

【译文】

何处是我家?

一些鱼类被迫离开受污染的水，并在天上飞。但不幸的是，空气污染，也使他们不得不戴上口罩。他们每个人都在哭，“我的家在哪里?”这太可怕了!

人类带来了如此多的污染。废物被排入河流和海洋。毒药杀死农业害虫和化学品进入河流和海洋去，太。从工厂有毒气体也使空气这么脏。整个自然界的平衡被毁坏了我们对环保的无知造成的。

就个人而言，人不能独自生活在地球上。如果鱼死了严重的污染，将男人!现在是时候我们做了一些，以防止发生这样的场面。

Too many cars have caused a lot of serious problems in our world.

Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities.

One possible solution is to design and develop clean cars and clean fuels.

In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as petrol.

Another solution is to develop modern public transportation systems and restrict the use of private cars.

If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars.

Thus, the total number of cars in big cities will reduce greatly.

On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.

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。

Write a passage with the words and phrases given：the problem of pollution， cause， artificial substances， release， waste products， industrial production， consumption of goods， bring it under control， agriculture， chemical substancea. Environmental Pollution I read a piece of news recently. It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular. Why？ ——Fresh air is getting less and less in Japan， and so is it in the U. S. A. In fact， environmental pollution is a very serious problem the whole world is facing. it is mainly caused by the waste products released from artificial substances， industrial production and increased consumption of goods. Bedsides， the use of chemical substances in agriculture also causes environmental pollution. Look at the sky， you can see that dense smoke is being released from the high and big chimneys；

those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons f waste products are heaping around us. How to change this condition？ More and more countries are trying to work out some effective means to bring it under control， but no great success has been made.

我的家乡在千岛湖，这儿有一片片郁郁葱葱的森林，清澈见底的湖水，湛蓝深远的天空，清新甜润的空气。

可惜，家乡人一些无意识的行为，还在影响着这儿的环境，比如过年过节燃放烟花爆竹，就严重地污染了空气(今年算我们家污染的空气最多了)。就拿我们家来说说吧。

除夕夜那天，在吃年夜饭前，爸爸先去楼下放鞭炮。噼里啪啦鞭炮声响起，顷刻间楼下变成了天庭，看不到地面，仿佛全是云，我就像置身在云海里，浓浓的硝烟弥漫着，给人一种窒息的感觉。

晚上就有更大的浓烟了。

我们先看了联欢晚会……随着电视节目的倒计时，“五、四、三、二、一”，几乎同时我和爸爸一起抬起了鞭炮去楼下放，迎接新年的到来。

噼里啪啦，只看见鞭炮爆炸的火花。遭了，没法呼吸新鲜空气了。我以最快的速度跑进了家，关上门、关上窗户。很用力的喘气儿。

那一夜，鞭炮声一直响了几个小时，闹得我整夜没睡好觉。不是梦见我炸伤别人，就是别人炸伤我，害得我总是惊醒。

我觉得要想让环境重新好起来，应该少放鞭炮、少抽烟、让我们的环境像原先那样美丽，迷人吧!

In this picture a man rudely opens a garbage can and violently throws all kinds of waste into it. however, the box is not an ordinary trash can, but is, as a matter of fact, the earth. it is where survive, breed, and prosper. but as the drawing indicates, earth does not receive an equal repayment. quite the contrary, one of the biggest "gifts" humans return to earth is an unbelievable amount of trash.the picture purposefully points out a kind of pollution that arouses little public attention, that is, garbage. the past century has witnessed an unprecedented increase in garbage output, most of it technological products that are difficult to be decomposed through natural processes, such as plastics and glass. furthermore, a recent report released that several major chinese cities are already surrounded by circles of trash in the suburban areas, polluting air, water, and earth.

Hence, the issue of waste pollution needs to be addressed as one of the priorities that demand social efforts. only through a holistic system of trash disposal can this problem be fully solved. moreover, we should advocate a more frugal lifestyle so as to reduce the growing scale of waste pollution.

[大学英语作文环境污染

it was the industrial revolution that gave birth to environmental pollution as we know it today. the emergence of great factories and consumption of immense quantities of coal and other fossil fuels gave rise to unprecedented air pollution and the large volume of industrial chemical discharges added to the growing load of untreated human waste. chicago and cincinnati were the first two american cities to enact laws ensuring cleaner air in 1881. other cities followed around the country until early in the 20th century, when the short lived office of air pollution was created under the department of the interior. extreme smog events were experienced by the cities of los angeles and donora, pennsylvania in the late 1940s, serving as another public reminder.环境污染现象英语作文二

industrial pollution is clearly one of the biggest contributors to our polluted landscapes, at least here in the west. there are plenty of causes of land pollution, from urban and industrial ones, to rural and agricultural sources.

but which kinds of land pollution are the most important? and what can we realistically do to help prevent more pollution?

this part of the site gives an overview of some of the most important causes of land pollution, including industrial pollution.

there are also some recommendations for helping avoid domestic land pollution incidents.

click here for some good reading on industrial pollution and land pollution causes and solutions.

Cars have created a lot of serious problems in our world.

All the time, they are pumping huge amounts of waste gases into the atmosphere, causing disease and even death.

One possible solution is to design and develop clean cars and clean fuels.

But it may take decades for the new models to completely replace the traditional ones.

Another solution is to develop modern public transportation systems and restrict the use of private cars.

If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not drive private cars.

On the whole, the elimination of air pollution needs the co-efforts from the government and the public.

This problem will be solved only with the help of science and technology.

Protecting the Environment

With the improvement of our living standard, more and more people can afford a car. As a result, our roads are more often than not crammed with cars. However, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. So nowadays we advocate to lead a low-carbon life.

My suggestion is we should ride bikes more often instead of driving cars.By riding a bike, we can not only exercise our body but also protect our environment. Why not have a try, my dear friends?

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.

导语：近年来我国多地雾霾天气不断增多，极大地影响了人们的健康与生活。下面是yuwenmi小编为大家整理的相关作文，欢迎阅读与借鉴，谢谢!

With the broadcast of smog,this long-standing environmental problems,become the hot discussion once again.According to some reports,the frequent appearances of smog obscure the clarity of the sky recently.Some people drove slowly on the road because they could not see clearly. They also suffered from many illnesses caused by smog.

Smog is the general expression of various higher-than-permitted suspended particulate matter (such as PM2.5) in the atmosphere,which express the state of air pollution .It contains fog and haze,both of them are disastrous weather. Fog consists of a large number of tiny water or ice crystals.Its actually a harmless natural phenomena that makes visibility worse .Haze is air pollution in which is mixed up with dust, smoke and other dry particles. The components that make up haze may have negative effect on peoples health, especially for children and the old.

So its necessary to find out the reason why leads to smog and work out the resolution.If we trace the cause for smog weather ,the main points are natural causes that include windblown dust and manmade causes which include three aspects.Firstly,china s air quality standards are rather lax and evaluation factors are limited.Secondly,some enterprises just go for economic interests instead of observing relevant law and regulations.Obsolete equipment、industrial fuel burning and manufacturing operations are high likely to emit much wasted air.Thirdly,across our society ,relevant protection awareness has not built up.Just for the sake of convience to go out,people rely more and more on travelling and working by car while car is the main cause for smog.

To settle this problem,a series of meaures should be taken as follows.Primarily,we should establish a sound control system of smog. Not only can environmental protection departments strengthen air monitor,but government should enact more strict laws and regulations.Moreover,Reduce pollution sources is the fundamental solution to cut air pollutants. For example,we can reduce the amount of fuel vehicles or close down high polluting enterprises.Developing green and energy-saving energy can lower the emission of smog.Last but not least, People should do personal protection.They need to reduce the time for outdoor sports and pay attention to rest in smog days.Everyone all over the country should take measures to reduce the smog weather. We can use more public transport such as the bus and the underground so that the number of cars will be limited.Also,people should plant more trees. As far as Im concerned ,if we work together to do such measures ,smog weather will vanish completely and we will get clear and blue sky.

随着烟雾的传播，这个长期存在的环境问题再次成为人们讨论的热点，据一些报道，烟雾的频繁出现模糊了最近天空的清晰度，有些人因为看不清楚而在路上缓慢行驶。他们也遭受了许多由烟雾引起的疾病。

烟雾是大气中各种高达允许悬浮颗粒物(如PM2.5)的普遍表现，它表示大气污染的状态，含有雾和霾，两者都是灾害性天气。雾由大量的细小的水或冰晶组成，实际上是一种无害的自然现象，它使能见度变得更糟。Haze是空气污染，它与灰尘、烟雾和其他干粒子混合在一起。构成雾霾的成分可能对人们的健康产生负面影响，特别是对儿童和老年人。

因此有必要找出原因，导致烟雾和工作的决议。如果我们追溯雾霾天气的成因，主要是自然原因，包括风沙和人为原因主要有以下三个方面：首先，中国的空气质量标准是相当宽松的评价因素是有限的。其次，一些企业只是去代替观察相关的法律和法规的经济利益。设备陈旧、工业燃料燃烧和生产经营高可能发出多浪费空气。然后，在我们的社会中，相关的保护意识还没有建立起来。只是为了方便出门的缘故，人们越来越依赖旅行和工作的汽车，而汽车是主要原因烟雾。

为了解决这个问题，应采取一系列措施如下。首先，我们应该建立一个健全的烟雾控制系统。环保部门不仅要加强大气监测，而且要制定更加严格的法律法规，减少污染源是减少大气污染物的根本途径。例如，我们可以减少燃料量或关闭高污染企业，发展绿色、节能的能源可以降低烟雾排放。最后但并非最不重要的，人们应该做好个人防护。他们需要减少户外运动的时间和关注在烟雾天休息。全国各地的人应该采取措施减少烟雾天气。我们可以使用更多的公共交通工具，如公共汽车和地铁，这样汽车的数量将是有限的，人们也应该种植更多的树。就我而言，如果我们共同努力，采取这样的措施，烟雾天气将完全消失，我们将得到明确和蓝天。

It is universally acknowledged that tour can make people feel happy; traveling is a good way to relax oneself. Tourist data shows that people in China made a great contribution to the world tourism, and it’s more and more popular for people to go out for vocation. Though reports criticized that tourism had brought harm to the environment, I still believe in the rising pace of tourism.

Well, there is no denying that at this moment, tourism has caused some problem to the environment, but what I want to emphasize is that such damage are raised by people, as long as we improve the environmental consciousness of our citizens, as well as perfect the public facilities, such as adding more dustbins to convenience tourists; building cafeterias to offer meals to them. I believe within a period of time, the situation can be relived.

Environment itself also has the ability to recover itself. Years ago, when there were no so many tourists, and no industrial pollution, trees grew well, flowers smelt good, sky was blue, water was clean. Why the nature seems so unnatural now? It must be our own problem, for we have took too much, but paid back too less. Think how we treat our land. It is really unfair.

Just as I mentioned before, tourism had brought great profit to our economic, whatever scenic spot it is, it must has the relationship with our land, our trees ,our water, etc., everything can’t separated from earth. So as you see, tourism won’t bring harm to the environment, but ourselves.

It is good for us to go out to feel different culture atmosphere, and to see different local conditions and customs, but remember, protect our nature resources.

With the remarkable improvement of peoples living standard, people tend to buy more goods. As a result, a plenty of plastic bags are threw around and caused white pollution. Not only does it do harm to the environment, but also give people the impression that the city is dirty. As we all known, plastic bags are non-biodegradable material and it will stay in the soil for a long time. What’s worse, the poison released from the plastic bags is harmful.

随着人民生活水平的显著提高，人们购买的商品越来越多。所以，到处都是塑料袋，造成白色污染。塑料袋不仅污染环境，也给人城市很脏的印象。众所周知，塑料袋是不可生物降解的材料，会长期留在土壤里面。更糟糕的是，从塑料袋中释放的有毒物质是有害的。

Being current generation of young people, we should take measures to control the use of plastic bags .We can substitute them with cloth bags or reuse them. And the government can make rules to avoid using them. If we do our best, the use of plastic bags can be reduced, thus the white pollution can be controlled.

作为当代年轻的一代，我们应该采取措施来控制塑料袋的使用。我们可以用布袋来替代塑料袋或者重复使用。政府也可以制定规定来避免使用塑料袋。如果我们努力做好，塑料袋的使用就可以减少了，从而白色污染也会得到控制。

In the past few decades, our Earth has changed a lot, but to the bad

direction. Among these changes, the air pollutions resulting from a huge number

of automobiles and coal-burning is almost the severest. The severe air pollution

alarms humans of the heavy load we have exerted on Earth by our insatiable

production and usage of automobiles. However, with the deepening of

urbanization, more cars are needed, which will make the air pollution worse.

Therefore, the following actions should be taken. First, we should apply the

most cutting-edge technologies in order to adopt new forms of energy as

substitutes for fossil fuels. Second, try hard to develop possible

transportation means, which are enviromental friendly. So that the citizens can

reduce the dependence on cars. In short, our humans should take responsibilities

for the air pollution and have to find ways to solve this problem.

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.

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.

Pollution: An Increasing Concern in China It is reported that ten big cities in China are being ranked among the top twenty cities with the highest pollution index in the world. This means it is high time we did something to bring the situation under control.Many factors are contributing to the deteriorating situation: industrial wastes pumped into the air, the lakes and rivers; a increasing number of automobiles crowding into the streets; the widespread use of plastic bags etc. To my view, stiffer laws and regulations must be implemented to check pollution. Industries that release wastes without permission should be heavily fined. Cars should be equipped to minimize the exhaust they release into the air. And the use of plastic bags and disposable meal boxes should be banned. Whats more, the media should play an important role in implanting a sense of environmental consciousness into peoples mind. If everybody works toward a common goal of making the environment better, we can create a cleaner and lovelier world for us and for the coming generation.

We know our hometown Anji is very beautiful, it is famous for the bamboos. And our hometown is an ecological country town, Most persons of Shanghai like traveling here. They called Anji is Shanghai’s flower back garden; The start of Huangpu River.

But now, in order to attract more tourists, develop the industry of our hometown. The leader of Anji government announced an order: work hard for five years , make a new Anji. That means we will develop the industry . Maybe It will pollute the environment.

It is good to see that nowadays both the government and people are becoming more aware of environmental protection and ecological balance. What we need to do now is to put our words into our deeds. And this should start from every and each one of us ,and it should start from small instances.

Yes, the government has been doing a great job. And what about us? What should we ourselves do? Some of us may think that is quite difficult. But it can be as simple as: do not litter; and strictly observe the rules and regulations of the tourist areas. Use as few plastic bags and boxes as possible. When traveling, and whenever possible, use public transportation instead of always driving your own car.

It is not that far to reach, right? It is just as simple as the famous slogan for travelers in TianHuangping says, “Please take away nothing but your smile, and leave behind your but your footprint.” I believe that more and more people now are becoming aware of the importance of environment protection. Just imagine if you sit in the Large Bamboos Sea and taste the white tea of Anji, that is so wonderful and comfortable. So now let us turn our passion into action. Give ourselves a brighter future to head to. Leave our next generation a brighter, greener, and better world to stay in. If not us, who? If not now, when?

Thank you very much !

Our modern city is too crowded， and to solve the problem， three proposals are put forward. Most people believe that we should fist practise the policy “Late Marriage” and “One Couple， One Child” in order to reduce the birth rate. Secondly， the city government must have a tight control over rural people entering cities to engage themselves in trade or do various physical jobs so as to lessen the pressure on the city caused by the increased population. Finally more and more people suggest that living blocks with shopping centers， schools， hospitals as well as cinemas and theatres round them or even satellite towns should be built in city suburbs or the countryside round the cities. In this way city citizens will be encouraged to move there to live and work. If these three proposals are well carried out， the city population will be greatly reduced.

我们现代城市太拥挤了，要解决这个问题，提出了三点建议。大多数人认为我们应该在政策上“迟婚”和“一对一”，以降低出生率。其次，城市政府必须严格控制农村人口进入城市，从事贸易或从事各种体力劳动，减少人口增长造成的压力。最后，越来越多的人建议，居住在购物中心、学校、医院、电影院、剧院等生活街区，城市郊区或郊区的城市应该建在城市郊区或城市周边的城市。在这个方式中，城市居民将被鼓励在那里生活和工作。如果这三项建议都很好地实施，城市人口将大大减少。
