空气污染英语作文一:Air pollution
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.

health, surrounded by, smog, anything but, gases, impurities, absorb, poisonous, try hard, blacked out
We all know that clean air is important to good health. Wherever you go and whatever you do, you are always surrounded by a sea of gases that we call air. If there are impurities in the air, they may be absorbed by our bodies and make us ill. We need clean air, but unfortunately, air pollution is globally present, especially in cities.
Many large cities are anything but pollution-free. Our cities have many factories, which we need to make food, clothing and other things. Every year these factories pour millions upon millions of tons of smog into air. Power plants and houses that burn coal add greatly to air pollution. Besides, there are more cars in cities now. Once out on the streets, they will take in fresh air and replace it with poisonous gases.
Our country is trying hard to prevent and control air pollution. As long as every citizen also realizes its importance and makes join efforts, the day will e soon when people will take in only clean air. Then, the sunlight will no longer be blackened out by smoke and soot.
空气污染英语作文三:Air pollution
Air pollution es 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 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.

英语作文—空气污染 Pollution is being 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.
[10建议措施段]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.

篇三:空气污染的英语作文
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 pletely 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.

篇一:空气污染 Air Pollution
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.
在过去的几十年中,我们的地球发生了很大变化,但是是往坏的方向。在这些变化中,大量汽车和煤燃烧产生的空气污染是最为严重的。严重的空气污染警告人类,我们无休止的的生产和使用汽车给我们的地球带来了沉重的负荷。然而,随着城市化的加深,汽车的需求量也越大,这会导致空气污染更严重。因此,我们应该采取以下行动。首先,我们应该运用最尖端的技术,以新型能源作为化石燃料的替代品。其次,努力寻找可能的环境友好型交通方式。这样城市居民就可以减少对汽车的依赖。简而言之,人类应该承担空气污染的责任,寻找解决这一问题的方法。

If there are impurities in the air, they may be absorbed by our bodies and make us ill. We need clean air, but unfortunately, air pollution is globally present, especially in cities.
