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 needenergy, 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 airpollution 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 bethat 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 tasksthat environmentalists will be required to do. People will continually find new ways to control pollution.

Today the quality of our natural environment has become an important issue. The world population is rising so quickly that the world has become too crowded.
今天，我们的自然环境质量已经成为一个重要问题。世界人口增长如此之快，世界已变得过于拥挤。
We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive.
我们正在利用我们的自然资源，同时污染的危险化学品的环境。如果我们继续做这个地球上，生活无法生存。
Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stopenvironmental pollution.
有关人士取得了一些在环境保护方面的进展。许多国家的政府已建立了法律保护，空气，森林和海洋资源，并停止对环境的污染。
Still more measures should be taken to solve environmental problems. People should be further educated to recognize the importance of the problems, to use modern methods of birth control, toconserve our natural resources and recycle our products. We are sure that we can have a better and cleaner place in the future.
但更应采取措施来解决环境问题。人们应该进一步的教育，认识到问题的重要性，使用现代节育方法，以保护我们的天然资源和循环利用我们的产品。我们相信，我们可以有一个更加美好，更清洁的地方
篇3
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 poisonousgas 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 warnedthat 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 anincreasingly 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 pollutionfrom 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 thisway can we really solve the problem of air pollution caused by automobiles.
