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。

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” 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。

空氣汙染

空氣汙染來自工廠、電站和汽車。電站發出的煙霧中所含的化學物質造成很大的破壞。這些化學物質可以隨風飄走幾百英里，然後才隨雨水降落地面。但是這種“化學雨”逐漸摧毀森林裡的樹木，殺死湖泊中的魚。在德國，到1986年止，全國已經有過半數的樹木被摧殘。

空氣被汙染的嚴重事故不時地在發生。1986年俄羅斯一座核電站發生過一起嚴重事故。一團帶有輻射的塵埃穿越了整個歐洲。據說，在俄羅斯有125 000人由於這次事故引起的疾病而死亡。

1984年印度一家工廠發生了一起嚴重事故，一團有危險的氣體籠罩著博帕爾市，當晚就有2500多人死亡，有成千上萬人受傷，受傷者中有許多人雙目失明。

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。

在過去的幾十年中，我們的地球發生了很大變化，但是是往壞的方向。在這些變化中，大量汽車和煤燃燒產生的空氣汙染是最為嚴重的。嚴重的空氣汙染警告人類，我們無休止的的生產和使用汽車給我們的地球帶來了沉重的負荷。然而，隨著城市化的加深，汽車的需求量也越大，這會導致空氣汙染更嚴重。因此，我們應該採取以下行動。首先，我們應該運用最尖端的技術，以新型能源作為化石燃料的替代品。其次，努力尋找可能的環境友好型交通方式。這樣城市居民就可以減少對汽車的依賴。簡而言之，人類應該承擔空氣汙染的責任，尋找解決這一問題的方法。
