如何减少空气污染的英语作文1

How to stop air pollution

Nowadays,stopping air pollution has become the common issue that concerns the governments of many countries and people of all walks of life . Air pollution has caused a series of environment problems,such as the green house effect,damage to the ozone layer and acid rain. They all pose a threat to human living condition and health. Therefore,effective measures should be taken to stop air pollution. First,the government must make sure related laws are put into practice. Those who give off waste gases into the air directly without disposal would be punished. Second,people get education about what they could do to stop air pollution. Everyone using more public transportation and less private vehicle will reduce emission dramatically. Finally,let the forests play a positive rule. We need to plant more trees to purify the air instead of cutting them down. However, as a famous saying goes: easier said than done . Only the whole world works together and everyone takes action can human being succeed in stopping air pollution.

如何减少空气污染的英语作文2

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.

如何减少空气污染的英语作文3

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.

Protection of the Environment

Once man did not have to think about the protection of his environment.There were few people on the earth,and natural resources seemed to be unlimited.

Today things are different.The world has become too crowded.We are using up our natural resources,and polluting our environment with dangerous chemicals.If we continue to do

this,human life on earth will not survive.

We realize that if too many fish are taken from the sea,there will soon be none left.Yet,with modern fishing methods,more and more fish are caught.We know that if too many trees are cut down,forests will disappear.Yet,we continue to use powerful machines to cut down more and more trees.We see that if rivers are polluted with waste products,we will die.Yet,waste products are still put into rivers.

We know that if the population continues to rise at the present rate,in a few years,there won t be enough food.What can we do to solve these problems?

If we eat more vegetables and less meat,there will be more food https://www.doczj.com/doc/0616216535.html,nd for crops feeds five times more people than land where animals are kept.

Our natural resources will last longer if we learn to recycie them.

The world population will not rise so quickly if people use modern methods of birth control.

Finally,if we educate people to think about the problems we shall have a better and cleaner planet in the future.

翻译:保护环境

过去,人们不必担心保护环境的问题.因为那时地球上人口稀少,自然资源似乎取之不尽.

如今,一切都改变了.世界变得拥挤异常.我们正在耗尽我们的自然资源,有毒化学制品的使用也正污染着环境.如果我们继续这样下去,地球上的生命将不复存在.

我们都知道如果从海里捕捉太多的鱼,海里就不会再有鱼了.但是,现代化的捕鱼技术使得捕鱼量越来越大.我们都知道如果砍伐太多的树木,森林就会消失.但是,我们仍旧使用强大的机械砍伐越来越多的树木.我们都知道如果河水被废弃物污染的话,

我们只有死路一条.但是废弃物仍然源源不断地进入河里

我们知道,人口继续照现在这个速度增长的话,不出几年,就会发生食物短缺.我们该如何解决这些问题呢?

如果我们多吃蔬菜,少吃肉类的话,我们就会有更多的食物.因为同样大小的土地如果种庄稼的话会比养殖动物多养活五倍多的人.

如果我们学会再利用的话,自然资源就能持续更久.

如果人们使用现代化的生育控制方法,世界人口就不会增长如此迅猛.

最后,如果我们能够教育人们都意识到这些问题的话,未来我们就会有一个更好、更洁净的星球.

如何制止空气污染

世界,杜绝空气污染已经成为各国政府和各界人士共同关心的问题.空气污染带来了一系列的环境问题,如温室效应、臭氧层破坏和酸雨等.这些环境问题正在威胁着人类的生存环境和身体健康.

因此,我们必须采取有效的措施来制止空气污染.首先,政府需要确保相关的法律得到了执行,那些排放未处理废气的人需要受到应有的惩罚.其次,需要教育人们如何行动起来停止空气污染,如果每个人都多用公共交通少用私家车就会减少大量的尾气排放.最后,应该发挥森林的作用,我们需要植树造林来净化空气而不是滥砍滥伐.

当然,俗话说,说起来容易做起来难.只有全世界一起合作,每个人都真正地行动起来,人们才能取得制止空气污染这场战争的胜利.

环境破坏的英语演讲稿及翻译

环境破坏的英语演讲稿及翻译 The world we live in is becoming more and more intolerable because of environmental destruction. For example , forest destruction results in decrease of planting land and unpleasant weather. In addition, man is faced with problems of water pollution and air pollution. A lot of measures have been taken. Planting trees helps improve and beautify the environment. Besides, laws concerning environmental protection have been put into effect and achieved good results.However, the problem of environmental protection remains far from being solved. On the one hand, the environment pollution and destruction are getting worse and worse in the modern world. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem. In a word, there is a long way to go before we enjoy a clean and comfortable world.我们生活的世界变得越来越难以忍受,因为环境破坏的原因。例如,森林的破坏导致减少种植的土地和令人不快的天气。此外,人类正面临的问题和被污染的空气污染的水。很多已经采取措施。植树有助于提高和美化环境。除此以外,环境保护-法律已经实施,取得了良好的效果。然而,问题的环保仍难以解决。另一方面,污染、破坏环境越来越糟在现代世界中。另一方面,缺乏知识的环境保护问题求解的制约。一言以蔽之,还有很长的路要走,我们享受了干净、舒适的世界。我们生活的世界界变得越来越难以忍受,因为环境破坏的原因。例如,森林的破坏导致减少种植的土地和令

I don't know who wrote these words, but I've always liked them as a reminder that the future can be anything we want it to be. We are all in the position of the farmers. If we plant a good seed ,we reap a good harvest. If we plant nothing at all, we harvest nothing at all. We are young. "How to spend the youth?" It is a meaningful question. To answer it, first I have to ask "what do you understand by the word youth?" Youth is not a time of life, it's a state of mind. It's not a matter of rosy cheeks, red lips or supple knees. It's the matter of the will. It's the freshness of the deep spring of life. A poet said "To see a world in a grain of sand, and a heaven in a wild flower, hold infinity in the palm of your hand, and eternity in an hour. Several days ago, I had a chance to listen to a lecture. I learnt a lot there. I'd like to share it with all of you. Let's show our right palms. We can see three lines that show how our love.career and life is. I have a short line of life. What about yours? I wondered whether we could see our future in this way. Well, let's make a fist.

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

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.

How do you see more and more people getting face-lifting now? 我认为现在最大的污染问题是空气污染。阴霾严重影响了我们的生活经历。尤其是在雾霾污染较严重的北京,人们因外出空气污染而不得不戴口罩,这给人们的生活带来了极大的不便。空气污染严重影响我们的健康。空气污染的主要原因是汽车尾气和工厂废气排放。鉴于这些原因,我们应该减少私家车出行,严格检查汽车尾气排放是否超标,工厂废气排放也应严格处理。只有这样,我们才能持续有效地减少空气污染,并有助于创造一个更清洁的环境。其次,改善天气条件和更多的蓝天也有助于改善城市人口的整体健康和福祉。 I think the biggest pollution problem now is air pollution. The haze has seriously affected our life experience. Especially in Beijing, where haze pollution is more serious, people have to wear masks when they go out because of air pollution, which also brings great inconvenience to people's lives. Air pollution seriously affects our health. The main causes of air pollution are automobile exhaust and factory exhaust emissions. In view of these reasons, we should reduce private car travel, strictly examine whether automobile exhaust emissions exceed the standard, and factory exhaust emissions should also be treated strictly. Only in this way can we continuously and effectively reduce air pollution and help to create a cleaner environment. Secondly, improved weather conditions and more blue sky days can also help to improve the overall health and well-being of the urban population.

关于空气质量的英语专业术语

关于空气质量的英语专业术语 这两天大家一定都很关注空气质量情况的播报,也许你会好奇空气质量指数到底是根据哪些污染物算出来的?各种等级的污染对我们有哪些危害?下面就来为大家科普下这些基础知识吧: 【关于空气质量的术语】 环境空气ambient air 指人群、植物、动物和建筑物所暴露的室外空气 空气质量指数air quality index (AQI) 定量描述空气质量状况的无量纲指数。 空气质量分指数individual air quality index (IAQI) 单项污染物的空气质量指数。 首要污染物primary pollutant AQI大于50时IAQI最大的空气污染物。 超标污染物non-attainment pollutant 浓度超过国家环境空气质量二级标准的污染物,即IAQI大于100的污染物。 总悬浮颗粒物total suspended particle (TSP) 指环境空气中空气动力学当量直径小于等于100μm的颗粒物。 颗粒物(粒径小于等于10μm)particulate matter (PM10) 指环境空气中空气动力学当量直径小于等于10μm的颗粒物,也称可吸入颗粒物。 颗粒物(粒径小于等于2.5μm)particulate matter (PM2.5) 指环境空气中空气动力学当量直径小于等于2.5μm的颗粒物,也称细颗粒物。 * 此前我们国家采用的空气质量标准是API (Air Pollution Index),也就是空气污染指数;但在2012年2月后进行了修订,改为AQI,最重要的一个变化就是加入了PM2.5的监测。 【AQI基于哪些空气污染物】 The AQI level is based on the level of 6 atmospheric pollutants: ①二氧化硫:sulfur dioxide (SO2) ②二氧化氮:nitrogen dioxide (NO2)

The first is Actuality of Air Pollution.Before talking about it,i want to mention the Definition of Air Pollution. Air pollution is the presence of undesirable material in air, in quantities large enough to produce harmful effects.It causes harmful effects on human health, property, aesthetics, and the global climate. 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(杂质)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. Along with the economical development, also caused serious air pollution. Countries also begin to pay close attention to the problem, and taken the relevant measures. Some countries have made about air pollution regulations and rules, and get substantially improved. But we are facing new
