英语四级大气污染作文

① 大学英语四级作文（环保方面）

A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.

一项新的研究结果提出警告：到2025年，世界上将有30%的人没有足够的水饮用。

A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East.

这项研究是由美国一家名叫“人口行动”的私立机构进行的。报告说现在世界上有三亿三千五百万人没有足够的水。这些人主要分布在非洲或中东的28个国家。

P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.

人口行动组织的研究人罗博特.安格曼说，到2025年大约三十亿人缺水。至少还有其他18个国家将可能面临同样严重的水短缺问题。人类对水的需求不断上升，但地球上水的还是保持不变。

Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.

安格曼先生说，水短缺的国家的人口增长率要高于世界其他地区的人口增长率。他还说这些国家的人口出生率将持续增长。

The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new instries often need a large amount of water when they are beginning.

报告表明，在未来，水资源的缺乏可能会导致一些严重的后果。首先它可能会产生更多的健康问题。水资源的缺乏就意味着饮用水不再有保障。安格曼先生说，诸如霍乱等在水中传播的疾病会使世界出现许多问题。水缺乏也会引起更多的国际纷争。各国可能由于水而发动战争。现在有些国家，例如埃及，荷兰，柬埔寨，叙利亚，苏丹和伊拉克等，60%的纯净水是从国外进口的。报告认为水缺乏将影响发展国家发展经济的能力。这是因为新工业在开始阶段经常需要大量的水。

The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.

人口行动组织的研究报告为世界的水短缺问题提出了几个解决的办法。第一，找到多用途的用水方法。第二，教育人们不要浪费水资源。第三就是少用农业水。

The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.

报告同时表明，控制人口增长是长远解决水缺乏问题不可缺少的措施之一。它说除非各国能通过限制生育来降低人口的增长，否则它们不可能提供干净的水。

Global warming a bigger threat to poor全球变暖加剧贫穷 气候变化急待控制

Global warming, modelled on computer here, kills more people than terrorism

Global warming threatens to reverse human progress, and make unachievable all UN targets to rece poverty(联合国所有减少贫穷的目标), according to some of the world's leading international and development groups.

In a report published today, Oxfam, Greenpeace, Christian Aid, Friends of the Earth, WWF(英国牛津救济委员会、“绿色和平”组织、基督徒互援会、“地球之友”组织、世界野生动物基金组织) and 15 other groups say rich governments must immediately address(致力于) climate change to avoid even "obscene levels(无法忍受的程度)" of worldwide poverty.

"Food proction, water supplies, public health and people's livelihoods are already being damaged and undermined," the report says. "There is no either/or approach possible(想找一个‘非此即彼'的办法是不可能的). The world must meet its commitments to achieve poverty rection and also tackle climate change. The two are inextricably linked(二者的联系是难解难分的)."

The report, which draws on UN predictions of the effects of climate change in poor countries over the next 50 years, says poor countries will experience more flooding, declining food proction, more disease and the deterioration or extinction of entire ecosystems(整个生态系统的退化甚至消失) on which many of the world's poorest people depend.

"Climate change needs to be addressed now. The poor will bear the brunt of the impacts. The frontline experience of many of us working in international development indicates that communities are having to combat more extreme weather conditions."

Climate change will play havoc（大范围的破坏；浩劫） with agriculture and water supplies and will increase diseases. "By 2025 the proportion of the world's population living in countries of significant water stress will almost double, to 6 billion people. Tropical and sub-tropical areas will be hardest hit - those countries already suffering from food insecurity(食品短缺)".

Poor communities mostly do not need hi-tech solutions, but would most benefit from ecation, research and being shown how to farm better. The report says unchecked global warming(尚未得到抑制的全球变暖), more than wars or political upheaval(政变), will displace millions of people and destabilise many countries.

② 急求一篇大学英语四级考试中关于低碳环保问题的写作作文，谢了！

低碳环保小论文
地球是我们的母亲，毫不保留地为人类提供各种赖以生存的资源，而我们却不知道珍惜，还随意地毁坏自然资，比如森林砍伐，比如废气排放，导致泥土流失，树木被黄沙替代，破坏性风暴增多，生物种类减少，这些都是人类造成的。

科学家发现，至少有100多种大气污染物对环境产生危害，其中二氧化硫，氮氧化合物，一氧化碳，氟氢烃等都对人体有着较大的危害。大气污染物在空气中积累导致空气质量下降，直接危害人类健康，并且使臭氧层受到破坏，致使全球气候变暖。环境问题已经发展成为全球性的问题了，甚至影响着全人类的生存与发展。

气候变暖真的导致灾难吗？人们的疑虑不是没道理的。二氧化碳的排放？这和我们有关系吗？当然，人类只要呼吸便会排放二氧化碳，可是总不能不让我们呼吸吧？这应该是那些轰轰向天空吐出一团团黑烟的化石能源企业的责任吧，化石能源消耗产生的二氧化碳才是导致气候变暖的罪魁祸首。可是我们和那些能源企业的距离真的不相干吗？会有谁想过，这些消耗制造大量二氧化碳的企业最终把生产出来的能量输送哪里？谁又是他们的消费者？我们的日常生活中，电脑，手机，热水器，空调，电灯……哪一样不需要消耗能量？在升入高空的二氧化碳中，你“贡献”了多少？

减少二氧化碳的排放，选择“低碳生活”是每个公民应尽的责任。电脑，电灯，空调，任何电器一旦不用了应随手关掉；手机一旦充电完成，立即拔掉充电插头；

③ 求空气污染的英语四级作文 air 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" graally 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.
[参考译文]
空气污染
空气污染来自工厂、电站和汽车。电站发出的烟雾中所含的化学物质造成很大的破坏。这些化学物质可以随风飘走几百英里，然后才随雨水降落地面。但是这种化学雨逐渐摧毁森林里的树木，杀死湖泊中的鱼。在德国，到1986年止，全国已经有过半数的树木被摧残。
空气被污染的严重事故不时地在发生。1986年俄罗斯一座核电站发生过一起严重事故。一团带有辐射的尘埃穿越了整个欧洲。据说，在俄罗斯有125 000人由于这次事故引起的疾病而死亡。
1984年印度一家工厂发生了一起严重事故，一团有危险的气体笼罩着博帕尔市，当晚就有2 500多人死亡，有成千上万人受伤，受伤者中有许多人双目失明。

Thus,we should take effective measures to rebuild our beautiful environment of the cities from now on. In my opinion,law and regulations should be enforced by the government and authorities to control the emission of polluting gas.To ourselves,we should enhance the awareness of environment protection and choose a green lifestyle to make contribution to our earth day from day.

⑤ 求英语四级环保作文一篇。

There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reced with the rapid growth of modern cities.
To protect the environment, governments of many countries have done a lot. Legislative steps have been introced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.
In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through ecation. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.
保护环境
目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，随着现代社会的迅速扩建，植被大大的减少。
为了保护环境，各国政府做了大量的工作。采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。因此，在当今的环保中政府起着最重要的作用。
我的看法是，为了保护环境，政府应当采取更具体的措施。首先，应当通过教育的方法使人们充分謒到环境保护的重要性。第二，应更加努力把计划生育政策付诸实施，因为人口多就意味着污染严重。最后，要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自己。

⑥ 谁可以给我篇有关[环境保护]的优秀英语四级作文！

Nowadays, the biggest problem in our world is the environment is broken. The environment around us gets worse and worse, and the environment pollution is becoming more and more serious all over the world. Many lakes and rivers are seriously polluted and much water is polluted by factories. Many trees are cut down, and the animals don’ have home to go. The earth is our home and it is our ty to take care of it for ourselves and our future generations. Good environment can make people feel happy and fit. And the bad environment will bring illness to people. To protect the environment means to improve our life. As a middle school student, we must do our bit towards protecting the environment. It is our ty to do that. But what can we do for our Mother Earth?
In my opinion, I think protecting the environment should from ourselves. We shouldn’t throw the rubbish everywhere. And we should also tell others not to do that. We should put the trash into their own houses—trash bins. Whenever and wherever we see litter on the ground, we should pick it up and throw it into trash bins. Never spit in public. And don’t draw on public walls. As we know, water is the limited resources, and it is very important for human beings, we can’t live without water. But some people don’t care about it, and many cities need water now. So we shouldn’t waste the water. How to save the water? I have some my own idea. First, we can use some water which we have used again. For example, we can use the water we wash rice to water the flowers. Second, we should turn off the tap when we leave. We should try to protect the water resource. To protect trees, we can go to plan as many trees as we can. We can use cloth bag instead of plastic bag while we are shopping.
And I think we should tell others to protect environment, too. We should stop the people who throw the trash on the ground, and tell them it’s wrong to do this. We can also write to the boss of factories which discharge the pollutant. We can call our friends to plant more flowers and trees together. We should let people realize the seriousness of the environment pollution.
“There is only one earth,” I hope everyone will protect the environment. If everyone makes their contribution to protect the environment, our earth will be more and more beautiful!

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 instrial nations. Automobile, trains, planes and busses need energy, too. Nearly all of this energy is proced by burning fuels. The burning proces wastes, some of which remain in the air, causing air pollution.
Scientists are finding ways to stop air pollution especially in big instrial 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.

The impact of air pollution on climate

Air pollution is now discussing how they affect climate. The most serious air pollution is generated by burning: the burning of sulfur in coal and oil, will proce sparse oxides; air to participate in high-temperature reaction, will proce nitrogen oxides; will proce incomplete combustion of hydrocarbons and carbon monoxide; while combustion of pyrolysis gasoline, but also release lead; ... .... However, even the cleanest fuel combustion will proce carbon dioxide. Of course, the animal's breathing process, the same release carbon dioxide, and that of carbon dioxide into the atmosphere, about 80% came from breathing, only 20% from fuel combustion. However, the burning destroyed the natural balance of carbon dioxide, so that the concentration of atmospheric carbon dioxide increased year by year, which may cause the "greenhouse effect", so that the earth's rising temperatures.
Turbidity current growth rate of the Earth, or even greater than the concentration of combustion caused by cO2 growth rate, therefore, atmospheric turbidity will influence the Earth's climate can not be ignored. The increase in turbidity over the world there are many reasons, such as fuel consumption increase, fuel increase in agricultural machinery, mechanized farming, and so an increase in Young earth.

In addition to the greenhouse effect and atmospheric turbidity may affect the Earth's climate, other factors such as sunspot activity, etc., to some extent also affect the Earth's climate. Sunspot activity since 1900 are constantly increasing. As the sunspot can increase the amount of solar radiation and thus cause rising temperatures.

The air pollution on the Earth's climate, they are not scientifically conclusive evidence on the. Most of was a bold extrapolation.
