Air pollution,together with littering,____ many problems in

Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog.
Some air pollutants are poisonous. Inhaling them can increase the chance you'll have health problems. People with heart or lung disease, older adults and children are at greater risk from air pollution. Air pollution isn't just outside - the air inside buildings can also be polluted and affect your health.

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.

Air pollution is the human introduction into the atmosphere of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment. Air pollution causes deaths and respiratory disease. Air pollution is often identified with major stationary sources, but the greatest source of emissions is mobile sources, mainly automobiles. Gases such as carbon dioxide, which contribute to global warming, have recently gained recognition as pollutants by climate scientists, while they also recognize that carbon dioxide is essential for plant life through photosynthesis. 
The atmosphere is a complex, dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.

空气污染
可以写一下空气污染的原因,表现在什么地方,然后我们该怎么保护环境.
先构思好中文,直接在线翻译,注意好语法时态就好啦

专有名词是特定的某人、地方或机构的名称,即：人名,地名,国家名,单位名,组织名等等
专有名词的第一个字母大写.如：the Great Wall,China,Russia 俄罗斯 New York 纽约 United Nations联合国
普通名词表示一类人或东西或是一个抽象概念的名称,普通名词又可分为个体名词、集合名词、物质名词、抽象名词.
由此可见你的说法（sea ice ,air pollution两个词看做普通名词构成的专有名词）是不成立的
请多多指教

A.will have become
到2050年,(现在还没到,所以是将来时,而by.直到.通常要用完成时)
空气污染就会成为威胁到人类健康的一个严重的问题.
因为有一种影响/结果,所以一定要用完成,而时间还没到呢,所以要用将来.
即:将来完成时.
shall主要第一/三人称,
will第二人称,还可表示客观,shall多主观.

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.

Recently,the water pollution is getting worse and worse.Many people always throw rubbish into rivers.And factories are making the water dirtier.All these are harmful to the water.If we do not stop it,we will not have clean water.All of us will die.So we must save water.
We should do our best to protect the water.

在九十世纪末的时候,空气污染将会成为一个威胁人类健康的严重问题.
首先,空气污染是自己成为一个问题而不是被成为一个问题,所以不能用被动,所以先排除A、D,然后,九十世纪末还没到,是表示一个将来的时间状语,所以要用将来时态,再次,整道题的意思是过去某个时候开始到九十世纪末为止这一段时间内,空气污染成为问题.所以要用完成时态,所以总的就要用将来完成时态,所以选C

Air pollution is at its worst over big cities where millions of people live, work, and travel about in cars, buses, and trucks. Factory chimmeys can be fitted with devices to cut down[4] air pollution, but this is expensive. If better pubic transport and cycle lanes were available in towns and cities, people would be less likely to use their cars, reducing the overall amount of pollution.
Smoking cigarettes adds to the general levels of air pollution as well as damaging our health. Cigarette smoke contains chemicals that can cause cancer, a gas which stops oxygen being taken into the blood and a substance called nicotine, which raises blood pssure and makes the heart beat faster. No-smoking areas cut down on this pollution and save non-smokers breathing in other people's cigarette smoke.
air pollution 作文
求一篇英语作文the fight against air pollution
Air pollution has become a serious problem in recent years. There are a lot of causes. first of all, is the chemical noxious gases emission. We all know that there are a lot of of factories around the world, they are actually emitting such gases everyday. The second one is the sharp decrease of the forests. Forest is very important to our Eco-system, it can adjust the heat and balance the air. The third one is the urbanization. People tend to stay in the city where is actually an abnormal Eco-system. Many cities do not have a complete system of controlling the air pollution.
In order to solve such problems, I have some ideas.
First of all is to control the emission of noxious gases. A set of necessary standards is required. It is not allowed to emit some particular gases until they have been transferred to another kind of chemical substance that is harmless to environment. Second one is planting more trees. We have cut down a lot of trees. It does have side effect on the quality of air. By planting more trees, many environment problems can be solved rather than air pollution only.

Sandstorms and the dust and gases from volcanoes pollute the earth's atmosphere naturally.But the most serious kind of air pollution comes from people.Factories,power stations,and rehicles exhausts[1] pump harmful gases into the air,contributing to global warming,causing acid rain[2],and destroying the ozone layer.On a much smaller scale,air pollution causes all sorts of breathing problems.There are no simple solutions to air pollution,but people could reduce air pollution by saving energy and reducing harmful emissions from vehicle exhausts and power stations.
When a volcano erupts,dust is blasted[3] high above the troposphere and may take weeks to be carried around the weather zone,so cannot be washed out of the air by rain.It will eventually fall to the earth after a few years.

Different countries have different reactions and opinions regarding this protocol.For example,the United States of America and the Bush Administration decided that they were not going to be part of this protocol.The Bush Administration believes that global warming is not a problem that should concern them because they insist that there is no such thing as global warming.If the United States decides to be part of the Kyoto Protocol,the energy industry of this country will have a to spend $300 billion in order to meet the reduction of production of greenhouse gases required by the Kyoto Protocol.鈥淒onald Kennedy,editor of the respected journal Science鈥 agrees the administration is politicizing science more than previous administrations,鈥 says William Triplett in his article 鈥淪cience and Politics鈥?It is important to mention that President Bush and Vice President Dick Cheney have extensive professional and personal ties with the energy industry of the United States,which gave a big contribution to the Bush campaign and other republican senators such as Sen.James Inhofe,R-Okla.James Inhofe opposes the regulation of the production of greenhouse gases by the federal government because he claims that sound science,which is consistent and demonstrated scientific data,does not support the idea that such gases are provoking global warming.On the other hand,there are some Republican senators that oppose Inhofe鈥檚 idea.Senator Chuck Hagel,R-Nebraska,is one of the few leading Republican influencing climate change.鈥淸Hagel] introduced three bills designed to be economic jumper cables that would boost the development of clean-energy technologies鈥 says Amanda Griscom Little in her article 鈥淣ebraska Republican Chuck Hagel Chats with Grist about Climate Change鈥 published by Grist Magazine.These bills are focused on the exchange of international technology,which must be clean-energy technologies,and the authorization of $4 billion over five years to encourage the national development of non-polluting technologies.鈥淭he objective is to address the issue of greenhouse-gas emissions in a realistic and achievable way鈥 explains Hagel.Obviously the Bush Administration鈥檚 priority is to expend US money in defense and war.Moreover,they are trying to convince the world that humans are not causing global warming because they know that the US is the biggest polluting country in the world and it will cost the government a lot of money to make changes that will reduce global warming.I wonder what the purpose of spending all that money on a war that is supposed to protect the US citizens from other countries,when in the end we are all slowly killing each other by contaminating the earth.Another country like Venezuela,which is the third largest oil exporter in the world,is agreeable to approve the Kyoto Protocol.鈥淎lthough Venezuela is an oil exporting country,the amount of greenhouse gas emissions is relatively low,constituting 0.48% of global greenhouse emissions when the United States alone produces 35%鈥 says Ana Elisa Osorio,who is the Minister of the Environment and Natural Resources of Venezuela,in the article 鈥淰enezuelan Government Will Ratify the Kyoto Protocol鈥?Even thought Venezuela is not required by any international act to accept the Kyoto Protocol鈥檚 policies,the Venezuelan government is enthusiastic to cooperate.Osorio considers it to be really unsupportive for the United States to reject the Kyoto Protocol.She questions this decision based on the quantities of greenhouse gases that the US produces.
Global warming and climate change are affecting all life on earth and the solution to this problem is in our governments.Humans have suffered for many years because of the climate change,but most recently these changes have occurred dramatically,affecting the economy and life.Many countries have taken the right decision on becoming part of the Kyoto Protocol,but is alarming that the biggest polluting country,the United States,has rejected this convention in which its only idea is to save the planet from melting down.It is obviously unfair that the other 65% of the world,made up of many countries,has to pay the consequences of just one country that is creating 35% of the problem.The United States has always claimed that it wants to save the citizens of the world on every worldwide activity that they are part of,but I wonder why they don鈥檛 want to save the world that they are part.I believe that the only answer to this question is that President Bush doesn鈥檛 want to expend money on something that his father doesn鈥檛 tell him to.I just leave it to everyone鈥檚 mind to decide what is the right answer to this problem.
Nowadays there are fewer and fewer cinema-goers and the cinema is slack.However,there are more and more TV viewers.There are many reasons for this social phenomenon,but in general,they come down to three major ones.
First,film tickets are too expensive,while it doesn't cost much to watch TV at home.Besides,it is time-consuming and inconvenient to go to the cinema.Nevertheless,it is very convenient and comfortable to watch TV at home.You needn't go out but just need to turn on the television.Most important of all,if you don't like the film you'll have to sit through it; but if you don't like one programme on TV,you can shift to another.
However,some people still go to the cinema.They usually go to the cinema for the purpose of social contact.Young people go dating there.Other people go to the cinema as an activity.For example,schools often organize children to go to the cinema.Sometimes employees also go to the cinema with the film tickets presented by their institutions.
