[关于环境保护问题的英语作文

Recently, a Chinese student who studied abroad delivered a speech at the

graduate ceremony. Her speech soon became the hot issue, because she criticized

Chinese air pollution, which was a great threat to her health. Though her speech

had exaggerated the problem, it is true that China has faced many pollution

problems. The haze in Beijing is famous around the world, which is the

punishment for human to ruin the environment. It needs time to fix the problem,

but there is no need to deny our country. Even for the developed countries, they

have once faced such problem before. We can do something in the daily life to

protect it, such as do not throw away the rubbish.

Where is my home?

Some fish are forced to leave polluted water and are flying in the sky. But unfortunately, air is also so polluted that they have to wear masks. Each of them is crying, “Where is my home?” What a terrible sight!

Mankind has brought so much pollution. Waste is being poured into rivers and seas. Poisons to kill pests in farming and chemicals go into rivers and seas, too. Poisonous gasses from factories also make the air so dirty. The whole balance of nature is being destroyed as a result of our ignorance of the environmental protection.

Personally, man can not live alone on the earth. Should fish die from serious pollution, so would man! It is high time we did something to prevent such a scene from happening.

With more and more cars coming into our families, we are happy that it has greatly improved our life. But unluckily, it has also brought many problems, such as heavy traffic and traffic accidents.

Traffic safety is everybodys business. We must obey the rules. For example, we must walk on walk side, when we cross zebra – crossing, stop and look right and left, then go across fast. Don’t play football on the road .we can tell our parents not to drink before they drive, not to run through red lights, not to talk and laugh while driving etc.

We can say cars are coming into our life, but only when everybody thinks traffic safety is everybodys business can we be safe driving on roads and walking on sidewalks.

Today，pollution has become a serious problem to us. It means that the air，seas，rivers and land are polluted by waste or poisonous things.

It does harm not only to human beings but also to animals .

We cannot have fresh air because many factories have the poisonous smoke sent into the air. Beautiful parks are made dirty by plastic tins and bags.

Fish die from the polluted water. It is said that strange diseases have appeared in some places because of pollution.

I hope scientists can find ways to solve the serious problem.

We are looking forward to seeing the clear sky，clean rivers and beautiful parks again.

I live in a city, since I was small, I witnessed all the things happened in this city. Now, in my eyes, after so many years, the city has changed so much. First, the transportation has become fluent.

Many years ago, there were less bus stations, people always needed to changed their lines by many cars.

But now, almost all the places can be reached by bus, people don’t need to change the line. Second, the buildings are enlarging, this reflects the city’s economy develops fast.

Indeed, I can go to many newly built public places to have fun, some are for children, some are for the old, all of these are good for people’s communication. The city’s change reflects people keep pace with time.

我住在一个城市，当我很小的时候，我目睹了发生在这个城市的一切事情。现在，在我眼里，交通变得便利。很多年以前，公共汽车站点很好，人们总是需要通过换车来改变路线。现在，几乎所有的地方都可以通过公交车到达，人们不用改变路线。第二，建筑正在扩大，这反映了一个城市经济的快速发展。确实，我可以去很多新建的公共场所玩，一些是给孩子的，一些是给老人家的，所有的这些对于人们的交流是有用的。城市的改变反映了人们与时俱进。

All of us want to be healthy. First，we should get enough sleep during the night. We can go to bed early and get up early. Staying up late is bad for our health.

Third，we should do more exercise to build up our bodies. Finally，we should be happy everyday. Because smile will make us younger。

That is my advice.I hope you are healthy and enjoy your life。 （2）How to keep healthy /fit?

As a middle shool student. first youd better do more exercise such as playing ball games ，running， swimming and jumping ropes(绳子)。Then you should pay attention to your diet or meals. Dont eat too much meat or suger，but more vegetables and fruit.Third you need enough sleep or rest .

It is universally acknowledged that tour can make people feel happy; traveling is a good way to relax oneself. Tourist data shows that people in China made a great contribution to the world tourism, and it’s more and more popular for people to go out for vocation. Though reports criticized that tourism had brought harm to the environment, I still believe in the rising pace of tourism.

Well, there is no denying that at this moment, tourism has caused some problem to the environment, but what I want to emphasize is that such damage are raised by people, as long as we improve the environmental consciousness of our citizens, as well as perfect the public facilities, such as adding more dustbins to convenience tourists; building cafeterias to offer meals to them. I believe within a period of time, the situation can be relived.

Environment itself also has the ability to recover itself. Years ago, when there were no so many tourists, and no industrial pollution, trees grew well, flowers smelt good, sky was blue, water was clean. Why the nature seems so unnatural now? It must be our own problem, for we have took too much, but paid back too less. Think how we treat our land. It is really unfair.

Just as I mentioned before, tourism had brought great profit to our economic, whatever scenic spot it is, it must has the relationship with our land, our trees ,our water, etc., everything can’t separated from earth. So as you see, tourism won’t bring harm to the environment, but ourselves.

It is good for us to go out to feel different culture atmosphere, and to see different local conditions and customs, but remember, protect our nature resources.

我们最后去的公园是在怀俄明州的黄石国家公园。这是我第一次看到天然的间歇性喷泉。我从以前就一直想要能够近距离地观看它并用我的照相机把那些景色拍下来。

我们大家都一致认为这次的旅行是很过瘾的。孩子们还想明年再去，但是再来这次，我认为我们不会一次参观那么多地方了。

The situation of the countryside is not good.Too many people live in the countryside and we dont have enough farm land for them.

Fortunately,our government has realized the problems and has attached great importance to them.The government is trying its best to create more jobs and improve traffic systems.Moreover,the one-child policy has helped a lot.

众所周知,中国拥有世界上最大的人口超过1300000000。如此大的人口在城市造成一些问题,这是失业。很多人聚集在城市和工作是不够的。一些毕业生找不到工作,尽管他们已经离开学校好多年了。此外,交通堵塞造成的另一个问题是巨大的人口。有太多的汽车在公路和街道。

农村的情况是不好的。太多的人生活在农村,我们没有足够的农田。

幸运的是,我们的政府已经意识到问题,并重视他们。政府正在尽力创造更多的就业机会,改善交通系统。此外,独生子女政策已经帮助很多。

Environmental problems are becoming more and more serious all over the world. With the development of industry and agriculture, cars make great noises and give off poisonous gas. Trees on the hills have been cut down,and waste water is being poured continuously into rivers.

Furthermore,wherever we go today, we can find rubbish carelessly disposed. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to mans existence.

We must face the situation that exists and take actions to solve our environmental problems. For instance, new laws must be passed to place strict control over industrial pollution, the pub!ic must receive the education about the hazard of pollution and so on. We hope that all these measures will be effective and bring back a healthful environment.

环境围绕我们身边，例如：空气、水、动物、建筑等。它们从各个方面影响着我们的生活，与我们的生活密切相关，人们离开环境就无法生存。每人每天都要呼吸、喝水和吃东西。我们少煤取暖、用木材造纸。结果，我们也成为环境的一部分。

很多年以来，环境日益恶化。我们在提高生活水平的同时，也在导致环境污染。从工厂烟囱里冒出来的烟污染空气；机器和引擎经常发出恼人的噪音。因为森林每分钟都在减少，使动物们无家可归。街道上挤满了人和车辆。环境在我们的生活中是最重要的，但是现在它已经让人们讨厌。所以，该是解决这些问题的时候了。

幸运的是，现在改正错误还不晚。人们意识到环境的重要性。我们已经开始尽力改善环境。法律也开始涉及到空气、水和噪音等问题。将来，河流会更清澈，天空会更晴朗，花朵会更鲜艳，阳光会更灿烂、更温暖。保护环境会使我们生活在一个更加美好的世界中。

With the improvement of our living standard, more and more people can afford a car. As a result, our roads are more often than not crammed with cars. However, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. So nowadays we advocate to lead a low-carbon life.

My suggestion is we should ride bikes more often instead of driving cars.By riding a bike, we can not only exercise our body but also protect our environment. Why not have a try, my dear friends

each year there is an increasing number of cars on the roads as millions of new cars are produced. one out of six americans works at making cars, driving trucks, building roads or filling up gas. americans couldnt live without cars!

most americans would find it hard to imagine life without a car. however, some have realized the serious problem of air pollution caused by cars. the polluted air becomes poisonous and dangerous to health.

one way to get rid of the polluted air is to make a car without pollution. but to build a clean car is easier said than done. progress in this field is slow.

another way is to replace car engines with something else. inventors are now working on steam cars as well as electric cars. many makers believe that it will take years to develop a practical model for us.

to prevent the world from being polluted by cars, we have to make some changes in our lives. americans, for example, have to cut down on the number of their total cars.they are encouraged to use bicycles, which are thought to help keep the air clean.

Although the government has announced many criterious, the barbarous behavior can be seen everywhere. Such as throwing litter on the streets arbiitrarily, crossing the road when the red lights on, smoking at the public place and etc.

The Expo 2010 Shanghai China is coming, it is important for us to show a beautiful and clean environment to the world. A tidy enviornment can show the civilization of the city, and leave the foriengers a good impression. Moreover, a comfortable and beautiful city can let the citizens live happier end enjoy the life.

Therefore, the measures should be taken immediately. As a lovely citizen, we should not only obey the rules ourselves but also appeal other people behave theirselves. We can add more litter bins and slogans on the streets, plant more trees and decreas the factorys let-out.

Today， pollution has become a serious problem to us. It means that the air， seas， rivers and land are polluted by waste or poisonous things. It does harm not only to human beings but also to animals (It does harm to animals， as well as human beings.)。

We cannot have fresh air because many factories have the poisonous smoke sent into the air. Beautiful parks are made dirty by plastic tins and bags. Fish die from the polluted water. It is said that strange diseases have appeared in some places because of pollution.

I hope scientists can find ways to solve the serious problem. We are looking forward to seeing the clear sky， clean rivers and beautiful parks again.

Environmental Protection No one，regardless of race, religion or nationality, can deny that the world we live in is becoming increasingly intolerable because of the effects of global warming. According to many experts, even greater impacts are still on the way. There are numerous causes for this problem. On one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem. It is urgent that immediate and effective actions should be taken right away. First, more trees need to be planted to help improve and beautify the environment. Besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effect and achieved good results. In a word, there is a long way to go before we can take a comfortable world for granted again .
