英语作业6 --环境保护

1、很多人用这个版本Today the quality of our natural environment has become an important issue. The world population is rising so quickly that the world has become too crowded. We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do thi

2、s, life on earth cannot survive. Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution. Still more measures should be taken to solve environmental pro

3、blems. People should be further educated to recognize the importance of the problems, to use modern methods of birth control, to conserve(保存） our natural resources and recycle（再循环） our products. We are sure that we can have a better and cleaner place in the future.Environmental ProtectionNo one，rega

4、rdless 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 emiss

5、ions 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 action

6、s 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

7、we can take a comfortable world for granted again .环保没有人,不管是什么种族、宗教或民族、可以否认,我们生活的这个世界变得越来越无法忍受,因为全球变暖的影响。根据许多专家,甚至更大的影响仍在路上。有许多原因,是我们的问题。一方面,海域排放入大气的碳是导致,必将在未来的事业,具有明显的全球变暖根据理论。另一方面,知识的匮乏有关环境保护的重要性,阻碍了这个问题的解决。很紧迫的是,应立即采取有效的行动,马上。首先,种植更多的树木需要帮助改善和美化环境。除此之外,更严厉的法律关于全球变暖的燃料资源和不负责任的使用必须付诸实践,取得了较好效果。总之,还

8、有很长的路要走,我们就能采取一种舒适的世界是理所当然的了。Environmental ProtectionNowadays, the issue of environmental protection is becoming more important in society. We need to be more aware of the dangers of pollutions on earth as well as on our health. Although we're becoming more technologically advanced, our health i

9、s also taking it's toll. This is evident because we see more and more people wearing sunscreen because of the thinning of the ozone layer. Overall, a simple step in protecting our health and the environment is to recycle.We live in the world every day. We eat food, drink water, wear clothes, wat

10、ch TV, use computers and so on. We are producing waste every moment.    Generally speaking, there are four sorts of waste. They are material waste, organic waste, inorganic waste and poisonous & harmful waste. Now, we are going to talk about each sort of waste one by one. 

11、60;  Material waste: it means the waste of substance or things from which something else can be made. For example, people throw away the used metal products and buy a new one, so the old metal waste accumulates. At last, they become waste. For example, when people finish reading newspaper, the

12、paper will become waste. When the glass is broken, it also becomes waste. Nobody wants to use a broken window or drink with a broken glass or wear a pair of broken glasses. Once it is broken, it becomes waste. The rate of using plastics is increasing day by day. People use plastic bags because they

13、are convenient. When they get home, they throw the plastics way, paying no attention to the environment. The more convenience plastics brings to us, the more plastic waste is produced. This is called “white pollution” as most plastics are white. Some of our products we use every day are made of rubb

14、er, just like the tyres and the bottom part of our shoes. Its true that rubber plays an important role in our life. However, it also brings us some trouble when it has been used for a long time and becomes old. The old tyres become waste because it cant break down by nature. This is really a big pro

15、blem.    Organic waste: it refers to waste from living things, including waste from animals, plants and people. Some parts of vegetables are thrown away as waste because they dont taste good. In the past, people cooked their food using burning coal, so there left the burned coal, whic

16、h is useless, like the thrown vegetables. All this sorts of waste contain organism, so it is called organic waste.    Actually, we also have inorganic waste, the opposite to organic waste, including building waste, broken pottery and china, and cinder.    The last part

17、is harmful and poisonous waste, such as used batteries, electrical apparatus and medical supplies. Computers and TV sets are one part of electrical apparatus. You see, the old electrical apparatus can set off some dangerous rays and make the soil harder, even damage the under ground water. Mobi

18、le phones are as dangerous as computers and TV sets. As we know, X-rays can be used to examine patients, but the X-rays machines are dangerous when they are thrown away without any treatment. They cant be used to treat the sick, but they still can give off rays. For the normal people, they can be da

19、ngerous. So, we must think about this problem.     As waste has four sorts, we can sort them into each sort that they belong to. Its convenient to treat them after they are sorted. Then we can deal with them sort by sort. We have thought out some methods like storing them in orde

20、r to change them into plant food, or burning them in a huge stove and use the heat to make electricity. For the first way, the change rate is much too low and it may pollute the under ground water. For the second one, of course its wonderful if its easy to be tried out. But to build such a huge stov

21、e will cost too much. Not a good method. Now you see, treating waste is not an easy job.Protection of the EnvironmentOnce 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. Th

22、e 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

23、 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 arestill put into rivers.We

24、 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 available. Land for crops feeds five times more people than land where animals ar

25、e 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.保护环境过去，人们不必担心保护环境的问题

26、。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

27、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。雾霾The continous hazy weather in China has been effecting many people lately. Many people living in the effected areas wouldn't be able to get out of their hous

28、es without wearing masks. News media around the globe have been closely watching the situation, hoping for the better. Today the quality of our natural environment has become an important issue.Recently, haze weather has become a hot topic in large part of our country, for example Beijing, Changchun

29、 and Harbin. And the continuous hazy weather has been affecting many peoples health. So people living in the affected areas are forced to wear the masks to avoid breathing poisonous air. It is necessary to find out the reason why leads to this phenomenon and how to work out the resolution. This kind

30、 of air pollutants is mixed up with dust, smoke and other dry particles, and it obscures the clarity of the sky. On one hand, natural sources include lots of windblown dusts and many soot from wildfires. On the other hand, manmade sources contain a great number of motor vehicles, industrial fuel bur

31、ning residues and manufacturing operations. However, our country's air quality standards are rather lax and evaluation factors are limited, so more and more people think that current air appraisal system has plenty of defects. Besides, for our society, relevant environmental protection awareness

32、 has not built up all around us so that people have not formed a habit of using green products and saving energy as much as possible.For the government, it is urgent that immediate and effective measures should be taken to solve the serious environmental problem. For example, one of effective soluti

33、ons to help eliminate haze is to limit the emissions of chemical industry during their manufacturing processes. For us, people should enhance environmental protection consciousness gradually. In a word, only in those ways can we have a better and cleaner environment in the future.One of effective so

34、lutions to help eliminate haze is to make some chemistry changes during the manufacturing process, so it could reduce harmful emissions which are produced by manufacturing operationsSecond, some people just go for economic interests instead of turning out products according to relevant law and regul

35、ations. They tend to use obsolete equipment in which they are high likely to emit a great deal of wasted air. Third, across our society ,relevant protection awareness has not built up so that people havent formed a habit of using green product and saving energy as much as possible.Just for the sake

36、of convience to go out,people rely more and more on travelling and working by car while car is the main cause for the haze weatherTo settle this problem,a series of meaures should be taken as follows.First ,we should strengthen air monitor to lower the levels of small particulate pollutants.Second,w

37、e should enact more strict laws and regulations and keep perfecting our current law on environmental protection to regulate people 's daily action and the industrial production and punish those factories that ignore the protection and keep emitting dangerous material that cause haze. Third,we should develop green and energy-saving energy to lower the emission of haze and improve air quality.As far as i am concerned ,if we work together to be able to do such measures ,our environment will getting
