We in xinjiang tarim river is the longest continental river in China, the tarim river shore in iminqak is can be used to absorb dirt wont appear sandstorm, but people in the upstream of tarim river large area of forest cut water makes the river downstream dry, killing millions of acres of iminqak.

But in our country, large and small hotel is full use of disposable chopsticks, as far as I know a tree grow fifty years of birch only ten hotel with the number of chopsticks a day, how many restaurants are there in China?

环境是我们人类赖以生存的活动空间，比如说：空气的质量、工地和汽车发出的噪音、水质的好坏、街道的整洁和城市的美观等等都属于环境.现在每天在电视和报纸上都可以看见讲环保的消息，说明大家都很重视环境。

这几年我们的长江、黄河上游的人们砍伐树木，不保护环境，使得长江、黄河上游的水和土壤流失的很厉害，长江下游经常发洪水，黄河的水里有好多泥沙。我们新疆的塔里木河是我国最长的内陆河，塔里木河岸边的胡杨林是可以用来吸住泥土不会出现沙尘暴，可是人们在塔里木河的上游大面积开荒截水使得下游河水干枯，造成上百万亩的胡杨林死亡。至使本来就很贫瘠的土地，更加沙漠化。我们乌鲁木齐的人家做饭、取暖的烟囱冒出来的黑烟和汽车尾气的大量排放使的空气被污染。使乌鲁木齐的冬天看不到蓝天，雪也是黑的。

我在电视看见韩国的饭店用的筷子都是金属做的，可以反复用。可是在我们国家大大小小的饭店全是用的一次性筷子，据我了解一棵生长五十年的桦树只够十家饭店一天用的筷子的数量，中国有多少家饭店?一天要用多少棵桦树啊!!

对于我们校学生来讲要保护环境，首先要从不要乱人垃圾果皮纸屑，见到有人乱扔垃圾要给他讲道理。大人们也不要砍伐树木，这样会污染环境。要从节约每一滴水、每一度电做起、从小树立保护环境的意识，做到保护环境，人人有责。使我们的家园更美好!

人们常说眼睛是心灵的窗户。窗户越明亮，我们看到的世界就越精彩。如果窗户落满了灰尘，我们将看不清这美好的世界。但很多人不重视保护自己的眼睛，导致了近视或弱视，给学习和生活带来很多不便。如果我们不保护自己的眼睛而导致失明，那么这扇心灵的窗户将会永远关闭。

近视的形成和个人的习惯有很大关系。有的同学玩电脑、看电视时间太长。有的同学写字姿势不正确，眼睛离书本太近。有的同学挑食，导致眼睛营养缺乏。有的同学做眼保健操的时候不认真，起不到保健作用。还有许多不良习惯都容易导致近视或弱视。

仔细想想自己也有这样的不良习惯，每次写完作业，我脑子里总是想打开电脑玩一会，结果玩起来就上瘾，有时妈妈叫我吃饭我都不愿意去。吃饭的时候我总是挑食，有肉就不吃菜，有菜就不喝汤。这些不良习惯经常会受到家长的批评，他们也经常提醒我要保护自己的眼睛。

爸爸经常告诉我，光学习好不行，视力也要好。很多工作都要求有一双好眼睛，比如飞行员、宇航员等。因为视力不好，将来不能做自己喜欢的工作，多么遗憾啊。现在很多同学都戴上了小眼镜，给学习和生活带来很多不便。庆幸的是我还没有近视，我一定克服掉不良习惯，做一个健康的小学生。

眼睛是心灵的窗户，我们要保护好自己的眼睛，让这扇心灵的窗户永远干净、明亮！

Everyone knows animals are our friends.So we should be friendly to them.But some people kill the rare animals,such as pandas,golden monkeys and so on in order to get money.It will cause these animals to disappear soon.I think our government should punish those people severely who kill the rare animals.It is our duty to protect the endangered animals.

Protect Our Environment It is important to beal with the rubbish in cities. Our world was colorful,beautiful and full of life. But these years, people have built many factories along rivers. Many trees have been cut down. Many animals have lost their homes. Factories cause pollution. Rivers become polluted. As a student, you should do every things in your everyday life to protect them. First, stop wasting more water. Second, throw waste things into different dustbins. For example, waste paper should be throw into paper recyclable bins. Third, stop cutting down trees. Instead, plant more. Fourth, pick up garbage in the park or on the road when we are free. Last, call on more and more people to pay attention to contrlling pollution. In a word, everybody has his duty to protect the world.

Water is indispensable to our life and the development of national economy. It is often described as the source of all living things and the lifeblood of agriculture and industry. Without it, nothing could grow and out world would become a terrible desert.

The world we live in is now faced with a severe shortage of fresh water. According to some official figures, more than 1,700 million people in the world dont have enough clear water to drink and over 25 thousand people die of water related diseases daily.

So, all of us should actively b save water. Its our obligation for the benefit of the future generations.

First of all, let me tell you a true event. That is my grandpa with me by boat from yichang to three gorges occurs when one thing.

We all got up that morning, the people on board, is preparing to play water to wash shu. But the faucet for half a day on the boat were down only a few drops of water, one asked, originally is the boat ran out of water! So, we only have stood in long lines, slowly, etc. Although I looked at the ship, the ship under a stream of water, but no one would like to use it. Because the water is so dirty, so HunHuang, who dare to use? Line only slowly, slowly, etc!

Although in the high-speed development of science and technology nowadays, but the impact on our environment. Reduced river pollution, air pollution, the trees, the increasing of the desert... All this is all thanks to the human! Countries while in value, although the world in value, environmental protection, what and how much these things figure up attention? In my opinion, is rare. Although countries in so to speak, but whats the use of words and not of deeds? Did just a few, too! Dont grab from main reason! You see, the Yellow River water is not still contaminated? So the factory does not still pollute the atmosphere? Should grasp, starts from the quality of people, quality grab, but the country and the world to do so? No! Just like to do even when you are done. In the polluted environment is not so?

Animals are extinct, flash floods in explosion, dust storms still exist... It fully shows the environmental pollution! Countries will only go to disaster relief, instead of simply grabbed, will only go to disaster relief, whats the use? Dont all kinds of disaster is still in? We should like lu xun. He had become a is in order to save the Chinese, and he found that it will not solve the fundamental, so he became a writer, to save the people of the spirit. Because this is the fundamental! So, we as the master of the 21st century, you should understand, what is the root of the damage to the environment, from the point to solve it. Work hard -- the 21st century we!

首先，我先给大家讲一个真实的事件。那是我随我的外公从宜昌坐船前往三峡时发生的一件事。

那天早晨，船上的人都起来了，正准备打水洗淑。可是船上的水龙头半天也只下来几滴水，一询问，原来是船上的水用完了!所以，大家只有排着长长的队伍，慢慢的等。我望着船下，船下虽然有着流不尽的江水，但却没有一个人愿意来使用它。因为江水太脏了，是那么的浑黄，又有谁敢去使用呢?只有慢慢的排队，慢慢的等!

如今科技虽然在高速发展，但这影响到了我们的环境。河流污染，大气污染，树木的减少，沙漠的增多……这一切的一切都是拜人类所赐!国家虽然在重视，世界虽然在重视，什么环境保护日，这些事又有多少人影起了注意呢?在我看来，是极少的。国家虽然在这么说，可是光说不做又有什么用呢?做了也只是少数罢了!根本没有从主要原因抓起!你看，黄河的水不是还在被污染吗?工厂不照样还在污染大气吗?抓，就应该从小抓起，从人们的素质，品质抓起，可是国家乃至世界这么做了吗?没有!即使做了也只是做样子罢了。环境不是照样还在被污染吗?

动物还在灭绝，山洪还在爆发，沙尘暴照样存在……这都充分说明了环境还在污染!国家只会去赈灾，而不去根本抓起，只会去赈灾，这又有什么用呢?各种灾难不还是照样在发生吗?我们应该像鲁迅一样。他当初从医是为了拯救中国人，而他发现，这解决不了根本，所以，他当了作家，去拯救人们的精神。因为这就是根本!所以，我们作为21世纪的小主人，就应该明白，什么是破坏环境的根本，从要点去解决它。努力吧――21世纪的我们!

关于保护动物高中英语作文1：Animals Need Protecting

Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.

Why should people care? Because we need animals, and because once they are gone, there will never be any more. Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or plant on the danger list. Slowly, the number of some animals in danger is growing.

I am a student from Xinhua High School in Chongqing，China. Informed that you have a vacancy for a student to serve as the spokesman for animals, I cannot resist my inner excitement,hoping to seize the opportunity to do something for animals .

In my mind，nothing can delight me so much as caring for animals. Wherever I go and whatever I do, I usually keep in mind that animals are angels from the heaven, which bring us endless comfort and pleasure. I have been a panda lover since my childhood. Panda is so lovely that brings fun to people and they are regarded as the treasure of our country. Unfortunately，such a rare species is now faced with the danger of being extinct。What I am eager to do is to raise people’s awareness of animal protection and appeal to more people to care for our earth companies.

关于保护动物高中英语作文3：How tu protect animals

It is known to everyone that the unrestrained slaughter of wild animals has diminished the number of some endangered species. More and more species are being driven to extinction every year. It is terrible to think that magnificent animals are being sacrificed to human vanity

There are already laws enacted to prevent the importation of rare animals and the products made from their flesh, skin and bones.

These laws must be strictly enforced. Violators of these laws must be severely punished .Moreover, the public must be informed about the natural treasures we stand to lose .If we don’t take immediate action, we will be depriving future generations of our most precious heritage.

In Taiwan, because most people do not understand the importance of wildlife, the wildlife is in a poor situation. We Chinese are fond of eating anything delicious, so there are many animals killed by hunters. People enjoy eating tigers, bears, birds, and lions, so there are fewer and fewer birds flying in the sky and fewer and fewer bears running here and there in the forest. Instead, we often see them for sale at the market. How poor they are! And how cruel we are!

In my opinion, we should try every possible way to preserve wildlife. First, no one is allowed to hurt any wild animal. Second, the authorities concerned should punish those who kill any wild animal. Third, we should pay more attention to those endangered species to protect them from being eaten. If we can do so, nature must become very beautiful.

Last week, I saw a very impressive documentary about panda. A professor

studied panda in the early 1980s went to the wild life and kept trace of wild

giant panda for many years. As a result, he found that it was human being that

made these lovely animals die out. At that time, many people believed that giant

panda became less because of the low rate of newborn babies. But it was not

true. People cut trees for making profit at that time. Panda lose homeland and

they lacked of food. Thanks to these valuable data, the government took the

policy to protect the animals. So today, the number of giant panda is

increasing. People realize the importance of protecting the environment and it

is the best way to protect wild animals, they are the indispensable part of the

nature.

It was a fine day today and the sun was bright.I visited Beijing Zoo with my classmate， He Song.The animals were so interesting that all the people loved them.When a bear asked for some food by waving its ann， a visitor threw something to it.At once I went up to him and said without thinking，Dont do that.Its bad for it.If you really love them， take good care of them。 His face turned red and answered he wouldnt do that again。

Although the world develops much faster and better, the resources on the earth get fewer and fewer.In order to protect them,something must be done.尽管世界发展得更快、更好，地球上的资源越来越少。为了保护他们，必须做些什么。

Save water. Water is the source of life. No water, no life. So its very important for us to do so.Not only should we protect drinking water and stop polluting it, but also make full use of it.节约用水。水是生命之源。没有水，就没有生命。所以这是非常重要的我们这么做。我们不仅要保护饮用水和停止污染，而且充分利用它。

Save electricity. It is crucial. We cant imagine what the life will be like without it.Everyone should do his best to save electricity. Dont forget to turn off lights or other electric machines when we finish working.节约用电。这是至关重要的。我们无法想象的生活就会像没有它。每个人都应该尽自己的最大努力节约用电。不要忘记关灯或其他当我们完成工作的电机。

Save forests. They are useful .Please stop cutting them down and use recycled paper instead. Make our world a green one to live in.拯救森林。他们是有用的。请停止切割下来，用再生纸代替。使我们的世界成为一个绿色的生活。

Recycle useful rubbish. Plenty of rubbish can be recycled like cans,paper, bottles, and so on. We can save resources in this way.回收有用的垃圾。大量的垃圾可以回收罐，纸，瓶，等。我们以这种方式可以节省资源。

The earth is our home and we have the duty to take care of it for ourselves and for our later generations. Fortunately, more and more people have realized these problems. Measures have been taken to cope with these problems by the government. Laws have been passed to stop pollution. I hope the problem will be solved in the near future and our home will become better and better

Harmony with the environment is that we live in on Earth, who is a natural son, and not only to natural persons as the conqueror, as we all know, there is only one earth and the mountains on Earth, the animals. Plant human cells, if it damaged, destroyed nature organizations, to the eradication of mankind. Therefore, the environment must be linked with social ethics, character education and practice acts as an important element of it. Everyone must fulfil its responsibilities and obligations to protect the environment.

译文：地球是我们的家，我们有责任照顾它为我们自己和后代。幸运的是，越来越多的人已经意识到这些问题。已采取措施来对付这些问题的政府。法律已经通过了停止污染。我希望这个问题将得到解决在不久的将来，我们的家园会越来越好

与环境和谐的是，我们生活在地球上，谁是自然的儿子，不仅自然人作为征服者，我们都知道，只有一个地球和地球上山脉的动物。人类细胞植物，如果它损坏，销毁性质组织，以消灭人类。因此，必须在环境与社会伦理，品德教育和实践行为的重要组成部分它。每个人都必须履行其责任和义务来保护环境。

Although people are now said to protect animals, but there are a lot of people wrong-headed, continue to hunt animals, cause many animals to the road to extinction. Humans and animals to see, sold at the same time, made from animal skins coat... But these people ever think, if you are an animal, are hunted by humans, what would you think? Some people say: "Im not a animal." But now hunted animals, animals would like to have? No, never. Although some people know how to care for the animals, but they will only pretending to go to the education of others, and themselves but also damage the environment, killing animals, so enthusiastic tasting animal meat is delicious. Take the puppy around us, for instance, although not a national secondary other rare animals, but also our good partners, whether master how to use it, it still is very dedicated, but humans find dog meat is delicious, began to kill the dog.

Now, some animals have almost extinct, take the crocodile, for instance, although it is very fierce, but humans are more fierce. And in the eyes of human beings, crocodile skin can be made into the luggage, handbags, wallets, shoes and other goods. Because of some organs from animals has the prominent economic value, thus become a subject of human plunder use, become the main factor of extinct animals. So the crocodile, has now become almost extinct animals.

Animal friends, a lot of destruction of human will have serious adverse consequences, ecological environment caused by serious imbalance, so that the human living environment is destroyed. Eliminate animal, is to eliminate human oneself, if one day the animals in the world are gone, that human can survive? To protect animals, cherish this nature of every creature! Let us start from now, to protect animals, make the world a better place!

虽然人们现在都说要保护动物，但是还有很多人执迷不悟，继续猎杀动物，导致许多动物都走向了灭绝的道路。同时人类还拿动物来观赏、卖钱，用兽皮做大衣……但这些人有没有想过，如果你是一只动物，却遭到了人类的猎杀，你会怎么想?有些人说：“我又不是动物。”但是现在人类大量捕杀动物，动物会愿意吗?不，永远不会。有些人虽然知道怎样去爱护动物，可是他们只会假惺惺地去教育别人，而自己却照样破坏环境，猎杀动物，照样兴致勃勃的品尝动物鲜美的肉。就拿我们身边的小狗来说吧，虽然不是国家一二级别的珍贵动物，但也是我们身边的好伙伴，不管主人怎么使唤它，它仍然很兢兢业业，可是人类发现狗肉鲜美，就开始捕杀小狗。

现在，有些动物已经快要灭绝了，就拿鳄鱼来说吧，它虽然很凶猛，但人类更凶猛。而在人类的眼中，鳄鱼皮可以制成行李箱，手提包，钱包，鞋等物品。就是因为有些动物身上的器官具有突出的经济价值，由此成为被人类掠夺利用的对象，成为动物灭绝的主要因素。所以鳄鱼，现在已经成为快要灭绝的动物了。

朋友们，动物的大量毁灭对人类将产生严重的不良后果，造成生态环境严重不平衡，从而使人类的生存环境遭到破坏。消灭动物，就是在消灭人类自己，如果有一天世界上的动物全都消失了，那人类还能生存吗?要保护动物，珍惜这自然界里的每一个生灵吧!让我们从现在做起，保护动物，使世界变得更加美好吧!

these days， different ways are being taken to protect cultural identity。 obviously， not only is much contribution made to maintain old houses but also rules of laws associated with cultural protection are changed for the better。 some people even say that new buildings are right to be set up in the conventionalway。 i seem to be one of opponents who believe that the action can be unsuitable in our world。

one of the main reasons is that most of traditional buildings， in my nation， that offer provide few rooms can hardly hard to meet the demands for housing as increasing numbers of people pour into the city。 compared to before， today’s population has doubled and even trebled， which puts seriouspressure on housing supply。 as a result， new buildings must be substituted for old ones that have more efficient utility， even for some old buildings that have been damaged seriously。no doubts that building or maintaining traditional buildings is very essential to raise art sense and increase choices of people’s housing。 plus， these old houses are believed as very important resources to attract international visitors。 however， the proportionof traditional houses has to be under control， and otherwise the housing of citizens is badly affected。

overall， my view is that cultural identity is so preciousthat more efforts and measures should be taken but carefully。 the excellent tradition helps with deep understanding of history， and educates youths。 nevertheless a simple and recklessbehavior。 that new buildings are built in a typical way does more harm than good in the improvement of people’s being。

[关于保护传统建筑的英语作文

It is widely noted that lots of traditional culture is disappearing along with the development of technology. Many ancient architectures and traditional ways of living have been deserted. It seems that the traditional culture and craftsmanship will be replaced in this modern era.

The following reasons can account for the above phenomenon. Firstly, traditional technologies are always considered ineffective while the new sciences are always highly efficient, because modern science and technology facilitate both our daily and academic life a lot, with which we can save much money and time. Secondly, it is costly to protect the traditional culture, especially the maintenance and repair of the historical buildings.

In my opinion, although traditional culture is an ancient heritage, it couldnt keep pace with the development of society. It is the tide of history that the traditional culture and technology will no doubt be eliminated in the end.

The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.

In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.

As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.

In the last several decades, our earth has been extremely polluted, such as air pollution, water pollution, noise pollution and so on. In recent years, the extreme weather becomes more and more frequent. Winter gets colder and summer becomes hotter and it rains more frequently. All of these warn us that protecting the environment is a serious and emergent event. As our general people, we should build proper lifestyle. We should pay attention to water and light saving. When we go out, we should firstly choose the public transportation. The most important is that we must realize that we can do a lot of things to protect our environment. Its our duty to make our home better. Let’s change from ourselves.

Nowadays, there are more and more students becoming short-sighted. Some students get short-sightedness when they are little. There are fifteen students wearing glasses in my class. Being short-sighted is common among students, even in primary school. That is too serious. Therefore, we should protect our eyes carefully. When we are reading and writing, we should keep a standard posture. Besides, we should not watch TV or play computer for too long. They are bad for our eyes. And, we should do eyes exercises regularly. A good rest is also important to our eyes. In all, eyes are the windows of our mind. We should keep it healthy.
