The earth mother as the cradle of life, human like a spoiled child of the earth. She give us everything we need for life leave her, we will get nothing. Beautiful living environment is the basis of which we live, but now, our environmental protection consciousness is more and more weak. Though, we all know that protect the environment, but not the property of the consciousness of earth, destroy the originally beautiful environment; In fact, in life, as long as pay attention, everywhere can be environmental protection.

In those restaurants everywhere can see around us, the boss in order to achieve "health" standard, and unconsciously extensive use of wooden chopsticks that were made from wood; Cost is huge, hits the verdant trees with bangs fall, only the birds were forced to leave, a group of a group of lovely animals homeless again, but as they didnt see, originally natural ecological environment destroyed by them, just like that. Not only did not have the forest, and animals are not spared. Recently, some cantonese put smart cute little monkeys alive opened the brain had his head down, they looked at each cute little monkey innocent dead, but still, this is what a horrible thing!

We as the master of the earth, if you dont cherish everything now, that this beautiful environment will leave us early. At that time, we will face catastrophe, the earth will be scarred, and hurt; So we should do owners should do, well protect our survival environment, do not deliberately to destroy, remember: to protect the environment, is to protect the future of mankind.

地球母亲就像是生命的摇篮，人类就像是地球的骄子。她，给予了我们生活所需要的一切离开她，我们就一无所获。美好的生存环境是我们赖以生活的基础，可是现在，我们保护环境的意识却越来越淡薄了。虽然，大家都知道保护环境，但却不自觉的掠夺地球的财产，破坏原本美丽的环境;其实，在生活中，只要留心，处处都能环保。

在我们周围的那些餐馆中随处可以看到，老板为了达到“卫生”的标准，而不自觉的大量使用那些用树木做出的木质筷子;为此付出的代价是巨大的，一棵棵青翠的树木随着巨响而轰然倒下，一只只鸟儿被迫离开，一群又一群可爱的动物无家可归，可他们却当作没有看到，原本自然的生态环境就这样被他们破坏。不仅森林没有了，而动物也是不放过。最近，一些广东人竟然把机灵可爱的小猴子活活的把头打开把脑子吃了下去，他们看着一只只可爱的小猴子无辜的死去，却还是无动于衷，这是多么令人发指的事呀!

我们身为地球的主人，如果不珍惜现在的一切，那这美好的环境一定会早早的离开我们。到时候，我们会面临灾难，地球也会伤痕累累，而受到伤害;所以我们应该做到主人应该做的事，好好的保护我们生存的环境，不要蓄意的去破坏，要记住：保护坏境，就是保护将来的人类。

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

there are many kinds of animals in the world,but not only the humans.we live in the same world,and we should be friends.as everybody knows,the humans are the rulers of the world today,so we should protect our friends--the animals!

but how to protect them?as first,i think we must stop killing the rare birds and animals,especially the young ones.the second,we have to protect the environment,to make the sky blue,to make the grass green,to give the animals a comfortable space to live.it`s not only for the animals but also ourselves.the last,we should tell more and more people why and how to protect the animals,make everyone do this.

环保是一个很大的工程，但我们可以从身边的小事做起，为保护环境做很多事。

我们每天都要用纸，你知道纸张是怎么来的吗?是用大树来造纸的。全世界每年都要砍掉很多树来造纸。我看过一个专题电视，节约1500张纸，就可以保留一棵大树。大树是我们的好朋友，它可以把二氧化碳变为氧气，可以降低噪音，可以挡住风沙，可以防止水土流失……从我做起，节约每一张纸，全世界的小朋友可以节约很多很多纸，就可以保留很多很多大树，就可以留下一片大森林，沙漠越来越少，空气越来越清新，绿色越来越多。我多希望我的家乡山更青、水更绿，我们生活的环境永远鸟语花香。

我们生活中用到的电池，它含有铅，如果把它随手乱扔，1节废电池可以使一平方米的土壤失去永远的利用价值。很多国家、很多地区都开展了废电池的回收。在德国，购买新电池的时候，必须将废旧电池交回来。所以，我们应该给给废电池找个“家”。我希望我们攀枝花的环保部门也设立废旧电池回收站。好好的保护土壤，让它可以永远长出庄稼。

节约一张纸、回收一节废旧电池……我们做的虽然是小事，但却为环保做了大贡献。我希望我的同学们从现在开始，都来做一个环保小卫士。地球只有一个，我们都要好好爱护它。

so impressed by these works. There were also some handworks, which were so

creative, it reflected the students’ wisdom. Though we were busy with our

subjects most of the time, some students still kept on their hobbies and made it

So what should we do? Today, Ill give you some advice to protect the environment, the content is as follows:

We live earth is deteriorating rapidly, did we have to pay attention to their own living environment cause harm to nature, you must not throw sundry, especially those serious pollution of garbage, waste batteries, for example, because the section waste batteries contain heavy metals, if flow to clean the water, it is very much pollution, then try to save trees made items such as paper, pencils, because waste these things is the destruction of the forest.

Today, Dameisha took me to see the sea, because I have never seen the sea. I was thinking of the sea all the way. I saw on TV the sea is very beautiful, I feel that the sea should be like this: blue water, spray gently lying in the arms of the sea. On the beach there grows many palm beach, lying quietly in many shells, conch. A few crabs to climb. Should be against the background of blue sky, the sky the sun, seagulls flying, this beautiful picture of you! What an intoxicated! I feel relaxed and happy.

Can be when I saw the sea of a moment, I am disappointed, the mood suddenly changed. Because my eyes of the sea is dark, is muddy, is not angry, is not confident. Some just inferiority. I know that the sea is not so, but people are polluting into this.

Now, human beings in order to live, a large number of cutting trees, cut and not planted, how many of the previous tropical rain forest, now is flat, how many trees, now replaced by high-rise buildings. Factory emissions, air pollution, and no trees to release fresh air. And plant emissions of toxic wastewater, so that water in the small fish, shrimp have been poisoned, and the river afloat smelly fish dead bodies and garbage, all this is how terrible ah!

Lets go and embrace the nature! To protect nature! Let everything in the world be beautiful.

今天，大姨带我去大梅沙看大海，因为我从来没有见过大海。我一路上都在想大海的样子。我看见电视上的大海很漂亮，我觉得大海应该是这样的：碧蓝的海水，浪花轻轻的躺在大海的怀抱中。海滩上生长着许多的椰树，海边静静的躺着许多贝壳，海螺。几只螃蟹爬来爬去。映衬着的应该是蔚蓝的天空，天空上的一轮红日，海欧飞来飞去，这景象多美呀！多令人陶醉呀！我心情轻松愉快。

可当我才看见大海的一瞬间，我失望了，心情一下子变的沉重了。因为我眼前的大海是灰暗的，是浑浊的，是没有生气的，是没有自信的。有的只是自卑。我知道大海原来不是这样的，而是被人们污染成这样的。

现在，人类为了生活，大量砍伐树木，砍了又不栽，以前有多少热带雨林，现在是平地，以前多少树木，现在取而代之的是高楼大厦。工厂排放的废气，污染空气，又没有树木放出新鲜的空气。还有工厂排放出的有毒的废水，让水里的小鱼，小虾都被毒死了，河面上浮着发臭的鱼的尸体和垃圾，这一切又是多么的可怕呀！

让我们去拥抱大自然吧！去保护大自然吧！让世界上的一切都变得美好。

a country maid was walking along with a can of milk upon her head,when she fell into the following train of reflections."the money for which i shall sell this milk will enable me to increase my stock of eggs to three hundred,these eggs,allowing for what may prove addle,and what may be destroyed by vermin,will produce at least two hundred and fifty chickens.the chickens will be fit to carry to market just at the time when poultry is always dear;so that by the new year i cannot fail of having money enough to purchase a new gown.green-let me consider-yes,green becomes my complexion best .and green it shall be, in this dress i will go to the fair,where all young fellows will strive to have me for a parter;but no-i shall refuse every one of them,and with a disdainful toss turn from them."

transported with this idea,she could not forbear acting with her head the thought that passed in her mind,when down came the can of milk!and all her imaginary happiness vanished in a moment.

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.

Now, some animals have disappeared, and then take crocodile is close to extinction, though very fierce, but humans are more fierce. 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. Crocodile with sharp teeth, and huge appetite for food, we all said the crocodile, but more afraid of human, the crocodile in the eyes of human, the crocodile can be made into the luggage, handbags, wallets, shoes and other goods, 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, starts from me, to protect the animals, make the world a better place! To protect animals, is to protect human oneself.

现在，有些动物已经灭绝了，就拿快要灭绝的鳄鱼来说，虽然很凶猛，但人类更凶猛。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。鳄鱼长着锐利的牙齿，和硕大的食物胃口，我们都说鳄鱼可怕，但鳄鱼更怕人类，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，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，从我做起，保护动物，使世界变得更美好吧!保护动物，就是保护人类自己。

proud of yourself; when you fail, never give up. Please smile to face your life. If you do this, you will find the sky more blue; the sea more green….. Your life will become better and better!

One day my grandmother and I went to the park, it began to rain when we got there. Some people were disappointed, but my grandmother smiled: "it is good to rain, it will water the field, and the crops will grow better. I think so. If we can change our mind to see the things, we will discover all things are beautiful. In everyones life, the mood is very important. It can encourage unsuccessful people not to lose heart, to make sad people feel better. At last I want to say, if you enjoy life, you will be happy forever.

I have to say that music really has a strong attractiveness to me.

Naturally, everyone can choose suitable music to listen to. However, when you

find a kind of music which can bring happiness to you, you will be surprised and

become excited. Music has a magical energy, and it can help people gain good

mood in a great extent.

When you feel sad, you can have a try to listen to soothing music. At

first, soothing music will let you calm down. You will find that you will play

much attention to the music, and then your sadness can be decreased. You will

enter music ocean. You can experience a baptism of your heart. It does not

matter that when you listen to soothing music and you want to cry, you should

just follow yourself feeling to have a thorough release. Music will give you

enough encourage to overcome difficulties.

Music also can double your happiness and arouse the fighting. For instance,

when you solve some very difficult situations and gain success eventually, you

will have a great mood. At this time, exciting music will witness your success.

You will feel satisfied. Music lets you remember the glorious moment and cherish

your success. Music can give you unlimited motivation to achieve goals，because

you still want to listen to glorious music.

In addition, music includes a lot of useful knowledge. People can learn

precious knowledge from music. Because there is different music, we can find out

that different nations have different music thoughts to express. And from music,

we can listen to music culture. Music culture will give you a deeper

understanding to learn foreign culture, such as foreign language, foreign

history and foreign traditional customs and so on. In a word, music has an

important effect on promoting society development.

Music indeed has a magical power to help people and society develop. I

believe that music will still continue to bring us many surprises. As the

development of society, great music will become more important.

The animal is the friend of our human beings. We live in the same earth.

Animals and human beings can’t be separated from each other. But some animals

are getting less and less. So it’s necessary for us to protect animals,

especially wild animals. Some people kill wild animal because of money. It’s

illegal. Beside, because of the development of society, human needs more space

to live in, so we explore the forest. Animals have less space to live in. The

number of wild animals decreases year by year. It’s high time to take actions to

protect wild animals.

Dear Li Hong,

I haven’t heard from you for quite a long time. How have you been these

days?

During the coming winter vacation, I’m going to Beijing for a tour. As I

have never been to Beijing before, I’d like you to be my guide. I hope you can

show me around the Great Wall, the Summer Palace and some other places of

interest. What’s more, during my visit I hope to stay together with you in your

house so that we can have a good talk about our life and studies. What do you

think of my idea? I would like to know your opinion.

Please give my best regards(问候) to your parents.

Yours sincerely,

Many animals are in danger of dying out。 As is shown in the chart， we can see the number of animal species decreases faster and faster and this trend will continue。 From 1980 to 2010， at least 1 million animal species have disappeared。 Worse still， more and more wild animals are in great danger。 It is not a piece of sensational news; it is a fact， a harsh reality。 Unfortunately， we may not see these animals in the near future。

From the second picture， we can find some reasons。 Why is the number of animal species declining year by year？ Apparently animals have become victims of fashion industry。 Animal skin has been used to make fashionable clothes and these clothes sell at a high price。 So some greedy people begin to kill animals in a large quantity。 This irresponsible behavior not only breaks the balance of nature but also endangers the living environment of human beings。

As far as I am concerned， something must be done to stop this illegal action。 We believe "no buying， no killing"。 First， we must make concerning laws to protect these animals in danger。 Second， we must take some measures to protect animals effectively。 Animals are our friends and part of our environment。 Third， we should raise peoples awareness to protect animals and our environment。 In this way， we can build a harmonious society and ensure a sustainable development。

Everyone can do something for our environment.What Can I Do for Our Environment?

每个人都可以为我们的环境做些事情。我可以为我们的环境做些什么呢?

Everyone can do something for our environment.As a student, we should build the sense of frugality in our daily life in the school.I always turn off the lights in the classroom when I leave.Both sides of the paper can be used if it is possible.After school, I bear the consciousness of environment protection in mind.In order to protect the forest I often refuse to use the paper cups and disposable chopsticks consciously.I believe that individual contribution to the environment will build a more beautiful world.

每个人都可以为我们的环境做些事情。作为一名学生，我们应该在学校的日常生活树立节俭意识。当离开教室的时候我经常把灯关掉。如果可能的话，纸张的两面都可以利用。放学后，我时刻把环保意识牢记在脑海中。为了保护森林我经常有意识地重复利用纸杯和一次性筷子。我相信，个人对环境的贡献将建立一个更美好的世界。
