现在，地球环境持续恶化，给人们带来了许多灾难，这一切都来自人们的污染。想要让她减少污染，只有环保。

生活里，环保随处可见，比如：节约水资源，少用塑料袋，利用太阳能、水力发电。宣传环保的人也多了，有说地球在哭泣，请保护环境的;也有说保护环境，人人有责的，各种各样，五花八门。但也有人不爱惜地球，依旧我行我素：浪费纸张，浪费水资源，开汽车。

一次，我在街头看见一个人在抽烟，抽完后连烟头也不灭，直接扔在了地上。接着，他又开始吃瓜子，吃完的壳随便一吐。我实在看不下去，就对他说：“怎么能这样呢?”他说：“一个小孩子，懂什么呀，走开。我没有害怕，对他说：“我虽然小，但也知道这样不对，何况你大人!而且你还直接把烟头扔在地上，万一现在天气干燥，引起火灾怎么办。”停了停，说，“还有瓜子壳，人家看了怎么想啊，你这是在影响环境。”那人低下头，没有说话，我想他会改正的。

还有一次，我到堂弟家做客，看见他洗手时把水开得很大，洗完手后他还用很多纸擦手。我看了后对他说：“你怎么这么浪费呀?”他听后，撅着嘴对我说：“就这么一点，又没什么关系!”我生气地说：“这怎么会没关系呢?你知不知道那些贫困山区的孩子们一天只喝多少水?知不知道他们只有多少纸?”可我那不服输的堂弟却理直气壮地说：“不知道!”我叹了口气说：“我们比他们要幸福多了，你怎么不知道知足呢?”这时，堂弟知道了事情的“重要性”，低着头说：“我知道错了，我会改正的。”

让我们从我做起，保护我们唯一的大家园吧!

Economic development and environmental protection are a pressing issue primarily for developing countries where, in trying to catch up with developed countries, they have to consume natural resources on an unprecedented scale. This has seriously polluted our environment and, with the global environmental campaign gaining momentum, many people in China call for the precedence of environmental protection over economic development.

Any attempt to pose economic development and environmental protection as diametrically contradictory is simple-minded. Since no country is willing to stop its economic development, the best way is to strike a balance between the two and to heighten the environmental awareness of those solely concerned with economic development.

European countries both economically developed and environmentally friendly can serve as perfect examples for China. Their success story in both undertakings illustrates that environmental protection does not mean a complete standstill of economic activities or exploitation of natural resources, but rather an active development and application of effective technologies to minimize environmental consequences. In Germany, environmental protection has become part of economic development as it boasts the world s most successful environmental industry. With a developed economy, we are well equipped to develop sophisticated technologies that can effectively safeguard our environment.

Many wild animals are facing the danger of extinction， because the environment that they are living in has changed greatly。 For example， with the developmet of cities， the using of insecticide and serious pollution， their living areas have become narrowcr and narrower。 Many of the wild animals， now are confronted with food crisis。 At the same time， man is killing off species just for getting their fur， skin， horns， teeth and meat。

In order to protect our resources of ecology， people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty。 There fore， measures of the following should be taken： pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life， reserves。

Only if we human beings take some drastic measures can wild animals be preserved。

With the continuous development of science and technology, the increasing number of cars, emissions of emissions has caused serious pollution, perhaps, a few years later generations, hundreds of years after everyone, perhaps because of air pollution and death. Now, twenty percent of the people on earth every year are killed by drinking contaminated water, and if this continues, will the earth become bare after tens of thousands of years, like the moon?

According to the statistics of scientists, every year, more than 20 percent of the trees are withered by exhaust pollution every year. More than eighty percent of our useful bacteria die, and everyone may feel very exaggerated, but it is true. Followed by contaminated waste water, waste gas and so on. Is human error?

How much I hope that we can cherish every thing around us, every animal, every beneficial bacteria, because it is possible, in tens of thousands of years later today, they are gone.

Animals have warned against humans;

Bacteria have warned against humans;

Every innocent life warned us.

"Human, do not harm yourself, do not kill us again!"

随着科技的不断发展，汽车的不断增多，排放的废气已经造成了严重的污染，或许，几年后的子孙后代、几百年后的大家，或许会因为大气污染而死亡。现在，地球上每一年都有百分之二十的人因为饮用了受到污染的水而死亡，如果这样延续下去，地球在几万年后岂不是变得光秃秃、像月球一样了?

据科学家的统计，每一年，每一月都有百分之二十多的树木因为废气污染而枯萎。百分之八十多对我们有益的细菌死亡，大家或许会觉得很夸张，但这是事实。其次还有受到污染的废水、废气等。人类有错吗?

我多么希望大家能珍惜我们身边的每一个事物，每一只动物，每一只有益的细菌，因为，很有可能，在几万年后的今天，他们都没有了。

动物对人类发起了警告;

细菌对人类发起了警告;

每一条无辜的生命对我们发起了警告。

“人类，不要再害你自己，不要再害死我们了吧!”

In fact, there are many things that can seriously pollute the environment: litter, spitting, grass and so on. The consequences are severe. But the waste of resources cannot be ignored. The worst is the waste of water.

At present, the reform and development of our country is at a critical juncture, and we should strive to achieve the goal of building a moderately prosperous society in all respects. But there are still some problems -- our living environment is seriously polluted; And the green resources are falling.

We do a lot of what the environment, such as: on one occasion, in a clean small garden, there have been some rubbish, gradually where there are a lot of people throw garbage, there is a garbage dump. It turned out that the trees were green and the flowers and grass were blooming. The bees and the butterflies were there, and there was a smell of enchantment. But now, there was nothing to do with it, and the smell of it was so bad that no one was willing to stay there any longer. Alas! It is a pity that such a beautiful garden is gone. If people notice that they dont pollute the environment, now, by the way, its a kind of escape. And, what a wonderful thing for people to have a rest and take advantage of the cold. But now its a junkyard, and the consequences of polluting the environment are terrible.

And there are a lot of factory waste is also pollute the environment, but the most serious is the pollution of water, I heard of such a story: there was a village, there was a clear pool. There were lotus flowers in the water and the goldfish, and it was so beautiful that visitors to the village would not forget to take a look at the scene. And people in the village wash and cook and drink water and water, so the water is very precious. One day, a businessman opened a factory near the pond, and the factory shut down a lot of waste water and garbage and went into the pond... The result can be imagined: the goldfish died, the water side became the sewage, the tourists no longer came, the people in the village moved away... Alas! The little pond has disappeared. The factory severely polluted the environment and made the environment in the village very bad and affected peoples lives. Its a story, but there are a lot of these things in everyday life, and the results are very serious, not just simple consequences.

In fact, there are many things that can seriously pollute the environment: litter, spitting, grass and so on. The consequences are severe. But the waste of resources cannot be ignored. The worst is the waste of water.

Now, Beijing is a city of severe water shortages, but there are a lot of people in the waste water, such as: there are a lot of people out of the water to wash the dishes and laundry water and reuse. In fact, although can only save a little water, economy is a lot of!

Also, people who sell fish in the market love to put a faucet on the side of the water, and when they use water, they will let the water flow freely. How much water they would waste if they went on like this!

The drink, the wine, etc., are now made with water. Some factories use a lot of water, so some of the water is wasted. Thats a lot of wasted water. This water can do a lot if you save it! You can also avoid a little water.

What Can We Do for the Environment

our environment is becoming worse and worse，what can we do for the environment?I think each of us can do a little bit to help with this problem。

The first thing we can do is to use cloth bags instead of plastic bags when we go shopping. It helps to protect the environment. The second thing we can do is to reuse the old textbooks as possible as we can. We should also never forget to turn off the lights when we leave the classrooms in order to save energy. Whats more，it would be better if we walk or ride a bike to school. We should try our best to reduce pollution and waste。

In fact，even the simplest everyday activities can make a real difference to the environment. I believe we can make the world a better place to live in.

In modern society, we tend to become more and more aware of our living environment or physical environment, because we are not clean as before. So many people now choose their house as to its environment but not its location and expenses to afford it. As we all know, the environment pollution is more and more serious during these years, what we could do is to make great efforts in protecting environment gradually. As to government pollution, as to common people. We also try to protect it and make it remain clean. Although we have managed to protect the environment to a certain extent. It is still a very long way to go.

Protect our enviorment The earth is our home,we must take care of it.We shoule make a less pollution as we know everybody in north America makes 1000 kilograms of the garbage everyday. Most of it is packaging Most of garbage turns into soil but not to plastic,plastic keeps for many years it will pollute our environment so we shouldn’t waste thing we should make some things for recycling .

在现代社会中,我们往往更加了解我们的居住环境还是自然环境因为我们不干净如故.现在这么多人选择它作为自己的房子,而不是它的位置和环境费用负担.众所周知,环境污染日趋严重,这些年来,我们可以做的是努力保护环境,逐步实现.至于政府的污染,为百姓.我们也设法保护它,使之保持清洁.虽然我们已能在一定程度上保护环境.它还有很长一段路要走.

保护我们的环境 地球是我们的家园,我们必须照顾好它我们应该使减少污染,如我们所知大家在北美的垃圾进行1000公斤。大多数都是包装大部分垃圾变成土而不是塑料制品,塑料保持多年来它会污染我们的环境,所以我们不应该浪费我们应当做些事情回收利用。

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 bees 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?

早晨，我背着书包走进校园。

Morning, I entered the school with a bag.

路两旁的花坛里，苍翠的青松，墨绿的冬青，在寒风中左右摇摆。

Road on both sides of the border, the green pine, green holly, in the cold wind sway.

这时，一位叔叔正要把抽完的烟蒂扔向花坛，我急忙赶过去说："叔叔，请爱护环境，不要随地乱扔烟蒂。"

At this time, an uncle was about to finish the cigarette butts into flower beds, I hurried over to say: "uncle, please take good care of the environment, do not throw cigarette butts. Tofu vegetables salted meat. Chopsticks are ready, so is the soup.

叔叔看着我不好意思地笑了，说："对不起，小朋友。"说完，他主动把烟蒂掐灭，送到垃圾箱里。

Uncle looked at me and smiled sheepishly and said: "Im sorry, kids. "Finished, he took the initiative to put out cigarette butts, sent to the dustbin.

我高兴地说："谢谢你，叔叔。"

I am happy to say: "thank you, uncle. Tofu vegetables salted meat. Chopsticks are ready, so is the soup.

叔叔也笑着夸我："你真是一个爱护环境的小卫士。"

Uncle smiled and said I: "you really are a guardian to protect the environment. Tofu vegetables salted meat. Chopsticks are ready, so is the soup.

Good environment can make people feel happy and fit 。 To improve the environment means to improve our life。

We should plant more trees and flowers around us 。 We shouldn’t cut them down 。 We should stop factories from pouring waste water into the river and waste gas into the air。

Whenever we see litter on the ground ， we should pick it up and throw it into dusbins。 Never spit in public。 Don’t draw on public walls。 It’s our duty to protect the environment。

一望无垠的大海给人期盼，给人美感，给人温暖的母爱。

大海像一首诗，灵动跳跃;像一幅画，意蕴丰富;又像一支交响乐，浩瀚澎湃......它时而平静，犹如一面明镜;时而暴怒，涌起万丈狂澜，能掀翻航行着的小船。在我心目中，大海是蓝色的世界，也是生命的摇篮。孕育着许许多多自由自在的小生命。大海是那样的神秘，那样的迷人!

如今，大海变了样。海水不再清澈，它变浊了，变脏了。海水冲上沙滩，留下的不再是活蹦乱跳的小鱼小虾，取而代之的是一堆又一堆的垃圾，还夹杂着不少惨死的小鱼小虾，散发着阵阵恶臭。这是为什么呢?这都是由于我们人类。有人在海边欣赏美景时，顺手把恶臭的垃圾扔进海里。也有在海边居住的人把厕所的排泄管直通到海底。更可恶的是工厂排放的废水大股大股地流进海里，把海水染成了一种奇异的颜色。导致生出了许多缺少脑子`智商低的婴儿，我们的下一代-眼睛明亮`嗓音稚嫩`脸峡透红的下一代将永远见不到美丽迷人的蓝色海洋了。

有人曾做过一个实验，他把一盆清水比做大海，再把一滴墨水滴入"大海"中。顿时，墨水慢慢地散开、变浅、消失，"海水"几乎和原来一样干净;如果墨水一直不断滴下去，"海水的颜色就会越来越深，最后变成一盆黑水。地球上60亿人口每天生产出大量生活废水和工业污染，就像墨水一样一直注入原本清澈的海水中经快变成，现在的大海已一潭污水了。

为了我们人类的身体健康，为了我们的子孙后代看到美丽迷人的蓝色海洋。让我们立刻行动起来吧，像热爱生命那样热爱海洋，热爱这人类共同的蓝色家园。

海水盐度如果我们分析海水的盐度，会发现地区间只有轻微的变化，然而有些小的变化是重要的。

导致海洋的盐度变化的基本过程有三个，其中之一是通过蒸发的方式即把液态水转化为水蒸气来减少海洋中的水分。

这样由于盐留了下来，所以盐度增大。

当然，如果这种方式走向极端，将会余下白色的盐晶体。与蒸发相反的是降水，如降雨，由此水被加入海中，海水被稀释，从而盐度降低。

这种情形会发生在大量降雨的地区，或江河入海岸处。因此，盐度通过蒸发减少水分而上升或通过降水或径流增加淡水成分而下降。一般来说，在阳光很

强烈的热带地区，海水的盐度略高于世界上其它没有热带那样多的蒸发的地区。同理，在江河稀释海水的海岸地带，海水盐度略低于其它海区。

第三个可以变更盐度的过程与海洋中冰的形成和融化有关。海水冻结时，溶于其中的物质被留了下来。这样，在新形成的海

水冰面的正下方的海水比在冰形成之前有更高的盐度。

当然，当冰融化的时候，会降低周围水中的盐度。

在南极洲边缘的威德尔海中，结冰过程增加低温海水的盐度，从而形成了浓度最大的海水。这些大密度的海水下沉，可以在世界海洋的深水域发现。

if the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. nevertheless, some of these small changes are important. there are three basic processes that cause a change in oceanic salinity. one of these is the subtraction of water from the ocean by means of evaporation--- conversion of liquid water to water vapor. in this manner the salinity is increased, since the salts stay behind. if this is carried to the etreme, of course, white crystals of salt would be left behind.

the opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. here the ocean is being diluted so that the salinity is decreased. this may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.a third process by which salinity may be altered is associated with the formation and melting of sea ice. when sea water is frozen, the dissolved materials are left behind. in this manner, sea water directly materials are left behind.

in this manner, sea water directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.in the weddell sea antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water. this heavy water sinks and is found in the deeper portions of the oceans of the world.

在四野飘香的花丛中，我和蝶儿一起嬉戏、欢笑;在郁郁葱葱的森林里，我与小鸟一起追逐、歌唱;清晨，我迈着轻盈的步履去原野上踏青，雾霭缭绕着、白纱般的柔柔地漂浮在空中。吮吸着花草的芳香， 欣享着阳光的沐浴，我被陶醉在这如痴如醉的梦幻里;夜晚，我坐在稻谷飘香的农家小院里，仰望着璀璨的星空，聆听着蝉鸣嘹响，蛙声如潮，仿佛置身于一个童话般的王国。

In the fields the fragrance of flowers, butterflies, and I play together in laughter; a wild profusion of vegetation in the forest, I chase, with birds singing; early in the morning, I walked with light steps to the fields on the outing, mist shrouded with white veil, gently floating in the air. At the scent of flowers and plants, we enjoy the sun bath, I was intoxicated in the dream of the night, delude one to folly; I sat in the fragrance of rice farmers in a small courtyard, looking up at the bright sky, listening to the sound of cicadas Liao ring, frog sound waves, like being in a fairy tale kingdom.

保护环境与维护生态平衡的历史重任要落到我们跨世纪一代的肩上。让我们都来关爱自然，热爱地球吧，手挽手、肩并肩、心连心地铸起一道绿色环保的大堤，捍卫资源、捍卫环境、捍卫地球、捍卫我们美好的家园吧!

The historical responsibility Protect environment and maintaining ecological balance to fall on our cross century generation shoulder. Let us all come to love nature, love the earth, hand in hand, shoulder to shoulder, heart to heart to set up a green dam, defend, defend, defend the earth resources and environment, protect our beautiful homeland!

Saving Water

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

节约用水

我们的世界不仅饥饿，而且因为缺水而干渴。对你来说这可能似乎奇怪：因为我们的地球表面75%由水覆盖着。但是，这巨大的数量中97%是海水、或咸水。只有剩下3%

的来自河流、湖泊、地下，和其他来源的淡水供人们饮用、使用。即使如此，这3%的水源我们也不能够完全使用，因为有些淡水是以冰山或冰河的形式存在。更糟糕的是，一些水源已遭受了污染。

然而，尽管按现状看来，这些少量的淡水即使时常转化成雨水的形式，对我们来说，也仍然够用。可是我们对水的需求却日益迅速增长。我们只有现在采取措施解决这一问

题才能避免未来世界范围内的严重水资源缺乏。限量供水会对农业和工业产生不良的影响。我们举个小小的事例就能证明水对工业的必要性。每生产一吨钢材就要消耗91，000升水，你知道吗?

我们必须杜绝对宝贵水资源的浪费。我们应该采取的第一步就是要发展水再利用的方法。该领域的实验已在进行，但是仅是小规模地进行。水资源再利用系统的重要性

对我们而言，与空间站不相上下。

In recent years, I find it easier to our resources dried up. All of these, because we have recently a lot of collection resources, leading to our mothers are dwindling.

What is the mother of all resources less and less? Is, of course, we humans excessive spoiling dont cherish, would cause such a serious result. Our earth forest area has reached 600 million hectares, the figure is due to our human previously has important sense to protect the environment, know that if you dont have a good environment, we wont be able to breathe to the light wind gently brushed the grass surface sweet taste. And now? Us that the earths forest area is still not arrived 6 hectares, this kind of situation, it is because we humans cut down trees and destroying forest without restraint, make almost fell by 1% in each of the forest area in the world, now our protection in the nature of the important consciousness is more and more shallow, dont take care of the objects around, as the forest is less, the first bite of the air we breathe is less and less fresh...

Is not destruction of forest resources, and our mineral resources. It is limited, now our production technology constantly improve, the accelerating speed and shortage of some minerals occurred, even dried up. Until then, we will always stay in the desolate landscape.

In the face of these, can see there are so many resources in we lost too much! We rely on resources too much! All around us, little drops of the resources are in decline, if lost it all, we will how to live! So, let us sincerely treat our mother earth, try to cherish, to cherish. If only use a small plastic bag, it should not be too!

Let us act, to defend the earth!

近几年来，我发现我们的资源越来越容易枯竭了。这些，都是因为我们最近大量的采集资源，才导致我们的母亲日渐枯竭。

是什么让我们这位母亲的资源越来越少了呢?当然是我们人类过度的糟蹋不珍惜，才会造成这样严重的结果的。我们的地球森林面积曾经达到了6亿公顷，这笔惊人的数字是由于我们人类以前有着保护环境的重要意识，深知如果没有了良好的环境，我们也就无法呼吸到微风轻拂过草面的甜美味道。而现在呢?我们地球的森林面积还不到了6公顷，这种状况，就是因为我们人类不加节制地砍伐树木和毁林开荒而造成的，使世界上的森林面积几乎每年减少了1%，现在我们的保护在自然的重要意识越来越浅，不爱护身边的一草一木，由于森林逐渐变少，我们呼吸的第一口空气也就越来越不清新……

还不止森林资源被破坏，还有我们的矿产资源。它是有限的，现在我们的开采技术不断提高，速度不断加快，使某些矿种发生短缺，甚至面临枯竭。到那时，我们将永远呆在荒凉的大地上。

面对这些，可以看出来我们失去的资源真是太多太多了!我们的依赖的资源也太多了!在我们身边，点点滴滴的资源都在减少，如果失去了这一切，我们将如何生活!所以，让我们真心地善待我们的地球母亲，努力去珍惜，去爱惜。哪怕只是多用一个小小的塑料袋，这也是不应该的!

让我们行动起来，保卫地球吧!
