To protect the environment, as early as in "no desiccation jersey have fish, deforestation and hunting," the old adage. Today, we should know how to protect the environment is to protect ourselves, we not only use resources rationally, whenever they better protect the environment, let environment eternal youth, always service for our human survival and development, as a student, is now mainly to create a green campus.

Have a period of time, the campus of debris-brick everywhere, forget to turn off the faucet spouted flow a... Corridor between, not to mention the, everyone has experience, after the sweeping, turn round and then will find that the ground has been some people into different ornament, these things often let me hanging with ancient, these cases often let me deadly serious today, the campus is a small society, students in the campus of a management system cannot achieve good care environment, out of the campus into society, the environment, and how? Thats more dare not imagine.

The classmates, save our earth! You should immediately take action, starts from the minor matter, starts from now, start from the care for the campus environment. We picked up a piece of paper, a drop of water, we save, a heap of rubbish, we clean the, we love a tree seedlings, a frog, a blade of grass, plant a tree, the environmental protection as own duty, use own practical action to protect the environment, to create a green campus.

保护环境，早在“不涸泽有鱼，不焚林而猎”的古训。在今天，我们更应懂得保护环境就是保护我们自己，我们不仅合理利用资源，更竭心尽力保护环境，让环境永葆青春，永远为我们人类的生存发展服务，作为学生，现在主要是创建绿色校园。

得有段时间，校园里果皮纸屑随处可见，忘关掉的水龙头哗哗地流着……楼道间，就更不用说了，大家是有亲身体验的，扫完后，转身就会发现地面已被有些人点缀成另一番景象，这些事情常让我吊怀远古，这些情况常让我警言今日，校园就是个小社会，同学们在有管理制度的校园中都不能做到爱护环境，走出校园，进入社会这一大环境，又能怎样呢?那就更不敢设想了。

同学们，救救咱们的地球吧!大家应立即行动起来，从小事做起，从现在做起，从爱护校园环境做起。一片纸，我们捡起，一滴水，我们节约，一堆垃圾，我们打扫，我们爱一棵苗，保一只蛙，种一根草，栽一棵树，把保护环境作为自己应尽的义务，用自己的实际行动保护环境，创建绿色校园。

Each year, people burn or cut down 143,000 square kilometers (55,000 square miles) of the forest. People who burn or cut down trees do it for different reasons: farmers cut down trees in order to get more fertilize lands to grow rice or vegetables, and use the woods as fuel. Timber companies cut down trees and turn them into furniture or paper productions. As to goal miners, they remove the forests to find out whether there are goal underground.

每一年，人们都会砍伐14.3万平方千米的森林(约5.5万平方英里)。人们砍伐树木出于种种原因：农民们为了得到更肥沃的空地来种植大米蔬菜，砍下的树木用来取火。木材公司用树木来制作家具或是各类纸制品。至于那些开采煤矿的人，把树木砍掉就是为了检测是否有煤矿在下面。

However, many of us fail to realize that forests are the lungs of the earth. When we cut down trees, we also push ourselves in to a dangerous situation. That is the global warming. When you come to think about it, there are only few ways to solve these negative effects: stop cutting down trees blindly; try to find some clear energy that can replace oil and coal. But these solutions can be impractical to some degreed.

然而，我们中的许多人都没有意识到树木等同于地球的“肺部”。当我们砍伐树木时，我们就把自己推入一个危险的境地——会引起全球气候变暖。想到这些，只有为数不多的几个办法可以解决这个问题：停止盲目地砍伐树木;寻找可以代替石油和煤矿的新能源。但是，就目前来看，这几个策略并不可行。

Why trees can be so important to the whole nature? First of all, trees are the habitat of many animals. When we cut down trees, we not only destroy animals’ habitats but also ourselves. We just gradually destroy natural links. The result is that many spices of animals and plants are dying out. Secondly, cutting down trees cause global warming, to some degree. Naturalists compare forest to human’s lungs. The forests absorb the carbon dioxide and other gas that cause global warming, and then give off the oxygen that good for the human beings and other living creatures. It’s refreshed the air as well as reduced the noise. If the air quality is bad, people may die from cancers, or the new diseases for which they have no immunity. Forests also play an important role in the prevention of natural disasters. Warmer temperatures cause water to expand and also create more water by melting polar ice caps. That’s to say, the nations which near the ocean may have been flooded by the water. But the forests can prevent water loss and soil erosion, and cool off the global temperatures. It’s the key to keep the balance of the nature.

为什么树木对整个生态环境都如此重要呢?首先，树木是小动物们的家园。当我们砍伐树木时，我们不仅仅毁掉了它们的家，也毁掉了自己的。一步步的，我们慢慢分解了整个生态链，所造成的结果就是大批的动植物种类灭绝。其二，砍伐树木在某种程度上造成全球变暖。生态学家把森林比作人类的肺。森林能够吸收二氧化碳和其他引起气候变暖的温室气体，然后转化成氧气供地球上的生物呼吸。树木不仅能净化空气，也能减少噪音。如果空气质量下降，那么人们就有可能死于肺癌，或者是其他致命菌。森林在预防疾病的过程中起到了重要的角色。气温的上升导致北极的冰层融化，水平面上升。也就是说，临海的城市也许会被海水淹没。但是森林就能够阻止水土流失，使气温下降。它是保证全球生态平衡的关键。

Sometimes people only care about money making; they don’t care about the price we pay for the pollution. When the disaster is around the corner, we may be afraid and frustrated. The earth, on which our economies have always been based, is suddenly threatening our existence. All we hope that is this overpopulated, over industrialized planet can carry on for a longer time. And maybe, it’s time for us to realize that we should protect the earth, stop cutting down trees blindly and madly.

有时候人们只关心挣钱，却对我们所付出的代价不管不问。当灾难来临时，我们会害怕、会彷徨。我们赖以生存的地球，却突然变成了威胁我们生命的东西。我们只希望，在这个人口过度、工业过度的星球能继续撑下去。也许，是时候我们应该保护地球，停止盲目疯狂地砍伐树木了。

动物是我们人类的好朋友，我们不能伤害它们，但有些人却为了自已的利益，不顾那些可怜的小动物的生命，去践踏它们，捕杀它们。

记得那是今年暑假的一天，我和姥姥在公路的一边坐着聊天，我看见一只小猫想穿过马路去吃对面的一块肉，谁知，小猫刚走到马路中间，一辆大卡车过来了，司机先生一边按喇叭，一边嘴里骂道：“死猫走开。”小猫还没理解了司机的意思，司机先生已不耐烦了，他一踩油门，一个小生命就这样死在了满载货物的大卡车的车轮下。我看着这一幕又气愤又伤心，为了纪念这只可怜的小猫，所以我想把这一天——7月2日设立为保护动物节。

到了每年的这一天，人们都要为保护动物做贡献，要让小动物轻松愉快地度过这一天，不能让它们受到伤害，小动物不管到了谁家，人们都要热情招待它们，最后，我们还要用各种不同的方式去宣传小动物对人类的帮助。让世界上的每一个人都要保护小动物。

Water is one of the most valuable resource in the world, is the ideal liquid to sustain life. Mammals in vivo is between 60% and 65% water, two-thirds of the human body weight, 99% of the brain, bones are about 44% water. Lack of water, the human and the earth will not survive, forests will disappear, the plant will perish, the earth will appear the boundless desert, signs of life will disappear.

Currently the worlds fresh water accounts for only 2.5% of the total water resources, of which more than 70% is frozen in the arctic and Antarctic ice sheets, and it is difficult to use the snow on the mountain glaciers and permafrost, 87% of the fresh water resources is difficult to use. Humans really able to take advantage of the freshwater resources is part of the rivers and lakes, and groundwater, accounts for about 0.26% of the earths water.

Given the global freshwater resources shortage, not only will soon fall into the predicament of the water shortage in many countries, economic development will be limited, on January 18, 1993, the 47th United Nations general assembly resolution, determine the annual March 22 as "world water day". After the water act of the Peoples Republic of China promulgated in 1988, the ministry of water resources is to determine the annual July 1 to 7 as "Chinas water week", considering the "world water day" and "China water week" the purpose and content of basic same, therefore, starting from 1994, change the time of "Chinas water week" to the annual March 22 to 28, time coincidence, make a campaign more highlights the theme of "world water day".

水是世界上最宝贵的一种资源，也是维持生命的理想液体。哺乳动物体内60%至65%是水，人类体重的2/3、大脑的99%、骨骼的44%也都是水。缺了水，人类和地球将不能存活，森林将不复存在，植物将灭亡，地球上将出现无边的沙漠，生命的迹象将消失。

目前全世界的淡水资源仅占其总水量的2.5%，其中70%以上被冻结在南极和北极的冰盖中，加上难以利用的高山冰川和永冻积雪，有87%的淡水资源难以利用。人类真正能够利用的淡水资源是江河湖泊和地下水中的一部分，约占地球总水量的0.26%。

鉴于全球淡水资源不仅短缺、许多国家将很快陷入缺水的困境，经济发展将受到限制，1993年1月18日，第47届联合国大会作出决议，确定每年的3月22日为“世界水日”。1988年《中华人民共和国水法》颁布后，水利部即确定每年的7月1日至7日为“中国水周”，考虑到“世界水日”与“中国水周”的主旨和内容基本相同，故从1994年开始，把“中国水周”的时间改为每年的3月22日至28日，时间重合，使宣传活动更加突出“世界水日”的主题。

假如我们的生活中没有了动物，世界就会变得很孤独。我们要保护动物，从自身做起：少吃肉类食品，少穿皮衣毛衣;看见别人欺负动物，要勇敢地站出来劝说他们。

保护动物，人人有责!

What Can We Do for the Environment

Hello,everyone. Im Li Hua. Its nice to speak about what we can do for the environment,and 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 in stead 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 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.

Thank you for your listening!

你好，每个人都。我是李华。很高兴谈论我们能为环境做些什么，我想我们每个人都可以做一点点来帮助解决这个问题。

我们能做的第一件事就是在用布袋代替塑料袋，当我们去购物。它有助于保护环境。我们能做的第二件事是尽可能重复使用旧课本可以。我们也应该永远不会忘记关灯，当我们离开教室时，为了节省能源。更重要的是，它会更好，如果我们步行或骑自行车上学。我们应该尽最大努力减少污染和浪费。

事实上，即使是最简单的日常活动也能对环境产生很大的差异。我相信我们可以让世界变得更美好的生活。

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.

Protecting the Environment

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.

在过去的几十年里，我们的地球已经极度污染，比如大气污染，水污染以及噪音污染等等。近几年，极地气候越来越频繁。冬天越来越暖，夏天越来越热，还经常下雨。所有的这些都警示我们保护环境是一件严肃紧迫的事。作为普通老百姓，我们应该形成合适的生活方式。我们应该注意节约水电。出门的时候我们应该首选公共交通。最重要的是我们必须意识到我们可以做很多事情来保护我们的环境。使我们的家园变得更美好是我们的责任。让我们从自己开始改变。

In recent years, drought has prevailed in northern parts of our country. There is no or only little rain in spring and summer in the noth and northeast of China. The same is true of snow in winter.

Consequently, big cities such as Beijing and Tianjin are short of water every year, which affects the life of the urban people and the production of factories. And the drought is most felt by crops in rural areas, of course. It is said the drought has much to do with the "green house effect" and the "greenhouse effect" is caused by the pollution of the atmosphere. In the final analysis, it is brought about by ourselves.

Faced with the terrible drought, we should stop polluting the air right away. We should try all means to decrease the amount of poisonous gases which our factories and cars give off. Besides, we should take measures to protect the forests and plant as many trees as possible.

[节约用水的中学生英语作文

水是生命之源，我们要保护水资源，如果没有水，树木不能生长，花草不能开放，生命会停止呼吸，地球也会变成一个枯黄衰竭的星球。所以，我们要保护好这珍贵的生命之源。

以前，我一直不懂得好好珍惜水，常常浪费水，打开水龙头忘记关。可是一件小事后，让我懂得了要珍惜、保护水资源。那是一天夏日的午后，我和小伙伴们在草地上做游戏，突然，我脑子里灵光一闪：我们可以玩水枪大战。想到这儿，我就和伙伴们各自回家去取水枪，我的水枪容量很大，而且水还没有灌满。我就开始往水枪里注水，水注好后，我忘记关水龙头，就跑出了家门，玩了一阵子后，正好我的妈妈回来了，妈妈看见了我家的水龙头没关后，就一把将我拽进了家门，语重心长地对我说：“水是生命之源，如今我国已被列入缺水国家，许多灾区的孩子们都喝不上水，我国如今只能靠风力和一些设置才能喝上水，可你却在这里浪费水源，这不是在破坏人类自身的生命之源吗?”听了妈妈的话，我惭愧地低下了头，我决定：以后决对不再浪费水，浪费自己的“生命之源”了。

人类啊，水是生命之源，但却不是取之不尽，用之不竭的，我们要好好保护它，不能浪费水，保护人类赖以生存的资源!

On Sunday, I find to my good friend small good, each with a plastic bag, pick up the trash in the river one by one to light, our hands are full of bags, is really "to eat"! Even if we pick up the trash in the river, but you cant stop the garbage in the river, get off there will be, how to do? The most critical or arouse peoples environmental consciousness, we took a plank on the plate is greatly write: please protect the environment, starts from me. We put it in the river, in a prominent place in the task is complete, we are pleased to go home.

In order to protect our own home, in order to protect our own life, for the sake of our own future, in order to our beautiful environment, make the sky bluer, the water cleaner, let mother earth more lovely and more vibrant, let us open hands, a love, out of a force, creating a green environment.

随着人们生活水平的提高，人们越来越不重视保护环境，随地扔垃圾，随地吐痰。

每当我看到地上的垃圾，我就会感慨万千，保护环境，从我做起。就拿我家附近的一条小河来说吧，以前，河里的水十分清澈，像一块明亮的大镜子，可以清清楚楚地看到河底的许多石头;可以看到小鱼在河里自由自在在游来游去。经常有许多小朋友在河里嬉戏、玩水;大人们在河里洗菜，洗衣服。渐渐的，人们于是把垃圾扔到河里，污水排放到河里，使河水变得又臭又脏，再也不能清澈见底，变成了浑浊不清的垃圾箱。严重污染环境，严重危害了人们的身体健康。对，只有树立保护环境的观念，才有美好的明天。

星期天，我找来我的好朋友小好，每人拿一个塑料袋，把河边的垃圾一一捡光了，我们手里都是满满的一塑料袋，真是“满载而归”啊!即使我们把河边的垃圾捡光了，但是河里的垃圾是阻止不了，捞掉了还会有，怎么办好呢?最关键的还是唤起人们的环保意识，我们找来一块木板在板上大大地写上：请保护环境，从我做起。我们把它放在河边最显眼的地方，任务完成，我们高兴地回家了。

为了保护我们自己的家园，为了保护我们自己的生命，为了我们自己的将来，为了我们美好的环境，让蓝天更蓝，让清水更清，让地球妈妈更可爱，更生机勃勃，让我们张开小手，献一份爱，出一份力，共创绿色的环境。

看看新闻上那干瘪的土地，看看那一年才能洗一次澡的少水地区，看看这大千世界的种种，假如世界上只剩下一条河流，人们还能存活多久?疯狂的想象：

到那时候，人们应该像古时候赶集一样，到那条世上仅存的河流两岸，手里拿着锅碗瓢盆疯狂的强夺着这世界上唯一一条，或许还是肮脏不堪的河水……人们纷纷在这安家。渐渐地，闻讯而来的人越来越多。河旁变成了一个繁华的小镇。可是好景不长，这条河超负荷的负担也使它干涸了……最终，唯一的河流也消失了……

面对这不敢想象的画面，还有几个人能做的住，让我们一起保护水资源，节约用水，要可知道我们中国每人每天节约一滴水，就是14亿滴水，也就是1400升水，那么一年可以节约474500升水，它可以让一片荒原变成绿地。多么触目惊心的一个数字啊，我们怎能任意地浪费每一滴水呢?生活中浪费水的现象比比皆是，如洗澡涂肥皂时不关水龙头;自来水管发生漏水或爆管未得到及时修理;用过量水洗车，洗车水未循环使用;随意开启消防龙头用水;老式便器水箱容量过大;洗衣服时不用手搓而只用洗衣机;用自来水冲洗道路;在公共浴室洗完澡后“人离水未关”;解冻海鲜使用“自来水常流法”。水呀，在人们的手指逢间悄悄流走了。如果说，没拧紧水龙头下次可以注意，那么往淡水河里扔垃圾该如何弥补呢?家里离河道近的朋友有时为了图省事，趁大家不注意时，以迅雷不及掩耳之势将手中的垃圾扔进清澈的河水中，河水受到污染，开始变色、变臭，那本可得到使用的水就这样被浪费了。大家只是一味的抱怨：怎么那么臭?但大家可曾想过这一切竟是自己造成的，大家不应该在此抱怨，而是应为自己的恶行而感到自责、悔恨。

现在，中国的资源已经开始减少了：中国水资源初步估算为27115亿立方米，河流山川多年平均径流相当于世界径流总量的5.8%，而人均资源占有量很低。中国各项自然资源的绝对数量看均甚可观，但人均占有量都低于世界平均水平。我们应该怎样去珍惜资源呢?

珍惜资源，是人人都应该做到的。有多少人在珍惜资源呢?非常多，但是还有更很多人在浪费资源。为什么我们不能做到呢?我们可以做到，只是我们需要增加环保意识。珍惜资源，保护环境，我们完全可以从身边的小事做起，比如说：不乱扔垃圾，注意节约水和电资源，不使用一次性物品等，这些全都是珍惜资源的方式。只要我们有毅力，就一定会当上珍惜资源的小标兵。

Environmental protection is a big project, but we can start from around things, do a lot of things to protect the environment.

Our paper every day, do you know the paper is how to? Is made of trees to make paper. Every year around the world to cut down many trees to make paper. I have seen a special TV, save 1500 sheets of paper, you can leave a big tree. The tree is our good friend, it can turn carbon dioxide into oxygen, can reduce the noise, can block the sand, can prevent water loss and soil erosion... Starts from me, saving every piece of paper, children all over the world can save a lot of a lot of paper, you can retain a lot of trees, you can leave a big forest, desert, less and less, more and more pure and fresh air, green more and more. How I wish my hometown mountain more green, and blue, the water environment of our lives forever charactizing a fine spring day.

We used in battery life; it contains lead, if throw it carelessly, section 1 waste batteries can lose one square metre of soil utilization value forever. In many countries, many areas have carried out recycling of waste batteries. In Germany, to buy a new battery, used batteries must be pay back. So, we should to find a "home" for waste batteries. I hope we panzhihua environmental protection departments also set up waste battery recycling. Thoroughly protect the soil so that it can always grow crops.

Save a piece of paper, recycling waste battery section... Although we do is small, but it made great contribution for environmental protection. I hope my classmates from now on, all to do an environmental small guards. There is only one earth, we have to take care of it.

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。

On National Day last year,mom and I saw a dog on the roadside.It was thin and poor.It was looking at us for help.It was shaking in the wind.This made me heartached.I asked my mother if I could take it home?My mother said yes.We went home with the dog.We cleaned his body and fur.From then,it has been our family members.Sometimes I got angry at him,but he was running around me to jump.When my parents got home from work,he will go downstairs or stand in the doorway looking at them and meet them.He will use eyes to communicate with us.In the morning,my little alarm clock rang,he would chop my bedside,he didnt stop until I woke up.So I was never late.
