环境保护的英语作文篇三

There are still many problems of enviromental protection in recent years. One of the most serious problems is the serious pollution of air,water and soil. The polluted air does great harm to peoples health. The polluted water causes diseases and death. Whats more, vegetation has been greatly reduced with the rapid growth of modern cities.

To protect the environment,governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, government are playing the most important role in the environmental protection today.

In my opinion , to protect environment, the goernment must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education.Second, much more efforts should be made to put the population planning policy into practice, because more people mean more pollution.Finally, those who destroy the environment intentionalli should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，随着现代社会的迅速扩建，植被大大的减少。

为了保护环境，各国政府做了大量的工作。采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。因此，在当今的环保中政府起着最重要的作用。

我的看法是，为了保护环境，政府应当采取更具体的措施。首先，应当通过教育的方法使人们充分謒到环境保护的重要性。第二，应更加努力把计划生育政策付诸实施，因为人口多就意味着污染严重。最后，要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自己。

保护动物An Appeal for Animal Protection

I am a student from Xinhua Middle 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 。

我是来自重庆新华中学的一名学生。得知你们有一个空缺给学生充当动物发言人，我抑制不住内心的激动，想要抓住这次机会为动物做些什么。

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 fort 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 panies。

我认为，没有什么能够像关心动物一样让我快乐。不管我去到哪里，在做些什么，我会时刻牢记动物是来自天堂的天使，带给我们无尽的舒适和快乐。我从小开始就是一名熊猫爱好者。熊猫是如此可爱，给人们带来乐趣，而且它们是我国的国宝。不幸的是，这种稀有物种此刻正频临灭绝的危险。我想要做的是提高人们保护环境的意识，呼吁更多的人关心我们地球的伴侣。

It is my belief that all human beings can make a difference together。 I would appreciate it if my application could get your approval。

我相信，所有人团结起来就会有很大的不一样。如果我的申请能够得到大家的赞成，我将不胜感激。

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, todays 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 peoples 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 peoples being.

My favourite animal is the giant panda. The giant panda or panda is a bear living in central western and south western China. Most pandas live in Sichuan province. Pandas are adorable because of their distinctive black patches around eyes, ears and across its round body. Pandas are China’s national treasures. They’re among the world’s most adored and protected animals. Pandas are the star attractions in the Beijing Zoo. Experts say that despite their sweet public image, pandas are capable of attacking humans, especially if they feel threatened.

Dear classmates,

As we know, some animals are dying out for various reasons. There is no doubt that animals are our friends. With World Animal Day coming near, what should we do to protect animals?

First of all, we should forbid people’s killing animals at random. Second, we should do all we can to protect animals’ living environment. With their living environment destroyed, the animals will become extinct sooner or later. Third, we should try our best to make everyone realize the importance of protecting animals. In a way, protecting animals means protecting ourselves.

Dear classmates, let’s start now and make every effort to protect animals—our good friends!

Stepping into the new century, environment pollution has become more serious than ever since. There are different kinds of pollution. Such as, water pollution, air pollution and noise pollution and so on. It seems that we live on a planet which is full of pollution. Where all these pollution comes from? To a large extend, the environmental destruction is the heavy price that we pay for the rapid development of economy and the growing population. In order to have more fuel, people cut down trees and dig more corals. But the growing needs for energy are hardly to meet. Countless private cars on the street, the gas stations are short of gasoline, even the government has raise the price so many times in order to control the needs of gasoline, but it’s still not working. Overusing the natural resources has already affected the ecological balance. However, the factories still release the toxic air into the sky and the polluted water into the rivers. People still lack of the conscious of protecting the environment. I think it’s time for all of us to do something.

The government should put forward some more strict laws to prevent the environment from being further polluted. And they should let people know more about the importance of environment protection. And we should find the balance between the economic growth and environmental protection. Plant more trees in the deserts and stop cutting down the forest. Forbid the factories to pour the waste water into the rivers directly. Encourage people to use public transportations to work. Both government and ordinary people should join hands together to make our home clean and fresh again. Only in this way, our earth could be a better place to live in.

进入新世界以来，环境污染比任何时候都要严峻。有各式各样的污染：水污染，空气污染，噪音污染等等。看起来我们活着一个四周都是污染源的星球。那么，这些污染是从何而来的呢?在很大程度上，环境被破坏就是我们为快速的经济增长和人口增加所付出的惨烈代价。为了得到更多的能源，人们砍伐树木，挖更多的煤矿，但是还是难以维持日益增长的需求。不计其数的私家车充斥着公路，加油站的汽油严重短缺，政府多次上调油价也未能阻止私家车对汽油的需求。自然资源的过度利用已经影响到了生态平衡。然而，工厂依旧向外排放有毒气体，把工业废水倒入河里。人们依旧缺乏保护环境的意识。我认为人们应该做些事情了。

政府应该施行一些更为严格的法律来防止环境被进一步的破坏掉。他们应该让人们了解到保护环境的重要性。我们要在保持经济发展和环境保护中找到平衡点。在沙漠中植树造林，停止砍伐森林。禁止工厂往河流里直接排放废水。鼓励人们用交通工具上班。政府和普通民众都应该携手保护环境，让我们的家园变得干净整洁。只有这样，我们的地球才能更适合人类居住。

Like tangible cultural heritages such as the Great Wall and the Forbidden

City, intangible cultural heritages like Peking Opera and

Confucius-commemorating rituals are equally crucial. We should make our utmost

efforts to preserve intangible heritages because, without their physical form of

existence, they are in greater risk of extinction.

According to UNESCO’s Convention for the Safeguarding of Intangible

Cultural Heritage (2003), all forms of social customs and habits, folklore,

performing arts, rituals, oral traditions, festivals, traditional crafts and

various knowledge and practices about nature and universe can be classified as

intangible cultural heritages. As a country consisting of a great diversity of

ethnic groups and with time-honored history and civilization, China abounds in

intangible cultural heritages. Cultural heritages connect modern people with the

historical past, allowing them to acquire a cultural and historical identity.

Without cultural heritages, we would be rendered absolutely rootless and we

would find it hard to cope with challenges at present and in the future.

However, the modernization process poses mounting threats to intangible

heritages. Many people have a blind faith in the latest electronic devices. It

is also pathetic to see elderly people in possession of such legacies pass away

without transmitting them to the younger generation. Faced with those

challenges, we should both preserve and renovate our ancestral heritages so that

we can help contribute to the cultural diversity of the world and return to our

spiritual homeland in this age of impersonal science and technology.

Protecting the Wild Animals

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.

上周，我看了一部令人印象非常深刻的关于熊猫的纪录片。一位教授在20年代80年代早期就开始研究熊猫，他到野外生活，多年寻找野生大熊猫的踪迹。结果，他发现，正是人类，让这些可爱的动物面临灭绝。当时，许多人认为，大熊猫变少是因为新生儿的低出生率。这是不正确。人们为了利益砍伐树木，熊猫失去了家园，也没有食物吃。多亏了这些有价值的数据，政府采取了政策去保护它们。所以现在，大熊猫的数量正在增加。人们意识到保护环境的重要性，这也是最好的方法来保护野生动物，因为它们是大自然不可或缺的一部分。

在我童年的回忆中，只养过一个小小的宠物，大家知道是什么吗?一只可爱的乌龟儿!

乌龟儿是我从市场上购买的，那个卖乌龟的阿姨告诉我，这种乌龟儿永远长不大。听了阿姨的话，我对这只可爱的乌龟儿更加的好奇了。

乌龟儿有一个硬邦邦的壳儿，这可是它的“保护伞”哟!它的壳儿是翠绿色的，上面排满了六边形的团，下面也是由六边形的团组成的，只不过是乳白色的;乌龟儿的头一旦有东西碰到了，酒会快速和两队足一起收回壳儿里，显得它特别小心谨慎。这只乌龟儿很特被，头上有个菱形的小红点，特像个“小剑客”。乌龟儿的眼睛水灵灵的、大大的，下面长着一张“樱桃小嘴”;再说说乌龟儿的四肢。它虽然爬得很慢，但动作却很迅速，四肢很灵活;乌龟儿有一根小瞧的尾巴，细得像根毛线。这根小尾巴平时伸出来时一摆一摆的可爱极了!

第一天把乌龟儿买回来是它在小鱼缸里一动也不动的，我还以为它死了呢!过了一段时间，在我和外婆的精心照料下，乌龟儿终于肯把头伸出来了，但有脚步声，它又把头和四肢都收回了它那硬邦邦的“保护伞”里。又过了一段时间;乌龟儿终于和我像好朋友一样，非常开心。

乌龟儿喜欢住在有水的地方(水不能太深)、喜欢吃颗粒较小的龟食、喜欢在平地上玩耍……

动物是人类的朋友，让我们亲近动物、关爱动物、保护动物，让我们从身边做起、从小事做起，让动物和人类成为真正的好朋友!

When it comes to the environment, most people believe that now is in the shake head to sigh: water pollution, dust storm raids, white garbage everywhere... However, more and more people just sigh, but no action. Only when the sky is no longer clear our heads, remembered that should protect our environment? When we were at the foot of the land into desert, just regret not cherish the nature? I want to say, no, we can all start from to protect our school environment, from the small start bit by bit.

Go to school that day, I and several classmates said and laughed to sit into the corridor, see at a distance a cordial and familiar figure, when we miss zhao. Suddenly, she paused, with his head down as if found any. All of a sudden, she crouched down... Strange, she do? Is to tie his shoes? Or a sprained foot? We havent stepped forward, but she from his pocket a piece of facial tissue, hand a pinch, picked a piece of chewing gum on the ground up, wrapped up, and then threw it into the dustbin. She turned around and saw us strange eyes, smiled and said: "not surprisingly, dont say the whole school, even if lets class, if a person a piece of gum, we will be glued here. If everyone take good care of our environment, we can live in comfort."

Miss zhao said good, do better. I think I did pretty good also. For example, our class classroom environment, there are flower, grass, helped my contribution! Since as health group leader, I work hard, meticulous work. If I was in this respect "xiao-he only expenses furore," then I class "plant corner" career for me, but made great contributions

As we all know， the environment around us is getting worse and worse /more and more seriously today。 Water is polluted， we have no clean water to drink。 Many trees are cutting down， some animals are getting less and less。 Some factories are pouring dirty air into the sky。 The population is increasing faster and faster， resources are getting less and less…etc。 Not only does it affect our lives and health， it also has a great affection in the future。 People’s health has been greatly affected by air， noise and water pollution。 Many people died of diseases。 In order to live a better life， something must be done to stop the pollution。 It’s our duty to protect our environment。 We shouldn’t throw away rubbish everywhere。 Trees are very helpful and important for us。 We should plant more and more trees in order to live better and more healthy in the future。

If everyone makes contribution to protecting the environment， the world will bee much more beautiful。 In a word， if everyone pays more attention to our environment， there will be less pollution and our life will be better。 “There is only one earth”， I hope everyone will protect our environment well。

Environmental protection is every one of us to do, make the responsibility of each of us, once you live in the earth, you have to protect the environment, because we want for our children and grandchildren, give them a good living environment, and not to harm the environment and harm to our children and grandchildren.

Its our duty to protect the environment, and some people said: this is an important task, we are a little, it should give the big man to do, we have to do is not to undermine. Many people agree that in the face of this statement, and the I will against it. In fact, environmental protection is more than a great thing, or do we all the citizens of these things, and they will go to the governance, we control our things, mind your own affairs, because environmental protection from a small one.

Environmental protection is a small matter, dont throw a piece of junk, dont chop down a tree, not a one-time items... Maybe, you have the conditions, is a piece of junk, recycling plant a tree, with an item again... This is to protect the environment, is so simple, need not you do more difficult things, environmental protection is just as simple as that.

环保是我们每个人要做的事情，使我们每个人的责任，你一旦生活在地球，你就要保护环境，因为我们要为我们的子孙后代着想，给他们一个好的身活环境，而不是去破坏环境，危害我们的子孙。

保护环境是我们的责任，而有的人却说：这是一个重任，我们是个小人物，这应该给大人物去办，我们不破坏就行了。面对这种说法，很多人都同意，而我就反对。其实，环保不止是大人物的事情，还是我们这些市民的事情，而他们就去治理大事，我们就治理我们的事情，管好自己的小事，因为环保是从一件小事做起的。

保护环境其实是一件小事，不扔一件垃圾、不砍一棵树、不用一次性用品……也许，你有条件的话，就回收一件垃圾、种一棵树、再次用一件物品……这都是保护环境的行为，就是如此简单，不用你做更难的事情了，环保只是这么简单。

一天，风雨交加，树被风吹的东倒西歪，不料一只小鸟被风吹到了我家的阳台上，我一看小鸟受伤了我急忙把小鸟抱回屋里。 给他用棉花布置了一个温暖的小窝，每天给他吃一些食物，每天上学放学我都要看一.看小鸟的伤好了没有，可是意想不到的事情发生了一只大花猫从窗户外面，跑了进来，我看见了心想：“大花猫要做坏事了，这可怎没办呢？”我着急起来。于是我连忙对着大花猫喊:“大花猫，快出去别伤害小鸟。”大花猫像个聋子一样一步一步的靠近小鸟，我突然看见我们家的玩具小狗，我灵机一动想：“猫不很怕狗吗？”于是我便朝着大花猫大叫:“汪汪汪... ...大花猫喵喵叫了两声然后就跑了小鸟一天一天的好了，我看见小鸟的伤好了，我就把他给放了。

对了，我还保护过青蛙呢，不信？我就给你们一一说一说。 那天是星期天，爸爸和妈妈带着我一起去金顶山上玩，我一进门就被那里的风景迷住了，真是山清水秀，鸟语花香，走到了半山腰我看见了一个瀑布，我对妈妈说我想在这玩一会，妈妈一口同意了。我刚走到那就看见了许多小蝌蚪，我便捉了3只小蝌蚪带回家，小蝌蚪在我的精心喂养下，一天.两天. 一个月... ...小蝌蚪终于变成了小青蛙，我高兴的对妈妈说：“我的小蝌蚪变成小青蛙了，把小青蛙放回田野好吗？”妈妈答应了，星期天妈妈带我回到家乡的田野，我把小青蛙放了，小青蛙呱呱的叫两声然后一蹦一蹦的跳走了。

你对保护小动物的事情也很感兴趣吧！那么你也行动起来吧！

我最喜欢小青蛙，因为，他们穿着绿色的衣服，黄色的花纹，白白的肚子，捉起害虫可了不起啦！下面我就给你们讲讲青蛙在成长过程中的变化和它们是怎样捉害虫的吧！

青蛙小时候穿着黑黑的衣服，头圆圆的，叫蝌蚪，长大了以后就变成了现在这个样子。青蛙捉害虫的时候会把舌头伸的长长的，把害虫卷起来吃到肚子里，真了不起，青蛙一天至少能吃70条害虫，一年能吃到15000条，甚至比这还要多，青蛙还是游泳专家，它游得可快了。

但是，现在有很多人把它们抓来吃它们的肉，还把它们抓到市场去卖，这样的行为很不好，所以，我们应该劝他们停止伤害青蛙的行为。我们又应该怎么样劝呢？下面我就给你们讲讲吧！

我们可以说：“你们这样做很不好，如果你们把青蛙捉完了，那农民们的庄稼怎么办？那我们的粮食不就被害虫吃完了？可是，我们还要吃粮食，因为没有了青蛙，农民伯伯只能用农药来杀虫，那些农药被雨水冲刷流到河水里，不是又污染了水源吗？我们人类饮用这样的水身体还会健康吗？所以青蛙对我们非常重要，我们一定要保护它们。”

我希望有更多的人一起来保护这些有益的小动物。

[保护有益的小动物作文400字范例

动物和人类是一对好朋友，他们互相帮助、互相依靠，和睦相处，谁也离不开谁。但是随着时间的推移，由于人类的自身的原因，造成了动物与人类的关系恶化，而且越来越严重的趋势。

星期天，我上网查资料在电脑上无意间看见一则虐猫的视频，看见一个人为了自己的开心，用小刀在猫身上弄来弄去，猫痛地绝望地叫着，那个人越开心。最终小猫死了。那个人就把小猫的尸体扔在荒野。我十分懊恼，我不明白，猫是多么活泼可爱，为什么会有人想要虐待它们。这可真是太残忍了，它们应该知道，猫也是有生命的，我们要保护它们。

对猫是如此，对狗又如何呢?狗是人类忠实的朋友，可偏偏是这忠诚、可爱的狗却成了一些人的伤害。那一次，我和朋友去遛狗。在我和朋友谈天时，几秒钟的时间狗就不见了。我们跑了过去找，看见身穿黑色衣服的男子，手里拿着一个黑袋子。瞧!袋子有个洞!“看，是狗啊!”朋友激动地对我说。我们跟着黑衣人后面，来到了一个废弃的厂房，我们透过缝隙看到了惊人的一幕。里面的人，手上都拿一把长刀，不知道在切什么东西。直到后来我们才明白，黑衣人从袋子里拿出了小狗，把它放在了刀口下。我们十分着急，可是却爱莫能助，只能眼睁睁地看着小狗被杀害，送上餐桌。

活泼的狗是这样的下场，熊又何尝不是呢?去年暑假，我在家里看电视。新闻里报道说，现在有人很残忍，它们把活泼的熊抓住，关起来，给它们做手术，在熊的肚子上安上管子，然后人类每天定时给活熊取胆汁，熊很痛苦。我还在网上找了活熊取胆汁的图片。图片里那些被关在很大笼子里的大熊像个可怜的小朋友，眼睛里流露出无限的恐慌。我看了之后，心里非常难过。

地球是我们人类的家，也是动物的家，我们不能因为动物不会反抗，不会说话，就欺负它们。我要告诉所有的爸爸不要喝熊胆酒，吃狗肉，也要告诉同学们要保护动物。

When the Arctic Ocean freezes over in the autumn, polar bears set off in search of their favorite meals: fatty ringed seals and bearded seals. By the summer, the sea ice begins to melt and break apart. Deprived of access to the tasty seals, polar bears spend the summer fasting. At least, thats whats supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So whats a hungry bear to do?

Scientists once thought that polar bears might survive by supplementing their pinniped diet by turning to terrestrial foods like snow geese, their eggs and caribou.

"Weve had this debate in the literature about whether terrestrial foods are nutritionally relevant to polar bears during the on-land season when the ice has melted."

University of Alberta biologist Nick Pilfold.

"And weve known for a long time, going back to research in the early 70s, even going to back to early explorer logs, that polar bears will consume terrestrial based foods. But the debate was always whether those foods actually add up, energetically." In other words, do these substitutes provide enough nutrition to make up for the lost seals?

To find out, Pilfold and his colleagues estimated the weight lost each day by polar bears in the wilds of western Hudson Bay during the ice-free season, when they could ostensibly be chowing down on terrestrial foods. Then they compared that to the weight lost by bears that are temporarily held in Manitobas Polar Bear Alert Program.

While captive, the bears do not eat. They drop about one kilogram each day. But the wild bears, who had access to the Arctic snack bar, lost the same amount of weight each day. The results are in the journal Physiological and Biochemical Zoology.

"Which is really saying that the terrestrial foods do not have dense enough energy to offset the mass loss. So this idea that bears can just switch from eating sea ice–based food to land food and thats going to help supplement against longer ice-free seasons, that really doesnt show up in the data."

The problem is that polar bears evolved to rely on the marine diet.

"The food on land is protein and carbohydrate based, and the food the polar bears really focus on is fat. Fat is the name of the game for these bears; theyre highly adapted to absorbing that fat into their system and putting it onto their body as body mass, so they can fast on it later on. And the only thing thats going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when theres sea ice."

Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, cant last as long without sea ice. So as the Arctic warms, younger polar bears will disproportionately die out. Leaving the species survival in doubt.

北冰洋在秋季结冰以后，北极熊就会出发去寻求它们最喜欢的食物：富含脂肪的海豹和胡子海豹。海冰在夏季开始融化断裂。这使北极熊在夏季无法吃到美味的海豹，所以它们进入禁食期。至少，情况应该是这样。但是由于地球变暖，温暖的无冰季节越来越长。那饥饿的北极熊要怎么办?

科学家曾经认为，北极熊可能会转向陆地上的食物来补充它们对鳍足类动物饮食的需求，进而生存下去，这些陆地食物包括雪雁、雪雁蛋和北美驯鹿。

“文献中有过这类辩论，即在寒冷融化时陆地食物是否能满足北极熊的营养需求。”

尼克·皮尔福德是加拿大阿尔伯塔大学的生物学家。

“通过上世纪70年代初的研究，还有早期的探险者日志，我们很早以前就知道，北极熊会以陆地食物为食。但是辩论的焦点在于，这些食物是否能增加北极熊的能量。”换句话说，这些替代食物能否为北极熊提供足够的营养，弥补不能进食海豹带来的损失?

为了解开这个疑惑，皮尔福德及同事对西哈德逊湾荒野地区的北极熊在无冰季期间每天失掉的体重进行了估算，从表面上看，北极熊在这段时间食用了陆地食物。随后，他们将这一数据与通过马尼托巴北极熊预警计划暂时捕得的北极熊所失掉的体重进行了对比。

在被关期间，北极熊不吃东西。它们的体重每天大约下降1公斤。虽然野生北极熊能享用北极“小吃”，但是它们的体重每天也同样会下降1公斤。这一研究结果发表在《生理学和生化动物学》期刊上。

“显然结果表明，陆地食物不能为北极熊提供足以抵消大量损失的能量。所以，北极熊可以从食用海冰下面的食物转向食用陆地食物，并帮助它们对抗日益延长的无冰季这个观点，并没有在这项数据中得到证明。”

问题是，北极熊进化成了依靠海洋食物的动物。

“陆地食物以蛋白质和碳水化合物为基础，而北极熊需要的食物以脂肪为主。脂肪是这些熊真正需要的东西;它们高度适应的情况是，将脂肪吸收进它们的系统中，然后把这些脂肪放在身上以增加体重，这样它们之后就可以依靠这些脂肪来度过禁食期。唯一能提供给北极熊这种脂肪的就是海洋哺乳动物。但是它们只能在有海冰时食用到这些海洋哺乳动物。”

成年北极熊可以8个月不进食。但是小一些的未成年北极熊已经不再被哺育，它们必须要去猎食，可是它们不能在漫长的无冰季期间一直不进食。所以，随着北极地区变暖，较小的北极熊将会大批死亡。这使这些物种的生存成为问题。

Do you know? Time unknowingly. Have you found? Our home into a another look: the bottom of the river became a filth, dirty dust filled the air, everywhere... This is what caused the so huge change? Turned out to be a human that bad habit destroyed the ecological environment, no one has the courage to stand up to stop. Have people unaware of the danger is quietly coming?

News often report news of casualties, such as someone because drink beverages containing chemicals and poisoning, and people were containing sand blown blind eyes... Ah! Absolutely horrible! If everyone around you endlessly environmental pollution, destruction of their homes, so, I really cant imagine that ten years, twenty years, thirty years later... Our home what happens earth-shaking changes, our descendants will blame us, what makes you denied the right to our survival!

Yeah! We dont have the privilege to damage the environment, to destroy their homes. We should not only cherish own life, more want to future generations the survival of the society in harmony with nature, for the sake of nature.

Boys and girls, lets see some action! Protect the environment, care for the home! Everyone to get rid of bad habits, start from around things, such as: dont throw away waste batteries, use water and electricity saving, try to walk or ride a bike... I believe, as long as we carefully action, and will lose everything back to nature, will be our fault compensation back. Let the future home is not painful, but the eternal beautiful young!

你们知道吗?时间不知不觉地流逝着。你们发现了吗?我们的家园变成了另一副模样：清澈见底的小河变成了污泥浊水，肮脏的灰尘充斥着空气，无处不在……这是什么原因造成了这样如此巨大的变化呢?原来是人类那不良的恶习破坏了生态环境，更没有人有勇气挺身而出去阻止。难道人们没有意识到危急时刻正悄悄来临了吗?

新闻常常报道伤亡的消息，比如有人因为喝了含有化学品的饮料而中毒，还有人被含有沙粒的风吹瞎了眼睛……啊!简直惨不忍睹啊!如果身边的每一个人都无休止地污染环境，破坏家园，那么，我真的不敢想象：十年，二十年，三十年后……我们的家园会发生怎样翻天覆地的变化，我们的子孙后代会不会责怪我们——你们凭什么剥夺了我们生存的权利!

是啊!我们没有这个特权去破坏环境，去毁灭家园。我们不仅应该爱惜自己的生命，更要为了子孙后代的生存学会与大自然和谐相处，多多为大自然着想。

同学们，赶快行动起来吧!保护环境，爱护家园!人人改掉恶习，从身边的小事做起，比如：不随便丢弃废电池，节约用水电，尽量步行或骑自行车……我相信，只要我们认真地行动起来，就一定会把大自然失去的一切都找回来，就一定会把我们的过错补偿回来。让未来的家园不是痛苦，而是永恒的美丽年轻!

在我们学习过的一篇课文里，羚羊们为了生存，老羚羊不惜牺牲自己的生命，让年轻羚羊踩在它们的背上跳过悬崖。我的心被这群动物的举动深深地震撼了。而所有这一切都是我们人类造成的，因此在此我提议：

1.不要猎杀动物、鸟类，不乱提动物进行贩卖活动。

2. 不要乱砍伐树木，不破坏鸟的家，不掏小鸟。

我们要号召人类保护动物，不要为了个人的利益去滥杀无辜。否则，最后灭亡的将是我们人类自己。让我们从现在开始“敬畏生命，善待动物”吧！

A few days ago, I saw lots of uncle aunt spitting in the street.

Not, today again see a school wearing a black T-shirt uncle, he casually spit onto the ground. I quickly come forward to stop, I didnt think uncle didnt look at me, continue to go forward.

Sometimes, the grandpa in the home also can make the same mistake. Driving well, suddenly to a screeching halt, opened the window one mouthful phlegm vomit. When I stop him, he said: "it doesnt matter." But Im not discouraged, see uncle, aunt spit anywhere, I will stop them in time. Remind them to pay attention next time. If they had followed my advice, my in the mind is better than eating the honey still sweet. For example, the last time I go to the park to play, my father and mother saw a aunt walked into the grass, vomitted an one mouthful phlegm. I saw hurriedly block, aunt smiled at me and said "Im sorry, but I will pay attention next time." At that time, dont mention how much I have a sense of achievement.

Whenever grandpa didnt listen to my advice, I would reason with him. "Spit to influenza infection, diseases such as tuberculosis, harm is very big, do not only their uncivilized, also hurt others, also caused great damage to our environment." Grandpa heard my these words have never spit sputum. Mistakes can change or good comrade!

For one hundred days after the youth Olympic Games, let us work together, starts from me, do civilization from nanjing, nanjing and beauty.

前几天，我看到了由很多叔叔阿姨在马路上随地吐痰。

这不，今天放学又看到了一位穿着黑T恤的叔叔，他很随意地把痰吐到了地上。我急忙上前阻止，没想到叔叔看都没看我一眼，继续往前走。

有时，家里的爷爷也会犯同样的错误。开车开得好好的，突然来个急刹车，打开车窗吐一口痰。我阻止他时，他却说：“没关系的。”但我并没有气馁，看到有叔叔，阿姨随地乱吐痰，我就会及时阻止他们。提醒他们下次注意。如果他们采纳了我的建议，我的心里会比吃了蜜还甜。例如，上次我和爸爸妈妈去公园玩，看见一位阿姨走进了草丛，吐了一口痰。我看了连忙阻止，阿姨友好地冲我笑了一下，说“不好意思，我下次会注意的。”那时，别提我多有成就感了。

每当爷爷不听我劝告的时候，我就会跟他讲道理。“吐痰容易传染流行性感冒，肺结核等疾病，危害很大，这样做不但自己不文明，还害了其他人，对我们的环境也会造成很大的破坏。”爷爷听了我的这一番话就再也没有随地吐过痰。知错能改还是好同志嘛!

为了一百天以后的青奥会，让我们大家同心协力，从我做起，做文明南京人，创美丽南京城。

I have a puppy, and I love it very much. Its black eyes are like two black gems, and its fur is like a blanket, and its four legs are like four furry little pillars, and its tail is shaking and it seems to be waving to you.
