我们地球上有许多有益的动物，我们要保护它们。

There are many useful animal we on earth, we should protect them.

青蛙它是两栖动物。它生活在水里，或在靠近水边的地方。它专门吃田里害虫。它是农作物的“忠诚卫士”，是天然的捕虫机。一只青蛙平均一天吃70只害虫，一年能吃掉15000条害虫。

Frog it is amphibious animal. It lives in the water, or in close proximity to the waters. It is designed for field pests. It is the crop "loyal guards", is a natural insect catching machine. The average of a frog to eat 70 pests a day, a year can eat 15000 pests.

蜻蜓也很厉害。一只蜻蜓一个小时能吃20个蝇子或840只蚊子，真令人惊讶!

Dragonfly is also very powerful. A dragonfly one hour to eat 20 or 840 mosquitoes fly, really surprising!

燕子就更厉害了，它一只燕子一个夏天就能吃掉50万条害虫，燕子真是人类的好帮手!

蜜蜂可以给我们人类带来甜甜的蜜，它也对我们有益的，我们要保护它。

Bees can give us to bring sweet honey, it is good for us, we must protect it.

地球上的有益动物，我们都要保护它们。

Useful animal on earth, we should protect them.

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.

With the development ofscience and technology ,different kinds of pollution has been produced andcaused global concern recently.

As we know, people have beenliving on the earth for thousands of years, human activity damaged natural environment, such as excessive abuse of natural resources ,the sewage dischargedfrom factories ,the animal slaughter ,kinds of chemical fertilizers andgreen-house effect. All that is mentioned above has a bad impact on the eco-system .Now, many animals aredying out. We are suffering from unhealthy food and water, we are faced withharmful rays and global warming. It was ourselves who had made a series oftroubles. As you can see, we are the final victim.

Above all, if we human beings cannot recognize theseserious problems and try our best to solve them soon, we would finally lose theenvironment suitable for us to live. So, it is our duty to protect theenvironment ,but what should we do to protect it?

In my opinion, the first and important thing is tounite all forces ,that is to say---gather all hearts together. Next we shouldprotect and plant more trees, which can dispose of the dust in the air. As forfamilies, it is effective to ride bicycles rather than drive cars. Don’t litteranywhere as you like. In addition, sorting and recycling the rubbish also playan essential role in the protection of our earth. We’d better call on everyone aroundus to lead a low-carbon life, as it may make a difference to the environment.

Thus, it’s high time that we did something to improveour surroundings. Everybody should raise the awareness to protect our motherearth. Let’s appeal to more people to join us.

All in all ,there’s no doubt that keeping the balanceof human and nature ,we will benefit a lot.

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 bee 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。

People often say: the construction of a modern city, first of all to ensure that the city should have a good ecological environment.

Every day in the morning to go to school, he always can see the ground clean; At noon after school, I always can clearly see garbage on the ground, and trash can next to the clean, dont these people dont know garbage into the trash can? No, they know, even kindergarten children know garbage to throw into the trash, how come they dont know? They litter is completely in order to save trouble, because they are at the moment of litter didnt thought that could damage the environment, there is no thought that could bring inconvenience to the cleaners. I wonder why, these people have no morality heart? If so, I ask them to stop littering, please them to protect the city, to protect our beautiful home.

Day, the once very blue, but because of air pollution from factories, make the blue of the sky becomes cloudy; Water was very clear, but because the effluent from the factory, once the bottom stream become colorful; Forest, once very lush, but due to the deforestation of people, make once lush forest into a desolate desert...

At our side, there are many "environmental small guards", of course, there are a lot of damage to the environment behavior; Environmental protection of people we need to encourage them to adhere to the environmental protection, destroy the people we need to tell them the benefits of protecting the environment and damage the environment.

I hope that people can do it later "protect the environment, everyone duty", and the ability to truly realize the importance of protecting the environment, and make everyone around him to do this, in this way, our earth will be able to more and more beautiful, more and more prosperous!

人们常说：建设一座现代化的城市，首先要保证这座城市要有良好的生态环境。

每天早上上学时，总是可以看到地面上干干净净的;中午放学的时候，我总是能清楚地看见地上的垃圾，而旁边的垃圾桶里却干干净净的，难道这些人不知道垃圾要丢到垃圾桶里吗?不，他们知道，连幼儿园的小朋友都知道垃圾要丢到垃圾桶里，他们怎么会不知道呢?他们乱丢垃圾完全是为了省事，因为他们在乱丢垃圾的那一刹那根本就没有想过这会破坏环境，根本就没有想过这会给清洁工带来不便。我很纳闷，这些人究竟还有没有公德心?如果有，我请他们不要再乱扔垃圾，请他们一起来保护这座城市，保护我们美丽的家园。

天，曾经很蓝，可是由于工厂排放的废气，使曾经湛蓝的天空变得浑浊不堪;水，曾经很清，可是由于工厂排放的污水，使曾经清澈见底的溪水变得花花绿绿;森林，曾经很茂盛，可是由于人们的过度砍伐，使曾经郁郁葱葱的森林变成了荒无人烟的沙漠……

在我们的身边，有许许多多的“环保小卫士”，当然，也有很多破坏环境的行为;环保的人需要我们去鼓励他们坚持环保，破坏的人需要我们去告诉他们保护环境的好处以及破坏环境的弊端。

我希望，以后人们能够做到“保护环境，人人有责”，并且能够真正地意识到保护环境的重要性，并且使身边的人都做到这一点，这样，我们的地球就能够越来越美好，越来越富强!

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.

我最喜欢的小动物小兔，它有一身雪白的皮毛，看戏来很可爱。她的两只眼睛是红色的，看戏来像一对红色的宝石。亮晶晶的。每天早上这只小白兔吃一根胡萝卜，两片菜叶，它就吃饱了。

My favorite little animal rabbit, it has a snow-white fur, very cute to see the play. Her eyes were red, and the play was like a pair of red stones. Glistening. Every morning the rabbit to eat a carrot, two leaves, it is full.

每天我中午放了学，一回到家，它就蹦蹦跳跳地跳到我的面前，好像在说欢迎你回家。我每天看到它，就算我不开心，我一看到他我就很高兴。把那些不开心的的事情全部忘记了。

Every day I studied at noon. As soon as I got home, it bounced up and down in front of me, as if to say, "welcome home.". I see it every day, and even if Im unhappy, Ill be glad to see him. Forget all the unhappy things.

又一次，我的同学来我家做客，它还是像往常那样蹦蹦跳跳的跑向我，我的同学看见了，她说：“你家的小白兔好可爱哦!回家一会我也让我的爸爸给我买一只小兔子。”

Once again, my classmate came to my house, and it ran to me as usual. My classmate saw it and she said, "your little rabbit is so cute!"! When I got home, I asked my father to buy me a rabbit."

就这样，我越来越喜欢我的小兔子，我一定要好好照顾它!

In this way, I like my little rabbit more and more. I must take good care of it!

我们都知道动物们是我们人类的朋友，它们和我们共同生活在地球上面，跟我们享受一样的资源，但是现在社会上会有很多虐待动物和宰杀动物的行为，这些行为都是很不好的，我们要懂得保护动物，让他们和我们一起生活在美丽的地球上。

最近新闻上总是会有一些虐待动物的新闻，比如说一个男就把自己怀孕的小猫关在了笼子里，活生生的用热水把它烫死了，我觉得这样都是非常没有人性的行为，既然领养了这只动物，就应该好好的对待他，对她负责，而不是用这样的方式来折磨她，我觉得这样是很没有人性且没有良心的，这种行为也应该受到全社会的谴责。然而这个社会上面这个男人的做法并不是隔离甚至在生活上面有很多人会有这样的行为，他们虽然领养了动物，但是却没有好好的对待动物，反而去折磨他们，虐待他们，让他们受到了不好的待遇，又会受到了摧残，还有一些人会对不是自己的宠物的动物虐待和折磨，比如说有的生气的人就会把流浪猫和流浪狗作为出气筒给他们身上发泄，对待他们殴打他们这些猫猫狗狗就会受伤，甚至会被殴打致死，都是非常残忍的。

小动物们都是我们的好朋友，他们和我们共同生活在地球家园上面是我们的陪伴，所以我们和动物之间应该和睦的相处，特别是现在有一些动物已经濒临灭绝了，被设立成了国家的保护动物，但是有一些人执法犯法，野外去捕杀这些保护动物，违背了国家的法律也是没有人性的，这些行为都是不对的，我们每个人都要增强保护动物的意识，让我们和小动物们和谐相处，共同生活，

在美丽的地球家园上。

As is often read in the newspaper reports, wild life especially the rare species is threatened with extinction. Human beings are making attempts to hunt wild animals for a big profit., which, of course, results in a sharp decrease in the number of animals. So it is high time for us to take quick action to protect them. First of all, it’s quite necessary for every citizen to realize the importance of animal protection. Only by knowing its importance can people develop a sense of .

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!

i have two turtles, they are cute. i′ve had them for two years.

在当今追求物质利益的时代，有许许多多珍贵的东西正在快速地消逝，如祠堂、中式婚礼、名人故居等，本文我要谈的是野生动物正在不断消逝。

有许多野生动物数量已经大范围减少，野生动物的锐减与人类有着密切的关系，正是因为人类的随意捕杀和乱砍乱伐，野生动物才日益消逝。人类的这一举动不仅伤害了大自然和野生动物，还伤到了人类自己。直到现在人类才意识到自己犯下了天大的过错，才意识到要极力去弥补这个过错。

现在人们已经把部分濒临灭绝的野生动物保护起来，例如：大天鹅，北极熊，藏羚羊，大熊猫，长江江豚，金丝猴……这些动物曾都被人类伤害过，有的被制成衣服，有的被人类食用，有的被制成药材，有的失去家园……这些残害野生动物的行为全是人类做出来的。

人类这种残害动物的行为是十分可恶的，因为野生动物也曾经给我们做出了许多巨大的贡献，如果我们继续这样伤害下去不就等于是忘恩负义了吗？真是这样的话，不仅是人类自己瞧不起自己，就连野生动物们也会瞧不起我们。所以我们应该停止这种残害野生动物的行为，反之我们还应该去保护他们。

人类是野生动物消逝的重要因素，要是人人都像关心自己一样去爱护那些动物，不要对森林进行大量砍伐，造成无数野生动物无家可归，那么，我相信森林里再不会听到枪声，再没有动物们担惊受怕，再不会在餐桌上看到野生动物的影子，野生动物的消逝就不会出现！

野生动物就像我们人类的启蒙老师，人类现在所拥有的一切都离不开动物。我们应该全力保护动物，与野生动物一同构建一个美丽和谐的家园，对此我想提出以下几条建议：

1、禁止人类猎杀一切野生动物，干扰野生动物的栖息、生活。

2、各省、市野生动物保护区加强对野生动物的保护，对捕杀野生动物的不法分子严厉惩罚。

3、禁止人类近距离接触一切来历不明的野生动物，以免爆发瘟疫，造成大量的人生损失和财产损失，以至扑杀大量野生动物。

4、医务部门要做好防御瘟疫病毒的措施，以免爆发瘟疫时扑杀太多野生动物。

5、时时刻刻宣传“保护动物，人人有责”！

最后，我想对全社会提出：不要再破坏自然界中的花草树木，不要再乱杀一禽一兽，不要再杀害我们的朋友，要保护好自然界中的一个个生灵。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。

we all know that the panda is a kind of lovely animals, but its behavior, some children are not completely know. In order to solve this mystery, recently I have made an observation about it.

The panda is a kind of precious animal, is very attractive. Its shorter in four rubber slow action. On the face of fuzzy embedded with a pair of black eyes. Combined with a black and white hair, more beautiful and lovely.

Pandas like to walk leisurely on the flat ground, play happily. Sometimes looked up people, sometimes low head, as if in search of something, and like to think. When it is happy, somersault on the ground, like a big ball rolling on the ground.

The panda when sleeping, belly up. Sometimes, patting his stomach with his front PAWS, sometimes, it push to the legs, was turned over. I thought it waked up, in fact, it is still in sleep. Waked up just turn it up, with his front PAWS rubbed his change to eyes, curiously at the people, with for she walked away to the other side of the fence to sit down, as if to clear his mind. (pupil composition nets)

When the panda eat, often straight body sitting cross-legged, PAWS grab fresh bamboo leaves to her mouth. It loves to eat fresh bamboo leaves, bamboo stem, and milk and eggs. Pandas eat and drink drink throat. It came to the pool, fell down, the ball pool, lower the head, plump plump to drink up. See the face of it, really makes people laugh.

The panda is one of the worlds rare animals, is a darling of the zoo. Its every move, add fun to tens of thousands of visitors.

一日三餐，都要吃东西，而肉则是必不可少的，我们吃的大多数都是鸡鸭鱼肉，这些没啥大不了。可是一些珍稀动物也被摆上了餐桌，如鳄鱼，江豚，鲸等。

我们都是地球妈妈的孩子，又何必要向兄弟姐妹下此毒手呢？

其实大自然是一个相当复杂的食物链，里面的生物可谓缺一不可。缺了其中的任何一种都会早产极大的后果，就会乱了套。在此就举几个例子吧：

蛇，众所周知蛇是无足的爬行动物的总称目前全球共有3000多种蛇类。身体细长，四肢退化，无可活动的眼睑，无耳孔，无四肢，无前肢带，身体表面覆盖有鳞。部分有毒，但大多数无毒。蛇类中最毒的要数大洋洲的太攀蛇和内陆太攀蛇。它每咬一口释出的毒液已足够杀死100个成年人，最长的蛇要属网斑蟒它。

是人们知道的唯一体长达10米的蟒蛇。网斑蟒通常生活在热带的亚洲地区，依靠身体的重量缠死猎物，眼镜王蛇也应是大家较为熟悉的一种，是最长的毒蛇，喜欢捕食蛇。你们知道吗，在一些地方蛇已经成为了保护动物。你们知道吗蛇的毒液已被用来治疗一些不治之症。而且可以成为史上最强的麻醉剂。

再说鳄鱼。鳄鱼是迄今发现活着的最早和最原始的动物之一，它是在三叠纪至白垩纪的中生代（ 约两亿年以前）由两栖类进化而来，延续至今仍是半水生且性情凶猛的爬行动物，它和恐龙是同时代的动物，恐龙的灭绝不管是环境的影响，还是自身的原因，都已是化石；鳄鱼的存在证明它更加强盛的生命力。

被誉为活化石的他们已经越来越无法适应当前的环境了，仅存的23种中，有17大概种处在濒危状态鳄鱼全身都是宝，他们的皮可以做为鳄皮大衣，肉可以做成汤， 血清提取出来的胎蛋白将成为史上最强大的抗生素，甚至可以抗击艾滋病。这可谓是一项重大成功的发现。

啊！

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。

[保护动物初中作文800字

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。

Recently we have held a class meeting to discuss what is considered to be honorable behavior and what is shameful.It is really a pity to see all this in our school.Some students don’t respect their teachers or parents. Some don’t take their studies seriously and cheat in exams. Some throw wastes everywhere and pollute the environment . It is honorable to obey the law and rules , care much about our class and study hard.It is shameful to break school rules, to be selfish or to make little effort to achieve success.We should respect others and think more of them than of ourselves.We should work hard and make much more progress to repay the society.We should try our best to keep the environment clean。

Recently, it is very popular to live a low-carbon life.Living a low-carbon life is ofgreat importance to every one. First of all, it can protect the environment to a great extent. Second, it can save the limited natural resources and energy, and will leave a better world for our offspring.Third, it is a healthy lifestyle and will help mould a harmonious social atmosphere.

Therefore, how to create a low-carbon life is necessary for us to consider. To begin with, we should save the energy, such as the electricity, water and domestic gas. Second, when we go out we can walk or ride a bike instead of by car. Third, we should not use the plastic bags which are hard to break down. If so, we can live a low-carbon life and gain the happiness of it.

dog is my favorite animal among all the animals.As we all know,dog is a lovely animal.i love it not only because of its cute shape,but also because of its loyalty.it will never betray its master.another reason why i love dog is that dog can make me happy.when i am sad,it will do everything he can to cheer me up and forget the unhappy things.so i will love dog for ever and ever.

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.

动物，本身就和我们人类是同等级的生物，我们只是不过拥有了智慧罢了。但是现在有许多人还在残忍地杀害野生动物。所以我呼吁大家保护动物，也正如有一句话所说的：“枪响之下，没有赢家;没有买卖，就没有杀害。”

保护动物，首先就是要减少、制约那些偷猎者等坏人。我们国家需要不断完善相关法律，加大执法和打击的力度，切实有效的打击罪犯。同时，我们也要减少购买用野生动物制作的工艺品、服饰等非必要的物品。也许你可能在想，一个小小的象牙工艺品，我花了很多钱，也没有关系。但是，只是一个象牙，那么就要杀掉一头成年象，也许在你看来没什么，但是对于象来说，它需要生存多久，躲避那些天敌，才能有这个象牙。所以，保护动物，也要从身边自身做起。

此外，保护了动物，我们就保护了生物多样性，让它继续长存，这也同时间接地保护了我们人类自身。在生物学里，生物多样性是一个很重要的部分，在生物圈里，也就是地球表面发挥着巨大无比地作用。物种越多，这个生物圈里，这个系统也就更加稳定，难以被破坏，或者说拥有了很强的自愈能力。所以，我们地球上的生物越多，我们生态环境也就更加稳定。但是没有了动物等生物，那么我们将会受到自然地惩罚，也终将走向灭亡。

动物，是我们的好朋友，也许你认为老虎狮子等很凶，但是他们也都是为了自保，也只有这样，他们才能更好地生存。此时我，我也相信你已经认识到保护动物的重要性了吧。所以，最后，让我们一起来保护动物吧，一起呼吁，让我们的生态维持稳定，保护动物，保护生态，就是保护我们人类自己。

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.

许多野生动物正面临绝种的危险，因为它们生活的环境发生了极大的变化。例如，随着城市的发展，杀虫剂的使用和严重的污染，他们的生活区域变得越来越狭小。许多野生动物，现在面临粮食危机。同时，人类正在屠杀野生动物只是为了获得它们的皮毛，皮肤，角，牙齿和肉。

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.

为了保护生态资源，人们应该意识到任何物种的缺失，至少意味着知识资源和自然美的缺失。因此，本应采取以下措施：制订污染标准以降低有毒物质;严禁杀害某些稀有物种;应建立国家公园作为野生动物，保护区。

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

我们只有采取一些有力措施，才能保护野生动物。
