Huang, you are my good friend, bring me a lot of fun. I really like you.

我喜欢的小动物是黄雀。黄雀嘴巴尖尖的、小小的，长着一对黑黑的小眼睛。它还有一身漂亮的绒毛，可讨人喜爱了。

一天放学刚回家，就听见黄雀发出了清脆的响亮鸣叫声，我连忙跑过去看。哪知黄雀见我过来，竟不叫了。我有些失落，正要回房间写作业，却发现黄雀吃起食物来了。只见它用嘴啄着用谷子做成的鸟食，时不时又去小杯子里喝一些清水。最令我惊奇的是，黄雀居然会吐壳!是的，它每吃一颗谷子就会有谷子壳落在它的笼子里，可小黄雀还是有点不讲卫生，有些谷子壳掉到笼子外面了。它眯着眼睛，完全一幅惬意样，可真是可爱呀!

还有一次，黄雀把水喝完了，妈妈把它专用的小杯拿出来倒水。我趁机把手伸进笼子，摸了摸黄雀的毛。它的毛很柔软，让人感觉很舒服。黄雀也把身子缩成一团，小眼睛注视着我，活像一个小毛球。我笑了笑，把手松开，关好笼子，它便像从前那么活蹦乱跳了。

听了我的介绍，你也喜欢上可爱的小黄雀了吗?

动物是人们的朋友，我们应该保护它们。

地球上如果没有动物，就没有人类。动物是这个地球生物链的一大部分，如果动物消失了，我们人类也会灭绝。例如：青蛙消失了，就没有动物去捉稻田的害虫，农作物也就无法生长，人类就没有食物；如果没有老虎，兔子就会超额繁殖，我们的粮食就可能会被兔子吃没了；如果没有猫头鹰，老鼠就会侵占我们的地盘。……

地球是一个大家庭，缺谁都不行，如果没有动物，我们人类的处境可想而知，我们大家应该团结起来，保护小动物。

今天，我到了外婆家里玩。到了下午邻居把他们家里养的两只羊放出来，放到田里吃草。我就和田田和她的弟弟一起去拔嫩的草，田田用镰刀割我和她的弟弟用手拔。我们到处拔草，我们拔了小小一篮子。我们回来的时候羊在吃树叶。我们马上跑过去把手里的草给了羊吃，两只羊马上向我们冲来我左手拿草给它们吃。它们在吃草的时候，我摸了摸他们的羊角很硬还有点热。我们把草喂完了以后，一只小点的羊就跑到对面的小树林里去了。另外一只也跑过去了在小树下吃树叶。

我看到了一只大点的用头上的角在树上顶来顶去。我想因为那只羊的角长长了痒，所以顶树。就像小孩子长出牙要痒一样。

如果你是一只动物，却遭到了人类的猎杀，你会怎么想，你愿意吗，你愿意被猎杀吗?你绝对不愿意，有些人说：“我又不是动物。”但你们有没有想过动物们会怎么想吗?现在人类大量捕杀动物，动物会甘心吗?不，不会，永远不会。它们不愿意死在人类手里。它们愿意被你们猎杀吗?不，它们有一千个不愿意，一万个不愿意，一亿个不愿意……

有些人虽然知道怎样去爱护动物，可是他们只会假惺惺地去教育别人，而自己却照样破坏环境，照样兴致勃勃品尝野味。就拿印度洋毛里求斯群岛上生活的渡渡鸟来说，由于它身上的肉鲜美无比，所以遭到当时人类的大量捕食，在十七世纪就已告灭绝。但是如果当时人们有动物保护意识的话，就不会造成渡渡鸟的灭绝。

还有鲸，鲸不是让你们随意捕杀的，鲸是被杀掉一头就死一头的，不像小鱼小虾那样多，如果我们把鲸杀掉了，那我们的子孙后代，他们不是看不到鲸这种动物吗?

现在，有些动物已经灭绝了，鳄鱼虽然凶猛，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。

《金色的脚印》，这篇文章讲了正太郎家捉来了一只小狐狸，两只老狐狸想尽办法就救出小狐狸，正太郎很同情小狐狸，他偷偷地给老狐狸投送食物，于是，他们之间建立了亲密，信任的关系，后来两只老狐狸救了正太郎，最后，小狐狸回归了大自然，两只老狐狸是多么高兴!这篇文章赞美了人与动物之间互相信任，互相帮助，和谐相处的美好关系，也展现了动物之间的浓浓亲情。我们就要向正太郎学习，他帮助动物，动物也救了他，这样不是很好么?为什么人们还是要捕杀动物呢?

在此，我呼吁人们，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。

朋友们，动物是大自然留给人类的无价之宝，它是我们人类的朋友。它们的生衍死灭与我们人类的生活是密切相关的。动物的大量毁灭对人类将产生严重的不良后果，造成生态严重不平衡，从而使人类的生存环境遭到破坏。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!

Traffic and Protecting Environment

交通与环保

2015年11月，全国中东部地区17省市持续雾霾，陷入大范围的重度和严重污染。造成这一现象的主要原因是工厂排出的废气和汽车尾气等。绿色低碳，保护环境，从我们身边小事做起。现请你根据以下三个方面的提示，以"Let’s Do Something to Save Our Environment"为题写一篇80词左右的短文。

内容包括：

1.重要性：只有一个地球。2.主要问题：污染、疾病、灾难。3.措施：停止污染、保护大自然。

Let’s Do Something to save Our Environment

We all live on the earth. The earth is our home. We have only one earth. We must take care of it. It gives us the best environment. If we harm it, it will be angry. And then we will have a terrible end. There are three problems in our earth, they are pollution, disaster and illness.

It’s our duty to protect our environment. So we must plant more trees, protect the flowers and the trees, save energy, reduce the pollution. We should ask our government to control the pollution from the factories.

Protecting the nature is very important. It’s our duty to keep our environment clean and tidy.

If everyone makes a contribution to protecting the environment, the earth will become much more beautiful.

百虎围村，这场惊心动魄的人与野兽的博弈结果如何？带着好奇我翻开了《百虎围村》这本书。愚昧的村民为了改善生活肆意破坏森林、打猎打虎，终于在一次捕捉了虎崽后彻底激怒了老虎们——百虎围村。村民们失去了所有牲畜，而老虎们也遭受了灭顶捕杀，野生华南虎从此杳无踪迹。

带着对百虎围村夺幼崽的敬佩和对华南虎几近灭绝的惋惜，我继续阅读，一个个惊险感人的动物故事跃然纸上：雄林麝为救妻子奋不顾身；兔狲屡战恶人报恩少女；丛林猫护子心切智杀蟒蛇……

大开眼界的同时我被深深地震撼了：动物是充满灵性的，它们有情有义、机智勇敢、爱憎分明，丝毫不比自诩为“高级灵长类动物”的人类逊色。当人类爱护它们时，它们会涌泉相报；然而当人类为了一己私欲不给它们留活路时，它们也不会给人类留活路。我不禁想起了林肯的话——“我对人权和动物权益一样重视，这也应是全体人类该有的共识。”我希望越来越多的人能够敬畏自然、保护动物，我相信如果我们与自然和平共处，大自然也会毫不吝啬地馈赠我们。

One Sunday afternoon, I casually adjust the TV channel. All of a sudden, disastrous scene into my line of sight: a peasant who was holding a piece of iron hammer, turned out to be a butcher is a not how big head of pig slaughter.

I saw all this. Found that pigs fate was so miserable! Is this fate arranged? Or pigs caused by past delicious lazy? I found the "people" are so cruel. Oneself have so long pig, cruel to kill it. Ah, I found that at the moment I was so sad, so sad, so lost, so helpless. In nature there are many more miserable than this things are happening, perhaps this is fate, it is inevitable in the growing of a test.

Not often say that animals are friends of human beings? Not often say that people for the ethical treatment of animals, protect the earth? Maybe this is just for those rare animals! Those animals that almost nearly perish! Pigs in a country of the world, one city, a town, a village, or even a home, a person can see. Pigs are a lot of, is not worth to treat? Pig also is to have life, and human beings, it also know pain, also have feelings, also know how sad. People for the ethical treatment of animals! The animals as their friends, for they give a little love!

Animals are friends of human beings, like humans, are the people of the earth. Let us hands reach out, to protect, to help those who need help human friends!

一个周日的下午，我漫不经心地调着电视频道。突然，惨不忍睹的一幕进入我的视线：一个农民模样的人正拿着一根铁棍敲打什么，原来是一群屠夫正在屠杀一头不怎么大的小猪。

我亲眼目睹了这一切。发现猪的命运竟是这么悲惨!难道这是命运安排好的吗?还是猪前世的好吃懒惰造成的?我发现“人”竟是那么狠心。自己养了这么长时间的猪，竟然狠心杀掉它。哎，我发现此刻自己竟是那么的伤心，那么的悲痛，那么的迷惘，那么的无奈。大自然中还有很多比这更悲惨的事情正在发生，或许这就是命运，这就是在成长中不可避免的一次考试。

不是常说动物是人类的朋友吗?不是常说善待动物，保护地球的吗?可能这只是针对那些稀有的动物罢了!那些几乎将近灭亡的动物罢了!猪在世界的某个国家，某个城市，某个城镇，某个村庄，甚至某家某户都可以见到。猪是很多，多到不值得善待?猪也是有生命的，和人类一样，它也知道痛，也有感情，也懂得伤心。善待动物吧!把动物当成自己朋友，对它们付出一点爱吧!

动物是人类的朋友，同人类一样，都是地球的子民。让我们伸出双手，去保护，去帮助那些需要帮助的人类的朋友吧!

蝴蝶、狐狸……这些小动物尽管十分弱小，可是它们却有着让人不得不佩服的“自我保护大绝招”。

一说到狐狸，人们立刻会想到”狡猾”这一词。没错，狐狸是非常狡猾的动物，一旦发现猎人，它便会悄悄地跟在猎人后面，等猎人布置好了陷阱，狐狸就在陷阱旁边留下一种特殊的气味。当然，我们无法闻到这一气味，只能用特殊的科学仪器才可以检测出来。只要另一只狐狸闻到了这种气味，就绕过机关。所以猎人们总是很奇怪：狐狸怎么这么难捉呢?

蝴蝶尽管没有狐狸那样的机智，可是它一旦遇到敌害，就立即使出它的第一招——“隐身术”，飞入花丛中去，并使翅膀像花一样平展开来，使敌害分不清哪一个是花儿，哪一个是蝴蝶。如果被敌害辨认出来，蝴蝶便使出第二招：飞到敌害的眼旁，撒出一种粉末，使敌害睁不开眼睛，趁机逃之天天。

陆地上的动物都有自我保护妙招，海底生物当然不能落后了!大家来看看它们的神通吧：

刺纯生活在地中海，全身长满了刺，平时贴在身上，一旦遇到危险，便立刻大口喝海水，使身体膨胀成球形，针刺向外竖起，静候敌犯。

海底的鼠鱼一旦遇到了天敌，肠子立即产生一种气体，肚子急剧膨胀，使体积增大好几倍，如同一只充满氢气的气球，迅速浮上海面，逃出敌手。

隐鱼自我保护的方式很妙，时常躲进海参肚子里，从肛门进去，从口中出来，有时海参遇到侵害，经常会丢下下半截，隐鱼就在劫难逃。大家不用为海参担心，因为这也是海参的自我保护方法之一，再过几天，海参就会长出新的下半截。

How to protect our environment has become one of the biggest problems in the world. We do everything can do a real difference to our environment.

We need to pick up litter around us. Youd better join a programme to protect our environment. You mustnt cut down too many trees. We can protect factories from polluting the rivers.

We can do our best to keep the air clear! I hope everyone do these!

ver 70% of the Earth’s surface is water; water is obviously the most precious natural resource that exists on our planet. Without water, life on Earth would be non-existent. Water is the lifeblood of the environment, essential to the survival of all living things-plants, animals, and human. Although we recognize this fact, we disregard it by polluting our rivers, lakes, and streams. Afterward, we are slowly but surely harming our planet to the point where organisms are dying at a very alarming rate, and our drinking water has become greatly affected. In order to fight against water pollution, we must understand the problems and become part of the solution; we also need to do everything possible to maintain its quality for today and the future.The government alone cannot solve the entire problem; it’s up to us when it comes to the problems we face with our water. In your home, correctly dispose dangerous household products. Keep paints, used oil, cleaning solvents, pool chemicals, and other dangerous household chemicals out of drains, sinks, and toilets because many of these products contain harmful substances. In your yard, recycle used motor oil. Avoid pouring waste oil and resist the temptation to dump wastes onto the ground.These are just a few of the many ways in which we, as human have the ability to combat water pollution. If these measures are not taken and water pollution continues, life on Earth will suffer severely.

Every time I go to the zoo, I was always against the stream of people, into the gate, and then turn left, go to see my favorite big bird - a swan

Sunday morning, I have to go to the zoo with mom and dad. Chardonnay at the beginning of the red fire that day, the lake calm a swan in the water, they beat their broad wings, and over the red sun.

我每次去动物园，我总是逆着人流，一进大门，就往左拐，去看望我最喜爱的大鸟-天鹅

星期天的早晨，我又和爸爸、妈妈一起去动物园。那天霞火初红，湖水平静一对天鹅在水面划过，他们拍打着宽大的翅膀，托出了红艳艳的朝阳。

天鹅长着一身雪白的羽毛，显得格外美丽。它们在湖面上娴静得、慢慢地游动着，那平静的湖面像一面明亮的大镜子，倒映出他们那高难度的身影，就像一对舞蹈队员在跳双人舞，使我不禁想谈一首天鹅舞曲，为他们伴奏。游了一儿，也许是累了，便进岸边休息了，树下的房子就是天鹅的家。在这美丽的绿色草坪上，他们静静的望着，远远望去，仿佛是一座雪雕。

我爱天鹅，天鹅是爱美的象征。许多文学家都写过天鹅的故事，好比安徒生爷爷写的童话......看到天鹅，我就仿佛进入了童话世界。

Do you know what my favorite animal? Is the dog of course. My grandma keep a dog, it has a beautiful black hair, a pair of intense big eyes, four legs as fast like a rocket.

One day, I found more doghouse puppy, oh! Originally was born a bitch, a total of four. The dog is cute and naughty, every day running around in the yard, for a while to run the house, ran upstairs after a while, a moment to hide it, run it after a while, as if with a group of friends hide under, from time to time, the old dog to the dog barked two cry, as if to say: "children, dont go to far, pay attention to safety." Play with the dogs have been tired of a day, a meal, stretch and a yawn, into the arms of mother, dogs quickly into the sweet dream sweet, return in mouth every now and then a rumbling sound, as if to say talk in a dream.

The next morning, the birds singing in the branches, wake up the sleeping dog, a yawn, they stretch, rub the sleepy sleepy eyes, began to a day of happy life.

Look! How happy puppy, it is a happiness.

你知道我最喜欢什么动物吗?当然是小狗。我姥姥家养了一只小狗，它有一身乌黑亮丽的毛，一双炯炯有神的大眼睛，四只腿跑得像火箭一样快。

有一天，我发现狗窝里又多了一些小狗，哦!原来是这只母狗生的，一共四只。这些小狗又可爱又调皮，每天在院子里跑来跑去，一会跑屋里，一会跑楼上，一会躲那，一会跑这，好像跟一群小朋友躲迷藏，时不时，老狗还向小狗汪汪得喊两声，好像在说：“孩子们，别跑太远了，注意安全。”玩了一天的小狗们都累了，吃完饭，伸个懒腰，打个哈欠，投入到狗妈妈的怀抱里，小狗们很快就进入了甜甜的梦香，嘴里还时不时的发出咕咕的声音，好像在说梦话。

第二天早上，小鸟在枝头唱歌，叫醒了正在熟睡的小狗，它们打个哈欠，伸个懒腰，揉揉睡意惺忪的眼睛，又开始了一天的快乐生活。

瞧!多么快乐的小狗，真是幸福美好的一家。

动物是人类的好朋友，我们应该爱护它们、保护他们，可有些人却把它们当成了玩具和盘中餐……

先说玩具吧，许多小朋友，甚至一些大人，每次买了宠物，像小猫、小狗、金鱼……养在家里，把他们像玩具一样捉弄、戏弄，我想说：动物也是一条生命!它们也是有尊严的!还有，养小动物如果一时疏忽，有时会把他们弄生病，甚至死亡!

再说盘中餐吧，许多大人喜欢吃野生动物，像青蛙、蛇……这样，使得许多动物都灭绝了!而且对人体也有很大的危害!据说2003年“非典”就是因为这样引起的!我诚恳的告诫大家：“请大家不要再吃野生动物了!”

还有，许多人特别爱吃青蛙，所以有许多人为了赚钱，残忍的杀害了青蛙拉到菜市场去买……请问那些杀害青蛙的人，你们在杀害青蛙的同时，有没有想过，青蛙是人类的好朋友，他们能帮农民伯伯捉害虫、保护庄稼呢?

动物是人类的朋友，请大家保护动物吧!保护动物，人人有责!

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!

人与动物的关系是密切的。我们曾经学过《珍珠鸟》这篇文章，它主要讲述了作者精心饲养珍珠鸟，与它们建立了深厚的友谊。

这篇文章字里行间都流露着作者对珍珠鸟的喜爱之情。人和动物是好朋友，仿佛在千百年前就有了，这感情是无比深厚的。我还记得一个片段的大概内容：作者让珍珠鸟栖息在幽林似的环境中，而且不去打扰它们。《珍珠鸟》的作者不像其他养鸟者那样，只是为了欣赏鸟儿那色彩斑斓的羽毛，倾听鸟儿那美妙动听的歌喉，就让鸟儿成天生活在惊恐中。

某些家长把鸟儿买回来，放在笼子里，然后就对孩子们说：“这是给你们玩的!”孩子们就会听着他们的话对着鸟笼又踢又打，把木棍伸进笼子里挑弄鸟儿，促使让鸟儿惊恐地飞来飞去。大人们不但不加以阻止，还要拍手叫好。鸟儿本来是自由的，如果让那些养鸟人为鸟儿设身处地地想一想，也许他们就知道怎样做了。 还有一个令我记忆犹新的片段：珍珠鸟雏儿在作者伏案写作时，扒在作者的肩上轻轻地进入甜美的梦乡。

我读着，仿佛正亲眼看见这只雏鸟正甜美入睡的情景，眯着眼睛，多么可爱! 相比之下，现在，许多猎人为牟取暴利，去捕杀人类的好朋友，大熊猫、孟加拉虎、非洲象……濒临绝种的原因，就因为它们拥有了人们渴望拥有的美丽的皮毛、洁白坚硬的象牙!在一场场模特表演上，模特儿们披着貂皮大衣，穿着鳄鱼皮鞋，戴着松鼠毛领巾，一转身，迎风摆动的不但是动物的生命，还有血腥!捕杀动物!这是多么丧绝人性的行为!这还是人吗?简直是禽兽! 千百年前，动物是人类的朋友。

我希望从今以后，动物和人类永远和平共处，世世代代，永远是最好的朋友!

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

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。

The global polar bear population could decline by more than 30 percent in as little as 35 years. Thats according to a new study in The Royal Societys Biology Letters.

全球北极熊数量在35年内可能下降超过百分之30。这是根据英国皇家学会生物学快报的一项新研究。

Researchers looked at climate change effect on the Arctic Sea and calculated the likelihood of this projected population drop is 71 percent.

研究人员观察气候变化对北极海的影响，并计算出预计种群下降的可能性为百分之71。

Thats because polar bears stand on Arctic Sea ice when hunting for seals. According to NASA, even the thickest ice in the Arctic Ocean has "either thinned or melted away."

这是因为北极熊捕猎海豹时站在北极海的冰上。美国国家航空航天局表示，甚至北冰洋最厚的冰要么变薄或要么融化了。

And just this week, scientists reported sea ice levels in the area were at a record low for this time of year.

就在本周科学家报告称，该地区的海冰水平创下一年中这个时候的历史新低。

The giant panda （Ailuropoda melanoleuca） （"black-and-white cat-foot"） is a mammal classified in the bear family, Ursidae, native to central-western and southwestern China. It is easily recognized by its large, distinctive black patches around the eyes, ears and on its rotund body. Though technically a carnivore, the panda has a diet which is 98% bamboo. However, they may eat other foods such as honey, eggs, fish, and yams.

The Giant Panda is an endangered animal; an estimated 3,000 pandas live in the wildand over 180 were reported to live in captivity by August 2006 in mainland China（another source by the end of 2006 put the figure for China at 221）， with twenty pandas living outside of China.[citation needed] However, reports show that the numbers of wild panda are on the rise.

The giant panda has long been a favorite of the public, at least partly on account of the fact that the species has an appealing baby-like cuteness that makes it seem to resemble a living teddy bear. The fact that it is usually depicted reclining peacefully eating bamboo, as opposed to hunting, also adds to its image of innocence. Though the giant panda is often assumed docile because of their cuteness, they have been known to attack humans, usually assumed to be out of irritation rather than predatory behavior.

The Giant Panda has a very distinctive black-and-white coat. Adults measure around 1.5 m long and around 75 cm tall at the shoulder. Males can weigh up to 115 kg （253 pounds）。 Females are generally smaller than males, and can occasionally weigh up to 100 kg （220 pounds）。 Giant Pandas live in mountainous regions, such as Sichuan, Gansu, Shaanxi, and Tibet. While the Chinese dragon has been historically a national emblem for China, since the latter half of the 20th century the Giant Panda has also become an informal national emblem for China. Its image appears on a large number of modern Chinese commemorative silver, gold, and platinum coins.

The Giant Panda has an unusual paw, with a "thumb" and five fingers; the "thumb" is actually a modified sesamoid bone, which helps the panda to hold the bamboo while eating. Stephen Jay Gould wrote an essay about this, then used the title The Pandas Thumb for a book of essays concerned with evolution and intelligent design. The Giant Panda has a short tail, approximately 15 cm long. Giant Pandas can usually live to be 20-30 years old while living in captivity.

Until recently, scientists thought giant pandas spent most of their lives alone, with males and females meeting only during the breeding season. Recent studies paint a different picture, in which small groups of pandas share a large territory and sometimes meet outside the breeding season.[citation needed]

Like most subtropical mammals, but unlike most bears, the giant panda does not hibernate.

[edit] Diet

Pandas eating bamboo at the National Zoo in Washington, D.C.Despite its taxonomic classification as a carnivore, the panda has a diet that is primarily herbivorous, which consists almost exclusively of bamboo. This is an evolutionarily recent adaptation. Pandas lack the proper enzymes to digest bamboo efficiently, and thus derive little energy and little protein from it.

While primarily herbivorous, the panda still retains decidedly ursine teeth, and will eat meat, fish, and eggs when available. In captivity, zoos typically maintain the pandas bamboo diet, though some will provide specially formulated biscuits or other dietary supplements.

[动物英语作文：熊猫

老虎是生活在食物链顶端的一种动物，它关系到整个生物链的平衡。因此，保护老虎不单单是保护老虎这么一个物种的问题，而是保护整个食物链完整性的问题。

目前分布于我国的四个老虎亚种（东北虎、华南虎、孟加拉虎和印支虎）中，惟有华南虎是中国独有的。19世纪以前，华南虎曾经广泛分布于以我国东南部为主的国内广大地区。20世纪后，由于自然环境变迁、战乱纷扰及人类活动影响等多方面的原因，华南虎的分布区域不断受到挤压，分布地域面积逐渐缩校直至上个世纪80年代以前，由于捕猎和砍伐森林等活动，使华南虎赖以生存的栖息地受到破坏，华南虎的数量急剧减少。

据以往调查估算，目前中国处于野生状态的华南虎仅有20至30只，养殖在中国动物园里的数量也仅有60只，这仪数量比大熊猫还要稀少。在最近的一次野外考察中，甚至没有发现活的野生华南虎个体，华南虎已接近物种灭绝的边缘。

国家林业局全国野生动植物研究与发展中心的副研究员陆军介绍说，由于动物园中的数量有限，用于交配的华南虎之间的血缘关系越来越亲近，目前有的新产虎崽已经开始出现短尾（尾巴短一结）的现象。毫无疑问，如果任由这一趋势发展下去，在不久的将来，这一世界最濒危动物将不复存在。

透过虎类这一典型的例子，我们更应该保护动物，从自己做起，从他人做起，从身边的小事做起。让我们行动起来保护野生动物，共建和平家园世界将变得更美好。
