第一天，小鸡很小，全身跟鸡蛋似的一样大，我还和妈妈说，这是两只发育不良的小鸡，妈妈说：“刚买回来，就这么大。”然后我又继续全神贯注的盯着小鸡，小鸡也反过来盯这我，好像再说：“你是谁呀?”然后我就哈哈的笑了起来起来。半个月过去啦，有一只小鸡死啦，我伤心地哭啦，我一直在思考为什么会死，原来是吃的东西不对。

一个月过去后，另一只小鸡长大了，都可以蹦出我家的箱子啦。我就换了一个大一点的箱子，可还能迸出来，我就没办法了。

我喜爱的小动物是我家养的斑点狗。它非常可爱，也很贪吃。所以我给它起名为“小贪吃”。

说它可爱，首先要数它那一身好看的黑色斑点，这些大小不规则的斑点就像一件漂亮的衣服穿在它的身上。它还有一双炯炯有神的大眼睛，一个小小的鼻子，脖子长长的，它还有一对耷拉着的大耳朵。它跑起来的时候，胖胖的身子一摇一摆的，可爱极了！说它贪吃，一点也不过分，每当我回到家时，它会活蹦乱跳地向我跑来，并且咬着我的裤子把我拉到狗粮旁边，然后“汪汪”地叫起来。我想它应该是在说：“主人，我饿了，请给我吃点东西吧！”于是，我把狗粮到进狗盆里，它就像风一样地冲了过去，狼吞虎咽地把狗粮吃了个精光。吃完了以后，它充沛的体力似乎瞬间得以恢复，在家里摇着尾巴，跳来跳去，似乎在告诉主人：“谢谢您的关心！”

这就是我喜爱的小动物斑点狗。

My favorite animal is the dolphin. They live in the ocean. And they are cute and beautiful. They not only swim fast, but are also smart. Their color is gray. They can swim and jump in the ocean.

我喜欢许多动物，要说最喜欢的，就是奶奶家的猫了。

这只小花猫长着圆圆的脑袋，大大的眼睛，三角形的耳朵，黑白相间的花纹，它有着胖胖的身子，一条长长的尾巴，还有四只灵活的爪子。

我喜欢逗小花猫玩，小花猫也喜欢和我做游戏。有一次，小花猫正在睡懒觉，我悄悄地走到它的跟前，凑在它的耳边大叫一声，小花猫吓得“蹭”得一下跳出去老远，一溜烟似的逃跑了。我哈哈大笑，小花猫看见是我，它又跑了回来。还有一次，我用一根小木棍挑逗小花猫的胡子，小花猫跳起来又抓又咬，随着我的木棍上蹿下跳，它真像一个无畏的勇士。有时，我还背着奶奶，偷偷地喂小花猫一些火腿啊什么的东西，渐渐地我们就成了最好的好朋友了。

每次从奶奶家回来，小花猫也总是把我送出门外，望着我们远去。小花猫喜欢我，我更喜欢小花猫。

哥哥家养了一只小狗狗，因为小狗长得很壮实，所以哥哥给小狗狗取名叫“肉肉”。

Brother a small domesticated dog, because the dog is very strong, so the elder brother to the little dog named "meat".

肉肉长得非常漂亮，人见人爱。它全身长着黑色的皮毛，那条翘着的小尾巴，总是不停地摇来摇去，那双水晶似的大眼睛，总是充满着好奇，不停地到处张望。

I was very pretty, cute. It was a long black coat, that raised a small tail, always keep the to and fro, pair of crystal like eyes, always full of curiosity, constantly looking around.

有一天，我去哥哥家玩。一到门口，肉肉就站在门口迎接我，我就扮着鬼脸想去摸它，肉肉吓得立即逃走了。晚上，我和哥哥在床上玩游戏，肉肉走过来，把头放在床边，哥哥就帮它按摩，还用梳子梳理着它的毛发。肉肉很通人性，不停地摇摆着小尾巴，好像在说：“谢谢小主人，谢谢小主人。”。

One day, I went to my brothers house. One to the door, I stand at the door to greet me, I made a face to touch it, I immediately scared away. At night, my brother and I play games on the bed, I walked over, put his head on the edge of the bed, my brother will help it massage, also comb his hair.

It seemed to understand my words, kicking ran in the past, with his mouth put the ball has been sent to my side, and in this way, we are happy to play up.

My dog is so cute!

星期六，我去爷爷奶奶家玩，一进门爷爷就跟我说：“家里来了一只小狗。”我赶紧兴奋地往狗窝跑去。

这个小家伙正在睡大觉，我控制不住自己激动的心情，忍不住用手摸了它一下，可谁知，小狗的警惕性那么高，我的手刚碰到它的毛，它就一下子被我给惊醒了。它把眼睛睁得大大的，仔细地看着我，仿佛在说：“你是谁呀?我怎么没看见过你呢?”我一看，哟!圆溜溜的大眼睛，小小的鼻子，樱桃形的小嘴，不胖不瘦的脸蛋，还有一对神气的大耳朵和一条摇个不停的尾巴。夏天的时候它会把舌头舔出来散散热，真是一只帅气的小家伙呀!

吃完饭后，我也想去看看这小家伙吃东西的样子，便拿了一块肉放在地上，我心想：这样美味它一定很喜欢吧。但出乎意料的是，它只是去嗅了嗅，又走到了一边。我想，是不是它怕被人看到才不肯吃呢。于是，我就躲在了门背后，偷偷地观察它的动静。果然，小家伙慢慢地走了过去，四面看了一下便津津有味地吃了起来。看它吃完了一块肉，我便从门后走出来和它一起玩了起来。我把一个球扔到了远处，对它说：“帮我去把球捡回来!”它仿佛听懂了我的话，飞快地跑过去用脚踢，用嘴顶把那个球一直送到了我的身边，就这样，我们高兴地玩了起来。

我的小狗实在是太可爱了!

I have a cat named Mimi. Its hair is as white as snow. I often play games with it. It amuses me a lot and I treat it as a little friend. Every morning, I would say goodbye to it before I go to school and Mimi would wave its front-legs to me. It brings me a lot of pleasure. But it takes time and costs money to keep the cat. My parents and I spend much time taking care of it, feeding it and cleaning it. We have to clean the house from time to time, or the cat will make them dirty and smelly.

我有一只猫，名叫咪咪。它的毛像雪一样白，我经常和它一起玩。它使我很开心，我也把它当小朋友一样对待。每天早上，我去上学之前都会跟它说再见，它也人向我晃晃前爪。它给我带来了很多快乐。但是，养猫是要花费时间和金钱的。我父母和我花费很多时间照看它，喂它饭，给它洗澡。我们得经常打扫房间，否则，猫就会把屋子弄得又脏又难闻。

As we all know , animals are mans friends.Nowadays with the development of industry ,a lot of animals are in danger of extinction. We should protect animals so that we can live in a better environment .To protect them ,our government should forbid people to kill them , and for most of us ,we can plant more trees and call for protecting anmimals habitats.Only if we protect animals well can we have a bright future!

我喜欢的小动物是一只小狗，它全身长满白色的毛，像一团棉花糖;眼睛是圆溜溜的，像两颗大宝石镶嵌在一对弯弯的眉毛下;耳朵是半圆形，鼻子是黑色，尾巴短短的，很可爱。

我给它爱吃的骨头，它会一块一块，一小段一小段地啃。它啃完骨头后，就会汪汪地叫几声，好像在说：“小主人，谢谢你。”每当我去上学，她总是会送我一段路程，直到我假装生气打它两三下，它才乖乖地跑回家去。它不但会送我去上学，还喜欢和我一起赛跑，跑得十分快，有时，把我落了一段路程。平时，它看起来很胆小，但看见陌生人时，却又不失威猛地睁着双眼紧盯着陌生人的一举一动，关键时还会大声叫。

它真是一只机灵又尽忠职守的小狗啊!

我放学回家时，可算是小狗最开心的时候。只要小狗在家，我在放学回家的路上离家门口还有一段路总可看见小狗在门前等着我。它看见了我，就会摇着尾巴往我这里飞奔而来，然后在我人前人后蹦来蹦去。这么机灵的小狗能不讨人喜欢吗?

我很希望把这只小狗养得白白胖胖，因为它实在太可爱了。

在地球上，除了人类，还有什么呢?没错，还有动物。可几年下来，动物的数量逐渐下降。人类有没有把动物当朋友看呢?

On earth, except human beings, what else? Yes, there are animal. But after several years, animal numbers decreased gradually. Human beings have no regard animal as a friend?

动物和人类应该是好朋友，可为什么动物会和人类为敌呢?是因为人类没有把动物发在眼里。比如奶牛。人类用奶牛生产奶牛，可等奶牛没有奶的时候，人类就会把奶牛残忍地杀死。奶牛没奶时，不会将它放生吗?奶牛也是一条活生生的生命啊!近几年的“鼠疫、艾滋病、疯牛病、禽流感”，这些都是动物们奋起反击的预兆呀!难道人类还要打第三次世界大战吗?我们的祖先就是高级动物呀!如果人类再不制止这种滥杀动物的行为，是对我们的地区母亲沉重的打击呀!

Animal and human should be good friends, but why animal and human enemies? Is because people dont send in the eyes of the animal. Such as the cow. With cow dairy production such as human, cow milk can not time, humans will put the cow to brutally kill. Cows milk, will not be released? The cow is also a vivid life ah! In recent years the "plague, AIDS, mad cow disease, avian flu", these are a harbinger of animal who respond! The meeting has also had the third world war? Our ancestors is an animal! If human beings dont stop this killing the animal behavior, is the mother of our area heavy blow ah!

我们现在不要再破坏动物的家园，这样动物们就可以安心繁殖后代。朋友们，还动物们一片蔚蓝的天空，让小鸟自由地飞翔;给动物一片绿草地，让牛羊欢快地奔跑;还动物一片汪洋，让动物无忧无虑地畅游海洋之中。也许，这样可以安抚动物们受伤的心灵。动物原本不坏，只是人类破坏它们的家园，这些只是它们对人类的“报复”而已。

Home we dont damage animal now, so they can feel at ease to animal reproduction. Animal friends, also have a piece of blue sky, let the bird fly freely; to the animal a piece of green grass, let the cattle and sheep running merrily; also a world of waters animal, allow the animal to be light of heart from care to swim in the ocean.

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。

我家养了一只可爱的小猫，名字叫妙妙。它是一只搭乘飞机来到杭州的苏格兰立耳猫。

妙妙的脸圆圆扁扁的，配上它塌塌的小鼻尖，活像个大烧饼。它有一双碧绿的透亮眼睛，长长的胡子像灵敏的雷达，一对尖三角竖耳警惕地向四周打探。它全身覆盖着毛茸茸的毛发，肚皮和颌下的毛是雪白的，越往背上毛色越黄，金灿灿的油光水滑，唯独尾巴尖是黑色的。尖利的小爪子。肉乎乎的黑色脚垫，走在地上不发出一点声响。

妙妙白天几乎都在睡觉，不过只要有一点风吹草动，它就会把脑袋抬起，眼睛眯成一条缝，向四周张望。如果确定没有风险，又慢慢地趴下去继续呼呼大睡。到了晚上，它就活泼了。我经常看见它在下水道旁聚精会神地守着，一旦有小虫子出来，它首先目不转睛地盯着，然后匍匐着身子，四只尖利的爪子紧紧巴住地面，背弯的像张弓，两簇钢针似的胡子根根竖起，抓住时机，闪电般地扑过去，一下子就逮住了虫子。

我家的妙妙有时乖巧得像个天使，有时调皮得如同小撒旦。有一次，我们回到家打开大门，只见一片狼藉，家里好像台风过境一般。我的琴凳上留下了妙妙深深的爪印，那三道利剑似的杰作，看得妈妈青筋直跳；榻榻米上粘了一席的猫毛，不用猜也知道妙妙又偷溜上来晒太阳了；厨房里传来爸爸的惊呼：“天哪，我的鱼！”只见碗罩下的鲈鱼，最肥美的肚皮不翼而飞……我们四处寻找始作俑者：“妙妙，你给我出来！我们保证不揍你！”最后，我在高高的书架上找到蜷成一团的妙妙，只见它轻轻一跃，转眼就卧在我的脚边。它用毛茸茸的身体蹭着我的腿，还翻出柔软的腹部，喉咙里发出咕噜噜的卖萌声音，仿佛在和我忏悔："；哥哥，我错了。"；

我家的妙妙既憨态可掬又调皮捣蛋，真是我的开心果。
