With big eyes, there is an emergency ears like flying up to now. You guess what? Let me guess, is the rabbit.

A rabbits eyes like ruby, of course, I also gave a name to my rabbit called ruby. Because the rabbit eyes glistened like ruby.

Remember once, my mother took me to go for a walk, I bring my ruby went to the park. Ruby remembered it home for many years, because of the ruby grew up in the park, but his mom and dad have vanished into thin air, I also know that the rabbit is very poor, but I also didnt find its relatives.

眼睛大大的，有紧急情况耳朵像飞的一样竖起来了。大家猜猜是什么?猜不到吧，就是兔子。

兔子的眼睛像红宝石一样，当然，我也给我的兔子起了一个名字叫红宝石。因为兔子的眼睛像红宝石一样亮晶晶的。

记得有一次，妈妈带我去散步，我带着我的红宝石来到了公园。红宝石想起了它多年的家，由于红宝石是在公园里长大的，但是他的爸爸妈妈却消失得无影无踪，我也知道兔子很可怜，但是我也没有找到它的亲人。兔子很快就竖起耳朵跑了起来，可能是伤心了，我追了很久才追到。

这就是我最喜欢的小动物。聪明、可爱的红宝石。

我家有一只小白兔，它叫多多，很调皮，总是要和我闹着玩。它只要知道我在家里，就会“吱吱”地叫着，让我陪它玩。

它身上的毛全是雪白的，眼睛红红的，耳朵大大的，尾巴短短的，嘴巴成三瓣形，真好看！

有一次，我在做作业。突然感到脚边有什么东西在碰我。我吃惊地往下看，呀，是我的小白兔多多！它怎么逃出了笼子来找我玩了。我看到它在我的脚边转着圈蹦蹦跳跳着。我想自己正在做作业，在没有完成作业的时候是不能够去玩的，于是，我不去理它。小白兔看到我没有理它，就跳到我的脚上。我没有办法只好把它捉住说：“小白兔乖，现在我在做作业。等我做好作业就和你去玩，听话！”然后，我把它关在笼子里。这时，我看到小兔子蹲在笼子里显得不高兴。我也只好回去做作业了。我把作业做完就把多多给放了出来。开始，它在地上不动，好像很不开心。于是，我对它说：“刚才我要做作业，没有办法，现在作业做好了，我就和你玩了。”它好像听懂了我说的话，就和我玩了起来。

玩了一会儿，我看到它跟在我后面摇摇耳朵好像在向我讨吃的。于是，我赶紧走出家门去地里挖了一个萝卜。然后，我拿着萝卜回家。它看见萝卜就跳过来，前爪捧住萝卜就津津有味地吃了起来。看着它吃萝卜的样子，我觉得这小白兔更加可爱了。等它吃好萝卜，我又继续和它玩了起来。

In our country, the number of wild animals is becoming smaller and smaller. Some of them are even dying outThe dangerous methods we human being has taken are as follows:

We have been cutting the trees to build houses, so the home of animals is intruded and they have to find new places to live. In this process, some of them died in the new environment.

The abuse of pesticide has also been endangering the life of wild animals.

In addition, in order to earn money, people have been killing the rare wild animals.

In that we have realized the threat of our behavior to our best friends, we should take actions to change such a condition by taking the following methods:

We should protect the wild animal by protecting the environment that they live in and protect themselves, not to hurt them. At the same time, we should establish more natural reserves for the wild animals.

I believe as long as work together to protect the wild animals, our life will be more and more comfortable.

It is a celebrating day. I got in touch with Michael whom I have been losing contact for one year.

It is really magic. I was searching online aimlessly yesterday when an idea struck me suddenly: since Ben can find out my secret by keying in my name in the search engines, why can’t I do so, either?

I intended to find out something about Ben in revenge in the first place, but soon extend my name list to a wider category. It was then that I recalled Michael suddenly.

We have lost contact since our last correspondence in my senior 3. He mentioned to me in his last letter that he was preparing for going to UK to further his education. I, shamefully, was too busy to reply his mail then. When I was recommended to ZJU and won the final freedom, I thought he had already been in UK so I had no idea where to write him.

I used to think that we would never meet again. However, when I browsed the entries about him, I found out excitedly that he is still in P.R.C.!!

Without a moment hesitation, I ran upstairs to my dorm and found out my old address book. Thank goodness, his home no was still there.

After 3 times calling with no answer replies, I eventually got him on the phone. He was more surprised than I could imagine that when I asked for his hp no he was too nervous to remember it. :P Hehe.

Life is enjoyable in moments such like this. Old friends meet again surprisingly, on a road of their own ways to their dreams. they look at the face of each other, and recognize the old pal. It is such moment that makes me feel grateful to life: whenever I set off for a new destination, I see I have friends in the same direction, with whom I won’t feel alone any more.

目前，濒危的动物正在日益剧增。如何保护濒危动物成了我们的当务之急。人们疯狂的捕杀动物，为了它们的肉、皮毛。我们这样做是不对的，因为动物是我们的朋友，我们应该保护它们，而不是将它们赶尽杀绝。大熊猫就是濒危动物的代表，它生活在森林里，以竹子为食，它们仅仅依靠着自然保护区生存。我们应该停止对动物们的捕杀，更好地保护它们

聪明机智的老鼠

在一个小镇里，有一只老鼠，但是有一只猫，在它的洞外凶恶无比，让老鼠无法进食，猫每天拿着炮竹炸老鼠，老鼠每天都要换石板，不然就要被炸坏洞的。

老鼠已经三天三夜没有吃食物了，一束五彩斑斓的光来到了老鼠身边，那是老鼠圣爷，老鼠惊讶的问：“你不是消失了吗?”圣爷说：“我只是化生成了光，这棵糖能让你变聪明。”吃了糖的老鼠，果然变聪明了。

老鼠晃动自己的小脑袋，一下想出了办法：从通风口顺利的到了冰箱旁边，它跳到桌子上，用圆珠笔撬开冰箱，用了不少力气爬上了冰箱。它看见了纯白如净的牛奶，又肥又香的烧鹅，五彩六色的果冻……它看得口水直流，赶紧吃了起来。哐当一声，一个酒瓶碎了。猫听到异常跑过来，发现老鼠在偷吃东西。这时老鼠也看见了猫。老鼠随手拿起可乐瓶，摇一摇对向猫打开，一个个水泡泡撒进了猫的眼睛……

老鼠不停的开可乐，猫拿了平底锅来档，老鼠把蜡烛放在了玩具枪上，啪!一声闻到了猫肉串的味道。发现尾巴烧起来了，燃燃大火，猫从中国跑到了太平洋了。

老鼠也过上了幸福生活。

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。

Then, the dog suddenly stood up, front legs forward, body and tail of a pretty, "call" to the little black dog ran. The little black dog a strange call and dog fighting. They screamed out "wang wang", move down the road. Puppy seize opportunity, ruthlessly put the little black dog bit the leg, the little black dog bellow out a cry and limped down bone, with tail slipped away. The dog licked his body on the ground and ate with relish.

我家的小狗长得十分可爱，圆圆的脑袋上嵌着一双琥珀色的大眼睛。它有一条粉嘟嘟的舌头，到了夏天总是伸出一大截。它的四肢强壮有力，爪尖是白色的。真逗人喜爱。

小狗吃东西的时候它总是先用鼻子闻一闻，再用舌头慢慢舔。每当我把蛋糕、油饼放在手上，小狗不但很快地把它们吃掉，而且吃得津津有味的。

有一天，一只小黑狗啃着骨头，小狗马上窜上去抢。小黑狗一闪，让小狗扑了个空。接着，小狗猛地站起来，前爪前伸，身子后倾，尾巴一挺，“呼”地向小黑狗扑过去。小黑狗一声怪叫和小狗厮打。它们“汪汪”乱叫，蹿上蹿下。小狗看准时机，狠狠地把小黑狗的腿咬了一口，小黑狗惨叫了一声，一瘸一拐地夹着尾巴放下骨头溜走了。小狗趴在地上舔着身子，又津津有味地吃着“战利品”。

这样可爱、勇猛的小狗叫我怎么会不喜欢它呢?

它要是高兴，能比谁都殷勤，能比谁都温柔。它会冲你汪汪叫几声，或是蹭着你的腿叫你把它抱进怀里，轻轻抚摸它，它偎在你的怀里，静静地躺着，享受着你的爱抚，仿佛是个温顺的孩子。它还很善解人意，在你写作业的时候，它也不吵不闹，只是静静地趴在你身边，摇头晃脑地看着你，或者自己玩，就是不会打扰你;但它若是不开心，情绪不高，你叫它，它也不会理你，更愿意躲在一个角落里，蜷成一团，呼呼大睡;你若这时训它，它的小脾气一上来，就会跟你赌气，然后“离家出走”，出去一天也不见个影儿，让你挂念它。

六一儿童节快到了，小动物们准备在森林里举办一场音乐会，每个小动物都邀请了他们家长来参加音乐会。小动物们为了这次音乐会认认真真地练习。到了音乐会那天，他们都上台了。

台下家长们看了这些演出都捧腹大笑，最后，音乐会圆满结束了。
