在动物园看得到大象，我第一次亲眼看到大象时，觉得它的身体像一面大墙，象腿象四根大柱子，象鼻像一根大吸管，把食物通通送到嘴里;虽然庞大的身躯让人害怕，不过它的一举一动让我觉得很可爱!

大象，它的力量很大，在泰国，他们会利用大象来搬运东西，或者当作交通工具，发现大象真的很“勇健”，坐在它的背上行走，会感觉到摇晃颠簸，相当有趣呢!

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!

Contribute to nature reserves and other wilderness areas.Habitat preservation is one of the best ways to help protect animals.You can donate money or volunteer your time helping the nature reserve preserve habitat.

Buy environmentally friendly goods.Choose non-toxic cleaners and lawn care items that wont pollute streams,rivers or oceans.Avoid any products that have been made from threatened or animals.Buy foods and goods that are made from materials that do not harm animals or their habitat.For example,look for organic chocolate,coffee or cotton clothing that is grown without cutting down rainforests or destroying habitat.

Create or restore habitat for animals.You can volunteer to help with projects worldwide designed to reestablish habitat.In your own backyard,plant a butterfly garden,use native plants and trees and let "wild" areas grow to provide habitat and food.

Join a local,national or global conservation organization.Some organizations focus on one particular animal while others focus on broad efforts for all species.You can "adopt" an animal through these organizations,which makes a great gift idea as well.

促进自然保护区和其他荒野地区。栖息地保护的最好方法之一是帮助保护动物。你可以捐款或志愿时间帮助自然保护区保护栖息地。

购买环保商品。选择无毒清洁剂和草坪护理项目,不会污染河流,河流或海洋。避免任何威胁或动物制成的产品。购买食品和产品,是由材料,不伤害动物或它们的栖息地。例如,寻找有机巧克力、咖啡或棉衣服,没有砍伐热带雨林生长或破坏栖息地。

创建或恢复栖息地的动物。你可以志愿帮助全球项目旨在重建的栖息地。在自己的后院,工厂一只蝴蝶花园,使用原生植物和树木,让“野生”地区生长提供栖息地和食物。

加入一个地方、国家或国际保护组织。一些组织专注于一个特定的动物而其他人关注广泛的努力为所有物种。你可以通过这些组织“采用”动物,使一个伟大的礼物的想法。

在我的外婆家有一只可爱的狗,因为它全身毛是黑色的，长得十分健壮，神态憨厚可爱，我们给它取了一个好听的名字叫黑虎。

都说狗是通人性的，黑虎在这方面表现得特别突出。不管你在什么地方喊它的名字，只要它听得到，就一定会来找你。每次我去外婆家，在不远的桥上，我叫一声黑虎，它都会摇头摆尾过来迎接我们，和我们好好亲热一番。

黑虎不但通人性，而且令人钦佩，在我心中的形象显得特别的高大。

记得那是一个周末，天气非常晴朗。我和爸爸、妈妈一块去外婆家过周末。 在路上，我们遇到了一条大黄狗，凶巴巴的朝向我们冲过来，当时把我们一家三口给吓惨了，我躲在爸爸的身后，差点哭出声来。说时迟、那时快！突然从后面冲出一条黑色的狗，和那条黄狗打了起来，把它赶跑了。等我回过神一看那条狗，原来是黑虎！这一次我陪黑虎好好玩了个够，以示感激它的救命之恩！

这天下午，我和表姐去后山上玩耍。从我们一出门，黑虎就一直跟在我们后面，就好像我们的保护神，一步也不离开我们。我们在山上玩了一会儿，看见一条比黑虎高大而强壮的灰狗挡住我们的去路，在它的旁边，正是刚才被黑虎打败的那条黄狗。原来这家伙搬来了援兵啊！那条灰狗显得十分骄傲，懒洋洋的，一点都瞧不起我们的黑虎。但是黑虎一点没有惧怕的神色。灰狗和黄狗发出多次挑衅，黑虎在忍无可忍的情况下，趁敌不备，猛地冲上去，一口咬住灰狗的后腿，痛得灰狗嗷嗷直叫，黄狗这时已经吓得魂飞魄散，逃了老远。在和灰狗的打斗中，黑虎慢慢地占了上风，最终灰狗大败而逃，亲爱的黑虎也受了伤，我们伤心透了。回家后，我和表姐一起找来卫生纸给它擦去鲜血，还给它上了一点云南白药。看到我们着急的样子，黑虎用它的舌头舔了舔我们的手，好像在叫我不要为它伤心。

经过这件事以后，黑虎英雄般的形象就永远留在了我的心中。我们和黑虎的感情加深了许多，每次回外婆家，它都会到大桥上迎接我们；每次我们离开，黑虎都要送我们一程。

Animals are our good friends. People should be friendly to them. But now, many people in China as well as in the world kill animals in order to get money. Its well known that there are many kinds of rare animals in China, such as pandas, golden monkeys and so on. Some people catch or kill them. They use their furs and skins to make clothes and shoes or eat their meat. As a result, a lot of rare animals have disappeared.

What a pity!

At present, our government have made some plans to punish these people. Recently, some nature parks have been built. Lots of money collected for protecting them. For example, some students put on perfom ances or have other kinds of activities to collect money for rare animals.

Its our duty to protect wild animals. As nature is like a big family, man and animals must live together in it peacefully. We must keep the balance of nature. If we do like this, our world will become better and better.

动物是人类的好朋友，人们应该善待它们，但现在，中国和世界上的许多人为赚钱而捕杀动物。众所周知，中国有许多珍稀动物，如熊猫、金丝猴等。一些人捕杀它们是为了用它们的皮毛制衣制鞋，或是为了食用它们的肉。

结果大量的珍稀动物死亡了，真可惜呀!

目前，我国政府已制定出有关严惩不法分子的法律;近来又建起了一些自然公园;人们：也捐款来支持保护动物的活动，如，有些学生通过义演或用其它方式为保护珍稀动物积极筹款。

我们有义务保护野生动物，因为自然就像一个大家庭，人类和动物必须和平共处：我们必须保持生态平稳。

如果人类能这么做，这个世界就会越来越好。

i have a pet, dog. he has brown feather, and he is very small. i like him a lot, because he is so clever、beautiful and cute. he is so cute that i want play with him every day, but i can’t. even if i can’t play with him every day, but i can play with him once a week or twice a week. his legs are neither long nor short. he can run fast, and he likes eating meat and fried rice. he often plays outside. he is our good friend, and that is why i like him a lot.

A thought-provoking dialogue between the mother elephant and her own child appears in the first picture. Having growing his teeth, the young elephant is eager to share the exciting news with his mother. However, after repeating his words several times, there is still no response coming from the mother. Meanwhile, the attractive caption in the second photo reads: no trade, no kill.

The above pictures unveil a hazard posed to wildlife due to the expanding scale of world commercial hunting. At least two fundamental factors could contribute to this phenomenon. The industry of commercial hunting have undergone a booming expansion (along with the growing public awareness of the merits of wildlife, which makes/), making hunting unusually profitable. Worse still, lacking knowledge regarding the significance of ecological balance, some people take the gun to chase animals insatiably (and thus cause a severe threat to all life in the world). Apparently, this trend will surely in turn endanger humankind in the long run.

(On no account should we turn a blind eye to such things.//All these factors above make it crucial to take drastic measures to protect the wildlife.) Accordingly, governments all over the world are supposed to unite to work out effective measures against commercial hunting. Additionally, people should be educated from childhood to cultivate the awareness that we and the rare wild animals share the same precious planet. I do believe a harmonious relationship between the wildlife and human beings is awaiting us if we make every effort to promote wildlife protection both nationally and internationally.

Mark suddenly had a bad bellyache before class began this morning. His classmates immediately sent him to the Peoples Hospital nearby. In the hospital, the doctor gave him a medical check-up.

春天到了，青蛙又开始“呱呱”地唱歌了，我发现又有人在田野里开始捕捉青蛙了，使青蛙成为那些人的“盘餐中”，我感到非常痛心。

Spring has come, the frog began to "Gua Gua" to sing, I found someone in the field began to catch frogs, the frog became those who "tray", I feel very sad.

青蛙是动物世界中最出色的“庄稼的保护神”。它头上那两只圆而突出的眼睛，能让它看清庄稼天敌，但捉害虫全靠它又长又宽的舌头，舌根长口腔的前面，舌尖向那么一伸，快速地伸长长的舌头，一下子把害虫粘住，然后吃掉。青蛙的背上有绿色的深色花纹，腹部是白色，能帮它逃脱天敌血盆大口。身体下面有四条腿，前腿短，后腿长。青蛙是两栖动物，不仅能在地上跳，而且也能在水里游。

The frog is the best protection of God in the animal world "crops". Its head the two round and protruding eyes, can let it see the crops of natural enemies, but to catch insects depend on it long and wide front long tongue, tongue in oral cavity, the tip of the tongue to then extend, rapid elongation of long tongue, all of a sudden the vermin stick, and then eat.

Frogs eat mosquitoes, flies, moths and other insects, locusts, a day can eat only about 120, six months down can eat only 15000, this is how big a contribution wow! Even the frogs, tadpoles can also destroy larvae of many of the pests miles! Really deserves to be called "the crops the protection of God", farmers uncle a good assistant!

从现在开始，我们一起保护“庄稼的保护神”------ 青蛙吧!让我们共同保护[动物]生态平衡!

From now on, we work together to protect the "protection of God" crops - frog! Let us work together to protect the ecological balance [animal]!

在我家里，有一只可爱的小狗，名叫Andy。Andy是一只黑色的贵宾犬。它全身的毛都是大卷的，眼睛水灵灵的，又大又圆，漂亮极了。它的黑鼻子总是湿漉漉的，好像一块即将融化的黑色小奶油。它的耳朵犹如一对小扇子，时不时摇一下。它的嘴巴长长宽宽的，嘴巴时不时舔一下自己的小鼻子，可爱极了!Andy可是有很多种模式的呢!今天，我主要说一下“欢迎模式”。

每一次它看到我回到家，就会启动自己的“欢迎模式”：首先“呜呜”的叫几声，好像在说：“小主人，你终于回来了!”然后它在自己的小“床”上抓几下，它想站起来，可是又不敢，只有叫一声“Andy，来吧!”它才蹑手蹑脚的走过来，它的肚皮紧贴着地面，走路不是走“狗步”而是走“猫步”啊!然后在我身边转几圈，它边走边看着我，每次还会摇头晃脑一下呢!然后它每一次要跳几下，用鼻子碰我的手，如果我换鞋时，它会去用它那湿漉漉舌头舔着我的手，好像想帮我换鞋一样!只要我摸着它的头，它就知道我让它乖乖的坐下来，然后它会一直乖乖的坐下来，一直等到我走到洗手间，才开始动。动起来了，会就一直跟着我，直到我进房间。到这都会一直守在我的房门口，直到我出来!“欢迎模式”到此结束!谢谢!

看，这就是我们家的小狗，一个会开“欢迎模式”的小狗!

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。

Children, you grabbed the small tadpoles right, you must know that tadpole grew up to become small frog, the frog can eat insects, so the frog is our humans good friends. We should protect it, not hurt it. But some hotels are also sold the frog meat? Once, dad and his friends took me to dinner. A waiter said: "you see, this is we store the launch of new specials, stir flogs ball". "Chicken is what ah?" I curiously ask, "chicken is the frog." The waiter said, with a smile. I was very angry, because they hurt our good friends-frog! Another thing, he makes a big inspiration. One day, when I finish school, saw a man at the school gate at little chicks must sell, and I will have mercy on them. Because the little chicks must first came to this world, away from the mother, away from the mother love and mother warm embrace, and this is what they faced starved to death, the risk of freezing to death. At that time I thought: we humans are so happy! When you see here, did you see to protect our human friends-animals!

小朋友，你们抓过小蝌蚪吧，你们一定知道蝌蚪长大要变成小青蛙，青蛙可以吃害虫，所以青蛙是我们人类的好朋友。我们应该保护它，而不是伤害它。 可是有些饭店还卖青蛙肉呢。有一次，爸爸和他的朋友带着我去吃饭。一位服务员过来说：“您看，这是我们店新推出的特色菜，爆炒田鸡球”。“田鸡是什么 呀?”我好奇地问，“田鸡是青蛙。”服务员笑着说道。我当时很气愤，因为他们伤害了我们的好朋友——青蛙!还有一件事，他对我有很大的启发。一天，我放学 的时候，看见一个人在学校门口卖小鸡仔，我好可怜它们。因为小鸡仔刚来到这个世界上，就远离了妈妈，远离了母爱和妈妈温暖的怀抱，这也使它们面临着饿死、 冻死的危险。当时我想到了：我们人类是多么幸福啊!当你看到这里时，你是不是明白了要保护我们人类的朋友——动物呀!

Dog is my favorite animal. The reason why I like it most is because it’s very competent. Dog is the best friend for mankind. It is also the best companion for the old people. The dog can feel the human nature. So many old people will raise dogs if their children are not with them. The old can give their love for their children to the dog to make themselves feel warmly. I believe the seeing eye dog is very famous. They are special dogs. Those dogs will guide their owners whose eyes is blind to go the correct way. See, I say dogs are very competent.

我最喜欢的动物是狗。我最喜欢它的原因是因为它很能干。狗是人类最好的朋友。它也是老人们最好的伴侣。狗是通人性的。如果他们的孩子不在他们身边，很多老年人会养狗。老年人可以把对他们孩子的爱放到狗狗的身上，这也能温暖他们的心。导盲犬是非常有名的。他们是特殊的狗。这些狗会引导眼睛看不见的主人找到正确的路。看，我就说狗狗是非常能干的。

你们一定又自己喜欢我小动物吧!其中我就是一个，我最喜欢得小动物就是我家的小狗，我把它取名为“小白”，因为它全身得毛都是白得，它像一个矫健得小公牛一样。

又一次，我在吃午饭，我刚一下楼，小狗就跑了过来，我不明白，它为什么总跟着我呢?原来-它是饿了，像要吃东西，我把吃剩得饭和猪骨头给了它，我搅得津津有味!吃得时候发出小小声得"汪~汪~"的。像是在说“主人，谢谢你”

记得还有一次，我从学校回来，看见“小白”在门外，我疑惑不解，这么热得天，在门外直射太阳，更奇怪的是：它得嘴里，一直把石头伸出来。我得心吓得半死，以为它生病了，摸了它额头，没又发烧，我以为它傻了，就去问妈妈，“小白”怎么了?妈妈笑呵呵得说：“你错了，“小白”会这样是因为它太热了，无法调理身上得水分，用舌头来保持和调理水分和热量”我明白了，听了妈妈得话，我速速把水放到它面前，果然，它真得喝了起来!

怎么样，这就是我最喜欢的小动物，你的呢?
