表哥家有一只活泼可爱又机灵的小狗。它有一身棕色发亮的毛，四条腿是棕色有点发黑，两只小耳朵拉下来，还有那条毛茸茸的小尾巴，真讨人喜爱。呀!它还没有名字叫呢，我给它取一个吧，就叫“欢欢”，意思就是让它永远带给我们欢乐!

在去年夏天时我见到了它，那是我第一次见它，有一点害怕，但相处一阵后不但觉得它不怕，反而感觉它很亲切、活泼、可爱。那时正好是夏天，小狗张着嘴哈气，还向我眨眨眼睛，好像在说：“热死我了，热死了，你不热吗?”瞧它那可爱的样子，既滑稽又可笑，真是太讨人喜欢了!

还有一次，去表哥家吃饭，一进门，欢欢就朝我和表姐奔来，快活地围着我们的脚脖子转着，嗅着，亲亲热热的，撩拨得我心头暖融融的。和哥哥、姐姐、妹妹还有小狗，不，是欢欢玩了一会儿便去吃饭了。一会儿吃完饭，我拿着骨头和馍馍来喂欢欢，它围着我撒欢儿，粉红色的舌头吐出来，朝着我，好像在做鬼脸，又好像在嘲笑我，我把骨头和馍馍倒在欢欢的餐盒里，它便迫不急待的冲了上去大口大口的吃了起来，边吃边回头看我，好像很感谢我，看着它憨憨的样子，我不禁笑了起来。

玩倦了，休息休息吧!欢欢钻进了它可爱的小屋里，伸展着它灵巧的四肢，眯着眼睛看着我，好像在故意向我展示它舒服的姿态。我不想打扰它便悄悄躲在旁边看着它，不一会儿欢欢睡着了，它睡得格外香甜，还不时的咂咂嘴，大概在做一个甜甜的梦吧!

我家有一只小狗，名字叫浪浪，我非常喜欢它。

浪浪其实是一只流浪狗，自从遇见我后，就再也离不开了。我走到哪里，浪浪就走到哪里。

就这样，它住进了我家，成了我家的一员。爸爸说：“这只狗到处流浪，就叫它浪浪吧。”

每天放学一回家，一进门，就看见一只浑身白绒绒的小狗，四脚朝天，懒洋洋的躺在地上，

好像在享受日光浴，它就是浪浪。浪浪看见我，连忙爬起来，像箭一样冲过来，围着我转来转去，

一双炯炯有神的大眼睛盯着我左瞧瞧右看看，可爱的鼻子闻闻我的左脚又嗅嗅我的右脚，还“旺旺”直叫唤。我蹲下来，逗着它玩。

浪浪也喜欢交朋友，但只要开饭了，它就会带着几个好朋友一起回家，共享美餐。

现在浪浪已经被送人了。不知它长大了没有？过得好不好？我多么想念它呀！

妈妈再一次带我去楼下玩。突然有一只小狗盯了我一下，我很害怕。我往后退了几步，那只狗的主人说：

“小朋友，你别跑，那只狗不会对你怎么样的。”

可我还是有点害怕。但是一想，不跑就不跑，我是人，它是狗，难道我还怕它不成，便停了下来。谁知，那狗盯了我一下，就调头跑了!我才觉得狗是一个很好玩的小东西。

后来，我竟然叫爸爸帮我买了一只小狗。真的不敢相信，我明明很怕狗的，为什么还叫爸爸买狗呢?

不管怎样，爸爸还是给我买来了一只狗，那只小狗好可爱，亲了我一下。

我看了一下这姿态，想道：好一个高傲的动物啊!

狗的高傲，更表现在它的叫声、吃相和表情中。

狗的叫声，音调严肃郑重呵斥。狗还可以看家门户。现在我知道：凡有生客进我家，狗就会大声地叫，那是在保护我这个家庭啊。

何况，他一看见我就摇尾巴，真可爱!

狗才是人类最忠实的动物啊，从此，我再也不怕狗了。

家有一只斑点狗，它的名字叫乐乐。我还编了一首绕口令：乐乐狗，狗乐乐，乐乐是一只斑点狗，一只斑点狗是乐乐。乐乐的毛很光滑，全身布满斑点，尾巴总是摇个不停，腿又长又细，真可谓是“狗美女”啊！

在日常生活中，乐乐是很文静的，见生人也不咬。可乐乐一撒开，上蹿下跳，活泼极了。一见到别的狗总是要大战一场，然后落荒而逃。真不知道它怎么想的，明知打不过还要硬碰硬。乐乐是很可爱的，我经常摸它，心想：“小乐子你怎么这么可爱呢？”乐乐撒开的时候，总是往我怀里钻，真像一个小孩。

乐乐遭遇了一次灭顶之灾，那是去年的事情了。早上，乐乐安逸的躺在他的小窝里，我也安心的走了，可谁曾想乐乐能受了那么重的伤。这件事是一个小伙伴的妈妈告诉我的，知道这件事后，我急忙赶到家中，可乐乐已经不见了。我伤心极了，我大哭起来！我默默的祈祷着，希望乐乐能够早点回来，皇天不负有心人，乐乐终于回来了，可是乐乐已经遍体鳞伤。伤害乐乐的是两只大黑狗，我不禁为乐乐松了一口气。三个月后，乐乐痊愈了，又恢复了往日的活泼。现在，往日的伤痛已不复存在，但在乐乐内心的阴影是永远不能消除的，那是一次噩梦啊！谁能知道它所承受的压力有多大，乐乐，好样的！

我与乐乐的感情愈加深厚了，岁月的冲刷使乐乐的阴影减去不少。我相信美好的未来正等待着每一个生命去迎接，生命没有卑微之分，去爱每一个动物吧，世界会变得很美好的！

我家的乐乐狗真可爱呀！

The zoo provides the animals the comfortable and safe living conditions that can not be found in other places.

If the animals get hurt or ill, certain people will take care of them to prevent futher danger caused by the diseases.

Good opportunities for the people in the city especially those children who dont have the chance to set foot in the wild world.

Watching the animals in the zoo may give the parents a good chance to teach their children to love the animals and the world.

The parents can get the children know more about the animals in the zoo by watching listening even smelling instead of just looking at the dull pictures in the books.

My Pet

I have a pet. I named him Nicholas. Nicholas is a pure Husky dog. He was about 8 weeks when he first came to my home. We will have his birthday next week and he is turning 2 years old. Good time goes fast. Hes totally mature now but somehow I just refuse to admit it. In my eyes, no matter how big the size he is, hes just my adorable puppy. Owning a dog is a huge responsibility. I spent a lot of time house-trainning him. Youd have to be patient, compassionate, and consistent. Fortunately, Nicholas is a fast learner. Now he knows exactly where to go potty, what time to eat, and how to play. He used to be too energetic and he liked biting. But now, as hes growing up, hes gentle and obedient. On week days, I take him to parks. I toss out his toy and he goes and get it. He loves this game. Nicholas brings me lots of fun and Im proud of being his owner.

周诗语

我拿着礼物蹦蹦跳跳的跟张若依去璐宝家了，结果一到她家门口，就听到一只狗在狂吠。

“汪！汪！汪！”似乎在说：“主人！这里有两个陌生人！快来！”要知道，我最怕狗了。尤其是那种声音很大的狗，但换另一个方面来想，那似乎又是尽职呢！

进门以后，我有机会看清它的真面目：“毛雪白雪白的，甚至比雪花更白呢！一双乌黑的小眼睛正聚精会神地望着我们，让人看了就想上前摸一摸。”

看电影的时候，它一直在笼子里呜咽呜咽地哭，我以为它饿了，就拿了几块狗饼干给它吃，吃完后，它就一直看着我，那双眼睛里有期待，有急切，有……有一切我说不出来的东西，至少我知道了，它想要的不是食物，而是自由！通过璐宝妈妈的允许，它被放出来了。此时此刻，它是那么的高兴，那么的兴奋。当它所有快乐凝结在一起，成为了异常的能力：快！它围着每个人转圈，表达了充分感谢之情。

我喜欢它！

The puppy home grow very cute， round head set with a pair of amber big eyes。 It has a powder doodle tongue， summer is always stretch out a large margin。 Its limbs strong and ZhaoJian is white。 Really cute。 One day， a small black dog chew bones， puppy immediately flee to rebound。 A little black dog a glimmer， let puppies flapping empty air。 Then， the puppy fiercely stand up， its body extension forward， sloping， tail， a pretty， "shout" to swoop in little black dog。 Black dog a strange call and puppy takes。 They are "bow—wow" monkey ShangCuan next leap up。 The puppy seize opportunity， ruthlessly put a little black dog legs bite， little black dog bellow out a cry and limped its tail between its legs down bone passed。 The puppy licked his body lie on the ground， and with relish eating "trophies"。

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。 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”。

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 become 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。

My favorite animals are rabbits. Rabbit is very cute, chubby, hairy. Its head is small, two long ears, like two big fan inserted in the head, as long as there is a little static and dynamic, it will be kept on the ears before and after the swing. It is particularly beautiful eyes. It also has an endearing three mouth, the above two, the following one. Jigen on both sides of the mouth are thin beard, it always put the two long vertical whiskers were straight, and appears to be very spirited. Small rabbits love to eat green vegetables, red radish, but it is still the most favorite carrot. Rabbit likes to play on the lawn, it danced on the lawn, never mind played with more fun.

Rabbits are very docile personality. It tenaciously to protect their own: it could run very fast to see the wolves, tigers, lions and so on, it flew drilling holes; if hawk Diao it, it will be overturned, with four legs to go into eagle; I very fond of rabbits

我最喜欢的动物是兔子。兔子很可爱,胖胖的,毛茸茸的。它的头很小,两个长耳朵,像两个大风扇插在头上,只要有一点静态和动态,它将保存在耳朵前后摇摆。这是特别美丽的眼睛。它也有一个可爱的三个口,上面两个,下面一个。Jigen两边的口是薄的胡须,它总是把两个长垂直胡须直,和似乎很激烈。小兔子爱吃青菜,红色的萝卜,但它仍然是最喜欢的胡萝卜。兔子喜欢在草坪上玩,它在草坪上跳舞,更不用说玩更有趣。

兔子很温顺的性格。它坚持地保护自己的:它可以跑得很快看到狼,老虎,狮子等等,它飞钻孔;如果鹰叼它,它将被推翻,四条腿进入鹰,我非常喜欢兔子

我外婆家有两头大狼狗，一只公的一只母的。有一天，母狗生了六只小狗，周末的时候，我去外婆家玩，看见了六只小狗，它们很可爱，我和两个哥哥逗着它们玩，它们一会儿跑到这里，一会儿又跑到那里，蹦蹦跳跳，真可爱。

以后每个周末，我都跑到奶奶家里看小狗，看着小狗渐渐地长大了。

过了几个月以后小狗已经长得和它们的爸爸妈妈差不多大了。

它们个个都是看门的好帮手，我舅舅是办工厂的，那六只狗都在工厂里看门和材料。它们很聪明很活泼。狗是我们人类最忠实的朋友。

我家有条小狗，一身黑白相间的毛，一双圆溜溜的眼睛像两颗黑宝石，尖尖的耳朵，加上眼睛下面那只小小的鼻子，凑成了可爱的小狗。

小狗步态真可爱，右边腿先跑上去，左边腿又跟上来，右边的腿又跟上来，他有时慢慢悠悠，有时又飞快地跑着。

小狗的吃相常使我发笑。我们家的狗是吃火腿肠和牛奶的。我们一般都是给它两个碗。每次它吃火腿肠时我都要切成一片片地给它吃，切大了怕它嘴巴包不下，切小了怕吃不出味道。所以要不大不小的切好，就为这点小事还浪费了我不少时间呢!它吃的时候先用牙齿咬住火腿肠在用舌头舔牛奶，我想它应该喝到牛奶了吧!

我家的小狗还是跑步高手呢!有一次，我和它比赛跑步，小狗对着我“汪汪汪”地叫着，好像在说“小主人你先跑”而且还摆出一副高傲的样子，我也不示弱，先飞快地跑了出去，我想：哼，叫我先跑，你就等着跑最后吧!我心里暗暗的高兴，可是我一看旁边，“啊”!~小狗竟然在我旁边，我惊讶的很。后来小狗得了第一名。

我的生活自从有了它，就快乐了很多。

[狗狗的最后一天英语作文

有一天，我在路上遇到一只小狗。它非常的可爱，它全身都是土黄色只有尾巴是黑色的。我问它：“你的主人是谁?”小狗好像听得懂我的话一样，摇摇头仿佛在说：“我没有主人，我是一只流浪狗。”

我真想把它带回家，心里想：“到底要不要把它带回家？如果把它带回家的话，一定会被妈妈给拒绝的，可是它很可爱而且还很乖，带回家应该不会被妈妈拒绝的吧。”最后，我还是忍不住把它带回家了。“哈哈，真是老天有眼啊。”我很兴奋地跑着。因为在那天回家之后，妈妈也觉得它很可爱，就问我要不要养它，“当然要啰！”我回答说。

所以，我成功收养了它。每天吃完后我都带着它去公园里散步。突然，有一天我发现它瘦了很多就把它抱出来看一看，可是，它却用一副凶恨的表情看着我，这时我才发现，这是一只母狗它生了三只小狗狗，怪不得它最近都不和我去散步呢。小狗的到来本来就让我十分兴奋，现在它又给我们生了三只小狗狗更是让我高兴的说不出话来。

时间过的飞快，转眼间那三只小狗长大了，它们个个都已经是身强力壮的成年狗狗了，我用它们来看家啊、训练等等本领。在它们三个小狗中有一只小狗它跑得非常快，如果你想赶上它的话可不容易。如果你和它比跑步的话，它会先跑一段路，当你快到它的地方的时候，它就会再往前跑一段再在那里等你。从此我们一起过着幸福快乐的日子。

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。

I have a pet dog named Lucky.It has white and soft furs with two small ears and a long tail.It is given by my aunt as my birthday.It is so friendly and lovely that we all love it very much.It likes playing balls outside so I often take it our for a walk.It also likes to be clean so I wash it and make it clean twice every week.I often feed it with dog food and saussages.It likes one of my best friend.I often play with it after school.

在我们共同的家园——地球上，生活着许许多多的动物，你喜欢哪种动物呢?反正我最喜欢的动物是我们最忠诚的朋友——狗

我们家就养了一条狗，他有一个好听的名字叫“金豆”。我们全家人都很喜欢它，平时的时候它总会给我们带来很多乐趣，下面我就来介绍介绍它的外貌。

他有一双特别的眼睛，你们猜一猜是什么颜色的?告诉你们吧，是红色的漂亮得无法形容。嗯，像一个红宝石。你们别看她是一条母狗，她可也是有胡子的。它毛发的颜色呈棕黄色。他的品种是泰迪，他拥有高贵的气势，你们千万可别以为她好惹，只要一有狗靠近我，她就会保护我，所以呢全小区的狗都怕她。你们可别小瞧她，她可以是4窝宝宝的妈妈了。

它很可爱，有一次我考试不及格，很伤心地回到家，金豆突然跳到我身上，舔了舔我的脸和嘴，还汪汪叫了几声，像是在说：“主人，别难过，别灰心，下次再努力!”看到金豆那可爱的神情，我一下子忘记了伤心。

我家的小金豆啊!真是人见人爱，花见花开啊!
