我没看到它们的耳朵，但是小鸡不可能没有耳朵。如果没有耳朵的话，那我们走过去时，它们怎么会偏着脑袋朝我们瞧呢?

I dont see their ears, but chickens cant have ears. If there were no ears, how could they lean on our heads when we walked by?

Mother said, the newly hatched chickens can only eat small grains of rice, can not eat millet or corn, but also often give them water. If they had worms, they would have grown stronger.

there are many kinds of animals in the world,but not only the humans.we live in the same world,and we should be friends.as everybody knows,the humans are the rulers of the world today,so we should protect our friends--the animals!

but how to protect them?as first,i think we must stop killing the rare birds and animals,especially the young ones.the second,we have to protect the environment,to make the sky blue,to make the grass green,to give the animals a comfortable space to live.it`s not only for the animals but also ourselves.the last,we should tell more and more people why and how to protect the animals,make everyone do this.

Many wild animals are facing the danger of extinction， because the environment that they are living in has changed greatly。 For example， with the developmet of cities， the using of insecticide and serious pollution， their living areas have become narrowcr and narrower。 Many of the wild animals， now are confronted with food crisis。 At the same time， man is killing off species just for getting their fur， skin， horns， teeth and meat。

In order to protect our resources of ecology， people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty。 There fore， measures of the following should be taken： pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life， reserves。

Only if we human beings take some drastic measures can wild animals be preserved。

关于动物的英语作文三

Panda is one of the scarcest animals. People in the world like it very much. There used to be many pandas in China long ago. As the balance of nature was destroyed and the weather was getting warmer and warmer, pandas became less. But at present, the number of pandas is increasing year by year. There are now so many pandas that some are being sent to other countries so that people there can enjoy them.

Nowadays, the biggest nature park for panda in China is in Sichuan. There is a research centre for nature and wild life there. Scientists hope that one day they will have enough pandas to be set free and let them live in the wild again.

Nowadays, with the improvement of the people’s living standard, some people form a habit of raising small or domestic animals as pets. Some raise small dogs or cats as their pets while others raise various birds or fishes as their pets. There are still even some people raising snakes and other unusual animals as their pets.

Does anyone have the same opinion of raising animals as pets? No, some people object to the idea of raising animals as pets. To them, animals have their own right to live a natural life like human beings. On the other hand, the way people raise animals as pets have a negative influence on the surroundings such as dogs’ barking at midnight, dogs’ chasing people on the street and so on. What’s more, some animals will transmit some diseases.

In my opinion, I do not like the idea to raise animals at pets. Animals have their own right to lead a life as they like. We should not deprive them of their natural right. In this way, we will live in a peaceful world in harmony with the other living creatures.

如今，随着人们生活水平的提高，有些人养成了饲养小动物或家畜作为宠物的习惯。一些养小狗或猫作为他们的宠物，而其他人饲养各种鸟类或鱼类作为他们的宠物。甚至还有一些人饲养蛇和其他不寻常的动物作为他们的宠物。

任何人都有相同的意见，饲养动物作为宠物吗?不，有些人反对将动物作为宠物饲养。对他们，动物有他们自己的权利，生活像人类一样自然。另一方面，人们饲养动物作为宠物的方式对环境有负面影响，如狗的叫声在半夜，狗追逐人在街上等。更甚的是，有些动物会传播某些疾病。

在我看来，我不喜欢养宠物。动物有他们自己的权利，过他们喜欢的生活。我们不应该剥夺他们的自然权利。这样，我们将生活在一个和平的世界中，与其他生物和谐相处。

Some people think that human needs for farmland, housing, and industry are more important that saving land for endangered animals.

Do you agree or disagree with this point of view? Why or why not?

Use specific reasons and examples to support your answer.

In the past, there have been many endangered animals. Now they are extinct. Does it matter? Has our environment been affected by their absence? Has the quality of our own life been changed? The answer to these questions is “Yes.”

Yes. It does matter if we destroy an endangered species habitat to develop more farmland, housing or industrial parks. There is a delicate balance of nature. If one small part is removed, it will effect all the other parts.

For example, if certain trees are cut down, bats will have no place to roost. If they cannot roost, they cannot breed. If there are no bats, there will be no animal, or bird to eat certain insects that plague our crops.

Yes. Our environment has been affected by the absence of certain animals. Certain flowers are pollinated by butterflies, which migrate from Canada to Mexico.

Some of the breeding grounds of these butterflies were destroyed. Now these flowers are disappearing from certain areas. We will no longer be able to enjoy their beauty.

Yes. The quality of our life has been changed America used to be covered with giant trees. Now we have to visit them in one small park.

Rain forests around the world are being cut down to make room for humans. We will never be able to see or study this fragile ecosystem.

I would encourage us humans to look for other alternatives for our farmlands, housing, and industries. We have alternatives; the animals do not.

Everybody likes a small animal! Such as dogs, cats, turtles and so on. My home have a pet dog. He is a little yellow, his whole body is yellow. He has a pair of watery big eyes. Yellow is a little male dog. When he grow up, can help us tube of the house.

One day, the little yellow swept away.com by the bad guys to catch, I was so sad. I want to, I later cant play with you, a little yellow. A few days later, huang came back again, I dont mention how happy heart.

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

Animals Need Protecting

There are more and more endangered animals at present，so how to protect them has been our task of top priority 。 Its wrong for people to hunt animals for their meat and feather，for they are our good friends。We should protect them instead of killing them。Giant pandas，which are one of the endangered animals，live in the forests and live on bamboo lealves。They can just live safely in the natural protection zones。We should stop killing animal and protect them。

I like the small animals is pure white cat, it whole body white hair like snow let me very love, its eyes narrowed into a crack during the day, night round, like two emeralds. His ears have been up, as long as you move, his ears will move; His hearing is very agile, as long as people walk on by, it will be called "meow"; Its teeth are very hard, and spiky, eating up to very easily, I like it very much.

我喜欢的小动物是纯白色的猫，它全身白似雪的毛让我无比喜爱，它的眼睛白天眯成一条缝，晚上圆溜溜的，活像两颗绿宝石。他的耳朵一直翘着，只要你动一下，他的耳朵就会动一下;他的听力十分敏捷，只要有人轻轻走过，它就会“喵喵”的叫;它的牙齿很坚硬，又尖又长，吃起东西来十分轻松，我很喜欢它。

记着有一次，我的哥哥到我家来玩，小猫无比热情，一直冲哥哥“微笑”。哥哥见他这么可爱，便拿出一根很粗的毛线，要知道猫最喜欢玩毛线了，哥哥提着毛线，小猫也跟着走，毛线从拐弯处过去，猫一下冲过去，没有抓到，自己倒扑了个空，我和妈妈哈哈大笑，猫有点生气，哥哥换了一块布，过了拐弯处，小猫冲去，又扑了空，这下哥哥成了“斗猫士”了。哥哥又把五个凳子摆成一排，把毛线放在凳子口，小猫一下冲过去，奋力咬住了毛线，我为它欢呼，为它高兴。

冬天来了，我给小猫盖了一个温暖的窝，它非常高兴。每当我放学回家走在楼梯上时，小猫就卧在沙发上等我，我一进门，它脸上笑成了一朵花。见我买了吃的给它，高兴得舔着我的手，无比热情!

有天，爸爸给我说：“你看哪，狗可是忠臣，猫可是奸臣。”我着急了，忙说：“猫是我最喜欢的动物，它才不是奸臣呢!”妈妈跑过来当裁判，规定每人写出喜欢猫或狗的理由5个，然后评高低。我的笔刷刷写着，1、我喜欢猫;2、小猫的毛很光滑;3、猫对我很真诚;4、猫非常可爱;5、猫非常机灵。刚写完，我抬头看看爸爸，哈，他才写了两个，我们都交了卷后，裁判以爸爸写的字多为由，宣布爸爸胜利。我很不服气，我相信，我会将小猫的可爱永远扞卫下去!

小猫，淘气、可爱，他给我的生活带来了快乐，无论怎样，我最喜欢的动物就是小猫!

地球上一片生机勃勃，到处都是可爱的生命。生命需要我们去珍惜，我们去保护。

人有生命，动物也有生命。

公元前出现了猿人，对于现在，有些人认为，他们只是会群居的动物。其实，说这话的人，也就是他们演变而成的。

从古至今，许多人曾不择手段的捕杀动物。就拿以前的广东人来说吧，他们最喜欢生吃野生猴脑了，那时，他们把活生生的猴子的头盖骨去掉也不觉得残忍。可怜了那些猴儿啊……

现在，在动物园里，我们往往会看见“请不要喂食”的标语。就是为了让旅客们别投搞恶作剧。一次，一只动物就是吃了旅客投的塑料袋，生病了。

所以，呼吁大家，请保护动物，现在野生动物越来越少了让我们的家充满生机吧!

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。

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!
