写一篇关于动物的作文用英语【精选20篇】

Dolphin is my favourite animal.

It is one of the most precious animals. Their bodies are very long, about one zhang(丈). Dolphins live in the sea. They live on fish, shrimps and so on.

Dolphins are very friendly and peaceful. They never attack people. Instead, they have saved many people in danger in the past years. How helpful the dolphins are!

Dolphins are very clever. People often train them so that they can give a dolphin show which brings people a lot of happiness and joy.

Unluckily, the number of dolphins is getting smaller and smaller. Because of water pollution, there is less and less space for dolphins. Many people make money by hunting dolphins. If we don’t protect them, maybe we’ll lose our good friends one day. As a student, I hope more and more people should take actions to protect dolphins.

Nowadays more and more people keep animals as pets; they treat them as their family members. But there is someone who likes to torture animals. They do this for some reasons: they don’t like animals, they get fire or they are just not happy. Some people think it’s fine to torture animals, because people are suffering more pressures than before; they need some way to be relaxed. In my point of view, I think animals deserve better.

In the first place, some animals are kept as pets in family. They are a part of it, like dogs or cats. They can bring people happiness. Lost of parents have pets for the reason that it could help their children learn to care about others; they think it’s a good way to teach children to be a good person. For the single people, pets could be a good companion, especially for an introvert, they prefer to talk to an innocent animal better than a person who is wearing a mask.

In the second place, people who are like to torture animals may have some psychological problems. If someone is suffer too much pressure that they couldn’t breath, they should find a healthy way to release it, for instance, they could go to swimming, jogging or climbing. They don’t have to hit pets to release their anger. Some people even cut pet’s ear or claw or had pet’s eyes gouged out. This is really sick; it’s hard to understand that what kind of people would hurt an animal when they are look into their innocent eyes.

In sum, animals is a lovely creature that made by god to bring happiness to human beings. People should treat them better than torture them.

现在越来越多的人把动物作为宠物,他们对待他们的家庭成员。但有喜欢虐待动物的人。他们这样做有一些原因:他们不喜欢动物,他们得到火灾或他们只是不开心。一些人认为它很好折磨动物,因为人们的痛苦比以前更多的压力,他们需要一些放松的方法。在我的观点,我认为动物应该得到更好的。

首先,一些动物作为宠物饲养在家庭。他们是其中的一部分,像狗或猫。他们可以给人们带来幸福。失去父母的养宠物的原因,它可以帮助他们的孩子学会关心别人,他们认为这是一个好方法教孩子成为一个好人。单身人士,宠物可能会是一个好伴侣,尤其是对于一个内向的人,他们更喜欢跟一个无辜的动物比一个戴着面具的人。

第二,喜欢虐待动物的人可能会有一些心理问题。如果有人受到太多的压力,他们无法呼吸,他们应该找到一个健康的方式来释放它,例如,他们可以去游泳,慢跑或爬山。他们没有达到宠物释放自己的愤怒。有些人甚至把宠物的耳朵或爪或宠物的眼睛剜了。这是真的病了,很难明白,什么样的人会伤害动物当他们看着他们的无辜的眼睛。

总之,动物是一种可爱的动物,由上帝给人类带来幸福。人们应该对待他们比折磨他们。

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.

Dear Lily:

I think you had better feed a hamster,the trediest kind of pet these days is the small hamster. People like them because they are quiet and clean. I have a hamster named Tom,it’s very cute and easy to take care of,and it’s cheaper than rabbits or cats,so I bought it. She’s my best company,because she reads books and litens to music with me every night.However,life with a hamster isn’t always perfect,she sometimes noisy at night ,she love sleep all day,too. So,sometimes she is very boring! How do you think?

It was a fine day today and the sun was bright. I visited Beijing Zoo with my classmate, He Song. The animals were so interesting that all the people loved them. When a bear asked for some food by waving its ann, a visitor threw something to it. At once I went up to him and said without thinking,Dont do that. Its bad for it. If you really love them, take good care of them. His face turned red and answered he wouldnt do that again.

今天是个风和日丽的好天，我和同学贺松去了北京动物园。动物们是那么可爱，大家都非常喜欢它们。一只熊挥动着胳膊向人们要吃的，一个游客就投进去了什么东西。我想都没想就走过去说：“不要那样做。你的做法对它们没好处。如果真的喜欢它们，就应该爱护它们。”他的脸红了，并且回答说他不会再那么做了。

As the new year is coming, many families plan to go the zoo and have fun together. But recently, a tragedy happened in the zoo, a man was bitten by a tiger. The public scared, then later the truth came out that the men tried to skip buying ticket and he went across the limited line. The animal has their nature. Once they are under threat, they will do the horrible thing. If the visitors behave themselves well and do as the tips, then the tragedy won’t happen. But still a lot of people scream and try to throw away the food to the animals, which do harm to the animals. It is everybody’s duty to protect animals.

随着新年的来临，许多家庭计划一起去动物园玩。而最近，动物园里发生了一场悲剧，有人被老虎咬伤。大家都害怕起来，结果真相是那个人试图逃票，还越过禁止线。动物都有自己的本能，一旦受到威胁，他们就会做可怕的事情。如果游客遵从提示、约束自我，那么悲剧就不会发生。但是仍然很多人会大喊大叫，试图扔食物给动物吃，这对动物是有害的。保护动物是每个人的责任。

Live in the dense forest, many small animals. Every spring they hold a grand acrobatics competition. This years competition is very busy, small animals came to the venue early and took out his magic sauce.

First of all, beautiful peacock dances: he head high head, chest, belly on tail slowly, gently shake the feathers; His head from time to time is to the east, west, the fan tail like a gorgeous colorful dress, and tightly attracted the audiences eyes.

Wood ball turning around, but he firmly when local, not nervous. You see, his right hand on the waist, left hand waving to the crowd. His wonderful performance won applause...

The annual acrobatics competition ended, but the animals good show, for a long, long time also by forest residents are talking about.

茂密的森林里，生活着许多小动物。他们每到春天都要举办一次盛大的杂技比赛。今年的比赛更是热闹非凡，小动物们早早来到会场，纷纷拿出自己的绝活儿。

首先，漂亮的孔雀表演舞蹈：他昂着头、挺着胸，慢慢地展开尾巴，轻轻抖动着羽毛;他的头时而摆向东、时而摇向西，那条扇子似的尾巴像一件绚丽的七彩衣，紧紧 吸引着观众的眼神。

接着，小狗表演 荡秋千。只见他纵身一跃，跳到秋千上，双手紧紧抓住绳子。他先是轻轻地荡了几个来回，然后就使足劲，直冲云宵，他高超的动作看得人眼花缭乱。

一年一度的杂技比赛结束了，但动物们精彩的表演，很久很久还被森林的居民们谈论着。

Many animals are in danger of dying out. As is clearly shown in the bar chart, the kinds of wild animals have decreased sharply in the past decades. With 30,000 wild animals reduced on average each year, there were only 1.5 million left till 2010.

There are several reasons accounting for this problem. Apart from the polluted environment and natural disasters, illegal killing is an important reason. Human beings are making attempts to hunt wild animals for fashion and a big profit, which can be seen vividly from the right picture. This has resulted in a sharp decrease in the number of animals.

In my opinion, it is high time for us to take quick action to protect them. A national public campaign should be launched to give animals a good living environment. In addition, the government should pass some firm laws to forbid abuse killing. Only in this way can we live in harmony with wild animals.

许多动物都面临灭绝的危险。显然这个柱状图所示,野生动物的种类急剧下降在过去的几十年。每年平均30000野生动物减少,只剩下150万到2010。

占这个问题有几个原因。除了环境污染和自然灾害,非法捕杀是一个重要的原因。人类正在试图猎杀野生动物对于时尚和一个很大的利润,从右边可以看到生动的画面。这导致了动物的数量急剧减少。

在我看来,我们是时候采取快速行动保护他们。国家公共活动应该推出给动物一个良好的生活环境。此外,政府应该通过一些公司法律禁止虐待杀害。只有用这种方法我们才能与野生动物和谐相处。

When it comes to animals, people just want to go back to kill to eat their meat and scraping their fur to make money, but never thought of human is because the treatment of animals, such as disorderly turn reduces day by day the kinds of animals, and some animals have arrived "endangered" according to news reports: wild Siberian tigers in China less than 500 only, and only about 47 to 690000 African elephants, the Yangtze finless porpoise is less than 1500 head, while the eastern cougar extinct, bering sea cows also extinct, also make the biosphere and suffered severe damage to the food chain, which are human crimes committed in the earth, we need to protect these beautiful creatures, to protect the biosphere, protect the food chain.

In order to protect the animals; Countries in the region to build the zoo; In addition, in some areas also establish nature reserves and scenic spots. Also has the provincial forestry bureau and the municipal forestry administration in provincial regions; And in the forest with police station; Countries with the level of national grade a few animals in the animal kingdom; Separately promulgated and issued by the state laws to protect animals and files.

If human repeat ones mistakes, then the home to the survival of humans will be destroyed by human hands.

We have to live like animals, if we kill all the animals on the earth, eventually hurt ourselves.

We is a friend of animals, animals are our friends, is a friend of survival in survival.

We want to protect animals, let them give us the benefit, its our duty to protect animals, so it is urgent to protect the animals.

I come to the conclusion that a rong shame: "in order to protect the animals, ashamed of killing animals".

一说到动物，人们就想捕回去杀死吃它们的肉和刮下它们的皮毛来赚钱，可是人类万万没有想到的是由于乱捕滥杀等对待动物，使得动物的种类一天天减少，而有的动物已经到达“濒临灭绝”据新闻报道：野生东北虎在我国不足500只、而非洲象只有约47至69万只、长江江豚不到1500头、而东部美洲狮已经灭绝、白令海牛也已经灭绝、也使生物圈和食物链遭到严重破坏，这都是人类在地球上一一所犯下的罪行，我们要保护这些美丽的生灵、保护生物圈、保护食物链。

为了保护动物;国家在各个地区建立动物园;除此之外，在一些地区还建立自然保护区和自然风景区;另外还在各省各地区设有省级林业局和市级林业局;还有在森林设有森林派出所;国家在动物界设有国家几级动物的级别;国家还分别颁布和颁发了保护动物的法律和文件。

如果人类一错再错下去的话，那么这个人类赖以生存的家园就会毁于人类手中。

我们和动物一样都要生活，如果我们把地球上的动物全部杀死，最终伤害了我们自己。

我们是动物的朋友，动物也是我们的朋友，是生存在赖以生存的朋友。

我们要保护动物，让它们给我们造福，保护动物是我们的责任，保护动物刻不容缓。

我总结出一条一荣一耻：“以保护动物为荣，以捕杀动物为耻”。

In our common home - the earth, life with a lot of animal, which animal do

you like? Anyway, my favorite animal is our most loyal friend - a dog.My

favorite is my neighbors dog that Beijing BaGou yuan yuan and collie handsome.

They play together every day, it is a good friend of a stick dozen not

scattered, I also like them, they saw I was shaking his tail towards

me.Handsome shape tiger is big, the body is about more than 60 centimeters

long. Two leg, capable to my shoulders, his eyes, nose, mouth, ears are much

older than yuan yuan, I most like to see him running figure - curly float in the

sky, like a nice horse. I often and yuan yuan, running with the handsome, every

time is handsome first, second, I am the third round. Can literally, handsome

running faster than thoroughbred horse. Average dog ran up, send out "clicking"

sound, but handsome rans voice is very small, not carefully is inaudible. The

appearance of the handsome run is also very handsome, curly, bow shaped body. If

you want to use a word to describe talent, that is: handsome. If you use a word

that was impeccable.Compared with the handsome, round shape is much smaller,

only 30 centimeters in length and a half smaller than talent. The meaning of his

name from his eyes, it is too round. Like a shiny black stones. And his legs are

very round and round this is name. And his legs are very short, so even if he

runs, casting its foot also run fast, but I still like him very much the kind of

simple and lovely.This is what I like animals, do you like?

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。

Recently, our efforts to protect wild animals was questioned by the public,

because the news is keep reporting that more and more wild animals was killed by

human beings, especially the very precious one. Innocent animals was dead for

their meat, fur and tooth, it was just used to fill up human beings desire. In

my point of view, the wild animals were protected effectively still has a long

way to go.

Firstly, people should try harder to make a better place for animals. The

land where the wild animals live was deprived by human being. For hundreds

years, people cut the trees to make land for their living and farming, wild

animals homeland was took, they have no choice but run away. What is more,

human beings break the food link in nature; wild animals can not find enough

food to keep alive. There is no doubt that the destruction of nature has become

a big problem to kill wild animal, for instance, a polar bear was starved to

death because of the greenhouse effect, the ice was melt away, the seadog and

fish that polar bear like to eat are far away from them. For those reasons,

people should protect the environment first if they want to protect wild animals

effectively.

Second, no buying, no killing. Some rich people like to wear fur coat, they

treat it as a status symbol, especially for rich woman, they think animal fur is

beautiful and warm, they will never consider that the fur they wear for years is

the skin that animal wear for their whole life, and they knew how bloody when

people took the fur from animal but they choose to ignore it. If people do not

buy the fur and tooth, lots of wild animals will be survived.

In sum, wild animals are our friends, we should give back and protect their

homeland, and stop buying their body part, or our future generations will see

them in zoo and museum.
