关于动物的作文英语（经典20篇）

animals are natural resources that people have wasted all through our history. animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. thousands of kinds of animals have disappeared from the earth forever. hundreds more are on the danger list today. about 170 kinds in the united states alone are considered in danger.

why should people care? because we need animals, and because once they are gone, there will never be any more.animals are more than just beautiful or interesting. they are more than just a source of food. every animal has its place in the balance of nature. destroying one kind of animal can create many problems. for example, when farmers killed large numbers of hawks, the farmers` stores of corn and grain were destroyed by rats and mice. why? because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

luckily, some people are working to help save the animals. some groups raise money to let people know about the problem. and they try to get the governments to pass laws protecting animals in danger. quite a few countries have passed laws. these laws forbid the killing of any animal or planton the danger list. slowly, the number of some animals in danger is growing.

科学家们把现存的人类已知的动物分为无脊椎动物和脊椎动物两大类。科学家已经鉴别出46900多种脊椎动物。包括鲤鱼、黄鱼等鱼类动物，蛇、蜥蜴等爬行类动物，青蛙、娃娃鱼等两栖类动物，鸟类以及红熊猫等哺乳类动物等。下面是小编为大家精心推荐的有关于动物的英语作文，希望大家喜欢。

It is one of the most precious animals. Their bodies are very long, about one zhang. 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.

However, the leaders separate into two factions soon after. As a result, Snowball is expelled by Napoleon as a betrayer. Although many animals remember that Snowball is a brave leader, they firmly believe they were wrong and Snowball is a bad animal indeed after brainwashing Napoleon offered. What’s more, the Seven Commandments of Animalism had also been changed. Finally, the Animal Farm becomes quite different from what they hope it to be at the beginning.

Researchers looked at climate change effect on the Arctic Sea and calculated the likelihood of this projected population drop is 71 percent.

我家有一只既可爱又淘气的小白狗，它叫小白。

小白贪睡极了。一到中午，它就会找个暖和的地方，无忧无虑地睡起了大觉，不管你怎么叫它，喊它，它都像没听见似的，左耳朵进，右耳朵出，一点也不理睬你。

有一次，在它睡觉时，我偷偷地把它的食物藏了起来，它醒时，找不到了美餐，简直是像热锅上的蚂蚁，又像沸腾了的饺子，心急如焚，“汪汪”地叫个不停，似乎是在喊“我的事物呢?我饿得不行了!”

忽然，它看见我得意洋洋地走了过来，像福尔摩斯一样，似乎有了答案，便虎视眈眈地看着我，过了一会儿，迅速地跑过来，咬住了我的裤子，拼命地往后拽，我也不干示弱，使劲地往前走，唉，由于小白的牙齿锋利，所以我被它拉了过去。

小白再三“恳求”我，眼睛里露出了焦急地神情，我无可奈何，把藏在柜子里的食物给了它。

小白顿时像找到了家的小狗一般，悲喜交集，好象在说“谢谢你，好主人!”

怎么样，这就是我和小白之间有趣的事!

Everyone knows animals are our friends. So we should be friendly to them.

But some people kill the rare animals, such as pandas, golden monkeys and so on in order to get money.

It will cause these animals to disappear soon.

I think our government should punish those people severely who kill the rare animals.

It is our duty to protect the endangered animals.

I like dogs, because they are man’s good friends.

They can do many helpful things to us, such as guarding our houses, greeting guests, helping the police, and so on.

Some trained dogs can even lead the blind people and save people’s lives. So they‘re treated as our family members.

I hope someday dogs will be in great harmony with human-beings.

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?

我最喜欢的小动物是小猫，我们家就养了一只小猫，它是邻居送过来的。因为现在那只小猫已经死了，所以我会经常想起它。

My favorite little animal is a kitten, and we have a kitten in our house. It was sent by a neighbor. Because the kitten is dead now, so I often think of it.

小猫长得很漂亮，他有一身雪白的毛，爪子下的肉垫可以使他走路没有一丁点声音。最独特的是他的眼睛：一只眼睛是蓝色的，另一只眼睛是绿色的。蓝眼睛像蓝宝石，绿眼睛像绿宝石。

The kitten was beautiful. He had a snow-white coat, and the pads under his paws made him walk without a single sound. The most unique is his eyes: one eye is blue, the other eye is green. Blue eyes are like sapphires, green eyes are like emeralds.

小猫很贪吃，有时一斤重的鱼不一会儿就“消灭”了。有一次，妈妈做了一碗鱼汤。小猫跳上桌子，津津有味的吃了起来。正在吃的时候，它被我发现了，于是我狠狠的教训了他一顿。小猫耷拉着脑袋，好像在说：“我再也不敢了。”我立刻笑了。

Kittens are voracious, and sometimes a pound of fish will soon be wiped out. Once, my mother cooked a bowl of soup. The cat jumped onto the table and ate it with relish. While I was eating, it was discovered by me, so I gave him a hard lesson. The little cat drooped its head as if to say, "I dare not."." I laughed at once.

现在那只小猫已经死了，从那以后，我每次见到小猫，都要和它嬉戏一番。小猫，你到底去了哪里了呢?

Now that kitten has died, since then, every time I see a kitten, I have to play with it. Kitty, where the hell have you been?

Why should people care? Because we need animals, and because once they are gone, there will never be any more.Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or planton the danger list. Slowly, the number of some animals in danger is growing.

Do you know what kind of animal I like most? It’s monkey. Monkey is a kind of lovely animal.

Many people like monkeys very much. Generally, monkey has small body covered with fur. Some kinds of monkeys have two big eyes and ears and a long tail. I can see them on TV or the zoo.

Every time I go to the zoo, I will go to see them.

Monkeys often stay in trees and jump between them. They are so lively and favorable. When they are happy, they will act for visitors. It’s very funny.

We need to protect wild animals, because we protect wild animals, wild animals will be very friendly to us.

Like the swallow, swallow can help us to eat the pests in the field. If we human beings killed to catch them, they will eat mosquitoes that often to scratch faze us, let us better life? Without the swallow around us become many insect pests, these pests have great harm to our human!

I have an example. For example the frog, the frog can also help us to eat the pests in the field, can be said to be the police in the field. Once we kill them, not the frog, the pests in the field more and more, pest constantly eat vegetables, dont we will have a good harvest?

I have an example. Such as w, w is a doctor in the forest, it can help us to eat the pests in the tree, the tree back to health. We killed them, pests will be more and more trees, trees will slowly decrease. No trees on earth, floods, earthquakes.

My last an example. Such as owls, catch rats, the owl is good for us human beings, human is often hunt them. No owls, voles will increase. Rats ate the crops and vegetables is more, we human beings did not have a good harvest.

So, we need to protect more than animals. At the same time, we also need to protect other wild animals!

我们要保护野生动物，因为我们保护野生动物，野生动物对我们人类也会很友好。

比如说燕子，燕子能帮我们把田里的害虫吃掉。如果我们人类杀害捕捉它们，它们会吃掉那些常常来搔扰我们的蚊子，让我们更好地生活吗?没有了燕子，我们的周围变得很多害虫，这些害虫对我们人类有很大的坏处呀!

我还举个例子。比如说青蛙，青蛙也能帮我们吃田里的害虫，可以说是田里的警察。我们支捕杀他们，一旦没有了青蛙，田里的害虫越来越多，害虫不断地吃菜，难道我们会有美好的丰收吗?

我还举个例子。比如说啄木鸟，啄木鸟是森林中的医生，它可以帮我们吃掉树里的害虫，让树恢复健康。我们杀害它们，树木的害虫会越来越多，树木会慢慢地减少。地球上没有树，会发洪水、地震。

我最后举个例子。比如说猫头鹰，猫头鹰捉田鼠，是对我们人类有好处的，人类却常常捕猎它们。没有猫头鹰，田鼠会增加。田鼠吃的庄稼和菜就更多了，我们人类一样没有好的收成。

所以，我们要保护以上的动物。同时，我们还要保护其他的野生动物!
