写一篇关于动物的作文英语作文（优秀20篇）

Animals are friends of human beings, everybody is responsible for animal protection, we should take good care of them. Because, there are a lot of insects are beneficial to human. For example: the bee, it is industrious, very early in the morning to go out honey, again and again. In the dark, after the bite honey, non-stop to adopt to carry on the processing of honey. The appearance of the bees and ordinary, life is very short, only about 3 months, Can it all his life not rest, work diligently, and them nothing in humans, but for people to make sweet and delicious, nutritious, honey can cure sickness.

And the frog, the frog is covered with green clothes, two big eyes, like two stars glittering and translucent and transparent glass ball, it hid in the field, only eat insects, protect crops. Two a push with its back when it catch insects, a jump, nimbly hind legs up, jump up high, long tongue out, like a vacuum cleaner quickly eat insects to the stomach. But we humans can use them as delicious food on the table.

There are many lovely animals, my favorite is the giant panda. The giant panda is our precious animals, my mother told me that the giant panda is a national treasure of our country! Long giant pandas are cute, chubby, plump, start to counteract a, particularly funny. Its head and body are white, only the rim of the eye, ear, and the shoulder is dark brown. Especially that a pair of black rim of the eye, long in white face, like wearing a pair of sunglasses, plus the clumsiness and start to look in all directions, looks like a little gentleman.

You look! They are adorable, they are our humans good friends, how are we going to have the heart to hurt them?

动物是人类的朋友，保护动物人人有责，我们应该爱护它们。因为，有很多昆虫都对人类有益。比如说：蜜蜂，它很勤劳，每天早上很早就出去采蜜，一次又一次。到了天黑，吃几口蜜糖后，就马不停蹄地对采来的蜜进行加工。蜜蜂的外形并不起眼，生命也很短暂，只有3个月左右;可它一生都不休息，勤勤恳恳地工作，它们对人类毫无所求，却为人们酿造了甘甜可口、营养丰富、可医治病痛的蜂蜜。

还有青蛙，青蛙披着碧绿的衣裳，两只大眼睛，像两颗晶莹透明的玻璃球，它藏在田里，专吃害虫，保护庄稼。它捉害虫的时候两条后腿一蹬，一纵身，敏捷地将后腿一蜷，跳起老高，长长的舌头一伸，就像一个吸尘器一样转眼就把害虫吃到肚子里去了。可是，我们人类却把它们当成美味佳肴摆在餐桌上。

还有许多可爱的动物，我最喜欢的是大熊猫。大熊猫是我国珍贵的动物，妈妈告诉我大熊猫还是我们国家的国宝呢!大熊猫长的很可爱，胖乎乎、圆滚滚的，走起路来一摇一晃的，特别逗人。它的头部和身体都是白色的，只有眼圈、耳朵和肩部是黑褐色的。特别是那一对黑黑的眼圈，长在白白的脸上，像是戴着一副墨镜，加上那笨拙的动作和走起路来东张西望的神情，显得像个小绅士。

你瞧!它们多么可爱，它们是我们人类的好朋友，我们怎么忍心伤害它们呢?

Orcas are not related to whales at all, other than being ocean-dwelling mammals. Rather, they are close kin to dolphins. While it was believed that they were a single species, recent research indicates that they may, in fact, be comprised of several different species of Orca. You can find them in every ocean in the world, though they tend to favor the colder waters around Antarctica and the North Atlantic or Pacific. The only predator they possess is humankind. While theres a deadly standoff between the two species, Orcas proliferate in the wild, and have an incredible life span. The males usually live as long as sixty or seventy years, while the females—who are excluded from the sometimes-violent competition for mates—may live a hundred years or more in the wild.

虽名虎鲸，但不同于海洋其他哺乳动物，非鲸目，海豚科的近亲。此前一直认为虎鲸只有一种，但最近的调查显示虎鲸种类繁多。部分虎鲸会终年停留于南极、大西洋北部和太平洋等温度较低的海域，但总体来看，它们的活动范围几乎覆盖全世界水域。它们堪称海上霸王，唯一的天敌也只有人类了。虎鲸全年都可以交配，数量庞大，雄鲸的平均寿命在60到70年左右，野生雌鲸不同于雄鲸经常参与猎杀食物，寿命可达100年甚至更长。

Theyve been observed reaching speeds of around 30 miles per hour, although some Orcas may utilize much greater bursts of speed, based upon their favored prey. Resident pods in the Pacific Northwest have shown a decided preference for salmonids—specifically, Chinook salmon. This presents a conflict with the goals of companies that rely on high yields of salmon for profit. Several communities of killer whale seem to favor beach and ice floe ambush approaches, snatching seals and walruses or even sea birds from their resting places. Others, located in the Southern Hemisphere, take up the challenge of hunting sharks in the open sea, as well as feeding on species of rays and other fish abundant in the cold southern waters.

虎鲸约时速30英里，当然也有爆发力更强的，为了追捕中意的猎物，时速可以更快。太平洋西北海域的虎鲸族群偏爱三文鱼，尤其是大鳞三文鱼。这就和沿岸经营三文鱼生意的公司产生一定的利益冲突。虎鲸族群喜欢在浮冰区伏击猎物，捕杀海豹、海象或者在这里歇脚的海鸟。在南半球海域里，有些虎鲸还会在公海里捕杀鲨鱼，也会以鳐和其他鱼类为食。

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 bee 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。

几天前，妈妈将一只小猫带回家，我给它起了一个美丽的名字叫“咪咪”。

“咪咪”除了四足和鼻子是白的，其余都是黑的，看上去，好像在胸前打了一个白领结，你能想象出它是什么样了吗?

每天早上，它总是起得很早，然后跳到我的床上，把我叫醒，我们坐在桌前吃早餐时，它会从桌下轻轻爬到我们的膝盖上，好像在说：“我也想吃东西。”

“咪咪”喜欢躺在地板上晒太阳，它觉得很舒服。这样做时，它看起来更加可爱。

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.

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。

Earths biological diversity is being fast decline of many species facing extinction.Threat to the survival of wild animals and plants is a major factor in habitat loss， business development， and wild animals and plants and their products in international trade.Resources are limited， it is necessary for the endangered species， to propose specific measures of protection level.We can formulate the corresponding endangered species laws， application to establish nature reserves， endangered species breeding centers， means of conservation biology， endangered species， the implementation of in situ conservation and ex situ conservation.At the same time， we must restrict international trade in Endangered Species of Wild Fauna and Flora， to make laws to protect endangered species。

there is only so much land on the earth, and so what we can do with it is limited. some people believe that human needs for farmland, housing and industry should come first, while others believe that some land should be set aside for endangered animals. i am of the opinion that we should reserve some land for the worlds animals for the following reasons.

first, mankinds need for land is constantly growing. if the demand is not checked in some way, humans will eventually develop all of the earths available land. at that time, mankind will have no more room to grow, and all the wild animals will have disappeared, as well as other valuable resources. second, humans are able to innovate and can use the land that they already possess in more efficient ways. animals are unable to do this. once their land is taken away from them they will die. third and last, endangered animals are an important part of the biodiversity of our planet. if they disappear, we cannot predict what the effect will be. therefore, we should treat such animals as a valuable resource to be protected.

to sum up, the worlds endangered animals are an important resource and we should protect them by setting aside some land for them. although mankinds need for land continues to grow, people are intelligent and inventive enough to put the land they have to better use. in this way, we can have enough land for farming, housing and industry, and preserve the biodiversity of the planet at the same time.

Dear classmates,

As we know, some animals are dying out for various reasons. There is no doubt that animals are our friends. With World Animal Day coming near, what should we do to protect animals?

First of all, we should forbid people’s killing animals at random. Second, we should do all we can to protect animals’ living environment. With their living environment destroyed, the animals will become extinct sooner or later. Third, we should try our best to make everyone realize the importance of protecting animals. In a way, protecting animals means protecting ourselves.

Dear classmates, let’s start now and make every effort to protect animals—our good friends!

If you ask me what my favourite animal.I can tell you pandas are my favourite.I like the pandas not only because they are one of the Chinas treasures,but also because they looks cute.

Pandas are very fat and hairy. They have two colours:white and black.The pandasd face,back and stomach are all white, their eyes nose legs and arms are all black.

There is a big tree behind the house a wild profusion of vegetation, there is a big bird, bird in the father mother and baby birds consisting of.

一天，我吃完饭来到后院散步，一只饥饿的小猫咪正往树上爬，它心想：我一定要吃掉树上这几只肥嫩的小鸟，就不用饿肚子了。它不怀好意的偷笑着，它一边笑一边爬。这一幕刚好被我看到了，我心想：不能让小猫伤害了小鸟一家。我顺手拿起一块石头向小猫丢去，小猫咪“喵”的一声吓跑了，小鸟一家得救了。

One day, I went to the backyard for a walk after dinner, a hungry cat climbing the tree, she thinks: I must eat the tree of the few fat birds, not hungry. Its a harbour evil designs laughing, laughing and climb it. This scene is just I saw, I thought to myself: dont let the cat hurt a bird.

If you see the using life of bridge, would you put down your hand gun; If you saw the dead ant kingdom by compatriots hero, would you put down your hands cut off the tools of ants.

In the summer, when you are running in the grass that you follow the foot to jump, do you know how many creatures will be gone from this world? I can responsibly tell you: you are the one feet for insects, equals eight pounds of C4 explosives! Eight pounds of C4 explosives can blow up a skyscraper! Can you imagine the?

The kinds of animals in gradually reduce, humans will get lonely; If we dont consciousness, is also want to use the machine to the zoo after animals? !

All of the young pioneers, please join me in calling for: take good care of life is the responsibility of the young pioneers, we should cherish life, protect animals!

如果你看到了那用生命搭成的桥，你会不会放下你手中的猎枪;如果你看到了那因同胞而死去的蚁国英雄，你会不会放下你手中灭蚁的工具。

是的，有时生命是那么的渺茫，渺茫的就象大海里的细沙。在夏天，当你在草丛中奔跑你那随脚一跳，你知道会有多少生物会从这世界上逝去吗?我可以负责任的告诉你：你那一脚对昆虫来说，就等于八磅C4炸药!八磅C4炸药可以一口气炸掉一座摩天大厦!你想象的到吗?

世界上平均每隔5分钟就会灭绝0.002种生物!地球在变暖，冰河在融化，我们美丽的地球将不再是一个家……动物的种类在逐渐减少，人类将渐渐变的孤独;如果我们还不觉悟，难道以后动物园也要用机器来制造动物吗?!

所有的少先队员们，请和我一起呼吁：爱护生命是少先队员应尽的责任，我们要珍爱生命，保护动物!

My favourite animal is the giant panda. The giant panda or panda is a bear living in central western and south western China. Most pandas live in Sichuan province. Pandas are adorable because of their distinctive black patches around eyes, ears and across its round body. Pandas are China’s national treasures. They’re among the world’s most adored and protected animals. Pandas are the star attractions in the Beijing Zoo. Experts say that despite their sweet public image, pandas are capable of attacking humans, especially if they feel threatened.

我们地球上有许多有益的动物，我们要保护它们。

There are many useful animal we on earth, we should protect them.

青蛙它是两栖动物。它生活在水里，或在靠近水边的地方。它专门吃田里害虫。它是农作物的“忠诚卫士”，是天然的捕虫机。一只青蛙平均一天吃70只害虫，一年能吃掉15000条害虫。

Frog it is amphibious animal. It lives in the water, or in close proximity to the waters. It is designed for field pests. It is the crop "loyal guards", is a natural insect catching machine. The average of a frog to eat 70 pests a day, a year can eat 15000 pests.

蜻蜓也很厉害。一只蜻蜓一个小时能吃20个蝇子或840只蚊子，真令人惊讶!

Dragonfly is also very powerful. A dragonfly one hour to eat 20 or 840 mosquitoes fly, really surprising!

燕子就更厉害了，它一只燕子一个夏天就能吃掉50万条害虫，燕子真是人类的好帮手!

The swallow is even more powerful, it is a swallow a summer can eat 500000 pests, swallow is a really good helper!

蜜蜂可以给我们人类带来甜甜的蜜，它也对我们有益的，我们要保护它。

Bees can give us to bring sweet honey, it is good for us, we must protect it.

地球上的有益动物，我们都要保护它们。

Useful animal on earth, we should protect them.

my pet is a toy bear. his name is small white. he is white. he has blue eyes and blue ears. his hands and feet are blue too.he is naughty.

he likes to make fun of me. he likes reading.

he is my good friend.

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。

In my home, there is a very lovely small animals, that is my mother gave me gift.

It was wearing a white and black clothes, looks like a gentleman; He has two small eyes, always hovering, at night, became "emerald"; Its ears are very cute, sharp, like a small mountain.

It is very naughty fish. Once I give it a fish, in your hands in it eyes want to, it also unmoved. I was a little angry said to it: "small cute, why dont you eat?" I think, it may be afraid to eat. So I deliberately turn head, have never thought, my hands move, see it quickly put the fish away, and then to eat with relish. Is really naughty!

It loved playing thread, of course. On one occasion, a bag of thread accidentally fell out. It saw the colorful small ball, curious. Then walk in the past, it is a little bit afraid of points with the hand a offline, see string, no reaction, then dare to play. But it more play more crazy, running around in the house, rolling on the ground, put in the room at sixes and sevens. Finally, get tired of it, to see so disorderly, hurriedly came, to my name, as if he were to me for help. Cant, dont want to be mother knew, had to help it to pick up the pieces.

Now you know who it is? It is a lovely cat. It is my friend! My joys and sorrows, will tell it, share my happiness with it. Every time I test is bad, they will also use wool rub my legs, as if to say again: "master, dont lose heart, trying to point, you will succeed next time!" When I get good grades, the kitten again as if to say: "dont be proud!" So, I have the "partners" and feel happy!

在我家里，有一只非常可爱的小动物，那是我妈妈送给我的礼物。

它穿着一身白黑相间的衣服，看起来就像一位绅士;他有两只小眼睛，总是转来转去，一到晚上，便成了"绿宝石”;它的耳朵也十分可爱，尖尖的，就像一座小山峰。

它吃鱼时很顽皮。有一次我给它一条鱼，拿在手上在它眼睛要来晃去，它也无动于衷。我便有点生气的对它说：“小可爱，你怎么不吃啊?”我想啊，它可能害怕不敢吃。于是，我故意扭转头，没想到，我手中一动，只见它飞快地把鱼叼走了，然后津津有味地吃起来。真是顽皮!

它最爱玩得当然是线团。有一次，袋子里的线团不小心掉了出来。它看见这五颜六色的小圆球，感到很好奇。便走过去，它有点害怕的用手点一下线团，见线团没什么反应，便渐渐敢玩了。可是它越玩越疯狂，在屋里跑来跑去，在地上滚来滚去，把屋里弄得乱七八糟。最后，它玩累了，看到这么乱，连忙走过来，对着我叫，像是在向我求救。没办法，要不想被妈妈知道，只好帮它收拾残局。

现在你知道它是谁了吗?它就是可爱的小猫。它还是我的朋友呢!我的喜怒哀乐，都会告诉它，与它分享我的快乐。每当我考试不好，小猫就会用毛蹭我的腿，好像再说：“主人，别灰心，在努力点，下次你一定会成功的!”当我取得好成绩，小猫又好像在说：“别骄傲哟!”所以，我拥有这个“伙伴”而感到开心!

Animals are mans most loyal friend, please dont hurt them.

I am particularly fond of small animals,. I think, they are mans most loyal friend. So, when I see others to dispose of animals, in the heart can not help but sad. My dream is to people and animals live in peace.

Now people are like to eat dog meat hot pot, I dont understand. A dogs life, it is to his own master, dont just because it is old, useless, and denied the value of its existence. This is not possible! People will also newborn puppies thrown into the lake, trash can, they are discarded, it is no good. Everyone has the right to existence significance and value, even if is a person, also not qualified to deprive their lives.

I have witnessed the cat after being hit by a car fly. The distorted face telling the pain of it. Its blood, viscera was hit from in vitro. Although the rain wash away the traces of blood, but every time I go there, mind will automatically jump out of the scene, think of the cat that broken beyond recognition, think about it before he died not look in the eyes...

Since then, I was in my heart silently vowed, to do their own efforts, to protect small animals, at least, dont let them innocent caused the death.

I think, in the future, I will set up a "happy family", there will be dedicated to adopt the stray animals, if the man willing to adopt, I will also be given to him. In this way, those who stray cat, stray dogs have a warm home. I will also for those precious endangered animal donations, not completely destroy them.

Perhaps, so I am very silly, very silly, but I am willing to do that silly to worry about in others eyes puny little animals.

If you also like me "stupid", let us firmly "silly". Because they are lovely.

动物是人类最忠诚的朋友，请不要伤害他们。

从小，我就特别喜欢小动物。我觉得，它们是人类最忠实的朋友。所以，当我看到别人随意抛弃动物时，心中不禁很难过。我的梦想就是人们和动物和平相处。

现在人们都很喜欢吃狗肉火锅，我很不理解。狗的一生，都是为了自己的主人，难道就只是因为它老了，不中用了，就否定它存在的价值。这是不可以的!人们还将刚出生的小狗崽扔到湖里、垃圾桶里，将它们随意丢弃，这也是不行的。每个人都有存在的意义和价值，即使是人，也没有资格剥夺它们的生命。

我曾经亲眼目睹了猫被车撞飞后的惨状。那扭曲的脸诉说着它的痛苦。它的鲜血、内脏被撞离体外。尽管雨水冲刷掉血的痕迹，但每当我走到那儿时，脑海就自动地跳出了那一幕，想起那只被撞得面目全非的猫，想起它死前不甘的眼神……

从那时起，我就在心里默默发誓，要尽自己的努力，来保护小动物，至少，也不会让它们无辜枉死。

我想，在将来，我会成立一个“幸福之家”，这里会专门收养流浪小动物，如果好心人愿意收养，我也会赠送给他。这样，那些流浪猫儿、流浪狗儿就有了一个温暖的家。我也会为那些珍贵的濒临灭绝的动物捐款，让它们不至于完全灭绝。

或许，这样的我很傻、很傻，但我愿意做那个傻傻的为在别人眼里微不足道的小动物担心的人。

如果你也像我一样“傻”，那让我们坚定不移地“傻”下去。因为它们都是可爱的。

A triple bacon cheeseburger seems like a heart attack on a plate.

三层奶酪咸肉汉堡感觉吃完很容易让人突发心脏病。

So how can polar bears thrive on their version, seal blubber?

那么,北极熊是如何处理这些高热量食物的呢?

Turns out theyve stocked up on genes that let them clear fats from their blood.

结果显示它们储存在遗传基因里的信息使得它们能够清除血脂。

Thats according to a study in the journal Cell.

这是根据《细胞》杂志上的一篇研究得出的结论。

Polar bears are well adapted to life on the sea ice.

北极熊非常适应在浮冰上的生活。

Up to half their body weights fat, which gives them extra insulation and buoyancy, and provides them with a ready source of energy.

几乎占它们身重一半的脂肪足以使它们保暖并且维持体力，提供给它们一种易转化的能量。

But how can an animal so fat also be so fit?

但一种动物怎么能又胖又健康?

Researchers compared the genomes of polar bears with those of brown bears, and found that polar bears have accumulated genetic changes that boost their heart health and fat metabolism.

研究人员们通过比较北极熊和棕熊的基因，发现北极熊的基因组中积累了不少有利于心脏健康和脂肪代谢的遗传突变。

One gene in particular, called ApoB, helps move cholesterol out of the blood—where it causes problems in humans—and into cells.

特别是编码为载脂蛋白B的基因有助于清除血液中对人类有害的胆固醇转变成细胞代谢。

These genomic changes happened quickly, evolutionarily speaking.

这些遗传变化从进化的角度来讲发生的十分快。

Polar bears and brown bears diverged from a common ancestor less than half a million years ago.

北极熊和棕熊都来自于同一个祖先，它们是在大约50万年前左右开始向不同分支进化。

But if that seems super speedy, the ability to digest lactose didnt spread through human populations until we domesticated cows, just 10,000 years ago.

但是如果这种变化看上去十分快速的话，消化乳糖的酶逐渐进化到人类各个种群中也还是发生在大概1万年前我们可以驯化乳牛之后。

A moooving testament to the power of natural selection.

这是自然选择力量的证明。

Perhaps, everyones heart has their own favorite animals, small to cats, dogs, big to elephants, pandas, giraffes, but, I like animals or insects, small to not see dont see, it is the most easily neglected but a large number of ants.

The ant is a kind of like social insects, dont look at it, but it has a "strong man" title. An ant can lift 50 times more than their weight. 2 times people if can move up the weight of everything is wonderful. People who want to really dust and ants than strength.

Previously, I have heard, the ants are very united, I also saw, in the ant mouth, many ants against a live common caterpillar, thought, and the mere survival needs, hunting together, a lot of animals wolves hunt, hyenas are so common, no surprise. So many ants have thinking every day together, cant afford to infighting just strange!

Later, I saw an article, let I to small awestruck by ants. This article writes: a group of ants meet fire, they didnt panic, immediately transform into a group of formations, these can keep the queens, young ants race survival ant package in the middle, rapid rolling a ball of fire, break through in the direction of the river, outer ant ant regiment repeatedly heard burned after the burst of noise, but not to reduce the ant regiment. Obviously, this outer "ant kingdom hero" by the burning to death also dont loose fraction, courage all crack dont give up their jobs. And in a short while, ant group rushed into the river, as to the other side of the scroll, the river rose a thin layer of smoke... Any creature that has a survival instinct, small ants can in a survival situation, continue to race, choose to sacrifice myself, what a respectable!

Compared with the unity of ants, we should be ashamed of yourself. Sometimes because of the little things, and her classmates went red, shouldnt have. Originally in the world, noble and great really has nothing to do with size, strength, what really matters is strong in spirit, if we have ants so closely united, dedicated spirit, what we cant finish?

也许，每个人的心中都有自己最喜爱的动物，小到小猫、小狗，大到大象、熊猫、长颈鹿，可是，我喜欢的动物或者说是昆虫吧，小到不仔细看根本看不到，它就是最易被人忽视的却又数量庞大的蚂蚁。

蚂蚁是一种喜欢群居的昆虫，别看它微不足道，但它却拥有“大力士”的称号。一只蚂蚁能搬起超过自己体重50倍的物体。人如果能搬起自己体重2倍的东西都很了不起了。人要和蚂蚁比力气可真是望尘莫及。

以前，我曾听别人说过，蚂蚁们十分团结，我也亲眼见过，在蚂蚁洞口，众多蚂蚁共同对付一只活毛毛虫，心想，那只不过是生存需要，共同猎食罢了，好多动物像狼、鬣狗都是这样共同捕食，不足为奇。这么多有思维的蚂蚁天天在一起，不起内讧才怪呢!

后来，看到了一篇文章，让我对小小蚂蚁肃然起敬。这篇文章写道：一群蚂蚁遇到火灾，他们没有惊慌失措，立刻变换队形扭成一团，将蚁后、幼蚁这些可以维持种族生存的蚂蚁包在中间，迅速滚过火球，向河岸方向突围，蚁团不断发出外层蚂蚁被烧焦后爆裂的声响，但是蚁团却不见缩小。显然，这外层被灼焦的“蚁国英雄”们至死也不松动分毫，肝胆俱裂也不放弃自己的岗位。一会儿，蚁团冲进了河流里，随着向对岸的滚动，河面上升腾起一层薄薄的烟雾……但凡生物，都有求生本能，小小蚂蚁却能在生死关头，为了种族延续，选择牺牲自己，多么可敬啊!

和蚂蚁的团结比起来，我们应该感到惭愧。有时因为一点小事，和班里的同学就闹得面红耳赤，真不应该。原来这个世界上，崇高与伟大真的与个头、力量没有关系，真正重要的是精神上的强大，如果，我们具备蚂蚁这样紧密团结，勇于奉献的精神，还有什么事情我们不能完成呢?

My favorite little animal bunny, it has a white fur, the play is very cute. Her two eyes are red, the play is like a pair of red gems. Sparkling. Every morning the little white rabbit to eat a carrot, two pieces of leaves, it is full.
