人类与动物英语作文(精彩20篇)

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.

What animal do you like best ?Is it elephant ?Or tiger ?But my favorite animal is monkey . Because they have the yellow skin,a big mouth ,a small nose,and two big eyes .They climb trees quickly ,and they can pick bananas or apples .I think they are very lovely and interesting!

So I hope you to like them ,too.

你最喜欢什么动物?大象吗?还是老虎?但我最喜欢的动物是猴子。因为他们有黄色的皮肤，一个大嘴巴，一个小鼻子，两只大眼睛，他们很快地爬上树，他们可以摘香蕉或苹果，我认为他们非常可爱和有趣!

所以我希望你也喜欢他们。

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。

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。

The global polar bear population could decline by more than 30 percent in as little as 35 years. Thats according to a new study in The Royal Societys Biology Letters.

全球北极熊数量在35年内可能下降超过百分之30。这是根据英国皇家学会生物学快报的一项新研究。

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

研究人员观察气候变化对北极海的影响，并计算出预计种群下降的可能性为百分之71。

Thats because polar bears stand on Arctic Sea ice when hunting for seals. According to NASA, even the thickest ice in the Arctic Ocean has "either thinned or melted away."

这是因为北极熊捕猎海豹时站在北极海的冰上。美国国家航空航天局表示，甚至北冰洋最厚的冰要么变薄或要么融化了。

And just this week, scientists reported sea ice levels in the area were at a record low for this time of year.

就在本周科学家报告称，该地区的海冰水平创下一年中这个时候的历史新低。

This all adds up to not great news for polar bears. With an estimated population of 26,000, the bears are already listed as a vulnerable species by the International Union for the Conservation of Nature.

这对北极熊不是什么好的消息。现估计有26,000头北极熊，已被国际自然保护联合会列为易危物种。

human activity has damaged natural environment and almostexaustednatural resources. modern industry needs more and moreresources,including minerals, fuels and water. so we confront ofthe seriousproblems such as the lack of fuels and water.ecological balance isdamaged because factories occupy many placeswhere animals andplants live. more and more buildings areconstructed and forestsbecome less and less. if we cannotrecognize these problems andsolve them soon, we would finally losethe environment suitable forour living.an other serious problem is the green-house effect.humanactivity decreases forests and increases the usage of fuels sothatthe gas of carbon dioxide is output more and more and there arenotenough plants to absorb it. the green-house effect is moreobviousand more sensible these years. due to the effect, icebergsin thesouth polar and north polar melt and the sea level becomeshigherthan before. i am worried about the cities nearby the sea andhopescientists find an effective method to eliminate thegreen-houseeffect.

Heard the story of the tree a tiger? People use glue to stick to a tree tiger first, and then with the help of their kind nature, attract more tiger fur expensive tree. The overlord of the world, mankind is a great shame!

Since the childhood, I grew up with dogs, because dogs are mans most loyal friend. When I and my grandma often see grandma unprovoked kicked the dog, whenever at this time, I will be to grandma Shouting: "how can you kick the dog grandma?" But how can you listen to grandma? Look at the pathetic little dog, I cant help but nose a acid: because we are human in the earth is to get the ability? Does the dog have dignity? For those self-righteous humans, I have nothing to say! Animals are mans most loyal friend!

Why can only to the snake bite? Know why cats catch people? Not because this is the essence of them, but because they are afraid of human, afraid of the cruel devil! To stop bullying, let us together to protect animals!

听说过树虎的故事吗?人们用胶水先粘住一只树虎，然后借助他们善良的本质，引来更多皮毛昂贵的树虎。这对世界的霸主----人类可谓是极大的耻辱!

从小，我就是和小狗一起长大的，因为狗是人类最忠诚的朋友。我和奶奶在一起时常常看见奶奶无缘无故的踢小狗，每当这时，我都会对奶奶大吼大叫：“奶奶你怎么能踢小狗呢?”可奶奶又怎么能听得进去呢?看着这只可怜兮兮的小狗，我不禁鼻子一酸：因为我们是人类就能在地球是为所欲为了吗?难道小狗就没有尊严吗?对那些自以为是的人类，我无可奉告!动物是人类最忠诚的朋友啊!

只能够到蛇为什么会咬人吗?知道猫为什么会抓人吗?不是因为这是他们的本质，而是因为它们怕人类，怕那些残忍的恶魔!不要再欺负弱小了，让我们一起保护动物吧!

——读《被宠坏的狗熊》有感

在文章《被宠坏的狗熊》中主要讲了：人与动物美好相处，人如果不伤害动物，动物也不会伤害人，如果人与动物相处久了也会成为要好的朋友。

作家玛罗吉安诺娃的作品中，最让我感动的是《名字叫“土匪”的狒狒》。

《名字叫“土匪”的狒狒》主要说：我与一个狒狒成为了好朋友，并取名为“土匪”可是当“我们”玩的正开心的时候，却传来噩耗︰我要搬家了。可能再也见不到“土匪”了。

六年后……

我回来了，当我又一次去看“土匪”时，它已经很老了，双目失明，我央求女饲养员让我看看“土匪”，“土匪”听到我的声音，喜出望外，原来“土匪”还认识我。

作家格斯聂吉廖夫的作品中，最有趣的是《小怪物》。

这篇文章主要写了我们的船向朝阿纳德尔湾驶去，时间已是晚上。船走了许久我发现船后有一条抹香鲸，我问船长︰“它为什么跟在我们后面。”船长说它把我们当大鲸了，它还很小，看来是掉队找不到妈妈了。真有趣！

作家斯萨哈尔诺夫的作品中，我最喜欢《白鲸妈妈》。

它主要写了一年夏天，我到卡宁半岛去。一天，我在浅水区发现一头白鲸。格利莎想把它打死，因为打白鲸是它的工作，忽然格利莎站住了，因为他看到一只小白鲸在浑浊的海水里找不到妈妈了，在等死。白鲸妈妈焦急不安地乱转。

一个浪头打过，小白鲸不再移动了——它搁浅了。但是它没有死

白鲸第二次在小汽艇旁浮出水面，水里露出一个凸起的脑门儿，后来它游进了浅水区，我们为了救它，只好用绳子的一头系在船上，第二条绳子栓在鳍上。把小白鲸拖到了深水区，格利莎割断了绳子，小白鲸自由了。

过了一会儿，就在我们旁边，一个巨大的白色物体浮上了水面——白鲸妈妈向儿子游去。小白鲸开始往下沉，后来它们游走了。

一年以后，有关方面下令禁止猎鲸。我真高兴。

一天，我去动物园玩，我看到一只可爱的猴子，我想和它玩，想不到它看到我就跑，这，我是可以理解的，因为猴子看到生人一定会跑。我从口袋里拿出几颗糖，递给小猴吃，它拿到糖高兴地上蹿下跳，然后，又回到我的旁边，向我点点头，好像说︰“谢谢你！”

看，只要人类与动物和谐相处，人类就可以和动物们成为好朋友。

One day，my mother bought two little rabbits for me.I’m very happy.

From that on，the two little rabbits became my good friends. They have two little ears， red eyes，with white and fat boby. They’re marvellous.

I love my little rabbits，and they love me. They are my good friends forever.

参考译文：

一天，我妈母亲给我买了两只小兔子。我特别的开心。

从那天起，两只小兔子成为了我的好朋友。它们有两只小小的耳朵，红红的眼睛和一个又白又胖的身子。它们很了不起的。

每日，它们互相玩的很开心。一天，我找不到它们了，我问我的母亲，“它们哪去了？”我母亲告诉我她不清楚。最后，我在草坪发现它们。它们很脏。我很生气，但当我看到它们那可爱的脸，我又开心起来了。

兔子是一种可爱的动物，很讨人喜欢。他四肢灵活，行动敏捷。玲珑的小面孔上镶嵌着一对闪闪发光的红宝石似的圆眼睛。他长者一对长长的大耳朵，身上的毛非常光滑，一条短短的尾巴显得格外可爱。

兔子真有趣。他吃东西的时候非常小心，觉得没有任何危险，感觉安全了才会出来吃东西。

兔子很讲卫生。他今天在这里上厕所，明天还会来这里上厕所。

兔子喜欢吃青菜、萝卜……。兔子一般不喝水，因为菜里面含有许多水分，吃了菜就等于喝上水了。

啊!小兔子真可爱呀。

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?

清晨，我在家又没人陪我玩，妈妈去上班了。我就去朋友家玩，可朋友又不在家，我就在他家门外看见了一棵大树，我就往上看，上面有一只啄木鸟在给大树治病。刚好，地上有一个弹弓，我就拿起弹弓，瞄准啄木鸟，正要发射的时候，我的朋友小红回来了，他看见了，就连忙跑过来，说：“小明，快放下，”小明奇怪地问：“为什么啊，”小红说：“因为啄木鸟正在帮我家的大树治病呢，还有，老师也说过我们要保护动物的呀，”小明说：“小红我知错了，我一定会改的，”小明回家了，我就我在小红家做的事告诉了妈妈，妈妈就说：“小明你真是知错能改的乖孩子。

Early in the morning, I at home and no one to play with me, my mother go to work. I went to a friends house to play, can be friends and not at home, I saw a tree outside his door, I look up, there is a woodpecker to cure in the tree. Just, a catapult on the ground, I picked up a slingshot, aim at the woodpecker, when I was about to launch, my friend Xiao Hong came back, he saw, hurriedly run to come over, said: "Xiao Ming, fast down," Xiaoming asks strangely: "why," Alice said: "cure because the woodpecker was helping my family tree, and, the teacher also said that we should protect the animal ah," Xiao Ming said: "red I was wrong, Ill change," Xiao Ming came home, I told my mother I in the red house do, mother said: "Xiao Ming you are really rectifies the lovely children.

我们可一定要向知错能改的好孩子，小明学习呀。

We must ask rectifies the good child, Xiao Ming studying.

This fish earned its name by utilizing evasion as a way to escape its predators. It bodily leaps from the ocean, reaching a speed of about 35 miles per hour and a recorded gliding time of up to thirty seconds. This can take them as far as 200 meters from their point of exit from the water, which may be far enough to escape pursuit or confuse predators. Fishermen favor these types of fish, but due to their sheer numbers in the wild, none of the 40 different species of flying fish are listed as endangered. While they can be found foraging seasonally along the outskirts of warm water reef complexes, flying fish are primarily pelagic, and favor tropical or subtropical open waters around the equator.

飞鱼得名于它独特的避难方式。遇到捕食者时，飞鱼会采用一种独特的逃跑方式：它会纵身一跃，跳出海面。此时它的速度可达到每小时35英里，在空中滑翔长达30秒。这一跃能使它们飞行200米，足以使它们全身而退或者迷惑捕食者。渔民们很是钟爱这种鱼，野生飞鱼数量众多，所以40种飞鱼中没有一种濒临灭绝。人们发现飞鱼有时会季节性的在温水区近郊地带的杂礁灰岩附近觅食，不过它们属浮游类鱼类，喜欢在赤道附近的热带，亚热带地区的公海活动。

Subsisting mainly on a diet of plankton and small marine life, flying fish are schooling fish that hunt primarily at night. While some sources may find this counter-intuitive, given the ease with which the fish are drawn to light sources, this actually makes perfect sense. Many of the plankton and marine resources the fish favor are slightly luminescent, especially by moonlight, making them easily seen in the darkness. This also provides cover, given the coloration of the fish—blue or grey on top, silvery white on the bottom—so that they are not easily seen from above or below as they feed on the clouds of marine flora. Flying fish generally mate during the autumn or spring, when currents are at their weakest. Females will deposit their eggs on the surface, attached to flotsam, and males will fertilize the eggs. Schools at this time can number in the millions, and constitute a major resource for species that feed on the fish. Because they only tend to live about five years in the wild, their flesh is prized for its purity—free of the heavy metals often found in longer-lived species.

飞鱼主要以浮游生物和小型海洋生物为食，主要在夜间以集群的方式进行捕食。有些人会觉得下面这个说法有悖常理，因为鱼类易被光源吸引，这么说也不无道理。许多浮游生物和鱼类自身都会发出微弱的冷光，尤其是在月光照射下，更是清晰可见。但这同时也为鱼类提供了一层防护，让它们有了保护色：一般在上部会呈现蓝色或灰色，下部呈现银白色。凭借这些保护色，当飞鱼在海底植物中进食时就很难发现它们。飞鱼通常会在春秋时节进行交配，因为这个时期洋流的活动最为和缓。雌性飞鱼会将卵产在海面上，让其依附在漂浮物上，雄性飞鱼再让鱼卵受精。此时在飞鱼的集群中，会有数以百万的成员。而这也为以鱼类为生的动物们提供了主要的食物来源。由于野生飞鱼只有5年的寿命，它们不会像长寿的鱼类一样体内留有大量重金属物质，因此飞鱼肉被人们视为珍品。

2014年中秋节，我和爸爸妈妈开车回农村老家去看望奶奶。上午八点多，我们下了高速走在回老家的山路上，从车窗向外看去，一片片绿色的农田，一排排整齐的白杨，一群群吃草的牛羊，一朵朵盛开的山花，令人心情格外舒畅。路边的小溪在轻轻吟唱着山歌，树上的小鸟在互相追逐嬉戏，果园里果实累累飘出诱人的香味。如此幽美的自然景象，我都要陶醉了。

突然，一只野兔从路边草丛里奔跑出来，差点撞在车头上。又过了一会儿，几只山鸡从小溪边的树林中飞起高声叫着落在对面半山腰。这种与大自然亲密接触的感觉实在是太美妙了！我们这些常年生活在城市里的孩子平时是没有机会感受如此美好的田园风景的。

当我们快要走到奶奶家村边的时候，又有一只大灰兔子从农田里跑出来。它发现我们的车后，并没有像我想象的那样受到惊吓，而是放心地蹲在路边一动不动地看着我们，好像在说：“欢迎你们回到家！”我感到很奇怪，就问爸爸：“兔子为什么不跑掉呢？”爸爸说：“它知道我们不会伤害它，所以不跑。十多年前可不是这样的，那时，村里家家都有猎枪，好多动物都被打杀得几乎要灭绝了。后来政府收走了猎枪，明确规定不让再杀害动物了，提倡爱护动物，保护环境，建设生态家园。这样一来，各种动物就又慢慢繁殖起来了。在老家的大山里，生活着各种各样的动物，大到野猪、野羊、狐狸、獾子、豹子，小到鹌鹑、山鸡、野兔、黄鼠狼、小松鼠、小刺猬和各种各样的小鸟，真是数也数不清。明年放了暑假我带你上山去好好感受感受。”

听了爸爸的话，我非常激动，也很受教育，想想一路上的所见所闻，看到眼前这风景优美的人与动物友好相处的生态环境，我更加明白了保护自然环境和生态平衡是多么的重要！这让我想起了语文书上讲的：动物是人类的朋友，爱护动物就是爱护人类自己，人和动物都是地球的主人。

My cat really cute! Body hair is white, its a green a blue eyes, when I see a mouse, its eyes will stare, as if in said: "still not quick walk", if the mouse does not walk, it pretends to save in the past, the mouse ran away immediately.

Cats eat fish and meat. When I put the fish in it before, it swoops down in the past, started to bite, riddance soon.

Kitten will watch TV, whenever I turn on the TV, it always sits by my side and I watch TV together. Until I turned off the TV, it jumped off the sofa.

Cats sleep body curled up, if they do not look in the distance, thought it was a mass of white balls!

Teasing the cat, I always take something white to make it, because it is strange to like to go with white thing. I move, it starts to move, until met that thing. Outdoors, even if I get the white thread running, it also follow a white line run, until I was exhausted, put the rope down to grasp it, stop it. Sometimes I hang rope on high, and it is also hard to jump, until it caught the rope.

Of course, it will also make me, when I eat, homework, it always rub to rub on my pants, until rub wrinkled.

I like my lovely cat, I also want to teach it some skills, and make it better!

我家的小猫真的好可爱!身上的毛是白色的，它的眼睛一只绿一只蓝，每当看到老鼠，它的眼睛就会瞪得老大，好像它在说：“还不快走”，如果老鼠还不走，它就假装要扑过去，老鼠马上跑了。

小猫吃鱼和肉。每当把鱼肉放在它面前，它就猛扑过去，开始撕咬起来，不一会儿就消灭光了。

小猫还会看电视，每当我打开电视，它总是坐在我身旁和我一起看电视。直到我关了电视，它才跳下沙发。

猫睡觉时身子蜷成一团，在远处若不细看，还以为是一团白球呢!

逗小猫时，我总是手拿白色的东西逗它，因为它很奇怪地喜欢跟着白色的东西走。我移动一下，它也跟着移动一下，直到碰到那东西为止。在户外，哪怕我拿一根白线不停的跑，它也跟着白线跑，直到我筋疲力尽，把绳子放下让它抓到时，它才停下来。有时我把绳子挂在高处，它也拚命跳，直到抓到那绳子为止。

当然，它也会逗我，在我吃饭、写作业时，它总在我裤子上搓来搓去，直到搓得皱皱巴巴。

我喜欢我家的可爱小猫，我还要教它一些技能，让它更棒!

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.

At present,the endangered animals are increasingly fast.How to protect them become our priority.People are crazy about killing animals for their meat, fur.But it is wrong because that animals are our friends, we should try to protect them,instead of killing them to die out. Pandas are represents of endangered animals, which live in the forest and live on bamboos for food. They only depend on the nature reserves to live. We should stop killing animals, and protect them better

When I was very small, I lived in my hometown. My grandparents raised two

dogs, and I liked them very much. I watched them grow up from the little animals

to the big dogs. Every time when I leaved home for school, they would follow me

for some distance. When I walked a little far away, they would turn home. When I

went home after school, they would wait for me in the door and swayed their

tails. I knew they were welcoming me home. They were like my family members and

I learned that animals are part of our nature. We should protect them. We can

create a harmonious society.

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.

古时候，人们看到鱼儿在水里游，自由自在，就根据鱼的胸、鳍发明了船和桨。人们看到鸟在天上飞，就发明了飞机，实现了人们“飞向蓝天”的愿望。

通过研究鱼的呼吸器官——鳃，人类模仿鱼鳃的结构，用两层硅橡胶薄膜做成了具有鳃的功能的半透明膜，可以作为人在水中呼吸使用的“人工鳃”。人类还根据鳄鱼排盐的机理，制成了高效的“淡化器”，可以用于提取或浓集某些分散状态的元素……

苍蝇的复眼包含4000个可独立成像的单眼，能看清几乎360。范围内的物体。在蝇眼的启示下，人们制成了由1329块小透镜组成的一次可拍1329张高分辨率照片的蝇眼照像机，在军事、医学、航空、航天上被广泛应用。

人类通过研究萤火虫等生物发光，正在进一步造出新型的高效人工冷光源。如果能创造出一种象生物放光的物质一样，涂在室内墙壁上，白天能接受光照，贮存能量，夜晚就自然地发出光亮来，那该是多好啊!

人们又从大乌龟背小乌龟身上得到启示，小乌龟在大乌龟的背上可以朝任何方向，因此，人类又发明了转动型大炮。

动物给了人类许多启示，真是人类的老师!
