关于保护动物高中英语作文1：Animals Need Protecting

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 plant on the danger list. Slowly, the number of some animals in danger is growing.

关于保护动物高中英语作文2：Protect animals

I am a student from Xinhua High School in Chongqing，China. Informed that you have a vacancy for a student to serve as the spokesman for animals, I cannot resist my inner excitement,hoping to seize the opportunity to do something for animals .

In my mind，nothing can delight me so much as caring for animals. Wherever I go and whatever I do, I usually keep in mind that animals are angels from the heaven, which bring us endless comfort and pleasure. I have been a panda lover since my childhood. Panda is so lovely that brings fun to people and they are regarded as the treasure of our country. Unfortunately，such a rare species is now faced with the danger of being extinct。What I am eager to do is to raise people’s awareness of animal protection and appeal to more people to care for our earth companies.

关于保护动物高中英语作文3：How tu protect animals

It is known to everyone that the unrestrained slaughter of wild animals has diminished the number of some endangered species. More and more species are being driven to extinction every year. It is terrible to think that magnificent animals are being sacrificed to human vanity

There are already laws enacted to prevent the importation of rare animals and the products made from their flesh, skin and bones.

These laws must be strictly enforced. Violators of these laws must be severely punished .Moreover, the public must be informed about the natural treasures we stand to lose .If we don’t take immediate action, we will be depriving future generations of our most precious heritage.

In Taiwan, because most people do not understand the importance of wildlife, the wildlife is in a poor situation. We Chinese are fond of eating anything delicious, so there are many animals killed by hunters. People enjoy eating tigers, bears, birds, and lions, so there are fewer and fewer birds flying in the sky and fewer and fewer bears running here and there in the forest. Instead, we often see them for sale at the market. How poor they are! And how cruel we are!

In my opinion, we should try every possible way to preserve wildlife. First, no one is allowed to hurt any wild animal. Second, the authorities concerned should punish those who kill any wild animal. Third, we should pay more attention to those endangered species to protect them from being eaten. If we can do so, nature must become very beautiful.

我几乎没有养过什么小动物，比如鸡、鸭、猫、羊、猪……都只有在奶奶家见过，可我最喜欢的小动物要数刚刚出生的小羊羔儿。

今年过年，我们回定西老家，正巧奶奶家的母羊在生小羊羔儿，羊妈妈经过一番痛苦的挣扎之后，终于生出了一只粘乎乎的小羊羔儿。羊妈妈用舌头舔舔它的眼睛，它缓缓地睁开了。羊妈妈又疼爱的舔着小羊羔儿的身体，奇怪，小羊羔儿颤颤巍巍站了起来，吻着妈妈的身体，在她的周围打转，最后，双膝跪地找见了妈妈的乳房，吃了起来，哦!可爱极了，哦!这难道就是妈妈常说的“羊跪乳”吗?

它那么幼小，那么可爱，那么懂事，我说:“爸爸，我要抱一下它，可以吗?”爸爸抱起了小羊羔儿，就在给我的时候，羊妈妈大声叫了起来，“咩咩”，小羊羔儿也叫了起来“咩咩”，那情景就像是在怨怒我们抓走了它的孩子，我连忙放开了小羊羔儿，小羊羔儿又蹦又跳地跑到了羊妈妈的身边。羊妈妈又舔起了小羊羔儿。

我喜欢小羊羔儿，也喜欢充满爱心的羊妈妈。

我养了一只仓鼠，因为它浑身雪白，白得没有一根杂毛，所以我叫它小白。

它的小嘴尖尖的，眼睛乌黑乌黑的，像一对闪闪发光的黑宝石。小鼻子像一个小圆点，显得很小。它的耳朵最可爱，毛茸茸的，像两个小小的绒球。

它吃东西更有趣，当我把它最喜欢吃的饼干放入笼子，不知道为什么，我在的时候，它就不吃，有一天，我把自己藏起来，小白见四周没人，终于开始吃东西了。它细吞慢咽，时不时还东张西望，生怕有人看见它。

为什么说小白调皮呢？因为有几次，我把它放出来玩，小白不是跑到床下，就是钻到沙发下，好像在和我们躲猫猫。从那天起，我就很少把它放出来了。

但是，我的小白在一次意外中集我们而去，我非常伤心，每天都在祈祷，希望小白能在天堂过上幸福的生活。

小朋友们，今天，我们又见面了，我要写一篇《我喜欢的小动物》，你们愿意帮助我完成这篇作文吗？如果愿意，就赶快拿起手中的笔，一起来帮助我完成这篇作文吧！

上次，妈妈给我买了两只小鸡，我十分喜欢这两只小鸡。

小鸡浑身长满黄色的羽毛，小嘴尖尖的，两颗圆溜溜的小眼睛闪烁不定，好像天上的星星，两个小爪子细细的，叫声“叽叽”的。

我把它们放在一个大纸箱里，然后我把它们放在楼道旁。

一天放学回家我去给它们喂米，我先抓了一把米，然后伸进纸箱里，它们伸长脖子去啄米，那时候我的手心痒极了。

可不幸的是后来这两只小鸡被小猫吃了，我伤心极了。

我喜欢的小动物数也数不清，有小松鼠、大熊猫、小兔子、小花狗、孔雀、小猫咪……。其中我最喜欢的是小松鼠。

小松鼠的样子非常可爱，它有一双雪亮的眼睛，两只毛茸茸的耳朵，一双很小的小手和一双小巧玲珑的脚。

小松鼠睡起觉来经常地把它的大尾巴盖在身体上，把双手伸起来，有时候它把一只手放在地上，然后又把脑瓜趴在手上，在用尾巴圈起来。

小松鼠很调皮，当我把松果扔到了果皮箱李，它有把松果拿起来，把松果分成了五份，最小的留给自己，别的四块给了四个小松鼠。

小松鼠跑步速度非常的快，我把小松鼠放了出来，和我比赛，我都跑的满头大汗的时候，它还在跑，都跑好几米了，它竟然一点也不累。

小松鼠真让人喜爱呀！

每天，我放学回家的路上，到我们家小区的时候，每次我都会看楼的侧边，都会有一个小洞，我一直在想这些小洞到底是什么？如果不是那天看到，我就不知道。

一天，我正经过那层楼房时，突然，听到上面有一阵“叽叽喳喳”的鸟叫声，“什么？哪里来的鸟叫声？”我正奇怪的望着天空时，无意中扫到了那个墙壁上的那小洞，这时，一直麻雀从天而降，落在了那个小洞旁边的电线上，小脑袋机灵的转来转去，过了一会，那只可爱的小麻雀居然钻进了墙壁上的小洞！“什么！”我不禁叫出了声来，“那只麻雀干什么？它为什么钻进那个洞里？难道里面是麻雀窝吗？麻雀窝不应该是树上吗？”一大堆问题冒了出来，可是身边又没有别人，心里的疑问只能由我来一一解开了。

于是，我捡起地上的小树枝朝洞旁边的墙上扔去，“啪”当树枝砸到墙壁时，“叽叽喳喳”，这时，从小洞里传来了一阵麻雀的叫声，可就是没有一只麻雀出来，我实在等不下去就走了。

过了几天，我又来到那栋楼的侧边的墙壁旁边，我仰望着那个洞，这时，我突然看到了一只很小很小的麻雀从那个洞里钻了出来，“叽叽叽”“叽叽叽”地在旁边的电线上唱歌，那声音真好听。

我朝那只小麻雀望去，看到它扑了扑翅膀，但是，却飞不起来，它的嘴角嫩黄，头上长着绒毛，分明是刚出生的。

小麻雀的肚子是白色的，圆圆的下垂很可爱。

最后我还是恋恋不舍的离开了。

Panda—the National Treasure

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.

In our common home - the earth, living a lot of animals, what kind of animals do you like? Anyway, my favorite animal is our most loyal friend - dog.

I most love the dog is my neighbors dog Beijing Pakistan round and Collie handsome. Every day they play together, is a good friend of clubbing lingers, I also love them, they saw me and wagged his tail and ran towards me.

Handsome, big body, about more than 60 centimeters long. Two legs standing, completely to my shoulder, his eyes, nose, mouth, ears are mostly round, I love watching him running figure -- like curly flying, a horse. I often run with the round, handsome and handsome, every time is handsome, first, round second, I third. It is no exaggeration to say that the speed of the lion is no less than the speed of a thoroughbred horse. The general dog ran up, will be issued a "clicking" sound, but handsome running in a low voice, not carefully hear. The handsome man also looked handsome when he ran: curly hair flying and his body arched. If you want to use a word to describe Shuai Shuai, that is: shuai. If one word is used, it is impeccable.

Relative to Shuai Shuai, the round shape is a lot smaller, the body length is only about thirty centimeters, smaller than the handsome about half. His name comes from his eyes, which is so round. Like a shiny black stone. And his legs are round, too. The round name comes in this way. And his leg is very short, so even if he cast the foot run, couldnt run fast, but I still love his simple cute.

Thats what I like about animals. What do you like?

I have a dog,his name is Joy.He is very lovely like other dogs.When he feels happy,he always wags his tail.When he wants to eat food,he often follows me until I give him something to eat.I really like him.When I feel sad,he often stays with me as if he knew why I was sad.Thanks to him,he puts me out of my misery,so that I can live happily.He let me know dogs are humans best friends.

我们要保护小动物，特别是小鸡这类弱小的动物，因为小鸡早晨可以叫我们起床，可以生一个又一个圆圆的的鸡蛋，还可以提供鸡肉给我们吃。

We need to protect the small animal, especially this kind of small animal chicken, because chicken morning to wake us up, can have a round egg, can also provide for us to eat chicken.

有一次，我和妈妈上菜市场，听见一位老奶奶在喊：“卖鸡了，今天的鸡又肥又嫩!”妈妈说：“今天，我们买一只鸡回家，炖汤喝。”我说：“好吧。”可又想了想：如果我们吃了鸡，那么就吃不到鸡蛋了，就对妈妈说：“不行，吃了鸡就没有鸡蛋吃了。”“傻孩子，你瞎操什么心啊!”妈妈不由分说地把我拉到卖鸡的那边。卖鸡的老奶奶正在杀鸡，只见她拔下鸡脖子上的毛，拿刀用力地在鸡脖子上划了几下。血喷向了四周，鸡挣扎了几下就死了。“太残忍了，我不要吃鸡!”我向妈妈大声的抗议。“好吧，不买了，我们就去买点蔬菜吧。”也许妈妈也觉得残忍，就同意了。

One time, my mother and I heard the food market, an old woman shouted: "chicken, chicken fat and tender today!" Mother said: "today, we bought a chicken soup to drink at home." I said: "OK." But think again: if we eat chicken, so cant eat the egg, the mother said: "no, not eat chicken egg to eat." "Silly boy, what do you care ah!" Mother allowing no explanation to put me into the chicken. The old woman was a chicken, she pulled out the hair on the neck, a knife in the neck with a few strokes under. Blood sprayed around chicken, struggled and died. "So cruel, I dont eat chicken!" I asked my mother loudly protested. "Well, do not buy, we went to buy some vegetables." Maybe mom was cruel, also agreed.

假如我们的生活中没有了动物，世界就会变得很孤独。我们要保护动物，从自身做起：少吃肉类食品，少穿皮衣毛衣;看见别人欺负动物，要勇敢地站出来劝说他们。

If we live without the animal, the world will become very lonely. We must protect the animal, start from their own: eat less meat, less wear fur sweaters; see others bully animal, we should stand up to persuade them.

保护动物，人人有责!

Animal protection, everyones responsibility!

在我的记忆中，我曾经养过鸡、鸭子、鱼、鹦鹉、乌龟和鸭子。在这些小动物中，我最喜欢的就是鸭子，因为它和我有一段很长的故事呢！

一个星期六的早上，妈妈带我去玉渊潭公园玩。在公园的广场里，爷爷奶奶们在跳老年舞蹈，小孩子们在追跑戏耍，还有卖玩具的，真是热闹。

远远地望去，我看到一个老奶奶在卖鸭子，我飞快地跑了过去，并在老奶奶旁边蹲下来，看着小鸭子们的一举一动。妈妈慢慢地走了过来，看到我全神贯注地盯着箱子里的鸭子们，妈妈知道我心里一定很喜欢，于是便说：“大妈，小鸭子多少钱一只啊？”奶奶说：“两元一只。”于是拿出钱包把两元钱交给了奶奶。我立马开始精心地挑选起来，终于找了一只毛茸茸的小鸭子，我用双手小心翼翼地把它放到了塑料袋子里。

小鸭子在我的精心饲养和照料下渐渐地长大了。可是有一天妈妈对我说：“咱家不能再养它了，因为小鸭子已经长得太大了，没地方放了，就把它放生吧。”我坚决不同意，跟妈妈哭闹着，因为我怕它冻死、饿死。妈妈见我这么说，就放弃了放生的念头，跟我说：“孩子，这样吧，我同事家有一个院子，小鸭子在院子里生活会更加快乐。”我考虑了一下，尽管我不舍得小鸭子，但是为了它能更加快乐地成长，只能这样了。第二天下午，我与妈妈恋恋不舍地把小鸭子送到了妈妈同事的家里。看着小鸭子在大院子里快乐地拍着翅膀，我又高兴又难过。

小鸭子，我那可爱的小鸭子，虽然现在它不在我身边了，但我还经常回忆起与它在一起的美好时光。

Why should we protect wildlife animals?

Do you know of any endangered animals?Why are they in danger?

I think there are many endangered animals in the world,such as tigers and pandas.When farmers cut down trees,tigers can no longer hide and hunt.Many tigers are killed by people who want to sell their fur for money.And there are few places where pandas can live.We are not alone in the world.We human beings could not live without all the plants and animals around us.So protecting wildlife animals are very important.We must take measures to keep plants from being destroyed and stop animals from being killed.If each of us can plant a tree and build a birdhouse,the world will be more beautiful.It is very easy but useful.

[关于保护动物的小学生英语作文

一身洁白又柔软的毛，小小的鼻子上衬着一颗水灵灵的眼睛。叫声又娇小又动听，走起路来静悄悄的。还不时摇晃那一条尾巴，既俊俏又可爱。它，是我最喜欢的动物——猫。

我家养了一只可爱的小白猫，它很温顺，却又很顽皮。有一次，妈妈买了一个花瓶，放在桌子上。小猫咪盯着它看了半天，还不时发出“喵喵喵”的叫声，突然它一个箭步冲了过去，在花瓶边上，似乎在细细打量着它。它不时凑得更近些，嗅嗅这花瓶。还不时摇动着它的尾巴。突然，只听见一声巨响，花瓶碎了，是小猫不小心打碎的，小猫又惊又怕，飞快跑进床底下，还发出“喵喵喵”的叫声。

小猫虽然很顽皮，但也很可爱。每当我们围着桌子吃饭时，它会独自呆在一旁，默默地享受着它的“大餐”，等它吃完了，便和我们一起去散步。它似乎觉得很无聊，这样的神态却让我觉得很有趣。

都说猫和老鼠是天敌，可我不这么觉得。我家的猫不仅不捉老鼠，似乎还有一点儿怕老鼠！晚上，它总在黑漆漆的屋子里走来走去，似乎没有一点儿睡意。当老鼠出没的时候，它突然跑回属于自己的那一块领地，闭上水汪汪的眼睛，一会儿就睡着了。

每天，我都会抽空陪它玩。有事我扔一个球过去，它会把球捡回来。在于它玩耍的过程中，我十分开心，我感到了人与动物之间的那份情谊，不知道小猫怎么想的，我猜它一定非常开心吧！

看，这就是我最喜欢的动物——猫。怎么样？可爱吧！

“汪汪汪”你们已经知道这是什么动物了吧？对，没错，是狗，是人类最忠实的朋友。我家。就有那么一条小狗。

小狗身上的毛有黑有白，是一条花斑狗，于是我叫它小花。小花的鼻子又湿又黑，像抹了一层油，十分灵敏，一百米以内都能味道气味。一条短短的尾巴，挂在屁股上面，遇见主人就会欢快的甩个不停，还伸出长舌头不停地舔着主人。

小花吃东西时十分警惕，他不会直接吃。它先闻一下，再用爪子碰一下，又闻一下，直到觉得没有危险了，才狼吞虎咽地吃起来。还高兴得边吃边摇尾巴。

小花最喜欢的食物是火腿肠和牛奶。一次，我从厨房拿出一根火腿肠，正想叫小花来吃，可小花却早已经闻到了火腿肠的味道。马上跑过来，于是，我将火腿肠剪开，放在小花面前，小花马上吃起来，吃得津津有味。火腿肠渐渐由长变短，不一会儿就“全军覆没”了。小花马上抖一抖脸，将脸上的东西抖到地上。又用那双黑油油的眼睛盯着我，好像感觉缺少了点什么，直到我把一瓶牛奶放在她面前，他才心满意足地喝起来。喝完牛奶，小花舔了舔舌头，开开心心地找他的小伙伴玩去了。

小花十分淘气，天天都要出去玩，于是我每天都会带它出去玩。一路上，小花总是一会儿躲在草丛里，一会儿跑出来，好像在和我玩捉迷藏。到了公园，小花马上去荡秋千，小花一直摇秋千，有时摇得太快，把自己给甩了出去了，真是太好笑了。

小花睡觉的时候十分有趣。小花刚进窝根本睡不了，总是要闹腾一阵子，一直翻滚，有时甚至撞到了砖头也还再翻，不一会儿就呼呼大睡起来了。

小花真可爱，小朋友们，你们也有自己喜欢的动物吧！来介绍一下。

[我最喜欢的动物小狗4年级作文

Every year on October 4th is the World Animal Day. It is proposed by the Italian monk St Francis in 12th century. He lives in the forests of Assisi Island for the long time, building a good relationship with the animals. So he asks people to express thanks to the animals on October 4th. He sets a good example for our human beings about how to deal with the relationship with animals. In order to memorize him and what he does, we make October, 4th to be World Animal Day. Nowadays, people from all over the world will hold various activities to celebrate on that day. The aim of this festival is to remind people to care for all animals and build a harmonious relationship with them.

每年的十月四日是世界动物日。它是由意大利修道士圣弗兰西斯在十二世纪提出的。他长期生活在阿西西岛上的森林中，与动物建立了良好的关系。所以他要求村民们在10月4日这天向动物表示感谢。他为如何正确处理与动物的关系树立了一个很好的榜样。后人为了纪念他和他所做的，我们把十月四号定为世界动物日。现在，在那一天来自世界各地的人会用各种活动来庆祝这一节日。这一节日的目的在于提醒人们关爱所有的动物，与他们建立和谐的关系。

我最喜欢的是小白兔，一身雪白的毛，一对长长的耳朵，凑成了活泼机灵的小白兔。

我们家养了一只小白兔，它有一个红眼珠、三半嘴、漂亮极了！小白兔身上长着雪白的毛，摸上去软绵绵的。那双红的眼睛好像它一直很疲劳似的，布满了血丝，怪叫人疼爱的小白兔两只肥肥的耳朵耷拉拉着，嘴上的胡须轻轻地抖动着，像一个老人民细细地嚼着东西。

白兔来了个多月了，她已经成了我家一员，奶奶问我家中有哪些人，我总是扳着小手说：“奶奶、爷爷、爸爸、妈妈，我还有小白兔一共六个。奶奶听了哈哈大笑。的确小白兔是我的伙伴，在长期的饲养中，我发现它有很多有趣的地方。”

小白兔很温驯，但见生人很怕羞。如果你去摸摸它，就好像有人欺侮它似的，便没命逃，可是如果主人走到她面前它不但不逃，反而会支起前腿两只眼睛一动不动的盯着你好像在听候主人的交代。

小白兔的看家本领就是跑，童话书上说：“乌龟和兔赛跑，只要有人欺侮它，它就跑，不那强有力的四肢，是它生命的保护器官”

小白兔是我小时候的朋友，它给我增添了童年的快乐，并且在我幼小的心灵中埋下了一颗热爱自然的种子。给我增添了童年的快乐，并且在我幼小的心灵中埋下了一颗热爱自然的种子。

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。
