保护濒危动物的英语作文八十字左右【20篇】

Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

读书认字、看图赏画、看人物、欣赏美景等都要用到眼睛。 所以我们要保护好自己的眼睛。

Animal Protection

Animal is the friend of mankind, is an important part of the natural ecosystem. It is human precious naturalresources. Protect animals to maintain natural ecological balance has important significance.

But now many animals are facing the danger of extinction.With the development of society, pesticide used and serious pollution, city sewage .The wild animal living area is becoming increasingly narrow. Many of the animal is facing a food crisis currently . Whats more, in order to obtain wild animal of precious materials, humans are killing animals.

In order to maintain ecological balance, we should take some effective measures to protect animals.We should develop pollution standards to reduce emission of toxic substances, prevent the killing of some rare animals strictly. We can also establish a national park as a wild animal protection area. The most important thing is to improve people s knowledge of animal care.

Let us join hands in creating a harmonious coexistence of human and animal beautiful homes!

Do you know what my favorite animal? Is the dog of course. My grandma keep a dog, it has a beautiful black hair, a pair of intense big eyes, four legs as fast like a rocket.

One day, I found more doghouse puppy, oh! Originally was born a bitch, a total of four. The dog is cute and naughty, every day running around in the yard, for a while to run the house, ran upstairs after a while, a moment to hide it, run it after a while, as if with a group of friends hide under, from time to time, the old dog to the dog barked two cry, as if to say: "children, dont go to far, pay attention to safety." Play with the dogs have been tired of a day, a meal, stretch and a yawn, into the arms of mother, dogs quickly into the sweet dream sweet, return in mouth every now and then a rumbling sound, as if to say talk in a dream.

The next morning, the birds singing in the branches, wake up the sleeping dog, a yawn, they stretch, rub the sleepy sleepy eyes, began to a day of happy life.

Look! How happy puppy, it is a happiness.

你知道我最喜欢什么动物吗?当然是小狗。我姥姥家养了一只小狗，它有一身乌黑亮丽的毛，一双炯炯有神的大眼睛，四只腿跑得像火箭一样快。

有一天，我发现狗窝里又多了一些小狗，哦!原来是这只母狗生的，一共四只。这些小狗又可爱又调皮，每天在院子里跑来跑去，一会跑屋里，一会跑楼上，一会躲那，一会跑这，好像跟一群小朋友躲迷藏，时不时，老狗还向小狗汪汪得喊两声，好像在说：“孩子们，别跑太远了，注意安全。”玩了一天的小狗们都累了，吃完饭，伸个懒腰，打个哈欠，投入到狗妈妈的怀抱里，小狗们很快就进入了甜甜的梦香，嘴里还时不时的发出咕咕的声音，好像在说梦话。

第二天早上，小鸟在枝头唱歌，叫醒了正在熟睡的小狗，它们打个哈欠，伸个懒腰，揉揉睡意惺忪的眼睛，又开始了一天的快乐生活。

瞧!多么快乐的小狗，真是幸福美好的一家。

保护动物，是我们人人都要做到的，许多人任意去猎杀动物，虽然现在的人都说要保护动物，但是还有很多顽固的人不听，继续猎杀动物，人类拿动物来观赏、卖钱，用兽皮做大衣但你们有没有想过，如果你是一只动物，却遭到了人类的猎杀，你会怎么想，你愿意吗，你愿意被猎杀吗？你绝对不愿意，有些人说：我又不是动物。但你们有没有想过动物们会怎么想吗？现在人类大量捕杀动物，动物会甘心吗？不，不会，永远不会。它们不愿意死在人类手里。它们愿意被你们猎杀吗？不，它们有一千个不愿意，一万个不愿意，一亿个不愿意

有些人虽然知道怎样去爱护动物，可是他们只会假惺惺地去教育别人，而自己却照样破坏环境，照样兴致勃勃品尝野味。就拿印度洋毛里求斯群岛上生活的渡渡鸟来说，由于它身上的肉鲜美无比，所以遭到当时人类的大量捕食，在十七世纪就已告灭绝。但是如果当时人们有动物保护意识的话，就不会造成渡渡鸟的灭绝。

还有鲸，鲸不是让你们随意捕杀的，鲸是被杀掉一头就死一头的，不像小鱼小虾那样多，如果我们把鲸杀掉了，那我们的子孙后代，他们不是看不到鲸这种动物吗？

现在，有些动物已经灭绝了，鳄鱼虽然凶猛，但人类更凶猛。就是因为有些动物身上的器官具有突出的经济价值，由此成为被人类掠夺利用的对象，成为动物灭绝的主要因素。鳄鱼长着锐利的牙齿，和硕大的食物胃口，我们都说鳄鱼可怕，但鳄鱼更怕人类，在人类的眼中，鳄鱼皮可以制成行李箱，手提包，钱包，鞋等物品，所以鳄鱼，现在已经成为快要灭绝的动物了。

《金色的脚印》，这篇文章讲了正太郎家捉来了一只小狐狸，两只老狐狸想尽办法就救出小狐狸，正太郎很同情小狐狸，他偷偷地给老狐狸投送食物，于是，他们之间建立了亲密，信任的关系，后来两只老狐狸救了正太郎，最后，小狐狸回归了大自然，两只老狐狸是多么高兴！这篇文章赞美了人与动物之间互相信任，互相帮助，和谐相处的美好关系，也展现了动物之间的浓浓亲情。我们就要向正太郎学习，他帮助动物，动物也救了他，这样不是很好么？为什么人们还是要捕杀动物呢？

在此，我呼吁人们，不要再破坏自然界中的花草树木，不要再乱杀一禽一兽，不要再杀害我们的朋友，要保护好自然界中的一个个生灵。消灭动物，就是在消灭人类自己。如果有一天世界上的动物全都消失了，那人类还能生存吗？要保护动物，珍惜这自然界里的每一个生灵吧。

朋友们，动物是大自然留给人类的无价之宝，它是我们人类的朋友。它们的生衍死灭与我们人类的生活是密切相关的。动物的大量毁灭对人类将产生严重的不良后果，造成生态严重不平衡，从而使人类的生存环境遭到破坏。让我们从现在做起，从我做起，保护动物，使世界变得更美好吧！保护动物，就是保护人类自己！

nimals 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.

动物是自然资源，在整个历史过程中，人类一直在糟蹋着这种资源。人们杀死动物，获得它们的皮毛，把它们当作食物或运动方式，或者只是因为它们碍事。成千上万种动物已经从这个地球上永远地消失了。现在另外上百种动物也上了濒危动物名单。仅荚国大概就有170种被认为处于危险当中。

为什么人们应该感到担忧呢?因为我们需要动物，因为它们一旦消失，就永远不会再出现。动物不仅仅是漂亮或有趣。它们不仅仅是人类的食物来源。在维持自然平衡中，每种动物都有其作用。毁灭某种动物会导致许多问题。比如，农民们如果杀死为数众多的鹰，他们谷物和粮食的仓库就会受到老鼠和田鼠的破坏。 为什么?因为鹰吃鼠类，没有鹰控制它们的数量，鼠类就会迅速繁殖。

幸运的是，有些人正在努力帮助拯救这些动物。有些组织筹钱以便人们了解这一问题。他们也努力使政府通过保护濒危动物的法律。很多国家已经通过了法律。这些法

律禁止杀害濒危名单上的动植物。某些濒危动物的数目正在慢慢地不断上升。

如今，人们过上了好日子，我们动物王国的生活却步履维艰……眼看着我们的国民体质每况愈下，国民种类和数量急剧滑坡，国内的蚂蚁团团转到了热锅上。于是，《申报》便在如此严峻的形势下诞生了！本报旨在提高人类环保意识，使其树立起辞不生态道德观。我们力图从精神文明方面着手，为“挽救家园大行动”略尽微薄之力。

报道一：还我飞翔的蓝天！

据历史记载，很久很久以前，我们鸟类的祖先头顶着的是“碧云天”，扇动着的“垂天之云”般的翅膀，真够逍遥啊！只可惜我们生不逢时，生长在台此污浊的年代，唉！无奈，只得泣涕涟涟！遥想大鹏鸟当年，抟扶摇而上，背负青天，而如今我们只能小心谨慎，夹着翅膀做鸟。闲暇睦是绝对不敢再一飞冲天，一鸣惊人了，因为我们根本不知道哪里有瞄准了鸟儿的枪口……

相关链接：两千多年前活跃在地球上的140多种鸟类，今天已经消失，而其中的1／3是最近50年内灭绝的。据动物王国统计局估算，目前濒临灭绝的鸟类已达530多种;据南飞的北雁观察，在中国的鄱阳湖，每年有30万左右的候鸟被杀害。多么可怕的数字！

报道二：陆地上，它们怨声载道

象：在西双版纳在这块充满贪欲的土地上，我们得拖着庞大的身躯不停地逃命。稍有止步，我们就会被分解成市场上的象牙、象骨、象皮制品……

虎：想当年，古人常称颂自已人“气吞万里如虎”而今我趄的是气吞万里！在东北老家，我们被捕杀的为数极少;在华南新家，兄弟们竟被关进动物园，学什么钻火圈的把戏。可恶有人啊，真想把你们撕得粉碎！

蛙：曾几何时，辛弃疾那老头在我的熏陶下留下了“听取蛙声一片”的千古名句，我们青蛙一族可谓百世流芳了吧！出人意料，我们竟被请入了广东的五星级宾馆，最后在绝望中死去，成为饕餮之徒餐桌上的佳肴，他们满足了口腹之欲，我们家族却日渐衰败。

相关连接：鸡豚狗彘之畜，统统跑来告状，怨声载道，只可惜篇幅有限，怎一个怨了得？

报道三：水上鸣冤----我要畅游！

我是一只鱼，水里的空气几乎让我窒息。

我是 一只大白鲨，二战时我爷爷曾救了一名溺海的军官,人类对我们顶礼膜拜.可现在,听说我全身都是宝,我常被鱼雷攻击.他们不是有个名词叫”感恩”吗?

我是一只海豚,在海洋馆里,我受尽折磨.人们让我表演,我不从,便不给饭吃,最终,饥饿战胜了我的勇敢与执着。

相关连接:由于过度捕杀和无可遏止的工业污染,242种鱼类濒临灭绝,大小黄鱼,带鱼,对虾成了珍品,一度盛名远播的黄海银龟,河蟹也几乎绝迹,我们丧失了畅游大江南北的权利。

编者后语;时间仓促,形势紧张,”申报”未能全面传达动物们的申诉之声,状告之意,广大读者大可又点及面,充分想象其他国民的艰难处境。

据说上帝创造天地之后,在第五天创造了动物,第六天才创造了人类的祖先亚当和夏娃.他们凭什么以大自然的主人自居?凭什么主宰我们的命运?哼!不在沉没中爆发,我们誓不为动物!

大自然是善良的慈母,同时也是冷酷的屠夫.人类改变了自然,自然注定改变你!只要人类与我们和平相处并尽可能给我们提供和创造良好的生存环境,我们便会给人类可多的回报,而不是伤害.

谨以此报献给尚未敲醒警钟的人们,愿他们从明天起,做一个环保的人,保护野生动物,树立生态道德观.

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!

我非常喜欢《我的野生动物朋友》这本书。它是1990年出生于非洲的法国小女孩蒂皮写的。蒂皮从小跟拍摄野生动物的父母在丛林里长大，与非洲野生动物和当地土著人生活在一起。

她非常喜爱野生动物朋友们。用她自己的话说：“我呢，爱鸟爱得不得了。我说爱得不得了，一点儿也不夸张，因为它们就像我的兄弟姐妹一样。这也没有什么出奇的，因为我就在它们当中出生，长大。非洲的野生动物是我最早的朋友，我对它们了解得可清楚了……”

蒂皮说：“我真不明白，人类为什么要杀死野生动物，真是荒唐极了……”是啊，野生动物并非是我们的敌人，而是我们不可缺少的好朋友。我们人类为什么要伤害它们呢 听说，有些地方的猎人为了更容易地捕杀森林中的猎物，不惜烧毁森林，杀死被烈焰逼得惊慌失措的动物。这样一来，不久以后，原本的森林就会变成了一片沙漠;还有些偷猎者猎杀国家保护动大熊猫、东北虎、藏羚羊和猎豹，只是为了用它们的皮毛换些钱……这样的事例还有很多很多。

当然，也不是所有的人都像刚才所说的那些人一样，现在有了动物保护协会，而且也有不少有爱心的人经常救助和收养一些动物。这样一来，就有不少动物得到了保护。

不管怎样，我希望大家都来保护动物。动物也是有感情的，它们受到人类的伤害也会伤心。而且地球不光是人类的，也是动物们的，它是我们人类和动物们共同的家园。我们没有权利夺走动物们的自由，动物们的家园。我们应该尊重每一个生命，保护动物就是保护我们自己。

保护动物

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。

这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，大家都十分喜欢它们。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，就就应爱护它们。”他的脸红了，并且回答说他不会再那么做了。

Space environment is the survival of humans we activities, such as: air quality, construction site, and the noise made by cars, water quality is good or bad, the streets clean and beautiful city, and so on belong to the environment. Now every day in newspapers and on television speaks the message of environmental protection, can be seen that the environment is very important to everyone.

Our upstream of the Yangtze river and Yellow River in recent years people cut down trees, not to protect the environment, make the Yangtze river and Yellow River upstream of the water and soil loss is very severe, Yangtze river flood, often have a lot of sediment in the Yellow River water. We in xinjiang tarim river is the longest continental river in China, the tarim river shore in iminqak is can be used to absorb dirt wont appear sandstorm, but people in the upstream of tarim river large area of forest cut water makes the river downstream dry, killing millions of acres of iminqak. It is barren land, to make more desertification. We in urumqi, family cooking, heating chimney come out large amounts of black smoke and exhaust emission of polluted air. Cant see the blue sky, the urumqi winter snow is black.

I saw on TV in South Korea restaurant use chopsticks are made of metal, can be used repeatedly. But in our country, large and small hotel is full use of disposable chopsticks, as far as I know a tree grow fifty years of birch only ten hotel with the number of chopsticks a day, how many restaurants are there in China? How much a day birch tree! !

To protect the environment, for students in our school must first from dont want disorderly garbage debris-brick, see someone littering to give him a reason. The adults also do not cut down trees, it will pollute the environment. To start from the save every drop of water, per kilowatt-hour, since the childhood to set up the consciousness of protecting the environment, to protect the environment, everyone duty. To make our home more beautiful!

环境是我们人类赖以生存的活动空间，比如说：空气的质量、工地和汽车发出的噪音、水质的好坏、街道的整洁和城市的美观等等都属于环境.现在每天在电视和报纸上都可以看见讲环保的消息，说明大家都很重视环境。

这几年我们的长江、黄河上游的人们砍伐树木，不保护环境，使得长江、黄河上游的水和土壤流失的很厉害，长江下游经常发洪水，黄河的水里有好多泥沙。我们新疆的塔里木河是我国最长的内陆河，塔里木河岸边的胡杨林是可以用来吸住泥土不会出现沙尘暴，可是人们在塔里木河的上游大面积开荒截水使得下游河水干枯，造成上百万亩的胡杨林死亡。至使本来就很贫瘠的土地，更加沙漠化。我们乌鲁木齐的人家做饭、取暖的烟囱冒出来的黑烟和汽车尾气的大量排放使的空气被污染。使乌鲁木齐的冬天看不到蓝天，雪也是黑的。

我在电视看见韩国的饭店用的筷子都是金属做的，可以反复用。可是在我们国家大大小小的饭店全是用的一次性筷子，据我了解一棵生长五十年的桦树只够十家饭店一天用的筷子的数量，中国有多少家饭店?一天要用多少棵桦树啊!!

对于我们校学生来讲要保护环境，首先要从不要乱人垃圾果皮纸屑，见到有人乱扔垃圾要给他讲道理。大人们也不要砍伐树木，这样会污染环境。要从节约每一滴水、每一度电做起、从小树立保护环境的意识，做到保护环境，人人有责。使我们的家园更美好!

保护我们的环境地球是我们的家园,我们必须照顾好它我们应该使减少污染,如我们所知大家在北美的垃圾进行1000公斤。大多数都是包装大部分垃圾变成土而不是塑料制品,塑料保持多年来它会污染我们的环境,所以我们不应该浪费我们应当做些事情回收利用。

Protect our enviorment The earth is our home,we must take care of it.We shoule make a less pollution as we know everybody in north America makes 1000 kilograms of the garbage everyday. Most of it is packaging Most of garbage turns into soil but not to plastic,plastic keeps for many years it will pollute our environment so we shouldn’t waste thing we should make some things for recycling .

My favourite animal is the panda,is our"national treasure",bacause pandas nive,lovable and lively,it was very likr it.panda is an ancient animal,is a zoologist called "living fossile " long ago there were many pandas in china,panda bamoo living area has large flowers,dead,threatening the survival of giant pandas.The whole world is extremely concerned about the rare giant panda rescue and transfer work.due to the destruction of the natural balance,climate warming,fewer and fewer panda.Panda is one of endangered animals,now only found in China,Sichuan,Shaanxi,Gansu,people began to conserve this endangered species.Today,the number of pandas has increased,but there is still a long way to go.Care for animals,is to protect human,we should be animals as mans best friend,to care,to protect them.Protection of animals is a duty of each person,let us work together to protect the giant pandas,giving them a good home.

Animals are our humans good friends, we cant hurt them, but some people are for your own sake, regardless of the poor little animals life and to trample them, kill them.

Remember that is one day this summer, I chat with grandma sitting on one side of the road, I saw a cat wanted to cross the street opposite of a piece of meat to eat, who knows, the cat just walked to the middle of the road, a large truck, the driver while riding on the horn, mouth scold a way: "dead cat to go away." Kitten also dont understand the meaning of the driver, the driver has been impatient, he put the pedal to a a small life is so dead in the wheel of a large truck full of cargo. I watched this scene was angry and sad, in order to commemorate the poor kitten, so I want to have this day - July 2, set up to protect the animals.

To this day each year, people all want to contribute to protect animals, to let the small animals spend the day with a light heart, cant let them hurt, small animal no matter by who, they are hospitable, finally, we need to use different ways to promote small animals to human help. Let every man in the world to protect small animals.

Im looking forward to this holiday was born at an early date.

动物是我们人类的好朋友，我们不能伤害它们，但有些人却为了自已的利益，不顾那些可怜的小动物的生命，去践踏它们，捕杀它们。

记得那是今年暑假的一天，我和姥姥在公路的一边坐着聊天，我看见一只小猫想穿过马路去吃对面的一块肉，谁知，小猫刚走到马路中间，一辆大卡车过来了，司机先生一边按喇叭，一边嘴里骂道：“死猫走开。”小猫还没理解了司机的意思，司机先生已不耐烦了，他一踩油门，一个小生命就这样死在了满载货物的大卡车的车轮下。我看着这一幕又气愤又伤心，为了纪念这只可怜的小猫，所以我想把这一天——7月2日设立为保护动物节。

到了每年的这一天，人们都要为保护动物做贡献，要让小动物轻松愉快地度过这一天，不能让它们受到伤害，小动物不管到了谁家，人们都要热情招待它们，最后，我们还要用各种不同的方式去宣传小动物对人类的帮助。让世界上的每一个人都要保护小动物。

我盼望这个节日早日诞生。

亲爱的同学们：

如果朋友有了困难，你会袖手旁观吗?如果朋友遇到危机，你会见死不救吗?我想你当然会说：“不会!”

现在我们人类的朋友——动物，有的已濒临灭绝，有的数量急剧减少，很难想象：如果有一天，人们生活在一个没有动物，没有植物的城市沙漠中，生命将逐渐枯萎，色彩将消失……

同学们为拯救动物，拯救人类，拯救唯一的地球赶快行动起来吧!因此我提出以下几点建议：

1、我们小学生要积极学习和大力宣传《野生动物保护法》，让更多的人了解并遵守这个法律。

2、现在有许多卖田鸡的。田鸡又叫“青蛙”，它可是人类的老朋友了，所以我们不仅不应吃它，还应告诉大家爱护它。

3、目前，伤害鸟类的事时有发生，致使许多小鸟无家可归，我们应该给小鸟做些巢，让它们安家落户，为人类做更大的贡献。

4、如果我们在路上遇到了小动物，我们应该做到“三不”：不恐吓、不打击、不捕捉。

5、如果我们捡到或发现了珍贵的野生动物，应及时向居委会、学校及有关部门报告。

我想：只要大家自觉遵守《野生动物保护法》，自觉维护生态环境，那么我们的祖国，我们的未来会更加美丽富饶。

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。

清明节时，我和妈妈去艾山游玩。我们来到了艾山，但并没有直接进去玩耍，而是在外面大略的浏览了一下。在艾山门口的右边，有一片桃花林，站在高处向下眺望，桃花林仿佛一片花海。当我仔细看的时候，发现桃花林里有许多垃圾。突然有一个青年人走进桃花林，手里还拿着一些零食，他一摆手，后面有几个男生和女生走了过来，他们手里拿着许多吃的东西，其中一个男生吃完东西，就将袋子随手一扔，我看见了就说：“这些桃花林是让人欣赏的，而不是让你们随意扔垃圾的。”那几个男生一听到这话立刻就跑了，然后我在一块木牌上，帖上这样几个字“保护桃花，让世界充满色彩。”我把它插在桃花林前，希望人们能够注意到它，我们看完了桃花，又在艾山门口逛了一下。在艾山门口，有一些人摆着小摊卖的小蝌蚪。有很多人围在那里异口同声的说：“好漂亮呀。”我快步的走上前，旁边一个五六岁的小女孩笑着说：“哇，好可爱的小蝌蚪呀，我要买5只。”我挤进人群里，对卖小蝌蚪的人说：“叔叔，小蝌蚪不能买。”叔叔抬起头对我说：“小蝌蚪为什么不能卖？”我很有耐心地跟叔叔说：“因为小蝌蚪长大以后能变成青蛙，青蛙被称为农田卫士、害虫天敌，按品种的不同，一只青蛙一年可以吃到，5-40万只害虫，在稻田中，放养适量的青蛙，这样不仅可以减轻农作物病虫害，而且可以避免因喷洒农药所造成的环境污染，青蛙不仅是农田卫士，害虫天敌，他那熟悉而又悦耳的蛙鸣，其实就如同是大自然弹奏不完的美妙的乐曲，是一首恬静而又和谐的田野之歌。”我说完，叔叔惭愧地走了。朋友们，让我们一起来保护环境，保护动物吧！

[保护环境和动物二年级作文

ver 70% of the Earth’s surface is water; water is obviously the most precious natural resource that exists on our planet. Without water, life on Earth would be non-existent. Water is the lifeblood of the environment, essential to the survival of all living things-plants, animals, and human. Although we recognize this fact, we disregard it by polluting our rivers, lakes, and streams. Afterward, we are slowly but surely harming our planet to the point where organisms are dying at a very alarming rate, and our drinking water has become greatly affected. In order to fight against water pollution, we must understand the problems and become part of the solution; we also need to do everything possible to maintain its quality for today and the future.The government alone cannot solve the entire problem; it’s up to us when it comes to the problems we face with our water. In your home, correctly dispose dangerous household products. Keep paints, used oil, cleaning solvents, pool chemicals, and other dangerous household chemicals out of drains, sinks, and toilets because many of these products contain harmful substances. In your yard, recycle used motor oil. Avoid pouring waste oil and resist the temptation to dump wastes onto the ground.These are just a few of the many ways in which we, as human have the ability to combat water pollution. If these measures are not taken and water pollution continues, life on Earth will suffer severely.

[关于保护生态环境的英语作文

昨天傍晚，发生了一件很不愉快的事情。

有一户人家住在四楼，家里面养了一只可爱的小狗。可能是因为受到惊吓的缘故，那只小狗不停的叫。使得这户人家的主人非常生气。最后，那个主人在一气之下，把这只小狗从四楼的阳台上面丢了下去。小狗当场就不再叫了。我们跑下楼看看这只小狗的时候才发现。这只小狗还没有死亡，这使我们感到很欣慰。可是那个狗的主人也急忙跑下楼，把这只奄奄一息的小狗丢进了垃圾箱。

当时，我居然好恨那个人。我萌生了一个念头：既然不喜欢这只小狗，为什么要把他领养回来。就算领回来了，又不喜欢了，也可以把这只只小狗放生啊!为什么一定要害死它呢?

对于人来说，杀死一条狗根本不算什么大事，在某些人眼中甚至可以认为是再平常不过了。可是，就算是一只小狗，也是有生命的。万物皆平等啊!没错，人是高等动物，是有思想，有知识的。可是正是这些有思想的人，残忍的伤害了一条生命。

但是，也不是所有的人都会这样。很多人还是把小狗和其他的动物，当作是我们人类的朋友。或许，今天人们伤害的只是一只小动物，大家都习以为常。可是，那些病毒的侵略，还不能惊醒世人吗?人们伤害野生动物，甚至还有些人吃食野生动物，才会引起这些病毒的滋生。

如果所有的人都可以像爱动物者一样爱动物，那么这种悲剧就不会在重蹈了。

Good environment can make people feel happy and fit 。 To improve the environment means to improve our life。

We should plant more trees and flowers around us 。 We shouldn’t cut them down 。 We should stop factories from pouring waste water into the river and waste gas into the air。

Whenever we see litter on the ground ， we should pick it up and throw it into dusbins。 Never spit in public。 Don’t draw on public walls。 It’s our duty to protect the environment。

在地球上，除了人类，还有什么呢?没错，还有动物。可几年下来，动物的数量逐渐下降。人类有没有把动物当朋友看呢?

动物和人类应该是好朋友，可为什么动物会和人类为敌呢?是因为人类没有把动物发在眼里。比如奶牛。人类用奶牛生产奶牛，可等奶牛没有奶的时候，人类就会把奶牛残忍地杀死。奶牛没奶时，不会将它放生吗?奶牛也是一条活生生的生命啊!近几年的“鼠疫、艾滋病、疯牛病、禽流感”，这些都是动物们奋起反击的预兆呀!难道人类还要打第三次世界大战吗?我们的祖先就是高级动物呀!如果人类再不制止这种滥杀动物的行为，是对我们的地区母亲沉重的打击呀!

我们现在不要再破坏动物的家园，这样动物们就可以安心繁殖后代。朋友们，还动物们一片蔚蓝的天空，让小鸟自由地飞翔;给动物一片绿草地，让牛羊欢快地奔跑;还动物一片汪洋，让动物无忧无虑地畅游海洋之中。也许，这样可以安抚动物们受伤的心灵。动物原本不坏，只是人类破坏它们的家园，这些只是它们对人类的“报复”而已。

朋友们，让我们一起保护动物吧!

让我们走进动物王国，倾听动物们发自内心的呐喊可爱的海豚说：“我来自蓝蓝的大海，我珍惜现在拥有的这个温暖的家，我发自内心地、由衷地号召大家—爱护这个美丽的大海!”英勇的雄鹰说：“我是高空中的勇士，湛蓝的天空、洁白的云朵构成一幅美丽的画，我爱这个美丽的家。请大家珍惜这个家—辽阔的蓝天—我们共同拥有的家!”蹦跳不停的松鼠说：“我是森林中可爱的小精灵，高大的树，为我遮阳，树下还开了一些可爱的小花;绿色丛林、欢乐的家，请大家不要伤害这个属于大自然的家;让我们共同珍惜这个美丽的家!”

(现今)比目鱼可怜巴巴地说：“我原住在广阔的大海里，可现在，大海给黑色浑浊的水污染了，我不得不离开了这个美丽的家。难道人类的良心给狗吃了吗”，比目鱼突然情绪难控“你们住高楼大厦，却不让我们安宁。呜呼!把家安在哪儿呀?”机警的白鸽“咕咕——”愤怒地说：“你们无情的人类，不给我一天清新的空气，地球妈妈的‘衣裳’(大气层)都快破了。人类真是不孝之子!”重病在身的老虎带着沙哑的声音说：“可恶的人类!杀了我一家老老少少，连我的尾巴也给人类的枪打断了，我无家可归，哪一天，我也可能死在人类的抢下。我成天提心吊胆，不得安宁……”说着，咳嗽连连。

人类们，问问自己良心吧!换作你是动物，你又会怎么想呢?总有一天，这种灾难也会降临在人类身上!在此，我呼吁：保护动物，保护大自然，人人有责!全人类行动起来吧!把动物赶尽杀绝—这种行为是低级的、是愚蠢的，不是高级动物—人类干的，反省反省自己吧!让我们好好珍惜共同拥有的美好家园吧!
