五年级保护动物的英语作文汇编20篇

Animals and human beings, we have thought, have feelings, also have their own way of life, more freedom.

We should not to destroy their peaceful and harmonious life, we have no right to destroy their life, of course, there is no reason to blame hurt them more.

Whenever we place series of delicious food on the table, such as: snakes, frogs, and other animals. Should we think of it, each of us to eat a kind of animal, how much is to go to farmers for banker harmful insects. We are not should the perspective-taking once, they are in a concerted effort to catch insects, can human beings not only ungrateful, instead put them as their food, as we human beings every day to make money, how they are evil!

Today, many of the earths biological already very rare, even have already endangered! If there are no animals on the earth, the earth will become what kind, humans will become like?

I think its time for us human to reflect, if continue like this, we will be the enemy of the animals, more dont talk about what "dances with wolves"

Human, hurry up wake up! Protect wild animals, now, still in time!

动物与我们人类一样，有思想，有感情，也有它们自己的生活方式，更有自由权。

我们不应该去破坏他们安详和谐的生活，我们也无权去破坏他们的生活，当然，更没有理由去指责伤害他们。

每当我们的饭桌旁摆上一道道香喷喷的菜，比如：蛇、青蛙、等动物。我们是不是应该想一想，我们每吃一种动物，就等于放走了多少对农民对庄家有害的虫。我们更是不是也应该换位思考一下，它们都在齐心协力的抓害虫，可人类不但不领情，反而把它们当做他们的食物，当作我们人类每天赚钱的东西，他们是多么可恶呀!

如今，地球上的许多生物已经很罕见了，甚至有的已经濒临灭绝了!如果地球上没有了动物，地球将会变成什么样，人类又将会变成什么样?

我想，是我们人类好好反省的时候了，如果再这样下去的话，我们将会成为动物们的敌人了，更别谈什么“与狼共舞”

人类，快点醒醒吧!保护野生动物，现在开始，还来得及!

人与自然有着密不可分的关系，一直以来，人类的生存与发展都离不开自然。自然有着丰富的资源供人类不断地开发利用，同时它不断给人们以优良新鲜的空气来生存。可以说，没有大自然，就没有人类今日的辉煌。

可悲的是，人类在利用自然时，大大地忽略了自然界的生物，为了牟取暴利，多少人昧着良心残忍地将动物杀害。眼见着藏羚羊只剩骨肉的尸体堆积如山，要的只是一张美的皮毛；老虎数量大幅度地减少，由原先的数以万计到如今的寥寥无几，为的就是虎皮和虎骨。或许那些人的良知早已泯灭，但这一幕幕生灵涂炭、不堪入目的场景不能令我们为之震撼、激愤？金钱能蒙蔽良知，却掩盖不了这悲剧不断地发生、重演。

我一直认为，爱护动物就是保护我们人类自己。试想一下，当地球上只有人类，再无其他生灵时，会是多么悲怆啊！再者，所有的生物组成了一条完整的食物链，人是最高统治者，但当一种又一种的生物灭绝时，食物链必是越来越贫乏，久而久之，当食物链只剩下人时，可想而知谁是盘中餐了吧。

俗语说得好：食在广东。广东一直是美食集锦之地。尤其是野味，在人们眼里是上好的补品，不仅营养丰富，而且味道与众不同。但毕竟是野生动物，在深山老林里带些病毒、寄生物是件平常之事，但一被人吃下去可就不得了了。例如闻其色变的“SARS”病毒就是野生动物传播的。

无论如何，保护动物已成了义不容辞、当务之急的事了，只有人与自然和平共处，才能不断发展、生存下去！

With the continuous development of science and technology, the increasing number of cars, emissions of emissions has caused serious pollution, perhaps, a few years later generations, hundreds of years after everyone, perhaps because of air pollution and death. Now, twenty percent of the people on earth every year are killed by drinking contaminated water, and if this continues, will the earth become bare after tens of thousands of years, like the moon?

According to the statistics of scientists, every year, more than 20 percent of the trees are withered by exhaust pollution every year. More than eighty percent of our useful bacteria die, and everyone may feel very exaggerated, but it is true. Followed by contaminated waste water, waste gas and so on. Is human error?

How much I hope that we can cherish every thing around us, every animal, every beneficial bacteria, because it is possible, in tens of thousands of years later today, they are gone.

Animals have warned against humans;

Bacteria have warned against humans;

Every innocent life warned us.

"Human, do not harm yourself, do not kill us again!"

随着科技的不断发展，汽车的不断增多，排放的废气已经造成了严重的污染，或许，几年后的子孙后代、几百年后的大家，或许会因为大气污染而死亡。现在，地球上每一年都有百分之二十的人因为饮用了受到污染的水而死亡，如果这样延续下去，地球在几万年后岂不是变得光秃秃、像月球一样了?

据科学家的统计，每一年，每一月都有百分之二十多的树木因为废气污染而枯萎。百分之八十多对我们有益的细菌死亡，大家或许会觉得很夸张，但这是事实。其次还有受到污染的废水、废气等。人类有错吗?

我多么希望大家能珍惜我们身边的每一个事物，每一只动物，每一只有益的细菌，因为，很有可能，在几万年后的今天，他们都没有了。

动物对人类发起了警告;

细菌对人类发起了警告;

每一条无辜的生命对我们发起了警告。

“人类，不要再害你自己，不要再害死我们了吧!”

[保护环境的英语作文2篇

亲爱的人类：

你们好!

不知你们是否看到过这样一副画面：广阔的蓝天，飘着朵朵白云;郁郁葱葱的山林中，一只只活泼可爱的小动物欢快地跳跃着、奔跑着。这是一副多么美好的画面。然而，现在这样的画面少得可怜，更别说能亲身与小动物们接触了。这是为什么?是因为人类对大自然的破坏——大肆砍伐树木，盲目地猎杀动物。

无知的人类呀，同样是生命，只不过一个是主宰者，一个是动物，却有如此大的区别。难道已丰衣足食的我们，非要忍心让他们无家可归?同样是生命，难道就不能与他们和谐共处?我难以想象，再这么下去，只剩下了孤独的人类地球会变成怎样?世界会变成怎样?在一片荒凉的大地上没有一丝植物的踪迹，昔日的小精灵也不知去向，大地一副死气沉沉的样子。风沙来了，没有办法;寂寞难熬，也没有人让你吐诉心声的。动物也是有感情，也是有心声的，假如换作是你，看到家园毁灭，伙伴去世，还会无动于衷吗?除非你是用铁做的心。但是，动物们只有默默无声地忍受着，忍受着命运如此不公的安排，没有一丝怨言，任凭生命中的每一样宝贵的东西消失，却毫无办法。人类啊人类，难道你们还没有觉悟吧?

“退一步海阔天空”，让我们从现在开始，从身边开始，从一草一木开始，为动物们，也为自己创造一个美好的家园!相信在不久的将来，小动物，小精灵，将成为我们生活中的不可或缺的乐趣，我们互相倾诉心声的好朋友。

努力吧，每一位有血有肉的中国人!

Do you like animal？ What’s your favorite animal？ My favorite animal is monkey. It is lovely and clever. People always say that our human beings are evolved from monkeys. In the other word， monkey looks a little like human being， which close the distance between it and me. It has a long tail. It can make different shapes by it. It likes eating bananas. It will peel off the skin just like human being. It is funny！ I love it.

I am a student in Huaxing Middle School. Do you know the plastic bags? Do you often use the plastic bags? I don’t like them. I think they use the wasting valuable oil their production. And they can’t decompose(分解) in a short time. The plastic bags will make our world worse. I agree with the rule, which people can’t get the free plastic bags in the shops, supermarkets. It encourages people to use their cloth bags and baskets. It’s good for our environment.

So I hope all the students in our class stop to use the plastic bags, and use our own cloth bags. I hope we can take care of our environment.

Let’s make our world more and more beautiful.

I have a beautiful school.

In the spring,the weather become warmer and warmer.And the trees become green.Some birds are singing on the trees.The flowers are open.Some butterflies are fly over the flowers.In the fall,the weather is windy.The leaves of trees like butterflies are in the sky.

What a beautiful school is!I like my school.

一年中有许多节日：快乐的儿童节、团圆的中秋节、热闹的春节……而我要设立一个与众不同的节日——保护动物节。

我从小就喜爱动物。常常吵着买动物书，去动物园，看到一只瘸腿的纺织娘都要伤心，吵着妈妈为你它绑纱布。每次，看到那些可爱、漂亮的的小动物，我就觉得他们真可爱，大自然有了它们真幸福。

那天，我兴致勃勃地收看《动物的生命》。电视中介绍着一个个有趣的动物，这些动物时而奔跑，时而争斗，时而戏耍……可是后来，我看到这样令我心惊胆战的一幕：一群非洲人正在追赶一只黑犀牛，犀牛拼命逃命。突然，一颗从天而降的子弹直射在犀牛的身上，一击命中，一个非洲人走过去，不顾犀牛的悲鸣，用一把匕首把犀牛的角切了下来。非洲人看了看手中的牛角大笑：“这一定能卖个大价钱……哈哈哈……”转身开车而去。我不忍心再看下去，眼前总是浮现起犀牛那无助的眼神，血肉模糊的脑袋。我不明白：“人类呀人类，为什么偏偏要杀死我们人类的朋友——动物，他们也有生命的呀?”突然，我的脑海里产生了一个强烈的念头——对了，我们要保护动物，灵机一动：应该可以建立一个保护动物的节日!

保护动物节来了，这天，每个人的心中都有着“爱护动物”的信念，哪怕一只小小的蚂蚁我们都可以投去爱的目光，那天饭桌上不能有肉类。大街小巷的电视屏幕上要循环播放保护动物的频和口号。大家在这一天要进行慈善捐款，成立“基金会”，用这些钱去建立自然保护区，大家还可以去动物园认养一只动物。好多同学都上街进行宣传保护动物，每个人心中都牢记保护动物的责任……

我真希望你也能支持我，让我们一起来保护动物吧!

When the Arctic Ocean freezes over in the autumn, polar bears set off in search of their favorite meals: fatty ringed seals and bearded seals. By the summer, the sea ice begins to melt and break apart. Deprived of access to the tasty seals, polar bears spend the summer fasting. At least, thats whats supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So whats a hungry bear to do?

Scientists once thought that polar bears might survive by supplementing their pinniped diet by turning to terrestrial foods like snow geese, their eggs and caribou.

"Weve had this debate in the literature about whether terrestrial foods are nutritionally relevant to polar bears during the on-land season when the ice has melted."

University of Alberta biologist Nick Pilfold.

"And weve known for a long time, going back to research in the early 70s, even going to back to early explorer logs, that polar bears will consume terrestrial based foods. But the debate was always whether those foods actually add up, energetically." In other words, do these substitutes provide enough nutrition to make up for the lost seals?

To find out, Pilfold and his colleagues estimated the weight lost each day by polar bears in the wilds of western Hudson Bay during the ice-free season, when they could ostensibly be chowing down on terrestrial foods. Then they compared that to the weight lost by bears that are temporarily held in Manitobas Polar Bear Alert Program.

While captive, the bears do not eat. They drop about one kilogram each day. But the wild bears, who had access to the Arctic snack bar, lost the same amount of weight each day. The results are in the journal Physiological and Biochemical Zoology.

"Which is really saying that the terrestrial foods do not have dense enough energy to offset the mass loss. So this idea that bears can just switch from eating sea ice–based food to land food and thats going to help supplement against longer ice-free seasons, that really doesnt show up in the data."

The problem is that polar bears evolved to rely on the marine diet.

"The food on land is protein and carbohydrate based, and the food the polar bears really focus on is fat. Fat is the name of the game for these bears; theyre highly adapted to absorbing that fat into their system and putting it onto their body as body mass, so they can fast on it later on. And the only thing thats going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when theres sea ice."

Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, cant last as long without sea ice. So as the Arctic warms, younger polar bears will disproportionately die out. Leaving the species survival in doubt.

北冰洋在秋季结冰以后，北极熊就会出发去寻求它们最喜欢的食物：富含脂肪的海豹和胡子海豹。海冰在夏季开始融化断裂。这使北极熊在夏季无法吃到美味的海豹，所以它们进入禁食期。至少，情况应该是这样。但是由于地球变暖，温暖的无冰季节越来越长。那饥饿的北极熊要怎么办?

科学家曾经认为，北极熊可能会转向陆地上的食物来补充它们对鳍足类动物饮食的需求，进而生存下去，这些陆地食物包括雪雁、雪雁蛋和北美驯鹿。

“文献中有过这类辩论，即在寒冷融化时陆地食物是否能满足北极熊的营养需求。”

尼克·皮尔福德是加拿大阿尔伯塔大学的生物学家。

“通过上世纪70年代初的研究，还有早期的探险者日志，我们很早以前就知道，北极熊会以陆地食物为食。但是辩论的焦点在于，这些食物是否能增加北极熊的能量。”换句话说，这些替代食物能否为北极熊提供足够的营养，弥补不能进食海豹带来的损失?

为了解开这个疑惑，皮尔福德及同事对西哈德逊湾荒野地区的北极熊在无冰季期间每天失掉的体重进行了估算，从表面上看，北极熊在这段时间食用了陆地食物。随后，他们将这一数据与通过马尼托巴北极熊预警计划暂时捕得的北极熊所失掉的体重进行了对比。

在被关期间，北极熊不吃东西。它们的体重每天大约下降1公斤。虽然野生北极熊能享用北极“小吃”，但是它们的体重每天也同样会下降1公斤。这一研究结果发表在《生理学和生化动物学》期刊上。

“显然结果表明，陆地食物不能为北极熊提供足以抵消大量损失的能量。所以，北极熊可以从食用海冰下面的食物转向食用陆地食物，并帮助它们对抗日益延长的无冰季这个观点，并没有在这项数据中得到证明。”

问题是，北极熊进化成了依靠海洋食物的动物。

“陆地食物以蛋白质和碳水化合物为基础，而北极熊需要的食物以脂肪为主。脂肪是这些熊真正需要的东西;它们高度适应的情况是，将脂肪吸收进它们的系统中，然后把这些脂肪放在身上以增加体重，这样它们之后就可以依靠这些脂肪来度过禁食期。唯一能提供给北极熊这种脂肪的就是海洋哺乳动物。但是它们只能在有海冰时食用到这些海洋哺乳动物。”

成年北极熊可以8个月不进食。但是小一些的未成年北极熊已经不再被哺育，它们必须要去猎食，可是它们不能在漫长的无冰季期间一直不进食。所以，随着北极地区变暖，较小的北极熊将会大批死亡。这使这些物种的生存成为问题。

Today, I went to the park with my parents. I saw monkey, giraffe and so on. When we took a break in the lake, I saw a lot of goldfish in the lake. People threw food into the water, then suddenly all the fish came and ate the food. It was a crowd of fish, and I was shocked, but then they went away quickly.

今天，我和父亲母亲去公园了。我看到了猴子，长颈鹿等。我们在湖边休息的时候，我看到湖里有许多金鱼。人们把食物扔到水里，突然所有的鱼都来抢食物。很大一群鱼，我震惊了，不过很快它们就散开了

I like the program" Animal World" . First of all, I like animals, especially small animals. Secondly, the host is able to make the program lively and interesting. Thirdly, through this program I know a lot of things that I havent known before. I gain some knowledge about animal life, such as, different lives of various kinds of animals, the relationship between people and nature, people and animal, and the importance of animal protection.

I want to say that animals are part of nature as we are. They can not be separated from the humans. We must keep nature in balance.

Please give your love to animals. Stop killing them.

我喜欢“动物世界”这个节目。首先，我喜欢动物，尤其是小动物。第二，主持人把节目办得既生动又有趣。另一方面，通过这个节目，我知道了许多以前不知道的关于动物生活方面的事情，例如不同动物的不同生活习惯，人与动物之间、人与自然之间的关系，还有保护动物的意义。

我想说的是，动物是自然的一部分，它们与人类不可分割，我们一定保持生态平衡。

请把你们的爱给它们吧，不可以杀害它们。

My favorite little animal - the turtle, I gave it a name called "Li Shijan", usually I call it "extension". It is not just a lovely shape and it can sometimes understand my words! Its head small, neck thin, but also carrying a bowl like the size of the shell, green, pointed little tail It is very interesting to start the road.

Although it is only a small animal, but it also has a good heart. Once a grandfather was hospitalized, it was hunger! Even if we had bought it the most favorite loach fish, it would not have eaten it. Until the grandfather half a month after discharge, it was happy to eat, when the devil is really like people love and pity.

But sometimes it is also "hateful"! One day, it is in the glass cylinder hold the uncomfortable to come out, I see it anxious look like to help it, I use the index finger and thumb carefully pinch its shell, light I did not want to come out, did not think that it was with a sharp claws to scratch me, really do not know good people! Although I am very angry, but to see it happy on the ground free to play everywhere, I am also happy for it The

This is my favorite little animal - the turtle "extension". Do you like it?

同学们，想像一下吧，如果全世界的动物都没有了，生机勃勃的的世界会怎么样呢?听不见小鸟的鸣叫，看不见小鱼在活泼的游来游去，闻不到臭鼬臭粠粠的身子，摸不到小兔温暖的毛，很多关于动物乐趣，将再也享受不到了，所以保护动物真的很重要。

动物虽然不会与人类交流，但要是人类在动物有困难的时候帮助他，他也会帮助你。特别是狗，你和它生活久了，它就会把你当成自己的家人。有一部电影叫《忠犬八公》讲的是一个真实的故事，有一只狗，叫小八，它的主人对它精心照顾，小八每天送主人到火车站，接主人回家。有一天，主人生病去世了，没回来，小八就一直等呀等，还是没等着。最后，它每天去火车站，风雨无阻，等了整整十年，直到死去。一条多么让人敬佩的狗哇!

动物对人类这么友好，人们呢?毫无感谢之语，反而会杀害小动物。比如：取熊胆，就是把熊的胆汁取出来，熊每天都非常痛苦，许多熊都自杀了。还有海豚湾里的海豚，日本人最喜欢吃海豚里的一块肉，所以把它们杀了，鲜血直流，染红了大海。还有拔象牙，把拔掉的象牙拿去贩卖，把老虎杀了，拿它的骨头做药等。我们也会伤害一些小动物，把色彩缤纷的蝴蝶抓起来，关在铅笔袋里;把匍匐前进的蚯蚓踩死;把翩翩起舞的飞蛾翅膀折断等等，不管动物小不小，丑不丑，我们都要保护它们。

同学们，勿以善小而不为，勿以恶小而为之。动物是我们人类的朋友，动物能带给人们幸福，带给人们友谊，带给人们欢乐。让我们行动起来吧!一起携手，保护动物。

This afternoon, I turned on the computer on the qq, and saw in qq space "simply make the gods cry".

Some people are ready to take the little bears bile. At that time, break the cage, a mother bear with huge PAWS strangled little bear, then her head hit the wall and died. Maybe it is their best way to them, because they are relieved.

After I read this story, I almost cry. So cute teddy bear, so the great bear, who is cruel killed them? Is human. Who is the one who claim to protect giant pandas? As humans. This is not a contradiction? The giant panda is a national treasure in our country, but as soon as I saw some pandas humans want to flee. Why is this? Because someone hurt the panda.

The panda is so cute! They also have life, they are not rich. We must protect the panda, some panda has been found, there are some pandas still suffer from the endless pain. We want to be treated, if they are they, by this pain?

Here, I appeal to everyone: love animals, let animals no longer afraid of us, let the world become real peace!

At the same time I also urge those who hurt the panda: panda also have life, pandas have feelings. Their value is not let us make a living, but live for yourself. I hope you can stop here!

今天下午，我打开电脑上了qq，，在qq空间里看见了“惊天地泣鬼神”的一幕。

一些人准备取小熊的胆汁，这时，一只母熊挣脱了铁笼，用巨大的熊掌掐死了小熊，然后把头撞上墙壁，死了。也许这是它们最好它们的办法，因为它们解脱了。

看完这一则故事，我快哭了。这么可爱的小熊，这么伟大的母熊，是谁狠心夺走了它们的生命?是人类。口口声声说保护大熊猫的是谁?也是人类。这不是自相矛盾吗?大熊猫是我国的国宝，可一些熊猫看见人类就想逃。这是为什么?因为有人伤害熊猫。

熊猫是多么可爱啊!他们也有生命，它们不是致富的工具。我们一定要保护熊猫，一些熊猫已找到，还有一些熊猫还在受那无尽的痛苦折磨。我们要将心比心，假如自己是它们，受到这种痛苦会怎么样?

在这里，我呼吁大家：爱护动物，让动物不再惧怕我们，让这个世界变得真正和平吧!

同时我也奉劝那些伤害熊猫的人：熊猫也有生命，熊猫也有感情。它们的价值并不是让我们赚钱，而是为自己而活。希望你们能到此收手!

今天夜晚，我和爸爸在电脑上查了对我们有益的小动物，我们在网上找到了许多对我们有益的小动物，比如：蜻蜓、燕子、青蛙、蚯蚓、蜜蜂、蛇、猫头鹰、啄木鸟等。下面就说说它们对人类有哪些益处吧！

蜻蜓生活在水边，扑捉蚊子等小飞虫，免得叮咬人畜，传播疾病；燕子是候鸟，专门扑食空中飞虫，如；蝗虫、蚂蚱等害虫；对农作物生长有益的青蛙生活在稻田里，每天能吃70多条害虫，是农民伯伯的好帮手；啄木鸟是森林的好医生，它们可以从树掏出蛀虫来，每天吃上千条害虫，好厉害啊！猫头鹰专吃传播疾病和破坏庄稼的老鼠……。

这些小动物可都对人类有益的，为人类作出了贡献哦，它们都是我们的好朋友，我们一定要好好地保护它们。首先，我们要爱护环境，让这些小动物有安身之处；其次，我们小朋友还可以成立保护小动物的队伍，宣传小动物对人类的益处，告诉别人不要扑食这些小动物……当然，可行的措施还不止这些，希望所有的人都行动起来，为保护好小动物献计献策。

我爸爸从市场上给我买了一只小乌龟，我高兴极了。

这只小乌龟非常可爱。大大的龟壳，小小的脑袋，还有有力的四肢。让我疑惑不解的是小乌龟不胆小，我用手碰它的头，它也不肯把头缩回去。小乌龟全身碧绿，只有肚子比较白。眼睛比较小，它的眼睛一只睁着，一只闭着，我想它可能是生病了。

有一次，我给小乌龟换水，我把小乌龟拿出来，它却想把头伸过来咬我的手，我想它可能饿了，便让妈妈切一块肉，我就让乌龟把肉叼住，可是它咬住了并不往里吞，我觉得小乌龟比较笨。

我很喜欢我的小乌龟，我希望能让小乌龟多活几天，但不幸的事情发生了。

一次我给它换水，发现它一动也不动，我好奇的把小乌龟放在深水里，我想它应该会吐一个气泡，结果它没有吐气泡，还是一动也不动，我想它已经死了。

我很伤心，因为跟它在一起很好，我本来想让它多活一会儿，结果它却在今天死了。

我想人们有工夫养它（动物），就要好好养它，就不要放弃它。阳台旁边的一群猫

去年，在夏天，我在阳台晒太阳，忽然，我看见阳台前的花园出现几只小猫在玩耍，还有一只大母猫在放哨，我想这只大猫就是它们的妈妈吧。我把这件事告诉了妈妈，妈妈说：“你要喜欢的话，可以天天给它吃的，让小猫们还有大猫信任你。“我向妈妈要了一点牛奶还有剩的鱼拿去喂它。我刚走过去，看见猫早就没了，我只好把奶还有鱼放在两个盘子里，放在它们能看见的地方。不一会儿，那几只小猫还有大猫都出来了，是大猫先看见食物的，首先，它叫了几声，好像在说：“有人类给咱们食物了，快来吃吧。“小猫们立刻跑到食物跟前狼吞虎咽的吃了起来。它们一定好几天没吃了。

就这样，它们每天都来玩，来吃饭，日复一日，它们变胖了，它们已经跟我们熟了。

一次我在花园玩，忘了关门了，回来的时候，我发现家里有四只猫，，两只是花的，一只是黑的。我想去给它们挠痒，但是它们都走了，只有两只猫留下来，一只大灰猫，一只小花猫。一个月以后，只有一只常到我们家串门。

我想，动物们需要自由，不要把它们关在某个地方，要爱护动物。

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.

寒假里，妈妈让我教弟弟学英语。这可真是一件苦差事呀!因为弟弟英语不太好,他平常又不用功。

那天中午，我开始教弟弟学英语了。我说：“Glad to see you。”弟弟却说：“Glag to she you。”我听了很生气，说:“不是‘Glag’,‘Glad’，另外不是‘she’，是‘see’。”弟弟虽然把“Glad”改过来了，可是“see”仍是改不过来。我说“see”，他呢，偏偏说“she”，好像成心气我似的。我让他看着我的嘴，看看我是怎么发音。他看了一会儿，改了过来。可是过了一会儿，又读成“she”了。我说：“不是读‘she’，而是‘see’,把舌尖稍微翘一点，舌头的两边放到牙齿的两侧，牙齿的中间留一点空隙，开始发音，就发出‘see’了。”

弟听了，似乎明白了，好不容易发出了“see”。过了一会儿，我又指出“see”让弟弟读，弟弟读出了“see”，我高兴的说：“弟弟终于改过来了，这可真是太好了！”

又叫了一会儿，弟弟不耐烦了，吵着说不学了。我灵机一动：要不学着英语老师那样，一边讲，一边做游戏。于是，我就把我的想法说给弟弟听，弟弟拍手赞成。顿时，他想变了一个人，一下子有了精神。经过半个小时的努力，弟弟不仅把课文读会了，而且还背会了呢！

通过这件事，我明白了：当老师是多么不容易，我们应该懂得老师的良苦用心，老师说什么，我们做什么，做一个听话的好孩子。

In general, there are two ways of traveling, private cars and public transportation. Chinese people should regard public transportation as their first traveling opinion.

一般来说,有两种旅游方式，私家车和公共交通工具。中国人应该把公共交通工具作为旅游的第一选择。

First, there are so many people living in this countries that make it so crowded. If each chinese people own a car, there will be far more traffic jams and accidents, which increase you impatience.

首先,这个国家住着很多人，使得它非常拥挤。如果每个中国人都拥有一辆私家车，将会有更多的交通堵塞和事故，这会让你变得更加的不耐烦。

Moreover, there will be far more pollution resulted from cars. Once a car started, it release huge amount of dirty gas and heat, which lead to great pollution and result in green house effect.

再者，由于私家车将会有更多的污染。一旦汽车起动,它释放大量的脏气和热量，这会导致很大的污染和温室效应。

All in all, Chinese people should take public transpotation into consideration first。

总之，中国人应该以公共交通工具为第一选择。

虽然人们现在都说要保护动物，但是还有很多人执迷不悟，继续猎杀动物，导致许多动物都走向了灭绝的道路。同时人类还拿动物来观赏、卖钱，用兽皮做大衣……但这些人有没有想过，如果你是一只动物，却遭到了人类的猎杀，你会怎么想?有些人说：“我又不是动物。”但是现在人类大量捕杀动物，动物会愿意吗?不，永远不会。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，猎杀动物，照样兴致勃勃的品尝动物鲜美的肉。就拿我们身边的小狗来说吧，虽然不是国家一二级别的珍贵动物，但也是我们身边的好伙伴，不管主人怎么使唤它，它仍然很兢兢业业，可是人类发现狗肉鲜美，就开始捕杀小狗。

现在，有些动物已经快要灭绝了，就拿鳄鱼来说吧，它虽然很凶猛，但人类更凶猛。而在人类的眼中，鳄鱼皮可以制成行李箱，手提包，钱包，鞋等物品。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。所以鳄鱼，现在已经成为快要灭绝的动物了。朋友们，动物的大量毁灭对人类将产生严重的不良后果，造成生态环境严重不平衡，从而使人类的生存环境遭到破坏。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!让我们从现在做起，保护动物，使世界变得更加美好吧!

I went to the gate of the primary school in shangjia city, and I was like walking into my other home, where I studied, lived, grew up, and my school was my home.

Lush trees, clean corridors, white walls. However, there are a few students on our campus who break the beautiful environment at will. The campus stairs and the various food packaging bags in the hallway, the various drink bottles of the flowers, the prunes in the classroom, the melon seed shells... The environment that makes us beautiful is destroyed, and it feels like a blank sheet of white paper. Taking care of the campus environment is the duty and responsibility of each of us.

So what can we do to make our campus environment civilized?

To set up the campus is the idea of home, the campus is my home, everyone loves it. Students should love the campus as much as they love their new clothes.

On the campus, the behavior should be standardized, from the little things, from a little bit, the daily behavior standard is every day, every time, everywhere.

We will comply with the regulations of the elementary school childrens daily behavior and strictly observe the institutions of the school. Be a good boy at home, be a good student at school, and be a civilized citizen in society.

4, do not break the environment of the school carelessly, should not throw waste to the ground; You shouldnt leave a mark or a handprint on a white wall. Consciously pick up every piece of paper or food bag on the floor; Stop unethical behavior.

To correct bad behavior, we cant just rely on our teachers and consciousness. Use concrete actions to protect and protect our campus environment. Start by myself, start by yourself, start every day, protect the campus environment.
