如何写保护动物的英语作文实用20篇

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!

以前，在大森林里，白天有鸟儿们在高声歌唱，蝴蝶在旁边翩翩起舞。夜晚，萤火虫把森林照得光亮，蛐蛐在草丛吱吱的叫着。如今，我们还能看到这样的美景吗？

在草原，森林里，有许许多多的动物已经走向了灭绝之路，还有的动物在灭绝的边缘徘徊着。例如：欧洲大象、孟加拉虎、穿山甲、沙猫……人们在这个社会上已经被金钱迷惑了双眼。把象牙做成各种各样的雕刻品，把动物的皮毛做成衣服，把鹿的角做成药品等等。加上人类把树木都给砍光了，让动物无家可归。

有一次，我在看书的时候发现了一条信息：以前，长臂猿喜欢在树林里边爬树，边大吼，发出很多的叫声，让人听了震耳欲聋。于是猎人们借助这个特点，把长臂猿给大量猎杀。因此，长臂猿在森林再也不敢乱叫了，有的甚至不发出声音了。

也许有的人会问：动物不是繁殖能力很强吗？一胎就能生出四、五只。

动物虽然多；但是并不是所有的都能活下去，有些动物不但要解决温饱问题，还被天敌追杀。人类又乱改乱锯把树木都砍光了，结果引发了洪水，造成了一系列自然灾难。

在此，我呼吁：人类快清醒吧，不要被金钱给迷惑了。

Environment is a basic human existence conditions, if we destroy the environment, it is ruined our survival conditions.

At present, the ecological environment is becoming more and more bad, is the greatest influence on our water resources. According to the relevant information reported: the laying of drainage system and detergent used to grow, consume the oxygen in the water, fish died, deterioration of ecosystem. Human activities can make a lot of industrial and agricultural pollutants into the water, the water is polluted. The world each year about 4200 sewage into the river, polluting the 5. 5 trillion of fresh water.

This is how the startling fact, protect the environment is everyone duty, why want to destroy?

Lies a small river near my grandmas home, on the bottom, before my sister and brother in ones childhood often swimming in the river, and their friends to play in the water, uncles and aunts are often in the river to wash clothes, wash dishes, and now, near the river built a chemical plant, the production of waste water discharge into the river, originally the bottom stream gradually turned into a black sending out the smell of the river. The adults never go to the river to wash clothes to wash the dishes, friends never go to the river to play, too!

How I miss the crystal-clear stream! I think: cherish resources, good care environment, these are GongZaiDangDai, force and art event! If we are in such polluted water, that we can use water resources will be less and less, we destroy the environment, is destroying our living conditions.

Let us join hands to jointly protect the environment, dont let water into water, protect the environment, is our common responsibility!

环境是一个人类生存最基本的条件，如果我们破坏了环境，这等于破坏了我们生存的条件。

目前，生态环境日益恶劣，对我们影响最大的就是水资源。据有关资料报道：排水系统的铺设和清洁剂的使用有增无减，消耗水中的氧，使鱼类死亡，生态系统恶化。人类的活动会使大量的工业、农业污染物排入水中，使水受到污染。全世界每年约有4200多亿的污水排入河中，污染了5。5万亿的淡水。

这是多么让人触目惊心的事实啊，保护环境是人人有责的，为什么要破坏呢?

我外婆家附近有一条小河，以前清澈见底，我的姐姐、哥哥小时候常常在小河里游泳，和他们的小伙伴们在水中嬉戏，叔叔、阿姨们也常常在这小河中洗衣服、洗菜，而如今，小河旁建造了一个化工厂，把生产的废水排放到河里，原本那清澈见底的小河渐渐变成了黑黑的散发着怪味的小河。大人们再也不去小河洗衣服洗菜了，小伙伴们也再也不去河里嬉戏!

我多么怀念那条清澈见底的小河啊!我想：珍惜资源，爱护环境，这些都是功在当代、力及千秋的大事啊!如果我们在这样污染水，那我们可以用的水资源就会越来越少，我们破坏环境，就是破坏我们生存的条件。

让我们携起手来，共同保护环境，不要让淡水变成污水，保护环境，是我们共同的责任!

一天，小明走在安静的小路上，突然，他看见草丛里有什么东西。

小明走到草丛前，一看。啊!原来是一只小鸟受伤了。小明心想：这只小鸟好可怜，我还是带小鸟回自己家，给它包扎一下。他手忙脚乱地跑回家。拿起药箱，小心翼翼、轻手轻脚得给小鸟包扎起来了。小明费了九牛二虎之力才把小鸟地伤包扎完了。小明就把小鸟放在一个篮子里。还要每天喂它谷粒吃，真的好辛苦啊!过了几天，小鸟的伤完全康复了。小明就把小鸟放回了美丽的大森林里去了。小明又能看见小鸟在天空中翱翔。心想：我又做了一件保护动物的事情。小鸟也心想：人类是我们的好朋友。

My favorite animal is the rabbit.

Little rabbit has a pair of long ears, shaft above the head, the alert around listening to movement, ruby eyes going round and round. Two big die like corn, nibbling at things very convenient, to a furry white creature, if four feet and head up, just like a white cotton ball. Little rabbit moves very fast, there is a phrase "quiet as a pussy, move as tuotu" is to describe it.

Today, my family have a new guest, it is little rabbit. I live in a cage, let it give it a green vegetables to eat, and his eyes glow, immediately 烔 烔, two large die in their ears at the green trend, less than a few minutes, green vegetables was gone. It to to me sitting in a cage, eager eyes, as if to say: "give me something to eat, master!" I immediately threw a carrots to eat, not to a few minutes, carrot disappeared again, this time, it can be satisfied, lying in a cage, motionless, as if asleep, but I walked over, it wakes up, as if to say: "master, master, you take me go out to play, Im bored!"

Little rabbit to my house to add a few minutes of fun, I like it very much. I wish: everybody CARES for animals, because animals are humans good friends.

我最喜欢的动物是小兔子。

小兔子有一对长长的耳朵，竖在脑袋上面，警觉的听着周围的动静，红宝石似的眼睛滴溜溜乱转。两个玉米似的大板牙，啃起东西来非常方便，一身白茸茸的毛，如果把头和四只脚缩起来，就像一个白白的绵球一样。小兔子的动作非常快，有个成语“静如处子，动如脱兔”就是形容它的。

今天，我家来了一位新客人，它就是----小兔子。我让它住在一个笼子里面，给它青菜吃，它眼睛立刻发光， 烔烔有神，两个大板牙以迅雷不及掩耳之势向青菜扑过去，不到几分钟，青菜就不见了。它坐在笼子里，向我投来渴望的眼神，好像在说：“再给我一点东西吃吧，主人!”我立马投了一个胡萝卜给它吃，没到几分钟，胡萝卜又不见了，这回它可吃饱了，躺在笼子里，一动不动的，好像在睡觉，但我走过去，它又醒来了，好像在说：“主人，主人，你带我出去玩吧，我很无聊耶!”

小兔子给我家添加几分乐趣，我非常喜欢它。我真希望：每个人都关心爱护动物，因为动物是人类的好朋友。

From this cartoon, we can see that at the top end of the river,is a chemical factory and a paperrnaking factory which send out and poisonous wastes. And the river has been seriously polluted,n be seen from the color of it. Along this "black" river, there area few people selling fresh water which must have been taken from far away places.

At the first glance, it is very strange to us how can people sell water along the river, but this is the case, because the water in this river is undrinkable. This presents a serious social problem--environmental pollution. With the development of economy, our living standards have been greatly improved. But we can＇ t ignore the fact the air we take in and the water we drink today are not as fresh and clean as they used to be. Some kinds of pollution can even be deadly to people. It is high time that we took some measures to solve the problem.

I think we can first call people＇s attention to this problem so that they will be aware of the serious consequences of it. Then,we can pass certain laws to restrain the factories from sending out wastes. Finally, we can do more resarch work to find out ways to deal with the wastes.

Keep Square Clean, Tidy On Sunday, still on display on Tian＇anmen Square were dozens of floats that were paraded along Chang＇ an Avenue during the NationalDay celebrations. Thousands of people strolled on the narrow lanes be- tween the floats that fragmented the square, busily taking photos. Not far from the noisy crowds, yellow leaves fell nonchalantly from locust trees along the driveway, sending out the first signals of the coming autumn. But even if all the leaves fall, they still cannot cover the brown and black spots on the hitish stones in the huge square.

Such stains of chewing gum, stale oil or some worse blemish have remained a constant pain for city cleaners since the square ＇was re-opened a few months ago after renovations to celebrate the 50th anniversary of the founding of the People＇s Republic of China.

Few renovation project planners likely foresee this discouraging outcome. Originally, they merely intended to give the city a facelift. The square was indeed impeccable when new: The-white terrazzo surface not only looks clean but it was made with materials that help prevent it from becoming slippery.

However, as time goes by, the virtue becomes the vice: the surface attracts and accentuates dirt. As a result, China＇ s most high profile site has to suffer the indignity of being paraded daily efore thepublic in a humiliation state.

While the tourists who litter should bear the bulk of the blame, the renovation designers should also have learned something: including the square＇s sanitary maintenance issue into their consideration.

[关于保护环境的英语作文优秀范本

一天，天气晴朗，我吃完早饭，就拿着一个渔网和一个瓶子高高兴兴地去小河边玩。

我看到了小河里有一群群可爱的小蝌蚪，像许多小逗号一样，在水里快活的游了起来游去。我心想：“如果把小蝌蚪捞起来，拿回家，就可以每天玩了”。于是我一下子捞住了几只小蝌蚪，装进瓶子里，高高兴兴地跑回家。

晚上，吃过晚饭，我就坐在沙发上听收音机，收音机里边说了一句话：“保护动物，人人有责”。于是我赶快拿出“动物百科全书”来看，原来青蛙是益虫。

第二天，我拿着瓶子跑到河边把小蝌蚪放了，它好像在说：“小朋友，谢谢你，我一定快快长大变成青蛙，消灭害虫”。

小朋友们，以后我们都要爱护小青蛙，因为它们能吃许多的害虫，保护庄稼，是我们人类的好朋友。

说到大熊猫，大家一定都很熟悉，因为它是我们国家的国宝。但是说到它的习性，大家就不一定都知道了。下面，我就给大家讲一讲大熊猫的生活习性。 大熊猫胖乎乎、毛茸茸，满是白毛的脸上带着两个黑眼圈，憨态可掬。

大熊猫性情温顺，一般不会主动攻击其它动物。遇到危险时，大熊猫也没什么方法保护自己，只能赶快逃跑。逃不掉的话，它就会像害羞一样，用前爪蒙住脸，希望敌人看不到自己。 大熊猫天生喜欢吃竹子，鲜嫩多汁的竹笋更是它的美味佳肴。吃东西的时候，大熊猫会想人一样坐在地上，用有力的牙齿把食物咬碎。吃饱了还要喝水。大熊猫喝水可不像小猫一样舔舔了事，它经常一喝再喝，一直喝到走不动为止，然后就干脆倒在小溪旁睡觉，醒了还能继续喝呢! 大熊猫每胎2至3个，刚出生的熊猫宝宝非常小，只有妈妈体重的千分之一。两岁时，小熊猫才能离开家独立生活。

怎么样，听完了我的介绍。你们是不是对大熊猫有了更深的了解了呢。最后我们一起呼吁：“保护大熊猫，让它们永远和我们在一起!”

As we all know , animals are mans friends.Nowadays with the development of industry ,a lot of animals are in danger of extinction. We should protect animals so that we can live in a better environment .To protect them ,our government should forbid people to kill them , and for most of us ,we can plant more trees and call for protecting anmimals habitats.Only if we protect animals well can we have a bright future!

同学们、老师们：

亲爱的全体同学：

野生动物是人类的朋友，是自然生态系统的重要组成部分，是大自然赋予人类的宝贵自然资源。保护野生动物，维护自然生态平衡，不仅关系到人类的生存与发展，也是衡量一个国家、一个民族、一个地区文明进步的重要标志。

我国是一个野生动物资源非常丰富的国家，但是由于生态环境的恶化，野生动物栖息地的人为破坏，致使我国野生动物的数量，分布范围正日益缩小，许多种类已处于濒临灭绝的状态。近几年，滥食野生动物的现象屡禁不止，使得许多已经处于濒临灭绝的野生动物的处境更加艰难。最近，有记者采访调查表明:很多地方滥食野生动物的现象还十分严重，滥食野生动物的行为也正受到越来越多人们的谴责，要彻底改变滥食野生动物这种不文明的行为，需要社会各界的共同努力。

为此，我们倡议:加大《中华人民共和国野生动物保护法》的普法力度，媒体和社会各有关部门，要进一步加强对保护野生动物的普法宣传教育工作，使《野生动物保护法》的宣传家喻户晓，深入人心。

我们倡议:保护野生动物是全社会共同的责任，林业、工商、卫生检疫、公安、交通等有关部门认真履行职责，相互配合。坚决打击非法盗猎、非法运输、非法经营野生动物的违法行为，全社会也要积极行动起来，举报并协助执法部门，坚决与各种破坏野生动物的违法行为作斗争。

我们倡议:为了保护生态环境、为了保护野生动物资源、为了我们的身心健康，不食野生动物，树立饮食新观念，摒弃不良饮食陋习，保护野生动物从餐桌做起。争做文明、守法、有爱心的公民。

朋友们，为了人类共同的生存环境，让我们共同努力，一起行动起来，从我做起，从小事做起，让大地处处充满生命的绿色，让野生动物与我们在同一片蓝天下平安地生活。

让我们携手共创21世纪人类与野生动物和谐共存的美好家园!

Walk in the nature, can see the plants, in the park, in the grass, in the field, on the mountain... Plants everywhere, they accompany us, raising us. Plants and peoples relationship is very close, human beings can not be separated from them, their role can be large! Every day we eat cereal, barley is gone, sorghum shell, processed into corn. Such as we eat rice is rice to the skins, and heart everyday cannot little, vegetables, fruits and other plants into the?!

We drink, tomato juice, coconut juice, etc.. Dont look down upon the plants, you see! We wear clothes, but also depend on it, the clothes are made of cotton woven into cloth, usually cover the quilt, bed sheets, are derived from plants. When the festival, people always buy some flowers and bonsai decorative home. In addition, trees can also carry out photosynthesis, absorb carbon dioxide, release oxygen, bring us fresh air, trees can prevent noise. Plants are widely distributed in the vast sea, in the scorching sun of the desert, but with the environmental pollution, the survival of plants has been a great threat, some plants have been extinct. The relationship between plants and people is very close, we have to protect the environment, to create a better world for plants, so that they can grow.

让我们走进动物王国，倾听动物们发自内心的呐喊――(50年前)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!

人类是生存在这个地球上的生命物种之一，我们在爱自己同类的同时，也应该尊重其他生命，善意对待和爱护我们身边的小动物。

动物是人类的朋友，是自然生态系统的重要组成部分，是大自然赋予人类的宝贵自然资源。我国是一个动物资源非常丰富的国家，但是由于生态环境的恶化、动物栖息地的人为破坏，致使我国动物的数量、分布范围正日益缩小，许多种类已处于濒临灭绝的状态。

“砰砰砰！”枪声在森林中回荡，惊吓得鸟儿们慌不择路，四处飞散。

刚才打鸟的就是我的爸爸。

他十分喜欢拿着猎枪打来打去。只因为从小他就跟着我的爷爷在山林中狩猎，所以到现在他依然喜欢用猎枪打鸟、打野兔。每个周末，他都会带着朋友一起去小山林里打猎。就是在平时，他总拿着弹弓左射右射，打健力宝罐、打小鸟。

慢慢地，我长大了，在学校学到的知识多了，知道打猎的行为是错误的，我为爸爸的行为感到羞愧和可耻。

怎么才能制止他呢？

今天早晨，爸爸又准备去打鸟了。

“不要再打鸟和野兔了！”我大声地劝阻爸爸：“人和动物应该和平相处。”

爸爸愣在了门口，一言不发。

我振振有词地继续说道：“世界上有很多鸟类已经灭绝，如果每一个人都为了钱和自己的打猎爱好，那世界上的动物都会灭绝的。动物灭绝了，人类一样得灭绝！”

爸爸把门拉上，把枪放回了柜子里。

我拿出一本关于保护动物的书，这是我早准备好的。书上一张张鲜血淋漓的图片，控诉着人类的暴行。我把它递给了爸爸。爸爸眉头皱了皱，表情僵硬了。

他翻看着书，慢慢地走到客厅，坐在了沙发上。

“是呀，要给孩子做榜样。”妈妈语重心长地说，“打鸟的行为，破坏了大自然的生物链。大自然的生态不平衡了，最终必然会影响到咱们人类。”

“是啊，书上说保护动物就是保护我们自己。”我义正辞严地说着，眼睛看着爸爸的脸。

爸爸惭愧地低下了头，叹了一口气，说道：“我再也不打鸟了。走，儿子，咱们一家三口骑自行车去公园看天鹅去！”

保护动物，就是保护我们自己。保护一个个可爱的动物，从我做起！

导语：现如今环境污染越来越严重，我们应该保护环境!下面是yuwenmi小编为大家整理的相关英语作文，欢迎阅读与借鉴，谢谢!

Many people are active in fighting against unfair treatment to colored people, women , animals and so on. Right now I am talking about fighting for respect to our environment. Though the environment doesn’t have a mouth to deprecate what humans have done to her, she retaliates through action. In the early years the Chinese cut down large quantities of trees, at the source of the yellow river, which led to the disappearance of big forests and terrible floods. As a result，the Huangtu plateau which was once covered with grass and forests was turned into barrens that supported fewer plants. Another example was in several developed countries. Because many chemical factories discharged poisonous gas without filtering it, cities were covered with so much poisonous gas that people were killed by the air they breathed in. What horrible scene!

What we are suffering is only a small part of what the nature once suffered. If we don’t take action to show respect to the environment, we will have to face an increasingly awful situation.

Measures should be taken to protect the environment on which we are relying. First governments should forbid destroying vegetation, rivers and lakes, oceans, as and the atmosphere as well. Second voices should be made to announce the public of the importance of protecting the environment. Third enterprises should pay special attention to the effect they have on the environment and work out solutions for the problems.

Only by changing the way we treat the environment can we get along well with it. Only by saving the environment can we save ourselves.

【参考翻译】

很多人都活跃在对抗不公平待遇有色人种、妇女、动物等。现在我谈论要争取尊重我们的环境。尽管环境没有嘴巴来反对人类对她所做的一切，她通过行动来报复。在早些年中国人在黄河的源头大量砍伐树木，导致了大森林的消失和可怕的洪水。结果，曾经一度覆盖草地和森林的黄土高原变成了植物稀少的荒漠。另一个例子是在一些发达国家。因为许多化学工厂没有过滤就排放有毒气体，城市充满了如此多的有毒气体，人们通过呼吸这些空气收到伤害。这是多么可怕的场景!

我们所痛苦的是只有一小部分的自然曾经收到破坏。如果我们不采取行动，尊重环境，我们将不得不面对一个日益糟糕的情形。

保护环境应采取我们依赖的措施。首先政府应该禁止污染植被、河流和湖泊、海洋和大气。第二，应该宣布公众保护环境的重要性。第三，企业应特别注意对环境的影响和解决方案的问题。

只有通过改变我们对待环境的方式，我们才可以相处得很好。只有拯救环境，我们才能拯救我们自己。

Last Sunday my father and I went fishing along a river. We found the water so dirty that we could hardly catch fish in it.

A lot of factories along the river always poured their waste water and rubbish straight into the river which made the river water polluted. In this way most of the fish in the river were killed.

If the river water all over the country is polluted like this， no living things will exist in the water. As we all know， environmental pollution does great harm to living things and human beings. Now more and more people have come to realize how serious this problem is. Our government is doing her best to take measures to fight against pollution. We expect that the water in every river will be made cleaner and cleaner before long.

上个星期日我和爸爸一起去钓鱼。我们发现水太脏了，我们几乎不能在它的鱼。

沿着这条河的许多工厂总是把废水和垃圾倒进河里，使河水受到污染。这样，河里的大部分鱼都被杀死了。

如果这个国家的河水都被污染了，水里就不存在生物。我们都知道，环境污染对生物和人类都有很大的危害。现在越来越多的人开始意识到这个问题有多严重。我国政府正在尽最大努力采取措施打击污染。我们期望在每一条河流中的水将在长时间内变得更清洁，更清洁。

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。

Our modern city is too crowded， and to solve the problem， three proposals are put forward. Most people believe that we should fist practise the policy “Late Marriage” and “One Couple， One Child” in order to reduce the birth rate. Secondly， the city government must have a tight control over rural people entering cities to engage themselves in trade or do various physical jobs so as to lessen the pressure on the city caused by the increased population. Finally more and more people suggest that living blocks with shopping centers， schools， hospitals as well as cinemas and theatres round them or even satellite towns should be built in city suburbs or the countryside round the cities. In this way city citizens will be encouraged to move there to live and work. If these three proposals are well carried out， the city population will be greatly reduced.

我们现代城市太拥挤了，要解决这个问题，提出了三点建议。大多数人认为我们应该在政策上“迟婚”和“一对一”，以降低出生率。其次，城市政府必须严格控制农村人口进入城市，从事贸易或从事各种体力劳动，减少人口增长造成的压力。最后，越来越多的人建议，居住在购物中心、学校、医院、电影院、剧院等生活街区，城市郊区或郊区的城市应该建在城市郊区或城市周边的城市。在这个方式中，城市居民将被鼓励在那里生活和工作。如果这三项建议都很好地实施，城市人口将大大减少。

星期五放学后，我和妈妈去公园散步。

After school on Friday, my mother and I went for a walk in the park.

公园里的花散发着淡淡的清香，小草从地下钻出来了，柳树摇着绿色的长辫子。但是我发现有人带着小狗在草地上跑着，有的小狗在草地上随地大小便，草地就搞得很脏，小狗的粪便污染了公园的环境。

The flowers in the park exudes a touch of fragrance, the grass from the underground drilling, willow shook his green long braids. But I found someone with a dog run on the grass, some of the dog in the grass on the grassland is defecate, get dirty, dog feces pollution of the environment of the park.

我想我们每一个去公园的人都应该管号小动物，不要随意污染环境，这样我们的地球才会更加美丽。

I think every one of us went to the park to the people should be small animal, do not pollute the environment freely, so that our earth will be more beautiful.

全县父老乡亲、朋友们：

野生动物是人类的朋友，是自然生态系统的重要组成部分，是大自然赋予人类的宝贵自然资源。我国是一个野生动物资源丰富的国家，但是近些年来由于生态环境的恶化、野生动物栖息地的人为破坏，致使我国野生动物的数量、分布范围正日益缩小，许多种类已处于濒临灭绝状态。自从地球上有了人类，我们的命运就与野生动物息息相关，动物作为生物链的重要组成部分，却面临着前所未有的危机。全世界每天都有珍稀动物在灭绝，每天都有成千上万的动物被猎杀。大自然的生态平衡被破坏，益虫被杀，害虫猖獗，森林被伐，灾害频繁;植被破坏，土地沙化......我们的自然生存环境正在恶化，可是我们又能怨谁呢?这难道不是我们这些大自然的主宰者，猎杀动物、砍伐森林、摧毁植物造成的吗?这难道不是我们在自己毁坏生存环境吗?据调查表明，近几年我县城乡餐馆、酒店非法经营野生动物的现象屡禁不止，使得许多已经处于濒临灭绝的野生动物的处境更加艰难。为了保护共同的生态环境，为了保护野生动物资源，为此，我们倡议：

一、从我做起，保护野生动物从餐桌做起，不滥食野生动物，禁止食用野鸭、天鹅，树立饮食文明新风尚;不滥捕、不猎杀野生动物，做文明、守法、有爱心的好公民。

二、关爱动物，保护森林，让茂密的森林成为野生动物的栖息庇护场所。

三、各饲养、运输和餐饮企业不非法经营、贩运、加工、制作、销售野生动物及其制品，做绿色、环保、守法的经营者。

四、人人行动起来，积极劝说阻止、举报各类破坏森林、伤害野生动物的行为，做保护生态环境的模范。

朋友们，为了人类共同的生存环境，为了让汉寿成为更加美好的家园，让我们共同努力，一起行动起来，从我做起，从小事做起;让大地处处充满生命的绿色;让野生动物与我们在同一片蓝天下平安地生活。
