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。

在动物园看得到大象，我第一次亲眼看到大象时，觉得它的身体像一面大墙，象腿象四根大柱子，象鼻像一根大吸管，把食物通通送到嘴里;虽然庞大的身躯让人害怕，不过它的一举一动让我觉得很可爱!

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 aloneare considered in danger.

动物是自然资源，人们已经浪费了整个历史。动物已为他们的皮毛和羽毛，食物而被杀，运动，因为他们在路上。成千上万种动物已从地球上永远地消失了。今天，数百人在危险中。对170种美国aloneare危险。

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.

人为什么要在乎?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的。它们不仅仅是人类的食物来源。每一个动物在自然界的平衡有它的地方。毁灭某种动物会导致许多问题。例如，当农民杀死为数众多的鹰，他们谷物和粮食的商店被老鼠破坏。为什么?因为鹰吃鼠类，没有鹰控制它们的数量下降，鼠类就会迅速繁殖。

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.

幸运的是，有些人正在努力帮助拯救动物。有些组织筹钱以便让人们了解这一问题。他们试图让政府通过保护濒危动物的法律。很多国家已经通过了法律。这些法律禁止任何动物或杀害濒危名单。慢慢地，某些濒危动物的数目正在增长。

在我童年的回忆中，只养过一个小小的宠物，大家知道是什么吗?一只可爱的小乌龟!

小乌龟是我从市场上购买的，那个卖乌龟的阿姨告诉我，这种小乌龟永远长不大。听了阿姨的话，我对这只可爱的小乌龟更加的好奇了。

小乌龟有一个硬邦邦的壳儿，这可是它的“保护伞”哟!它的壳儿是翠绿色的，上面排满了六边形的团，下面也是由六边形的团组成的，只不过是乳白色的;小乌龟的头一旦有东西碰到了，酒会快速和两队足一起收回壳儿里，显得它特别小心谨慎。这只小乌龟很特被，头上有个菱形的小红点，特像个“小剑客”。小乌龟的眼睛水灵灵的、大大的，下面长着一张“樱桃小嘴”;再说说小乌龟的四肢。它虽然爬得很慢，但动作却很迅速，四肢很灵活;小乌龟有一根小瞧的尾巴，细得像根毛线。这根小尾巴平时伸出来时一摆一摆的可爱极了!

第一天把小乌龟买回来是它在小鱼缸里一动也不动的，我还以为它死了呢!过了一段时间，在我和外婆的精心照料下，小乌龟终于肯把头伸出来了，但有脚步声，它又把头和四肢都收回了它那硬邦邦的“保护伞”里。又过了一段时间;小乌龟终于和我像好朋友一样，非常开心。

小乌龟喜欢住在有水的地方(水不能太深)、喜欢吃颗粒较小的龟食、喜欢在平地上玩耍……

动物是人类的朋友，让我们亲近动物、关爱动物、保护动物，让我们从身边做起、从小事做起，让动物和人类成为真正的好朋友!

今天，小明在离家不远的大树旁玩耍。一只小鸟在树梢上一边悠闲地梳理着自己的羽毛，一边快乐地唱着歌，歌声委婉动听，突然，他发现一只小猫爬到树上想抓小鸟。小明想：小猫要抓小鸟，要伤害她，我该怎么办呢?他想了想，”对了!“他叫了起来：”小猫，小猫，快下来，不准伤害小鸟，她也是有生命的。“小猫好象听懂了小明的话，犹豫了一会，”嗖“的一声从树上跳下来，冲着小明”喵、喵“叫了几声，跑走了。

这时，小鸟扭过头，冲着小明”唧唧喳喳“，仿佛在说：”谢谢你，谢谢你。“小明仰起头，说：”不用客气，不用客气，这是我应该做的，保护动物，人人有责。“

周末，妈妈终于同意我看CCTV《纪录频道》了。我在电视上看到这样一则故事：动物濒临灭绝。那是在南平洋的岛国新西兰附近，当地人一直以打鱼为生。他们整天在南太平洋公海上疯狂打捞，致使那里很多鱼类濒临灭绝，由于环境变化，成千上万只信天翁来到这里安家。由于人类大肆捕捞鱼类，而以吃鱼为生的信天翁经常没有食物，它们成群结队的去和渔船上的渔夫争抢食物，渔夫有时在杀鱼的时候扔一些鱼内脏给它们充饥，然而，信天翁争抢食物会影响渔夫的工作，而且，扔给他们的东西并不是所有的都能吃，有时候渔夫还会在里面掺毒，更有甚者会直接射杀。虽然信天翁对这些了如指掌，但它们为了生存，还是会在海面上争抢一切食物。由于渔民的大肆捕杀和食物，全世界曾经有22种信天翁现在只剩下3种了。

如今，很多人已经认识到自然界中，人与动物应该和谐相处。南太平洋公海已被联合国划定为保护区，但还是有渔船在这片海域进行破坏性的捕捞，很多动物仍然濒临灭绝，让环保人士叫苦不迭。

我们有时要酒店里，能吃到一种类似粉丝的汤，这就是鱼翅汤。它是用鲨鱼的背鳍做成的。在美国，一碗鱼翅汤要卖几百元，很多有钱人认为吃鱼翅汤是一种地位的象征。有一部份渔民长年在海洋中捕杀鲨鱼，他们将鲨鱼捕到渔船上，残忍地割下鱼翅后，将鲨鱼扔进大海。由于被割去鱼翅的鲨鱼不能游动，它们就这样慢慢的死去。为了阻止这种捕杀，联合国派遣“绿色小队”到海洋中去寻察，而捕杀者们通过各种各样的方式逃避“绿色小队”的检查。有一次，检查人员登上一条渔船，船上有一个冷冻舱，里面有几十条死鲨鱼，但值钱的鱼翅并不在这里，而是被他们转移到其他地方藏起来，检查人员来到另一个冷冻舱，里面装着几十袋鱼翅，这已造成了百条鲨鱼的死亡，电视画面惨不忍睹。“绿色小队”立即废除了这艘渔船。

想起姚明做的广告，呼吁人们不要去吃鱼翅，它的营养和粉丝差不多。“没有消费就没有杀戮”。动物是我们的好朋友，我们人类也应该成为动物的好朋友，我们大家要爱护环境，保护动物，亲近自然，不要让动物离开我们。

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!

Few Americans study stay put for a lifetime. They move from town to city or to suburb, from high school to college in a different state, from a job in one region to a better job elsewhere, from the home where they raise their children to the home where they plan to live after retirement. With each move they are forever making new friends, who become part of their new life at that time.

很少有美国人学习留一辈子。他们从城市搬到城市或郊区，从高中到大学在不同的国家，从一个地区到一个更好的工作在其他地方，从他们的家中，他们的孩子在家里，他们计划在退休后生活。随着每一个移动，他们永远在新的朋友，谁成为他们的新生活的一部分，在那个时候。

今天下午的语文课，胡老师和平时一样的走进教室。他站在讲台上，腰挺得直直的，面带笑容，非常可爱。她的笑容犹如一朵刚刚绽开的花儿。她今天展现了另一面的胡珊。

首先，胡老师给我们大家念了一篇她自己写的文章，名字叫做《生命奇迹小狐狸》观后感。这部电影讲述了一个小男孩救了一只残疾的小狐狸，取名叫海伦。虽然小狐狸只活了6周多，但是，却和小男孩太一结下了深厚的“母子情”。她在念的过程中表情完全表现出了这部电影所表现出的感情。读完，我们大家的惊呆了，简直不敢相信胡老师写作文可以写到这个程度。有的同学情不自禁地说出：“真厉害”！有的同学被吓的连话都不敢说了，还有的同学听完就鼓起了掌，其中我们班上的曾阳浩同学还非常大声地说出：“好”！总之，大家都不相信这是真的，可是，就是胡老师认真写出来的呀！

念完，胡老师还告诉我们无论是什么生命，都要竭尽全力的活着它的生命时间。“没有买卖，就没有杀害！”我们没有权利去剥夺野生动物的生命，他们在为自己的生命而竭尽全力的活着，为第地球村的丰富多彩活着，那么多的爱护动物人士在努力着，我们普通人可以做的就是爱护身边的小动物，他们是人类的好朋友啊！没有了他们，我们地球就少了那么多欢笑；没有了他们，我们人类就少了那么多好朋友；没有了他们，我们人活在这个世界上就没有了意义。心怀善良，尊重生命！

在学校里，我的同学送了我一个小动物一一蜗牛，见到它的第一眼我就下定决心，要保护它，养好它。

蜗牛看上去好可爱！它的壳是螺旋形的，一直盯着看让人想睡觉。它的触角长长的，像两根天线，要把信息收集起来，上面有芝麻粒大小的圆球，是眼睛。我把它放在一个盒子里，铺一点草，把餐巾纸淋湿挤干，再放到盖子上，这样里面会很潮湿，因为蜗牛生活在阴暗潮湿的地方嘛。我观察着它，这是一个陌生的地方，蜗牛东看看西瞧瞧，东走走西走走，仿佛在不停地说："这是什么，这是什么，这是什么……”这样子好搞笑。它爬得很慢很慢，我一直盯着它，眼睛都发酸了。

后来因为学习太繁重，也没有怎么喂它。有一天，我发现蜗牛不动了，我等了一会儿，还是没出来。我想：你快出来阿，我的朋友！等不及了！我把壳拎出来，往里面瞧一瞧，蜗牛不见了，摇一摇，好像是空的。我马上跑去找叔叔：“叔叔，蜗牛不会死了吧？”我心急如焚。“没错，”叔叔端详着蜗牛说“它确实死了。”顿时我鼻子一酸，眼睛湿湿的，我哭了。我感觉心里有说不出的难受。不管妈妈怎么安慰我，我还是哭。

我明白了对小动物只有喜欢是不够的，还要耐心地照顾它们，妈妈说这就是爱和责任。

遥昀、以薰和周尼是三个非常友好的朋友，他们每天下午放学都到学校图书馆里看书、借阅。

这天，以薰来到图书馆，可却没有看到遥昀和周尼。她等了大约有半个小时，见他俩还没来，就准备先回家了。以薰在图书馆里借了几本书，就自个先回家了。以薰出了图书馆的门，看见遥昀和周尼把种在柱子旁的大榕树上的鸟窝拿了下来，就赶忙跑了过去。“喂!你们俩个干什么呢?我已经在图书馆等你们俩个快半个小时了，你们怎么回事呀，是不是干了些见不得人的事呀?”以薰生气的说。“才没有呢，我们只是随便玩玩嘛!”

遥昀慢吞吞的咕嘀着。“让我看看你们都干了什么好事!”以薰看了看周尼手上的小燕子。急匆匆的说：“哎呀!你们怎么能捉小燕子呢，你们知不知道小燕子的妈妈会多着急呀，假如每个人都像你们这样做、这样想，那这个蔚蓝色的天空就再也没有飞禽的踪影了呀!”没等以薰说完话，以薰就两手牵着周尼和遥昀的手，飞快的跑到了教学楼，带他们来到了自然科的动物标本室。以薰用拾指着燕子的自然标本雕塑。对遥昀和周尼说：“你们俩个看看上面的‘动物指南’上面写着什么要自己看，你们也不想想啊，一年有几个季节呀，才四个呢。小燕子只有冬天才到我们南方这来冬眠。你们说假如是刚出生的小燕子，第一次来，看到你们这样破坏它，它们以后就不会来的。再说，它们要是不来这儿冬眠，那它们要到那里呢?可是它们要是不来，它们就会在北方冻死的。难道你们就希望它们在北方给冻死吗?你们也对它们太残忍了吧!”

以薰说着说着就没有力气了。遥昀和周尼脸也已经变得红彤彤的了，同时也觉得自己很丢脸了。他俩一时也说不出话来。以薰见他俩没反应。又大声说了一句：“知道错了还不行动呀!”说完后便推着他们来到了刚才那棵大榕树下。

他们三个找来一个梯子，以薰自告奋勇说要自己爬上去，要亲自把小燕子和窝拿回大榕树上。那遥昀和周尼呢，他们啊，也一个劲的在下面欢呼。看着小燕子这时的“欢乐心情”他们三个心里默默的想——爱护动物应该从我、从小做起。

一天傍晚，小明和哥哥走在放学回家的路上，走着走着，突然“啪”的一声，小明和哥哥仔细一看，原来是一只小鸟。小明说：“呀!小鸟受伤了，我们给它包扎好了伤口，再把它放回鸟巢吧!”哥哥说：“行!我给它包扎。”

哥哥给小鸟包扎完了伤口，小明和哥哥不知道鸟巢在哪里?突然有小鸟的叫声仿佛在说：“我的孩子呢?”哥哥抬头一看有两只小鸟在树上急得团团转，小明说：“这一定是小鸟的爸爸妈妈，我们赶紧把小鸟放回鸟巢里，让它们一家团聚吧!”哥哥说：“这树太高了，我放不上去呀!”他俩想了好一会儿才想出一个好办法。

小明骑在哥哥肩上把鸟放回鸟巢，哥哥紧紧的抓住弟弟的脚，生怕他掉下来。弟弟轻轻地把小鸟放回鸟窝，放完他们悄悄地走了，小鸟的爸爸和妈妈飞在天空“唧唧喳喳的仿佛在说：”谢谢你们，帮我找回了孩子。“小明和哥哥一起说：”不用谢!保护小鸟是我们应该做的。“小明和哥哥多么爱护小动物呀!

The snake is a long and thin animal that lives in grass or other dark places.A snake has no legs or feet,but it can move very fast on its stomach.Snakes usually have green,yellow or black skins,which make them difficult for their enemies to find them.Some kinds of snakes live in water.They can swim as freely as fish.

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.

今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，大家都非常喜欢它们。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，就应该爱护它们。”他的脸红了，并且回答说他不会再那么做了。

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。
