From the passage we know that thousands of endangered animals are facing the threat of being bought and sold on the internet. Traders make a great profit from it，which is illegal.

As is often read in the newspaper reports， wild life especially the rare species are threatened with extinction. Human beings are making attempts to hunt wild animals for a big profit， which， of course， results in a sharp decrease in the number of animals.

Therefore， it is high time for us to take quick action to protect them. First of all， it’s quite necessary for every citizen to realize the importance of animal protection. Only by knowing its importance can people develop a sense of responsibility. In addition， the government should pass some laws to forbid any hunting of rare animals.

If I were one of the endangered animals， I would hope that man could be a good friend of mine rather than my enemy.

从文中我们知道成千上万的濒危动物面临的威胁是在网上买卖。交易员有很大的利润,这是非法的。

经常在报纸上看到报道,野生动物尤其是稀有物种濒临灭绝。人类正在试图猎杀野生动物,也赚了不少钱,,当然,导致动物的数量急剧减少。

因此,是时候为我们迅速采取行动来保护他们。首先,它是非常必要的对于每一个公民意识到保护动物的重要性。只有通过了解它的重要性人们可以开发一种责任感。此外,政府应该通过一些法律来禁止任何捕猎珍稀动物。

如果我是濒危动物之一,我希望那个人可能是我的一个好朋友而不是我的敌人。

Panda is our country’s treasure, we should protect it. nowadays, we see from the TV that panda is less than before, it is not only because of the damage of the environment, but also the weakness of the panda.

So called for everybody, please protect the animals, wild animals less and less now let our home full of vitality!

地球上一片生机勃勃，到处都是可爱的生命。生命需要我们去珍惜，我们去保护。

人有生命，动物也有生命。

公元前出现了猿人，对于现在，有些人认为，他们只是会群居的动物。其实，说这话的人，也就是他们演变而成的。

从古至今，许多人曾不择手段的捕杀动物。就拿以前的广东人来说吧，他们最喜欢生吃野生猴脑了，那时，他们把活生生的猴子的头盖骨去掉也不觉得残忍。可怜了那些猴儿啊……

现在，在动物园里，我们往往会看见“请不要喂食”的标语。就是为了让旅客们别投搞恶作剧。一次，一只动物就是吃了旅客投的塑料袋，生病了。

所以，呼吁大家，请保护动物，现在野生动物越来越少了让我们的家充满生机吧!

因为，有很多昆虫都对人类有益。比如说：蜜蜂，它很勤劳，每天早上很早就出去采蜜，一次又一次。到了天黑，吃几口蜜糖后，就马不停蹄地对采来的蜜进行加工。蜜蜂的外形并不起眼，生命也很短暂，只有3个月左右；可它一生都不休息，勤勤恳恳地工作，它们对人类毫无所求，却为人们酿造了甘甜可口、营养丰富、可医治病痛的蜂蜜。

还有青蛙，青蛙披着碧绿的衣裳，两只大眼睛，像两颗晶莹透明的玻璃球，它藏在田里，专吃害虫，保护庄稼。它捉害虫的时候两条后腿一蹬，一纵身，敏捷地将后腿一蜷，跳起老高，长长的舌头一伸，就像一个吸尘器一样转眼就把害虫吃到肚子里去了

可是，我们人类却把它们当成美味佳肴摆在餐桌上。

还有许多可爱的动物，我最喜欢的是大熊猫。大熊猫是我国珍贵的动物，妈妈告诉我大熊猫还是我们国家的国宝呢！大熊猫长的很可爱，胖乎乎、圆滚滚的，走起路来一摇一晃的，特别逗人。它的头部和身体都是白色的，只有眼圈、耳朵和肩部是黑褐色的。特别是那一对黑黑的眼圈，长在白白的脸上，像是戴着一副墨镜，加上那笨拙的动作和走起路来东张西望的神情，显得像个小绅士。

你瞧！它们多么可爱，它们是我们人类的好朋友，我们怎么忍心伤害它们呢！

现在这些年已经有很多关于保护环境的问题。其中最严重的一个问题就是温室气体排放已经造成了气候改变。同时，很多树木被砍伐掉了，而且大量别的资源已经被用完或者浪费。所以我们的地球变得越来越温暖(热)。这样带给我们的是疾病和死亡。。

幸运的是，很多国家已经采取了很多措施来控制环境污染问题。如今，这是最重要保护环境的措施。

我认为，一方面，虽然教育我们应该让人们意识到破坏环境就是伤害人类自己。另一方面，我们应该尽力做一些事情来控制温室气体增长。

总之，我们必须发展低碳经济。

谁能告诉我哪里是我的家？谁能告诉我哪里有我自由的天空？谁能告诉我我的父母在哪里？谁能告诉我……

我叫咪咪，原来有一个幸福的家庭，家中有爸爸妈妈的疼爱。每当晨光熹微，我在伙伴的呼唤声中苏醒，伙伴们在林间嬉戏着。妈妈早已为我准备好丰盛的早餐，快乐的一天就从这里开始……暮色降临，爸爸在一旁给我讲闲暇的故事，林子里的一切都那样安谧。那时我们在这林子里生活得多么幸福呀！

可是好景不长，有一天来了一群猎人，他们拿着猎枪四处寻找猎物，我的同胞有好多已经被他们打死了，爸爸说它们都被卖到大酒店里去做特色菜——“小鸟点盘”。我担心地问爸爸、妈妈：“我们是不是也要遭受这样的厄运呢？”妈妈从容地：说：“孩子别怕，有我们在。”但从他们不安的眼神中，我感到了恐惧的来临。惊魂的枪声时常打破了树林的宁静，伙伴们的呼唤声越来越少，爸爸、妈妈常常护着我躲在窝中不敢轻易地行动。

这样提心吊胆过了几天，灾难终于降临到我的家中。爸爸为了保护我，让我骑在他的背上，带我飞走。而妈妈却留下来引开猎人，临行前，爸爸叫妈妈小心一点，在一片告别声中猎人的枪声已经响起，爸爸只好带着我一步三回头地飞走了。在一阵枪响之后，我的妈妈被打死了。我大喊一声：“妈妈……”猎人发现了我和爸爸便向我们举起了枪。爸爸躲开了猎人的子弹，带我向一片森林飞去，猎人依然穷追不舍。爸爸将我安置在茂密的丛林中，自己去跟猎人搏斗。我的直觉告诉我，爸爸这一去就回不来了。果然，一阵枪响和惨叫之后，我的爸爸死了。

从那以后，我饱偿了没有母爱、父爱的痛苦，虽然猎人走了，我的生活并没有变好。过了几年，又有一群人把这片森林砍伐了，我已经没有地方安家了，只能四处盘旋，流浪。

人类快快醒悟吧！不要再伤害野生动物了。地球是我们赖以生存的家园，给我们一点生存的空间吧！不要因为你们的贪婪而破坏我们幸福的生活！这是一只小鸟在呼吁，这是一只小鸟在哭诉！

How to protect our environment has become one of the biggest problems in the world. We do everything can do a real difference to our environment.

We need to pick up litter around us. Youd better join a programme to protect our environment. You mustnt cut down too many trees. We can protect factories from polluting the rivers.

那天，我妈妈给我买了两只小鸭子。我很高兴，把两只小鸭子放在箱子里，听着它们的叫声，我的心情非常的好。

That day, my mother bought me two little ducks. I am very happy, the two little ducks on the box, listening to their voices, I feel very good.

第二天，我想让同学到我家看看我的鸭子，我给同学打电话，让他来。他看了鸭子，也觉得很好玩。我们把一只小鸭子放在地上，它向前走了几步就摔倒了，它抓了起来，又摔倒了，我们哈哈大笑。我们玩够了，就把小鸭子扔进了箱子里，去玩玩具了。

The second day, I want to have a look to my classmates my duck, I call for students, let him come. He saw a duck, and enjoy it. We put a duck on the ground, it went forward a few steps and then fell, it caught up, and fell down, and we laughed. We play enough, put the duck into the box, to play with toys.

下午，我和爸爸去看小鸭子，看见一只鸭子肚子朝上，翅膀和脚在抖动，它叫的声音很大，好像在哭一样。爸爸把小鸭子扶起来，小鸭子又倒了。我突然想起来我把小鸭子扔进箱子里的事，呀!我是杀人凶手呀!我哭了。小鸭子最后死了，我很伤心。

Afternoon, my father and I went to see the little duck, see a duck belly up, wings and feet in jitter, it sounds great, like crying. Dad put up little duck, duck down. I suddenly remembered that I took the little duck into the box,! I am a murderer! I cried. Little duck finally died, I am very sad.

Now we can hear the cries of tigers in the future even the Siberian tiger can be heard the cries.

小动物是我们的朋友，我们应该爱护它们。因为，有很多昆虫都对人类有益。比如说：蜜蜂，它很勤劳，每天早上很早就出去采蜜，一次又一次。到了天黑，吃几口蜜糖后，就马不停蹄地对采来的蜜进行加工。蜜蜂的外形并不起眼，生命也很短暂，只有3个月左右;可它一生都不休息，勤勤恳恳地工作，它们对人类毫无所求，却为人们酿造了甘甜可口、营养丰富、可医治病痛的蜂蜜。 还有青蛙，青蛙披着碧绿的衣裳，两只大眼睛，像两颗晶莹透明的玻璃球，它藏在田里，专吃害虫，保护庄稼。

一只鸟儿会唱出一首动听的乐曲，一首乐曲会奏出春天的旋律，而在春天的旋律里，谱写着人与鸟儿的和谐相处，让我们每天都能听见小鸟儿那动听的歌声。世界上如果一个国家和另一个国家不能和谐相处，那么世界将永无宁日。在这个社会上，如果人与人不和谐相处，那么社会治安就会受到影响。自然界中，如果人与动物不和谐相处，那么受伤害的不仅仅是动物，人亦难逃厄运。现在就让我们谈谈人与鸟儿的和谐相处吧!有一首歌，其中有一句是这样唱的：”草原鞭儿响四方，百鸟齐飞翔……多美啊!

许多鸟在蔚蓝的天空中翱翔，人们在一望无际的草原上骑着骏马疾驰，这种感觉就像在仙境中遨游一般。在大自然中，鸟儿给人类带来了无穷的快乐，当一个人在忧伤痛苦中难以自拔时，听到鸟儿在树枝上用清脆的嗓音唱出婉转的曲子时，忧伤痛苦顿时忘到脑后，却被那悦耳的歌声陶醉。

从总体来说，鸟是人类的朋友，自然界的生态平衡离不开鸟，人与鸟的和谐相处，是保护生态的平衡。其实，人类的朋友鸟儿也不想把病菌带给人类，他们也想和人类做好朋友!

一只鸟儿会唱出一首动听的乐曲，一首乐曲会奏出春天的旋律，而在春天的旋律里，谱写着人与鸟儿的和谐相处，让我们每天都能听见小鸟儿那动听的歌声。

The dog is one of the most popular pets in the world. It ordinarily remains loyal to a considerate master, and because of this the dog has been called mans best friend. Class distinctions between people have no part in a dogs life. It can be a faithful companion to either rich or poor.

Dogs have been domesticated for most of human history and have thus endeared themselves to many over the years. Stories have been told about brave dogs that served admirably in war or that risked their lives to save persons in danger. When Pompeii--the Roman community destroyed by Mount Vesuvius in AD 79--was finally excavated, searchers found evidence of a dog lying across a child, apparently trying to protect the youngster. Perhaps few of the millions of dogs in the world may be so heroic, but they are still a source of genuine delight to their owners.

A dog fits easily into family life. It thrives on praise and affection. When a master tells a dog that it is good, the animal happily wags its tail. But when a master scolds a dog, it skulks away with a sheepish look and with its tail tucked between its legs.

People in the city as well as those in other areas can enjoy a dog. Medium-size or small dogs are best suited for the confines of the city. Large dogs need considerable exercise over a large area.

Dogs are not always well thought of, however. In recent years dogs in the city have been in the center of controversy. Some people have criticized dog owners for allowing their pets to soil sidewalks and lawns, although in some cities laws oblige owners to walk their dogs along street curbs. In turn, dog owners have argued that the animals serve as protection against vandals and burglars and thus protect their detractors as well as their owners.

When a person decides to own a dog, he should be prepared to care for it properly. For a dog to stay healthy it must be correctly fed and adequately groomed, and its medical needs must be met. For a dog to be well-mannered it must be properly trained. It should never be ill-treated or mishandled. Otherwise, it will bite in its own defense.

The wild ancestors of all dogs were hunters. Wolves and other wild relatives of the dog still hunt in packs for their food. Dogs have retained the urge to be with the pack. This is why they do not like to be left alone for long. Some breeds of dogs still retain the hunting instinct.

Dogs exist in a wide range of sizes, colors, and temperaments. Some, such as the Doberman pinscher and the German shepherd, serve as alert and aggressive watchdogs. Others, such as the beagle and the cocker spaniel, are playful family pets, even though they were bred for hunting. Still others, such as the collie and the Welsh corgi, can herd farm or range animals. Each of the dogs just mentioned is a purebred. A mongrel dog, however--one with many breeds in its background--can just as easily fit into family life.

Dogs have been with humans since prehistoric times. Over the years they have performed various services. They have pulled sleds over snowy tracts. They have delivered messages, herded sheep and cattle, and even rescued persons trapped in the snow. Dogs have served as a source of food, too. The ancient Romans are said to have prized certain kinds of dog stew. The Aztecs of ancient Mexico raised tiny dogs, thought to be the forebears of the chihuahua, to feed the large carnivores in the private zoos of the Aztec rulers. In the past dogs have even been worshiped as gods. Recently, they have been used in drug research, medical experimentation, and space science. Soviet scientists launched dogs into space to test the ability of mammals to survive the rigors of space travel before people were sent up.

Dogs are trained as guard dogs in peacetime by the United States Army and other military services. Because of their keen sense of smell, dogs are used by police at times to track down escaped prisoners. Law enforcement agencies also rely on the dogs acute sense of smell to uncover illegal drugs. And specially trained dogs serve as the "eyes" of the blind, guiding the steps of their sightless masters around obstacles and hazards.

狗是世界上最受欢迎的宠物之一。它通常仍然忠于一个体贴的主人,因为这个狗被称为人类最好的朋友。人们之间的阶级差别没有生活在狗的一部分。它可以是一个忠实的伴侣,无论是富人还是穷人。

狗驯化在人类历史的大多数时期,因此球员很多。故事被告知关于勇敢的狗,令人钦佩的战争或冒着生命危险拯救的人处于危险之中。当庞培——罗马社区在公元79年被维苏威火山——终于被挖掘,搜索者发现一只狗躺在一个孩子的证据,显然试图保护这个年轻人。也许一些世界上数以百万计的狗可能是英雄,但他们仍然是一个真正的喜悦主人的来源。

一只狗容易符合家庭生活。在赞美和感情。当大师告诉一只狗,它是好的,动物快乐地摇尾巴。但当主人骂狗,它潜伏了一个羞怯的外观和它的两腿之间夹着尾巴。

城市的人们以及那些在其他领域可以享受一只狗。中型或小型狗是最适合城市的范围。大型犬在大面积需要相当大的锻炼。

然而,狗并不总是值得思考的。近年来狗在城市里一直在争论的中心。有些人批评狗主人允许宠物土壤人行道和草坪,尽管在一些城市的法律迫使业主限制他们的狗沿着街道散步。反过来,狗主人认为,动物作为防范破坏者和窃贼,从而保护他们的批评者以及它们的主人。

当一个人决定自己的一条狗,他应该准备妥善照顾它。狗保持健康必须正确美联储和充分培养及其医疗需求必须得到满足。狗必须得到适当的训练表现得彬彬有礼。它不应该虐待或处理不当。否则,它会咬自己的防御。

所有的狗都是猎人的野生祖先。狼和其他的野生亲缘狗仍然集体觅食的食物。狗有保留的冲动与包。这就是为什么他们不喜欢独处太久。一些品种的狗仍然保留了狩猎的本能。

狗存在大范围的大小,颜色,和性情。一些,比如杜宾犬,德国牧羊犬,作为预警和积极的监督者。其他的,如小猎犬和可卡犬,好玩的家庭宠物,尽管他们的狩猎。还有一些,比如牧羊犬和威尔士科基犬,可以群农场或范围的动物。每个狗刚才提到的一个纯种。一条杂种狗,然而——有许多品种的背景——可以很容易适应家庭生活。

狗自史前时代以来一直与人类。这些年来,他们已经在执行各种服务。他们已经把雪橇在雪大片。他们传递的消息,赶羊和牛,甚至救出被困在雪地里的人。狗也有担任过的食物来源。古罗马人据说炖珍贵的某些种类的狗。古代墨西哥的阿兹特克提出了很小的狗,认为是吉娃娃的祖先,给阿兹特克的私人动物园大型食肉动物的统治者。在过去的狗甚至被崇拜为神。最近,他们被用于药物研究、医疗实验,和空间科学。苏联科学家发射了狗测试能力的哺乳动物生存的艰辛太空旅行之前人打发了。

狗是训练有素的警犬在和平时期的美国军队和其他军事服务。因为他们的敏锐的嗅觉,狗被警察有时用来追踪逃跑的囚犯。执法机构也依靠狗的敏锐的嗅觉发现非法毒品。和受过专门训练的狗充当盲人的“眼睛”,指导的步骤失明的主人在障碍和危害。

老虎是生活在食物链顶端的一种动物，它关系到整个生物链的平衡。因此，保护老虎不单单是保护老虎这么一个物种的问题，而是保护整个食物链完整性的问题。

目前分布于我国的四个老虎亚种（东北虎、华南虎、孟加拉虎和印支虎）中，惟有华南虎是中国独有的。19世纪以前，华南虎曾经广泛分布于以我国东南部为主的国内广大地区。20世纪后，由于自然环境变迁、战乱纷扰及人类活动影响等多方面的原因，华南虎的分布区域不断受到挤压，分布地域面积逐渐缩校直至上个世纪80年代以前，由于捕猎和砍伐森林等活动，使华南虎赖以生存的栖息地受到破坏，华南虎的数量急剧减少。

据以往调查估算，目前中国处于野生状态的华南虎仅有20至30只，养殖在中国动物园里的数量也仅有60只，这仪数量比大熊猫还要稀少。在最近的一次野外考察中，甚至没有发现活的野生华南虎个体，华南虎已接近物种灭绝的边缘。

国家林业局全国野生动植物研究与发展中心的副研究员陆军介绍说，由于动物园中的数量有限，用于交配的华南虎之间的血缘关系越来越亲近，目前有的新产虎崽已经开始出现短尾（尾巴短一结）的现象。毫无疑问，如果任由这一趋势发展下去，在不久的将来，这一世界最濒危动物将不复存在。

透过虎类这一典型的例子，我们更应该保护动物，从自己做起，从他人做起，从身边的小事做起。让我们行动起来保护野生动物，共建和平家园世界将变得更美好。
