The giantPanda(Ailuropoda melanoleuca) ("black-and-white cat-foot") is a mammal classified in the bear family, Ursidae, native to central-western and southwestern China. It is easily recognized by its large, distinctive black patches around the eyes, ears and on its rotund body. Though technically a carnivore, the panda has a diet which is 98% bamboo. However, they may eat other foods such as honey, eggs, fish, and yams.

The Giant Panda is an endangered animal; an estimated 3,000 pandas live in the wild and over 180 were reported to live in captivity by August 2006 in mainland China[3] (another source by the end of 2006 put the figure for China at 221)， with twenty pandas living outside of China.[citation needed] However, reports show that the numbers of wild panda are on the rise.

The giant panda has long been a favorite of the public, at least partly on account of the fact that the species has an appealing baby-like cuteness that makes it seem to resemble a living teddy bear. The fact that it is usually depicted reclining peacefully eating bamboo, as opposed to hunting, also adds to its image of innocence. Though the giant panda is often assumed docile because of their cuteness, they have been known to attack humans, usually assumed to be out of irritation rather than predatory behavior.

The Giant Panda has a very distinctive black-and-white coat. Adults measure around 1.5 m long and around 75 cm tall at the shoulder. Males can weigh up to 115 kg (253 pounds)。 Females are generally smaller than males, and can occasionally weigh up to 100 kg (220 pounds)。 Giant Pandas live in mountainous regions, such as Sichuan, Gansu, Shaanxi, and Tibet. While the Chinese dragon has been historically a national emblem for China, since the latter half of the 20th century the Giant Panda has also become an informal national emblem for China. Its image appears on a large number of modern Chinese commemorative silver, gold, and platinum coins.

The Giant Panda has an unusual paw, with a "thumb" and five fingers; the "thumb" is actually a modified sesamoid bone, which helps the panda to hold the bamboo while eating. Stephen Jay Gould wrote an essay about this, then used the title The Pandas Thumb for a book of essays concerned with evolution and intelligent design. The Giant Panda has a short tail, approximately 15 cm long. Giant Pandas can usually live to be 20-30 years old while living in captivity.

Until recently, scientists thought giant pandas spent most of their lives alone, with males and females meeting only during the breeding season. Recent studies paint a different picture, in which small groups of pandas share a large territory and sometimes meet outside the breeding season.

Like most subtropical mammals, but unlike most bears, the giant panda does not hibernate.

Pandas eating bamboo at the National Zoo in Washington, D.C.Despite its taxonomic classification as a carnivore, the panda has a diet that is primarily herbivorous, which consists almost exclusively of bamboo. This is an evolutionarily recent adaptation. Pandas lack the proper enzymes to digest bamboo efficiently, and thus derive little energy and little protein from it.

While primarily herbivorous, the panda still retains decidedly ursine teeth, and will eat meat, fish, and eggs when available. In captivity, zoos typically maintain the pandas bamboo diet, though some will provide specially formulated biscuits or other dietary supplements.

大熊猫(Ailuropoda melanoleuca)(“黑白偷偷前进”)是哺乳动物分类在小熊一家,熊科,产于中国中西部和西南部。它很容易被大,独特的黑斑的眼睛、耳朵和圆胖的身体。虽然技术上一个食肉动物,熊猫竹子节食是98%。然而,他们可以吃其他的食物,如蜂蜜、鸡蛋、鱼、和山药。

大熊猫是一种濒危动物,估计有3000只大熊猫生活在野外,180多人被报道在囚禁2006年8月在中国大陆[3](另一个源图中国到2006年底将在221年),与二十熊猫中国以外的生活。[引文需要]然而,报告显示,野生熊猫的数量在上升。

大熊猫一直是最喜欢的公众,至少部分的物种有一个吸引人的事实婴儿的可爱,使它看起来像一个活生生的泰迪熊。事实通常是描述和平躺吃竹子,而不是打猎,也增加了其纯真的形象。虽然大熊猫通常认为善良,因为他们可爱,他们已经知道攻击人类,通常认为是刺激而不是掠夺性行为。

大熊猫有一个非常独特的黑白相间的外套。成年人测量长约1.5米,肩高75厘米左右。男性可重达115公斤(253磅)。女性通常比男性小,并且可以偶尔重达100公斤(220磅)。大熊猫生活在山区,如四川、甘肃、陕西、西藏。而中国龙已经在历史上中国的国徽,20世纪下半叶以来,大熊猫也成为中国的一个非正式的国徽。其形象出现在大量的现代中国纪念银、金、铂硬币。

大熊猫有一个不寻常的爪子,“拇指”和五个手指,“拇指”实际上是修改后的籽骨,这有助于熊猫竹子而吃。斯蒂芬·杰·古尔德写了一篇,然后使用熊猫的拇指一本书的标题文章关心的进化和智能设计。大熊猫有一个短尾巴,长约15厘米。大熊猫通常可以活到20 - 30岁住在囚禁的时候。

直到最近,科学家们认为大熊猫的大部分时间都是自己一个人住,与男性和女性会议只在繁殖季节。最近的研究描绘了一幅不同的画面,一小群熊猫分享大量领土和有时满足在繁殖季节。

像大多数亚热带哺乳动物,但与大多数熊,大熊猫不冬眠。

熊猫吃竹子在华盛顿国家动物园,华盛顿特区尽管其分类学分类作为一个食肉动物,熊猫的饮食主要是食草的,几乎都是由竹子。这是一个最近的进化适应。熊猫缺乏适当的酶消化竹子效率,从而获得一点一点能量和蛋白质。

虽然主要食草,熊猫仍然明显熊的牙齿,并将吃肉,鱼,和鸡蛋时可用。被囚禁,动物园通常保持大熊猫吃竹子,尽管一些提供特殊配方饼干或其他膳食补充剂。

In our common home - the earth, life with a lot of animal, which animal do you like? Anyway, my favorite animal is our most loyal friend - a dog.

My favorite is my neighbors dog that Beijing BaGou yuan yuan and collie handsome. They play together every day, it is a good friend of a stick dozen not scattered, I also like them, they saw I was shaking his tail towards me.

Handsome shape tiger is big, the body is about more than 60 centimeters long. Two leg, capable to my shoulders, his eyes, nose, mouth, ears are much older than yuan yuan, I most like to see him running figure - curly float in the sky, like a nice horse. I often and yuan yuan, running with the handsome, every time is handsome first, second, I am the third round. Can literally, handsome running faster than thoroughbred horse. Average dog ran up, send out "clicking" sound, but handsome rans voice is very small, not carefully is inaudible. The appearance of the handsome run is also very handsome, curly, bow shaped body. If you want to use a word to describe talent, that is: handsome. If you use a word that was impeccable.

Compared with the handsome, round shape is much smaller, only 30 centimeters in length and a half smaller than talent. The meaning of his name from his eyes, it is too round. Like a shiny black stones. And his legs are very round and round this is name. And his legs are very short, so even if he runs, casting its foot also run fast, but I still like him very much the kind of simple and lovely.

This is what I like animals, do you like?

Tigers live in the thick forests and small animals in the forests are tigers food.

During the past years,many forests have been cut down and the living conditions of the tigers are becoming worse and worse.There are fewer tigers left in the world now.Tigers are the animals of the world,and they should have their own living spaces.We must do our best to protect the tigers and their living environment.

My favorite animal is a dog, there is a small dog called small white mother kindergarten, it body hair is white, a pair of watery eyes, want to two bright pearls rolling, very agreeable.

It doesnt know me at first. On one occasion, my mother and I went to kindergarten, it is very fierce, I came so close to my legs, also good mother stopped it, the second day, my mother brought me in, little white saw my mom ran shaking his tail, mother said to the little white, of me, this is one of their own, dont bite well in the future. it look at me, his tail, on my feet smell the smell went away, so we met, I grew to like it.

我最喜欢的小动物是小狗，妈妈幼儿园里有一只小狗叫小白，它身上的毛是雪白的，一对水汪汪的眼睛，想两颗明亮的珍珠滚来滚去，很讨人喜欢。

起初它不认识我。有一次，我和妈妈去幼儿园，它对我很凶，差一点就咬到我的腿，还好妈妈叫住了它，第二天，妈妈带去我进去，小白看到我妈妈就摇着尾巴跑来了，妈妈指着我对小白说，，这是自己人，以后不要咬了好不好.它看看我，摇摇尾巴，在我脚上嗅了嗅就走开了，我们就这样认识了，我渐渐地喜欢上了它。

小白对妈妈最亲热，它每看到妈妈都会跑来缠住妈妈的脚汪汪叫，好像在说主人，给点吃的。妈妈说，忘记了，没有给你带。它不愉快的走开了。它对我也很亲热，有一次，它跑到我跟前要吃的，我只好把刚买的鸡腿给了它，它吃的狼吞虎咽，口中还发出呜呜声。它吃完鸡腿，我就逗它玩，它像风一样的跑着，我怎么也追不上，后来，它在草坪上等着和我玩。

这就是我喜欢我的小狗，一个讨人喜欢，尽职尽责的小狗。

panda is one of the scarcest animals. people in the world like it very much.

there used to be many pandas in china long ago. as the balance of nature was destroyed and the weather was getting warmer and warmer, pandas became less.

but at present, the number of pandas is increasing year by year. there are now so many pandas that some are being sent to other countries so that people there can enjoy them.

nowadays, the biggest nature park for panda in china is in sichuan. there is a research centre for nature and wild life there. scientists hope that one day they will have enough pandas to be set free and let them live in the wild again.

Advice on Protecting Wild Animal

Many animals are in danger of dying out。 As is shown in the chart， we can see the number of animal species decreases faster and faster and this trend will continue。 From 1980 to 2010， at least 1 million animal species have disappeared。 Worse still， more and more wild animals are in great danger。 It is not a piece of sensational news; it is a fact， a harsh reality。 Unfortunately， we may not see these animals in the near future。

很多动物频临灭绝的危险。图表显示，我们能够看到动物物种数量下降的速度越来越快，而且这种趋势将会持续下去。从1980年到2010年，至少有100万动物物种已经消失。更糟糕的是，越来越多的野生动物处于巨大的危险中。这不是一则耸人听闻的新闻，这是一个事实，一个残酷的事实。不幸的是，将来我们可能看不到这些动物了。

From the second picture， we can find some reasons。 Why is the number of animal species declining year by year? Apparently animals have bee victims of fashion industry。 Animal skin has been used to make fashionable clothes and these clothes sell at a high price。 So some greedy people begin to kill animals in a large quantity。 This irresponsible behavior not only breaks the balance of nature but also endangers the living environment of human beings。

从第二幅图我们能够找到一些原因。为什么动物物种的数量一年年的减少呢?显然，动物成为了时尚工业的受害者。动物的皮被用来做时髦的衣服，而且这些衣服都是高价出售。因此，一些贪婪的人就开始超多屠杀动物。这种不负职责的行为不仅仅打破了自然的平衡，而且使人类居住环境陷入危险。

As far as I am concerned， something must be done to stop this illegal action。 We believe "no buying， no killing"。 First， we must make concerning laws to protect these animals in danger。 Second， we must take some measures to protect animals effectively。 Animals are our friends and part of our environment。 Third， we should raise peoples awareness to protect animals and our environment。 In this way， we can build a harmonious society and ensure a sustainable development。

在我看来，我们务必要做些什么来阻止这种违法行为。我相信“没有买，就没有杀”。首先，我们务必制定有关法律来保护这些处于危险中的动物。其次，我们务必采取一些措施有效的保护动物。动物是人类的朋友，也是我们环境的一部分。再次，我们就应提高人们保护动物和环境的意识。这样一来，我们就能够建立一个和谐的社会，确保其可持续发展。

One Sunday afternoon, I casually adjust the TV channel. All of a sudden, disastrous scene into my line of sight: a peasant who was holding a piece of iron hammer, turned out to be a butcher is a not how big head of pig slaughter.

I saw all this. Found that pigs fate was so miserable! Is this fate arranged? Or pigs caused by past delicious lazy? I found the "people" are so cruel. Oneself have so long pig, cruel to kill it. Ah, I found that at the moment I was so sad, so sad, so lost, so helpless. In nature there are many more miserable than this things are happening, perhaps this is fate, it is inevitable in the growing of a test.

Not often say that animals are friends of human beings? Not often say that people for the ethical treatment of animals, protect the earth? Maybe this is just for those rare animals! Those animals that almost nearly perish! Pigs in a country of the world, one city, a town, a village, or even a home, a person can see. Pigs are a lot of, is not worth to treat? Pig also is to have life, and human beings, it also know pain, also have feelings, also know how sad. People for the ethical treatment of animals! The animals as their friends, for they give a little love!

Animals are friends of human beings, like humans, are the people of the earth. Let us hands reach out, to protect, to help those who need help human friends!

一个周日的下午，我漫不经心地调着电视频道。突然，惨不忍睹的一幕进入我的视线：一个农民模样的人正拿着一根铁棍敲打什么，原来是一群屠夫正在屠杀一头不怎么大的小猪。

我亲眼目睹了这一切。发现猪的命运竟是这么悲惨!难道这是命运安排好的吗?还是猪前世的好吃懒惰造成的?我发现“人”竟是那么狠心。自己养了这么长时间的猪，竟然狠心杀掉它。哎，我发现此刻自己竟是那么的伤心，那么的悲痛，那么的迷惘，那么的无奈。大自然中还有很多比这更悲惨的事情正在发生，或许这就是命运，这就是在成长中不可避免的一次考试。

不是常说动物是人类的朋友吗?不是常说善待动物，保护地球的吗?可能这只是针对那些稀有的动物罢了!那些几乎将近灭亡的动物罢了!猪在世界的某个国家，某个城市，某个城镇，某个村庄，甚至某家某户都可以见到。猪是很多，多到不值得善待?猪也是有生命的，和人类一样，它也知道痛，也有感情，也懂得伤心。善待动物吧!把动物当成自己朋友，对它们付出一点爱吧!

动物是人类的朋友，同人类一样，都是地球的子民。让我们伸出双手，去保护，去帮助那些需要帮助的人类的朋友吧!

Each of us has one, two, three, even four or five ideals. Remember Leo Tolstoy once said: ideal is the beacon. Without ideal, there is no secure direction; Without direction, there is no life.

Why do I want to be animal lovers? First: I particularly sympathetic to animals, such as some stray dogs, stray cats stray animals, Ill give them while mom and dad to leave some food to eat, they will initially with a grain of salt, (because they are often some selling dog meat, and the cat, temptation, then......) So I went far away, looking at them in a secluded place finished eating, I didnt leave. The second: I know about animals in particular, almost every day I see happy pets, there will be a little information about pets. Like our little teddy - cool, I can see the cool body movements to determine what it wants.

If we live for 20 years, 30 years, animal lovers really when me, I will be banned from kill the stray animals such as dogs, cats, explore the loch ness monster really is, a cure for hydrophobic drugs, the study and the most important thing is to protect the animals, prohibit cruelty to animals, to feed the animals... To protect the environment, only in this way can the animals survive, if we cant live without animals, such as cattle, help mankind to plow.

Although I have not yet when animal lovers, but I also calculate the half animal lovers, but I still call on everyone to protect animals, starts from oneself.

我们每个人都有一个、两个、三个，甚至四五个理想。记得托尔斯泰曾经说过：理想是指路明灯。没有理想就没有坚定的方向;没有方向就没有生活。

为什么我要当动物保护者呢?第一：我对动物特别有同情心，比如一些流浪狗、流浪猫之类的流浪动物，我会趁爸爸妈妈离开的时候给它们一些食物吃，一开始它们会半信半疑，(因为它们常常被一些卖狗肉，参猫肉的，引诱，然后就……)于是我就走的远远的，在一个隐蔽的地方看着它们吃完了，我才离开。第二：我对动物特别了解，我几乎每天都看快乐宠物，里面会有些关于宠物资料。比如我家的小泰迪——阿酷，我可以看阿酷的身体动作来判断它想要干什么。

如果再过上20年，30年，我真的当上动物保护者，我一定会禁止人们掠杀猫、狗之类的流浪动物，探索出尼斯湖水怪的真正面目，研究出治愈狂犬病的药物，还有最重要的事情就是要保护好动物，禁止虐杀动物，随便给动物喂食……要保护好环境，只有这样动物才能生存下来，如果没有动物我们也无法生存的，比如说牛，帮助人类耕田。

虽然我还没有当上动物保护者，但我也算半个动物保护者了，但是我还是要呼吁大家保护动物，从自己做起。

My home have a lovely and naughty little white dog, its name is small white.

The small white to sleep. A noon, it will find a warm place, carefree played a big sleep, no matter what you call it, call it, its like not to hear, in the left ear, right ear out, dont ignore you.

Once in it when sleeping, I secretly hid the its food, it woke up, cant find my dinner, it is like a cat on hot bricks, like boiled dumplings, worried, "wang wang" barked, seems to shout "things I? Im not hungry!"

Suddenly, it triumphantly walked to come over to see me, like Sherlock Holmes, seemed to have answers, eyeing up and looked at me and after a while, quickly ran up and grabbed my trousers, tried to pull back, I also dont be afraid, go forward hard, alas, because of the small white teeth are sharp, so I was it to pull over.

Small white repeatedly "begged" me, his eyes reveal anxiously look, Im helpless, gave it the food into the cupboard.

Small white immediately as found the family dog, mingled, as if in said "thank you, master!"

How, this is the interesting thing between I with small white!

我家有一只既可爱又淘气的小白狗，它叫小白。

小白贪睡极了。一到中午，它就会找个暖和的地方，无忧无虑地睡起了大觉，不管你怎么叫它，喊它，它都像没听见似的，左耳朵进，右耳朵出，一点也不理睬你。

有一次，在它睡觉时，我偷偷地把它的食物藏了起来，它醒时，找不到了美餐，简直是像热锅上的蚂蚁，又像沸腾了的饺子，心急如焚，“汪汪”地叫个不停，似乎是在喊“我的事物呢?我饿得不行了!”

忽然，它看见我得意洋洋地走了过来，像福尔摩斯一样，似乎有了答案，便虎视眈眈地看着我，过了一会儿，迅速地跑过来，咬住了我的裤子，拼命地往后拽，我也不干示弱，使劲地往前走，唉，由于小白的牙齿锋利，所以我被它拉了过去。

小白再三“恳求”我，眼睛里露出了焦急地神情，我无可奈何，把藏在柜子里的食物给了它。

小白顿时像找到了家的小狗一般，悲喜交集，好象在说“谢谢你，好主人!”

怎么样，这就是我和小白之间有趣的事!

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。

Protecting the Wild Animals

Last week, I saw a very impressive documentary about panda. A professor studied panda in the early 1980s went to the wild life and kept trace of wild giant panda for many years. As a result, he found that it was human being that made these lovely animals die out. At that time, many people believed that giant panda became less because of the low rate of newborn babies. But it was not true. People cut trees for making profit at that time. Panda lose homeland and they lacked of food. Thanks to these valuable data, the government took the policy to protect the animals. So today, the number of giant panda is increasing. People realize the importance of protecting the environment and it is the best way to protect wild animals, they are the indispensable part of the nature.

上周，我看了一部令人印象非常深刻的关于熊猫的纪录片。一位教授在20年代80年代早期就开始研究熊猫，他到野外生活，多年寻找野生大熊猫的踪迹。结果，他发现，正是人类，让这些可爱的动物面临灭绝。当时，许多人认为，大熊猫变少是因为新生儿的低出生率。这是不正确。人们为了利益砍伐树木，熊猫失去了家园，也没有食物吃。多亏了这些有价值的数据，政府采取了政策去保护它们。所以现在，大熊猫的数量正在增加。人们意识到保护环境的重要性，这也是最好的方法来保护野生动物，因为它们是大自然不可或缺的一部分。

It is known to everyone that the unrestrained slaughter of wild animals has diminished the number of some endangered species. More and more species are being driven to extinction every year. It is terrible to think that magnificent animals are being sacrificed to human vanity

There are already laws enacted to prevent the importation of rare animals and the products made from their flesh, skin and bones.

These laws must be strictly enforced. Violators of these laws must be severely punished .Moreover, the public must be informed about the natural treasures we stand to lose .If we don’t take immediate action, we will be depriving future generations of our most precious heritage.

In Taiwan, because most people do not understand the importance of wildlife, the wildlife is in a poor situation. We Chinese are fond of eating anything delicious, so there are many animals killed by hunters. People enjoy eating tigers, bears, birds, and lions, so there are fewer and fewer birds flying in the sky and fewer and fewer bears running here and there in the forest. Instead, we often see them for sale at the market. How poor they are! And how cruel we are!

In my opinion, we should try every possible way to preserve wildlife. First, no one is allowed to hurt any wild animal. Second, the authorities concerned should punish those who kill any wild animal. Third, we should pay more attention to those endangered species to protect them from being eaten. If we can do so, nature must become very beautiful.

June 23rd Sunday Sunny

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.

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.
