小朋友，你们抓过小蝌蚪吧，你们一定知道蝌蚪长大要变成小青蛙，青蛙可以吃害虫，所以青蛙是我们人类的好朋友。我们应该保护它，而不是伤害它。 可是有些饭店还卖青蛙肉呢。有一次，爸爸和他的朋友带着我去吃饭。一位服务员过来说：“您看，这是我们店新推出的特色菜，爆炒田鸡球”。“田鸡是什么 呀?”我好奇地问，“田鸡是青蛙。”服务员笑着说道。我当时很气愤，因为他们伤害了我们的好朋友——青蛙!还有一件事，他对我有很大的启发。一天，我放学 的时候，看见一个人在学校门口卖小鸡仔，我好可怜它们。因为小鸡仔刚来到这个世界上，就远离了妈妈，远离了母爱和妈妈温暖的怀抱，这也使它们面临着饿死、 冻死的危险。当时我想到了：我们人类是多么幸福啊!当你看到这里时，你是不是明白了要保护我们人类的朋友——动物呀!

My rabbit

I have a pretty rabbit. She wears a white coat. She has two red eyes. She has Long ears. My rabbit likes carrots and vegetables. But it doesn’t like taking a bath. She can run and jump. It likes plating and eating. I have a small football and my rabbit likes playing football with me very much.

I like my rabbit. Do you like my rabbit?

nimals 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 alone are considered in danger.

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.

动物是自然资源，在整个历史过程中，人类一直在糟蹋着这种资源。人们杀死动物，获得它们的皮毛，把它们当作食物或运动方式，或者只是因为它们碍事。成千上万种动物已经从这个地球上永远地消失了。现在另外上百种动物也上了濒危动物名单。仅荚国大概就有170种被认为处于危险当中。

为什么人们应该感到担忧呢?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。它们不仅仅是人类的食物来源。在维持自然平衡中，每种动物都有其作用。毁灭某种动物会导致许多问题。比如，农民们如果杀死为数众多的鹰，他们谷物和粮食的仓库就会受到老鼠和田鼠的破坏。 为什么?因为鹰吃鼠类，没有鹰控制它们的数量，鼠类就会迅速繁殖。

幸运的是，有些人正在努力帮助拯救这些动物。有些组织筹钱以便人们了解这一问题。他们也努力使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

律禁止杀害濒危名单上的动植物。某些濒危动物的数目正在慢慢地不断上升。

Rabbit is an cute kind of amimals.It has two long ears.They can make rabbits hear carefully.It also has a short tail，which makes rabbits so lovely.Rabbits likes eating carrots.If you feel lonely.You can keep a rabbit.It can be your good friend.

兔子是一种机灵的动物，它有两个长耳朵，它们可以让兔子清楚地倾听。兔子还有一个短尾巴,让兔子更可爱。兔子喜欢吃胡萝卜，如果你感到孤独，你可以养一只兔子，它会成为你的朋友。

snakes蛇

the snake is a long and thin animal that lives in grass or other dark places. 蛇是一种又长又瘦的动物，生活在草丛里和阴暗的地方、a snake has no legs or feet, but it can move very fast on its stomach.蛇没有腿和脚，靠胃部飞快的移动前进。 snakes usually have green,

yellow or black skins, which make them difficult for their enemies to find them. 蛇常常有绿色，黄色和黑色的皮肤，使得敌人很难找到他们。some kinds of snakes live in water. they can swim as freely as fish.有些蛇生活在水里，他们能像鱼一样飞速的游移。

snakes are cold-blooded animals. in winter they hibernatein holes which are narrow enough only to hold the snakes bodies. the snakes can sleep through a whole winter without eating and moving. they can not feel any pain. the hibernation period lasts about five months. when spring comes, the snakes come out and begin their normal life. snakes can take many things as food, such as mice, sparrows,

frogs,birds eggs, pests and so on. people sometimes can see a snake eat a sparrow. first it moves close to the sparrow, then it puts out its tongue and brings the sparrow into its mouth and swallows it, which makes a lump in the snakes body. after some time the lump disappears.

as snakes are dreadful-looking, people are afraid of them. many people drive them away whenever they see snakes. but in chinese fairy tales, snakes are by no means bad. they seem to have human feelings.

they can change into pretty girls. people like and respect them. the most well-known is the story about the white snake and the blue snake. in fact, snakes are not as dreadful as they look. they can help us to kill mice and pests. they can provide us with delicious meat. their blood is a good drink. poisonous snakes are especially useful. we can make valuable drugs with them.

导语：人类正试图猎取野生动物以获取更大的利润，下面是yuwenmi小编为大家整理的优秀作文，欢迎阅读与借鉴，谢谢!

As is often read in the newspaper reports, wild life especially the rare species is 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. So it is high time for us to take quick action to protect them. First of all, its quite necessary for every citizen to realize the importance of animal protection. Only by knowing its importance can people develop a sense of responsibility. People will surely take it for granted to have the duty to prevent any killing of wild animals. So a national publicity campaign should be launched, thus giving animals a good living environment. In addition, the government should pass some laws to forbid any hunting of rare animals. We dont expect anything harmful to wild life to happen again.

If everyone is involved in the protection of wild life, were sure man will be a good friend of animals rather than their enemy.

【参考译文】

正如报纸上经常看到的那样，野生生物特别是稀有物种面临灭绝的危险。人类正试图猎取野生动物以获取更大的利润，当然，这会导致动物数量急剧减少。所以现在是我们采取行动保护他们的时候了。首先，每个公民意识到保护动物的重要性是很有必要的。只有认识到它的重要性，人们才能产生责任感。人们一定会想当然地认为有责任阻止野生动物的捕杀。开展全国性宣传活动，为动物创造良好的生存环境。此外，政府应该通过一些法律，禁止猎杀珍稀动物。我们不希望发生任何对野生动物有害的事情再次发生。

如果每个人都参与野生动物的保护，我们相信人类将是动物的好朋友，而不是敌人。

Animals are friends of human beings. Most of them are lovely. I like giraffe the most. They are very tall and have many brown spots. They have very long necks, so that they can eat the leaves in high trees. Giraffes are gentle and lovely. They are friendly to people. When I go to the zoo, I always look at them. They move slowly. I can’t keep it as a pet, because it’s so huge. It’s a big pity.

动物是人类的朋友，大部分的动物都很可爱。我最喜欢的是长颈鹿，它们很高而且又很多棕色斑点。它们的颈很长因此可以吃到大树上的叶子。长颈鹿温驯可爱，它们对人类很友善。当我去动物园的时候我总喜欢去看它们。它们动作缓慢。我不能把它当宠物因为它太大了，这有点遗憾。

我喜欢狗.我家有一只狗.这只狗是灰色的.它有两只眼睛,两只耳朵,一个口和一个灵敏的鼻子.它会跑步和吃东西,还会游泳.它非常可爱,我非常喜欢它.

There is a saying"Dog is humans friend."There are too many clever dogs aroud us.I have a friend.The firend has a dog.Its name is Peter .Peter is very clever and clean.Every afternoon my firend takes Peter for a long walk outside.Peter likes these long walks very much.He is very happy at this time.One Sunday afternoon a young man came to visit my friend.He stayed a long time.He talked and talked.Soon it was time for my friend to take Peter for his walk.But the visitor still talked.Peter began walking around him to attract him.But the visitor didnt know his meaning and paid no attention.He continued talking.Finally Peter couldnt bear it.He went to the corner of the room and brougut the visitors shoes in front of him and then he held the visitors bag in his mouth and ran our of the room."You should leave our home,"Peter thought.

有句老话说“狗是人类的朋友.”在我们身边有很多很机灵的狗.我有一个朋友,他有一只狗.狗的名字叫彼得.彼得是一只很聪明并且很干净的狗.每天下午我的朋友都带着彼得在外面散步很长时间.彼得很喜欢散步.每当这个时候它都很开心.一个星期天下午一个年轻人来拜访我的朋友.他呆了很长的时间,一直在和朋友聊天.很快到了我的朋友要带着彼得出去散步的时候了.但是来访的朋友还没有要走的意思,还是不停说啊说.彼得开始围着来访的人转,并且开始攻击他.但是来访者还是不知道彼得的意思并没有注意它,继续说着话.最终彼得再也忍受不了了.它走到房子的一个角落,把来访者的鞋子弄到他的面前,并且用嘴巴叼着他的包跑出房间.彼得想,你必须离开我的家

哥哥家养了一只小狗狗，因为小狗长得很壮实，所以哥哥给小狗狗取名叫“肉肉”。

Brother a small domesticated dog, because the dog is very strong, so the elder brother to the little dog named "meat".

肉肉长得非常漂亮，人见人爱。它全身长着黑色的皮毛，那条翘着的小尾巴，总是不停地摇来摇去，那双水晶似的大眼睛，总是充满着好奇，不停地到处张望。

I was very pretty, cute. It was a long black coat, that raised a small tail, always keep the to and fro, pair of crystal like eyes, always full of curiosity, constantly looking around.

有一天，我去哥哥家玩。一到门口，肉肉就站在门口迎接我，我就扮着鬼脸想去摸它，肉肉吓得立即逃走了。晚上，我和哥哥在床上玩游戏，肉肉走过来，把头放在床边，哥哥就帮它按摩，还用梳子梳理着它的毛发。肉肉很通人性，不停地摇摆着小尾巴，好像在说：“谢谢小主人，谢谢小主人。”。

One day, I went to my brothers house. One to the door, I stand at the door to greet me, I made a face to touch it, I immediately scared away. At night, my brother and I play games on the bed, I walked over, put his head on the edge of the bed, my brother will help it massage, also comb his hair. The meat is the human nature, rocking the small tail, as if to say: "thank you, master, for the master.".

因为肉肉，我更喜欢去哥哥家玩了。

Because meat meat, I like his brother play.

我喜欢的小动物是海龟，它有一个圆圆的脑袋，可以在龟壳里自由伸缩。它有一个厚厚的外壳，那个壳既像是它的家，又像是它的盾牌，可以阻挡危险，保护自己。它的脚不像乌龟那样有一个个小爪子，而是像扇子一样扁平扁平的。在海洋里，它能像鱼儿一样在水中随心所欲地游来游去，这与它像扇子一样的脚有很大关系。海龟只有离开水后便爬着走，那速度才是真正的龟速。

My favorite small animal is the turtle, which has a round head and can flex freely in the shell. It has a thick shell, which is like both its home and its shield. It can stop danger and protect itself. Instead of having a small claw like a tortoise, its feet are flat and flat like a fan. In the ocean, it can swim freely in the water like a fish, which has a lot to do with its fan-like feet. Turtles only crawl away from the water, and that#39;s the real speed.

海龟产卵的时候不像其它动物妈妈一样产完卵就不管了，而是用沙子将卵藏好，以防其他动物偷吃，真是一位贴心的妈妈。它们的窝更是奇特，别的动物的窝都是用沙土堆起来或是在陆地上打一个洞，而海龟则是在海底打一个洞住进去。小海龟出生一个月后，海龟妈妈就不会再管自己的宝宝了，而是让它们自己生活下去，让它们学会自己成长。

Turtles do not lay eggs like other animal mothers. They hide eggs in sand to prevent other animals from stealing them. It#39;s really a kind mother. Their nests are even more peculiar. Other animals#39;nests are piled up with sand or made a hole in the land, while turtles make a hole in the sea floor. One month after the birth of the baby turtle, the mother of the turtle will no longer take care of her babies, but let them live on their own, let them learn to grow up.

这就是我喜欢的动物，海龟。

This is my favorite animal, the turtle.

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. Everybody loves panda, it is so lovely, a panda has two black eyes, it is very lazy, it likes sleeping all the time. When we see its round body shape, we can’t help loving them. In order to see the lovely animal, we need to protect them. We must protect the environment, like not to throw the rubbish away, not to cut down the trees. We condemn such behavior that killing the animals. Protecting the animals is everybody’s job.

熊猫是我们国家的珍宝，我们应该保护它。现在，我们可以从电视上看到熊猫比以前少，这不仅因为环境的破坏，还因为熊猫自身的脆弱。大家都喜欢熊猫，它很可 爱，熊猫有两只黑色的眼睛，很懒，总是在睡觉。当我们看到熊猫圆圆的身形时，忍不住喜欢它们。为了看到这些可爱的动物，我们需要保护它们。我们必须保护环 境，比如不随处扔垃圾，不砍伐树木。我们谴责杀动物的行为。保护动物，人人有责。

Animals are our good friends. People should be friendly to them. But now, many people in China as well as in the world kill animals in order to get money. Its well known that there are many kinds of rare animals in China, such as pandas, golden monkeys and so on. Some people catch or kill them. They use their furs and skins to make clothes and shoes or eat their meat. As a result, a lot of rare animals have disappeared.

What a pity!

At present, our government have made some plans to punish these people. Recently, some nature parks have been built. Lots of money collected for protecting them. For example, some students put on perfom ances or have other kinds of activities to collect money for rare animals.

Its our duty to protect wild animals. As nature is like a big family, man and animals must live together in it peacefully. We must keep the balance of nature. If we do like this, our world will become better and better.

动物是人类的好朋友，人们应该善待它们，但现在，中国和世界上的许多人为赚钱而捕杀动物。众所周知，中国有许多珍稀动物，如熊猫、金丝猴等。一些人捕杀它们是为了用它们的皮毛制衣制鞋，或是为了食用它们的肉。

结果大量的珍稀动物死亡了，真可惜呀!

目前，我国政府已制定出有关严惩不法分子的法律;近来又建起了一些自然公园;人们：也捐款来支持保护动物的活动，如，有些学生通过义演或用其它方式为保护珍稀动物积极筹款。

我们有义务保护野生动物，因为自然就像一个大家庭，人类和动物必须和平共处：我们必须保持生态平稳。

如果人类能这么做，这个世界就会越来越好。

Do you know what kind of animal I like most? It’s monkey. Monkey is a kind of lovely animal.

Many people like monkeys very much. Generally, monkey has small body covered with fur. Some kinds of monkeys have two big eyes and ears and a long tail. I can see them on TV or the zoo.

Every time I go to the zoo, I will go to see them.

Monkeys often stay in trees and jump between them. They are so lively and favorable. When they are happy, they will act for visitors. It’s very funny.

We need to protect wild animals, because we protect wild animals, wild animals will be very friendly to us.

Like the swallow, swallow can help us to eat the pests in the field. If we human beings killed to catch them, they will eat mosquitoes that often to scratch faze us, let us better life? Without the swallow around us become many insect pests, these pests have great harm to our human!

I have an example. For example the frog, the frog can also help us to eat the pests in the field, can be said to be the police in the field. Once we kill them, not the frog, the pests in the field more and more, pest constantly eat vegetables, dont we will have a good harvest?

I have an example. Such as w, w is a doctor in the forest, it can help us to eat the pests in the tree, the tree back to health. We killed them, pests will be more and more trees, trees will slowly decrease. No trees on earth, floods, earthquakes.

My last an example. Such as owls, catch rats, the owl is good for us human beings, human is often hunt them. No owls, voles will increase. Rats ate the crops and vegetables is more, we human beings did not have a good harvest.

So, we need to protect more than animals. At the same time, we also need to protect other wild animals!

我们要保护野生动物，因为我们保护野生动物，野生动物对我们人类也会很友好。

比如说燕子，燕子能帮我们把田里的害虫吃掉。如果我们人类杀害捕捉它们，它们会吃掉那些常常来搔扰我们的蚊子，让我们更好地生活吗?没有了燕子，我们的周围变得很多害虫，这些害虫对我们人类有很大的坏处呀!

我还举个例子。比如说青蛙，青蛙也能帮我们吃田里的害虫，可以说是田里的警察。我们支捕杀他们，一旦没有了青蛙，田里的害虫越来越多，害虫不断地吃菜，难道我们会有美好的丰收吗?

我还举个例子。比如说啄木鸟，啄木鸟是森林中的医生，它可以帮我们吃掉树里的害虫，让树恢复健康。我们杀害它们，树木的害虫会越来越多，树木会慢慢地减少。地球上没有树，会发洪水、地震。

我最后举个例子。比如说猫头鹰，猫头鹰捉田鼠，是对我们人类有好处的，人类却常常捕猎它们。没有猫头鹰，田鼠会增加。田鼠吃的庄稼和菜就更多了，我们人类一样没有好的收成。

所以，我们要保护以上的动物。同时，我们还要保护其他的野生动物!

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。

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。

导语：很多东西都面临灭绝的危险，我们应该保护动物，下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!

Many wild animals are facing the danger of extinction, because the environment that they are living in has changed greatly. For example, with the developmet of cities, the using of insecticide and serious pollution, their living areas have become narrowcr and narrower. Many of the wild animals, now are confronted with food crisis. At the same time, man is killing off species just for getting their fur, skin, horns, teeth and meat.

In order to protect our resources of ecology, people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty. There fore, measures of the following should be taken: pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life, reserves.

Only if we human beings take some drastic measures can wild animals be preserved.

【参考译文】

许多野生动物正面临灭绝的危险，因为它们生活的环境已经发生了巨大的变化。例如，随着城市的发展，杀虫剂的使用和严重的污染，他们的生活区域变得越来越狭小。许多野生动物现在面临食物危机。同时，人类为了获取皮毛、皮肤、角、牙和肉而捕杀物种。

为了保护我们的生态资源，人们应该意识到任何物种的损失至少是知识的源泉和自然美的源泉。因此，本应采取以下措施：制订污染标准以降低有毒物质;严禁杀害某些稀有物种;应建立国家公园作为野生动物，保护区。

只有人类采取一些激烈的措施，野生动物才能被保存下来。
