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。

我们每个人都有自己喜欢的动物,那么,关于介绍动物的英语作文应该怎么写?今天小编为你整理了关于介绍动物的英语作文,希望对你有用。

The snake is a long and thin animal that lives in graor 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.

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.

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.

My favorite animals are swans.they are white.they can swim very well.I think they look like a beautiful girl in a white dress.they have a pair of wings and they can also fly well.I believe they are angles from the sky.they bring us love and make us happy.they are always friendly to us.We cant hurt them,because they are our friend.I love them!I like dogs,too.they are not beautiful,but they are the best friends.they keep the thieves away.Dogs have the best listening and eyes.they can hear in the nosiy,see in the dark.If we are in danger,they will help us at once.And they dont mind their lives.So,I love them.

Elephant is the largest animal on land today. It weights some ninety kilograms and is about one metre high when born. When it is 12 years old, it studs over three meters and does not grow any more. Elephant is usually grey in color, having a long trunk with large ivory tusks protruding from each side of its mouth. Usually moving in groups and caring for each other, Elephant is know to be a very and gentle creamre. For many years people have used the strength of these poweful animals to move trees and heavy logs. Elephant has been and is a vital tool for people to do many things that would normally be imposs-ible. Elephant is and will continue to be one of the greatest creatures man has ever come into contact with. Its size. beauty, and power willforever be useful to man.

Nowadays more and more people keep animals as pets; they treat them as their family members. But there is someone who likes to torture animals. They do this for some reasons: they don’t like animals, they get fire or they are just not happy. Some people think it’s fine to torture animals, because people are suffering more pressures than before; they need some way to be relaxed. In my point of view, I think animals deserve better.

In the first place, some animals are kept as pets in family. They are a part of it, like dogs or cats. They can bring people happiness. Lost of parents have pets for the reason that it could help their children learn to care about others; they think it’s a good way to teach children to be a good person. For the single people, pets could be a good companion, especially for an introvert, they prefer to talk to an innocent animal better than a person who is wearing a mask.

In the second place, people who are like to torture animals may have some psychological problems. If someone is suffer too much pressure that they couldn’t breath, they should find a healthy way to release it, for instance, they could go to swimming, jogging or climbing. They don’t have to hit pets to release their anger. Some people even cut pet’s ear or claw or had pet’s eyes gouged out. This is really sick; it’s hard to understand that what kind of people would hurt an animal when they are look into their innocent eyes.

In sum, animals is a lovely creature that made by god to bring happiness to human beings. People should treat them better than torture them.

现在越来越多的人把动物作为宠物,他们对待他们的家庭成员。但有喜欢虐待动物的人。他们这样做有一些原因:他们不喜欢动物,他们得到火灾或他们只是不开心。一些人认为它很好折磨动物,因为人们的痛苦比以前更多的压力,他们需要一些放松的方法。在我的观点,我认为动物应该得到更好的。

首先,一些动物作为宠物饲养在家庭。他们是其中的一部分,像狗或猫。他们可以给人们带来幸福。失去父母的养宠物的原因,它可以帮助他们的孩子学会关心别人,他们认为这是一个好方法教孩子成为一个好人。单身人士,宠物可能会是一个好伴侣,尤其是对于一个内向的人,他们更喜欢跟一个无辜的动物比一个戴着面具的人。

第二,喜欢虐待动物的人可能会有一些心理问题。如果有人受到太多的压力,他们无法呼吸,他们应该找到一个健康的方式来释放它,例如,他们可以去游泳,慢跑或爬山。他们没有达到宠物释放自己的愤怒。有些人甚至把宠物的耳朵或爪或宠物的眼睛剜了。这是真的病了,很难明白,什么样的人会伤害动物当他们看着他们的无辜的眼睛。

总之,动物是一种可爱的动物,由上帝给人类带来幸福。人们应该对待他们比折磨他们。

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.

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.

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。
