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.

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, that's what's supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So what's 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.
"We've 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 we've 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 Manitoba's 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 that's going to help supplement against longer ice-free seasons, that really doesn't 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; they're 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 that's going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when there's sea ice."
Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, can't 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。

You know, there's a lovely puppy in the aunt's house. It has white hair all over the body, white as cotton candy; its eyes are black and white, like two precious stones; ears are semicircle, nose is black, tail is short. It's really beautiful!
One day, I went to the aunt's home to play. As soon as I entered the door, I saw the dog barking in the doorway, as if welcoming me to his house. I saw it, smiled and said: "small naughty, do not worry, I will play with you immediately!"."
As I entered the room, I sat down on the sofa and wanted to rest for a while. But it licks me with its tongue. I can't stand this kind of "affectionate" reception, so I have to go out with him.
Outside, we played hide and seek. I hid in the middle of the back of the car, waiting for it to come to me. After a while, I saw him running nimbly towards this place. Suddenly, it came to me with a slam on the brakes, but it didn't realize my existence. So I decided to come and see what it was like.
It was the body of the hair, like a bath. It spat out its tongue against the sun. Yes, the weather is so hot today, just like the fire on the ground. But it also found me at this time. Ah! It become more lovely! Light shining white hair, looks very smooth. Its eyes were fixed on me, a smile on my face, as if to say, "look, boy, I've found it."".
I really like this cute puppy!

My favorite animal is the dog. Dogs are the most loyal animals to people.
My family also has a dog, its name is lu lu, is a male dog. It was a shish dog, covered with long, golden hair and felt soft and comfortable. It had big black eyes and a twinkle in the evening. There's also a lovely flat black nose that is always wet, so it likes to lick its nose. There was a cute little braid tied to the head, and a red bow tied to the braid.
It has been with me since I was a baby. I remember one time I made a mistake and my mother was going to hit me. Lulu saw it, and ran quickly, Shouting at her mother, trying to protect me, and her mother gave up.
My dog has a skill that other dogs don't, and whenever I play the harmonica, it will sing in rhythm, in a deep, sometimes high-pitched way. I think it's going to be a concert of its own! Do you mean my dog is tough?
So, I like dogs very much.
我最喜欢的动物是狗。因为，狗是对人最忠诚的动物。
我家也养了一只狗，它的名字叫噜噜，是一只公狗。它是一只西施狗，浑身上下长满了长长的金黄色的毛，摸上去软软的，舒服极了。它有一双黑黑的大眼睛，一到晚上就会发出闪闪的光芒。还有一只可爱的扁扁的黑鼻子，上面总是湿漉漉的，所以它总喜欢舔自己的鼻子。噜噜的头上还扎着一个超可爱的小辫子，辫子上还扎着一只红色的蝴蝶结，分外耀眼。
从我还是婴儿的时候起，它就开始陪伴着我成长。记得有一次，我犯了一个错误，妈妈要打我。噜噜看见了，就飞快地跑过来，对着妈妈凶狠地大喊大叫，想要保护我，妈妈见它那么凶，只好放弃了。
我家的狗还有一个别的狗没有的本领，只要每次我吹响口琴时，它就会按节奏唱起歌来，时而委婉深沉，时而高亢激昂。我想，它肯定能开一个属于自己的演唱会了！你说我家的狗厉害吗？
所以，我非常喜欢狗。
