At this time, a female neighbor because of badly wounded, riza, please take your a pair of twins, she then back up the twins. To fight with in the jet stream, she saw a big snake down the flood from the left to swim, she is just like the serpent has been to swim, the results arrived in a safe place.

Yes, as long as we treat animals, animals will be kind to you, but if you hurt the animals, which hurt just dont know is you a person but a human. In recent years my human destruction of the food chain, all the time and so many animals die because we humans, spirited, extinction. Some even have some rare animals fur to make clothes for money! Some people regard animals as the experiment, according to statistics, there are 2.5 million animals die each year from drug test, in this world, animals are used in shampoo, cosmetics, cancer drug test, although it is not the same with animals, but people and animals have the same right to life, they also have a desire to survive, so human cant go to such a large number of experimenting on animals. Now so many animals came to attack us, because we damage to them, so want to animals will also be kind to you, you will be kind to animals.

最近我看到过一个这样的故事，这个故事讲着一条巨蛇引路救妇女是在在印尼亚齐省省会班达亚齐，一名女子在一条大蛇的指引下，抵达安全地点。26岁女子丽扎说，2004年12月26日，她住的村落被巨浪淹没，慌乱中人们纷纷逃命。

这时，一名女邻居因为受了重伤，请丽扎带自己的一对双胞胎逃生，她于是背起了双胞胎。在与急流搏斗时，她看见一条大蛇从左侧顺着洪流游去，她就跟大蛇一直游，结果抵达了安全的地方。事后，丽扎说："很奇怪，当时见到大蛇，我并不感到惊慌。"而且，大蛇也没有咬她们。

是啊，只要我们善待动物，那么动物也会善待你，但如果你伤害了动物，哪受伤害的就不知是你一个人而是人类。就在近些年来我人类时时刻刻都在破坏着生物链，而因此许多动物都因为我们人类的搏杀而死亡、灭绝。甚至有些人为了钱把一些珍稀动物的皮毛做成衣服!还有些人把动物当成了实验品，据统计每年有250万的动物死于药物试验，在这个世界，动物们被用于洗发水，化妆品，癌症药品的试验，人虽然与动物是不相同的，但人与动物却有着相同的生存权利，它们也有求生的欲望，所以人类不能去这样大量的用动物做试验。现在之所以这么多的动物都来攻击我们，是因为我们对他们的破坏，所以要想动物也会善待你，你就要善待动物。

Animals 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 plant on the danger list。 Slowly， the number of some animals in danger is growing。

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!

Grilled chicken. The roast duck. All kinds of meat, already is normal on table a "routine". Television also reported many save a national protected animal, encourages people from all over the world to protect animals. But, why do some people will do whatever it takes to save animals, and some will be on the table for people to enjoy? Not advocate protect animals?

The answer is very simple, because people at all costs to save animals is called "the state-level protection", and was called "poultry" on the table. Why is that? They are also lively individual life; There are also mom and dad love; a lovely kid The same is collectively known as animals. However, why? To protect rare animals, but more to eat. Side in the title of "animal protection", there are big mouth to bite a serve fish or fowl. Why the national birth will be protected, live more comfortable than some vulnerable groups, and poultry was born is raised, waiting for them is cruel, and then made into a variety of delicious, is on the table, is to eat their meat.

Isnt their life life? Why do this to them? If one day, in our own to be they kill, and then made into a variety of delicious, for them to enjoy, our own feelings of what?

Although I was not a great writer, cannot use a beautiful sentence touched your heart, but I want to say only one forever, also is the life should be respected, we have no right to decide the life and death of others, feeding them, at best, is the behaviour of a love.

Their life is life, watching, please protect your side weak life, thank you!

烤鸡;烤鸭;各种各样的野味，早就是餐桌上见怪不怪的一道“家常便饭”了。电视上也报道过不少拯救国家级保护动物的节目，提倡世界各地的人们要保护动物。可是，为什么有的动物人们会不惜一切代价去挽救，而一些就要被摆在餐桌上供人们享用呢?不是提倡保护动物吗?

答案很简单，因为人们不惜一切代价拯救的动物叫“国家级保护”，而被摆在餐桌上的叫“家禽”。为什么?它们同样是活泼可爱的生命个体;同样是有爸爸妈妈疼爱的乖小孩;同样是被人们统称为动物。可是为什么?稀少的动物要保护，而多的却要吃掉。这边打着“保护动物”的头衔，那边却大口大口地咬着鸡鸭鱼肉。为什么那些国家级一出生就要被保护起来，过着比某些弱势群体还要舒服，而家禽一出生就是养大，等待它们的就是残忍的虐杀，然后做成各式各样的美味，被摆在餐桌上，就是为了吃它们的肉。

难道它们的生命不是生命吗?为什么要这样对待它们呢?如果有一天，换我们自己要被它们杀掉，然后做成各式各样的美味，供它们享用，我们自己的感受会是怎样的呢?

虽然我不是什么大作家，不能用很美的句子打动你们的心，但我想说的永远只有一个：同样是生命就应该受到尊重，我们没有权利决定别人的生死，饲养它们，充其量就是一个爱心的行为举动。

它们的生命也是生命，看完，请您保护您身边弱小的生命，谢谢!

Why should we protect wildlife animals?

Do you know of any endangered animals?Why are they in danger?

I think there are many endangered animals in the world,such as tigers and pandas.When farmers cut down trees,tigers can no longer hide and hunt.Many tigers are killed by people who want to sell their fur for money.And there are few places where pandas can live.We are not alone in the world.We human beings could not live without all the plants and animals around us.So protecting wildlife animals are very important.We must take measures to keep plants from being destroyed and stop animals from being killed.If each of us can plant a tree and build a birdhouse,the world will be more beautiful.It is very easy but useful.

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。

Animals Need Protecting

It is suggested that people have been aware of the issue--lack of preservation for endangered spieces, animals and plants, but as you see , they placed little efforts to cope with the problem.despite the versatility and intricacy of instruments , I would pore over some of the most striking ones and offer alternatives afterwards.

One of the major reasons , causing peoples inocence of protecting animals, is that the government did not function well as an educator, arosing peoples initiative in shielding wild animals, which led to the consequence that people do not know their responsibility to prevent animals from dangers, and specific knowledge in guarding them. what is equally important as the reason mentioned above is that media did not meet our satisfaction to inform the mass of the emergency which is crutial in arousing peoples conciousness to keep animals safe.

In spite of the serious problem, measure leading to profound improvement still can be taken. owning to the fact that funds are insufficient in some developing countries, developed countries or international organizations should shoulder more burden -- finacing them in order to capacitate them to accompolish the protection of animals. at the same time, education in telling people the way to make animals harboured ought to be focused on, thus resulting in peoples better awareness in the camouflage of our pla#from cutest creatures.

It is belived by me that if correct actions are taken to preserve animals, any kind of them will be far away from extinction forever.

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。

今天是个风和日丽的好天，我和同学贺松去了北京动物园。动物们是那么可爱，大家都非常喜欢它们。一只熊挥动着胳膊向人们要吃的，一个游客就投进去了什么东西。我想都没想就走过去说：“不要那样做。你的做法对它们没好处。如果真的喜欢它们，就应该爱护它们。”他的脸红了，并且回答说他不会再那么做了。
