Animals are mans most loyal friend, please dont hurt them.

I am particularly fond of small animals,. I think, they are mans most loyal friend. So, when I see others to dispose of animals, in the heart can not help but sad. My dream is to people and animals live in peace.

Now people are like to eat dog meat hot pot, I dont understand. A dogs life, it is to his own master, dont just because it is old, useless, and denied the value of its existence. This is not possible! People will also newborn puppies thrown into the lake, trash can, they are discarded, it is no good. Everyone has the right to existence significance and value, even if is a person, also not qualified to deprive their lives.

I have witnessed the cat after being hit by a car fly. The distorted face telling the pain of it. Its blood, viscera was hit from in vitro. Although the rain wash away the traces of blood, but every time I go there, mind will automatically jump out of the scene, think of the cat that broken beyond recognition, think about it before he died not look in the eyes...

Since then, I was in my heart silently vowed, to do their own efforts, to protect small animals, at least, dont let them innocent caused the death.

I think, in the future, I will set up a "happy family", there will be dedicated to adopt the stray animals, if the man willing to adopt, I will also be given to him. In this way, those who stray cat, stray dogs have a warm home. I will also for those precious endangered animal donations, not completely destroy them.

Perhaps, so I am very silly, very silly, but I am willing to do that silly to worry about in others eyes puny little animals.

If you also like me "stupid", let us firmly "silly". Because they are lovely.

动物是人类最忠诚的朋友，请不要伤害他们。

从小，我就特别喜欢小动物。我觉得，它们是人类最忠实的朋友。所以，当我看到别人随意抛弃动物时，心中不禁很难过。我的梦想就是人们和动物和平相处。

现在人们都很喜欢吃狗肉火锅，我很不理解。狗的一生，都是为了自己的主人，难道就只是因为它老了，不中用了，就否定它存在的价值。这是不可以的!人们还将刚出生的小狗崽扔到湖里、垃圾桶里，将它们随意丢弃，这也是不行的。每个人都有存在的意义和价值，即使是人，也没有资格剥夺它们的生命。

我曾经亲眼目睹了猫被车撞飞后的惨状。那扭曲的脸诉说着它的痛苦。它的鲜血、内脏被撞离体外。尽管雨水冲刷掉血的痕迹，但每当我走到那儿时，脑海就自动地跳出了那一幕，想起那只被撞得面目全非的猫，想起它死前不甘的眼神……

从那时起，我就在心里默默发誓，要尽自己的努力，来保护小动物，至少，也不会让它们无辜枉死。

我想，在将来，我会成立一个“幸福之家”，这里会专门收养流浪小动物，如果好心人愿意收养，我也会赠送给他。这样，那些流浪猫儿、流浪狗儿就有了一个温暖的家。我也会为那些珍贵的濒临灭绝的动物捐款，让它们不至于完全灭绝。

或许，这样的我很傻、很傻，但我愿意做那个傻傻的为在别人眼里微不足道的小动物担心的人。

如果你也像我一样“傻”，那让我们坚定不移地“傻”下去。因为它们都是可爱的。

Dog is my favorite animal. The reason why I like it most is because it’s very competent. Dog is the best friend for mankind. It is also the best companion for the old people. The dog can feel the human nature. So many old people will raise dogs if their children are not with them. The old can give their love for their children to the dog to make themselves feel warmly. I believe the seeing eye dog is very famous. They are special dogs. Those dogs will guide their owners whose eyes is blind to go the correct way. See, I say dogs are very competent.

我最喜欢的动物是狗。我最喜欢它的原因是因为它很能干。狗是人类最好的朋友。它也是老人们最好的伴侣。狗是通人性的。如果他们的孩子不在他们身边，很多老年人会养狗。老年人可以把对他们孩子的爱放到狗狗的身上，这也能温暖他们的心。导盲犬是非常有名的。他们是特殊的狗。这些狗会引导眼睛看不见的主人找到正确的路。看，我就说狗狗是非常能干的。

Second， we should save energy， such as less turning on the lights and turning off the lights when we leave;Do more walking， more bicycling and less driving and so on. Third， we should ask our government to control the pollution from the factories.

Let’s act now from everything to save our environment. Don’t let our tears be the last drop of water in the world!

让我们做些事情来拯救我们的环境

这是最近报道，一些河流和湖泊已经干涸的中国南方地区。许多鱼死了。河流和湖泊的底部变成了草地。由于天气不好，水变得越来越少了。

所以每个人都应该做些事情来拯救我们的环境。首先，我们应该节约每一滴水，如使用后关闭水龙头和回收水。例如，我们可以用我们用过的水给植物浇水和打扫休息室。第二，我们应该节约能源，比如我们离开时少开灯和关灯;多走路，多骑车，少开车等等。第三，我们应该要求政府控制工厂的污染。

让我们从一切行动来拯救我们的环境。不要让我们的眼泪成为世界上最后一滴水!

We need to protect small animals, especially chickens this kind of small animals, because chickens can call in the morning we wake up, can have another round of eggs, chicken can also provide for us.

On one occasion, my mother and I serving market, hear an old woman Shouting: "chicken, chicken fat and tender today!" Mother said: "today, we buy a chicken home, stew to drink." I said: "ok." But wanted to think: if we ate chicken, then you cant eat eggs, he said to mother: "no, eat the chicken, there is no egg." "The silly child, you fuck what blind heart!" Mother threw themselves to pull me to the other side of the chicken. Granny is kill chicken chicken, she plucked chickens neck hair, the knife in chicken neck hard a few strokes. Chicken blood spray to the surrounding, struggled for a few times and he died. "So cruel, I dont want to eat chicken!" My mother to protest loudly. "Well, dont buy, we will go to buy some vegetables." Maybe my mother also feel cruel, agreed.

If our life does not have the animal, the world will become very lonely. , we need to protect animals from oneself: eat less meat, less wear leather sweater; See someone humiliate animal, to bravely to come forward to persuade them.

To protect animals, everyone duty!

我们要保护小动物，特别是小鸡这类弱小的动物，因为小鸡早晨可以叫我们起床，可以生一个又一个圆圆的的鸡蛋，还可以提供鸡肉给我们吃。

有一次，我和妈妈上菜市场，听见一位老奶奶在喊：“卖鸡了，今天的鸡又肥又嫩!”妈妈说：“今天，我们买一只鸡回家，炖汤喝。”我说：“好吧。”可又想了想：如果我们吃了鸡，那么就吃不到鸡蛋了，就对妈妈说：“不行，吃了鸡就没有鸡蛋吃了。”“傻孩子，你瞎操什么心啊!”妈妈不由分说地把我拉到卖鸡的那边。卖鸡的老奶奶正在杀鸡，只见她拔下鸡脖子上的毛，拿刀用力地在鸡脖子上划了几下。血喷向了四周，鸡挣扎了几下就死了。“太残忍了，我不要吃鸡!”我向妈妈大声的抗议。“好吧，不买了，我们就去买点蔬菜吧。”也许妈妈也觉得残忍，就同意了。

假如我们的生活中没有了动物，世界就会变得很孤独。我们要保护动物，从自身做起：少吃肉类食品，少穿皮衣毛衣;看见别人欺负动物，要勇敢地站出来劝说他们。

保护动物，人人有责!

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.

Animals are our humans good friends, we cant hurt them, but some people are for your own sake, regardless of the poor little animals life and to trample them, kill them.

Remember that is one day this summer, I chat with grandma sitting on one side of the road, I saw a cat wanted to cross the street opposite of a piece of meat to eat, who knows, the cat just walked to the middle of the road, a large truck, the driver while riding on the horn, mouth scold a way: "dead cat to go away." Kitten also dont understand the meaning of the driver, the driver has been impatient, he put the pedal to a a small life is so dead in the wheel of a large truck full of cargo.

Let every man in the world to protect small animals.

Im looking forward to this holiday was born at an early date.

动物是我们人类的好朋友，我们不能伤害它们，但有些人却为了自已的利益，不顾那些可怜的小动物的生命，去践踏它们，捕杀它们。

记得那是今年暑假的一天，我和姥姥在公路的一边坐着聊天，我看见一只小猫想穿过马路去吃对面的一块肉，谁知，小猫刚走到马路中间，一辆大卡车过来了，司机先生一边按喇叭，一边嘴里骂道：“死猫走开。”小猫还没理解了司机的意思，司机先生已不耐烦了，他一踩油门，一个小生命就这样死在了满载货物的大卡车的车轮下。我看着这一幕又气愤又伤心，为了纪念这只可怜的小猫，所以我想把这一天——7月2日设立为保护动物节。

到了每年的这一天，人们都要为保护动物做贡献，要让小动物轻松愉快地度过这一天，不能让它们受到伤害，小动物不管到了谁家，人们都要热情招待它们，最后，我们还要用各种不同的方式去宣传小动物对人类的帮助。让世界上的每一个人都要保护小动物。

我盼望这个节日早日诞生。

我最喜欢的小动物是小鸡。

My favorite little animal is chicken.

恰好，我家楼下307号就养了几只小鸡。每天我们经过时，这些小鸡都偏着脑袋看我们哩。

Just right, my house downstairs 307, raised a few chickens. Every day we pass by, the chicks lean on our heads.

小鸡全身毛茸茸的，很可爱。一身黄黄的羽毛像披着一件金黄的礼服。小鸡有一双尖尖的小嘴。圆圆的眼睛看人时还蛮有精神的呢。

The chickens are hairy and lovely. A yellow feather like wrapped in a golden dress. The chicken has a pair of pointed little mouth. The round eyes are quite spiritual when they look at people.

我没看到它们的耳朵，但是小鸡不可能没有耳朵。如果没有耳朵的话，那我们走过去时，它们怎么会偏着脑袋朝我们瞧呢?

I dont see their ears, but chickens cant have ears. If there were no ears, how could they lean on our heads when we walked by?

妈妈说，刚孵出的小鸡还只能吃小米粒，不能吃谷子或玉米，还要经常给它们喝水。要是有小虫子给它们吃，它们一定会长得更神气。

Mother said, the newly hatched chickens can only eat small grains of rice, can not eat millet or corn, but also often give them water. If they had worms, they would have grown stronger.

我多喜欢这些可爱的小鸡呀。但是爸爸妈妈说现在还不能养，不养好的话，它们会死的。

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.

在台湾,因为大多数人不了解野生动物的重要性,野生动物是在一个贫穷的情况下。我们中国人喜欢吃什么美味,所以有许多动物被猎人杀害。人们喜欢吃老虎,熊,鸟,和狮子,所以有越来越少的鸟在天上飞,越来越少的熊在森林里到处跑。相反,我们经常看到他们在市场出售。他们是多么可怜!我们是多么残酷!

在我看来,我们应该尝试每个可能的方法来保护野生动物。首先,没有人可以伤害任何野生动物。其次,有关当局应该惩罚那些杀害野生动物。第三,我们应该多注意那些濒危物种保护其不被吃掉。如果我们能这样做,自然必须变得非常漂亮。

Animal Farm tells a story that one day the animals overthrow the farmer Mr. Jones, and found their own regime, called Animal Farm They adopt Seven Commandments of Animalism, of which the most important is All animals are equal。 Pigs are the leaders of the operation of the newly start-up farm.Thanks to the right lead of the pigs and selfless and hardworking of all animals, the Animal Farm develops good enough to their demands.

However, the leaders separate into two factions soon after. As a result, Snowball is expelled by Napoleon as a betrayer. Although many animals remember that Snowball is a brave leader, they firmly believe they were wrong and Snowball is a bad animal indeed after brainwashing Napoleon offered. What’s more, the Seven Commandments of Animalism had also been changed. Finally, the Animal Farm becomes quite different from what they hope it to be at the beginning.

From the novel; I expressively feel the great power of faith. With the faith of Animalism, they finally found their regime, and struggle the equal from humans. And because of the faith, Napoleon can still rule the wretched animals, even though Snowball has gone. In our daily life, faith is indispensable as well. Faith just as flame, guiding us and supporting us when we feel frustrated as well as every time we need power to keep going ahead. When the Animal Farm is in mess, the animals still believe in their faith and Animalism. As to us, this believing is needed. Sometimes we may think we are in a wrong road to our dream, or we lose heart of ourselves, considering we aren"t as well as respect, we need believe. A b faith just likes a protection, and we are protected by it from kinds of difficulties.

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。

Animals Need Protecting

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 careBecause 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. WhyBecause 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.

动物需要保护

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。

This is the composition about to protect and love our environment. Indeed, we only have one earth, it is essential and imperative for us to treat it nicely. Or else, we will be the one suffering. As a matter of fact, a great number of animals and plants had extinct. All this was substantially because of we human being. And a large number of them are endangered. If this does not imply that we are not obliged to do something, the world is going insane and will be destroyed. To stop this from happening, we have many options. First and foremost we should start from ourselves. Do as what a perfect citizen should do. Then, restrain the factories from polluting, this can be done by establishing laws and rules. If we united as one, nothing is impossible.

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。

The little Rabbit has a coat of white hair.The two ears are long and prick up on its head.

It is furry,soft and white with two red eyes glaring above the chin.

Its eyes are like a pair of small red hulbs.

Exposed to sunlight,they become little pieces of red thread.

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.
