The global polar bear population could decline by more than 30 percent in as little as 35 years. Thats according to a new study in The Royal Societys Biology Letters.

全球北极熊数量在35年内可能下降超过百分之30。这是根据英国皇家学会生物学快报的一项新研究。

Researchers looked at climate change effect on the Arctic Sea and calculated the likelihood of this projected population drop is 71 percent.

研究人员观察气候变化对北极海的影响，并计算出预计种群下降的可能性为百分之71。

Thats because polar bears stand on Arctic Sea ice when hunting for seals. According to NASA, even the thickest ice in the Arctic Ocean has "either thinned or melted away."

这是因为北极熊捕猎海豹时站在北极海的冰上。美国国家航空航天局表示，甚至北冰洋最厚的冰要么变薄或要么融化了。

And just this week, scientists reported sea ice levels in the area were at a record low for this time of year.

就在本周科学家报告称，该地区的海冰水平创下一年中这个时候的历史新低。

This all adds up to not great news for polar bears. With an estimated population of 26,000, the bears are already listed as a vulnerable species by the International Union for the Conservation of Nature.

这对北极熊不是什么好的消息。现估计有26,000头北极熊，已被国际自然保护联合会列为易危物种。

At present, the humanitys common mother - the earth, she for us, even his ill have no complaint, and we also - should take care of mother?

As long as you to the earth mothers blood - stream, the stream will find there are often animals such as in shat people littering caused the river smells like vomit. Another small fish and other animals in survival rates. The earth mothers bones, mountain is also at stake; Hair - woods also disastrous. Those who give loess to dig down, and then sell it to others with a high price. And the earth mother is brimming with his pain and fear his cry will cause floods. The birds in the trees are also being shot to death of the human race. Number is being with that sharp axe or chainsaw destroy forest.

Nowadays, people to see the earth mother in such pain also has the environmental protection consciousness. People slowly made public service ads, but also made environmental signs, but also on March 12 as Arbor Day. The villages have special sanitation workers.

And our students what to do to protect the environment? Actually very simple, we only need to bent down to pick up a pick up trash, pour a garbage, stop the mom and dad do not environmental protection, use less a chopsticks, etc.

We have only one earth, we need to protect our earth!

目前，人类共同的妈妈——地球，她为了我们，连自己生病了也丝毫不控诉，而我们也—应该关爱妈妈吧?

只要你到地球妈妈的血液——小河、小溪等就会发现经常有动物在排泄粪便，人们乱扔垃圾造成河水让人闻起来就想吐。另外小鱼等动物骤降存活几率。地球妈妈的骨头——山峰也危在旦夕;头发——树林也损失惨重。那些人把黄土给挖下来，然后再用高价卖给别人。而地球妈妈正强忍着自己的痛苦身怕自己哭泣会造成洪灾。树林中的小鸟也正在被人类的枪给打死。数目正在被人吗用那锋利的斧头或电锯破坏树林。

如今，人们看到地球妈妈这么痛苦也有了环保意识。人们慢慢地做出了公益广告，还做出了环保标语，而且还吧3月12日定为了植树节。各村都有专门的环卫工人。

而我们小学生该做什么才能保护环境呢?其实十分简单，我们只需要弯腰捡一捡垃圾，倒一倒垃圾，阻止爸爸妈妈做不环保的事情，少用一次型筷子等。

我们只有一个地球，我们要保护我们的地球!

I love small animals very much, but my favorite is the puppy.

The puppy is not big, but the head is big. There is a pair of small triangular ears, faces are small. A pair of gem-like flexible and translucent big eyes, a round yo black nose. The body of the hair was yellow, smooth like painted a layer of oil. Tail hairy, often swing to swing, feels very comfortable.

Puppy eating food will be issued a little sound, eat quickly, it seems hungry look. Sleep when motionless, very quiet, a movement to lift his head to see, nothing to keep lying on the ground to sleep. When you play the game, if you are happy, will be hard to put the tail, jumping to the distance, the tongue often stretched out.

Because my neighbor has a puppy, so I often play with it. Puppys head is big, I called it "big head". Once, I just returned to the door, see the dog playing on the roadside, running around. I was ready to open the door, the dog immediately ran over, shook his head in front of me, as if very welcome me.

I really like this lovely and naughty puppy! I believe you will like this "big head" it!

My favorite little animal - puppy.

Several problems are caused by the non-organic substance. We ought not to pour wastes into the ocean, because it not only pollutes the ocean, but also lead to a series of harmful consequence. First and foremost, the non-organnic things, for instance, plastic bags, may kill fish and whales. Second, fishes cant digest them. Finally, some of the rubbish is inherently toxic, they will posion marine life.

We must take actions to protect our whale from dying. One thing we should do is creating a better system of disposing of rubbish. Another effective solution is making ships environmentally friendly. Sypermarkets shall stop the giving of plastic bags.

As a captain of the ship, you should spare no efforts to think more helpful ideas and stop dumping rubbish from now on. We all need to raise awareness of these problems. It now becomes necessary that we must act now, before it is too late!

今天的班会课是保护动物课，由一位大哥哥和三位大姐姐和刘璟璇的妈妈给我们上课，讲的是保护朱鹮的课，我们还看了一下假朱鹮，还看了朱鹮的飞翔的照片，我知道了，朱鹮飞翔的时候翅膀的的颜色是橘色的，还看了在春天和秋天朱鹮的照片，为什么朱鹮在春天的颜色是黑色的呢？把我们都惊呆了，我们在地下都讨论着，为什么春天朱鹮是黑色的呢？

最后还是被我猜对了，其实是要保护它的小宝宝，所以他才这样的，最后下课了，哥哥姐姐们给我们发了一包奖品，我打开一看，有两根铅笔、一个卷笔刀、一个小橡皮、还有一个画画本还让我们折了朱鹮下个礼拜姐姐们给我们把折好的朱鹮送给我们，我们非常开心，所以我们要好好学习，天天向上。

每一个人都有责任保护环境！爱护动物!亲近自然！这是我们要做的，也是必须做的。你知道吗？环境现在受的威胁，而威胁的人就是那些不爱护环境的人，你知道不爱护环境对地球有多大危害。土地沙漠化，空气受到污染，无法抵抗沙尘暴，影响人们的身体健康等等。这是我们想要的结果吗？对!不是。每一个人都想在一个良好的的环境里学习，工作，休息。谁都不想在一个环境受到污染的地方。人类是花的根，环境是未绽的花苞，根努力就能开出美丽，反之只有枯竭、谢落。所以要保护环境，这也是在保护我们正受威胁的地球！

爱护动物也是必须做的。有的一些可怜的动物，就是因为人们不停地残杀，就快绝种了。有的是已经绝种了。就说那可怜的渡渡鸟，已经绝种了，他/她们是多么的可爱！

我为此发出倡议：1不要在伤害那些无辜，可怜的动物，它们也有生命。2大家互相监督，坚决不杀动物吃。3一起提倡爱护动物，大家一起携手保护动物。希望大家一起爱护动物。

亲近自然。多去户外走一走，多与大自然接触，与大自然一起玩，大自然会喜欢你，你也会更喜欢大自然。

总之一句话：“保护环境！爱护动物！亲近自然！”

[保护环境 爱护动物 亲近自然的作文

Life, environmental pollution continuously affects our lives. Such as: polluted air, rivers and garbage pollution, etc., has seriously damaged our living environment.

Rivers are polluted, the creature will not be able to survive in the water, also cant use it to irrigate crops, the human will not eat fresh food. If same, groundwater contamination, people will drink less than clean water, humans will get sick, poisoning, and it may even die. So, no one should be put on the possible environmental pollution of waste into the river.

Air is a guarantee to the survival of all living creatures. If the air is polluted, all creatures will live in the "gas", disease and all kinds of disasters will be the humanitys greatest enemy. Last, mankind will perish. Visible, clean air is how important!

Garbage can be seen everywhere in our daily life, the visible human bad habits - littering behavior is really too serious. Random pile up garbage can cause great harm to the environment, such as: air pollution in a breeding ground for germs, sexually transmitted diseases, and river and so on.

The pollution was terrible! To prevent the pollution, we must care for the environment, protect the earth, to stop all the pollution of the environment.

生活中，环境污染不断地影响着我们的生活。比如：被污染的空气、河流和垃圾污染等等，已经严重地破坏了我们的生活环境。

河流被污染了，水中的生物将无法生存，也不能用它浇灌庄稼，人类将吃不到新鲜的食物。同样，地下水如果被污染，人们将喝不到洁净的水，人类将会生病、中毒，甚至可能会死亡。所以，任何人都不应该往河里投放有可能污染环境的废弃物。

空气是所有生物赖以生存的保证。如果空气被污染了，所有生物将会生活在“毒气室”一样的环境里，疾病和各种灾难将会是人类最大的敌人。日久天长，人类就会灭亡。可见，洁净的空气是多么重要啊!

垃圾在生活中随处可见，可见人类的坏习惯——乱丢垃圾的行为实在太严重了。随意堆放的垃圾会对环境造成很大的危害，例如：滋生病菌、传播疾病、污染空气以及河流等等。

这些污染真是可怕呀!要预防这些污染，我们一定要爱护环境，保护地球，制止一切污染环境的行为。

你相信吗,一只海豚竟然让一个聋哑人恢复听力和说话能力。

今天，我在《中国少年报》里看见了一则新闻，一只海豚让一个聋哑人恢复听力和说话能力。而那只海豚的父母和族群却被人们无情的杀害了。只有它和一只幼豚侥幸逃脱。而那只幼豚在逃脱时也受了重伤，没过几天就不幸死亡。

本来一个好好的族群就只剩下它一个了。也不知它是怎么度过这漫长而又痛苦的日子。但它没有嫉恨人类，而且还帮一个聋哑人恢复听力和说话能力。而我们人类却捕杀动物或乱摘植物。动物、植物是我们最好的朋友，要是我们人类没有它们，我们人类也将难以生存。它们和我们息息相关，它们需要我们的爱护和帮助，而我们也需要他们的帮助，我们怎么可以乱捕杀动物和摘采植物呢，我们一定要爱护它们。

动物能不记前嫌，为什么我们人类就不行吗?有些自私的人，只为自己着想，去偷猎那些稀有的动物，乱砍伐森林。有些人觉得植物非常低贱，看见不绕道走，而且还践踏植物。他们只为自己着想，要是我们全世界的人们都像这些人一样，我们迟早也要灭绝。因为植物能进行光合作用制造有机物和氧气，为我们提供食物和新鲜空气，没有了食物和新鲜空气，人类又将如何生存呢!

我们有些人总是一点点小事也耿耿于怀。记得去年，我看见了一则新闻，是关于一个人为了一元钱而杀死一个人。难道这样值得吗?难道我们连动物都不如吗?难道我们不能不那么斤斤计较吗?难道我们不能心胸宽阔点吗?

Animals are our best friends. But there are many bad things about them. So we should try our best to protect animals.

First, let us know the status of the animal. Now, animals are facing very great danger. For example, there are many kinds of animals will die out. And there are many people eat precious and wild animals. They are nasty. As students, we should stop this behavior and protect animals.

Then, let us know we should how to protect animals. We should protect they habitat. If you see other people mindlessly trample animal homes, nicely remind them of the damage theyre causing. We can not also eat some wild animals. We should ask other people to protect them, too. Let we protect animals together!

Animals are friends of human beings. An animal is dependent on the human, also, the human also cannot leave the animals.

Long, long ago, animals and humans are a good friend. They help each other, rely on each other, get along with, who also cannot leave the who. However, with the passage of time, because of human beings, the animals with human relations soured, and there are more and more serious trend.

First of all, human beings to animals is wanton killing, on the one hand, caused a substantial reduction in animals, on the other hand also caused the animals to human hostile, to some extent destroy the animals with human friendly relationship. In fact, for a long time, the behavior of the human animal cruelty has not rested, eat eat peacock, owls, monkey, red-crowned cranes, bear bile absorption, is really to the point of "all things" entrance! What do you want to, so can not cause animal angry? How can you make animals not to stand up and fought back? This is also the animal attack humans, even damage the important reason of human life.

Second, with the progress of human society, some bad behaviors of human beings, not only destroyed the earths environment, and damage to the animals living environment. Factory sewage, automobile exhaust, deforestation of forests and other bad behavior, have caused serious damage to nature, and at the same time there are opposite to the nature of the direct damage caused by animals that makes the animal difficult to live, the type and quantity less and less, destroy the balance of the ecosystem, eventually make human to destruction.

Visible, the relationship between animals and humans have come to the point where serious deterioration, at the same time, also pose a threat to the survival of mankind itself. Humans are still can such wrong-headed, impenitence? ! I think that human beings should be timely change their bad habits, to love animals, protect earths environment.

As a primary school student, we should start from me, start from now, to take care of our nature, protect the animals around us.

Let us act together, take care of animals, people for the ethical treatment of animals, and become a good friend of animals, to improve the relationship between the animals and humans to make their due contribution!

动物是人类的朋友。动物离不开人类，同样，人类也离不开动物。

很久很久以前，动物和人类是一对好朋友。他们互相帮助、互相依靠、和睦相处，谁也离不开谁。但是，随着时间的推移，由于人类自身的原因，造成了动物与人类的关系恶化，而且有越来越严重的趋势。

首先，人类对动物的肆意捕杀，一方面造成了动物的大量减少，另一方面也造成了动物对人类的敌意不断增强，一定程度上破坏了动物与人类的友好关系。事实上，一直以来，人类残害动物的行为一直没有停息过，吃孔雀、吃猫头鹰、吃猴脑、吃丹顶鹤、吸熊胆，真是到了“万物皆入口”的地步!您想，这样怎么能不引起动物的愤怒呢?怎么能让动物不挺身而出、奋起反击呢?这也是造成了动物攻击人类、甚至伤害人类生命的重要原因。

其次，随着人类社会的不断进步，人类自身的一些不良行为，不仅破坏了地球环境，也破坏到了动物的生存环境。工厂的污水、汽车的尾气、对森林的过度砍伐等不良行为，都对大自然造成了严重的破坏，同时也对生存在大自然的动物造成了直接的伤害，使动物生存艰难，种类、数量越来越少，破坏了整个生态系统的平衡，最终使人类走向灭亡。

可见，动物与人类的关系已经到了严重恶化的地步，同时，也威胁到了人类自身的生存。人类难道还能这样执迷不悟、不知悔改吗?!我想，人类应该及时改变自身的不良习惯，爱护动物，保护地球环境。

作为一名小学生，我们应该从我做起，从现在做起，爱护我们的大自然，保护我们周围的动物。

让我们大家一起行动起来，爱护动物，善待动物，成为动物的好朋友，为改善动物与人类的关系做出自己应有的贡献吧!

Dogs are passionate, friendly and the most important of all, faithful. Many people view dogs as their life-time friends or even partner. However, not every people know How to protect them. In this essay, I will introduce to you specifically about how to protect dogs.Sometimes dogs are brave defenders of our livestock, whereas sometimes they are as fragile as we are. Dogs should not be feed with salt, otherwise they will suffer from a hair loss. You need totake your dog out for a walk once in the morning and once in the afternoon to make sure it is having a healthy life. Dogs need to take regular check-ups as well, in case it is infected.There is a popular saying goes, "you may have many pets in your life, but your pets just have you in his life", which has moved many people. Please take good care of your dear pets. Their destinies are completely on your hands.

[保护流浪狗英语作文

可能我们没有察觉身边的动物在一天天地减少。动物是我们人类的好朋友，我们都要保护它们。

有一次，我看到一个悲惨的场面。那天，我在树下玩，无意中看到了几个小孩子正搭着梯子去掏鸟巢。他们把小鸟的雏儿放在射板上，用箭将雏儿活活射死。雏儿身上流着一滴滴鲜红的血。而那些小孩却在哈哈大笑，毫无悔改之意。

在我们学习过的一篇课文里，羚羊们为了生存，老羚羊不惜牺牲自己的生命，让年轻羚羊踩在它们的背上跳过悬崖。我的心被这群动物的举动深深地震撼了。而所有这一切都是我们人类造成的，因此在此我提议：

1.不要猎杀动物、鸟类，不乱提动物进行贩卖活动。

2. 不要乱砍伐树木，不破坏鸟的家，不掏小鸟。

我们要号召人类保护动物，不要为了个人的利益去滥杀无辜。否则，最后灭亡的将是我们人类自己。让我们从现在开始“敬畏生命，善待动物”吧！

信赖，往往创造出美好的境界。

我曾经在报纸上看到过这样一幕：猎人把枪对准了一只正在给孩子喂奶的母猴，母猴看到后惊慌失措，立马把小猴放下来，自己从树上跳下来，然后对着猎人拍了拍自己的胸脯。意思是让猎人有什么事冲着自己来。请问，如果你是猎人，看到这一幕，你还会舍得开枪吗?

人类真的太聪明了，聪明到有点可怕。人类不仅会利用自己的感情，还会利用动物的感情，利用动物对自己的信赖。

一群猎杀队在非洲大草原上看中了一头品相很好、象牙很大的大象。

但是这头大象对猎队的人一直警惕，一直躲躲藏藏。猎杀队的人为了跟大象拉好关系然后把它杀死，他们就驻扎在草原里，每天都在草原里吃在草原里睡。

就这样过了一个星期，大象逐渐对他们放松了警惕。在猎杀队没水喝的时候大象带着猎杀队找到了河水，救了他们一命，善良可爱的大象还到带着猎杀队的人认识了自己的七个小伙伴……

又过了半个月，大象对猎杀队产生了信赖。直到有一天，猎杀队的人借用要去喝水的理由把大象引到了一个他们早已设好的陷阱里……

猎杀队的人没有良心。他们觉得拔象牙时，象牙长得太深难拔，于是他们就把大象脸上的肉刮干净然后继续拔牙。他们觉得只拔大象的牙有点浪费，于是他们就把大象的鼻子和四肢都砍了下来。他们又想起了大象的另外七只伙伴，于是他们也用相同的方式把其他七只给杀了……

是的，最后满载而归，如果不被抓，他们肯定能赚一大笔钱。但是，我想问，他们的良心真的不会痛吗?我真的很难想象那头大象被杀时的心情。

没有买卖就没有伤害。我们不能控制动物的行为，但是我们可以不买它!抵制野生动物产品!我希望人类和动物能和平共处!

Today, Dameisha took me to see the sea, because I have never seen the sea. I was thinking of the sea all the way. I saw on TV the sea is very beautiful, I feel that the sea should be like this: blue water, spray gently lying in the arms of the sea. On the beach there grows many palm beach, lying quietly in many shells, conch. A few crabs to climb. Should be against the background of blue sky, the sky the sun, seagulls flying, this beautiful picture of you! What an intoxicated! I feel relaxed and happy.

Can be when I saw the sea of a moment, I am disappointed, the mood suddenly changed. Because my eyes of the sea is dark, is muddy, is not angry, is not confident. Some just inferiority. I know that the sea is not so, but people are polluting into this.

Now, human beings in order to live, a large number of cutting trees, cut and not planted, how many of the previous tropical rain forest, now is flat, how many trees, now replaced by high-rise buildings. Factory emissions, air pollution, and no trees to release fresh air. And plant emissions of toxic wastewater, so that water in the small fish, shrimp have been poisoned, and the river afloat smelly fish dead bodies and garbage, all this is how terrible ah!

Lets go and embrace the nature! To protect nature! Let everything in the world be beautiful.

今天，大姨带我去大梅沙看大海，因为我从来没有见过大海。我一路上都在想大海的样子。我看见电视上的大海很漂亮，我觉得大海应该是这样的：碧蓝的海水，浪花轻轻的躺在大海的怀抱中。海滩上生长着许多的椰树，海边静静的躺着许多贝壳，海螺。几只螃蟹爬来爬去。映衬着的应该是蔚蓝的天空，天空上的一轮红日，海欧飞来飞去，这景象多美呀！多令人陶醉呀！我心情轻松愉快。

可当我才看见大海的一瞬间，我失望了，心情一下子变的沉重了。因为我眼前的大海是灰暗的，是浑浊的，是没有生气的，是没有自信的。有的只是自卑。我知道大海原来不是这样的，而是被人们污染成这样的。

现在，人类为了生活，大量砍伐树木，砍了又不栽，以前有多少热带雨林，现在是平地，以前多少树木，现在取而代之的是高楼大厦。工厂排放的废气，污染空气，又没有树木放出新鲜的空气。还有工厂排放出的有毒的废水，让水里的小鱼，小虾都被毒死了，河面上浮着发臭的鱼的尸体和垃圾，这一切又是多么的可怕呀！

让我们去拥抱大自然吧！去保护大自然吧！让世界上的一切都变得美好。

The quality of human life has improved greatly over the past few centuries, but Earth is being harmed more and more by human activity. As we develop our technology, we demand more from our planet. Eventually, this will harm people as well.

Our planet gives us everything we need, but natural resources are not endless. Strip mining devastates whole regions, leaving bare and useless ground. Deforestation removes old growth trees that cant be replaced. Too much fishing may harm fish populations to the point where they cant recover. We are too careless in taking what we want without giving anything back.

There are more people than ever, living longer that ever. So is it any surprise that many areas suffer from too much development? Anyone living in or near a city has experienced "urban sprawl". There is a new shopping area on every corner and new houses, townhouses and apartments everywhere. Traffic gets worse and worse because planners cant keep up with growth. Keeping up with human demand is hard enough. Environmental concerns come in last.

With growth comes pollution. Companies and communities dump waste into water. Landfills are full of trash. Emissions from factories pollute the air. Barrels of industrial waste and worse, radioactive waste, have no safe place to go. If were not careful, we can harm our planet beyond repair.

People need to respect the Earth and try to preserve it. If we dont, what kind of future will we have?

To Whom It May Concern,

I am writing to express my opinion about the current policy on the official holidays, such as Spring Festival and Golden Week Holiday. As you might know, some believe it is a good idea to enjoy a week-long break. For one thing, it provides enough time for people to refresh their minds and thus to have better preparations for their future work. For another, it will lead to increased tourism and in turn stimulate the development of the local economy.

Truly, the past decade has witnessed many advantages of the official holidays, but we should never ignore its disadvantages. On the one hand, it may lead to heavy traffic in that a large number of tourists go on traveling during the same Period, thus, it might cause air pollution. On the other hand, some tourists, with no awareness of environmental protection, often drop litter at random so that the scenic spots are polluted and thus it demands a tremendous sum of money to eliminate the pollution.

Considering the current grim situation, it is necessary that the authorities concerned should take immediate measures to eliminate these disadvantages. Only through these efforts can we relieve the traffic pressure and at the same time raise people’s awareness of environmental protection.

Yours sincerely,

So how can polar bears thrive on their version, seal blubber?

那么,北极熊是如何处理这些高热量食物的呢?

Turns out theyve stocked up on genes that let them clear fats from their blood.

结果显示它们储存在遗传基因里的信息使得它们能够清除血脂。

Thats according to a study in the journal Cell.

这是根据《细胞》杂志上的一篇研究得出的结论。

Polar bears are well adapted to life on the sea ice.

北极熊非常适应在浮冰上的生活。

Up to half their body weights fat, which gives them extra insulation and buoyancy, and provides them with a ready source of energy.

几乎占它们身重一半的脂肪足以使它们保暖并且维持体力，提供给它们一种易转化的能量。

But how can an animal so fat also be so fit?

但一种动物怎么能又胖又健康?

Researchers compared the genomes of polar bears with those of brown bears, and found that polar bears have accumulated genetic changes that boost their heart health and fat metabolism.

研究人员们通过比较北极熊和棕熊的基因，发现北极熊的基因组中积累了不少有利于心脏健康和脂肪代谢的遗传突变。

One gene in particular, called ApoB, helps move cholesterol out of the blood—where it causes problems in humans—and into cells.

特别是编码为载脂蛋白B的基因有助于清除血液中对人类有害的胆固醇转变成细胞代谢。

These genomic changes happened quickly, evolutionarily speaking.

这些遗传变化从进化的角度来讲发生的十分快。

Polar bears and brown bears diverged from a common ancestor less than half a million years ago.

北极熊和棕熊都来自于同一个祖先，它们是在大约50万年前左右开始向不同分支进化。

But if that seems super speedy, the ability to digest lactose didnt spread through human populations until we domesticated cows, just 10,000 years ago.

但是如果这种变化看上去十分快速的话，消化乳糖的酶逐渐进化到人类各个种群中也还是发生在大概1万年前我们可以驯化乳牛之后。

A moooving testament to the power of natural selection.

这是自然选择力量的证明。

One Sunday afternoon, I casually adjust the TV channel. All of a sudden, disastrous scene into my line of sight: a peasant who was holding a piece of iron hammer, turned out to be a butcher is a not how big head of pig slaughter.

I saw all this. Found that pigs fate was so miserable! Is this fate arranged? Or pigs caused by past delicious lazy? I found the "people" are so cruel. Oneself have so long pig, cruel to kill it. Ah, I found that at the moment I was so sad, so sad, so lost, so helpless. In nature there are many more miserable than this things are happening, perhaps this is fate, it is inevitable in the growing of a test.

Not often say that animals are friends of human beings? Not often say that people for the ethical treatment of animals, protect the earth? Maybe this is just for those rare animals! Those animals that almost nearly perish! Pigs in a country of the world, one city, a town, a village, or even a home, a person can see. Pigs are a lot of, is not worth to treat? Pig also is to have life, and human beings, it also know pain, also have feelings, also know how sad. People for the ethical treatment of animals! The animals as their friends, for they give a little love!

Animals are friends of human beings, like humans, are the people of the earth. Let us hands reach out, to protect, to help those who need help human friends!

一个周日的下午，我漫不经心地调着电视频道。突然，惨不忍睹的一幕进入我的视线：一个农民模样的人正拿着一根铁棍敲打什么，原来是一群屠夫正在屠杀一头不怎么大的小猪。

我亲眼目睹了这一切。发现猪的命运竟是这么悲惨!难道这是命运安排好的吗?还是猪前世的好吃懒惰造成的?我发现“人”竟是那么狠心。自己养了这么长时间的猪，竟然狠心杀掉它。哎，我发现此刻自己竟是那么的伤心，那么的悲痛，那么的迷惘，那么的无奈。大自然中还有很多比这更悲惨的事情正在发生，或许这就是命运，这就是在成长中不可避免的一次考试。

不是常说动物是人类的朋友吗?不是常说善待动物，保护地球的吗?可能这只是针对那些稀有的动物罢了!那些几乎将近灭亡的动物罢了!猪在世界的某个国家，某个城市，某个城镇，某个村庄，甚至某家某户都可以见到。猪是很多，多到不值得善待?猪也是有生命的，和人类一样，它也知道痛，也有感情，也懂得伤心。善待动物吧!把动物当成自己朋友，对它们付出一点爱吧!

动物是人类的朋友，同人类一样，都是地球的子民。让我们伸出双手，去保护，去帮助那些需要帮助的人类的朋友吧!

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。
