关于保护动物的英语作文翻译中文（精品20篇）

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.

许多野生动物正面临绝种的危险，因为它们生活的环境发生了极大的变化。例如，随着城市的发展，杀虫剂的使用和严重的污染，他们的生活区域变得越来越狭小。许多野生动物，现在面临粮食危机。同时，人类正在屠杀野生动物只是为了获得它们的皮毛，皮肤，角，牙齿和肉。

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.

为了保护生态资源，人们应该意识到任何物种的缺失，至少意味着知识资源和自然美的缺失。因此，本应采取以下措施：制订污染标准以降低有毒物质;严禁杀害某些稀有物种;应建立国家公园作为野生动物，保护区。

Only if we human beings take some drastic measures can wild animals be preserved.

我们只有采取一些有力措施，才能保护野生动物。

He comes home, has a shower,

And eats dinner, every day.

Now he’s sitting in his favourite chair

Too tired to laugh or play.

He reads his book or newspaper

To learn what’s new today.

Soon he’ll go to bed.

He’s a boring man, my dad.

Then I see him working,

On the building site.

He’s high up in the clouds

Higher than a kite

He’s walking on a narrow piece of wood

Not worried about the height,

Not afraid, not afraid like me.

He’s a superman, my dad.

他每天回到家，洗个澡，

吃晚饭。

现在他坐在他最喜欢的椅子上

太累了不笑也不玩。

他读书或者看报

了解今天又什么新的消息。

一会儿他就上床睡觉。

我的爸爸，他是个无聊的人。

后来我看见他在工作，

在建筑工地上。

他高高地在云端

比风筝还高。

他走在一块狭窄的木板上

不恐高，

不害怕，不像我一样害怕。

我的爸爸，他是个超人

My Views on Environmetal Protection

Nowadays, the world we live in is becoming more and more intolerable because of environmental destruction. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. Recently,haze weather has become a usual phenomenon here in large part of China. People are forced to wear the mask to avoid breathing poisonous air. Some people think it is impossible to solve the problem,however,from my opinion,if we find out the reason and take effective measures the environment can be better.

If we trace the cause for haze weather,the main points are as follows,first,our countrys air quality standards are rather lax and evaluation factors are limited,so you will see that current air appraisal system has defects. Second,some people just go for economic interests instead of turning out products according to relevant law and regulations. They tend to use obsolete equipment in which they are more likely to emit a great deal of wasted air. Third,across our society,the awareness of protecting the environment has not built up so that people havent formed a habit of using green product and saving energy as much as possible. If we dont take action to show respect to the environment, we will have to face an increasingly awful situation.

Therefore, effective measures should be taken and laws passed to conserve the environment. In my opinion, to protect the environment, the government must take even more concrete measures. First, people should be educated to recognize the importance of the problems, to use modern methods of birth control, to conserve our natural resources and recycle our products. Second, much more efforts should be made to put the policy of population into practice, because more people mean more pollution. Finally,laws concerning environmental protection should be put into effect and enforce strictly just as our government has been doing. To sum up,if we work together to take out such measures,our environment will get better and better and haze weather will vanish completely.

Hello, everyone. My name is Kelly. I am friendly and honest.I am good at English and maths. I like surfing the internet,playing computer games, watching TV and traveling. I also like playing table tennis and I am good at it ,too. I often play table tennis with my friends on weekends. And I want to be a famous table tennis player when I grow up. What I like most is to see the seagulls flying freely in the sky so I often go to the sea in summer. My favourite colour is white because I think white is symbolize purity.

大家好 我的名字叫KELLY .我很友好、诚实.我擅长英语和数学. 我爱上网、玩电脑网络游戏、看电视 和旅游.我也喜欢打乒乓球.我经常和朋友们在周末打乒乓球,长大了我想当一个乒乓球运动员.最喜欢在海边看着海鸥自由自在的飞翔,因此在夏天我经常去海边.白色是我的最爱.因为我觉得白色是纯洁的象征.

动物，本身就和我们人类是同等级的生物，我们只是不过拥有了智慧罢了。但是现在有许多人还在残忍地杀害野生动物。所以我呼吁大家保护动物，也正如有一句话所说的：“枪响之下，没有赢家;没有买卖，就没有杀害。”

保护动物，首先就是要减少、制约那些偷猎者等坏人。我们国家需要不断完善相关法律，加大执法和打击的力度，切实有效的打击罪犯。同时，我们也要减少购买用野生动物制作的工艺品、服饰等非必要的物品。也许你可能在想，一个小小的象牙工艺品，我花了很多钱，也没有关系。但是，只是一个象牙，那么就要杀掉一头成年象，也许在你看来没什么，但是对于象来说，它需要生存多久，躲避那些天敌，才能有这个象牙。所以，保护动物，也要从身边自身做起。

此外，保护了动物，我们就保护了生物多样性，让它继续长存，这也同时间接地保护了我们人类自身。在生物学里，生物多样性是一个很重要的部分，在生物圈里，也就是地球表面发挥着巨大无比地作用。物种越多，这个生物圈里，这个系统也就更加稳定，难以被破坏，或者说拥有了很强的自愈能力。所以，我们地球上的生物越多，我们生态环境也就更加稳定。但是没有了动物等生物，那么我们将会受到自然地惩罚，也终将走向灭亡。

动物，是我们的好朋友，也许你认为老虎狮子等很凶，但是他们也都是为了自保，也只有这样，他们才能更好地生存。此时我，我也相信你已经认识到保护动物的重要性了吧。所以，最后，让我们一起来保护动物吧，一起呼吁，让我们的生态维持稳定，保护动物，保护生态，就是保护我们人类自己。

Today, I went out with my best friend. When we arrived at the park, it

rained. We had to run in the rain because we couldnt find a place to hide. But

we still feel happy because we could comfort each other. The rain stopped later

and I accompanied her go home. We played in her home for a while and she invited

me for dinner. I refused because I feel it will bring trouble to his family. I

am happy today because the new term is coming. I really want to see my

classmates again

今天和最好的朋友一起出去玩。我们来到公园后，却下起了好大的雨。我们无处可躲。在雨中奔跑着。可是我们却很高兴。因为有彼此的安慰。过了一会，雨停了。我陪着她回家。然后在她家玩了一会，他留我在那里吃饭。可我拒绝了，因为有些不好意思。今天我很快乐，马上就开学了，真想快点见到同学们。

Panda is our country’s treasure, we should protect it. nowadays, we see from the TV that panda is less than before, it is not only because of the damage of the environment, but also the weakness of the panda. Everybody loves panda, it is so lovely, a panda has two black eyes, it is very lazy, it likes sleeping all the time. When we see its round body shape, we can’t help loving them. In order to see the lovely animal, we need to protect them. We must protect the environment, like not to throw the rubbish away, not to cut down the trees. We condemn such behavior that killing the animals. Protecting the animals is everybody’s job.

熊猫是我们国家的珍宝，我们应该保护它。现在，我们可以从电视上看到熊猫比以前少，这不仅因为环境的破坏，还因为熊猫自身的脆弱。大家都喜欢熊猫，它很可 爱，熊猫有两只黑色的眼睛，很懒，总是在睡觉。当我们看到熊猫圆圆的身形时，忍不住喜欢它们。为了看到这些可爱的动物，我们需要保护它们。我们必须保护环 境，比如不随处扔垃圾，不砍伐树木。我们谴责杀动物的行为。保护动物，人人有责。

Saving Water

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

节约用水

我们的世界不仅饥饿，而且因为缺水而干渴。对你来说这可能似乎奇怪：因为我们的地球表面75%由水覆盖着。但是，这巨大的数量中97%是海水、或咸水。只有剩下3%

的来自河流、湖泊、地下，和其他来源的淡水供人们饮用、使用。即使如此，这3%的水源我们也不能够完全使用，因为有些淡水是以冰山或冰河的形式存在。更糟糕的是，一些水源已遭受了污染。

然而，尽管按现状看来，这些少量的淡水即使时常转化成雨水的形式，对我们来说，也仍然够用。可是我们对水的需求却日益迅速增长。我们只有现在采取措施解决这一问

题才能避免未来世界范围内的严重水资源缺乏。限量供水会对农业和工业产生不良的影响。我们举个小小的事例就能证明水对工业的必要性。每生产一吨钢材就要消耗91，000升水，你知道吗?

我们必须杜绝对宝贵水资源的浪费。我们应该采取的第一步就是要发展水再利用的方法。该领域的实验已在进行，但是仅是小规模地进行。水资源再利用系统的重要性

对我们而言，与空间站不相上下。

This is the first diary I’m writing in the youth summer camp.

Everything is new to me, new class, new teachers and new classmates. My

classmates are all good students and they can speak English well. I think I can

learn a lot from them, and I can make friends with them.

The teacher from china is full of emotion when giving a class. And her

class is very interesting. To my surprise our foreign teacher can speak chinese

very well, but in my opinion, her class is a little boring. She should have made

the class more active.

Compared to my school, Zhejiang University seems so big that it takes us a

few minutes to commute between the classroom and cafeteria.

I wish myself good luck and have a good holiday here!

这是我在青年夏令营写的第一篇日记。

一切对我来说都是新鲜的，新的班级，新的老师和新的同学。我的同学都是好学生，他们英语讲得很好。我想我可以从他们身上学到很多，我可以和他们交朋友。

这位来自中国的老师讲课时感慨万千。她的课很有趣。令我惊讶的是，我们的外教汉语讲得很好，但在我看来，她的课有点无聊。她本该让全班更活跃。

与我的学校相比，浙江大学似乎太大了，我们从教室到食堂之间要花上几分钟的时间。

祝自己好运，在这里度过一个愉快的假期!

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 bee 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。

同学们，想像一下吧，如果全世界的动物都没有了，生机勃勃的的世界会怎么样呢?听不见小鸟的鸣叫，看不见小鱼在活泼的游来游去，闻不到臭鼬臭粠粠的身子，摸不到小兔温暖的毛，很多关于动物乐趣，将再也享受不到了，所以保护动物真的很重要。

动物虽然不会与人类交流，但要是人类在动物有困难的时候帮助他，他也会帮助你。特别是狗，你和它生活久了，它就会把你当成自己的家人。有一部电影叫《忠犬八公》讲的是一个真实的故事，有一只狗，叫小八，它的主人对它精心照顾，小八每天送主人到火车站，接主人回家。有一天，主人生病去世了，没回来，小八就一直等呀等，还是没等着。最后，它每天去火车站，风雨无阻，等了整整十年，直到死去。一条多么让人敬佩的狗哇!

动物对人类这么友好，人们呢?毫无感谢之语，反而会杀害小动物。比如：取熊胆，就是把熊的胆汁取出来，熊每天都非常痛苦，许多熊都自杀了。还有海豚湾里的海豚，日本人最喜欢吃海豚里的一块肉，所以把它们杀了，鲜血直流，染红了大海。还有拔象牙，把拔掉的象牙拿去贩卖，把老虎杀了，拿它的骨头做药等。我们也会伤害一些小动物，把色彩缤纷的蝴蝶抓起来，关在铅笔袋里;把匍匐前进的蚯蚓踩死;把翩翩起舞的飞蛾翅膀折断等等，不管动物小不小，丑不丑，我们都要保护它们。

同学们，勿以善小而不为，勿以恶小而为之。动物是我们人类的朋友，动物能带给人们幸福，带给人们友谊，带给人们欢乐。让我们行动起来吧!一起携手，保护动物。

“重庆市大巴山动物园的珍惜濒危动物╠五只大熊猫患上了离奇绝症需送国外抢救治疗，请同学们伸出援助之手，帮助那正要踏进死神殿堂的动物们吧！”第三节课间休息时，广播里传出动员大家出动的号召。

听到广播号召，同学们三三两两在教室议论起来，这时，只见班长杜鑫走上讲台，大声对我们说：“同学们，保护珍惜动物是我们共同的责任，大家都把平时的零用钱捐献出来，为抢救大熊猫做一点贡献吧！”大家听了，齐声拥护。班长到座位上拿出笔记本，就开始纪录同学们捐款了。同学们一齐围了上来，手里拽着一元、二元、五元的钞票，争先恐后地递给班长。班长的周围被围得水泄不通，不停地收钱，记载，一会大颗的汗珠开始从太阳穴顺流而下，汗珠最后降落在等记的课桌上。

下午第一节课的上课铃响了，老师来到课堂看到了同学捐款的场面，静静地观看着，脸上露出了欣慰的笑意。捐款登记完了，老师对我们说：“一会儿，学校将要举行捐款仪式，我们到操场上集合，请大家遵守秩序。”

全校同学们都来到操场上，主席台中间矗立着一个捐款箱，校长简单介绍后开始进行捐款仪式。校长，老师们依次走到捐款箱，投进了捐款，各班的班干部也带着全体同学的心愿走上捐款席，用一张写着多少钱，捐款慢慢地投了进去，同学们默默地注视着，脸上充满了自豪。

“一年级一班捐款125元……五年级六班捐款145元……总收到捐款4千多元，感谢同学们的爱心！”校长宣读完毕，操场上响起热烈的掌声。

这次活动，让我感到，我们要充满爱心，因为只有爱能创造奇迹！

I used to pouring away the water directly after I using it. Someday, my

mother asked me to help her wash the clothes, as I was about to pour away the

water, my mother stopped me and she told me that most water can be recycled. It

can be used to water the flower or to wash other things. From then on, I realize

how to save water.

我过去常常在用完水后直接倒掉水。有一天，妈妈叫我帮助她洗衣服，就在我要去倒掉水的时候，妈妈阻止了我，她告诉我说大部分水可以循环利用。那么水可以用来浇花或者洗别的东西。从那时候起，我就意识到如何节约用水。

Finally, we arrived in Guilin. After breakfast, we went to River Li. We

listened to the guide and enjoyed the views on boat. But I found the water in

River Li is dirty, many people washed clothes there. I feel angry and the trip

became boring and exhausting.

今天终于到了桂林，我们吃过早饭后就出发去漓江。坐上了船后，我们听着导游的讲解，观赏着风景。可是我发现漓江的水很脏，有很多人在那里洗衣服。我很气愤。在接下来的旅途中很无聊我也很疲惫。

This fish earned its name by utilizing evasion as a way to escape its predators. It bodily leaps from the ocean, reaching a speed of about 35 miles per hour and a recorded gliding time of up to thirty seconds. This can take them as far as 200 meters from their point of exit from the water, which may be far enough to escape pursuit or confuse predators. Fishermen favor these types of fish, but due to their sheer numbers in the wild, none of the 40 different species of flying fish are listed as endangered. While they can be found foraging seasonally along the outskirts of warm water reef complexes, flying fish are primarily pelagic, and favor tropical or subtropical open waters around the equator.

飞鱼得名于它独特的避难方式。遇到捕食者时，飞鱼会采用一种独特的逃跑方式：它会纵身一跃，跳出海面。此时它的速度可达到每小时35英里，在空中滑翔长达30秒。这一跃能使它们飞行200米，足以使它们全身而退或者迷惑捕食者。渔民们很是钟爱这种鱼，野生飞鱼数量众多，所以40种飞鱼中没有一种濒临灭绝。人们发现飞鱼有时会季节性的在温水区近郊地带的杂礁灰岩附近觅食，不过它们属浮游类鱼类，喜欢在赤道附近的热带，亚热带地区的公海活动。

Subsisting mainly on a diet of plankton and small marine life, flying fish are schooling fish that hunt primarily at night. While some sources may find this counter-intuitive, given the ease with which the fish are drawn to light sources, this actually makes perfect sense. Many of the plankton and marine resources the fish favor are slightly luminescent, especially by moonlight, making them easily seen in the darkness. This also provides cover, given the coloration of the fish—blue or grey on top, silvery white on the bottom—so that they are not easily seen from above or below as they feed on the clouds of marine flora. Flying fish generally mate during the autumn or spring, when currents are at their weakest. Females will deposit their eggs on the surface, attached to flotsam, and males will fertilize the eggs. Schools at this time can number in the millions, and constitute a major resource for species that feed on the fish. Because they only tend to live about five years in the wild, their flesh is prized for its purity—free of the heavy metals often found in longer-lived species.

飞鱼主要以浮游生物和小型海洋生物为食，主要在夜间以集群的方式进行捕食。有些人会觉得下面这个说法有悖常理，因为鱼类易被光源吸引，这么说也不无道理。许多浮游生物和鱼类自身都会发出微弱的冷光，尤其是在月光照射下，更是清晰可见。但这同时也为鱼类提供了一层防护，让它们有了保护色：一般在上部会呈现蓝色或灰色，下部呈现银白色。凭借这些保护色，当飞鱼在海底植物中进食时就很难发现它们。飞鱼通常会在春秋时节进行交配，因为这个时期洋流的活动最为和缓。雌性飞鱼会将卵产在海面上，让其依附在漂浮物上，雄性飞鱼再让鱼卵受精。此时在飞鱼的集群中，会有数以百万的成员。而这也为以鱼类为生的动物们提供了主要的食物来源。由于野生飞鱼只有5年的寿命，它们不会像长寿的鱼类一样体内留有大量重金属物质，因此飞鱼肉被人们视为珍品。

As everyone knows,English is very important today.It has been used

everywhere in the world.It has become the most common language on Internet and

for international trade. If we can speak English well,we will have more chance

to succeed.Because more and more people have taken notice of it,the number of

the people who go to learn English has increased at a high speed.

But for myself,I learn English not only because of its importance and its

usefulness,but also because of my love for it.When I learn English, I can feel a

different way of thinking which gives me more room to touch the world.When I

read English novels,I can feel the pleasure from the book which is different

from reading the translation.When I speak English, I can feel the confident from

my words.When I write English,I can see the beauty which is not the same as our

Chinese…

I love English,it gives me a colorful dream.I hope I can travel around the

world one day. With my good English, I can make friends with many people from

different contries.I can see many places of great intrests.I dream that I can go

to London,because it is the birth place of English.

I also want to use my good English to introduce our great places to the

English spoken people,I hope that they can love our country like us.

I know, Rome was not built in a day. I believe that after continuous hard

study, one day I can speak English very well.

If you want to be loved, you should learn to love and be lovable. So I

believe as I love English everyday , it will love me too.

I am sure that I will realize my dream one day!

Thank you!

亲爱的老师，同学们：

我很高兴可以在这个课堂上做一次演讲。这一次，我想谈谈英语。我的话题是我爱英语。

正如每个人所知，英语在今天十分重要。它已经被应用到世界的各个角落。它已经成为商业上最为通用的一门语言并广泛的用于国际贸易。如果我们能说好英语，我们就有更多的机会成功。因为越来越多的人注意到这一点，学英语的人数正在已很高的速度增长。

但是对我而言，我学英语不仅仅因为它的重要性以及它的实用性，更是因为我喜爱英语。当我学英语时，我可以体会到一种不同的思维方式，它可以给我更多接触世界的空间。当我读英语小说时，我能感受到不同于阅读翻译文的快乐。当我说英语时，我可以感到自信。当我写英语时，我能够感到不同于汉语的那种美……

我爱英语，它给了我一个色彩斑斓的梦。我希望有朝一日我可以畅游世界，用我流利的英语，我可以和世界各地的人交友。我能看到许多的名胜。我希望我能够到伦敦去，因为那里是英语的故乡。

我也希望用我流利的英语来将我们的名胜介绍给说英语的朋友，我希望他们可以像我们一样的爱我们的国家。

我知道，罗马不是一天筑成的。(成功需要日积月累。)我相信在持续不断的努力学习下，总有一天我可以拥有一口流利的英语。

如果你想被爱，你就应该学着去爱他人。所以我相信我对英语的爱定将换来它对我的爱。

我相信总有一天我会实现我的梦!

谢谢!

Animals are our good friends, we should protect them, because a lot of animals is beneficial to human.

For example, I like little bees. It is very industrious, arrive every day, honey for the people.

I like the little green frog. It hid in the fields every day, as long as pests, will be the frog to eat into the belly.

I like the swallow. Its a beautiful singing voice, as long as the spring comes, they fly back from the south.

I like worms. It ran winding in the ground, turned out to be digging in to help the earth mother.

I like small gecko. Its tail special magical, broken can come back for yourself. Also can help mankind to catch mosquitoes.

Little friends, do you like the animals? So lovely small animals, we mustnt hurt it.

动物是我们的好朋友，我们应该保护它们，因为很多动物对人类有益。

比如，我喜欢小蜜蜂。它很勤劳，每天早出晚归，为人们采蜜。

我喜欢小青蛙。它每天都躲在田地里，只要害虫一来，就会被青蛙吃到肚子里。

我喜欢小燕子。它的歌声很优美，只要春天一到，它们就从南方飞回来。

我喜欢蚯蚓。它在地底下弯弯曲曲的跑着，原来是在帮助大地妈妈松土。

我喜欢小壁虎。它的尾巴特别神奇，断了能自己再长出来。还能帮助人类捉蚊子。

小朋友们，你们喜欢这些小动物吗?这么可爱的小动物，我们千万不能伤害它。

I do not like teamwork in most time. Because I think it is hard for the

whole team to hold the same view. It is a waste of time to argue with each other

then make a compromise. But recently I have really seen the great power of

teamwork.

Last week we had a play competition. Because of some reasons, we had not

decided the play two days before the competition. Our monitor called the actors

and actresses who had been decided together. Then they think about every plot

together. To my surprise, it seemed that everybody had his or her good idea.

They gave up their weekend to practice the play. Finally our team won good marks

and were given the opportunity to participate in the final competition.

Teamwork is really powerful. No matter learning in school or working in the

future, we have to work in a team sometimes. So, try to establish the spirit of

teamwork. It will surely help you achieve success.

在大多数时间我不喜欢团队合作。因为我认为它是困难的为整个团队持有同样的观点。这是一个浪费时间争论然后互相妥协。但最近我真的见过伟大的团队合作的力量。

上周我们有一个玩的竞争。因为一些原因,我们没有决定竞争前的玩两天。我们的班长叫男女演员曾决定在一起。然后他们一起思考每一个情节。令我惊奇的是,似乎每个人都有他或她的好主意。他们放弃了周末练习。最后给出我们的团队赢得了好成绩,参加总决赛的机会。

团队合作真的很强大。无论在学校学习或工作在未来,有时我们必须在一个团队工作。所以,尝试建立团队合作的精神。它一定会帮助你取得成功。

A triple bacon cheeseburger seems like a heart attack on a plate.

三层奶酪咸肉汉堡感觉吃完很容易让人突发心脏病。

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。

Dear Kate,

亲爱的凯特,

This term I moved to a new house and studied in a new school. But I always

missed my friend. My old house was move comfortable than this new house. I

wanted to go back to my old house.

这学期我搬到新房子,在一所新学校学习。但我总是想念我的朋友。我的老房子是比这舒适的新房子。我想回到我的老房子。

Everything was strange for me,so I couldnt study better. I felt nervous in

the first test. And I got bad scores,I felt very sad. The teacher shouted at me.

And then,I felt under too much pressure and very tired. My parents were also sad

with me. When my classmates knew this thing,she helped me,and gave me some

advice. Later,I thought I can be better next time.

一切对我来说是陌生的,所以我不能更好的学习。在第一个测试中我感到紧张。我得到糟糕的成绩,我感到非常难过。老师对我大吼大叫。然后,我感到太多的压力和很累。我的父母和我也难过。当我的同学知道这件事,她帮助了我,给了我一些建议。之后,我想我可以更好的下一次。

I hope to get on well with everyone and get a good mark soon.

我希望和每个人都相处得很好,很快就取得好成绩。
