My Pet

I have a pet. I named him Nicholas. Nicholas is a pure Husky dog. He was about 8 weeks when he first came to my home. We will have his birthday next week and he is turning 2 years old. Good time goes fast. Hes totally mature now but somehow I just refuse to admit it. In my eyes, no matter how big the size he is, hes just my adorable puppy. Owning a dog is a huge responsibility. I spent a lot of time house-trainning him. Youd have to be patient, compassionate, and consistent. Fortunately, Nicholas is a fast learner. Now he knows exactly where to go potty, what time to eat, and how to play. He used to be too energetic and he liked biting. But now, as hes growing up, hes gentle and obedient. On week days, I take him to parks. I toss out his toy and he goes and get it. He loves this game. Nicholas brings me lots of fun and Im proud of being his owner.

Recently I have seen such a story, the story on the way to save a giant snake women in banda aceh in Indonesias aceh province provincial capital, a woman under the guidance of a serpent, arrived in safety. 26-year-old woman riza said, on December 26, 2004, she lives in a village was flooded with waves, panic in the people running for their lives.

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. After the event, riza said: "very strange when meet the serpent, I do not feel panic." Moreover, the serpent did not bite them.

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。

Russian Scientists Surrounded by Polar Bears

俄罗斯科学家被北极熊包围

Relief supplies finally arrived on a remote Arctic island where a group of scientists had been trapped in a weather station. Up to a dozen polar bears had surrounded the station on the island of Troynoy and set up camp approximately two weeks ago. The bears were becoming more aggressive over time, killing one of the stations dogs and breaking a window. On Wednesday, a helicopter that picked up supplies from a nearby vessel arrived with dogs and flares and was able to scare away the bears and allow the researchers to get back to work.

救灾物资终于抵达了偏远的北极岛屿，有一批科学家被困在那里的气象站中。大约两周以前，十几只北极熊将特洛伊诺伊岛(Troynoy Island)上的一个气象站团团包围，并在那里安营扎寨。随着时间的流逝，北极熊变得越来越有攻击性，咬死了气象站的狗，还打破了窗户。周三，一架从附近船只上携带犬和照明弹物资的直升机到达岛屿，能够将北极熊吓走，让科学家正常工作。

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 Need Protecting

Earths biological diversity is being fast decline of many species facing extinction. Threat to the survival of wild animals and plants is a major factor in habitat loss, business development, and wild animals and plants and their products in international trade. Resources are limited, it is necessary for the endangered species, to propose specific measures of protection level. We can formulate the corresponding endangered species laws, application to establish nature reserves, endangered species breeding centers, means of conservation biology, endangered species, the implementation of in situ conservation and ex situ conservation. At the same time, we must restrict international trade in Endangered Species of Wild Fauna and Flora, to make laws to protect endangered species.

In our country,the number of wild animals is becoming smaller and smaller.Some of them are even dying outThe dangerous methods we human being has taken are as follows:

We have been cutting the trees to build houses,so the home of animals is intruded and they have to find new places to live.In this process,some of them died in the new environment.

The abuse of pesticide has also been endangering the life of wild animals.

In addition,in order to earn money,people have been killing the rare wild animals.

In that we have realized the threat of our behavior to our best friends,we should take actions to change such a condition by taking the following methods:

We should protect the wild animal by protecting the environment that they live in and protect themselves,not to hurt them.At the same time,we should establish more natural reserves for the wild animals.

I believe as long as work together to protect the wild animals,our life will be more and more comfortable.

在我国,野生动物的数量正变得越来越小。他们中的一些人甚至死那个危险的方法我们人类采取了如下:

我们已经减少树木盖房子,所以家里的动物侵入,他们不得不寻找新的居住地。在这个过程中,他们中的一些死于新环境。

农药的滥用也危害野生动物的生命。

此外,为了赚钱,人被杀死珍稀野生动物。

在我们意识到我们的行为的威胁我们的最好的朋友,我们应该采取措施改变这种情况采取以下方法:

我们应该保护野生动物,保护环境,他们住在保护自己,不要伤害他们。与此同时,我们应该建立更多的自然保护区的野生动物。

我相信只要共同努力,保护野生动物,我们的生活将会越来越舒适。

那天，我妈妈给我买了两只小鸭子。我很高兴，把两只小鸭子放在箱子里，听着它们的叫声，我的心情非常的好。

We put a duck on the ground, it went forward a few steps and then fell, it caught up, and fell down, and we laughed. We play enough, put the duck into the box, to play with toys.

下午，我和爸爸去看小鸭子，看见一只鸭子肚子朝上，翅膀和脚在抖动，它叫的声音很大，好像在哭一样。爸爸把小鸭子扶起来，小鸭子又倒了。我突然想起来我把小鸭子扔进箱子里的事，呀!我是杀人凶手呀!我哭了。小鸭子最后死了，我很伤心。

Afternoon, my father and I went to see the little duck, see a duck belly up, wings and feet in jitter, it sounds great, like crying. Dad put up little duck, duck down. I suddenly remembered that I took the little duck into the box,! I am a murderer! I cried. Little duck finally died, I am very sad.

从那时起，我就开始爱护小动物了。

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。

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.

Nowadays, the biggest nature park for panda in China is in Sichuan. There is a research centre for nature and wild life there. Scientists hope that one day they will have enough pandas to be set free and let them live in the wild again.

I love dogs, dogs are the cutest animal ever on earth. From small and cute ones to big and fierce ones. I love all kind of them. They say dogs are mans best friends. I agree with that because dogs are royal, friendly and fun to play with. Some of them are extremely cuddly and soft to hold and hug. While some of them are extremely royal and helps us guard all our properties.

My favourite animal is dog.They are very cute.There are many kinds of dogs.Some of them are big and some of them are small,some of them are white and some of them are black.I like the big dogs,like a bulldog,because they can protect me.I dont have anydog yet,because my mum does not like dogs.she think they are dangrous.I Will buy a dog after I become older.

The dog is one of the most popular pets in the world. It ordinarily remains loyal to a considerate master, and because of this the dog has been called mans best friend. Class distinctions between people have no part in a dogs life. It can be a faithful companion to either rich or poor.

Dogs have been domesticated for most of human history and have thus endeared themselves to many over the years. Stories have been told about brave dogs that served admirably in war or that risked their lives to save persons in danger. When Pompeii--the Roman community destroyed by Mount Vesuvius in AD 79--was finally excavated, searchers found evidence of a dog lying across a child, apparently trying to protect the youngster. Perhaps few of the millions of dogs in the world may be so heroic, but they are still a source of genuine delight to their owners.

A dog fits easily into family life. It thrives on praise and affection. When a master tells a dog that it is good, the animal happily wags its tail. But when a master scolds a dog, it skulks away with a sheepish look and with its tail tucked between its legs.

People in the city as well as those in other areas can enjoy a dog. Medium-size or small dogs are best suited for the confines of the city. Large dogs need considerable exercise over a large area.

Dogs are not always well thought of, however. In recent years dogs in the city have been in the center of controversy. Some people have criticized dog owners for allowing their pets to soil sidewalks and lawns, although in some cities laws oblige owners to walk their dogs along street curbs. In turn, dog owners have argued that the animals serve as protection against vandals and burglars and thus protect their detractors as well as their owners.

When a person decides to own a dog, he should be prepared to care for it properly. For a dog to stay healthy it must be correctly fed and adequately groomed, and its medical needs must be met. For a dog to be well-mannered it must be properly trained. It should never be ill-treated or mishandled. Otherwise, it will bite in its own defense.

The wild ancestors of all dogs were hunters. Wolves and other wild relatives of the dog still hunt in packs for their food. Dogs have retained the urge to be with the pack. This is why they do not like to be left alone for long. Some breeds of dogs still retain the hunting instinct.

Dogs exist in a wide range of sizes, colors, and temperaments. Some, such as the Doberman pinscher and the German shepherd, serve as alert and aggressive watchdogs. Others, such as the beagle and the cocker spaniel, are playful family pets, even though they were bred for hunting. Still others, such as the collie and the Welsh corgi, can herd farm or range animals. Each of the dogs just mentioned is a purebred. A mongrel dog, however--one with many breeds in its background--can just as easily fit into family life.

Dogs have been with humans since prehistoric times. Over the years they have performed various services. They have pulled sleds over snowy tracts. They have delivered messages, herded sheep and cattle, and even rescued persons trapped in the snow. Dogs have served as a source of food, too. The ancient Romans are said to have prized certain kinds of dog stew. The Aztecs of ancient Mexico raised tiny dogs, thought to be the forebears of the chihuahua, to feed the large carnivores in the private zoos of the Aztec rulers. In the past dogs have even been worshiped as gods. Recently, they have been used in drug research, medical experimentation, and space science. Soviet scientists launched dogs into space to test the ability of mammals to survive the rigors of space travel before people were sent up.

Dogs are trained as guard dogs in peacetime by the United States Army and other military services. Because of their keen sense of smell, dogs are used by police at times to track down escaped prisoners. Law enforcement agencies also rely on the dogs acute sense of smell to uncover illegal drugs. And specially trained dogs serve as the "eyes" of the blind, guiding the steps of their sightless masters around obstacles and hazards.

狗是世界上最受欢迎的宠物之一。它通常仍然忠于一个体贴的主人,因为这个狗被称为人类最好的朋友。人们之间的阶级差别没有生活在狗的一部分。它可以是一个忠实的伴侣,无论是富人还是穷人。

狗驯化在人类历史的大多数时期,因此球员很多。故事被告知关于勇敢的狗,令人钦佩的战争或冒着生命危险拯救的人处于危险之中。当庞培——罗马社区在公元79年被维苏威火山——终于被挖掘,搜索者发现一只狗躺在一个孩子的证据,显然试图保护这个年轻人。也许一些世界上数以百万计的狗可能是英雄,但他们仍然是一个真正的喜悦主人的来源。

一只狗容易符合家庭生活。在赞美和感情。当大师告诉一只狗,它是好的,动物快乐地摇尾巴。但当主人骂狗,它潜伏了一个羞怯的外观和它的两腿之间夹着尾巴。

城市的人们以及那些在其他领域可以享受一只狗。中型或小型狗是最适合城市的范围。大型犬在大面积需要相当大的锻炼。

然而,狗并不总是值得思考的。近年来狗在城市里一直在争论的中心。有些人批评狗主人允许宠物土壤人行道和草坪,尽管在一些城市的法律迫使业主限制他们的狗沿着街道散步。反过来,狗主人认为,动物作为防范破坏者和窃贼,从而保护他们的批评者以及它们的主人。

当一个人决定自己的一条狗,他应该准备妥善照顾它。狗保持健康必须正确美联储和充分培养及其医疗需求必须得到满足。狗必须得到适当的训练表现得彬彬有礼。它不应该虐待或处理不当。否则,它会咬自己的防御。

所有的狗都是猎人的野生祖先。狼和其他的野生亲缘狗仍然集体觅食的食物。狗有保留的冲动与包。这就是为什么他们不喜欢独处太久。一些品种的狗仍然保留了狩猎的本能。

狗存在大范围的大小,颜色,和性情。一些,比如杜宾犬,德国牧羊犬,作为预警和积极的监督者。其他的,如小猎犬和可卡犬,好玩的家庭宠物,尽管他们的狩猎。还有一些,比如牧羊犬和威尔士科基犬,可以群农场或范围的动物。每个狗刚才提到的一个纯种。一条杂种狗,然而——有许多品种的背景——可以很容易适应家庭生活。

狗自史前时代以来一直与人类。这些年来,他们已经在执行各种服务。他们已经把雪橇在雪大片。他们传递的消息,赶羊和牛,甚至救出被困在雪地里的人。狗也有担任过的食物来源。古罗马人据说炖珍贵的某些种类的狗。古代墨西哥的阿兹特克提出了很小的狗,认为是吉娃娃的祖先,给阿兹特克的私人动物园大型食肉动物的统治者。在过去的狗甚至被崇拜为神。最近,他们被用于药物研究、医疗实验,和空间科学。苏联科学家发射了狗测试能力的哺乳动物生存的艰辛太空旅行之前人打发了。

狗是训练有素的警犬在和平时期的美国军队和其他军事服务。因为他们的敏锐的嗅觉,狗被警察有时用来追踪逃跑的囚犯。执法机构也依靠狗的敏锐的嗅觉发现非法毒品。和受过专门训练的狗充当盲人的“眼睛”,指导的步骤失明的主人在障碍和危害。
