I like dogs, because they are man’s good friends. They can do many helpful things to us, such as guarding our houses, greeting guests, helping the police, and so on. Some trained dogs can even lead the blind people and save people’s lives. So they‘re treated as our family members. I hope someday dogs will be in great harmony with human-beings.
我非常喜欢狗,因为它是人类的好朋友。它可以为我们做很多有用的事情,如,保护房子,问候客人,帮助警方等等。一些受过训练的狗甚至可以引导盲人、拯救人们的性命。所以它都被当做是我们的家庭成员。我希望有一天狗能与人类和谐共处。
极地由于交通运输十分不便,因此积雪就成了当地最方便的建筑材料。世界最大的岛屿格陵兰岛北部的爱斯基摩人过着随时迁移的渔猎生活。为了适应这种生活习惯,他们靠山吃山,靠水吃水;就地取材,随心所欲地利用积雪作为建筑材料,建造起一座又一座令人赞叹的“爱斯基摩人小雪屋”。很多在北极寒风中冻得四肢发僵的探险家和旅行者,一踏进爱斯基摩人低矮的小雪屋,都曾用动人的笔调和喜悦的心情来追述小雪屋的温暖与舒适:有的说像沙漠里的游子遇到了清泉,有的说像漂流的海船遇到了大陆……的确,那沁骨的寒冷已留在屋外。雪屋中央的北极白熊皮上,坐着雪屋主人的一家,旁边燃烧着一堆熊熊篝火,茶壶咝咝地喷出白色的蒸汽……在雪堆里烤火有没有危险?不必担心,雪屋刚开始点篝火的时候,屋里的墙壁和天花板会融化一些,但融化的只是一小薄层而已。当墙壁和天花板上融化的薄层慢慢冻结成一层冰壳以后。篝火再也不会融化冰壳和冰壳外面的雪屋了。根据不少北极探险家的报道,这种小雪屋里的暖和程度,即使屋外气温达到-50℃,雪屋里的人也可以不穿毛衣。
今天爸爸给我买了一只可爱的小鸡,全身长着桔黄色的茸毛,我给它起名叫“小黄”。小黄两只小眼睛一眨一眨的,像小星星一样,它的爪子还没有长得那么坚硬有力,让小黄显得更加可爱。小黄最喜欢做的事情就是趴在我的脚上睡觉。毛茸茸的、软软的身体,让我感觉到脚暖和极了。
Today, my father bought me a lovely chicken, covered with orange hair, I called it \"yellow\". Miss Huang\'s two small eyes blink and act like a little star. Its claws are not so strong and strong as to make Xiao Huang look more lovely. Xiao Huang\'s favorite thing to do is to sleep on my feet. The fluffy, soft body made my feet warm.
看着它睡得香甜,我不忍心动一下,生怕惊醒它,当我挪动我的脚时,它还恋恋不舍地追随我的脚。到了晚上小黄还是唧唧的叫着,要我陪它。于是我做了一个脚的模型,周围放了温水瓶,这样小黄就安心入梦了,看着它睡着了,我也安心地睡觉了。
It looked at sleep soundly, I could not bear to heart, afraid of waking it, when I move my feet, it is unable to part my feet to follow. In the evening, Xiao Huang still chirped and asked me to accompany him. So I made a foot model, surrounded by warm water bottle, so his yellow dream, watching it fall asleep, I also sleep at ease.
小黄还喜欢跑来跑去和我捉迷藏,有一次,我找了半天,也没找到它,后来,在我的.澡盆里发现了小黄。它在里面怎么飞,也飞不出它自己不小心蹦进去的澡盆了。看着它,我笑了,小心翼翼地把它拿出来了。我的小鸡“小黄”可爱吧!
Huang also love to run and hide and seek, once, I am looking for a long time, did not find it later, Huang was found in my bathtub. It can fly inside, also can not fly out of its own in the bathtub was accidentally jumped. Looking at it, I smiled and took it out carefully. My chicken \"Yellow Daisy\" is cute!

Elephant has been and is a vital tool for people to do many things that would normally be imposs-ible.
Elephant is and will continue to be one of the greatest creatures man has ever come into contact with. Its size. beauty, and power willforever be useful to man.
对于地球这样一个球体来说,哪里算是尽头呢?南极的前后左右都是朝北的地方,推而论之,北极前后左右都朝南。当然,这仅仅指的是地理极点而已,也就是地球自转轴与固体地球表面的交点。当你站在北极点上,只需原地转一圈,便可自豪地宣称“已经环球一周了”。
I have a big dog ane I love him very much .he has two round black eyes and his sense of hearing is sensitive .
His claws are like four plum blossoms .His tail always shakes and looks very cute .In the daytime ,he likes sleepping under the sunshine .
But at night ,he is careful and keeps like the doorkeeper guards .He is smart and always eat a lot .He is meek to me but when he meets strangers ,he will bark to them .
When I become tired ,he will come and lick my face with his tongue .when I am not busy ,he will play with me .He can give me so much happiness and now I can not leave him .I love my dog because he is one of my family numbers .
生活在北冰洋里的哺乳动物有与众不同的保暖方陪。例如,一只海獭的身上竟生有8亿根毛,而一只海狗的身上每平方厘米则有46 000根毛。它们身上的毛如此之密,以至于连无孔不入的海水也无法渗透进去。在这些浓密的毛发之中充满着干燥而温暖的空气,使它们即使在冰冷的海水之中,也能生活得非常舒服。
海豹、海象和鲸等大型海洋哺乳动物有一个共同的特点,即它们的体型都呈圆形,像个炮弹似的,这不仅使它们在游动时大大地减少阻力,而且也有效地减少了热量的散失。当然,它们之所以能在冰冷的海水中保持住自己40℃左右的体温,主要还是得益于极厚的皮层和皮下那层厚厚的脂肪。不同种类的鲸,其皮下脂肪的厚度是不一样的,有的只有几厘米,有的厚达半米,起到了很好的隔热作用。然而,有其利则必有其弊,当鲸鱼长时间的游动或者遇到危险拼命逃跑时,其身体内产生的大量热量就很难散发出去。为了解决这一问题,在其皮层表面以下分布着一个密密麻麻的血管网络,由神经和肌肉加以控制。当其过热时,大量热血就会流进这个网络中加以冷却,使体温降到3℃左右,其作用就像汽车的散热片差不多。
在北极,连小小的旅鼠也有其绝招。在严寒的冬季,它们是靠地道战求生存的。但是,要在冻土打出四通八达的地道网并非一件容易的事,因此每到秋天,旅鼠的前爪就会长出一个厚厚的角质层,就像是两把小铲子似的,打起洞来就要快得多了。
狐狸、狼、麝牛和北极熊等大型动物主要是靠丰厚的绒毛和不停地运动来保持体温并抵御寒冷的。北极熊虽然有时候也会冬眠,但却不是抱头大睡,而是睁一只眼,闭一只眼,保持着高度警惕,只要稍有风吹草动,它们会立刻觉醒,随时准备出击。
My favorite animals are swans.they are white.they can swim very well.I think they look like a beautiful girl in a white dress.they have a pair of wings and they can also fly well.I believe they are angles from the sky.they bring us love and make us happy.they are always friendly to us.We can\'t hurt them,because they are our friend.I love them!I like dogs,too.they are not beautiful,but they are the best friends.they keep the thieves away.Dogs have the best listening and eyes.they can hear in the nosiy,see in the dark.If we are in danger,they will help us at once.And they don\'t mind their lives.So,I love them.
