动物尾巴的样子各不相同,它们也有很多不一样的用处。
大象的尾巴像根绳子一样又细又长,尾巴终端长有坚硬的、稀疏的长毛。可别小瞧这细长的尾巴,它可以随性地延长尾巴的“势力范围”,它的尾巴左右一摇晃,就有效地驱赶了前来***扰的蝇虻。
老虎的尾巴毛茸茸的,又粗又长,健壮有力。那粗壮的尾巴有一个尤为重要的功能——维持身体的平衡!凭借这粗壮的大伙伙老虎就可以在丛林中自由奔跑。它的尾巴长约0。6—0。9米,和大象一样,也可以用来赶走苍蝇、豺等讨厌的小动物。
袋鼠的尾巴不只粗长,而且长满肌肉。当袋鼠慢慢行走时,它的尾巴能起到“5、肢”有哪些用途;跳跃时,尾巴则向后伸直,用来平衡身体;遇见危险时,那尾巴就变成了自卫和进攻的“武器”,一旦敌手被它那强有力的尾巴击中,就会有致命的危险。
尾巴是猴子的“5、只手”。猴子借助尾巴在树上蹿来蹿去,有时还用尾巴攫取食物。比如白颊猴就可以借助尾巴帮站立,蜘蛛猴可以用尾巴摘取果实。
松鼠的尾巴又大又蓬松,它可以加强松鼠的跳跃距离,遇见凶猛动物时,可以帮自己飞速逃脱。松鼠从树上往下跳时,尾巴张开,像降落伞一样维持着身体的平衡,如此一来松鼠就可以平平安安地落到地面上。让大家没想到的是这条又厚又软的大尾巴还是松鼠过冬的利器,盖在身上那真是太暖和了!
鹿的尾巴又短又小,但它却是要紧的警报器。当天敌挨近鹿群时,第一发现危险的那只鹿就会竖起我们的尾巴,向同伴发出警报。
动物的尾巴真是神奇而有趣,等待大家进一步的探索和发现。
I have a cat .Its name is Mimi. It\'s very lovey.My family all like it.

It\'s very good!so My family all like it!
On Sunday morning, my parents took me to the zoo. We did not go there for a long time. Last week, my classmates told me that the zoo added some funny entertainment facilities. I was very curious. So, I asked my parents to took me there and they promised to. We got there at 9 o\'clock. There were many people.
Most of them were parents and children. We first went to see the animal. I like parrots most. And then we saw the animal shows. Elephants, tigers, lions and monkeys did wonderful shows for us. People were happy, especially the children. After that, we went to experienced the entertainment facilities.
My mum was too scared to be with us. So, only my dad and I played. It was so exciting, but I was a little dizzy. However, I was very happy. It was a great day.
我是一只小蜜蜂。我们蜜蜂是过群体生活的。在一个蜂群中有三种蜂:一只蜂王,少数雄蜂和几千到几万只工蜂。我就是这千万工蜂之一。
我的母亲就是蜂王,它的身体,几乎丧失了飞行能力。这没有关系,它有千千万万个儿女,我们可以供养它,也算尽了孝道吧!在我的家族中,只有蜂王可以产卵,它一昼夜能为我们生下1?5万到2万个兄弟。蜂王的寿命大约是三年到五年,在我们家族中它可以说是寿星了。
在蜂群中还有一种蜂叫雄蜂,它和我们大不相同,它“人高马大”身体粗壮,翅也长。它的责任就是和蜂王交尾。交尾之后,它也就一命呜呼了。?要说家族中数量最多,职责的还是我们工蜂。我们是蜂群的主要成员,工作也最繁重:采集花粉、花蜜,酿制我们的“口粮”、哺育我们的弟弟们、饲喂我们的母亲、修造我们的房子、保护家园、调节室内温度和湿度……别看这样,我们的身体是非常弱小的,我们的寿命也只有六个月,就像天空的流星一样――一闪即逝,仅有一点儿时间去闪耀自己的.光辉。
我们蜜蜂是自然界里最勤劳的了。开花时节,我们忙得忘记早晚,有时还趁着月色采花酿蜜。蜜是很难酿的,我们要酿一公斤蜜,必须在100万朵花上采集原料。如果我们的蜂巢同采蜜的花丛距离一公里半,那么我们采一公斤蜜就得飞上45万公里,差不多等于绕地球赤道飞行11圈。看样子,我们的功业并不次于“阿波罗号”呢!虽然我们采蜜难,但每年一窝蜂都能割几十斤蜜。在广东的同族们一年四季都不闲着。如果动物世界也有组织的话,那么我们蜜蜂一定能获得“最热爱劳动奖章”。
也许您要问:在漫无边际的大自然中,你们怎么知道什么植物在哪里开花流蜜呢?告诉您吧,我们有很多“侦探”,派它们去侦察,回来再把结果告诉同伴,我们的“语言”就是舞蹈。
我们的家族就是这样。我们的生命是短暂的,但不必担心,我们还有兄弟,还有接班人。它们会像我们一样继续劳动。我们的家族就这样不断繁衍下去。
人们一提到虎,就会想到它那健壮的身体,锋利的爪牙和威风的样子。的确,虎被称为百兽,它是胜利和力量的象征。
在现实生活中,虎的数量很少。在九种虎中,有四种已经灭绝了。仅剩下的五种虎中,也有几种的数量仅剩两位数了。但美洲虎,东北虎的踪迹,还是可以在森林中找到,还是一样的威风。
东北虎的毛色非常美丽,额前有一个“王”字形的斑纹,一身淡黄色的长毛上夹杂着黑色条纹,显得十分漂亮;它那强健、粗壮的四肢和一对炯炯有神的眼睛,又使它显得威风凛凛。东北虎是肉食性动物,它身上最厉害的武器就是锋利的爪和犬齿。它的爪长达十多厘米,伸缩自如,比钢刀还利,就是牛皮也禁不住它一抓;犬齿长6厘米,是撕碎猎物不可缺少的“餐刀”;虎的舌头上有很多尖锐的刺,适于嘶咬。趾垫和掌心的肉垫,像海绵似的柔软,使东北虎走起路来像猫一样,无声无息,敏捷而富有弹性。
所有种类的老虎几乎都有这些特点,这是它们身体条件上的优势,而它们的捕食本领也比狮子高明,常采取静伏、潜行,好搞突然袭击。它的一声长啸,会吓得许多动物伏地不动,然后使用扑、掀和剪等方法来捕捉。虎的一扑很厉害,能远扑七米之外,跃高2米,一掌可以击倒一只鹿。它的尾巴就像一条铁棍,“一剪”可以打断动物的腰和腿。它还有尖牙利爪,遇上牛这样的大家伙,就从后面跃上牛背,抓住头颈,前顶后扯;如果从正面袭击,就会抓住咽喉,连咬带撕,再壮的牛也只能任它宰割了。
虎在热带和寒温带森林中都有栖息,它耐寒超过耐热,喜欢洗澡,常常出没在离水较近的草丛之间。在饱餐之后,它们一般都比较喜欢在安静的地方休息。虎与狮不同,一般都在晨昏时才出来觅食,但是行动却十分隐蔽。
除母虎带仔外,绝大多数的虎都是单独栖居,并有明显的巢域。母虎一般两三年一胎,一胎一般二仔。由于森林日趋减少,素有“森林的保护者”美誉的老虎不但保护不了被人类不断吞噬的森林,连自身的生存也受到环境问题的严重严胁。目前,我国虎类总共只有3000多只。
由于虎的价值大,数量又少,这“森林”的雄姿已很难见到。目前东北虎和华南虎均已被列为我们国家的一类保护动物,相信经过社会各界人士不懈的努力,一定会使子孙后代们永远可以见到这百兽――虎的雄姿。
