“第一场比赛——赛跑,总长1000豹步(豹子奔跑一步的距离),动物族派出了速度之王——猎豹,植物族派出了一棵小草,那小草对猎豹,看来动物族要赢了。”钢笔解说员正在给大家解说一些比赛的情况。比赛开始了,只见猎豹飞奔出去,转眼间就跑出了100豹步,真不愧是速度之王啊!突然,铅笔也出现在了解说台上,说道:“咦?怎么回事?小草竟然随风飘起来了,而且飞的明显比猎豹跑得快。10步、5步,快看!小草超过猎豹啦!”这时看台上梅花、樱桃带头鼓掌给小草加油助威。最终小草领先猎豹2豹步,小草赢了,植物族率先夺得了头筹。
“第二场比赛——举重,动物族竟然派出了蚂蚁,真是奇怪呀,植物族派出了一粒小种子。”比赛开始了,很多橡皮工作人员把种子放在一的大金属箱子里,又给它浇了水,接着他们又抬上一个一模一样的金属箱子,让蚂蚁抬起来,只见蚂蚁一用力,箱子就被举起来了,真是厉害呀!那边的种子还在顶金属箱子,可是最终还是没有顶起来。蚂蚁赢了,动物族搬回了一局!
“第三场比赛——飞行,动物组怎么没有派出飞行灵敏的蜻蜓,而是派出了蜘蛛,植物族派出了蒲公英。”一阵风吹过,蒲公英腾空而起,飞向终点,也就在蒲公英起飞之际,蜘蛛喷出一堆细丝,这一堆细丝就像是一张网,把蒲公英给粘住了,蒲公英飞不动了,接着蜘蛛又喷出一堆细丝,这一堆细丝就像是一个气球,把蜘蛛带到了终点,这一场又是动物族赢了,原来动物族派出蜘蛛是有目的的。
“第四场比赛——钻地,动物族派出了钻地大王——地鼠,植物族派出了仙人掌,这一次的重点很好玩,他被设在海平面以下300豹步处。”比赛开始仙人掌开始拼命的向下扎根,而地鼠则是一跳,头朝地面,一碰地,就开始向下钻,过了一会,从地下发出一阵欢呼声,和一阵叹气声,因为,仙人掌先到达终点,铅笔问仙人掌:“你是怎么赢的?”仙人掌说:“我在扎根的时候,先用一部分根把地鼠缠住,让他动弹不得,我在轻松自如的向下扎根,之后我就赢了。”所以,植物族搬回了一局!
“第五场比赛——爬树,动物族和植物族的决胜局,动物族派出了爬树高手——猴子,而植物族派出的是爬山虎。”比赛开始了,猴子拼命向上爬,一转眼功夫,它就已经爬到一半了,不愧是爬树高手,爬山虎也不甘示弱,也拼了老命向上爬,不一会也爬到了一半,可是猴子毕竟是灵活,一次性绕过所有障碍,而爬山虎是一次次爬过障碍,当然速度会慢一些,这一次,还是动物族胜利了!
最后,动物族已三局比二局战胜了植物族,获得第一。动物族派出了兽王——狮子,植物族派出了花王——牡丹,作为领奖代表,登上了领奖台。由群山之首——泰山和万河之源——长江为他们颁了金奖和银奖。这场比赛圆满结束。

全文共 576 字
+ 加入清单“尖嘴巴,花毛衣,爱吃小虫和小米。”你们猜,这是什么动物?哈哈,这就是我家既调皮又可爱的的小鸡。
我家里有只鸡叫黄黄。它全身黄黄的,好像披着一件毛茸茸的皮袄,每天都穿着,从来也不脱下来洗一洗。它的个子很矮,大家都笑它为“矮冬瓜”。它长得机灵可爱。你瞧,乌黑乌黑的眼睛,像两颗小小的黑豆。圆圆的鼻孔活像两个小句号,尖尖的嘴巴像一个钓鱼钩。起先,我认为黄黄没有耳朵,请教了老师才知道,小鸡的两只小耳朵镶嵌在脑袋的两边,被绒毛遮住了,很难被人发现。最有趣的是它的尾巴了,随着它渐渐长大,尾巴看起来就像一把扇子,有趣极了。
黄黄胆子很小。每当有人来到我们家院子时,它就急匆匆的跑到小花园里藏起来,等人走了才慢吞吞的走出来,在院子里悠闲地踱步找食物吃。它还喜欢躲猫猫,每当我和小鸡“玩”这个游戏的时候,它就藏在小花园里的神秘地方,让我怎么找也找不到,当我垂头丧气的回家后,它才神不知鬼不觉的从某个角落里偷偷走出来。我觉得我们家的小花园仿佛成了它的避难所,也好像是它的游乐园。
一次,我放学回家,走在小花园时看到黄黄跑到我的脚旁边,可怜巴巴的望着我,好像在说:“小主人,快点给我点水和米吧,我快饿的前胸贴后背啦。”我说:“黄黄,我马上来。”说着,我“嗖”的一声跑回家,拿一些米和一小碗水放到它的面前,它也毫不客气张开嘴巴“吧嗒吧嗒”的吃了起来。
这就是我的动物朋友——黄黄
篇17:写濒临危机动物的英语作文北极熊
全文共 3755 字
+ 加入清单When the Arctic Ocean freezes over in the autumn, polar bears set off in search of their favorite meals: fatty ringed seals and bearded seals. By the summer, the sea ice begins to melt and break apart. Deprived of access to the tasty seals, polar bears spend the summer fasting. At least, thats whats supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So whats a hungry bear to do?
Scientists once thought that polar bears might survive by supplementing their pinniped diet by turning to terrestrial foods like snow geese, their eggs and caribou.
"Weve had this debate in the literature about whether terrestrial foods are nutritionally relevant to polar bears during the on-land season when the ice has melted."
University of Alberta biologist Nick Pilfold.
"And weve known for a long time, going back to research in the early 70s, even going to back to early explorer logs, that polar bears will consume terrestrial based foods. But the debate was always whether those foods actually add up, energetically." In other words, do these substitutes provide enough nutrition to make up for the lost seals?
To find out, Pilfold and his colleagues estimated the weight lost each day by polar bears in the wilds of western Hudson Bay during the ice-free season, when they could ostensibly be chowing down on terrestrial foods. Then they compared that to the weight lost by bears that are temporarily held in Manitobas Polar Bear Alert Program.
While captive, the bears do not eat. They drop about one kilogram each day. But the wild bears, who had access to the Arctic snack bar, lost the same amount of weight each day. The results are in the journal Physiological and Biochemical Zoology.
"Which is really saying that the terrestrial foods do not have dense enough energy to offset the mass loss. So this idea that bears can just switch from eating sea ice–based food to land food and thats going to help supplement against longer ice-free seasons, that really doesnt show up in the data."
The problem is that polar bears evolved to rely on the marine diet.
"The food on land is protein and carbohydrate based, and the food the polar bears really focus on is fat. Fat is the name of the game for these bears; theyre highly adapted to absorbing that fat into their system and putting it onto their body as body mass, so they can fast on it later on. And the only thing thats going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when theres sea ice."
Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, cant last as long without sea ice. So as the Arctic warms, younger polar bears will disproportionately die out. Leaving the species survival in doubt.
北冰洋在秋季结冰以后,北极熊就会出发去寻求它们最喜欢的食物:富含脂肪的海豹和胡子海豹。海冰在夏季开始融化断裂。这使北极熊在夏季无法吃到美味的海豹,所以它们进入禁食期。至少,情况应该是这样。但是由于地球变暖,温暖的无冰季节越来越长。那饥饿的北极熊要怎么办?
科学家曾经认为,北极熊可能会转向陆地上的食物来补充它们对鳍足类动物饮食的需求,进而生存下去,这些陆地食物包括雪雁、雪雁蛋和北美驯鹿。
“文献中有过这类辩论,即在寒冷融化时陆地食物是否能满足北极熊的营养需求。”
尼克·皮尔福德是加拿大阿尔伯塔大学的生物学家。
“通过上世纪70年代初的研究,还有早期的探险者日志,我们很早以前就知道,北极熊会以陆地食物为食。但是辩论的焦点在于,这些食物是否能增加北极熊的能量。”换句话说,这些替代食物能否为北极熊提供足够的营养,弥补不能进食海豹带来的损失?
为了解开这个疑惑,皮尔福德及同事对西哈德逊湾荒野地区的北极熊在无冰季期间每天失掉的体重进行了估算,从表面上看,北极熊在这段时间食用了陆地食物。随后,他们将这一数据与通过马尼托巴北极熊预警计划暂时捕得的北极熊所失掉的体重进行了对比。
在被关期间,北极熊不吃东西。它们的体重每天大约下降1公斤。虽然野生北极熊能享用北极“小吃”,但是它们的体重每天也同样会下降1公斤。这一研究结果发表在《生理学和生化动物学》期刊上。
“显然结果表明,陆地食物不能为北极熊提供足以抵消大量损失的能量。所以,北极熊可以从食用海冰下面的食物转向食用陆地食物,并帮助它们对抗日益延长的无冰季这个观点,并没有在这项数据中得到证明。”
问题是,北极熊进化成了依靠海洋食物的动物。
“陆地食物以蛋白质和碳水化合物为基础,而北极熊需要的食物以脂肪为主。脂肪是这些熊真正需要的东西;它们高度适应的情况是,将脂肪吸收进它们的系统中,然后把这些脂肪放在身上以增加体重,这样它们之后就可以依靠这些脂肪来度过禁食期。唯一能提供给北极熊这种脂肪的就是海洋哺乳动物。但是它们只能在有海冰时食用到这些海洋哺乳动物。”
成年北极熊可以8个月不进食。但是小一些的未成年北极熊已经不再被哺育,它们必须要去猎食,可是它们不能在漫长的无冰季期间一直不进食。所以,随着北极地区变暖,较小的北极熊将会大批死亡。这使这些物种的生存成为问题。
