不会爬树的猴子

森林里的猴子们都会爬树,可是这一天,森林里来了一只不会爬树的猴子

猴子群里顿时炸开了锅。大家议论纷纷,有的说:“这肯定不是一只猴子!”有的说:“猴子不会爬树,将来怎么才能摘果子呀?等着挨饿吧!”毛毛听了有些难过,就决定离群独居。他用砖头搭了一间小屋子,再用石头在房子四周堆了一堵两米高的围墙,还在墙上架了一把梯子,专门供自己爬进爬出。

为了不让自己挨饿,毛毛就决定找其他动物学习捕食的本领。他先找到了刺猬,问刺猬能不能教他挖花生。刺猬爽快地答应了。于是,他就开始学习了。第一天,他根本没有挖到花生。因为毛毛挖得又浅又小,所以一无所获。好心的刺猬就从自己家里拿了一袋花生送给了毛毛。第二天,毛毛仍不气馁,又来挖花生。他费了九牛二虎之力,终于挖到了一颗花生,高兴得手舞足蹈。第三天,他掌握了挖花生的技巧,一鼓作气,挖到了二十颗花生。后来,他越挖越多,终于把挖花生这项本领学会了。

毛毛又跑到小熊那里,让小熊教他捕鱼。小熊也一口答应了。第一天,他连鱼的影子也没看到,就从小熊家拿了一袋鱼回去吃。后来,他慢慢掌握了捕鱼的技巧,终于捕到了许许多多的又肥又大的鱼。小熊也为他感到高兴。

后来,毛毛习得了一身的本领,快快乐乐地生活在这片森林里。

大家都疑惑不解,为什么毛毛这么快乐?就跑去问毛毛。毛毛微微一笑,说:“有短处没什么要紧,只要勤于学习,我们肯定能有一技之长,就不愁吃喝了。”

我家养了一只可爱的小猫咪,它叫咪咪,它有一双炯炯有神的大眼睛,有一对灵巧的耳朵。

咪咪喜欢吃鱼,只要我喊一声:“吃鱼啦”,它就像闪电似的窜过来,用期盼的目光望着我,好像在说:“好主人,我饿了,快给我小鱼吃吧!”

咪咪真调皮,有一次,妈妈在打毛衣,无意中掉下一个毛线球,咪咪立刻跑过去,用爪子滚起毛线球来,弄得一地都是毛线,看着它那样了,真让人又好气又好笑。

篇3:高三年级英语作文:Be grateful for friends

It is a celebrating day. I got in touch with Michael whom I have been losing contact for one year.

It is really magic. I was searching online aimlessly yesterday when an idea struck me suddenly: since Ben can find out my secret by keying in my name in the search engines, why can’t I do so, either?

I intended to find out something about Ben in revenge in the first place, but soon extend my name list to a wider category. It was then that I recalled Michael suddenly.

We have lost contact since our last correspondence in my senior 3. He mentioned to me in his last letter that he was preparing for going to UK to further his education. I, shamefully, was too busy to reply his mail then. When I was recommended to ZJU and won the final freedom, I thought he had already been in UK so I had no idea where to write him.

I used to think that we would never meet again. However, when I browsed the entries about him, I found out excitedly that he is still in P.R.C.!!

Without a moment hesitation, I ran upstairs to my dorm and found out my old address book. Thank goodness, his home no was still there.

After 3 times calling with no answer replies, I eventually got him on the phone. He was more surprised than I could imagine that when I asked for his hp no he was too nervous to remember it. :P Hehe.

Life is enjoyable in moments such like this. Old friends meet again surprisingly, on a road of their own ways to their dreams. they look at the face of each other, and recognize the old pal. It is such moment that makes me feel grateful to life: whenever I set off for a new destination, I see I have friends in the same direction, with whom I won’t feel alone any more.

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。

狮子继续向前找食物,前面一只兔子蹦蹦跳跳地向它这边走来,他看兔子的耳朵像两把剑一样高高地竖在头上,心想:兔子会不会用她的那两把剑来刺穿我呢?狮子吓得连忙往后退,跑得不见踪影了。

大自然是人类最好的老师。从大自然中我们可以发现许多奇妙的现象。这些现象和我们的生活息息相关。

我从猫的身上得到了一个启示:为什么猫走路没声音?原来猫的脚掌上有厚厚的肉垫,走起路来不容易发出声音;猫走路的时候,脚是“点起”“点落”和轻起轻落,足跟软软的肉垫轻轻地落地,就不会发出声音。所以猫走起路来一点声音都没有。

我想发明一种像猫爪子一样的鞋子,下面有厚厚的棉花垫,这样走路就不会发出声音了。在医院里,护士们都穿这样的鞋子照顾病人,就不会打扰病人休息。

我们发现壁虎的手脚很有吸力,可以在墙上行走,也不会掉下来。我想发明一种像壁虎手脚那样的吸盘,携带起来很方便,只要有墙壁,就能吸在上面。这样妈妈在院子里晒被子、晒衣服,都很方便。还可以做成带吸盘的鞋子,人们穿上这样的鞋子,在刷油漆的时候,就不用搬梯子,可以在墙上自由的走动,也不会掉下来。

我以后要仔细观察身边的事物,多发明一些对人类有帮助的东西,让我们的生活变得更美好。

篇14: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。

此刻,窗外又响起了噼里啪啦的鞭炮声,这是人们告别旧年的恋恋不舍,也是人们对新年的美好憧憬。
