我家的小狗长得十分可爱,圆圆的脑袋上嵌着一双琥珀色的大眼睛。它有一条粉嘟嘟的舌头,到了夏天总是伸出一大截。它的四肢强壮有力,爪尖是白色的。真逗人喜爱。

小狗吃东西的时候它总是先用鼻子闻一闻,再用舌头慢慢舔。每当我把蛋糕、油饼放在手上,小狗不但很快地把它们吃掉,而且吃得津津有味的。

有一天,一只小黑狗啃着骨头,小狗马上窜上去抢。小黑狗一闪,让小狗扑了个空。接着,小狗猛地站起来,前爪前伸,身子后倾,尾巴一挺,“呼”地向小黑狗扑过去。小黑狗一声怪叫和小狗厮打。它们“汪汪”乱叫,蹿上蹿下。小狗看准时机,狠狠地把小黑狗的腿咬了一口,小黑狗惨叫了一声,一瘸一拐地夹着尾巴放下骨头溜走了。小狗趴在地上舔着身子,又津津有味地吃着“战利品”。

这样可爱、勇猛的小狗叫我怎么会不喜欢它呢?

它要是高兴,能比谁都殷勤,能比谁都温柔。它会冲你汪汪叫几声,或是蹭着你的腿叫你把它抱进怀里,轻轻抚摸它,它偎在你的怀里,静静地躺着,享受着你的爱抚,仿佛是个温顺的孩子。它还很善解人意,在你写作业的时候,它也不吵不闹,只是静静地趴在你身边,摇头晃脑地看着你,或者自己玩,就是不会打扰你;但它若是不开心,情绪不高,你叫它,它也不会理你,更愿意躲在一个角落里,蜷成一团,呼呼大睡;你若这时训它,它的小脾气一上来,就会跟你赌气,然后“离家出走”,出去一天也不见个影儿,让你挂念它。

亲爱的朋友们:

你们好!

当你漫步在绿树荫荫的森林,当你行走于青色一片的草茵,当你辗转于层栾叠峰之间……你是否想到如果能远远地听到“百啭千声随意移,山花红紫树高低”的鸟鸣,如果能见到穿梭于树中的小猴的身影,如果能遇到溪边饮水的小鹿……那么,大自然会多么灵动,多么迷人。

谁不向往静谧的田园生活?谁不渴望每天见到蓝天白云?谁不期待身边有鸟语花香?听着松涛低语,鸟鸣啾啾,看着苔藓绒绒,树叶飘飘,伴着流水潺潺,鱼儿嬉戏,人都会陶醉其中。

黑龙江省的野生动物资源是非常丰富的,但是由于生态环境的恶化、野生动物栖息地的人为破坏,致使我省野生动物的数量、分布范围正日益缩小,许多种类已处于濒临灭绝的状态。近几年,滥食野生动物的现象屡禁不止,使得许多已经处于濒临灭绝的野生动物的处境更加艰难。

1996年1月通过调查发现,到目前为止我省有野生动物476种。其中:爬行类3目四科16种两栖类2目6科11种、鸟类19目57科361种、兽类6目21科88种。分布在我省的东北虎、金钱豹、原麝等珍稀动物的分布区明显缩小、数量显著减少,而原在我省分布的镰翅鸡已确定在我省绝迹。可喜的是,这次野生动物资源调查又发现了中介蝮、黄腹山雀等21种生物在我省的新分布。其中:兽类1种、鸟类19种、爬行类1种。

为了人类共同生存的环境,为了这个星球上一切生物的未来,我倡议:

Ø  伸出我们的双手,每年种上一颗树;

Ø  做一名保护野生动物的积极宣传者:

Ø  提倡不食野生动物,树立饮食新风尚;

Ø  劝说、阻止伤害野生动物的人和事。

Ø  让我们行动起来,共同努力,从我做起,从小事做起;

Ø  让家乡的树更绿、天更蓝、水更美;

Ø  让大地处处充满生命的绿色;

Ø  让野生动物与我们人类在同一片蓝天下平安地生活。

Ø  争做文明、守法、有爱心的公民。

Ø  让大地处处充满生命的绿色;让野生动物与我们在同一片蓝天下平安地生活。

Save the Wild Animals

Many wild animals are facing the danger of extinction, because the environment that they are living in has changed greatly. For example, with the developmet of cities, the using of insecticide and serious pollution, their living areas have become narrowcr and narrower. Many of the wild animals, now are confronted with food crisis. At the same time, man is killing off species just for getting their fur, skin, horns, teeth and meat.

In order to protect our resources of ecology, people should realize that the loss of any species is at least the loss of source of knowledge and a source of natural beauty. There fore, measures of the following should be taken: pollution standards are made to keepdown poisons; killing off certain rare species is prohibited; national parks should be set up as wild life, reserves.

Only if we human beings take some drastic measures can wild animals be preserved.

保护野生动物

许多野生动物正面临绝种的危险,因为它们生活的环境发生了极大的变化。譬 如,随着城市的发展,杀虫剂的使用和严重的污染,野生动物的生活区域变得越来越狭小。许多野生动物目前正面临着食物方面的危机。同时,为了获取野生动物的毛、皮、角、牙齿和肉,人类正在屠杀野生动物。

为了保护生态资源,人们应当意识到任何物种的缺失,至少意味着知识资源和自然美的缺失。因此,应采取以下措施:制订污染标准以降低有毒物质;严禁杀害某些稀有物种;应建立国家公园作为野生动植物保护区。

我们只有采取一些有力措施,才能保护野生动物。

我爸爸从市场上给我买了一只小乌龟,我高兴极了。

这只小乌龟非常可爱。大大的龟壳,小小的脑袋,还有有力的四肢。让我疑惑不解的是小乌龟不胆小,我用手碰它的头,它也不肯把头缩回去。小乌龟全身碧绿,只有肚子比较白。眼睛比较小,它的眼睛一只睁着,一只闭着,我想它可能是生病了。

有一次,我给小乌龟换水,我把小乌龟拿出来,它却想把头伸过来咬我的手,我想它可能饿了,便让妈妈切一块肉,我就让乌龟把肉叼住,可是它咬住了并不往里吞,我觉得小乌龟比较笨。

我很喜欢我的小乌龟,我希望能让小乌龟多活几天,但不幸的事情发生了。

一次我给它换水,发现它一动也不动,我好奇的把小乌龟放在深水里,我想它应该会吐一个气泡,结果它没有吐气泡,还是一动也不动,我想它已经死了。

我很伤心,因为跟它在一起很好,我本来想让它多活一会儿,结果它却在今天死了。

我想人们有工夫养它(动物),就要好好养它,就不要放弃它。阳台旁边的一群猫

去年,在夏天,我在阳台晒太阳,忽然,我看见阳台前的花园出现几只小猫在玩耍,还有一只大母猫在放哨,我想这只大猫就是它们的妈妈吧。我把这件事告诉了妈妈,妈妈说:“你要喜欢的话,可以天天给它吃的,让小猫们还有大猫信任你。“我向妈妈要了一点牛奶还有剩的鱼拿去喂它。我刚走过去,看见猫早就没了,我只好把奶还有鱼放在两个盘子里,放在它们能看见的地方。不一会儿,那几只小猫还有大猫都出来了,是大猫先看见食物的,首先,它叫了几声,好像在说:“有人类给咱们食物了,快来吃吧。“小猫们立刻跑到食物跟前狼吞虎咽的吃了起来。它们一定好几天没吃了。

就这样,它们每天都来玩,来吃饭,日复一日,它们变胖了,它们已经跟我们熟了。

一次我在花园玩,忘了关门了,回来的时候,我发现家里有四只猫,,两只是花的,一只是黑的。我想去给它们挠痒,但是它们都走了,只有两只猫留下来,一只大灰猫,一只小花猫。一个月以后,只有一只常到我们家串门。

我想,动物们需要自由,不要把它们关在某个地方,要爱护动物。

Animals are our friends。But how to protect them? government is working to protect all animals in danger,and has made lots of plans to save animals。 On the other hand, we shouldn’t eat wild animals。We should keep them away from our dinner。 That way,there will not be wild animals on sale。 I think the hunters and killers will become fewer and fewer。

Last, we should protect the environment。We should stop people from cutting trees down。 Without trees, wild animals will lose their home。 And we will lose our animal friends。 All of us should try our best to protect animals。

We need to protect animals better。We should give them fresh water to drink。We should make the forests bigger for animals in danger to live in。We should advice people not to kill animals beacause they are our friends!

动物是人类的好朋友,好朋友是不能杀害的,我们应该竭力保护它们,何况现在它们已经越来越稀少了。

世界上有许多野生动物都濒临着灭绝的危险,这又是谁的错呢?人类,是人类!假如人类不去乱砍伐树木,动物们就不会“无家可归”;假如人类不对大自然下“狠手”,动物们也不会这么快消失的……人类吃野生动物,得了许多疾病;人类使一种动物灭绝,导致多种动物灭绝,人类也就受到印象。总之,肇事者是人类,最后的受害者也是人类。

在南京大屠杀中,许多被保护的羚羊惨遭厄运;现在东北虎的生存空间已经不够,人类破坏了它们的家园;大熊猫是人类皆知的动物,虽然它们过着“衣来伸手,饭来张口”的生活,可有谁能预测它们还能活多久呢?……种种“案件”表明罪魁祸首就是人类。

动物们是保护地球的一根根链条,就算它们不是珍稀动物、国家级保护动物,我们都有责任去保护它们,而不是破坏它们的生存空间。它们是支撑地球生命的铁环,如果这根铁环中少了一种动物,那链条随时可能断裂,人类也就随时会灭亡。到了那时,就算你再怎么有钱,再怎么有权,也挽回不了你的生命呀!小沈阳说的对:“钱乃身外之物”,你用你的钱财去吃野生动物的原因就是让别人知道你是大富翁。这样做就大错特错了,吃野生动物不仅对自己无利、对别人有害,国家还严刑惩罚呢!真是害人又害己呀!

让我们一起携手保护动物吧!它是地球母亲的孩子,同我们是姐妹,也是世界的一份子,还是我们的好朋友呢!你忍心杀害我们的好朋友吗?

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。

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?

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.

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。
