一日三餐，都要吃东西，而肉则是必不可少的，我们吃的大多数都是鸡鸭鱼肉，这些没啥大不了。可是一些珍稀动物也被摆上了餐桌，如鳄鱼，江豚，鲸等。

我们都是地球妈妈的孩子，又何必要向兄弟姐妹下此毒手呢？

其实大自然是一个相当复杂的食物链，里面的生物可谓缺一不可。缺了其中的任何一种都会早产极大的后果，就会乱了套。在此就举几个例子吧：

蛇，众所周知蛇是无足的爬行动物的总称目前全球共有3000多种蛇类。身体细长，四肢退化，无可活动的眼睑，无耳孔，无四肢，无前肢带，身体表面覆盖有鳞。部分有毒，但大多数无毒。蛇类中最毒的要数大洋洲的太攀蛇和内陆太攀蛇。它每咬一口释出的毒液已足够杀死100个成年人，最长的蛇要属网斑蟒它。

是人们知道的唯一体长达10米的蟒蛇。网斑蟒通常生活在热带的亚洲地区，依靠身体的重量缠死猎物，眼镜王蛇也应是大家较为熟悉的一种，是最长的毒蛇，喜欢捕食蛇。你们知道吗，在一些地方蛇已经成为了保护动物。你们知道吗蛇的毒液已被用来治疗一些不治之症。而且可以成为史上最强的麻醉剂。

再说鳄鱼。鳄鱼是迄今发现活着的最早和最原始的动物之一，它是在三叠纪至白垩纪的中生代（ 约两亿年以前）由两栖类进化而来，延续至今仍是半水生且性情凶猛的爬行动物，它和恐龙是同时代的动物，恐龙的灭绝不管是环境的影响，还是自身的原因，都已是化石；鳄鱼的存在证明它更加强盛的生命力。

被誉为活化石的他们已经越来越无法适应当前的环境了，仅存的23种中，有17大概种处在濒危状态鳄鱼全身都是宝，他们的皮可以做为鳄皮大衣，肉可以做成汤， 血清提取出来的胎蛋白将成为史上最强大的抗生素，甚至可以抗击艾滋病。这可谓是一项重大成功的发现。

啊！

朋友们，动物的大量毁灭对人类将产生严重的不良后果，造成生态环境严重不平衡，从而使人类的生存环境遭到破坏。消灭动物，就是在消灭人类自己，如果有一天世界上的动物全都消失了，那人类还能生存吗？要保护动物，珍惜这自然界里的每一个生灵吧！

让我们从现在做起，从我做起，保护动物，使世界变得更美好吧！保护动物，就是保护人类自己。

一年中有许多节日：快乐的儿童节、团圆的中秋节、热闹的春节……而我要设立一个与众不同的节日——保护动物节。

我从小就喜爱动物。常常吵着买动物书，去动物园，看到一只瘸腿的纺织娘都要伤心，吵着妈妈为你它绑纱布。每次，看到那些可爱、漂亮的的小动物，我就觉得他们真可爱，大自然有了它们真幸福。

那天，我兴致勃勃地收看《动物的生命》。电视中介绍着一个个有趣的动物，这些动物时而奔跑，时而争斗，时而戏耍……可是后来，我看到这样令我心惊胆战的一幕：一群非洲人正在追赶一只黑犀牛，犀牛拼命逃命。突然，一颗从天而降的子弹直射在犀牛的身上，一击命中，一个非洲人走过去，不顾犀牛的悲鸣，用一把匕首把犀牛的角切了下来。非洲人看了看手中的牛角大笑：“这一定能卖个大价钱……哈哈哈……”转身开车而去。我不忍心再看下去，眼前总是浮现起犀牛那无助的眼神，血肉模糊的脑袋。我不明白：“人类呀人类，为什么偏偏要杀死我们人类的朋友——动物，他们也有生命的呀?”突然，我的脑海里产生了一个强烈的念头——对了，我们要保护动物，灵机一动：应该可以建立一个保护动物的节日!

保护动物节来了，这天，每个人的心中都有着“爱护动物”的信念，哪怕一只小小的蚂蚁我们都可以投去爱的目光，那天饭桌上不能有肉类。大街小巷的电视屏幕上要循环播放保护动物的频和口号。大家在这一天要进行慈善捐款，成立“基金会”，用这些钱去建立自然保护区，大家还可以去动物园认养一只动物。好多同学都上街进行宣传保护动物，每个人心中都牢记保护动物的责任……

我真希望你也能支持我，让我们一起来保护动物吧!

今天，我一不小心看到了语文课本上面有一张图片，上面画了一个动物，但是是我从来没有见过的。于是我就跑去问妈妈，妈妈告诉我那是已经灭绝的动物。

听了妈妈的叙述，我想到了为什么那些美丽的动物会被灭绝。这是为什么了?是人类对大自然造成了破坏了，使得动物们失去了平衡，结果走向了灭绝吗?

我听说生活在海边的渔民们以捕鱼为生活，而且经常污染海洋环境。就连海洋的霸主鲸都受到了破坏，已经渐渐减少。鲸的繁殖能力本来就很差，平均两年才有可能生下一头幼鲸。但是由于人类过量捕杀和对海洋环境的过度污染，鲸的数量已经在逐年减少。在地球上鲸渐渐减少，如果在这样下去，相信不用几年，鲸也将灭绝。

这种情况不只是在海洋，陆地上面也同样有这种情况，在我国东北的陆地之王东北虎。由于虎皮保暖而且漂亮就成为了人们的围捕对象，人们大奖捕杀东北虎，而且同时还大量的砍伐树木，致使森林面积减少，而且导致东北虎的数量急剧的下降，现在东北虎越来越少，慢慢地快消失在人们的视野中。

看着这么多快要灭绝的动物，我想呼吁人们不要再残害动物破坏环境了!我们大家共同保护我们的家园吧!

Stress comes in all shapes and size, and has become pervasive, it seems to

penetrate everything and everybody, its hard to get through a day without

hearing or reading something about stress. Some doctors refer to stress as some

kind of new plague天灾, 灾害, 祸患. However, numerous surveys confirm that the problem

has progressively risen since the 1980s. Why all the disorder? After all, stress

has been around since Adam and Eve were in the Garden of Eden, Stress is an

unavoidable consequence of life. Without stress, there would be no life.

However, just as distress can caw disease, there are good stresses that balance

this, and promote wellness.

My name is Li Hua. I was born in the city of Dalian, Liaoning Province. I studied in Guangming Primary School from 1984 to 1990. Then I entered NO.6 Middle School where I mainly learned the subjects like Chinese, mathematics, English, physics, chemistry and computer. I have been very fond of and good at English and computer ever since. Therefore I placed first in the school computer competition last year. My hobbies include swimming in summer, skating in winter as well as collecting stamps and listening to popular music in my spare time.

看着变得越来越少的动物，濒临灭绝的动物越来越多，我们是不是应该开始保护动物，从我们身边的小事做起。

看了科普书《森林报》(春)后，我对大自然有了些认识，它让我爱上了蹦蹦跳跳的小白兔，喜欢上了警觉的松鸡，迷上了好斗的琴鸡，但我印象最深刻的是里面的小篇章——《打猎》。

它主要讲述了猎人们怎样打猎。如果猎人要打勾嘴鹬的话，会选择在黄昏时打他们，并会先打雌的(前提是一对勾嘴鹬夫妇)。这样雄的勾嘴鹬就会为找不到自己的妻子而发愁，这时，猎人就扔起自己的黑帽子。雄勾嘴鹬以为那是自己的妻子，于是就俯冲下来，这时，猎人再开枪把勾嘴鹬打死。

猎人们打野鸭也有自己的一套方法。他们先把捕捉到的野鸭训练成“叛徒”，然后把那只野鸭带到河面上，野鸭就会大声地叫，它的叫声吸引了众多野鸭，猎人就一枪一枪地把他们打死。

看完后，我觉得猎人们非常残忍。可转念一想，他们是为了生存而不得已这样做的。既然这样，还是从我们做起，开始保护动物吧。

现在，首先，我们尽量少吃那些用动物做成的菜啊，汤啊等等，否则就等于在杀害那些小生命。就拿鸭子来说吧，我大约算了一下，全中国最少也有几千个烤鸭店，而每天至少要卖出几十只烤鸭，这样每天就会死几万只鸭子，每年就会更多了，更何况这仅仅是中国的数子啊，要是全世界的数目就会更可怕的。其次，我们尽量不要捕捉小鸟，这样，它们可能会受惊，再加上没有朋友的陪伴，它们可能会闭上眼睛的。难道你忍心看着一只只快乐的小鸟就这样悲惨地死去吗?

让我们从自己做起，从小事做起，保护动物，保护我们的家园。

动物是人类的好朋友，我们应该爱护它们、保护他们，可有些人却把它们当成了玩具和盘中餐……

先说玩具吧，许多小朋友，甚至一些大人，每次买了宠物，像小猫、小狗、金鱼……养在家里，把他们像玩具一样捉弄、戏弄，我想说：动物也是一条生命!它们也是有尊严的!还有，养小动物如果一时疏忽，有时会把他们弄生病，甚至死亡!

再说盘中餐吧，许多大人喜欢吃野生动物，像青蛙、蛇……这样，使得许多动物都灭绝了!而且对人体也有很大的危害!据说2003年“非典”就是因为这样引起的!我诚恳的告诫大家：“请大家不要再吃野生动物了!”

还有，许多人特别爱吃青蛙，所以有许多人为了赚钱，残忍的杀害了青蛙拉到菜市场去买……请问那些杀害青蛙的人，你们在杀害青蛙的同时，有没有想过，青蛙是人类的好朋友，他们能帮农民伯伯捉害虫、保护庄稼呢?

动物是人类的朋友，请大家保护动物吧!保护动物，人人有责!

从小，我就特别喜欢动物，我总觉得他们和我们人类一样是有感情的，有思想的，所以，无论什么时候我都尽可能的与他们好好交流，用我微薄的力量关心爱护着它们。每次周末，只要时间允许的话，我都会和爸爸妈妈到郊外去郊游，说是游玩，在欣赏美景的同时，我们会给许多需要帮助的动物搭个窝，留点食，或者宣传宣传保护动物的意义。

又是一个天朗气清的周末，我和爸爸妈妈决定去郊游。我们就在动物园旁边的草坪上野餐。中午时分，阳光照在身上暖洋洋的，躺在青青的草坪上，感受着这郊外的鸟语花香，多惬意啊!我双手叠在脑后，眼睛眯了起来……

突然，动物园里传来了一阵响声，只见一只只动物一个接着一个浩浩荡荡地跑了出来。我顺着它们跑的路线跑过去，看见同一类的动物站在一排，而高高在上的是两只狮子。两只狮子一左一右地坐着，还戴着漂亮的皇冠。这时，两只狼士兵发现了我，把我推到了两头狮子的面前。原来它们是动物国的国王、王后。不可思议的是，我能听明白它们说什么。国王打量了我一眼，就认出了我，非常尊敬我，因为我是他们最尊贵的客人。接着让兔子侍女给我换了一件用百鸟的羽毛加下百兽的毛发编织而成的七彩衣。这一打扮我还觉得自己真美，我觉得自己就是一只金孔雀了。兔子侍女把我扶上了宝座后，所有的动物都向我请安，他们轮流感谢我提供给他们的帮助，希望有更多的人类能像我这样关心他们。我答应他们，一定让更多的人类来关爱动物。他们高兴极了，一起高高地举起了我，把我抛向空中，表示他们的热情。

我笑了，笑声在整个天空中回荡……这时，妈妈拍醒了我，问我睡梦中笑什么，我这才知道刚才是我的梦境。

we all know that the panda is a kind of lovely animals, but its behavior, some children are not completely know. In order to solve this mystery, recently I have made an observation about it.

The panda is a kind of precious animal, is very attractive. Its shorter in four rubber slow action. On the face of fuzzy embedded with a pair of black eyes. Combined with a black and white hair, more beautiful and lovely.

Pandas like to walk leisurely on the flat ground, play happily. Sometimes looked up people, sometimes low head, as if in search of something, and like to think. When it is happy, somersault on the ground, like a big ball rolling on the ground.

The panda when sleeping, belly up. Sometimes, patting his stomach with his front PAWS, sometimes, it push to the legs, was turned over. I thought it waked up, in fact, it is still in sleep. Waked up just turn it up, with his front PAWS rubbed his change to eyes, curiously at the people, with for she walked away to the other side of the fence to sit down, as if to clear his mind. (pupil composition nets)

When the panda eat, often straight body sitting cross-legged, PAWS grab fresh bamboo leaves to her mouth. It loves to eat fresh bamboo leaves, bamboo stem, and milk and eggs. Pandas eat and drink drink throat. It came to the pool, fell down, the ball pool, lower the head, plump plump to drink up. See the face of it, really makes people laugh.

The panda is one of the worlds rare animals, is a darling of the zoo. Its every move, add fun to tens of thousands of visitors.

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。

"Bumper harvest, bumper harvest!"!" Cried one of the fishermen, happily jumping up like a child. After a while, the full cabin fish alive and kicking, calm sea filled with coming from all sides of the fishermens laughter.........

Now, like this "fish and shrimp full cabin" scene has been very rare. In todays market, is the most common fish pound at least to dozens of yuan, more serious pollution of the ocean, the ocean resources gradually dried up, seafood production, prices rise, it illustrates this point?

In the ocean of natural calamities and man-made misfortunes emerge in an endless stream today, human pollution is often not from the original intention, but it is caused by the unexpected effect. The British Petroleum oil, because the drilling platform explosion, caused by the oil spill in the Gulf of Mexico, to 9900 square kilometers of sea water is seriously polluted, so that tens of thousands of seabirds soaked in oil to move, die in hunger and misery, makes countless fish poisoning death; and the Japanese earthquake and tsunami triggered a nuclear leak the marine pollution is more serious......

The sea is so vast that it is because the rivers and streams flow into the Yangtze River and then run into the sea. If we do not solve the pollution problem from the source, then no matter how people clean up the sea, there will always be sewage flowing into the sea, and all the efforts will be futile. Now, streams and streams are often seriously polluted, or they become places where people dump rubbish or are loaded with pesticide cans. Finding a clear stream in an inhabited area can be very difficult today!

In any case, the protection of the oceans can not be achieved by individual forces, and the protection of the oceans depends on the joint efforts of all mankind. I do not want one day in the future, our descendants can only imagine the image of the vast and wide sea.

This is not only the wish of a pupil, but also the wish of all mankind, isnt it?

Dear editor,

I know on your school English newspaper that the readers are expected to have a discussion on the topic of protecting Traditional Chinese Culture. The protection of national and folk culture is of great significance to Chinese cultural diversity and also to the harmonious social development. I have a strong desire to share my personal viewpoints on it.

In my opinion, some measures should be taken to protect traditional culture effectively. To begin with, we should make a law to regulate the society’s performance. What’s more, we should draw more people’s attention to it, for the more they know about the importance of culture protection, the stronger support we can get from the public.

In a word, it is high time for us to treasure and develop our own valuable culture.
