宜昌市林业局三峡晚报《金周刊》

nimals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.

Why should people care? Because we need animals, and because once they are gone, there will never be any more. Animals are more than just beautiful or interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks, the farmers stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.

Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animal or planton the danger list. Slowly, the number of some animals in danger is growing.

动物是自然资源，在整个历史过程中，人类一直在糟蹋着这种资源。人们杀死动物，获得它们的皮毛，把它们当作食物或运动方式，或者只是因为它们碍事。成千上万种动物已经从这个地球上永远地消失了。现在另外上百种动物也上了濒危动物名单。仅荚国大概就有170种被认为处于危险当中。

为什么人们应该感到担忧呢?因为我们需要动物，因为它们一旦消失，就永远不会再出现。动物不仅仅是漂亮或有趣。它们不仅仅是人类的食物来源。在维持自然平衡中，每种动物都有其作用。毁灭某种动物会导致许多问题。比如，农民们如果杀死为数众多的鹰，他们谷物和粮食的仓库就会受到老鼠和田鼠的破坏。 为什么?因为鹰吃鼠类，没有鹰控制它们的数量，鼠类就会迅速繁殖。

幸运的是，有些人正在努力帮助拯救这些动物。有些组织筹钱以便人们了解这一问题。他们也努力使政府通过保护濒危动物的法律。很多国家已经通过了法律。这些法

律禁止杀害濒危名单上的动植物。某些濒危动物的数目正在慢慢地不断上升。

Nowadays environmental protection has become the first thing we have to do, because now the earths environment is under threat.

Now, we know that the earth has been warming, cold place has melted the ice, the water level becomes more and more high, let many coastal countries. More land desertification, disasters are hit, make our life is no longer so carefree.

First of all, we must start from the side.

Forests have been cut down, automobile exhaust emissions... The first will directly affect our lives, because they let we dare not breathe. So, the best way to deal with these problems is to drive less, ride bikes, and riding a bike is good for you! . But although it has been said that and said more than once, but why there are so many cars on the road? So, this method really, a bit not practical.

The simplest is to plant trees, the trees are humans good friends, they can help mankind to many things, such as clean air, and so on. So, a variety of trees, this method is very practical!

In short, our earth wanted us to take good care of yourself, to protect, want to use practical actions to help the earth, make the environment more beautiful!

先如今环保已经成为了我们必做的事，因为现在地球上的环境正受到威胁。

现在，我们知道地球已经开始变暖，寒冷地方的冰已经开始融化，变成的水使水平面越来越高，让许多沿海的国家被淹没。更多的土地沙漠化，天灾不断来袭，使我们的生活不再那么无忧无虑。

首先，我们必须从身边做起。

大片森林被不断砍伐，汽车尾气不断排放……这些首先就会直接影响到我们的生活，因为这些让我们“不敢呼吸”。所以，这些问题最好的解决方法就是少开车，多骑自行车，而且，骑自行车也很有益身体健康!。可虽然一直这样说，而且说了也不只一次，可为什么还是有那么多的车在路上呢?所以，这个方法实在，有点不实用。

最简单的就是种树了，树是人类的好朋友，他们能帮助人类许多事，比如净化空气啦，等等。所以，多种树，这个方法很实用!

总而言之，我们的地球要我们自己去爱护，去保护，要用实际行动来帮助地球，让环境更美好!

The passage mainly tells us the importance of protecting traditional Chinese culture, which is challenged or facing extinction because of the developing society and changing lifestyle. Besides, China is nationwide sparing no efforts to do it.

The protection of national and folk culture is of great significance to Chinese cultural diversity and also to the harmonious development between local economic and social development. It is reported that the Guangdong government pays special attention to protecting Chaoju，a local drama born in Chaozhou in the eastern Guangdong province.

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

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

Through observation, I found that plastic bags on peoples harm and pollution is very large. People often use plastic bags: mother to buy food and plastic bags; to shopping malls with plastic bags; in the restaurant to eat rice is also packaged with plastic bags to take home; even I buy stationery also with plastic bags. People do not know what they do to the environment caused by pollution, their own body caused any harm. Such as: people often put useless plastic bags thrown into the garbage, plastic bags in the rubbish will be smelly, so that the pollution of the air. People also throw plastic bags anywhere, a wind, plastic bags flying in the sky, the branches also see the tree is a plastic bag, and even the river there are plastic bags. This plastic bag in addition to pollution of the air, but also polluted our water resources.

We should raise peoples awareness, tell us the neighbors and friends and family together to beautify our environment. On the road to see the plastic bag quickly picked up, immediately took it to the garbage disposal. We want to start from my use less plastic bags, so that my mother every day to buy food or shopping when they first take their own bags, this is not very environmentally friendly? Or can use their own holding things as far as possible by hand, no plastic bags.

As the saying goes: "to protect the environment, everyone is responsible" We have to protect the home environment out of a force.

11(Sth.)are bound to generate severe consequences if we keep turning a blink eye to them.

如果我们继续睁一只眼闭一只眼的话，……一定会有恶劣的后果。

保护野生动物就是保护人类自己。由于坏境的恶化，人类的乱捕滥猎，各种野生动物的生存正在面临着各种各样的威胁。近100年来，物种灭绝的速度已超过了自然灭绝速度的100倍，现在每天100多种生物从地球上消失。我国也已经有10多种哺乳类动物灭绝，还有20多种珍稀动物面临灭绝。而它们的灭绝会导致用于制造新药分子归于消失，还会导致许多有助于农作物战胜恶劣气候的基因归于消失，甚至引起新的瘟疫。由此所造成的损失是我们永远也无法挽回的。

《中华人民共和国野生动物保护法》规定珍贵、濒危的陆生、水生野生动物和有益的或者有重要经济、科学研究价值的陆生野生动物受国家法律保护，所以滥食野生动物是违法行为。

国家一级重点保护野生动物有96个种或种类，如大熊猫、金丝猴、中华鲟等。国家二级重点保护野生动物有160个种或种类、如猕猴、黑熊、金猫、黄羊等。

但是，人类猎杀野生动物的现象还在不断发生。有些人杀了大象，把大象的象牙给拿下来，做成象牙制品，赚取高额利润;有些人猎杀老虎，把老虎的虎皮的刨了下来，做成虎皮地毯，老虎的骨骼泡虎骨酒;有些人猎杀藏羚羊，用它的毛皮做围巾;还有些人猎杀动物做美餐……正是由于人类毫无顾忌地大量猎杀野生动物，才导致不少的野生动物灭绝和濒临灭绝。

动物和我们人类一样，也是这个地球上的一份子，如果我们不计后果，继续乱捕滥猎，将会引来新得灾难，2003年的非典病毒流行，不就是一个典型的事例吗?所以，我们应该立即行动起来，禁止猎杀野生动物，保护它们，让他们和我们人类同在一片蓝天下和睦相处吧。最后，我要大声呼吁：保护野生动物，人人有责!

在地球上，除了人类，还有什么呢?没错，还有动物。可几年下来，动物的数量逐渐下降。人类有没有把动物当朋友看呢?

动物和人类应该是好朋友，可为什么动物会和人类为敌呢?是因为人类没有把动物发在眼里。比如奶牛。人类用奶牛生产奶牛，可等奶牛没有奶的时候，人类就会把奶牛残忍地杀死。奶牛没奶时，不会将它放生吗?奶牛也是一条活生生的生命啊!近几年的“鼠疫、艾滋病、疯牛病、禽流感”，这些都是动物们奋起反击的预兆呀!难道人类还要打第三次世界大战吗?我们的祖先就是高级动物呀!如果人类再不制止这种滥杀动物的行为，是对我们的地区母亲沉重的打击呀!

我们现在不要再破坏动物的家园，这样动物们就可以安心繁殖后代。朋友们，还动物们一片蔚蓝的天空，让小鸟自由地飞翔;给动物一片绿草地，让牛羊欢快地奔跑;还动物一片汪洋，让动物无忧无虑地畅游海洋之中。也许，这样可以安抚动物们受伤的心灵。动物原本不坏，只是人类破坏它们的家园，这些只是它们对人类的“报复”而已。

朋友们，让我们一起保护动物吧!

As time goes by, man is making the earth sick. People cut down too many trees and leave rubbish everywhere. Factories let out their waste without doing anything to it . This has caused some serious problems. Such as the land is sandy, the river is dirty, the air is less clean, even the temperature of the earth is rising. What should we do to save the earth ? My suggestion is that we should plant more trees, put rubbish into dusbins and stop factories (from)pouring waste directly into the air or rivers. In all, we have only one earth, we should do our best to protect it, or we will regret.

My favourate animal is panda.i think panda is the cutist animal in the world.It has black and white fur and especially it have black fur around eyes which looks like wear a pair of sunglasses.Panda likes banboo shoots and leaves a lot.I saw panda ate apply and cakes in Zoo before,but I know in nature world they would not eat these things.Now almost everyone in the world love panda,but only China has panda.So as a Chinese I feel proud to be born in a country has panda.

今天，我和朱芷懿、洪舒阳、王达开，以及一些亲朋好友去杭州旅游，目的只有一个：杭州野生动物园。

经过四个多小时的颠簸，我们到达了杭州野生动物园。我们跟着旅游团，看到了数量繁多的野生动物：高大威武的百兽之王老虎、眯着眼睛老想睡觉的狮子、身手敏捷的豹子、阴沉老练的狼、魁梧怪异的大猩猩、憨态可掬的小狗熊，还有马、牛、马鹿等等，令人目不暇接，但我看来，最厉害的还是大象，它身材最高，跑起来虎虎生风，连地面都传出颤抖的声音。

最好玩的是和大象照相，我坐在象背上害怕极了，生怕它把我掀到地上，瞧着大象比墙还高的身姿，我哪受的了?照完像后，我猜小心翼翼的赶紧下来。

别笑我胆小哦。如果你来试一回，就知道了。

现在我明白了，野生动物是地球的生灵，它们和人类一样，都是地球上的居民。所以我们要保护也是动物。

在这个世界上，每一分钟都会有许多动物由于人类的捕杀而失去了生命。

无论天空、陆地还是海洋，只要有人类到达的地方就会有杀戮。人们为了一碗美味的鱼翅汤而大肆捕杀鲨鱼，使鲨鱼的数量急剧减少。但据科学家说，鱼翅的营养成分还不如一个鸡蛋高。不仅如此，人们还会用一种极端残忍的方法来捕杀它们。人们把鲨鱼打捞上船，用铁棒将它们打晕，割下鳍后，又会被无情地丢进大海，被人割了鳍的鲨鱼，由于无法游动，鲨鱼也没有鱼鳔，只能沉入海底，孤独地死去。当我看到那些没有了鳍的鲨鱼用尽力气，用自己仅有的尾巴拼了命地左右摇摆时，我情不自禁地想问：这些渔民还是人吗？动物也是一条生命呀！这些人怎么能如此残忍地杀害它们呢？

对于我们人类来说，看可爱的海豚表演是一件愉快的事情，可是在这精彩的表演背后，却是一幅血腥的景象。由于海豚对声音极为敏感，很小的声音对它们来说已经是震耳欲聋了。人们就利用这一点来捕杀海豚。人们故意在海中制造出很大的声音，把几百只海豚逼到一个岸边，然后放一张大网把上百只海豚困在里面，让驯养师来挑选海豚。如果被挑选上了就会被驯养师带走，而没被选上的海豚则被罪恶的鱼叉叉死，眼前是一片血海。人们为了赚到钱又把杀死的海豚送到海鲜市场去卖，供人们享用。被挑选上去演出的海豚也会很痛苦，在它们表演时，听到人们的掌声和欢呼声时会让它们产生极大的心理压力，最终它们会由于心理压力过大而选择死亡，所以人们会在表演过后给它们打针，让它们缓解压力，而海豚表演不是为了食物而是为了一针药剂。

鲨鱼游过了五湖四海，也没游出人们的餐桌；海豚翻过了惊涛骇浪，却没能翻过人们的渔网。通过这几件事我知道了，其实最残忍的动物就是人类。动物的今天也许就是人类的明天。我们不仅要热爱自己的生命，也要关爱动物的生命。我们应少喝一碗鱼翅汤，就能多救活一条鲨鱼；少看几场海豚表演，就能使海豚减轻不少压力。动物也有生命。请记住，这个蔚蓝色的星球不单单属于人类。

你了解一些处于危险的动物吗?为什么他们处于危险之中?

我想世界上有许多处于危险之中的动物，例如老虎、熊猫.当农民们砍倒了树木，老虎不再能够隐藏和猎食，许多老虎被那些用毛皮换钱的人们杀掉.而且几乎没有地方供熊猫生存.在这个世界上，我们不是孤立的.如果我们的周围没有那些植物和动物，我们的人类就不能够生存.因此，保护野生动物是非常重要的.我们必须采取一些措施来保证植物不被毁坏，停止杀戮动物.如果我们每个人能够种植一棵树、建造一个鸟巢，世界将是非常美好的，这件事情很简单但是很有用的。

[英语作文：为什么我们应该保护野生动物

ear classmates,

As we know, some animals are dying out for various reasons. There is no doubt that animals are our friends. With World Animal Day coming near, what should we do to protect animals?

First of all, we should forbid people’s killing animals at random. Second, we should do all we can to protect animals’ living environment. With their living environment destroyed, the animals will become extinct sooner or later. Third, we should try our best to make everyone realize the importance of protecting animals. In a way, protecting animals means protecting ourselves.

Dear classmates, let’s start now and make every effort to protect animals—our good friends!

Environmental problems are being more and more serious all over the world。

For example， cars have made the air unhealthy for people to breathe and

poisonous gas is given off by factories。 Trees on the hills have been cut down

and waste water is being poured continuously into rivers。Furthermore， wherever

we go today， we can find rubbish carelessly disposed。 Pollution is， in fact，

threatening our existence。

The earth is our home and we have the duty to take care of it for ourselves

and for our later generations。 Fortunately， more and more people have realized

these problems。 Measures have been taken to cope with these problems by the

government。 Laws have been passed to stop pollution。 I hope the problem will be

solved in the near future and our home will bee better and better。

Animals are humans good friends, everyone has their favorite animal, you guess what I like best? Might as well to listen to me first a description, smart you can guess. It is brown, red, red bottom, dark and liquid of small eyes, long tail, a bit like with people, its like to live in the tree, you please it down it is not willing to? Ha ha, said along while, you must guess what animal it is? It is naughty cute little monkey.

Remember once my parents and I go to Shanghai Zoo to play, because I too like to wait, so the first place to play is the monkey hill. Nice to see so many monkeys, straight up. I want to play play them, so he picked a leaf and put in the cage next to dangling, and I didnt think a monkey saw this, quickly rushing down from the monkey mountain, jerked my hand up the leaves away. I didnt think it would be so fast, I startled the defenseless. Before I could react, it has been chewed up the leaves in your mouth. But didnt chew two times, all spit it out, as if to say: "bad, really bad." Also made a face at me, we immediately the funny looks amused by it burst out laughing.

动物是人类的好朋友，每个人都有自己喜欢的动物，你们猜猜我最喜欢什么?不妨先来听我描述一番，聪明的你就能猜到了。它一身棕色的毛，红红的屁股，乌溜溜的小眼睛，长长的尾巴，跟人有几分相似，它喜欢生活在树上，你请它下来它还不乐意呢。哈哈，说了半天，你一定猜到它是什么动物了吧?那就是调皮可爱的小猴子。

记得有一次我和爸爸妈妈一块儿去上海动物园玩，因为我太喜欢候子了，所以第一个去玩的地方就是猴山。看到这么多的猴子，我也高兴得直蹦。我想耍耍它们，于是就采了片叶子，放在笼子旁边晃来晃去，没想到一只猴子看见了，飞快地从猴山上冲下来，猛地一下就把我手中的树叶抢走了。我没料到它的动作会这么快，把毫无防备的我吓了一跳。没等我反应过来，它已经把叶子放在嘴里大嚼起来了。不过没嚼两下，都吐了出来，好像在说：“难吃，真难吃。”还对着我做了个鬼脸，我们顿时被它那滑稽有趣的样子逗得哈哈大笑起来。

What kind of environment should be? Ought to be beautiful, but also should be to let people feast for the eyes, but now all of you take a look at the environment, beautiful? Let people feast for the eyes? The answer is no.

So what should we do? Today, Ill give you some advice to protect the environment, the content is as follows:

We live earth is deteriorating rapidly, did we have to pay attention to their own living environment cause harm to nature, you must not throw sundry, especially those serious pollution of garbage, waste batteries, for example, because the section waste batteries contain heavy metals, if flow to clean the water, it is very much pollution, then try to save trees made items such as paper, pencils, because waste these things is the destruction of the forest. Also try to use less disposable lunch box, chopsticks and plastic bags and other items, so as to avoid unnecessary waste and reduce waste.

There are some tips: walking to closing the master switch, in order to avoid electrical appliances overheating explosion, a waste of money and waste of electricity, save water, to shut the tap when brushing your teeth, wash dish water to rice, rice water to water the flowers, wash water can sweep the floor, so we can reduce some waste. 12 dont hunt wild animals, animal protection is absolutely cant kill, but dont kill the common animals such as frogs, because frogs eat 15000 bugs for us, and most are pests. Some people often dont think that is, the stubborn still, so we should try to eat less wild animals, lead to wild animals, the drop in sales no longer killing of wild animals.

Our forest is called oxygen plant, so to take good care of flowers and plants, not to destroy the city greening, and actively participate in. But also to cut down trees less, dont waste wood items, because waste these things is to destroy the forest, so be used sparingly, to protect the forests of less and less.

Use energy-saving lamps to replace the ordinary light bulb, although some expensive but can use less electricity. I appeal to you: in our daily actions to protect earths environment, let our children and grandchildren live in a beautiful environment!

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。

In my mind，nothing can delight me so much as caring for animals.

Wherever I go and whatever I do, I usually keep in mind that animals are angelsfrom the heaven, which bring us endless comfort and pleasure.

I have been apanda lover since my childhood.

Panda is so lovely that brings fun to peopleand they are regarded as the treasure of our country.

Unfortunately，such a rare species is now faced with the danger ofbeing extinct。What I am eager to do is to raise people’sawareness of animal protection and appeal to more people to care for our earthcompanies.
