We should protect it, not hurt it. But some hotels are also sold the frog meat? Once, dad and his friends took me to dinner. A waiter said: "you see, this is we store the launch of new specials, stir flogs ball". "Chicken is what ah?" I curiously ask, "chicken is the frog." The waiter said, with a smile. I was very angry, because they hurt our good friends-frog! Another thing, he makes a big inspiration. One day, when I finish school, saw a man at the school gate at little chicks must sell, and I will have mercy on them. Because the little chicks must first came to this world, away from the mother, away from the mother love and mother warm embrace, and this is what they faced starved to death, the risk of freezing to death. At that time I thought: we humans are so happy! When you see here, did you see to protect our human friends-animals!

小朋友,你们抓过小蝌蚪吧,你们一定知道蝌蚪长大要变成小青蛙,青蛙可以吃害虫,所以青蛙是我们人类的好朋友。我们应该保护它,而不是伤害它。 可是有些饭店还卖青蛙肉呢。有一次,爸爸和他的朋友带着我去吃饭。一位服务员过来说:“您看,这是我们店新推出的特色菜,爆炒田鸡球”。“田鸡是什么 呀?”我好奇地问,“田鸡是青蛙。”服务员笑着说道。我当时很气愤,因为他们伤害了我们的好朋友——青蛙!还有一件事,他对我有很大的启发。一天,我放学 的时候,看见一个人在学校门口卖小鸡仔,我好可怜它们。因为小鸡仔刚来到这个世界上,就远离了妈妈,远离了母爱和妈妈温暖的怀抱,这也使它们面临着饿死、 冻死的危险。当时我想到了:我们人类是多么幸福啊!当你看到这里时,你是不是明白了要保护我们人类的朋友——动物呀!

We need to protect wild animals, because we protect wild animals, wild animals will be very friendly to us.

Like the swallow, swallow can help us to eat the pests in the field. If we human beings killed to catch them, they will eat mosquitoes that often to scratch faze us, let us better life? Without the swallow around us become many insect pests, these pests have great harm to our human!

I have an example. For example the frog, the frog can also help us to eat the pests in the field, can be said to be the police in the field. Once we kill them, not the frog, the pests in the field more and more, pest constantly eat vegetables, dont we will have a good harvest?

I have an example. Such as w, w is a doctor in the forest, it can help us to eat the pests in the tree, the tree back to health. We killed them, pests will be more and more trees, trees will slowly decrease. No trees on earth, floods, earthquakes.

My last an example. Such as owls, catch rats, the owl is good for us human beings, human is often hunt them. No owls, voles will increase. Rats ate the crops and vegetables is more, we human beings did not have a good harvest.

So, we need to protect more than animals. At the same time, we also need to protect other wild animals!

我们要保护野生动物,因为我们保护野生动物,野生动物对我们人类也会很友好。

比如说燕子,燕子能帮我们把田里的害虫吃掉。如果我们人类杀害捕捉它们,它们会吃掉那些常常来搔扰我们的蚊子,让我们更好地生活吗?没有了燕子,我们的周围变得很多害虫,这些害虫对我们人类有很大的坏处呀!

我还举个例子。比如说青蛙,青蛙也能帮我们吃田里的害虫,可以说是田里的警察。我们支捕杀他们,一旦没有了青蛙,田里的害虫越来越多,害虫不断地吃菜,难道我们会有美好的丰收吗?

我还举个例子。比如说啄木鸟,啄木鸟是森林中的医生,它可以帮我们吃掉树里的害虫,让树恢复健康。我们杀害它们,树木的害虫会越来越多,树木会慢慢地减少。地球上没有树,会发洪水、地震。

我最后举个例子。比如说猫头鹰,猫头鹰捉田鼠,是对我们人类有好处的,人类却常常捕猎它们。没有猫头鹰,田鼠会增加。田鼠吃的庄稼和菜就更多了,我们人类一样没有好的收成。

所以,我们要保护以上的动物。同时,我们还要保护其他的野生动物!

Human beings are different from animals in many ways. One of the differences is the ability of human beings to build. It is true that many animals are builders. Birds make nests, and bees make hives. But no animal could build the pyramids or the Great Wall or the Eiffel Tower. The variety, size, and beauty of the structures built by human beings is simply unsurpassed.

Another difference is the ability of human beings to use intelligence. Many animals are probably more clever than we realize, but no animal has the ability to write, to reason, or to speak. Only human beings can invent computers, make use of solar energy. Only human beings paint, draw, compose music, and write poetry.

These are but a few of the differences between human beings and animals. It is our special abilities that give us power to affect the world for the benefit of all mankind. We should be thankful for those abilities and learn to use them in a more wise way.

Many animals are in danger of dying out. As is shown in the chart, we can

see the number of animal species decreases faster and faster and this trend will

continue. From 1980 to 2010, at least 1 million animal species have disappeared.

Worse still, more and more wild animals are in great danger. It is not a piece

of sensational news; it is a fact, a harsh reality. Unfortunately, we may not

see these animals in the near future.

From the second picture, we can find some reasons. Why is the number of

animal species declining year by year? Apparently animals have become victims of

fashion industry. Animal skin has been used to make fashionable clothes and

these clothes sell at a high price. So some greedy people begin to kill animals

in a large quantity. This irresponsible behavior not only breaks the balance of

nature but also endangers the living environment of human beings.

As far as I am concerned, something must be done to stop this illegal

action. We believe "no buying, no killing". First, we must make concerning laws

to protect these animals in danger. Second, we must take some measures to

protect animals effectively. Animals are our friends and part of our

environment. Third, we should raise peoples awareness to protect animals and

our environment. In this way, we can build a harmonious society and ensure a

sustainable development.

Animals 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 aloneare 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。

In Taiwan, because most people do not understand the importance of wildlife, the wildlife is in a poor situation. We Chinese are fond of eating anything delicious, so there are many animals killed by hunters. People enjoy eating tigers, bears, birds, and lions, so there are fewer and fewer birds flying in the sky and fewer and fewer bears running here and there in the forest. Instead, we often see them for sale at the market. How poor they are! And how cruel we are!

In my opinion, we should try every possible way to preserve wildlife. First, no one is allowed to hurt any wild animal. Second, the authorities concerned should punish those who kill any wild animal. Third, we should pay more attention to those endangered species to protect them from being eaten. If we can do so, nature must become very beautiful.

在台湾,因为大多数人不了解野生动物的重要性,野生动物是在一个贫穷的情况下。我们中国人喜欢吃什么美味,所以有许多动物被猎人杀害。人们喜欢吃老虎,熊,鸟,和狮子,所以有越来越少的鸟在天上飞,越来越少的熊在森林里到处跑。相反,我们经常看到他们在市场出售。他们是多么可怜!我们是多么残酷!

在我看来,我们应该尝试每个可能的方法来保护野生动物。首先,没有人可以伤害任何野生动物。其次,有关当局应该惩罚那些杀害野生动物。第三,我们应该多注意那些濒危物种保护其不被吃掉。如果我们能这样做,自然必须变得非常漂亮。

全文共 3755 字

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。

Everyday,they play with each other happily. One day,I couldn’t find them. I asked my mother: ”Where are they? ” My mother told me that She didn’t know. At last,I found them in the grass. They were very dirty. I was angry,but when I looked at their lovely faces,I was happy again.

I love my little rabbits,and they love me. They are my good friends forever.

从那天起,两只小兔子成为了我的好朋友。它们有两只小小的耳朵,红红的眼睛和一个又白又胖的身子。它们很了不起的。

每日,它们互相玩的很开心。一天,我找不到它们了,我问我的母亲,“它们哪去了?”我母亲告诉我她不清楚。最后,我在草坪发现它们。它们很脏。我很生气,但当我看到它们那可爱的脸,我又开心起来了。

我爱我的小兔子,他们也爱我。它们是我永远的朋友。
