篇1:保护濒危动物英语作文附翻译

In the past, there have been many endangered animals. Now they are extinct. Does it matter? Has our environment been affected by their absence? Has the quality of our own life been changed? The answer to these questions is "Yes."

Yes. It does matter if we destroy an endangered species habitat to develop more farmland, housing or industrial parks. There is a delicate balance of nature. If one small part is removed, it will effect all the other parts. For example, if certain trees are cut down, bats will have no place to roost. If they cannot roost, they cannot breed. If there are no bats, there will be no animal, or bird to eat certain insects that plague our crops.

Yes. Our environment has been affected by the absence of certain animals. Certain flowers are pollinated by butterflies, which migrate from Canada to Mexico. Some of the breeding grounds of these butterflies were destroyed. Now these flowers are disappearing from certain areas. We will no longer be able to enjoy their beauty.

Yes. The quality of our life has been changed America used to be covered with giant trees. Now we have to visit them in one small park. Rain forests around the world are being cut down to make room for humans. We will never be able to see or study this fragile ecosystem.

I would encourage us humans to look for other alternatives for our farmlands, housing, and industries. We have alternatives; the animals do not.

在过去,有许多濒危动物。现在他们正在灭绝。关系呢?我们的环境已经受到他们的缺席?我们的生活质量已经改变了吗?这些问题的答案是“是的。”

是的。没关系如果我们摧毁一个濒危物种栖息地开发更多的农田,房屋或工业园区。有一个微妙的平衡。如果一小部分被删除,它将影响所有其他部分。例如,如果某些树木砍伐,蝙蝠没有栖息的地方。如果他们不能,他们不能繁殖。如果没有蝙蝠,不会有动物或鸟吃某些破坏庄稼的昆虫。

是的。我们的环境已经受到缺乏某些动物。某些花授粉的蝴蝶,从加拿大到墨西哥迁移。一些这些蝴蝶被毁的繁殖地。现在这些花从某些地区消失。我们将不再能享受他们的美丽。

是的。我们的生活质量已经改变了美国曾经覆盖着大树。现在我们要拜访他们在一个小公园。世界各地的热带雨林被砍伐,为人类。我们将永远无法看到或学习这个脆弱的生态系统。

我将鼓励我们人类去寻找其他替代品对于我们的农田,住房,和行业。我们选择;动物不会。

Perhaps, everyones heart has their own favorite animals, small to cats, dogs, big to elephants, pandas, giraffes, but, I like animals or insects, small to not see dont see, it is the most easily neglected but a large number of ants.

The ant is a kind of like social insects, dont look at it, but it has a "strong man" title. An ant can lift 50 times more than their weight. 2 times people if can move up the weight of everything is wonderful. People who want to really dust and ants than strength.

Previously, I have heard, the ants are very united, I also saw, in the ant mouth, many ants against a live common caterpillar, thought, and the mere survival needs, hunting together, a lot of animals wolves hunt, hyenas are so common, no surprise. So many ants have thinking every day together, cant afford to infighting just strange!

Later, I saw an article, let I to small awestruck by ants. This article writes: a group of ants meet fire, they didnt panic, immediately transform into a group of formations, these can keep the queens, young ants race survival ant package in the middle, rapid rolling a ball of fire, break through in the direction of the river, outer ant ant regiment repeatedly heard burned after the burst of noise, but not to reduce the ant regiment. Obviously, this outer "ant kingdom hero" by the burning to death also dont loose fraction, courage all crack dont give up their jobs. And in a short while, ant group rushed into the river, as to the other side of the scroll, the river rose a thin layer of smoke... Any creature that has a survival instinct, small ants can in a survival situation, continue to race, choose to sacrifice myself, what a respectable!

Compared with the unity of ants, we should be ashamed of yourself. Sometimes because of the little things, and her classmates went red, shouldnt have. Originally in the world, noble and great really has nothing to do with size, strength, what really matters is strong in spirit, if we have ants so closely united, dedicated spirit, what we cant finish?

也许,每个人的心中都有自己最喜爱的动物,小到小猫、小狗,大到大象、熊猫、长颈鹿,可是,我喜欢的动物或者说是昆虫吧,小到不仔细看根本看不到,它就是最易被人忽视的却又数量庞大的蚂蚁。

蚂蚁是一种喜欢群居的昆虫,别看它微不足道,但它却拥有“大力士”的称号。一只蚂蚁能搬起超过自己体重50倍的物体。人如果能搬起自己体重2倍的东西都很了不起了。人要和蚂蚁比力气可真是望尘莫及。

以前,我曾听别人说过,蚂蚁们十分团结,我也亲眼见过,在蚂蚁洞口,众多蚂蚁共同对付一只活毛毛虫,心想,那只不过是生存需要,共同猎食罢了,好多动物像狼、鬣狗都是这样共同捕食,不足为奇。这么多有思维的蚂蚁天天在一起,不起内讧才怪呢!

后来,看到了一篇文章,让我对小小蚂蚁肃然起敬。这篇文章写道:一群蚂蚁遇到火灾,他们没有惊慌失措,立刻变换队形扭成一团,将蚁后、幼蚁这些可以维持种族生存的蚂蚁包在中间,迅速滚过火球,向河岸方向突围,蚁团不断发出外层蚂蚁被烧焦后爆裂的声响,但是蚁团却不见缩小。显然,这外层被灼焦的“蚁国英雄”们至死也不松动分毫,肝胆俱裂也不放弃自己的岗位。一会儿,蚁团冲进了河流里,随着向对岸的滚动,河面上升腾起一层薄薄的烟雾……但凡生物,都有求生本能,小小蚂蚁却能在生死关头,为了种族延续,选择牺牲自己,多么可敬啊!

和蚂蚁的团结比起来,我们应该感到惭愧。有时因为一点小事,和班里的同学就闹得面红耳赤,真不应该。原来这个世界上,崇高与伟大真的与个头、力量没有关系,真正重要的是精神上的强大,如果,我们具备蚂蚁这样紧密团结,勇于奉献的精神,还有什么事情我们不能完成呢?

This afternoon, I turned on the computer on the qq, and saw in qq space "simply make the gods cry".

Some people are ready to take the little bears bile. At that time, break the cage, a mother bear with huge PAWS strangled little bear, then her head hit the wall and died. Maybe it is their best way to them, because they are relieved.

After I read this story, I almost cry. So cute teddy bear, so the great bear, who is cruel killed them? Is human. Who is the one who claim to protect giant pandas? As humans. This is not a contradiction? The giant panda is a national treasure in our country, but as soon as I saw some pandas humans want to flee. Why is this? Because someone hurt the panda.

The panda is so cute! They also have life, they are not rich. We must protect the panda, some panda has been found, there are some pandas still suffer from the endless pain. We want to be treated, if they are they, by this pain?

Here, I appeal to everyone: love animals, let animals no longer afraid of us, let the world become real peace!

At the same time I also urge those who hurt the panda: panda also have life, pandas have feelings. Their value is not let us make a living, but live for yourself. I hope you can stop here!

今天下午,我打开电脑上了qq,,在qq空间里看见了“惊天地泣鬼神”的一幕。

一些人准备取小熊的胆汁,这时,一只母熊挣脱了铁笼,用巨大的熊掌掐死了小熊,然后把头撞上墙壁,死了。也许这是它们最好它们的办法,因为它们解脱了。

看完这一则故事,我快哭了。这么可爱的小熊,这么伟大的母熊,是谁狠心夺走了它们的生命?是人类。口口声声说保护大熊猫的是谁?也是人类。这不是自相矛盾吗?大熊猫是我国的国宝,可一些熊猫看见人类就想逃。这是为什么?因为有人伤害熊猫。

熊猫是多么可爱啊!他们也有生命,它们不是致富的工具。我们一定要保护熊猫,一些熊猫已找到,还有一些熊猫还在受那无尽的痛苦折磨。我们要将心比心,假如自己是它们,受到这种痛苦会怎么样?

在这里,我呼吁大家:爱护动物,让动物不再惧怕我们,让这个世界变得真正和平吧!

同时我也奉劝那些伤害熊猫的人:熊猫也有生命,熊猫也有感情。它们的价值并不是让我们赚钱,而是为自己而活。希望你们能到此收手!

A thought-provoking dialogue between the mother elephant and her own child appears in the first picture. Having growing his teeth, the young elephant is eager to share the exciting news with his mother. However, after repeating his words several times, there is still no response coming from the mother. Meanwhile, the attractive caption in the second photo reads: no trade, no kill.

The above pictures unveil a hazard posed to wildlife due to the expanding scale of world commercial hunting. At least two fundamental factors could contribute to this phenomenon. The industry of commercial hunting have undergone a booming expansion (along with the growing public awareness of the merits of wildlife, which makes/), making hunting unusually profitable. Worse still, lacking knowledge regarding the significance of ecological balance, some people take the gun to chase animals insatiably (and thus cause a severe threat to all life in the world). Apparently, this trend will surely in turn endanger humankind in the long run.

(On no account should we turn a blind eye to such things.//All these factors above make it crucial to take drastic measures to protect the wildlife.) Accordingly, governments all over the world are supposed to unite to work out effective measures against commercial hunting. Additionally, people should be educated from childhood to cultivate the awareness that we and the rare wild animals share the same precious planet. I do believe a harmonious relationship between the wildlife and human beings is awaiting us if we make every effort to promote wildlife protection both nationally and internationally.

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。

giant panda for many years. As a result, he found that it was human being that

made these lovely animals die out. At that time, many people believed that giant

panda became less because of the low rate of newborn babies. But it was not

true. People cut trees for making profit at that time. Panda lose homeland and

they lacked of food. Thanks to these valuable data, the government took the

篇19: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。
