Snakes蛇

The snake is a long and thin animal that lives in grass or other dark places. A snake has no legs or feet, but it can move very fast on its stomach. Snakes usually have green, yellow or black skins, which make them difficult for their enemies to find them.Some kinds of snakes live in water. They can swim as freely as fish.

蛇是一种又长又瘦的动物,生活在草丛里和阴暗的地方、蛇没有腿和脚,靠胃部飞快的移动前进。 蛇常常有绿色,黄色和黑色的皮肤,使得敌人很难找到他们。

Snakes are cold-blooded animals. In winter they hibernatein holes which are narrow enough only to hold the snakes bodies. The snakes can sleep through a whole winter without eating and moving. They can not feel any pain. The hibernation period lasts about five months. When spring comes, the snakes come out and begin their normal life.

蛇是冷血动物,在冬天,它们通常隐藏在只能容下它们身体的狭小的小洞里。蛇可以不吃东西,不移动地睡一整个冬天。它们不会感觉到痛苦,它们的隐藏时期持续大概5个月。当春天来临的时候,蛇就会出现并开始它们的正常活动。

Snakes can take many things as food, such as mice, sparrows, frogs,birds eggs, pests and so on. People sometimes can see a snake eat a sparrow. First it moves close to the sparrow, then it puts out its tongue and brings the sparrow into its mouth and swallows it, which makes a lump in the snakes body. After some time the lump disappears.

许多东西都可以成为蛇的食物,就像老鼠,麻雀,青蛙,鸟蛋和害虫等等。人们常常看见蛇吃麻雀,蛇首先靠近麻雀,然后伸出它的舌头把麻雀带进它的嘴巴里并吞下去。麻雀就像一块肿瘤一样突出在蛇的身体里,但是过了一段时间就会被消化消失。

As snakes are dreadful-looking, people are afraid of them. Many people drive them away whenever they see snakes. But in Chinese fairy tales, snakes are by no means bad. They seem to have human feelings. They can change into pretty girls. People like and respect them. The most well-known is the story about the White Snake and the Blue Snake.

因为蛇看起来很可怕,所以人们总是害怕它们,很多人每当看到蛇的时候都会把它们赶走。但是,在中国的神话故事里,蛇并不代表坏人,它们可以感觉到人类的想法,它们会变成美丽的女生,人们喜欢和尊重它们。最著名的故事就是白蛇与青蛇的故事了。

In fact, snakes are not as dreadful as they look. They can help us to kill mice and pests. They can provide us with delicious meat. Their blood is a good drink. Poisonous snakes are especially useful. We can make valuable drugs with them.

事实上,蛇并不是像它的样子那么可怕,它们可以帮助我们杀死老鼠和害虫,它们可以给我们做成美味的佳肴,它们的血是很好的饮料。毒蛇就特别有用处了,我们可用它们做成珍贵的药品。

Orcas are not related to whales at all, other than being ocean-dwelling mammals. Rather, they are close kin to dolphins. While it was believed that they were a single species, recent research indicates that they may, in fact, be comprised of several different species of Orca. You can find them in every ocean in the world, though they tend to favor the colder waters around Antarctica and the North Atlantic or Pacific. The only predator they possess is humankind. While theres a deadly standoff between the two species, Orcas proliferate in the wild, and have an incredible life span. The males usually live as long as sixty or seventy years, while the females—who are excluded from the sometimes-violent competition for mates—may live a hundred years or more in the wild.

虽名虎鲸,但不同于海洋其他哺乳动物,非鲸目,海豚科的近亲。此前一直认为虎鲸只有一种,但最近的调查显示虎鲸种类繁多。部分虎鲸会终年停留于南极、大西洋北部和太平洋等温度较低的海域,但总体来看,它们的活动范围几乎覆盖全世界水域。它们堪称海上霸王,唯一的天敌也只有人类了。虎鲸全年都可以交配,数量庞大,雄鲸的平均寿命在60到70年左右,野生雌鲸不同于雄鲸经常参与猎杀食物,寿命可达100年甚至更长。

Theyve been observed reaching speeds of around 30 miles per hour, although some Orcas may utilize much greater bursts of speed, based upon their favored prey. Resident pods in the Pacific Northwest have shown a decided preference for salmonids—specifically, Chinook salmon. This presents a conflict with the goals of companies that rely on high yields of salmon for profit. Several communities of killer whale seem to favor beach and ice floe ambush approaches, snatching seals and walruses or even sea birds from their resting places. Others, located in the Southern Hemisphere, take up the challenge of hunting sharks in the open sea, as well as feeding on species of rays and other fish abundant in the cold southern waters.

虎鲸约时速30英里,当然也有爆发力更强的,为了追捕中意的猎物,时速可以更快。太平洋西北海域的虎鲸族群偏爱三文鱼,尤其是大鳞三文鱼。这就和沿岸经营三文鱼生意的公司产生一定的利益冲突。虎鲸族群喜欢在浮冰区伏击猎物,捕杀海豹、海象或者在这里歇脚的海鸟。在南半球海域里,有些虎鲸还会在公海里捕杀鲨鱼,也会以鳐和其他鱼类为食。

呼吁保护动物英语作文3

Animals Need Protecting

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 alone are considered in danger.

Why should people careBecause 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. WhyBecause 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 plant on the danger list. Slowly, the number of some animals in danger is growing.

Nowadays, with the improvement of the people’s living standard, some people form a habit of raising small or domestic animals as pets. Some raise small dogs or cats as their pets while others raise various birds or fishes as their pets. There are still even some people raising snakes and other unusual animals as their pets.

Does anyone have the same opinion of raising animals as pets? No, some people object to the idea of raising animals as pets. To them, animals have their own right to live a natural life like human beings. On the other hand, the way people raise animals as pets have a negative influence on the surroundings such as dogs’ barking at midnight, dogs’ chasing people on the street and so on. What’s more, some animals will transmit some diseases.

In my opinion, I do not like the idea to raise animals at pets. Animals have their own right to lead a life as they like. We should not deprive them of their natural right. In this way, we will live in a peaceful world in harmony with the other living creatures.

如今,随着人们生活水平的提高,有些人养成了饲养小动物或家畜作为宠物的习惯。一些养小狗或猫作为他们的宠物,而其他人饲养各种鸟类或鱼类作为他们的宠物。甚至还有一些人饲养蛇和其他不寻常的动物作为他们的宠物。

任何人都有相同的意见,饲养动物作为宠物吗?不,有些人反对将动物作为宠物饲养。对他们,动物有他们自己的权利,生活像人类一样自然。另一方面,人们饲养动物作为宠物的方式对环境有负面影响,如狗的叫声在半夜,狗追逐人在街上等。更甚的是,有些动物会传播某些疾病。

在我看来,我不喜欢养宠物。动物有他们自己的权利,过他们喜欢的生活。我们不应该剥夺他们的自然权利。这样,我们将生活在一个和平的世界中,与其他生物和谐相处。

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。
