​导语: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。下面是yuwenmi小编为大家整理的优秀英语作文,欢迎阅读与借鉴,谢谢!

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 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.

【参考译文】

动物需要人类的保护

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。

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。

Mistreat your animals and someone might take them from you.

Allen (not his real name) is driving north out of Virginia in the middle of the night, with stolen property in the back of his van. But Allen isn‘t a criminal – in fact he normally would never dream of breaking the law.

The “property” he stole is a dog he calls Flash. Allen doesn‘t particularly want Flash – in fact, in a few hours he‘ll drop him off at a stranger‘s house and never see him again. “I couldn‘t just stand by and do nothing,” he explains. “The owner was plainly neglecting the dog, but the police wouldn‘t do anything about it.”

For over a year, Flash had been tied to a tree in front of someone‘s house. “He was sick and malnourished,” says Allen. “More than once I saw [the owner] kick him for no reason at all.” Allen had repeatedly tried to get the owner to take better care of the animal, or to give it away to someone who would. Finally, he took matters into his own hands – in the dead of night, he took Flash off his chain and drove away with him.

Within an hour, Flash had a new license tag and was being treated by a veterinarian who knew better than to ask questions. Pictures of the dog were put up on animal rescue websites, asking for someone to adopt the dog. A couple in New York offered to take the dog, and animal lovers in states along the way agreed to provide transportation.

Nobody can say for sure how many animals like Flash are ‘rescued‘ every year – receiving stolen property is a crime, so rescuers tend to stay in the shadows. But a growing number of empty collars attests to their work as more and more animals find their way to loving homes.

Animals are friends of human beings. An animal is dependent on the human, also, the human also cannot leave the animals.

Long, long ago, animals and humans are a good friend. They help each other, rely on each other, get along with, who also cannot leave the who. However, with the passage of time, because of human beings, the animals with human relations soured, and there are more and more serious trend.

First of all, human beings to animals is wanton killing, on the one hand, caused a substantial reduction in animals, on the other hand also caused the animals to human hostile, to some extent destroy the animals with human friendly relationship. In fact, for a long time, the behavior of the human animal cruelty has not rested, eat eat peacock, owls, monkey, red-crowned cranes, bear bile absorption, is really to the point of "all things" entrance! What do you want to, so can not cause animal angry? How can you make animals not to stand up and fought back? This is also the animal attack humans, even damage the important reason of human life.

Second, with the progress of human society, some bad behaviors of human beings, not only destroyed the earths environment, and damage to the animals living environment. Factory sewage, automobile exhaust, deforestation of forests and other bad behavior, have caused serious damage to nature, and at the same time there are opposite to the nature of the direct damage caused by animals that makes the animal difficult to live, the type and quantity less and less, destroy the balance of the ecosystem, eventually make human to destruction.

Visible, the relationship between animals and humans have come to the point where serious deterioration, at the same time, also pose a threat to the survival of mankind itself. Humans are still can such wrong-headed, impenitence? ! I think that human beings should be timely change their bad habits, to love animals, protect earths environment.

As a primary school student, we should start from me, start from now, to take care of our nature, protect the animals around us.

Let us act together, take care of animals, people for the ethical treatment of animals, and become a good friend of animals, to improve the relationship between the animals and humans to make their due contribution!

动物是人类的朋友。动物离不开人类,同样,人类也离不开动物。

很久很久以前,动物和人类是一对好朋友。他们互相帮助、互相依靠、和睦相处,谁也离不开谁。但是,随着时间的推移,由于人类自身的原因,造成了动物与人类的关系恶化,而且有越来越严重的趋势。

首先,人类对动物的肆意捕杀,一方面造成了动物的大量减少,另一方面也造成了动物对人类的敌意不断增强,一定程度上破坏了动物与人类的友好关系。事实上,一直以来,人类残害动物的行为一直没有停息过,吃孔雀、吃猫头鹰、吃猴脑、吃丹顶鹤、吸熊胆,真是到了“万物皆入口”的地步!您想,这样怎么能不引起动物的愤怒呢?怎么能让动物不挺身而出、奋起反击呢?这也是造成了动物攻击人类、甚至伤害人类生命的重要原因。

其次,随着人类社会的不断进步,人类自身的一些不良行为,不仅破坏了地球环境,也破坏到了动物的生存环境。工厂的污水、汽车的尾气、对森林的过度砍伐等不良行为,都对大自然造成了严重的破坏,同时也对生存在大自然的动物造成了直接的伤害,使动物生存艰难,种类、数量越来越少,破坏了整个生态系统的平衡,最终使人类走向灭亡。

可见,动物与人类的关系已经到了严重恶化的地步,同时,也威胁到了人类自身的生存。人类难道还能这样执迷不悟、不知悔改吗?!我想,人类应该及时改变自身的不良习惯,爱护动物,保护地球环境。

作为一名小学生,我们应该从我做起,从现在做起,爱护我们的大自然,保护我们周围的动物。

让我们大家一起行动起来,爱护动物,善待动物,成为动物的好朋友,为改善动物与人类的关系做出自己应有的贡献吧!

动物是我们人类的好朋友,我们不能伤害它们,但有些人却为了自已的利益,不顾那些可怜的小动物的生命,去践踏它们,捕杀它们。

记得那是今年暑假的一天,我和姥姥在公路的一边坐着聊天,我看见一只小猫想穿过马路去吃对面的一块肉,谁知,小猫刚走到马路中间,一辆大卡车过来了,司机先生一边按喇叭,一边嘴里骂道:“死猫走开。”小猫还没理解了司机的意思,司机先生已不耐烦了,他一踩油门,一个小生命就这样死在了满载货物的大卡车的车轮下。我看着这一幕又气愤又伤心,为了纪念这只可怜的小猫,所以我想把这一天——7月2日设立为保护动物节。

到了每年的这一天,人们都要为保护动物做贡献,要让小动物轻松愉快地度过这一天,不能让它们受到伤害,小动物不管到了谁家,人们都要热情招待它们,最后,我们还要用各种不同的方式去宣传小动物对人类的帮助。让世界上的每一个人都要保护小动物。

篇14: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。
