动物的英语作文 篇1
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, that's what's supposed to happen. As the planet warms, the warmer ice-free season is getting longer and longer. So what's 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.
"We've 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 we've 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 Manitoba's 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 that's going to help supplement against longer ice-free seasons, that really doesn't 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; they're 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 that's going to provide them with that type of fat are marine mammals. And they can only access those marine mammals when there's sea ice."
Adult males can go eight months without food. But younger, sub-adult bears, which are no longer nursing and must hunt, can't 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。

Dolphin is my favourite animal.
It is one of the most precious animals. Their bodies are very long, about one zhang（丈）. Dolphins live in the sea. They live on fish, shrimps and so on.
Dolphins are very friendly and peaceful. They never attack people. Instead, they have saved many people in danger in the past years. How helpful the dolphins are!
Dolphins are very clever. People often train them so that they can give a dolphin show which brings people a lot of happiness and joy.
Unluckily, the number of dolphins is getting smaller and smaller. Because of water pollution, there is less and less space for dolphins. Many people make money by hunting dolphins. If we don’t protect them, maybe we’ll lose our good friends one day. As a student, I hope more and more people should take actions to protect dolphins.

动物的英语作文 篇4
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 20xx, 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.
很多动物频临灭绝的危险。图表显示，我们可以看到动物物种数量下降的速度越来越快，而且这种趋势将会持续下去。从1980年到20xx年，至少有100万动物物种已经消失。更糟糕的是，越来越多的野生动物处于巨大的危险中。这不是一则耸人听闻的新闻，这是一个事实，一个残酷的事实。不幸的是，将来我们可能看不到这些动物了。
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.
从第二幅图我们可以找到一些原因。为什么动物物种的数量一年年的减少呢?显然，动物成为了时尚工业的受害者。动物的皮被用来做时髦的衣服，而且这些衣服都是高价出售。因此，一些贪婪的人就开始大量屠杀动物。这种不负责任的行为不仅打破了自然的`平衡，而且使人类居住环境陷入危险。
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 people's awareness to protect animals and our environment. In this way, we can build a harmonious society and ensure a sustainable development.
在我看来，我们必须要做些什么来阻止这种违法行为。我相信“没有买，就没有杀”。首先，我们必须制定有关法律来保护这些处于危险中的动物。其次，我们必须采取一些措施有效的保护动物。动物是人类的朋友，也是我们环境的一部分。再次，我们应该提高人们保护动物和环境的意识。这样一来，我们就可以建立一个和谐的社会，确保其可持续发展。

By doing this we may be given deeper impression on the great power of the nature. To know how precious the animals are , and how to love them and live with them to keep the balance in the nature.

动物的英语作文 篇7
there is only so much land on the earth, and so what we can do with it is limited. some people believe that human needs for farmland, housing and industry should come first, while others believe that some land should be set aside for endangered animals. i am of the opinion that we should reserve some land for the worlds animals for the following reasons.
first, mankinds need for land is constantly growing. if the demand is not checked in some way, humans will eventually develop all of the earths available land. at that time, mankind will have no more room to grow, and all the wild animals will have disappeared, as well as other valuable resources. second, humans are able to innovate and can use the land that they already possess in more efficient ways. animals are unable to do this. once their land is taken away from them they will die. third and last, endangered animals are an important part of the biodiversity of our planet. if they disappear, we cannot predict what the effect will be. therefore, we should treat such animals as a valuable resource to be protected.
to sum up, the worlds endangered animals are an important resource and we should protect them by setting aside some land for them. although mankinds need for land continues to grow, people are intelligent and inventive enough to put the land they have to better use. in this way, we can have enough land for farming, housing and industry, and preserve the biodiversity of the planet at the same time.
译文
地球上的土地就只有这么多，所以我们可以利用土地的方式有限。有些人认为人类对于耕地、居住以及工业的需求应该摆在第一位，但是有人则认为，有些土地应该留给濒临绝种的动物。我的看法是，基于下列的理由，我们应该保留一些土地给地球上的动物。
首先，人类对土地的需求在不断增加。如果这些需求不以某种方式来加以抑制，人类最后将会开发完地球上所有可用的土地。到那时候，人类将没有栽种作物的`空间，而且全部的野生动物将会和其他宝贵的资源一样消失殆尽。其次，人类可以创新并且以更有效率的方式来使用已经拥有的土地，动物则无法做到这一点。一旦土地被剥夺，它们就会死亡。第三点，也是最后一点，濒临绝种的动物是我们地球上物种多元性的重要组成部分。如果它们消失了，我们无法预测将会造成什么样有影响。因此，我们应该把这些动物视为需要保护的珍贵资源。
总之，全世界濒临绝种的动物都是一项重要的资源，我们应该加以保护，并且保留一些土地给它们。虽然人类对于土地的需求在持续增加，但人类很聪明，而且具有创造力，能够更充分利用所拥有的土地。如此一来，我们会有足够的土地耕种、居住，并用来发展工业，而且能同时保持地球物种的多元性。
