动物英语作文 篇1
It was fine yesterday, I went to Beijing Zoo with Wang Fei. There were lots of animals in the zoo. We saw elephants, monkeys, bears and so on. They were so interesting. But we saw some visitors throwing stones to a small monkey. We went over to them and stopped them. We said to them,"Don't throw anyting to animals. It is our duty to protect animals." They said they were sorry after hearing our words. Later we were tired and we went back home. We enjoyed ourselves in the zoo yesterday.

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。
动物英语作文 篇3
human is the creature which is the closest to god. it means we have more duties and rights for this world. biological diversity have been damaged by the developing of modern society, which have threatened to the life of animals as well as the life of human. the etinction of animal is an alarm to human beings.
with the process of human civilization, our life become more and more comfortable and convenience, it may be a good news to man but a bad news to animals. ehaust gases are emitted to the atmosphere, which react with each other and combine with water vapor ,and finally lead to form acid rain. acid rain fall into lake and kill the frogs and the fishes. time will tell you, although the recent acid rain may not directly harm to us, we would not escape from the doom if we ignore the alarm from animals. we are a part of the food chain. most of the human’s diets come from animals, which means the dangers that are threatened not only the animals but also the human. several serious diseases from animals have brought us into the hell in the beginning of the new century. for eample sars, the horrible disease has killed thousands of people which was attributed to eating the ill wild animals.
as the end of the food chain, we should spend money on preventing wild animals which is a confession from the evil consequence. i believe no one would neglect the alarm from animals if he recognized it, no one would be of parsimony with the money if it is used in preventing himself. development of society and preventing animals are our right and duty which also need us to balance.
动物英语作文 篇4
I have a puppy, and I love it very much. Its black eyes are like two black gems, and its fur is like a blanket, and its four legs are like four furry little pillars, and its tail is shaking and it seems to be waving to you.
Because I called the jingle, so my mother wanted to give it a small buzz, but I do not agree, I give it a little name, because I think it is good every day.
It is very naughty, when we go out to eat, it is always guilty of trouble, trouble, it jumped on the sofa mess, but also the newspaper, napkin tear all over the floor are. When I came back, I saw the ground mess, I was angry, and ignore it. It is also aware of their mistakes, and rushed to my knees, as if to shed tears, said: "Master, forgive me!" I see it so poor, forgive it.
My dog is really cute and naughty ah!
动物英语作文 篇5
In the past, there have been many endangered animals. Now they are extinct. Does it matterHas our environment been affected by their absenceHas the quality of our own life been changedThe answer to these questions is “Yes.”
It does matter if we destroy an endangered species habitat to develop more farmland, housing or industrial parks.It will effect all the other creature.
For example, if certain trees are cut down, birds and bats will have no place to roost.They cannot roost, they cannot breed. If there are no bats or brids, there will be no animal to eat certain insects that plague our crops.
Jungle around the world are being cut down to make room for humans. We will never be able to see or study this fragile ecosystem.
Human beings should be responsible for their own acts of nature. The promulgation of laws to maintain ecological balance, to make more space and natural. Conservation biology, Protect environment, protection of natural.
在过去，有许多濒临灭绝的动物。现在他们绝种。这很重要吗？我们的环境
是受他们的缺席的影响？我们生活的质量发生了变化？这些问题的答案是“是
的”
更要紧的是如果我们破坏濒危物种的栖息地，以开发更多的农田，住房和工
业园区。它会影响所有其他生物。
例如，如果某些树木被砍伐，鸟类和蝙蝠将无处栖息。他们不能称雄，他们无法繁殖。如果没有了蝙蝠或鸟类，就没有动物吃困扰我们的庄稼的某些昆虫
世界各地的森林被砍伐让路给人。我们将永远无法看到或学习这脆弱的生态系统
人类应该为自己对自然的行为负责。颁布相关法律维护生态平衡，给自然让出更大的空间等。保护生物，保护环境，保护自然。

蛇
A snake is a long and thin animal that lives in grass or other dark places. It has no legs or feet, but can move very fast on its stomach. Snakes usually have green,yellow or black skins, which make it difficult for their enemies to find them.Some kinds of snakes live in water. They can swim as freely as fish.
Snakes are cold-blooded animals. They take many things as food, such as mice, sparrows, frogs, birds'eggs, pests and so on.As snakes are dreadfullooking, people are afraid of them.
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.
