動物英語作文 篇1

The snake is a long and thin animal that lives in grass or other dark places. 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.

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.

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 snake's body. After some time the lump disappears.

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.

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.

動物英語作文 篇3

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.

北冰洋在秋季結冰以後，北極熊就會出發去尋求它們最喜歡的食物：富含脂肪的海豹和鬍子海豹。海冰在夏季開始融化斷裂。這使北極熊在夏季無法吃到美味的海豹，所以它們進入禁食期。至少，情況應該是這樣。但是由於地球變暖，温暖的無冰季節越來越長。那飢餓的北極熊要怎麼辦?

科學家曾經認為，北極熊可能會轉向陸地上的食物來補充它們對鰭足類動物飲食的需求，進而生存下去，這些陸地食物包括雪雁、雪雁蛋和北美馴鹿。

“文獻中有過這類辯論，即在寒冷融化時陸地食物是否能滿足北極熊的營養需求。”

尼克·皮爾福德是加拿大阿爾伯塔大學的生物學家。

“通過上世紀70年代初的'研究，還有早期的探險者日誌，我們很早以前就知道，北極熊會以陸地食物為食。但是辯論的焦點在於，這些食物是否能增加北極熊的能量。”換句話説，這些替代食物能否為北極熊提供足夠的營養，彌補不能進食海豹帶來的損失?

為了解開這個疑惑，皮爾福德及同事對西哈德遜灣荒野地區的北極熊在無冰季期間每天失掉的體重進行了估算，從表面上看，北極熊在這段時間食用了陸地食物。隨後，他們將這一數據與通過馬尼托巴北極熊預警計劃暫時捕得的北極熊所失掉的體重進行了對比。

在被關期間，北極熊不吃東西。它們的體重每天大約下降1公斤。雖然野生北極熊能享用北極“小吃”，但是它們的體重每天也同樣會下降1公斤。這一研究結果發表在《生理學和生化動物學》期刊上。

“顯然結果表明，陸地食物不能為北極熊提供足以抵消大量損失的能量。所以，北極熊可以從食用海冰下面的食物轉向食用陸地食物，並幫助它們對抗日益延長的無冰季這個觀點，並沒有在這項數據中得到證明。”

問題是，北極熊進化成了依靠海洋食物的動物。

“陸地食物以蛋白質和碳水化合物為基礎，而北極熊需要的食物以脂肪為主。脂肪是這些熊真正需要的東西;它們高度適應的情況是，將脂肪吸收進它們的系統中，然後把這些脂肪放在身上以增加體重，這樣它們之後就可以依靠這些脂肪來度過禁食期。唯一能提供給北極熊這種脂肪的就是海洋哺乳動物。但是它們只能在有海冰時食用到這些海洋哺乳動物。”

成年北極熊可以8個月不進食。但是小一些的未成年北極熊已經不再被哺育，它們必須要去獵食，可是它們不能在漫長的無冰季期間一直不進食。所以，隨着北極地區變暖，較小的北極熊將會大批死亡。這使這些物種的生存成為問題。

動物英語作文 篇4

I like dogs, because they are man’s good friends. They can do many helpful things to us, such as guarding our houses, greeting guests, helping the police, and so on.

Some trained dogs can even lead the blind people and save people’s lives.

So they‘re treated as our family members. I hope someday dogs will be in great harmony with human-beings.

動物英語作文 篇5

The animal is the friend of our human beings. We live in the same earth. Animals and human beings can’t be separated from each other.

But some animals are getting less and less. So it’s necessary for us to protect animals, especially wild animals. Some people kill wild animal because of money.

It’s illegal. Beside, because of the development of society, human needs more space to live in, so we explore the forest. Animals have less space to live in. The number of wild animals decreases year by year.

It’s high time to take actions to protect wild animals.

動物是人類的朋友,我們共同生活在地球上.動物和人類不能彼此分離.但有些動物的數量越來越少,所以我們有必要去保護動物,特別是野生動物.一小部分人為了賺錢而去獵殺野生動物,這是違法行為.

此外,由於社會的發展,人類需要更多的生活空間,所以要開發森林.然而動物的'生存空間卻變少了.

野生動物的數量逐年減少,現在該是採取措施保護野生動物的時候了.

動物英語作文 篇6

I have a pet. It is a pigeon. It has got white and gray feathers, a red mouth and two small eyes. It’s cute.

I found it near a park. Its leg was injured and couldn’t fly. I took it home and cured it. Every morning, I give it some water and small pieces of bread. It gets stronger and stronger.

Now the pigeon has become my best friend. When I come home from school, it always flies to me and rests on my shoulders, it likes to talk to me. It makes my spare time colorful.
