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.

It's not a simple thing to say to kill animals. Because on the earth, there are many kinds of animals, the number is amazing, and some animals have very strong reproductive capacity. So, to get rid of all the animals quickly, we must rely on skills.
There is a kind of higher animal on the earth, called human. It's no exaggeration to say that they are "the king of animal killers". It is no longer a dream to destroy all the animals on the earth as long as we have human beings.
To eliminate animals, we must first kill and eat. This method is simple, but also can eat. If you can kill some rare animal, grilled skin to sell, will earn eighteen thousand, Why not?? In this respect, human being is the first great man. From ancient times to the present, the ambition has not changed, and the tools are becoming more and more advanced. From stones to cannons, from sticks to rifles, the animals were killed and quickly extinct!
In order to eliminate animals, it is necessary to start with science and technology. Take the goods, what is the higher animal, have found that rodents are very fertile, and there are a lot of animal feed to rats, they want to kill the rats. "So early". Therefore, some scientists, taking the banner of "scientific research", take a lot of white mice as experimental victims, and disguise the "body structure of mice is very similar to human beings". Moreover, after mastering science and technology, a lot of rat poison, pesticide and mousetrap have been produced to accelerate the eradication of rodents. Mouse disappears, chain will be seriously affected, other animal cannot survive, humans are clever!
To eliminate animals, we must also start with the environment. Although this method takes a lot of time, the effect is amazing. A prairie or a forest into a desert means the elimination of thousands of animals. Of course, the wise man thought of this. They have cut trees and abused water, which has rapidly increased the area of the earth's desert and also rapidly reduced the species on the earth. Moreover, human beings also use vehicle exhaust to cause acid rain. This acid rain is very effective for eliminating fish, and it can kill other animals and plants by the way.
The task of eradication of animals is a long way to go. Fortunately, there is a clever human being, believing that in the unremitting efforts of human beings, the eradication of animals will eventually become a reality.
See here you may ask: How did the human be eliminated? Isn't human being an animal? Well, you can feel relieved. When human beings have destroyed other animals, the doomsday of human beings is here!
寫(xiě)動(dòng)物的英語(yǔ)作文 篇6
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(jié)冰以后,北極熊就會(huì)出發(fā)去尋求它們最喜歡的食物:富含脂肪的海豹和胡子海豹。海冰在夏季開(kāi)始融化斷裂。這使北極熊在夏季無(wú)法吃到美味的海豹,所以它們進(jìn)入禁食期。至少,情況應(yīng)該是這樣。但是由于地球變暖,溫暖的無(wú)冰季節(jié)越來(lái)越長(zhǎng)。那饑餓的北極熊要怎么辦?
科學(xué)家曾經(jīng)認(rèn)為,北極熊可能會(huì)轉(zhuǎn)向陸地上的食物來(lái)補(bǔ)充它們對(duì)鰭足類(lèi)動(dòng)物飲食的需求,進(jìn)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(xiàn)中有過(guò)這類(lèi)辯論,即在寒冷融化時(shí)陸地食物是否能滿足北極熊的營(yíng)養(yǎng)需求!
尼克·皮爾福德是加拿大阿爾伯塔大學(xué)的生物學(xué)家。
“通過(guò)上世紀(jì)70年代初的研究,還有早期的探險(xiǎn)者日志,我們很早以前就知道,北極熊會(huì)以陸地食物為食。但是辯論的焦點(diǎn)在于,這些食物是否能增加北極熊的能量!睋Q句話說(shuō),這些替代食物能否為北極熊提供足夠的營(yíng)養(yǎng),彌補(bǔ)不能進(jìn)食海豹帶來(lái)的損失?
為了解開(kāi)這個(gè)疑惑,皮爾福德及同事對(duì)西哈德遜灣荒野地區(qū)的北極熊在無(wú)冰季期間每天失掉的體重進(jìn)行了估算,從表面上看,北極熊在這段時(shí)間食用了陸地食物。隨后,他們將這一數(shù)據(jù)與通過(guò)馬尼托巴北極熊預(yù)警計(jì)劃暫時(shí)捕得的北極熊所失掉的體重進(jìn)行了對(duì)比。
在被關(guān)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(huì)下降1公斤。這一研究結(jié)果發(fā)表在《生理學(xué)和生化動(dòng)物學(xué)》期刊上。
“顯然結(jié)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(zhuǎn)向食用陸地食物,并幫助它們對(duì)抗日益延長(zhǎng)的`無(wú)冰季這個(gè)觀點(diǎn),并沒(méi)有在這項(xiàng)數(shù)據(jù)中得到證明!
問(wèn)題是,北極熊進(jìn)化成了依靠海洋食物的動(dòng)物。
“陸地食物以蛋白質(zhì)和碳水化合物為基礎(chǔ),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(yīng)的情況是,將脂肪吸收進(jìn)它們的系統(tǒng)中,然后把這些脂肪放在身上以增加體重,這樣它們之后就可以依靠這些脂肪來(lái)度過(guò)禁食期。唯一能提供給北極熊這種脂肪的就是海洋哺乳動(dòng)物。但是它們只能在有海冰時(shí)食用到這些海洋哺乳動(dòng)物!
成年北極熊可以8個(gè)月不進(jìn)食。但是小一些的未成年北極熊已經(jīng)不再被哺育,它們必須要去獵食,可是它們不能在漫長(zhǎng)的無(wú)冰季期間一直不進(jìn)食。所以,隨著北極地區(qū)變暖,較小的北極熊將會(huì)大批死亡。這使這些物種的生存成為問(wèn)題。
