不要再破壞自然界中的一草一木，不要再亂殺一禽一獸，不要再殺害我們的朋友，要保護(hù)好自然界中的一個(gè)個(gè)生靈。消滅動(dòng)物，就是在消滅人類自己。請(qǐng)保護(hù)動(dòng)物!學(xué)習(xí)啦小編整理了關(guān)于冬天的動(dòng)物的英語(yǔ)美文，歡迎閱讀!
關(guān)于冬天的動(dòng)物的英語(yǔ)美文篇一
Hibernation
Hibernation is more than sleep. It is a very deep sleep. The animal's temperature drops to just over zero centigrade, and its heart beats very slowly. People who find hibernating animals asleep often think that they are dead: the body feels very cold, and the creature may breathe only once every five minutes. A hibernating animal cannot feel any pain. You can touch it, or even pull its tail, without causing it to move or wake up. In its hibernating state it can even live in a poisonous atmosphere for a long time without any ill effect.
Hibernating in this way, the animal can sleep all through the winter. You might wonder how it manages to live without eating for so many months. The answer lies in two facts. The first is that it has stored supplies of fat in its body during the summer and autumn. The second is connected with the main use the body makes or rood——to supply the energy for movement. We have seen that hibernating animal reduces movement to far below the ordinary level. Even the movements or the heart and lungs are greatly reduced. The animal hardly makes any movement, hardly use any energy, and hardly needs any rood.
Some animals, including some bears only hair hibernate. That is to say, they sleep during the winter, but their sleep is not deep and their body temperature does not drop, as they are warm blooded animals. In the antumn the bear eats and eats and becomes very rat. His hair grows longer. Soon he has a thick covering or rat and fur. In November he rinds a place to lie down and goes to sleep. On warm winter days he may think spring has arrived;he gets up and wa[ks around. When he sees that the snow is still thick on the ground, he quickly goes to sleep again.
冬眠不僅僅是睡眠，而是一種沉睡。動(dòng)物的體溫降到剛好在零攝氏度以上，心臟跳動(dòng)非常緩慢。人們看到處于冬眠狀態(tài)的動(dòng)物，常常以為它們是死的：身體摸上去冰涼，可能每5分鐘才呼吸一次。冬眠的動(dòng)物感覺(jué)不到任何疼痛。你可以摸它，拉它的尾巴，也不能使它動(dòng)一動(dòng)或醒過(guò)來(lái)。當(dāng)它處于冬眠狀態(tài)時(shí)，甚至可以長(zhǎng)時(shí)間地生活在有毒空氣中而無(wú)任何不良后果。
用這樣的方式越冬，動(dòng)物可以睡過(guò)整個(gè)冬天。你或許會(huì)覺(jué)得奇怪，它好幾個(gè)月不吃東西，怎么活過(guò)來(lái)的呢?可以從兩方面的事實(shí)中得到答案。第一，在夏秋季節(jié)，動(dòng)物體內(nèi)儲(chǔ)存大量的脂肪。第一是與食物對(duì)身體的主要用途，即食物供給身體活動(dòng)所需的能量有關(guān)。我們已經(jīng)知道，冬眠的動(dòng)物把活動(dòng)量減少到大大低于一般的水平。甚至心肺的活動(dòng)量也大大減少了。冬眠的動(dòng)物幾乎沒(méi)有什么活動(dòng)，幾乎也不消耗什么能量。因此它也幾乎不需要什么食物。
有些動(dòng)物，包括有些熊，只是半冬眠。就是說(shuō)，每到冬天它就睡覺(jué)，不過(guò)他們睡得不那么沉，因?yàn)樗麄儗贉匮\(yùn)動(dòng)，所以體溫不下降。在秋天，熊吃了又吃長(zhǎng)得真是肥極了。它身上的毛也長(zhǎng)得更長(zhǎng)了，很快全身就包滿了一層厚厚的脂肪和毛。到了11月，它找個(gè)地方躺下睡覺(jué)了。在冬天暖和的日子里，它可能以為春天已經(jīng)來(lái)到了，便起來(lái)四處走走，當(dāng)它看到地上積雪仍然很厚時(shí)，它很快又去睡了。

American researchers spent two summers studying polar bears on the Arctic sea ice. They found that sea ice, where polar bears spend much of their lives, is melting faster than experts predicted it would. The researchers say this change in the animals' home territory is threatening their survival.
美國(guó)科研人員用了兩個(gè)夏天研究生活在北極海冰上的北極熊。他們發(fā)現(xiàn)，海冰正在快速地融化，比專家預(yù)測(cè)的還要快，而北極熊一生中的大部分時(shí)間都是在海冰上度過(guò)的?？蒲腥藛T說(shuō)，發(fā)生在北極熊家園領(lǐng)域內(nèi)的變化正在威脅著它們的生存。
The scientists published a report on their study in the journal Science. The report says polar bears face a difficult future unless countries reduce air pollution.
這些科學(xué)家在《科學(xué)》雜志上發(fā)表了一篇跟他們的研究相關(guān)的報(bào)告，該報(bào)告聲稱，除非各個(gè)國(guó)家減少空氣污染，否則北極熊的未來(lái)會(huì)非常嚴(yán)峻。
Polar bears live on the ice. It is where they hunt, mate and raise their young. But a team of researchers has found that the animals' ice habitat is warming up, and shrinking.
北極熊生活在海冰上。他們獵食、交配、生兒育女，處處離不開(kāi)海冰。但是，一個(gè)科研團(tuán)隊(duì)已經(jīng)發(fā)現(xiàn)，北極熊的海冰棲息地正在變暖和萎縮。
The team was from the University of Wyoming. Its members worked in the Arctic between 2008 and 2010. Merav Ben David was among the researchers. She says they learned that polar bears often have trouble finding food. She says the lack of food can affect their mental health.
這個(gè)科研團(tuán)隊(duì)來(lái)自懷俄明大學(xué)，團(tuán)隊(duì)成員在2008年到2010年之間對(duì)北極進(jìn)行了研究。梅-本-傣威是成員之一。她說(shuō)他們發(fā)現(xiàn)了北極熊常常在尋找食物上陷入困境，而缺乏食物會(huì)影響他們的心理健康。
"So if shortening of the spring hunting season, lengthening of the summer season where they are food-deprived and still experiencing difficulties in getting food in the winter, polar bears are stressed physiologically."
“因此，如果用于獵食的春季正在變短，而食物短缺的夏季正在變得漫長(zhǎng)，冬季尋找食物又面臨困難，北極熊的身體就會(huì)無(wú)法忍受。
Ms. Ben David says if the animals do not eat enough food in the spring, they are in poor health when winter arrives.
本-傣威女士說(shuō)，如果這種動(dòng)物春季進(jìn)食不夠充足，當(dāng)冬天到來(lái)時(shí)，它們就會(huì)處在不健康的狀態(tài)中。
The researchers traveled on helicopters and ships. They captured more than 20 polar bears, and tested their blood. Before releasing the animals, the researchers equipped them with devices to measure temperature. They then followed the movement of the polar bears on ice and on land.
科研人員的科研之旅是在直升機(jī)和輪船上度過(guò)的。他們捕捉了二十多頭北極熊，檢測(cè)了它們的血液。在它們身上安裝了測(cè)量溫度的設(shè)備后，他們釋放了這些動(dòng)物。接下來(lái)，他們對(duì)北極熊在海冰上和陸地上的行動(dòng)軌跡進(jìn)行了跟蹤考察。
Other studies had suggested that the bears could deal with a lack of food in the summer by reducing their activity -- like the animals do when they hibernate in the winter. But Ms. Ben David says the researchers discovered that did not happen.
曾經(jīng)有其他研究認(rèn)為，通過(guò)減少活動(dòng)，北極熊能夠應(yīng)對(duì)夏季食物的匱乏——就如同冬季冬眠一樣。但是，本-傣威女士說(shuō)，這種情況不會(huì)出現(xiàn)。
"We found that polar bears -- like their nearest relatives the brown bears -- are incapable of reducing their metabolic rate to the level that we see during winter hibernation. So there are limits on how long they can go without feeding in the summer."
“我們發(fā)現(xiàn)，類似于它們最近的近親棕熊一樣，北極熊是無(wú)法把它們的代謝率降低到我們所知的冬季冬眠時(shí)的標(biāo)準(zhǔn)的。所以，夏季沒(méi)有食物，會(huì)影響北極熊到底能走多遠(yuǎn)。
Ms. Ben David says 20,000 to 25,000 polar bears live in the Arctic. She says the world should take action to protect them.
本-傣威女士疾呼，現(xiàn)在的北極，只有兩萬(wàn)到兩萬(wàn)五千頭北極熊，為了保護(hù)它們，全世界都應(yīng)展開(kāi)行動(dòng)。
"If we want to be responsible citizens of this planet, we have to do everything in our power to stop, reverse the trend of sea ice loss."
“如果我們想成為這個(gè)星球上勇于擔(dān)責(zé)的公民，我們必須采取一切措施阻止、改變海冰減少的趨勢(shì)。
She says countries must work to limit the greenhouse gases that studies have linked to rising temperatures. She says if that does not happen, polar bears could one day disappear from our planet.
她說(shuō)，所有國(guó)家都必須投入到限制溫室氣體排放的工作中來(lái)，因?yàn)闇厥覛怏w會(huì)引起氣候變暖，如果不這樣做，北極熊遲早會(huì)從地球上消失。

它也是一個(gè)“小饞嘴”雖然它的食盆里永遠(yuǎn)沒(méi)空過(guò)，可每次我拿生菜葉子喂它時(shí)，它總是頭也不抬一下的狂吃，不到兩分鐘美麗的生菜葉子立刻變成一把“破扇子”。
看!我的小鸚鵡可愛(ài)吧!
