一、Marmots托福聽(tīng)力原文：

Narrator:Listen to part of a lecture in a biology class.

FEMALE PROFESSOR:For today's discussion,we'll review the case study on how some animals have behaviorally adapted to their environments.Now,you had to read about two animal species:the eastern marmot and the Olympic marmot.

Marmots are rodents...they're large ground squirrels about the size of an average house cat,and they live in a variety of habitats.And even though they spend a significant portion of the year hibernating,according to this case study,marmots are still considered excellent subjects for animal behavioral studies.Why is that?

MALE STUDENT:Well,when they're not hibernating,you can find them in open areas,and they're pretty active during the day,which makes them easy to observe,right? 

FEMALE PROFESSOR:Uh huh.So,first let's discuss the eastern marmots.They reside throughout the eastern region of North America where there's a temperate climate,where the growing season lasts for at least five months of the year...which is when they do all their mating,playing,and eating.

MALE STUDENT:Oh,I see...at first,I wasn't sure what'growing season'meant just from the reading,but now I get it.It's the amount of time it takes for them to grow,right?So,it'd be five months?

FEMALE PROFESSOR:Hm?Ohh,I'm sorry but no,it has nothing to do with that.It's not about the time it takes for eastern marmots to grow,it's when the food is available.That is--when it's not covered in snow and there's no frost covering the grass,and um vegetative parts of uh,plants,herbs,and the flowers that marmots like to eat. So,'growing season'refers to the availability of the food they eat.Ok?So now,how would you describe the eastern marmots'social habits?

FEMALE STUDENT:Well,they're really territorial and loners and just so aggressive even with other eastern marmots.And their mating ritual is just so...impersonal.

FEMALE PROFESSOR:Uh huh.Now,when they emerge in the spring from hibernation,the mating process begins.For them,well,they come together to mate and then they go their separate ways.Then,about six to eight weeks after birth,the offspring leave their mothers.

FEMALE STUDENT:Really,just six weeks?Is it possible for the offspring to make it on their own so young? 

FEMALE PROFESSOR:Well,it's not as if they aren't ready for the real world...because they are. Remember,they mature quickly and the weather's nice.Also,they live in open fields where there's lots of edible vegetation.So roughly six weeks after birth,eastern marmots are just old enough to take their chances of surviving in a temperate environment. So,how does this relate to their behavior?

FEMALE STUDENT:Oh,I get it.Since,the climate's not too bad,the eastern marmots don't have to rely on each other too much and they really don't need to stay together as a family to survive either.

FEMALE PROFESSOR:Uh huh.And in contrast...the Olympic marmots...what about them?

FEMALE STUDENT:Well,they live together as a family and take care of their young until they're at least two years old.They're really friendly with each other,and what I really like is that they even have greeting ceremonies and they're not at all aggressive and territorial like the eastern marmots. So,um,their social behavior's so different from the eastern marmots'because of the climate where they live?That seems so bizarre!

FEMALE PROFESSOR:Well,the Olympic marmots inhabit meadows high in the Olympic Mountains where the weather conditions are much harsher so there's a lot more wind and snow.The growing season only lasts about two to three months.So,in that much shorter period of time,all of the Olympic marmots,male and female,eat,play,work,and nurture the young together.

Because the climate is so harsh,cooperation increases the survival rate of the Olympic marmots.They keep their young at home until they're physically able to survive on their own.This could explain why the social behavior of the Olympic marmots is so unlike that of the eastern marmots.

二、Marmots托福聽(tīng)力中文翻譯：

旁白：在生物課上聽(tīng)一節(jié)課的一部分。

女教授：在今天的討論中，我們將回顧一些動(dòng)物行為如何適應(yīng)環(huán)境的案例研究。現(xiàn)在，你必須了解兩種動(dòng)物：東部土撥鼠和奧林匹克土撥鼠。

土撥鼠是嚙齒動(dòng)物。。。它們是體型巨大的地松鼠，大約一只普通家貓的大小，它們生活在各種各樣的棲息地。根據(jù)這項(xiàng)案例研究，盡管旱獺一年中大部分時(shí)間都在冬眠，但它們?nèi)匀槐徽J(rèn)為是動(dòng)物行為研究的優(yōu)秀對(duì)象。為什么會(huì)這樣？

男學(xué)生：嗯，當(dāng)它們不冬眠的時(shí)候，你可以在開(kāi)闊的地方找到它們，它們白天非?；钴S，這使得它們很容易被觀察到，對(duì)嗎&nbsp；

女教授：嗯哼。那么，首先讓我們討論一下東部土撥鼠。它們居住在北美東部地區(qū)，那里氣候溫和，生長(zhǎng)季節(jié)一年至少持續(xù)五個(gè)月。。。也就是說(shuō)，當(dāng)它們進(jìn)行所有的交配、玩耍和進(jìn)食時(shí)。

男學(xué)生：哦，我明白了。。。起初，我不知道“生長(zhǎng)季節(jié)”是什么意思，但現(xiàn)在我明白了。這是他們成長(zhǎng)所需的時(shí)間，對(duì)嗎？那么，要五個(gè)月？

女教授：嗯？哦，我很抱歉，但不，這與此無(wú)關(guān)。這與東部土撥鼠的生長(zhǎng)時(shí)間無(wú)關(guān)，而是當(dāng)食物可用時(shí)。也就是說(shuō)，當(dāng)它不被雪覆蓋，草上也沒(méi)有霜凍覆蓋，植物、草藥和土撥鼠喜歡吃的花的營(yíng)養(yǎng)部分&nbsp；所以，“生長(zhǎng)季節(jié)”指的是他們所吃食物的可獲得性。好啊那么現(xiàn)在，你如何描述東部土撥鼠的社會(huì)習(xí)性呢？

女生：嗯，它們真的很有領(lǐng)土感，很孤獨(dú)，甚至對(duì)其他東部土撥鼠也很有侵略性。他們的交配儀式就是這樣。。。不近人情的

女教授：嗯哼?，F(xiàn)在，當(dāng)它們?cè)诖禾鞆亩咧谐霈F(xiàn)時(shí)，交配過(guò)程開(kāi)始了。對(duì)它們來(lái)說(shuō)，好吧，它們聚在一起交配，然后分道揚(yáng)鑣。然后，大約在出生六到八周后，后代離開(kāi)了母親。

女生：真的，就六周？孩子們有沒(méi)有可能這么年輕就自己生下來(lái)；

女教授：嗯，他們似乎還沒(méi)有準(zhǔn)備好面對(duì)現(xiàn)實(shí)世界。。。因?yàn)樗麄兪牵挥涀?，它們成熟得很快，天氣也很好。此外，它們生活在開(kāi)闊的田野里，那里有許多可食用的植被。因此，大約在出生六周后，東部土撥鼠的年齡才足以在溫和的環(huán)境中生存；那么，這與他們的行為有什么關(guān)系呢？

女生：哦，我明白了。因?yàn)?，氣候還不錯(cuò)，東部土撥鼠不必太依賴彼此，它們也不需要像家人一樣呆在一起才能生存。

女教授：嗯哼。相比之下。。。奧林匹克土撥鼠。。。那他們呢？

女學(xué)生：嗯，他們作為一個(gè)家庭住在一起，照顧他們的孩子，直到他們至少兩歲。它們彼此非常友好，我真正喜歡的是，它們甚至有問(wèn)候儀式，它們一點(diǎn)也不像東部土撥鼠那樣咄咄逼人和領(lǐng)土擴(kuò)張&nbsp；所以，嗯，他們的社交行為與東部土撥鼠有很大的不同，因?yàn)樗麄兩畹臍夂?？這看起來(lái)太奇怪了！

女教授：哦，奧林匹克土撥鼠棲息在奧林匹克山脈高處的草地上，那里的天氣條件要惡劣得多，所以有更多的風(fēng)和雪。生長(zhǎng)季節(jié)只持續(xù)大約兩到三個(gè)月。因此，在更短的時(shí)間內(nèi)，所有奧運(yùn)會(huì)土撥鼠，無(wú)論男女，都會(huì)一起吃、玩、工作和養(yǎng)育幼崽。

由于氣候如此惡劣，合作提高了奧林匹克土撥鼠的存活率。他們把孩子留在家里，直到他們身體上能夠獨(dú)立生存。這可以解釋為什么奧運(yùn)會(huì)土撥鼠的社交行為與東部土撥鼠如此不同。
