一、Marmots托福听力原文：

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托福听力中文翻译：

旁白：在生物课上听一节课的一部分。

女教授：在今天的讨论中，我们将回顾一些动物行为如何适应环境的案例研究。现在，你必须了解两种动物：东部土拨鼠和奥林匹克土拨鼠。

土拨鼠是啮齿动物。。。它们是体型巨大的地松鼠，大约一只普通家猫的大小，它们生活在各种各样的栖息地。根据这项案例研究，尽管旱獭一年中大部分时间都在冬眠，但它们仍然被认为是动物行为研究的优秀对象。为什么会这样？

男学生：嗯，当它们不冬眠的时候，你可以在开阔的地方找到它们，它们白天非常活跃，这使得它们很容易被观察到，对吗&nbsp；

女教授：嗯哼。那么，首先让我们讨论一下东部土拨鼠。它们居住在北美东部地区，那里气候温和，生长季节一年至少持续五个月。。。也就是说，当它们进行所有的交配、玩耍和进食时。

男学生：哦，我明白了。。。起初，我不知道“生长季节”是什么意思，但现在我明白了。这是他们成长所需的时间，对吗？那么，要五个月？

女教授：嗯？哦，我很抱歉，但不，这与此无关。这与东部土拨鼠的生长时间无关，而是当食物可用时。也就是说，当它不被雪覆盖，草上也没有霜冻覆盖，植物、草药和土拨鼠喜欢吃的花的营养部分&nbsp；所以，“生长季节”指的是他们所吃食物的可获得性。好啊那么现在，你如何描述东部土拨鼠的社会习性呢？

女生：嗯，它们真的很有领土感，很孤独，甚至对其他东部土拨鼠也很有侵略性。他们的交配仪式就是这样。。。不近人情的

女教授：嗯哼。现在，当它们在春天从冬眠中出现时，交配过程开始了。对它们来说，好吧，它们聚在一起交配，然后分道扬镳。然后，大约在出生六到八周后，后代离开了母亲。

女生：真的，就六周？孩子们有没有可能这么年轻就自己生下来；

女教授：嗯，他们似乎还没有准备好面对现实世界。。。因为他们是；记住，它们成熟得很快，天气也很好。此外，它们生活在开阔的田野里，那里有许多可食用的植被。因此，大约在出生六周后，东部土拨鼠的年龄才足以在温和的环境中生存；那么，这与他们的行为有什么关系呢？

女生：哦，我明白了。因为，气候还不错，东部土拨鼠不必太依赖彼此，它们也不需要像家人一样呆在一起才能生存。

女教授：嗯哼。相比之下。。。奥林匹克土拨鼠。。。那他们呢？

女学生：嗯，他们作为一个家庭住在一起，照顾他们的孩子，直到他们至少两岁。它们彼此非常友好，我真正喜欢的是，它们甚至有问候仪式，它们一点也不像东部土拨鼠那样咄咄逼人和领土扩张&nbsp；所以，嗯，他们的社交行为与东部土拨鼠有很大的不同，因为他们生活的气候？这看起来太奇怪了！

女教授：哦，奥林匹克土拨鼠栖息在奥林匹克山脉高处的草地上，那里的天气条件要恶劣得多，所以有更多的风和雪。生长季节只持续大约两到三个月。因此，在更短的时间内，所有奥运会土拨鼠，无论男女，都会一起吃、玩、工作和养育幼崽。

由于气候如此恶劣，合作提高了奥林匹克土拨鼠的存活率。他们把孩子留在家里，直到他们身体上能够独立生存。这可以解释为什么奥运会土拨鼠的社交行为与东部土拨鼠如此不同。
