Animal Domestication
For thousands of years， humans have been able to domesticate， or tame， many large mammals that in the wild live together in herds. Once tamed， these mammals are used for agricultural work and transportation. Yet some herd mammals are not easily domesticated.
A good indicator of an animal‘s suitability for domestication is how protective the animal is of its territory. Non-territorial animals are more easily domesticated than territorial animals because they can live close together with animals from other herds. A second indicator is that animals with a hierarchical social structure， in which herd members follow a leader， are easy to domesticate， since a human can function as the“leader”。
Narrator
Now listen to part of a lecture on this marketing in an ecology class.

Professor
So we‘ve been discussing the suitability of animals for domestication…… particularly animals that live together in herds. Now， if we take horses， for example…… in the wild， horses live in herds that consist of one male and several females and their young. When a herd moves， the dominant male leads， with the dominant female and her young immediately behind him. The dominant female and her young are then followed immediately by the second most important female and her young， and so on. This is why domesticated horses can be harnessed one after the other in a row. They’re“programmed” to follow the lead of another horse. On top of that， you often find different herds of horses in the wild occupying overlapping areas——they don‘t fight off other herds that enter the same territory.But it‘s exactly the opposite with an animal like the uh， the antelope…… which…… well， antelopes are herd animals too. But unlike horses， a male antelope will fight fiercely to prevent another male from entering its territory during the breeding season， ok——very different from the behavior of horses. Try keeping a couple of male antelopes together in a small space and see what happens. Also， antelopes don’t have a social hierarchy——they don‘t instinctively follow any leader. That makes it harder for humans to control their behavior.[2 seconds]NarratorThe professor describes the behavior of horses and antelope in herds.

本题的阅读部分是关于什么样的野生哺乳动物随便驯化的，讲到non-territorial动物比较随便驯化；还讲到有高、初级别之分的动物比较随便驯化。听力部分从比较详细的角度，描绘了野马为什么随便驯化，而羚羊却不随便驯化。
考生在回答题目时，需要将阅读中的笼统的不雅观点与听力中的具方款式有效的连系起来。值得留意的是，一个好的白话谜底应该让那些没有读过阅读漫笔、没有听过听力篇章的人能年夜白你讲的是什么。
