托福听力真题原文+题目+答案+mp3下载：human interference affects the way animals behave

The activities of humans are increasingly entering closer to the natural habitats of many wild animals. Today, I want to talk about how this increased human interference affects the way animals behave around humans. Well, many wild animals live in groups, and we know that it's common for these types of animals to live in a social hierarchy. This social hierarchy dictates how the members of the group function since every member of the group is assigned a rank.

Okay, now let's look at it more closely. The leader, the alpha, is mostly the dominant male or female that commands all of the other animals in its group. The hierarchy may change if a member is forced to leave from the pack or if the pack accepts a new member.In addition, if an alpha dies or gets replaced, the alpha position is always filled from within the pack. Also don't forget that there is also the second in command, the beta. The beta is submissive only to the alpha and dominates every other member of the group. Being alpha has certain privileges, like being the first one to eat food; subordinate members all have to wait their turn. And the alpha is usually the biggest or the strongest member of the group. So what hap-pens to a group of animals living in a social hierarchy when they come into contact with humans? How does their behavior change?Does it change?
