原文如下：Alright, I hope you all had a chance to finish the assigned readings about animal play, because I want to spend some time discussing the different viewpoints presented in those articles.~
30.One of the students brings up the example of play fighting among wolf pups. What does this example lead him to believe? 00:44 A. That wolves are especially violent animals
B. That the play-as-preparation hypothesis is probably correct C. That wolves seldom engage in self-handicapping
D. That the results of a recent study are probably not reliable
答案：B, 解析：问答题，再解释 play as preparation 时，教授问 jerry 是怎样得到那个结论的，学生 jerry 用了 wolf 的例子。注意问答点
原文如下：Professor: And, what leads you to that conclusion?
Jerry: Well, like wolves, the young pups, they fight a lot and bite, you know, not to hurt each other, but, just seems obvious why those wolf pups play like that,
31. Which statement best expresses the professor’s opinion of the play-as-preparation
hypothesis? 01:41 A. B. C. D.
It is well supported by available evidence
It may apply only to certain species of animals It does not explain some important aspects of play It is particularly useful explaining human behavior
答案：C 解析：这道题，男生解释完了，女生挑刺，说动物孩童时玩耍的技能同成年后的行为完全不 同，后来教授态度表示同意，说明 play-as-preparation 并不能解释 play 的一些重要方面。 原文如下：
Female student：Oh, I don’t know about that. I mean, some of the things the young animal does while playing are totally different from the things they will do as an adult. ……
Professor: So this self-handicapping is important to take this into account before deciding to go with that first explanation, and in fact, there really isn’t much in the way of solid experimental evidence to support the play-as-preparation hypothesis.
32. What does the professor imply about self-handicapping?
Click on 2 answers 01:35
A. It commonly occurs in play but not in other activities B. It applies only to animal species that do not hunt for food C. It has been observed only in laboratory settings D. It contradicts the play-as-preparation hypothesis
答案：A, D
解析：细节题。说道这个 self-handicapping 一方面是只在游戏玩耍的时候用，不在真正的打 斗时候出现（这个教授也有解释），所以选 A，这个在听力原文中，那个女生有所解释，而 D，可以通过当时女生挑战男生关于 play-as-preparation 说明的时候证明，B 没有说 only 和 hunt for food。C, only laboratory setting 文章没有涉及，注意其它选项的 only 极限词汇。 原文如下：
Female student: Oh, I don’t know about that. I mean, some of the things the young animal does while playing are totally different from the things they will do as an adult. There was a really good example in second article. I can’t remember what it‘s called exactly… uh…self…
Female student: RIGHT! Self-handicapping, like during the fake fight…uh… a play fight, if one of
the animals is winning, the winning animal might just stop and give up its advantage
33. The professor discusses a study on the relationship between brain growth and play. What does that study conclude? 02:06 03:22 03:37
A. Patterns of brain growth are similar in animals that play and animals that do not play B. Excessive brain growth can sometimes limit an animal’s behavioral vocabulary C. Animals that do not play have less-developed brains than animals that play D. Animals without well-developed brains are seldom observed playing
答案：C
解析：文中有个词汇 apparently，明显的总结词汇，说明的正好是 C 项。
原文如下：Ah, yes. Let’s talk about that. As you say, play is much more than just pretend fighting or practicing other adult behaviors. Apparently, it also contributes to the development of a brain that’s flexible.
34. What does the student mean when she says this: 01:03
A. She is not familiar with the play behavior of wolf pups
B. She doubts that wolf pups fight as much as the other students implies C. She is not sure that she correctly understood the reading assignment D. She disagrees with the other student’s opinion about play behavior 答案：D 解析：重听暗示题，为了理解隐藏含义，也要联系上下文女学生明显不同意那个男生的观点， 后面的内容明显是对男生观点的反驳。
原文如下：Female student: Oh, I don’t know about that. I mean, some of the things the young animal does while playing are totally different from the things they will do as an adult. There was a really good example in second article. I can’t remember what it‘s called exactly… uh…self…
