　　2015年9月5日托福听力真题预测(小范围)：

　　Listen to a lecture in a biology class.

　　女 Professor: 好，在今天开始讲课之前，我们先 review 一下上节课的内容。上节课，我们讲了(We have talked about)神经元细胞(电脑中心的框中打出：neuron), 以及其工作的原理(function), 有谁能回忆起来?

　　Professor=

　　All right. 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. Let''s start with the play-as-preparation hypothesis. Jerry, can you explain it?

　　Male Student=

　　Yeah, Play-as-preparation. Young animals play in order to get really good at certain specific things they will need to do when they are adults, things like chasing, pouncing, climbing. In other words, they play in order to practice survival skills, like movements used in hunting and fighting. That hypothesis makes a lot of sense, like, maybe the most sense of all the theories we read about.

　　Professor=

　　And what leads you to that conclusion?
