哦，陈磊同学的问题很好。大家正值青春期，所以渐渐地会开始关注两性的问题。这个呢，是人类的本能。过会儿呢，我们要看一个青春期性教育的片子。男生跟着我去101室，女生跟着班长去102室。

Chen Lei's question is a very good one. You're all just entering puberty, so you'll gradually start to notice things about the opposite sex. This is human instinct. In a little while, we'll watch an adolescent sex education film. The boys will go with me to room 101, and the girls will go with the class monitor to room 102.
