I was going to start showing you some examples, but I think, rather than doing that, I'm going to stop here, I'm going to give you two minutes back of time, but I want to just point out to you that we are going to have fun next week, because I'm going to show you what in the world that has to do with efficiency.

我想再给你们讲解一些例子，但是我想想还是算了吧，给你们两分钟休息时间,但是我想告诉你们,我们下周的课,会很有意思,我会告诉你们,到底是什么决定了效率。
