有时，我甚至觉得自己像一个喜剧演员，迸发出一个又一个的笑话，使整个课堂哄笑不已。

She moved so fast it was as though she had Disapparated; one moment she was there, the next, she had squeezed between two guffawing witches and vanished.

Before you fall off your chair guffawing, insisting that you know happiness when you see it and that some economist couldn't possibly say anything helpful, listen up.

听到这些，你也许会笑得从椅子上滚下来。人们坚信，当他看到了幸福，就懂得了幸福。经济学家根本不可能给出什么妙方。
