A squirrel, merrily leaping on the branches of an oak tree, accidentally missed its hold and fell upon a lion who lay at the trunk, basking in the shade.

一只松鼠在橡树上欢快地跳来跳去，一不小心从树上跌落下来，恰巧落在一头正在树荫下酣睡的狮王身上。

The lion consented to this; and when the squirrel was out of his reach he thus addressed him, "You seek to know how I am always merry."

于是松鼠就跳到了狮子够不到的地方，接着说：“您问我为什么总是这么快乐，是道德给了我愉快的心情。
