You can drive an unwounded lion--he'll move on ahead of a noise--but a wounded lion's going to charge.

你可以去撵一头没受伤的狮子——它一听到闹声，就会往前——可是一头受了伤的狮子就会扑上来。

That was my excuse to myself, although I knew it was wrong of me to leave only two unwounded men to guard the stockade.

这只是我自己的借，尽管我知道只留下两个未受伤的人守卫木屋是错误的。
