a black sheep
讲解：旧时牧羊人不喜欢黑色的，因为迷信认为黑色是魔鬼的化身，会给人带来厄运或灾祸。
另外，黑羊毛不如白羊毛值钱，这也是一个原因。牧羊人会因羊群中有黑羊而诅咒不已。
因此，a black sheep就引申为“败类”“败家子”的意思，与汉语中的“害群之马”相近。
例如：Joe is the Black sheep of his family. He splashed nearly a few years.
乔是个败家子。几年内他竟然挥霍掉十几万美元。
情景对话：
A :I don't know how John can put up with his son, who fools around without working.
A :我不知道约翰为什么能容忍他的儿子整天不工作，瞎混日子。
B :He's out of John's hands. Nothing he can do about such a black sheep.
B :他不服约翰的管教，对这样一个败家子，约翰无可奈何。
A :If I were him, I would give him a good talking-to. I would insist on his stopping fooling around like that.
A :如果我是约翰，我会教训他一顿，坚持不能让他再这么瞎混了。
