谢邀答。咦?什么情况?怎么不是同一个人呢?
赞同以上老师们的答复。把它按照习语之类的来看待就行了吧,何必去细究它内部的具体成分啥的呢?懂其含义然后会用是首位的。从我个人的角度来看,这是在做无用功,特别是如果积累不够就去追究这些东西,没有意义,对学习没啥实际帮助而且可能容易走火入魔剑走偏锋。
Collins:have nothing to do with (or be nothing to do with)=have no connection with
类似的表达还有have something to do with…, have to do with…
其他字典的解释:
have nothing to do with:
Also, not have anything to do with.
1.Be irrelevant, be unrelated, as in Their visit has nothing to do with the holiday. [Early 1600s]
2. Avoid, as in Dad insisted that we have nothing to do with the neighbors, or I won't have anything to do with people who act like that. [Early 1600s] Also see have to do with.
它标注了Early 1600s,说明这个表达已经很有年头了,或许是由其他表达方式逐步演化过来的。
