（1）动词不定式并非表示将来的、未发生的动作。例如：
He was the first to come here yesterday. 此句中的 to come 就表示过去的动作。
（2）have/be nothing to do with sb/sth的意思是“与某人 /某事毫不相干；与某人/某事无关”，作为一个句型记忆即可，没有必要作过细的分析。

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。
