what happened to 和 what had happened to的区别是什么?
what happened to 是一个一般过去时的问句,后跟的时间状语是类似yesterday等一般过去时的时间状语;而what had happened to是过去完成时,后跟的时间状语是类似before you got to the station等这样的时间状语,就是以这个过去的时间点作为参照点,那么这个参照点之前的动作用过去完成时.

what happened to 过去式,表示sb, sth曾经发生了什么事。
what had happened to 过去完成式,表示sb, sth在过去的过去曾经发生了什么事。

过去时只讨论过去,过去完成时表示的是过去的过去,即对过去的影响。过去时没有这一层含义。
