she got to the station only to find that the train had left

问题描述:

she got to the station only to find that the train had left
从FINDS FOUND FINDING TO FIND中选一个答案,为什么是最后一个

是这样的:she got to the station only to find that the train had left,在这句话里,to find (that the train had left)是不定时做目的状语,意思是她去车站的目的是找.
