请教一道非谓语动词的题The old couple returned to their hometown ten years later,_____ everything completely changed there.A.found B.having found C.to have found D.to find这题正确答案是D,但是我一直想填finding,但是选项里没有.1,为什么是D,老夫妇回到家乡,发现一切都变了,是否因为发现变化的动作发生在回到家乡以后,所以用不定式表示先后呢?我记得非谓语动词里,有一个“紧接着先后发生”,用ing也是靠谱的.2,如果选项里有finding,选的话算不算对.
