When he came back,he found the bag he had left ______ over the seat was gone.

题目

When he came back,he found the bag he had left ______ over the seat was gone.
A hanging B hung选哪个?怎么判断的?

答案

选a
he found后面是宾语从句 这个从句的主语是the bag 系表是was gone
所以不能再加入动词 而hanging作为动名词 则可以
hanging over the seat 做the bag 的定语 来修饰 the bag
