A hanging B hung选哪个?怎么判断的?

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?
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

a 现在分词在状语。

A hanging over 正在分词表 正挂在那。

选A…首先看句子中有谓语动词…所以要填非谓语动词…再看这里是主动的…用ing形式

首先判断这里应填一个非谓语动词，如果选b，则表示被动，而hang作挂讲时是不及物的，由此知选a
