Had the writer's money been stolen?

问题描述:

Had the writer's money been stolen?
可以把been换成was why?

不可以
这是过去完成时的被动语态的动词形式【 had been+ 过去分词 】
因为had 必须得和过去分词才能构成完成式,所以采用be 动词的过去分词been
请在客户端右上角评价点“满意”即可,It could be worse 这里的be怎么讲?先看这个:It was worse. (主系表)加了情态动词could 之后,由于情态动词后面所有的be 动词(am, is, are, was, were)都得是be, 所以便成了It could be worse这还是个主系表句型:It (主语)could be(系动词) worse (表语)
