Question

英语语法
My letter,___C__to the wrong number,reached him late.
A.to have addressed B.being addressed
C having been addressed D.to have been addressed
为什么这里用主动形式having?letter可以主动发出动作吗
这是独立主格吗 为什么不是have been addressed?

Answer 1

用完成时强调这个动作发生在主句动作前
having been addressed 里面包含了被动语态
不是独立主格结构,属于分词做状语
独立主格结构里会有一个主语；
比如He was lying on the grass, his hands crossed under his head
后面半句就是独立主格,his hands 是主语
