Question

what is he being accused of? 什么句型？ You know that having been subject to arrest.为什么having

这是电影台词，剧中女主角丈夫被拘禁，她去问警察局
-what is he being accused of?
-I'm sorry, but I can't tell you.
-Oh, come on. You know that having been subject to arrest. I have the right to know the charges.

Answer 1

know that 后面加宾语，having been应该是动名词做宾语。也就是you know that 。。
what is accused of。是一个特殊疑问句。因为外国电影中多是使用俚语，有时候是不符合语法规则的。我觉得正确的应该是what is the subject he is accused of？
关于其它的解释如楼上的。
不用管太纠结

Answer 2

楼上威武
be accused of 固定用法 被指控...
having done 表示 动作已完成已发生

Answer 3

be accused of 控告。what is he being accused of?进行时的被动语态。having been sub,,,动名词短语做主语。

追问

你能详细点吗？
