当陈述部分有情态动词must,且是must+have done结构 表示对过去的情况进行推测(一般句中有明确的过去时间状语),问句要根据陈述部分谓语的情况用“didn't+主语”或“wasn't/weren't+主语”;如果强调动作的完成(一般没有明确的过去时间状语),问句要用“haven't/hasn't+主语”.
She must have read the novel last week,didn't she?
她上星期一定读了这本小说,是吗?
You must have told her about it,haven't you?
The old man must have been a Swedish.
改否定句

参考2:
.must的否定形式表示“禁止/不许”,不能表示推测;
mustn't have done sth此种形式的确不存在,
must have done sth“一定做过某事”的否定形式是can't/couldn't have done sth,
意思是“不可能做过某事”.
