she must have been forty.变反意疑问句!They must have seen the film.反意疑问句The old man must have been a Swedish.否定句My father must have gone to work.反意
改反意疑问句：
she must have been forty,hasn't she?
They must have seen the film,haven't they?
My father must have gone to work,hasn't he?
参考1：
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
The old man can't have been a Swedish.
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”.
