情态动词+have done变反义疑问句时的注意事项和规则有哪些
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?
你一定把这事告诉她了,是吗?
再问： 那些属于明确的过去时间状语状语呢？
再答： last night, yesterday, last year, 1998, 等等
