一个句子：
You must have left here yesterday.（改为反义疑问句）
我记得must表猜测时看它后面的词.它现在后面的词是have
去掉must还原句子后应该是You have left here yesterday.
也就是现在完成时.现在完成时的反义疑问句应该是 haven't you?
老是给的答案是didn't he?我觉得不对.
然后老是把这个句子的yesterday去掉了
成了：You must have left here .（改为反义疑问句）
老师说这句子成这样后改反义疑问句就是加上：hasn't you?
第一个句子明明是完成时,问什么不用have进行反问?
而第二个句子就用have反问了?
我觉得老师把第一个句子当成了过去完成时了..
请解决下这2个句子的反义疑问句~
有个打错了第二句老师改的是
haven't you

第二个句子不是过去完成时
是现在完成时

请问第一个句子是过去完成时吗?
过去完成时中不能出现yesterday.
你的这句话 “反义句与must后的动词一致”
现在must后的动词是have,因为有yesterday,所以是had
为什么不是hadn't you?

第一个句子有yesterday做时间状语 只有过去式跟具体时间 所以答案是didn't you 你记不记得有这么个句式——should have done sth表示应该做却没有做 同样的 could have done表示能做却没有做 这里的must have done表示推断 并不是完成时 是情态助动词加have done的用法
第二个句子就是你理解的那样 因为没有具体时间限制 就是have done完成时
