依据一条简单的规则:把该句变成真实的语气,再根据真实的语句使用附加问句,如:
1.It must have rained last night,_____?
真实句It rained last night.再附加问句didn't it?所以答案为didn't it?
2.She must have seen the film before,_____?
真实句She has seen the film before.再附加问句hasn't she?所以答案为hasn't she.

must have done 表推测时,附加疑问句该怎么样用? MUST当推测时表一定等于HAVE TO吗. must表推测时的用法? One must be honest,mustn't one,这个句子怎么理解,不是说当must表示推测时,附加疑问句不情态动词could与must表推测时反意疑问句一样吗. have to be 和 must be 表推测时的区别关于must表推测时的过去时表达 must have done 与 may have done 的反义疑问句 must have done的反义疑问句 must can 表推测时,是情态动词还是一般的动词? may、can、must、should、can’t表推测时的区别 ought to与推测时与must的区别
