① 当陈述部分为I think (believe, suppose) that...等时,疑问部分通常与从句保持一致(注意否定的转移):
I think that it is too short, isn’t it? 我认为它太短了,对不对(它太短吗)?
I don’t think he will come, will he? 我认为他不会来,对吗(他会来吗)?
② 由①可知此处的反意疑问句应与从句保持一致,would have done表示对过去情况的推测,且有明显的时间状语 last night, 故用过去时 didn't you .
如果还不了解就Hi我吧.

must表示“一定、肯定”等推测意义时,在反意问句中,疑问部分一般不用情态动词,而和must后的动词相一致。
本句如果没有情态动词must来表达推测意义时,句子会是:
You missed the train last week.
所以,反意问句应为:
You missed the train last week, didn't you?...

因为该must在里面是表推测 就相当于 you missed the train last week. 根据前肯后否的 反义疑问句 因此 就只能选择C
希望能够帮到楼主

首先,答案是翻译疑问句,在这句话中must是表示推测,必定,一定。所以这句话must就不能作为实义动词,选项1表示禁止 其次,have missed表示完成时态 miss是真正的实义动词。故选3 needn't you 表示不必
例如 Must I clean the dining room at once? 我必须马上打扫餐厅吗?
—Yes, you must. 是的,你...
