特殊的反意疑问句
You must have stayed at hotel last night,_____?
A.mustn't they B.haven't they
C.didn't they D.hadn't they

Answer 1

选B.this called Tag question.A tag ending is added to the end of a sentence,and it makes the sentence into a question.so这两部分句子中的主语同指一人或事物,在时态、人称、数上应保持一致 must is modal,it means the prediction.if you choose mustn't they,the meaning of must would change.意思说如果变了must,整个句子的语气就变了.强调的是必须...,改变作者的意思了.
