I think he must be a teacher,isn't he?I think you are a student,aren't you?I don't think she likes English,does she?I don't think she is a good student.is she?当主句的主语是第一人称时,反义疑问句和从句一致,并且将否定转移,比如I don't think she is a good student,is she?当主句主语是非第一人称,反义疑问句和主句一致。
为您解答如下-----------
1,主语是第一人称时,含有think / suppose / believe 宾语从句的反义疑问句,其简略问句,要根据从句来提问,同时如果主句用了否定,要否定转移(即当作从句否定)。
2,含有must be的反义疑问句,当must be表示“推测”的意思时,简略问句要根据be的实际时态来提问;当must是表示“必须”的意思时,简略问句要用must / mustn't来提问。
依照上述规则:1,I think he must be a teacher,isn't he?
2,I think you are a student,aren't you?
3,I don't think she likes English,does she?
4,I don't think she is a good student,is she?
祝你进步
