Question

I don't think her aunt has been to Guilin,_?A.has she B.hasn't she C.do you D.don't you 求分析~

Answer 1

A.has she

陈述部分是“I/We think (believe, suppose, consider) + that从句”时，简略疑问部分应和从句相一致，但须注意否定前移的现象。
　　I supposed Li Ming had closed the windows, hadn’t he? 我想李明已经关了窗户，是不是？
　　I don’t think she’s right, is she? 我认为她不对，是不是？

Answer 2

　　A.has she
　　反义疑问句中，前面的陈述句如果带宾语从句，而且主句中的主语谓语动词为表示人心理活动的动词并且主语为第一人称代词(I或we)，这时不对主句反义疑问，而要对从句提问，再者改句句为否定的转移现象，所以前面的陈述句应视为否定句，所以疑问部分用否定。
