has she?
首先,一般反義疑問句如果是賓語從句,以主句的主語為基準,但是i think 是例外,主語根據(jù)從句的主語來定.
其次,從句中的never看做否定詞,表否定意思,所以把從句看做一個否定句.前否后肯,另外時態(tài)要與從句一致,用現(xiàn)在完成時（have/has+過去分詞）,所以要用has she
如：he thinks he has never watched such a great film,has he?
注意點：在i think 這種特殊情況中,如果遇到開頭是i don`t think……的話,要把do not 中的not 還原到從句中,看作否定.
如：i dont think he is a good teacher,is he?
