问题补充：
----I think the teacher is wrong, ?
----No, I don think so
A. don you
B. don I
C. doesn he
D. doesn she
答案：
(答案→)A. don you
B. don I
C. doesn he
D. doesn she
解析：此题容易误选C或D，因为按照语法规则，I think后接宾语从句时，其反意疑问句与从句保持一致，但是退一步，即使按此规则，其反意疑问句也应是isn he或isn she之类的，而不是像C或D那样用doesn he和doesn she。综合四个选项，最佳答案为A，don you为don you think so之省略。
