I think Mr. Smith must know our englis teacher,_____?
A. don't I
B. doesn't he
C. mustn't I
D.mustn't he

解题思维步骤如下：
1.“反意疑问句中,如果陈述句是复合句,且主句的主语和谓语分别是I think,I guess,I suppose,I believe,I imagine等时,反意疑问句的人称和数要与从句保持一致;如果主句的主谓不是以上结构时,则反意疑问句的人称和数要与主句保持一致.” 那么会考虑选D
2.“关于几个情态动物must,may的否定形式,并不是简单的加not.由于must有二个意思,一是表示必须,一是表示猜测,表必须时的否定是need not,而表猜测呢?首先可以排除不是mustn't,因为mustn't是may的否定形式”,所以不可以选D.
3.那么再结合第一点,因此本题意义上应该选B,语法上因为其它三个都要排除,也只能选B.
