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.
b
D
I think should choose B
选择D
因为 I think 加宾语从句时,构成反意问句时,看从句,不看主句。
eg: I think he is a good student, isn't he?
B,楼上说的对,但是此处不宜用must引导反意疑问句。最好用单数第三人称
must在这里不是情态动词 它表示一种肯定的猜测
所以我认为应该用 B
D.
第一人称+think不参加否定疑问
