Question

I don't think that the boy can solve the problem,-------? A.can he B.can't he C.do you D.don't you

Answer 1

当主句的主语为第一人称时，其后的简短问句应与从句相一致。例如：
　　I expect our English teacher will be back this weekend, won't she/he?
　　值得注意的是，当这些动词后接的宾语从句的否定转移到主句时，其仍属否定句，故其后的简短问句应用肯定式，而非否定式。例如：
　　I don't believe that he can translate this book, can he?
　　此类句子的回答同"前否后肯"型反意疑问句一样，如上述后一个句子，若双胞胎已经到了，则回答为"Yes, they have."；若尚未到达，使用"No, they haven't."。

所以这题：I don't think that the boy can solve the problem,-------?
A.can he B.can't he C.do you D.don't you

选A

Answer 2

答案选A.can he
这是反意疑问句
