I don’t think he could have done such a stupid thing last night,__________?
A. do I
B. could he
C. did he
D. has he
题目解答
答案
C. did he
解析
反意疑问句的解题关键在于主句和从句的逻辑关系以及动词时态的匹配。本题中,主句为否定结构"I don't think",从句使用了情态动词完成式"could have done"。需注意:
- 反意疑问部分的主谓需与从句中的主谓保持一致;
- 从句中的"could have done"表示对过去的推测,疑问部分应使用did(对应动词原形do的过去式)。
句子结构分析
原句为复合句,包含主句和从句:
- 主句:I don’t think(否定结构)
- 从句:he could have done such a stupid thing last night(从句动词为could have done)
反意疑问句规则
- 主句为否定时,疑问部分用肯定形式;
- 从句中的动词决定疑问部分的助动词:
- 从句动词为could have done(情态动词完成式),对应疑问部分的助动词为did;
- 主谓与从句一致,故疑问部分为did he。
选项排除
- A. do I:主谓与从句不一致;
- B. could he:未体现"have done"的完成式;
- D. has he:与从句时态(过去式)不符;
- C. did he:正确匹配从句动词时态和结构。
