一道宾语从句题目
句型转换
"Why didn't you come here on time?'I wanted to know.
---I wanted to know _____you _____come here on time .
请问,第二个空是填didn't or hadn't.
i wanted to know why you hadn't come here on time.
宾语从句会受到主句的谓语时态影响,前面是wanted过去时,从句中就一定要用过去范畴的时态.(客观真理除外,例:The teacher told us that the earth moves around the sun.)
用了hadn't,是表示在i wanted to know 之前你没有来的动作,符合了过去完成时的用法
