Only when he had done it () that he had made a mistake.
A. had he come to understand B he came to understand c he had come to understand
D. did he come to understand 老师说这题答案是D，我也知道是倒装，但A为什么不行？
A. had he come to understand B he came to understand c he had come to understand
D. did he come to understand 老师说这题答案是D，我也知道是倒装，但A为什么不行？
因为he come to understand 这个动作发生在 he had done 之后 所以应该用一般过去时
倒状的句子是一个一般过去时。
首先句子的意思是：当他干完了才明白自己犯错误了。
did 的 动作是 come 还原下 就是 he only come to understand
