请懂人帮我看一下这两个句子关于语法上的一个问题：
（1）He said,"Did you see him last night?"
——He asked if I had seen him the night before.
(2) "When did you go to bed last night?"Father said to Anna.
——Father asked Anna when she went to bed the next before.
为什么第一个句子改成间接引语的时候用的是过去完成时,而第二个句子用的是一般过去时?

解答

当变成宾语从句,主语是过去式时,如果从句动作发生在主句动作之前,就是过去的过去,要用过去完成时.
He asked if I had seen him the night before.
前个晚上看见他是发生在ask 之前,所以用过去完成时.
