一日一句【31】过去完成时的含义

过去完成时的含义

示例：
I got to the theatre late. When I arrived, the show had already started.
我到剧场时已经晚了。入场时演出已经开始。

如果正在说的已经地过去的事，而双又说到比这更早一些时候发生的事情，就要用过去完成时：

He wasn’t exactly a stranger – I had met him once before.
他不能算是个陌生人—以前我已见过他一次。

I explained that I had forgotten to bring my student ID.
我就解释说我忘了带学生证。

过去完成式常常用在间接引语里，放在像said，told, asked, explained, thought, wondered等过去时动词的后面，表示在谈话或某想法之前已经发生的事情。

I told her that I had finished my term paper.
我告诉了她，我已写完学期论文了。

I wondered who had left the door open.
我不知道是谁让门开着。
