构成
“助动词had (用于各种人称和数) + 过去分词”
概念
过去完成时表示某动作或状态在过去某一时间或动作之前已经发生或完成，它表示动作发生的时间是“过去的过去”。
句式
肯定句：主语＋had ＋过去分词＋…
否定句：主语＋ hadn’t ＋过去分词＋…
判断
依据
1. 由时间状语来判定
(1) by + 过去的时间点。
I had finished reading the novel by nine o'clock last night.
(2) by the end of + 过去的时间点。
到...为止
(3) before + 过去的时间点。
在...之前
2. 由“过去的过去”判定
(1) 宾语从句中: 当宾语从句的主句为一般过去时，且从句的动作先于主句的动作时，从句要用过去完成时。在told, said, knew, heard, thought等动词后的宾语从句。
如： She said that she had seen the film before.
(2) 状语从句 : 在时间、条件、 原因、 方式等状语从句中，主、从句的动作发生有先后关系，动作在前的，要用过去完成时，动作在后的要用一般过去时。如：When I got to the station, the train had already left.
(3)注意：before, after 引导的时间状语从句中，由于 before 和 after 本身已表达了动作的先后关系，若主、从句表示的动作紧接着发生，则主、从句都用一般过去时。如： After he closed the door, he left the classroom.
特殊疑问句：疑问词＋had ＋主语＋过去分词＋…？
一般疑问句：Had ＋主语＋过去分词…？　
(Yes, 主语＋had. / No, 主语＋hadn’t.)
