Ⅰ. 过去完成时:形式:“助动词 had+过去分词”构成。
1. 表示在过去某一时间或动作之前已经完成了的动作。
它表示这个动作发生的时间是“过去的过去”;这一过去时间可用 by, at, before 等构成的短语或 when, after, until 等引导的从句或通过上下文来表示,如:
By the time he was twelve, Edison __________(begin) to make a living by himself.
2. 表示由过去某一时间开始,延续到过去另一时间的动作。
这个动作可能还要延续下去。常和for 或 since 引导的表示一段时间的短语或从句连用。
He ____ _____ (live) in New York for ten years before he moved to Boston.
用于表示与过去事实相反的虚拟条件从句。如:
If he _________________(see) you yesterday, he ______________(ask) you about it.
用在间接引语或宾语从句中。放在像said, told, thought, wondered 等过去时动词的后面,表示在这些动作之前已经发生的行为。
