二、单元语法：过去完成时

过去完成时表示在过去某一时间点以前即“过去的过去”已经发生的动作。

Mr. Black told me that he had seen the movie three times.

布莱克先生告诉我他已经把这部电影看了三遍了(“看”在“告诉”之前。)

过去完成时要注意以下几个方面：

⑴过去完成时表示在过去某一时间或动作之前已经发生或完成的动作。

它表示动作发生的时间是“过去的过去”。

⑵过去完成时的结构是：

肯定由“助动词had(用于各种人称和数) + 过去分词”构成

否定式：had not + 过去分词

缩写形式：hadn’t

⑶过去完成时的时间状语：

①表示过去某一时间可用by, before等构成的短语。

We had finished our homework before 10 o’clock. 我们十点钟之前就完成了作业。

②可能通过when, before等引导的从句表示。

When I got there, the train had left. 当我到那儿时，火车已经开走了。

③过去某一时间通过上下文来表示。

Kate hadn’t studied hard, so she didn’t pass the exam yesterday.
