【單元語法】本單元語法：過去完成時。
過去完成時表示在過去某一時間點以前即“過去的過去”已經發生的動作。
mr. black told me that he had seen the movie three times.
過去完成時要注意以下幾個方面：
⑴ 過去完成時表示在過去某一時間或動作之前已經發生或完成的動作。
它表示動作發生的時間是“過去的過去”。
⑵ 過去完成時的結構是：
肯定由“助動詞had(用于各種人稱和數) + 過去分詞”構成
否定式：had not + 過去分詞 縮寫形式：hadn’t
⑶ 過去完成時的時間狀語：
① 表示過去某一時間可用by, before等構成的短語。
we had finished our homework before 10 o’clock.
② 可能通過when, before等引導的從句表示。
when i got there, the train had left.
③ 過去某一時間通過上下文來表示。
kate hadn’t studied hard, so she didn’t pass the exam yesterday.
