表示在過去某一時刻前完成了的動作，也可以說過去的時間關於過去的動作。即“過去的過去”。可以用by,before等介詞短語或一個時間狀語從句來表示，也可以用一個表示過去的動作來表示，還可能透過上下文來表示。

例如：By nine o’clock last night,we had got 200 pictures from the spaceship.

到昨晚9點鐘，我們已經收到200張飛船發來的圖片。

（2）表示由過去的某一時刻開始，一直延續到過去另一時間的動作或狀態，常和for,since構成的時間狀語連用。

當車來的時候，我在車站已等了20分鐘。

He said he had worked in that factory since 1949.

他說自從1949年以來他就在那家工廠工作。

（3）敘述過去發生的事情，在已敘述了過去發生的事情後，反過來追述或補述以前發生的動作時，常使用過去完成時。

如：Mr.Smith died yesterday.He had been a good friend of mine.

史密斯先生昨天去世了。他以前是我的好友。

I didn’t know a thing about the verbs,for I had not studied my lesson.

我對動詞一無所知，因為我沒有好好學習功課。

（4）在含有定語從句的主從複合句中，如果敘述過去的事，先發生的動作常用過去完成時。

例如：I returned the book that I had borrowed.

我已歸還了我借的書。

She found the key that she had lost.

她丟失的鑰匙找到了。

（5）過去完成時常常用在told,said,knew,heard,thought等動詞後的賓語從句（或間接引語）中，這時從句中的動作發生在主句表示的過去的動作之前。

例如：He said that he had known her well.

他說他很熟悉她。
