5、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等動詞后的賓語從句（或間接引語）中，這時從句中的動作發(fā)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。 I thought I had sent the letter a week before. 我認為我一星期前就把信寄出去了。 （6） 狀語從句：在過去不同時間發(fā)生的兩個動作中，發(fā)生在前，用過去完成時；發(fā)生在后，用一般
