4、事情后,反過(guò)來(lái)追述或補(bǔ)述以前發(fā)生的動(dòng)作時(shí),常使用過(guò)去完成時(shí)。 例如: Mr. Smith died yesterday.

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(guò)去完成時(shí)常常用在told,said,knew,heard,thought等動(dòng)詞后的賓語(yǔ)從句(或間接引語(yǔ))中,這時(shí)從句中的動(dòng)作發(fā)生在主句表示的過(guò)去的動(dòng)作之前。 例如: He said that he had known her well. 他說(shuō)他很熟悉她。 I thought I had sent the letter a week before. 我認(rèn)為我一星期前就把信寄出去了。 (6) 狀語(yǔ)從句:在過(guò)去不同時(shí)間發(fā)生的兩個(gè)動(dòng)作中,發(fā)生在前,用過(guò)去完成時(shí);發(fā)生在后,用一般
