She had finished writing the composition by 10 :00 this morning. 1. 由时间状语来判定 　　一般说来，各种时态都有特定的时间状语。与过去完成时连用的时间状语有： 　　（ 1 ） by + 过去的时间点。 　　如： I had finished reading the novel by nine o'clock last night. 　　（ 2 ） by the end of + 过去的时间点。 　　如： We had learned over two thousand English words by the end of last term. 　　（ 3 ） before + 过去的时间点。 　　如： They had planted six hundred trees before last Wednesday. （4）当宾语从句的主句为一般过去时，且从句的动作先于主句的动作时，从句要用过去完成时。在told, said, knew, heard, thought等动词后的宾语从句。如： 　　She said that she had seen the film before. (5)主句是when，after加过去时态句子 When I got to the station, the train had already left. 　　After he had finished his homework, he went to bed. 过去完成时态的用法： 1、表示过去的过去，通常由by引导的短语做时间状语或者由by / when / before引导的从句做时间状语从句 ① By the end of last year, I had learned about one thousand English words. ② By the time he was twenty, he had won about ten medals. ③ When I got there, they had already left. ④ They had already had breakfast before they arrived at the hotel. ⑤He said that he had never seen such a beautiful bird before. 2、常用在宾语从句中 ① He told me he had already finished his homework. ② I realized he had fooled me again. 3、体现在上下文中 I didn’t go to the movies yesterday because I had seen it twice. 四、过去完成时与现在完成时的区别 　　现在完成时表示的动作发生在过去，但侧重对现在产生的结果或造成的影响，与现在有关，其结构为“助动词 have (has) + 过去分词”；过去完成时则是一个相对的时态，它所表示的动作不仅发生在过去，更强调“过去的过去”，只有和过去某时或某动作相比较时，才用到它。 By the time she got outside, the bus had already left. 她出去的时候,公共汽车已经开走了. by the time 意思是 “到…的时候”, 相当于 when , 后接过去时的句子 时, 主语的谓语动词用过去完成时态.
