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. 2.由“过去的过去”来判定. 过去完成时表示“过去的过去”,是指过去某一动作之前已经发生或完成的动作,即动作有先后关系,动作在前的用过去完成时,在后的用一般过去时.这种用法常出现在: ( 1 )宾语从句中 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. ( 2 )状语从句中 在时间、条件、原因、方式等状语从句中,主、从句的动作发生有先后关系,动作在前的,要用过去完成时,动作在后的要用一般过去时.如: After he had finished his homework,he went to bed. 注意:before,after 引导的时间状语从句中,由于 before 和 after 本身已表达了动作的先后关系,若主、从句表示的动作紧密相连,则主、从句都用一般过去时.如: After he closed the door,he left the classroom. (3)表示意向的动词,如hope,wish,expect,think,intend,mean,suppose等,用过去完成时表示原本…,未能… We had hoped that you would come,but you didn't. 3.根据上、下文来判定. I met Wang Tao in the street yesterday.We hadn't seen each other since he went to Beijing.
