38、hat I had met him.第二十二页，本课件共有33页3、一般过去时与过去完成时的比较 两个或两个以上相继发生的动作，用and或but按动作发生的先后顺序连接，此时要用一般过去时，而不用过去完成时。过去完成时则强调主语在过去某一时刻回顾更早的动作。具体来说，当我们在谈论过去某一事件时，想到了在这之前已发生的某事，这时用过去完成时态。例如：He opened the door and entered,but found nobody.He served in the army for ten years;then retired and married.His children are

39、 now at school.第二十三页，本课件共有33页He He had served in the airforce for ten years before he died in the jet-crash incident.I realized that we had methad met before.I heardheard voices and voices and realizedrealized that there were several people in the next room.I saw empty glasses and cigar butts on the

40、 table and realizedrealized that someone had been in the room.在表示两个相继发生的动作时，用过去完成时可以表示在一个动作完成以后，另一个动作才开始发生，从而使得两个动作相互独立，彼此脱离开来。用一般过去时，则可能表示一个动作“导致”另一个动作，或两个动作之间有一种因果关系。第二十四页，本课件共有33页When I had opened all the windows,I sat down and had a cup of tea.When I opened the window,the cat jumped out.When I h
