高二英语上学期6Unit17 Laughter过去完成进行时学案北师大版

过去完成进行时过去完成进行时表示动作在过去的某一时间之前开始，一直延续到这一时间。过去完成进行时的构成为“had been + 现在分词”。和过去完成时一样，过去完成进行时也必须以某一特定的过去时间为前提。如：He had been living here before he went to Shanghai.他去上海之前，一直住在这里。使用过去完成进行时时，应注意和其它时态的区别：1. 过去完成进行时与过去完成时过去完成进行时强调动作在过去某一特定时间之前开始，到这一时间仍在进行；而过去完成时则强调动作在过去某一动作或时间之前已经完成。如：I had been waiting in the room for half an hour before she called me in.她叫我进去之前我已经在房间里等了半个小时。（一直在等）He had already had the breakfast before we came.我们来之前他已经吃过早餐了。（动作已经结束）2. 过去完成进行时与过去进行时过去完成进行时强调动作在过去某一时刻之前一直在持续；而过去进行时强调的是在过去某一时刻正在进行。如：Last night I had been reading a novel when the bell rang. 昨天晚上铃响之前，我一直在读一本小说。（一直在读）Last night I was reading a novel when the bell rang.昨天晚上铃响时，我正在读一本小说。（当时正在读）3. 过去完成进行时与现在完成进行时过去完成进行时是以“过去”某一事件为前提；而现在完成进行时是以“现在”为前提的。如：She had been waiting for you when I met her.我遇见她的时候，她还在等你。（直到那时）She has been waiting for you since you left.你离开以后，她一直在等你。（直到现在）即学即练 从A、B、C、D四个选项中，选出可以填入空白处的最佳选项。1.
