过去完成时PPT演示.pptVIP

5. 表示意向的动词，如hope, wish, expect, think, mean, suppose等，用过去完成时表示“原本……，未能……”。 1.结果比我们想象的要好。 The result was better than what we had expected. 2. 我们期望你会来的，但是你没有来。 We had hoped that you would come, but you didnt. 试作比较： 昨天我见到王先生了．自从他离开北京我们就一直未曾见过面。 I saw Mr. Wang yesterday. We had not seen each other since he left Beijing. 自从他离开北京我们就一直未曾见过面。 We have not seen each other since he left Beijing. 过去完成时与一般过去时的区别 1. 时间状语不同．过去完成时在时间上强调“过去的过去”，而一般过去时只强调过去某一特定的时间 They had arrived at the station by ten yesterday. (说明不到１０点就在车站了） They arrived at the station at ten yesterday. (说明１０点到车站的） 2) 在没有明确的时间状语做标志时，谓语动词动作发生的时间先后须依据上下文来判断，先发生的用过去完成时，后发生的用一般过去时． ３) 当两个或两个以上的动作用and或but连接时，按时间顺序只需用一般过去时代替过去完成时；另外在引导的从句中由于这些连词本身已经表示时间的先后，因此也可以用过去时来代替过去完成时 He entered the room, turned on the light and read an evening paper.

The film had begun before we got to the cinema. 2. 过去完成时表示过去某一时间以前开始一直延续到那个时间并可能延续下去的动作。常和by或since, for引导的表时间的从句或短语连用,但必须要与一个表示过去时的动作相对照. 1. 他来我们学校之前已经在那所学校工作了三年. 2. 当Millie到达电影院的时候, 电影已经开始了半个小时了. 3. 自从他离开南京我们就一直没有见过面.
