Tom说他借了这本书两周了。 Tom said he had borrowed the book for 2 weeks. ;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：;过去完成时与现在完成时的区别;过去完成时与一般过去时的区别;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.
