3.They___________ cleaning the classroom this afternoon. 他们忘了今天下千已扫过教室了。

时态意义：过去完成时可以表示过去某一时刻或某一动作之前完成的动作或呈现的状态。

也就是说发生在“过去的过去”。

既然过去完成时的动作发生在过去某一时间之前，那么，使用过去完成时就必须先有这样一个过去的时间。

eg．I had finished my homework before supper．我在晚饭前把作业做完了。

句中的supper既是过去某一时间，而had finished 这一动作就是在supper 之前完成的。

如果只说I had finished my homework．听者会觉得难以理解。

由此可见，过去完成时是个相对的时态，它不能离开过去的时间而独立存在。

eg．By the end of last year Henry had collected more than one thousand foreign stamps．到去年年底，亨利已经收集了一千多张外国邮票。

（过去时间是the end of last year）eg．When we got there, the football match had already started．当我们到那里时，足球比赛已经开始了。

（过去时间是when从句）eg. By the time I got outside, the bus had already left..到我出去之前，公共汽车已经离开了。

（过去的时间是by the time 从句，by the time 意思是“_________________________________”后面常根一个______________时的句子，而主句常用________________时的句子。
