复习动词时态：现在完成进行时
现在完成进行时表示动作从过去某一时间一直持续到现在或离现在不远的时间，其动作是否持续下去，则由上下文决定。
(1)叙述某一动作从过去开始，一直持续到现在，仍在继续之中或刚刚停止。常与for,since, allmorning/day/week等状语连用。
The telephone has been ringing for almost a minute. Why doesn't someoneanswer it?
(2)表示重复的动作。有时现在完成进行时表示的动作并不是一直不停地进行，而是在断断续续的重复。
—We've spent too much money recently.
—Well,it isn't surprising. Our friends and relatives have been comingaround all the time.
(3)表示“刚才、近来”发生的动作，一般不再继续，此时一般通过上下文语境来判断。
She has been sweeping the street allday. She is too tired.
(4)带有浓重的感情色彩，强调持续了“那么久”或做得“那么辛苦”。
Oh,you've come at last! I have been waiting for you for two long hours.
