现在完成进行时表示动作从某一时间开始,一直持续到现在,或者刚刚终止,或者可能仍然要继续下去。这个时态多用持续性动词,如live, learn, lie, stay, wait, stand, rest, study等,并常和all this time, this week, this month, all night, all morning, recently等状语以及since和for所引导的短语或状语从句连用。其构成为:have/has+been+动词的现在分词。

(1)I'm very tired. I've been working all morning.我很累,干了一上午的活了。

(2)How long have you been working in this company? 你在这家公司上班多长时间了?

现在完成进行时强调动作在某一时刻内一直在进行,通常表示尚未完成的动作;现在完成时则表示已完成的动作。比较:

我已经修好了洗衣机。(动作已完成)

I have been repairing the washing machine.
