1. 构成形式：has\have been doing 2. 用法

1) 叙述某一动作从过去开始一直继续到现在仍在继续之中或刚刚停止。经常与for, since, all morning/day/week用在一起。

You have been studying for four straight hours. Why don’t you take a break? The telephone has been ringing for almost a minute. Why doesn’t someone answer it? 2) 叙述“最近”一直从事的工作或活动。

lately, recently What’s the matter? Your eyes are red and puffy. Have you been crying? 你是不是一直在哭? 3) 表示重复动作。有时现在完成进行时所表示的动作并不是在一直不停地进行, 而是在断断续续地重复。

I have been knocking. I don’t think anybody’s in.

我一直在敲门, 我想没人在里面。

You’ve been saying you can succeed for five years.

5年来你一直在说你能成功。

区别：现在完成进行时与现在完成时的区别

现在完成时表示结果, 其动作发生在过去，但对现在有影响; 而且现在完成时也可表示动作的持续。而现在完成时表示比较长久的动作和状态, 而现在完成进行时表示较短暂的动作和状态,

而且强调持续性或未暂停性。

He hasn’t worked for years.

他多年来一直没有工作。

I haven’t been working very well recently.

我最近工作不太顺利。
