Ⅱ. 现在完成进行时的用法
1. 表示并不是一直在不停地进行,而是在断断续续地重复的动作。
You have been saying you can succeed for five years. 五年来你一直在说你能成功。
2. 表示刚才、近来发生的动作,刚终止,不再继续下去或还将继续下去。此时一般通过上下文的语境进行判断。
My hands are dirty. I've been painting the door.
我的手很脏,我一直在漆门。
Chinese have been making paper for two thousand years. 中国造纸有2 000年了。

3. 现在完成进行时有时带有强烈的表扬或厌恶等感情色彩。
I have been wanting to meet you for a long time.
和你见面是我盼望已久的事了。
You know, you really have been making things terribly difficult for him.
你要知道,你真是太为难他啦。
4. 现在完成进行时常与表示一段时间的状语连用,如all the time, several times, this week, all night/morning, these few days, over/in the past five years, for..., since...等。

Ⅲ. 现在完成进行时与现在完成时的区别
现在完成进行时强调动作在某一时刻内一直在进行。到目前为止,该动作可能刚刚结束,也可能还在继续进行,强调进行的过程。还表示从过去到现在的一段时间反复进行的动作或存在的状态。句中常有all day(一整天), all morning(一上午), for(有……多久)和since(自……以来)等。
现在完成时表示已结束的动作,不表示动作的重复。
注意:有些动词如learn, lie(躺), live, rain, sleep, study, wait, work等本身就有持续性,其现在完成进行时和现在完成时可以互换,但前者更强调动作的持续性。
