是否有一个明确的时间点作对比,或者此时间点从上下文中可以推测出来.例如：1'I have been cleaning the room all the morning.
2'I had been cleaning the room all the morning when she came.
此处,when she come 就相当于一个时间点.

had been doing与have been doing都是过去正在进行时。
只不过前者用在虚拟语气中
而后者用于现实语句中。
比如：what have you doing when I called you yesterday？
回答是：I have been doing my homework.
如果问题是：Have you finished you...
