表示动作从过去开始一直延续到现在，可能刚刚停止，也可能仍然在进行。

1）-- Sorry, I’m late. Have you been waiting long?

3) The man started working in the field half an hour ago. He is still working now. 4) The boy started having dinner five minutes ago. He is still having dinner now. 3、注意

现在完成进行时多用持续性动词，如do, live, learn, lie, stay, wait, stand, study等， 常和all the time, this week, this month, all night, all the morning, recently等表示现在之前这一段时间的状语以及since和 for引导的时间状语或从句连用。 e.g. He has been watching television all day.

I have been learning English for three years.

She’s been playing tennis since she was eight.

This whole week, he has been training some new employees.

He has been smoking too much recently.

三、现在完成时和现在完成进行时的比较

1已经完成的动作调动作的持续性，强调“一直”，往往表示动作仍未结束。

I have been reading this novel. 我一直在读这本小说。（书不一定看完） I have read two novels. 我已读过两本小说。（动作已完成）

I have been writing letters. 我一直都在写信。

I have written three letters. 我已经写完三封信了。

2、有些动词如study, work, live用两种时态都可以，意思差别不大。

I have lived here since 1990. / I have been living here since 1990.

They have studied the problem for quite some time. / They have been studying the problem for quite some time.

3、有些动词动词本身表示一种持续的状态，一般不用现在完成进行时，如be, know, love, remember, understand, see, like, last。

I’ve known him for many years.

They have not seen each other for a long time.

The war has lasted for a long time.
