•  We use the present perfect continuous (have/has + been + ing) for unfinished actions which started in the past and continue up to now. It often answers the question How long …?
– It‘s been raining all afternoon.
– Scientists have been investigating climate change.
– How long have you been working here?

• We use the present perfect simple (have/has + past participle) for completed actions which happened at some point before now and still have an influence on the present. We don’t know or aren’t focusing on exactly when the action happened.
– It‘s stopped raining.
– Have you seen the weather forecast?

• There is sometimes little difference between the present perfect simple and continuous. The choice is often about how we see the action.
– The weather’s been improving. (We see this as something in process. )
– The weather‘s improved. (We see this as a finished state.)

We generally don’t use the present perfect continuous with verbs such as be, have, and know.
