PRESENT PERFECT CONTINUOUS​

The present perfect continuous is used to refer to an unspecified time between 'before now' and 'now'. The speaker is thinking about something that started but perhaps did not finish in that period of time. He/she is interested in the process as well as the result, and this process may still be going on, or may have just finished.

ACTIONS THAT STARTED IN THE PAST AND CONTINUE IN THE PRESENT
She has been waiting for you all day (= and she's still waiting now).
I've been working on this report since eight o'clock this morning (= and I still haven't finished it).
They have been travelling since last October (= and they're not home yet).

ACTIONS THAT HAVE JUST FINISHED, BUT WE ARE INTERESTED IN THE RESULTS
She has been cooking since last night (= and the food on the table looks delicious).
It's been raining (= and the streets are still wet).
Someone's been eating my chips (= half of them have gone).

FORMING THE PRESENT PERFECT CONTINUOUS
The present perfect continuous is made up of two elements: the present perfect of the verb 'to be' (have/has been), and the present participle of the main verb (base+ing)

Subject	has/have been	base+ing
She	has been	swimming

Affirmative: She has been / She's been running.
Negative: She hasn't been running.
Interrogative : Has she been running?
Interrogative negative: Hasn't she been running?

Affirmative	Negative	Interrogative
I have been living	I haven't been living	Have I been living?
You have been living	You haven't been living	Have you been living?
He, she, it has been living	He hasn't been living	Has she been living?
We have been living	We haven't been living	Have we been living?
You have been living	You haven't been living	Have you been living?
They have been living	They haven't been living	Have they been living?

VERBS WITHOUT CONTINUOUS FORMS
With verbs not normally used in the continuous form, use the simple present perfect instead (verbs such as: know, hate, hear, understand, want).
I've wanted to visit China for years.
She's known Robert since she was a child.
I've hated that music since I first heard it.
I've heard a lot about you recently.
We've understood everything.
