B We also use the present perfect tense to talk about something that started in the past, and is still happening now.

C We use the present perfect tense when the exact time of an action is not clear or important. We use it with time expressions such as:
already ever for just lately never recently since yet
We use already for affirmative statements and yet for negative statements.
We use for + a period of time and since + a point in time.
D We use the present perfect tense to talk about actions that were completed only a short time ago. In this case, just is used. Pay attention to the position of just.
He has just gone out.(=He went out a few minutes ago.)
We use the present perfect tense here to tell others that he isn’t here now.
I have just heard the news.(Now I know the news.)
E We can also use the present perfect tense for repeated actions, that is, we use the present perfect tense with the time expressions once/twice/three times…
F Actions occurring in an incomplete period might be indicated by today or this morning /afternoon/evening/week/month/year/century or all day/night/week, all the time, always etc.

3)On meeting someone, you may say: I haven’t seen you for ages.(But I see you now.)
4) For a past action whose time is not definite and often has a result in the present.

5 Compare the present perfect and the present perfect continuous tense
Li Jia has read a book about Stonehenge.
Li Jia has been reading a book about Stonehenge.
In the first sentence, it means the action read isn’t still continuing, and Li Jia knows what the book is about now, but in the second sentence , it means the action read is still continuing.
c.f. I’ve cleaned the house.
I’ve been cleaning the house.
Read Point 1 on page 10.
Notes:
1)I have visited Egypt twice this month.
I have been touring Egypt for two months.
The present perfect continuous tense can’t be used with time expressions such as twice or how many times, because in this tense the action is continuous, not stopped and started again.
We can use the present perfect tense for repeated actions, and the present perfect continuous tense for non-stop actions.
2)How many times have you swum in the lake
How long have you been swimming in the lake
We usually use the present perfect tense to ask questions beginning with how many/much, and the present perfect continuous tense to ask questions beginning with how long.
3) I’ve never visited Paris.
I’ve already been to Paris.
always, never, yet, already and ever can’t be used in a continuous tense.
4)I have not been sleeping well since I returned home.
I’ve been waiting for an hour.
We can use for and since with the the present perfect continuous tense.
5)Both present perfect tense and present perfect continuous tense
An action which began in the past and is still continuing or has only just finished can, with certain verbs, be expressed by either the present perfect or present perfect continuous.Verbs which can be used in this way include expect, hope, learn, lie, live, sleep, sit, study, wait, want, rain, etc.
How long have you learnt English Or
How long have you been learning English
It has snowed for a long time.
It has been snowing for a long time.
6 A state verb or an action verb
I have had this camera for five years.(state verb)
I have taken photos of UFOs with this camera.(action verb)
I have been taking photos of UFOs with this camera.(action verb)
An action means something happening or changing. A state means something staying the same. Some examples of action verbs are do, go, and play. Some examples of state verbs are like, know and exist.
A state verb doesn’t mean an action, so it can’t be used in a continuous tense.
They’ve always had a big garden.
How long have you known each other
He’s been in hospital since his accident.
