ask for information

[adel87]

dear in the book of grammar in use
they said
We use the present perfect continuous for an activity that has recently stopped or just stopped. There is a
connection with now

When we talk about a period of time that continues from the past until now, we use the present perfect
(have been/have traveled etc.). Here, Dave and Jane are talking about the places Jane has visited in her life
(which is a period that continues until now).

so this period continuous until now

so what is the difference between the present perfect continuous and present perfect simple

so what is the difference between the present perfect continuous and present perfect simple
thank you

The present perfect continuous is used:

* for continuous actions (still happening now) especially when we ask how long they have lasted, and answer with for/since.
How long have you been working here? (you work here now)
I´ve been learning to drive for two years. (I’m still learning)

* for continuous actions which have recently finished.
I´ve been shopping all morning. (I’ve just finished)

The present perfect simple is used:

* with how long/for/since for verbs not normally used in continuous forms (be, have, know, like, etc)
I´ve known her since I was a child.

* for completed actions where no time is given.
We´ve bought a new house. I´ve cut my finger.

* with ever, already, yet, just.

* when we say “how many” or “how many times”.
I´ve read two books this morning.

* with superlatives.
It was the best meal I’ve ever had.

Sometimes both forms are possible (with a difference in meaning)

The present perfect continuous emphasizes the activity itself and its duration.
I´ve been cleaning the house. (so I´m exhausted)

The present perfect simple emphasizes that the action is completed, and the result.
I´ve cleaned the house. (so it´s really clean now)

Note: live and work (+ for/since) can be used with both tenses with the same meaning.
I´ve been working here for ages. I´ve worked here for ages.
