Usage:-

Generally, we use the present perfect continuous to talk about that which began in the past and is still happening in the present; the focus is on something that continues to happen, as opposed to something which happened (finished) sometime in the past. We can also use the present perfect continuous to emphasize the length of time that has passed while something is happening, or that something is only temporary. We can also use it to talk about something that has been happening lately or only finished very recently
يستخدم زمن المضارع التام المستمر للتحدث عن اشياء بدأت بالحدوث في الماضي ولكنها مازالت مستمره معنا الى وقتنا الحالي او ان هذا الزمن يستخدم عندما نريد ان نشير الى مدة طول الحدث ( كم من الوقت مر بينما الحدث يستمر بالحدوث) او اننا نستخدم هذا الزمن للتحدث حول شيء حدث مؤخرا


Note:- The present perfect continuous is very close in meaning to how we use the present perfect tense. However, there are some key differences that distinguish when and how the present perfect continuous is preferable.


1- ☆That which began in the past and continues in the present☆
حدث يحدث في الماضي ومازال مستمر بالحدوث للوقت الحالي
The present perfect continuous is often used to talk about something that began happening in the past (anytime “before now”) and which is still happening (unfinished) in the present. We usually specify the duration of time involved, especially using the prepositions “for” or “since.” Sometimes we can use different adverbials; sometimes we don’t have to specify the duration at all.

Examples:-
1- I have been living in New York City.
2- I have been living in New York City for three years.


2- ☆Emphasizing length of time☆
التوكيد على مدة الحدوث
The present perfect continuous is especially useful for putting emphasis on the length of time that has passed while something is happening. This is particularly true when the meaning of the sentence could otherwise be expressed in the present perfect simple.

Examples:-
1- They have studied for three weeks for this exam.
(present perfect)
2- They have been studying for three weeks for this exam.
(present perfect continuous)


3- ☆That which has been happening lately or finished very recently☆
شيء حصل مؤخرا او لساته انتهى
The present perfect continuous can also be used to express that which has been happening lately, but is not necessarily happening at the present moment in time.

Examples:-
1- Bill has been coming into work late a lot.
2- Don't you think Mary has been spending too much time on the computer lately?

It can also be used without an adverbial to indicate that something was happening until only recently

Example:-
1- My neighbors are angry because my dog has been barking.
