The Present Perfect Continuous is
used to refer to an action started in the past which continues today.
ex : I have been learning English since September.
(I started in September and I continue to
take lessons today.)
The Present Perfect Simple is used to
refer to the finished part of a continuous action.
ex : So far in my English course I have learnt new vocabulary.
I have revised some grammar rules.
(My English course is not finished, but I have
finished some of the lessons)
The Present Perfect is used to refer to actions which take
place in an unfinished time period up to now.
Example
: Today, it is now 2 p.m.
At 9 o'clock this morning you started
revising your English.
Today is not finished, so you can
say "I have been revising my English since 9 o'clock."
(You are still revising, so the
continuous form is used.)
You have done part of the
revision work, which is not finished, so at 2 p.m. you can say:
"So far today, I have
revised tenses and irregular verbs."
(You do not mention any
specific time; you refer to today which is not finished.)
N.B. If you refer now
(2 pm) to
the morning, for example, which is finished, you must use
the Past Simple.
ex : This morning I revised tenses and irregular verbs.
