in the past and are still continuing.

Present perfect or present perfect
continuous tense?
Li Jia has been reading a
book about Stonehenge.
She is still reading the book.
Li Jia has read a book
about Stonehenge.
She finished reading the book.
She knows the content of the book now.
Note:
We use the present perfect tense to
talk about an action completed in the
recent past, and the present prefect
continuous tense for an action that
started in the past and is still
happening.
She __________
has visited (visit)
Japan twice this month.
He _______________
has been touring (tour)
America for two months.
Note: 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.
How long ______________________
have you been swimming
(swim) in the lake?
How many times
_______________
have you swum
(swim) in the lake?
Note: 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.
A state verb or an action verb?
1)She has had the pen for 2 years.
state verb
2)She has written many compositions
with this pen.
action verb
3)She has been writing compositions
with this pen.
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.
Note: We can use either a state verb or
an action with the present perfect tense,
but we usually can only use an action
verb with the present perfect
continuous tense. 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.
I’ve never visited Tibet.
I’ve already
been to Tibet.
Note:
We use the present perfect tense,
not the present perfect continuous
tense, with the words like always,
never, yet, already and ever.
How long have you been
learning English?
How long have you
learnt English?
It has rained for It has been raining
a long time.
for a long time.
Note: 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, snow, etc.
