P.10 Comparison
Present perfect or present perfect continuous tense?
She is still reading the book.
Li Jia has been reading a
book about Stonehenge.
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 __________ (visit)
Japan twice this
month.
He _______________ (tour)
America for two months.
has visited
has been touring
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 many times _______________
(swim) in the lake?
How long ______________________ (swim) in the lake?
have you been swimming
have you swum
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?
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 already
been to Tibet.
I’ve never visited
Tibet.
Note:
We use the present perfect tense,
not the present perfect continuous
tense, with the words like always,
never, yet, already and ever.

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.
