Title: THE PRESENT PERFECT CONTINUOUS TENSE


1
THE PRESENT PERFECT CONTINUOUS TENSE
2
  • Revision of the Present Perfect Simple
  • Formed with the present tense of have the past
    participle I have worked, he has worked etc.
  • Use mixture of present and past. It always
    implies a strong connection with the present and
    is mainly used in conversations, letters,
    newspapers and TV and radio reports.
  • Used for past actions whose time is not definite
    I have read the instructions but I don't
    understand them. (time not given, so present
    perfect) but
  • I read the instructions last night. (time given,
    so simple past)

THE PRESENT PERFECT CONTINUOUS TENSE
  • FORM
  • This tense is formed by the present perfect of
    the verb to be (have been) the present
    participle (the -ing form of the verb)
  • I have been working We have been
    working
  • You have been working you have been working
  • He/she/it has been working they have been

    working

4
Negative I have not/ haven't been working
etc. Interrogative Have I been working?
etc. Negative interrogative Have I not/ Haven't
I been working? etc.
5
USE This tense is used for an action which began
in the past and is still continuing I-----------
--------o--------------
TS (time of speaking) I have been waiting
for an hour and he still hasn't turned up. Or
has only just finished I-------------------------
------o
TS I'm so sorry I'm late. Have you been
waiting long?

Comparison of the present perfect simple and
continuous
  • Ongoing activities
  • The present perfect continuous is used with for,
    since, How long...? and other expressions of
    duration (e.g. all day), to talk about activities
    starting in the past and still happening now. The
    activity may have been going on continuously or
    repeated several times
  • They have been producing cars here for ten years.
    (They started producing cars ten years ago. They
    are still producing cars)

7
I have been trying to ring them all day. (I
started trying to ring them this morning. I am
still trying to ring them) However, we normally
use the present perfect simple with stative verbs
(be, believe, know, hear, smell, taste, like,
etc) or for situations we consider permanent
Ken has been in London since 9 o'clock this
morning. (not has been being...) I have lived
in London all my life. (not have been
living...)
8
Finished and unfinished activities A repeated
action in the simple present perfect can
sometimes be expressed as a continuous action by
the present perfect continuous I've written six
letters since breakfast. (present perfect
simple) I've been writing letters since
breakfast. (present perfect continuous)
9
The present perfect continuous expresses an
action which is apparently uninterrupted we do
not use it when we mention the number of times a
thing has been done or the number of things that
have been done.In this case we use the present
perfect simple. I have been knocking. I don't
think anybody's in. I have knocked five times. I
don't think anybody's in.
10
There is a difference between a single action in
the present perfect simple and an action in the
present perfect continuous I've polished the
car. (the job is finished) I've been polishing
the car (this is how I've spent the last hour'.
It does not necessarily mean that the job is
completed.)
11
A single action in the present perfect continuous
continues up to the time of speaking, or nearly
up to this time He's been taking photos. (he's
probably still carrying his camera) but He has
taken photos. (this action may or may not be very
recent)
12
Negatives In the negative, the present perfect
simple focuses on the amount of time that has
passes since something happened. The present
perfect continuous focuses on the verb itself I
haven't had a holiday for two years. (The last
time was two years ago) I haven't been feeling
well recently. (this has been continuing for days)
13
Recently finished activities We can use the
present perfect continuous to talk about an
activity that has just finished. Often there is
something you can see that shows the activity has
just finished. Look the ground is wet. It has
been raining.
