The Present Perfect Continuous

Present Perfect Continuous Form:

How good are you at the Present Perfect Continuous tense? It's not a very common tense, and often it's not taught in classes, but we do use it sometimes and it's very good to know how to make it, and to recognise it when other people use it.
Luckily, it's very easy to make. Here's the positive (it's the present perfect of 'be' + verb -ing):
Positive Positive Short Form
I have been walking I've been walking
you have been running you've been running
he has been cooking he's been cooking
she has been swimming she's been swimming
it has been raining it's been raining
we have been studying we've been studying
they have been sleeping they've been sleeping


To make the negative, just add 'not':
Negative Negative Short Form
I have not been walking I haven't been walking
you have not been running you haven't been running
he has not been cooking he hasn't been cooking
she has not been swimming she hasn't been swimming
it has not been raining it hasn't been raining
we have not been studying we haven't been studying
they have not been sleeping they haven't been sleeping


Can you guess how to make the question form of the present perfect continuous? It's not very difficult - just put 'have' or 'has' before the subject:

'Yes / No' Questions
have I been walking?
have you been running?
has he been cooking?
has she been swimming?
has it been raining?
have we been studying?
have they been sleeping?

For 'wh' questions put the question word first:

'Yes / No' Questions
what have I been doing?
where have you been running?
what has he been studying?
why has she been working today?
how long has it been raining?
how long have we been watching this film?

The Present Perfect Continuous Use:

(Also called The present perfect continuous Progressive)

Some people think the present perfect continuous is difficult to use, but really it's not very complicated, and it sounds very impressive when you use it correctly.
There are two main times we use this tense. Remember we can't use it with stative verbs.
1: To say how long for unfinished actions which started in the past and continue to the present. We often use this with for and since. (See the present perfect for the same use with stative verbs)
  • I’ve been living in London for two years.
  • She's been working here since 2004.
  • We've been waiting for the bus for hours.
2: Actions which have just stopped (though the whole action can be unfinished) and have a result, which we can often see, hear, or feel, in the present (focus on action). (See the present perfect for a similar use which focuses on the result of the action)
  • I’m so tired, I’ve been studying.
  • I've been running, so I'm really hot.
  • It's been raining, the pavement is wet.
  • I've been reading your book, it's very good.
