He has been
She has been
It has been
John has been
The car has been
He's been
She's been
It's been
John's been
The car's been
We have been We've been
They have been They've been
Here are some examples:
  • I've been reading.
  • The car's been giving trouble.
  • We've been playing tennis for two hours.

How do we use the Present Perfect Continuous Tense?

This tense is called the present perfect continuous tense. There is usually a connection with the present or now. There are basically two uses for the present perfect continuous tense:

1. An action that has just stopped or recently stopped

We use the present perfect continuous tense to talk about an action that started in the past and stopped recently. There is usually a result now.
I'm tired because I've been running.
past present future

!!!
Recent action. Result now.
  • I'm tired [now] because I've been running.
  • Why is the grass wet [now]? Has it been raining?
  • You don't understand [now] because you haven't been listening.

2. An action continuing up to now

We use the present perfect continuous tense to talk about an action that started in the past and is continuing now. This is often used with for or since.
I have been reading for 2 hours.
past present future


Action started in past. Action is continuing now.
  • I have been reading for 2 hours. [I am still reading now.]
  • We've been studying since 9 o'clock. [We're still studying now.]
  • How long have you been learning English? [You are still learning now.]
  • We have not been smoking. [And we are not smoking now.]

For and Since with Present Perfect Continuous Tense

We often use for and since with the present perfect tense.
  • We use for to talk about a period of time - 5 minutes, 2 weeks, 6 years.
  • We use since to talk about a point in past time - 9 o'clock, 1st January, Monday.
for since
a period of time a point in past time

x
20 minutes 6.15pm
three days Monday
6 months January
4 years 1994
2 centuries 1800
a long time I left school
ever the beginning of time
etc etc
Here are some examples:
  • I have been studying for 3 hours.
  • I have been watching TV since 7pm.
  • Tara hasn't been feeling well for 2 weeks.
  • Tara hasn't been visiting us since March.
  • He has been playing football for a long time.
  • He has been living in Bangkok since he left school.
For can be used with all tenses. Since is usually used with perfect tenses only.

The present perfect continuous tense is often used (with for or since) to describe how long something has been happening up to now.

Present Perfect Continuous Timeline

For example:-
Q) How long have you been studying English?"
A) I've been studying English for four years."
Note
- You can just say "For four years."

Q) How long have you been living in Germany?
A) I've been living here since 1998.
Note - You can just say "Since 1998".
The present perfect continuous is also used to refer to an event that may or may not be finished when it's effect can be seen now.
For example:-
Look! It's been snowing.
Note
- It's not necessarily snowing now but you can see the effect (the snow on the ground).

You should also use the present perfect continuous when talking about how long you have been doing your current job or working on unfinished projects:-
For example:-
I have been working at BT for three years.
We have been exporting to China since 1999.
!Note It is always for a length of time and since a point in time
