Present Perfect Continuous Tense


How do we make the Present Perfect Continuous Tense?

Quote:
The structure of the present perfect continuous tense is:

subject + auxiliary verb + auxiliary verb + main verb (ing form)

Here are some examples of the present perfect continuous tense:

Contractions



When we use the present perfect continuous tense in speaking, we often contract the subject and the first auxiliary. We also sometimes do this in informal writing.


I have been I've been
You have been You've been
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 [now] because I've been running.

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.

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 timeó5 minutes, 2 weeks, 6 years.
We use since to talk about a point in past timeó9 o'clock, 1st January, Monday.


Here are some examples:
