How do we make the Present Perfect Continuous Tense?
The structure of the Present Perfect Continuous tense is:
|subject||+||auxiliary have||+||auxiliary be||+||main verb|
|conjugated in Present Simple||past participle|
|have, has||been||present participle|
The first auxiliary (have) is conjugated in the Present Simple: have, has
The second auxiliary (be) is invariable in past participle form: been
The main verb is invariable in present participle form: -ing
For negative sentences we insert not after the first auxiliary verb.
For question sentences, we exchange the subject and first auxiliary verb.
Look at these example sentences with the Present Perfect Continuous tense:
|subject||auxiliary verb||auxiliary verb||main verb|
|+||I||have||been||waiting||for one hour.|
Contraction with Present Perfect Continuous
When we use the Present Perfect Continuous tense in speaking, we often contract the subject and the first auxiliary verb. 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
The car's been
|We have been||We've been|
|They have been||They've been|
- I've been reading.
- Jenny's been helping us recently.
In negative sentences, we may contract the first auxiliary verb and "not":
- I haven't been playing tennis.
- It hasn't been snowing.
