The present perfect tense is very common in English.
Its form is easy to understand.
The present perfect is used to indicate a link between the present and the past. The time of the action is before now but not specified, and we are often more interested in the result than in the action itself.

Present Perfect Tense: Form

The present perfect tense always has two parts: have or
has and the past participle (“third form”) of the verb:

I         have          been / done / gone / seen, etc.
you         have         been / done / gone / seen, etc.
he, she, it         has         been / done / gone / seen, etc.
we         have         been / done / gone / seen, etc.
they         have         been / done / gone / seen, etc.

In speaking, have and has are usually contracted:

I have                         I’ve
you have                   you’ve
he / she / it has         he’s / she’s / it’s
we have                     we’ve
they have                   they’ve

The negative forms have not and has not are often
contracted, also: have not = haven’t and has not =
hasn’t. However, the contraction can also be with
have instead of with not:

I have not              I’ve not / I haven’t
you have not         you’ve not / you haven’t
he has not            he’s not / he hasn’t
she has not           she’s not / she hasn’t
it has not               it’s not / it hasn’t
we have                 we’ve not / we haven’t
they have               they’ve not / they haven’t
