How to form present perfect

To build Present Perfect we use the auxiliary verb have/has and the past participle of the main verb (its third form):

have/has + past participle

Positive and negative
I
you
we
they

have

haven't (have not)

 played
started
worked		 regular verbs
he
she
it

has 

hasn't (has not)

 done
been
lost
gone		 irregular verbs

Pay attention

We often use the short form of have and has — 've and 's.

I've had breakfast.

He's gone. 

They've lied.

Do not confuse he is / she is / it is and he has / she has / it has, although they have the same short form: he's / she's / it's.

want — wanted — wanted

finish — finished — finished
