USE OF PRESENT PERFECT

How do we make the Present Perfect Tense?

The structure of the present perfect tense is:
subject + auxiliary verb + main verb
    have   past participle
Here are some examples of the present perfect tense:
  subject auxiliary verb   main verb  
+ I have   seen ET.
+ You have   eaten mine.
- She has not been to Rome.
- We have not played football.
? Have you   finished?  
? Have they   done it?

He has

The car has
He's
She's
It's
John's
