The present perfect is formed from the present tense of the verb have and the past participle of a verb:
How to use
We use the present perfect tense:
for something that started in the past and continues in the present:
They’ve been married for ten years.
He has lived in Liverpool all his life.
for something we have done several times in the past and continue to do:
He has played the guitar ever since He was a teenager.
I have written five books and I am working on another one.
They have been watching that programme every month.
We often use a clause with since to show when something started in the past:
She has been staying with us since last month.
They have worked here since They left school.
They have been watching that programme every week since it started.
when we are talking about our experience up to the present:
Note: We often use the adverb ever to talk about experience up to the present:
her last birthday was the worst day she have ever had.
Note: and we use never for the negative form:
has he ever met Sara?
Yes, but he has never met her husband.
for something that happened in the past but is important at the time of speaking:
she can’t get in the house. she has lost her keys.
Linda isn’t at home. I think he has gone bookshop.
I’m tired out. I’ve been working all day.
