The present perfect simple is HAVE / HAS + PAST PARTICIPLE. The past participle often ends in -ED (finished / decided / lived etc), but many important verbs are irregular (lost / been / written etc).
When we use the present perfect there is always a connection with now. The action in the past has a reuslt now:
He told me his name but I have forgotten it. (I can`t remember it now)
Is Sally here? No, she is gone out (she is out now).
We often use the present perfect to give new information or to announce a recent happening:
The police have arrested two men.
You can use the present perfect with JUST, ALREADY, and YET
JUST= a short time ago
Would you like something to eat? " No, thanks, I have just had lunch"
We use ALREADY to say that something happened sooner than expected
What time is Mark leaving? He`s already gone
YET= "until now" and shows that the speaker is expecting something to happen. Use YET only in questions and negative sentences.
I have written the letter but I haven`t posted it yet.
