It's pointless learning Slang, Idioms and lots of vocabulary if we don't know the basic verb tenses, we'll revise The Present Perfect Simple



Present Perfect Simple



FORM
[has/have + past participle]



Examples:
You have seen that movie many times.
Have you seen that movie many times?
You have not seen that movie many times.

USE 1:
Unspecified Time Before Now
We use the Present Perfect to say that an action happened at an unspecified time before now. The exact time is not important.

You CANNOT use the Present Perfect with specific time expressions such as: yesterday, one year ago, last week, when I was a child, when I lived in Japan, at that moment, that day, one day, etc.

We CAN use the Present Perfect with unspecific expressions such as: ever, never, once, many times, several times, before, so far, already, yet, etc.
Examples:
Have you read the book yet?
Nobody has ever climbed that mountain.
A: Has there ever been a war in the United States?

USE 2:

Duration From the Past Until Now

Examples:
I have had a cold for two weeks.
She has been in England for six months.
Mary has loved chocolate since she was a little girl.
