Use
Past → Present
The Present Perfect Simple is used to describe a past action that has a result in the present:
Example One

Example Two

Example Three

Already & Yet
Already = before the expected time

A: Hello, Mrs.Smith. It's Rick. Is James there?
B: Hi, Rick. Sorry but James has already gone to bed.

Yet = until now
It is used mainly at the end of questions and negative sentences:

Has the movie started yet?

The sun hasn't set yet.

Class hasn't finished yet.
Until Now
We often use the Present Perfect Simple when we talk about a time from the past until now. The time is not finished.
Examples of Unfinished Past Times:
- my life
- today
- this week
- this year
- this month

His vehicle has stalled six times.
(in his life)

I've already had my birthday this year.
Ever & Never
When we talk about life experience, it is popular to use ever in questions:

Have you ever tried racing?

Have you ever been to Singapore?
Never = I don't have the experience.

I'm nervous because I've never flown in an airplane.

I can't believe you've never driven a sports car!
Been & Gone
For the past participle of go, English speakers use both gone and been.
Gone = the person is there now

A: Do you know where Matt is?
B: I think he's gone to the bathroom.

I am taking care of Shelly's apartment. She's gone to Hawaii.
Been = the person went, but now he or she is back

A: Do you need to go to the washroom before we go?
B: No thanks. I've already been to the washroom.
