This is my work on Intermediate Grammar Project from University of California.

Present Perfect

This tense is formed by have/has + the past participle.^[1]

The present perfect is used to indicate a link between the present and the past. The time of the action is before now but not specified, and we are often more interested in the result than in the action itself.^[2]

Some examples extracted from ef website: ^[2]

• Actions started in the past and continuing in the present:

1. They haven't lived here for years.
2. She has worked in the bank for five years.
3. We have had the same car for ten years.
4. Have you played the piano since you were a child?

• When the time period referred to has not finished:

1. I have worked hard this week.
2. It has rained a lot this year.
3. We haven't seen her today.

• Actions repeated in an unspecified period between the past and now:

1. They have seen that film six times
2. It has happened several times already.
3. She has visited them frequently.
4. We have eaten at that restaurant many times.

• Actions completed in the very recent past (with just):

1. Have you just finished work?
2. I have just eaten.
3. We have just seen her.
4. Has he just left?

• When the precise time of the action is not important or not know:

1. Someone has eaten my soup!
2. Have you seen 'Gone with the Wind'?
3. She's studied Japanese, Russian, and English.
