Present Perfect
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.[1]
This tense is formed by have/has + the past participle.[2]

- They haven't lived here for years.
- She has worked in the bank for five years.

- When the time period referred to has not finished: [1]
- I have worked hard this week.
- It has rained a lot this year.
- We haven't seen her today.
- Actions repeated in an unspecified period between the past and now: [1]
