not all definite time expressions may not be used with this tense.
Discuss the following questions about the present perfect tense and offer some examples:
- How is the present perfect formed? It is formed by have/has+ the past participle(V3)
- How is it used? It has 3 main functions: unfinished actions, life experiences (indefinite time) / finished actions that can be repeated, and actions finished in the recent past (past to present relevance).
- Which time words are used with it? for, since, yet, just, already, ever, and never
The present perfect tense has three main functions:
Present perfect is used to describe actions that occurred in the past, but where the exact time is not important (indefinite time). In this type of sentences, the focus is on the action. It is typically used to describe experiences.
- I have been to France.
- I have written a travel book on places of interest in France.
The second is to describe actions that occurred in the past but have a relevance (connection) to the present.
I have spoken to Karen about the meeting and we are ready to begin.
I have been to Italy and know more about the Vatican now.
The present perfect can express unfinished past when used with for or since to show duration.

I have avoided politics for as long as I remember.
I have known John for almost ten years.
- These time expressions are frequently used with the present perfect:
already, ever, never, just, yet, recently, lately, for, and since.
- Already implies the action happened before it was expected.

We have just spoken on the phone.
- Yet means the action is expected to happen or hasn’t happened. It is used at the end of the sentence.
