Present perfect Tense

The present perfect is a grammatical combination of the present tense and the perfect aspect, used to express a past event that has present consequences.

 The Pattern :
1. Affirmative Form
S + have/has + V3
Example :Justin has gone

2. Negative Form
S + have/has  not+ V3
Example :It hasn’t worked

3. Interrogative Form
Have/has + S + V3 + ?
Example :Have you read the book yet?
