Present Perfect Tense

Present perfect tense is used to express an action beginning in the past, but the action still related in the mind of speaker with the moment of speaking.
It is used to refer to : 
·         An action or situation which began in the past and still current.
·         An action or event which took place in the past, where the exact time of the event is not specified or not clear.
·         An action or event which has just happened.

The formula of Present Perfect Tense is:
1.      Verbal
·         (+) S+ Have/has + V3 + O/C
example : She has learned to speak Spanish.
·        (-)  S + have/has + not + V3 + O/C
example : I have not changed one bit.
·        (?) Have/Has + S + V3 + O/C +?
example : Have you cleaned your room yet?
2.    Nominal
·        (+) S + Have/has + Been+ Compliment
Example : I have been to Tokyo.
·        (-) S + Have/Has + Not + Been + Compliment
Example : I have not been quite myself since the accident.
