Present Perfect Tense

Identification of the Tense: - The event has surely completed.

For example:

1. Ravi has gone to school.
2. They have played football.
3. He has not studied.
4. Have they lived here?

There is completeness and surety in all of the above given sentences.

Usage:- In Present Perfect tense we usually use 

(i) Third form of the verb + have (with plural and I)/has (if the subject is singular).

Explanation:-

In first sentence " Rajiv has gone to school."
"Ravi" being a singular noun is carrying has along with third form of the verb "gone."

In second sentence " They have played football"
"They" being a plural pronoun is carrying have along with third form of the verb "played."

In third sentence "He has not studied."
Being a negative sentence with sigular pronoun has  is followed by third form "studied", of the verb.

In fourth sentece "Have they lived here?"
It is an interrogative sentence haveing plural pronoun thus preceeding have to the pronoun followed by third form of the verb "lived".
