Introduction:
Any action or an event that started in the recent past and express idea of completion or occurence, without an exact time of its completion is expressed in the present perfect tense. Present perfect tense is also used for actions completed in the recent past, not very long time ago.
The present perfect tense form of a verb has two parts:
The present tense form of ‘to be’ – known as helping verb or auxillary verb
Past participle form of the main verb.
The structure of the sentence:
Affirmative sentences:-
Subject + helping verb + main verb + object
subject+ have/has + main verb (in past participle form) + object
Example: I have finished my work.
Interrogative sentences:-
Helping verb + subject + main verb + object
Have/has + subject + participle form of main verb + object
Example: Have I finished my work?
Negative sentences:-
Subject + helping verb + NOT – main verb + object
Subject + have/has NOT + participle form of main verb = object
Example: I have not finished my work.
