Answer:

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.
