In passive voice of perfect present tense of affirmative sentence, we use auxiliary verb have/ has with 'been' and past participle that is third form of verb. In this topic, we shall discuss the formation and changing active to passive voice of perfect present tense.
Passive Voice of Perfect Present Tense- Formation
In this, we use helping verb according to the subject that is-
- If subject of passive voice is first person, singular or plural number that is ‘I’ and ‘we’, we use helping verb ‘have’.
- For subject of second person singular or plural number that is ‘you’, we use helping verb ‘have’.
- If subject is third person singular number that is ‘he’, ‘she’, ‘it’ or any other singular number, we use helping verb ‘has’.
- For third person plural number that is ‘they’ or any other plural number, we use helping verb ‘have’.
It means, we should use 'has' for only when subject is third person and singular number. Except third person, singular; we should use have.
In passive voice of perfect present tense– positive, negative, interrogative and negative interrogative, we use past participle (third form) of verb.
Keep in mind that we should arrange the sentence in the following form-
- Active sentence- subject + have/ has + past participle of verb + object
- Passive sentence- object of the active sentence + have/ has + been + past participle ( third form ) of verb + by + subject of the active sentence

Now we shall take an example of prefect present tense and transform it into passive voice.
Have a look–
Active: She has drawn a picture today. (draw – base form)
For this, first you should learn the formation of perfect present tense.
Above sentence is in the form-
- Subject + has + past participle of verb + object + remaining word
Passive: A picture has been drawn by her today. (drawn- past participle of draw)
Passive voice of this sentence is in the form-
- Object in active + has + been + past participle of ‘draw’+ by + subject in active + remaining word.
In above sentence, we can see the changes in the transformation of active to passive voice as:
- Object of active form (picture) became subject.
