The subject of the passive sentence is the object of the active sentence. The object of the passive sentence is the subject of the active sentence. If the subject is the doer in the active sentence, we will put it after the preposition BY in the passive voice and it is known as Subject Agent. ACTIVE VOICE: Peter listens a song. PASIVE VOICE: A song is listened by Peter. (S. Agent) Peter 8. We must add the verb to be conjugated in the same tense the main verb had in the active voice. The main verb of the active sentence should be in past participle tense in the passive sentence. ACTIVE VOICE: My son don't eat vegetables. (Present Simple) PASSIVE VOICE: Vegetables are eaten by my son. (P. Simple+P. Participle) 9. When the sentence has two objects, the subject of the passive voice can be the indirect object or the direct object: ACTIVE VOICE: Lola sewed Katy a beautiful dress. PASSIVE VOICE: Katy was sewn a beautiful dress by Lola.* A beautiful dress was sewn to Katy by Lola. *This form is preferred in English. 10. If the indirect object is a pronoun in the active sentence (her, me, his..), we will put it as subject form (She, I, he..) in the passive sentence. If the subject is a pronoun in the active sentence (I, we, they...), we will put it as a indirect object pronoun in the passive sentence (me, us, them..) ACTIVE VOICE: Mike sent her a love letter.
