ACTIVE VOICE TO PASSIVE VOICE
Intransitive sentences can't be changed to
passive voice because objects are required for
doing it.
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

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)

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.

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:
