A pen was bought by Raju yesterday.

Structure ↴

Subject + was/were + past participle form of the main verb + preposition + Object

We Should Remember ↴

• To change the voice from active to passive, at first the subject, object and verb of a sentence must be identified.

• Then, the tense of the verb must be noted, because to transform the voice from active to passive, the necessary form of the 'be' verb should be used. It is succeeded by the past participle form of the main verb.
