About Active and Passive Voice
Active voice presents the doer as the subject, while passive voice presents the receiver of the action and uses an appropriate form of “be” with the past participle. Questions cover tense changes, modal verbs, omitted agents and sentences that cannot be passivized because they lack a suitable object.
