The document discusses active and passive voice in sentences. Active voice is when the subject performs the action, while passive voice is when the subject receives the action. To change a sentence from active to passive voice, the subject and object are interchanged, the verb is changed to the passive form, and "by" is added before the doer of the action. Personal pronouns also sometimes change form in passive constructions.
