The document discusses the passive voice in English grammar. The passive voice is used when the focus is on the action rather than the subject performing the action. It explains that in the passive voice, the subject and object from the active voice switch places. Various verb tenses in the passive voice are also explained, showing how the verb "to be" is used along with the past participle of the main verb. Examples are provided to illustrate how sentences are rewritten from the active to the passive voice.
