The document discusses the formation and use of the passive voice in English. It explains that in the passive voice, the subject receives the action rather than performs it. It provides rules for forming sentences in the passive voice in the present, past, future, and present perfect tenses by using various forms of the verb "to be" plus the past participle of the main verb. Examples are given to illustrate active and passive voice equivalents.
