The document discusses the form and use of the passive voice in sentences. It explains that in the passive voice: 1) The object of the active sentence becomes the subject of the passive sentence. 2) The verb "to be" is used, keeping the same tense as the main verb in the active sentence. 3) The subject of the active sentence becomes the object of the passive sentence, and is sometimes dropped.
