This document discusses passive voice in English. Passive voice constructions use the verb "to be" followed by the past participle of the main verb. The subject of a passive sentence is the recipient of the action rather than the performer. Several examples are provided to illustrate how to change active voice sentences into passive voice, including changing the subject to the object of the active sentence and using appropriate forms of "to be" and the past participle verb. The tense does not change in passive transformations.
