The document discusses the formation of the passive voice in English. It explains that in the passive voice, the focus is on the action of the verb rather than who performed the action. The passive voice is formed using the verb "to be" plus the past participle of the main verb. Examples are provided of how to form the passive voice in different tenses. The active and passive forms of several sentences are also listed for comparison.
