This document provides examples and instructions for forming sentences in the passive voice in English. It explains that the passive voice is formed by making the direct object of an active sentence the subject, using a form of "to be" as the main verb, and adding the past participle of the original verb. Forming sentences in the passive voice allows the focus to be on the object of the action rather than the subject performing the action. Optional phrases with "by" can identify the subject of the corresponding active voice sentence.
