This document discusses the active and passive voice in writing. It defines voice as the form a verb takes to indicate whether the subject performs or receives the action. The active voice has the subject performing the action, while the passive voice has the subject receiving the action. The document provides examples of sentences in both voices and recommends using the active voice whenever possible since it is more direct and forceful. It also discusses when to use the passive voice, such as when the performer is unknown or unimportant. The document explains how to identify and form passive voice sentences using forms of the verb "to be" along with the past participle of the main verb.
