The document defines active and passive voice and provides examples. The active voice uses direct action verbs and puts the subject at the front doing the acting. The passive voice uses "to be" forms and emphasizes what was done rather than who did it. Active voice creates shorter, more direct and forceful sentences with greater clarity. While active voice is preferable, too much can become unreadable, so balancing the two voices is important. The passive voice can be used when the actor is unknown or to focus on the receiver of the action.
