This document discusses the passive voice and how to change sentences from active to passive voice. It explains that in the passive voice, the subject receives the action rather than performs it. It provides examples of changing different tenses, such as present simple, present continuous, present perfect, past simple, and future, from active to passive voice. The object of the active sentence becomes the subject of the passive sentence, and the finite verb changes to some form of "to be" plus the past participle.
