The document discusses the passive voice in English. It explains that the passive voice is used to emphasize the action rather than the subject performing the action. It provides examples of how to form the passive voice using the auxiliary verb "to be" plus the past participle of the main verb. Examples are given for simple present, present continuous, simple past, past continuous, present perfect, and past perfect tense in both active and passive voice. General examples are also given for changing sentences from active to passive voice.
