The document discusses the active and passive voice. It provides examples of sentences in the active voice and how to change them to the passive voice. The key points are: 1. The active voice has the subject performing the action, while the passive voice has the subject receiving the action or it is unknown who performed the action. 2. To change a sentence from active to passive voice, the object of the active sentence becomes the subject of the passive sentence and "was/were" plus the past participle of the verb is used. 3. Examples are provided to demonstrate changing sentences like "The teacher dropped the pen" to the passive voice "The pen was dropped by the teacher."
