The document discusses the differences between active and passive sentences. In an active sentence, the subject performs the action on the object. In a passive sentence, the object of the active sentence becomes the subject and the subject becomes introduced with "by". Changing a sentence from active to passive voice switches the subject and object but maintains the same overall meaning.
