The document discusses active and passive voice in Spanish. It provides an example of active voice using the sentence "Ruben broke the mirror" and the corresponding passive voice version "The mirror was broken by Ruben." It explains that to change a sentence from active to passive voice, it must contain a transitive verb, which takes an object, and the object becomes the subject. Intransitive verbs that do not take objects cannot be used in the passive voice. It also includes a chart showing how to form sentences in both the active and passive voice across several tenses.
