The document discusses the passive voice in English. It notes that the passive voice is used to place more emphasis on the object of an action rather than the person performing the action. The passive voice is generally used in written registers like scientific articles, technical documents, newspapers, and official documents. It then provides examples of transforming sentences from the active to the passive voice for different tenses, including the present simple, past simple, present perfect, past perfect simple, future with will, future with going to, and modal verbs.
