The document discusses the passive voice and its uses. It begins by explaining that passive voice is used when the focus is on the action rather than who or what is performing the action. It provides examples of sentences in the passive voice. It then outlines the form of the passive voice, noting that the subject is followed by a form of "to be" and the past participle. It notes how active sentences are transformed into passive, with the object becoming the subject and the subject becoming an object or being dropped. Finally, it discusses how sentences with two objects are changed in the passive, with one object becoming the subject.
