The subject of the passive voice usually corresponds to the direct object of the corresponding active-voice formulation (as in the above examples), but English also allows passive constructions in which the subject corresponds to an indirect object or preposition complement: We were given tickets. (subject we corresponds to the indirect object of give) Tim was operated on yesterday. (subject Tim corresponds to the complement of the preposition on) In sentences of the second type, a stranded preposition is left. This is called the prepositional passive or pseudo-passive (although the latter term can also be used with other meanings).
