the floor.4.I told her to return the book in time.She _ _ to return the book in time.The ticket was found was told3.We found the ticket on the floor.5.Last year we built a library in ourschool.A library _ _ in our school last year.was built5.The teacher asked Tom to turn on the computer.Tom _ _ to turn on the computer.6.In this factory women do most of the work.Most of the work _ _ by women in this factory.was asked is done被动语态强调“宾”，用 be加上“过去分”。“be”要随着主语变，人称时态要弄准。“行为对象”作主语，逻辑主语“by”来引。原句若是双宾语，一变“主”来一保“宾”。“间宾”要把主语变，原来“直宾”还是“宾”。“直宾”要把主语变，“间宾”前加“to”最称心。唯有原“宾”是“复合”，只有变宾要当心。原句“宾补”变“主补”，位置不必挪寸分。情态动词变“被动”，情态加be加过分。如若“情态”后带to，变后有to才弄准。“短语动词”变“被动”，相当“及物”莫疑心。不过其后“介”或“副”，变后还得要承认。课堂练习课堂练习（一）改写句子（一）改写句子1.We
