(2)Tom lets his little sister water flowers every day.,They are made to work ten hours a day.,His little sister is let to water flowers every day by Tom.,5.含有双宾语的句子，主动句中的间接宾语或者直接宾语都可 变为被动语态中的一个主语，另一个保留不变。变为主语的若 是主动句中的直接宾语在变为间接宾语前则需加介词to或 for。 常用双宾语的动词：show/give/offer/send /bring/ lend /teach/buy。 例如： The teacher gives the pupils some advice.,
