(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.,The pupils are given some advice by the teacher.,直接宾语,间接宾语,Some advice is given to the pupils by the teacher.,歌诀是： 宾变主，主变宾，by短语后面跟。 谓语动词变被动，be后“过分”来使用。,把下列句子变为含被动语态的句子：,1.Mr. Li corrects the students homework every morning.,The students homework is corrected by Mr. Li every morning.,2.People play basketball all over the world.,Basketball is played by people all over the world.,主语,主语,谓语,宾语,谓语,宾语,Practice,3.
