四、特殊的被动语态
含有双宾语的被动语态
含有双宾语的主动句变被动句时,可以将其中
任何一个宾语变为被动结构的主语。一般是把
主动结构中指人的间接宾语变为被动语态的主
语,这样句子显得自然;若指物的间接宾语变为
被动语态的主语,间接宾语前要加介词to,for
复合宾语的被动语态
若主动句为“主语十谓语十宾语十宾补”这种复
合宾语结构时,则只能将宾语变为被动结构的
主语,宾补变成被动结构的主语补足语
eg: We call him Xiao wang.我们叫他小王。
He is called Xiao wang.他叫小王
注意:若主动语态中的宾补是省略to的不定
式,变为被动语态时需把to补上
eg: They heard her sing a song at the party
She was heard to sing a song at the party.在晚
会上他们听她唱了一首歌
