6、lish song by us.他被我们要求唱一首英语歌。2带双宾语的谓语动词变为被动语态谓语动词带双宾语时，既可以将间接宾语转化成主语，也可接直接宾语转化成主语。若将间接宾语转化成主语，则保留直接宾语；若将直接宾语转化成主语则保留间接宾语，且在被保留的间接宾语前加上介词to 或 for 。e.g.She gave me a book. (变为被动语态) I was given a book. (间接宾语me改为主语 )A book was given to me. (育接宾语 a book 改为主语 )3短语动词变为被动语态许多由不及物动词构成的短语动词，相当于及物动词，可以有宾语，也可以有
7、被动语态。注意： 短语动词是一个不可分割的整体， 在变为被动语态时， 不可丢掉构成短语动词的介词或副词。e.g.We should speak to old men politely. (变为被动语态) Old men should be spoken to politely. (to不可省略 )4带复合宾语的动词变为被动语态宾语加上宾语补足语一起构成复合宾语。变被动语态时， 只把宾语变为被动句主语，宾语补足语保留在原处，成为主语补足语。e.g.I heard Jane playing the piano in her room.(变为被动语态 ) Jane was heard playing
8、 the piano in her room.5被动语态后动词形式的选择主动句中在感官动词see 、hear 、 watch 、 feel 、 notice等使役动词 ,也称为感官动词，let 、 make、 here 等动词后跟省略to 的不定式，变为被动句时，应加上不定式符号to 。e.g.He makes the girl stay at home.(改为被动结构) 。2欢迎下载精品文档The girl is made to stay at home.Last Sunday we heard them sing Peking Opera in the theatre.( 改为同义句 )
9、They were heard to sing Peking Opera in that theatre last Sunday.四句话：主语变成宾语；宾语变成主语；动词一分为二；时态体现在be 动词上。（四）被动语态的一些特殊的运用形式1主动结构表被动意义（1） open、 lock 、 write 、read 、sell、clean 、wash、cut 、burn 、drive等词作不及物动词时，它们的主语为物，可用主动语态表被动意义。e.g.This kind of pen writes very smoothly.这种笔写起来很流畅。This kind of shirt sells w
10、ell here.这种样式的衬衫在这很好卖。（ 2） look 、 sound 、taste 、smell 等系动词主动结构表被动意义。e.g.Uniforms look ugly on us.我们穿着制服很难看。Mooncakes taste delicious.月饼吃起来很好。（ 3） be worth doing 中， doing 表被动意义。e.g.This book is worth reading.这本书值得一读。（4） want/ need/ require doing 相当于 want/ need/require to be done 。 to be done表不定式的被动结构
11、。e.g.My bike needs repairing.= My bike needs to be repaired.我的自行车需要修理。（五）不用被动语态的情况1主动句的宾语是each other或反身代词时，不能用于被动语态。e.g.The man introduced himself as Mr. White. (主动语态 )那个人自我介绍说他是怀特先生。Himself was introduced as Mr. White.(误 )They help each other study English. (主动语态 )他们互相帮助学习英语。Each other is helped st
12、udy English. (误 )2当主动句的谓语动词是表状态的及物动词时，不能用于被动语态。e.g.We will have a meeting.我们将开一个会。3主动语态的宾语是动词不定式或-ing形式时，不能用作被动语态的主语。e.g.My brother enjoys watching TV.He asked to have a try.他请求试一次。注意：解答被动语态题目时，首先要判断主语和动作的关系，如果主语是动作的执行者，则用主动语态；如果主语是动作的承受者，则用被动语态。3欢迎下载精品文档欢迎您的下载，资料仅供参考！致力为企业和个人提供合同协议，策划案计划书， 学习资料等等打造全网一站式需求。4欢迎下载
