【注意】

1.含有双宾语的主动句变为被动句时，把代表人的间接宾语变为被动句的主语，把直接宾语变为被动句的宾语；若把主动句的直接宾语变为被动句的主语，间接宾语前必须加介词for或to。

e.g.Myauntgavemeabookonmybirthday.

Iwasgivenabookonmybirthdaybymyaunt.

Abookwasgiventomeonmybirthdaybymyaunt.

我的姑妈在我生日时送给我一本书。

;2.当主动句中的谓语动词是feel,hear,make,see,watch,lookat,notice等时，其后作宾语补足语的动词不定式要省略to，但变为被动句时，要补上动词不定式符号to。

WeheardMarysingasongattheparty.我们听见玛丽在聚会上唱歌。

Marywasheardtosingasongatthepartybyus.

3.含有动词短语的被动句，其短语中的介词或副词不能丢掉。

Atallbuildingwasputupinmyhometown.我的家乡建起了一座高楼。;4a;Shouldteenagers________(ask)tomoveoutwhentheystartworking?InmanyWesterncountries,teenagers__________(allow)tomoveoutateighteen.Theirparentsbelievethattheyshouldbeeducatedtotakecareofthemselvesfromayoungage.Thisway,whenthey______(start)workingtheycanmanagetheirownlives.However,inmostAsiansocieties,itisnotcommonforteenagersto________(move)out.Chineseparentsbelievethatitisbetterforchildrentolivewithparentswhocan________(take)careofthem.Buttheyoungshouldthenlookaftertheirparentsastheygetolder.ThatiswhymanyChineseadults__________(continue)tolivewiththeirparents.;A:Membersshouldbeallowedtousedictionarie
