ManypeoplespeakEnglish 谓语speak的动作是由主语manypeople来执行的 被动语态表示主语是动作的承受者 即行为动作的对象 巧记为 被动 被动 主被动 例如 Englishisspokenbymanypeople 主语English是动词speak的承受者 二 一般现在时被动语态的构成 肯定 主语 is am are 过去分词 其他 by 主动语态句子的主语 否定 主语 is am are not 过去分词 其他 by 主动语态句子的主语 1 把主动语态的宾语变为被动语态的主语 三 主动语态变被动语态的方法 WeoftenusearecorderinourEnglishclass 宾语 ArecorderisoftenusedinourEnglishclass byus 主语 谓语 2 把谓语变成被动结构 be 过去分词 根据被动语态句子里的主语的人称和数 以及原来主动语态句子中动词的时态来决定be的形式 WeoftenusearecorderinourEnglishclass ArecorderisoftenusedinourEnglishclass byus 一般现在时的被动语态 3 把主动语态中的主语放在介词by之后作宾语 将主格改为宾格 如主语是人称代词 一般省略 Theymakethebikesinthefactory Thebikesaremade bythem inthefactory 4 在主动语态句中动词make have let see watch hear feel等后接动词不定式作宾语补足语 动词不定式不加to 但变成被动语态时后面的不定式都须加上to 例如 1 Thebossmakesthemworktenhoursaday 2 Tomletshislittlesisterwaterflowerseveryday Theyaremadetoworktenhoursaday HislittlesisterislettowaterflowerseverydaybyTom 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 Theteachergivesthepupilssomeadvice Thepupilsaregivensomeadvicebytheteacher 直接宾语 间接宾语 Someadviceisgiventothepupilsbytheteacher 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 Licorrectsthestudents homeworkeverymorning Thestudents homeworkiscorrectedbyMr Lieverymorning 2 Peopleplaybasketballallovertheworld Basketballisplayedbypeopleallovertheworld 主语 主语 谓语 宾语 谓语 宾语 Practice 3 Weoftenseehimhelphisclassmates Heisoftenseentohelphisclassmates 4
