被动语态一、语态概述英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者。巧记为：主动、主动、主去动。例如：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
