Passivevoice被动语态

主动句变为被动句所遵循的4个步骤：1.把原主动句中的宾语变为被动句的主语。2.把动词变为被动形式即be+过去分词，并注意其人称和数随主语的变化，而动词的时态则保持不变。3.原主动句的主语如需要则放在by后面以它的宾格形式出现（注代词的宾格），如不需要则可省略。4.其它的成分（定语、状语）不变。不知道动作的执行/实施者强调动作的承受者出于礼貌等原因不愿说出执行/实施者何时用被动语态?

在英语中，动词有两种语态，即主动语态和被动语态。被动语态的基本结构是“be+及物动词的过去分词”，其中be有人称、数和时态的变化。一般现在时的被动语态构成助动词be＋

及物动词的过去分词助动词be有人称、时态和数的变化

当主语为动作的执行/实施者时，谓语的形式为主动语态；当主语为动作的承受者时，谓语要用被动语态。被动语态定义

介词+名词短语介词+代词宾格等宾变主，主变宾，by短语后面跟。谓语动词变被动，be后“过分”来使用。2.主动语态变为被动语态的方法第一步:将主动语态的宾语改为被动语态的主语；第二步:将主动语态的谓语改为“be+及物动词的过

去分词”结构；第三步:将主动语态的主语改为介词by的宾语，放在

谓语之后(有时可省略)。如图所示：They(主语）grow(谓语）tea(宾语）inthesoutheastofChina.被动语态:主动语态:Tea(主语）isgrown(谓语）bythem

3.一般疑问句:Be+主语+V.(过分)+(by…)?Isthenewspublishedbythegovernment?

特殊疑问句:疑问词+be+主语+V.(过分)+(by…)?Whenisthenewspublishedbythegovernment?

注意：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.

4.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，在变为间接宾语时其前则需加介词to或for。

常用双宾语的动词：show/give/offer/send/bring/lend/teach/buy

例如：Theteachergivesthestudentssomeadvice.直接宾语间接宾语→Thestudentsaregivensomeadvicebytheteacher.→Someadviceisgiventothestudentsbytheteacher.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
