pickedaresent被动语态英语动词有两种语态，即主动语态（ActiveVoice）和被动语态（PassiveVoice）。当主语为动作的执行者时，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。ManypeoplespeakEnglish.Englishisspokenbymanypeople.主动语态，主语people是动作speak的执行者被动语态，主语English是动作speak的承受者一、被动语态的构成被动语态是由“be+动词的过去分词”构成的。

助动词be随着主语的人称、数和时态的变化而变化。二、一般现在时的被动语态时态被动语态结构例句主动语态被动语态一般现在时am/is/are+动词过去分词Wecleantheclassroomeveryday.Theclassroomiscleanedbyuseveryday.三、主动语态变被动语态的方法We

被动语态：主语be+过去分词by+宾语即:、主变宾、宾变主,谓语动词变被动。(注:主变宾即主语变为介词by宾语)1.Theyoftencleantheirclassroomafterschool.(改为被动语态)Theirclassroom_____often______bythemafterschool.2.
