被动语态(passivevoice)被动语态基本用法当句子的主语是动作的执行者时，谓语的形式是主动语态(TheActiveVoice)。当句子的主语是动作的承受者时，谓语要用被动语态(ThePassiveVoice)。被动语态由be+done/p.p(及物动词的过去分词)构成，时态通过be表现出来。主动语态变被动语态口诀：宾语提前主语变，原主变宾by后见，时态人称be关键。一般现在时态的被动语态：am/is/are+p.p一般过去时态的被动语态：was/were+p.p一般将来时态的被动语态：willbe+p.p现在进行时态的被动语态：am/is/arebeing+p.p过去进行时态的被动语态：was/werebeing+p.p现在完成时态的被动语态：have/hasbeen+p.p过去完成时态的被动语态：hadbeen+p.p含有情态动词的被动语态：can/may/must...be+p.p主动句变被动句的方式：主动句：主语

一般来说，只有及物动词才有被动语态，因为只有及物动词才有承受者。但许多不及物动词加上副词或介词构成动词短语也相当于及物动词的用法，可以带宾语，因而也有被动语态。动词短语是不可分割的整体，在变被动语态时，不可丢掉构成动词短语的副词或介词。eg.Helooksafterhismother.Hismotherwaslookedafterbyhismother.1.OurschoolwillputofftheSchoolSportsmeetinguntilDecember.TheSchoolSportsmeeting_____________untilDecember.2.Peopletalked
