1、PassivevoicePassivevoice英语中有两种语态：主动语态和被动语态。主动语态的主语是动作的执行者，被动语态中的主语是动作的承受者，即主动语态中的宾语。所以只有及物动词才有被动语态。一、被动语态的构成：被动语态由“be+及物动词的过去分词”构成。be动词要随着人称和数的变化而变化。规则动词的过去分词与动词的过去式一样直接加-ed，不规则动词的过去分词有自己的特殊形式。被动语态的时态是通过be的变化来表示的。请看下列3种。1.一般现在时：主动：do/doesWecleantheclassroom

2、everyday.DoManypeoplespeakEnglishintheworld?被动：be(am,is,are)+done(及物动词的过去分词)Theclassroomiscleanedeveryday.每天都要打扫教室。IsEnglishspokenbymanypeopleintheworld?世界上好多人都要讲英语吗？2.一般过去时：主动：didTheboybrokethewindowyesterday.Didtheybuildthebridgelastyear?被动：be的过去时（was,wer

3、e）+doneThewindowwasbrokenbytheboyyesterday.昨天那个孩子把窗子打碎了。Wasthebridgebuiltlastyear(bythem)?这座桥是去年建的吗？3.一般将来时主动：willdoWewillfinishtheworkintwodays.Thedoctorwilloperateonhimnextmonth被动：willbedoneTheworkwillbefinishedintwodays(byus).Hewillbeoperatedonnextmonth(

6、shouldbespokentopolitely.对老年人讲话要有礼貌。注意：此时的do,does,did和done(过去分词)必须是及物动词。不及物动词后无宾语，所以无法改为被动语态。一般现在时：is/are+-ed一般过去时：was/were+-ed一般将来时：willbe+-ed过去将来时：wouldbe+-ed现在进行时：is/arebeing+-ed过去进行时：was/werebeing+-ed现在完成时：have(has)been+-ed过去完成时：hadbeen+ed由上表中我们可以看出，不管是
