一般过去时的被动语态的构成为：was/were+及物动词的过去分词。e.g.Thebridgewasbuiltlastyear.Thebridgewasn’tbuiltlastyear.—Wasthebridgebuiltlastyear?—Yes,itwas./No,itwasn’t.Whenwasthebridgebuilt?【拓展】1.

“不及物动词+介词/副词”构成的短语动词，变成被动句时，要把它们作为整体看待，介词或副词不可拆开或漏掉。e.g.MygrandmawaslookedafterbyanursecalledLisa.Theseposterswereputupbyourheadteacher.2.

含有双宾语的主动句变被动句时，可将主动句中的直接宾语或间接宾语变为被动句中的主语。如果把主动句中的直接宾语(指物)变为被动句中的主语，则需在间接宾语(指人)前加适当的介词to或for。

e.g.主动结构：Momboughtmeanewcoat.被动结构：Iwasboughtanewcoat.(间接宾语作主语)Anewcoatwasboughtforme.(直接宾语作主语)3.

有些动词常用其主动形式表示被动意义，如sell,wash,write等和表示感觉、知觉的系动词feel,sound,taste,smell等。e.g.Thiskindofpenwriteswell.Thesweaterfeelsverycomfortable.4.

在主动句中，使役动词(如make等)和感官动词(如see,watch,notice,hear等)后面常接不带to的动词不定式作宾语补足语；但在被动句中，这些词后面的动词不定式都需要带to。e.g.Tomwasmadetoanswerthequestionsinclassbytheteacher.Timwasseentorunintheplaygroundlastweekend.Grammar英语动词有两种语态：主动语态（ActiveVoice)和被动语态(PassiveVoice)。主动语态表示主语是动作的执行者，而被动语态则表示主语是动作的承受者。

e.g.Wecleanedtheclassroomyesterday.(主动语态，主语we是clean这一动作的执行者)Englishisspokenbymanypeople.(被动语态，主语English是动作speak的承受者。二、被动语态的构成

助动词be+及物动词的过去分词构成。助动词be有人称、数、和时态的变化。

一、语态三、被动语态的用法：1.不知道谁是动作的执行者，或没有必要指出谁是动作的执行者。

e.g.ThiskindofcarismadeinAmerica.

这款小汽车产自美国。2.需要突出或强调动作的承受者。

e.g.Thisdictionaryisusedbymoststudents.

这本字典是大多数学生在用的。四.主动语态变被动语态的步骤.Bellinventedthetelephonein1876.ThetelephonewasinventedBellin1876.

主动语态变被动语态的结构图:2.be+谓语动词的过去分词1.主语2.谓语动词过去式3.宾语时间状语3.主语3.宾语时间状语by

主动语态变被动语态的步骤：1、主动语态的宾语变为被动语态的主语；2、主动句的谓语动词变为被动式结构，即：be+及物动词的过去分词

3、主动句的主语变为被动句中by的宾语，当不

强调动作的执行者时，常省略。4.其它成分不变。Summary五、一般过去时被动语态的几种句型结构：肯定句主语+be(was,were)+及物动词的过去分词+(by…)Acakewaseatenbyamouselastnight.否定句
