探究一：主动语态和被动语态的概念和转换主动语态：主语AlexanderGrahamBell是动作invent的执行者。主动语态被动语态被动语态：主语Thetelephone是动作invent的承受着。AlexanderGrahamBellinventedthetelephonein1876.Thetelephonewasinvented(byAlexanderGrahamBell)in1876.主动语态被动语态主(执行者)谓宾(承受者)①②③主(承受者)谓by(执行者)Practice将下列句子改为被动语态Weplantedtreeslastweek.主动语态变被动语态解题步骤1.找宾语----即动作的承受者2.判断宾语的单复数----即be动词的单复数.3.把谓语改成was/were+V.过去分词5.修改原句的主语----即by+主语/宾语.宾变主,主变宾,前加by动变被,看清be,结构分别be+ppTree

byhim.主动语态变为被动语态的注意事项：几种特殊的被动语态①“不及物动词+介词/副词”(介词/副词不与动词拆开或漏掉)e.g.Themancutdownthetree.→②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带to。e.g.WeheardMarysinginthenextroom.→

感官动词一感二听三让四看主动句中to离开，被动句中to回来

WeoftenheardKatesingintheroom.

Thetreewascutdownbytheman.Marywasheard

tosinginthenextroom.Katewasoftenheardtosingintheroom(byus).③含有双宾语的主动句变被动句时，如果直接宾语(物)作主语，则需在间接宾语(人)前加介词to或for。e.g.Petergaveme

apen.间接宾语直接宾语a.IwasgivenapenbyPeter.④

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.Thiskindofdresssellswell.Thefishtastesverydelicious.含有双宾语的主动句变为被动语态时，通把指“人”间接宾语变为主语，而指“物的直接宾语则不变如果要把指“物”的直接宾语变为主语，则在间接宾语前加to或for。b.ApenwasgiventomebyPeter.

这件毛衣正以低价出售。low形容词，意为“低的”。eg：Shejumpedoverthelowwall.她跳过了那堵矮墙。1.atalowprice以低价LanguagepointsAtpresent,thepriceofthehousesinUrumqi_______thanbefore.Icanafford______alargeone.(乌鲁木齐)A．arecheaper；tobuy

B．ischeaper；buyC．arelower；buyD．islower；tobuy【点拨】本题用分析句意法解题。句意：现在，乌鲁木齐市房子的价格比以前低，我可以负担得起买一套大房子。thepriceofthehouses作主语，应用low或high表示，且谓语动词用单数。affordtodosth.负担得起做某事。

Dlow低主语是价格，不能是物品本身high高cheap廉价；便宜的主语不能是价格，必须是物品本身expensive昂贵的；花钱多的“高低贵贱”的用法

拓展【易错点】eg：TodayinTokyothelowesttemperatureis16℃，andthehighestis28℃.今天东京的最低气温是16℃，最高气温是28℃。Thepriceofthiswatchisveryhigh.这只表的价格很高。Thepriceofthisbookisnotlowforme.这本书的价格对我来说不低。Thiswatchisexpensive.这只表很贵。Thisclothdollisverycheap.这个布娃娃很便宜。o...意为“把……翻译成……”，既可用于主动语态中，也可用于被动语态中。eg：Don’ttranslateeverythingintoChinesewhenyoureadEnglisharticles.

当你阅读英语文章时，不要把所有的东西都翻译成汉语。WillthebookbetranslatedintoEnglishassoonaspossible?这本书会尽快翻译成英文吗？

2.translate/træns'leɪt/v．翻译DoyouknowMoYan?Hisbooks________intoEnglishafewyearsago.A．weretranslated

B．translatedC．aretranslatedD．translates【点拨】本题用语法判定法解题。句意：你知道莫言吗？他的书几年前被翻译成英文。本句为被动语态，根据句中的时间状语afewyearsago可知用一般过去时。

A一、用所给动词的适当形式填空1.Thepizza__________(make)byme.Wouldyouliketohavesome?2.TheGreatWall_________(know)allovertheworld.
