,WelcometoOurClass,TheActiveVoiceandPassiveVoice,学习目标和任务,下面各种时态的主动语态的构成结构,复习巩固,一般现在时：,主语+am/is/are+其它主语+v/v-(e)s+其它,一般过去式：,主语+was/were+其它主语+v-ed+其它,一般将来时：,主语+will/shall+v.原形+其它主语+begoingto+v.原形+其它,过去将来时：,主语+would/should+v.原形+其它,现在进行时：,主语+am/is/are+v-ing+其它,过去进行时：,主语+was/were+v-ing+其它,现在完成时：,主语+have/has+done+其它,过去完成时：,主语+had+done+其它,探索新知(一),主动语态改被动语态的方法：,主动语态：主语+谓语动词+宾语+其它（谁）（做）（什么）被动语态：主语+be的适当形式+by+主语（宾格变主格）及物动词的过去分词（主格变宾格）当主动语态中的主语为表示地点的名词时，在被动语态中应将其改为“in+名词”做地点状语。,归纳总结,把主动语态改为被动语态可按“一变、二套、三注意”来进行。即：变把主动语态的宾语改为被动语态的主语，把主动语态的主语改为被动语态的介词by的宾语(in+地点）。套根据原句的时态套用相应时态。注意注意人称的变化而引起的主谓一致问题。,探索新知（二）,各时态形式的被动语态的构成结构,一般现在时：主语+am/is/are+done+其它,一般过去时：主语+was/were+done+其它,一般将来时：主语+will/shall/begoingto+be+done+其它,过去将来时：主语+would/should+be+done+其它,现在进行时：主语+am/is/are+being+done+其它,过去进行时：主语+was/were+being+done+其它,现在完成时：主语+have/has+been+done+其它,过去完成时：主语+had+been+done+其它,含有情态动词的被动语态：主语+情态动词+be+done+其它,各种时态的主动语态和被动语态谓语结构对照表,主语+am/is/are+其它主语+v/v-(e)s+其它,主语+was/were+其它主语+v-ed+其它,主语+will/shall+v.原形+其它主语+begoingto+v.原形+其它,主语+would/should+v.原形+其它,主语+am/is/are+v-ing+其它,主语+was/were+v-ing+其它,主语+have/has+done+其它,主语+had+done+其它,主语+情态动词+v原形+其它,主语+am/is/are+done+其它,主语+was/were+done+其它,主语+will/shall+be+done+其它主语+begoingto+be+done+其它,主语+would/should+be+done+其它,主语+am/is/are+being+done+其它,主语+was/were+being+done+其它,主语+have/has+been+done+其它,主语+had+been+done+其它,主语+情态动词+be+done+其它,知识应用,将下列主动语态的句子变为被动语态。,1.Theboycleanedthedeskamomentago.,Thedeskwascleaned(bytheboy)amomentago.,2.Shewaterstheflowerseveryday.,Theflowersarewatered(byher)everyday.,3.Theydotheirhomeworkafterschool.,Theirhomeworkisdone(bythem)afterschool.,4.Tomiscuttingdownthetreesonthehill.,ThetreesarebeingcutdownbyTomonthehill.,知识应用,5.Wewillplant2000treesnextyear.,2000treeswillbeplanted(byus)nextyear.,6.Thepolicehavecaughtthethief.,Thethiefhavebeencaughtbythepolice.,7.Youmustkeeptheroomcleanandtidy.,Theroommustbekeptcleanandtidy.,8.Wehadlearnt3000wordsbytheendoflastterm.,3000wordshadbeenlearnt(byus)bytheendoflastterm.,9.NorthwestChinagrowsthebestcotton.,ThebestcottonisgrowninNorthwestChina,中考链接,FillintheblankswiththePassiveVoice.1、Tea_(grow)inFujian.2、Chinese_(speak)inChina.3、Thebeds_(use)forsleeping.4、Ourclassroom_(clean)yesterdayevening.5、Thecars_(make)inBeijing.,isgrown,isspoken,areused,wascleaned,weremade,小结：这节课我们学习了什麽?懂得了什么?,探索新知(一),主动语态改被动语态的方法：,主动语态：主语+谓语动词+宾语+其它（谁）（做）（什么）被动语态：主语+be的适当形式+by+主语（宾格变主格）及物动词的过去分词（主格变宾格）当主动语态中的主语为表示地点的名词时，在被动语态中应将其改为“in+名词”做地点状语。,探索新知（二）,各时态形式的被动语态的构成结构,一般现在时：主语+am/is/are+done+其它,一般过去时：主语+was/were+done+其它,一般将来时：主语+will/shall/begoingto+be+done+其它,过去将来时：主语+would/should+be+done+其它,现在进行时：主语+am/is/ar
