Module2语法精讲—一般现在时的被动语态英语的语态是通过动词形式的变化现出来的。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者。例如：ManypeoplespeakChinese.谓语：speak的动作是由主语manypeople来执行的。被动语态表示主语是动作的承受者，即行为动作的对象。例如：Chineseisspokenbymanypeople.主语English是动词speak的承受者。Grammar被动语态的构成：be+Pp(动词的过去分词)人称、数和时态的变化是通过be的变化表现出来的。一般现在时被动语态的构成：am/is/are+Pp+(by+动作执行者)例如：Childrenlovethissong.(主动语态）（动作执行者）（动作承受者）Thissongislovedbychildren.(被动语态）（动作承受者）（动作执行者）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。把下列的句子变为被动语态的句子1、TheyspeakEnglishinCanada.　2、Peopleusewoodformakingtables.3、TheymakecomputersintheUSA.4、TheygrowriceinSouthChina.Englishisspoken(bythem)inCanada.Woodisused(bypeople)formakingtables.Computersaremade(bythem)intheUSA.Riceisgrown(bythem)inSouthChina.看谁最准确把下列句子变成被动句：MoreandmorepeoplespeakEnglish.2.Weplantmoretreeseveryyearhere.3.Dalianproducesbigships.4.Farmersgrowriceinsummer.5.Wecleanourclassroomeveryday.Englishisspoken(bymoreandmorepeople).Moretreesareplanted(byus)everyyearhere.BigshipsareproducedinDalian.Riceisgrown(byfarmer)insummer.Ourclassroomiscleaned(byus)everyday.QuizEnglish_________(speak)bymanypeople.Tea_________(grow)inSoutheastChina.Manytrees____________(plant)inNorthChina.Thebrush__________(make)ofbambooandanimal’shair.Confucius_________(know)asagreatthinkerinChina.isspokenisgrownareplantedismadeisknown1Shakespeare/see/asawonderfulwriterShakespeareisseenasawonderfulwrite.2hisplays/know/allovertheworldHisplaysareknownallovertheworld.3Shakespeare’sworks/stilllove/bymillionsofpeopleShakespeare’sworksarestilllovedbymillionsofpeople.4hisplays/turninto/wonderfulfilmsHisplaysareturnedintowonderfulfilms.5Shakespeare’splays/teach/inourschoolShakespeare’splaysaretaughtinourschool.6we/ask/performonepartofShakespeare’splaysWeareaskedtoperformonpartofShakespeare’splays.Quiz:RewritethesentencesLookatthepicturesandthenotes.Usethenotestodescribehowabookismade.HomeworkDoexercisesbook.(Page13---15)Thankyou!Goodbye!
