表语从句课件

ThePredicativeClause表语从句一、宾语从句的概念从句在复合句中作宾语的名词性从句，通常放在主句谓语动词（及物动词）或介词之后。E.g.WeknowMrGreenteachesEnglish.Sheaskediftheseanswerswereright.二、宾语从句三要素引导词（连接词）语序时态归纳：上述例句的结构：++句式观察句子结构，特别是划线部分。1.Iamalittle,littlebird.2.Thestoryisinteresting.3.Ourmainteacherishere.4.Everystudentisintheclassroom.5.Yourhomeworkistorecite劝学.6.Herjobissellingcomputers主语系动词/be表语4、Shebecameangryandmadetheweavinggirlreturntoheaven.3、Ifeelsickwithallthisfatandheavyfood.例句：5、Itmayseemluckytoyoubutnottome.1、HercustomersgetthinafterestingYong'food.2、Yonghuilooksill.常见的连系动词有：be（am,is,are,was,were）,become,look,sound,feel,taste(看、听、尝起来）,seem,appear（似乎、好像）等•Heisastudent.主语系动词表语•Thereasonisthatheisastudent.主语系动词表语从句•ThatiswhyIwaslate.主语系动词表语从句▲句子或主谓结构做表语（而不是某个具体单词做表语），这个句子就是表语从句。像这样含有两个及以上主谓结构的句子，并且其中一个句子在另一个句子中充当了成分，这样的句子就叫做复合句。指出句子成分〖合作探究〗一、表语从句定义：表语从句是在复合句中作表语的名词性从句,放在系动词之后,一般结构是“主语+系动词+表语从句”。作用:对主语进行解释说明。例句：1）Theproblemisthatmillionsofpeopledieofillnessescausedbysmoking.2）ThequestionremainswhetherwecanwinClass3.指出表语从句部分：1.Hehasbecomewhathewantedtobetenyearsago.2.ShehasremainedwhereIstoodyesterdayforanhour.3.Hissuggestionisthatweshouldstaycalm.4.Thequestioniswhenhecanarriveatthehotel.1.Hehasbecomewhathewantedtobetenyearsago.2.ShehasremainedwhereIstoodyesterdayforanhour.3.Hissuggestionisthatweshouldstaycalm.4.Thequestioniswhenhecanarriveatthehotel.二、引导表语从句的连接词由从属连词that引导的表语从句由连接代词Who,whom,whose,which,what和连接副词where,how,why,when引导的表语从句由从属连词whether，asif引导表语从句由从属连词because,why引导表语从句e.g.1.WhatIwanttosayisthatI’msorry.2.ThefactisthatIearnedmypassagebyworkingasanunpaidhand.（一）由从属连词that引导的表语从句that在从句中不充当任何成分，本身也没有任何意义。只是起连接作用。注：that在引导表语从句时不能省略。（二）由从属连词whether引导的表语从句1.Thequestionis______________________2.Thequestionis_______________________whetheritisworthdoing.whetherwecanwinthem.whether在句子中不充当任何成分，但具有“是否”的意义，表示对陈述的事物不明确或不清楚。此时不能用if，因为if不能引导表语从句。Thequestionis________wewillhaveoursportsmeetnextweek.A.thatB.ifC.whenD.whether注意点1：if不能引导表语从句Dasif/though引导表语从句时，在句子中也不充当任何成分，但有意义。译为：似乎，好像。Helooksasifhewerearichman.Itsoundsasifsomeoneisknockingatthedoor.他看起来好像是个富翁。听起来好像有人在敲门。（三）由从属连词asif/through引导的表语从句1.LiLeiisnowinanewjacket.HelooksasifhewereanAmericanboy.2.Thegirltalkedasifshehasbeenagrown-up.asif/through引导表语从句时要注意语气.若与事实相符，要用陈述语气。若从句表示与现在事实相反,谓动用；与过去事实相反用.考试中常考查这种虚拟语气，不考查陈述语气。一般过去式（be用were）had+done.这类词引出表语从句时，与它们引出宾语从句一样，要在从句中充当句子成分（一般充当主语、宾语、表语、定语或状语），并具有一定的意义，不可省略。(四）连接代词Who,whom,whose,which,what及连接副词where,how,why,when及wh-疑问词+ever引导的表语从句(2)Theproblemiswhowecangettoreplaceher.(3)Thequestionishowhedidit.（状语）(4)Thatiswherehewasborn.（状语）问题是我们能找到谁去替换她呢。（宾语）问题是他如何做此事的。那就是他出生的地方。(1)Thatiswhatheisworriedabout.(宾语）那就是他担心的事(1)That’sbecausehedidn’tunderstandme.(2)It’swhyhegotangrywithme.那是因为他不理解我。那正是他对我生气的原因。(强调原因）（强调结果）（五）由从属连词because,why引导的表语从句1、句型：That/Itis/wasbecause……那是因为……That/Itis/waswhy……那是……的原因2、句型：thereasonwhy……isthat…………的理由是……why引导定语从句That/Itis/waswhy……那是……的原因why引导表语从句(1)Thereasonwhyhewaslateisthathewasill.他迟到的理由是他病了。注意：主句主语为reason,只能用that引导表语从句，不可用because.(2)It’swhyhegotangrywithme.那正是他对我生气的原因。1.Thereasonwhyhefailedis________hewastoocareless.A.becauseB.thatC.forD.becauseof2.Thisis___Sarawaslateforthemeeting.A.whyB.whatC.howD.That3.Thereasonis___heisunabletooperatethemachine.A.becauseB.whyC.thatD.WhetherBCA三、表语从句语序表语从句的语序与宾语从句一样，不管是哪类连接词引导，也不管主句是否是疑问句，一律用陈述语序：主语+系动词+连接词+主语+谓语+其他成分注意：不管从句是由哪类连接词引出，一律用陈述句语序Theproblemis_________totaketheplaceofJohn.A.whocanwegetB.whatwecangetC.whowecangetD.thatwecangetCItiswherehelivesin.Itiswherehelivedin10yearsago.1.主句用现在时或将来时，从句可用任何时态，根据实际情况而定。三、表语从句时态2.如果主句是过去的时态（一般过去时，过去进行时），从句的时态一定要用相对应的过去的某种时态（一般过去时，过去进行时，过去将来时，过去完成时）Herwishwasthatshecouldloseweightsoon.Itlookedasifitwasgoingtorain.Thequestionwaswhetherhisfatherwouldcomebackthenextday.Thereasonwhyhewaslatewasthatthetrainhadalreadyleft.小结：1.表语从句的构成:引导词+简单句2.引导词:连词that,whether,asif连接代词who,what,which连词because,why3.语序:主从句时态呼应一致原则4.时态:陈述语序连接副词when,where,how,why1.Mariahastolookafterhersister.That’s_____shecan’tcomeoutwithus.A.whyB.howC.whenD.what2.Shelooked_____sheweretenyearsyounger.A.thatB.asif/throughC.asD.like3.ThereasonwhyIhavetogois_____ifIdon't.A.thatshewillbedisappointedB.becauseshewillbedisappointedC.onaccountofherbeingdisappointedD.thatshewillbedisappointing4.Itwas_____heworkedhardthathesucceeded.A.sinceB.becauseC.asD.for5.Whatthedoctorsreallydoubtis____mymotherwillrecoverfromtheseriousdiseasesoon．A.whenB.howC.whetherD.why6.—Areyoustillthinkingaboutyesterday’sgame?—Oh,that’s_____.(2003北京春)A.whatmakesmefeelexcitedB.whateverIfeelexcitedaboutC.howIfeelaboutitD.whenIfeelexcited7.Goandgetyourcoat.It’s___youleftit.A.thereB.whereC.therewereD.wherethere上面的题大家都做对了吗?上面每个句子都出现了的表语从句，大家能找到吗？80.Thingsaren’talways________.(appear)事情往往不是它们看上去的那样。(2012年湖北）whattheyappear(tobe)
