that/whether/who/whichwhat/when/where/why/how

若同位语从句的意义不完整，需要有“是否”的含义时，应用________；如果同位语从句意义不完整，需要有“谁”，“什么时候”，“在哪里”，“为什么”等含义时，分别可以用________，________，________，________等连词引导。whetherwhowhenwherewhy连接词that引导的同位语从句that在从句中不充当成分,只起连接作用.他告诉我一个消息,他马上要从国外回国.Thereisnodoubt

thatthepricesofcarswillgodown.只用whether引导,不用if.这个问题是否正确还未被证实.Theproblem________it

who,where,what,whetherandhow)1.同位语从句有时被别的词或短语把它和名词隔开：（谓语较短，同位语从句较长）注意:1:Thestorygoes

thatWilliamTellkilledthekingwithanarrow.2:Wordcame

thattheirteamhadwon.（word：n消息）分隔式同位语从句4.若被同位语从句说明的名词是：advice,suggestion,proposal,demand,request,requirement,order等表示建议、命令、要求的词时，同位语从句的谓语用"(should)+do"1).Imadethesuggestionthatthemeeting____________________(bring)toanend.(should)bebrought2).Theorderthatwe____________(send)afewpeopletohelpthemwasreceivedyesterday.3).Theorderthatwe__________(receive)yesterdaywasthatwe___________(send)afewpeopletohelpthem.(should)sendreceived(should)send注意:总结:1)同位语从句跟在名词后面，进一步说明该名词的具体内容。同位语从句常跟在名词

idea,fact,news,hope,thought,suggestion等抽象名词之后

2)连接词that不能省略,无意义无成分；3)用whether而不用if引导同位语从句

4)连接代词who,which,what在从句中作主语、宾语、表语或定语;连接副词where,when,why,how在从句作状语。

三.如何区别由that引导的定语从句和同位语从句1.定语从句中that，代词，可在从句中作主、宾、表同位语从句中that,连词，无成分无意义Thenewsthatourteamhaswonthegamewastrue.Thenewsthathetoldmeyesterdaywastrue.2.定义：定语从句---说明先行词的性质与特征，与先行词是修饰与被修饰的关系。

同位语从句---对名词即先行词加以补充说明，是名词全部内容的体现。3.在名词和从句之间加be,使之构成一个新句子，如果合乎逻辑，句子通顺，则是同位语从句，定语从句是不能用系表结构把先行词与从句连接起来的。Thenewsthatourteamhaswonthegame

wastrue.Thenewsthathetoldmeyesterday

wastrue.Thenewsisthatourteamhaswonthegame.Thenewsisthathetoldmeyesterday.(句子通顺，是同位语从句）（句子不通顺，是定语从句）判断下列从句是定语从句还是同位语从句：Thenewsthatyou'veheardisn'ttrue.Thenewsthatwe'llgoonapicnicthisSundayisn'ttrue.定语从句同位语从句()定语从句同位语从句1)ThenewsthathetoldmeisthatTomwouldgoabroadnextyear.2)ThenewsthatTomwouldgoabroadistoldbyhim.
