同位語從句

attributiveclausevsappositiveclause語法功能和概念先行詞引導(dǎo)詞1精選2021版課件語法功能和概念上的區(qū)別定語從句——形容詞性從句：

對先行詞的性質(zhì)、特征進(jìn)行描述

與先行詞是修飾與被修飾的關(guān)系（即修飾限定）同位語從句——名詞性從句：

對前面名詞進(jìn)一步的補(bǔ)充性解釋說明

它與前面的名詞是同位關(guān)系，即前面名詞是從句的概括總結(jié)，從句是前面名詞的具體內(nèi)容

名詞與該同位語從句有邏輯上的系表關(guān)系，可用“主+系+表”來構(gòu)成它們之間的邏輯關(guān)系，而定語從句與它所修飾的先行詞無法用be來構(gòu)成語法上的邏輯關(guān)系。（即解釋說明）2精選2021版課件語法功能和概念上的區(qū)別實(shí)例：＊Thereisafaintchancethatyouwillfindhimathome.若用“主+系+表”結(jié)構(gòu)來表示，則是“afaintchanceisthatyouwillfindhimathome”,這在邏輯上成立。實(shí)例：＊Itwasthechanceshehadbeenwaitingfor.而“thechanceisshehadbeenwaitingfor”這在邏輯上不成立。3精選2021版課件先行詞上的區(qū)別定語從句的先行詞可以是名詞，代詞，主句的一部分或是整個主句。同位語從句的先行詞是抽象名詞，如：idea，news，answer，fact，hope，thought，belief，order，truth，possibility等。同位語從句的先行詞往往沒有復(fù)數(shù)形式實(shí)例：ThemessagesthathewouldteachusEnglishcheeredusupyesterday.（×）注意：stage,situation,point,case,position,condition等詞一般用where引導(dǎo)定語從句，表達(dá)“階段、情況”4精選2021版課件先行詞上的區(qū)別實(shí)例：①Theboywhoisplayingfootballismyclassmate．②Thosewhoworkhardwillsucceed．③Thefactthathehadnotsaidanythingsurprisedeverybody．④Thefactthatyouaretalkingaboutisimportant．在①句中，其先行詞是普通名詞boy，是定語從句，它不能用作同位語從句的先行詞。在②句中，其先行詞是代詞those，是定語從句，代詞不能用作同位語從句的先行詞。在③句是同位語從句，其先行詞是名詞fact，它同樣可以用作定語從句的先行詞，④句便是一例。由以上分析可見，同位語從句的先行詞一定可以用作定語從句的先行詞，但定語從句的先行詞不一定能用作同位語從句的先行詞。5精選2021版課件引導(dǎo)詞的區(qū)別定語從句和同位語從句共同的引導(dǎo)詞有四個：that，when，where，why。引導(dǎo)詞如how,whether,what可以引導(dǎo)同位語從句但不能引導(dǎo)定語從句。*Weareinvestigatingthequestionwhetherheistrustworthy.6精選2021版課件引導(dǎo)詞的區(qū)別1．引導(dǎo)詞that引導(dǎo)定語從句的that叫做關(guān)系代詞，它除了起連接作用，還在定語從句中充當(dāng)成分（作賓語可省略），并且在意義上代表先行詞；引導(dǎo)同位語從句的that叫做從屬連詞，它只起連接作用且不可省略。實(shí)例：①Thenewsthatyoutoldmeyesterdaywasreallyexciting．②No

①句是定語從句，that在從句中作賓語，在意義上指代先行詞news。②句是同位語從句，that沒有任何意義，只起連接作用。7精選2021版課件引導(dǎo)詞的區(qū)別2．引導(dǎo)詞when，where，why引導(dǎo)定語從句時，它們叫做關(guān)系副詞，在從句中充當(dāng)狀語，可以轉(zhuǎn)換成"介詞＋關(guān)系代詞"的形式；引導(dǎo)同位語從句時，它們叫做連接副詞，在從句中充當(dāng)狀語，但不能轉(zhuǎn)換成"介詞＋關(guān)系代詞"的形式People
