同位语从句与

定语从句的区别一、同位语从句相当于一个名词，对前面的名词起解释说明作用，而定语从句相当于一个形容词，对前面的名词、代词起修饰限制作用。Thefactthattheywonthegamepleasedallofthem.Thenewsthattheytolduscheeredusall.(thatclause=thefact)(that指代thenews)Suddenlythethoughtcametomethathecouldgoblind.Thethoughtthathecouldgoblindmademefeelsad.Thethoughtthatsuddenlycametomeisterrible.(同位从句)（同位从句）（定从）名词idea,word,news,promise,fact,information,problem,question,hope,truth,suggestion,doubt,fear,belief等后常跟一个同位从句来说明该名词的内容，解释其内涵。Hemadeapromisethatwhoevercouldsethimfree,hewouldshowhimallthetreasuresintheworld.Word(News)camethatourteamwonthegame.WhowillgotofindouttheinformationwhentheywillsetouttovisittheGreatWall?引导同位语从句的that,whether,when,where,who,how,why等不等于或不能替换前面的名词或代词,这些引导词在同位语从句中均不能省略,引导同位语从句的连接副词when,where,who,how等在同位词从句中作状语时,有疑问意义。that无实义不作句子成分(如上述例子)；01而定语从句的引导词要在从句中担任句子成分，that,which,who/whom等作从句宾语时常可省略。02Ihaveknownthefactthat(不等于fact)ourschoolhasgonefaraheadofanyotherschoolinourcountryeveryaspect.Hewouldnottellustheideawhether(不等于idea)hewaswilingtohelpusoutofdifficulty.Icouldhardlybelievethereasonwhy(不可替换reason)hewaslateagain.(why有疑问意义)123Theyhavenoideawhere(不可替换idea)hehasgone.4但以下例句则为定语从句，引导词就是先行词的替身。Thenews(that,which)hegaveuswastrue.Theypassedoutusalotofinformationthatisofgreatuse.Heistheonlyoneofthestudentswhohasbeenawinnerofscholarshipforthreeyears.Exercises:
