新概念英语第二册语法总结：名词性从句（4）同位语从句（四）同位语从句：在复合句中充当同位语。1.that引导同位语从句。在下列名词后可用that引导同位语从句answer,belief,doubt,fact,hope,idea,information,knowledge,law,news,opinion,plan,suggestion,thought,truth等。Ihadnoideathatyouwerehere.ThestorygoesthatWilliamkilledhiswife.Healwaysworkshardinspiteofthefactthatheisnotingoodhealth.Suddenlythethoughtcametomethathewouldgoblind.注意：①位语从句引导词that无含义，不充当成分，不可省略。②同位语从句与其说明的名词或代词为同一内容，故可以用is把前边的中心词和从句连接成一个句子。③同位语从句前一般没有逗号。that引导同位语从句与引导定语从句的区别：that引导同位语从句时只起连接作用，不充当任何成分；that引导定语从句时，在从句中要作成分，如主语、宾语等。①Hetoldmethenewsthatourteamwon.（that引导同位语从句）②Thenewsthat/whichhetoldmewasveryexciting.（that引导定语从句，在从句中作宾语）2.在noidea,question,problem等后可用wh-疑问词引导同位语从句，if不引导同位语从句。Ihavenoideawherehehasgone.Ihavenoideawhathesaid.3.辨析：引导名词性从句时what与whatever,who与whoever的区别：what与whatever：Whatyouwanthasbeensenthere.（what=thething(s)that/allthat/anythingthat特指）Whateveryouwantmakesnodifferencetome.（whatever=anythingthat泛指）Whatcausedtheaccidentwasabrokenbottle.（特指）Whatevercausedtheaccidenthasnotyetbeenfound.（泛指）who与whoever：WhowillgotoBeijingonbusinesshasnotbeendecided.（who表疑问，表示“谁”，“哪一个”）Whoeverbreaksthelawshouldbepunished.（whoever=anyonewho，表示“无论哪个人”）4.同位语从句注意与定语从句区别，同位语从句对前一名词做补充说明，在从句中无语法位置，而定语从句所修饰词在从句中占一语法位置如：Theideathatonecandotheworkwithoutthinkingiswrong.（同位idea在从句中无位置，而从句只是具体说明idea的内容）Theideathatyouputforwardatthemeetingiswrong.（定语从句，idea做putforward的宾语）专项训练：1.Itwastrue_____Alicedidsurprisedhermother.A.thatB.whatC.that,whatD.what,that2.Does____mattermuch____hecan'tcometothemeeting.A.it,ifB.that,ifC.it,whetherD.this,whether3.--Whatareyouanxiousabout?--____A.HowcanwesucceedB.WhetherwecansucceedC.WhencanwesucceedD.Thatwecansucceed4.Thereason____thelittleactresshasbeensuchasuccessis____sheisbothcleverandhard-working.A.why,whyB.why,thatC.that,becauseD.for,because5.____leavestheroomlastoughttoturnoffthelights.A.WhoB.WhoeverC.AnyoneD.Theperson6.Ireallydon'tknow_____Ihadthisphototaken.A.whereitwasthatB.itwasthatC.whereitwasD.itwaswhy7.Dr.BlackcomesfromeitherOxfordorCambridge.Ican'tremember____.A.whereB.thereC.whichD.that8.--WhatdoyouthinkofChina?--____differentlifeistodayfrom____itusedtobe.A.How,whatB.What,whatC.How,thatD.What,that9.Givethisto____youthinkcandotheworkwell.A.whoB.whomC.whoeverD.whomever10.____troublesmeis____Ican'tlearnalltheseEnglishidiomsbyheart.A.That,thatB.What,whatC.That,whatD.What,that（后设答案，大家不要偷看(⊙o⊙)哦，(*^__^*)嘻嘻……）KEYS1—5CABBB6—10ACACD
