在主从复合句中，跟在一个名词后（尤其是抽象名词）对其作出进一步解释说明(其内容)的从句叫做同位语从句。

能跟同位语从句名词一般是advice,doubt,fact,news,idea,truth,hope,problem,word,information,message,wish,promise,answer,evidence,report,explanation,suggestion,conclusion等抽象名词。eg.Iwasshockedatthenewsthatourteamwonthegame.Ihavenoideawhatheisdoingnow.二、

同位语从句的引导词类别例词说明连接代词who,whom,what,which,whose,有意义，在从句中做主宾表定连接副词when,where,how,why有意义，在从句中作时间地点方式原因状语从属连词that,whether不做成分，that无意义，whether为“是否”之意例句呈现1.Iheardthenewsthatourteamhadwon.2.Icomeherewithamessagethathewouldbeabsent.3.Thestorygoesthathewasrescuedatlast.4.Therumerspreadthatanewschoolwillbebuilthere.5.Hemustanswerthequestionwhetherheagreeswithitornot.6.Ihavenoideawhowillgothere.7.Ihavenoideawhichbookyoulikebest.8.Ihavenoideawhatsizeshoesshewears.9.Wehaven’tsettledthequestionwherewearegoingtolive.10.Ihavenoideawhenhewillcomebackhome.11.YouhavenoideahowworriedIwas.12.Shehasnoideawhyheburstintotears.三、注意事项①分隔式同位语从句。当主句的谓语动词太短，而同位语从句又太长时，同位语从句与其所说明的名词会被其他成分分开，从而形成分隔式同位语从句，主要是为了保持句子平衡，避免头重脚轻。eg.WordcamethatwewillhavelessonsonSaturdays②名词suggestion,order,demmand,command,request,desire,proposal等名词后的同位语从句要用虚拟语气，即从句的谓语动词要用shuolddo的形式，should可以省略。③名词doubt之后课跟同位语从句，主句为肯定句用whether引导，主句为否定句时用that引导。eg.Thereissomedoubtwhethertheywillcometohelpus.ThereisnodoubtthatTaiwanbelongstoChina.④同位语从句与定语从句的区别*

同位语从句对前面的名词作进一步的解释说明或补充内容；定语从句对先行词修饰限定缩小其范围。*

同位语从句所说明的名词通常为抽象名词；定语从句的先行词无此限制。*
