表语从句和定语从句的区别表语从句和定语从句的区别表语从句和定语从句的区别在于：范围不同、先行词作用不同、二者的`成分也不相同，以及结构也不相同。下面是小编整理的表语从句和定语从句的区别，一起来看看吧。表语从句紧跟在联系动词之后；而定语从句一般紧跟在先行词之后；另外，两种从句的功能也大不相同，表语从句是对主语的描述，解释或者身份的说明；而定语从句是对先行词的修饰或者限制。区别：定语从句所修饰的是名词，表语从句是接在系动词后面的做表语的成分，比如形容词例如:Thatiswhyhewaslateforclassthatday.（表语从句）Thatisthereasonwhyhewaslateforclassthatday.（定语从句）Thereasonwhyhewaslateforclassthatdaywasthattherewasatrafficjamonhisway.（此句中why引导的是定语从句,修饰thereason;而that是表语从句.【表语从句练习】1.Thequestionis________wewillhaveoursportsmeetnextweek.A.thatB.ifC.whenD.whether2．Thereasonwhyhefailedis________hewastoocareless.A.becauseB.thatC.forD.becauseof3.Goandgetyourcoat.It’s________youleftitA.whereB.thereC.therewhereD.wherethere4．Theproblemis_________totaketheplaceofTedA.whocanwegetB.whatwecangetC.whowecangetD.thatwecanget5.WhatIwanttoknowis______helikesthegiftgivenbyus.A.thatB.ifC.whetherD.不填答案：DBACC【定语从句练习】1.Marylivesintheroom,thedoor_____openseast.A.ofitB.ofwhichC.ofthatD.whose2.Theengineer_____myfatheristalkinghasjustcomefromabroad.A.withwhomB.withwhoC.withwhichD.that3.Helivesinahotel,_____isonlyfiveminutes’walkfromhere.A.thatB.whichC.inwhichD.where4.Isthereanything_____Icandoforyou?.A.whichB.whoC.asD.that5.Thespeakerwilltellusaboutsomewritersandtheirworks_____areknowntous.A.whichB.thatC.asD.who答案：1-5BABDB
