名词性从句
（二）
本期我们主要复习名词性从句中的同位语从句，下面我们以高考题为例来再现这一语法项目的运用。
考点一：
同位语从句
[考例回顾]
1.Thereisclearevidence_____themostdifficultfeelingofalltointerpretisbodilypain.
A.whatB.ifC.howD.that
2.Whenthenewscame_____thewarbrokeout,hedecidedtoserveinthearmy.
A.sinceB.whichC.thatD.because
3.—Isthereanypossibility_____youcouldpickmeupattheairport?
—Noproblem.
A.whenB.thatC.whetherD.what
4.Weshouldconsiderthestudents’request_____theschoollibraryprovidemorebooksonpopularscience.
A.thatB.whenC.whichD.where
[点拨]
1.答案为D。
that引导同位语从句，说明evidence的具体内容。
2.答案为C。
news与同位语从句分隔开，that引导的同位语从句说明news的具体内容。
3.答案为B。
that引导同位语从句，说明possibility的具体内容。
4.答案为A。
that引导同位语从句，说明request的具体内容，从句的谓语用虚拟语气。
[考点解读]
*同位语从句是用来解释或说明某一名词的内容的从句。
*同位语从句一般跟在某些名词如：
news,fact,idea,advice,suggestion,request,possibility,belief,doubt,opinion,thought,truth,report,warning等后面。
*同位语从句的引导词有that,whether,why,who,where,how,when等。
*名词doubt后的同位语从句，肯定句用whether引导,否定句或疑问句用that引导。
如：
Shehadherdoubtswhetherhewouldcome.
SomeresearchersbelievethatthereisnodoubtthatacureforAIDSwillbefound.
*有时，同位语从句可以不紧跟在说明的名词后面，而被别的词隔开。
*表示“建议、命令、要求”等的名词如command,order,demand,request,suggestion等后的同位语从句中谓语要用虚拟语气，即“（should+）动词原形”。
如：
Hereismysuggestionthathe（should）besenttoworkinAmerica.
考点二：
同位语从句与定语从句的区别
[考例回顾]
1.Modernsciencehasgivenclearevidence_____smokingcanleadtomanydiseases.
A.whatB.whichC.thatD.where
2.Theoldtownhasnarrowstreetsandsmallhouses_____arebuiltclosetoeachother.
A.theyB.whereC.whatD.that
[点拨]
1.答案为C。
that引导同位语从句，说明evidence的具体内容，that在从句中不作任何成分。
2.答案为D。
that引导定语从句，修饰先行词houses，that在从句中作主语。
[考点解读]
*同位语从句是对名词进行解释或说明，而定语从句则是对先行词进行限定和修饰。
*同位语从句前面的名词通常是固定的一部分名词，而定语从句的先行词可以是任何的名词或代词。
*that引导同位语从句时，在从句中不作成分，不能省略；而在定语从句中要指代先行词，可以在从句中作主语、宾语或表语，在作宾语时可以省略。
[拓展]
*that可以用在名词性从句、定语从句、强调句型中，高考常对其进行综合考查。
请体会以下句子中that的用法：
Thisisthefactthathehasfailedinhisdrivingtest.
（同位语从句）
Itisknowntousallthathehasfailedinhisdrivingtest.
（主语从句）
Weallknow（that）hehasfailedinhisdrivingtest.
（宾语从句）
Thereasonwhyheisblueisthathehasfailedinhisdrivingtest.（表语从句）
Thisisthefactthatmakeshimfeelblue.（定语从句）
Itisbecausehehasfailedinhisdrivingtestthatheisbluetoday.（强调句型）
