高考英语定语从句和名词性从句讲解与综合训练名词从句有四类：宾语从句、主语从句、表语从句、同位语从句。例如：宾语从句：Idon’tknowwherehewillgo.主语从句：Wherehewillgoisunknown.表语从句：Theproblemishowwecangetsomuchmoney.同位语从句：Weallfeelsorryaboutthenewsthathefailedinthegame.下面几点是学习名词从句要加以注意的：1．whether和if都可以引导宾语从句表达“是否”意，（即引导宾语从句时if和whether可以互换）但以下几种名词从句要用whether（不用if）引导：（1）引导主语从句，且在句首时。例：Whetherhehaswonthetennisisnotknown.(但Itisnotknownwhether/ifhehaswonthetennis).（2）引导表语从句时。例Theproblemiswhetherhecangetajob.（3）引导同位语从句时。例：Ihavenoideawhetherhewillcome.（4）介词后的whether从句。例：IworryaboutwhetherIhurtherfeelings.2．位于句首引导主语从句的that不可忘。例如：Thathegotthefirstplaceinthecompetitionsurprisedallofus.3．在“Itissuggested/proposed/ordered/apity/nowonder/necessary/strange/⋯＋that从句”结构中，that从句谓语有时用（should）do这样的虚拟语气形式。例如：Itissuggestedthatwe(should)improvetherelationsbetweenus.Itisapitythatone(should)stayinoneplacealloneslife.Itisstrangethatsheshouldhavefailedtoseeherownshortcomings（缺点）.4．在“Thereasonwhy⋯isthat⋯”句式中that不要误为because.例如：Thereasonwhyhedidntgotoschoolyesterdayisthathewasill.5．名词从句中that,what用法比较：引导名词从句的that是连词，在句中无成份，无意义，而what是连接代词，what＝thething(s)that.例如：Itwastoldinyesterdaysnewspaperthatwhatthestudentshaddonewaspraisedthethings(that)无意义bythefactory.Iknowthathewillstudy.Iknowwhathewillstudy.Thatheworkshardathislessonsisknowntousall.Whatheworkshardatisknowntousall.AllIaskisthatyoushouldtellthetruth./Heisnotwhat(＝thepersonthat)heusedtobe.他和以前大不相同了。6．where在名词从句中的使用特点：where在名词从句中有时可以变为“theplacewhere”,有时可以变为“介词＋theplacewhere”形式。例如：主从：Where(＝Theplacewhere)shehasgoneisstillunknown.宾从：Wouldyoupleasetellmewhere(＝theplacewhere)MrSmithlives?表从：Yourdictionaryremainswhere(＝in/attheplacewhere)youput.同位从：Haveyouanyideawhere(＝oftheplacewhere)sheisspendingherholidays?7．无论是哪种名词从句都是陈述语序。例如：Iknowwherehelives./Pleasetellmewhathernameis.当一个特殊疑问句本身就是陈述语序（即“主＋谓＋（宾）”或“主＋系＋表”结构），将其变为间接引语（即宾语从句）时，无需改变语序。例如：Whatsthematterwithhim?Sheaskedmewhatwasthematterwithhim.Wholooksafteryourgrandfather?Heaskedmewholookedaftermygrandfather.名词从句考点分析1．Theywanttoknow______dotohelpus.(NMET)A.whattheycanB.howtheycanC.howcantheyD.whatcanthey析：此题要选陈述语序项，故应排除C、D。又因howtheycando不完整，do后无宾语，故也应排除，只有A项既是陈述语序，且whattheycando完整正确地表达出“他们能做些什么”这一意思，故答案为A。2．Histeacher______he______brightand______hewasworthteaching.A.didn’tthink;was;thatB.thought;was;whetherC.didn’tthink;was;×D.thought;wasnt;×析：观察题目，可知think后跟有and连接的两个并列宾语从句，这时前一个宾语从句的引导语that可以省略，但引导后一宾语从句的that不可省略，据此，可排除C、D两个选项。若选B项，全句意思不通，而选择A项可表达“他的老师认为他不聪明，不值得教”这一意思，且语法结构无误，故可定A是正确答案。3．______isdonecannotbeundone.A.HowB.ThatC.WhatD.Where析：do一般作及物动词使用，从题干看，需选一词作主语（逻辑上是done的宾语）。而A.How,D.Where均是副词，不能作主语，故应排除。B项that一词只能在定语从句中作主语...
