定义：在句中起名词作用的从句，可以作为一个整体看待，其作用就相当于一个名词。类别：主语从句；表语从句；同位语从句；宾语从句。连接词：名词性从句通常用一个连接词和主句连接。连接代词what，which，who，whom，whatever，whichever，whoever，whomever等，在从句中作主语、宾语、表语、定语连接副词when，where，how，why等，在从句中作状语从属连词that，whether，if，asif/though等，在从句中不作成分特点：名词性从句要用陈述语序，即：连接词＋主语＋谓语AtpresentIknowhowIcanapplytheorytopractice.WhatIshoulddonowisgraspthepreciouschance.一、主语从句(在复合句中作主句的主语)1.that，whether引导的主语从句Thattheyshouldgetwellpreparedfortheirfutureisobvioustothestudents.＝Itisobvioustothestudentsthattheyshouldgetwellpreparedfortheirfuture.显而易见，学生应该为自己的未来做好准备。Whetherhewillsucceedremainstobeseen.＝Itremainstobeseenwhetherhewillsucceed.他是否会成功还有待观察。小结：that引导主语从句不可省略；whether可以引导主语从句，而if不可以。2.以连接代词和连接副词引导的主语从句常保留各自的疑问词义Whythefirebrokeoutisstillunknown.＝Itisstillunknownwhythefirebrokeout.人们仍然不知道这场大火为何会发生。HowhecanlearntoappreciateChinesecultureremainsanimportantgoalforhim.如何学会欣赏中国文化对他来说仍然是一个重要目标。Duringthisperiod，whateverpeopleexperienceisfreshandexciting.在这期间，人们所经历的任何东西都是新的、令人兴奋的。Whatwecan’tgetseemsbetterthanwhatwehave.我们得不到的东西似乎比我们拥有的要好。小结：如果主语从句过长，可以用it作形式主语。3.it作形式主语还常有下列句型Itis＋名词(afact，apity，aquestion，nowonder...)＋that从句Itis＋形容词(necessary，strange，important，possible...)＋that从句Itis＋过去分词(said，reported，decided，believed，suggested，ordered...)＋that从句It＋动词(短语)(seem，happen，turnout，occurto...)＋that从句Itisapitythatshehasmadesuchasillymistake.她犯了这样一个愚蠢的错误，真是遗憾。Itisveryimportantthatastudent(should)learnEnglishwell.学生学好英语很重要。Itissuggestedthatthemeeting(should)beputoff.有人建议会议延期召开。Itseemsthatheisnotquitehimselftoday.他今天好像不怎么舒服。二、宾语从句(在复合句中作及物动词或介词的宾语)1.作及物动词和介词的宾语Histutorexplained(that)heshouldreadmorebooks.他的导师解释道他应该多读书。Iwilldowhat/whateverIcan(do)tohelphim.我会尽我所能去帮助他。Iwonderwhether/iftheywillcometoourparty.我想知道他们是否会来参加我们的晚会。Sheaskedmewhosehandwritingwasthebestintheclass.她问我谁的书法是班上最好的。Amoderncityhasbeensetupinwhatwasonceawasteland.一座现代城市已经在曾是废墟的地方建起来了。Itdependsonhowwesolvetheproblem.这取决于我们如何解决这个问题。2.it作形式宾语常见结构有：(1)find，consider，think，feel，believe，make＋it＋adj./n.＋宾语从句(2)enjoy，love，like，hate，appreciate，seeto，insiston，dependon，relyon＋it＋宾语从句IhavemadeitclearthatIwillnotacceptthisjob.我已经表明我不会接受这份工作。Ihateitwhenpeopleaskmeformoney.我不喜欢别人向我要钱。Iwouldappreciateitifyoucouldconsidermyapplication.如果您能考虑我的申请，我将不胜感激。3.观察下列例句，总结宾语从句的特殊用法(1)Hetoldme(that)hehadtwosonsandthattheybothhadgonetocollege.他告诉我他有两个儿子，他们都去上大学了。(2)I’mthinkingofwhetherweshouldgotoseethefilm.我正在考虑我们是否应该去看电影。Ican’tsaywhetherornottheycancometomorrow.我不敢说他们明天是否能来。Shedidn’tknowwhethertogoortostay.她不知道是走还是留下。总结：(1)当and连接两个或者两个以上that引导的宾语从句时，只有第一个宾语从句可省略that，后面的宾语从句中的that不能省略。(2)作介词宾语、与ornot连用或与不定式连用时，只用whether不用if。三、同位语从句在复合句中用作同位语的从句称为同位语从句。它一般放在fact，news，idea，truth，hope，problem，information，belief，thought，doubt，promise，question等抽象名词的后面，对前面的名词作进一步的解释，或说明前面名词的具体含义。同位语从句通常由that引导，也可由whether引导，或由连接代词(what，which，who，whose等)和连接副词(when，where，why，how等)引导。Thenewsthattheyhadwonthegamesoonspreadoverthewholeschool.他们比赛获胜的消息很快传遍了整个学校。Hehasn’tmadethedecisionwhetherhewillgothere.他还没有做出决定是否去那里。Ihavenoideawherehelives.我不知道他住在哪里。Thequestionwhoshoulddothejobrequiresconsideration.谁应该做这项工作的问题需要考虑。同位语从句和定语从句的区别：(1)从意义上看，同位语从句是对一个名词的具体内容加以解释说明；定语从句是对名词进行修饰限定。(2)从结构上看，that引导同位语从句时，不作成分；that引导定语从句时作成分。比较：Hetoldmethenewsthatourteamwon.(同位语从句)Hetoldmethenewsthatwasexciting.(定语从句)四、表语从句(在复合句中作表语，位于系动词之后)(具体用法讲解见UNIT1)ThetroubleisthatIhavelosthisaddress.麻烦是我把他的地址弄丢了。Iwasveryangry.Thatwasbecausehedidn’tcome.我很生气，那是因为他没来。(强调原因)Hedidn’tcome.ThatwaswhyIwasveryangry.他没来，那就是为什么我很生气。(强调结果)ThereasonwhyIwasveryangrywasthathedidn’tcome.我很生气的原因是他没来。Thequestioniswhetherhecanmakeit.问题是他能否成功。练习1.
