名词性从句讲解及专项练习习题及其解答

1、名词性从句讲解一、名词性从句主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。因此，这四种从句通称为名词性从句。引导名词性从句的连接词可分为三类：连接词：that,whether,if(不充当从句的任何成分)连接代词：what,whatever,who,whoever,whom,whose,which.连接副词：when,where,how,why主语从句作句子主语的从句叫主语从句。主语从句通常由从属连词that,whether,if和连接代词what,who,which,whatever,whoever以及连接副词how,when,where,why等词引导。

2、that在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分。例如：Whathewantstotellusisnotclear.他要跟我们说什么,还不清楚。Itisknowntoushowhebecameawriter.我们都知道他是如何成为一名作家的。WheretheEnglisheveningwillbeheldhasnotyetbeenannounced.英语晚会将在哪里举行,还没有宣布。有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下：

3、(1)It+be+名词+that从句(2)It+be+形容词+that从句(3)It+be+动词的过去分词+that从句(4)It+不及物动词+that从句另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should)+do”，常用的句型有：Itisnecessary(important,natural,strange,etc.)thatItisapity(ashame,nowonder,etc.)thatItissuggested(requested,proposed,desired,etc.)that宾语从句名词句用作宾语的从句叫宾语从句。引导宾语从

4、句的关联词与引导主语从句表语从句的关联词大致一样,在句中可以作谓语动词或介词及非谓语动词的宾语。由连接词that引导的宾语从句由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时，第二个分句前的that不可省。例如：HehastoldmethathewillgotoShanghaitomorrow.他已经告诉我他明天要去上海。Wemustneverthink(that)wearegoodineverythingwhileothersaregoodinnothing.我们决不能认为自己什么都好,别人什么都不好。注意：在demand、or

5、der、suggest、decide、insist,desire,demand,request,command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用(should)+动词原形”。例如：Iinsistthatshe(should)doherworkalone.我坚持要她自己工作。Thecommanderorderedthattroops(should)setoffatonce.司令员命令部队马上出发。用who,whom,which,whose,what,when,where,why,how,whoever,whatever,whicheve等关联词引导的宾语从句相当于特殊疑问句

6、,应注意句子语序要用陈述语序。例如：Iwanttoknowwhathehastoldyou.我想知道他告诉了你什么。Shealwaysthinksofhowshecanworkwell.她总是在想怎样能把工作做好。Shewillgivewhoeverneedshelpawarmsupport.凡需要帮助的人,她都会给予热情的支持。用whether或if引导的宾语从句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。此外,whether与if在作“是否”的意思讲时在下列情况下一般只能用whether，不用if：a.引导主语从句并在句首时；b.引导表语从句时；c引导从句作介词宾语时；d.从句后有o

7、rnot”时；e.后接动词不定式时。例如：Whetherthereislifeonthemoonisaninterestingquestion.月球上有没有生命是个有趣的问题。Everythingdependsonwhetherwehaveenoughmoney.一切要看我们是否有足够的钱。4.注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用不同时态。例如：hestudiesEnglisheveryday.（从句用一般现在时）hestudiedEnglishlastterm.（从句用一般过去时）Iknow（that）hewillstudyEnglishnextyea

8、r.（从句用一般将来时）hehasstudiedEnglishsince1998.（从句用现在完成时）当主句动词是过去时态（could,would除外），从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。例如：TheteachertoldusthatTomhadleftusforAmerica5.think,believe,imagine,suppose等等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。例如：Wedontthinkyouarehere.我们认为你不在这。

9、Idontbelievehewilldoso.我相信他不会这样做。表语从句在句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用asif引导。其基本结构为：主语+系动词+that从句。例如：Thefactisthatwehavelostthegame.事实是我们已经输了这场比赛。Thatiswhyhedidntcometothemeeting.那就是他为什么不到会的原因。Itlooksasifitisgoingtorain.看上去天要下雨了。需要注意的，当主语是reason时，表语从句要用that引导而不是because。例如：Ther

10、easonwhyhewaslatewasthathemissedthetrainbyoneminutethismorning同位语从句同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如：Thenewsthatwewonthegameisexciting.我们赢得这场比赛的消息令人激动。Ihaveno

11、ideawhenhewillcomebackhome.我不知道他什么时候回来。ThethoughtcametohimthatMaryhadprobablyfallenill.他想到可能玛丽生病了。同位语从句和定语从句的区别：that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略；that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。试比较下面两个例句:Ihadnoideathatyouwerehere（that引导同位语从句，不能省略）Haveyougottheidea（that）thisbookgivesyouoflifeinancien
