高中英语名词性从句讲解

1、合用文档名词性从句讲解在复合句中起名作用的从句叫做名性从句。它包括主从句、从句、表从句和同位从句。名性从句是中学段的一个重要法目，在年的高考中几乎都涉及到，并且每年的命各有化。分析届高考名性从句考的焦点主要有以下六个方面1.考名性从句的序2.考引that与what的区3.考it在名性从句中作形式主或形式的用法4.考whether与if的区5.考名性从句中的疑+ever引的名性从句与nomatter+疑引的状从句的区考名性从句的虚气法要点分析一、名性从句主从句、表从句、从句、同位从句，在整个句子中所起的作用，相当于一个名。因此，四种从句通称名性从句。引名性从句的接可分三：接：that,wheth

2、er,if（不充当从句的任何成分）接代：what,whatever,who,whoever,whom,whose,which.接副：when,where,how,why1.主从句作句子主的从句叫主从句。主从句平时由隶属that，whether，if和接代what，who，which，whatever，whoever以及接副how，when，where，why等引。that在句中无，只起接作用；接代和接副在句中既保留自己的疑含、又起接作用，在从句中充当从句的成分。比方：Whathewantstotellusisnotclear.他要跟我什么，不清楚。Itisknowntoushowhebecam

3、eawriter.我都知道他是怎样成一名作家的。WheretheEnglisheveningwillbeheldhasnotyetbeenannounced.英晚会将在哪里行，没有宣布。有防备句子重脚，常用形式主it代替主从句作形式主放于句首，而把主从句置于句末。主从句后的一般用数形式。常用句型以下：（1）It+be+名+that从句（2）It+be+形容+that从句（3）It+be+的去分+that从句（4）It+不及物+that从句另注意在主从句中用来表示惊诧、不相信、惋惜、理这样等气，要用虚气“(should)+do”，常用的句型有：Itisnecessary(important,na

4、tural,strange,etc.)thatItisapity(ashame,nowonder,etc.)thatItissuggested(requested,proposed,desired,etc.)that从句名句用作的从句叫从句。引从句的关与引主从句表从句的关大体一，在句中能够作或介及非的。1.由接that引的从句由接that引从句，that在句中不担当任何成分，在口或非正式的文体中常被省去，但如从句是并列句,第二个分句前的that不能省。比方：HehastoldmethathewillgotoShanghaitomorrow.他已告我他明天要去上海。Wemustneverthin

5、k(that)wearegoodineverythingwhileothersaregoodinnothing.我决不能够自制什么都好，人什么都不好。注意：在demand、order、suggest、decide、insist,desire,demand,request,command等表示要求、命令、建、决定等意的后，从句常用“（should）+原形”。比方：Iinsistthatshe(should)doherworkalone.我持要她自己工作。文案大全合用文档Thecommanderorderedthattroops(should)setoffatonce.司令员命令队伍马上出发。2.

6、用who，whom,which,whose,what,when,where,why,how,whoever,whatever,whichever等关系词引导的宾语从句相当于特别疑问句，应注意句子语序要用陈述语序。比方：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，她都会恩赐热情的支持。3.用whether或if引导的宾语从句，其主语和谓语的序次也不能够颠倒，仍保持陈述句

7、语序。其他，whether与if在作“可否”的意思讲时在以下情况下一般只能用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“ornot”时；e.后接动词不定式时。比方：Whetherthereislifeonthemoonisaninterestingquestion.月球上有没有生命是个幽默的问题。Everythingdependsonwhetherwehaveenoughmoney.所有要看我们可否有足够的钱。注意宾语从句中的时态响应，当主句动词是现在时，从句依照自己的句子情况，而使用不相同时态。比方：hestudiesEn

8、glisheveryday.（从句用一般现在时）hestudiedEnglishlastterm.（从句用一般过去时）Iknow(that)hewillstudyEnglishnextyear.（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。比方：TheteachertoldusthatTomhadleftusforAmerica5.think,believe,im

9、agine,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。马上从句中的否定形式移到主句中。比方：Wedontthinkyouarehere.我们认为你不在这。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。引导表语从句的关系词与引导主语从句的关系词大体相同，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。比方：Thefactisthatwehavelostthegame.事实是我们已经输了这场比赛。Thatiswhyhedidntcometothemeeting.那就是

10、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。比方：Thereasonwhyhewaslatewasthathemissedthetrainbyoneminutethismorning名词性从句专项练习100题1.Hissuccesswasbecauseof_hehadbeenworkinghard.A.thatB.thefactwhichC.thefactthatD.thefact2.“IsMaryfromNewYorkCity”“Idontknow_.”A.fr
