名詞性從句高考趨勢與考察重點一、語序問題---名詞性從句內部一律使用陳述語序注意以下句子：.Idon’tknowwhatisthematterwithhim.Ihavenoideawhatwasthematterwithhim.Couldyoutelluswhatwaswrong/thetroublewithhimyesterday二、從句中的虛擬語氣問題1.主語從句：(1)Itisimportant/natural/necessary/essential/strange/that…(should)do…(2)Itissuggested/advised/demanded/ordered/requestedthat…(should)do….Itisimportantthateverystudent(should)learnaforeignlanguage.Itissuggestedthatstudents(should)checktheiranswersbeforehandinginthepaper.2.賓語從句：在表示“命令、要求、建議、決定”等意義的動詞后的賓語從句常用“（should）+do”【insist（堅持），order,urge,command（命令），require,request,demand（要求），advise,suggest,propose,recommend（建議）】.Thecommanderorderedthattroops(should)setoffatonce.Thedoctorsuggestedthathe(should)giveupsmoking.3.表語從句：當主句的主語為order,command,requirement,request,demand,advice,suggestion,proposal,recommendation等名詞時，表語從句的謂語動詞用“(should)do”的形式。.Myadviceisthatyou(should)takemorephysicalexercise.4.同位語從句：用于解釋order,command,requirement,request,demand,advice,suggestion,proposal,recommendation等名詞的同位語從句中常用“(should)do”結構.Englishteachersgiveadvicethatwe(should)makegooduseofeverychancetospeakEnglish.三、連接詞的選擇問題1.doubt---doubt用于肯定結構時，后面用whether引導名詞性從句；用于否定結構或疑問結構時，后面用that引導名詞性從句。.Idoubtwhetherhetoldthetruth.Idon’tdoubtthathetoldthetruth.Thedoctor’sdoubtiswhethermymotherwillrecoverfromthediseasesoon．IhavenodoubtthatTomisatalentedactor.2.sure---besure用于肯定句或疑問句時，后接that引導的名詞性從句；用于否定句時，后接whether引導的名詞性從句。.I’msurethatI’vefoundtheanswertothisquestion.Areyousurethatyou’vefoundtheanswertothisquestion.I’mnotsurewhetherI’vefoundtheanswertothisquestion.3.主語是reason時，表語要用that引導而不是because：.Thereasonwhyhewaslatewasthathemissedthetrainbyoneminutethismorning.4.what和that---that在從句中不充當成分，不含疑問意義，而what在從句中充當主語、賓語或表語，且含有疑問意義。.ThatTomfelloffhischairbyaccidentgottheclassmateslaughing.WhatTomlearnedinuniversityhelpshimalotinhisjob.=AllthatTomlearnedinuniversityhelpshimalotinhisjob.5.連接詞wh-和wh-ever選擇---前者表示一個特指概念，引導的名詞性從句含有疑問意義；后者表示一個泛指概念，意為“任何……”，引導的名詞性從句不含有疑問意義，相當于名詞后加一個定語從句。.Itwasamatterofwhowouldtaketheposition.Sarahhopestobecomeafriendofwhoeversharesherinterests.(=anyonewhosharesherinterests.)Theywilldowhateverhewantsthemtodo.(=anythingthathewantsthemtodo)6.This/Thatiswhy…和This/Thatisbecause….ThereasonwhyIcamelateisthatmycarbrokedownonthehalfway.→Hecamelate.That’sbecausehiscarbrokedown.→Hiscarbrokedownonthehalfway.That’swhyhecamelate.7.幾個特殊句型之間的轉換ItisknowntoallthatChinahasjoinedtheWTO.（主語從句，it做形式主語）Asisknowntoall,ChinahasjoinedtheWTO.（as引導的非限制性定語從句）WhatisknowntoallisthatChinahasjoinedtheWTO.（主語從句和表語從句）四、it的問題1.it做形式主語（注意與強調句式的辨別）.ItwasmyfaultthatIhadhimplayfootballallafternoon. Itisimportantthatweshouldgototheschooltotalkwiththeteacher.2.it做形式賓語---V+it+adj./n.+todo/賓從(V可以為make,find,feel,think,believe,consider,guess,suppose等).Ithinkitnecessarythatwetake
