名詞性從句講解及專項(xiàng)練習(xí)習(xí)題及其解答

1、1名詞性從句講解名詞性從句講解在復(fù)合句中起名詞作用的從句叫做名詞性從句。它包括主語從句、賓語從句、表語從句和同位語從句。名詞性從句是中學(xué)階段的一個重要語法項(xiàng)目，在歷年的高考中幾乎都涉及到，并且每年的命題各有變化。分析歷屆高考試題名詞性從句考查的焦點(diǎn)主要有以下六個方面1.考查名詞性從句的語序問題2.考查引導(dǎo)詞that與what的區(qū)別3.考查it在名詞性從句中作形式主語或形式賓語的用法4.考查whether與if的區(qū)別5.考查名詞性從句中的

2、疑問詞ever引導(dǎo)的名詞性從句與nomatter疑問詞引導(dǎo)的狀語從句的區(qū)別6.考查名詞性從句的虛擬語氣問題語法要點(diǎn)剖析語法要點(diǎn)剖析一、名詞性從句一、名詞性從句主語從句、表語從句、賓語從句、同位語從句，在整個句子中所起的作用，相當(dāng)于一個名詞。因此，這四種從句通稱為名詞性從句。引導(dǎo)名詞性從句的連接詞可分為三類：引導(dǎo)名詞性從句的連接詞可分為三類：連接詞：連接詞：thatwhetherif（不充當(dāng)從句的任何成分）連接代詞：連接代詞：whatwh

3、ateverwhowhoeverwhomwhosewhich.連接副詞：連接副詞：whenwherehowwhy1.主語從句主語從句作句子主語的從句叫主語從句。主語從句通常由從屬連詞that，whether，if和連接代詞what，who，which，whatever，whoever以及連接副詞how，when，where，why等詞引導(dǎo)。that在句中無詞義，只起連接作用；連接代詞和連接副詞在句中既保留自己的疑問含義、又起連接作用，在

4、從句中充當(dāng)從句的成分。例如：Whathewantstotellusisnotclear.他要跟我們說什么，還不清楚。Itisknowntoushowhebecameawriter.我們都知道他是如何成為一名作家的。WheretheEnglisheveningwillbeheldhasnotyetbeenannounced.英語晚會將在哪里舉行，還沒有宣布。有時為避免句子頭重腳輕，常用形式主語it代替主語從句作形式主語放于句首，而把主語從

5、句置于句末。主語從句后的謂語動詞一般用單數(shù)形式。常用句型如下：（1）Itbe名詞名詞that從句從句（2）Itbe形容詞形容詞that從句從句（3）Itbe動詞的過去分詞動詞的過去分詞that從句從句（4）It不及物動詞不及物動詞that從句從句另注意在主語從句中用來表示驚奇、不相信、惋惜、理應(yīng)如此等語氣時，謂語動詞要用虛擬語氣“(should)do”，常用的句型有：Itisnecessary(imptantnaturalstrange

6、etc.)that…Itisapity(ashamenowonderetc.)that…Itissuggested(requestedproposeddesiredetc.)that…2.賓語從句賓語從句名詞句用作賓語的從句叫賓語從句。引導(dǎo)賓語從句的關(guān)聯(lián)詞與引導(dǎo)主語從句表語從句的關(guān)聯(lián)詞大致一樣，在句中可以作謂語動詞或介詞及非謂語動詞的賓語。1.由連接詞由連接詞that引導(dǎo)的賓語從句引導(dǎo)的賓語從句由連接詞that引導(dǎo)賓語從句時，that在

7、句中不擔(dān)任任何成分，在口語或非正式的文體中常被省去，但如從句是并列句時第二個分句前的that不可省。例如：HehastoldmethathewillgotoShanghaitomrow.他已經(jīng)告訴我他明天要去上海。Wemustneverthink(that)wearegoodineverythingwhileothersaregoodinnothing.我們決不能認(rèn)為自己什么都好，別人什么都不好。注意：注意：在dem、der、sugge

8、st、decide、insistdesiredemrequestcomm等表示要求、命令、建議、決定等意義的動詞后，賓語從句常用“（should）動詞原形”。例如：Iinsistthatshe(should)doherwkalone.我堅(jiān)持要她自己工作。Thecommerderedthattroops(should)setoffatonce.司令員命令部隊(duì)馬上出發(fā)。2.用who，whomwhichwhosewhatwhenwherewh

9、yhowwhoeverwhateverwhichever等關(guān)聯(lián)詞引導(dǎo)的賓語從等關(guān)聯(lián)詞引導(dǎo)的賓語從句相當(dāng)于特殊疑問句，應(yīng)注意句子語序要用陳述語序。句相當(dāng)于特殊疑問句，應(yīng)注意句子語序要用陳述語序。3A.fromwhatcitydoesshecomefromB.fromwhatcityshecomeC.whatcitydoesshecomefromD.whatcityshecomesfrom3.________makesmistakesmus
