高中英語必修三名詞性從句綜合詳細講解與練習

PAGEPAGE4名詞性從句知識點在復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。名詞性從句是中學階段的一個重要語法項目，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疑問詞+ever引導的名詞性從句與nomatter+疑問詞引導的狀語從句的區(qū)別 6.考查名詞性從句的虛擬語氣問題

語法要點剖析

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，相當于一個名詞。因此，這四種從句通稱為名詞性從句。

引導名詞性從句的連接詞可分為三類：

連接詞：that,whether,if（不充當從句的任何成分）

連接代詞：what,whatever,who,whoever,whom,whose,which.

連接副詞：when,where,how,why

1.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。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，在從句中充當從句的成分。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）It+be+名詞+that從句 （2）It+be+形容詞+that從句

（3）It+be+動詞的過去分詞+that從句 （4）It+不及物動詞+that從句另注意在主語從句中用來表示驚奇、不相信、惋惜、理應如此等語氣時，謂語動詞要用虛擬語氣“(should)+do”，常用的句型有：

Itisnecessary(important,natural,strange,etc.)that…

Itisapity(ashame,nowonder,etc.)that…

Itissuggested(requested,proposed,desired,etc.)that…2.賓語從句名詞句用作賓語的從句叫賓語從句。引導賓語從句的關聯(lián)詞與引導主語從句表語從句的關聯(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that引導的賓語從句由連接詞that引導賓語從句時，that在句中不擔任任何成分，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：

HehastoldmethathewillgotoShanghaitomorrow. 他已經(jīng)告訴我他明天要去上海。

Wemustneverthink(that)wearegoodineverythingwhileothersaregoodinnothing.我們決不能認為自己什么都好，別人什么都不好。

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)doherworkalone. 我堅持要她自己工作。

Thecommanderorderedthattroops(should)setoffatonce. 司令員命令部隊馬上出發(fā)。

2.用who，whom,which,whose,what,when,where,why,how,whoever,whatever,whichever等關聯(lián)詞引導的賓語從句相當于特殊疑問句，應注意句子語序要用陳述語序。例如： Iwanttoknowwhathehastoldyou.我想知道他告訴了你什么。

Shealwaysthinksofhowshecanworkwell.她總是在想怎樣能把工作做好。

Shewillgivewhoeverneedshelpawarmsupport.凡需要幫助的人，她都會給予熱情的支持。

3.用whether或if引導的賓語從句，其主語和謂語的順序也不能顛倒，仍保持陳述句語序。此外，whether與if在作“是否”的意思講時在下列情況下一般只能用whether，不用if：

a.引導主語從句并在句首時；b.引導表語從句時；c.引導從句作介詞賓語時；d.從句后有“ornot”時；e.后接動詞不定式時。例如： Whetherthereislifeonthemoonisaninterestingquestion.月球上有沒有生命是個有趣的問題。

Everythingdependsonwhetherwehaveenoughmoney.一切要看我們是否有足夠的錢。

4.注意賓語從句中的時態(tài)呼應，當主句動詞是現(xiàn)在時，從句根據(jù)自身的句子情況，而使用

不同時態(tài)。例如： hestudiesEnglisheveryday.（從句用一般現(xiàn)在時）

hestudiedEnglishlastterm.（從句用一般過去時）

Iknow(that)hewillstudyEnglishnextyear.（從句用一般將來時）

hehasstudiedEnglishsince1998.（從句用現(xiàn)在完成時）當主句動詞是過去時態(tài)（could,would除外），從句則要用相應的過去時態(tài)，如一般過去時，過去進行時，過去將來時等；當從句表示的是客觀真理，科學原理，自然現(xiàn)象，則從句仍用現(xiàn)在時態(tài)。例如：TheteachertoldusthatTomhadleftusforAmerica．

5.think,believe,imagine,suppose等等動詞引起的否定性賓語從句中，要把上述主句中的動詞變?yōu)榉穸ㄊ?。即將從句中的否定形式移到主句中。例如?Wedon’tthinkyouarehere.我們認為你不在這。

Idon’tbelievehewilldoso.我相信他不會這樣做。

3.表語從句在句中作表語的從句叫表語從句。引導表語從句的關聯(lián)詞與引導主語從句的關聯(lián)詞大致一樣，表語從句位于連系動詞后，有時用asif引導。其基本結構為：主語+系動詞+that從句。例如：

Thefactisthatwehavelostthegame. 事實是我們已經(jīng)輸了這場比賽。

Thatiswhyhedidn’tcometothemeeting. 那就是他為什么不到會的原因。

Itlooksasifitisgoingtorain. 看上去天要下雨了。

需要注意的，當主語是reason時，表語從句要用that引導而不是because。例如：

Thereasonwhyhewaslatewasthathemissedthetrainbyoneminutethismorning4.同位語從句同位語從句說明其前面的名詞的具體內容。同位語從句通常由that引導，可用于同位語從句的名詞有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如：

Thenewsthatwewonthegameisexciting.我們贏得這場比賽的消息令人激動。

Ihavenoideawhenhewillcomebackhome.我不知道他什么時候回來。

ThethoughtcametohimthatMaryhadprobablyfallenill.他想到可能瑪麗生病了。

同位語從句和定語從句的區(qū)別：that作為關系代詞，可以引導定語從句，充當句子成分，在從句中作賓語時可以省略；that引導同位語從句時，起連詞的作用，沒有實際意義，不充當句子成分，一般不能省略。
