第一篇：that在名詞性從句中的用法歸納

what 在名詞性從句中的用法

1．確定含義。what 引導(dǎo)名詞性從句有兩種含義：（1）什么（2）……的人/事/物。例如：

1.I don't know what I should do with the problems.我不知道該如何處理這些問題。（什么）

2.What you will do next is none of my business.你下一步做什么不關(guān)我的事。（什么）3.The teacher told us he wanted to take back what he had said.老師告訴我們他想收回他說過的話。（……的話）

4.She is no longer what she used to be.她不是過去的她了。（……的人）2． 確定成分。what 作“什么”講，在名詞性從句中作主語、賓語、表語或定語；作“……的人/事/物”講，在名詞性從句中作主語、賓語或表語。例如： 5.They don't know what happened.他們不知道發(fā)生了什么。（what 在從句中作主語，含義是“什么”）

6.What he says is not important.他所說的并不重要。（what 在從句中作主語，含義是“……的話”）

7.Do what you please.你愛干什么就干什么。（what 在從句中作賓語，含義是“……的事“）

8.Please tell me what you are doing here on earth!請告訴我你究竟在這里干什么?。╳hat 在從句中作賓語，含義是“什么”）

9.He is not what he was ten years ago.他不再是十年前的他了。(what 在從句中作表語，含義是“……人”)

10.It is the ability to do the job, not what she is , that matters.重要的是（她）做這項工作的能力，而不是她是什么（人）。（what 在從句中作表語，含義是“什么”）

11.Are you sure what books he likes reading? 你知道他喜歡讀什么書嗎？（what 在從句中作定語，含義是“什么”）

注：what 作“……的人/事/物”講時一般不作定語。

3．引導(dǎo)從句的性質(zhì)。what 可以引導(dǎo)主語從句(例句 2 和例句 6)、賓語從句（例句 1 和例句 3）、表語從句（例句 4 和例句 9）、同位語從句。再如：

The question what makes the matter worse has been puzzling me.是什么使情況更糟了？這個問題一直在困惑著我。（what 引導(dǎo)的是同位語從句）注：除了上述主要用法外，what 還有兩種其它用法。

a.關(guān)系形容詞用法：作定語，意為：所……的，任何……的（= as much/many as；the...that；any...that）。例如：

I gave him what books(=any books that/the books that)I had.我把我所有的書全給他了。

I will give you what help(=any help that/as much help as)I can.我愿盡力幫助你。Lend me what money(= as much money as)you can.你能借多少錢就借給我多少。b.感嘆詞用法：作定語，意為：多么（多用于簡單句中的感嘆句中）What a fool you are!你多傻！What a good idea!多妙的主意??！What happy boys!多幸福的孩子??！What a pity!真遺憾！

What 和that 在名詞性從句中的用法區(qū)別

名詞性從句包括主語從句、賓語從句、表語從句、同位語從句四種。名詞性從句是高二學(xué)生必學(xué)的重要英語語法之一。在學(xué)名詞性從句時，學(xué)生經(jīng)常為What 和that 在句中的用法而困惑。下面是我在教學(xué)實踐中對這一知識的總結(jié)，僅供同學(xué)們參考：

What 和that 都可以引導(dǎo)名詞性從句。但他們在句子中的語法功能截然不同。一．在引導(dǎo)名詞性從句時，從屬連詞that一般要注意三個不（three nos）： 1．不省略（no ellipsis）

當(dāng)從屬連詞that引導(dǎo)主語從句、表語從句和同位語從句時，that不省略。

Eg.1)That he was able to come made us happy.(That 引導(dǎo)主語從句不可省略)2)The truth is that I didn’t go there.(that引導(dǎo)表語從句不可省略)

3)The news that our team has won is true.(that引導(dǎo)同位語從句不可省略)但在非正式文體中that 引導(dǎo)賓語從句時可以省略，除下列兩種情況外： that在賓語從句中不能省略的情況.(1).在主+謂+it(形式賓語)+賓補+that，從句(真正賓語)的句型中不省略.Eg: 4)He made it quite clear that he preferred to study English.（that不可以省略）

他很明確地說他寧愿學(xué)習(xí)英語。

(2).由連詞and連接的兩個由that引導(dǎo) 的賓語從句中, 則第二個賓語從句前的that不省略。

Eg: 5)He told me that he would come and that he would come on time.（第一個That可以省略，但第二個that不可以省略。)他告訴我他將來而且他將準(zhǔn)時來。

2．不作成分（no component）

that 在名詞性從句中不作任何句子成分。

Eg.6)Sydney kept his promise that he would always do anything he could for Lucie to make sure of her happiness.（that在句中引導(dǎo)同位語從句，但在句中不作任何成分）

7))That you don’t like him is none of my business.(that在句中引導(dǎo)主語從句，但在句中不作任何成分，也不省略）

3． 沒詞義（no meaning）

that 在名詞性從句中沒有漢語意思。

Eg.8)That she is a rich woman is known to us.(that在句中引導(dǎo)主語從句，但在句中沒有漢語意義)

她是一個很有錢的女子，這一點我們都知道。

9）The thought that he might fail in the exam worried him.(that在句中引導(dǎo)同位語從句，但在句中沒有漢語意義）

他也許會考試失敗，這一想法使他很擔(dān)心。

第二篇：名詞性從句的用法

名詞性從句的用法

在句子中起名詞作用的句子叫名詞從句(Noun Clauses）。名詞從句的功能相當(dāng)于名詞詞組, 它在復(fù)合句中能擔(dān)任主語、賓語、表語、同位語、介詞賓語等，因此根據(jù)它在句中不同的語法功能，名詞從句又可分別稱為主語從句、賓語從句、表語從句和同位語從句。

一、引導(dǎo)名詞性從句的連接詞

引導(dǎo)名詞性從句的連接詞可分為三類：連詞：that（無任何詞意）；whether, if（均表示“是否”表明從句內(nèi)容的不確定性）；as if ,as though（均表示“好像”，“似乎”）。以上在從句中均不充當(dāng)任何成分

連接代詞：what, whatever, who, whoever, whom, whose, which.Whichever, whomever 連接副詞：when, where, how, why 不可省略的連詞： 1.介詞后的連詞

2.引導(dǎo)主語從句和同位語從句的連詞不可省略。That she was chosen made us very happy.We heard the news that our team had won.比較：

Whether與if 均為“是否”的意思。但在下列情況下，whether 不能被if 取代： 1.Whether引導(dǎo)主語從句并在句首； 2.引導(dǎo)表語從句

3.Whether從句作介詞賓語； 4.從句后有“or not”

Whether he will come is not clear.大部分連接詞引導(dǎo)的主語從句都可以置于句末，用 it充當(dāng)形式主語。It is not important who will go.It is still unknown which team will win the match.二、具體分類 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(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，在從句中充當(dāng)從句的成分。例如：

What he wants to tell us is not clear.他要跟我們說什么，還不清楚。Who will win the match is still unknown.誰能贏得這場比賽還不得而知。It is known to us how he became a writer.我們都知道他是如何成為一名作家的。Where the English evening will be held has not yet been announced.英語晚會將在哪里舉行，還沒有宣布。

【典例1】(2009·上海卷)It is immediately clear ____ the financial crisis will soon be over.A.since B.what C.when D.whether 【答案】D

【解析】考查主語從句的用法。該句的意思時：經(jīng)濟危機是否會很快結(jié)束是很明顯的事情?！笆?1 否”用whether表示，不能選when是因為從句中由soon這一實踐狀語。

【典例2】(2008·山東卷)_____ was most important to her, she told me, was her family.A.It B.This C.What D.As 【答案】C

【解析】she told me是插入語，可刪除。what引導(dǎo)主語從句，在從句中充當(dāng)主語。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(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：

It is necessary(important, natural, strange, etc.)that … It is a pity(a shame, no wonder, etc.)that…

It is suggested(requested, proposed, desired, etc.)that…

【典例】(2009·天津卷)It is obvious to the students ______ they should get well prepared for their future.A.as B.which C.whether D.that 【答案】D

【解析】考查名詞性從句。本空格處應(yīng)是一個主語從句的引導(dǎo)詞，因該主語從句不缺成分，且句意完整，故應(yīng)用不作任何成分的連詞that。2．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that引導(dǎo)的賓語從句

由連接詞that引導(dǎo)賓語從句時，that在句中不擔(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：

He has told me that he will go to Shanghai tomorrow.他已經(jīng)告訴我他明天要去上海。We must never think(that)we are good in everything while others are good in nothing.我們決不能認(rèn)為自己什么都好，別人什么都不好。

注意：在demand，order，suggest，decide，insist，desire，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： I insist that she(should)do her work alone.我堅持要她自己工作。

The commander ordered that troops(should)set off at once.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(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。例如： I want to know what he has told you.我想知道他告訴了你什么。

She always thinks of how she can work well.她總是在想怎樣能把工作做好。

She will give whoever needs help a warm support.凡需要幫助的人，她都會給予熱情的支 2 持。

【典例1】(2008·北京卷)The companies are working together to create _______ they hope will be the best means of transport in the 21st century.A.which B.that C.what D.who 【答案】C

【解析】create后為賓語從句，從句中they hope是插入語，可刪除。因為從句中缺少主語，所以用what引導(dǎo)該從句。

【典例2】(2009· 全國卷Ⅰ)Could I speak tois in charge of International Sales please? A.who B.what C.whoever D.whatever 【答案】C

【解析】 考查名詞性從句。題干中介詞to后面為賓語從句，從句中缺少主語，因此填whoever。（3）用whether或if引導(dǎo)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(dǎo)主語從句并在句首時；b.引導(dǎo)表語從句時；c.引導(dǎo)從句作介詞賓語時；d.從句后有“or not”時；e.后接動詞不定式時。例如：

Whether there is life on the moon is an interesting question.月球上有沒有生命是個有趣的問題。

The question is whether she should have a low opinion of the test?

Everything depends on whether we have enough money.一切要看我們是否有足夠的錢。I wonder whether he will come or not.我想知道他來還是不來。Can you tell me whether to go or to stay? 你能否告訴我是去還是留？

（4）注意賓語從句中的時態(tài)呼應(yīng)，當(dāng)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：

he studies English every day.（從句用一般現(xiàn)在時）he studied English last term.（從句用一般過去時）

I know(that)he will study English next year.（從句用一般將來時）he has studied English since 1998.（從句用現(xiàn)在完成時）

當(dāng)主句動詞是過去時態(tài)（could, would除外），從句則要用相應(yīng)的過去時態(tài)，如一般過去時，過去進行時，過去將來時等；當(dāng)從句表示的是客觀真理，科學(xué)原理，自然現(xiàn)象，則從句仍用現(xiàn)在時態(tài)。例如：

The teacher told us that Tom had left us for America．

（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?We don’t think you are here.我們認(rèn)為你不在這。I don’t believe he will do so.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(dǎo)表語從句的關(guān)聯(lián)詞與引導(dǎo)主語從句的關(guān)聯(lián)詞大致一樣，表語從句位于連系動詞后，有時用as if引導(dǎo)。其基本結(jié)構(gòu)為：主語 + 系動詞 + that從句。例如：

The fact is that we have lost the game.事實是我們已經(jīng)輸了這場比賽。

That’s just what I want.這正是我想要的。

This is where our problem lies.這就是我們的問題所在。

That is why he didn’t come to the meeting.那就是他為什么不到會的原因。It looks as if it is going to rain.看上去天要下雨了。

需要注意的，當(dāng)主語是reason時，表語從句要用that引導(dǎo)而不是because。例如： The reason why he was late was that he missed the train by one minute this morning.【點撥】whether 可引導(dǎo)表語從句，但與之同義的if卻通常不用于引導(dǎo)表語從句。

【典例1】(2009·山東卷)The little girl who got lost decided to remain ________she was and wait tor her mother.A.where B.what C.how D.who 【答案】A

【解析】remain是系動詞，后加表語從句，由句意可知，從句缺地點狀語，所以選A?！镜淅?】(2008·天津卷)The last time we had grat fun was _______ we were visiting the Water Park.A.where B.how C.when D.why 【答案】C

【解析】was后為表語從句，此處when與the last time相呼應(yīng)，根據(jù)句意可排除其他選項。4． 同位語從句

同位語從句說明其前面的名詞的具體內(nèi)容。同位語從句通常由that引導(dǎo)，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：

The news that we won the game is exciting.我們贏得這場比賽的消息令人激動。I have no idea when he will come back home.我不知道他什么時候回來。

The thought came to him that Mary had probably fallen ill.他想到可能瑪麗生病了?！镜淅?2009· 重慶卷)We should consider the students’ request ________ the school library provide more books on popular science.A.that B.when C.which D.where 【答案】A

【解析】考查名詞性從句。根據(jù)題意知，空格處是同位語從句的引導(dǎo)詞，修飾中心名詞request，且在句子中不充當(dāng)成分，故用that。這句話的意思是我們應(yīng)該考慮學(xué)生的這個要求，即學(xué)校圖書館應(yīng)該多提供一些大眾科學(xué)方面的書籍。

三、對比與用法

1．同位語從句和定語從句的區(qū)別：

that作為關(guān)系代詞，可以引導(dǎo)定語從句，充當(dāng)句子成分，在從句中作賓語時可以省略； that引導(dǎo)同位語從句時，起連詞的作用，沒有實際意義，不充當(dāng)句子成分，一般不能省略。試比較下面兩個例句:

I had no idea that you were here．（that引導(dǎo)同位語從句，不能省略）

Have you got the idea（that）this book gives you of life in ancient Greece？（that引導(dǎo)定語從句，作賓語，可以省略）

2．that-從句作主語通常用it作先行詞，而將that-從句置于句末。

用it作形式主語的that-從句有以下四種不同的搭配關(guān)系： a.It + be +形容詞+ that-從句 It is necessary that… 有必要…… It is important that… 重要的是…… It is obvious that… 很明顯…… b.It + be +-ed 分詞+ that-從句 It is believed that… 人們相信…… It is known to all that… 從所周知…… It has been decided that… 已決定…… c.It + be +名詞+ that-從句

It is common knowledge that… ……是常識 It is a surprise that… 令人驚奇的是…… It is a fact that… 事實是…… d.It +不及物動詞+ that-分句 It appears that… 似乎…… It happens that… 碰巧……

It occurred to me that… 我突然想起……

It is quite clear that the whole project is doomed to failure.很清楚，整個計劃注定要失敗。

It's a pity that you should have to leave.你非走不可真是件憾事。3．否定轉(zhuǎn)移

（1）將think, believe, suppose, expect, fancy, imagine等動詞后面賓語從句的否定詞轉(zhuǎn)移到主句中，即主句的謂語動詞用否定式，而從句的謂語動詞用肯定式。I don't think I know you.我想我并不認(rèn)識你。I don' t believe he will come.我相信他不回來。注意：若謂語動詞為hope,賓語從句中的否定詞不能轉(zhuǎn)移。I hope you weren't ill.我想你沒有生病吧。

（2）將seem, appear 等后的從句的否定轉(zhuǎn)移到前面。It doesn't seem that they know where to go.看來他們不知道往哪去。

It doesn't appear that we'll have a sunny day tomorrow.看來我們明天不會碰上好天氣?！緜淇疾呗浴?/p>

考生對于名詞性從句的復(fù)習(xí)和應(yīng)試關(guān)鍵要把握每個引導(dǎo)詞的意義，因為在對于名詞性從句的考查中，引導(dǎo)詞在句子中都起作用，有意義，因此在分析句子結(jié)構(gòu)，對比辨別名詞性從句、狀語從句、強調(diào)句式后，最后還是要選擇引導(dǎo)詞；另外還要注意以下幾點：

1．what 引導(dǎo)詞的考查，尤其位于介詞后引導(dǎo)的賓語從句以及引導(dǎo)名詞性從句時的雙重作用。2．Whether和if 的區(qū)別，尤其注意他們的不同之處。

3．名詞性從句和其它從句的兼容結(jié)構(gòu)測試。4.句子語序和時態(tài)。具體說：

1.掌握名詞性從句的分類功能

名詞性從句根據(jù)其在主句的功能作用又可分為主語從句、賓語從句、表語從句和同位語從句。(1)若從句在句中作主語為主語從句(2)若從句在句中作賓語為賓語從句(3)若從句在句中作表語為表語從句(4)若從句在句中作同位語為同位語從句 2.掌握連詞的含義及分類

絕大多數(shù)名詞性從句的連詞都有其實在意義，稱為有義連詞，如what表“……的內(nèi)容”，when表“……的時間”，where表“……的地點”，why表“……的原因”，how表“如何；怎樣”，who表“誰”，if, whether表“是否”；沒有實在意義的連詞叫無義連詞，無義連詞只有that一個。

3.掌握名詞性從句的語序 名詞性從句用陳述語序。

4.掌握名詞性從句和其它從句之間的關(guān)系

有些連詞除引導(dǎo)名詞性從句外還可引導(dǎo)其它從句，應(yīng)掌握它們之間的關(guān)系。

(1)if ,whether表“是否”時引導(dǎo)名詞性從句；if表“如果”時引導(dǎo)條件狀語從句；whether表“無論是否；不管是否”時引導(dǎo)讓步狀語從句。

(2)when表“……的時間”，where表“……的地方”時引導(dǎo)名詞從句；when表“當(dāng)……的時候”引導(dǎo)時間狀語從句，where表“……的地方”，且修飾行為動詞時，引導(dǎo)地點狀語從句；when, where從句作定語修飾先行詞時引導(dǎo)定語從句?！緦ｎ}突破】

高考中考查名詞性從句時，經(jīng)常考查連接詞的選用。解題時應(yīng)先判斷從句的類型，然后判斷從句是否缺少成分以及意義是否完整，最后根據(jù)引導(dǎo)名詞性從句的連詞的特點確定特定的連接詞。要求學(xué)生在做題中要注意如下幾點： 1.分析結(jié)構(gòu)，辨析名詞性從句和狀語從句； 2.理解句意，正確區(qū)別引導(dǎo)詞；

3.按照句意，出現(xiàn)那個引導(dǎo)詞意思，便選擇那個引導(dǎo)詞?！緦ｎ}鞏固】

1.C 句意：我腦海中突然出現(xiàn)一個溫情的念頭，用我的零花錢給媽媽買些鮮花作為她的生日禮物。本題考察名詞性從句用法。I might use the pocket money to buy some flowers for my mother’s birthday.做A warm thought 的同位語從句。中間被suddenly came to me隔開，增加了試題難度。此外，部分考生由于對同位語從句和定語從句不分，故錯選D為答案。2.D 表語從句中缺did的賓語。

3.A “_______is still a wasteland now.”做介詞in的賓語從句，從句中缺主語句意為：政府已經(jīng)宣布一座現(xiàn)代化的城市將在這片現(xiàn)在仍是廢墟的地方建成。

4.A“_______Liu Xiang had failed to compete in the event.”做介詞on的賓語，賓語從句中不缺主干，故排除B和C。另外that不引導(dǎo)介詞的賓語從句（固定搭配除外），所以排除D。5.B “_______is described as one of the most beautiful islands.”賓語從句，從句中缺少主語，6.B whoever在賓語從句中做主語，部分學(xué)生，因為只看到介詞to，誤認(rèn)為要添whomever做介詞的賓語。

7.B “_______it takes to keep a nation highly competitive.”做表語從句，從句中缺少takes的賓語，構(gòu)成 it takes sth to do sth 結(jié)構(gòu)。

8.A本題句子結(jié)構(gòu)比較復(fù)雜，“_______ a nation loses in times of disaster will be made up for by her progress”做a truth的同位語從句，同位語從句中_______ a nation loses in times of disaster為主語從句。本句共有兩個從句，故有兩個引導(dǎo)詞。句意為“中華民族的經(jīng)驗證明了一個真理，即，一個民族在災(zāi)難中失去的，必將從民族的進步中得到補償。

9.C “_______has recently been done to provide more buses for the people”在句中做讓步狀語,而D.Though what錯誤, 因為, 一個單一的從句不能用兩個連詞引導(dǎo).句意: 盡管在為人們提供更多公交車這件事上, 投入了很多, 但是公交工具的缺乏, 仍然是個問題.10.B “_______is certain”在句中做主語,主語從句缺少一個主語,需要用What;“_______prevention is more important than treatment.”系表語從句,句意與結(jié)構(gòu)完整,只有that,可以這樣用。

11.A“_______ they lost the game.”在句子中做the fact 的同位語從句,從句意思結(jié)構(gòu)完整,結(jié)構(gòu)完整。

12.C先將句子結(jié)構(gòu)理清楚，it is _______that has made him _______he is today 就可以判斷，第一個空是考察強調(diào)句型的特殊疑問形式；第二個空則是表語從句，表語從句中缺少he is的表語。句意：病人好多了，是什么使得他成為現(xiàn)在這個樣子。

13.A考生誤以為是地點狀語從句，誤選C．where。而reached是及物動詞，后邊接的是賓語從句，賓語從句除去插入語they thought，應(yīng)該缺主語。

14.B 考察同位語從句，表達(dá)A plan的具體內(nèi)容，has been put forward將名詞與從句隔開，8 加大了難度。

15.C 主要測試主語從句。分析句子結(jié)構(gòu)可知：句子屬于形式主語格式；另外主句中缺少主語。雙重作用的引導(dǎo)詞只能是what。例如：It is still doubtful what he said at the meeting yesterday。昨天他在會上說的話仍然值得懷疑。

16.C 名詞性從句的引導(dǎo)詞。句意為：她對我們來說是非常寶貴，我們已經(jīng)準(zhǔn)備好做一切來拯救她的生命。

17.D 此處從句作介詞to的賓語，是名詞性從句，引導(dǎo)詞作從句的主語，指人，意思是：無論是誰，選D。

18.C 考查名詞性從句，介詞from后除了接代詞或名詞作賓語外，還可接介詞短語或副詞短語作賓語；由后面“I was born”可以推測from后面可以指時間，也可以指地點，再由所給的選項可得出答案。

19.D 考查名詞性從句。賓語從句中缺少主語，因此選what。

20.B考查同位語從句。此處是由what引導(dǎo)的同位語從句，表示“你有沒有可能來機場接我？”。所以選B項。

第三篇：名詞性從句 同位語從句用法詳解

名詞性從句 同位語從句用法詳解(例句豐富)

一、同位語從句的引導(dǎo)詞

引導(dǎo)同位語從句的詞語通常有連詞that，whether，連接代詞和連接副詞等。

1.由that引導(dǎo)

We heard the news that our team had won.我們聽到消息說我們隊贏了。

They were worried over the fact that you were sick.他們?yōu)槟闵“l(fā)愁。

The news that we are having a holiday tomorrow is not true.明天放假的消息不實。

I’ve come to the conclusion that it was unwise to do that.我得出結(jié)論這樣做是不明智的。

The fact that the money has gone does not mean it was stolen.那筆錢不見了這一事實并不意味著是被偷了。

He referred to Copernicus’ statement that the earth moves round the sun.他提到了哥白尼關(guān)于地球繞太陽轉(zhuǎn)的說法。

【注意1】在某些名詞(如demand, wish, suggestion, resolution等)后面的同位語從句要用虛擬語氣。如：

They were faced with the demand that this tax be abolished.他們面對廢除這個稅的要求。

They expressed the wish that she accept the award.他們表示希望她接受這筆獎金。

There was a suggestion that Brown should be dropped from the team.有一項建議是布朗應(yīng)該離隊。

The suggestion that the new rule be adopted came from the chairman.采納新規(guī)則的建議是主席提出的。The resolution that women be allowed to join the society was carried.允許婦女參加這個協(xié)會的決議通過了。

I can understand their eagerness that you should be the main speaker.我理解他們希望你作主要發(fā)言人的殷切心情。

【注意2】引導(dǎo)同位語從句的連詞that通常不省略，但在非正式文體中也可以省去。如：

He gabbed his suitcase and gave the impression he was boarding the Tokyo plane.他拿起了手提箱，給人的印象是他要登上飛往東京的飛機了。

2.由whether引導(dǎo)

There is some doubt whether he will come.他是否會來還不一定。

Answer my question whether you are coming.你回答我的問題：你來不來。

The question whether it is right or wrong depends on the result.這個是對還是錯要看結(jié)果。

We are not investigating the question whether he is trustworthy.我們不是在調(diào)查他是否可以信任的問題。

【注意】whether 可引導(dǎo)同位語從句，但if不能引導(dǎo)同位語從句。

3.由連接代詞引導(dǎo)

Have you any idea what time it starts? 你知道什么時候開始嗎?

From 1985-90 I was an instructor at the regional party headquarters.After that I went back to work in a factory.Then I had no idea what a casino was.從1985年到1990年我是地方黨部的教員。隨后我回到一家工廠工作。當(dāng)時我不知道賭場是什么樣的地方。

4.由連接副詞引導(dǎo)

I have no idea when he will come back.我不知道他什么時候回來。It is a question how he did it.那是一個他如何做的問題。

He had no idea why she left.他不知道她為什么離開。

You have no idea how worried I was!你不知道我多著急!

二、關(guān)于分離同位語從句

有時同位語從句可以和同位的名詞分開。如：

The story goes that he beats his wife.傳說他打老婆。

The news got about that he had won a car in the lottery.消息傳開說他中彩得了一輛汽車。

The rumour spread that a new school would be built here.謠傳這里要蓋一所新學(xué)校。

Report has it that the Smiths are leaving town.有傳言說史密斯一家要離開這座城市。

The thought came to him that maybe the enemy had fled the city.他想到可能敵人已逃離這座城市。

The order soon came that all citizens should evacuate the village.不久命令下來，所有居民都必須撤出村子。(G31)

二、同位語從句與定語從句的區(qū)別

1．意義的不同

同位語從句是用于說明所修飾名詞的具體內(nèi)容的，它與被修飾詞語通?？梢詣澋忍枺欢ㄕZ從句是限制所修飾名詞的，它的作用是將所修飾的名詞與其他類似的東西區(qū)別開來：

We are glad at the news that he will come.聽到他要來這個消息我們很高興。(news的內(nèi)容就是that he will come，故that引導(dǎo)的是同位語從句)

We are glad at the news that he told us.聽到他告訴我們的這個消息我們很高興。(that從句是限制the news的內(nèi)容的，即我們高興只是因為他告訴的這個news而不是其他的news，故that從句為定語從句)2.引導(dǎo)詞的不同

what, how, if, whatever 等可引導(dǎo)名詞性從句，但不引導(dǎo)定語從句。

3.引導(dǎo)詞的功能上的不同

that引導(dǎo)同位語從句時，它不充當(dāng)句子成分，而引導(dǎo)定語從句時，它作為關(guān)系代詞，要么充當(dāng)定語從句的主語，要么充當(dāng)定語從句的賓語。如上例 that he told us中的that就充當(dāng)told的賓語。

4.被修飾詞語的區(qū)別

同位語從句所修飾的名詞比較有限，通常有hope, wish, idea, news, fact, promise, opinion, suggestion, truth等，而定語從句所修飾的名詞則非常廣泛。另外，when和where 引導(dǎo)定語從句時，通常只修飾表示時間和地點的名詞，而它們引導(dǎo)同位語從句時卻不一定；又如why引導(dǎo)定語從句，它通常只修飾名詞the reason，而它引導(dǎo)同位語從句時則不一定：

I have no idea when they will come.我不知道他們什么時候來。(同位語從句)

I’ll never forget the days when I lived there..我永遠(yuǎn)不會忘記我住在那兒的日子。(定語從句)

We don’t understand the problem why this is the best choice.我們不明白這個問題，為什么這是最好的選擇。(同位語從句)

The reason why he didn’t come to the meeting is that he is ill.他未能來開會，原因是他生病了。(定語從句)

第五篇：名詞性從句

名詞性從句

名詞性從句相當(dāng)于名詞，可分別作主句的主語、表語、賓語和同位語。因此，名詞性從句廳分為主語從句、表語從句、賓語從句和同位從句。一．引導(dǎo)名詞性從句的連接詞

1、連接代詞：who, whose, whom, what, which。有詞義，在從句中擔(dān)任成分，如主語、表語、賓語、或定語等。

2、連接副詞：when, where, why, how。有詞義，在從句中擔(dān)任成分，作狀語。

3、連接詞：that, whether, if, as if。that 無詞義，在從句中不擔(dān)任成分，有時可省略；if(whether), as if雖有詞義，但在從句中不擔(dān)任成分。

注意：連接代詞與連接副詞在句中不再是疑問句，因而從句中謂語不用疑問式。連接代詞與連接副詞在從句充當(dāng)句子成分，連接詞whether 和if（是否），as if（好象）在從句中不充當(dāng)句子成分，只起連接作用。根據(jù)句義，如果連接代詞與連接副詞，whether、if 和as if都用不上時，才用that作連接詞（that本身無任何含義）。二.名詞性從句的分類如下

（一）主語從句

主語從句的句型.引導(dǎo)詞有疑問詞wh-及whether/if及that.1、主語從句在復(fù)合句作主語。疑問詞引導(dǎo)e.g.Who will go is not important.2、用it作形式主語，主語從句放在句末。

3、If/whether 引導(dǎo)e.g.It doesn’t matter so much whether you will come or not.4．It+be+adj(obvious,true,natural,surprising,good,wonderful,funny,likely,certain,probable,etc)/名詞詞組（no wonder,an honor , a good thing,a pity,etc)+that從句 e.g.It’s certain that she will do well in the exam/It’s no surprise that our team has won the game.5．It+be+過去分詞（said,reported,thought,expected,decided,announced,etc)+that從句

e.g.It’s said that Mr.Green has arrived in Beijing.Note:that引導(dǎo)主語從句時，在口語和非正式文體中可以省略，但that從句置于開頭時不能省略。e.g.That he suddenly fell ill last week made us surprised.（二）表語從句

表語從句的句型及要點。引導(dǎo)詞疑問詞wh-及whether及that.1、表語從句在復(fù)合句中作表語，位于系動詞之后。疑問詞引導(dǎo)的： e.g.The question was who could go there.Note: 引導(dǎo)表語從句的連接詞that一般不可省去。

e.g.My idea is that we can get more comrades to help in the work.連接詞that一般不能省略，但當(dāng)主句中含動詞do的某種形式時，that可以省略。如： What I want to do is(that)I can go up to him and thank him.我想做的事是走到身邊去感謝他

（三）賓語從句

賓語從句在復(fù)合句中作賓語。引導(dǎo)詞有疑問詞wh-及whether、if(if 和whether 有區(qū)別）及that.引導(dǎo)賓語從句的連詞that一般可省略。e.g.I hope(that)everything is all right.Note:以下情況that不可省略：(不考查）

1.當(dāng)賓語從句的主語是that時。2.2.當(dāng)賓語從句中含有主從復(fù)合句時 Father promised that I studied harder he would take me to Beijing.3.當(dāng)兩個或多個賓語從句由并列連詞連接時，除第一個從句中的that可以省略外，其余從句中的that都不可以省略。

4當(dāng)that偶爾作except和in的賓語時。This book is unsatisfactory in that it lacks a good index.中，that it lacks a good index就是介詞 in 的賓語從句，這當(dāng)中的that就不能省略。

（四）同位語從句。引導(dǎo)詞wh-及whether及that.同位語從句引導(dǎo)詞有疑問詞wh-及whether及that.同位語從句在句中作某一名詞的同位語，一般位于該名詞（如：news, fact, idea, suggestion, promise等）之后，說明該名詞的具體內(nèi)容。e.g.I have no idea when he will be back.The fact that he had not said anything surprised everybody.名詞性從句易混知識歸納

易混點一 ：同位語從句與定語從句的區(qū)別

that引導(dǎo)的從句，是定語從句還是同位語從句，我們我們采用“試加 法”，來判斷。The fact that he had not said anything surprised everybody.This is the fact that you must know clearly.1.when、where、why引導(dǎo)的從句

引導(dǎo)定語從句時，其意義與先行詞有關(guān)，與先行詞的意義基本相同，沒有疑問意義；但引導(dǎo)同位語從句時，其意義完全與疑問詞相同，即when表示什么時候，where表示哪兒，引導(dǎo)兩種從句時，都在從句中做狀語。如： I still remember the day when I first came to Beijing.句中的when相當(dāng)于“on the day”它沒有疑問詞“什么時候”的意義，因此是定語從句。

I have no idea when she will be back.when與idea毫無意義上的關(guān)聯(lián)，其意思是“什么時候”,因而是同位語從句。易混點二：reason后面的名詞性從句

reason做主語時，后面的表語從句表示原因是要用that引導(dǎo)，一般不用because或why，而用it，this或that做主語時，后面的表語從句可用because或why引導(dǎo)。

1.“The reason +連系動詞+that“引導(dǎo)的表語從句。本句型的意思是：理由是：。。。The reason was that he fell ill.2.It（或This、That）+連系動詞+the reason+why引導(dǎo)的定語從句。本句型意為：這就是。。。的原因（理由）That is the reason why he failed in the contest, 3.It（或This、That）+連系動詞+the reason+because引導(dǎo)的表語從句。本句型意為：這是因為。。。；這是由于。。。的緣故。That was because he fell ill.4.It（或This、That）+連系動詞+why引導(dǎo)的表語從句。本句型意為：這就是。。。的原因。

That was why he fell ill.易混點三：what、whatever、who、whoever等引導(dǎo)的名詞性從句 我們可以通過與定語從句的轉(zhuǎn)化知道兩組在意義上的差別。Whatever=anything that（無論什么）Whoever=anyone who（無論誰）

Whenever=any time=no matter when（無論何時）Wherever=any place=no matter where（無論何地）這都是泛指。而what、who、when、where則是特指。如： Who spoke at the meeting is unknown The person that spoke at the meeting is unknown.Whoever breaks the law will be punished.Anyone who breaks the law will be punished.注意：1.whatever、whoever、whenever、wherever等常引導(dǎo)主語從句、賓語或表語從句，也可以引導(dǎo)狀語從句，等于“no matter +疑問詞”。而no matter +疑問詞只能引導(dǎo)讓步狀語從句。Eg：Whatever I said/No matter what I said, he wouldn’t listen to me..2whoever的賓格還是whoever，一般不用whomever。易混點 whether與if（不做考查）

二者都可以作“是否”講，能引導(dǎo)名詞性從句，都不能省略。1.在及物動詞后引導(dǎo)賓語從句時可以互換；

注意：在某些動詞后（如:discuss）只能接whether，不能跟if。如： We discussed whether we should close the shop.2.引導(dǎo)主語從句、表語從句、同位語從句時都用whether，不用if。如：

The question whether he should come himself or send another man hasn’t been decided.Whether he will win is all the same to me.The question is whether you can go there yourself.但如果主語從句是有It用作形式主語，if和whether都可以 It is unknown whetherif she is ill.3賓語從句中，如果whether后緊跟or not，不用換做if；若whether與or not分開使用，則可以換作if。如： I wonder whether or not he has arrived at the destination.I don’t know whetherif I can come or not.4.若賓語從句為否定結(jié)構(gòu)，則多用if，而不用whether。如： I don’t care if he doesn’t show up.（炫耀）

5.在介詞后引導(dǎo)賓語從句或與帶to的動詞不定式結(jié)合而構(gòu)成不定式的復(fù)合結(jié)構(gòu)時，只能用whether，而不用if。如：

I haven’t settled the question of whether I will go back home.She doesn’t know whether to get married now or wait.練習(xí)：名詞性從句
