第一篇：中考英語名詞性從句講解含練習(遲)

名詞性從句 主語從句

主語從句的語序

主語從句要求使用陳述句語序，而非一般疑問句語序。如：

What surprised me most was that the little girl could play the violin so well.How he was successful is still a puzzle.連接詞的選用

（1）that和what的選用

that和what都可引導主語從句。what除起連接作用外，還在名詞性從句中充當某些成分，可作從句的主語、賓語或表語。而that在名詞性從句中不充當任何成分，無詞義，只起連接詞作用。如： What he wants is a book.他想要的是一本書。

That light travels in straight lines is known to all.眾所周知，光線沿直線運行。（2）if和whether的選用

引導主語從句，不能用if，只能用whether。如：

Whether we will hold a party in the open air tomorrow depends on the weather.我們明天是否在戶外開晚會要看天氣而定。（3）其它連接代詞和副詞的選用

根據主語從句的具體意義，正確的選擇who, which, when, where, why, how等連接詞，這些連接詞既有疑問含義，又起連接作用，同時在從句中充當各種成分。如：

When we shall hold our sports meet is not decided.我們何時舉行運動會還沒有決定。Who broke the glass yesterday is not clear.還不清楚昨天誰打破了玻璃。

Which car you will choose to buy makes no difference.你決定買哪一輛車都不會有任何區別。（4）whatever / whoever的功用

whatever, whoever在主語從句中不含疑問意義。它引導主語從句，并在從句中作主語、賓語、表語等。whatever = anything that;whoever = anyone who。要注意和whatever, whoever引導的讓步狀語從句的區別。如： Whoever breaks the law should be punished.（主語從句）（＝Anyone who breaks the law should be punished.）Whoever breaks the law, he should be punished.（讓步狀語從句）（＝No matter who breaks the law, he should be punished.）

it構成的主語從句（1）由連詞that引導的主語從句，在大多數情況下會放到句子的后面，而用代詞it作形式主語。謂語是seem, appear, be certain, be a pity, be a wonder, be one's hope, be likely等詞或短語時。

It is well-known that the earth moves around the sun.眾所周知，地球圍繞太陽轉。

需要注意的是，it作形式主語代替主語從句時，要注意和as引導的定語從句的區別。試比較： It was reported that the US was under the terrorist attack.（主語從句，有that，無逗號）

As was reported, the US was under the terrorist attack.（定語從句，無that，有逗號）上兩句意為“據報道，美國遭到恐怖分子的襲擊”。

用于It is suggested / required / ordered / demanded that...句型中,動詞為表示命令、建議、要求等意義的詞。主語從句應使用虛擬語氣,謂語動詞用“should + 動詞原形”,should可以省略。例如:

It is suggested that you(should)spend more time in studying English.你應該花更多的時間學習英語。（2）常見用it作形式主語的復合句結構

1.It is a fact（a good idea / a pity / a shame / no wonder / good news…）that…如： It's a pity that you missed the film.你沒有看那部電影真是太遺憾了。

2.It is necessary（clear / true / strange/ important /wonderful / possible / likely…）that…

需要注意的是，這類主語從句中，謂語動詞很多為“（should）＋動詞原形”，即要用虛擬語氣。如： It is necessary that you（should）master the computer.你很有必要掌握電腦。It is important that a student learn English well.學生學好英語很重要。It's clear that they badly need help.很明顯，他們急需援助。

It is likely that a hurricane will arrive soon.颶風很可能馬上就要到達了。

3.It is reported（well-known / hoped / thought / expected /said /believed/decided /suggested /ordered…）that…如： It is said that he was killed in the earthquake.據說他在地震中喪生了。

4.It seems（happened / appears / doesn't matter / makes no difference / …）that …如： It seems that they will win the game.看起來他們好像會贏得這場比賽。

It makes no difference whether he will attend the meeting or not.他是否會參加會議都無關緊要。The Foreign Minister said, “________ our hope that the two sides will work towards peace.” A.This is B.There is C.That is D.It is

句式

用形式主語it引導的主語從句相當多，有些已形成固定的語法和譯法。常見的有： It is said that...據說…… It is reported that...據報導……

It is well known that...眾所周知…… It is announced that...據宣布…… It is believed that...人們相信…… It is thought that...人們認為……

It is understood that...自不待言…… It must be pointed out that...必須指出…… It must be admitted that...必須承認……

否定轉移

1)將think, believe, suppose, expect, fancy, imagine等動詞后面賓語從句的否定詞轉移到主句中，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。3)有時將動名詞，介詞短語或整個從句的否定轉變為對謂語動詞的否定。

I don't remember having ever seen such a man.我記得從未見過這樣一個人。(not否定動名詞短語 having…)It's not a place where anyone would expect to see strange characters on the street.在這里，人們不會想到在街上會碰上陌生的人。(anyone 作主語，從句中的謂語動詞不能用否定形式。)4)有時狀語或狀語從句中否定可以轉移到謂語動詞前。

The ant is not gathering this for itself alone.(否定狀語)螞蟻不只是為自己采食。

He was not ready to believe something just because Aristotle said so.(否定because狀語)他并不因亞里斯多德說過如何如何，就輕信此事。

She had not been married many weeks when that man's younger brother saw her and was struck by her beauty.(否定狀語many weeks)她結婚還不到幾個月，這個人的弟弟就看見她了，并對她的美貌著了迷。

1.________ you don't like him is none of my business.A.What B.Who C.That D.Whether

2.After Yang Liwei succeeded in circling the earth, ________ our astronauts desire to do is walk in space.A.where

B.what C.that D.how

3.________ leaves the room last ought to turn off the lights.A.Anyone B.The person C.Whoever D.Who 表語從句

表語從句在復合句中作表語的名詞性從句，放在系動詞之后，一般結構是“主語＋連系動詞＋表語從句”。可以接表 語從句的連系動詞有be, look, remain, seem等。引導表語從句的that常可省略。另外，常用的還有the reason is that… 和It is because 等結構。例如：

1)The question is whether we can make good preparation in such a short time.2)This is why we can't get the support of the people.3)But the fact remains that we are behind the other classes.4)The reason he is late for school is that he missed the early bus.同位語從句

同位語從句就是在復合句中作名詞的同位語的名詞性從句。1.同位語從句的功能

同位語從句對于名詞進一步解釋，說明名詞的具體內容，一般由that引導，例如：

1)The king's decision that the prisoner would be set free surprised all the people.2)The order that all the soldiers should stay still is given by the general.2.同位語在句子中的位置

同位語從句有時可以不緊跟在它所說明的名詞后面，而是被別的詞隔開。例如： He got the news from Mary that the sports meeting was put off.3.同位語從句與定語從句的區別

(1)定語從句中的that既代替先行詞，同時以在從句中作某個成分（主語或賓語），而同位語從句中的that是連詞，只起連接主句與從句的作用，不充當句中任何成分。

(2)定語從句是形容詞性的，其功能是修飾先行詞，對先行詞加以限定，描述定的性質或特征；同位語從句是名詞性的，其功能是對名詞進行補充說明。例如：

1)The news that he told me is that Tom would go abroad next year.（他告訴我的消息是湯姆明年將出國。）（第一個that引導的從句是定語從句，that在從句中作賓語）

2)The news that Tom would go abroad is told by him.（湯姆將出國的消息是他講的。）（同位語從句，that在句中不作任何成分）

第二篇：名詞性從句講解

名詞性從句講解

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。歷屆高考試題名詞性從句考查的焦點主要有以下5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的區別

5.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： What he wants to tell us is not clear.他要跟我們說什么，還不清楚。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。

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 It is a pity(a shame, no wonder, etc.)that?

It is necessary(important, natural, strange, etc.)that ? It is said(reported, believed, known, etc.)that? It does not matter(seems,appears etc)? 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詞與引導主語從句表語從句的關聯詞大致一樣，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不可略，且并列句之間由and連接。He has told me(that)he will go to Shanghai tomorrow.他已經告訴我他明天要去上海。He found(that)he lost himself in the forest and that he had no way to dicide the right directions.他發現自己在樹林里迷路了，而他又無法確定正確的方向。

注意：在demand、order、suggest、insist, desire,等表示要求、命令、建議、等意義的動詞后，賓語從句常用“（should）+ 動詞原形”。

I insist that she(should)do her work alone.我堅持要她自己工作。2.用who，whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等關聯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。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持。3.用whether或if引導的賓語從句實為一般疑問句，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“or not”時；

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。Everything depends on whether we have enough money.一切要看我們是否有足夠的錢。

4.注意賓語從句中的時態呼應，當主句動詞是現在時，從句根據自身的句子情況，而使用 不同時態。

I know(that)he will study English next year.（從句用一般將來時）

當主句動詞是過去時態（could, would除外），從句則要用相應的過去時態，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，自然現象，則從句仍用現在時態。

The teacher told us that Tom had left us for America． Our teacher told us that the earth runs around the sun

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為否定式。即將從句中的否定形式移到主句中。We don’t think you are here.我們認為你不在這。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。引導表語從句的關聯詞與引導主語從句的關聯詞大致一樣，表語從句位于連系動詞后，有時用as if引導。其基本結構為：主語 + 系動詞 + that從句。

The fact is that we have lost the game.事實是我們已經輸了這場比賽。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，當主語是reason時，表語從句要用that引導而不是because。例如： The reason why he was late was that he missed the train by one minute this morning 4.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： 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。同位語從句和定語從句的區別：

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。

試比較下面兩個例句:

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

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

第三篇：名詞性從句講解

名詞性從句與高考試題

名詞性從句的界定與分類：

名詞性從句相當于名詞，可分別作主句中的主語、表語、賓語和同位語。因此，名詞性從句可分為主語從句、表語從句、賓語從句和同位語從句。從屬連詞that, if, whether;

連接代詞who, whoever, whom, whomever, which, whichever, what, whatever, whose;連接副詞where, when, why, how。

其中, 從屬連詞只起連接作用, 在從句中不充當任何句法成分，而連接代詞和連接副詞既起連接作用, 在從句中又充當一定的成分.名詞性從句均不能用逗號和主句分開。

一、主語從句：

定義：一個從句在復合句中作主句的主語，這個從句就叫主語從句。

二、主語從句的表現形式： １.由從屬連詞引導的主語從句：

a.Whether the country should build a nuclear power station is something we must discuss.b.That light travels in straight line is known to all.２.由連接代詞引導的主語從句： a.What we need is more time.b.Whichever book you choose doesn’t matter to me.c.Whoever comes will be welcome.３.由連接副詞引導的主語從句：

a.When the plane is to take off hasn’t been announced ． b.Where he has been is still a puzzle.c.How much water is flowing can be measured easily.三、關于形式主語 it

主語從句放在句首往往顯得頭重腳輕，不太平衡，因此，在大多數情況下都是在主語的位置上用一個形式主語 it，而把主語從句移到句未去。

關于形式主語 it: 以 it 作形式主語，把主語從句后置的常用句型有：（1）It + be + 形容詞 + that/wh-從句

It is quite clear that Tom was fond of music.（2）It + be + 名詞 + that/wh-從句

It is a pity that she has made such a foolish mistake.可應用于此句型的名詞還有fact / shame / honor / question等。（3）It + be + 過去分詞 + that/wh-從句

It’s not yet decided that when the test will be given.（4）It seems, happens 等不及物動詞 + that/wh-從句 It happened that I didn’t take any money with me.但以下情況往往必須用it作形式主語，主語從句一般不能放在句首。a.It doesn’t matter whether he likes or not.b.It’s said that the highway will be open to traffic next year.c.Is it likely that it will snow in the afternoon? 練習：

6． ____ he said at the meeting astonished everybody present．（MET93）A．What B．That C．The fact D．The matter 二, 表語從句：

定義：一個從句在復合句中作主句的表語，這個從句就叫作表語從句。可以接表語從句的連系動詞有 be, look, remain, seem 等。

1.The problem is that millions of people die of illnesses caused by smoking.2.The question remains whether we can win the people.3.That’s just what I want.4.This is where our problem lies.5.The difficulty is how I can help smokers kick their habit.值提注意的是：

1.表語從句的表現形式除了用從屬連詞，連接代詞和連接副詞引導以外，還可以由as, as if ,as though引導.Things were not as they seemed.It looks as if it is going to rain.2、另外還要注意以下常用的兩種結構：

The reason why…is that …(而不用 because。)It(this, that)is because…

The reason why he was dismissed is that he didn’t work hard.It is because the tobacco companies want to remain in business.練習：

1.What the doctors really doubt is____ my mother will recover from the serious disease soon．

A．when B．how C．whether D．why

4.I had neither a raincoat nor an umbrella．____I got wet all through．（98上海）A．It's the reason B．That's why C．There's why D．It's how 三，同位語從句：

定義：在復合句中，用作同位語的從句稱為同位語從句。

同位語從句一般由 that, whether 等連詞引導，常放在 advice, doubt, fact, hope, idea, information, message, news, order, possibility, problem, question, reason, truth, word, suggestion.等名詞的后面，說明該名詞的具體內容。

l.The news that he had landed on the moon spread all over the world.2.I have no idea when he will be back.3.The thought came to him that Mary had probably fallen ill.4.He must answer the question whether he agrees to it or not.同位語從句和定語從句的區別：

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。

試比較下面兩個例句:

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

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

2.______ is no possibility _______.Bob can win the first prize I the match.(上海2001春)A、There;that B、It;what C、There;whether D、It;whether 四，賓語從句

定義：一個從句在復合句中作主句的賓語，這個從句就叫作賓語從句。賓語從句可以作及物動詞的賓詞，介詞的賓語，某些形容詞的賓語以及非謂語動詞的賓語。1．及物動詞后的賓語從句：

She will give whoever needs help a warm support.I wonder why she refused my invitation.2．介詞后的賓語從句：

I always think of how I can improve my spoken English.The teacher is satisfied with what she has said.3．某些形容詞后的賓語從句：

I am sure that you will make greater progress in English through hard work.We are surprised that he has left without saying goodbye to us.關于形式賓語it

We must make it clear that anyone who breaks the law will be punished.I find it necessary that we should ask him for his advice.練習：

學習名詞性從句時要注意以下幾點：

1.在名詞性從句中，疑問句要用陳述句的語序。例如：

Someone is ringing the doorbell．Go and see ____．（2000上海）A．who is he B．who he is C．who is it D．who it is Can you make sure ____the gold ring ？（MET90）

A．where Alice had put B．where had Alice put C．where Alice has put D．where has Alice put

You can't imagine ____ when they received these nice Christmas presents．（94上海）A．how they were excited B．how excited they were C．how excited were they D．they were how excited

2.動詞 doubt 用在疑問句或否定句時，其后賓語從句常用 that 作連接詞；用在肯定句時，連接詞用 whether 或 if 皆可，而不用 that。

Do you doubt that he will win ? I don't doubt that your proposition is wrong.He doubt whether I know it.3.否定轉移問題。在主句為第一人稱主語后跟 think , believe , suppose , expect , guess , imagine 等動詞時，賓語從句的否定形式應轉移到主句中。We don't expect he will come tonight , will he ? 4.主謂一致問題。

What he wanted to see was an end to all the armies of the world． What I bought were three English books． 5.語氣問題

a.在含有 suggest , order , demand , propose , command , request , insist, desire, require, advise 等表示要求、命令、建議、決定等意義的動詞后，that從句常用“（should）+ 動詞原形”的結構

I suggest we(should)set off at once.b.在It is ＋過去分詞＋that的主語從句中 decided，demanded，desired，insisted，ordered，proposed，suggested，recommended，requested，required等。It is desired that we（should）get everything ready this evening． c.在表語從句或同位語從句中。

The suggestion that the mayor(should)present the prizes was accepted by everyone．

d.在It is（was）＋形容詞＋that從句中要用虛擬語氣，即（should ＋）動詞原形，表示建議或不滿、驚奇等情緒。常用于此類的形容詞有 essential，important，natural，necessary，possible，strange，等。It is necessary that a college student ________ at least a foreign language．（上海1993）

A．masters B．should master C．mastered D．will master 6．What引導名詞從句的特殊含義:

What was once regarded as impossible has now become a reality．

(what為“所……的事”，相當于“the thing that．．．；all that．．．；everything that．．．”)After ________ seemed a very long time，I opened my eye and found myself in bed．

A．what B．when C．that D．which

He is not what he was a few years ago． Who is it that has made Fred what he is now？ What is now the North Sahara Desert was once a civilized world． Our income is now double what it was ten years ago

D.What;that 1.選D。what made matters worse 是主語從句(注意其后有謂語動詞was)，相當于 the thing that made matters worse。

2.選A。what 引導的是表語從句，相當于 the thing that it takes to do anything well。3.選C。that 引導的是一個主語從句，句首的it為形式主語。

4.選 C。答句為省略句，其完整形式為 I was trying to prove to the police where I was last

night，在此 where 引導的是一個賓語從句。類似地，下面選 C：

“_______ made her struggle to become an artist so hard?” “______ she was a woman.” A.What, What

B.That, That C.What, That

D.That, What 5.選D。what 引導的是表語從句，what 在此相當于 the things that。

6.選 C。句首的 it 是形式主語，空格處所填詞用于引導主語從句。由于該主語從句中又缺主語，故排除A、B、D。（注意：不能選 A，因為 that 引導名詞性從句時不能充當句子成分）7.選 A。第一空填 what，是因為該主語從句中的動詞 understand 缺賓語；why 和 because 均可引導表語從句，其區別是： why 引導表語從句強調結果，because 引導表語從句強調原因。句中空格后文表明的是結果，故用 why。

8.B。what 在此引導主語從句且在從句作賓語，它相當于 the thing that。

9.B。兩空均填 what，均用于引導賓語從句，因為兩個賓語從句中的動詞 said 和do 均缺賓語，而在各個選項中只有 what 可用作賓語。

10.選 A。what 引導賓語從句。由于動詞 wants 缺賓語，所以填 what。句意是：當你找工作面試回答問題時，請記住這條黃金定律：永遠給予對方確實想要的東西。

11.選 A。I can to save them 為 I can do to save them 之略，此句中的 do 缺賓語，故選 whatever。

12.選 B。that 在此引導主語從句，無詞義，也不充當句子成分。注意不要根據中文意思選 D，因為 because 不用于引導主語從句。13.選 C。兩個空格處均為引導賓語從句的引導詞，而四個選項中兩者可引導賓語從句的只有 C。

14.選 B。比較 That’s why? 與 That’s because?：前者用于強調結果，后者用于強調原因。如下面一題選 D：

I got wet all through._______ I had neither a raincoat nor an umbrella.A.It’s the reason

B.That’s why C.There’s why

D.That’s because

15.選 D。由 is worth praising 這一謂語可知前面是主語從句，排除不能引導從句的 B 項和 C 項；whoever 引導主語從句表示“任何??的人”，在此它相當于 anyone who。16.選 A。how 引導主語從句，that 引導同位語從句。

2.B 通過對句子的分析可知，believe it or not是插入語，在此句中that引導的是the story的同位語從句。

3.D 通過對句子的分析可知，此題需要選一詞來引導表語從句，而從句中的明顯缺少賓語，故只能what用來充當。4.C 介詞on后面賓語從句不完整，同時從句缺少主語，故只能由what來充當。

5.C wonder后面的從句是疑問句應用陳述語序。即：特殊疑問詞+主語+謂語動詞。6.B 此句主句完整，從句也完整，故用that引導構成與the fact的同位語從句。7.A why在它引導的從句中充當原因狀語，從句在主句里充當介詞on的賓語。

8.B what在它引導的從句中充當主語，同時整個從句可看成是idea的同位語從句，來說明idea的具體內容。9.B 本題考查定語從句以及固定短語turn to 的用法，關系代詞因為在后面定語從句中做賓語因此省略掉，turn to sb 求助于某人。

10.B 本題根據意思以及后面與or 的搭配關系可判斷該處是“是否”，whether 引導賓語從句。

11.B 本題考查名詞性從句中的同位語從句，根據下文可知Danny留下的口信的內容，that 引導名詞性從句。

12.C 本題考查雙重疑問句，疑問詞＋do you think/believe/expect＋句子的其他成分（句子用稱述句語序）。13.C 本題考查固定短語 be different from同時也考查名詞性從句中的賓語從句，介詞from后是賓語從句，但從句中be used to 后面少賓語，且根據上文是我們過去習慣的方法，這用what 符合語意。

14.A 本題考查的是名詞性從句中的表語從句，后面表語從句不完整，it was 后面還缺少表語，根據意思是“20年前的 樣子”，后面一個句子是對20年前的補充說明，是一個非限制性定語從句，20年前學校設備條件不好，when 在定語從句中作時間狀語。

15.B 本題考查名詞性從句的同位語，doubt 后的同位語根據意思沒有懷疑故選擇that 引導，that在從句中不充當成分。

強化題

1.C whether引導的從句構成與名詞the question的同位語。(原答案似乎有誤)2.C 主句完整,同時從句也不缺成分。根據句意可看出that引導的從句構成與a warm thought的同位語。3.A that引導同位語從句，具體說明chance（可能性）的內容。4.B 句意：請提醒我他說他將什么時候走。

5.B 因先行詞是natives，故淘汰A和D。又因give sth.to sb.固定短語，所以選B。介詞to可放在關系代詞whom的前面。w.w.w.k.s.5.u.c.o.m 6.B pleased后面缺少賓語從句，he was a man of action句意完整，故用that引導。

7.D No matter what/which只能引導讓步狀語從句，排除A和B。C和D的區別在于一個無范圍，一個有范圍。8.D wonder后面的賓語從句本是what makes him so excited：。但what需要被強調，故用強調句型。9.D 本題考查it 作形式主語, 后面的that 引導真正的主句從句.10.B 本題考查同位語從句, reason 后面有for 引導的短語, 接著后面是that 引導的句子來說明理由的內容.11.C 本題考查名詞性從句的賓語從句,介詞for 后接賓語從句但賓語從句中缺少主語, he thought 是插入語.連詞what 引導賓語從句且在從句中充當主語,which 的意思不符合.12.C 本題考查固定短語 be different from同時也考查名詞性從句中的賓語從句，介詞from后是賓語從句，但從句中it had been 后面少表語，所以what 符合語意。

13.B 本題考查名詞性從句中的介詞賓語從句, 根據下文意思以及在賓語從句中作主語, D 不能引導名詞性從句, who 表達的意思不對.14.C 本題考查名詞性從句介詞賓語, 賓語從句中you think 是插入語, 故句中缺少主語,which 意思不對,故選wh at

15.C 本題考查介詞賓語從句, 根據上下文意思 該處應該是”我們是否能得到Green先生的
