高考英語【名詞性從句】

專題十 名詞性從句第一節(jié) 基本知識與基本概念【什么是名詞性從句？】根據(jù)從句在句子中的功能分根據(jù)從句的性質(zhì)分定語從句形容詞性從句主語從句名詞性從句賓語從句表語從句同位語從句狀語從句副詞性從句【主語從句】顧名思義，主語從句在句子中作主語。有時本身出現(xiàn)在主語的位置上，也有時出于句子結(jié)構(gòu)的考慮退到句子的尾部，前面用形式主語it代替。從句作主語時，謂語動詞一般為單數(shù)形式。如: What I saw was beyond any verbal description. That his hair was turning grey worried him a bit. Why the company denied the contract is still unknown. When and where the government will build a city square is under discussion. It is pretty annoying that a small part of the machine is missing. It remains to be seen whether the new novel will be well received. 【賓語從句】 在句子中作賓語的從句就是賓語從句。由于這是同學(xué)們接觸比較早的一種從句，應(yīng)該問題不大。所以在近年的高考題中，以賓語從句的知識作為考點的題目較少。但是，賓語從句也有自己的特殊情況，如介詞的賓語，形容詞的賓語，賓語從句提前和并列的賓語從句等現(xiàn)象。如： We assumed that there would be more than 100 guests. He told the police in detail what he saw and heard. Nobody is sure what humans will look like in a million years. That will depend on whether they can get the chance. Whether I will have the time I am not sure at the moment. The conductor complained that we were not gifted in singing and that he would never come again. 【表語從句】 表語從句的最重要臉譜就是它們應(yīng)該出現(xiàn)在系動詞的后面。如： The only question left is how often the workers are paid. His idea for the coming weekend is that we go skating. 【同位語從句】 從臉譜上看，同位語從句最為麻煩。因為它們也是出現(xiàn)在一個名詞的后面，起著解釋說明的作用。有點像定語從句。這個點是許多學(xué)生容易混淆的地方。但是，只有我們能把握住關(guān)鍵，即：定語從句的先行詞在從句中必須作一個成分，并且這個成分應(yīng)該是個空白，也就是說，定語從句必須缺少成分。這一點恰恰是同位語從句所不能做到的。同位語從句前面的名詞在從句中是沒有位置的。況且，也不是所有的名詞后面都會跟同位語從句，只有那些“有內(nèi)容的名詞”才需要解釋。如fact, news, idea, truth, hope, problem, information, belief, thought, doubt等。如： That fact that the policeman didnt fire at the man at all was ignored. Do you have any idea what is going on in the classroom. The possibility that we can work at home makes everybody excited. 【連接代詞、連接副詞和連接詞】 通過以上介紹，我們可以看出，四種名詞性從句都需要有一個連接性詞在從句的開頭。這個詞是什么性質(zhì)，要看它在從句中作作的成分，如果作的是主語、賓語、表語的話，這個詞就是連接代詞；如果作的是各種狀語，就叫連接副詞；如果不作任何成分，就叫連接詞。如下表： 連接詞 that, if, whether引導(dǎo)名詞性從句的連接詞 連接代詞 who, whom, what, whose, which, whichever, whatever, whoever 連接副詞 when, where, how, why第二節(jié) 考點分類解析【考點一：語序問題】名詞性從句的語序問題一直斷斷續(xù)續(xù)地在各地高考題目中出現(xiàn)，由此可見其重要性。其實說來非常簡單易記：永遠陳述語氣。即名詞性從句中不會出現(xiàn)助動詞提前的現(xiàn)象。如：Who he is doesnt matter much.When and where we shall have the sports meet is a question.I dont know what his name is.I dont know what is wrong with him. = I dont know what is the matter with him.You cant imagine how excited I was at that time.Can you tell me what size shoes you wear? No one can be sure _ in a million years. A. what will man look likeB. what man will look likeC. man will look like whatD. what look will man like答案：B。這個題就是典型的考查賓語從句的語序問題。根據(jù)以上所述，應(yīng)該是陳述語序。所以A、C兩個選項就不可能了。而D選項明顯不符合我們的語言習(xí)慣?！究键c二：that和what的區(qū)別問題】能引導(dǎo)名詞性從句的關(guān)系代詞有who, whom, what, whose, which, whichever, whatever, whoever八個。為何單獨講what的用法呢？重要！在考試中出現(xiàn)的頻率高！在本書第一章定語從句中，我們提到過，what是不能引導(dǎo)定語從句的。定語從句中如果缺少的成分是主語、賓語、表語，我們選擇的是關(guān)系代詞that或其他?，F(xiàn)在山頭換了，到了名詞性從句的知識范圍了。What在名詞性從句中就很有用武之地了。還是分析成分，what 在從句中作的主語、賓語、表語。而that只是一個“連接詞”，既不作什么成分，也沒有什么意義。如: What you did doesnt agree with what you promised. What he couldnt understand was why his teacher was never satisfied with him. The matter of salary is what I care most if I decide to change my profession. What we cant get always seems better than what we have already got. I think that your composition is no better than his. That you dont love her is not my business. What we have seen is different from _. A. we heardB. we have heardC. what we heardD. what we have heardI couldnt agree with _ at the meeting. A. that you saidB. which you saidC. all what you saidD. what you said【考點三：that和whether的區(qū)別問題】有時候，它們兩個比較難以區(qū)別，因為，它們都是連接詞，都在從句中不作成分。但是，它們之間最大的區(qū)別在于“意義”。即that在從句中既不作成分，也沒有自己的意義；而whether就不同了。它雖然不在從句中作什么成分，但是它又意義，即“是否”。這就能夠左右從句的意思，使從句所表達的意思變成一個還沒有確定的因素。如：I dont know whether he can join us or not. Im sure that he can join us. It is none of your business whether I love her. It is none of your business that I dont love her. 綜上所述，區(qū)分that還是whether，重要一點就是看主句需要從句表達一個什么意思，是確定的，還是不確定的；是事實還是疑問。前者選that，后者選whether。如：I have no doubt _ Mr. Johnson will make it here on time. A. that B. whether C. why D. when 答案：。這個題之所以選擇that，就是因為前面的I have no doubt（毫無疑問），這樣的主句已經(jīng)不再需要從句表達什么“是否”了。No one can be sure _ the board will accept our conditions. A. that B. whether C. why D. what 答案：。這個題中的No one can be sure（沒有人能肯定）就要求從句表達一個“董事會能否接受我們的條件”的意思，而不能是一個既定的事實?！究键c四：if和whether的區(qū)別問題】二者在引導(dǎo)賓語從句時都有“是否”之意。但并不是永遠可以互換。一般認(rèn)為，二者可以互換的環(huán)境也只有在賓語從句中。如：He didnt give us explicit reply whether/if he will attend our wedding ceremony. 而在介詞的賓語從句中，在主語從句中，在表語從句中，在同位語從句中，在和不定式搭配的結(jié)構(gòu)中等等，習(xí)慣上只能用whether。如：1. _ well go camping tomorrow depends on the weather. A. IfB. WhetherC. ThatD. Where2. The question of _ they are old or young is not important. A. whichB. whetherC. howD. if3. The question is _ the film is worth seeing. A. ifB. whatC. whetherD. how 4. He doesnt know _ to stay or not. A. ifB. whenC. whetherD. how 5. The news _ our team has won the match is unknown. A. whichB. ifC. whetherD. then值得注意的是：有些資料依然強調(diào)if不能與or not搭配的問題。過去有過這樣的規(guī)定，只是在現(xiàn)代英語中，已經(jīng)不再強調(diào)了而已?，F(xiàn)在認(rèn)為if or not也可以接受?！究键c五：wh-詞和wh-ever的區(qū)別問題】一般認(rèn)為，wh-詞在引導(dǎo)從句時，依然保留了很大部分的疑問詞的本色，所以，它們引導(dǎo)的從句在意思上應(yīng)該表達的是一個“問題”，如：“誰？什么？何時？何地？為何？怎么？”等。而wh-ever已經(jīng)沒有這層色彩，不再關(guān)心這樣的“問題”，而是充滿了讓步的意味，多有“無論”之意。如：The police wanted to know who will benefit most from the old mans death. 警方想知道誰將從老人的去世中受益最多。Whoever will benefit from the old mans death will be questioned by the police. 能從老人的去世之中受益的所有人都將受到警方的盤問。Who will be sent to help the people in the flooded areas hasnt been announced. 誰將被派往洪災(zāi)區(qū)去救援還沒有宣布。Whoever will be sent to work in the flooded areas will spare no effort to help the people in need. 不管是誰被派往災(zāi)區(qū)救援都會全力以赴地幫助災(zāi)民?！究键c六：no matter wh-和wh-ever的區(qū)別問題】二者都有“無論”之意。在引導(dǎo)讓步狀語從句時確實可以互換，沒有什么區(qū)別。但是，no matter wh-只能引導(dǎo)狀語從句，不能引導(dǎo)名詞性從句。Wh-ever則二者兼收，來去自由。由此包含與被包含的關(guān)系決定，二者同時出現(xiàn)而必選其一時，答案肯定是wh-ever。如：Whoever breaks the rules will be punished. (主語從句)Whoever/ No matter who breaks the rules, he/she will be punished. (狀語從句)Dont believe whatever he tells you. (賓語從句)Dont believe him, whatever/ no matter what he tells you. (狀語從句)【考點七：名詞性從句中的虛擬語氣問題】先看賓語從句的虛擬語氣。一般說來，如果從句作的是表示說話人某種觀點、態(tài)度或要求等語氣的動詞的賓語時，從句中要求用should動詞原形的虛擬語氣（should經(jīng)?？梢允÷裕?。這些動詞常見的有：desire, demand, require, request, order, propose, command, advise, suggest等。如：例：He insisted that she （should）spend more time studying. He demanded that we （should）be on time.The boss required that all waiters (should) keep standing all day long. The publishing house suggested that I (should) type my book out. 有兩個特例是高中老師不愿意錯過的。那就是suggest和insist。它們倆后面的賓語從句是否用虛擬語氣還要看具體語境來定。如：The doctor suggested that I had a cold。(這個suggest的意思是“解釋，說明”。后面不用虛擬語氣) The big smiles on her face suggested that she had passed the test. (這個suggest的意思是“表明”。后面不用虛擬語氣)The doctor suggested that I (should) stay in bed for a few day. (這個suggest的意思是“建議”。后面用虛擬語氣) The young man insisted that he was well enough to serve in the army. (這個insist堅持的是一個事實不是一種觀點。后面不用虛擬語氣)That young man insisted that he should be sent to the front. (這個insist堅持的是一種觀點，即“他應(yīng)該被派往前線”。后面用虛擬語氣)以上是賓語從句中的虛擬語氣現(xiàn)象。如果是其他三種名詞性從句，只要和上述動詞有關(guān)，也享受同樣的待遇。如： The headquarters suggestion is that we (should) wait for another few days. (表語從句) His order that all the soldiers (should) swim across the river was refused. (同位語從句) It is strongly recommended that you (should) take a taxi. (主語從句)另外，在下面這幾個特殊的句型中，后面的主語從句也用虛擬語氣。a. It is important/ necessary/ natural/ a wonder/ essential（必要的）/suggested thatshould do 如：It is important that you （should）be on time. It is necessary that you (should) exercise regularly. b. I wish that did. 如：I wish I were a bird. I wish one day I could live on the moon. c. Id rather that did 如：Id rather you did it yourself. Id rather I hadnt lent you that bicycle yesterday. 【考點八：賓語從句的反意疑問句的問題】眾所周知，反意疑問句是由句子的謂語和主語的代詞形式共同構(gòu)成。如：He is ignorant, isnt he? He isnt strong, is he? 但是，如果前面的句子中含有賓語從句，怎么辦？答案是一定針對主句的主語、謂語。如：You know he is ignorant, dont you? I told you he isnt strong, didnt I? 有一種例外，當(dāng)主句的主語是I,且謂語動詞是表示觀點的動詞如think, believe, suppose, expect, am afraid等時，就只能針對從句反問了。因為沒有人會對自己的觀點嗎上進行反詰。如：I think he is ignorant, isnt he? I believe he isnt strong, is he? 【考點九：it在名詞性從句中的作用問題】 代詞it的用法有很多。但近幾年的高考關(guān)注的卻比較集中，即it作為普通回指代詞的用法和在名詞性從句中作形式賓語和形式主語的用法。如： 作形式主語：It worried me a bit that he didnt phone.It occurred to me that she might have forgotten the date.It doesnt matter when you arrive- just come when you can.It wasnt clear to anyone why he didnt come.It was surprising how many unhappy marriages there are. 作形式賓語：I made it clear that I was determined to carry out the plan.I find it necessary that we should spend more time practising spoken English.I think it important that we should keep calm.Dont take it for granted that your parents should do everything for you.He doesnt want it to be known that hes going away.You may depend upon it that all the goods will be delivered in time.【考點十：主語從句和強調(diào)句型的混淆問題】 從表面上看，it作形式主語的主語從句有時候和強調(diào)句型有些相似。如： It is impossible that we can persuade him to join us. (主語從句) It is with Toms help that we were able to persuade him to join us. (強調(diào)句型) 其實，強調(diào)句型其實很簡單，即在It is/was 與that之間放上我們想要強調(diào)的某個句子成分。大部分考題都是考查that的選擇問題。即考查考生判斷某句是否是強調(diào)句型的問題。這個看似容易的問題在出題人的多種變化之下有時也會變得很令人頭疼。下面是幾種常見的出題形式： 1基本式：It was on the top of the mountain that we met the foreign tourist. 2. 一般疑問句式：Was it on the top of the mountain that you met the foreign tourist? 3. 特殊疑問句式：Where was it that you met the foreign tourist? 4復(fù)合句式：Can you tell me where it was that you met the foreign tourist? 5套定語從句式：It was in the house which was built by his father that he was born. 6. 套定語從句加省略式：- Where did you meet the foreign tourist? - It was in the hotel where we lived (that we met the foreign tourist). 判斷一個句子是否是強調(diào)句型是個關(guān)鍵。這里重要思路是當(dāng)去掉強調(diào)句型、各個成分各歸其位以后，該句子是否還成立。下面幾個例子就不是強調(diào)句型：It was not yet seven oclock when he came back last night. 因為，*He came back last night not yet seven oclock.就不是個正確的句子。- I heard that Tom was once almost drowned. When was that? - It was in 2000 when he was swimming in a pool. 同理，*He was swimming in a pool in 2000. 從邏輯上看也不成立。因為，我們不可能一整年都在游泳。第三節(jié) 鞏固練習(xí)（一）、【夯實基礎(chǔ)】 1.
