2019-2020年高考英語 易錯點點睛與高考突破 專題09 名詞性從句 【xx高考預(yù)測】 1.名詞性從句中連接詞的正確選用 2.that引導(dǎo)的賓語從句，wh-引導(dǎo)的賓語從句以及某些特殊詞后所跟的賓語從句 3.that和wh-引導(dǎo)的主語從句及形式主語的幾種主要句型 4.獲that、wh-疑問詞引導(dǎo)的表語從句及從屬連詞引導(dǎo)的表語從句、同位語從句 5.名詞性從句中，從句部分的語序要用陳述語序，不能用凝問語序 6.that引導(dǎo)同位語從句與定語從句的區(qū)別 7.Whether和if在名詞性從句中的用法區(qū)別 【難點突破】 一、各類名詞性從句的區(qū)別 1．who/whoever, what/whatever等的用法區(qū)別：一般說來，在名詞性從句中what/who雖然不表示疑問的語氣，但是所陳述的內(nèi)容卻是未知的，含特指意義，而whatever/whoever等含泛指意義，意為“無論什么，無論誰”，并且表達的語氣很強烈。 2．whether/if的用法區(qū)別：whether和if在賓語從句中可以互換，但是作某些介詞的賓語時連接詞一般用whether；whether可與or not/or連用，用來引導(dǎo)主語從句、表語從句、同位語從句等，也可與動詞不定式連用；if不能與動詞不定式連用。 3．“疑問詞＋ever”和“no matter＋疑問詞”的區(qū)別；“疑問詞＋ever”可引導(dǎo)名詞性從句，在從句中充當(dāng)一定的成分；還可引導(dǎo)讓步狀語從句；“no matter＋疑問詞”只能引導(dǎo)讓步狀語從句，不能用于名詞性從句中。 二、要注意名詞性從句和定語從句、狀語從句的不同 三、解決名詞性從句的相關(guān)題目的步驟 1．名詞性從句可以充當(dāng)主語、賓語、表語和同位語，要分清句子結(jié)構(gòu)，然后再確認試題考查的名詞性從句的所屬類型。 2．正確選擇連接詞。一般說來，引導(dǎo)名詞性從句的連接詞包括連接代詞和連接副詞，其中代詞在從句中起名詞的作用，作主語、賓語或表語；而副詞則充當(dāng)狀語，表示時間、方式、原因等。 例1、(xx遼寧卷)The newer went to the library the other day and searched for ________he could find about Mark Twain. A．wherever B．however C．whatever D．whichever 【特別提醒】 whatever ※在名詞性從句中whatever語氣強，一般相當(dāng)于what，可被其代替。 He will do what/whatever he can to help us.兩者均可，whatever最佳。 例3、　(xx福建卷)We promise ________attends the party a chance to have a photo taken with the movie star. A．who B．whom C．whoever D．whomever 答案　C　[whoever在賓語從句中作主語，promise sb sth結(jié)構(gòu)。] 例4、The prize will be given to ________performs best. A．who B．whom C．whoever D．whomever 答案　C　[whoever在賓語從句中作主語，whoever＝anyone who。], 【特別提醒】 whoever/whomever who/whom ※whoever/whomever名詞性從句表示“……的人”；who/whom名詞性從句表示“誰……”一件事。 例5. (xx陜西卷)As many as five courses are provided, and you are free to choose ________suits you best. A．whatever B．whichever C．whenever D．wherever 【特別提醒】 whatever/whichever ※what I dont know what color she likes. which在名詞性從句中作定語[which＋n./pron.(單數(shù))]有范圍 So many books here, I dont know which one I should take. 例7、(xx陜西卷)The howto book can be of help to ________wants to do the job. A．who B．whomever C．no matter who D．whoever 答案　D　[此處考查賓語從句，whoever在從句中作主語。] 【特別提醒】 whever ※who/whom/whoever/whomever除外 鑒別辦法：截枝法 將從句去除，若主句主干結(jié)構(gòu)[即主謂(賓)/主系表]完整，則考查狀語從句(定語從句無whever引導(dǎo)詞，同位語從句whever從未考查)；若主句結(jié)構(gòu)不完整，則考查名詞性從句。 例8、(xx江西卷)Why dont you bring ________to his attention that youre too ill to work on? 【特別提醒】 常見句型 1.＋ 2．sb/sth＋v.＋it形式賓語 adj./n....＋ 例11、(xx重慶卷)Evidence has been found through years of study ________childrens early sleeping problems are likely to continue when then grow up. A．why B．how C．whether D．that 【特別提醒】 同位語從句后移現(xiàn)象 1．同位語從句為了句子結(jié)構(gòu)平衡，從主句謂語之前移至主句謂語之后。 2．定語從句后移現(xiàn)象與之極為類似，只是從句性質(zhì)不同，詳見定語從句熱點13。 例13、Someone is ringing the doorbell.Go and see ________． A．who is he B．who he is C．who is it D．who it is 答案　D　[考查賓語從句語序和it指代人的用法。] 例14、He looks upset but I dont know ________with him. A．what is the matter B．what the matter is C．what the matter was D．what was matter 答案　A　[考查從句語序。what is the matter為主系表結(jié)構(gòu)。] 例15、I wonder ________I met him before! A．where was it B．where was it that C．where it was D．where it was that 答案　D　[考查從句語序。在從句中須用陳述語序。], 【特別提醒】 1．雖然所有從句(省略、倒裝特殊句式除外)都須是陳述語序，但涉及從句語序問題，大多考查名詞性從句，尤其賓語從句。 2．近年來強調(diào)句型和名詞性從句結(jié)合考查語序比較常見。 例16、(xx天津卷)It doesnt matter ________you turn right or left at the crossing—both roads lead to the park. A．whether B．how C．if D．when 例18、(xx安徽卷)The limits of a person’s intelligence, generally speaking, are fixed at birth, but ________he reaches these limits will depend on his environment. A． where B．whether C．that D．why 答案　B　[句意：一個人的智力極限，通常來說，出生時就已經(jīng)定型了。但他是否能夠達到這些極限取決于他所處的環(huán)境。根據(jù)depend on可知，主語從句含有不確定因素，可排除C。where表示地點，why表示原因，用于此處不合適，而使用whether表示“是否”，與題意吻合。] 例19、(xx浙江卷)It is uncertain ________side effect the medicine will bring about, although about two thousand patients have taken it. A．that B．what C．how D．whether 【特別提醒】 whether if 4種名詞性從句 賓語從句(有限制) whether to do if to do whether從句可作介詞賓語 if從句不作介詞賓語 ①I dont know whether or not he will e.√ ②I dont know whether he will e or not.√ ①I dont know if or not he will e. ②I dont know if he will e or not.√ 【易錯點點睛】 易錯點點睛 1 名詞性從句中連接詞的正確選用 1 、Mary wrote an article on __ the team had failed to win the game. A. why B. wtat C. who D. that 【錯誤解答】 B或D 【錯解分析】 許多考生都誤以為what在本題中充當(dāng) failed的賓語，或認為空格后不缺成分，故選B或D。實際上就本題而言，不難看出句意為“瑪麗寫了一篇關(guān)于隊伍為何在比賽中失敗的文章”，所以應(yīng)該選用強調(diào)原因的why。 【正確解答】 A 2 、A puter can only do __ you have instructed it to do. A. how B. after C. what D. when 4. His ability has never been in doubt—the question is he is prepared to work hard. A. whether B. if C. that D. where 【錯誤解答】 B 【錯解分析】 很多同學(xué)對whether和if的用法一知半解，盡管二者都有“是否”的意思，但在主語、表語或同位語從句中只能用whether，不能用if。 【正確解答】 A 5. He can’t answer the question hegot the money. A. what B. that C. how D. where 【錯誤解答】 B 【錯解分析】 許多考生知道這是一個同位語從句，在定性思維中認為同位語從句用出at引導(dǎo)，事實上同位語從句也可用when，where，why等來引導(dǎo)，不一定只用that. 【正確解答】 C 【特別提醒】 1.that引導(dǎo)名詞性從句時，在從句中無意義，不作成分，只起到連接作用，在賓語從句中可省略。 He told me (that) he would leave soon. 2.what與出at在名詞性從句中的區(qū)別。 Right:What he said was true. 這是一個主語從句，what在從句中作動詞said的賓詞，意思是:“……話”或“……事”，此句中不能用that。 That he came late made the teacher angry. 這個句子還是主語從句。從句中意思完整，所以用that來引導(dǎo)，起到一個標(biāo)志作用。 【變式探究】 1 I try to understand __ prevents them from being as happy as one might expect although they are so rich. A. that B. what C. it D. whether 答案: B 解析:what引導(dǎo)賓語從句。 2 Although Mary is happy with her success she wonders __ will happen to her private life. A. that B. this C. it D. what 答案: D 解析:what引導(dǎo)賓語從句。 3 The dealer told me how much he was prepared to pay for my car and __ I could have the money without delay. A. what B. that C.不填 D. whether 答案: B 解析:what只起連結(jié)詞作用，本身無義。 I have found out __ they will ask to lead the vic- tory march on Saturday. A. when B. where C. whom D. what 答案: C 解析:whom引導(dǎo)一個賓語從句，在賓語從句中又作ask的賓語。 5 It was not until dark he found he thought was the correct way to solve the problem. A. that; what B. that; that C. when; that D. when; that 答案: A 解析:這是一個帶有賓語從句的加強調(diào)句型。主句是not…until句型。 易錯點點睛 2 that引導(dǎo)的賓語從句，wh-引導(dǎo)的賓語從句以及某些特殊詞后所跟的賓語從句 1. As soon as he es back, I will tell him when and see him. A. you will e B. will you e C. you e D. do you e 3. The leaders of the battle ordered all of us the work on time. A. if;finished B. that;finish C. whether; finished D. what; finished 【錯誤解答】 A或C 【錯解分析】 許多考生認為A、C答案均講得通，即“任務(wù)是否要以接時完成”，但本題由于受ordered這個詞的限制，應(yīng)該選B。其中finish為should finish的省略形式。 【正確解答】 B 4. Most of the university students are confident __ they can get a good job with higher pay. A. whether B. that C. where D. when 【特別提醒】 1.出at引導(dǎo)的賓語從句出at常用來引導(dǎo)賓語從句，通常that可以省略。 He has told me that he will go to Shanghaitomorrow．他已經(jīng)告訴我他明天要去上海。 注意：在demand，order，suggest，decide等表示要求、命令、建議、決定等意義的動詞后,hat從句 常用“(should)+動詞原形”的結(jié)構(gòu)。 2.wh-引導(dǎo)的賓語從句 I want to know what he has told you．我想知道他告訴了你什么。 3.形容詞后所跟的賓語從句 某些動態(tài)形容詞(afraid，confident，aware，certain，sure，doubtful等)在句中做表語時，后面可跟賓語從句。 例句:I am confident that I can get the job．我有信心我可以得到這份工作。 【變式探究】 1 We can’t figure out __ quite a number of insects, birds, and animals are dying out. A.that B. as C. why D. when 3 Mr Smith suggested that all of the students __ their exercise books. A. handed in B. should hand in C. handing in D. that hand in 答案: B 解析:盡管動詞suggest用了過去式，但suggest后若跟賓語從句，則從句部分應(yīng)用shoulddo結(jié)構(gòu)。 易錯點點睛 3 that和wh-引導(dǎo)的主語從句及形式主語的幾種主要句型 1. After Yany Liwei succeeded in circling the earth, our astronauts desire to do is walk in space. A. where B. what C. that D. how 【錯誤解答】 C或D 【錯解分析】 本題考查主語從句。首先排除C，因為該主語從句缺成分，而that不充當(dāng)任何成分的。where和 how只能充當(dāng)狀語成分，而本句缺少do的賓語，因此應(yīng)選B. 【正確解答】 B 3. It is a shame __ we lost that expensive car. A. that B. when C. as D. if 【錯誤解答】 B或D 【錯解分析】 很多考生不知道It在本句中作形式主語。本句實際上是It is／was a+名詞+that結(jié)構(gòu)。 【正確解答】 A 【特別提醒】 (1)that引導(dǎo)的主語從句 that引導(dǎo)的主語從句既可以放在句首也可以放在句末，在實際應(yīng)用中常常采用it形式主語形式。 That he passed the English test is true.→ It is true that he passed the English test. (2)形式主語的四個主要句型 It + be + 名詞 + that從句 It is a pity that...可惜的是，用于此句型的名詞還有fact／shame／honor／question等。 It + be + 形容詞 + that從句 It is certain that...很肯定，可用于此句型的形容詞還有clear／better／natural／important／neeessary. It + be + 動詞的過去分詞 + that從句 It is said that...據(jù)說，可用于此句型的過去分詞還有believed／known／reported等。 It + 不及物動詞 + that從句 如: It seems that...好像是……似乎…… 可用于此句型的不及物動詞還有happen，appear等。 【變式探究】 1 __ there is life on another planet is almost impossible.
