1、湖北省麻城市集美學(xué)校七年級英語下冊 名詞性從句素材 人教新目標版在句子中起名詞作用的句子叫名詞性從句 (noun clauses）。 名詞性從句的功能相當(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，名詞性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。引導(dǎo)名詞性從句的連接詞可分為三類：連詞（5個）：that （賓語從句或表語從句中"that"有時可以省略）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

2、接代詞（9個）：what, whatever, who, whoever, whom, whomever, whose, which, whichever連接副詞（7個）：when, where, how, why, whenever, wherever, however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.3. 在從句中做成分的連詞.whether與if 均為"是否"的意思

3、。 但在下列情況下，只可用whether：1. whether引導(dǎo)主語從句并在句首。eg:whether he can come to the party on time depends on the traffic. 2. 引導(dǎo)表語從句。 eg:the question is whether we can get in touch with her.3. whether從句作介詞賓語。eg:i am thinking about whether i should quit my present job.4.if與whether都可以與or not 連用，但后面緊跟or not 時只能用whe

4、ther。we didn't know whether or not she was ready.（此時只能用whether）i wonder whether/if the news is true or not.（此時則二者都可以用）5. 引導(dǎo)主語從句。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.6.引導(dǎo)同位語從句編輯本段分類主語從句作

5、句子主語的從句叫主語從句。主語從句通常由下列詞引導(dǎo)： 1）從屬連詞that，whether,if等； 2）連接代詞what，who，which，whatever，whoever，whom 等； 3) 連接副詞how，when，where，why 等。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。注：whom、who指人，what指物，whatever，whoever表示泛指意義。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

6、 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。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it's a great pity（tha

7、t）they didn't get married.他們沒能結(jié)婚，真是令人惋惜。it 's a good thing（that）you were insured.你保了險，這可是件好事。（2）it be + 形容詞 + that從句it's splendid that you passed your exam.你通過考試了，真棒。it's strange that there are no lights on.真奇怪，沒有一盞燈是開著的。（3）it be + 動詞的過去分詞+ 主語從句i am delighted that you passed your exa

8、m.你通過考試了，我很高興。i'm afraid that i can't come till next week.恐怕我下星期才能來。（4）it + 不及物動詞 + that 從句1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 suggested (requested, proposed, desired, etc.) that眾所周知的幾種表達方式（1）it is kn

9、own to us that. （2）as is known to us.（3）what is known to us is that.it引導(dǎo)的強調(diào)據(jù)結(jié)構(gòu)：it is/was+被強調(diào)部分+that/who+句子其它部分。eg:my father did the experiment in the lab yesterday everning.強調(diào)主語：it was my father who did the experiment in the lab yesterday everning.強調(diào)賓語：it was the experiment my father did in the lab

10、yesterday everning.強調(diào)時間：it was yesterday everning that my father did the experiment in the lab.(注意不用when)強調(diào)地點：it was in the lab that my father did the experiment yesterday everning.賓語從句名詞從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

11、任何成分，在口語或非正式的文體中常被省去，但如果從句是并列句時,第二個分句前的that不可省。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, doubt等表示要求、

12、命令、建議、決定等意義的動詞后，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。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。i want to know

14、ssary that we take plenty of hot water every day.我認為每天多喝開水是有必要的。i feel it a pity that i haven't been to the get-together.我沒去聚餐，感覺非常遺憾。.有些動詞帶賓語從句時需要在賓語與從句前加it，這類動詞主要是：hate,take,owe,have,see toi hate it when they with their mouths full of food.我討厭他們滿嘴食物時說話。we take it that you will agree with us.我們

15、認為你會同意我們的。he will have it that our plan is really pratical.他認為我們的計劃確實可行。4.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：whether引導(dǎo)主語從句在句首時；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。whether he can come to the party on ti

16、me depends on the traffic.他能否準時參加派對得看交通情況。賓語從句放在句首表示強調(diào)時，只能用whether；whether this is true or not, i really don't know.這是會否真實，我也不知道。引導(dǎo)表語從句，只能用whether；the questin is whether we can get in touch with her.問題是我們是否能聯(lián)系上她。引導(dǎo)介詞賓語時,只能用whether；his father is worried about whether he lose his work.他的父親擔(dān)心他是否會失去

18、此時則二者都可以用）后接動詞不定式時，用whether；can you tell me whether to go or to stay? 你能否告訴我是去還是留？i can't decide whether to stay.我不能決定是否留下。用if會引起歧義時，只用whether；could you tell me if you know the answer ?這句話有兩種意思：“你能告訴我是否知道答案嗎？”或“如果你知道答案，請告訴我，好嗎？”。如用whether可避免歧義.whether可引導(dǎo)同位語從句，if不能引導(dǎo)同位語從句。the question whether we

19、should call in a specialist was answered by the family doctor.我們是否請專家由家庭醫(yī)生來定。5. 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)。i know (that) he studies english every day. （從句用一般現(xiàn)在時）i know (that) 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）i know (that

20、) 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)。the teacher told us that tom had left us for americaall of us know that the moon moves round the earth. 6. 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

21、中的動詞變?yōu)榉穸ㄊ?。即將從句中的否定形式移到主句中。we dont think you are here. 我們認為你不在這。i dont believe he will do so. 我相信他不會這樣做。表語從句在復(fù)合句中，位于系動詞之后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+ 聯(lián)系動詞+ that從句1.that 引導(dǎo)表語從句，無詞義，只起連接作用，不可省。2.聯(lián)系動詞可為be,look,seem,sound,appear等。3.主語可為名詞fact,truth,cause,questio

22、n,explanation,trouble,assumption,belief等，代詞this,that,these,it等。the fact is that we have lost the game. 事實是我們已經(jīng)輸了這場比賽。thats 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 didnt 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。raw mat

23、erial is what we are badly in need of.原材料是我們所急需的。china is not what it used to be.中國已不是過去的中國了?！咀⒁狻?.當(dāng)主語是reason時，表語從句要用that引導(dǎo)而不是because。the reason why he was late was that he missed the train by one minute this morning. 2.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。3.that is why 譯為“這就是的原因/因此”。其中why引導(dǎo)的名詞性從句在句

24、中做表語，該句型通常用于針對前面已經(jīng)說過的原因進行總結(jié)。that is why you see this woman before you know.這就是現(xiàn)在這位女士出現(xiàn)在你面前的原因。that is why i came.這就是我來的原因。區(qū)別：that is why 與that is the reason why 同義，只不過從語法結(jié)構(gòu)上講，前者中的why引導(dǎo)表語從句，后者中的why引導(dǎo)定語從句。that is (the reason ) why i cannot agree.這就是我不能同意的理由。that is because 句型中從屬連詞because引導(dǎo)的名詞性從句在此做表語，

25、意為“這就是為什么/因為”。that is because 指原因或理由。that is why 指由于各種原因所造成的后果。he didn not see the film last night. that is because he had to help his little sister with her homework.昨晚他沒有去看電影，那是因為他得幫主他的妹妹做作業(yè)。（第一句話說明結(jié)果，第二句話說明原因）he had seen the film before. that is why he did not see it last night.他以前曾看過那部電影，因此他昨晚沒有

26、去看。（第一句話說明原因，第二句話說明結(jié)果）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 h

27、ome. 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。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 lif

28、e in ancient greece？（that引導(dǎo)定語從句，作賓語，可以省略）名詞性that-從句（1）由從屬連詞that引導(dǎo)的從句叫做名詞性that-從句。that只起連接主句和從句的作用，在從句中不擔(dān)任任何成分，本身也沒有詞義。名詞性that-從句在句中能充當(dāng)主 語、賓語、表語、同位語和形容詞賓語，例如：主語：that she is still alive is her luck.她還活著全靠運氣。賓語：john said that he was leaving for london on wednesday.約翰說他星期三要到倫敦去。表語：the fact is that he ha

29、s not been seen recently.事實是近來誰也沒有見過他。同位語：the fact that he has not been seen recently disturbs everyone in his office. 近來誰也沒有見過他，這一事實令辦公室所有的人不安。形容詞賓語：i am glad that you are satisfied with your job.你對工作滿意我感到很高興。2）that-從句作主語通常用it作先行詞，而將that-從句置于句末，例如：it is quite clear that the whole project is doomed

30、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。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眾所周知it has been decided

31、 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-從句it appears that似乎it happens that碰巧it occurred to me that我突然想起名詞性wh-從句1）由wh-詞引導(dǎo)的名詞從句叫做名詞性wh-從句。wh-詞包括who, whom,. whose, whoever, what, whatever, which, whichever等連接代詞和where

32、, when, how, why等連接副詞。wh-從句的語法功能除了和that-從句一樣外，還可充當(dāng)介詞賓語、賓語補語和間接賓語等，例如：主語： how the book will sell depends on its author.書銷售如何取決于作者本人。直接賓語：in one's own home one can do what one likes.在自己家里可以隨心所欲。間接賓語：the club will give whoever wins a prize.俱樂部將給得勝者設(shè)獎。表語： my question is who will take over president

34、wh-從句置于句末，例如：it is not yet decided who will do that job.還沒決定誰做這項工作。it remains unknown when they are going to get married.他們何時結(jié)婚依然不明。if, whether引導(dǎo)的名詞從句1）yes-no型疑問從句從屬連詞if, whether引導(dǎo)的名詞從句是由一般疑問句或選擇疑問轉(zhuǎn)化而來的，因此也分別被稱為yes-no型疑問句從句和選擇型疑問從句，其功能和wh-從句的功能相同， 例如：主語：whether the plan is feasible remains to be pro

35、ved. 這一計劃是否可行還有待證實。賓語：let us know whether / if you can finish the article before friday.請讓我們知道你是否能在星期五以前把文章寫完。表語：the point is whether we should lend him the money.問題在于我們是否應(yīng)該借錢給他。同位語：they are investigating the question whether the man is trustworthy.他們調(diào)查他是否值得信賴。形容詞賓語： she's doubtful whether we sh

37、你是否喜歡該計劃。if和whether的區(qū)別： 1、 在動詞不定式之前只能用whether 。如： 例8 i cant decide whether to stay. 我不能決定是否留下。 2、 在whether or not 的固定搭配中。如： 例9 i want to know whether its good news or not . 我想知道是否是好消息。 3 、在介詞后，只能用whether。如： 例10 his father is worried about whether he lose his work . 他的父親擔(dān)心是否會失去工作。 4、賓語從句放在句首表示強調(diào)時，只能用

38、whether 。如： whether this is true or not, i really dont know. 這是否真的，我真的不知道。（例11 whether they can finish the work on time is still a problem . 他們是否能準時完成這項工作還是個問題。此例為主語從句，有誤，感謝指出） 5、用if會引起歧義時，只用whether。如： 例12 could you tell me if you know the answer ? 這句話有兩種意思：“你能告訴我是否知道答案嗎？”或“如果你知道答案，請告訴我，好嗎？”。如用wheth

39、er可避免歧義。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

40、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(zhuǎn)變?yōu)閷χ^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 ch

41、aracters 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(zhuǎn)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

42、weeks when that man's younger brother saw her and was struck by her beauty.(否定狀語many weeks)她結(jié)婚還不到幾個星期，這個人的弟弟就看見她了，并對她的美貌著了迷。編輯本段高考相關(guān)熱點1. _ is a fact that english is being accepted as an international language. (nmet 1995)a. there b. this c. that d. it答案d。當(dāng)名詞從句在句中作主語時，為避免句子頭重腳輕，常用it作形式主語置于句首，而將真正

43、的主語從句放在句尾。此時it只起先行引導(dǎo)作用，本身無實義。此句也可以改寫為：that english is being accepted as an international language is a fact.2a computer can only do _ you have instructed it to do（nmet2001） ahow bafter cwhat dwhen 答案c。從句子結(jié)構(gòu)可知，句子的空白處應(yīng)該填引導(dǎo)賓語從句的連詞，做主句謂語動詞do的賓語，同時該連接詞還是從句中的do的賓語，因此，此處的連接詞應(yīng)該用what。3. he asked _ for a viol

44、in（met1992） a. did i pay how much b. i paid how much c. how much did i pay d. how much i paid 答案：d。賓語從句相當(dāng)于特殊疑問句，句子語序要用陳述語序。4. what the doctors really doubt is _ my mother will recover from the serious disease soon（上海2001年春季招生） a. when b. how c. whether d. why 答案c。這是一個表語從句。根據(jù) doubt一詞可知，所懷疑的應(yīng)是是否能治好病，所

45、以要填whether。這句話的意思是“醫(yī)生真的懷疑我媽媽是否能很快從重病中恢復(fù)過來?！?5it is generally considered unwise to give a child _he or she wants. (nmet1997)a. however b. whatever c. whichever d. whenever答案b。根據(jù)句意“一般認為孩子要什么就給什么是不好的?！笨梢钥闯龊竺娴膹木鋺?yīng)是一個賓語從句，而從句中wants缺少賓語，a. however 和d. whenever是不能作賓語的；排除a和d，whichever表示“無論哪一個，無論哪些”，應(yīng)表示一定范圍內(nèi)的

46、人或物，此處沒有涉及事物的范圍，所以應(yīng)選 bwhatever，表示“無論什么”。6. _leaves the room last ought to turn off the lights. (met1988)a. anyone b. the person c. whoever d. who答案c。本題句子的意思是：無論誰最后離開房間一定要把燈關(guān)掉。本題考查連接代詞whoever引導(dǎo)的名詞性從句，連接代詞whoever可以引導(dǎo)名詞性從句，并在從句中作主語，相當(dāng)于any person who或the person who, 意為“一切的人”。而anyone和the person均非連詞，不能引導(dǎo)從

47、句，況who leaves the room last意為“某個最后離開房間的人”，與題意不符，如果要選a. anyone或b. the person，都必須在它們后面再加上引導(dǎo)定語從句的關(guān)系代詞who。如果要選d. who就體現(xiàn)不出“無論誰”的含義了。7. sarah hopes to become a friend of _shares her interests. (shanghai1995)a. anyone b. whomever c. whoever d. no matter who答案為c。本題句子的意思是：sarah希望跟自己有共同愛好的人交朋友。疑問詞+ever引導(dǎo)的名詞性從

48、句與no matter+疑問詞引導(dǎo)的從句的區(qū)別是：前者既可以引導(dǎo)名詞性從句也可以引導(dǎo)讓步狀語從句；后者只能引導(dǎo)讓步狀語從句。首先排除a和d，從句中需要的是主語，所以whomever也不行。8. - i drove to zhuhai for the air show last week. - is that _ you had a few days off ? ( nmet1999)a. why b. what c. when d. where 答案a。根據(jù)語境，甲說上周驅(qū)車去珠海觀看航模展覽。乙據(jù)此來詢問甲這是否是請幾天假的原因，故答案是a。答案b,c, d均與該題語境不符。根據(jù)上句提供的語

49、境，下句應(yīng)該問“那就是你為什么離開幾天的原因嗎？”9. i still remember _ this used to be a quiet village. ( nmet1993)a. when b. how c. where d. what 答案a。根據(jù)從句中缺少的句子成分是狀語，排除dwhat，而答案c, d均與題意不符，所以應(yīng)選awhen。used to be表示一種過去存在的狀態(tài)，本句的意思是“我仍然記得這里在什么時候是個寧靜的地方。”10i read about it in some book or other，does it matter _ it was ?（2001春季招生）

50、 awhere bwhat chow dwhich 答案d。這是一個主語從句。主語從句中缺少表語。從上句的意思分析，應(yīng)是哪本書，所以要填which，這句話的意思是“我在某本書中讀到過有關(guān)這方面的內(nèi)容，是哪一本書重要嗎？”。 11. information has been put forward _ more middle school graduates will be admitted into universities. a. while b. that c. when d. as (2001年上海)答案b。該題考查that引導(dǎo)的同位語從句。同位語從句通常由that引導(dǎo)，接在fact,

51、news, promise, possibility, information, doubt, message名詞后，用來解釋或說明名詞的內(nèi)容。12. i think it is going to be a big problem.yes, it could be.i wonder _ we can do about it.
