上海牛津英語(yǔ)高二下學(xué)期名詞性從句專題講解及訓(xùn)練(有答案)

1、、名詞性從句 主語(yǔ)從句、表語(yǔ)從句、賓語(yǔ)從句、同位語(yǔ)從句，在整個(gè)句子中所起的作用，相當(dāng)于一個(gè)名詞。因此，這四種從句通稱為名詞性從句。引導(dǎo)名詞性從句的連接詞 可分為三類：連接詞：that, whether, if （不充當(dāng)從句的任何成分）連接代詞：what （特指某事物，作主、賓、表語(yǔ)），whateve（泛指任何事物）,who （特指某人，作主、賓、表語(yǔ)）,whoever（泛指任何人），whom （特指某人，作 賓語(yǔ)），whose （表所屬關(guān)系，作定語(yǔ)），which （表選擇關(guān)系，作主、賓、表、定 語(yǔ)）.連接畐詞： whe n, where, how, why（一）.主語(yǔ)從句主語(yǔ) 謂 表語(yǔ)概念：作

2、句子主語(yǔ)的從句叫主語(yǔ)從句，例：What we need is more time1）連接詞：主語(yǔ)從句通常由從屬連詞 that，whether，if，because 不充當(dāng)成分,that 沒(méi)有意義： That she was able to come made us very happyWhether one can succeed depe nds on how hard he worksBecause he is over 60 does nt mea n he must retirgbecause 弓丨導(dǎo)的主語(yǔ)從句只 能放句首，不能用 it 做形式主語(yǔ)）2）連接代詞 what，who，wh

3、ich，whatever，whoever，whose，whom，whomever， whichever，whoever 在主語(yǔ)從句中做成分（主，賓，表，定）What he wants to tell us is not clear.Which team will win the match is still unknownWhoever/whomever you in vite will be welcome3）以及連接副詞 how，when，where，why 等詞引導(dǎo)，在句中做狀語(yǔ)。Where the En glish eve ning will be held has not yet b

4、ee n announ ced.Why he did it rema ins a puzzle forever4)it 的形式主語(yǔ)用法：有時(shí)為避免句子頭重腳輕，常用形式主語(yǔ)it 代替主語(yǔ)從句作形式主語(yǔ)放于句首，而把主語(yǔ)從句置于句末。主語(yǔ)從句后的謂語(yǔ)動(dòng)詞一般用 單數(shù)形式。常用句型如下：(1) It + be + 名詞 + 主語(yǔ)從句(2) It + be + 形容詞 + 主語(yǔ)從句(3) It + be + 動(dòng)詞的過(guò)去分詞 + 主語(yǔ)從句(4) It + 不及物動(dòng)詞 (seem,appear,turn out. +主語(yǔ)從句(5) lt+及物動(dòng)詞+賓語(yǔ)+主語(yǔ)從句It is not surprising

5、that Shang Hai is an international citylt is still question when we shall have sports meetinglt is unknown which team will win the game另注意在主語(yǔ)從句中用來(lái)表示驚奇、 不相信、 惋惜、 理應(yīng)如此等語(yǔ)氣時(shí)， 謂語(yǔ)動(dòng) 詞要用虛擬語(yǔ)氣“(should)+do,常用的句型有：It is n ecessary (importa nt, n atural, stra nge, etc.) thatIt is a pity (a shame, no won der, etc

6、.) thatIt is suggested (requested, proposed, desired, etc.) that5)注意：1.連詞 that, whether, because(句首)在從句中不擔(dān)任句子成分，只起 連接作用，不能省略。并且 whethe 引導(dǎo)主語(yǔ)從句時(shí)不能用 if 代替。Whether there is life on the moon is an in terest ing questio n.月球上有沒(méi)有生命是個(gè) 有趣的問(wèn)題。2. who, which, how, whe n, where, why 在所引導(dǎo)的主語(yǔ)從句中可擔(dān)任主 語(yǔ)，賓語(yǔ)，狀語(yǔ)，不能省略?？?/p>

7、以用形式主語(yǔ) it 引導(dǎo)。3. who, whom, which, what 等可以和 ever 構(gòu)成合成詞，可引導(dǎo)名從和讓步 狀從。此類主語(yǔ)從句不能用 it 引導(dǎo)，引導(dǎo)詞在句中擔(dān)任句子成分，不能省略。 而 no matter -ever 只能引導(dǎo)讓步狀語(yǔ)從句。4. 句中使用陳述句語(yǔ)序，注意有和虛擬語(yǔ)氣聯(lián)系之處(二 ). 賓語(yǔ)從句 用作賓語(yǔ)的從句叫賓語(yǔ)從句。 引導(dǎo)賓語(yǔ)從句的關(guān)聯(lián)詞與引導(dǎo)主語(yǔ)從句表語(yǔ)從句的 關(guān)聯(lián)詞大致一樣，在句中可以作謂語(yǔ)動(dòng)詞或介詞及非謂語(yǔ)動(dòng)詞的賓語(yǔ)。1)由連接詞 that 引導(dǎo)的賓語(yǔ)從句由連接詞 that 引導(dǎo)賓語(yǔ)從句時(shí)，that 在句中不擔(dān)任任何成分，在口語(yǔ)或非正式的 文體中

8、常被省去，但如從句是并列句時(shí)，第二個(gè)分句前的 that 不可省。例如：He has told me that he will go to Shanghai tomorrow.We must never think (that) we are good in everything while others are good in nothing.注意 ：在 insist, order、command、suggest、advise, propose, desire, request, require,dema nd, decide等表示要求、命令、建議、決定等意義的動(dòng)詞后，賓語(yǔ)從 句常用“(sho

9、uld)+動(dòng)詞原形”例如：I insist that she (should) do her work alone.The commander ordered that troops (should) set off at once.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(yǔ)從句相當(dāng)于特殊疑問(wèn)句，應(yīng)注意句子語(yǔ)序要用陳 述語(yǔ)序。例如： I want to know what he has told you.She always thinks of

10、how she can work well.She will give whoever needs help a warm support.3)用 whether 或 if 引導(dǎo)的賓語(yǔ)從句，其主語(yǔ)和謂語(yǔ)的順序也不能顛倒，仍保持 陳述句語(yǔ)序。此外，whether 與 if 在作 是否”的意思講時(shí)在下列情況下一般只能 用 whether，不用 if:a. 引導(dǎo)主語(yǔ)從句和表語(yǔ)從句時(shí) ；b. 引導(dǎo)從句置于句首時(shí) ；c . 引導(dǎo)從句作介詞 賓語(yǔ)時(shí)；d.從句后有“ornot 時(shí)；e.后接動(dòng)詞不定式時(shí)。例如： Whether there is life on the moon is an interesti

11、ng question.Everything depends on whether we have enough money.4)注意賓語(yǔ)從句中的時(shí)態(tài)呼應(yīng)1)當(dāng)主句動(dòng)詞是現(xiàn)在時(shí)，從句根據(jù)自身的句子情況，而使用不同時(shí)態(tài)例如：He studies English every day.（從句用一般現(xiàn)在時(shí)）He studied English last term.（從句用一般過(guò)去時(shí)）I know （that） he will study En glish next year.（從句用一般將來(lái)時(shí)）He has studied En glish si nee 1998.（從句用現(xiàn)在完成時(shí)）（2）當(dāng)主句動(dòng)詞

12、是過(guò)去時(shí)態(tài)（could, would 除外）,從句則要用相應(yīng)的過(guò)去時(shí)態(tài)， 如一般過(guò)去時(shí)，過(guò)去進(jìn)行時(shí)，過(guò)去將來(lái)時(shí)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(shí)態(tài)。例如：The teacher told us that Tom had left us for America5）th ink, believe, imagi ne, suppose 等等動(dòng)詞引起的否定性賓語(yǔ)從句中，要把上述 主句中的動(dòng)詞變?yōu)榉穸ㄊ健＜磳木渲械姆穸ㄐ问揭频街骶渲校捶穸ㄇ爸茫?。例如?We don t think you are here.I don t believe he will do so.

13、I dont suppose he cares, does he提示：在下列情況下，賓語(yǔ)從句不否定轉(zhuǎn)移：1. think 等詞前有副詞和表示強(qiáng)調(diào)的 doI really expect he wont fail the exam in ati on.我真希望他不會(huì)不通過(guò)考試。I do thi nk that he is not fair.我確實(shí)認(rèn)為他是不公正的。2. think 等詞和其他詞構(gòu)成并列謂語(yǔ)I thi nk and hope that he wo nt cheat at cards 我想，也希望他打牌不會(huì)作弊的。3. think 等詞作為插入語(yǔ)His decision is not

14、wise, I thi nk.我覺(jué)得他的決定并不明智。注意：含有賓語(yǔ)從句復(fù)合句的反意疑問(wèn)句1當(dāng)主句的主語(yǔ)不是第一人稱時(shí)，疑問(wèn)句部分與主句一致，謂語(yǔ)動(dòng)詞是think等詞時(shí)，不存在否定轉(zhuǎn)移的問(wèn)題。He said they were going to help me, did nt heYou dont think we can speak English, do youHe thinks hes got the right an swer, doesnt he2當(dāng)主句的主語(yǔ)為第一人稱，反意疑問(wèn)句應(yīng)與賓語(yǔ)從句保持一致。謂語(yǔ)動(dòng)詞是thi nk, believe, con sider, imag ine

15、, suppose, hope 等詞時(shí)，特別要注意否定轉(zhuǎn)移的問(wèn) 題。I suppose youre serious, arent you （不可用 dont I）I dont suppose hes serious, is h?（不可用 do I）（三）表語(yǔ)從句 在句中作表語(yǔ)的從句叫表語(yǔ)從句。引導(dǎo)表語(yǔ)從句的關(guān)聯(lián)詞與引導(dǎo)主語(yǔ)從句的關(guān)聯(lián) 詞大致一樣，表語(yǔ)從句位于連系動(dòng)詞后，用 that，whether，as, as if 引導(dǎo)；who, which，what 做成分；when，where, how，why。其基本結(jié)構(gòu)為：主語(yǔ) +系動(dòng) 詞+主語(yǔ)從句。例如：The fact is that we ha

16、ve lost the game.That is why he didn t come to the meeting.It looks as if it is going to rain.需要注意的，當(dāng)主語(yǔ)是 reason 時(shí)，表語(yǔ)從句要用 that 弓丨導(dǎo)而不是 because 例如：The reas on why he was late wasthat he missed the train by one mi nute this morni ngThis/That/It is becaus（that）.; I think it is because you are doing too m

17、uch because 只能引導(dǎo)表語(yǔ)從句，只能存在這個(gè)句型中）（四）.同位語(yǔ)從句同位語(yǔ)從句說(shuō)明其前面的名詞的具體內(nèi)容。同位語(yǔ)從句通常由that 引導(dǎo)，who,which，what 做成分；when，where，how，why 做連接副詞?？捎糜谕徽Z(yǔ)從句 的名詞有 advice、dema nd doubt、fact、hope、idea、in formatio n、message n ews order、problem、promise、questionrequestsuggestion truth、wish、word、story 等。例如：The n ews that we won the ga

20、用；而 what 在名詞性從句中不僅起連接作用，而且充當(dāng)句子成 分。句子的意思是： 我們得不到的似乎比我們已經(jīng)擁有的要好。 此題考查了兩個(gè) 名詞性從句：主語(yǔ)從句和賓語(yǔ)從句， what 在這兩個(gè)名詞性從句中都作賓語(yǔ)。 考點(diǎn)之二：考查 it 作形式主語(yǔ)或形式賓語(yǔ)2._ is a fact that English is being accepted as an international language.A.

Where分析：句意為：我們明天是否去野營(yíng)要看天氣而定。 whether 與 if 的區(qū)別是： 在 引導(dǎo)賓語(yǔ)從句時(shí)兩者可以互換，但在引導(dǎo)主語(yǔ)從句、表語(yǔ)從句和同位語(yǔ)從句時(shí)，以及介詞后面的賓語(yǔ)從句或后面緊跟 or not 時(shí)，常用 whether , 而不用 if5.
