高考英語(yǔ)語(yǔ)法精講精練專(zhuān)題九名詞性從句常考點(diǎn)

專(zhuān)題九名詞性從句常考點(diǎn)在復(fù)合句中起名詞作用的從句叫作名詞性從句。它包括主語(yǔ)從句、賓語(yǔ)從句、同位語(yǔ)從句和表語(yǔ)從句。名詞性從句是英語(yǔ)中的一個(gè)重要語(yǔ)法項(xiàng)目，在歷年的高考中幾乎都涉及到。引導(dǎo)名詞性從句的連接詞可分為三類(lèi)：連接詞that，whether，if(不充當(dāng)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。eq\a\vs4\al(1)Itis...和Thereis...Itis...句型中it為形式主語(yǔ)，真正的主語(yǔ)為動(dòng)名詞、不定式或從句，而Thereis意為“有……”，有時(shí)be也可以用exist，remain等替代。用it，there填空：①________isapitythathewasabsent.②________isafactthathehasliedtoyou.③________isnowonderthatheissoexcited.④________isnoneedtoworryaboutit.⑤________isnosense/point(in)arguingwithhim.⑥________isnodoubtthathehasgone.【答案】①I(mǎi)t②It③It④There⑤There⑥Thereeq\a\vs4\al(2)從句作主語(yǔ)時(shí)的謂語(yǔ)動(dòng)詞形式主語(yǔ)從句作主語(yǔ)相當(dāng)于第三人稱(chēng)單數(shù)作主語(yǔ)，謂語(yǔ)動(dòng)詞用單數(shù)；如果由and連接兩個(gè)或兩個(gè)以上的主語(yǔ)從句作主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞用復(fù)數(shù)；由兩個(gè)或多個(gè)連接詞引導(dǎo)一個(gè)主語(yǔ)從句，謂語(yǔ)動(dòng)詞用單數(shù)。用所給詞的適當(dāng)形式填空：①Thatthepresidentiscoming________(excite)allofus.②Howcloseparentsaretotheirchildren________(have)astronginfluenceontheircharacter.③Whenandwherethemeetingwillbeheld____________(notdecide)yet.【答案】①excites②has③isn'tdecided/hasn'tbeendecidedeq\a\vs4\al(3)賓語(yǔ)從句的時(shí)態(tài)和語(yǔ)序賓語(yǔ)從句中的時(shí)態(tài)要注意呼應(yīng)。當(dāng)主句中的謂語(yǔ)是現(xiàn)在時(shí)，從句根據(jù)自身的句子情況，而使用不同的時(shí)態(tài)。當(dāng)主句中的謂語(yǔ)是過(guò)去時(shí)態(tài)，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)真理、自然現(xiàn)象，則從句仍用現(xiàn)在時(shí)態(tài)。賓語(yǔ)從句語(yǔ)序要用陳述語(yǔ)序(whatis/wasthematter除外)。①Thephotographswillshowyou________．A.whatdoesourvillagelooklikeB.whatourvillagelookslikeC.howdoesourvillagelooklikeD.howourvillagelookslike②Someoneisringingthedoorbell.Goandsee________．A.whoisheB.whoheisC.whoisitD.whoitis③Hello，Ididn'tknowyou________(be)inLondon.Howlonghaveyoubeenhere?④Ithoughthe________(be)comingtomorrow.⑤Theteachertoldusthatlight________(travel)ataveryhighspeed.【答案】①B②D③were④was⑤travelseq\a\vs4\al(4)表語(yǔ)從句中的常見(jiàn)句型常用的句型有：Thereasonisthat...；Itisbecause...；That'swhy...；That'swhere...。完成下列句子：①Thereason________heisabsentfromschoolis________heisill.＝Heisill.That's________heisabsentfromschool.＝Heisabsentfromschool.That's________heisill.②Thereason________hegavewas________hewascaughtinthetrafficjam.③That's________Idisagree/theproblemlies/Ihavedoubt/youaremistaken.That's________Idisagreeabout/theproblemliesin/Ihavedoubtabout/youaremistakenabout.【答案】①why；that；why；because②which；that/不填③where；whateq\a\vs4\al(5)同位語(yǔ)從句和定語(yǔ)從句的辨別同位語(yǔ)從句就是在復(fù)合句中作名詞的同位語(yǔ)的名詞性從句。連接詞that引導(dǎo)同位語(yǔ)從句時(shí)，應(yīng)在某些抽象名詞之后，如：fact，hope，story，thought，suggestion，idea，news，possibility，feeling，doubt，truth，wish，word(消息)，request，information，order，message等，對(duì)前面的名詞起補(bǔ)充說(shuō)明的作用。同位語(yǔ)從句有時(shí)可以不緊跟在它所說(shuō)明的名詞后面，而是被別的詞隔開(kāi)。定語(yǔ)從句中的that是關(guān)系代詞，既起引導(dǎo)從句的作用，同時(shí)又在從句中充當(dāng)主語(yǔ)或賓語(yǔ)，而同位語(yǔ)從句中的that是連詞，只起連接主句與從句的作用，不充當(dāng)句中任何成分。完成下列句子：①Thenews________hetoldusexcitedus.Thenews________ourteamwonthegameexcitedus.②Thefact________hecollectedwassurprising.Thefact________hesaidnothingwassurprising.③Thereisachance/possibility________hewilllosethegame.＝________arethathewilllosethegame.④Informationhasbeenputforward________moremiddleschoolgraduateswillbeadmittedintouniversities.【答案】①that/which/不填；that②that/which/不填；that③that；Chances④thateq\a\vs4\al(6)what和that的用法①what可引導(dǎo)主語(yǔ)從句、賓語(yǔ)從句和表語(yǔ)從句，并且替代名詞性從句中所缺的主語(yǔ)、賓語(yǔ)或表語(yǔ)(尤其注意what引導(dǎo)的從句作介詞賓語(yǔ))，相當(dāng)于“名詞或代詞＋that/which”；另外，what不能引導(dǎo)定語(yǔ)從句。②that在名詞性從句中只引導(dǎo)從句，不充當(dāng)成分。如：Thathesaidnothingatthemeetingsurprisedus.[注]介詞后不接that從句，除了inthat...和exceptthat...。that引導(dǎo)兩個(gè)以上的賓語(yǔ)從句，第一個(gè)that可省略，其后的that都不可省略。that引導(dǎo)主語(yǔ)從句、表語(yǔ)從句和同位語(yǔ)從句時(shí)，that不可省略。完成下列句子：①Theschoolisnolonger________itusedtobe.＝Theschoolisnolongertheone________itusedtobe.②Finallyhetolduseverything________hehadseen.＝Finallyhetoldus________hehadseen.③Theyarrivedin________wasonceaschool.＝Theyarriveintheplace________wasonceaschool.④Don'tcare________othersthinkaboutyou.⑤Doyouknow________theydowithwastepaper?【答案】①what；that②that；what③what；that/which④what⑤whateq\a\vs4\al(7)whether和if的區(qū)別以及whether和that的區(qū)別1.if和whether都可譯為“是否”，兩者引導(dǎo)賓語(yǔ)從句時(shí)通?？梢曰ハ嗵鎿Q。而以下幾種情況中，只能用whether，不能用if：①?gòu)?qiáng)調(diào)兩方面的選擇，特別是句中有ornot時(shí)。如：Letmeknowwhetheryoucancomeornot.②賓語(yǔ)從句前置時(shí)。如：Whetherthisistrue，Ican'tsay.③引導(dǎo)主語(yǔ)、表語(yǔ)、同位語(yǔ)從句時(shí)。如：Whetherthefootballgamewillbeplayeddependsontheweather.(主語(yǔ)從句)Thequestioniswhetherhecandoit.(表語(yǔ)從句)Thequestionwhetherweshouldgowiththemmustbedecidedatonce.(同位語(yǔ)從句)④在介詞之后作賓語(yǔ)時(shí)。如：Ihaven'tsettledthequestionofwhetherI'llgobackhome.Whetherwewillgotheredependsonwhetheritisgoingtorain.⑤在不定式前與不定式一起組成短語(yǔ)時(shí)。如：Whethertogoorstayisstillaquestion.[注]if可以引導(dǎo)條件狀語(yǔ)從句，有“假如；如果”之意，而whether可以引導(dǎo)讓步狀語(yǔ)從句，有“不管；無(wú)論”之意。如：Ifyouaskhim，hewillhelpyou.Whetherhecomesornot，wewillbeginourpartyontime.2.whether和that的區(qū)別：that表示事實(shí)，而whether表示疑問(wèn)。完成下列句子
