詞who,whose,whom,whoever,what,which等；連接副詞where,when,whenever,wherever,how,why等。2.有時(shí)用it作形式主語(yǔ)，將主語(yǔ)從句后置,這樣做是

為了避免句子頭重腳輕。常用句型如下：It+be+名詞+that從句It+be+形容詞+that從句It+be+動(dòng)詞的過(guò)去分詞+that從句It+be+不及物動(dòng)詞+that從句【常見(jiàn)錯(cuò)誤展示】下列各句均有一處錯(cuò)誤，請(qǐng)改正并分析錯(cuò)誤的原因。1.Lighttravelsfasterthansoundiscommonknowledge.2.Ifshe’scomingornotdoesn’tmattermuch.Thatthat雖無(wú)詞義但引導(dǎo)主語(yǔ)從句位于句首時(shí)不能省略。Whetherif,whether都可表示“是否”,但if不能引導(dǎo)位于主句之前的主語(yǔ)從句，它可以引導(dǎo)位于主句之后帶有形式主語(yǔ)it的主語(yǔ)從句。3.Thattheprofessorsaidisofgreatimportance.4.Wherewillthetreesbeplantedhasnotbeendecided.Whatthat引導(dǎo)主語(yǔ)從句時(shí)無(wú)詞義。Whattheprofessorsaid表示“教授所說(shuō)的”。將will置于trees之后。主語(yǔ)從句要用陳述句語(yǔ)序。5.Nomatterwhobreakstherulewillbepunished.6.Whenandwherethemeetingwillbeheldstillremainsaquestion.引導(dǎo)讓步狀語(yǔ)從句時(shí)二者可互換，但引導(dǎo)名詞性從句時(shí)只能用whoever。Whoever主語(yǔ)從句表示單一概念時(shí)，謂語(yǔ)要用單數(shù)形式。remain7.Whatwereyourproblemsayearagohasnowbecomemine.8.Itwasrequestedthateveryonemadeaspeechatthemeeting.has要改為have。主語(yǔ)從句表示復(fù)數(shù)概念時(shí)，謂語(yǔ)要用復(fù)數(shù)形式。have在“Itisrequested/ordered/suggested+that從句”中，從句要用虛擬語(yǔ)氣，即謂語(yǔ)用“should+動(dòng)詞原形”，should可省略。(should)make（2011江蘇卷）Itwasneverclear_______themanhadn’treportedtheaccidentsooner.A．that B．how C．when D．why【解析】考查名詞性從句。這里的it是形式主語(yǔ)，真正的主語(yǔ)是“_____themanhadn'treportedtheaccidentsooner.”根據(jù)句意，原句要表達(dá)的是“為什么這個(gè)老人沒(méi)有立馬報(bào)案這件事還未查明。”所以正確答案為D。2.（2011湖南卷）Beforeaproblemcanbesolved,itmustbeobvious_______theproblemitselfis.A．what B．that C．which D．why

【解析】考查名詞性從句。主語(yǔ)從句缺少表語(yǔ)，故用what。句意：在解決問(wèn)題之前，一定要弄清楚問(wèn)題是什么。3.（2011北京卷）__________BarbaraJonesofferstoherfansishonestyandhappiness.A.Which B.What C.That D.Whom【解析】考查名詞性從句。句意：這個(gè)驚人的消息使我意識(shí)到我們將面臨多么嚴(yán)重的問(wèn)題。結(jié)合句意可知答案為A，此處what引導(dǎo)的賓語(yǔ)從句是一個(gè)感嘆句。4.（2011江西卷）Thevillagershavealreadyknown______we’lldoistorebuildthebridge.A.this B.that C.what D.which【解析】考查賓語(yǔ)從句和主語(yǔ)從句。句意：村民們已經(jīng)知道我們將要做的事情是重建這座橋。后面的賓語(yǔ)從句的主語(yǔ)從句中缺少主語(yǔ)且指物，所以選what。5.（2010北京卷）Somepeopleregardasadrawbackisseenasaplusbymanyothers.A.WhetherB.WhatC.ThatD.How【解析】考查主語(yǔ)從句。句意：一些人眼中的缺點(diǎn)是別人眼中的優(yōu)點(diǎn)。從句中缺賓語(yǔ)，只能用B.what來(lái)引導(dǎo)；C.中的That引導(dǎo)主語(yǔ)從句不做成分。6.（2010浙江卷）Itisuncertain

sideeffectthemedicinewillbringabout,althoughabouttwothousandpatientshavetakenit.A．that B．what C．how D．whether答案：B考點(diǎn)：本題考查主語(yǔ)從句的引導(dǎo)詞。解析：根據(jù)句意：盡管大約有兩千名病人服用過(guò)這種藥物，但是，它會(huì)帶來(lái)什么樣的副作用還不確定。sideeffect意思是“副作用”，還原主語(yǔ)從句中的主干是themedicinewillbringabout______sideeffect。故選擇what，形容詞“什么樣的”，起修飾作用。7．（2010浙江卷）—Howaboutcampingthisweekend,justforachange?—OK,

youwant.A．whichever B．however C．whatever D．whoever答案：C考點(diǎn)：本題考查引導(dǎo)詞。解析：句意：“這個(gè)周末野營(yíng)怎么樣，來(lái)點(diǎn)新鮮的？”“好啊，按你的意思吧！”根據(jù)語(yǔ)境分析出后者支持前面的提出的觀點(diǎn)。8．（2010浙江卷）Itisuncertain

sideeffectthemedicinewillbringabout,althoughabouttwothousandpatientshavetakenit.A．that B．what C．how D．whether答案：B考點(diǎn)：本題考查主語(yǔ)從句的引導(dǎo)詞。解析：根據(jù)句意：盡管大約有兩千名病人服用過(guò)這種藥物，但是，它會(huì)帶來(lái)什么樣的副作用還不確定。sideeffect意思是“副作用”，還原主語(yǔ)從句中的主干是themedicinewillbringabout______sideeffect。故選擇what，形容詞“什么樣的”，起修飾作用。9．(2009天津卷)Itisobvioustothestudents______theyshouldgetwellpreparedfortheirfuture.A．a(chǎn)sB．whichC．whetherD．that解析：選D。句中it為形式主語(yǔ)，that引導(dǎo)的主語(yǔ)從句為真正的主語(yǔ)從句。句意：對(duì)學(xué)生們來(lái)說(shuō)，他們應(yīng)當(dāng)為未來(lái)做好充分的準(zhǔn)備是很明顯的。10．(2009上海卷)Itisnotimmediatelyclear________thefinancialcrisiswillsoonbeover.A．sinceB．whatC．whenD．whether解析：選D。這是it作形式主語(yǔ)的名詞性從句。句意：金融危機(jī)是否會(huì)很快結(jié)束不會(huì)立刻明朗的。若主語(yǔ)從句中去掉soon，也可以選C項(xiàng)，即“金融危機(jī)什么時(shí)候會(huì)結(jié)束”。what在從句中沒(méi)法與其他成分搭配；since“自從……以來(lái)”，不合句意。I.根據(jù)下列各句句意及所給單詞的首字母或漢語(yǔ)提示，寫(xiě)出該單詞的正確形式。HerschoolreportshowsthatsheisweakinEnglishand_______(生物).2.Hewantedtobea_______(物理學(xué)家)anddevotehimselftoscientificresearch.biologyphysicist3.Anythingthatisdroppedontheearthfallstowardsthegroundbecauseoftheforceofg______.4.Thecountryhastheworld’sbestc______forwildgrapes.ravitylimateII.用括號(hào)中所給單詞的適當(dāng)形式填空。Shesangtothemusicwithherhandwaving_______(gentle).2.Tohissurprise,thecarsuddenlywentoutofcontroland_______(crash).3.Suddenly,mostsunlightwas__________(blockout),sotheskyatnoonlookedasifitwereatdusk.gentlycrashedblockedoutIII.用適當(dāng)?shù)膯卧~填空，使下列主語(yǔ)從句意思完整。1._______hefinishedwritingthecompositioninsuchashorttimesurprisedusall.2._______________wewillgoforanoutingtomorrowremainsunknown.3.Itisapity______wewon’tbeabletogotothesouthtospendoursummerholidays.ThatWhether/Wherethat4._______sheiscomingornotdoesn’tmattertoomuch.5._______hecamefromstillpuzzlesallofus.6.Ithappened_____Isawhimyesterday.7.Itdoesnotmakeanydifferencetom
