hedecidedthatshewasgoingtobeanurse.她決定將來成為一名護士。①that作賓語從句的引導詞時可省略，但當一個句子有兩個或多個并列的賓語從句時，引導第二個和以后幾個從句的that不可省略。Hesaid(that)Mrs.Wangwaskindandthatwecouldturntoherforhelp.他說王太太很善良，我們可以向她求助。Theytoldus(that)therewouldbeameetingthatafternoonandthatweallshouldattendthemeeting.他們告訴我們那天下午會有一個會議，并且我們都應(yīng)該參加這個會議。②在可以接復合賓語的動詞之后,如think,make,consider等，可以用it作形式賓語，而把真正的賓語從句后置，在這種情況下that不能省略。ImadeitclearthatIwasdeterminedtocarryouttheplan.（that不能省略）我已表明決心執(zhí)行這個計劃。Ithinkitapitythatyoucouldnotcome.你不能來，我深深惋惜。③主句謂語和賓語從句之間有插入語時，賓語從句前的that不能省略。Heannounced,believeitornot,thathewouldneverforgiveher.信不信由你，他宣布他絕不會原諒她。④在demand,order,suggest,decide,insist,desire,request,command,doubt等表示要求、命令、建議、決定等意義的動詞后，賓語從句常用“（should）+動詞原形”。Iinsistthatshe(should)doherworkalone.我堅持要她自己工作。Thepolicemandemandedthatthegateshouldbeshut.警察命令把大門關(guān)上。（2）whether/if引導的賓語從句從屬連詞whether/if作“是否”講時，常用在ask,care,findout,know,wonder等動詞（短語）后引出帶有疑問意義的語從句，從句中仍保持陳述語序，whether或if不充當句子分。Idon'tknowif/whetherhewillgotothecinemathisevening.我不知道今晚他是否會去看電影。Doyouknowwhether/ifanydecisionhasbeenarrivedat?你知道是否已經(jīng)做出決定了嗎？以下只能用whether引導賓語從句的情況：①作介詞賓語時，只能用whether引導賓語從句。Ihaven'tsettledthequestionofwhetherI'llgobackhome.我還沒有決定是否回家。Itdependsonwhetheryoucandotheworkwell.那取決于你是否能將工作做好。②whether與or或ornot連用時，不可用if替換。Shedoesn'tknowwhethersheshouldgetmarriednoworwait.她不知道是現(xiàn)在就結(jié)婚還是等等再說。Iwonderwhetherornotweshouldmakeitclearthatwe'velostthisgame.我在想我們是否應(yīng)該說清楚我們已經(jīng)輸了這場比賽。③動詞doubt用于肯定句式，其賓語從句用whether引導。Idoubtverymuchwhetherheiscoming.我非常懷疑他是否要來。Westilldoubtwhetherwhathesaidistrue.我們?nèi)耘f懷疑他說的話是否是真的。（3）連接代詞和連接副詞引導的賓語從句連接代詞who,whom,whose,what,which,whatever,whoever,whomever,whichever和連接副詞when,where,how,why這些連接詞都有詞義，除引導從句外，還在從句中充當一定的成分，可作主語、賓語、表語、定語、狀語等。這種賓語從句有疑問意義，但不是疑問句，不能用疑問語序，而要用陳述語序。Idon'tknowwhatthelittlegirllikes.我不知道這個小女孩喜歡什么。CouldyoutellmewhichjobIshouldtake,please?請你告訴我我應(yīng)該選擇哪種工作，好嗎？5.使用賓語從句應(yīng)注意的幾個問題（1）賓語從句的語序。賓語從句的語序應(yīng)為陳述句的語序，即“主語+謂語+賓語+其他”。CanyoutellmehowIcangetintouchwiththefamousdoctor?你能告訴我怎樣與那位著名的醫(yī)生取得聯(lián)系嗎？（2）賓語從句的時態(tài)。如果主句的時態(tài)是一般現(xiàn)在時，賓語從句可以用相應(yīng)的任何時態(tài)；如果主句的時態(tài)是一般過去時，賓語從句只能用相應(yīng)的過去時態(tài)；如果賓語從句所陳述的是客觀真理，其時態(tài)常用一般現(xiàn)在時。HesaidthathehadbeentoNewYork.（從句是過去完成時）他說他曾去過紐約。Ourteachertoldusthatlighttravelsfasterthansound.（從句陳述的是客觀事實）老師說光比聲音傳播得快。（3）當主句謂語動詞是think,believe,suppose,expect等詞，而賓語從句的意思是否定時，常把否定轉(zhuǎn)移至主句表示。Idon'tthinktheyoungmanwillaccepttheadvice.我認為這個年輕人不會接受這個建議。Idon'tthinkhecanfinishtheworkontime.我認為他無法按時完成工作。（4）有些動詞（短語），如enjoy,love,like,hate,appreciate,take,hide,seeto,insiston,dependon,relyon等帶賓語從句時，習慣上在從句前加形式賓語it。Ihateitwhenpeopleaskmeformoney.我不喜歡別人向我借錢。Iwillappreciateitifyoucangivemeahand.如果你能幫我一把，我會很感激。表語從句在復合句中作表語的從句叫表語從句。表語從句位于主句中的系動詞之后。1.that引導的表語從句連接詞that在從句中只起到連接作用，不作任何成分。ThetroubleisthatIhavelosthisaddress.問題是我把他的地址弄丟了。WhatIparticularlydislikeaboutthislessonisthatitisreallyboring.我特別不喜歡這節(jié)課是因為它的確令人乏味。2.whether引導的表語從句連接詞whether起連接作用，意為“是否；究竟；到底”，在句中不作任何成分。Whathewantstoknowiswhetherwecanfinishourworkbytomorrowmorning.他想要知道的是我們到明天早上能否完成工作。Thequestioniswhetheryoucandotheworkwell.問題是你能否做好這項工作。3.從屬連詞as,asif/though引導的表語從句Itsoundsasifsomeoneisknockingatthedoor.聽起來好像有人在敲門。Thepencilseemsasthoughitwerebrokenwhenitisparlyputinthewater.當把鉛筆的一部分放入水中時，它看上去好像斷了。4.because,why引導的表語從句That'sbecausehedidn'tunderstandme.（That'sbecause…強調(diào)原因）那是因為他沒有理解我。That'swhyhegotangrywithme.（That'swhy...強調(diào)結(jié)果）那正是他對我生氣的原因。注意：reason作主語時，后面的表語從句表示原因時，要用that引導，不宜用because。ThereasonwhyIwassadwasthathedidn'tunderstandme.我難過的原因是他沒有理解我。Thereasonwhyheaskedfortwodays'leaveisthathehadtotakecareofhissickson.他請了兩天假的原因是他要照顧他生病的兒子。5.wh-疑問詞引導的表語從句連接代詞who,whom,whose,what,which,whoever,whatever,whichever和連接副詞where,when,how,why引導的表語從句。Theproblemiswhowecangettoreplaceher.問題是我們能找到誰去替代她。Thequestionishowhedidit.問題是他是如何做這件事的。Theirdifficultyiswheretheycanraiseenoughmoney.他們的困難是他們到哪里能籌到足夠的錢。6.主語是表示建議、命令、要求、計劃（suggestion,advice,order,request,proposal）等的名詞，那么表語從句應(yīng)該用虛擬語氣，即should后接動詞原形，should可以省略。Mysuggestionisthatwe(should)leavethevillagerightnow.我的建議是我們應(yīng)該立刻離開這個村子。Hisrequestisthatthey(should)stayhereforthenight.他請求他們在這里待一晚。同位語從句在復合句中，跟在一個名詞后對其作進一步解釋說明的從句叫同位語從句。能跟同位語從句的名詞有fact,news,idea,truth,doubt,belief,hope,problem,information,wish,promise,answer,possibility,question,evidence,report,explanation,suggestion,conclusion等抽象名詞。There'safeelinginmethatwe'llneverknowwhataUFOis.我有一種感覺，我們永遠都無法知道不明飛行物是什么。Idon'tliketheideathatmoneyiseverything.我不喜歡認為金錢就是一切的觀點。一、同位語從句的連接詞引導同位語從句的詞有連詞that,whether，疑問代詞who,which,what和疑問副詞where,when,why,how等。1.由連詞that,whether引導的同位語從句。that,whether引導從句，但在從句中不作成分，不能省略。that無意義；whether有“是否”之意。Theyheardthenewsontheradioyesterdaythatatyphoonwascoming.昨天他們從收音機里聽到臺風要來的消息。Theproblemwhetherhewillbesentencedfordrunkdrivingisn'tclear.他是否會因酒后駕駛而被判刑這一問題還不清楚。2.由疑問代詞who,which,what引導的同位語從句。疑問代詞在從句中作主語、賓語或定語。Thequestionwhoshouldgoabroadrequiredconsideration.（who在從句中作主語）誰會出國這個問題還需要考慮。IhavenoideawhichoneIshouldchoose.(which在從句中作定語）我不知道該選哪一個。Hehasnoideawhatheshoulddonext.(what在從句中作賓語）他不知道下一步要做什么。3.由疑問副詞when,where,w
