1)作不可數(shù)名詞,作“疑惑;懷疑”①必定句中doubt多接whether(普通不用if代替)同位語從句。如:There'ssomedoubt________he'llkeephispromise.他會不會信守諾言還難說。Shehadherdoubts________thenewbookwouldsellwell.她懷疑新書是否會暢銷。whetherwhether43/84②否定句中doubt多接that同位語從句。如:Thereisnodoubt______theywillaskyouforhelp.毫無疑問,他們會請你幫忙。Ihavenodoubt______youwillsucceed.我毫不懷疑你會成功。2)作及物動詞慣用于以下句型中,作“懷疑;不能必定;不大相信”解,普通不用進行時態(tài)。thatthat44/84①用于否定句或疑問句,后接that引導(dǎo)賓語從句。如:Idon'tdoubt______heistellingthetruth.我毫不懷疑他在講真話。Doyoudoubt______hewillwinthematch?你懷疑他會贏這場比賽嗎?②用于必定句,普通接whether或if引導(dǎo)賓語從句。如:Idoubt__________wewillmakeaprofitoutofit.我認為我們不可能從此事中贏利。Wedoubt__________shewillbepersuaded.我們不知道她會不會被說服。

whether/ifwhether/ifthatthat45/84[考點1]Thereisnodoubtthat...是固定句型,意為“毫無疑問……”,that引導(dǎo)是同位語從句，用來深入補充說明doubt詳細內(nèi)容。如：Someresearchersbelievethatthereisnodoubt___acureforAIDSwillbefound.(廣東)A.whichB.that C.what D.whetherB46/84[考點2]itis...that...組成強調(diào)句型,強調(diào)是主語humanactivity。強調(diào)句型可強調(diào)主語、賓語或狀語。如：Itisnotwhoisrightbutwhatisright____isofimportance.(重慶)A.whichB.it C.that D.this解析:將itis和that去掉后,此句成為Notwhoisrightbutwhatisrightisofimportance,句子完整,故此題是一個強調(diào)句型。B47/84Idon’tmindhercriticizingme,but______ishowshedoesitthatIobjectto.(江西)A.it B.that C.this D.which解析:去掉itis和that后,本句相當(dāng)于...,butIobjecttohowshedoesit,是個完整句子。故此句是it強調(diào)句型,被強調(diào)部分是賓語從句。A48/844.phenomenon

這是一個含蓄虛擬條件句。有時假設(shè)情況并不以條件從句形式表示出來,而是經(jīng)過一個介詞短語或其它方式表示。慣用詞或短語有:without,butfor,butthat,otherwise,or,but等。52/84e.g.Withoutyourhelp(=Ifwehadnothadyourhelp),wecouldnothavesucceeded．要是沒有你幫助,我們是不會成功。Hefeltverytiredyesterday,orhewouldhaveattendedtheparty．他昨天很累,不然他就參加那個聚會了。53/84Butforelectricity(=Iftherewerenoelectricity),therewouldbenomodemindustry．要是沒有電,就不會有當(dāng)代工業(yè)。Hewashavingameetingwithhisstudents,otherwise

大量quantitiesof

大量Thereisasmallquantityofwaterleftinthebottle.瓶子里還剩下少許水。Shehasquantitiesofgoodclothes.她有許多好衣服。55/84尤其提醒aquantityof后可接不可數(shù)名詞或可數(shù)名詞復(fù)數(shù)形式。當(dāng)它修飾名詞作主語時,謂語名詞用單數(shù);而quantitiesof后一樣可接不可數(shù)名詞或可數(shù)名詞復(fù)數(shù)形式,但謂語用復(fù)數(shù)。amountsof+不可數(shù)名詞充當(dāng)句子主語時,其謂語動詞用復(fù)數(shù)。56/848.goup

另首先I’dliketoeatout,butontheother

handIshouldbetryingtosavemoney.Iwanttogototheparty,butontheotherhandIoughttobestudying.我想去參加聚會,但從另首先來說,我應(yīng)該留下來學(xué)習(xí)。65/8412.oppose

反對某事/做某事beopposedtosth./doingsth.

反對某事/做某事oppose后若接動詞,則用其動名詞形式，而不用動詞不定式。66/84opposedoingsth.=objecttodoingsth.

反對做某事Theyoungmanopposed/objectedtoturningtohisparentsforhelp.這個年輕人反對向他父母求援。易混辨析oppose(尤指采取行動)反對,反抗(某事)beopposedto首先相當(dāng)于beagainst“反對”;另首先相當(dāng)于beoppositeto“相對”。67/8413.consequencen.結(jié)果,后果,影響inconsequence所以asaconsequence結(jié)果asaconsequenceof因為…結(jié)果Itrainedyesterdayandinconsequencethematchwascanceled.Hestudiedhard,andinconsequencehepassedtheexam.68/84+n.14.state+that從句+wh-從句；他已公開申明他會支持那項政策。Hehaspublicly_________________forthepolicy.statedhissupport我聽見那位官員說不接納兒童。Iheardtheofficialstate
