同位語從句【語境展示】觀察下面句子，并試著歸納同位語從句的用法要點(diǎn)。1.Thereisageneralbeliefthatthingswillsoongetbetter.2.Thefactthatwedidn'twinwhenweweresocloseisverydisappointing.3.Thereisnotmuchhopethattheyarestillalive.4.There'salwaysapossibilitythathemightgobacktoSeattle.5.ThethoughtthatImightnothaveajobnextyearisabittroubling.6.ImadeapromisethatIwouldn'ttellanyoneaboutthat.7.I'mnotsurewheremynecklaceis,butIhaveaprettygoodideawhotookit.8.Shehadherdoubtswhetherhewouldhelpher.9.Shedoesn'thaveanyideawherethey'vegone.10.Ihavenoideawhythetelevisionisn'tworking.11.BobgotthenewsfromMarythatthesportsmeetinghadbeenputoff.12.Wordcamethatourdutieswouldbechanged.【自我歸納】在主從復(fù)合句中，用作同位語的從句，叫同位語從句（句1句12）。一、同位語從句一般跟在某些抽象名詞后面，如belief,fact,hope,possibility,thought,promise,idea,doubt,news,word等，用以說明或解釋該名詞的具體內(nèi)容（句1句12）。二、同位語從句通常由that引導(dǎo)，that不在從句中充當(dāng)成分，一般不能省略（句1句6）；同位語從句也可以由________,whether,where,why等引導(dǎo)（句7句10）。三、同位語從句有時(shí)可以不緊跟在它所解釋的名詞后面，而是被別的詞隔開，以使整個(gè)句子的結(jié)構(gòu)顯得平衡（句11、句12）?！就卣埂?.suggestion,order,request,requirement等表示建議、命令、要求等含義的名詞后的同位語從句中謂語動(dòng)詞要用“should+動(dòng)詞原形”，其中should可以省略。如：Theydidn'tlikemysuggestionthatwe(should)allsharethecost.Hegaveordersthatthework(should)bestartedimmediately.Sheleftheraddresswitharequestthatanymail(should)besentontoher.Itisalegalrequirementthatyou(should)haveinsuranceforyourcar.2.同位語從句與定語從句的區(qū)別同位語從句相當(dāng)于名詞，與其說明的名詞是等同關(guān)系，即說明它前面的名詞的內(nèi)容；而定語從句的作用相當(dāng)于一個(gè)形容詞，與它的先行詞是修飾與被修飾的關(guān)系，即限定它前面的名詞的內(nèi)容，或加以補(bǔ)充說明。如：ThenewsthatMadgehaddiedtookeveryonebysurprise.（同位語從句）Thenewsthatweheardjustnowisencouraging.

（定語從句）引導(dǎo)同位語從句的that是一個(gè)連詞，在從句中不充當(dāng)任何成分；而引導(dǎo)定語從句的that是關(guān)系代詞，除起連接作用外，還在從句中充當(dāng)主語、賓語等。如：Thisevidencesupportstheviewthatthereistoomuchviolenceontelevision.（同位語從句）Theviewsthatareexpressedinthisbookarepurelythoseoftheauthor.（定語從句）【即學(xué)即練】用適當(dāng)?shù)倪B接詞填空。Thefollowingarementsbyaresident(居民),afireofficerandaclimateexpertaboutarecentflood.Resident：Nobodythought1.________floodingthisbadwouldhappenagain,butastheriverlevelrose,wehadtofacethefact2.________we'dhavetoleaveourhomes.Personally,Ithinkfireofficersshouldbeheldwhollyresponsible.3.________ithasbeenrainingheavilyhereforfivedaysshouldhavewarnedthemthatafloodwasing.Theyshouldhavebeenbetterpreparedtohelpus.Fireofficer:Idon'tthink4.________manyresidentssaidisfair.Todayisapublicholiday.Thisis5.________manyofourstaffweren'theretohelpwiththerescue.However,wewarnedresidentsyesterday6.________theymighthavetoleavetheirhouseswithlittlenotice.However,7.________madetheevacuation(疏散)difficultwasthattheywantedtotakelargeamountsofpersonalbelongingswiththem.Ihavenoidea8.________residentsjustthinkit'sallourfireofficers'fault.Climateexpert:Weholdthebelief9.________climatechangeisgoingtoincreasetheriskofflooding,andanumberofstudieshavesuggested10.________winterriverlevelsthroughoutthecountrywillbemuchhigherthaninthepast.Unfortunately,thesituationinthisareaisworsenedbythefact11.________somanytreeshavebeencutdownonthehillsaroundhereandrainwaterflowsmorequicklyintotherivers.Sothere'sarealpossibility12.________
