在復(fù)合句中做表語(yǔ)的從句，叫做表語(yǔ)從句。它位于主句的系動(dòng)詞之后，對(duì)主語(yǔ)進(jìn)行解釋說明，使主語(yǔ)的內(nèi)容具體化。三、表語(yǔ)從句的構(gòu)成主語(yǔ)+系動(dòng)詞+引導(dǎo)詞

由that引導(dǎo)，that本身沒有詞義，在句中只起連接作用，不充當(dāng)句子成分,通常不省略。that引導(dǎo)表語(yǔ)從句時(shí)，主句的主語(yǔ)常常是些抽象名詞，如question,trouble,problem,result,chance,suggestion,idea,reason等。1.Thequestionis______________________2.Thequestionis_______________________whetheritisworthdoing.whetherwecanwinthem.2.whether在句子中不充當(dāng)任何成分，但具有“是否”的意義。注意：if不能引導(dǎo)表語(yǔ)從句。Thequestioniswhat

causedtheaccident.Thatmountainisnolongerwhatitusedtobe.Theproblemiswhoseworkisthebest.Thequestioniswhichofusshouldgo.Thequestioniswho(m)weshouldtrust.3.由連接代詞who,what,which,whom,whose,whatever,whoever,whomever,

whichever

引導(dǎo)表語(yǔ)從句，并在句中作主語(yǔ)、賓語(yǔ)、表語(yǔ)，代詞不能省略。4.連接副詞

when,

where,

how,

why

除在句子起連接作用外，在從句中還充當(dāng)時(shí)間、地點(diǎn)、方式或原因狀語(yǔ)，本身具有詞義。Thisiswhy

shewaslateforthemeeting.Thequestionishowhedidit.Thatiswherehewasborn.That’swhereIfirstmether.5.asif/though引導(dǎo)表語(yǔ)從句時(shí)，在句子中不充當(dāng)任何成分，但有意義。譯為：似乎，好像。Helooksasifhewerearichman.Itsoundsasifsomeoneisknockingatthedoor.asif/asthough引導(dǎo)的表語(yǔ)從句如果是事實(shí)，就用陳述語(yǔ)氣，如果與事實(shí)不符，就用虛擬語(yǔ)氣(主句一般現(xiàn)在時(shí)，從句就用一般過去時(shí)。主句是一般過去時(shí)，從句用過去完成時(shí))。Theyoungmanwithlonghairlooksasifhewereagirl.Darkcloudsaregathering.Itlooksasifit’sgoingtorain.1.Iwaslateforschoolthismorning.That'sbecauseIstayeduptoolatelastnight.(果→因)今天早上我上學(xué)遲到了,那是因?yàn)槲易蛲戆疽固砹恕?.Istayeduptoolatelastnight.That'swhy

Iwaslateforschoolthismorning.(因→果)我昨晚熬夜太晚,那就是我今天早上上學(xué)遲到的原因。6.

由because/why引導(dǎo)because引導(dǎo)的表語(yǔ)從句常用于“That'sbecause…”結(jié)構(gòu)中,說明產(chǎn)生上述結(jié)果的原因;why引導(dǎo)的表語(yǔ)從句說明由上述原因?qū)е碌哪撤N結(jié)果。Thereasonwhyhewaslatewasthathemissedthefirstbusthismorning.他遲到的原因是他今天早上沒趕上首班公共汽車。[注意]that,why,because引導(dǎo)的表語(yǔ)從句的區(qū)別:that,why,because都可引導(dǎo)表語(yǔ)從句，表示原因的名詞(reason,cause)作句子主語(yǔ)時(shí),其后的表語(yǔ)從句常用that引導(dǎo),不可用because引導(dǎo)。7.使用虛擬語(yǔ)氣的表語(yǔ)從句當(dāng)主語(yǔ)是表示“建議、命令、要求、計(jì)劃(suggestion,advice,proposal,order,command,request,requirement,demand,plan)”等名詞時(shí),表語(yǔ)從句應(yīng)該用虛擬語(yǔ)氣,即從句謂語(yǔ)用“should+動(dòng)詞原形”形式,should可以省略。

e.g.Mysuggestionisthatwe(should)startearlytomorrow.小結(jié)：1.表語(yǔ)從句的構(gòu)成:引導(dǎo)詞+簡(jiǎn)單句2.引導(dǎo)詞:連詞：that,whether,asif,asthough連接代詞：who,what,which,whose,whatever,whoever,

whichever,

whomever連接副詞：when,where,how,why

3.4個(gè)注意點(diǎn):②if不引導(dǎo)表語(yǔ)從句③主語(yǔ)為reason時(shí)，引導(dǎo)詞用that④語(yǔ)序陳述語(yǔ)序①that引導(dǎo)表語(yǔ)從句時(shí)不能省略【完成句子】thathedidn’treallytry
