表語(yǔ)從句解說及專項(xiàng)練習(xí)觀點(diǎn)：表語(yǔ)從句是在復(fù)合句中作表語(yǔ)的名詞性從句。放在系動(dòng)詞以后,一般構(gòu)造是“主語(yǔ)+系動(dòng)詞+表語(yǔ)從句”能夠接表語(yǔ)從句的連系動(dòng)詞有be,look,remain,seem等。Thetroubleisthatweareshortofmoney.困難是我們資本欠缺?！颰hatiswhystonewallsareusedinsteadoffencesaroundNewEnglandfields.這就是為何在新英格蘭用石頭墻而不用柵欄的原由?！顰tthattime,itseemedasifIcouldn'tthinkoftherightwordanyhow.當(dāng)時(shí),我仿佛怎么也想不出一個(gè)適合的字眼來(lái)。指引表語(yǔ)從句的詞：附屬連詞that、whether、asthough、asif（That指引表語(yǔ)從句時(shí)，在口語(yǔ)中，間或能夠省略。）關(guān)系代詞

who,what,which,whom,whose,whatever,whoever,whomever,whichever

等；關(guān)系副詞

when,where,why,how,however,whenever,wherever

等?！筛綄龠B詞that，whether指引的表語(yǔ)從句。that在指引表語(yǔ)從句時(shí)無(wú)詞義，而whether有詞義，意為、“能否”。這時(shí)主句的主語(yǔ)經(jīng)常是些抽象名詞，如question(問題)，trouble(麻煩)，problem(問題)，result(結(jié)果)，chance(可能性)，suggestion(建議)，idea(想法)，reason(原由)等。表語(yǔ)從句對(duì)主句主語(yǔ)進(jìn)行說明、解說，使主語(yǔ)的內(nèi)容詳細(xì)化。比如：★Thetroubleis(that)shehaslosthismoney.麻煩的事是他丟了錢?！颰hequestioniswhetherweneedmoreicecream.問題是我們能否還需要一些冰淇淋。Theproblemwasthatitwastoovaluableforeverydayuse.問題是它作為平時(shí)之用太貴重了。Whatshecouldn’tunderstandaswthatfewerandfewerstudentsshowedinterestinherlessons.我們不可以理解愈來(lái)愈少的學(xué)生對(duì)他的課不感興趣?！申P(guān)系代詞指引的表語(yǔ)從句。關(guān)系代詞who,what,which,whom,whose,whatever,whoever,whomever,whichever等指引表語(yǔ)從句，在句中作主語(yǔ)、賓語(yǔ)、表語(yǔ)，關(guān)系代詞不可以省略。比如：Thequestioniswhichofusshouldgo.問題是我們哪一個(gè)應(yīng)當(dāng)去。Theproblemwaswhocoulddothework.問題是誰(shuí)能做這項(xiàng)工作。That'swhatheisworryingabout.那就是他在擔(dān)憂的事。That'swhatweshoulddo.那是我們應(yīng)當(dāng)做的。※由關(guān)系副詞指引的表語(yǔ)從句。關(guān)系副詞when,where,how,why除在句子起連結(jié)作用外，在從句中還充任時(shí)間，地址，方式或原由狀語(yǔ)，自己擁有詞義。比如：★Goandgetyourcoat.It'swhereyouleftit.去把雨衣拿來(lái)。就在你本來(lái)放的地方。★Ihadneitheraraincoatnoranumbrella.ThatwhyIgot’swetthrough.我們既沒傘也沒雨衣，這是我們淋濕的原由。Thatishowmiceruinmanystoresofgraineveryyear.那就是老鼠是如何每年傷害大批糧食的。Thatiswhatheisworriedabout.那就是他所擔(dān)憂的?！蛇B詞because，asif/asthough等指引的表語(yǔ)從句。Itlookedasifitwasgoingtosnow.看起來(lái)仿佛要下雪了。That'sbecauseweneverthoughtofit.這是由于我們從未想過此事。Itseemsasifhedidn’tknowtheanswer仿佛他不.知道答案。注意表語(yǔ)從句必定要用陳說語(yǔ)序。False:Thequestioniswhencanhearriveatthehotel.Right:Thequestioniswhenhecanarriveatthehotel.B.不可以夠用if，而用whether連結(jié)表語(yǔ)從句(asif例外）。指引賓語(yǔ)從句時(shí)能夠交換if/whether位于介詞后要用whether位于句首時(shí)要用whether。指引表語(yǔ)從句，主語(yǔ)從句，同位語(yǔ)從句時(shí)要用whether。False:Thequestionisiftheenemyismarchingtowardsus.Right:Thequestioniswhethertheenemyismarchingtowardsus.Right:Itlookedasifhehadunderstoodthisquestion.C.不像賓語(yǔ)從句，在有表語(yǔ)從句的復(fù)合句中，主句時(shí)態(tài)和從句時(shí)態(tài)能夠不一致。Right:ThequestioniswhowilltravelwithmetoBeijingtomorrow.Right:Thequestioniswhyhecriedyesterday.D.that在表語(yǔ)從句中不可以夠免卻?；居梅ū碚Z(yǔ)從句只好置于主句以后，而主句的動(dòng)詞只好是聯(lián)系動(dòng)詞。名詞性從句在be等系動(dòng)詞后作表語(yǔ)時(shí)被稱為表語(yǔ)從句比如：Theproblemishowwecangetthethingsweneed.問題是我們?nèi)绾文芘轿覀冃枰臇|西。(how在表語(yǔ)從句中充任方式狀語(yǔ))★ThescissorsarenotwhatIneed.這把剪刀不是我所需要的。(what在表語(yǔ)從句中充任賓語(yǔ))★WhatItoldhimwasthatIwouldfindhimagoodplay.我告訴他的是我會(huì)給他找個(gè)好劇本。(what在主語(yǔ)從句中作直接賓語(yǔ)，that作為表語(yǔ)從句的指引詞在該表語(yǔ)從句中不充任句子成分，不可以省略)★
