煩），problem（問題），result（結(jié)果），chance（可能性），suggestion（建議），idea（想法），reason（理由）等。表語從句對主句主語進行說明、解釋，使主語的內(nèi)容具體化。例如：★Thetroubleis（that）shehaslosthismoney. 麻煩的事是他丟了錢?！颰hequestioniswhetherweneedmoreicecream. 問題是我們是否還需要一些冰淇淋?！颰heproblemwasthatitwastoovaluableforeverydayuse.問題是它作為日常之用太貴重了。★Whatshecouldn'tunderstandwasthatfewerandfewerstudentsshowedinterestinherlessons. 我們不能理解越來越少的學(xué)生對他的課不感興趣?！申P(guān)系代詞引導(dǎo)的表語從句。關(guān)系代詞who,what,which,whom,whose,whatever,whoever,whomever,whichever等引導(dǎo)表語從句，在句中作主語、賓語、表語，關(guān)系代詞不能省略。例如：★Thequestioniswhichofusshouldgo. 問題是我們哪一個問題是誰能做這應(yīng)該去。問題是誰能做這★ Theproblemwaswhocoulddothework.項工作?！?That'swhatheisworryingabout. 那就是他在擔心的事?！颰hat'swhatweshoulddo.那是我們應(yīng)該做的?！申P(guān)系副詞引導(dǎo)的表語從句。關(guān)系副詞when,where,how,why除在句子起連接作用外，在從句中還充當時間，地點，方式或原因狀語，本身具有詞義。例如：★Goandgetyourcoat.It's whereyouleftit.去把雨衣拿來。就在你原來放的地方?！颕hadneitheraraincoatnoranumbrella.That 'swhyIgotwetthrough.我們既沒傘也沒雨衣，這是我們淋濕的原因。★Thatishowmiceruinmanystoresofgraineveryyear. 那就是老鼠是怎樣每年損害大量糧食的?！颰hatiswhatheisworriedabout.那就是他所擔心的?！蛇B詞because，asif/asthough等引導(dǎo)的表語從句。★Itlookedasifitwasgoingtosnow.看起來好像要下雪了。★That'sbecauseweneverthoughtofit.這是因為我們從未想過此事。★Itseemsasifhedidn'tknowtheanswer.好像他不知道答注意表語從句一定要用陳述語序False:Thequestioniswhencanhearriveatthehotel.Right:Thequestioniswhenhecanarriveatthehotel.不可以用if，而用whether連接表語從句（asif例外）引導(dǎo)賓語從句時可以互換if/whether位于介詞后要用whether位于句首時要用whether。引導(dǎo)表語從句，主語從句，同位語從句時要用whether。False:Thequestionisiftheenemyismarchingtowardsus.Right:Thequestioniswhethertheenemyismarchingtowardsus.Right:Itlookedasifhehadunderstoodthisquestion.不像賓語從句，在有表語從句的復(fù)合句中，主句時態(tài)和從句時態(tài)可以不一致。Right:ThequestioniswhowilltravelwithmetoBeijingtomorrow.Right:Thequestioniswhyhecriedyesterday.that在表語從句中不可以省掉?；居梅ū碚Z從句只能置于主句之后，而主句的動詞只能是聯(lián)系動詞。名詞性從句在be等系動詞后作表語時被稱為表語從句例如：★Theproblemishowwecangetthethingsweneed.問題是我們怎樣能弄到我們需要的東西。（how在表語從句中充當方式狀語）★ThescissorsarenotwhatIneed.這把剪刀不是我所需要的。（what在表語從句中充當賓語）★WhatItoldhimwasthatIwouldfindhimagoodplay.我告訴他的是我會給他找個好劇本。（what在主語從句中作直接賓語，that作為表語從句的引導(dǎo)詞在該表語從句中不充當句子成分，不能省略）★ ThatiswhatIwanttotellyou. 那就是我想要對你講的。（what在表語從句中充當直接賓語）★Thatiswhyshefailedtopasstheexam. 那就是她考試不及格的原因。（why在表語從句中充當原因狀語）表語測試1.Thequestionis wewillhaveoursportsmeetnextweek.thatB.ifC.whenD.whether2．Thereasonwhyhefailedis hewastoocareless.becauseB.thatC.forD.becauseof3.Goandgetyourcoat.It's youleftitA.where B.there C.therewhereD.wherethere4．Theproblemis totaketheplaceofTed
