表語從句講解及專項練

習(xí)答案Documentnumber:PBGCGO^-BTDO-OOaPTTl"8表語從句講解及專項練概念：表語從句是在復(fù)合句中作表語的名詞性從句。放在系動詞之后,一般結(jié)構(gòu)是“主語+系動詞+表語從句”可以接表語從句的連系動詞有be,look,remain,seem等?！颰hetroubleisthatweareshortofmoney.困難是我們資金短缺?！颰hatiswhystonewallsareusedinsteadoffencesaroundNewEnglandfields.這就是為什么在新英格蘭用石頭墻而不用柵欄的原因。★Atthattime,itseemedasifIcouldn'tthinkoftherightwordanyhow.當(dāng)時,我似乎怎么也想不出一個恰當(dāng)?shù)淖盅蹃?。引?dǎo)表語從句的詞：從屬連詞that、whether、asthough、asif（That引導(dǎo)表語從句時，在口語中，間或可以省略。）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?！蓮膶龠B詞that，whether引導(dǎo)的表語從句。that在引導(dǎo)表語從句時無詞義，而whether有詞義，意為、“是否”。這時主句的主語常常是些抽象名詞，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（理由）等。表語從句對主句主語進(jìn)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。Thequestioniswhetherweneedmoreicecream.問題是我們是否還需要一些冰淇淋。Theproblemwasthatitwastoovaluableforeverydayuse.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.問題是我們哪一個應(yīng)該去。Theproblemwaswhocoulddothework.問題是誰能做這項工作。That'swhatheisworryingabout.那就是他在擔(dān)心的事。That'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(dāng)時間，地點(diǎn)，方式或原因狀語，本身具有詞義例如：★Goandgetyourcoat.It'swhereyouleftit.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。Thatiswhatheisworriedabout.那就是他所擔(dān)心的?！蛇B詞because，asif/asthough等引導(dǎo)的表語從句。Itlookedas訐itwasgoingtosnow.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.好像他不知道答案。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（as訐例外）。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(dāng)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(dāng)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(dāng)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(dāng)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(dāng)原因狀語）表語測試1.Thequestioniswewillhaveoursportsmeetnextweek.
