一什么是賓語從句？試比較賓語從句的概念

在句子中起賓語作用的從句叫做賓語從句。

WeknowMrGreenteachesEnglish.Sheaskediftheseanswerswereright.二、賓語從句三要素：連接詞時(shí)態(tài)語序不同連接詞引導(dǎo)的賓語從句1.由從屬連詞that引導(dǎo)的賓語從句3.由連接代詞who,whom,whose,which，

what和連接副詞where,how,why,when引導(dǎo)的賓語從句2.由從屬連詞whether,if引導(dǎo)的賓語從句賓語從句連接詞:1.陳述句2.一般疑問句3.特殊疑問句thatif/whether原有的連接代詞和連接副詞1.Ihear(that)_______________________.2.Hesaid(that)______________________.3.Theteachertoldus(that)_______________________________.

hewillbebackinanhour

hemissedusverymuch

theearthmoves由that引導(dǎo)的賓語從句注：that在句中無詞匯意義，在從句中不充當(dāng)成分，在口語當(dāng)中往往省略。aroundthesunObjectclauseswiththatWe’llhaveexamsnextFriday.UsingsayIcanhelphim.Theteachersays(that)we’llhaveexamsnextFriday.Thegirlsays(that)shecanhelphim.1.Aprilisthehottestmonthoftheyear.(Ibelieve…)Ibelieve(that)Aprilisthehottestmonthoftheyear.

2.Itwasalittlecrowded.(Iguess…)

Iguess(that)itwasalittlecrowded.3.Theraceswerenotthatinterestingtowatch.(Billthinks…)Billthinks(that)theraceswerenotthatinterestingtowatch.4.TheWaterFestivalisreallyfun.(Iknow…)

Iknow(that)theWaterFestivalisreallyfun.5.MissLiuwillgotothebeachtomorrow.(Ihear…)Ihear(that)MissLiuwillgotothebeachtomorrow.6.Thefoodwasdelicious.(Hesays…)

Hesays（that)thefoodwasdelicious.連詞that不能省略的幾種情況在由that引導(dǎo)的賓語從句中，由于連詞that只起引導(dǎo)功能，無具體意義，不擔(dān)當(dāng)任何成份，因此在口語或非正式的文體中常可省略。然而，大凡規(guī)則總有例外的情況，在下列that引導(dǎo)的賓語從句中，that則不能省略。1.從句的主語是that。如：

Hesaysthatthatisarealking’shat.

他說那是一個真的王冠。2.that從句中含有主從復(fù)合句。如：

I’mafraidthatifyou’velostit,youmustpayforit.3.主、從句之間有插入語時(shí)。如：

Itsayshere,onthiscard,thatitwasusedinplays.

卡片上寫著，它是古代演戲用的。4.若出現(xiàn)兩個或兩上以上的由that引導(dǎo)的賓語從句，且由并列連詞連接時(shí)，只有第一個連詞that可以省略。如：

Shesaid(that)shewouldcomeandthatshewouldalsobringherson.

她說她要來，還要帶她的兒子來。TheseplanetwillproducefoodandoxygenthatweneedtoliveonMars.ScientistswilldevelopplantsthatcangrowonMars.PeoplethinkthathumansonMarshavetowearspecialbootstomakethemselvesheavier.WeallknowthatMarsisaplanetinthesolarsystem.ThejourneytoMarscouldtakeonlyaveryshorttimeinspaceshuttlesthattravelathalfthespeedoflight.SomescientistsdonotbelievethatthejourneytoMarswillbeverycomfortable.Whichofthefollowingsentenceshasanobjectclause?√√√IsJimin?Hasshetakenanymedicine?UsingwonderLiLeiwondersifJimisin.Thedoctorwondersifshehastakensomemedicine.疑問句變賓語從句的步驟：1、把句子變?yōu)榭隙ň銲sJimathome?

Jimisathome.

2.IsJuneagoodtimetovisitHongKong?JuneisagoodtimetovisitHongKong.

3.Doeshelikesports?Helikessports.

4.Willtheyplaybasketballafterschool?Theywillplaybasketballafterschool.變化方法：主句+if/whether+一般疑問句。if/whether引導(dǎo)賓語從句，表示“是否”之義，在句中不充當(dāng)句子成份，if/whether可互換。2.在句子前加上從屬連詞whether,if該一般疑問句要變?yōu)殛愂鼍湫问?。把下列各句變?yōu)橘e語從句IsJimathome?(Iwonder…)

Iwonderwhether/ifJimisathome.

2.IsJuneagoodtimetovisitHongKong?(Hewonders…)

Hewonderswhether/ifJuneisagoodtimetovisitHongKong.

把下列各句變?yōu)橘e語從句

3.Doeshelikesports?(Doyouknow…)Doyouknowwhetherhelikessports?

4.Willtheyplaybasketballafterschool?(Heasks…)Heaskswhethertheywillplaybasketballafterschool.Ⅰ.if和whether引導(dǎo)賓語從句時(shí)，作“是否”講，一般情況下，二者沒有區(qū)別，可以換用。但if常用于口語中，whether比較正式。如：

Millieaskedif/whetherhelikedthissweater.

米莉問他是否喜歡這件羊毛衫。

Thefishermanwantstoknowif/whetheritwillrain.

漁民想知道天是否會下雨。Objectclauseswithifandwhether由if/whether引導(dǎo)的賓語從句Ⅱ.if和whether引導(dǎo)賓語從句時(shí)，要注意賓語從句三要素，即連詞、語序和時(shí)態(tài)。由于if和whether連接的是一般疑問句，因此要注意把從句語序改為陳述句語序。如：

DoesMrZhaoliveinRoom208?Couldyoutellme?→Couldyoutellmeif/whetherMrZhaolivesinRoom208?其次要注意時(shí)態(tài)變化：

1.若主句是一般現(xiàn)在時(shí)，從句用任何所需時(shí)態(tài)。如：

Hewantstoknowif/whethertheyhadagoodjourneyhome.

他想知道他們回家旅途是否愉快。2.若主句是一般過去時(shí)，從句則用跟過去相關(guān)的時(shí)態(tài)。即一般現(xiàn)在時(shí)變?yōu)橐话氵^去時(shí)、現(xiàn)在進(jìn)行時(shí)變?yōu)檫^去進(jìn)行時(shí)、一般將來時(shí)為過去將來時(shí)、現(xiàn)在完成時(shí)態(tài)變?yōu)檫^去完成時(shí)。如：

Didthetrainleave?Shedidn’tknow.→Shedidn’tknowif/whetherthetrainhadleft.Ⅲ.if和whether的區(qū)別二者在下列幾種情況下不能換用：1.賓語從句置于句首表示強(qiáng)調(diào)時(shí)，應(yīng)用whether，不用if。如：

Whetherthisistrueornot,Ican’tsay.

這是否對，我不能說。2.賓語從句與ornot直接連用時(shí)，應(yīng)用whether，不能用if。如：

Idon’tknowwhetherornothewillcometomorrow.

我不知道他明天是否來。3.與動詞不定式連用時(shí)，只能用whether。如：

Shecan’tdecidewhethertogotoAmerica.

她不能決定是否去美國。4.從句作介詞賓語時(shí)，只能用whether。如：

IworryaboutwhetherIhurtherfeeling.

我擔(dān)心是否傷了她的感情。5.賓語從句的謂語動詞是否定形式時(shí)，只能用if，不能用whether。如：

Tomwantstoknowifhewon’tcomeheretomorrow.

湯姆想知道他明天是否不來這兒。6.if意為“假如，如果”時(shí)，可以引導(dǎo)條件狀語從句，而whether沒有這個用法。如：

IfSimoncomesheretomorrow,I’llcallyou.

假如西蒙明天來這兒，我將打電話告訴你。1.Idon'tknowifMr.Wang____onafieldtrip.Ifhe___onafieldtriptomorrow,pleasecallme.A.goes;willgoB.willgo;goesC.willgo;willgoD.goes;goes2.SheaskedmeifIknew______.A.whosepenwasitB.whosepenitwasC.whosepenitisD.whosepenisitBB3.Theywonderediftheteacher______usEnglishthenextterm.A.wouldteachB.hadtaughtC.willteachD.taughtAChoosetherightanswers.5.Ihaven’tdecide____I’llgooutorstayathome.A.ifB.whenC.whyD.whether6.Iwanttoknow______helovesyou.A.thatB.whatC.ifD.whoDC4.Theboyasked______anynoisefromoutside.A.whetherhadIheardB.whetherIhadheardC.whetherhaveIheardD.whetherIhaveheardBAC

三、賓語從句的句型變化賓語從句的句型變化一般體現(xiàn)在主句的變化上。PleasetellmehowIcangothere.CouldyoupleasetellmehowIcangothere?Don’ttellmehowIcangothere.四、賓語從句的否定轉(zhuǎn)移：如果主句的謂語動詞是think,believe,guess,suppose等，而且主句的主語又是第一人稱時(shí)，它后面接的賓語從句的否定詞通常要前移到主句中，即否定主句中的動詞，而從句用肯定形式．即：主語為第一人稱，否定在主句，翻譯在從句。
