初中英语定语从句专题复习课件

,定语从句的概念,在复合句中，修饰某一名词或代词的从句叫定语从句。被修饰的名词或代词叫先行词，定语从句一般放在先行词的后面。,引导定语从句的关系词有关系代词和关系副词，常见的关系代词包括that，which，who（宾格whom，所有格whose）等，关系副词包括where，when，why等。关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。,引导词,Exercise1:用关系代词填空,Theboy_isplayingping-pongismyclassmate.Thee-mail_Ireceivedyesterdaywasfrommysister.Ihatepeople_talkmuchbutdolittle.Thecar_myfatherboughtlastmonthisverybeautiful.,who/that,which/that,who/that,which/that,5.Theman_hairiswhiteishisgrandfather.6.Isthereastudent_fatherisabusinessman?7.Thisisthehousein_wehavelivedfor10years.8.Iveneverheardofthepeopleandthings_youtalkedaboutjustnow.,whose,whose,which,that,当先行词同时指人和物时，关系代词只能用that.,Exercise2.,Myfatherandhisteachertalkedalotaboutthepersonsandthings_theycouldntremember.Sayall_youknow.Isthereanything_Icandoforyou?,that,that,that,当先行词是all,much,any,many,anything,something,nothing,everything,theone,little,none,theonly，thevery，thesame，thelast，little，few等不定代词时，关系代词只能用that.,4.Thisisthefirstplay_IhaveseensinceIcamehere.5.Thisisthebestnovel_Ihaveread.,that,that,当先行词被序数词，最高级等词修饰时，关系代词只能用that.,6.Whoisthegirl_isstandingunderthetree?7.Whichisthemachine_weusedlastSunday.,当主句是who或which引导的特殊疑问句，而中心词指人或物时，关系代词只能用that.,that,that,8.Thisisthehousewelivedlastyear.,inwhich,9.PleasetellmeyouborrowedtheEnglishnovel.,fromwhom,当定语从句中含有介词，介词放在句末时，who，that，which可省略，但介词在关系代词前时，只能用“介词+which/whom”结构。,Thisisthepersonyouarelookingfor.,whom,含有介词的固定动词词组中，介词不可前置，只能放在原来的位置上。,关系词只能用which，而不用that的情况：,a.先行词为that，those时，用which，而不用that.例如：Whatsthatwhichisunderthedesk？在桌子底下的那些东西是什么？b.关系代词前有介词时，一般用which，而不用that.例如：Thisistheroominwhichhelives.这是他居住的房间。c.引导非限制性定语从句，用which，而不用that.例如：Tomcameback，whichmadeushappy.汤姆回来了，这使我们很高兴。,关系副词的用法,Thiswasthetimehearrived.,when,Thisisplaceheworks.,where,Nobodyknowsthereasonheisoftenlateforschool.,why,when指时间,其先行词表示时间，在句中作时间状语.where指地点,其先行词表示地点，在句中作地点状语。why指原因,其先行词是原因，起原因状语作用。,Aguessingcompetition,Itsaninventionwhichisusedforkeepingofftherain.,飘,ItsabookthatwaswrittenbyMargaretMitchell.,Gonewiththewind,ItstheWallthatwasbuiltbyChinesepeople.,Itsananimalthat/which.,Matchthetwosentences1.Imreadingabook.ThebookisaboutBillGates._2.Heisateacher.TheteacherteachesusChinese._3.Idontliketheman.Heissmoking._4.Whereisthepicture?Youboughtitlastweek._,Imreadingabookthat/whichisaboutBillGates.,Heisateacherwho/thatteachesusChinese.,Idontlikethemanwhoissmoking.,Whereisthepicturethatyouboughtlastweek?,1.Theperson_youshouldwritetoisMrBall.2.Theteacherfrom_IlearntmostwasMrsZhu.3.Therunner_youareaskingaboutisoverthere.4.Thegirl_youarelookingforisintheclassroom.5.Themeeting_weshalltakepartinwillbeheldinahotel.6.Thefactory_Iworkedinforovertwoyearshasbeenclosed.7.Theairport_is30kilometresawayistheonlyoneinthecity8.Theperson_wontheracewasawomanfromSichuan.,who,whom,who/whom,who/whom,that,which,that,who,Thehousethattheybuiltitin1987stayedupintheearthquake.Iwillneverforgetthepoorboywhohavenoarms.Wehavedoneeverythingwhichcanbedone.HeistheonlymanwhoIknowinthecity.TheparkwheretheoldpeopleusuallygotoiscalledZhongshanpark.Jimaskedthatwhowon.Look!T
