高三英语一轮复习 定语从句课件

定语从句关系副词的用法及定语从句用法的其他要点•一.当关系词在定语从句中做状语时，要用关系副词。其中when=表时间的介词（in/on/at/during等）+which;why=表原因的介词（如for)+which;where=(表地点的介词in/on/at/under等）+which.如；•IstillrememberthedaywhenIfirstcametoBeijing.(when=onwhich)•Canyoutellmetheofficewhereheworks?•(where=onwhich)•Doyouknowthereasonwhyheisabsent?•(why=forwhich)•二.where/when=介词+关系代词（which)有时为了表达清楚，还可以在关系副词where/when前加介词from/to等。•Chinaisthebirthplaceofkites,fromwhere•KiteflyingspreadstoJapan,Korea,Thailandand•India.•Lookoverthere.Somepeoplearestandingunderthebigtree,fromwhereweenjoythewholeview.•分析：where代表underthebigtree这个地方，如果用which就只能代表thebigtree,这句话的意思不是Enjoytheviewfromthebigtree而是fromunderthebigtree所以只能用from•Where•Sheclimbeduptothetopofthehill,fromwhereshecouldhaveagoodviewofthewholetown.•(fromwhere=fromonthetopofthehill)•Alicestoodinfrontofthewindow,fromwhereshecouldwatchherclassmatesplayingbasketball.•(fromwhere=frominfrontofthewindow)•Wewentuptotheroof,fromwherewehadagoodviewoftheprocession（游行队伍）•（fromwhere=fromonthetopoftheroof)•三.关系副词可用于非限制性定语从句中而•关系副词why不可以。•四.高考对关系副词where的考察•高考试题中队where的考察趋于复杂，从先行词为明显的“地点”转为“模糊化的地点”。•事实上，对于where这个词不能只理解为标地点。当先行词为situation/case/stage/point等，且先行词在定语从句中做状语时，也要用关系副词where引导。•Theyhavereachedthepointwheretheyhavetoseparatewitheachother.•Let’sthinkofasituationwherehisidiomcanbeused.•IhavereachedapointinmylifewhereIamsupposedtomakedecisionsofmyself.Thosesuccessfuldeafdancersthinkthatdancingisanactivitywheresightmattersmorethanhearing.四.关系代词和关系副词的比较关系代词和关系副词在定语从句中除了其连接主句和从句的作用外，他们换在定语从句中担当句子成分。关系代词在定语从句中担当主语，宾语，•定语、表语，而关系副词在定语从句中作状语。因此，在选择关系词时最主要的是分析定于才能根据中所缺的成分，如果从句中缺少主语，宾语，定语，表语就选关系代词，如果缺少状语就选关系副词。•比较下列句子•Doyoustillrememberthedaythat/which/不填wespentinQingdao?•DoyoustillrememberthedaywhenwespentthesummerholidayinQingdao?•题组训练•用that/which/when/where/why填空•1.Iwanttoknowthedate_____youwereborn.•2.Ihaveforgottenthedate______youtoldme•3.Doyouknowthereason______heisabsentwhenWhich/thatwhy•Today.•4.Thisisthefactory_____hisfatherworks.•5.Thisisthefactory______hisfatherbuilt.•五.定语从句用法的其他要点•1.定语从句中的谓语动词的单复数形式与先行词的单复数形式要保持一致。•（1）oneof+复数名词+关系代词+动词复数形式wherethat/which•TheGreatWallisoneoftheworle-famous•buildingsthatdrawlotsofvisitors.•TitanicisoneofthemostwonderfulmoviesthathavebeenproducedinHollywood.•(2)theonlyoneof+复数名词+关系代词+•动词单数形式•TianticistheonlyoneofthewonderfulmoviesthathasbeenproducedinHollywood.•Note:nottheonlyof…=oneof…•Tomisn’ttheonlyoneoftheboyswhopassedtheexam.=Tomisoneoftheboyswhopassedtheexam.•(3)当关系代词as与which引导非限制性定语从句，指代主句内容时，若as与which做主语，则从句谓语动词用单数形式•GreatchangeshavetakenplaceinChina,asisknowntoall.•Hehaspassedthecollegeentranceexamination,whichmakeshisparentsquitehappy.•(4)其他情况•I，whoamyourteacher,willtrymybesttohelpyou.•Toownacomputerinfamilies,whichwethoughtwasimpossibletwentyyearsago,now•Becomestrue.题组训练用所给动词的适当形式填空1.Heistheonlyoneofthestudentswho______(have)passedtheexam.2.Heisnottheonlyoneofthestudentswho________(have）passedtheexam.3.I,who_______(be)verybusy,can’thelpthematthemoment.4.As_______(be)knowntoeverybody,Taiwanhashaveamis•isapartofChinawemustunifyit.•5.theidea,whichIthink________(be)•Reasonable,wasbroughtupbyProfessorLi•Yesterday.•6.Istillremembertheteachersandtheschool•that_______(be)talkedofyesterday.•2.注意way/time后接定语从句的情况iswere•（1）当先行词way当”方式、方法“时引导定语从句的先行词有下列三种情况•Whatsurprisedmewasnotwhathesaidbut•thewayinwhich/that/不填hesaidit.•注意下面两个句子中关系词的不同•Thewaythat/which/不填heexplainedtous•wasquitesimple.•Thewaythat/inwhich/不填heexplainedthesentencetouswasnotdifficulttounderstand.•(2)先行词如果是time,若time做次数讲时•应用关系代词that引导定语从句，that可以省略。若time做“一段时间，时代”讲且做状语时，应用关系副词when或介词at/•during+which引导定语从句•Thisisthesecondtime(that)thepresident•Hasvisitedthecountry.•Icouldhardlyrememberhowmanytimes•(that)Ihavefailed.•Thisisatatimewhen/duringwhichtherewerenoradios,notelephoneornotvsets.•题组训练用适当的关系代词，关系副词或介词+关系代词填空•1.Idon’tliketheway____________helaughs•ather.•2.Thisisthesecondtime____________Ihavebeenhere.That/which/不填that/不填•3.Canyoustillrememberthetime_________•wespenttogetherinourchildhood?•4.Thefirsttime_____________hesawher•,hefellinlovewithher.that/which/不填that/不填
