陕西省澄城县寺前中学高三英语专题复习定语从句教案教学内容：定语从句的基本用法教学重难点：定语从句中关系词的选择教学过程：一、考点聚焦1、功能：相当于形容词，修饰名词或代词，在句中作定语2、位置：定语从句置于被修饰词之后Thosewhoarewillingtoattendtheparty,signhereplease.3、先行词：被定语从句修饰的词称为先行词1）先行词一般是名词和不定代词，如:some-,any-,every-和no与-boy,-thing的合成词；或all、none、any、some、that、those等代词。数词也可以作先行词，人称代词也同样可作先行词。2）先行词与关系词是等量关系。必须注意两点：①先行词在从句中作主语时，从句谓语动词的数由先行词而定。Thisistheplacewhichisworthvisiting.②关系词在从句句子中充当了成分，其意思就是先行词的意义，所以在从句中不能重复其意。Therearemanyplaceswecanvisit（them）inChina.4、关系词：引导定语从句的都称关系词关系代词：who,whom,which,that,whose,as。关系副词：when,where,why。that偶尔也作关系副词。5、确定关系词的步骤（1）先找关系词，看先行词指的是什么。（2）看关系词在从句中所充当的成分。6、在定语从句中，当先行词指物时，下列情况的关系词宜用that而不用which（1）先行词被①形容词最高级②序数词③数词几种词修饰或被④only、any、few、little、no、all、oneof等修饰时。（2）先行词为all、much、little、none、few、one、something、anything等不定代词时。（3）先行词中既有人又有物时。Hewaslookingpleasantlyattechildrenandparcelsthatfilledhisbus.（4）先行词在主句中作表语关系词在从句中作表语时。Thevillageisnolongertheonethatwas5yearsago.（5）当主句中含有疑问词which时。Whicharethebooksthatyouboughtforme?7、宜用which而不用that的情况（1）在非限制性定语从句中（2）在关系词前有介词时（3）当先行词本身是that时（4）当关系词离先行词较远时8、关系词who与that指人时，也有不同情况分别用不同的关系词（1）当主句是therebe句型时，关系词用who。（2）先行词是为anyone、those、someone、everyone、one等词时，关系词用who。（3）当主句是who作疑问词时，关系词用that。Whoisthatgirlthatisstandingbythewindow?（4）whom在从句中只作宾语，可被who取代。9、whose作关系词既指人又指物，在从句中作定语。如：DoyouknowMr.Smithwhosestoryisverymoving?Thereisaroom,whosewindowfacestheriver.Thereisaroom,thewindowofwhichfacestheriver.10、关系代词as,在从句中作主语、宾语和表语。（1）先行词被such和thesame修饰，或句型asmany（much）中，从句都用as引导。Suchbooksasyouboughtareuseful.Theschoolisjustthesameasitwas10yearsage.注意：区别①such…that…引导的结果状语从句。Theyaresuchlovelychildrenthatwelovethemmuch.②thesame…that…引导定语从句。Iwanttousethesametoolthatyouusedjustnow.（2）无先行词的定语从句用as和which引导。区别：①意义上：as含有“这点正如……一样”。②位置上：as从句可置句首，也可在另处。Hedidn’tpasstheexam,aswehadexpected.Thereislotsofairinloosesnow,whichcankeepthecoldout.Asisknown,theearthisround,notflat.基础过关：用合适的关系词完成句子。①Theman/washereyesterdayisapainter.②Theman///IsawiscalledSmith.③Achildparentsaredeadiscalledanorphan.④I'dlikearoomwindowlooksoutoverthesea.⑤Aletter/iswritteninpencilishardtoread.⑥Theletter//Ireceivedfromhimyesterdayisveryimportant.⑦Thatistheboy///youarelookingfor.⑧Doyouknowthereasonhewaslateforthemeeting.⑨ThisistheschoolIusedtostudy.⑩Istillrememberthedaywemetforthefirsttime.提高巩固1.Isthisthereason______heexplainedatthemeetingforhiscarelessnessinhiswork?A.thatB.whatC.howD.why2.Isthisthereason______hewassocarelessinhiswork?A.thatB.whatC.howD.why3.Thereason______hedidn'tcomewas______hewasill.A.why;thatB.that;whyC.forthat;thatD.forwhich;what4.Helivesina...
