初中英语语法定语从句教案东宁市绥阳镇中学周芳宇教学目标：1.学生能掌握关系代词和关系副词的正确使用。           2.学生能正确理解整个句子的意思  教学重难点：定语从句中引导词（who, whom, whose，that , which，when，where, why）的正确使用 教学过程： 图片导入：   ThisisALi.ALiisalovelyboy. ThisisALiwhoisalovelyboy.一.定义：在复合句中，用来修饰某一名词或代词的从句叫做定语从句。被定语从句修饰的名词、代词叫先行词。定语从句放在先行词之后。ALi  isaboywhohasmagicpower.      先行词（人）   ↘引导词（who指代）ALi  二.引导词：关系代词：who, whom, whose，that , which（表人、表物，作主语，宾语）           关系副词：when，where, why, （表时间、地点、原因，作状语）    三．归纳总结：当先行词是人：who,whom,that,whose当先行词是物：which,that,whose关系副词when, where,why的用法：  1.(先行词是时间名词时，关系副词用when) Iwillneverforgettheday,whenIjoinedtheParty.—Iwillneverforgettheday,onwhichIjoinedtheParty. 2.先行词表示地点名词时，引导词用where,在句中作状语。  ThisistheschoolwhereIstudiedafewyearsago.—ThisistheschoolinwhichIstudiedafewyearsago.3.先行词是the reason时，关系副词用why,也可省略。 Doyouknowthereasonwhyheisnotherenow?—Doyouknowthereasonforwhichheisnotherenow?四．分类：定语从句分为限制性定语从句和非限制性定语从句。一般说来，限制性定语从句是整个句子不可缺少的部分，如果省略会影响全句的主要思想，这种定语从句前面一般不用逗号；而非限制性定语从句则只是主句的一种补充说明，即即使去掉，也不会影响全句的主要思想，这种定语从句前通常有逗号隔开。如：Thisisthebookthatyouwant.这就是你要的那本书。 句中的youwant为限制性定语从句，如果去掉，意思就不清楚。Heboughtmeabook,whichwasveryuseful.他给我买了一本书，非常有用。句中的whichwasveryuseful为非限制性定语从句，如果去掉，句子意思仍是清楚的。五．初高中衔接关系代词在定语从句中的成份1.ThemancametoourschoolisMr.Wang.2.ThegirlImetisLucy.3.Ilikethebookyouboughtyesterday.4.Themanisspeakingatthemeetingisaworker.5.Thewomantheywantedtovisitisateacher.6.ThisisatruckismadeinChina.7.Ilikethebookyouboughtyesterday.六．难点精析1whose用法既可以修饰人又可以修饰物作定语1.AchildwhoseparentsaredeadiscalledTom.whose+n.=the+n.+ofwhom=ofwhom+the+n.Achildtheparentsofwhom(ofwhomtheparents)aredeadiscalledTom.2.Thehousewhosewindowfacessouthismyhome.whose+n.=the+n.+ofwhich=ofwhich+the+n.精析精练【2016·】Ilivenextdoortoacouple________childrenoftenmakealotofnoise.【2014·】Acompany______profits(利润)fromhomemarketsaredeclining(下降)mayseekopportunitiesabroad.难点精析2.先行词表物时，用that或which that与which的区别： that和which都可表物，一般可互换，但下列情况只用that⑴ 先行词为：everything, nothing, something, anything, 等不定代词时引导词用that   ⑵ 先行词被all, every, no, some, any, little, much等修饰时⑶先行词被序数词和最高级修饰时 4. This is the only book that belongs to him. ⑷先行词被the only, the very, the same, the best, the last等修饰时⑸先行词既有人也有物(6).当主句 以who或which开头时，为避免重复引导词用that 难点精析3.只用which，不用that的情况①在非限制性定语从句中，只用which，不用that②当关系词前有介词时③当先行词本身是that时④关系词后有插入语时巩固练习： 1.Ihaveafriend________likeslisteningtoclassicalmusic. 2.YesterdayEmilywaswearingthenewdress_______Igaveher. 3.Theman______legbrokeinamatchusedtobeafootballplayer.4.Myparentsliveinahouse_______ismorethan100yearsold.5.Theboywith_______Johnspokeismybrother.6.Kevinisreadingabook_________istoodifficultforhim.7.Isthereanything________youwanttobuyinthetown.8.All______wecandoistostudyhard.9.Thefirstone_____standsupisalittleboy.七总结:引导定语从句的关系代词Homework:Finishtherestoftheexercises.
