定语从句限制性定语从句与非限制定语从句区别限制性定语从句（与主句无逗号分开）对先行词起修饰限制作用，而非限制定语从句（与主句有逗号分开）对先行词起补充说明作用，相当于并列句、状语从句等。注意：关系代词that和which中只有which能引导非限制定语从句，但除了which其他关系代词如who/whose/whom和关系副词如where/what/why等也能引导非限制定语从句。Eg.Iwantthisman,whocanspeakEnglish.Eg.Chinaisthebirthplaceofkites,fromwherethekitespreadtoJapan,Korea,andIndia.限制性定语定语从句中必须用关系代词that的情况：当先行词是不定代词all,something,everything,anything,nothing,none,theone,every,any,no等Eg.Doyouhaveanythingthatyouwanttosaytome？当先行词前面有theonly,thevery,thelast,thesame,the+序数词，the+形容词最高级Eg.ThisistheverypersonthatI’mwaitingfor.Eg.ThisisthemostinterestingfilmthatI’veeverseen.Eg.WhatisthefirstAmericanfilmthatyouhaveseen?先行词既有人又有物时Eg.Doyouknowthethingsandpersonsthattheyaretalkingabout?介词+whichEg.Thepoormanhasnohousetolivein.改成定语从句:Thepoormanhasnohouseinwhichhecanlive.whoseeg.Thisisthehouse,whosewindowbrokelastnight.=Thisisthehouse,thewindowofwhichbrokelastnight.关系代词as引导的定语从句as可以引导限制性和非限制性定语从句，引导限制性定语从句常用以下句式：such+名词+as…像…一样；像…之类的thesame+名词+as…和….同样的Eg.Heisnotthesamemanashewas.Eg.Wehavefoundsuchmaterialsasareusedintheirfactory.高考对关系副词where的考察对于where这个词，考生不能只理解为表示地点，事实上当先行词是表示某人/物的situation,或某事发展的stage,或表达事物的某个方面时都可以用where。Eg.Theaccidenthadreachedtoapointwhereboththeirparentsaretobecalledin.事情发展到如此地步，不得不请双方家长来一趟了。Eg.Hewasdrivingsofastastogethimselfintoadangeroussituationwhereheislikelytolosethecontroloverhiscar.way和time后接定语从句的情况1．当先行词是way，意为“方式、方法”时，引导定语从句的关系代词有下列三种形式。如:Whatsurprisedmewasnotwhathesaidbutthewayinwhichhesaidit.that不填注意下面两个句子中关系词的不同：Thewaythatheexplainedtouswasquitesimple.(theway作explain的宾语)which他向我们解释的那种方法很简单。不填thatThewayinwhichheexplainedthesentencetouswasnotdifficulttounderstand.不填他向我们解释句子的那种方法不难理解。(theway作explain的方式状语)2．Time作次数讲时，应用关系代词that引导，that可以省略；作一段时间讲用时间副词when或at/during+which引导。Eg.Thisisthefirsttime(that)IhavecometoFenghuiMiddleSchool.Eg.Canyoustillrememberthetimewhenwespenttogetherinourchildhood.定语从句用法其他要点Oneof+复数名词+关系代词+复数动词Eg.TheGreatWallisoneoftheworld-famousbuildingsthatdrawlots
