定语从句的讲与练定语从句1.定语从句的结构及理解2.定语从句的关系词的使用3.定语从句的简化表达知识总结归纳（一）定语从句的结构：在复合句中，修饰某个名词或代词的句子（做这个名词或代词的定语）叫定语从句，定语从句一般放在被修饰的名词或代词后面，被修饰的名词或代词叫做定语从句的先行词，它与定语从句之间要有一个词连接，这个词指代先行词的内容叫做关系词（关系代词或关系副词：that,which,who,whose,when,where,why）。先行词在定语从句中充当主语，宾语，时间，地点，原因状语。结构：先行词+关系词+定语从句。1.Thereshesawawallofwaterthatwasquicklyadvancingtowardsher.2.InJapan,someonewhoseesanotherpersonmakingthegesturewillthinkitmeansmoney.3.Athemeparkisacollectionofrides,exhibitionsorotherattractionsthatarebasedonacommontheme.4.TheparkhasaconservationcenterthathelpsprotectmarineanimalsandtheirhabitatsintheriversandcoastalwatersofAsia.5.Visitorscangoonexcitingrideswheretheycanfeelwhatitisliketodothethingstheyhaveseentheirheroesdointhemovie.6.OprahWinfreyisablackwomanwhoserisetofameisaninspiringstory.（二）定语从句分为限定性定语从句和非限定性定语从句：限定性定语从句：从句对先行词进行必要的描述或说明，缺少它，则句义显得不完整，从句与先行词紧密相连。非限定性定语从句：对先行词进行补充说明，解释，它与先行词之间有逗号隔开。1.Beforeshecouldmove,sheheardaloudnoise,whichgrewtoaterribleroar.2.Treeaftertreewentdown,cutdownbythewater,whichmusthavebeenthreemetersdeep.3.Flora,whosebeautifulhairanddresswereallcoldandwet,startedcrying.4.Theirtalkincludesrhythmandrhymingwordsaswellastonguetwisters,whichoftenmaketheaudienceapplaud.1/6（三）关系词前面可以根据定语从句的内容加上一些介词，这些关系词在介词后面常用which或whom.1.TherewasamanwithwhomIwouldhavetoworktogetherandfinallythemanagerofthecompany.2.Manypeoplewhosawthefilmwereafraidtoswimintheseawhentheyrememberedthescenesinwhichpeoplewereeatenbytheshark.知识重点与难点（一）当先行词有最高级，序数词修饰，是不定代词，或是all,no,only等形式时，关系代词一般用that，而不能用which。1.TheTitanicwasthelargestshipthathadeverbeenbuiltatthattime.2.Thereisonethingthatkeepsworryingme.（二）当先行词是表示时间，地点，原因的词时，关系词用when,where,why还有which,that1.I’mverygladtoreturntomyhometownwhereIhadlivedfor10years.2.ThisismyhometownwhichIusedtotalkabouttoyou.3.IthinkIcanunderstandthereasonwhyhedidn’ttellthetruthtome.4.Noonebelievesthereasonthathegaveusabouthisabsenceatthemeeting.（三）定语从句的简化表达：1.ThemanwhoissittingontheplatformisaprofessorfromWuhanUniversity.2.Theletterthatwasmailedlastnightwillreachhimtomorrow.3.Thequestionthatisbeingdiscussedisveryimportant.4.Youarewelcometoapartytobegiveninourclassat7:45.说明：以上的定语从句部分可以用更加简单的非谓语形式表达出来：1.ThemansittingontheplatformisaprofessorfromWuhanUniversity.2.Thelettermailedlastnightwillreachhimtomorrow.3.Thequestionbeingdiscussedisveryimportant.4.Youarewelcometoapartytobegiveninourclassat7:45.说明：修饰一个名词除了后面用定语从句以外，还可以用非谓语动词形式：doing短语，done短语，beingdone短语，tobedone短语修饰。其结构和意思如下：1.被修饰名词+doing短语：正在做….的人/正在发生的事。2.被修饰名词+done短语：被…..的人/事3.被修饰名词+beingdone短语：正在被…..的人/事4.被修饰名词+tobedone短语：将要被…..的人/事2/6（1）Doyouknowthemantalkingtomysister?（2）The“crazy”gesture,movingtheindexfingerinacircleinfrontoftheear,means“youhaveaphonecall”inBrazil.（3）Didyouseethatcarbeingrepaired?（4）Inacame...
