whom和whose，关系副词包括where,when,why等。先行词关系词定语从句定语从句三要素：先行词，关系词，定语从句Thereareafewstudentswhokeepcomingtoclasslate.

马先行词马车夫关系词马车定语从句when引导的定语从句修饰表示时间(如time,day,year,occasion,moment....)的先行词,在定语从句中作时间状语,相当于“介词+关系代词(which)”。I’llneverforgettheday

peopleliketraveling.表示原因的先行词在定语从句作原因状语关系副词why引导的定语从句表示原因(先行词一般是reason),在定语从句中作原因状语，相当于“forwhich”。=forwhich(=forthereasons)关系副词whyIdon’tknowthereason________________________________________我不知道她为什么如此迷恋鹿晗。why/forwhichsheissocrazyaboutLuHan.Exercisewhere引导的定语从句修饰表示地点(如place,room,house,area,point,situation,case…)的先行词，在定语从句中作地点状语，相当于“介词+关系代词(which)”。关系副词whereThisisthehousewhereIlivedtwoyearsago.表示地点的先行词在定语从句作地点状语=inwhich(=inthehouse)Thatistheplace_____________theymetforthefirsttime.那就是他们第一次见面的地方。where/inwhich

where引导定语从句时，先行词为表示地点的名词，关系词在从句中作地点状语。EmperorQinshihuangunitedthesevenmajorstatesintooneunifiedcountry.InthatcountrytheChinesewritingsystembegantodevelopinonedirection.where还可用在表示抽象意义的地点名词后，如situation,stage,point,case,position,condition,activity,scene,occasion等,意思是“到了某种地步，在某种境况中”。Theaccidenthasreachedtothepointwhereboththeirparentsaretobecalledin.关系副词Refertoexampleswhere=in/atwhichTheschool

Exercise很多情况下关系副词用“介词＋which”来代替时,其介词由先行词或定语从句中谓语动词的形式来决定。①Ishallneverforgetthoseyears

whenIlivedwithher.=Ishallneverforgetthoseyears____________Ilivedwithher.②Thisisthehouse

whereIlivedtwoyearsago.=Thisisthehouse__________Ilivedtwoyearsago.③A:Theradiosaysthatitwillraintomorrow.

B:Thisisthereasonwhyweputoffthematch.=Thisisthereason________weputoffthematch.duringwhichinwhichforwhich3.“介词+关系代词”之介词的选择(1)与从句中谓语动词的搭配相关Thisisthebook_____whichIspent10yuan.Thisisthebook_____whichIpaid10yuan.(2)与先行词的搭配相关I'llneverforgettheday_____whichIwonthefirstprizeintheEnglishcontest.(3)与所表达的意义相关Thecolorlessgas_______whichwecannotliveiscalledoxygen.onforonwithout关系代词前介词选择三原则一先二动三意义即根据先行词与介词的搭配关系选择根据谓语动词与介词的搭配关系选择即根据定语从句的意义来确定介词注意：1.time用做先行词注意2.

way

作为先行词时，且在定语从句中

充当状语时，其定语从句关系词可为：

inwhich,that,〵

Thisisagoodwayinwhichtheproblemcanbesolved.=Thisisagoodwaythattheproblemcanbesolved.=Thisisagoodwaytheproblemcanbesolved.注意3.“模糊地点”的先行词后跟where引导的定语从句，先行词可为point,situation,case,conditions,position,stage,scene,spot,activity,family,job另，常见的“模糊时间”的先行词有occasion,stay,interval等，用when来引导定语从句。

(注意：此时关系词要在定语从句中充当状语）TheInternet,______
