whom和whose，關(guān)系副詞包括where,when,why等。先行詞關(guān)系詞定語從句定語從句三要素：先行詞，關(guān)系詞，定語從句Thereareafewstudentswhokeepcomingtoclasslate.

where引導(dǎo)定語從句時(shí)，先行詞為表示地點(diǎn)的名詞，關(guān)系詞在從句中作地點(diǎn)狀語。EmperorQinshihuangunitedthesevenmajorstatesintooneunifiedcountry.InthatcountrytheChinesewritingsystembegantodevelopinonedirection.where還可用在表示抽象意義的地點(diǎn)名詞后，如situation,stage,point,case,position,condition,activity,scene,occasion等,意思是“到了某種地步，在某種境況中”。Theaccidenthasreachedtothepointwhereboththeirparentsaretobecalledin.關(guān)系副詞Refertoexampleswhere=in/atwhichTheschool

Exercise很多情況下關(guān)系副詞用“介詞＋which”來代替時(shí),其介詞由先行詞或定語從句中謂語動(dòng)詞的形式來決定。①Ishallneverforgetthoseyears

whenIlivedwithher.=Ishallneverforgetthoseyears____________Ilivedwithher.②Thisisthehouse

whereIlivedtwoyearsago.=Thisisthehouse__________Ilivedtwoyearsago.③A:Theradiosaysthatitwillraintomorrow.

B:Thisisthereasonwhyweputoffthematch.=Thisisthereason________weputoffthematch.duringwhichinwhichforwhich3.“介詞+關(guān)系代詞”之介詞的選擇(1)與從句中謂語動(dòng)詞的搭配相關(guān)Thisisthebook_____whichIspent10yuan.Thisisthebook_____whichIpaid10yuan.(2)與先行詞的搭配相關(guān)I'llneverforgettheday_____whichIwonthefirstprizeintheEnglishcontest.(3)與所表達(dá)的意義相關(guān)Thecolorlessgas_______whichwecannotliveiscalledoxygen.onforonwithout關(guān)系代詞前介詞選擇三原則一先二動(dòng)三意義即根據(jù)先行詞與介詞的搭配關(guān)系選擇根據(jù)謂語動(dòng)詞與介詞的搭配關(guān)系選擇即根據(jù)定語從句的意義來確定介詞注意：1.time用做先行詞注意2.

way

作為先行詞時(shí)，且在定語從句中

充當(dāng)狀語時(shí)，其定語從句關(guān)系詞可為：

inwhich,that,?

Thisisagoodwayinwhichtheproblemcanbesolved.=Thisisagoodwaythattheproblemcanbesolved.=Thisisagoodwaytheproblemcanbesolved.注意3.“模糊地點(diǎn)”的先行詞后跟where引導(dǎo)的定語從句，先行詞可為point,situation,case,conditions,position,stage,scene,spot,activity,family,job另，常見的“模糊時(shí)間”的先行詞有occasion,stay,interval等，用when來引導(dǎo)定語從句。

(注意：此時(shí)關(guān)系詞要在定語從句中充當(dāng)狀語）TheInternet,______
