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

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

whenIlivedwithher.=Ishallneverforgetthoseyears____________Ilivedwithher.②Thisisthehouse

whereIlivedtwoyearsago.=Thisisthehouse__________Ilivedtwoyearsago.③A:Theradiosaysthatitwillraintomorrow.

way

作為先行詞時(shí)，且在定語(yǔ)從句中

充當(dāng)狀語(yǔ)時(shí)，其定語(yǔ)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(yǔ)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(lái)引導(dǎo)定語(yǔ)從句。
