定語從句中關(guān)系代詞的確定

　　定從要學(xué)好，刪繁就簡系首要，明確先行詞，然后定關(guān)系詞調(diào)；

　　指人主格用who，賓格whom好，事物用which，主/賓都可靠；

　　用that引定從，人/物均需要，非限制性定從句，切勿用that導(dǎo)；

　　關(guān)系詞作賓語，常將其省略掉，若介詞+關(guān)系詞，關(guān)系詞切勿拋，無論人/事物，who/that均不導(dǎo)，指人必whom，事物which邀；　　

   as引定從，（部分）主句內(nèi)容包，常含“正如”意，位置任意挑；

　　which如此用，用時思量好，有時含“消極”味，主句之后到；

　　such/ the same + as，固定搭配好，特殊用法務(wù)牢記，勿用亂了套；

　　whose作定語，人/物它全包，n. + of + whom/which，可與其對調(diào)。

　　二、只用that作關(guān)系代詞的幾種情況

　　先行（詞）本身系數(shù)詞，不定代詞指事物，

　　人與事物共先行，There be中指物詞作主語，

　　關(guān)系詞定從中作表語，問句避免疑問詞重復(fù)，

　　另有序數(shù)詞/最高級，every/ the very/ the only，

　　以及不定代詞若干個，名詞前把事物來修飾，

　　以上情況請記清，只能使用that引導(dǎo)定從句。
