定语从句中关系代词的确定

　　定从要学好，删繁就简系⾸要，明确先⾏词，然后定关系词调； 　　指⼈主格⽤who，宾格whom好，事物⽤which，主/宾都可靠； 　　⽤that引定从，⼈/物均需要，⾮限制性定从句，切勿⽤that导；

　　关系词作宾语，常将其省略掉，若介词+关系词，关系词切勿抛，⽆论⼈/事物，who/that均不导，指⼈必whom，事物which邀；　　

　　as引定从，（部分）主句内容包，常含“正如”意，位置任意挑； 　　which如此⽤，⽤时思量好，有时含“消极”味，主句之后到；

　　such/ the same + as，固定搭配好，特殊⽤法务牢记，勿⽤乱了套； 　　whose作定语，⼈/物它全包，n. + of + whom/which，可与其对调。 　　⼆、只⽤that作关系代词的⼏种情况

　　先⾏（词）本⾝系数词，不定代词指事物， 　　⼈与事物共先⾏，There be中指物词作主语， 　　关系词定从中作表语，问句避免疑问词重复， 　　另有序数词/级，every/ the very/ the only， 　　以及不定代词若⼲个，名词前把事物来修饰， 　　以上情况请记清，只能使⽤that引导定从句。 　　[巩固练习]
