1、定语从句中关系代词的确定：一、关系代词选定要诀：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；wh
2、ose 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/最高级，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。请在横线上添上恰当的关系词：1.
