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;

　　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/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。
