限制性定语从句1. 定义：在复合句中，修饰名词或代词的从句叫作定语从句。它所修饰的名词或代词叫作先行词；引导定语从句的词叫作关系词。2. 位置：位于名词或代词后。3. 作用：限制性定语从句与先行词之间的关系非常密切，从句说明先行词的性质、身份、特征等状况，使句子的表意更加完整。4. 关系词（1）作用：① 连接主句和从句；② 指代先行词；③ 在从句中充当成分。
限制性定语从句（2）分类：关系代词：that、which、wh（whm）、whse
限制性定语从句注意：that、which、wh（whm）在从句中作宾语时，特别是在口语或非正式的书面表达中，常常省略。关系代词whse引导的定语从句：关系代词whse引导的定语从句先行词既可以是人，也可以是物。whse在从句中作定语。She is the girl whse brther is studying abrad.（先行词是人）The rm whse windw faces suth is mine.（先行词是物）I talked with the man whse huse was destryed in the fld.（先行词是人）He has written a bk whse name I’ve frgtten.（先行词是物）
限制性定语从句关系代词的选择：① 宜用that不用which的情况：先行词是all，much，anything等不定代词时；先行词为序数词/形容词最高级或被这两者修饰时；先行词被all，n，few，any，little，sme，much，the last，the nly，very等修饰时；先行词既有人又有物时；主语是以wh或which开头的特殊疑问句时；先行词在主句中作表语，且关系代词本身在定语从句中也作表语时；主句以here，there开头且先行词指物时。
限制性定语从句关系代词的选择：② 宜用which不用that的情况：先行词为that时；关系代词后面有插入语时；在限制性定语从句中，如果有两个定语从句，其中前面一个关系代词是that，那么后一个的关系代词宜用which。③ 宜用wh不用that的情况：先行词为指人的不定代词，或先行词为thse或被其修饰且指人时；一个句子中含有两个定语从句，且先行词都为人时，其中一个定语从句的关系代词是that，另一个一般用wh。
