九年级定语从句讲解

定语从句
1. 定义：
在复合句中作定语，修饰主句中某一名词或代词的从 句，叫做定语从句。被定语从句所
修饰的词叫做先行词，引导定语从句的是关系代词(that, which, who, whom, whose)和关
系副词（when, where, why）。
2. thatwhichwho引导的定语从句：
1）that在从句中作主 语或宾语，可指物或指人；并且作宾语时可省略；介词后一般不
用that；
2）which在从句中作主语或宾语，指物；并且作宾语时可省略；
3）whowhom在从句中分别作主语和宾语，指人；
3. 注意：从句的谓语和先行词的单复数保持一致。
4. 关系代词的特殊用法：
1）如果先行 词是allanythingeverythingsomethingnothingmuchlittlen one等不定代词，
或被不定代词修饰时，关系代词一般用that。
2）当先行词被nothe onlythe very等限定词所修饰时，定语从句常用that引导。
3）先行词被序数词或形容词最高级修饰时，定语从句只能用that引导。
4）先行词为d aymomenttimeway等词语时，定语从句要以that引导，不用which。
5）当先 行词由人和物（或动物）两个并列的名词共同组成时，定语从句要以that引导，
不用which。
6）主句是以who或which开头的特殊疑问句，疑问代词who或which又作先行词时，为避免重复whowhich等，定语从句只能用that引导。但是先行词是人称代词和指示代
词 时，常用who来引导定语从句。
