高中定语从句

定语从句
【知识简介】
名词或代词由一个从句来修饰，该从句即定语从句。定语从句一般后置，但as引导的修饰全句的定语从句可以前置。
引导定语从句的词有关系代词that, which, who, whom, whose, as等以及关系副词when, where, why等。关系代词或关系副词放在被修饰的名词或代词（又叫做先行词）和定语从句之间起联系作用，同时又作定语从句中的一个成份。
【要点难点】
1) that和which的用法区别
只用that的情况：
① 先行词由最高级修饰时，如the best work that I can do。
② 先行词由序数词修饰时，如the second book that I bought。
③ 先行词由the last, the only, the same, the very等修饰时。
④ 先行词是不定代词all, anything, everything, little, much, nobody, nothing等时，如anything that he does; all that I can do now等。
⑤ 先行词有any, no, all等限定词时，如all the words that I’ve learned。
⑥ 先行词为词组，该词组既含人又含物时，如the city and the people that I visited。
只用which的情况：
① 在非限定性定语从句中（定语从句前有逗号）。
② 介词后。
请看that和which的使用例句：

2) 关系代词（that, which, who, whom等）和关系副词（when, where等）的用法区别
① 关系代词在定语从句作主语、宾语或表语，而关系副词在定语
