定语从句解题核心要点：
1. 先行词判断法：先确定先行词是人还是物，再根据关系词在从句中充当的
成分选择合适的关系词。
2. 关系代词与副词的区别：关系代词（who, whom, which, that, whose）在
从句中作主语、宾语或定语；关系副词（when, where, why）在从句中作状
语。
3. 限制性 vs 非限制性：非限制性定语从句用逗号隔开，不可用that 引导，
常用which 指代前面整句内容。
4. 介词+关系代词：介词的选择取决于先行词与介词的搭配或从句中动词的
固定搭配。
5. 特殊结构：掌握as 引导的非限制性定语从句（as is known to all, as is
often the case），以及such...as, the same...as 结构。
