5.先行词是表示时间的名词（year, month, day, night…），而关系词代替先行词在定语从句中充当时间状 语，一般用when引导定语从句。也可以用介词＋which的 结构。值得注意的是which前介词的选择是根据先行词与 介词的搭配关系而定。

• 定语从句一般都紧跟在它所修饰名词后面， 所以如果在名词或代词后面出现一个从句， 根据它与前面名词或代词的逻辑关系来判 断是否是定语从句。 被定语从句所修饰的名词或代词叫做 “先行词”。引导定语从句的词叫“关系 词”。关系词有两个作用：
• 一、引导定语从句。 二、代替先行词在其引导的定语从句 中充当一定的句子成分。 理解和牢记这两条概念，弄清楚关系 词在定语从句充当什么成分，是掌握定语 从句的关键。
• 4.先行词是表示地点的名词时（country, school, room…），而关系词代替先行词在定语从句中充当地点 状语，一般用where引导定语从句。也可以用介词＋ which的结构。值得注意的是which前介词的选择是根据先 行词与介词的搭配关系而定。
The room where(=in which)he used to live has now been turned into a museum. The desk where(=on which)I put my bag is his. This is the school where(=in which)I joined the Party. 关系词的选用与判断（续）
