( 3 )如果要引导两个非限制性定语从句，第二个 which 前要加 and. He bought a book, which was written by LuXun, and which he decided to give to his friend. 他买了本鲁迅写的书，他决定送给朋友。

3. 名词+ of + which (= of which +名词= whose + 名词)通常放在先行词的后面。

4. 介词+ which 的替代作用。

5. which, when, where 关系词的选择。 关系副词 when 与 where 用于引导定语从句时，往往修饰句中表示地点或时间的名词。但是，有时候在表示时间或地点的名词后面却不能用 when 或 where ，而该用 which 或 that 。

6. 引导非限制性定语从句关系代词 which, as 的选择。

关系代词 as 与 which 引导非限制性定语从句时可以用整个句子作为先行词，指代上文或下文所说的一件事。
