定语从句的关系代词
关系代词 ：that,which,who,whose,whom
1. 关系代词whose，引导定语从句时，既可指人，又可指物，在从句中只能作定语；of whom只能指人；of which只能指物，有时whose可以与of whom和of which互换使用。如：

The house whose doors are green is an office building. 门是绿色的那座房子是办公楼。
2. “介词 + whose +名词”引导定语从句。如：

3. 在下列情况下，一般只用of whom和of which。
(1) 定语从句的主语是few, little, some, most, many, much等时，一般只用of whom和of which。
