定语从句中whose做的成分
whose是修饰主语的，定语从句中whose是对主句先行词的所属性进行修饰的。
  释义：(用于问句)谁的，(特指)那个人的。语法：whose用作疑问代词或连接代词时只可用来指“有生命的人的”，意思是“谁的”，其后通常要接名词，如果意思清楚，其后的名词也可省略。例句：I'm wondering whose mother she is then。
  我很纳闷，那么她是谁的母亲呢。whose 是定语从句中一个常用的关系代词，表" …… 的"之意它可以指"人的"，也可以指"物的"既可以引导限制性定语从句，也可以引导非限制性定语从句。一，whose + n 。
  可作主语，宾语，功能与 which ，whom (who )相同。如：Mr King ，whose legs were badly hurt ，was quickly taken to hospital 。The boss in whose department Mr King worked had heard about the accident 。
  二，whose 既可引导限制性定语从句，又可引导非限制性定语从句。如：My uncle whose office we have just passed ，is a lawyer 。我的叔叔是个律师，刚才我们经过他的办公室 。Once there was a wise king whose name was Alfred 。
  从前有一个叫阿尔弗雷德的英国国王。三，whose 代指"……的"，既可以指人，也可以指物。如：Look at the building ，whose roof is white 。看那栋楼，楼顶的颜色是白的。The girl lives in the house ，whose windows face south 。
  那个女孩住在这所房子里，房子的窗户是朝南开的。四，whose 表所属关系指物时，可与 of which 转换，词序一般是：名词+ of whichLook at the building ，the roof of which ( = whose roof )is white 。
  The girl lives in the house ，the windows of which ( = whose windows )face south 。五，whose 不可与 of which (whom )转换的'情况。当 of 不具有"所属"含义时，（如在 hear of ，be proud of ，be fond of ，be full of 等短语中，of 均不表"所属"关系），只能用 of which (whom) 或 which (whom ，who )… of ，切不可盲目用 whose 。
  如：Mary has been married to a scientist of whom you may have heard 。(… < who / whom > you may have heard of … 。) 玛丽嫁给了一位科学家，你可能听说过这个人。
  She has a clever boy of whom she is proud 。她有一个为之骄傲的聪明儿子。六，whose 在定语从句中，有"所属"含义，一般不再与其它限定词罗列使用。当 whose 表"所属"含义时，其本身就是一个限定词，相当于 one's （具体讲是：my ，his ，her its ，our ，your ，their …），而限定词不可罗列在一起使用，whose 也不例外。
  如：John ，of whom my aunt is a distant cousin by marriage ，comes to see us sometimes 。约翰有时来看看我们，他是我姑姑的一个远房亲戚。WHOSE也可以引导定语从句，它相当于前面说的关系代词的所有格形式。
  例：She has an uncle 。 His name is Peter。=She has an uncle whose name is Peter。I like that house 。 Its location is good to me。
  =I like that house whose location is good to me。"WHOSE"引导定语从句的三原则:a。 whose 前要有先行词b。 whose 后的名词要做定语从句的主语或宾语c。 否则whose前应有介词，且该介词也可移至定语从句的句尾。
