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 which
Look 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
