我们经常可以看到引导定语从句的关系代词 whose 与 of which 相互替代。那么是不是在任何情况下二者都可以互相替换呢 ? 它们之间的区别是什么 ?

   〖思维〗1 . 形式不同。如：

   The house _______ windows face south is our reading - room .

   A . of which            B . whose        C . which        D . its

   此题正确答案是B，不能选择A。选择 of which 时应在名词前加上定冠词 the，也就是说如果名词前有 the 就只能用 of
which。如果名词前没有冠词，就用 whose。如上句题干改为：The house _______ the windows face south is our
reading-room . 此题就只能选择答案A而不能选择B了。

   2 . whose 即可以指人，又可以指物，而 of which 只能用来指物。如：

   The boss in whose department looked down upon women .

   The house whose roof was damaged now has been repaired .

   上面第一句不可用 of which 来改写，第二句可以。可写成：The house of which the roof was damaged has
now has been repaired .

   3 . of which 除了可以表示所属关系外，还可以用来表示整体的关系，而 whose 则不能。

   He borrowed a book of which the author was a peasant .

   In Barcelona the Chinese team got 16 gold medals , of which 12 were won by
women .

   第一句中的 of which 就可以用 whose 来代替。因为这个句子中 of 是用来表示所属关系。可改写成：He borrowed a book
whose author was a peasant。而第二句中的 of which 就不要用 whose 来替。因为这个句子中的 of
不是表示所属关系，而是表示整体与部分的关系。

   4 . 引导非限制性定语从句多用 whose，而很少用表示所属关系的介词 of 加上关系代词 which。如：

   There is a mysterious lake at the foot the hill , whose depth has never been

measured . 山脚下有个神秘的湖，其深度从未测量过。

   如介词 of 不表示所属关系，而是用来表示整体与部分的关系。此时就经常引导非限制性定语从句了。如；

   There are 102 elements found in nature , of which most are metals .

The stories about the Long march , of which this is one example , are well
written .
