whose引导定语从句可以指物吗
请看下面这道题：
I saw some trees |||||||||| leaves were black with disease.
A. its B. whose C. hisD. the
剖析：此题应选B。容易误选A。很多考生觉得，关系代词whose和who，whom一样，只能指人，不可以指物。
事实上，用作关系代词的 whose 与 who，whom不同，它不仅能够指人也可以指物(用作定语)：
There are some students whose questions I can’t answer. 有的学生的问题我不可以回答。
Can you see the mountain whose TOP is covered with snow? 你看得见山顶上覆盖着雪的那座山吗?
Here is a word whose meaning escapes me. 这里有一个词，我一下想不起它的意思是了。
当先行词为物时，其后引导定语从句的 whose＋n. 也可换成 the＋n. ＋of which / of which＋the＋n.：
■窗户破了的那座房屋是空的。
正：The house whose windows are broken is empty.
正：The house the windows of which are broken is empty.
正：The house of which the windows are broken is empty.
但假如 whose所修饰的名词中心词之前有数词或其他限定词，则不需要 whose，而用of which：
There I saw a large table，two legs of which were broken. 在那里我看见有一张大桌子，其中有两条腿断了。
