问题补充：

The poor living in the mountain top is covered with green trees.

A. are; which

B. are; of which

C. is; whose

D. are; whose

答案：

A. are; which

B. are; of which

C. is; whose

(答案→)D. are; whose

解析：考查主谓一致和定语从句。定冠词the+形容词表示一类人的时候，做主语谓语动词用复数形式。第二空定语从句的先行词是the mountain，后面定语从句中的名称top前面缺少定语，故使用whose引导定语从句，在句中做定语。句意：那些穷人住在顶部覆盖着绿树的山里。故D正确。
