Question

Up to now, the poet has written eight poems, three ___ are about American country life.

A．of them

B．in them

C．of whom

D．of which

Answer 1

C

试题分析：考查定语从句，代词+of+关系代词，先行词是poems，所以关系代词是which，句意：直到现在，这个诗人已经写了8首诗歌，其中有三首是关于美国的乡村生活的。选C。
点评：做此类题目首先要弄清楚句式，是不是属于定语从句，如果是定语从句，再判断是关系代词还是关系副词，还有介词后面不能加that或who，要用which或whom。
