Question

(2006年浙江高考，5)When ________ different cultures, we often pay attention only to the differences without noticing the many similarities.

[　　]

A．compared

B．being compared

C．comparing

D．having compared

Answer 1

答案：C
解析：

分词作状语时，分词的逻辑主语与句子主语必须一致，句子的主语we与compare是主动的关系，故compare应用现在分词形式。When comparing是when we compare...的省略。
