"When _______ different cultures, we often pay attention only to the difference without noticing the many similarities．
A. compared
B. being compared
C. comparing
D. having compared"

Answer 1

答案C
思路分析：从when和逗号可知，此题考查非谓语动词作状语，因为主句的主语we与compare是主动关系，故排除选项A、B，compare表示的动作与谓语动词同时发生，故排除选项D。深化升华：现在分词作状语时，其被动式即being done表示主句的主语与分词所表示的动作之间是被动关系，且与谓语动词同时发生，完成时则表示分词的动作发生在谓语动词之前。
