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：

分詞作狀語(yǔ)時(shí)，分詞的邏輯主語(yǔ)與句子主語(yǔ)必須一致，句子的主語(yǔ)we與compare是主動(dòng)的關(guān)系，故compare應(yīng)用現(xiàn)在分詞形式。When comparing是when we compare...的省略。
