【题目】 —Some people believe _______ green can give us energy.

—I agree. But I wasn’t certain ________ I was suitable for wearing green in the past.

A. that, that B. if, if C. that, if D. if, that

Answer 1

【答案】C

【解析】

试题分析：句意：-有些人相信绿色能给我们能量。-我同意。但在过去我不确定我是否适合穿绿色的。陈述句变来的宾语从句用that作引导，但一般疑问句变来的宾语从句要用if作引导。所以选C。
