单选题 Your complaint is being ______; when we have anything to report we'll write to you again.
A. looked through B. looked over C. looked after D. looked into

【正确答案】 D

【答案解析】[解析] 本题是说你的投述正在调查当中，当我们有任何事要报告时将会再给你写信。D项“look into调查，观察”符合题意。look in “顺访，顺便看望”；look through“(从头至尾)浏览一遍；详尽核查”；look over“把……看一遍；查看”；look after“照料，照顾，照管；注意，关心”，都与题意不符。
