If you still remember the time of the accident, please tell us. We would your help.

A. approximate; appreciation

B. approximately; appreciate

C. approximate; appreciate

D. approximately; appreciation

答案：

A. approximate; appreciation

B. approximately; appreciate

(答案→)C. approximate; appreciate

D. approximately; appreciation

解析：句意：如果你仍然记得事故的大概时间，请告诉我们。我们会很感激您的帮助。Approximate可作形容词表示大概的，此处修饰名词time;而第二个空前有would,所以填动词原形appreciate。故选C。
