A. not to remind

B. not to be reminded

C. not reminding

D. not being reminded

答案：

A. not to remind

B. not to be reminded

(答案→)C. not reminding

D. not being reminded

解析：考察动词regret用法。动词regret后面接两个结构，regret to do sth遗憾要做某事；regret doing sth=regret having done sth遗憾做了某事；句意：—Mary患了重感冒。—是吗？我很后悔昨天没有提醒她多穿衣服。根据句意说明使用regret doing sth，而且使用否定式，就是在动名词doing前面加not。故C正确。
