C. Good luck to me

D. I have no idea

答案：

A. It couldn’t be better

(答案→)B. It couldn’t be worse

C. Good luck to me

D. I have no idea

解析：句意：--你昨天去颐和园玩的怎么样？--非常糟糕（不能再糟糕了），我跟我那80岁的祖父母走散了。It couldn’t be better是最好的了； It couldn’t be worse是最糟糕的了；Good luck to me祝我好运； I have no idea我不知道。这里根据空格后的一句话我跟我那80岁的祖父母走散了，可知这是一件糟糕的事情，根据句意故选B。
