-------- Wonderfully! I’ve never had one before．

A. a pleasant

B. a more pleasant

C. a most pleasant

D. the most pleasant

答案：

A. a pleasant

(答案→)B. a more pleasant

C. a most pleasant

D. the most pleasant

解析：考查形容词比较级用法。形容词的比较级与否定词连用，表示的是最高级的意思。本题中的not a more pleasant就相当于most pleasnat；句意：—在国庆节期间你到云冈石窟的旅游怎么样？—太棒了。没有比它更让人愉快的旅游了。故B正确。
