—.I’m glad you enjoyed it.

A. All the best

B. It is nothing

C. No thanks

D. Very well

答案：

A. All the best

(答案→)B. It is nothing

C. No thanks

D. Very well

解析：选B。句意：“非常感谢你的书，我觉得它非常有趣。”“不用谢，你喜欢它我非常高兴。”根据句意，答语的前句应选择一个用来回答表示“感谢”的客套语句。A选项“All the best”为祝酒或送行时的用语，意思是“万事吉利，一路平安”；C选项“No thanks”为中国式英语，不符合英语的语言表达习惯；D选项“Very well”意为“好吧”，与上下文的场合、文意不符；B选项“It is nothing”意为“这没什么，不用谢”，符合上下文语境，故答案选B。
