【题目】 His first book _______ next month is based on a true story.
A. published B. to be published
C. to publish D. being published
在线课程【答案】B
【解析】
试题分析：考查分词做定语。His first book与publish构成被动关系，用动词不定式的一般形式的被动语态表示被动和将要发生的动作，相当于一个定语从句。to be published next month="which"will be published;句意：上个月出版的他的第一本书是以一个真实的故事为基础的。故选B。
