His first book next month is based on a true story.

A. published

B. to be published

C. to publish

D. being published

答案：

A. published

(答案→)B. to be published

C. to publish

D. being published

解析：

考查非谓语动词。此处是非谓语动词作后置定语，由时间状语next month可知所填非谓语动词表示将来的动作，故用动词不定式；其逻辑主语是所修饰的名词book，不定式与逻辑主语是被动关系，故用不定式的被动式，故选B项。
