a book for children with a story that is divided into chapters (= separate parts, usually given a number or a title), rather than a book that has many pictures and a simple story told in few words

This is a book that would appeal to a child making the leap from picture books to chapter books. 这是一本能吸引小孩让他实现从绘本到章节书跨越的书。

Our students all read at least one chapter book a week. 我们所有的学生每周至少读一本章节书。
