In tutoring middle- and high-school students from Korea, this workbook is the best I've found for studying English idioms and expressions. Each lesson's true, amazing short story presents new idioms in context, then an eight-panel comic strip illustrates the story. Discussion questions about the story, a summary dictation, and review exercises work together to guarantee that each idiom is read, heard, written, and spoken by my students.I only wish I could find Book 1, because books 2 and 3 are so good!
