The book has 18 lessons, 66 texts and 3 simulation papers for HSK listening test. Exercises are listed before the annotations on words and expressions in order to lead the students to do some extensive listening exercises before understanding the language points and then progress to further listening practices. Through the combination of extensive listening with intensive listening and of teaching with self-teaching, the book provides the students with enough freedom to do options both inside and outside the classroom. The series is accompanied by 8 audio tapes(sold separately from the book).
