Book Four comprises three units of four lessons each, for a total of twelve lessons. Upon completion of this course, students should achieve a proficiency in the language equivalent to HSK level 4. The recommended instruction time for each lesson is between six and eight hours. Teachers may adjust the pace of instruction based on the background or learning progress of the students. The two main sections of each lesson are the Dialogue and Text, as well as six language practice sections, including Dialogue Practice, Reading Comprehension, Key Language Practice, Listening Practice, Oral Practice and Activities. Supplementary information such as Idiom Notes, Culture Notes and Language Notes are presented wherever relevant. The pre-lesson Learning Goals and lesson-final Progress Checklists provide students with the opportunity to self-evaluate their understanding of the key vocabulary and communication skills presented in each lesson.
