Exercises for Grammar and Vocabulary: Building on the first volume, the second half of the vocabulary and grammar of the new HSK 4 is developed through written exercises. Tips on grammar and word usage introduce many exercises and provide a compact overview. The workbook contains 30 lessons, with each lesson consisting of up to 9 pages of exercises. The organization of the lessons is aligned with the reading book "Ziel HSK 4: Chinese Reading Texts with Vocabulary and Grammar - Part 2," allowing for parallel use of both books. The exercises are designed to illuminate new grammar through various application cases. Each application case is practiced with numerous sentences to reinforce sentence structures and usage. A balanced mix of passive and active learning is emphasized to enhance expressive abilities.
