To improve your HSK 4 Chinese writing skills, focus on systematic practice in vocabulary, grammar, structure, and exam strategies. Below is a structured approach with actionable tips:

1. Vocabulary Expansion
- Learn HSK 4-specific words: Use textbooks like HSK Standard Course 4 or apps like Pleco/Duolingo to master 600+ required words.
- Thematic practice: Group words by topics (e.g., travel, health, technology) and write short paragraphs using them.
- Error correction: Maintain a vocabulary notebook to track misused words (e.g., confusing “已经” vs. “曾经”) and review them weekly.

2. Grammar Mastery
- Key structures: Focus on HSK 4 grammar points like:
- 把字句 (e.g., “我把作业写完了”)
- 复合句 (e.g., “虽然天气冷,但是我还是去跑步了”)
- 结果补语 (e.g., “听懂”, “看见”)
- Exercise: Rewrite sentences using target grammar patterns. For example:
- Original: “I eat breakfast.”
- HSK 4 version: “我每天早上都吃完早饭再去上班。”

3. Sentence & Paragraph Construction
- Sentence expansion: Start with simple sentences and add details:
- Basic: “我去超市。”
- Improved: “昨天下午,我和朋友一起去超市买了水果和零食。”
- Paragraph formula: Use the “总-分-总” structure:
- Topic sentence: “我的爱好是读书。”
- Supporting details: “每天晚上,我会读一小时书。我最喜欢科幻小说,比如《三体》。”
- Conclusion: “读书让我放松,也学到了很多知识。”
4. Writing Practice
- Daily drills: Write 50–100 words daily on topics like:
- “我的一天”
- “我最喜欢的季节”
- “如何保持健康”
- Model essays: Analyze HSK 4 sample essays for structure and vocabulary. Highlight useful phrases (e.g., “一方面……另一方面……”).
- Feedback loop: Use tools like LangCorrect or a language partner to get corrections.

5. Exam Strategies
- Time management: Allocate 10 minutes to plan, 20 minutes to write, and 5 minutes to proofread.
- Template use: Memorize templates for common genres:
- Letter: 开头问候 → 说明来意 → 具体内容 → 结尾祝福
- Narrative: 时间/地点 → 事件起因 → 经过 → 结果
- Avoid common pitfalls:
- Length: Aim for 120–150 words (avoid exceeding 180).
- Clarity: Use simple, direct language. Replace “非常高兴” with “很开心”.
- Punctuation: Practice proper use of 。,!?;:””.
