1. Review basic grammar: Focus on the parts of speech, verb tenses, and sentence structures. Practice by writing sentences or doing exercises online.

3. Read English materials: Read books, articles, and stories to improve your reading comprehension and expand your vocabulary. Highlight unfamiliar words and look them up.

4. Listen and speak: Immerse yourself in English-speaking environments, such as watching English movies, listening to podcasts, or joining language exchange groups. Practice speaking with a language partner or a tutor.

6. Take practice tests: Use past junior high English exams to assess your strengths and weaknesses. Focus on areas where you need improvement.

By consistently practicing these methods, you can gradually improve your English skills.
