To excel in English at the junior high school level, focus on building a strong foundation in four key areas: listening, speaking, reading, and writing. Regularly practice vocabulary and grammar to improve your written expression. Read English books, articles, and stories to enhance your reading comprehension and broaden your vocabulary. Engage in conversations with peers or teachers to improve your spoken English skills. Additionally, watch English movies and listen to English songs to practice listening and pick up new phrases and idioms. By consistently practicing these skills, you can achieve excellence in English.
