To learn English at the junior high school level, it's important to focus on building a strong foundation in four key areas: listening, speaking, reading, and writing.

1. Listening: Practice by listening to English language audio books, podcasts, or watch English movies with subtitles. This will help you understand the rhythm and pronunciation of the language.

3. Reading: Read English books, articles, and magazines to improve your vocabulary and comprehension. Try to read something new every day to keep your skills sharp.

4. Writing: Write down new words and phrases as you encounter them. Practice writing short essays or letters to improve your grammar and sentence structure. Consider keeping a journal in English to solidify your learning.
