To pronounce English words correctly in junior high school, you should:

1. Learn the International Phonetic Alphabet (IPA): This system helps you understand and practice the correct pronunciation of each sound in English.

3. Repeat aloud: Practice saying words and sentences aloud. Try to mimic the sounds and intonation of native speakers.

4. Record yourself: Record your voice as you speak English and compare it with a native speaker's pronunciation. This will help you identify areas where you need improvement.

6. Break down words: Learn to break down words into their individual sounds and practice pronouncing each sound separately before putting them together.

7. Study vowel and consonant sounds: There are many different vowel and consonant sounds in English. Practice making these sounds until you can do so easily and accurately.

8. Practice often: The more you practice, the better your pronunciation will become. Set aside time each day to work on your English pronunciation.
