The method of distinguishing the pronunciation of n and l is as follows:

1. Clearly distinguish the pronunciation of the two phonemes: First, you need to understand the difference in pronunciation of n and l. n is a nasal sound. When pronouncing it, the air needs to be exhaled through the nose and the soft palate is lowered, so that the airflow is emitted from the oral cavity and nasal cavity at the same time. And l is a side sound. When pronouncing it, you need to press the tip of your tongue against the upper gums and raise the soft palate to allow airflow to come out from the sides of the oral cavity and nasal cavity.

2. Practice the pronunciation of a single phoneme: After clearly distinguishing the two phonemes, you need to practice their pronunciation separately. It can be practiced through imitation and repetition. You can find some words containing n and l, such as "no", "noon", "light", and "life", and imitate and repeat them respectively.

3. Improve pronunciation accuracy through tongue twisters: Tongue twisters are an effective pronunciation practice method that can help you improve the accuracy and fluency of pronunciation. You can choose some simple tongue twisters and practice them over and over again until you can pronounce each phoneme accurately.

4. Communicate with native speakers: Communicating with native speakers is one of the best ways to improve your pronunciation. You can find some native English-speaking friends or join language exchange groups such as English corners to practice communication with them. By communicating with native speakers, you can gradually adapt to their pronunciation and intonation, thereby improving your own pronunciation.

5. Use learning resources: There are many learning resources that can help you improve your pronunciation, such as online courses, pronunciation practice software, listening materials, etc. You can use these learning resources for auxiliary exercises to improve your pronunciation level.
