Intensive listening: Transcribe short clips (e.g., TED-Ed talks) to identify weak sounds ("wanna," "gonna") and连读 (e.g., "not at all" → "no-ta-tall"). Extensive listening: Passively listen to English music, podcasts, or YouTube videos (even with background noise) to get used to accents and rhythm. Start with subtitles, then gradually remove them. Focus on grasping the main idea first, not every word.
