ESL：学习者邮件沟通精要

This self-paced interactive learning activity is designed to help advanced ESL (e.g. C1 proficiency level) learners improve their professional email writing skills. Through scaffolded tasks and immediate feedback, learners will practice distinguishing between formal and informal emails, applying appropriate tone, and correcting common grammatical and structural errors. The activity promotes independent learning and pragmatic competence in real-world communication contexts.
