ABSTRACT
The spread of COVID-19 has changed the traditional education pattern, and prolonged home isolation and online learning have brought unprecedented challenges to second language teaching and learning. A sample of 1036 Chinese students from four representative middle schools participated in the research. The results indicated four motivations: intrinsic interest, learning situation, personal development, and immediate achievement. There were significant gender differences in English learning motivation. Moreover, intrinsic interest and personal development motivation had a significantly positive impact on English learning achievement, while learning situation had no significant impact, and immediate achievement motivation had a significantly negative impact. The findings highlight the cultivation of students' learning autonomy and school-family interaction to promote the sustainable development of middle school students' second language learning.
