This paper reports on an investigation of Bai(a minority people in China)junior and senior high school learners' language learning strategies while they were learning English as a third language.The study aimed to explore Bai EFL learners' overall frequency of strategy use and how gender,length of time in English study and ethnicity might affect the strategy choice.The collected SILL Questionnaire data from 502 participants indicated that the overall frequency of strategies employed by Bai EFL learners was at a moderate level and both juniors and seniors preferred metacognitive and social strategies to cognitive, compensation,affective and memory strategies.The results further demonstrated that female participants used more strategies than male ones,and the seniors employed more affective strategies than their counterparts.Major factors that may affect the strategy choice and implications of the study were discussed.
