Abstract: The study explores the effects of motivation modes upon autonomous learning based on questionnaires to 300 second-year non-English majors in Taiyuan Institute of Technology. The statistic analysis shows that seven motivations exert different influences on four dimensions of autonomous learning:motivations of intrinsic interests and immediate achievement have positive effects;motivations of learning situation and going abroad have negative influences;though social responsibility motivation has a significantly positive relationship with identifying teaching objectives, formulating learning goals and monitoring learning process, it has an insignificant effect on learning strategies;motivations of individual development and information medium have zero impacts.
