本研究探讨了医学本科生英语学习策略、自主学习能力、大学英语四级成绩之间的两相关系以及它们的多维关系。Pearson 相关性分析表明，三者之间呈显著两两正相关。多元线性回归分析表明，学习策略中记忆策略、元认知策略和认知策略及自主学习能力中目的要求、目标计划和监控评估对四级成绩具有显著预测力。结构方程分析表明，学习策略对四级成绩和自主学习能力均有显著影响，自主学习能力对四级成绩亦有明显影响。

The relationships among language learning strategies ( LLSs) ，learner autonomy ( LA) and CET 4 scores were evaluated in 212 medical students． Pearson correlation coefficients showed that the binary correlations among these three variables were significantly positive． Multiple regression analysis showed that the subscales of memory，metacognitive and cognitive strategies as well as the subscales of “Aims and Ｒequirements”，“Goal and Planning”，and “Monitoring and Assessment”in LA significantly predicted the CET 4 scores． SEM ( structural equation model) indicated significantly positive associations of LLSs with LA and CET 4 scores，and LA with CET 4 scores
