中文摘要:口语是英语学习成功与否的重要标志，而流利度是评价英语口语水平的一个重要的方面。随着中国加入世贸组织和成功举办2008年的奥运会，英语口语流利度越受重视。

　　　目前，国内外已对流利度这方面进行许多研究，主要涉及影响英语口语流利度的因素，英语口语流利度与复杂度、准确度三者之间的关系，提高流利度的教学模式等，多数是从外因探讨如何提高英语口语流利度。

　　　影响英语口语流利度的因素从大方向分为内在因素和外在因素。我国许多大学生在经过多年的英语学习后，口语尚未达到流利的程度。针对此现象，本文从学生自身情况出发，结合已有的研究，通过归纳，分析影响流利度的内因和外因，并提出提高大学生英语口语的流利度策略。

希望本文的研究结果，可为高校学生提高英语口语流利度提供合适的方法。
