摘　　要： 语料库驱动下的外语在线自主学习模式是指通过词汇或语法结构、语料库和语料库索引工具提供的语境共现、语料库的文本展现(部分有音频或有音和视频)、网络互动的有机结合为学习者提供自下而上(bottom-up)语言学习环境,从而促进学习者对外语的自主和协作学习.本文探讨了提出该模式的现实背景及其理论基础,介绍了适合大学英语学习者自主学习的多样化语料库的开发和应用,着重介绍了教材语料的词性和语法标注及包含文本、音频(和视频)语料和检索工具的多媒体语料库的构建和应用. Corpus-driven Self-access EFL Online Learning is a strategy and model which involves the dynamic integration of vocabulary/grammatical structure, concordancing provided by the use of corpora and corpus tools, view of text （some with audio streaming or video streaming） , and eyber-interaetion to provide a bottom-up learning environment in which learners are encouraged and expected to learn a foreign language independently and/or collaboratively. This paper discusses the practical background and theoretical basis for advancing such a model. The techniques and principles for the development and application of diversified corpora for College EFL self-access learning are also discussed and with particular reference to the tagging and parsing of the textbook corpus and the integration of text, audio （and video） and concordance searches for language learning.
