摘　　要：过去,语料库曾经是少数专业人士如语言学或语言测试学专家使用的工具;但现在随着电脑技术的广泛普及和教学理念的更新,基于语料库的研究方兴未艾。语料库的数据统计和分析功能使得对英语教材的评估变为现实。本文主要探讨通过自建语料库的方法,对《PrepEdge Bridging》写作教材的中等频率的词汇难度和分布情况进行评估和研究,以及基于此数据和给教材编写者、教材使用者以及学生提出可优化的建议。Corpus, a one-time unfamiliar concept restricted to only a certain number of professionals, has been gaining mounting momentum and revolutionizing the linguistic and education field. This paper aims to explore the methodology of corpus construction for the purpose of analytical studies of textbook evaluation. Basic functions like the concordance and cluster sections of corpus software AntConc demonstrate the possibility to evaluate the medium-frequency vocabulary difficulty and vocabulary distribution in the PrepEdge Bridging writing textbook. This essay aims to put forward relevant suggestions for improvement in language teaching and textbook compilation.
