基于语料库的BBC Science Focus科普文章词汇概况及可读性研究
A Corpus-Based Study of Lexical Profile and Readability of BBC Science Focus Popular Science Articles
摘要: 本研究旨在讨论科普文章对于English for Academic Purposes (EAP)教学的应用价值，深入分析其词汇特征和文本难度。研究选取了BBC Science Focus网站的科普文章作为语料，利用AntWordProfiler软件和Flesh-Kincaid公式分别从词汇覆盖率、所需词汇量及文本可读性展开分析。结果显示，科普文本General Service List (GSL)覆盖率为78.69%；Academic Word List (AWL)覆盖率为5.62%；词汇需求分别为5000词(95%覆盖率)和9000词(98%覆盖率)；文本可读性在10.0~10.4之间。这表明科普文章可作为EAP学习的有效的过渡材料，作为桥梁，帮助学习者逐步适应学术英语的词汇与表达。基于此，本研究为EAP教学提供了详细的教学建议。
Abstract: This study aims to explore the application value of popular science articles in English for Academic Purposes (EAP) teaching, conducting an in-depth analysis of their lexical characteristics and text difficulty. The study selected popular science articles from the BBC Science Focus website as the corpus, using AntWordProfiler software and the Flesh-Kincaid formula to analyse lexical coverage, required vocabulary size, and text readability. The results showed that the General Service List of English Words (GSL) coverage of popular science texts was 78.69%; the Academic Word List (AWL) covered 5.62%; the vocabulary size were 5000 words (95% coverage) and 9000 words (98% coverage); and the text readability was ranged from 10.0 to 10.4. This indicates that science popularisation articles can serve as effective transitional materials for EAP learning, acting as a bridge to help learners gradually adapt to the vocabulary and expressions of academic English. Based on this, this study provides detailed teaching recommendations for EAP instruction.
