动物科学英语学术论文引言语料库的语步研究

Corpus-based Study of Moves in the Introduction of English Research Articles of Animal Science

运用语步分析法,依照John Swale提出的研究背景-研究空白或局限-研究目的和意义(CARS)引言三语步模式,对40篇动物科学领域的英语学术论文引言中的语步进行了基于语料库的研究。研究表明:宏观结构上,引言部分并不一定严格按照Swale的语步顺序,可以根据主题复杂度实行3个语步的循环,从而展现更清晰的逻辑框架;微观结构上,动物科学英语学术论文引言中的语态和时态已由被动态和一般过去时为主转变到主动态和一般现在时为主。此外,研究还生成了高频动词及其对应句型表,以期为动物科学学术论文二语学习者提供更细致的指导。旨在为扩充教师和二语学习者对目前有关学术论文引言语步知识,认识学术论文体裁特点的重要性提供借鉴,并为语料库在学术论文体裁研究中的应用提供参考。

Move analysis is a major method to conduct the analysis and research on genre. This study reports on an analysis of 40 research articles introductions from animal science fields, using Swale＇ s Create-A-Research-Space（CARS） model （1990）. The results of the analysis reveal macro and micro structure, which has important pedagogical implications. In macro structure, cyclic move stands out though Swale＇ s CARS model still accounts for many of move structures in introduction; in micro structure, active voice and present tense are used more frequently rather than passives and past tense. In addition, this study makes high-frequency verb hst and corresponding sentence patterns in each move in order to provide meticulous guidance for researchers in the field of animal science. The study enriches our current knowledge of move in the introduction of research articles and provides the basis for a corpus-based approach to the study of moves in the introduction of research articles.
