学术论文引言中人际元话语的跨学科对比研究

基于Hyland的元话语理论和Swales的引言“创建研究空间”模型，以管理学和化学学科语料对比分析了软硬科学学术论文引言中人际元话语的分布情况，并尝试从体裁交际目的视角来解释这些异同。结果发现，作为同一体裁的两学科学术论文引言虽然在人际元话语的语步分布上展现出了很强的一致性，但在除了凸显语之外的元话语资源使用数量上，管理学引言均多于化学引言。这些一致与差异既符合同一体裁共同的显性交际目的，也体现了不同学科属性规约下各自隐性交际目的实现方式间的差异。

A Cross-disciplinary Comparative Study of Interactional Metadiscourse in Research Article Introductions

Based on metadiscourse theory and CARS model postulated by Swales,this study makes a comparative metadiscoursal analysis of RA introductions in management and chemistry,aiming at the similarities and differences between soft and hard sciences from the perspective of communicative purposes.It is found that the distributions of interactional metadiscoursal resources in RA moves in both disciplines demonstrate a strong correlation while metadiscoursal resources in management RA introductions outnumber its chemistry counterpart except boosters.The correlation and differences can be well explained by the overt communicative purposes realized by their similar generic structures and covert ones respectively achieved and shaped by their disciplinarities.
