学术评价能力动态变化——基于二语学习者硕博学位论文的研究

Dynamic Changes in Academic Evaluative Capabilities —A Study Based on Master’s and Doctoral Theses by L2 Learners

摘要: 在系统功能语言学视角下，投射被视为一种逻辑语义关系，而转述动词则是学术语篇中实现投射的重要语言手段之一。本研究以英语语言学领域的硕士与博士学位论文为对象，聚焦于其文献综述部分中转述动词的评价性使用，旨在探究两者之间的异同及其成因。研究发现：硕士论文倾向于使用风险较低的转述动词以构建研究基础，而博士论文则更频繁地借助转述动词展开批判性学术对话。这些差异主要源于研究深度与创新性要求的不同，以及作者学术训练与能力水平的差异。本研究有助于学生深入理解转述动词的语用功能，提升其学术写作中的人际协商与身份构建能力；同时，也对学术英语写作教学提供了一定的启示。

Abstract: From the perspective of systemic functional linguistics, projection is regarded as a logico-semantic relationship, and reporting verbs are one of the key linguistic means through which projection is realized in academic discourse. This study examines master’s and doctoral theses in the field of English linguistics, focusing on the evaluative use of reporting verbs in their literature review sections, with the aim of exploring the similarities and differences between the two and their underlying causes. The findings reveal that master’s theses tend to employ low-risk reporting verbs to establish a research foundation, whereas doctoral dissertations more frequently utilize reporting verbs to engage in critical academic discourse. These differences primarily stem from variations in the depth and innovation required of the research, as well as differences in the authors’ academic training and proficiency levels. This study helps students gain a deeper understanding of the pragmatic functions of reporting verbs, thereby enhancing their abilities in interpersonal negotiation and identity construction in academic writing; simultaneously, it offers valuable insights for the teaching of academic English writing.
