【摘要】：近年来,元话语已经成为语言学及应用语言学各个领域研究的热点话题。元话语在作者和读者交流中发挥着非常重要的作用,许多研究者从不同视角出发或采用不同研究方法对学术语篇中的元话语进行细致的讨论分析(Hyland,1998,2005,2012;Li,Xiuming,2007,2011;GillaertsVelde,2010;Bruce,2010;Lin,2015;HuCao,2015;Kawase,2015;Bal-Gezegin,2016))。然而,对工程类学术语篇中的元话语研究相对较少。因此,本文以Hyland(2005)的元话语分类模式为理论框架,对工程类学术语篇中的元话语进行研究,旨在回答以下三个问题:(1)工程类学术语篇中元话语的整体分布特点是什么?(2)工程类学术语篇中交际性元话语子类别的分布特点是什么?(3)工程类学术语篇中互动性元话语子类别的分布特点是什么?为了回答以上三个问题,本文从工程类六种核心期刊上按照分层抽样的方法抽取了60篇学术论文(2013年-2014年)。文章来自工程类三个学科,即机械工程、土木工程和材料工程,随后运用语料库检索软件AntConc 3.4.3对元话语依次进行检索,采用定量研究方法统计出每个元话语在语篇中的分布频数及频率,通过定性方法来分析元话语分布的异同及原因。通过对语料的分析,得出以下结论:第一,工程类学术语篇中,交际性元话语出现的频次远远高于互动性元话语。这可能是因为交际类元话语的主要功能在于组织语篇,从而引导读者阅读。第二,在交际性元话语中,过渡标记语出现频次最高,这与其主要功能有直接关系,主要是因为作者想以连贯的方式组织语篇来引导读者。在互动性元话语中,模糊限制语出现的频率最高,主要是因为当作者表述其学术成果时,模糊限制语可以减少对别人的一些潜在的伤害。第三,由于工程领域学科间的差异性,不同学科学术论文中元话语的使用也存在差异。研究发现,土木工程学科研究论文的作者使用元话语最多,而材料工程学科领域研究论文的作者使用元话语相对较少。本研究对工程类学术语篇中元话语的使用进行了细致考察,其结果可为元话语研究提供一定启示。同时,本研究也可以帮助英语学习者加强其使用元话语进行语篇组织的意识,也可以帮助作者通过学习使用正确的元话语来促进与读者的有效交流。
[Abstract]:In recent years, meta-discourse has become a hot topic in various fields of linguistics and applied linguistics. Meta-discourse plays a very important role in the communication between authors and readers. Many researchers discuss and analyze meta discourse in academic discourse from different perspectives or using different research methods. However, there is relatively little research on meta discourse in engineering academic discourse. Therefore, this thesis takes the meta-discourse classification model of Hylandan 2005 as the theoretical framework to study the meta-discourse in engineering academic discourse. The purpose of this paper is to answer the following three questions: (1) what are the overall distribution characteristics of meta discourse in engineering academic discourses? (2) what are the distributional characteristics of communicative meta discourse subcategories in engineering academic discourses? (3) interactivity in engineering academic discourses What are the distribution characteristics of meta discourse subcategories? In order to answer the above three questions, 60 academic papers were collected from six core journals of engineering according to stratified sampling (2013-2014). This paper comes from three disciplines of engineering, namely, mechanical engineering, civil engineering and material engineering, and then uses the corpus retrieval software AntConc 3.4.3 to retrieve meta discourse in turn. The frequency and frequency of each meta utterance in discourse are analyzed by quantitative analysis. The differences and similarities of meta discourse distribution and its reasons are analyzed by qualitative method. Through the analysis of the corpus, the following conclusions are drawn: first, the frequency of communicative meta-discourse in engineering academic discourse is much higher than that of interactive meta-discourse. This may be because the main function of communicative meta-discourse is to organize discourse to guide readers to read. Secondly, in communicative meta utterances, transitional markers appear most frequently, which is directly related to their main functions, mainly because the author wants to organize the text in a coherent way to guide the readers. In interactive meta utterances, hedges appear most frequently, mainly because when the author expresses his academic achievements, hedges can reduce some potential harm to others. Thirdly, due to the differences between disciplines in engineering, there are differences in the use of meta-discourse in academic papers of different disciplines. It is found that the authors of civil engineering research papers use the most meta-discourse, while those in the field of material engineering use less meta-discourse. This study makes a detailed study of the use of meta discourse in engineering academic discourse, and the results can provide some enlightenment for meta discourse research. At the same time, the present study can help English learners to strengthen their awareness of the use of meta-discourse for discourse organization, and to facilitate effective communication with readers by learning to use the correct meta-discourse.
