【摘要】 元话语通常被称为“关于话语的话语”,其主要作用是标示话语组织结构、表明交际者对话语的观点及受众的态度。元话语不仅仅是一个语言现象,而且也是一种修辞和语用手段,尤其是常常出现学术口语语篇和学术书面语篇中。对于元话语的研究,在话语分析、语言教育、语用学以及其它研究领域引起了广泛的关注(Vande Kopple, 1985; Crismore, 1989; Cheng, 1997; Intaraprawat, 1998; Hyland, 1998; 2005; Ifantidou, 2001; 2005; ?del, 2006)。但是绝大多数此类研究是针对于书面语篇进行的,并且对元话语功能的探讨也都是限定在某一特定的元话语和与之相对应的语篇或人际功能范围之内。然而,迄今为止,关于元话语在学术口语中作用的研究却很少见,尤其是关于英语课堂教学中教师元话语的研究更是寥寥无几。此外,以功能-语用和二语习得理论为基础的理论框架对英语为外语的口语语篇中的元话语及其在连续语段中的运用和解释也很罕见。近年来有过一些对于英语为母语者的学术讲座中的元话语研究(Mauranen, 2001; Pérez-Llantada, 2006; Aguilar,2008; Hu, 2008; ?del,2010)。但主要是讨论语篇功能对理解学术讲座语篇的作用。以最新的关于学术口语语篇中元话语的研究成果之一为例,?del (2010)通过对比学术口语语篇和学术书面语篇中的人称元话语,归纳总结了人称元话语的23种语篇功能。值得注意的是,他建议今后要对学术口语语篇中的元话语行为及其在语篇中所发挥的教育教学功能,尤其是对英语为非本民族人所带来的益处进行深入研究。他倡导所有使用学术口语或者学术书面语的说话人或作者要熟悉掌握元话语所表达的修辞行为和惯用的语言形式,以此加强对语篇的理解和生成。Hyland(2005)以人际意义为出发点,提出了元话语的人际意义模式及其对元话语的两个方面的分类---交际元话语和互动元话语。依据Hyland的元话语模式及分类,以Halliday的系统功能语言学关于语言纯理功能之说以及语用学和二语习得理论为研究基础,与前人把元话语标记看做为孤立的个体不同,本研究通过对外语教师课堂话语语料库进行考察,试图为解释外语课堂教师元话语的功能---语用---二语习得的多维视角研究提供理论框架。本研究的目的包括解释元话语手段与其相关的语境特征相结合所具有的人际意义潜势,尤其是揭示特定种类的元话语手段在学术口语体语类中所体现的多重功能,为解释外语课堂教师元话语手段在相对广阔的语言环境中通过其相互协调和相互作用来实现其多功能性提供指导性框架,不同于前人对元话语所采取的态度即视元话语标记为孤立的个体,由此扩展元话语的研究领域。鉴于此,本研究设计将围绕以下问题进行:1)元话语是否普遍存在于外语教师课堂话语之中?各类元话语在外语教师课堂话语中的使用情况如何?2)元话语的出现是否可以通过以功能--语用和二语习得理论为基础,在以Hyland的人际意义元话语模式为蓝本进行修改的框架之内得到解释?3)元话语在外语课堂教学中所体现的功能如何?4)除了理论启示外,本研究是否可以提供外语教育方面的启示?具体内容是什么?为了能够提供适合开展研究调查的语料资源,本研究以来自于国内6所大学的24名英语教师的英语专业国家级精品课教学录像为语料来源,对其进行转写自行建立了小型语料库(共计90,435词),并且主要采用‘AntConc 3.2.2w (Windows) 2008’这一检索软件进行了词条检索和频次统计。本研究对10类子项元话语手段出现的频次进行了定量分析,结果表明元话语在教师课堂话语中普遍存在,即每千个词中有196.47个元话语出现,其中互动类元话语为143.42个,交际类元话语为53.05个,分别占元话语总数的73%和27%。另外,研究数据结果显示:介入标记应用频次最高,即每千个词中就出现90.10个,几乎占元话语总数的一半;其次是过渡标记,即每千个词中出现34.81个,占元话语总数的17.72;之后是模糊语(22.47, 11.44%)、结构标记(12.17, 6.19%)、增强语(14.01, 7.13%)、自称语(10.84, 5.52%)、语码注释语(4.90, 2.49%)、态度标记(4.00, 2.04%)、回指标记(0.81, 0.41%)和言据标记(0.36, 0.18%)。同时,本研究通过对语料的定性分析,分别从元话语在微观和宏观、静态和动态层面进行研究,发现元话语的功能在学术口语话语中的表现是多样化的。在较为广阔的语言环境内,元话语手段通过相互协调和相互作用所发挥的多功能性在经过修改的框架内得到了解释,具体表现为语言的交换功能和语言的互动功能,前者包括标明由论点到论据之间的过渡、由传递知识向发布指示之间的转变、由交代事实向得出暂定结论之间的转变和由质疑向解释说明之间的转变;后者包括达成合作交流、建立礼貌和保全面子的氛围、促使有效的‘可理解性输入’和互动的形成;从而通过具有互动倾向的大学课堂话语独白引起外语学习者对‘可理解性输入’的注意和吸收,从而培养外语学习者的语用意识和交际能力。研究发现这一基于语料库的外语教师课堂元话语研究为元话语的研究提供了功能、语用和二语习得等多维度研究视角,将元话语在学术书面语篇的研究拓展至以英语为外语的学术口语语篇的研究领域。本研究为提高外语课堂的教学质量与效果、促使外语课堂教师话语有效地进行‘可理解性输入’、培养外语学习者的元话语意识和策略、增强学习者的语用能力起着积极地促进作用。除此之外,本研究在优化教师话语质量和掌握语料库研究方法方面起到极大作用,具体体现在为实施外语教师发展培训提供了崭新的研究视角与培训内容。更多还原

【Abstract】 Metadiscourse plays an important role in constructing discourse, expressing the speaker’s or writer’s personalities, attitudes and social relations. It is generally referred to as‘discourse about discourse’or‘talk about talk’. Metadiscourse, a linguistic phenomenon and a rhetorical and pragmatic strategy, occurs in everyday language, especially in spoken or written academic English. Studies of metadiscourse have drawn vast attention to discourse analysis, language education, pragmatic studies and many other research fields, which are mainly anchored in written discourse (e.g., Vande Kopple, 1985; Crismore, 1989; Cheng, 1997; Intaraprawat, 1998; Hyland, 1998; 2005; Ifantidou, 2001; 2005; ?del, 2006). In addition, the treatment of metadiscourse tends to focus on very specific categories and link one category with one function, either textual or interpersonal.Research into metadiscourse in spoken academic English, especially in English-for-non-native-language speakers’spoken academic English, such as in EFL teaching classroom discourse has remained largely unexplored (e.g., Mauranen, 2001; Pérez-Llantada, 2006; Aguilar , 2008; Hu, 2008; ?del, 2010). Furthermore, few investigations are framed under functional-pragmatic and second language acquisition theoretical foundations for accounting for the utilization and interpretation of metadiscourse in a broad discourse clustering. Although, recently some researchers have studied metadiscourse in academic lectures, they have been inclined to focus on discourse functions. Take a newly research done by ?del ( 2010 ) for example. He proposes the taxonomy of personal metadiscourse in academic lectures, which consists of 23 discourse functions. However, it is worth noticing that he suggests there should be potential analysis of metadiscoursive acts and their wording to be packaged pedagogically, especially for the benefit of non-native speakers of English. He advocates that“anyone using spoken and written academic English needs to be intimately familiar with the rhetorical acts and recurrent linguistic patterns involved in metadiscourse, both for comprehension and for production”(2010:94). On the other hand, it is clear that EFL teachers’classroom discourse is crucially important in terms of spoken academic discourse for non-native speakers of English, for its function as a teaching medium as well as a language input in EFL teaching and learning. So the research into metadiscourse in EFL classroom teaching is significant.The present qualitative and corpus-based study, which is done in the light of Hyland’s (2005) interpersonal model of metadiscourse and his interactive and interactional division of metadiscourse and based on metafunctions of language proposed by Halliday, pragmatic theories and second language acquisition (SLA) theories, mainly attempts to propose a framework of EFL teachers’metadiscourse in classroom teaching. This study attempts to account for interpersonal meaning potential of metadiscourse with reference to relevant contextual features. Moreover, different from the previous studies of metadiscourse which treat specific metadiscourse markers separately, this study explores the multifunctionality of EFL teachers’metadiscourse markers in classroom teaching, especially that of the cooperation and interplay among various metadiscourse markers in a broad co-text, so as to broaden the scope of metadiscourse studies.Therefore, this study is designed to explore answers to the following questions:1) Is metadiscourse pervasive in EFL teachers’classroom discourse? How are metadiscourse markers used in EFL classroom teaching?2) Can the occurrence of metadiscourse in EFL teachers’classroom discourse be elaborated in the modified framework of Hyland’s interpersonal model of metadiscourse under functional-pragmatic and SLA theoretical foundations? And if so, how can its occurrence be demonstrated from this perspective?3) What are the functions of metadiscourse in EFL classroom teaching?4) Besides theoretical implications,does this study have any pedagogical implications? And what are they?In order to provide an appropriate resource for investigation, the corpus of 24 EFL university teachers’classroom teaching transcripts is built. Through quantitative analyses of the occurrences of ten subcategories of metadiscourse markers in EFL teachers’classroom discourse, the results show that 196.47 occurrences per thousand words of metadiscourse markers in corpus State-Level Quality Courses (SLQC), which falls into interactional dimension and interactive dimension of metadiscourse, with 143.42 interactional metadiscourse markers occurrences per thousand words and 53.05 interactive dimension metadiscourse markers occurrences per thousand words respectively. Meanwhile, the former dimension takes 73 percent and the latter is 27 percent of the total occurrences of metadiscourse markers respectively. Additionally, it is revealed that among the ten categories of metadiscourse markers, engagement markers rank the highest frequency with 90.10 occurrences per thousand words, taking nearly half part of the total metadiscourse markers. Transition markers rank the second highest frequency with 34.81 occurrences per thousand words, taking 17.72 percent of the total metadiscourse. These are followed by hedges (22.47, 11.44%), frame markers (12.17, 6.19%), boosters (14.01, 7.13%), self mentions (10.84, 5.52%), code glosses (4.90, 2.49%), attitude markers (4.00, 2.04%), endophoric markers (0.81, 0.41%) and evidentials (0.36, 0.18%).On the other hand, through qualitative analysis, this study finds metadiscourse markers embody multiple functions in creating an interaction-oriented monologue of non-native speakers’spoken academic English. Within the modified framework of EFL teachers’classroom metadiscourse, the multifunctionality of metadiscourse markers through their cooperation and interplay in EFL classroom teaching is operationalized in a broad co-text. It is found that metadiscourse markers carry out multi-dimensional functions, particularly transactional function and interactional function, which the former consists of sub-functions of signaling transition from a thesis statement to a supporting evidence, shifting from knowledge transmission to directives, from reporting truths to tentative assertion and from questioning to expounding, and the latter consists of sub-functions of achieving cooperative communication and interaction, establishing politeness and face-saving atmosphere, facilitating efficient‘comprehensible input’, motivating notice and promoting interaction.In conclusion, this corpus-based study of EFL teachers’metadiscourse provides us with multiple-dimensional analysis of metadiscourse in EFL classroom teaching as well as theoretical and pedagogical suggestions and implications in EFL teaching, learning and teacher-development program.更多还原
