连接词作为最重要的衔接手段之一，与语篇结构紧密相连。在过去的几十年里，它的研究受到了极大的关注。一些语言学家如Halliday和Hasan（1976）以及Martin（1983）曾提到，连接词对于体裁中一个阶段到另一个阶段的转换非常敏感。但是关于连接词与体裁成分关系的研究却相当匮乏。因此，本文旨在探究学术论文摘要中连接词与体裁成分的关系。具体来说，本文选定语言学领域三大较权威的期刊，从近三年中随意选取110篇摘要进行分析。作者首先根据Martin（1992）、Martin和Rose（2007）提出的连接词类型理论确定出摘要中的连接词的具体类别。然后运用Martin（1992）的网格图展示方法来呈现语篇的连接结构以及于晖（2003b）提出的摘要体裁结构潜势来分析其体裁结构。通过对比这两种结构，我们可以总结出不同的交互模式，同时也能判断出有潜力区分体裁成分的连接词以及能够标识体裁结构成分转换的连接词。研究结果表明语料中共存在两种交互模式，即未标记交互模式和标记交互模式。此外，内在、外在连接词都有可能识别出摘要中的特定阶段。内在结果连接词和外在地点连接词能分别在一定程度上标识讨论或研究结果到结论的过渡以及研究背景到介绍的转折。内在让步连接词和外在方式、添加及连续连接词分别标识研究背景和研究设计。然而，连接词并不是唯一的识别方式，一些词汇语法形式如介词词组和专有表达也能帮助我们确认特定体裁成分。综上所述，本研究旨在进一步了解语篇结构中的连接词并且希望能对学术论文摘要的书写有一定的指导。但是，这仅是对连接词与学术体裁关系研究的初步探索，后续研究可以扩展研究的话题，研讨更为多样的体裁中的连接词。

Conjunctions, one of the most important cohesive devices, are closely connected with the construction of texts and have received enormous attention in the past decades. A few linguists have mentioned that some conjunctions are sensitive to the transition from one stage to another (Halliday and Hasan, 1976; Martin, 1983). However, the study on the relation between conjunctions and generic elements is under-researched. This thesis therefore, intends to explore the relation between conjunctions and generic elements in research article abstracts. In particular, this thesis targets at three influential linguistic journals and randomly collects 110 abstracts in recent three years. It works out specific types based on the conjunction typology proposed by Martin (1992) and Martin and Rose (2007). Then Martin’s (1992) reticula displaying method is employed to present conjunctive structure of abstracts and Yu’s (2003b) model, adopted for the analysis of generic structure. Through the comparison between these two kinds of structure, we can figure out different interaction patterns, meanwhile conjunctions having the potential to identify stages and mark the boundary of generic elements can be postulated. The results reveal that there exist two types of interaction pattern, unmarked interaction pattern and marked one. Besides, both internal conjunctions and external conjunctions have the potential to identify certain stages in abstracts. Internal consequence and external locative can separately indicate the transition from Discussion or Results of Study to Conclusion and the boundary between Research Background and Introduction to some extent. Research Background and Research Design are frequently found to be featured with internal concessive, external means, additive and successive respectively. However, conjunctions are not the only identification devices, and some lexico-grammatical realizations like prepositional groups and typical expressions are also beneficial for the identification work. To summarize, this study aims at shedding lights on the roles of conjunctions in construction of text as well as the writing of research article abstracts. However, it is still a tentative step towards exploring the relation between conjunctions and academic genre and future researchers can extend the topic to examine conjunctions in various genres.
