中外博士论文结论部分参与者导向词块情态特征对比研究

参与者导向词块与表达说话者态度和立场的情态意义关联，其功能在于构建作者与读者关系，拓展语篇对话空间，从而实现语篇的人际互动功能。文章基于系统功能语言学的情态系统，通过自建对比语料库，运用AntConc语料分析工具，对比分析了中外博士论文结论部分参与者导向词块的情态特征。研究表明，中外博士论文作者均善于使用情态化语块和中低值情态语块来表达客观命题的商讨性，而中国博士论文还用意态化词块融合声音介入；语法隐喻方面，双方都会运用客观情态隐喻凸显观点表达的客观性，但本族语者集中在概率类隐喻，而且中国博士论文意愿类隐喻偏多，进一步说明了中国学习者的个人介入性。 

A Contrastive Study of Modal Features of Participant-oriented Bundles in Conclusions of English PhD Dissertations Written by Chinese and NSE Writers

Conveying the speaker’s attitude and stance, participant-oriented bundles are related to the modality, to realize the interpersonal interaction in the discourse enacting the relationship between the writer and the speaker and their negotiation. Based on the modality in SFL and two comparative corpora, the study applies AntConc to the contrastive study of the modal features of the participant-oriented bundles in the conclusions of Chinese and native speakers’ doctoral dissertations. It is shown that Chinese learners and natives both use modalization for the proposition statements and low and medium modal bundles for the negotiation, but the former can use some bundles of modulation to show their personal involvement in the dissertation. For metaphors of modality, Chinese learners use plenty of inclinations to enhance their personal suggestions while the natives mainly focus on the probabilistic metaphors.
