言据性指作者利用语言编码传达所述命题信息的来源及其对信息可靠程度的态度。本研究以言据性为基础,对90篇中美实证类语言学硕士学位论文语料库进行统计,对比分析了两国学位论文中据素的使用特点以及语言呈现方式的特点。结果发现:(1)两国语言学硕士学位论文均使用到感官据素、信念据素、报道据素和推断据素,在据素类型的分布上具有一致性和不均衡性;(2)研究方法会影响感官据素和推断据素的使用;(3)中国硕士生显著多用感官据素,少用推断据素和报道据素,表现出“读者负责型”汉语语篇模式;(4)两国硕士生的语言呈现方式存在使用频率和多样性的差异,且中国学生在使用质量上出现中介语特征。该研究结果对我国语言学硕士培养和学术英语写作教学具有一定的启示意义。
Evidentiality is a linguistic coding of the sources of information stated and the attitude towards the information. Based on a comparative analysis of the evidentials and their language presentations in 90 empirical MA graduation theses in China and the USA, the study finds: (1) graduates in both countries make use of sensory evidential, reporting evidential, belief evidential and inferring evidential with similarity and imbalance; (2) research method adopted by the theses may influence the frequency of evidentials; (3) the Chinese MA students overuse sensory evidential and underuse inferring evidential and reporting evidential, indicating the feature of Chinese reader responsible discourse pattern; (4) there is difference in language presentations and variety in both graduation theses and the Chinese MA students show the tendency of interlanguage. The findings may have some pedagogical implications for MA education and academic English writing as well as its teaching in China.
