本研究以我国理工科硕士研究生和英语本族语者的理工科英语科研论文引言为语料,对比两类作者在引言中构建研究空间语步及其实现形式的异同。研究发现:(1)学生作者论文引言语类结构的完整性和语步循环性远不及专家作者,并且缺失构建研究空间的核心结构“回顾前期研究”和“指出差距”步骤;(2)学生作者倾向使用嵌入式转述语和表积极立场的转述动词,专家作者倾向使用非嵌入式转述语和表中立或否定立场的转述动词;(3)学生作者倾向使用对前期研究挑战性弱的语言实现形式,专家作者相反。
In this study, we use the introduction of science and engineering English as a research paper to the postgraduates of science and engineering in our country and native speakers of English as the corpus to compare the similarities and differences between the two types of author in constructing the research space and its realization form. The findings are as follows: (1) The introduction of the thesis by student authors is far less complete than the author’s author in terms of the completeness of the grammatical structure and the step-by-step cyclical nature. Moreover, the core structure of the research space is lacking: “review the previous studies” and “point out the gaps” (2) transitive verbs, in which student authors tend to use embedded remarks and the positive position of the table, and expert writers tend to use non-embedded transliteration and transitive verbs of neutral or negative positions in the table; (3) Weak form of language implementation, contrary to expert authors.
