中外林学SCI刊源论文引言部分的体裁分析与对比

A Contrastive Genre Analysis of Introduction Sections in SCI Indexed Domestic and International Forestry Journal Papers

摘要: 本文运用Swales修改后的CARS模型，从宏观语步和微观体裁两方面对比分析中外林学SCI论文引言部分的异同，旨在为林学英文学术论文写作提供借鉴。研究表明：1) 中外林学论文引言部分普遍较长，常多于800词。2) 国内期刊论文存在正文第一部分是背景(Background)部分的现象，其实质为引言(Introduction)部分。3) 在宏观语步方面，国内外论文引言基本都包含了CARS模型的三个语步，即建立研究领域、确立研究地位、占据研究地位，但国内期刊有少部分论文引言缺失第二或第三语步，国外期刊论文引言仅极少数缺失第二语步。4) 在微观体裁特征方面，中外期刊论文引言部分在时态、人称和语态三个方面差异不大，都更多地使用一般现在时、第一人称复数和主动语态。中外林业学期刊论文引言部分呈现了国际学术发展总趋势，国内学者需进一步注意语步完整性。

Abstract: Based on Swales’ modified CARS model, this paper analyzes the similarities and differences in genre of introduction sections between that of the Chinese and foreign forestry SCI indexed papers, to provide reference for forestry English academic writing. The results show that: 1) Introductions in Chinese and foreign forestry journals generally are in the length of more than 800 words. 2) The first part in about half of papers in domestic journal Forest Ecosystems is written as “Background”, but it can be identified as “Introduction”. 3) There are three moves in macro-generic structures of the introductions of most papers in both domestic and foreign forestry journals, namely identifying research areas, establishing research status, and occupying research status, but a few papers in domestic journals papers are more likely to neglect the establishment of the second or the third move in introduction, and the second move of introduction is missing in very few foreign journal papers. 4) In terms of micro genre features, the difference in the frequency of tense, voice and person in the introductions is not significant; both domestic and foreign authors tend to use the simple present tense, active voice, and the first person plural form more often. Both domestic and foreign forestry journal papers show the trends of academic writing, and the Chinese writers should pay more attention to the integrity of genre moves.
