A distribution curve of fuzzy words in management research articles is drawn in accordance with the structures of the articles, and it is proved to be reasonable for tile discourse function of each section. Furthermore, the fuzzy words are divided into three categories and eleven sub-categories, including Category Ⅰ-fuzzy words, Category Ⅱ-fuzzy words＋non-fuzzy part / non-fuzzy part＋fuzzy words, Category Ⅲ-approximators＋fuzzy words. Distribution of fuzzy words varies in different sections of research articles in management science, because of different communicative purposes or discourse functions. Introduction section and Conclusion section have a higher occurrence rate of fuzzy words than Abstract section and Methodology and Data section.展开更多

The differences and similarities between the 2 sections in simple theme, multiple theme, textual theme, interpersonal theme, topical theme and thematic progression were analyzed and concluded. The author believes that the causes of the differences and similarities are the different genre features of the 2 sections and the academic features of the materials selected.展开更多

However, they also have been considered as one of the most difficult part and latest part to be fully acquired by non-native speakers. Because of this reason, a lot of efforts have been made to research into the acquisition of them. In China, researches on the article system were mainly focused on the analysis of functions and description of the usage. This essay intends to explore the distribution and features of English article errors made by Chinese EFL （English as a Foreign Language） learners both horizontally and longitudinally with the hope to find the possible factors which lead to the errors, so as to throw some light on English articles learning and teaching展开更多
