1 Introduction

Abstract is a condensed version of the content of a paper, which is crucial for international publication and retrieval. Research typically employs Swales' genre analysis theory, focusing on the grammatical structure of abstracts. Abstract writing includes five language steps: background, purpose, methods, results, and conclusion. The research involves specific disciplines, cross-cultural and interdisciplinary comparisons. Domestic research focuses on fields such as environmental science, chemistry, optics, and medicine, but there is relatively little analysis of the genre of abstracts for medical undergraduate students. This study analyzes the differences between the English abstracts of medical undergraduate theses and international medical journal papers through qualitative and quantitative methods, providing inspiration for academic English teaching in traditional Chinese medicine colleges, helping students master academic writing skills, enhance their ability in medical English writing and international academic communication, and promote international exchange of traditional Chinese medicine culture.

2 Research Design

Introduced the research design, including corpus sources, language step analysis methods, and statistical methods. The researchers collected 50 English abstracts of undergraduate theses from the class of 2021 at Beijing University of Traditional Chinese Medicine, as well as 10 abstracts of clinical research and review papers from top international medical journals, to establish a corpus. Analyze the structure of English abstracts through five language steps: background, purpose, method, results, and conclusion, and use AntConc 3.5.8 software to calculate the frequency of language steps and micro language features. Finally, interviews were conducted with 10 students to understand the problems they encountered in writing English abstracts, and Chi Square and Log Likelihood Calculator were used to compare the significant differences in language steps and micro language features between the two corpora.

3 Research Results

A detailed analysis was conducted on the genre characteristics of English abstracts for undergraduate theses in traditional Chinese medicine colleges, and compared with abstracts from international journals. Research has found that structured abstracts account for a relatively small proportion of undergraduate abstracts, while unstructured abstracts are more common, which is inconsistent with the trend of international journals tending to use structured abstracts. In terms of the number of language steps, there is no significant difference in the background language steps of undergraduate abstracts compared to international journals, but the number of purpose, method, result, and conclusion language steps is significantly lower than that of international journals, indicating that undergraduate students have structural deficiencies when writing abstracts.

4 Conclusion

Self built corpus analysis shows that there are differences in structure, language, and interactivity between undergraduate English abstracts from traditional Chinese medicine colleges and international medical journals. In teaching, it is necessary to strengthen genre awareness, explain the structure and language characteristics of papers, and enhance students' academic writing and international communication skills.
