At present, the methodological part of English scientific research papers written by students and published by public is generally designed with an independent genre structure. Although it can achieve the expected discussion task, the direction is not clear, and the overall framework of the article is not rigorous and systematic, which leads to insufficient consistency in discussion. Based on this, this paper puts forward the design and practical analysis of the genre structure of the methodological part of English scientific research papers written by students and published by public. Taking the content of English subject discourses as the design guide of genre structure, the basic organizational structure of scientific papers is briefly described, and the basic strategy and thinking process of English papers are formulated in combination with the actual exposition requirements of article methodology. At the same time, the relevance problem is raised. Through the collection of multi-level data and the clarification of genre structure design methods, the limitations of traditional paper genre structure in data collection are broken, and the most authentic and reliable exposition data and information are obtained. On this basis, a comparative study of practice is carried out, and the final research results are obtained by analyzing and comparing the data of the papers, which further promotes the refinement of the research content of the papers, increases the relevance of each chapter, and realizes the integration and practice of the genre structure of English scientific research papers.
