An Ecological Discourse Analysis of College English Textbooks in the Context of Ideological and Political Education—A Case Study of <i>New Horizon College English </i>4

立德树人是教育的根本任务。课程思政要求将思政内容融入非思政课程。高校作为培育人才的摇篮，在推进生态文明建设中已成为重要一环。因此，高校在日常教学过程中，应规范化、长久化、系统化地培养学生的生态素养。大学英语教材是塑造国家形象的重要载体，生态话语分析路径是探索生态化中国形象建构的重要手段。本文基于生态话语分析框架，以《新视野大学英语》第四版第四册读写教程的课文为研究对象，探讨了语篇中的生态素养呈现及其话语表征。研究发现：六个教学单元都结合不同主题融入了差异化的课程思政元素。教材语言作为价值观的载体，生动展现了不同民族的价值理念和行为规范。教材中生态行为素养和生态知识素养的内容较为丰富，也包含一些生态伦理素养和生态情感素养的内容。基于以上发现，本研究为在英语教学中践行生态化课程思政提供了参考。The fundamental mission of education is to foster virtue and cultivate talent. Curriculum-based ideological and political education requires integrating ideological and political content into non-ideological and political courses. As a cradle for nurturing talents, universities have become a crucial component in advancing ecological civilization. Therefore, in daily teaching practices, higher education institutions should standardize, sustain, and systematize the cultivation of students’ ecological literacy. College English textbooks serve as an important carrier for constructing the national image, and ecological discourse analysis is a key approach to exploring the construction of ecologized China’s image. Based on the framework of ecological discourse analysis, this study elaborates the ecological literacy representation and discursive features in the texts from New Horizon College English (Fourth Edition) Reading and Writing Course (Book 4). The findings reveal that the textbooks differentiated ideological and political elements tailored to different themes. College English textbook discourse, as a carrier of values, vividly demonstrates the value concepts and behavioral norms of different ethnic groups. It includes substantial content on ecological behavioral literacy and ecological knowledge literacy, along with some elements of ecological ethical literacy and ecological emotional literacy. Based on these findings, this study provides insights for implementing ecological curriculum-based ideological and political education in English language teaching.
