Under the requirements of China’s current educational reform, the cultivation of core competencies in English teaching emphasizes interdisciplinary learning. Research on English reading teaching from an interdisciplinary integration perspective actively responds to this trend and holds significant practical value. By integrating knowledge from various disciplines into reading reading teaching, this approach transforms the monotony of traditional teaching, enhances teaching effectiveness, and provides innovative strategies for junior high school English reading. This thesis takes the 2024 New Edition Yilin Junior High School English Textbook for Grade 7, Volume 1 as an example to explore interdisciplinary teaching in junior high school English reading from three aspects: necessity, principle and strategy, aiming to help students build a diversified knowledge system, cultivate thinking ability, and thereby promote the all-round development of students. Interdisciplinary integration not only aligns with the developmental trends of basic education, but also provides referential models for English curriculum reform.
