In the context of the full implementation of the "Double Reduction" policy, elementary English teachers are urged to update their teaching concepts and methods in the daily teaching process. The goal is not only to help reduce the burden of learning English knowledge for elementary students but also to alleviate their psychological stress. Traditional teaching methods, which are relatively outdated, have not been successful in extricating elementary students from the heavy academic workload. This requires elementary English teachers to focus on cultivating students' abilities to learn English theoretical knowledge efficiently within the limited teaching time and to enhance their practical skills. English reading instruction is a crucial component of elementary education. To ensure the practical implementation aligns with the requirements of the "Double Reduction" policy, teachers need to develop comprehensive teaching plans that integrate in-class and extracurricular reading. This approach aims to guide students correctly in learning English and to boost their enthusiasm for learning, thereby enabling them to master English knowledge precisely within a limited time. This paper explores the importance of integrating in-class and extracurricular English reading in elementary schools and discusses how to effectively carry out this teaching method under the "Double Reduction" policy.
