A study on the application of lexical chunks teaching in senior high school English writing under the i+1 input model

This study examines the application of lexical chunks teaching in high school English writing under the i+1 input model. English writing assesses linguistic ability, logical thinking, and cultural comprehension, yet students often struggle with vocabulary use and sentence diversity. To address these challenges, this research integrates lexical chunks teaching with the i+1 model to enhance writing skills. A systematic literature review and empirical data analysis confirm its effectiveness in improving accuracy and fluency. Additionally, the i+1 model supports vocabulary acquisition and language learning. This paper provides new insights and practical guidance for high school English teachers.
