Second Language Acquisition Feature Exploration based on Affordance Theory

Affordance theory initially reveals the interaction between biology and environment. With the development of second language acquisition, it is constantly applied to second language acquisition. In language learning, learners acquire knowledge and language according to their own needs. From the perspective of affordance theory, the paper discusses the relationship between the local environments perceived in second language acquisition to help students understand affordance, and in the process of language learning, improve teaching quality effectively. Second language acquisition refers to that learners master one or more languages except for their native language. Second language acquisition began to be studied from the seventy s of the 20th century western gradually. With the deepening of the research, second language acquisition research fuses with other disciplines gradually and is widely absorbed into system study, so as to realize the innovation of second language acquisition research and development. Researchers in second language acquisition mostly study second language acquisition learning process from the perspectives of social science and psychological science, and the main purpose is to understand how learners better master another language after learning English language, and master the characterization of language learning.
