Second Language Acquisition in the Target Language Environment based on the Theory of Affordances

The Traditional Chinese as a second language teaching put emphasis on classroom teaching and pay little attention to extra-curricular learning. Besides, the existing theories of second language acquisition fail to account for second language learners' effective acquisition in the target language environment. Therefore, on the basis of the theory of Affordances, from the perspective of linguistics, the paper tries to develop the theory of Affordances from the two aspects of active learning ability of self-exploration and language niche. In addition, the developed theory of Affordances is practiced in the second language acquisition in the target language environment. The paper illuminates the effectiveness of second language acquisition in the target language and expounds the theory' representation and functions in second language acquisition in the target language.
