二语习得主流理论对我国外语教学的启示

On the Mainstream SLA Theories and the Implications for TEFL in China

在第二语言习得理论体系中，有三大学派格外令人瞩目：先天论、环境论和相互作用论。它们以不同的理论为基础，从不同的角度揭示第二语言习得的本质和过程。尽管它们的理论视角不同，得出的结论不一样，甚至大相径庭，但都为第二语言习得的研究和发展做出了十分有益的贡献，其研究成果对于我国外语教学改革具有积极的指导和借鉴作用。当前我国外语教学要解决的主要问题在于如何提高语言输入的数量和质量以及如何充分发挥学习者的学习积极性。

Among different theories of second Language acquisition are three prominent schools, Nativism, Environmentalism and Interactionism, each accounting for language acquisition from a different or even opposite perspective. This article aims to discuss the three schools of theories and assess their implications for the foreign language teaching in China and holds that the problems in TEFL in China call for solutions in two aspects: how to increase the quantity and quality of input and how to bring student roles into full play.
