重述是近年来二语习得研究中的热点话题, 也是课堂上大量使用的反馈形式。该文深入讨论了重述的概念和性质, 分析了与之有关的理论研究背景, 回顾和介绍了国外对重述有效性研究的描述性和实验性研究成果。最后总结出应在分析影响因素的基础上看待重述在二语习得中的作用; 应结合二语习得理论将重述的研究拓展到认知心理等多个领域, 从而更深层次地、全面地分析审视重述对二语/ 外语发展的有效性。

Recasting has been an issue of intensive inquiry in SLA research in recent years. It is empirically found to be a predominant w ay of providing feedback for FL / SL learners in various learning contexts, especially in classroom settings. This paper attempts to provide a wide ranging review of a descriptive and experimental research on the effectiveness of recasting in the second language acquisition and foreign language learning, payng paricular attention to how recasting has been defined and its related theoretical background. Finally it comes to a conclusion that the effectiveness of recasting should be analyzed by
taking into account many other factors and by combining it with the cognitive aspect.
