本文基于重形式的互动理论,分析了负反馈、注意机制及修正后输出与二语习得的关系,指出这三个因素对二语习得能够产生促进作用。基于这一假设,采用实验前测-实验-实验后测的研究方法,探究上述三个因素对英语问句习得发展的影响。数据分析结果表明:修正后输出行为和注意机制对英语问句习得有显著的促进作用,而重铸和要求澄清两种负反馈方式对问句习得没有直接影响。 Based on the interactive theory of heavy forms, this paper analyzes the relationship between negative feedback, attention mechanism and corrected output and second language acquisition, and points out that these three factors can promote second language acquisition. Based on this hypothesis, we use the pretest experimental - experimental - experimental posttest to explore the impact of these three factors on the development of English question acquisition. The results of data analysis show that the revised output behavior and attention mechanism can significantly promote English question acquisition, while the two negative feedback methods of recasting and requirement clarification have no direct effect on question acquisition.
