本研究借鉴口头反馈的研究范式来检验纠错反馈对书面语法形式习得的效果，采用描述图片差 异的任务，以“互动假说”为理论框架，考察中国英语学习者在书面写作中口头纠错反馈对冠词和介词的习得 效果，探讨互动理论下书面写作结合口头反馈的有效性。结果表明澄清请求加元语言反馈的效果优于其他两 种类型的反馈( 直接反馈、提示加直接反馈) ，验证了冠词和介词两类语法知识具有不同的认知属性。

This study has borrowed the paradigm of oral CF to examine the effects of CF on the acquisition of grammatical forms in writing． Based on the " Interaction approach" ，it examined Chinese EFL learners' acquisition of English articles and prepositions with the task of spotting picture differences so as to explore the effects of integrating oral CF into writing． The results show that clarification request plus metalinguistic feedback is more effective than the other two types of oral CF( direct correction， prompt plus direct correction) ，and meanwhile indicate that English articles and prepositions have various cognitive properties．
