《中国小学英语教材语法可学性评估》运用当今国际第二语言习得研究领域具有重要影响力的理论一一语言可加工性理论（Proces—sabilitvTheory）对中国国内小学英语教材的语法教学内容进行了较为系统地评估与分析，为教材的评估研究领域提供了以第二语言习得规律为基础的创新性方法，同时也对当前小学英语教材语法教学内容存在的局限性进行了较为系统地探讨，*后提出了一系列具有实际教学法意义的改进建议。《中国小学英语教材语法可学性评估》既为我国小学英语教学及教材编写提供了科学理论依据，又将语言可加工性理论的应用进行了延伸，是一本兼具理论入门与实际应用作用的指导性学术专著。

《中国小学英语教材语法可学性评估》：
The first issue is to differentiate formulaic structures from non—formulaic structures.The criterion used to make the distinction is to check whether the grammatical structure appears in different texts with or without variation.If the structure is provided without variation， it is considered to be an invariant form. Take Howare you？ as an example. This structure is listed as a teaching objective in Unit 3 of PEP English， Book 1 （see Table 5.2）.Since this structure appears in the texts and exercises without any variation， it is marked as a formulaic structure.
