Usage to grammar or usage and grammar? A generative approach to the development and use of formulaic language in second language acquisition.

本项目比较了第二语言习得中公式化语言的使用与语言能力的发展。使用学习者语料库，本研究确定了学习者产品中的FL实例，并分析了生成其句法结构所涉及的在线计算。除了学习者产生的外语外，本研究还比较了这些句法计算在同一学习者的中介语语法中的发展。该项目是第一个采用主流生成方法来研究外语的项目，并借鉴了第二语言处理和心理词汇的含义。

This project compares the use of formulaic language (FL) with the development of linguistic competence in second language acquisition. Using a learner corpus, the study identifies instances of FL in learner productions and analyses the online computations involved in generating their syntactic structure. Alongside learner productions of the FL, the study compares the development of these respective syntactic computations in the same learners' interlanguage grammars. The project is the first of its kind to examine FL by adopting a mainstream generative approach and draws on implications for second language processing and the mental lexicon.
