It has often been claimed that conditionals have a special relation to modality. This study tests this claim empirically by examining the frequency of modal marking in a number of conditional and non-conditional structures using a corpus-based approach. It then seeks to provide explanations for the emerging frequency patterns in light of the tenets of two linguistic theories: Lexical Grammar and Construction Grammar. This juxtaposition was motivated by the substantial overlap in their tenets: both take into account meaning (semantic and pragmatic), as well as lexical and grammatical factors.

如果条件和模态：频率模式和理论解释

人们经常声称条件句与情态有着特殊的关系。本研究通过使用基于语料库的方法检查许多条件和非条件结构中模态标记的频率，凭经验检验了这一主张。然后，它试图根据两种语言理论的原则来解释新出现的频率模式：词汇语法和结构语法。这种并置的动机是它们的原则有很大的重叠：都考虑到意义（语义和语用），以及词汇和语法因素。
