本文在条件句分类的基础上,重点讨论以往研究所忽视的条件句的非典型成员——事实条件句。基于前人研究,在分类考察的基础上,从说话者的主观态度、说话者对新信息的认识状态等角度分析这一非典型成员(非现实范畴的条件句式和事实的有标记组配)。最后,尝试探讨汉语条件范畴显赫性的几个显性表现。 Based on the classification of conditional clauses, this article focuses on the atypical members of the conditional clauses neglected by previous researches - the fact clauses. Based on the previous studies, based on the classification and investigation, this atypical member is analyzed from the perspective of the speaker’s subjective attitude and the speaker’s understanding of the new information (the combination of the conditional sentence and the factual marker in the non-realistic category ). Finally, we try to explore several dominant manifestations of Chinese conditional categories.
