叙事学理论作为研究叙事类作品的文学理论，对不同类别的中外小说的解读都起到重要的指导意义。中国不少古典小说无疑是中国小说作品里最经典的存在，其中，《水浒传》中《林教头风雪山神庙》一回多年来均被选入教材，在众多古典小说选文中，这一回的经典性无可置疑。本文以教材中的经典古典小说《林教头风雪山神庙》为例，基于叙事学理论，运用文献研究法、比较分析法来探究古典小说人物性情变化的解读思路，力求为古典小说人物性情形象方面的教学提供一点新的思路。本文主要内容共分为四个部分：前三个部分分别从叙事视角、叙事时间、叙事空间三个角度出发，对《林教头风雪山神庙》中林冲性情由忍到狠的变化进行分析。其中，从叙事视角来看，林冲在由忍到狠的性情变化下仍保持着理智，并完成从幻想到清醒的转变；从叙事时间来看，林冲内心的矛盾促成其性情向狠转变，林冲最终必定走向反抗之路；从叙事空间来看，林冲从以山神庙为中心的外层空间转移到其内层空间过程中，性情也发生了由忍性占主导到狠性爆发而上的变化。第四部分点明了三个角度的教学启示，并对研究过程中存在不足进行反思。

       As a literary theory for the study of narrative works, narrative theory plays an important guiding role in the interpretation of different categories of Chinese and foreign novels. Many Chinese classical novels are undoubtedly the most classic existence in Chinese novels. Among them, in All Men Are Brothers, "The Temple" has been selected into the textbook for many years. In many classical novels, the classic nature of this time is beyond doubt. This paper takes the classic classical novel "Lin Snow Mountain Temple" in the textbook as an example, based on the narratology theory, using literature research and comparative analysis to explore the interpretation of the temperament changes of characters in classical novels, and strives to provide a new idea for the teaching of characters in classical novels. The main content of this paper is divided into four parts: the first three parts analyze the changes of Lin Chong from the narrative perspective, narrative time and narrative space to ruthless. Among them, from the perspective of narrative, Lin Chong still keeps reason under the change from tolerance to ruthless, and completes the transition from fantasy to sober; from the narrative time, the inner contradictions of Lin Chong contribute to the change to ruthless, Lin Chong must eventually go to the road of resistance; from the narrative space, Lin Chong moved from the outer space to the inner space, and the temperament also changed from tolerance to ruthless. The fourth part points out the teaching enlightenment from three angles, and reflects on the deficiencies in the research process.
