《天问》是中国文学史中较为奇特的一篇作品,其独特之处在于用韵的连续发问的文体表现形式。但此类问题并非屈原首创,因考察先秦时期传世文献与出土文献便可发现,在屈原之前,此类文体的篇章就已出现。分析并对比这些材料便可知,问体文学的特点为连续发问的形态、韵语的使用、四言为主的句式、内容上的二分结构以及宏壮与奇诡的风格。 “Tian Wen” is a peculiar piece of Chinese literary history whose uniqueness lies in the stylistic expression of successive questions with rhyme. However, such issues are not the first to Quyuan, because of the investigation of the Qin Dynasty handed down documents and unearthed literature can be found before Qu Yuan, the chapter of such style has appeared. Analysis and comparison of these materials shows that the characteristics of Astronomical Literature are the forms of continuous questioning, the use of verse, the four-sentence-based sentence structure, the dichotomy of content and the magnificent and strange style.
