以话语分析为工具，文章对1247篇民国报刊新闻述评样本的文体加以分析，得到了 夹叙夹议和非夹叙夹议两种类型，并细化出偏报道类、偏评论类、报道评论类、纯报道 类和纯评论类五种类别，进而引申出“偏报道类偏评论类何以沉寂”“纯报道类纯评论 类何以退场”和“报道评论类何以主流”等三个问题。继而，以文体生态为路径，辅以 “时、势、人”等因素，文章对此三个问题逐一分析，认为：文体因时革、因势变，并 因人异，属变动之物，民国新闻述评在文体上的诸种变动皆因于此，并认为：夹叙夹议 是新闻述评的核心特征，在保证这一特征的基础上，新闻述评的写法会随时代之因在偏 报道、偏评论和报道评论之间游移。

Using the discourse analysis as a tool, this paper analyzes the stylistic features of 1247 news reviews in the newspaper of the Republic of China. There are two categories in general: narration interspersed with comments and non-narration interspersed with comments, and fve types in detail: report-biased, commentary-biased, reportorial & commenting, reportorial, and commenting. Then, taking the stylistic ecology as the path, supplemented by time, situation, human being and other factors, the paper analyzes three questions: why were report-biased and commentary-biased types few, why did commenting type fade away, and why did reportorial & commenting type become mainstream. This study fnds that stylistic features of news reviews change with time and situation, and human being. Based on the core feature of news review, narration interspersed with comments, the writing method of news review would ?uctuate with the time among types of report-biased, commentary-biased, and reportorial & commenting.
