本文从美国政治话语入手，分析美国小说最近的转变。作者利用巴赫金的长篇小说话语分析理论和杂声思想，通过考察《苍白的国王》和《我爱迪克》指出，在很多作家的作品中，典型的小说模式，无论主题还是形式都发生了偏移，而该偏移乃社会发展与历史发展使然；另外，还应严肃考察文学批评的规范与传统手法，是否可能被这些作品破坏。
The present paper starts from the discourse of American politics，analyzing the recent transformation of American fiction.With Mikhail Bakhtin's novelistic discourse and heteroglossia，it investigates the Pale King by David Foster Wallace and the I Love Dick by Chris Kraus and concludes that in the work of a significant number of writers，a thematic and formal shift away from representative fictional modes were perceivable；the shift was a response to social and historical developments；and the norms and conventions of literary criticism had been eroded by these work.
