新闻具有真实性、时效性和准确性的特点，一直是文体学与语篇分析关注的对象。本文收集了2021年第一季度《经济学人》中所有的新闻标题,以文体学前景化理论为指导,运用归纳分析和对比分析等方法,对其文体特点进行了语相变异、词汇变异、句法变异、语义变异、语音重复与句法重复层面的分析。研究发现，新闻标题的文体特点在准确表达新闻内容，增强标题表现力和激发读者阅读兴趣等方面起着重要作用。本研究既可以帮助我们增强对新闻标题及其语言特征二者关系的理解，又有利于探索发掘语言创新，从而为英语新闻标题的前景化解读提供更多参考意见。

    News has the characteristics of authenticity, timeliness and accuracy, and has always been the analysis object of stylistics and discourse analysis. This paper collected all the news headlines in The Economist in the first quarter of 2021 and analyzed their stylistic features at the levels of graphological deviation, lexical deviation, syntactic deviation, semantic deviation, phonological overregularity and syntactic overregularity by using inductive analysis and comparative analysis method, under the guidance of foregrounding theory. The study finds that the stylistic features of news headlines play an important role in accurately expressing the content of news, enhancing the expressiveness and stimulating readers’ interest in reading. This study can not only help us enhance our understanding of the relationship between news headlines and their linguistic features, but also explore language innovation, so as to provide more references and new ideas for the interpretation of English news headlines from the perspective of foregrounding theory.
