本文运用文体学中二元论分析方法，从词汇、语法、修辞手段、衔接和语境四方面，就亚伯拉罕?林肯在1863年11月19日在葛底斯堡国家烈士公墓落成典礼仪式上的演说进行了文体分析。分析表明其语言比较正式、庄重。虽然语言结构趋于复杂，但词汇难度系数属于容易范围，并不晦涩难懂。由于采用了一些修辞手段，语言比较生动形象。

This paper aims at exploring stylistic features of Abraham Lincoln’ Gettysburg Address by applying the analysis methods of dualism in stylistics. The analysis is done from the following four respects: lexis, grammar, rhetorical devices and cohesion and context. And we find that Abraham Lincoln’ Gettysburg Address belongs to formal style. Though its structure tends to be complicated, its fog index belongs to easier category; therefore its language is not very hard to understand. Owing to the use of a lot of rhetorical devices, its language is lively and impressive.
