Abstract:
Mark Twain, the great American realistic writer in the 19th century, is considered as the Father of Modern American Literature and Pioneer of American Humor. His masterpiece The Adventure of Huckleberry Finn has been praised for its remarkable originality.
This thesis tries to deal with the language style and major characters in The Adventures of Huckleberry Finn. In the novel, Huck is the protagonist, who wants to lead a free life, and together with Jim, he comes across a lot of people and events. A very important factor in the novel is the use of vernacular or dialect, which is the focus of this paper. Because there was no native writer ever to write with vernacular before Twain, Twain is regarded as the Father of Modern American Literature. Right from the beginning of the novel, Twain wrote with vernacular, and therefore, this novel is full of humour and excitement. This thesis briefly studies the humorous style，vernacular and the main character. By doing so, I hope to arrive at a better understanding of the novel.

Key words: The Adventures of Huckleberry Finn; Language Style; Vernacular; Humor

摘要：
马克•吐温是美国19世纪伟大的现实主义作家， 他被看作是美国现代文学之父以及美国幽默文学的开拓者。他的巨著《哈克贝里•费恩历险记》因为其艺术上的创造性， 百余年一直受到广泛赞誉。
本论文将讨论《哈克贝里•费恩历险记》中的语言风格和主要人物。小说中，主人翁哈克想要过自由自在的生活，他和黑人吉姆走到了一起，期间遇到了许多的人，发生了许多的事情。小说中非常重要的一点是本国语言的运用，或者通俗的说是方言，这点也是本论文将要讨论的重点之一。原因就在于在吐温之前， 谁也没有用方言去创作，这也是吐温被看作是美国现代文学之父的原因。从小说一开始，吐温就运用方言，小说也就充满了幽默色彩和惊险刺激。论文将从两方面展开分析，幽默风格、方言和主要人物性格。经过这样的分析之后，我希望能够更深入的理解这部小说。
