摘要：马克·吐温是享誉世界的美国文学大师，才华横溢的幽默家。他的一生著作等生，著有大量优秀的长篇小说、短篇故事等。但让广大读者记住马克·吐温的还是他的长篇小说，尤其是他的代表作《哈克贝利·费恩历险记》和它的姐妹篇《汤姆·索亚历险记》。他的作品融幽默与讽刺一体，既富于独特的个人机智与妙语，又不乏深刻的社会洞察与剖析。两篇小说中的主人公—哈克和汤姆是好朋友，但却有着不同的社会经历。在两部历险记中，语言朴实又充满幽默，幽默中又带有讽刺。研究其中的幽默与讽刺，可以更好地了解马克·吐温当时的人生观和世界观，也能更好地了解美国当时的社会状况。

　　　哈克和汤姆同样讨厌资产阶级虚伪、刻板的生活方式，一起追求新奇、浪漫的冒险生活。两部作品还可以说是当时美国社会的缩影。

　　　在马克·吐温的作品中，幽默与讽刺是分不开的，是融于一体的，因此我将两者结合起来研究。作品中的幽默不仅仅是为了幽默与搞笑。马克·吐温将讽刺融于幽默当中并通过幽默来进行讽刺。本课题将从作品的内容、语言、人物的心理及性格等各方面来研究作品中所体现出的幽默与讽刺。
