Abstract：The Adventures of Huckleberry Finn is Mark Twain`s masterpiece. This novel tells the adventures about a little white boy Huck and a black slave Jim, who float down the Mississippi River together. Although the plot of the novel is not circuitous and weird, the simplicity of Twain’s expression is sincere and moving. Some critics pay more attention to the effect of slavery on Jim and the symbolic meanings of the Mississippi River. This paper, however, interprets the progress of the friendship between Huck and Jim, and analyzes the importance of the moral choice made by Huck toward the end of the novel. Besides, this paper also analyzes the problem of racial discrimination and the goodness of friendship in the book.

Key words: racial discrimination; friendship; moral choice
