情景反讽作为反讽的一种主要类型在马克·吐温《哈克贝里·费恩历险记》中的运用成功地推动了小说情节的发展,增加了小说的戏剧性悬念。而且小说中的情景反讽往往又与哈克的少年身份和体现超验主义的浪漫主义色彩象征“自然”的密西西比河有关,由此,它更加凸显了小说的对于所谓“文明”社会虚伪面貌的批判性现实主义主题,深刻昭示了当时美国南方社会盛行的黑人农奴制度和甚嚣尘上的种族歧视的荒谬性。本文依据小说中情景反讽的典型实例,指出小说中情景反讽的反复运用表达了马克·吐温对黑奴制和种族偏见的强烈谴责,深化了小说的种族主义主题。 The use of situational irony as a major type of irony in Mark Twain’s The Adventures of Huckleberry Finn has succeeded in promoting the development of the novel’s plot and increasing the dramatic suspense of the novel. Moreover, the scene of irony in the novel is often related to Haque’s juvenile identity and the romanticism of the transcendentalism symbolizing the “natural” nature of the Mississippi River. As a result, it highlights the fictional hypocrisy of so-called “civilized” society The theme of critical realism profoundly demonstrated the absurdity of the black serfdom and the raucous racial discrimination prevailing in the South American society at that time. Based on the typical example of the scene irony in the novel, this article points out that the repeated use of scene irony in the novel expresses Mark Twain’s strong condemnation of black slavery and racial prejudice, deepening the theme of racism in the novel.
