摘要

英语已成为国际化语言，英语演讲也毫无疑问扮演着越来越重要的角色。演讲又分很多种，其中影响最大、最能引起大家关注与轰动的要属政治演说，政治演说的目的主要在于使听众信服并按演说者的意图采取行动。这样的演说必需有力、具有强烈的煽动性。为达到此效果，演讲者常常借助于修辞手段，演讲文体中的修辞手段的多样化旨在使演讲更有感染力。
奥巴马在2008年11月5日下午成功赢得美国总统大选，并在芝加哥格兰特公园举行盛大的集会，发表以“美国的变革”为主的获胜演说，堪称演讲经典。奥巴马在演讲中运用了大量的修辞，本篇论文以获胜演说为题材，运用定性与定量分析法，分析演讲词中修辞手法的运用及效果。
演讲词中主要有三种修辞结构，分别是语义修辞、句法修辞和语音修辞。其中语义修辞包括明喻、暗喻和拟人，句法修辞包括对偶、对比、重复、排比，层递，语音修辞有头韵和尾韵。通过统计，发现句法修辞使用最为频繁，其次是语音修辞，再次是语义修辞。句法修辞中，大量使用了重复、排比、对比。总体来讲，大量的使用修辞手法，大大增强了政治演说的感染力，使演说词气势恢宏，激情四射，有厚重的历史感。
最后，奥巴马非常擅长把两种或者两种以上的修辞格组合起来使用，达到一种非常强烈的修辞效果，从而更好的说服听众。
