美国梦作为美国民族精神的精髓,贯穿美国文学历史的始终,南北内战赋予了美国梦新的时代内涵。本文试以20C美国南方文学的领军人物威廉·福克纳的《八月之光》为例,来探寻作品中美国梦的主题,进而阐明绝境之下流淌的永恒的人性之光和在荒原异化的境遇下人不忘追逐梦想的执着本质。 As the essence of the American national spirit, the American dream runs through the history of American literature. The civil war between North and South gave the new connotation of the American dream.
