《西北》是扎迪·史密斯的又一部佳作,赢得了国内外评论界的好评。本文旨在从后殖民视角出发,重点分析小说中象征英帝国的白人安妮和汤姆。他们普遍表现为物质生活的窘迫,同时沉浸在过去的幻想中,有着严重的自恋情结,且把责任推到有色移民的他者身上,对其充满敌意和排斥。进而得出结论:英国笼罩在保尔·吉尔罗伊诊断的“后帝国忧郁症”中。 “Northwest” is Zaidi Smith’s another masterpiece, won praise at home and abroad critics. This paper aims to analyze the white Annie and Tom, the emblems of the British Empire, from the perspective of post-colonialism. They are generally characterized by the embarrassment of material life, immersed in the illusions of the past, having serious narcissistic complexities and pushing their responsibilities to the other, the colored migrants, with hostility and exclusion. And then came to the conclusion that Britain is in “Post-Empirical Melancholia” diagnosed by Paul Gilroy.
