英国新生代代表作家扎迪·史密斯的新作《西北》一经问世即受到西方评论界的广泛关注。本文以文学伦理学批评为研究视角,在空间关系和人际关系共筑的伦理环境中,探索小说反映的当下英国移民在“主体”与“客体”、“自我”与“他者”、“主人”与“客人”的伦理身份定位上出现的新问题,揭示21世纪的英国人,尤其是第二代英国移民伦理身份选择的复杂性。 As soon as the new book “Northwest”, the new generation representative writer of the United Kingdom, Zady Smith, was published, it was widely concerned by western critics. This essay, based on the criticism of literary ethics, explores the current British immigrants’ reflection of the contemporary immigrants in the ethical environment of spatial relations and interpersonal relations, The new problems appearing in the ethical status of “the Other,” “Host,” and “Guest,” reveal the complexity of the ethical identity choices of the British in the 21st century, especially the second generation of British immigrants.
