摘要：Katherine Mansfield is a world famous woman master of short stories in English literature. Her stories are sensitive revelations of human behaiour in quite ordinary situations, through which we can glimpse a powerful and sometimes cruelly pessimistic view of life. miss brill is one of her short stories published in her collection of stories entitled The Garden Party and Other Stories （2007）, describing an afternoon in the life of a middle-aged spinster who visits the public park on a weekly basis, leading to her reassessment of her view of the world and the secular reality. Short as it is, it is really worth carful analysis and appreciation. This paper will mainly deal with the theme--alienation that the story conveys in two aspects： some obvious alienate elments in miss brill, in which some background information is provided; some less obvious alienation in miss brill, in which a detailed analysis is made into the story to reveal its alienation.
