AbstractWith the surging of the second-wave feminist movement which brought into the spotlightthe women of color and women from other developing nations who were seeking femaleindependence and female solidarity,an increasing number of writers begin to focus on thoseformerly marginalized women,especially the colored women.Toni Morrison,for example,is anAmerican writer who is dedicated to writing about African American women as well as AfricanAmerican society,culture and history.Her second novel,Sula,is a typical novel about the bondof sisterhood between two black women.The publication of this novel has initiated the literarystudy on sisterhood,especially the sisterhood between or among African American women,which has never been a major focus of novels before Sula.Therefore,this thesis attempts toexplore the theme of sisterhood in Sula by analyzing the characteristics,necessity,andlimitations of sisterhood,thus demonstrating the significance of female solidarity.This thesis consists of five chapters.Chapter One is the introduction part,where ToniMorrison and her second novel Sula are introduced,the concept of sisterhood is explained,andliterature review and the layout of the thesis are presented.The following three chapters are themain body of this thesis.Chapter Two discusses the typical characteristics of sisterhoodincluding its dominant position and complexity in Sula.Chapter Three explores the necessity ofsisterhood:to begin with,sisterhood plays an essential role in surviving and combating racismand sexism imposed upon African American women;secondly,sisterhood can serve as a solacecompensating for the lack of maternal and paternal love.Chapter Four analyzes the limitations ofsisterhood encompassing the vulnerability before the intervention and coercion of patriarchy andthe fragility in front of different values mainly caused by different upbringings.Chapter Five isthe conclusion which argues that although sisterhood is fraught with complexities and conflicts,it is still significant to strengthen female solidarity in the patriarchal society,and that sisterhoodshould be regarded as equally important as other relationships including the man-womanrelationship and parent-child relationship.Key Words:Sula,Toni Morrison,sisterhood摘要伴随着第二次女权主义运动浪潮的到来，来自发展中国家的有色人种女性开始寻求女性独立与女性团结，越来越多的作家开始在作品中关注有色人种女性。例如，托妮莫里森就是一位致力于研究非裔美国女性的美国作家，她也是历史上第一位获得诺贝尔文学奖的黑人女性。在她的作品中，她还描写了非裔美国社会、文化和历史。在她发表于1973年的小说《秀拉》中，她主要讲述了两位黑人女性：秀拉和奈尔的漫长交往和姐妹情谊。在这本小说发表之前，姐妹情谊很少在文学作品中占主要地位。因此，本篇论文试图分析《秀拉》这部小说中姐妹情谊的特点、必要性以及局限性，并试图对其存在意义进行深入探索，从而进一步强调妇女团结的重要性。本论文由五个章节构成。第一章为引论部分，简述了托妮·莫里森的生平、《秀拉》的故事情节，介绍了姐妹情谊这一概念，提供了文献综述并概括了论文布局。其后，第二、三、四章为论文主体。第二章探讨《秀拉》中姐妹情谊的主要特点：主导性和复杂性。第三章探索姐妹情谊的必要性：首先，姐妹情谊在对抗种族压迫和性别压迫中起到了非常重要的作用：其次，姐妹情谊可以补偿非裔美国女性生命中父母之爱的缺乏。第四章分析姐妹情谊的局限性：第一，姐妹情谊容易受到男权主义社会的入侵和干预：第二，姐妹情谊往往容易受到不同价值观念的阻碍，女性们可能会因为彼此之间思想和价值观的差异而终止友谊。第五章为结论部分，简要总结了论文内容：虽然莫里森笔下的女性情谊存在局限性和脆弱性，但是她仍然对姐妹情谊持乐观态度，并强调在男权社会，姐妹情谊对于维护女性尤其是黑人女性之间的团结起到了至关重要的作用。关键词：《秀拉》、托妮，莫里森、姐妹情谊Chapter One Introduction1.1 An Introduction to Toni Morrison and SulaToni Morrison is an African American writer who has won the Nobel Prize inLiterature.She enrolled at the historically black Howard University in 1949 andgraduated in 1953 with a B.A.in English.Later,she went on to earn a Master of Artsfrom Cornell University in 1955.It was during the 1970s that she had begun wringfictions as part of an informal group of poets and writers at Howard University.Duringher life,she has created numerous notable works including The Bluest Eye (1970),Sula(1973),Song of Solomon (1977),Tar Baby (1981),Beloved (1987),Jazz (1992),Paradise(1997),Love (2003),and Home (2010).She won the Pulitzer Prize and the AmericanBook Award in 1988 for Beloved which was later adapted into a film of the same name.In 1993,Morrison became the first black woman of any nationality who was awarded theNobel Prize in Literature.Her citation reads:Toni Morrison,"who in novelscharacterized by visionary force and poetic import,gives life to an essential aspect ofAmerican reality."In terms of the genre,Morrison exemplifies characteristics of"postmodern feminism"by altering Euro-American dichotomies by rewriting a historywritten by mainstream historians and by her usage of shifting narration in Beloved andParadise.Sula is Morrison's second novel.It focused on the intimate and complex friendshipbetween two African American girls,Sula and Nel,along with a series of stories relatingto life and death,love and hatred,in a mostly black neighborhood named the Bottom inOhio.The story is chronologically divided,starting from 1910 to 1965 and covering thetwo world wars and the second wave of feminist movement.Sula and Nel,despite theirdifferences in upbringings,became fiercely attached to each other during their childhoodand adolescence until Sula's accidentally drowning of Chicken Little made them grow
