Abstract: Works of the first generation writers are labeled as “Recording History of Jewish American Alienation”; while the second ones are known for the theme of “assimilation”. With the growingup of the third generation writers in the end of seventeenth last century，they openly and bravely cry for the return to the Jewish traditions. Under the background of globalization，Diaspora study is developing with new trends. As one of the biggest Diaspora group，the literature of Jewish American also changes accordingly.

Key words: assimilation, diaspora, return of identity, Holocaust, Israel

摘要： 第一代美国犹太文学是犹太美国人的隔离苦难史。第二代美国犹太作家则刻意疏离犹太身份，其作品也被贴上了“同化”标签。上世纪70年代末，第三代犹太美国作家在作品中毫不掩饰对犹太传统回归的渴望，其文学也随之呈现出“回归”趋势。在全球化背景下，随着第四代美国犹太作家的崛起，流散转向逐渐形成，而介于“流散”趋势与“同化”主题之间的“回归”浪潮是研究美国犹太文学历史和未来的重要连接点，其地位和意义非凡。
