中文摘要：

哈罗德·品特于1978年创作的《背叛》是一部关于婚姻出轨的伦理剧。剧中杰瑞与爱玛之间的“婚外情”揭示出入是一个斯芬克斯因子的存在，体现出理性意志、自由意志和非理性意志之间的伦理冲突。因“欲”而起的“婚外情”是其自由意志没有得到抑制、摆脱道德责任的非理性意志占据上风的结果。激情过后，自由意志的力量渐渐减弱，理性的回归成为必然。杰瑞的归家选择是其伦理意识回归的表现，其间，理性意志起到了关键性的作用。通过“倒叙”的叙事结构，作者将剧中“婚外情”行为还原至20世纪六十年代及七十年代后期两个不同时代的伦理现场，对之加以客观呈现，说明意志冲突导致或抑制“婚外情”的原因是在不同的伦理语境中形成的。这部剧作对于当代中国构建和谐的婚姻伦理关系也有着重要的道德警示作用。

英文摘要：

Betrayal, written by Harold Pinter in 1978, is an ethical drama. From the perspective of Ethical Literary Criticism, the ＂extramarital love＂ between Jerry and Emma demonstrates that Man is an existence of Sphinx factor, fully embodying the ethical conflicts among rational will, free will and irrational will. Their extramarital relationship results from the uncontrolled free will as well as the irrational will overcoming their sense of moral obligation. Jerry＇s choice of going back home shows the return of his ethical consciousness, and the power of the rational will. By the use of flashback, Pinter tries to guide readers back to the ethical situations of the 1960s and the late 1970s, to illustrate how the conflicts of wills cause or restrain the extramarital love in different ethical contexts. The ethical edifications involved in the play could be of referential value to the construction of harmonious marital relationship in contemporary China.
