Abstract: The Sun Also Rises written by Ernest Hemingway reflects the American society of 1920s vividly. In the novel, the heroes Jake Barnes, Brett, and Romero are the representatives of the Lost Generation. This article, by analyzing the three characters respectively, tries to interpret the dual nature of the Lost Generation. Jake and Brett suffer pains caused by the war and become depressed. Hanging around different bars and hotels, they don’t know the direction of life and even hold a negative outlook on life. They are lost, but that doesn’t mean that they are ruined. Jake doesn’t succumb to the cruel reality. He is hard-working and desires to pursue the true meaning of life. Though Brett experiences misfortune in marriage, she resists and tries to be independent. To a certain degree, Romero’s courage in bull-fight has a positive influence upon them. His bravery urges them to struggle to survive in difficulties. This paper concludes that as victims of the war, these young people are on the surface negative and aimless, but inwardly they never allow themselves to be at the mercy of fate.

摘要：欧内斯特·海明威的著作《太阳照样升起》真实地反映了美国20世纪20年代的社会状况，这部小说里的主人公杰克·巴恩斯、布莱特和罗梅罗是迷惘的一代的代表。本文试图通过分析这三个主人公来阐述“迷惘的一代”的两面性。杰克和布莱特因为战争而受到伤害，从而变得消极。他们整日流连于不同的酒吧和酒店，他们找不到生活的方向，甚至对人生抱有消极的观念。他们迷失但却没有垮掉。杰克并没有屈服于残酷的现实，他努力工作并且渴望追寻生活的真谛。尽管布莱特的婚姻是不幸的，但她坚持并试图去变得独立。在一定程度上，罗梅罗在斗牛中的勇气对他们都有着积极的影响。他的勇敢促使他们在困境中挣扎着生存下去。本文总结出，作为战争的受害者，这些年轻人在表面上是消极的、毫无目标的，但在他们的心灵深处，他们从不让自己听任命运的摆布。
