Abstract:Among Hemingway's writings, the novel "For Whom the Bell Tolls" occupies an important place. Having given up the nihilism he once embraced in his early years, Hemingway set up the new confidence both in himself and society. He actively went into the social practice, in which he found the real material for his novel. He created a new form of narration with his space art different from his former writing style. In his writing, he properly handled the relations among the natural space, the realistic space and the psychological one. With the natural space as the basis, he turned it into a realistic one through magnifying the subject matter, and opened his psychological space through an extension to the inner world of the characters. With his calm viewpoint and smooth writing style, Hemingway revealed the temporary perplexion, blankness, melancholy, grief, desperation and indignation in the depths of the protagonist's heart, accordingly embodied the value of the character as well as the significance of the life, and, simultaneously, Hemingway also fully showed us his personal remarkable talent of art.
