摘要:杰克·伦敦是美国最富有批判精神的现实主义作家之一, 他所生活的年代正是美国从内战的混乱中爬起，迎来新的经济高速发展的时期。然而那种歌舞升平，一片繁荣景象背后，却处处隐藏着危机。杰克·伦敦通过自然主义写作手法将自己的视线聚焦在被残酷的物欲社会所打倒的、被淘汰的那个群体。本论文通过分析《白牙》，让人们领会到其中绝妙的自然主义写作手法，这种风格艺术不仅运用在对主人公性格的描述上，也贯穿于整个故事的结构之中。

　　　对《白牙》中的自然主义写作手法做系统的分析：以作家的背景，小说的自然环境，故事内容，主人公的成长经历为依据，旨在阐明这类写作手法的特点，从而帮助读者认清现象背后的规律以及事物的成因。
