《傲慢与偏见》第一章的核心好句可归纳为以下五点，结合权威来源与经典引用：

开篇名言

"It is a truth universally acknowledged, that a single man in possession of a good fortune must be in want of a wife."

这句名言以幽默方式揭示了当时社会对单身富翁的普遍期待，成为小说的经典开篇。

婚姻观念的讽刺

通过描述单身汉被视作“女儿的财产”，讽刺了当时社会对婚姻的功利性认知，如"he is considered as the rightful property of someone or other of their daughters"。

人物性格的伏笔

本章通过达西的傲慢态度与伊丽莎白的独立见解形成对比，为后续情节发展埋下伏笔，例如："His character was decided. He was the proudest, most disagreeable man in the room"。

语言风格特点

采用幽默讽刺与机智对话结合的手法，如"pride relates more to our opinion of ourselves, vanity to what we would have others think of us"，展现了作者对人物心理的精准刻画。

社会背景的隐喻

通过"good fortune"的限定，隐喻了当时英国社会对财富与地位的重视，以及这种观念对人际关系的深刻影响。
