What is called “modern civilization” is not the result of a balanced development of all man's nature, but accumulated knowledge applied to practical life. (研考英语试题) [原译]所谓“现代文明”不仅是整个人类本性得到平衡发展的结果，而且是把所积累的知识运用到实际生活中的结果。(研考答案) not . . . but 具有“不仅……而且”的含义吗？
并列连词 but 单独使用时作“但是”“然而”解，但是跟 not 连用时，则作“而是”解。“not...but”一般可以译为“不是……而是”，即否定前者，肯定后者。例如：
-
It is not water, but alcohol. 这不是水，而是酒精。
-
He refuses to consider sufficiently the wants of the customer, who must buy, not the thing he desires but the thing the English gentleman wants to sell. 他们不充分考虑顾客的需要，顾客必须买的并不是他们所希望买的东西，而是英国绅士想要卖的东西。
-
Some satellite relay stations relay radio waves to the earth but they receive the waves not from the earth, but from other space. 某些卫星中继站向地球转播无线电波，但它们不是从地球而是从外层太空接收无线电波。

Harry stared at the creature, filled with wonder, not at her strangeness, but at her inexplicable familiarity. (J. K. Rowling, Harry Potter and the Deathly Hallows) 哈利盯着这个生灵，心中充满了好奇，倒不是因为她陌生，而是莫名地觉得她很熟悉。（《哈利·波特与死亡圣徒》）
[试译]所谓“现代文明”并非人的全部天性均衡发展的产物，而是所积累的知识应用于实际生活的结果。
