some historic buildings possess exceptional esthetic value a

Some historic buildings possess exceptional esthetic value and mere replication can by no means demonstrate the superior craftsmanship in them as vividly。本句意思是：有些历史建筑具有特殊的美学价值,只不过仿造建筑决不能像古代建筑那样能够鲜明地作为其中的高超技艺的范例。in them = in the historic buildings 在这些古代建中as vividly = as vividly as the historic buildings can demonstrate（像古代建筑那样能够鲜明地作为范例一样）,这是为了避免重复而省略部分词语的比较状语从句。
