句子成分分析
But neither advertising brochures nor lyric poetry can ever be reduced to the kind of logic required for computer porgrams.
required 为什么是被动啊?

Answer 1

首先要知道required在句子中的成分,是充当定语的成分.
原句可以这么看：
But neither advertising brochures nor lyric poetry can ever be reduced to the kind of logic.The logic is required for computer porgrams.
两句句子合成一句定语重句,成为:
But neither advertising brochures nor lyric poetry can ever be reduced to the kind of logic which is required for computer porgrams.
省略关系代词which ,那么“is required”就要改为非谓语“required” ,整句成为：
But neither advertising brochures nor lyric poetry can ever be reduced to the kind of logic required for computer porgrams.
其实logic和computer porgrams是一个被需要的关系,即logic is required for computer porgrams.
