如不一致,请说明理由。

(21分,每题3分)1.选项:(2014·安徽卷第3题B项)古代思想家反对“文胜质”的倾向,认为繁杂的技术具有炫目的迷惑性,“炫技”势必干扰人们对于“道”的持续关注。

原句:古代思想家认为,繁杂的技术具有炫目的迷惑性,目迷五色可能干扰人们对于“道”的持续注视。

他们众口一词地告诫“文胜质”可能导致的危险,这是古代思想家的人文情怀。

当然,这并非号召艺术拒绝技术,而是敦促文化生产审慎地考虑技术的意义:如果不存在震撼人心的主题,繁杂的技术只能沦为虚有其表的形式。

对比结果:不一致理由:选项把“众口一词地告诫”直接换成“反对”;原文是“可能”,到选项中变为“势必”,这是错误的。

2.选项:(2013·天津卷第7题B项)“微博粉丝”和传统“粉丝”都能获得一种投射在偶像身上的替代性满足,在追星的过程中实现自我认同。

原句:换句话说,“粉丝”对偶像“评论”,为其争取人气,照亮星途,既能获得一种投射在偶像身上的替代性满足,也是另一种形式的自我实现。
