人教版高中语文必修5《谈中国诗》教案
教师提示：1.这句话的本体不是一般意义上的“中国诗”，即不是指中国诗歌中的某一类作品或某位诗人的作品，而是指中国诗的发展特点。早熟，是指“纯粹的抒情诗的精髓和峰极，在中国诗里出现得异常之早”；早衰，是指“中国诗一蹴而至崇高的境界，以后就缺乏变化，而且逐渐腐化”(腐化，是对诗的思想内容和艺术价值而言的)。这句话，借助比喻和比喻中的对比(“早熟”与“早衰”)，从诗歌发展的角度，简要地说明了中国诗的艺术特征和由此产生的负面影响。2.这句话有两层意思：一是借梵文的《百喻经》阐释中国的艺术和思想体构上的缺欠，旨在批评；二是点明造成这种缺欠的根本原因。“一个印度愚人要住三层楼而不许匠人造底下两层”这样的建筑物就是“飘飘凌云的空中楼阁”，作者以此作喻，批评中国的艺术和思想体构缺乏严密的逻辑性，往往脱离客观实际，没有坚实的基础，其结果必定影响艺术的健康、稳定地发展。
