普通话是国家通用语言,能说标准的普通话是师范生必须掌握的一项基本技能.基于调查对象的数据分析显示:少数民族师范生普通话水平整体不高,大部分学生学习普通话时缺乏开口自信,存在自卑心理和一定的畏难情绪,难以突破"高原现象".学校应加强普通话推广力度,营造良好的校园语言环境;普通话教师应该坚持课程教学改革,不断探索新的教学方法;少数民族师范生要树立正确的语言学习观,重视普通话学习,消除应试心理.全面提升少数民族师范生普通话运用能力,增强其文化认同,进而铸牢中华民族共同体意识.
F.W.尼采和W.B.叶芝的艺术观在文化意义上存在深刻的相通性,在内容实质上则存在明显的差异性.在面临现代性危机时,尼采和叶芝都认为只有艺术能赋予人生和世界于意义,从而为人生和世界作审美之辩护.他们信仰日神和酒神,相信艺术能拯救人生,并使生命永恒.二者的差异性在于尼氏艺术观重视艺术的形而上慰藉和美化功能,叶氏艺术观强调艺术对心灵的净化作用.比较二人艺术观的异同,不仅有助于发现人类共同的"诗心"和"文心",更有益于促进不同文明之间异质文化的互补性.
嵇康《声无哀乐论》的所有论点,其实皆根基于音乐的本质是气这一观念.首先,音乐是天地和合过程中禀气而生成的客观物质,能独立于人而存在.人自身的情感,无法影响到音乐所具备的客观独立性.其次,音乐与人情感的关系是,旋律节奏的"舒急"会使人产生"躁静"之反应.人一旦进入"躁静"状态便会失去平和,从而将事先已积压在内心但并未表现出来的情感状态进行显露.音乐的教化作用、道德意义只表现在是否能帮助人实现平和,这也是雅乐与郑声的根本区别.最后,嵇康与儒家皆提倡以乐为教,二者的分歧主要体现在对乐这一概念的定义上.嵇康并不否定乐教的价值,而是要对究竟什么是乐,音乐与人内在究竟存在什么关系,如何具体实现乐教等根本问题提出异议.嵇康试图以一种符合于其持有的气化宇宙论、自然哲学的音乐观念与乐教主张取代儒家乐教,这是其"越名教而任自然"的一种表现.
