2.欣赏中国绘画,应该了解其中计白当黑、浓淡生趣、意境天成等艺术手法和精神追求。

3.美育在中国近代历史上是一个很重要的概念,一直承载了爱国救亡、除弊振新的重任。

4.当下美育应重传统轻西方,融汇西方与民族、古典与现代的文化,形成好的审美教育体系。5.要推动人工智能规模化应用,就必须推动人工智能与各行业融合创新,在制造、农业、物流、金融等重点行业和领域开展人工智能应用。6.美国各执行机构每年与白宫主管预算科技政策办公室沟通,说明优先推动人工智能发展情况,按时列明计划,可期获得该项目预算优先权。7．用金银珠玉来装点堂皇的宫殿庙宇，这种行为使得大量珍贵的人力物力降低为符号的陪衬，只能揭示意义的贫瘠和精神的无力。8．让日常的景色转换成大师的杰作，使普通的词语凝结成千古不朽的诗句，这些审美和艺术创造，体现着人的精神世界的富足。9．“富”的美应该是一种由内而外的富贵气，它是一种自然流露的美，它得自个人长期的、自觉的涵养，也得自社会的普遍氛围，与金钱没有必然关系。1.美育包括美术教育和审美教育,文化是美育的底色和灵魂,不能Unit4
