文艺创作彰显中国精神，是所有文艺工作者的神圣职责。

近年来，文艺市场“乱花渐欲迷人眼”，庸俗、低俗、媚俗作品“你方唱罢我登场”，抄袭模仿、千篇一律，机械化生产、快餐式消费……种种文艺怪像，正是文艺创作精神缺乏、灵魂缺失的表现。有灵魂，作品方能不朽，失魂丢魄只会使文艺变质变味。唯有让中国精神成为社会主义文艺的灵魂，文艺才能“像蓝天上的阳光、春季里的清风一样，能够启迪思想、温润心灵、陶冶人生，能够扫除颓废萎靡之风”。

彰显中国精神，要聚焦中国梦的时代主题。从当代社会中感人的事迹、典型的人物中寻求丰富的素材，在文以载道的意义上呵护和弘扬社会的主流价值，彰显出信仰之美和崇高之美。要普及和传达正确的历史观、民族观、国家观、文化观，能够增强民族的骨气和底气。在立足中国文化意境、文化精神的同时，认真学习借鉴世界各国优秀文艺，形成世界性的。

结合材料和所学文化生活知识，探究文艺创作应怎样彰显中国精神。
