北京市东城区2017—2018学年度第二学期高三综合练习（二） 语文 2018.5 本试卷共10页，150分。考试时长150分钟。考生务必将答案答在答题卡上，在试卷上作答无效。考试结束后，将本试卷和答题卡一并交回。 一、本大题共8小题，共24分。 阅读下面的文字，回答1—8题。 材料一 墨作为书写工具，同时也是重要的文化传承载体，已有几千年的历史。殷商时代的甲骨文就以石墨、朱砂填色。汉代纸料发明后，出现了一种以漆烟和松煤制成的丸状墨，这是日后用墨的滥觞．。 唐代是文化交流最广泛的朝代之一。唐末奚超避乱至歙州，见此地多松且质优，新安江水质极佳，因此留在此地制墨。因墨的主产区为歙州，故得名“歙墨”。其后奚超之子改进捣烟、和胶的方法，制成了“拈来轻、嗅来馨、磨来清”“丰肌腻理、光泽如漆”的佳墨。制墨工艺的改进，让书写更加流利，也加快了文化的传播速度。 宋室南渡后，宋墨的制作技艺臻．于成熟。制墨业的繁荣表现在三个方面：第一，油烟墨的创立，开辟了中国制墨业的新领域。千百年来，制墨主要以松烟为原料，由于长年累月取松烧烟，致使松树被砍伐殆．尽，新的制墨原料——桐油烟便应．运而生。第二，制墨从业人员众多，名家辈出。宋代制墨名家见诸史册的多达百余人，他们在选料、配方、烧制、用胶、捣杵等工艺方面，都有独到之处。第三，达官贵人及文人墨客与制墨工匠切磋技艺，促进了制墨技艺的发展。创造“瘦金体”书法的宋徽宗喜欢墨又懂制墨，他亲自实践，推动了制墨业的发展。苏轼、陆游、黄庭坚等文人都有过参与制墨的经历。宣和三年（1121），歙州改成徽州，“徽墨”之名正式诞生，并代代相传，延续至今。 明代徽墨进入了发展的黄金时期。先进的桐油烟与漆油的制墨方法被广泛应用。徽墨普遍加入麝香、冰片、熊胆等十几种贵重原料，使墨的质地达到新的水平。竞争使徽墨在工艺进步的同时也提升了造型设计能力和墨模的雕刻技术。徽墨呈现出艺术品的潜质，也带动了从事艺术的文化人士投身工艺品创作的潮流。清代徽墨的发展虽不及明代的规模，但陆续出现了曹素功、胡开文等制墨名家。这一时期徽墨出现了集锦种类的墨，墨雕题材也更加丰富。墨雕题材多取自山川、建筑、风光、典籍、典故、儒家、道家、佛家等，少则几锭为一套，多则几十锭为一套，徽墨成为多种文化元素的载体。 由于社会动荡，近代徽墨的发展一度停滞，直至解放后制墨业才重新焕发生机。随着国家对传统文化的重视与保护，徽墨被列入了首批国家级非物质文化遗产名录。承载着厚重历史和传统艺术文化的徽墨也注意吸收时代元素，不断开发新的产品。在快速发展的时代背景下，徽墨如同由传统
