高二上学期期末试卷2(附答案)

高二上语文期末试题 一、现代文阅读(9分) 阅读下面的文字,完成1——3题。 2007年11月,良渚文化核心区域发现一座古城遗址——良渚古城。考古学界测定,良渚文化时期距今约5300—4000年,处于新石器时代晚期,尧舜禹时代早期。这个时期由于没有确切的史料留存于世,我们所知道的关于良渚文化的一鳞半爪,都是来自先前出土的文物。专家认为良渚古城发现的意义不亚于殷墟的发现,因为长江中下游地区之前还从未发现良渚文化时期的城址,它是目前所发现的同时代中国最大的古城遗址,作为实证中华5000年文明史的最具规模和水平的地区之一,良渚古城的发现,有助于厘清史料中没有记载的夏商周之前的那段历史。 古城的南北都是天目山脉的支脉,城与山的距离大致相等,苕溪和良渚港分别由城的南北两侧流过,两个自然的小山,分别位于城墙的西南角和东北角。城墙的底部铺垫的石头都很尖锐,由人工开凿而成。上部用较纯净的黄土一部分一部分夯筑而成,黄土不同于良渚一带灰黑色淤泥,应是人工从外面搬运而来。古城面积约有29万平方米,与颐和园相当,而颐和园四分之三的为水域。如此浩大的工程其石料量、土方量及工匠数量可想而知。明代修建的故宫占地只有72万多平方米,却也要役使百万夫役,也历经14年时间。 在良渚文化的墓葬中,发现了琮、璧、钺等玉器,琮是一种用来祭祀大地的礼器,形状外方内圆,象征着天地的贯穿。对良渚人来说琮是象征王权神权的法器。璧发现的数量众多,其像天园的形状表示它是祭天的礼器,但众多的更像是一种财富的象征。关于钺《说文解字》说它是从斧发展而来的砍伐或打仗用的武器。研究表明,琮、璧的形状和刻纹最早出现在良渚文化时期,而钺在良渚文化时期早期已完成了由石钺到玉钺的转变。钺由石质变成了玉质,功能应该已转化,可能转化成了军权的象征。 关于古代用玉的等级制度做了记载:《周礼·冬官》称:“天子用全,上公用龙,侯用瓒,伯用将。”郑玄注:“全,纯色也;龙、瓒、将,皆杂色也。在城内反山大墓中出土的玉器均为真玉中的透闪石软玉;规模稍次一级的上海福泉山九号墓出土的玉器,则真玉居多而杂有假玉;而较一般的浙江海宁荷叶地则真假玉参半。由此可以推断,良渚古城应该是处于当时最高阶层居住的地方,良渚文化已经基本形成用玉的等级制度,被称为夏商周“三代之礼一”的用玉等级制度完全可以上溯到良渚文化时代。 在良渚出土的黑陶器上发现过不少的刻划符号,这些刻划符号都表达了一定的内涵,已经具有文字的性质,在文字的发展历程中,应当处于从原始记事符号到文字产生之间的过渡阶段,是初期象形文字,在后世的甲骨文中能看到它的影子。专家指出,文字是人类思想成熟的表现,只有在社会长期持续、稳定发展,社会结构完善、统一的基础上,才能为文字的出现营造一个良好的发展环境。 1、下列不能作为“良渚古城发现的意义不亚于殷墟的发现”这一论断依据的一项是(3分) () A、长江中下游地区之前还从未发现良渚文化时期的城址。 B、有助于厘清史料中没有记载的夏商周之前的那段历史。 C、可以进一步了解良渚文化时代的等级制度和社会结构。 D、使原先一鳞半爪的文字发展历程的研究变得完整全面。 2、下列最能体现良渚古城建筑特点的一项是(3分)() A、古城筑于天目山脉的支脉,城的南北两侧有苕溪和良渚港流过。
