2.答题卷与试卷在试题编号上是一一对应的,答题时应特别注意,不能够错位。

3.答题时间 150 分钟。

试卷满分 150 分。

4.一、阅读80分(一)阅读下文,完成1—— 6 题。

( 18 分)我们应该怎样流传经典王呈伟①文化经典之于国人不但象征了传统文化中的泰山北斗,更是民族一脉传承智慧的皇皇巨章;在老百姓眼里,那是读书人才能触摸到的高度,而自己无缘进学,只能算作殿堂外的旅人或侍从。

从这个意义上说,于丹的“说论语”使文化经典的阅读贴近了大众的生活,应该是文化普及中一次有价值的实践。

②其实历朝历代注《论语》,释儒学的学者可谓太多,但是他们所秉着的见解和解读的角度都是从对百姓的思想教化下手,以此来保护社会规范序次;文化经典的传承不能防备地带上了宣扬统治者见解的浓重色彩,成为特权意识或统治见解的载体。

当学者们蘸着时代的流行色去修饰原著的底色时,文化经典的意蕴就自但是然地打上了那个时代的思想烙印。

今天,就流传文化经典而言,摆在我们眼前的仍旧是怎样选择的问题,是继承秦汉以来的儒学,还是两宋此后的理学?抑或是上溯到先秦的儒家?③无论怎么说,今天的学者把历史的真实和版本的故事嫁接起来,运用现代高度发达的资讯传媒,让视听大众走近了传统文化的艺术殿堂。

但是学院派的学者大多坚守自己的学问准则,即使研究一辈子悟得其中一小部分,也只把这点心得变成大学课堂的讲义,不和老百姓搭界。

因此怎样把本民族的文化经典转播到老百姓能够拿来引用的层面,应该是这个时代的学人必定作答的问题。

④横向比较一下其他民族的经典文化流传会给我们一些启示。

他们的经典特别侧重把道理的深意融化成生活的小事,而事情的发生发展都尽量凑近大众的生活,让百姓在做的过程中不断感悟经典中蕴涵的道理。

(18分)我们应当怎样传播经典王呈伟①文化经典之于国人,不仅象征了传统文化中的泰山北斗,更是民族传承智慧的皇皇巨章。

在老百姓眼里,那是读书人才能触摸到的高度,而自己无缘进学,只能算作殿堂外的旅人或侍从。

从这个意义上说,于丹的“说论语”使文化经典的阅读贴近了大众的生活,应该是文化普及中一次有价值的实践。

②其实历朝历代注《论语》、释儒学的学者可谓太多,不过他们所秉持的观点和解读的角度都是从对百姓的思想教化入手,以此来维护社会规范秩序。

文化经典的传承不可避免地带上了宣扬统治者观点的浓重色彩,成为特权意识或统治观念的载体。

当学者们蘸着时代的流行色去润色原著的底色时,文化经典的意蕴就自然而然地打上了那个时代的思想烙印。

今天,就传播文化经典而言,摆在我们面前的依然是如何选择的问题:是继承汉以来的儒学,还是两宋之后的理学,抑或是上溯到先秦的儒家?③不管怎么说,今天的学者把历史的真实和演绎的故事嫁接起来,运用现代高度发达的资讯传媒,让视听大众走近了传统文化的艺术殿堂。

百家研读,百花齐放,有的结出些老百姓能吃的瓜果,有的只开些花儿让百姓看,有的只长刺甲批评家们像蜜蜂飞旋在花丛中,忙着采蜜,传粉,当然也有只会嗡嗡地叫来吸引人们视线的,春光乍现,一片喧闹而繁忙的景象。

不过学院派的学者大多坚守自己的学问准则,即使研究一辈子悟得其中的一小部分,也只把这点心得变成大学课堂的讲义,不和老百姓搭界。

因此如何把本民族的文化经典传播到老百姓可以拿来引用的层面,应该是这个时代的学人必须作答的问题。

(17分)前进到……自行车时代?①中国从自行车时代进入摩托车时代再进入汽车时代,有十几二十几年的过程。

现在正在把“有车”当作“成功人士”的标志。

这是跟在发达国家后面的前进和发展。

在电视剧中,高速路和立交桥上的钢铁甲虫群经常作为插入画面标志现代化社会的背景。

私家车普及之后,再进化呢?我们的思路一般是向着更快更高科技更值钱更豪华……升级的。

②那么,私家飞机吧?不大现实,发达国家好像还没有这个迹象。

③若仅从目前看有两种可能:有私家车人士越来越多;④过去没有想过第二种可能,因为那好像是逆现代化潮流而动。

但是一位最近到过荷兰的朋友说,荷兰的私家车已经明显少于美国了,现在他们那里是“满大街自行车”。

人们主要靠自行车和公交车代步。

也就是说,第二种可能如今不只是“可能”了——发达国家已经出现了这个迹象。

问题是,我们跟不跟?⑤最近读了一本《聚焦——来自一个正在变暖的世界的讯息》,美国资深气候专家马克·利纳斯全球旅行,到处寻找地球气候恶化的证据,以数字、文字和照片展示给世人看,因为这些讯息是“以一种几乎让人无法觉察的方式降临到地球上的”。

⑥英国洪水,美国飓风,这是新闻常常报道的。

在阿拉斯加,冻土融化,已造成大量建在冻土层上的房屋歪斜,门窗不能打开,不少房屋因下沉得无法居住而废弃。

即使勉强住着,人们也自嘲“小腿肌肉得到了锻炼”,因为家里的地板是倾斜的,“你总是在山坡上”。

以前由冻土支持的柏油路,路边的防护栏“扭曲成奇怪的形状,巨大的裂缝使得黑色的柏油路面四分五裂”,森林因为失去冻土层的支持,云杉东倒西歪,变成了“醉森林”。

而开采石油的企业和工人与绿色组织发生冲突,认为后者阻止油田开采是不让他们过好日子。

作家找到父亲年轻时在巴西利马附近拍摄常年不化的巨大冰川的原址,从原来角度拍下了一座基本裸露的山岩——冰川没有了。
