甘肃省天水市第一中学2018届高三第一次模拟考试 语文试题 学校_________ 班级__________ 姓名__________ 学号__________ 一、现代文阅读 1. 阅读下面的文字，完成下列小题。 康德认为，认识含有感性、知性和理性三个要素。感性是接受印象的能力，知性是规则的能力，理性是原理的能力，它们一起构成人类认识的完整结构。康德的这一划分，揭示了认识的基本层次，确立了理性的至高地位。西方的哲学思维方式本质上是理性主义，而中国传统哲学的思维方式却与其迥然而异：它无疑也含有理性主义的因素，但并不归结为理性主义；它较注重悟性、直觉和体验，但又不归结为非理性主义和直觉主义。它在本质上更具有“悟性”的色彩，是“悟性主义”。。 儒家的“格物致知”，通俗地说，就是用既有的思维尺度、框架去衡量、测度对象。只是这种把握绝非理性主义，它更具有“豁然贯通”的悟性特色。“季文子三思而后行。子闻之，曰：再，斯可矣。”由此可见，在孔子看来，如若过多地理性思考，结果可能适得其反，往往反致迷惑。老子的“玄览”，概括了道家的根本思维方式。“心居玄冥之处，览知万物”，从最超验的层次对事物的一种整体性的观照和透察。超验即要排除一切感性经验、语言概念和欲望，保持内心的清静和安宁。只有如此，才能做到“常无欲，以观其妙”。 中国佛教特别是禅宗是中印文化融合的产物，又吸收了儒家特别是道家的要素，凝聚了中国乃至东方悟性思维的精华。在佛家看来，“开悟”是修行之目的，而“菩提”为所悟之智，“涅”为所悟之理，佛及阿罗汉则为所开悟者。佛教义理对“悟”或“了悟”有甚为精密、详尽的研究和解说。依所悟之程度，将悟分为“小悟”和“大悟”；依所悟之迟速，将悟分为“渐悟”和“顿悟”；依所悟之途径，将悟分为“解悟”和“证悟”（由理解真理而知者为解悟，由实践修行而体得真理者为证悟）；依所悟之主体，将悟分为“悟自”和“悟他”，更为重要的是，佛教在长期的历史发展过程中，创造和积累了一整套系统而完备的了悟的方法，堪称无数佛教大师和佛教徒通过世代刻苦修行实践所取得的丰富的悟性体验的结晶。这种悟性主义的思维方式和思维特质尤其在中国禅宗中得到典型的充分的呈示。 中国传统哲学的悟性主义思维方式在儒家、道家和中国佛教特别是禅宗的悟性理论中体现得最为集中和鲜明。总体上说，以儒道释特别是中国禅宗为代表的中国传统哲学的悟性思维方式，完全超出了康德所划定的“感性、知性、悟性”的认识框架，超出了了康德将理性视为认识的最高形式的观点，从而也
