185s 4l 7118:57国开凿泾水，从中山以西一直到口修一条河渠，沿着北山向东注入洛水，长三百多里，可用河渠之水灌溉田地。秦国在凿渠中觉察到中了韩国的计谋，于是想杀掉郑国。郑国说：“我当初是间谍，但是渠凿成后对秦国也是有利的。”秦国认为郑国的话没错，于是命令继续凿渠。渠修成后，用渠中积蓄的水灌溉盐碱地四万多顷，每亩收成有一钟。于是关中成为肥沃之地,1/5没有灾害之年。秦国从此富强起来，最后吞并了诸侯各国。因此，秦国将参考答案 第1 页 (共5页)此渠命名为郑国渠。7．原句：始臣为间，然渠成亦秦之利也。大意：我当初是间谍，但是渠凿成后对秦国也是有利的。(找出句子2分，说出大意2分，共4分)二、文学之约（27分）8．sheng盛大、隆重（2分）9．示例：太行，美就美在神话传说。（2 分)10．D（2分)11．（1）示例一：我喜欢《红星照耀中国》中的毛泽东。他有冷静的政治头脑，是杰出的军事家和政治家，认真研究哲学，有相当深邃的情感,同时还精通中国旧学，是有成就的学者示例二：我喜欢《西游记》中的孙悟空。他上天入地，探妖洞、人魔窟，不辞辛劳、不畏艰险，敢于斗争、善于斗争，表现出非凡的智慧和无比的勇武，令我印象深刻。示例三：我喜欢《钢铁是怎样炼成的》中的保尔。他有着崇高的革命理想、顽强的生命力和忘我的献身精神，在全身瘫痪、双目失明的情况下,凭借顽强的毅力开始进行文学创作，影响了一代又一代的青年，也影响着我。（能准确说出名字1分，理由充分1分，共2分)（2）示例一：曾经，红星照亮了中国，开启了辉煌的时代；如今，红星依旧照耀着中国，激励我们继续奋斗。读一读埃德加·斯诺所著的《红国共产党领导的抗日根据地的真实情况，展示了中国的光明和希望。众多追求进步的青年受到感召，前往延安，参与到民族解放的洪流中。这本书一定会让你爱不释手的。示例二：中国古典四大名著之一《西游记》，由明代小说家吴承恩所著，是一部浪漫主义神魔小说。本书以丰富的想象力塑造了众多鲜明的人物形象，如孙悟空、猪八戒、沙僧和唐僧，展现了坚持、勇气和智慧的重要性。这不仅是一部娱乐性强的作品，还蕴含着深刻的思想内容。请阅读《西游记》，和师徒四人一起踏上奇幻的取经之旅，感受作者丰富的想象,参考答案 第2 页 (共5页)聆听一曲曲降妖伏魔、百折不挠的赞歌。示例三：我推荐《钢铁是怎样炼成的》。这是一部描写英雄成长历程的小说。人最宝贵的是生命，生命属于每个人只有一次，人的一生应当像保尔·柯察金那样去度过。一个人只有在革命的艰难困苦中战胜敌人也战胜自己，只有在把自己的追求和祖国、人民的利益联系在一起，才会创造出奇迹，才会成长为钢铁战士。相信保尔精神会成为你生命的航标灯。（能结合具体内容2分，语言流畅、富有表现力2分，共4分)12．（1）示例：第①处是母亲所述，表现了母亲不愿离开家乡，对故乡的依恋之情，同时呼应了文章的题目；第②处再次点题，总结全文，表（分别说出两句话的作用，各得2分；语言流畅1分，共5分。字数不足酌情扣分)（2）二例县亦圣垃地深深故园情城田的京士屑留不仕丹立
