  27页双基导航:一、填空题 1题:众数 2题:√S² 标准差 离散程度 3题:乙

  4题:8844 5题:31 ;46.5 6题:2 7题:-1 8题:(1)m-n (2)a-b

  (3) 3xy-3y² 9题:3;3 10题:1 11题:两条直线平行;他们同位角的平分线互相平行

  ;真 二、选择题 1~6 DDCBBD 三、可能产生增根的是D步

  四、计算并简化 (注意:/为分子与分母之间的分数线) 1题:原式=(15y-12x+6x)/12x²y²=(15y-6x)/12x²y² 2题:原式=(x+2)/(x+2)(x-2)—x/(x-2)

  =(x+2-x)/(x-2)=2/(x-2) 五、解方程 解:3(x-1)/x(x-1)=(x+5)/x(x-1)

  3x-3+6x=x+5 8x=8 x=1 检验:把x=1代人原方程中 出现了增根 ∴原方程无解

  六、(1)从上至下:13.2;13.4 (2)小明第二次成绩最好 ;小亮第四次成绩最好

  (3)他们的平均数都为13.3;小明的极差为0.2 小亮的极差为0.4:;小明的方差为0.004

  小亮的方差为0.02 建议:小明的成绩比较稳定 应该再突破;小亮的成绩不稳定,应该多

  锻炼 寻找原因 七、(1) ①平行四边形②(我实在没找出来怎么画图,非常抱歉)以CB

  为对称轴 画△CBD′对称于△CBD (2)找到AC的中点D 画DE‖CB 并让EB⊥CB

  则画出了矩形DCBE 八、(1)过N点做NH‖BC 交AE于G 则∠MHN=∠C=90°=∠B

  ∠NGO+∠ONG=90° ∠NAO+∠OGN=90° ∴∠NGO=∠NAO 又∵∠MHN=∠B NH=BC=AB

  ∴△ABE≌△MNH ∴AE=MN=10㎝ (2)解:∵∠A=40° AB=AC ∴∠ABC+∠C=140°

  ∠ABC=∠C=70° ∵AE=EB ∠AED=∠BED ED=ED ∴△AED≌△BED

  ∠EBD=∠A=40°∠DBC=70°—40°=30° ∠BDC=180°—70°—30°=80°

  70°≠30°≠80° 既BC≠DC≠BD ∴△BCD不是等腰三角形

1.医术高 为人正直 性子急 有正义感 有责任感
2.从结构上讲为下文的小故事埋伏笔做铺垫; 另一方面,也可以吸引读者的兴趣。
3.例如 小说开头这样写道 “他能把真牙修理得赛假牙一样漂亮,也能把假牙做得赛真牙一样得用” 点评 这样写 虽然有夸张的感觉,但却能生动直接地让人感受到或体会到 华大夫的高明医术。
4. 首先从构思来讲,文章先总而后分,开宗明义给读者介绍主人公的特点概况,而后有用具体事例来刻画描写人物 让读者 自己来判断体会人物的性格特点,最后再用旁观者角度进行综述和结尾 引人入胜。 从 情节来讲,小说的实例 可谓 环环相扣 ,不仅刻画人物到位,而且也能够 将读者吸引到具体情节中。

各位游客,一路辛苦了,欢迎您来趵突泉游园赏泉。
我们公园始建于一九五六年,因内有趵突泉而得名。现居市中心,位于泺源大街西首。趵突泉周围泉池众多,形成了趵突泉群。著名的金线泉、漱玉泉、马跑泉、卧牛泉、皇华泉、柳絮泉、老金线泉、洗钵泉、尚志泉、螺丝泉、满井泉、无忧泉、白云泉、望水泉、东高泉、登州泉、杜康泉、混沙泉、龙池泉、白龙湾等,构成了四大泉群之首。作为众泉之冠趵突泉成了泉城的独特象征。
我们趵突泉公园以观泉、赏鱼、品茶、山石、文化为特色,以小巧玲珑、步移景异,清洁幽静、古朴典雅而著称。全园共规划为十个景区,这就是趵突泉景区、三大殿景区、尚志堂景区、漱玉泉景区、东门入口区、枫溪景区、沧园景区、白雪楼区、南门入口区、万竹园景区,总面积近百亩。
趵突泉景区在我们公园内西侧,是全园构图中心,由亭、堂、廊、榭组成了一个封闭空间,高低错落的建筑像众星捧月一样,簇拥着喷突腾涌的趵突泉,人们可以从不同的角度欣赏泉景,被誉为泺水之源,在史书上第一次出现是<<春秋>>上关于鲁桓公和济襄公谈判两国边界一事的记载。鲁桓公十七年(公元前695年)。齐国和鲁国因边界争执发生战争,次年春,鲁桓公到齐国谈判边界问题,会齐侯(齐襄公)于泺。泺,泺水的源头,即趵突泉。所以趵突泉为人所知已经有二千五、六百年的历史了。当然那时泺水之源,名字并不叫趵突泉,北魏时,因泉上建有娥姜(英)庙,谷称娥姜(英)水,直到唐宋八大家之一的北宋文学家曾巩始称为趵突泉,并流传至今。不过,宋朝.金代曾有人称叫“温泉”、“槛泉”、“爆流泉”、“瀑流泉”等等,但都不如趵突泉这个名字精当传神。
趵突泉,三窟并发,声如隐雷,“泉源上奋”,“水涌若轮”称“趵突腾空“。“云雾润蒸”是趵突泉一景。泉水一年四季恒定在摄氏18度左右,到了严冬早晨,水面上水气袅袅上升,象一层薄烟,一边是泉池幽深,波光粼粼,一边是楼阁彩绘,雕梁画栋,这一切与淡淡的薄雾,构成一幅奇妙的人间仙境.奇特景观为济南八景之一,历代著名文学家、哲学家、诗人多有赞美。诸如宋代曾巩、苏轼、金代元好问,元代赵孟府、张养浩,明代王守仁,清代王士祯、蒲松龄、何绍基等都有吟泉佳作。康熙、乾隆皇帝都曾在趵突泉边写诗刻石,颂扬名泉,当代文豪郭沫若等也都有赞颂的美文。
趵突泉东西之间的这座南北向的小桥,名曰来鹤桥,原为木桥,明代万历初所建,天启末年重修,济南解放后扩建公园时将其改建为石桥。桥南首的彩绘木牌坊是原来的样子,牌坊匾额朝南的一面上刻“洞天福地”;朝北的一面是“蓬山旧迹”,“蓬山”指传说中东海神山的蓬莱、方丈、瀛州三座神山,趵突泉为何称“蓬山旧迹”?意为东海神山不过传说而已,谁也没有见过,但趵突泉的三股水其状如山,但不可攀,好象神话中的蓬莱仙山一般,所以称其为“蓬山旧迹”。泉池西侧伸入水中的小亭叫观澜亭,此亭建于明朝天顺五年(1461),至今已有500多年历史,亭西墙壁上嵌刻的两块石碑,一块“观澜”两个大字,取自<<孟子.尽心>>“观水有术,必观其澜”,为明代书法家张钦的墨迹。另一“第一泉”的石刻,是清朝同治年间王钟霖的手笔。亭东泉池中这块半浸水中的石碑,上镌三个雄健大字:趵突泉,为明代山东巡抚胡缵宗所写,细心的游客有的可能会发现突变成了“突”,缺了两点,传说劲挺柱涌的三股水把“盖子”顶掉了,才使“突”字变成了现在这个样子,当然这只是形容泉水势强,人们的一种遐想。泉池南岸透窗临池榭廊是解放后所建,近年来成了“闲时墨客会名优”京剧名流演出的舞台。趵突泉东池北岸,依水而著,窗明几净的建筑就是有名的蓬莱茶社,又称望鹤亭茶社,清代文人施闰章曾写诗歌曰:“仰而见山之青,俯而见泉之洁,清流激湍兮,孰浚其源?潜蛟出蛰兮,飞虹蜿蜒”。说明这个地方在当时是极目远眺,俯首凝视,观赏领略远近山水之美的绝妙境地。据说当年康熙、乾隆两个皇帝都曾在这里临水静坐,品茗赏泉,领略趵突泉的万般风韵。当品尝到趵突泉水后,竟将南巡中携饮之北京玉泉水全部换为趵突泉的水,故有“润泽春茶味更真”,不饮趵突泉的水,空负济南游之说。趵突泉池北岸的大殿叫“泺源堂”,紧挨泺源堂的两座大殿,统称吕祖庙,也叫“吕仙祠”、“吕公祠”、“吕祖阁”。
