（17分）重阳节启示：文化的生命传承顾晓鸣①国庆刚过，又临重阳。
重阳（农历九月初九），这由“九”和“九”两个阳数叠加而成的时日，谐音“久久”；这一天“登高”的习俗，又喻指着：人往高处走，一年的形成到了提升超越的时刻。
②在这样一个时刻，用心体会与传统佳节相连的中国文化中关于时间、生命和生活，以及个人、人生和社群的深邃智慧，有助于把外在的节日安排，转化为每个人、每个家庭、每个地区内在的节日持守（过节礼仪和习俗）；有助于通过“创旧”，创新出各种与相应佳节有关联的独特活动和文化产品；更可以明白传统佳节成为现代生活中法定节日的深远意义。
③传统佳节是人类社会文化特质的外显，在生命和历史的长河中，一个个时间节点被标记为民族的节日，以族人富有生命意蕴的节庆活动激活之，彰显之，流传之。
这是一个“文化记忆”的重要机制一一一是文字，而是仪式，而“节日”就在这两个方面，突出地镌刻着历史流程凝结而成的文化传统：“清明”、“端午”、“中秋”、“重阳”等等词汇，是那样的隽永醒目，结晶了丰富、动态、充满生机的文化意蕴；与之相连的节庆活动和礼仪以及食品、衣妆等，是生活过程中的“文化语言”，通过亲子的生命传递和行为习得，世事悠悠永流传。
这启示我们，当有了以这些传统节日标识的时间点之后，如何传承和创建相应的、能充分显示节日文化内涵的活动和礼仪，是一个课题。
④重阳节是“老人节”。
“老人”，是世界各民族文化中都有的“长者”或“长老”(Elders),这既是一个家庭中孩子的父（母）辈，血缘的祖先，更是一个社会的先人，代表着整个民族的智者，象征着文化传统的创造和传承的生命源头。

2012年各区一模压强压轴题含答案.
压强压轴题1. (12年宝山一模如图 14所示 , 两个底面积大小分别为 10厘米 2和 8厘米 2的薄壁圆柱形容器 A 和 B 放置在水平桌面上,已知 A 容器内部液体甲对容器底部产生的压强为 3136帕, B 容器内部盛的液体乙是水,且两容器中的液体液面高度均为 0.4米。
⑴求甲液体的密度ρ甲。
⑵求乙液体(水对 B 容器底部的压力 F 乙⑶若再从 A 、 B 两容器内同时抽出体积(ΔV容器底部的压强分别为 p´甲和 p ´乙 ,请通过计算比较它们的大小关系及其对应的ΔV 的取值范围。
2. (12年嘉定一模如图 11所示,质量为 0. 5千克,高为 0. 4米,底面积为 0. 01米 2的两个完全相同的薄壁柱形容器甲、乙放于水平桌面上,甲中盛有深度为 0. 2米的水,乙中盛有深度为 0. 15米,密度为 1. 8×103千克 /米 3的某种液体,求: (1 甲容器中水的质量。
(2 甲容器对水平桌面的压强。
(3 现在要使容器底部受到液体的压强相等,小明采用了正确的方法,在一个容器中倒入与原容器相同的液体, 在另一容器中倒出液体, 并且倒入和倒出液体的高度相同, 请你判断小明在容器甲中液体 (选填“ 倒入” 或“ 倒出” 。
求:倒入或倒出的高度。
图 14 A B图 113. (12年卢湾一模如图 10所示,圆柱形容器 A 和 B 放在水平地面上,它们的底面积分别为 2×10-2米 2和 1×10-2米 2。
A 容器中盛有 0. 2米高的水, B 容器中盛有 0. 3米高的酒精。
(ρ酒精=0. 8×103千克 /米 3求: ① A 容器中水对容器底部的压强 p 水。
② B 容器中酒精的质量 m 酒精。
③若在两容器中抽出相同质量的水和酒精后, 剩余液体对容器底部的压强分别为 p 水 '和 p 酒精 '。
请计算当 p 水 '>p 酒精 '时,抽出液体的质量范围。
2012年上海市宝山区中考物理一模试卷
2012年上海市宝山区中考物理一模试卷参考答案与试题解析试卷总分：90分一、选择题（共16分）下列各题均只有一个正确选项，请将正确选项的代号用2B铅笔填涂在答题纸的相应位置上，更改答案时，用橡皮擦去，重新填涂．1．（2分）（2011•宝山区一模）首先用实验测定大气压强值的科学家是（）A．托里拆利 B．阿基米德 C．库仑 D．帕斯卡【考点】大气压强PH238【难易度】容易题【分析】根据物理学常识来解答：A、1643年6月20日，意大利科学家托里拆利利用水银、长玻璃管、和水槽首先测出了标准大气压，A正确；B、古希腊的阿基米德是“力学之父”，发现并证明了杠杆定律和浮力定律（阿基米德原理），B错误；C、1785年法国物理学家库伦发现的电学发展使上的第一个定量规律，成为库伦定律，C错误；D、1653年帕斯卡提出了帕斯卡定律，论述了液体压强的传递问题，D错误。
【解答】A．【点评】本题主要考查考生对物理学史的掌握，是常识性问题，考生对于物理学上重大发现、发明、著名理论要加强记忆，清楚测定大气压强的实验原理。
2．（2分）（2011•宝山区一模）物体带负电是因为它（）A．得到电子 B．失去电子C．有多余的正电荷D．有多余负电荷【考点】分子和原子PH121【难易度】容易题【分析】物体是由分子组成的，分子是由原子组成的，原子是由原子核与核外电子组成的，原子核中的质子带正电荷，核外电子带负电荷，距离原子核越远的核外电子束缚力越弱，越容易发生电子的转移。
物体带负电是由于得到别的物体上的电子，有多余的负电荷，故选AD。
【解答】AD．【点评】解决本题考生需知道一般物体呈电中性，是由于原子核内质子数与核外电子数相等，当物体的核外电子发生转移，物体会带上负电或正电，同时知道物体得失电子取决于原子核对核外电子束缚能力的强弱。
3．（2分）（2011•宝山区一模）图所示的四个装置中不属于连通器的是（）A．船闸B．托里拆利实验C．茶壶D．牲畜饮水器【考点】连通器PH237【难易度】容易题【分析】上端开口不连通，下端连通的容器叫做连通器，连通器里的同一液体不流动时，各容器中直接与大气接触的液面总是保持同一高度。
