历届全国初中应用物理知识竞赛试题分类汇编—参考答案
运动和力一、选择题（2011）7C、原因：北斗星在北极上方，相对地球静止，北斗星在北极侧面，北斗星每一年绕北极星转1周，相当于地球每年绕太阳转一周，所以人们以北斗星的位置定位1年四季，不也就相当于以地球为参照物了么!（2007）2C、解：惯性，力不平衡；（2000）3 B；（2000）7 C；（2000）1 B；解：摩托车飞越高大障碍物时，若前轮先着地，前轮受地面的摩擦力使前轮的速度减小或静止，而摩托车的后轮及其他部分由于惯性还要继续向前运动，导致翻车；因此后轮先着地就可以避免翻车现象的发生．（1999）5A解：当三辆火车同方向，速度不同时，以速度处于中间的车为参照物时，看到另两列火车的关系就是向相反的方向运动，故A选项错误，B、C选项正确；当乘客坐在相对于地面静止的火车中，观察相对于地面向相反方向运动的另外两列火车时，会看到这两列火车向相反方向运动，故D选项正确．（1999）8A解：生鸡蛋的蛋液和蛋壳是两部分，转动时，蛋壳受力开始转动，蛋液由于惯性要保持原来静止的状态，从而给蛋壳一个阻力，所以很快就停下来；熟鸡蛋的蛋液和蛋壳是一个整体，转动时，蛋壳和蛋液都受力开始转动，转动的时间较长．（1994）1 C；（1992）13 B；(1991)2 D；(1991)6 D解：甲同学看到路边树木向东运动，是以他自己为参照物，说明他向西行走；乙看到甲静止不动，是以自己为参照物，他与甲同学之间的位置没有发生变化，说明他与甲同学以相同的速度，同向行走．二、填空题（2008）2解：由题知，客车的长度：L=11m×2.2×17=411.4m，经过的时间t=8s，小明相对于客车的速度：v=v1+v2=v1+108km/h=v1+30m/s，∵L=（v1+v2）t=（v1+30m/s）×8s，即：411.4m=（v1+30m/s）×8s，∴v1≈21.4m/s．故答案为：21.4．（2006）1解：由题意可知，小树、电线杆和村庄在一条直线上，村庄离车最远，所以相对于电线杆向后运动慢一点，人从车里往外看以电线杆为参照物时，村庄看上去是在往前运动；同理，可得出小树相对于电线杆向后运动．所以，村庄和小树绕着电线杆做顺时针转动．故答案为：前；后；顺．（2006）4解：如果轮胎有了磨损，轮半径减小，行驶相同的路程，车轮转动的圈数偏大，所以根据圈数测得的里程数和时速都要偏大；∵v=s/t，∴t=s/v，∵从北京到上海的路程知道（准确），速度表上指示的时速偏大，∴估算的时间比实际用的时间要小．故答案为：小于；小于．（2001）1解：下雨的方向相对于地面来说，雨是做平抛运动，平抛运动可分解为沿水平方向的匀速直线运动和沿竖直方向的自由落体运动，而此时的水平速度大小正好等于18km/h=5m/s，且方向也是由西向东，所以，此时该同学看到的是雨是成竖直状态下落，也就是雨相对于该同学是做自由落体运动了；故答案为：西，5．（2000）3解：虽然有风时雨是斜着下的，但是由于重力的作用，最终落入雨量筒的雨水的量是不受风向的影响的，所以有风的时候雨量筒竖立的方向不必变化，正确的使用方法为图（乙）所示，所以使用图中错误的方法即丙图，测得的雨量比实际降水量要多（因为落入雨量筒中的雨水多了）故正确答案为：乙，多．（1998）3解：由v=s/t得t=s/v=(L1+L2)/(v1+v2)答：两车从遇到离开所需时间为(L1+L2)/(v1+v2)．（1998）8解：当车向右开动时，水由于惯性要保持原来的静止状态，故水相对车向后运动，故会将气泡挤向右方；刹车时，水由于惯性要保持原来的运动状态，继续向前运动，所以会将气泡挤向左方；故答案为：右，左，水．（1997）5解：∵s=100米，t=9.86秒∴跑完100米的平均速度是v100=s100/t100=100米/9.86秒=10.1米/秒10米内平均速度最小的是v小=s10/t大=10米/1.88秒=9.2米/秒后20米的平均速度是v=s10/t小=(2×10米)/1.74秒=11.4米/秒10米内平均速度最大的是 v大=s10/t最小=10米/0.85秒=12.0米/秒＞11.4米/秒答：刘易斯这次百米赛跑的平均速度是10.1米/秒，他平均速度最小的是第一个10米，他的平均速度最大的是第八个10米．（1996）1解：汽车和汽车的像之间距离没有发生改变，方位没有发生改变，以汽车为参照物，汽车的像是静止的，相对速度为0．故答案为：0．（1996）8解：由题意可知甲比乙所走的路程多2个船距，即多走20m，s乙=v乙t乙=7m/s×80s=560m，所以，s甲=s乙+20m=560m+20m=580m，因此，v甲=s甲/t=580m/80s=7.25m/s．故填：7.25．（1993）2解：火车的速度v2=180km/h=50m/s，由公式s=vt得：列车鸣笛后3s时间内声音传播的路程为：s1=V1t=340m/s×3s=1020m；3s内列车前进的距离为：s2=V2t=50m/s×3s=150m；根据关系式：2s=s1+s2；列车鸣笛时距隧道口距离为：s=s1+s22=(1020m+150m)/2=585m．答：列车鸣笛时距隧道口距离为585m．(1991)1解：货物的质量：m=G/g=4.9N/(9.8N/kg)=0.5kg；过物体的重心作竖直向上的拉力和竖直向下的重力．如图所示(1991)3解：v=(N-1)L/t三、简答下列各题（2011）3、（1）①C所在部位。

2011年高考文综全国卷二含答案及解析
2011年普通高等学校招生全国统一考试文科综合能力测试（全国卷二）第I卷读图1.完成1~2题。
1.组成该山体岩石的矿物直接来自A．地表 B.地壳上部C.地壳下部D.地幔2.在岩石圈物质循环过程中，该山体岩石在地球表层可转化为A．喷出岩 B.侵入岩C．沉积岩 D.变质岩【解析】本组题难度中等，1题对大纲版而言，有超纲的嫌疑，因为大纲版未涉及地球内部圈层结构。
对课标版而言，则属于容易题。
1题、据图可知演示的是火山喷发，火山喷发物包括岩浆、碎屑物质和气体，这些物质均来自上地幔中的软流层。
2题、抓住“表层”和“转化”，岩浆岩可转化为沉积岩（地表）和变质岩（地下），这道题学生容易忽略“地球表层”而错选变质岩或者直接看成火山喷发物应该形成喷出岩。
芝加哥是美国五大湖区最大的城市，其位置见图2。
1848年修通联系密西西比河水系和五大湖的运河，随后兴建铁路并形成以芝加哥为中心的放射状铁路网。
这段时期，芝加哥工业主要有农产品加工、农具、交通工具等生产部门。
1890年，芝加哥人口达到100万。
20世纪上半叶，芝加哥发展以钢铁为主导的重工业，并成为20世纪美国最大的钢铁工业基地。
据此完成3~5题。
3．1848年后，芝加哥成为美国中西部农产品集散中心的主导区位条件是A．濒临五大湖B．位于美国中西部的中心位置C．位于密西西比河航运的上游起点D．位于密西西比河与五大湖的转运地点4.20世纪之前，芝加哥的工业活动主要联系A．芝加哥周边农村地区B．五大湖沿岸各城市C．美国东北部工业区D．美国本土5．芝加哥发展钢铁工业最有利的条件是A．良好的工业基础B．便捷的交通运输C．充足的劳动力D．丰富的原料和燃料【解析】本组题材料来自鲁教版教材，难度中等，主要考察学生提取、解读图文材料所显示信息的能力，答案基本都隐含在图文材料中。
3题、从材料中“1848年修通联系密西西比河水系和五大湖的运河，”得出早期以水运为主，结合图中显示的芝加哥的位置可推知芝加哥位于位于密西西比河与五大湖的转运地点。
MBA论证有效性分析真题及参考答案新
论证有效性分析历年真题【2012年1月】地球的气候变化已经成为当代世界的热点，这一问题看似复杂，其实简单，只要我们运用科学原理—如爱因斯坦的相对论一一去对待，也行就会找到解决这一问题的方法。
众所周知，爱因斯坦提出相对论颠覆了人类对于宇宙和自然地常识性观念，不管是狭义相对论还是广义相对论，都揭示了宇宙间事物运动中普遍存在的相对性。
既然宇宙万物的运动都是相对的，那么我们观察问题是也应该采用相对的方法，如变换视角等等。
假如我们变化视角去看一些问题，也学会得出和一般常识完全不同的观点，例如，我们称之为灾害的那些自然现象，包括海啸、台风、暴雨等等，其实也是大自然本身的一般现象而已，从大自然的视角来看，无所谓灾害不灾害，只是当它损害了人类利益，危机了人类生存的时候，从人类的视角来看，我们才称之为灾害。
再变换一下视角，从一个更广泛的范围来看，我们人类自己也是大自然的一部分，既然我们的祖先是类人猿，而类人猿正像大熊猫、华南虎、藏羚羊、扬子鳄乃至银杏、水杉等等一样，是珍格格自然生态中的有机组成部分，那为什么我们自己就不是了呢？由此可以，人类的问题就是大自然的问题，及时人类在某一时间部分的改变了气候，也还算整个大自然系统中的一个自然问题，自然问题自然会解决，人类不必过多干预。
（提示：论证有效性分析的一般要点是：概念特别是核心概念的界定和使用是否准确并前后一致，有无各种明显的逻辑错误，该论证的依据是否支持结论，论据成立的条件是否充分等。
要注意分析的内容深度、逻辑结构和语言表达。
）【参考答案】1、爱因斯坦相对论未必是颠覆了人类关于宇宙和自然常识性观念，或许也是一种补充，缺少依据。
2、万物间的运动未必都是相对的，即使是相对的，未必采用相对的方法就一定可行。
3、由自然灾害等来概括，来作证相对论有以偏概全之嫌。
4、人也是大自然中的一部分，也不足以证明不必干预自然，让其自然解决。
5、人类的问题都是大自然的问题过于绝对，或许轻率概括。

(2)在Rt △POH中, 22236xPH OP OH -=-=, ∴2362121x OH MH -==.在Rt △MPH 中,.∴y =GP=32MP=233631x +(0<x <6).(3)△PGH 是等腰三角形有三种可能情况:①GP=PH 时,xx =+233631,解得6=x . 经检验, 6=x 是原方程的根,且符合题意.②GP=GH 时, 2336312=+x ,解得0=x . 经检验, 0=x 是原方程的根,但不符合题意. ③PH=GH 时,2=x .综上所述,如果△PGH 是等腰三角形,那么线段PH 的长为6或2. 二、应用比例式建立函数解析式例2（2006年²山东）如图2,在△ABC 中,AB=AC=1,点D,E 在直线BC 上运动.设BD=,x CE=y .(1)如果∠BAC=30°,∠DAE=105°,试确定y 与x 之间的函数解析式；(2)如果∠BAC 的度数为α,∠DAE 的度数为β,当α,β满足怎样的关系式时,(1)中y 与x 之间的函数解析式还成立?试说明理由.解:(1)在△ABC 中,∵AB=AC,∠BAC=30°, ∴∠ABC=∠ACB=75°, ∴∠ABD=∠ACE=105°.∵∠BAC=30°,∠DAE=105°, ∴∠DAB+∠CAE=75°, 又∠DAB+∠ADB=∠ABC=75°, ∴∠CAE=∠ADB,∴△ADB ∽△EAC, ∴AC BD CE AB =,2222233621419x x x MH PH MP +=-+=+= A EDC B 图2HM NG POAB 图1xy∴11x y =, ∴x y 1=. (2)由于∠DAB+∠CAE=αβ-,又∠DAB+∠ADB=∠ABC=290α-︒,且函数关系式成立,∴290α-︒=αβ-, 整理得=-2αβ︒90.当=-2αβ︒90时,函数解析式x y 1=成立.例3(2005年²上海)如图3(1),在△ABC 中,∠ABC=90°,AB=4,BC=3. 点O 是边AC 上的一个动点,以点O 为圆心作半圆,与边AB 相切于点D,交线段OC 于点E.作EP ⊥ED,交射线AB 于点P,交射线CB 于点F. (1)求证: △ADE ∽△AEP. (2)设OA=x ,AP=y ,求y 关于x 的函数解析式,并写出它的定义域.(3)当BF=1时,求线段AP 的长. 解:(1)连结OD.根据题意,得OD ⊥AB,∴∠ODA=90°,∠ODA=∠DEP. 又由OD=OE,得∠ODE=∠OED.∴∠ADE=∠AEP, ∴△ADE ∽△AEP. (2)∵∠ABC=90°,AB=4,BC=3, ∴AC=5. ∵∠ABC=∠ADO=90°, ∴OD ∥BC, ∴53x OD =,54xAD =, ∴OD=x 53,AD=x 54. ∴AE=x x 53+=x58. ∵△ADE ∽△AEP, ∴AE AD APAE =, ∴x x yx 585458=. ∴x y 516= (8250≤<x ). (3)当BF=1时，①若EP 交线段CB 的延长线于点F,如图3(1)，则CF=4.∵∠ADE=∠AEP, ∴∠PDE=∠PEC. ∵∠FBP=∠DEP=90°, ∠FPB=∠DPE, ∴∠F=∠PDE, ∴∠F=∠FEC, ∴CF=CE.∴5-x 58=4,得85=x .可求得2=y ,即AP=2. ②若EP 交线段CB 于点F,如图3(2), 则CF=2.类似①,可得CF=CE.∴5-x 58=2,得815=x . 可求得6=y ,即AP=6.综上所述, 当BF=1时,线段AP 的长为2或6. 三、应用求图形面积的方法建立函数关系式例4（2004年²上海）如图,在△ABC 中,∠BAC=90°,AB=AC=22,⊙A 的半径为1.若点O 在● PD E A C B 3(2) O FO●FP DE A C B3(1) ABCO 图8HFABCE DBC 边上运动(与点B 、C 不重合),设BO=x ,△AOC 的面积为y . (1)求y 关于x 的函数解析式,并写出函数的定义域.(2)以点O 为圆心,BO 长为半径作圆O,求当⊙O 与⊙A 相切时, △AOC 的面积.解:(1)过点A 作AH ⊥BC,垂足为H.∵∠BAC=90°,AB=AC=22, ∴BC=4,AH=21BC=2. ∴OC=4-x .∵AHOC S AOC ⋅=∆21, ∴4+-=x y (40<<x ).(2)①当⊙O 与⊙A 外切时,在Rt △AOH 中,OA=1+x ,OH=x -2, ∴222)2(2)1(x x -+=+. 解得67=x .此时,△AOC 的面积y =617674=-. ②当⊙O 与⊙A 内切时,在Rt △AOH 中,OA=1-x ,OH=2-x , ∴222)2(2)1(-+=-x x . 解得27=x .此时,△AOC 的面积y =21274=-.综上所述,当⊙O 与⊙A 相切时,△AOC 的面积为617或21.专题二：动态几何型压轴题动态几何特点----问题背景是特殊图形，考查问题也是特殊图形，所以要把握好一般与特殊的关系；分析过程中，特别要关注图形的特性（特殊角、特殊图形的性质、图形的特殊位置。

It was walking along Park Road towards the east when an elderly man came out of the park on the other side of the street. Then I saw a yellow car drive up Third Street and make a right turn into Park Road. The next moment the car hit the man while he was crossing the road. He fell with a cry. The car didn't stop but drove off at great speed heading west. I noticed the driver was a young woman and the plate number was AC864. About two minutes later I stopped a passing car and took the old man to the nearest hospital.Li Hua2001年普通高等学校招生全国统一考试1．C 2 A 3．C 4．B 5．A 6．B 7．A 8． C 9．B 10．A11．B 12．C 13．B 14．A 15．C 16．A 17．B 18． A 19．C 20．B21．B 22．C 23．A 24，A 25．B 26.A 27．C 28．D 29，B 30．D 31．C 32．D 33．B 34．B 35，A 36．B 37．D 38．C 39．A 40．B 41．D 42．D 43．C 44A 45．B 46．C 47．B 48．D 49．B 50．C51．B 52．C 53．A 54．D 55．A 56．C 57．D 58．C 59．A 60．B 61．B 62．D 63．A 64．A 65．B 66．D 67．C 68．A 69．C 70．D 71．B 72．B 73．C 74．A 75．B第四部分第一节Like most of my schoolmates, I have neither brothers nor 76. ∨sisters - in any other words, I am an only child.

You want to know what is going on in schools in China? In short, things have begun to improve since schools were called on to reduce learning load. J don't know about others, but I used to have to work even at weekends doing endless homework and attending classes as well. Now I have more free time. I can follow my own interests such as reading books, visiting museums, and taking computer lessons. In the evenings I can watch news on TV or read newspapers. What's more, I can go to bed earlier. As far as I know, everyone is happy about this new arrangement of things.Best wishes,Li Hua2002年变通高等学校招生全国统一考试第一、二、三部分（key to 1-75）第四部分：CABBC BACBA CABCB CACBCBCDAD CBDAC ABCDBCABDA CDCAB DBCAD BCAADCBBD CBAA ADA DCBCB DACA第二卷第一节：Last week my parents and I took a two-day trip to EmeiMountain in Sichuan.

They believed a public park should be free of charge. People need a place where they can rest and enjoy themselves. Charging entrance fees will no doubt keep some people away. What is more, it will become necessary to build gates and walls, which will do harm to the appearance of a city. On the other hand, 40% think that fees should be charged because you need money to pay gardeners and other workers and to buy plants and young trees. They suggest, however, fees should be charged low.Yours truly,Li Hua2003年普通高等学校招生全国统一考试1-10 ABCBCCBACA 11-20 CABACBCABC 21-30 DBADDBCBCB 31-40 AADCACDCAD41-50 BADBCADBCA 51-60 CBADBACDDC 61-75 BCDCBBDABAADCDC76 √77 去掉in 78 everything 79 a 80 去掉should81 talking 82 myself 83 it 84 read 85 wordsDear Bob:I’m so glad to learn that you’re coming in September.
