不合题意；B、因为水的比热容较大，升高相同的温度，水吸收的热量多，所以用水来冷却汽车发动机，故B 符合题意；C、水凝固成冰时，体积增大，是因为水结冰后质量不变、密度变小，所以体积增大，与水的比热容无关，故C 不合题意；D、水的沸点随气压的降低而降低，高原上，气压低，所以水的沸点降低，因此水温达到80℃ 可以沸腾，与水的比热容无关，故D 不合题意．故选B．【点评】本题考查了水的比热容大的特点的应用，应用所学知识，解释了实际问题，体现了新课标的要求，属于中考热点问题．6．（2 分）（2015•静安区二模）当物体放在凸透镜前，距焦点 20 厘米处，在透镜的另一侧离透镜 15 厘米的光屏上成像．该凸透镜的焦距（ ） A ．大于 20 厘米 B ．等于 20 厘米 C ．小于 15 厘米 D ．等于 15 厘米

比较出压强的变化，根据液体对各自容器底部的压强相等即可判断剩余液体对各自容器底部的压强变化，根据 F=pS 得出压力的大小关系．【解答】解：由于底面积不同的圆柱形容器分别盛有甲、乙两种液体时，液体对各自容器底 部的压强相等，即 p 甲 0=p 乙 0， 则：ρ甲 gh 甲=ρ乙gh 乙，由图可知：h 甲＞h 乙，则ρ甲＜ρ乙；在两容器中分别抽出相同高度△h 的液体，则两容器中液体对各自容器底部的压强减小量为： △p 甲=ρ甲g △h ，△p 乙=ρ乙g △h ， 所以，△p 甲＜△p 乙；由于剩余液体对各自容器底部的压强 p=p 0﹣△p ， 所以，p 甲＞p 乙．由压强公式p=可知：剩余液体对各自容器底部的压力F=pS，所以，F甲＞F乙．故选A．【点评】本题考查了学生对学生对压强公式、密度公式的掌握和运用，根据抽出相同高度△h 的液体利用p=ρgh 得出压强的减小量是本题的关键．8．（2分）（2015•静安区二模）在图所示的电路中，电源电压保持不变．闭合电键S后，当滑动变阻器的滑片向右移动时，在①、②、③、④各情况中，数据变大的有（）①电压表V 的示数②电流表A2的示数③电压表V 示数与电流表A 示数的比值④电流表A1示数与电流表A 示数的比值．A．只有①B．②和③

测干路电流，电流表A1测R1所在支路电流，电流表A2测滑动变阻器R2所在支路电流，电压表测量并联电路两端电压；因为电源电压不变，所以电压表的示数不变；当滑动变阻器的滑片P 向右移动时，滑动变阻器接入电路的阻值变大，并且电源电压不变，由欧姆定律可知，通过滑动变阻器R2支路的电流变小，通过R1支路的电流不变，即电流表A1的示数不变，电流表A2的示数变小；由于并联电路中，干路电流等于各支路电流之和，所以干路电流变小，即电流表A 的示数变小；因为电压表V 示数不变，电流表A 的示数变小，所以电压表V 示数与电流表A 示数的比值变大；因为电流表A1的示数不变，电流表A 的示数变小，所以电流表A1示数与电流表A 示数的比值变大．故选D．【点评】本题是一道闭合电路的动态分析题，难度较大，分析清楚电路结构、掌握滑动变阻器的用法、熟练应用欧姆定律、并联电路特点是正确解题的前提与关键．二、填空题（共23 分）9．（3 分）（2015•静安区二模）上海地区照明电路的电压为 220 伏；家中同时工作的用电器越多，电能表示数的变化越 多 （选填“少”或“多”）；标有“100W

求出所需要的时间．【解答】解：由图可求出，甲的速度 v 甲= = =0.1m/s ，乙的速度 v 乙= = =0.05m/s ．则甲、乙两物体的速度不同，如果以甲为参照物，则乙相对于甲的位置不断变化，乙是运动 的． 甲、乙、丙三小车同时同地向同一方向做匀速运动，当丙与甲、丙与乙的距离均为 0.3 米时， 由于甲、乙两物体的速度 v 甲＞v 乙，则丙一定在甲乙两物体之间，即 s 甲﹣s 丙=0.3m ，s 丙﹣v 乙=0.3m ，所以，s 甲﹣s 乙=0.3m+0.3m=0.6m ，即 v 甲t ﹣v 乙t=0.6m ，解得：t= ==12s ． 故答案为：运动；0.1；12．【点评】本题考查速度公式的应用和运动的情况判断；是一道图象分析题，图象可以直观地 反映出物理量间的关系，用图象描述物理量间的关系、反应物理规律是一种常用的方法，我 们要掌握识图、读图、作图的能力．12．（3

伏．当该导体两端的电压为6 伏后，该导体的电阻为10 欧．【考点】电量及其计算；欧姆定律的变形公式；电功计算公式的应用．【专题】电路和欧姆定律．【分析】已知电流和时间的大小，根据公式Q=It 可求通过导体的电荷量的大小；根据公式W=UQ 可求导体两端的电压；根据公式R=可求电阻的大小．【解答】解：由I=得，电荷量Q=It=0.3A×10s=3C；由I=、W=UIt 得：导体两端的电压为U== =3V；由I=得：R= = =10Ω；电阻与导体两端的电压无关；当它连接在电压为 6 伏的电源两端，该导体的电阻不变，还为10Ω．故答案为：3；3；10．【点评】本题考查电荷量、电压、电阻的计算，关键是公式及其变形的灵活运用，要知道电阻是导体本身的一种性质，它与导体两端的电压和通过导体的电流大小无关；灵活运用公式是解题的关键．14．（4分）（2015•静安区二模）在如图所示的电路中，电源电压保持不变．当电键S断开或闭合时，电压表V1、V2的示数始终相同，电路中只可能在电阻R、灯L 处发生故障．当电键S 闭合后．①若灯L 发光，则电路中的故障是电阻R 短路．②若灯L 不发光，则电路中的故障是灯L 断路或灯L 断路且电阻R 短路．【考点】电流表、电压表在判断电路故障中的应用．【专题】电路和欧姆定律．【分析】（1）根据电路图分析：灯和电阻串联，当电键S 断开或闭合时，电压表V1、V2的示数始终相同，若灯L 发光，则电阻R 短路；（2）由电路图分析：当电键S 断开或闭合时，电压表V1、V2的示数始终相同，若灯L 不发光，则灯L 断路或灯L 断路且电阻R 短路．【解答】解：①根据电路图分析：灯和电阻串联，当电键S 断开或闭合时，若灯L 发光，则电阻R 短路，会使得电压表V1、V2的示数始终相同，故故障为电阻R 短路；②由电路图分析：由于灯和电阻串联，当电键S 断开或闭合时，若灯L 不发光，则灯L 断路或灯L 断路且电阻R 短路，会使得电压表V1、V2的示数始终相同，故故障为灯L 断路或灯L 断路且电阻R 短路．故答案为：①电阻R 短路；②灯L 断路或灯L 断路且电阻R 短路．【点评】串联电路电流只有一条路径，用电器之间相互影响；注意分析电路，把握题目要求是解题关键．15．（4分）（2015•静安区二模）为了研究发生形变后的弹簧对其他物体做功的本领，小华同学选用不同弹簧A、B 和重物G 进行实验，弹簧A、B 原来的长度相等，一端固定，另一端与水平放置的重物G 相连，如图（a）所示．他们先后压缩弹簧A、B 并将其释放，弹簧释放过程中将重物G推动的距离为S（S1＜S2＜S3），如图（b）、（c）和（d）所示，图（c）、（d）中的弹簧A、B 压缩的程度相同．请仔细观察实验现象，归纳得出初步结论．①分析比较图（a）和（b）和（c）中弹簧的压缩程度、重物G 的移动距离以及相关条件，可得：同一弹簧形变程度越大，做功本领越强．②分析比较图（a）和（c）和（d）中弹簧的压缩程度、重物G 的移动距离以及相关条件，可得：原来长度相同的不同弹簧，形变程度相同时，做功本领不同．【考点】控制变量法与探究性实验方案．【专题】探究型实验综合题．【分析】（1）弹簧做功本领大小用物体的移动的距离来显示，物体移动距离越大，弹簧做功本领越强；（2）运用控制变量法，分析各组实验中弹簧、弹簧原长、形变程度的异同，结合重物移动的距离（即做功本领），得出结论．。

Being different from the art museum visitors, design museum visitors s 84 feel frightenedor puzzled. This is partly because design museums clearly show how and why mass-products(批量产品 )work and look as they do, and how design has i 85 our lives. People can see the better changes ofthe products . Art museum exhibits, on the other hand, would most probably fill visitors with a feelingthat there is something they don ’tunderstand.Several new design museums have opened their doors in recent years. Each of these museums has tried to satisfy the public’ s growingterestin in the field with new i 86 . London ’ s Design Museum, for example, shows a collection of mass-produced objects from electric typewriters to a group of Italianfish-tins.

Younger students may feel h 81in a home than in a hotel, for they can have someone caring for them like theirparents. Many British people like to be the “host”to tourists around the world,especially to f 82 students. This is not just because being a host will bringin some extra money, but because they really enjoy letting someone from adifferent country live in their house and s 83 part of their daily life.A “host”family does not always consist of two parents with children.People like this are often too busy to take care of a student b 84 their own children. However, a widow (寡妇 ), or a couple whose children are away at school or grown up, often make excellent “host”, for they have enough time to spare. Students should try to fit in with the everyday life of the family. There may be some d 85 and misunderstanding –on either side, but it is easy to clear them up quickly with good will and good humour. The secret of your success is to be interested.And a host tries to create more chances for the student to practice English. He always e 86 the student to speak English as much as possible in the home. He always does something to let the student feel at home and treat him/her as a member of the family, not a paying g 87 .

乙；F 甲＜F 乙C ．p 甲=p 乙；F 甲＞F 乙D ．p 甲=p 乙；F 甲＜F 乙【考点】压强大小比较；压力及重力与压力的区别．【专题】推理法；压强、液体的压强．【分析】由图知，液体对各自容器底部的压强相等和所盛液体的深度关系，根据压强公式p=ρgh 可得甲、乙两种液体的密度关系；在两容器中分别抽出相同高度△h 的液体，根据△p=ρg △h 比较出压强的变化，根据液体对各自容器底部的压强相等即可判断剩余液体对各自容器底部的压强变化，根据F=pS 得出压力的大小关系．【解答】解：由于底面积不同的圆柱形容器分别盛有甲、乙两种液体时，液体对各自容器底部的压强相等，即p 甲0=p 乙0，则：ρ甲gh 甲=ρ乙gh 乙，由图可知：h 甲＞h 乙，则ρ甲＜ρ乙；在两容器中分别抽出相同高度△h 的液体，则两容器中液体对各自容器底部的压强减小量为：△p 甲=ρ甲g △h ，△p 乙=ρ乙g △h ，所以，△p 甲＜△p 乙；由于剩余液体对各自容器底部的压强p=p 0﹣△p ，所以，p 甲＞p 乙．由压强公式p=可知：剩余液体对各自容器底部的压力F=pS，所以，F甲＞F乙．故选A．【点评】本题考查了学生对学生对压强公式、密度公式的掌握和运用，根据抽出相同高度△h的液体利用p=ρgh得出压强的减小量是本题的关键．8．（2分）（2015•静安区二模）在图所示的电路中，电源电压保持不变．闭合电键S后，当滑动变阻器的滑片向右移动时，在①、②、③、④各情况中，数据变大的有（）①电压表V的示数②电流表A2的示数③电压表V示数与电流表A示数的比值④电流表A1示数与电流表A示数的比值．A．只有①B．②和③C．只有③D．③和④【考点】电路的动态分析．【专题】电路变化分析综合题．【分析】分析清楚电路结构，根据滑片的移动方向判断滑动变阻器接入电路的阻值如何变化，然后根据欧姆定律、并联电路特点分析答题．【解答】解：由电路图可知，R1、R2并联，电流表A测干路电流，电流表A1测R1所在支路电流，电流表A2测滑动变阻器R2所在支路电流，电压表测量并联电路两端电压；因为电源电压不变，所以电压表的示数不变；当滑动变阻器的滑片P向右移动时，滑动变阻器接入电路的阻值变大，并且电源电压不变，由欧姆定律可知，通过滑动变阻器R2支路的电流变小，通过R1支路的电流不变，即电流表A1的示数不变，电流表A2的示数变小；由于并联电路中，干路电流等于各支路电流之和，所以干路电流变小，即电流表A的示数变小；因为电压表V示数不变，电流表A的示数变小，所以电压表V示数与电流表A示数的比值变大；因为电流表A1的示数不变，电流表A的示数变小，所以电流表A1示数与电流表A示数的比值变大．故选D．【点评】本题是一道闭合电路的动态分析题，难度较大，分析清楚电路结构、掌握滑动变阻器的用法、熟练应用欧姆定律、并联电路特点是正确解题的前提与关键．二、填空题（共23分）9．（3分）（2015•静安区二模）上海地区照明电路的电压为220伏；家中同时工作的用电器越多，电能表示数的变化越多（选填“少”或“多”）；标有“100W”字样的用电器正常工作5小时，消耗的电能为0.5千瓦•时．【考点】家庭电路工作电压、零线火线的辨别方法；电功的计算．【专题】电能和电功率．【分析】家庭电路的电压是220V．同时使用的用电器越多，其总功率越大，消耗电能越快．根据W=Pt计算灯泡正常工作5h消耗的电能．【解答】解：我国照明电路的电压为220V，上海地区也不例外；家中同时工作的用电器越多，总功率越大，根据W=Pt可知，相同时间内电能表示数的变化越多．标有“100W”字样的用电器，额定电压是220V，正常工作5小时，消耗的电能为：W=Pt=0.1kW×5h=0.5kW•h．故答案为：220；多；0.5．【点评】了解家庭电路的电压和工作特点，掌握家用电器铭牌上各参数的含义，可进行相关的计算．10．（3分）（2015•静安区二模）光从空气斜射到水面，当入射角为50°时，反射角为50°，在水中的折射角小于50°（选填“大于”或“小于”）．寒冬中互搓双手取暖，这是通过做功的方式来改变内能．【考点】光的反射定律；光的折射规律；做功改变物体内能．【专题】其他综合题．【分析】（1）光的反射定律：反射光线、入射光线、法线在同一个平面内，反射光线与入射光线分居法线两侧，反射角等于入射角；（2）光的折射定律：折射光线、入射光线、法线在同一个平面内，折射光线与入射光线分居法线两侧，光由空气斜射入水中时，折射光线向法线偏折，折射角小于入射角；（3）做功和热传递都能改变物体的内能．【解答】解：根据光的反射定律，反射角等于入射角，即反射角也为50°；根据折射定律可知，光由空气斜射入水中时，折射角小于入射角，因此折射角小于50°．双手用力对搓，手会感到暖和，属于做功改变内能．故答案为：50；小于；做功．【点评】此题查学生对基本概念和基本规律的识记能力，做对题的前提是熟记这些知识点，并灵活运用．11．（3分）（2015•静安区二模）水平地面上的甲、乙、丙三小车同时同地向同一方向做匀速运动，甲、乙的s﹣t图象，如图所示．行驶中，以甲为参照物，乙是运动的（选填“静止”或“运动”）；甲的速度为0.1米/秒；若在某运动时刻，丙与甲、丙与乙的距离均为0.1米，则在运动12秒时刻，丙与甲、丙与乙的距离均为0.3米．【考点】速度公式及其应用．【专题】计算题；运动和力．【分析】由图象判断出甲、乙的运动状态，求出它们的速度；根据甲、乙两物体的速度，判断以甲为参照物，乙相对于甲的位置变化，即可得出运动情况；根据甲、乙、丙三小车同时同地向同一方向做匀速运动，丙与甲、丙与乙的距离均为0.3米，首先判断出此时甲与乙之间的距离，然后利用s=vt求出所需要的时间．【解答】解：由图可求出，甲的速度v甲===0.1m/s，乙的速度v乙===0.05m/s．则甲、乙两物体的速度不同，如果以甲为参照物，则乙相对于甲的位置不断变化，乙是运动的．甲、乙、丙三小车同时同地向同一方向做匀速运动，当丙与甲、丙与乙的距离均为0.3米时，由于甲、乙两物体的速度v甲＞v乙，则丙一定在甲乙两物体之间，即s甲﹣s丙=0.3m，s丙﹣v乙=0.3m ，所以，s甲﹣s乙=0.3m+0.3m=0.6m，即v甲t﹣v乙t=0.6m，解得：t===12s．故答案为：运动；0.1；12．【点评】本题考查速度公式的应用和运动的情况判断；是一道图象分析题，图象可以直观地反映出物理量间的关系，用图象描述物理量间的关系、反应物理规律是一种常用的方法，我们要掌握识图、读图、作图的能力．12．（3分）（2015•静安区二模）如图所示，不计滑轮重及摩擦，物体A、B均重为20牛．当用力F2匀速提升物体B时，力F2为10牛；若物体A在10秒内匀速上升5米，力F1所做的功为100焦，其功率为10瓦．【考点】定滑轮及其工作特点；动滑轮及其工作特点；功的计算；功率的计算．【专题】机械与功．【分析】在不考虑动滑轮重、绳重和摩擦的条件下，使用定滑轮时不省力，即F=G物，使用动滑轮可以省一半力，即F=G物；不计滑轮重及摩擦，拉力F等于物体的重力G，根据W=Fs计算拉力所做的功；根据P=计算拉力的功率．【解答】解：因为滑轮组、绳重和摩擦均不计，所以：（1）物体B使用的是动滑轮，能省一半力，拉力F2=G=×20N=10N．（2）物体A使用的是定滑轮，不省力，拉力F1=G=20N，拉力所做的功W=F1s=20N×5m=100J，拉力的功率P===10W．故答案为：10；100；10．【点评】本题考查考查了对定滑轮和动滑轮工作特点、功和功率计算的理解与掌握情况，比较简单．13．（3分）（2015•静安区二模）通过某导体的电流为0.3安，10秒内通过该导体横截面的电荷量为3库，若这段时间内电流做功为9焦，则它两端的电压为3伏．当该导体两端的电压为6伏后，该导体的电阻为10欧．【考点】电量及其计算；欧姆定律的变形公式；电功计算公式的应用．【专题】电路和欧姆定律．【分析】已知电流和时间的大小，根据公式Q=It可求通过导体的电荷量的大小；根据公式W=UQ可求导体两端的电压；根据公式R=可求电阻的大小．【解答】解：由I=得，电荷量Q=It=0.3A×10s=3C；由I=、W=UIt得：导体两端的电压为U===3V；由I=得：R===10Ω；电阻与导体两端的电压无关；当它连接在电压为6伏的电源两端，该导体的电阻不变，还为10Ω．故答案为：3；3；10．【点评】本题考查电荷量、电压、电阻的计算，关键是公式及其变形的灵活运用，要知道电阻是导体本身的一种性质，它与导体两端的电压和通过导体的电流大小无关；灵活运用公式是解题的关键．14．（4分）（2015•静安区二模）在如图所示的电路中，电源电压保持不变．当电键S断开或闭合时，电压表V1、V2的示数始终相同，电路中只可能在电阻R、灯L处发生故障．当电键S闭合后．①若灯L发光，则电路中的故障是电阻R短路．。

Reading Comprehension (共50分)A. Choose the best answer (12分)Every country in the world has a flag. A flag is a piece of cloth with a picture or pattern on it. The flag is a symbol that stands for the country. It is a custom in many places for people to fly or hang a flag. The flag tells something about the country and its culture. This may be about its land, its history, or the things that the people do there.Many flags have patterns of stripes. The flag of Italy has a green stripe, a white stripe and a red stripe. Each stripe t ells something about Italy. The white stripe is symbol of Italy‘s snowy mountains. Some flags show pictures. The flag of Canada has a picture of a red maple leaf, which is a symbol of the maple trees in Canada. The Mexican flag has both a pattern of stripes and a picture. The picture shows an eagle eating a snake. This picture comes from a very old Mexican story.A flag may also tell about a country‘s past. The American flag is called the Stars and Stripes. It has pattern of fifty stars and thirteen stripes. The fifty stars are a symbol of the fifty states in the country, and the thirteen stripes are a symbol of the country‘s first thirteen colonies (殖民地).However, a flag may be a symbol of a group, a school, or an event like the Olympics. The flag of the Olympics shows five rings of different colors that connect. Each ring is a symbol for a part of the world that joins in the Olympics. The Red Cross is group that helps people who are in trouble. If a person sees the Red Cross flag, which has a red cross against a white background, he knows he can ask for help. People may fly a flag as a custom on a holiday. Children‘s Day in Japan is a holiday when the country wishes for children‘s happiness. It is a custom on this day to fly a flag with a picture of a fish.Flags are also used as a way to talk. A flag with patterns can be very helpful to people who do not speak the same language. Sailors on ships use flags to talk to sailors on other ships. They may not speak the same language, but they know what the patterns mean. A flag with blue and white squares says ―no.‖ A flag with five stripes thatare blue, white, and red says ―yes.‖69. We can usually see ______ on a flag.A) different languages B) a country‘s past C) a picture or pattern D) people70. Which of the following is the flag of Mexico?71. We can tell from the American flag that there are ______ states in the country.A) 1 B) 3 C) 13 D) 5072.

Choose the words or expressions and complete the passage（12分）I used to watch her from my kitchen window. She seemed so 75 as she muscled her way through the crowd of boys on the playground. The school was across the street from ourhome and I would often watch the kids as they played during break. I remember the first day I saw her playing basketball. I watched in wonder as she ran circles around the other kids. She managed to shoot jump shots just over their heads and into the net. The boys always tried to stop her but no one could. I began to notice her at other times, basketball in hand, playing alone.One day I asked her why she practiced so much. Without a moment of hesitation she said, "I want to go to college. The only way I can go is to get a scholarship (奖学金). I am going to play college basketball. I want to be the best. My daddy tells me 76 the dream is big enough, the facts don't count. "Well, I had to give it to her-She was determined. I watched her through those junior high years and into high school. Every week, she led her school team to 77 .One day in her senior year, I saw her sitting in the grass, head in her arms. I walked across the street and sat down in the cool grass beside her. 78 I asked what was wrong. "Oh, I am just not tall enough." came a soft reply. The coach told her that at 5'5" she would probably never get to play for a top ranked team-much less offered a scholarship -- so she should stop 79 college. She was heartbroken and I felt my own throat tighten as I sensed her disappointment. I asked her if she had talked to her dad about it yet. She told me that her father said those coaches were wrong. They just did not understand the power of a dream. He told her that if she truly wanted a scholarship and that nothing could stop her except one thing -- her own 80 .The next year, as she and her team went to the Northern California Championship game, she was offered a scholarship and on the college team. She was going to get the college education that she had looked forward to.75. A) beautiful B) crazy C) small D) responsible76. A) if B) although C) because D) unless77.

Over200,000 volunteers from more than 120 countries have applied to take a one-way trip to Mars.The project, run by a Dutch company named Mars One, aims to send a group of volunteersto Mars, and because of the physiological (生理上的) change in the human body after a styon Mars, there‘d be no chance of c81 back. So it‘s only a one-way trip! However, thathasn‘t stop volunteers becoming one of Mars‘ first citizens. ―This isrunning out to be the most welcome job in history,‖ says Ba sLansdorp, co-founder of Mars One.Day-to-day life on Mars will be not easy. The daily work will i 82building greenhouses or doing some research –all in a lonely environment.Mars is not f 83 to life. It‘s atmosphere is so thin that it won‘t protect you from harmful radiation from the sun. You can‘t breathe the air and it is very cold on Mars, with an average temperature of around -50°C. There‘s no running water on the surface ofMars. The water is frozen or hidden u 84 .But Mars One says the project is not looking for volunteers with some skill, such as a science degree.I 85 , they are looking for people who have ―a deep sense of purpose and responsibility‖. As the first group of people living on Mars, volunteers should be ―willing to build an d keep a healthy r 86 with the Earth‖. They also want volunteers who are ―curious, creative and good at finding ways of dealing with all kinds of problems.‖The volunteers will receive at least eight years‘ training b87 they leave Earth, the company says.
