一、本大题共10小题，共31分。

阅读下面的文字，按要求完成1-10题。

【材料一】中药命名的文化意蕴?厚朴?是一味中药。

中医药书称其因?本质朴而皮厚?得名。

但这看似简单的药名却实在不简单。

厚，是淳厚的厚；朴，是质朴的朴。

淳厚与质朴是中国人一向赞美的品德，巧妙地落在了一味药草上。

在数千种中草药中，有很多这样粗看自然质朴，细品却韵味十足的药名。

“百合”的意趣医圣张仲景的经典著作《金匮要略》中记录了这样一种病：患病者精神、饮食、行动皆异于常人，沉默少言，欲睡难眠，不思饮食，此为?百合病？。

中医认为这个病多由心神失养，或情致不调等引起。

治疗这个病常用?百合?为主药，以百合地黄汤为主方，在此基础上再根据病情及时调整。

那么，?百合?究竟是什么样子呢？说来没什么稀奇，罗大佑歌中的?野百合?和近年被阿宝唱响的?山丹丹?就是这味百合良药。

娇艳的百合花在山野蓬蒿．中亭亭玉立，其生于地下的鳞茎由近百块鳞瓣抱合而成，古人将其视为?百年好合?的吉兆，花也因此得名。

不过，治疗百合病的不是美丽的花朵，而是那抱合的鳞茎。

百合具有滋阴润肺、镇静安神之功效，在中医看来，精神、情绪上的问题，就要用?百合?去治。

因此，就有了百合病是?因以百合为主药才得名?的说法，百合也有了?因治百合病才叫百合?的另一种得名原因。

中草药中，像百合一样拥有美妙、独特的名字的还有很多。

比如《神农本草经》一书中将一种主治时疾寒热、内补不足的?玉竹?列为上品，但此草并非竹类，它还有个名字叫?葳蕤．．?，有华美之意。

不过，?玉竹?之名更雅。

李时珍说?其叶光莹像竹，其根长而多节？，故名玉竹。

药名的诗情比起西药以化学分析为起点命名的科学和理性，中药本草的命名则大都感性。

有的药名本身就极富诗意，成为可以寄喻．情思的对象。

2015年上海普陀区高三二模英语试卷-学生用卷一、语法填空1、【来源】 2015年上海普陀区高三二模第1题AGood ideas often start with really silly questions. Bill Bowerman was making breakfast one day. As he stood there making waffles (华夫饼干) for his son, he wondered what would happen if he poured rubber 1 his waffle iron. Later, he tried it and the result looked something like the bottom of most sports shoes we see today. Still, when he took this idea to several existing shoe companies, he was laughed at. In fact, every single company turned him down. Though rather discouraged, Bowerman persevered and went on 2(form) his own company, making NIKE athletic shoes.Sometimes good ideas grow out of frustration. When Fred Smith was a student at Yale University, he needed to have some paperwork 3(deliver) across the country the next day. Smith was amazed to find out that overnight delivery was impossible. He sat for a longwhile 4 (wonder) why. Why couldn’t there be a reliable overnight mail delivery service? He decided to design one. Smith did just that and turned his designinto 5class project. His business professor gave him only a C for his efforts. However, Smith was not through. He improved the ideas in that class project and eventuallyturned 6 into one of the first and 7(successful) overnight mail services in the world—FedEx.We know today, of course, that each of these ideas led to an incredibly successful product or service 8has changed the way many of us live. The best questions are usually open-ended and are often silly. Children aren’t afraid to ask such questions, but adults frequently are. Think how different the world might be9 people never asked “silly”question!2、【来源】 2015年上海普陀区高三二模第2题BA lot of people in the world today are used to working, going on holiday, and having money—but many of them aren’t happy. Yet other people seem to be really happy,1they are poor, or have no job, or are surrounded by problems. Why?Professor Mihaly Csikszentmihalyi, from the University of Chicago, has interviewed thousands of people who have a happy life to find out how they do it. “I 2(study) happiness for over 30 years,” says Csikszentmihalyi. “My interest in the subject came from my own experience as a child during World War II, when I saw many adults destroyed by the terrible events. But there were always a few who kept their courage, helped others, and were able to give a sense of purpose and meaning to their lives. I wanted to find out how a person 3 build a fulfilling and enjoyable life.”In general, his research showed that people were unhappy doing nothing. The professor stresses that happy people don’t waste time, either at work or when they’re free. “Many people feel the time that they spend at work or at school wasted. But often their free time 4 (waste) as well. Many people are used to doing passive things—watching television, for example—without 5 (use) any skills. As a result, life goes past in a series of boring experiences.”But it doesn’t have to be this way. The professor has found that people are happy when they get into 6he calls “flow”. When people get very involved in a task that they have chosen, and which is well-defined and challenging, they experience “flow”, asituation7they don’t notice time passing.People who are not used to happiness can learn how to be happy, says the professor, if they constantly get into “flow” states. Is happiness as easy as that? Perhaps it is.二、选词填空3、【来源】 2015年上海普陀区高三二模第3题The world faces a future of people speaking more than one language, with English no longer seen as likely to become1, a British language expert says in a new analysis. "English is likely to2one of the world's most important languages for the foreseeable future, but its future is more3and complex—than most people appreciate, " language researcher David Graddol said. He sees English as likely to become the "first among equals" rather than having the global field to itself.

On one hand, some farmers and scientists feel that GM crops can make the world a1place. If bioengineers can create crops that are resistant to insects,2, then they won't have to worry about insects destroying plants. In the3of insect damage, crops can grow to feed the poor and hungry. Genetic engineering can create plants with other desirable properties as well. Plants that don't require much water, that can live even in times of drought, can help prevent thewidespread4that would occur if people have nothing to eat. It's easy to seewhy many people believe that GM crops will help the world meet thedifficult5that it will face as more and more people need to be fed.But not everyone thinks bioengineering is a good idea.

The possible dangers include harming the ecosystem—the inter-related community of plants and animals and bacteria that8the Earth.They9that changing plants can harm our environment, and damage to our surroundings can hurt us. One danger is that GM crops can transfer their characteristics to other plants.

This fantastic control center lets you think, learn, create, and feel emotions. It also controls everything your body does. What is this amazing machine? It's your brain—a structure so amazing that the famous scientist James Watson called it "the most complex thing we have yet discovered in our universe."Imagine your kitten jumped onto the kitchen counter, and was about to step onto a hot stove. You would have only seconds to act. In situations like this, your brain reads the signals from your eyes and quickly calculates when, where and at what speed you need to run to save her. Then it tells your muscles to move. No computer can match your brain's great ability to download, process, and react to the flood of information from your eyes, ears and other sensory organs.If a bee lands on your foot, sensory neurons（神经元） in your skin send this information to your brain at a speed of more than 240 kilometers per hour. Your brain then uses motor neurons to send a message back to your foot: Shake the bee off quickly! Motor neurons can send this information at more than 320 kilometers per hour!Your brain contains about 100 billion tiny cells: neurons—it would take you more than 3, 000 years if you tried to count them all. Whenever you dream, laugh, think, see or move, tiny chemical and electrical signals are racing between these neurons along billions of tiny neuron pathways. Believe it or not, the activity in your brain never stops. Countless messages fly around inside it every second, like a super-fast game of table tennis. Your neurons create and send more messages than all the phones in the entire world. And although a single neuron generates only a tiny amount of electricity, all your neurons together can generate enough electricity to power a light bulb.(1) By "the most complex thing" , James Watson means.A. a supercomputerB. the universeC. human brainsD. our emotions(2) Which of the following statements is true according to the 2nd and 3rd paragraph?A. Brains can download more information than any computer.B. The kitten plays an important role in testing human brain power.C. Motor neurons in human brains serve to send countless messages.D. Your brains can use neurons to send messages back faster than bees’.(3) The author mentions "to power light bulbs" （Para. 4） to show.A. neurons can send lots of messagesB. how many active tiny cells brains containC. how much electricity brains can generateD. there is countless information in the brain(4) What is the main idea of the passage?A. Powerful brain is a wonderful machine.B. Brains work well in controlling body movements.C. Brain is the most complex structure in the universe.D. Human brains are composed of numerous neurons.6、【来源】 2015年上海普陀区高三二模（B篇）第6~8题Read the following car rental agreement of Avis and answer the questions.Kindly indicate your return km reading, fuel gauge（计量器） reading, date and time, and return this envelope, with your keys, to the rental counter.Document numberSafe Drivingin South AfricaDRIVER'S LICENCEWhen driving, you must be in possession of your driver's licence at all times.SEAT BELTSThe law requires that you wear seat belts at all times.DRIVINGIn South Africa, driving is on the left-hand side of the road.SPEED LIMITSGenerally 60 km/hr in built-up areas, 100 km/hr in rural areas and 120 km/hr on highways.PETROLPetrol is available 24 hours per day.

Never before have we seen people working together who represent such different backgrounds and experiences. This difference of age, race, gender, and work style makes it very difficult to organize and run a company.As a result, companies are looking for individuals who can manage a wide range of employees effectively. Increasingly, managers are discovering that age differences among workers are a major cause of concern.This has been an important realization. The management difficulties and challenges have led some experts to study intergenerational differences for an understanding of problems in the workplace. What they have discovered is interesting and may provide ways of improving working conditions in companies that employ individuals from different generations.The first thing to realize, they say, is that differences of opinion about the importance of work and how to get work done are not a coincidence. That is, it is not an accident that young employees will be different from older employees. In fact, if employers do not pay attention to these differences, it is possible that anger will build up between people and lead to difficulties in the company.Resentment （仇恨） between members of different generations, if not attended to, can lead to extreme anger and unhappiness and even lasting enmity if people are not careful. That individuals from different generations should come to view each other as if they were from different sides of warring countries should not be surprising.It is natural for individuals from the same generation to form alliances （联盟）, to come together for protection. Different generations represent different experiences in life, and these lead naturally to different opinions about oneself and one's approaches to work.If you were raised in a time of plenty, when products were readily available and relatively inexpensive, you would believe that prosperity is natural and expectable. If, on the other hand, you were raised in a time of scarcity, you would always be careful not to waste things for fear you would not have enough. You would make angry people who seem to believe that problems will always solve themselves. Such optimism in the face of difficulties would be a source of unhappiness between you and them. It is difficult, in such circumstances, to achieve a happy, agreeable atmosphere in the workplace.(1) What most possibly makes it difficult to organize or run a company?A. Employees are in different generations.B. Employees are of different backgrounds.C. Employees work in different styles.D. Employees are in different races.(2) Employers should pay attention to if they want to avoid anger between employees.A. the different understanding of problems in the workplaceB. the different views on value of work and working methodsC. the different generations of employees in the workplaceD. the different ways of expressing anger in the company(3) The word "enmity" is closet in meaning to.A. hatredB. sorrowsC. ignoranceD. forgiveness(4) What can be inferred from the passage?A. Employees in some companies regard each other as mere enemies.B. Employees' attitudes towards life are related to the time when they grow up.C. Employees who are raised in a time of scarcity tend to be angry with others.D. Achieving a harmonious atmosphere in the workplace is the main task for employers.(5) What does the writer mainly talk about in the passage?A. Employees should be cooperative and friendly with each other.B. It is difficult for employers to have workers work in a friendly way.C. The weakness of human nature causes the anger between employees.D. The generational differences cause the disharmony among employees.五、任务型阅读8、【来源】 2015年上海普陀区高三二模第8~11题Dolphins have been declared the world's second most intelligent creatures after humans, with scientists suggesting they are so bright that they should be treated as "non-human persons" .Studies into dolphin behavior have highlighted how similar their communications are to those of humans and that they are brighter than chimpanzees. These have been backed up by anatomical （解剖学） research showing that dolphin brains have many key features associated with high intelligence. Recently, a series of behavioral studies has suggested that dolphins, especially species such as the bottlenose, whose brains weigh about 5lb, could even be brighter than chimps, which some studies have found can reach the intelligence levels of three-year-old children. The studies show how dolphins have distinct personalities, a strong sense of self and can think about the future.It has also become clear that dolphins are "culture" animals, meaning that new types of behavior can quickly be picked up by one dolphin from another. In one study, Diana Reiss, professor of psychology at Hunter College, City University of New York, showed that bottlenose dolphins could recognize themselves in a mirror and use it to inspect various parts of their bodies, an ability that had been thought limited to humans and great apes. In another, she found that they also had the ability to learn an elementary symbol-based language.Other research has shown dolphins can solve difficult problems, while those living in the wild cooperate in ways that imply complex social structures and a high level of emotions. In one recent case, a dolphin rescued from the wild was taught to tail-walk for three weeks in a dolphinarium （海豚宫） in Australia. After she was released, scientists were astonished to see the trick spreading among wild dolphinswho had learnt it from the former captive （被俘的）. Such observations have prompted questions about the brain structures of dolphins.Researchers have found that brain size varies hugely from around 7oz for the small species to more than 19lb for the sperm whales, whose brains are the largest on the planet. Human brains, by contrast, range from 21lb-4lb. When it comes to intelligence, however, brain size is less important than its size relative to the body.oz: an ounce in weight （1oz=28g）lb: a pound in weight （1lb=454g=16oz）（Note: Answer the questions or complete the statements in no more than twelve words.）(1) The which in the 2nd paragraph refers to.(2) What do bottlenose dolphins do to make Diana Reiss believe they are "culture" animals?(3) The spreading of tail-walk shows wild dolphins have.(4) What is the main factor that decides the level of intelligence according to the last paragraph?六、翻译9、【来源】 2015年上海普陀区高三二模第9题翻译(1) 学校里约半数的学生热衷于玩手机游戏。

（17分）经典谁说了算王乾坤①很难说我们所处的是一个“去经典”还是“趋经典”的时代。

有一点可以肯定，这是一个不太吝啬“经典”名词的时代。

那么，什么是经典？经典由谁说了算？②通常的回答是：权威说了算或大众说了算。

但深通艺术之堂奥的人既不看重权势的眼色，也不在意大众的褒贬，他们心里明白：权威认定、大众评判也许不可或缺，但一切有形的人为裁判只有在文学合法性的前提下，才可能是有效的。

换言之，他们在乎的或敬畏的，是文学本身的法权。

③文学的自然法不是任何一种成文的文学法则，而是一种无形的天则。

“俯察人事，仰观天则。

”人事俯身可察，天则是需要仰观的。

由“自然法”来言事物的合法性本是天经地义。

可是在文明史上，天经地义的天则被各种偏见所干扰反倒成了常态。

五花八门的政治观、道德观、科学观、文化观、历史观以种种集体偶像的强势向文学越权，任意在这个领域封号经典，成了由来已久的“常态”。

④现当代，影响文学创作和评论的有两种思潮：一是认为世界是按照优胜劣汰的进化论定律演进的，二是认为权力可以决定一切。

这两种思潮交合成一种集体无意识：优胜在于权力，劣汰在于无权力。

于是，话语权如拜物教一般左右着创作家和评论家，从事文学艺术的匠人们使出浑身解数，不顾一切地调动可能的权力让自己的声音足够强大，最好是压倒一切成为中心。

⑤可惜，话语权或其他权力决定论不能解释中外文学的经典史，只要检索一些古今中外文学巨匠们弱势的社会身份或话语权状况就能验证。

⑥那么进入文苑的小说多得是，为什么能被认定经典的是此而不是彼？是谁在进行这种无形的筛选？答案只能在文学合法性中寻求。

2015北京市西城高三（二模）物理13．下列关于光的本性的说法正确的是（）A．光电效应现象说明光具有粒子性B．光电效应现象说明光具有波动性C．光的干涉、衍射现象说明光是横波D．光的干涉、衍射现象说明光是纵波14．一列沿x轴正方向传播的简谐横波，在某一时刻的波形曲线如图所示，由图可知（）A．各质点振动的周期为4s B．该简谐横波的波长为4mC．此时刻质点A的速度为0

D．N＜mg，T＜mg16．如图所示，虚线为电场中的三个等势面，相邻等势面之间的电势差相等．一个带正电的点电荷在A点的电势能大于其在B点的电势能，则下列说法正确的是（）A．A点的电势比B点的高B．无法比较A、B两点的电势高低C．A点的电场强度比B点的大D．无法比较A、B两点的场强大小17．在如图所示的电路中，L1、L2是两个相同的小灯泡，A、B处的虚线框内各接有一个电学元件．a、b两端分别与直流电源和交流电源相连接，且直流电源的电压与交流电源电压的有效值相等．观察两种情况下灯泡的亮度．当接直流电源时，L1不发光，L2正常发光；当接交流电源时，L1发光，L2明显变暗．则下列说法正确的是（）A．A中接的是电阻，B中接的是电容器B．A中接的是电感线圈，B中接的是电阻C．A中接的是电感线圈，B中接的是电容器D．A中接的是电容器，B中接的是电感线圈18．如图所示为游乐场中过山车的一段轨道，P点是这段轨道的最高点，A、B、C三处是过山车的车头、中点和车尾．假设这段轨道是圆轨道，各节车厢的质量相等，过山车在运行过程中不受牵引力，所受阻力可忽略．那么，过山车在通过P点的过程中，下列说法正确的是（）A．车头A通过P点时的速度最小B．车的中点B通过P点时的速度最小C．车尾C通过P点时的速度最小D．A、B、C通过P点时的速度一样大19．如图是一个多用电表的简化电路图．S为单刀多掷开关，通过操作开关，接线柱O可以接通1，也可以接通2、3、4、5或6．下列说法正确的是（）A．当开关S分别接1或2时，测量的是电流，其中S接1时量程较大B．当开关S分别接3或4时，测量的是电阻，其中A是黑表笔C．当开关S分别接5或6时，测量的是电阻，其中A是红表笔D．当开关S分别接5和6时，测量的是电压，其中S接5时量程较大20．由于分子间存在着分子力，而分子力做功与路径无关，因此分子间存在与其相对距离有关的分子势能．如图所示为分子势能E p随分子间距离r变化的图象，取r趋近于无穷大时E p为零．通过功能关系可以从分子势能的图象中得到有关分子力的信息，则下列说法正确的是（）A．假设将两个分子从r=r2处释放，它们将相互远离B．假设将两个分子从r=r2处释放，它们将相互靠近C．假设将两个分子从r=r1处释放，它们的加速度先增大后减小D．假设将两个分子从r=r1处释放，当r=r2时它们的速度最大21．（18分）图1所示为某同学研究“在外力一定的条件下，物体的加速度与其质量间的关系”的实验装置示意图．（1）下面列出了一些实验器材：电磁打点计时器、纸带、带滑轮的长木板、垫块、小车和砝码、砂和砂桶、刻度尺．除以上器材外，还需要的实验器材有：．A．秒表 B．天平（附砝码） C．低压交流电源 D．低压直流电源（2）实验中，需要补偿打点计时器对小车的阻力及其它阻力：小车放在木板上，后面固定一条纸带，纸带穿过打点计时器．把木板一端垫高，调节木板的倾斜度，使小车在不受绳的拉力时能拖动纸带沿木板做运动．（3）实验中，为了保证砂和砂桶所受的重力近似等于使小车做匀加速运动的拉力，砂和砂桶的总质量m与小车和车上砝码的总质量M之间应满足的条件是．这样，在改变小车上砝码的质量时，只要砂和砂桶质量不变，就可以认为小车所受拉力几乎不变．（4）如图2所示，A、B、C为三个相邻的计数点，若相邻计数点之间的时间间隔为T，A、B间的距离为x1，B、C 间的距离为x2，则小车的加速度a= ．已知T=0.10s，x1=5.90cm，x2=6.46cm，则a= m/s2（结果保留2位有效数字）．（5）在做实验时，该同学已补偿了打点计时器对小车的阻力及其它阻力．在处理数据时，他以小车的加速度的倒数为纵轴，以小车和车上砝码的总质量M为横轴，描绘出﹣M图象，图3中能够正确反映﹣M关系的示意图是．22．（16分）如图所示为竖直放置的四分之一圆弧轨道，O点是其圆心，半径R=0.8m，OA水平、OB竖直．轨道底端距水平地面的高度h=0.8m．从轨道顶端A由静止释放一个质量m=0.1kg的小球，小球到达轨道底端B时，恰好与静止在B点的另一个相同的小球发生碰撞，碰后它们粘在一起水平飞出，落地点C与B点之间的水平距离x=0.4m．忽略空气阻力，重力加速度g=10m/s2．求：（1）两球从B点飞出时的速度大小v2；（2）碰撞前瞬间入射小球的速度大小v1；（3）从A到B的过程中小球克服阻力做的功W f．23．（18分）（1）从宏观现象中总结出来的经典物理学规律不一定都能适用于微观体系．但是在某些问题中利用经典物理学规律也能得到与实际比较相符合的结论．例如，玻尔建立的氢原子模型，仍然把电子的运动看做经典力学描述下的轨道运动．他认为，氢原子中的电子在库仑力的作用下，绕原子核做匀速圆周运动．已知电子质量为m，元电荷为e，静电力常量为k，氢原子处于基态时电子的轨道半径为r1．a．氢原子处于基态时，电子绕原子核运动，可等效为环形电流，求此等效电流值．b．氢原子的能量等于电子绕原子核运动的动能、电子与原子核系统的电势能的总和．已知当取无穷远处电势为零时，点电荷电场中离场源电荷q为r处的各点的电势φ=k．求处于基态的氢原子的能量．（2）在微观领域，动量守恒定律和能量守恒定律依然适用．在轻核聚变的核反应中，两个氘核（H）以相同的动能E0=0.35MeV做对心碰撞，假设该反应中释放的核能全部转化为氦核（He）和中子（n）的动能．已知氘核的质量m D=2.0141u，中子的质量m n=1.0087u，氦核的质量m He=3.0160u，其中1u相当于931MeV．在上述轻核聚变的核反应中生成的氦核和中子的动能各是多少MeV？（结果保留1位有效数字）24．（20分）如图所示，在磁感应强度为B的水平匀强磁场中，有一竖直放置的光滑的平行金属导轨，导轨平面与磁场垂直，导轨间距为L，顶端接有阻值为R的电阻．将一根金属棒从导轨上的M处以速度v0竖直向上抛出，棒到达N处后返回，回到出发点M时棒的速度为抛出时的一半．已知棒的长度为L，质量为m，电阻为r．金属棒始终在磁场中运动，处于水平且与导轨接触良好，忽略导轨的电阻．重力加速度为g．（1）金属棒从M点被抛出至落回M点的整个过程中，求：a．电阻R消耗的电能；b．金属棒运动的时间．（2）经典物理学认为，金属的电阻源于定向运动的自由电子与金属离子的碰撞．已知元电荷为e．求当金属棒向下运动达到稳定状态时，棒中金属离子对一个自由电子沿棒方向的平均作用力大小．物理试题答案13．【解答】AB、光电效应说明光具有粒子性，故A正确，B错误；CD、光的干涉、衍射现象说明光具有波动性，并不能区别横波与纵波，故CD错误；故选：A．14．【解答】A、根据图象可知波长λ=4m，由于不知道波速，无法求解周期，故A错误，B正确；C、此时刻质点A位于平衡位置处，速度最大，故C错误；D、此时刻质点B处于波峰处，加速度最大，故D错误．故选：B15．【解答】以球为研究对象，分析其受力情况：重力mg、悬绳对球的拉力和墙壁对球的支持力，根据平衡条件，有：T=N=mgtanθ，由于θ＜45°，所以N＜mg．故选：C．16．【解答】A、正电荷在电场中，在电势高的位置，电势能越大，故A正确，B错误；C、等势面的疏密代表场强的大小，故A点的场强小于B点的场强，故CD错误；故选：A17．【解答】当a、b端加直流电压时，L1灯不发光，L2灯正常发光；当加同样电压的交流电源时，L1灯发光，L2灯发光较暗．知线框A中为电容器，因为电容隔直通交．线框B中是电感线圈，因为电感线圈对交流电有阻碍作用，对直流电无阻碍作用．故选：D．18．【解答】过山车在运动过程中，受到重力和轨道支持力作用，只有重力做功，机械能守恒，动能和重力势能之间相互转化，则当重力势能最大时，过山车的动能最小，即速度最小，根据题意可知，车的中点B通过P点时，质心的位置最高，重力势能最大，则动能最小，速度最小，故B正确．故选：B19．【解答】A、由图可知当转换开关S旋到位置1、2位置是电流表，接1时分流电阻相对更小，故接1时电表的量程更大；故A正确；B、测量电阻时欧姆表内部应接电源，由图可知测电阻只有接3或4；A与电源的负极相连，故A为红表笔；故B错误；C、要测量电压，电流表应与电阻串联，由图可知当转换开关S旋到位置5、6时，故C错误；D、要测量电压，电流表应与电阻串联，由图可知当转换开关S旋到位置5、6时；测量电压，电流表所串联的电阻越大，所测量电压值越大，故当转换开关S旋到6的量程比旋到5的量程大．故D错误．故选：A．20．【解答】由图可知，两个分子从r=r2处的分子势能最小，则分子之间的距离为平衡距离，分子之间的作用力恰好为0．A、B、C、结合分子之间的作用力的特点可知，当分子间距离等于平衡距离时，分子力为零，分子势能最小，所以假设将两个分子从r=r2处释放，它们既不会相互远离，也不会相互靠近．故A错误，B错误，C错误；D、由于r1＜r2，可知分子在r=r1处的分子之间的作用力表现为斥力，分子之间的距离将增大，分子力做正功，分子的速度增大；当分子之间的距离大于r2时，分子之间的作用力表现为引力，随距离的增大，分子力做负功，分子的速度减小，所以当r=r2时它们的速度最大．故D正确．故选：D21．【解答】（1）本实验中需测小车质量，则需要天平，电磁打点计时器需要低压交流电源，故选：BC（2）平衡摩擦力时，把木板一端垫高，调节木板的倾斜度，使小车在不受绳的拉力时能拖动纸带沿木板做匀速直线运动即可；（3）根据实验误差的来源，在

（16分）①仅仅在刚刚过去的2012年，我们便听到了众多老牌纸媒的噩耗。

拥有79年历史的美国老牌杂志《新闻周刊》宣布，最后一期印刷版杂志发行后停刊，全面转向数字杂志。

德国《纽伦堡晚报》、《法拉克福论坛报》、《德国金融时报》相继停刊，法国第二大经济类报纸《论坛报》也寿终正寝。

这股“纸媒之死”的洪流当然也淹没了图像类新闻杂志。

②早在1972年美国《LIFE》第一次停刊之时，专栏作家沙纳·亚历山大当时还不肯相信：“摄影杂志没有死，人们既未停止阅读，也没有丧失对周围世界的兴趣。

”这话说得固然不错，然而他没有料到脱离了纸这种介质，人们依然可以通过电子屏幕观看图像，亦能够畅游网络，保持着对周围世界更浓厚的兴趣。

我们可以通过Google Books阅读自《LIFE》创刊至1972年的所有文章，也能够看到它所有的精彩版面。

像纸张扼杀竹简一样，数字化把成吨的纸张简化到一张光盘上。

今天这个时代并没有失去任何新闻和惊心动魄的照片。

相反的，图像类纸质媒体和新闻摄影师们却正感到自己失去了一个时代。

③然而旧的死去并不一定是件坏事。

正如法国VU图片社创始人Christian说道：“我们已经有了获取新闻和图片的新渠道。

纸张可以算的上是一种奢侈行为。

我们为什么还要砍伐大量树木，污染大片水源？”况且，新形式的报道并不亚于传统媒体。

轰动一时的“维基解密”就是新式媒体的代表。

2010年7月，维基联合《卫报》发布“阿富汗战争日记”专题，内容包含超过几万份关于阿富汗战争的文档。

这让习惯了在周六或周日的清晨，早早起床，守候火箭队比赛的球迷们怅然若失。

从现在开始，必须习惯没有姚明的NBA。

多少人，看着他一步步从稚嫩的菜鸟到NBA球队的核心，从一个普通球员成为举世瞩目的中国名片，从一个孩子成长为俱乐部老板、孩子的父亲。

9年间，伤痛、荣誉和责任如影随形，这个不再只属于他自己的名字，如何一步步成为了一个国家的符号？A．大庭广众 B．怅然若失 C．举世瞩目 D．如影随形3．下列各句中，没有语病的一项是（）（3分）A．根据2015届高考模拟中国城乡老年人口状况追踪调查数据显示看，中国拥有自主产权住房的城市老年人为79.2%，表明大量城市老年人将是”以房养老”模式的受益主体。

B．近日，一则“立顿茶农药残留超标”的消息，引起社会广泛关注，我国的农药残留限量标准是如何制定的？中外标准存在差异的原因是什么？对于广大消费者来说，这些无疑不是大问题。

汽车租赁中的车辆保险费用分摊范本近年来，汽车租赁行业的发展迅速，租车已成为一种常见的出行方式。

然而，在租车过程中，车辆保险费用分摊问题一直备受争议。

为了明确车辆保险费用的分摊范本，保障租车双方的权益，本文将对汽车租赁中的车辆保险费用分摊进行探讨。

一、保险费用的定义及计算方式在汽车租赁中，保险费用指的是为了保障车辆投保人和驾驶人的车辆安全而支付的费用。

计算保险费用时，通常会考虑车辆的价值、车型、驾驶人的驾龄和行驶记录等因素。

二、车辆保险费用的责任划分1.基本强制保险根据我国法律规定，每一辆机动车都必须购买基本强制保险，即交强险。

交强险保障的是在道路交通事故中由被保险人负责的人身伤亡、财产损失责任，费用由所有机动车车主共同分摊。

2.商业保险除了基本强制保险外，车辆租赁公司还可以按照客户的需求为租车提供商业保险，例如车损险、第三者责任险等。

商业保险的费用由租车双方通过协商决定，并在租车合同中明确注明。

三、车辆保险费用分摊的原则1.保险费用由使用方承担汽车租赁中，保险费用应由租车使用方承担。

使用方在租车之前应明确了解并同意支付相应的保险费用。

2.按照使用时间分摊车辆保险费用的分摊应根据租车的使用时间进行合理划分。

通常情况下，按照天数进行分摊是一种常见的方式。

四、车辆保险费用的分摊例子假设小明在租赁一辆汽车，租期为7天，每日租金为100元，保险费用为50元/天。

则车辆保险费用的分摊可以按照以下方式计算：保险费用总额 = 每日保险费用 ×租期天数保险费用总额 = 50元/天 × 7天 = 350元小明需要支付的保险费用 = 每日租金 ×租期天数 ×保险费用占租金比例小明需要支付的保险费用 = 100元 × 7天 × 50% = 350元五、车辆保险费用的支付方式车辆保险费用的支付方式可以根据租车双方的协商而定。

一种常见的做法是，在租车时支付全部保险费用，然后在还车时根据实际使用天数进行退还或调整。
