山西省山西大学附属中学2018届高三下学期3月模块诊断理科综合物理试题
山西大学附中2017-2018学年高三年级3月模拟考试理科综合试题物理部分二、选择题：本题共有8小题，每小题6分。
在每小题给出的四个选项中，第14题到18题只有一选项符合题目要求，第19题到21 题有多项符合题目要求。
全选对的得6分，选对但不全的得3分，有错选得的0分。
1. 物块A、B放在光滑水平面上并用轻质弹簧相连，如图所示。
今对物块A、B分别施以方向相反的水平力F1、F2，且F1大于F2。
则弹簧的示数（）A. 一定等于F1+F2；B. 一定等于F1-F2；C. 一定大于F2小于F1；D. 条件不足，无法确定。
【答案】C【解析】两个物体一起向左做匀加速直线运动，对两个物体整体运用牛顿第二定律:F1-F2=（M+m）a再对物体1受力分析，运用牛顿第二定律，得到:F1-F=Ma由两式解得；由于F1大于F2，故F一定大于F2小于F1,故选C.点睛：本题关键是首先要认识到该题中的两个物体受力后不能在光滑的水平面上静止，而是一起做匀加速直线运动．能否意识到这一点，与平时的对题目进行受力分析的习惯有关，要注意对大小的题目进行受力分析.2. 如图所示，a为放在赤道上相对地球静止的物体，随地球自转做匀速圆周运动，b为沿地球表面附近做匀速圆周运动的人造卫星（轨道半径等于地球半径），c为地球的同步卫星，以下关于a、b、c的说法中正确的是（）A. a、b、c做匀速圆周运动的向心加速度大小关系为a b>a c>a aB. a、b、c做匀速圆周运动的角速度大小关系为ωa=ωc>ωbC. a、b、c做匀速圆周运动的线速度大小关系为v a=v b>v cD. a、b、c做匀速圆周运动的周期关系为T a>T c>T b【答案】A【解析】地球赤道上的物体与同步卫星具有相同的角速度，所以ωa=ωc，根据a=rω2知，c 的向心加速度大于a的向心加速度．根据得b的向心加速度大于c的向心加速度．由可知ωb>ωc, 故A正确，B错误．地球赤道上的物体与同步卫星具有相同的角速度，所以ωa=ωc，根据v=rω，c的线速度大于a的线速度．根据得b的线速度大于c 的线速度，故C错误；卫星C为同步卫星，所以T a=T c，根据得c的周期大于b的周期，故D错误；故选A．点睛：地球赤道上的物体与同步卫星具有相同的角速度和周期，根据v=rω，a=rω2比较线速度的大小和向心加速度的大小，根据万有引力提供向心力比较b、c的线速度、角速度、周期和向心加速度大小．3. 用长度为L的铁丝绕成一个高度为H的等螺距螺旋线圈，将它竖直地固定于水平桌面．穿在铁丝上的一珠子可沿此螺旋线圈无摩擦地下滑．这个小珠子从螺旋线圈最高点无初速滑到桌面经历的时间为（）A. B. C. D. L【答案】D【解析】将螺线圈分割为很多小段，每一段近似为一个斜面，由于螺旋线圈等螺距，说明每一小段的斜面倾角相同，设为θ；根据几何关系，有①物体做加速度大小不变的加速运动，根据牛顿第二定律，有mgsinθ=ma解得a=gsinθ②由于物体与初速度和加速度大小相同的匀加速直线运动的运动时间完全相同，故根据位移时间关系公式，有L=at2③由①②③解得，故选D．点睛：本题关键运用微元法将螺旋线圈分割为很多倾角相同的斜面，然后根据牛顿第二定律求解出加速度，确定物体的运动特点，最后根据运动学公式列式求解.4. 在下列四个核反应方程中，x表示中子的是（）A. P→Si＋xB.C. D. Al＋He→P＋x...【答案】D【解析】A反应中的x表示正电子；B反应中的x表示质子；C反应中的x表示负电子；D反应中的x表示质子；故选D.5. 如图所示为两光滑金属导轨MNQ和GHP，其中MN和GH部分为竖直的半圆形导轨，NQ和HP 部分为水平平行导轨，整个装置置于方向竖直向上、磁感应强度大小为B的匀强磁场中。

Homo Deus is as famous as Sapiens internationally33. Where would you most probably find this text?A In a magazine. B. On a website. C In a brochure D. In a book adBDear Seth,Y ou’re only three years old, and at this point in your life you can’t read, much less understand what I’m going to try to tell you in this letter. But I’ve been thinking a lot about the life that you have ahead of you, about my life so far as I reflect on what I’ve learned, and about my role as a dad in trying to prepare you for the trials that you will face in the coming years.I hope to help you along your path by sharing some of the best of what I’ve learned. As with any advice, take it with a grain of salt. What works for me might not work for you.Life can be cruelThere will be people in your life who won’t be very nice. They’ll tease you because you’re different, or for no good reason. They might try to bully you or hurt you. Ther e’s not much you can do about these people except to learn to deal with them, and learn to choose friends who are kind to you, who actually care about you, who make you feel good about yourself. When you find friends like this, hold on to them, treasure them, spend time with them, be kind to them, love them.There will be times when you are met with disappointment instead of success. Life won’t always turn out the way you want. This is just another thing you’ ll have to learn to deal with. But instead of letting these things get you down, push on. Accept disappointment and learn to persevere, to pursue your dreams despite pitfalls. Learn to turn negatives into positives, and you ll do much better in life.You will also face heartbreak and abandonment by thos e you love. I hope you don’t have to face this too much, but it happens. Again, not much you can do but to heal, and to move on with your life. Let these pains become stepping stones to better things in life, and learn to use them to make you stronger.Lif e isn’t a competitionYou will meet many people who will try to do better than you, in school, in college, at work. They’ll try to have nicer cars, bigger houses, nicer clothes, cooler gadgets. To them, life is a competition--- they have to do better than their peers to be happy.H ere’s a secret: Life isn’t a competition. If you spend that journey always trying to impress others, to outdo others, you’re wasting your journey. Instead, learn to enjoy the journey. Make it a journey of happiness, of constant learning, of continual improvement, of love.D on’t worry about having a nicer car or house or anything material, or even a better-paying job. None of that matters a whit, and none of it will make you happier. Y ou’ll acquire these things and then only want more. Instead, learn to be satisfied with having enough and then use the time you would have wasted trying to earn money to buy those things to do things you love.Finally, know that I love you and always will. You are starting out on a weird, scary, daunting, but ultimately incredibly wonderful journey, and I will be there for you when I can.Love,Your Dad34.What does the underlined phrase “with a grain of salt” mean?A.eating something together with some saltB. believing something firmlyC. taking it for grantedD. not accepting something firmly35. According to the letter, which one is NOT the example to prove the cruelty of life?A.Your classmate tease, bully or hurt you.B. You are too busy to spend time with your parents.C. Your best friend betrays you by giving away your work.D. You fail in the mid-term exam despite your hard work36. The last part Life isn’t a competition is mainly developed by .A. making comparisonsB. analyzing causesC. telling storiesD. asking and answering questions37. The purpose of the letter is to .A. Tell his son that he loves himB. try to persuade his son to get along well with his friendsC. make his son realize failure is unavoidable and he should get ready for thatD. prepare his son for the challenges he will face in the futureCWould you buy a car that releases calming smells into the air when you are stuck in heavy traffic? Would you buy a robot that smells like a human being?Many people have seen the 3-D computer-made environments of virtual reality (VR). Now these virtual worlds will not just look and sound real. Researchers have created VR environments that even smell like the real thing. With the new technology, users open a virtual door and step into a new environment, like a rainforest. After they enter this virtual world, special equipment releases forest-like smells into the air to make the experience seem more real.Suzanne Fisher-Murray said, "It is a really wonderful experience that you have because you're exploring this environment and you have smells with it."In the United States, Smell-O-Vision was designed to provide smells during the showing of a movie. The Smell-O-Vision system was briefly popular in the 1960s. Now, University of Sussex researcher Emanuela Maggioni says it is close to becoming popular again. "The connection with emotions, memories, and ... the sense of smell," Maggioni said. "It is unbelievable what we can do with technology."The uses for smell technology are not just limited to films and the performing arts. Researchers showed a computer program where users could imagine themselves driving a car. The system included a special smell-spraying machine. Dmitrijs Dmitrenko said, "We wanted to deliver the smell of lavender（薰衣草）every time the person drives over the speed limit. We choose lavender because it's a very calming smell."Scientists are experimenting with smell instead of sounds or image-based alerts on telecommunications equipment. And businesses are already using smell to influence people's behavior. "Not only ... in stores ... But on the other side, you can create and stimulate immediate buying," Maggioni said. "So you're in a library and you smell coffee and actually you are unconsciously having the need to drink a coffee."ing smell technology, researchers make VR environments .A. have a smell of a rainforestB. even smell like real onesC. look like a 4-D environmentD. impress people with a virtual world39. The example of Smell-O-Vision proves that .A. America is the first to use smell technologyB. cinemas are the most suitable for smell senseC. smell technology has been tried beforeD. it was out of date to use smell-spraying devices40. How is smell technology used by businessmen?A. To make buyers understand salesmen betterB. To remind people of their unrealistic buyingC. To help customers choose their favorite goodsD. To encourage people to buy something suddenly.41. What is the main idea of the passage?A. The developments of smell technologyB. A major breakthrough of smell technology.C. The sense of smell in human communicationD. The advanced smell-spraying machinesDAntiquities are ancient objects and artworks. Museums acquire works to display from many different sources. Sometimes they purchase them. Other times they receive donations. Today there are strict rules forbidding art that has been stolen from other countries. However, antiquities that have been at museums for decades or even centuries may have arrived there by questionable means. Now, some countries claim that museums have a responsibility to return these antiquities to their original locations.There are many examples of this debate. Perhaps the most famous is the argument between Greece and the UK over the Elgin marbles. In the early 19th century, the Earl（伯爵）of Elgin had numerous sculptures taken from Greece to the UK. When Elgin did this, Greece was still a part of the Ottoman Empire. He claimed that he had received a permit to export the sculptures. Today the marbles are on display in the British Museum. However, Greece wants them to be returned to their original location.Should museums return these antiquities? Experts disagree. Malcolm Bell III says yes. Bell is a retired professor of art at the University of Virginia. He says, “Many antiquities and artworks have special cultural value for a particular community or nation. When these works are removed from their original cultural setting they lose their context and the culture loses a part of its history.”According to Bell, a country’s request for the return of an antiquity usually has a strong legal basis. It was exported illegally, and is now stolen property. He called the return of antiquities “an expression of justice.”James Cuno says not always. Cuno is president of an art museum in Los Angeles. He is also the author of the book Who Owns Antiquity?. Cuno agrees that museums have “a social and legal responsibility” to return illegally exported antiquities. However, he doesn’t support the return of legally required works.“An area of land held today by a given nation-state in the past likely belonged to a different political entity（实体）. Even if one wanted to reunite scattered works of art, where would one do so? Which among the many countries, cities, and museums in possession of parts of a work of art should be the chosen ‘home’ of the reunited work?’ Cuno believes that museums should collect art from the world’s diverse cultures. “This should be done through purchase or long-term loan and working in cooperation with museums and nations around the world.”This debate is far from over. As a complex question with no easy answer, the issue requires more study.42.The passage mainly discusses .A. the return of antiquities B the sources of ancient objectsC. the cultural value of artworksD. the responsibility of museums43. For the case of the marbles. Greece and the UK mainly argue over .A. the time of keeping themB. the real country of originC. the identity of the exporterD. the means of acquiring them44. According to the passage, Cuno thinks .A. artworks become valueless away from their cultureB. there is no clear answer to giving back antiquitiesC. museums are responsible for reuniting works of artD. the request for recovering artworks aims to promote justice45. As to the debate, we can learn that .A. the legality of antiquities seems a key factorB. the opinions of experts are completely differentC. museums should look into the sources of antiquities they ownD. the return of antiquities is unlikely due to practical difficulties第二节共5小题:每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。

AAmsterdam’s Best Flea MarketsIjhallen Flea MarketFirst or second weekend of every monthPerhaps the most impressive of them all is Ijhallen, located in the north of Amsterdam. With more than 1,500 stands and 3,000 free parking spaces, the monthly market attracts visitors from not only the Netherlands, but Europe-wide.There is a five euro admission fee, but you can be pretty sure that you can browse second-hand treasures for most of the day. Anything and everything can be found here; old guitars and antique chairs, art prints and military gear.Noordermarkt Flea MarketSaturday, 9am-4pmMonday, 9am-2pmIn the centre of the Jordaan, the Noordermarkt Flea Market on Saturdays includes vintage(老式的) goods and organic food produce from local farmers.On Mondays, the market transforms into an antique-hunter’s goldmine. There are piles of vintage clothes, antique books, coins and furniture.Waterloopein MarketMonday-Saturday, 9am-6pmThe most centrally located of all flea markets in Amsterdam, Waterlooplein Market offers visitors a range of snacks, second-hand clothes and vintage treasures.There’s a maze of second-hand goods, from old globes and hanging lamps, to African drums, antique rugs and used bikes.Spui Book MarketFriday 10am-6pmIdeally situated among bookstores, you’ll find a collection of tents sheltering second-hand and antique books at the book market on Spui.You can find a variety of literature from biographies and poetry to fantasy-fiction, history, psychology and geography. While most books are from theNetherlands, some English and international titles are for sale. As well as antique maps, prints and record.1. Which flea market do you need to pay some extra money?A. Ijhallen Flea Market.B. Noordermarkt Flea Market.C. Waterlooplein Market.D. Spui Book Market.2. What can you pick up at Noordermarkt Flea Market?A. You can get enough parking space.B. You can choose a range of snacks.C. You can buy some fresh vegetables.D. You can dig some gold mines here.3. When is a good time to visit a favorite market for a crazy book fan?A. First weekend of every month.B. Friday, 10am-6pm.C. Monday, 9am-6pm.D. Saturday, 9am-4pm.BConstruction on Knolly’s Tunnel began in 1896, and it was opened on August 13th, 1898 by the man it was named after--Sir Clement C. Knolly, Acting Governor of Trinidad. It linked Rio Claro with Port of Spain. Its architecture is still admired and studied today, and many are amazed that Knolly’s Tunnel has stood up to the earth’s movement over so many years.Much research is being done on the tunnel. At the top of Knolly’s Tunnel are cottages covered with leaves, where visitors can sit and enjoy the beauty of nature. Standing at the beginning of Knolly’s Tunnel, you can see nothing but the tiny light at the end. The train tracks have been removed and replaced with small stones. Visitors can drive through the tunnel or walk through, but should do so in groups for safety. In the old days, there were no lights, but now there are street lights on the way to the tunnel, though not inside.On your way in, you may notice some manholes on the walls of the tunnel. These were there for individuals to step into for safety as the train passed. Knolly’s Tunnel can be accessed through Tabaquite and through Mitchell Gap. The road was recently improved, but is better when you enter from Tabaquite, and there are signs on the road directing you to Knolly’s Tunnel.On the drive to Knolly’s Tunnel there are two other cottages where visitors can sit and just enjoy nature. At the site itself, there is nothing to purchase to eat or drink, but in Tabaquite there are several bars, a restaurant, and food outlets.A gas station and a health centre are also close by.For those who admire architecture, Knolly’s Tunnel is a must-see when visiting Trinidad. For the nature lovers, there is no better place for them to be and for the historians, they can walk or drive through Knolly’s Tunnel knowing that many of our ancestors toiled (worked hard) on its structure. So when you visit Trinidad, don’t forget to take a look at Knolly’s Tunnel!4. Knolly’s Tunnel is special in __________.A. its environmentB. its functionC. its locationD.its architecture5. The underlined word “site” in the paragraph 4 refers to ________.A. TrinidadB. TabaquiteC. Mitchell GapD. Knolly’s Tunnel6. What is the purpose of the passage?A. To suggest a visit to Knolly’s Tunnel.B. To introduce the history of Knolly’s Tunnel.C. To evaluate the value of Knolly’s Tunnel.D. To witness the change of Knolly’s Tunnel7. The passage above is probably taken from ____________.A. a geography textbookB. a travel journalC. a sports reportD. a health and fitness magazineCBlue Planet II’s latest episode focuses on how plastic is having a disastrous effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench, have plastic in their stomachs. Indeed, the oceans are drowning in plastic.Though it seems now that the world couldn’t possibly function without plastics, consumerplastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s; the same decade that plastic packaging began gaining in popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science.We put all these plastics into the environment and we still don’t really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent.And it’s not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning to the same degree as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers (否认者), at least so far. To do something about it, we don’t have to remake our planet energy system.This is not a problem where we don’t know what the solution is. We know how to pick up garbage. Anyone can do it. We know how to dispose (处理) of it. We know howto recycle. We can all start by thinking twice before we use single----use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag----when taken collectively, these choices really do make a difference.8. Why is plastics pollution research still a very early science?A. The plastics pollution research is too difficult.B. Plastics have produced less pollution than coal.C. The world couldn’t possibly function without plastics.D. Plastics have gained in popularity too fast for science to catch up.9. How did the author support his opinion in Paragraph 3?A. By statistics.B. By quotations from leading experts.C. By using examples from his own experience.D. By comparison and contrast.10. What can we infer about climate change?A. Climate change is caused by human activities.B. Some people hold some doubts about climate change.C. Climate change is less important than ocean pollution.D. Ocean plastic is more complicated than climate change.11. What is the main idea of this passage?A. Ocean plastic is a global issue.B. The oceans become choked with plastic.C. Blue Planet II has left viewers heartbroken.D. Plastics gain in popularity all over the worldDMaths and MusicAn excellent way to kill a conversation is to say you are a mathematician. Tell others you are also a musician, however, and they will be hooked. Although there are obvious similarities between mathematical and musical activity, there is no direct evidence for the kind of magical connection many people seem to believe in.I’m partly referring here to the “Mozart effect”, where children who have been playing Mozart compositions are supposedly more intelligent, including at maths, than other children. It is not hard to see why such a theory would be popular: we would all like to become better at maths without putting in any effort. But the conclusions of the experiment that expressed the belief in the Mozart effect were much more modest. If you want your brain to work better, you clearly have to put in hard work. As for learning to play the piano, it also takes effort.Surely a connection is quite reasonable. Both maths and music deal with abstract structures, so if you become good at one, then it is likely that you become good at something more general that helps you with the other. If this is correct, it wouldshow a connection between mathematical and musical ability. It would be more like the connection between abilities at football and tennis. To become better at one, you need to improve your fitness and coordination (协调). That makes you better at sport and probably helps with the other.Abstract structures don’t exist only in maths and music. If you learn a language then you need to understand its abstract structures like gramm ar. Yet we don’t hear people asking about a connection between mathematical and linguistic (语言的) ability. Maybe this is because grammar feels mathematical, so it wouldn’t be surprising that mathematicians were better at learning grammar. Music, however, is strongly tied up with feelings and can be enjoyed even by people who know little about it. As such, it seems different from maths, so there wouldn’t be any connection between the two.Let’s see how we solve problems of the “A is to B as C is to D”kind. These appear in intelligence tests but they are also important to both music and maths. Consider the opening of Mozart’s Eine Kleine Nachtmusik (小夜曲).The second phrase (小节) is a clear answer to the first. The listener thinks: “The first phrase goes upward and uses the notes of a G major chord (和弦); what would be the corresponding phrase that goes downward and uses the notes of a D7?” Music is full of puzzles like this. If you are good at them, expectations will constantly be set up in your mind. The best moments surprise you by being unexpected, but we need the expectations in the first place.12. What does the author say about “Mozart effect”？A. The goal of it was not carefully thought about.B. The findings from it gave people wrong information.C. The interest people showed in it was unexpected.D. The way it was carried out proved to be ineffective.13. The author mentioned football and tennis in Paragraph 3 to show that ______.A. football and tennis are played in a similar way.B. certain skills may be developed through practice.C. music and maths have something in common.D. abstract structures bring benefits to various fields.14. We can infer from Paragraph 4 that ______.A. language seems more like maths than music does.B. language is less appealing to learners.C. mathematicians are good at music learning.D. the structure of language is easier to learn than that of music.15. What does the writer intend to state in the last paragraph?A. How music differs from maths.B. Why musicians possess mathematical abilities.C. Why Mozart is so highly considered by mathematicians.D. How abstract thinking applies to both music and maths.第二节（共5小题：每小题3分，满分15分）根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

25．（19分）
【详解】（1）由题意可知电子在磁场中的轨迹半径r ＝L 3
由牛顿第二定律得Bev 0＝m v 20r
（2分） 电子的比荷e m ＝3v 0BL （2分）
（2）若电子能进入电场中，且离O 点右侧最远，则电子在磁场中
运动圆轨迹应恰好与边AD 相切，即粒子从F 点离开磁场进入电
场时，离O 点最远。
设电子运动轨迹的圆心为O ′点。
则OF ＝x m ＝2L 3

34．（15分） （1）ACE(5分) （2）①15°(4分) ②2d (6分)
【详解】(1)由图象可知，波长λ＝4 m ，振幅A ＝ 2 cm ，由题意知，波速v ＝100 m/s ，波源
的振动周期T ＝λv
＝0.04 s ，故A 正确；a 、b 两质点不可能同时到达平衡位置，故B 错误；波沿x 轴正方向传播，0时刻a 质点正在向下运动，t ＝0.04 s ＝T ，一个周期后a 质点回到了
原来的位置，仍然正在向下运动，故C 正确；从t ＝0到t ＝0.01 s 时间内，0.01 s ＝T 4
，四分之一个周期的时间内，质点运动的路程一定大于A 2＝1 cm ，故D 错误；该波的频率f ＝1T
＝25 Hz ，与频率是25 Hz 的简谐横波相遇时可能发生波的干涉现象，故E 正确．
