2022年中考物理真题专项六 测量电功率(2)(通用版)
专项六测量电功率（第2期）（2022·湖北武汉）1. 某同学用如图甲所示的电路测量小灯泡的电功率。
实验中电源电压保持不变，小灯泡的额定电压是3.8V。
（1）图甲中有一根导线接错了，请你在这根导线上：打“×"，并补画出正确的那根导线______；（2）正确连接电路后，小灯泡正常发光时电流表示数如图乙所示，则小灯泡正常发光时的电流是______A，小灯泡的额定功率是______W；（3）测出小灯泡额定功率后，该同学接着移动滑动变阻器的滑片，当电流表的示数为0.32A时，电压表的示数不可能是______（填标号）。
A.3.9VB.4.0VC.4.1V【答案】①. ①. 0.3 ①. 1.14 ①. AB【解析】【详解】（1）[1]原电路中，电流表与滑动变阻器串联后和灯泡并联，且电压表串联在电路中，这些是错误的，电流表、滑动变阻器和灯泡应串联，电压表并联在灯泡两端，如图所示（2）[2]由图乙可知，电流表的量程为0~0.6A ，根据指针的位置可得，电流表的示数为0.3A 。
[3]小灯泡正常发光时的电流为0.3A ，因为小灯泡正常发光，所以其两端电压等于小灯泡的额定电压，即3.8V ，根据功率公式P =UI 可得，小灯泡的额定功率为=3.8V 0.3A=1.14W P U I =⨯额额（3）[4]正常发光时，灯泡的电阻为3.8V =12.67Ω0.3AU R I =≈额正 当电流表的示数为0.32A 时，若电压表的示数为3.9V ，则此时灯泡的电阻为111 3.9V =12.18750.32AU R I ==Ω 若电压表的示数为4.0V ，则此时灯泡的电阻为221 4.0V =12.50.32AU R I ==Ω 若电压表的示数为4.1V ，则此时灯泡的电阻为331 4.1V =12.81250.32AU R I ==Ω 又因为灯泡的电阻随灯泡两端电压的增大而增大，所以电压为3.9V 、4.0V 和4.1V 时，灯泡的电阻应该要大于R 正，但是很明显，只有3R R >正，符合条件，所以电压表的示数不可能是3.9V 和4.0V 。

实验6 弯曲性能测定 (2)
实验六 弯曲性能测定一、 目的要求1. 明确弯曲试验为何可作为复合材料的筛选试验缘故。
2. 了解方法要点，测试塑料及玻璃钢弯曲强度。
二、 原理复合材料的弯曲试验中试样的受力状态比较复杂，有拉力、压力、剪力、挤压力等，因而对成型工艺配方、试验条件等因素的敏感性较大。
用弯曲试验作为筛选试验是简单易行的，也是比较适宜的。
玻璃纤维增强塑料弯曲性能试验方法（GB1449－83）适用于测定玻璃纤维织物塑料板材和短切玻璃纤维增强塑料的弯曲性能，包括弯曲强度、弯曲弹性模量、规定挠度下的弯曲应力、弯曲载荷－挠度曲线。
GB1042－79适用于塑料弯曲性能测定。
1.弯曲强度。
弯曲试验一般采用三点加载简支梁，即将试样放在两支点上，在两支点间的试样上施加集中载荷，使试样变形直至破坏时的强度为弯曲强度223bhPlf =σ 式中f σ——弯曲强度（或挠度为1.5倍试样厚度时的弯曲应力），Mpa ； P ——破坏载荷（或最大载荷，或挠度为1.5倍试样厚度时的载荷），N ；l ——跨距，cm ；b 、h ——试样宽度、厚度，cm 。
2．弯曲弹性模量。
它是指在比例极限内应力与应变比值fbh Pl E f ∆⋅∆⋅=334 式中 f E ——弯曲弹性模量，Mpa ；P ∆——载荷－挠度曲线上初始直线段的载荷增量，N ； f ∆——与载荷增量P ∆对应的跨距中点处的挠度增量，cm 。
3．某些试验由于特殊要求，可测定表观弯曲强度，即超过规定挠度时（如超过跨距的10％）载荷达到最大值时的弯曲应力。
在此大挠度试验时，弯曲应力最好用下面的修正公式：]){41[2322l f bh Pl f+=σ式中 f ——试样跨距中点处的挠度，cm 。
三、 方法要点（一） 试样试样型式和尺寸见图55-1，表55-1、表55-2、表55-3。
（二） 试验条件与步骤弯曲试验装置示意图55-2。
加载上压头圆柱面半径R 为5±0.1mm ，支座圆角半径r 为2±0.2mm （当h ﹥3mm 时）和0.5±0.2mm （当h ≤3mm 时），若试样出现明显支座压痕，r应改为2mm 。

My father was a dairy man and he had been working his entire life. For him, getting up at 5 a.m. and working a couple of hours before I went to school, and then 16 more after school until there was not enough 17 to see, were normal.My father considered putting good work ethics in me to be very 18 . He began to show me these, not through 19 , but through his actions. He would not 20 a job until it was done. He 21 put his all into everything he did. 22 , he showed me this not just in working, but in everything. Like when I was in soccer, I wanted to 23 a game once and he explained to me that I had made a 24 and that even if I just skipped one game, then I did not 25 to play the rest of the games.So the day I started my first job at the age of 14, I was 26 to show my father that I could do it well, and that I was not going to 27 . My entire 28 was to make my father proud of me. I knew that 29 I did, he would not say it in words, but he would show it. My first job was doing 30 for a company. As most of you know, construction is not an easy job, especially being so 31 . When someone as young as I was started working, they would either 32 or get stronger. I got stronger. I worked the 33 I had been taught and I gave that day everything I had. In the end, my boss was impressed. He even called to tell my parents what a good worker I was, and my parents' eyes 34 . From that day on I have worked every job to my full 35 , because that day defined (explain the truth of ) my life. It defined how I was going to work, and I will always stick to it.16.

It's not the first time that he's promised himself this. Being a fashion designer, and an allround crafty(手工的) type, he's often thought he should put his money where his mouth is. But this year he's really going to stick to it. It's partly that he's short of cash, but also that he has recently returned from an inspiring trip around Britain, looking into "make do and mend" for BBC2's Newsnight.He dreamed up the trip a few months ago. The thought of traveling the country-making things as he went, meeting artists and craftspeople-sounded like the perfect way to spend the summer. He'd pack a tent and a sewing machine and off he'd go. But by the time he carried out his plans and hit the road, leaves were already crunching(嘎扎作响) under foot. It seemed crazy to camp with winter on the way; instead, Newsnight viewers offered him board and accommodation in return for help with a craft task. There was a strong response.His tasks ranged from mending a young girl's sweater to making trousers for an old man. Textile(纺织) students in Harpenden offered to pay for his petrol in return for a talk about hats.Roger was really struck by people's growing enthusiasm for making things. He asked a woman group in Sheffield how many could sew, and only a few put up their hands. But when he asked who wanted to learn, nearly everyone responded positively. At the Textile Workshop in Nottingham, the number of classes on offer has doubled in a year, and a sewing club in Leeds is growing by the week. Craft is definitely fashionable at the moment. But over and above fashion, people are learning to appreciate effort and quality again. Perhaps once they rediscover the pleasure to be gained from making something unique, it may stick.Sue Pilchard is in charge of quilts at the V&A, where next spring she'll be putting on the museum's first major quilting exhibition. Sue believes the return to crafting is wrapped up in how they are redefining themselves."There's certainly a movement, towards a new family life. People, especially women, are starting to think about the way they live their lives. It's 40 years since the first women's liberation conference was held in Oxford. Since that time we've been in the workplace, and we've, had the opportunity of choice. Now we're purposely choosing to go back into the home."Whether you agree with that or not, there's something about Christmas that brings out the artistic characteristic in everyone. Whether it's baking pies or decorating the halls, they're all prepared to have a go. So if you fancy making a few presents, try these really simple ideas, each inspired by Roger's recent journey. They make wool gloves or small gifts, and take no longer than 30 minutes each. Playsome songs, settle down with a steaming cup of cocoa, and forget the cold. You'll save yourself a bit of money and spread a little bit of love too!36. Roger promised to make himself a Christmas present this year mainly because .A. all people make presents themselvesB. he was lacking in moneyC. he wanted to save moneyD. he was inspired by his recent trip37. What does Roger mean by saying "put his money where his mouth is"(Paragraph 1)?A. stop talking and take actionB. spend more money on foodC. put money in his mouthD. set aside some money38. When was Roger probably on his trip to Britain?A. Winter.B. Late Autumn.C. Late Summer.D. Spring.39. According to the passage, through crafting people learn to .A. appreciate the efforts in handmade thingsB. keep up with fashionC. have a better understanding of craftD. stick to something interesting40. The last paragraph of the passage implies that .A. making Christmas presents can only convey a bit of your loveB. it would take a long time to prepare a Christmas presentC. people can find their artistic talent in making Christmas presentsD. you can drink a cup of hot cocoa when you make preparationsBFrom the health point of view we are living in an amazing age. We are free from many of the most dangerous diseases. A large number of once deadly illnesses can now be cured by modern medicine. It is almost certain that one day medicines will be found for the most stubborn remaining diseases. The expectation of life has increased greatly. But though the possibility of living a long and happy life is greater than ever before, every day we witness the unbelievable killing of men, women and children on the roads. Man vs the motor-car. It is a never-ending battle which man is losing. Thousands of people the world over are killed or horribly killed each year and we are quietly sitting back and letting it happen.It has been rightly said that when a man is sitting behind a steering wheel (方向盘), his car becomes the extension of his personality. There is no doubt that the motor-car often brings out a man's very worst qualities. People who are normally quiet and pleasant may become unrecognizable when they are behind a steering-wheel. They say, they are ill-mannered and aggressive, willful as two-year-olds and completely selfish. All their hidden angers and disappointments seem to be brought to the surface by the act of driving.The surprising thing is that society smiles so gently on the motorist and seems to forgive his behavior. Everything is done for his convenience. Cities are allowed to become almost uninhabitable because of heavy traffic; towns are made ugly by huge car parks; the countryside is ruined by road networks; and the deaths become nothing more than a number every year, to be easily forgotten.It is high time a world rule was created to reduce this senseless waste of human life. With regard to driving, the laws of some countries are unbelievably lax (不严格) and even the strictest are not strict enough. A rule which was universally accepted could only have an obviously beneficial effect on the accident rate. Here are a few examples of some of the things that might be done. The driving test should be standardized and made far more difficult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through strict tests for safety each year. Even the smallest amount of alcohol in the blood can damage a person's driving ability. Present drinking and driving laws (where they exist) should be made much stricter. Speed limits should be required on all roads. Governments should lay down safety specifications for car factories, as has been done in the USA. All advertising stressing power and performance should be banned. These measures may not sound good enough. But surely nothing should be considered as too severe if it results in reducing the number of deaths. After all, the world is for human beings, not motor-cars.41. What is the main idea of this passage?A. Traffic accidents are mainly caused by motoristsB. Thousands of people the world over are killed each yearC. Only stricter traffic laws can prevent accidentsD. The laws of some countries about driving are too lax42. What does the author think of society toward motorists?A. Society laughs at the motoristsB. Society forgives their rude drivingC. Victims of accidents are nothingD. Huge car parks are built in the cities and towns43. What does the author mean by saying “his car becomes the extension of his personality” in Para. 2?A. Driving can represent his mannersB. Driving can show the other part of his personalityC. Driving can bring out his characterD. Driving can show his hidden qualities44. Which of the followings is NOT mentioned as a way against traffic accidents?A. Test drivers every three yearsB. Stricter driving testsC. Build more highwaysD. Raise age limit and lay down safety specifications45. The author's attitude towards the present traffic situation is .A. unsatisfiedB. positiveC. appealingD. unclear四、短文7选5(5选5等)（共5小题；共10分）Public Speaking and Critical ThinkingWhat is critical thinking? To a certain degree, it's a matter of logic(逻辑)—of being able to spot weaknesses in other people's arguments and to avoid them in your own. It also includes related skills such as distinguishing fact from opinion and assessing the soundness of evidence.In the broad sense, critical thinking is focused, organized thinking—the ability to see clearly the relationships among ideas. 46. The greatest thinkers, scientists, and inventors have often taken information that was readily available and put it together differently to produce new ideas. That, too, is critical thinking.47. As the class goes on, for example, you will probably spend a good deal of time organizing your speeches. While this may seem like a purely mechanical(机械的) exercise, it is closely connected with critical thinking. If the structure of your speech is loose and confusing, chances are that your thinking is also disordered and confusing. If, on the other hand, the structure is clear, there is a good chance your thinking is too. Organizing a speech is not just a matter of arranging the ideas you already have. 48.What is true of organization is true of many aspects of public speaking. 49. As you work on expressing your ideas in clear, accurate language, you will improve your ability to think clearly and accurately. 50. As you learn to listen critically to speeches in class, you will be better able to assess the ideas of speakers in a variety of situations.If you take full advantage of your speech class, you will be able to develop your skills as a critical thinker in many circumstances. This is one reason public speaking has been regarded as a vital part of education since the days of ancient Greece.A. Rather, it is an important part of shaping the ideas themselves.B. This may seem like a lot of time, but the rewards are well worth it.C. It may also help you to know that there is no such thing as a perfect speech.D. It has often been said that there are few new ideas in the world, only reorganized ideas.E. If you are wondering what this has to do with your public speaking class, the answer is quite a lot.F. The skills you learn in your speech class can help you become a more effective thinker in a number of ways.G. As you study the role of evidence and reasoning in speech-making, you will see how they can be used in other forms of communication as well.五、翻译(根据中文提示完成句子)（共10小题；共10分）51. 他是个很谨慎的人，坚持要求在吃任何药之前咨询医生。
