Stop三、阅读理解ACallaghan, the father of a teenage daughter, Emma, couldn't understand why he had developed a disease which normally affects men twice his age. A routine CT scan showed a tumor growing on his kidney (肾)．“I was by myself，”Callaghan recalls. “I thought it was a kidney stone. I was in the doctor's office for about 45 minutes that day and I don't remember anything more than one minute of it. The average life span for someone who has my condition is 12 months.” He will take pills every day, possibly for the rest of his life.Callaghan began finding hope in a small act of love for Emma: handwriting notes of love on a napkin (餐巾纸) to place in her lunch box; nothing extraordinary or life-changing, just some words of encouragement for Emma to think of during the day. His numbered days meant numbered napkins. “The reason I started writing notes to her is that I wanted to matter in her life，”said Callaghan. “I see so many working parents today where they kind of give up a lot of their parenting. I wanted Emma to be able to look at me at whatever age she was and say ‘My dad loves me. I need his advice, I need his love and I trust that my dad's going to be there.’”But what started out as a father's way of showing his daughter his love quickly grew. His idea to share his inspirational napkin messages with friends and family on the Internet sparked(触发) a book. His new book Napkin Notes shares each message he's ever sent to his daughter as well as more about his brave battle with cancer and life lessons he hopes Emma and maybe even grown readers can learn.Now Callaghan is still fighting for his life. “The act inspires me just as much as I hope it inspires my daughter，”said Callaghan.26. Which of the following does Callaghan disapprove of when he was diagnosed with cancer?A. He was determined and got well prepared for the fatal disease.B. He wondered why he could develop the cancer at so young an age.C. He felt completely scared because he was alone at the doctor's office.D. He forgot everything about the regular scan at the office, more or less.27. According to the passage, Callaghan's new book Napkin Notes ________．A. was lacking in what he did to struggle against cancerB. was intended to set a good example to other patientsC. was supposed to earn some money for his daughterD. was inspired from what he did to encourage Emma28. What would be the best title for the passage?A. Napkin Notes of LoveB. A Moving StoryC. Life Against CancerD. An Inspiring BookBA group of brave tourists became the first visitors to cross a new 590-foot-high glass-bottomed suspension bridge in China. This special structure, the first of its kind in the world, is situated in the province of Hunan.Images have shown online showing the visitors gripped with fear and frozen in awe while standing on the see-through walkway. One female tourist is seen holding the handrail tightly and had to be dragged along by her friend.The bridge had previously been a wooden one that linked two peaks of Stone Buddha Mountain in Shiniuzhai Geopark but is now a 984-foot-long glass walkway. Part of the bridge had already been replaced with glass in 2014, attracting groups of fearless tourists. However, 11 engineers have been working on the bridge over the last few months to replace all the wooden parts with glass, transforming the bridge into the world's first glassbottomed suspension bridge.According to reports, several visitors were so terrified that they could barely move. Some were seen holding on to each other as well as to the railings as they made the crossing. Many people were filled with fear as they tried not to look down to the steep drop below. The bridge was said to move from side to side slightly when people walked across it, making people feel even more frightened. However, as part of the scenic site, it also offered incredible views over the geopark and the landscape below. The amazing construction has already been named “hero bridge”because of the amount of courage required to cross it.Those worried about the safety of the bridge can rest easy. The glass forming the footpath are said to be 25 times stronger than regular window glass. They're also created to stay in shape and withstand impact although special footwear has been issued to visitors.29. What is the main idea of Paragraph 2?A. The history of the glass bridge.B. The reason why the bridge was built.C. The safety of the glass bridge.D. The wooden bridge should be changed.30. What made traveling through the bridge more fearful?A. The wooden parts with glass.B. The way people walk on it.C. The shaking of the bridge.D. The great landscape below.31. Why is the bridge called “hero bridge”？A. Because only courageous people can cross it.B. Because the bridge was built by brave people.C. Because the bridge doesn't have the railings.D. Because people are full of courage when on it.32. What measure did people take to make the bridge safe?A. They used regular window glass.B. They created strong glass in shape.C. They gave glass special footwear.D. They made construction special.四、任务型阅读请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。

必修一第二单元古代希腊罗马的政治制度一、选择题1. 《左传》有云：“昔周公、大公股肱周室，夹辅成王。
成王劳之，而赐之盟，曰：世世子孙无相害也。
载在盟府，大师职之。
”材料表明A. 周天子与诸侯王关系近乎平等B. “礼崩乐坏”的局面开始出现C. 诸侯之间通过盟约来维系和平D. 等级森严的官僚政治已经确立【答案】C【解析】试题分析：本题主要考查宗法制。
依据材料“昔周公、大公股肱周室，夹辅成王。
成王劳之，而赐之盟，曰：世世子孙无相害也”可知，西周加强统治集团内部的稳定与团结，实行分封制，诸侯之间通过盟约来维系和平，故C项正确；材料“成王劳之，而赐之盟”体现了周王和诸侯王之间的关系是不平等的，周王是天下共主，故A项错误；材料反映的是西周初年，分封制度刚刚建立的状况，故B项错误；官僚体制是秦朝统一六国后实施的，故D项错误。
所以答案选C。
考点：古代中国的政治制度·夏、商、周的政治制度·分封制【名师点睛】分封制作用：①周人的势力范围扩大；②确立了周王天下共主的地位，巩固了统治；③分封制使西周贵族集团形成了“周王—诸侯—卿、大夫—士”的等级序列。
2. 据《大唐语林》记载，某人请求玄宗开恩帮女婿王某科举及第，玄宗答应。
负责科举的礼部侍郎将皇帝钦点王某情况报告宰相。
宰相说：“科举是为国家取才大典，怎么能凭皇帝一句话，就把功名与人？”玄宗只好取消成命。
这则记载表明A. 礼部与宰相共管科举B. 相权对皇权有制约性C. 科举制度具有公平性D. 科考不受皇权的干预【答案】B【解析】试题分析：本题考查从汉到元政治制度的演变。
依据所学知识可知，礼部负责科举考试的组织工作，故A项错误；材料信息“玄宗答应开恩帮女婿王某科举及第，宰相反对，玄宗只好取消成命”说明了皇权一定程度受到了相权的制约，故B项正确；科举制度具有相对公平性，故C项错误；根据所学知识可知，科考不受皇权的干预不符合史实，故D项错误。
3. 公元前451—450年，雅典通过了伯里克利所提议的法律，规定只有父母双方皆是雅典公民的人，才能成为雅典公民。

An American professor discovered this difference while teaching a class in a Brazilian(巴西的) university. The two-hour class was scheduled to begin at 10 a．m. and end at 12 a．m. On the first day, when the professor arrived on time, no one was in the classroom. Many students came after 10 a．m. Several arrived after 10：30 a．m. Two students came after 11 a．m. Although all the students greeted the professor as they arrived, few apologized for their lateness. Were these students being rude? He decided to study the students' behaviour.The professor talked to American and Brazilian students about lateness in both informal and a formal situation: at a lunch with a friend and in a university calls, respectively. He gave them an example and asked them how they would react. If they had a lunch appointment with a friend, the average American student showed clearly lateness as 19 minutes after agreed time. On the other hand, the average Brazilian student left the friend late after 33 minutes.In an American university, students are expected to arrive at the appointed hour, while, in Brazil, neither the teacher nor the students always arrive at the appointed hour. Classes not only begin at the scheduled time in the United States, but also end at the scheduled time. In the Brazilian class, only a few students left the class at 12：00; many remained past 12：30 to discuss the class and ask more questions. Arrived late may not be very important in Brazilian, neither isstaying late.31. Why did the professor study the Brazilian students' behaviour?A. He felt puzzled at the students' being late.B. He felt angry at the students' rudeness.C. He wanted to make the students come on time later.D. He wanted to collect data for one of his studies.32. It can be inferred from the professor's study of lateness in the informal situation that ________.A.

However, this issue(问题) frequently causes heated debate.Some people say that classical music is associated only with old people. For example, if you look at the audience at a classical concert, the majority is over the age of fifty.Others say it is more popular than we first imagine. Many young people listen to classical music without realizing. It is often used in films and advertisements. For example, a famous piece of classical music was used as the theme music for the 1990 World Cup. Not many people could have given its name, but millions enjoyed it.Also, some people point out that young people produce new music based on classical ideas; for example, it is said that rap(说唱) music was invented by a classical musician in 1912, but it is now used by young people in pop music.However, young people point to the fact that classical music has been outstripped(超越) by technology. To play a classical instrument, such as a violin, you need to study hard and practise for hours. Nowadays, you don't need to get aching arms from practising. A teenager can write and make music using a computer program in the comfort of their own bedroom.A final point to bear in mind is that the term “classical music”is used to refer to a great variety of music, from jazz to pieces for large orchestras(管弦乐队). This makes it even more difficult to say whether classical music is relevant to young people.So, it may be only a minority of young people who play classical instruments, but when it comes to enjoying classical music, it depends on the piece of music. It may be more relevant to young people in the modern world than they realize!Title: Classical Music五、书面表达你校外籍教师Ernesto和Stasi暑假期间准备在本市开一家西餐店，要找若干名高中生免费打工。

Eating unhealthy snacks at your desk makes you pile on almost half a stone a year, a survey has revealed. The waistlines of women suffer the most, with the average female putting on 6lb 3oz—the equivalent of a whole dress size—while men see their weight increase by 5lb 2oz.The report into our eating habits found that, on average, we eat at least two snacks a day, with 30 percent of us tucking into three or more. Women admit eating more than men, with a further 13 percent of ladies scoffing four or more snacks a day. The research, by The Village Bakery, found biscuits are the most common vice, with 42 percent regularly opening a pack, closely followed by chocolate (38 percent), crisps (32 percent) and cakes (13 percent)．And office workers are worse than most. Cakes and biscuits brought into work by colleagues are one of the main temptations office staff give in to. In addition, 33 percent admit reaching for nibbles to cope with stress and 22 percent say they need a sugar rush to perk them up in the afternoon.Simon Staddon, of The Village Bakery, said：“We were aware timepoor office workers can find it difficult to easily access a nutritional lunch. But we were really shocked by the extent to which ‘quick fix’ lun ches are affecting weight gain and general well-being. Popular mid-afternoon pick-me-ups such as biscuits, chocolate and cakes are high in calories, fat and full of sugar, all of which affect your blood sugar levels and ultimately lead to weight gain.”The survey of 2，000 British men and women suggests we are often ashamed of our unhealthy eating. 24 percent of Britons admit lying about how many snacks they eat with 33 percent of women lying, compared to 20 percent of men. Unfortunately, it’s as if we are n ot likely to do anything positive to counteract the sweet treats.31. According to the passage, women usually put weight on first ________．A. on the faceB. on the legsC. on the feetD. in the middle32. What’s the main reason of eating snacks in office?A. Colleagues eat them to save money.B. Staff use them to cope with their lunches.C. Colleagues often bring them to office.D. Bosses invite staff to eat them.33. Why do office workers eat a “quick fix” lunch?A. Because it has much of nutrition.B. Because it has little effect on weight gain.C. Because it has little effect on general well-being.D. Because they have short time to have their lunches.34. It can be inferred that British women are________.A. less likely to lie on snacks than menB. more likely to lie on snacks than menC. more ashamed of eating snacks than menD. less ashamed of eating snacks than men35. What does the underlined word “counteract” in Paragraph 5 possibly mean?A. Act against.B. Appeal to.C. Copy out.D. Get in.BAre you having difficulty falling asleep? Try drinking a glass of warm milk. If that doesn’t work, listen to soft, beautiful music. Still no luck? Try thinking about sheep jumping over a fence. If you are still awake, take a sleeping pill. But people who take pills often become dependent on the drugs. So you lie awake knowing that the new workday will soon arrive. If you have been in such condition for at least one month, you may have primary insomnia(失眠症)．A new study has found that you might fall asleep more quickly and stay asleep longer if you try “cerebral hypothermia”. It is not a complex medical process. It just means cooling down your brain. Eric Nofzinger and Daniel Buysse from the University of Pittsburgh Medical School led the study. They examined twelve people who had sleeping problems. Twelve others had no sleep problems. Each of them wore a soft plastic cap on their head at bedtime.The caps had tubes inside filled with water. The researchers moved the water through the tubes and then changed the temperature of the water. Other studies showed that people who had sleeping problems often had more chemical reactions in the front of their brain. The researchers thought cooling down the brain might help.On the first two nights of testing, the patients wore caps with no water. On the next two nights, the caps were worn, but the water was not cooled. Then the researchers cooled the water a little for another two nights. On the final two nights of the study, the temperature of the water was made much cooler.The researchers found that the water caps didn’t help the patients until the temperature was about 14℃. Most of the patients fell asleep faster and slept better when the coolest water was moving around their heads.Dr Nofzinger and Dr Buysse noted that this was only the beginning of the brain temperature study. But they believed they had discovered something important that needed more research.36. The first paragraph is written to ________．A. explain how serious insomnia isB. bring forward the topic of the passageC. tell us the causes of sleeping problemsD. tell us the danger of having sleeping problems37. From the passage we know that “cerebral hypothermia” is actually ________．A. a complex medical processB. a psychological treatmentC. a simple physical treatmentD. a difficult scientific theory38. In the study, researchers helped people fall asleep faster through ________．A. increasing chemical reactions in the front of their brainB. making them feel safe with a cap on their headC. asking them to drink water to cool downD. lowering the temperature of their brain39. Dr Nofzinger and Dr Buysse seemed to believe that ________．A. their research wouldn’t help people greatlyB. more studies would be needed for their researchC. cooling down people’s brain might be harmfulD. the results of their study would be made use of soon四、任务型阅读Blood donation, also called blood banking, is a wonderful thing to do. It is an easy and direct way to contribute to social work and help the community. It helps to save lives and helps those who are in need of blood due to bad condition or the heavy loss of blood during operations or in accidents.You are able to give or donate blood every three or four months, and it is a great way to make a huge difference to someone’s life and you can always be proud of it after making valuable contributions to society. Blood donation is not a big problem, but you need to keep a few points in mind.Before donating blood, make sure that the ferrum(铁) level in your body is high enough and for that you should take a healthy diet. Do not go for blood donation on an empty stomach. You should follow the correct process so that everything goes well. After having a balanced diet you will feel strong and comfortable to donate blood. Afterwards, you will not feel faint or weak.For required hemoglobin(血红蛋白) in your body, drink lots of juice and other drinks. Fruit juice, such as apple juice is very good for increasing the blood level in your body.For a good blood flow in your body, drink at least 6—7 glasses of water every day.Completely avoid a day before and after giving blood, taking alcohol(酒). Do not smoke half an hour before giving blood.When you are going for blood donation, be relaxed, which helps keep the right blood pressure. During the blood donation activity, take a deep breath and try to calm yourself. Don’t join in some other activities.When you donate blood, you are making the effort to save someone’s life. Blood donation is a very simple and fast process, but you need to take care of yourself after donating blood. Proper care helps to reduce side effects. The following are a few tips that will help you out.Take a rest for 15 minutes after the donation. It helps you to feel relaxed.Eat something and drink juice before leaving the blood donation centre. Make sure that you have meals after donating blood. Smoking should be avoided for one hour after the process. Avoid some activities right away, for example, driving.Finally, be proud of yourself because you have done a great thing in helping to save someone’s life. Blood donation is a very important activity.Title: Blood Donation—an Important ActivityThe (40) _______ of blooddonation ●(41) ________ to social work and the community● Helping those people who suffer the loss of (42) ________● Giving yourself asense of pride(43) ______ the donation ● Take a healthy (44) ________ for a high ferrum level● Drink fruit juice for enough hemoglobin● Drink a t least 6—7 glasses of water daily for a good (45) ______ of blood● (46) ________ takingalcohol and smoking cigarettesDuring the donation● Relax and breathe deeply● Never take (47) ________ in otheractivitiesAfter the donation● Take a rest● Don’t skip (48) ________● Don’t smoke until onehour later● Don’t join in some activities like driving (49) ________五、书面表达读者王彬写信给某杂志“开心”栏目记者Mary，询问怎么才会感到幸福，请根据提示给他写一封回信，主题为How to Be Happy。

She is a headhunter, and had just finished interviewing a candidate but failed to impress him.Then she started to complain about her health problems. One year ago, she began to notice a ringing in her ears. She went to the hospital and was told that her problem might have resulted from stress. The doctor gave her pills for her nerves.At night, she has to listen to loud music to quiet the noise in her head and fall asleep. Her life has become a twopoint routine of work and home. Even while she was vacationing in Thailand, she found herself searching for the right candidate.She suffers from the same workaholic depression as another friend who works for an advertising company. This friend has to work overtime almost every day. If she's lucky, she can leave at 9 p．m.; otherwise it's midnight. For her, working on weekends has become normal. Each time I see her, she seems down.My two friends share something in common: They don't want to escape their misery, believing that if you don't work hard when you are young, you will regret it. That may be true, but there are limits. If every day you wake up feeling down, then it may be time to move on.As important as finding a job that you really like, is finding a company with a healthy atmosphere. The right company should lift your spirits and have a team working toward a common goal. As for the employees, they should work hard and play hard. If you can enjoy life, you will have more passion to bring to your work.27. Why did the author's old friend suffer from health problems?A. Because of stress from work.B. Because she ate too much.C. Because of the loud noise in her workplace.D. Because she failed to impress a candidate.28. One thing that the author's two friends share is that ________．A. they both love their workB. they both work extremely hardC. they both work for an advertising companyD. they both take an active part in social activities29. What does the author think important in finding a job?A. Chances to achieve one's goal.B. Chances to learn new things.C. A pleasant working atmosphere.D. A good boss and a large salary.BIf you feel sleepy every morning, don't blame yourself. Your work schedule could be to blame.A recent research shows that, for many of us, our work schedules do not agree with our natural body clocks—and experts are urging employers to take notice.“When work schedules agree with people's natural sleep patterns, they produce higher quality and more creative work because they are more focused, less stressed and generally healthier. The opposite is also true—when employees are sleep deprived, they are more likely to make major mistakes and suffer from workplace injuries，”said Christopher Barnes, a management professor from the University of Washington.“But it's not just about the amount of sleep you get. Whether you can be productive at 8 a．m. depends on your own body. Human beings each have an internal body clock，”said Till Roenneberg, a professor at LudwigMaximilian University in Munich. And that clock can differ greatly depending on the person.“It's like feet，”said Roenneberg. “Some people are born with big feet and some with small feet, but most people are somewhere in the middl e.”Many companies start the work day at 8 a．m. or 9 a．m., putting their work schedules in disagreement with their employees' body clock. That mismatch, along with the pressure from work at all hours of the day and night, means that many people suffer from “social jetlag”. In other words, their bodies are always in the wrong time zone. He estimates that more than 70% of people get up earlier than they should.“There is an old saying that sleep is for the weak，”said Roenneberg. “But I do feel like it doesn't help to have shortened sleep.”30. According to the author, many people feel sleepy in the morning because________．A. they start to work too earlyB. they are not in good healthC. they have no interest in their workD. they stay up too late the night before31. What does Christopher Barnes mainly tell us?A. The influences of lack of sleep.B. The possible causes of poor sleep.C. The useful ways to improve our sleep.D. The connection between sleep and work performance.32. By mentioning people's feet, Roenneberg intends to tell us ________．A. people are born with feet of different sizesB. people's body clocks differ from person to personC. it is the most important to wear shoes of the right sizeD. it is most important to obey our natural body clocks33. Which of the following does the author agree to?A. Sleep is for the weak.B. The early bird catches the worm.C. Plenty of sleep contributes to good work.D. The more you sleep, the less work you can do.四、任务型阅读Anything that poses a challenge or a threat to our wellbeing is a stress. Some stresses get you going and they are good for you—without any stress at all many say our lives would be boring and would probably feel pointless. However, when the stresses undermine both our mental and physical health they are bad. Here we shall be focusing on stress that is bad for you.Stress is the feeling we have when under pressure, while stressors are the things we respond to in our environment.Examples of stressors are noises, unpleasant people, a speeding car, or even going out on a first date. Generally (but not always), the more stressors we experience, the more stressed we feel.When we are stressed the following happens：Blood pressure rises.Breathing becomes more rapid.Heart rate (pulse) rises.Muscles become tense.We do not sleep (heightened state of alertness)．Most of us have varying interpretations of what stress is about and what matters. Some of us focus on what happens to us, such as breaking a bone or getting a promotion, while others think more about the event itself. How you see that stressful event will be the largest single factor that impacts on your physical and mental health. Your interpretation of events and challenges in life may decide whether they are invigorating or harmful for you.There are three broad methods you can follow to treat stress.Self help for treating stressExercise has been proven to have a beneficial effect on a person's mental and physical state. For many people exercise is an extremely useful stress buster.Alcohol and drugs will not help you manage your stress better. Either stop consuming them completely, or cut down.If your consumption of coffee and other drinks which contain caffeine is high, cut down.Eat plenty of fruit and vegetables. Make sure you have a healthy and balanced diet.Talk to you family, friends, work colleagues and your boss. Express your thoughts and worries.Stress management techniquesStress management can help you to keep away from the source of stress, change the way you view a stressful event, and lower the impact that stress might have on your body. Stress management therapy will have the objective of pursuing one or more of these approaches.MedicinesDoctors will not usually prescribe medications for coping with stress, unless the patient has an underlying illness, such as depression or some type of anxiety. If that is the case, the doctor is actually treating a mental illness. In such cases, an antidepressant may be prescribed. Bear in mind that there is a risk that all the medication will do is mask the stress, rather than help you deal andcope with it.五、 书面表达随着神州十一号成功发射，宇航员景海鹏也为世人瞩目，他是中国第一位3次升入太空的宇航员，以下是他接受记者采访的话语节选和简历。

C解析：在物理学史上，正确认识运动与力的关系并且推翻“力是维持运动的原因”的物理学家和建立惯性定律的物理学家分别是伽利略和牛顿，选项C正确．2. A解析：由图可知AB的长度为2 cm，即0.02 m，曝光时间为11 000s，所以AB段的平均速度的大小为v＝xt＝20 m/s，由于时间极短，故A点对应时刻的瞬时速度近似为20m/s，由自由落体的速度—位移的关系式v2＝2gh，可得h＝v22g＝20 m，选项A正确．3. C解析：物体受三个力：重力和两个拉力，重物C缓慢竖直上升时三力平衡，合力为零，则知两个拉力的合力与重力大小相等，所以重物C所受的合外力不变，两个拉力合力一定，而两个拉力的夹角不断增大，故拉力不断增大，选项C正确．4. D解析：设两小球带电荷量分别为Q和7Q，当两相同金属小球带异种电荷时，两者相互接触后再放回原来的位置上，它们的电荷量变为3Q和3Q，由库仑定律可得F＝k Q1Q2r2，故库仑力是原来的97，选项D正确．5. B解析：物体受到重力、支持力及摩擦力而做匀速直线运动，由共点力的平衡条件可知物体所受合力为零，选项A错误；物体受到的摩擦力沿斜面向上，因物体受三个力而处于平衡，故重力与支持力的合力的方向一定与摩擦力方向相反，故二力的合力一定沿斜面向下，选项B正确；在垂直于斜面方向上，物体受到的合力应为零，故支持力应等于重力垂直于斜面的分力，即支持力小于重力，选项C错误；滑动摩擦力f＝μF N，故摩擦力与下滑速度无关，只与正压力及动摩擦因数有关，选项D错误．6. D解析：在A点将小球以小于v的速度水平抛出，则小球将被挡板挡住，不能落到挡板和B点之间，选项A错误；在A点将小球以大于v的速度水平抛出，则小球将越过挡板落到B点的右侧，选项B错误；在A点正下方某位置将小球以小于v的速度水平抛出，则小球将被挡板挡住，不能落到挡板和B点之间，选项C错误；在A点正上方某位置将小球以小于v的速度水平抛出，则小球能到达挡板上端，速度方向与竖直方向的夹角满足tanθ＝v2gh，因v变小，h变大，故θ减小，则小球的落地点位于挡板和B点之间，选项D正确．7. B解析：由题意可知，船相对水的速度为v，其航线恰好垂直于河岸，当水流速度稍有增大，为保持航线不变，且准时到达对岸，如图所示，有v1＝vcos α，可知要减小α角，增大船速v，选项B正确．8. D解析：滑雪运动员的速率不变，运动员下滑过程中的加速度是向心加速度，其大小不变，方向始终指向圆心，选项A错误；运动员受三个力作用做匀速圆周运动，运动员所受合外力大小不变，选项B、C错误；运动员下滑过程中，对山坡的压力逐渐增大，滑动摩擦力逐渐增大，与雪面的动摩擦因数变小，选项D正确．9. B解析：老鹰沿虚线斜向下减速飞行，加速度沿虚线向上，故合力F沿虚线向上；老鹰受重力和空气对其作用力，根据三角形定则可知选项B正确．10. B解析：小球在水平方向不受力，所以做匀速直线运动，选项A错误；小球运动过程中只受重力，根据牛顿第二定律可知小球的加速度不变，小球做匀变速运动，选项B 正确；最高点是小球运动的最高点，小球在最高点速度沿水平方向，不为零，选项C 错误；小球在最高点速度沿水平方向，而重力是竖直方向，瞬时功率P ＝mgvcos θ＝0，选项D 错误．11. D 解析：a 点与c 点是同缘传动，线速度相等，因转动半径不等，由T ＝2πr v知，选项C 错误；根据v ＝rω，a 、c 两点转动角速度不同，又由于b 、c 两点的角速度相同，故a 点和b 点的角速度不等，选项B 错误；a 点和b 点转动半径相等，转动角速度不等，故线速度不等，选项A 错误；c 点和d 点是共轴转动，角速度相同，根据a ＝rω2得，d 点的向心加速度是c 点的2倍，根据a ＝v 2r知，a 的向心加速度是c 的2倍，所以a 、d 两点的向心加速度大小相等，选项D 正确．12. D 解析：在这段时间内处于失重状态，是由于她对体重计的压力变小了，而她的重力没有改变，选项A 错误；晓敏对体重计的压力与体重计对晓敏的支持力是作用力与反作用力的关系，大小相等，选项B 错误；人处于失重状态，加速度向下，运动方向可能向上减速，也可能向下加速，选项C 错误；以竖直向下为正方向，有mg －F ＝ma ，解得a ＝g 5，方向竖直向下，选项D 正确．13. D 解析： 0～t 2时间内摩托车的速度比飞机大，摩托车在前，两者间距增大，t 2时刻后飞机的速度比摩托车大，两者间距减小，所以在t 2时刻，距离最大，选项A 、B 错误；根据图线与时间轴围成的面积表示位移知，t 3时刻飞机的位移比摩托车大，所以在t 3时刻前两者相遇，飞机速度没有达到最大速度2v 0，选项C 错误，D 正确．14. A 解析：重力做功的功率就是P ＝mgv ，这里的v 是指竖直的分速度，A 由静止释放，所以A 一开始的竖直速度也必然为零，最后运动到a 点的时候，由于此时的切线是水平的，所以此时的竖直速度也是零，但是在这个过程当中是有竖直分速度的，竖直速度是从无到有再到无的变化过程，也就是一个先变大后变小的过程，所以重力做功的功率也是先增大后减小的过程，选项A 正确；A 球由c 点下滑到a 点的过程中，沿绳子方向的速度是一样的，在A 滑下去一段过程后，此时的绳子与圆的切线不重合，而是类似于圆的一根弦线而存在，所以此时两个物体的速度不相同，选项B 、C 错误；若A 球恰好能沿圆弧轨道下滑到a 点，此时两小球速度均为零，根据动能定理得m 1gR(1－cos 60°)＝m 2gR ，解得m 1＝2m 2，选项D 错误．15. C 解析：设地球半径为R ，密度为ρ，则地球对卫星的万有引力提供卫星圆周运动的向心力，有G m·43πR 3ρR 2＝m 4π2T 2R ，可得G ＝3πρT 2，设某行星的半径为r ，则其同步卫星的半径为4r ，周期为T′，据万有引力提供圆周运动向心力，有G Mm （4r ）2＝m 4π2T ′2·4r ，即3πρT 2·ρ43πr 316r 2＝4r 4π2T ′2，解得T′＝8T ，选项C 正确． 16. C 解析：C 为同步卫星，即角速度和地球自转角速度相同，离地高到大于地球半径，根据公式G Mm r 2＝mω2r 可得ω＝GM r 3，即ωC <ωB ，选项A 错误；根据公式G Mm r2＝m v 2r 可得v ＝GM r，即运动半径越大，卫星的线速度越小，故v C <v B ，选项B 错误；根据公式a ＝ω2r ，可得物体A 随地球自转的向心加速度小于卫星C 的向心加速度，选项C 正确；C 是同步卫星，和地球自转周期相同，选项D 错误．17. D 解析：光滑斜面，只有重力做功，根据动能定理mgh ＝12mv 2，即速度v ＝2gh ，小物块滑到斜面底端的速度大小相同，但是速度方向不同，选项A 错误；滑到斜面底端的重力的瞬时功率为P ＝mgvcos θ，由于速度方向与重力方向的夹角θ不同，所以滑到斜面底端的重力的瞬时功率不同，选项C 错误；小物块滑到斜面底端为匀加速直线运动，加速度a ＝gsin α，位移x ＝h sin α＝12at 2，可得运动时间t ＝2h gsin 2α，两个小球对应的斜面倾角不同，运动时间不同，选项B 错误；两个小球在斜面顶端动能相等都等于0，重力势能相等，滑动过程机械能守恒，所以滑到底端机械能依然相同，选项D 正确．18. B 解析：图A 是正点电荷周围电场线的分布图，M 、N 两点的场强大小相同，方向不同；图B 是匀强电场，M 、N 两点场强大小相同，方向相同；图C 是负点电荷周围电场线的分布图，M 、N 两点的场强大小不同，由点电荷的场强公式可知，M 点的场强大于N 点的场强，方向相同；图D 中由电场线的疏密程度知N 点的场强大于M 点的场强．选项B 正确．19. B 解析：公式E ＝F q采用比值定义法，E 反映电场本身的强弱和方向，与试探电荷在电场中该点所受的电场力F 和电荷量q 无关，选项A 错误；由公式E ＝kQ r2可知，Q 是场源电荷，电场强度E 的大小与Q 成正比，与r 的平方成反比，选项B 正确；公式U ＝Ed 中d 是两点沿电场方向的距离，所以在匀强电场中，任意两点间的电势差与这两点间沿电场方向的距离成正比，而不是与任意距离成正比，选项C 错误；公式C ＝Q U采用比值定义法，C 反映电容器容纳电荷的本领，与Q 、U 无关，选项D 错误．20. C 解析：球B 运动到最高点时，球B 对杆恰好无作用力，即重力恰好提供向心力，有mg ＝m v 22L，解得v ＝2gL ，选项A 、B 错误，C 正确；因为AB 同轴转动，B 的半径是A 的两倍，有v B ＝2v A ，即v A ＝122gL ，选项D 错误． 21. (1) ① BCD ② x 1x 2(2) ① 0.4 ② 3 ③mg M mg M ＋m 解析：(1) ① 本实验采用控制变量法，要求两个车的质量相同，且必须远大于砝码和砝码盘的总质量，选项A 错误，C 正确；使细线与轨道平行是为了减小摩擦，选项B 正确；为了保证砝码和砝码盘的总重力作为小车的合外力，就必须平衡摩擦力，选项D 正确．② 根据x ＝12at 2，可得a 1a 2＝x 1x 2. (2) ① 根据Δx ＝aT 2，得a ＝Δx T2＝0.4 m/s 2. ② 如果遗漏平衡摩擦力这一步骤，当力比较小的时候，小车不能运动，没有加速度，所以图线3符合要求．③ 根据牛顿第二定律，当满足砝码和砝码盘的总质量远小于小车的质量时，a 1＝mg M ，为一条过原点的直线；如果不能满足，则mg －F ＝ma 2，F ＝Ma 2，联立可得a 2＝mg M ＋m. 22. 解：(1) 由题图b 可知，甲车的加速度大小a 甲＝v 0－v t 1＝40－10t 1＝30t 1乙车的加速度大小a 乙＝v －0t 1＝10t 1由m 甲a 甲＝m 乙a 乙 解得 m 甲m 乙＝13 (2) 在t 1时刻，甲、乙两车的速度相等，均为v ＝10 m/s ，此时两车相距最近． 对乙车有：v ＝a 乙t 1对甲车有：v ＝a 甲(0.4－t 1)解得t 1＝0.3 s到速度相等时甲车的位移s 甲＝v 0＋v 2t 1＝40＋102×0.3 m ＝7.5 m 乙车的位移s 乙＝v 2t 1＝102×0.3 m ＝1.5 m 两车相距最近的距离为s min ＝s 0＋s 乙－s 甲＝4.0 m23. 解：(1) 由匀变速直线运动的公式s ＝12at 2 得a ＝2s t 2 (2) 设连接杆对拖拉机的拉力为T ，由牛顿第二定律得F －kMg －Tcos θ＝Ma 解得拖拉机对连接杆的拉力大小为T ＝1cos θ⎣⎡⎦⎤F －M ⎝⎛⎭⎫kg ＋2s t 2 根据牛顿第三定律得T′＝1cos θ⎣⎡⎦⎤F －M ⎝⎛⎭⎫kg ＋2s t 2 (3)拖拉机对耙做的功 W ＝T′s cos θ＝⎣⎡⎦⎤F －M ⎝⎛⎫kg ＋2s t 2s 24. 解：(1) 物块摆动过程中机械能守恒，有mg(l －lcos 60°)＝12mv 2 解得v ＝5 m/s物块运动到悬点正下方时，有F －mg ＝m v 2l解得F ＝10 N(2) 物块在小车上表面水平部分运动时，加速度大小a 1＝μmg m＝2 m/s 2 位移大小x 1＝vt －12a 1t 2＝4 m 小车的加速度大小a 2＝μmg M＝0.5 m/s 2 位移大小x 2＝12a 2t 2＝0.25 m 小车上表面水平部分长度Δx ＝x 1－x 2＝3.75 m(3) 物块脱离小车上表面水平部分时的速度v 1＝v －a 1t ＝3 m/s小车的速度v 2＝a 2t ＝0.5 m/s物块离开小车后做平抛运动，则h ＝12gt 21解得t 1＝0.6 st 1时间内，物块的位移大小x 1′＝v 1t 1＝1.8 m小车的位移大小x 2′＝v 2t 1＝0.3 m斜面水平长度x ＝x 1′－x 2′＝1.5 m斜面倾角的正切值tan θ＝h x＝1.2 25. 解：(1) 因为四驱车到达C 点的速度大小为5 m/s ，B 到C 的过程为平抛运动，故其水平分速度即为到达B 点的速度v B ＝v C cos53°＝3 m/s(2) 到B 点时速度恰达到最大值，所以AB 间阻力f ＝Pv max ＝P v B ＝3 N 由动能定理，从A 到B 有Pt －fL ＝12mv 2B解得t ＝2.5 s(3) 由到F 点时轨道对它的压力恰为零知mg ＝mv 2F Rv F ＝2 m/s 则从C 到F ，由动能定理得－mgR(1＋cos53°)－W f ＝12mv 2F －12mv 2C 解得W f ＝4.1 J。
