山东省青岛市西海岸新区胶南第一高级中学2018届高三上学期第二次月考理科综合化学试题1. 化学与生活密切相关，下列说法错误的是（）A. “神州七号”的防护层中含聚四氟乙烯，制备聚四氟乙烯的单体属于不饱和烃B. 聚乳酸是常用的微生物降解高分子：合成纤维、人造纤维统称化学纤维C. 铁是生活中常用的金属，在一些反应中可作催化剂D. 回收地沟油制造生物柴油符合环境保护的要求【答案】A【解析】A. “神州七号”的防护层中含聚四氟乙烯，制备聚四氟乙烯的单体为四氟乙烯，属于不饱和卤代烃，A不正确；B. 聚乳酸是常用的微生物降解高分子，合成纤维、人造纤维统称化学纤维（以区别于天然纤维），B正确；C. 铁是生活中常用的金属，在一些反应中可作催化剂，如合成氨工业，C正确；D. 回收地沟油制造生物柴油，既变废为宝又减少污染，所以符合环境保护的要求，D正确。

本题选A。

2. 在通风橱中进行下列实验：下列说法不正确的是（）A. Ⅰ中气体由无色变红棕色的化学方程式：2NO+O2═2NO2B. Ⅱ中的现象说明Fe表面形成致密的氧化层，阻止Fe进一步反应C. 对此Ⅰ、Ⅱ中现象，说明稀HNO3的氧化性强于浓HNO3D. 针对Ⅲ中现象，在Fe、Cu之间连接电流计，可判断Fe是否被氧化【答案】C【解析】试题分析：A、Ⅰ中由于稀硝酸有强的氧化性，与铁发生氧化还原反应，硝酸得到电子被还原变为NO，气体为无色，当遇到空气时，发生反应：2NO+O2=2NO2，气体变为红棕色的NO2，A正确；B、在Ⅱ中浓硝酸有强的氧化性，在室温下遇铁、铝会使金属表面氧化产生一层氧化物薄膜，对内层金属起保护作用，从而防止金属的进一步反应，即发生钝化现象，因此不能进一步反应，这恰好说明浓硝酸的氧化性比稀硝酸强，因此B正确；C、根据以上分析可知，C错误；D、Ⅲ中将金属铜放入浓硝酸中，Fe、Cu及浓硝酸构成原电池，由于铁在浓硝酸中发生发生钝化，因此铁为原电池的正极，铜为负极，失去电子被氧化变为Cu2+，在正极上溶液中的NO3-得到电子被还原为NO2气体，因此会看到有红棕色的气体产生。

When I arrived to collect, I found the building was dark except for a single light in a ground floor window.I walked to the door and knocked, “Just a minute,” answered a weak, elder ly voice.After a long pause, the door opened. A small woman in her eighties stood before me. By her side was a small suitcase.I took the suitcase to the car, and then returned to help the woman. She took my arm and we walked slowly toward the car.She k ept thanking me for my kindness. “It’s nothing,” I told her. “I just try to treat my passengers the way I would want my mother treated.”“Oh, you’re such a good man.” She said. When we got into the taxi, she gave me an address, and then asked, “Could you drive through downtown?”“It’s not the shortest way,” I answered quickly.“Oh, I’m in no hurry,” she said. “I’m on my way to a hospice(临终医院). I don’t have any family left. The doctor says I don’t have very long.”I quietly reached over and shut off the meter(计价器).For the next two hours, we drove through the city. She showed me the building where she had once worked, the neighborhood where she had lived, and the furniture shop that had oncebeen a ballroom where she had gone dancing as a girl.Sometimes she’d ask me to slow down in front of a particular building and would sit staring into the darkness, saying nothing.At dawn, she suddenly said,” I’m tired. Let’s go now.”We drove in silence to the address she had given me.“How much do I owe you?” she asked.“Nothing.” I said.“You have to make a living,” she answered. “Oh, there are other passengers,” I answered.Almost without thinking, I bent and gave her a hug. She held onto e tightly. Our hug ended with her remark, “You gave an old woman a little moment of joy.”41. The old woman chose to ride through the city in order to ______.A. show she was familiar with the cityB. see some places for the last timeC. let the driver earn more moneyD. reach the destination on time42. The taxi driver did not charge the old woman because he ______.A. wanted to do her a favorB. shut off the meter by mistakeC. had received her payment in advanceD. was in a hurry to take other passengers43. What can we learn from the story?A. Giving is always a pleasure.B. People should respect each other.C. An act of kindness can bring people great joy.D. People should learn to appreciate others’ concern.BDomestic (驯养的) horses now pull ploughs, race in the Kentucky Derby, and carry police. But early horses weren’t tame (驯服的) enough to perform these kinds of tasks. Scientists think the first interactions humans had with horses were far different from those today.Thousands of years ago, people killed the wild horses that lived around them for food. Over time, people began to catch the animals and raise them. This was the first step in domestication.As people began to tame and ride horses, they chose to keep those animals that had more desirable characteristics. For example, people may have chosen to keep horses that had a gentle personality so they could be ridden more easily. People who used horses to pull heavy loads would have chosen to keep stronger animals. Characteristics like strength are partly controlled by the animals’ genes. So as the domesticated horses reproduced, t hey passed the characteristics on to their young. Each new generation of houses would show more of these chosen characteristics.Modern day horse breeds come in a wide variety of shapes and sizes. This variety didn’t exist in the horse population before domestication. The Shetland horse is one of the smallest breeds—typically reaching only one meter tall. With short, strong legs, the animals were bred to pull coal out of mine shafts (矿井) with low ceilings. Huge horses like the Clydesdale came on the scene around 1700. People bred these heavy, tall horses to pull large vehicles used for carrying heavy loads.The domestication of horses has had great effects on societies. For example, horse were important tools in the advancement of modern agriculture. Using them to pull ploughs and carry heavy loads allowed people to farm more efficiently. Before they were able to ride horses, humans had to cross land on foot. Riding horses allowed people to travel far greater distance in much less time. That encouraged populations living in different areas to interact with one another. The new from of rapid transportation helped cultures spread around the world.44. Before domestication horses were ______.A. caught for sportsB. hunted for foodC. made to pull ploughsD. used to carry people45. The author uses the Shetland horse as an example to show ______.A. it is smaller than the Clydesdale horseB. horse used to have gentle personalitiesC. some horses have better shaped than othersD. horses were of less variety before domestication46. Horses contributed to the spread of culture by ______.A. carrying heavy loadsB. changing farming methodsC. serving as a means of transportD. advancing agriculture in different areas47. The passage is mainly about _______.A. why humans domesticated horsesB. how humans and horses needed each otherC. why horses came in different shapes and sizesD. how human societies and horses influenced each otherCDear Hamilton,We are fortunate that in such a large, high-pressure office we all get along so well. You are one of the people who keep the social temperature at such a comfortable setting. I don’t know anyone in the office who is better liked than you.You can perhaps help with this. The collection of contributions towards gifts for employees’ personal-life events is becoming a little troubling. Certainly, the group sending of a gift is reasonable now and then. In the past month, however, there have been collections for two baby shower gifts, one wedding shower gift, two wedding gifts, one funeral（葬礼）remembrance, four birthday gifts, and three graduation gifts.It’s not only the collected-from who are growing uncomfortable (and poor), but the collected-for feel uneasy receiving gifts from people who don’t know them outsid e the office, who wouldn’t even recognize their graduating children, their marrying daughters and sons, or their dead relatives.This is basically a kind gesture (and one that people think well of you for), but the practice seems to have become too wide-ranging and feels improper in today’s office setting.Thank you for understanding.48. The underlined word “contributions” probably means ________.A. moneyB. suggestionsC. reportsD. understanding49. Hamilton is expected to _______.A. show more kindness.B. discontinue the present practiceC. quit being the organizer for gift givingD. know more about co-workers’ families50. This is basically a letter of ________.A. apologyB. sympathyC. appreciationD. dissatisfactionDWhen it comes to friends, I desire those who will share my happiness, who possess wings of their own and who will fly with me. I seek friends whose qualities illuminate（照亮）me and train me up for love. It is for these people that I reserve the glowing hours, too good not to share.When I was in the eighth grade, I had a friend. We were shy and “too serious” about our studies when it was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school, but she would come to my house and we would sit down with pencils and paper, and one of us would say:“Let’s start with a train whistle today.” We would sit quietly together and write separate poems or stories that grew out of a train whistle. Then we would read them aloud. At the end of that school year, we, too, were changing into social creatures and the stories and poems stopped.When I lived for a time in London, I had a friend, He was in despair(失望)and I was in despair. But our friendship was based on the idea in each of us that we would be sorry later if we did not explore this great city because we had felt bad at the time. We met every Sunday for five weeks and found many excellent things. We walked until our despairs disappeared and then we parted. We gave London to each other.For almost four years I have had remarkable friend whose imagination illuminates mine. We write long letters in which we often discover our strangest selves. Each of us appears, sometimes in a funny way, in the other’s dreams. She and I agree that, at certain times, we seem to be parts of the same mind. In my most interesting moments, I often think:“Yes, I must tell….”We have never met.It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than the lifetime services of a psychologist（心理学家），who will only fill up the healing（愈合的）silence necessary to those darkest moments in which I would rather be my own best friend.51. In the eighth grade, what the author did before developing proper social behavior was to ______.A. become serious about her studyB. go to her friend’s house regularlyC. learn from her classmates at schoolD. share poems and stories with her friend52. In Paragraph 3, “We gave London to each other” probably means ______.A. our exploration of London was a memorable gift to both of usB. we were unwilling to tear ourselves away from LondonC. our unpleasant feeling about London disappearedD. we parted with each other in London53. According to Paragraph 2, the author and her friend _______.A. call each other regularlyB. have similar personalitiesC. enjoy writing to each otherD. dream of meeting each other54. In the darkest moments, the author would prefer to ______.A. seek professional helpB. be left aloneC. stay with her best friendD. break the silence55. What is the best title for the passage?A. Unforgettable ExperiencesB. Remarkable ImaginationC. Lifelong FriendshipD. Noble CompanionsAI built my BBS for the blog competition and disappeared for a long time. Now I just want to take it as my mood board, recording my life in another nation.It’s quite an expected and challenging chance for me to spend one year in the USA. I am a little bit dependent person and easy to miss hometown. Therefore, I need to learn how to be independent and control myself in a sense.The first challenge is cooking. I cannot cook before as we, most young people, are treated well at home and eat in canteens or restaurants, while we have to learn cooking for ourselves since it’s not easy to overcome for me to eat fast food here every day. After the master and two-year PhD studies, I have grasped the skills for doing experiments, so I can cook not that badly via those “talents”. I felt so proud with my masterpieces.The second challenge is going outside. I live in a quite small city without subway, taxi or even public bus (except school catbus). It’s quite inconvenient to live here without a car. However, I have no driving experience in China though I got the license six years ago. I don’t want to spend such a long time to practice it. My friends are very friendly and they drive me to the supermarket and go hiking with me, which makes me a little bit upset or embarrassed as a “bubble” between she and her boyfriend. On the other side, the lack of taking public transportation experience made me so confused when I first went to NYC for a conference. Fortunately, I met several nice guys and they showed me the correct ways. I am looking forward to walking or transporting around on weekends.The third challenge is overcoming loneliness. It’s hard to say why I may feel lonely even though I have Chinese roommates. I still cherish the dream last night that I went back to China even though for experiment purpose...I will work harder to realize my goal and return without any pity.56. Why does the writer use her BBS again?A. To take another competition.B. To disappear for some time.C. To take it as a way to study.D. To keep a record of her foreign life on it.57. How did the writer learn cooking?A. She learned cooking by herself.B. She learned cooking from a cook in a restaurant.C. She learned cooking from books at university.D. She learned cooking from her mother at home.58. What can we learn from paragraph 2?A. The writer bought a car and practiced driving it.B. Going outside on weekends is a terrible thing for the writer.C. The writer’s friends helped her a lot when she went outside.D. The transport is quite convenient where the writer lives.59. What kind of person is the writer?A. Positive.B. Self-centered.C. IndependentD. Weak-mindedBA bullying（欺凌）incident at a primary school in County Armagh, Northern Ireland should not be brushed off as “a joke that went too far”; rather, facts should be dug out and action should be taken to prevent similar events from happening on campus again, according to experts.Dr. Lewis-Snyder, a psychologist specializing in children’s growth issues, said schools should be careful about taking bullying incidents as mere tricks.“Instead, they should work to find out the root cause of the incident in a timely manner, guide the children involved to face and handle the incident in a correct way and teach them to behave properly to avoid-similar situations,” she said.She made the comments after a mother in Armagh posted a description on Face-book on Thursday of how her 11-year-old son was bullied at school, a top school in that area.The mother wrote that her fifth-grade son was the target of bullies who threw a toilet wastepaper basket at him, striking him in the head. The boy was also fooled by his classmates, she said, bringing on acute stress disorder, a mental illness caused by severe anxiety.The mother also wrote that the school described the incident as “a joke that went too far” and that the parents of the boy who threw the basket believed their son was “just being naughty”.The article went viral, with many internet users recalling being bullied at school.Dr. Lewis-Snyder said that schools and parents must pay more attention to the ethical（道德的）development and mental health of children, rather than just looking at their academic performance.The Department for Education, together with a group of other departments, released a series of guidelines last month offering advice on how to deal with the problem.On Saturday, the school involved released a statement on its social media account saying that it had talked to the parents on both sides and would make further efforts to achieve an outcome satisfactory to all parties.60. What can we know from the mother’s description?A. The schools didn’t take the bullying incident seriously.B. The bullying incident caused little harm to her 11-year-old son.C. The parents of the bully felt quite guilty for their son’s behav ior.D. Many other students were also bullied in that school.61. What does Dr. Lewis-Snyder suggest about the bullying incidents?A. Schools should find out the fact and punish the bully seriously.B. Schools should take the responsibility to educate the students to perform properly.C. The government should take action to stop such events happening on campus.D. Parents needn’t care about their children’s academic performance.62. What’s the social reaction to the bullying incident?A. People were indifferent to it.B. It aroused anger on the Internet.C. It caused panic among parents.D. It brought about widespread attention.63. What can be inferred from the passage?A. Most internet users had the experience of being bullied at school.B. The school involved tried to keep the truth from the public .C. The school has taken measures to deal with the incident.D. All the school bullying incidents are caused by classmates conflicts.DA group of Chinese technicians, can be seen working hard among the watermelon fields in the blinding sunlight of Laos（老挝）every January. Two months later, these watermelons will be sent to Xi’an, the starting point of the Silk Road.Every autumn, these so-called “migratory birds（候鸟）” - technicians from Kouzhai village in southwestern China’s Guizhou province - fly to Laos to plant watermelons and return to China next spring to start their own farm work.Yang Canxi, former Kouzhai village Party chief who is also an agricultural technician, said the village was lifted out of poverty through its strength in agricultural technology.He said Kouzhai village was the first to promote small-sized watermelons in the country, and it introduced a new technology to grow watermelons from the newly generated vines after harvesting the old ones, thus doubling the sale to 13,000 yuan, ($2,190) per unit area.In 1997, an official from Laos came to Yang for agricultural training. Twenty professionals were sent to provide watermelon planting skills services there, he said.“At that time, much of the land in Laos was dry and bare except for that used to grow rice. The locals saw technicians plant watermelon and even gave them the nickname of Chinesewatermelon princes”, he said.Each technician earned roughly 10,000 yuan in the first year, which was increased to 20,000 yuan a year later.“Villagers flew into my office, asking to go abroad too,” he said.The business was soon expanded to Laos where Yang Guangyue, 30, and some friends decided to begin their own business in 2013.The local credit cooperative lent them 800,000 yuan to establish a 13-hectare watermelon base in Laos, which was expected to gain roughly two million yuan a year.“Laotians were also hired to work in the watermelon fields and they learned planting skills from us,” he said.Yang Canxi said now half of the income of Kouzhai village comes from this way of working.64. Why do the technicians fly to Laos every year?A. Because they want to enjoy the warm sunlight of Laos.B. Because they need transport watermelons from Laos to Xi’an.C. Because they go to Laos to plant watermelons.D. Because their own land was dry and bare.65. What can be inferred from the passage?A. Both Laos and Kouzhai village benefit from planting watermelons.B. The income of the technicians doubled the next year in Laos.C. The technicians are called watermelon princes because they are handsome.D. It’s hard to expand the business in Laos.66. What’s the best title of the passage?A. “Birds” fly out to work in Laos.B. Changes of Kouzhai village.C. Friendship between Kouzhai village and Laos.D. Watermelon planting in Kouzhai village.AThe earthquake affected the students of the destroyed areas in many ways: losing parents, being scared and feeling lonely. How can we help them? Teens reporter talked with Lin Dan, the program director of the Sunshine in Your Heart Project at the Red Cross Society of China.How will the earthquake affect the teenagers mentally?They'll have feelings of fear, anger and feel they are not safe. They will find it hard to focus. They will tend to cry and shout and tremble. And they might be afraid to be alone.What will happen if they are not helped?The teenagers will find it hard to live in a balanced way. If things get worse, they might not be able to focus on their studies. They might give up on life.How can we help them overcome these problems?The first thing is to build up trust with them. Show your sympathy and sadness, and be their friends. Then you have to give them a sense of safety. Tell them that there's a solution to every problem. Thirdly, try to satisfy their psychological needs. Be a good listener if he or she needs to talk.Some of them were not directly affected by the quake but have seen images on TV and feel scared. What should they do?Talk with an adult or share their feelings with someone who might feel similar. If this doesn't help, then they should see a doctor for professional help.A. The Scare Caused by the EarthquakeB. Dealing with the Pain Left behind after the EarthquakeC. How to Get a Sense of SafetyD. The Psychological Needs68. The underlined word “psychological” in Paragraph 7 is closest in meaning to “________”.A. mentalB. physicalC. materialD. professional69. From the passage, we can infer that ________.A. the scare caused by the earthquake can be relieved quicklyB. seeing a doctor is the most important measure to deal with the problemsC. the images on TV can also affect people and even cause problemsD. to help them overcome these problems, we should always talk with themBSurviving Hurricane Sandy (飓风桑迪)Natalie Doan, 12, has always felt lucky to live in Rockaway, New York. Living just a few blocks from the beach, Natalie can see the ocean and hear the waves from her house. “It's the ocean that makes Rockaway so special,” she says.On October 29, 2012, that ocean turned violent. That night, Hurricane Sandy attacked the East Coast, and Rockaway was hit especially hard. Fortunately, Natalie's family escaped to Brooklyn shortly before the city's bridges closed.When they returned to Rockaway the next day, they found their neighborhood in ruins. Many of Natalie's friends had lost their homes and were living far away. All around her, people were suffering, especially the elderly. Natalie's school was so damaged that she had to temporarily attend a school in Brooklyn.In the following few days, the men and women helping Rockaway recover inspired Natalie. V olunteers came with carloads of donated clothing and toys. Neighbors devoted their spare time to helping others rebuild. Teenagers climbed dozens of flights of stairs to deliver water and food to elderly people trapped in powerless high-rise buildings.“My mom tells me that I can't control what happens to me，”Natalie says, “but I can always choose how I deal with it.”Natalie's choice was to help.She created a website page, matching survivors in need with donors who wanted to help. Natalie posted information about a boy named Patrick, who lost his baseball card collection when his house burned down. Within days, Patrick's collection was replaced.In the coming months, her website page helped lots of kids：Christopher, who received a new basketball; Charlie，who got a new keyboard. Natalie also worked with other organizations to bring much-needed supplies to Rockaway. Her efforts made her a famous person .Last April, she was invited to the White House and honored as a Hurricane Sandy Champion of Change.Today, the scars(创痕) of destruction are still seen in Rockaway，but hope is in the air. The streets are clear，and many homes have been rebuilt. “I can't imagine living anywhere but Rockaway,”Natalie declares.“My neighborhood will be back, even stronger than before.”70. When Natalie returned to Rockaway after the hurricane, she found ________.A. some friends had lost their livesB. her neighborhood was destroyedC. her school had moved to BrooklynD. the elderly were free from suffering71. According to Paragraph 2，who inspired Natalie most?A. The people helping Rockaway rebuild.B. The people trapped in high-rise buildings.C. The volunteers donating money to survivors.D. Local teenagers bringing clothing to elderly people.72. How did Natalie help the survivors?A. She gave her toys to other kids.B. She took care of younger children.C.

先秦儒家已形成比较立体、丰富的生态伦理思想。

这种思想首先体现为乐。

孔子非常擅长在观察自然现象时对自身社会经验进行审视和升华，自然之道和其处世之道在某个合适的时间节点产生共鸣，从而引发孔子深层的思考，其生态情怀也在类似的体悟中逐渐浓厚。

认知自然、体验自然、进而体悟人生哲理，让孔子得出知者乐水，仁者乐山这样的结论。

由乐而生畏。

孔子说：天何言哉？四时行焉，百物生焉。

天何言哉！在孔子看来，四季的轮回、万物的生长都有其运行轨迹和规律，这种力量非人力所能干涉，孔子对自然的敬畏之情也在这种感慨中毕现。

荀子则认为：天行有常，不为尧存，不为桀亡。

既然这种常的力量如此强大，非人力所能改变，聪明的做法就是顺应这种力量并对之合理利用，即荀子所讲的制天命而用之。

那么，该如何制呢？荀子较为强调见微知著、因循借力、顺时守天、因地制宜。

这种总结比起孔子体验式思维多了些理性，已试图对自然与人类社会的道进行理性阐释和总结。

在此基础上，推人及物的思想就产生了。

人皆有不忍人之心是孟子生态道德的基础，不忍心推广于自然万物就成了推人及物的生态道德。

如果说老吾老以及人之老，幼吾幼以及人之幼，……故推恩足以保四海，不推恩无以保妻子是简单适用于人类社会的推恩思维，是简单的换位思考、推己及人，那么，孟子的亲亲而仁民，仁民而爱物则已拓展为推人及物了。

荀子也说：物也者，大共名也……推而别之，别则有别，至于无别然后至。

他认为自然万物有着千丝万缕的，有共性，有同质性；同时，根据某种特质，又可在共性的基础上区分差异，剥离出异质性。

这种异质性基础上的同质性是推人及物的逻辑基石。

在生态实践中，先秦儒者非常强调时禁与适度消费。

胶南一中月考2文科综合历史试题2017．12.211. 钱穆先生在《孔子与论语》中说，儒家论人生，主张节欲寡欲以至于无欲；但绝不许人寡情、绝情乃至于无情。

这表明儒家思想A. 主张建立礼乐制度B. 深受宗法制的影响C. 认同情感的积极性D. 提倡人文理性精神【答案】B【解析】材料中强调了《论语》虽然强调的是节欲寡欲，但不是无情和绝情，这说明儒家思想强调的是人文关怀，注重血缘亲情，所以本题选择B选项。

A选项材料没有体现礼乐制度；C选项只突出了儒家对情的态度，没有体现对欲的态度；D选项材料没有体现出“理性”。

2. 汉宣帝曰：“庶民所以安其困里而亡叹息愁恨之心者，政平讼理也。

与我共此者，其唯良二千石乎！”唐太宗曰：“为朕养民者，唯在都督、刺史……县令尤为亲民，不可不择。

”明太祖称：“府州县官，民之师帅。

”由此可见A. 汉唐明三代出现的地方良吏最多B. 古代统治阶级强化对县官的管控C. 皇帝视地方官为治国的重要帮手D. 封建时代各级地方权力僭越中央【答案】C【解析】从材料中看，无论是汉宣帝、唐太宗还是明太祖都格外强调地方政治的重要性，强调地方官吏是与民众接触最多的人，是联系皇帝与民众的重要的桥梁，所以本题选择C选项。

A选项说法错误，材料没有体现出这一点；B选项错误，材料强调的是地方管理的重要性，不是对官吏的管控；D选项说法错误，过于绝对。

3. 占卜与风水在中国起源很早，但在民间广为流行则始于宋朝，主要原因是A. 商业发达，社会流动加剧B. 社会动乱，瘟疫战争不断C. 理学兴起，儒家思想流行D. 帝王提倡，佛道宗教盛行【答案】A【解析】占卜与风水早在商周时期就已经出现，可是在宋代才广为流传。

分析原因，可以得出商业的发展促进了社会人口的流动，因此占卜和风水使得人民在内心寻求安慰和解脱，所以本题选择A选项。

B选项错误，社会动荡往往无法顾及文化方面的发展；C选项错误，理学思想不推崇占卜和风水；D选项错误，宋代佛道宗教并不是很盛行，且帝王也未有提倡。

（将答案涂在答题纸上相应位置）1. 在水平冰面上，一辆质量为1× 103 kg的电动雪橇做匀速直线运动，关闭发动机后，雪橇滑行一段距离后停下来，其运动的v - t 图象如图所示，那么关于雪橇运动情况以下判断正确的是A. 关闭发动机后，雪橇的加速度为－2 m/s2B. 雪橇停止前30s内通过的位移是150 mC. 雪橇匀速运动过程中发动机的功率为5×103 WD. 雪橇与水平冰面间的动摩擦因数约为0.03【答案】C【解析】A项：关闭发动机后，雪橇的加速度为，故A错误；B项：雪橇停止前30s内通过的位移是，故B错误；C项：雪橇匀速运动过程中发动机的功率为P=Fv=μmgv=5×103 W，故C正确；D项：关闭发动机后，，解得，故D错误。

点晴：速度时间图线与时间轴所围成的面积表示物体的位移，根据图线的斜率求出加速度，匀速运动时，牵引力等于阻力，根据P=Fv求解牵引力功率。

2. 质量为2kg的质点在x-y平面上运动，x方向的速度—时间图象和y方向的位移—时间图象分别如图所示，则质点A. 初速度为4m／sB. 所受合外力为4NC. 做匀变速直线运动D. 初速度的方向与合外力的方向垂直【答案】B【解析】试题分析：x轴方向初速度为v x=4m/s，y轴方向初速度v y=-3m/s，质点的初速度．故A错误．x轴方向的加速度a=2m/s2，质点的合力F合=ma=4N．故B 正确．x轴方向的合力恒定不变，y轴做匀速直线运动，合力为零，则质点的合力恒定不变，做匀变速曲线运动．故C错误．合力沿x轴方向，而初速度方向既不在x轴，也不在y轴方向，质点初速度的方向与合外力方向不垂直．故D错误．故选B考点：运动的合成及分解【名师点睛】本题考查运用运动合成与分解的方法处理实际问题的能力，根据速度图象判断物体在x轴方向做匀加速直线运动，y轴做匀速直线运动，根据平行四边形法则结合牛顿第二定律求解；此题类似平抛运动．中等难度。
