河北省承德市丰宁县第一中学2021-2022学年高一物理月考试卷含解析
河北省承德市丰宁县第一中学2021-2022学年高一物理月考试卷含解析一、选择题:本题共5小题,每小题3分,共计15分.每小题只有一个选项符合题意1. 关于惯性,下列说法中正确的是A.同一汽车,速度越快,越难刹车,说明物体速度越大,惯性越大B.物体只有静止或做匀速直线运动时才有惯性C.乒乓球可以快速抽杀,原因之一是因为乒乓球的惯性较小的缘故D.已知月球上的重力加速度是地球上的1/6,故一个物体从地球移到月球惯性减小为1/6参考答案:C2. (单选)如图所示,在水平匀速转动的转盘上,有一个相对转盘静止的物体,它的运动趋势是()高为H,释放A球,让它们自由落下,测得它们落水声相隔时间Δt(s),如果球A距水面的高度H减小,则Δt将A.增大B.不变C.减小D.条件不足,无法判断参考答案:A4. 用绳将重球挂在光滑的墙上,设绳子的拉力为T,墙对球的弹力为N,如图所示,如果将绳的长度加长,则A.T、N均减小 B.T、N均增加C.T增加,N减小 D.T减小,N增加参考答案:A5. 用以下方法可以粗略测定木块和木板间的动摩擦因数:将木块放在木板上,木板放在水平面上,将木板的左端固定,而将其右端缓慢地抬高,会发现木块先相对静止在木板上,后来开始相对与木板向下滑,测得当木块刚好开始沿木板滑动时木板和水平面间的夹角θ.如图,下列说法正确的是()A.木块开始滑动前,其所受的摩擦力先减小后增大B.全过程中木块所受的摩擦力一直在增大C.测得的动摩擦因数为μ=sinθD.测得的动摩擦因数为μ=tanθ参考答案:D解:A、对物体受力分析可知,物体受到重力、支持力和沿斜面向上的摩擦力的作用,在整个过程中,物体受力平衡,所以摩擦力和重力沿斜面向下的分力相等,即f=mgsinθ,所以夹角增大的过程中,木块所受的摩擦力一直在增大,所以A错误.B、当木块在斜面上发生滑动之后,受到的摩擦力为滑动摩擦力,大小为μmgcosθ,可知,夹角越大,受到的滑动摩擦力越小,所以B错误.C、由最大静摩擦力等于滑动摩擦力可知,当夹角为θ时,f=mgsinθ=μmgcosθ,所以动摩擦因数μ=tanθ,所以C错误,D正确.故选:D二、填空题:本题共8小题,每小题2分,共计16分6. 右图表示某物体的v-t图象,从图象可知BC段的加速度是m/s2,物体在这14 s内运动的总路程是_ m,位移是m。

2020-2021学年丰宁满族自治县第一中学高三英语月考试题及答案解析第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AAs the MOOC craze continues to explode, anyone interested in taking an online course faces a tricky question: Which course to take? Here are five aspects that you should consider before you start.(1)What is your learning style?Many MOOCs are video-based. Other courses use presentation formats. Some also require participation in group work. If you want to stay motivated during your course, think about how you enjoy learning.Are you a visual learner, preferring to use images to understand a topic? If so, a video-based course will work well for you. If you are a verbal learner who gains new information by speaking and writing, try a text-based course with lots of note-taking. Social learners, meanwhile, will thrive in forum discussions and project-based assessment.(2)Are you ready to become a full-time student?Be realistic about the time that you can commit to your online studies. Participating in an online course can take as much time and commitment as a class-based program.

It's easy to get caught up in the excitement of taking lots of free courses in everything that you ever wanted to learn. Before you start a course, think about the end goal. Is the course aimed at beginners or advanced learners? Why do you need this qualification?(4) Do you need a support group?Some people learn best from seeing how others approach the problem. If you are such as learner, you will need to supplement your online lessons with an in-person support group.(5) What kind of certification will you get?Take time to find out what kind of certification is available upon completion of the course, and how you can prove your learning to others - for example, certificates, transcripts or digital badges.1. What kind of MOOC's does the author recommend to verbal learners?A. A video-based course.B. A text-based course.C. A forum-based discussion.D. A project-based assessment.2. What kind of learners need an in-person support group?A. Learners who prefer individual work.B. Learners who are in great need of a certificate.C. Learners who are too busy to become a full-time student.D. Learners who learn best from observing how others address the problem.3. What is the passage mainly about?A. Picking the right MOOC's for you.B. Deciding your learning style.C. Taking the right course you need.D. Choosing a suitable support group.BI’ve never been the kind of person to say, “it’s the thought that counts” when it comes to gifts. That was until a couple of weeks ago, when my kids gave me a present thatblew me away.For years now, I’ve been wanting to sell our home, the place where my husband and I raised our kids. But to me, this house is much more than just a building.In the front room, there’s a wall that has hundreds of pencil lines, marking the progress of my children’s growth. Every growth stage is marked in grey, with each child’s name and the date they were measured. Of all the objects and all the memories, it’s this one thing in a home that’s the hardest to leave behind. Friends I know have returned home after work only to discover their wall of heights has been freshly painted over. A new paint job wouldn’t normally be greeted by tears, but erasing that evidence of motherhood hurts more than it should. Our kids grow in so many ways, but the wall is physical evidence of their progress, right there for everyone to see. Over the years, I’ve talked about how much I would hate leaving that wall behind when I moved, even though the last marks were made 10 years ago when my kids stopped growing.So one day, while I was at work, my childrendecided to do something about it.They hired Jacquie Manning, a professional photographer whose work is about capturing (捕捉) the beautiful things in life, from clear lakes and skies to diamonds and ballgowns (舞会礼服).She came to our house while I was at work, and over several hours, took photos of the hundreds of drawings and lines, little grey fingerprints (手印), and old marks. Somehow, she managed to photograph all those years of memories perfectly. Afterwards, she put all the photos together into one image, transforming them into abeautiful history of my family.Three weeks later, my children’s wonderful gift made its way to me—a life-size photo of the pencil lines and fingerprints that represents entire lifetimes of love and growth.4. The underlined phrase in Para. I “blew me away” probably means “________”.A. attracted meB. surprised meC. accepted meD. refused me5. What does the house really mean to the author?A. A house.B. Buildings.C. An object.D. Memories.6. What surprised the friends I know after work?A. Finding the wall repainted.B. Erasing the fingerprints.C. Greeting them by tears.D. Leaving the wall unfinished.7. What is the best title for the text?A. Gift Made with LoveB. Buildings Made by ChildrenC. A Very Wonderful PaintingD. A Family HistoryCThere are three of us in the laboratory: Jules, me and Dr. Leonards. Leonards asks me to sit in front of Jules. As I do, he looks me in the eye and starts to move his face through a series of emotions-happy, confused, surprised, glaring. I'm attracted by his display, feeling delight when hegrinsand feeling serious when his eyes narrow angrily. None of this would be a surprise, of course, if Jules were a human. But he's a robot head on a table.The most special thing is that, consciously(有意识地), there's no mistaking Jules for a real person. Although he has surprisingly realistic skin, his eyes don't fit firmly against his lids, and he has a terrible hairpiece. Yet, as I walk into the room, I experience a complex worry of feeling in his direction. It's not at all like entering an empty space. It's a bit awkward for Jules’ shining false hair. Some unconscious part of me is responding to him as if he's real. This matters, because if we're to one day live comfortably along with robots , an understanding of how we instinctively(本能地) react to them is significant. The study of these issues is the frontier of a new scientificresearch; human-robot interaction.Jules was built as part of an attempt to understand the emotions that can be communicated by a human. “All the robots we'vebuilt so far don't have that rich emotions. We wanted to build a robotic face, with small motors that mimic(模仿) all the muscles you have, so we could discover what it could express. "Such research is becoming increasingly important, says Dr. Leonards, partly because our rapidly ageing population will soon need the help of robots with which they can effortlessly interact.8. What does the author think of Jules?A. He ignored him in his place.B. He didn't treat him as only a robot.C. He was afraid of his being there.D. He mistook him for a real person.9. What is the purpose to build such a robot?A. To help humans of old ages.B. To carry out a scientific research.C. To take the place of human labour.D. To make an interaction with human.10. What doesthe underlined word “grins” mean in Paragraph1?A. Smiles.B. Shakes.C. Worries.D. Cries.11. What may be the best title for the text?A. Human And RobotB. Success Of Making A RobotC. Robot Will Replace ManD. Difference Between Man And RobotDEach year, the women of Olney and Liberal compete in an unusual footrace. Dressed in aprons (围裙) and headscarves, they wait at both towns’starting lines. Each woman holds a frying pan with one pancake inside. At the signal, the women flip (轻抛) pancakes and they’re off!This “pancake racing” tradition is said to have started on Shrove Tuesday, 1445, in Olney. Shrove Tuesday is the day beforethe Christian season of Lent (大斋戒) begins. During Lent, many people decide to give up sugary or fatty foods.Legend says that in 1445, an Olney woman was making pancakes to use up some of her sugar and cooking fats before Lent. She lost track of time and suddenly heard the church bells ring, signaling the beginning of the Shrove Tuesday service. Realizing that she was going to be late for church, she raced out the door still wearing her apron and headscarf and holding her frying pan with a pancake in it. In the following years, the woman’s neighbors imitated her dash to church, and pancake racing was born.The rules are simple. Racers must wear the traditional headscarf and apron. They must flip their pancakes twice - once before starting and once after crossing the finish line. After the race, there are Shrove Tuesday church services. Then Liberal and Olney connect through a video call to compare race times and declare a winner.In both towns, the races have grown into larger festivals. Olney’s festival is an all-day event starting with a big pancake breakfast. Liberal’s festival lasts four days and includes a parade, a talent show, and contests that feature eating and flipping pancakes. Although the women’s race is still the main event, both towns now hold additional races for boys and girls of all ages.12. How did pancake racing start?A. A woman in Olney created it.B. Women made pancakes before Lent.C. A woman dashed to church with a pancake.D. People followed the suit of an interesting incident.13. What should racers obey during the race?A. They can wear fashionable headscarves and aprons.B. They must flip their pancakes once in the race.C. They must flip their pancakes at the beginning of the race.D. They can flip their pancakes in the middle of the race.14. What can we learn about the race from the last paragraph?A. People can show their talent in Olney festival.B. People can enjoy a one-day holiday in Liberal.C. The race is not only intended for women now.D. People can have a big pancake breakfast in both towns.15. What is the text mainly about?A. The origin of pancake racing.B. The history of pancake racing.C. The development of pancake racing.D. The introduction to pancake racing.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

The two main parts are headlined "love" and "partners". They also have an online version of the magazine for serious gossip addicts.Hola: It isSpain's top weekly magazine and the leader of the gossip world. It contains many pictures and a round-up of well-known and less well-known nobles and people in show business. Apart from edited highlights from the present and past issues, there is a report of the week and photo of the week. There is also a French version called OhLa!Revista CUORE: As the third best-selling gossip magazine inSpain, it is mainly aimed at younger teenage readers who look not only for current celebrity gossip, but also for fashion and TV news. It uses a lot of oral terms.Revista SEMANA: It is a Spanish magazine covering the latest news on the famous inSpainandHollywood.

It is also exported to certain parts of theUnited States, bringing together strange and wonderful news from around the world and the famous Latin community.1.Which magazine is also published in French?A.MarujeoB.Revista SEMANA.C.Revista CARAS.D.Hola.2.How many of the magazines mentioned in the text can be read on the Internet?A.Four.B.Three.C.Two.D.One.3.What can be learned from the passage?A.Diez Minutos presents its readers weekly picturesB.Revista CUORE can help improve one's spoken Spanish.C.Revista SEMANA is intended for readers in teensD.Revista CARAS mainly reports news fromLatin America.BAccording to the study posted onScienceDirect, gardening just two to three times a week increase the benefits of better well-being as much as possible and lower stress levels.The research explored why residents engaged with gardening and the extent to which they recognized any health benefits from the activity.A questionnaire was handed out electronically within theUK, with 5,766 gardeners and 249 non-gardeners responding. Data was collected on factors including garden typology(类型学), frequency of gardening and individual awareness of health and well-being."This is the first time the dose response(剂量效应)to gardening has been tested and the evidence from the survey strongly suggests that the more frequently you garden, the greaterthe health benefits," said Royal Horticultural Society (RHS) lead author Dr Lauriane Chalmin-Pui. In fact, gardening every day has the same positive impact on well-being than undertaking regular and powerful exercise like cycling or running.When gardening, our brains are pleasantly entertained by nature around us. Gardening takes our attention away from ourselves and our stresses, therefore, it helps restore our minds and reduce unfavorable feelings.Improving health, however, was not the main motive power to garden, but rather the direct pleasure gardening brought to the participants."Gardening is like effortless exercise because it doesn't feel as exhausting and hard as going to the gym, for example, but we canexpendsimilar amounts of energy," Chalmin-Pui added.Most people say they garden for pleasure and enjoyment, so people who like gardening may be easy to be addicted to it. However, this sometimes may become a piece of good news, from the aspect of mental health. "We hope all the millions of new gardeners will be getting their daily gardening and feeling all the better for it. " Chalmin-Pui said in the interview.4. What can be inferred about gardening from the survey?A. Improving health is the aim of the participants.BGardening makes no difference to health.C. Health benefits from frequent gardening.D. Too much gardening always does harm to health.5. What does the underlined word "expend" mean in paragraph 7?A. Consume.B. Make use of.C. Increase.D. Save.6.

What is Chalmin-Pui's attitude to the new gardeners' gardening?A. Carefree.B. SupportiveC. Tolerant.D. Indifferent.CAlaska—The American city Anchorage is recovering from a powerful earthquake Friday that damaged public buildings, homes and roads.The 7.0 earthquake caused buildings to slake. But there have been no reports of deaths, serious injuries or damage. Officials say the quake has not affected transportation of food and her supplies. “The ships are coming in on schedule, the supply lines are at this point working well,” the government told reporters Sunday.The Glenn Highway was probably the road hit hardest by the earthquake. It connects the state's largest city to other parts in the north. Traffic has been heavy and slow—moving since the quake. Drivers are being guided. Groups of workers are trying to rebuild areas where the quake left large holes in the road.People who are still nervous after the major quake have been more upset by more than 1, 700 aftershocks. “Anything that moves, you feel terrified”said David, whose home suffered structural(结构)damage, including a sunken foundation(地基). Actually, Alaska came up with strict building rules after a 9. 2 earthquake in 1964. That was the second most powerful earthquake on record.Government officials said a public health center promises that moneyfor medical treatment will continue to come. Mental healthy service(心理健康服务)is also available for people hurt by the disaster.Earthquake experts say there is a 4 percent chance of another 7. 0 earthquake or greater in the following week. "The chance is very small, but its not impossible, ” said the expert, Paul Caruso.8. What was the result of the earthquake?A. Buildings were damaged.B. Food supply was cut off.C. Many people were killedD. The ships could not come in.9. Why is the traffic slow on the Glenn Highway?A. Because small quakes hit the city.B. Because falling rocks are a danger.C. Because the highway is badly damaged.D. Because drivers are misled.10. What can you learn from Paul Caruso?A. Another greater earthquake is on the way.B. Chances still exists of another earthquake.C. It will be safe in the 1th week after the quake.D. There is no possibility for more quakes.11. Where can your possibly read the passage?A. Ina story book.B. In a travel journal.C. In a poster.D. In a newspaper.DBrain cells work to actively forget memories during a specific period of sleep. When we sleep our brains clear out the memories we’ve made while we’re awake, deciding what to keep and what to get rid of. Forgetting is an active process, explained the authors of the study published in the journal Science. But less is known about this process during the different periods of sleep.They found that during the rapid eye movement (REM ) sleep period — or active sleep when we are thought to dream — special nerve cells appear to actively contribute to forgetting. What are known as melanin-concentrating hormone-producing (MCH) neurons (神经元) sit in the hypothalamus (下丘脑): a part of the brain which helps with a range of functions such as sleep, appetite and emotions. Past research has suggested these cells help to control REM sleep patterns: activating the MCH neurons increasing time spentin this period, while preventingthemreducing changes into this period.The scientists looked at MCH cells in mice, and found 52.8 percent were active during REM sleep, compared with 35 percent when the mice were awake. Study co-author Thomas Kilduff, director of the Center for Neuroscience at SRI International, told Newsweek the team was surprised to find that mice performed better on learning and memory tasks when the MCH cells were prevented. “This result suggests that activation of the MCH neurons may affect memory — that is, MCH neurons may facilitate forgetting,” Kilduff explained.When asked what motivated the study, Kilduff said, “We hope the work could deepen our understanding of Alzheimer’s disease. Understanding the neural basis of learning and memory is a huge area of neuroscience research because of its effects on our everyday lives, as well as diseases such as Alzheimer’s disease. Prior to this work, no one suspected that MCH neurons had anything to do with forgetting,” said Kilduff.12. What can we infer from paragraph 1?A. Forgetting is a passive process.B. The forgetting process is known to us.C. Some memories are forgotten while we are awake.D. Certain memories are removed while we are asleep.13. What does the underlined word “them” in paragraph 2 refer to?A. REM sleep patterns.B. Past researches.C. MCH neurons.D. A range of functions.14. Why did Kilduff’s team conduct the research?A. To publish the study in the journal Science.B. To know more about Alzheimer’s disease.C. To contribute to human’s forgetting.D. To explore our everyday lives.15. What can we know about MCH?A. MCH cells takes control of REM sleep patterns .B. MCH neurons may disturb memory consolidation.C. MCH neurons have nothing to do with forgetting.D. MCH cells help mice performing better on learning.第二节(共5小题;每小题2分,满分10分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。
