南宁二中2023-2024学年度上学期高一期中考试物理含答案解析

南宁二中2023-2024学年度上学期高一期中考试物理一、单选题(共35 分)1.小李打算从A地走路到B地,她得到如下两个方案。

若她按方案二出行,则()A.“推荐方案”与“方案二”的平均速度相同B.推荐方案的位移较小C.“方案二”的平均速度约为4.29km/hD.小李运动过程中的加速度不可能一直为0【答案】D【详解】AB.从A地走路到B地,两个方案的初末位置相同,则两个方案的位移相同;根据v=x t由于两个方案所用时间不同,则“推荐方案”与“方案二”的平均速度不同,故AB错误;C.不知道“方案二”的具体位移大小,所以无法求出“方案二”的平均速度大小,故C错误;D.小李运动过程中不可能一直做匀速直线运动,则加速度不可能一直为0,故D正确。

故选D。

2.如图所示,公园里有一仿制我国古代欹器的U形水桶,桶可绕水平轴转动,水管口持续有水流出,过一段时间桶会翻转一次,决定桶能否翻转的主要因素是()A.水桶自身重力的大小B.水管每秒出水量的大小C.水流对桶撞击力的大小D.水桶与水整体的重心高低【答案】D【详解】水管口持续有水流出而过一段时间桶会翻转一次,说明主要原因是装的水到一定量之后,导致水桶与水整体的重心往上移动,竖直向下的重力作用线偏离中心转轴,导致水桶不能稳定平衡,发生翻转,故选D。

3.下列图中各物体均处于静止状态。

图中画出了小球A所受弹力的情况,其中正确的是()A. B. C. D.【答案】C【详解】A.根据受力平衡可知,固定杆对小球A的弹力与重力平衡,方向竖直向上,A错误;B.根据受力平衡可知,小球A受到重力和竖直绳拉力F T1,倾斜绳子拉力F T2应为0,故B错误;C.根据受力平衡可知,小球A受到重力、竖直墙壁对小球A水平向左的弹力F N2、下方小球对小球A沿两球心斜向上的弹力F N1,故C正确;D.根据受力平衡可知,小球A受到重力、沿绳子方向的弹力F N1、半圆轨道对小球指向半圆轨道圆心的弹力F N2,故D错误。

Her fortune is estimated at $100 million, more than many famous actors and musicians earn.So how did it all start?Grumpy Cat's owner Tabatha Bundesen was working as a waitress when her brother Bryan decided to take a photo of her funny-looking cat and post it on Reddit, the social news site. In a matter of hours, she became a sensation(轰动).It got 1 million views on Imgur in 48 hours.Grumpy Cat's real name is Tardar Sauce and she actually has a condition called dwarfism, which makes her constantly frowning. But that unique frown turned out to be worth millions of dollars.Tabatha, who lives in Arizona in US, isn't complaining. She still remembers that September 22, 2012, when her life turned upside down.Since her cat became a worldwide phenomenon, she was able to quit her job and devote her life to managing her cat's modeling career. Sounds unbelievable, but it's true. She says that her only job now is to book Tardar's photo shoots, commercials(商业广告), and other appearances.What are the other benefits of owning a million-dollar cat?Apart from not having to work, Tabatha can travel all the time. She has time and money to visit her family more often and enjoy her life. She never could have imagined just how huge her cat would become, but she always knew Tardar was very special. And she is glad to see her cat bringing joy to so many people around the world.As for the millions of dollars Tardar has earned, they come from all the products, commercials and a best-selling book. She even has her own movie Grumpy Cat's Worst Christmas Ever.24. What does the underlined part “the Internet can't get enough of her”mean?A. The Internet can't stand her any more.B. The Internet pays a lot of attention to her.C. People don't focus on her any longer on the Internet.D. People can’t find enough information about her on the Internet.25. What made Grumpy Cat become famous?A. Her unusual appearance.B. Her bad temper.C. Her short and fat body.D. Her unique fur.26. About Tabatha Bundesen, we know that.A. she now works as a waitressB. she feels very tired of her famous catC. she only manages her cat's modeling careerD. she is too busy to go home to visit her parents27. The general idea of the last paragraph is.A. how the cat can become so famousB. how the cat can make so much moneyC. what the film about the cat is namedD. how the cat's owner spends so much moneyCA new app aims to help parents interpret what their baby wants based on the sound of their cry. The free app ChatterBaby, which was released last month, analyzes the acoustic (声学的) features of a baby's cry, to help parents understand whether their child might be hungry, fussy or in pain. While critics say caregivers should not rely too much on their smartphone, others say it's a helpful tool for new or tired parents.Ariana Anderson, a mother of four, developed the app. She originally designed the technology to help deaf parents better understand why their baby was upset, but soon realized it could be a helpful tool for all new parents.To build a database, Anderson and her team uploaded 2,000 audio samples of infant (婴儿) cries. She used cries recorded during ear piercings and vaccinations to distinguish pain cries. And to create a baseline for the other two categories, a group of moms had to agree on whether the cry was either hungry or fussy.Anderson's team continues to collect data and hopes to make the app more accurate by asking parents to get specific about what certain sounds mean.Pediatrician Eric Ball pointed out that evaluating cries can never be an exact science. "I think that all of the apps and technology that new parents are using now can be helpful but need to be takenseriously" Ball said, "I do worry that some parents will get stuck in big data and turn their parenting into basically a spreadsheet (电子表格) which I think will take away the love and caring that parents are supposed to be providing for the children."But Anderson said the aim of the app is to have parents interpret the results, not to provide a yes or no answer. The Bells, a couple using this app, say it's a win-win. They believe they are not only helping their baby now but potentially others in the future.28. How does the app judge what babies want?A. By collecting data.B. By recording all the sounds.C. By studying the sound of their cries.D. By asking parents about specific messages29. What was the app designed for in the beginning?A. All new parents.B. Deaf parents.C. Ariana Anderson.D. Crying babies.30. What is Ball's opinion about the app?A. Parents should use the app wisely.B. The app can create an accurate result.C. Parents and babies are addicted to the app.D. The app makes babies lose love and caring.31. What is the text mainly about?A. Parents should not rely too much on their smartphones.B. A new app helps parents figure out why their babies are crying.C. Parents can deal with babies' hunger with the help of a new app.D. A new app called ChatterBaby can prevent babies from crying.D"Helicopter (直升机) parenting" describes a style of raising children where parents are overprotective and do too much. The term describes parents who hover over their kids at home and on the playground like a helicopter. Today, modern technology allows these helicopter parents to hover from even far away. They can give their children directions at any moment from anywhere.Julie Lythcott-Haims wrote a book titled How to Raise an Adult: Break Free of the Overparenting Trap and Prepare Your Kids for Success. In her book, she gives readers a closer look at this parenting style. She also explains why parents should stop it.Julie Lythcott-Haims says she experienced the effects of helicopter parenting first-hand when she worked as dean of first-year students at Stanford University. The incoming students, or freshmen, she says, were very smart and accomplished on paper. But many were unable to take care of themselves, "They were turning to parents constantly for guidance, for problem solving, to have them make the choice about something."Lythcott-Haims warns this kind of parenting has many short-term wins but long-term costs that harm the child. She uses an area common to most children — a playground. Lythcott-Haims suggests letting your child get a little hurt."If you do your child's homework, it will be perfect. That is what she calls the short-term win. The long-term cost is that your child may not feel capable (有能力的). And he does not become a determined learner, meaning he will give up easily when faced with a difficult problem to solve." So what can parents do if they want to break the over-parenting "helicopter" cycle? Reading Julie's book, you can follow some ways to stop hovering over your children. In a word, when kids have all the skills to take care of themselves, they will be prepared for adulthood.1. The underlined words "hover over" in Paragraph 1 probably mean _______.A. deal withB. wait forC. stare atD. circle around2. What does the "helicopter parent" believe?A. Short-term wins can harm the kids.B. Getting protection from parents is necessary.C.Trying to make decisions should be valued.D. Learning from failure is helping kids.3. What should parents do for their children based on Julie's study?A. Encourage them to do what they can do.B. Help them grow with parent's protection.C. Guide them in doing as parents do or say.D. Prevent them from playing on a playground.4. What would be the best title for the text?A. Helping Children Is Hurting ThemB. Helping Parents With Their ProblemsC. A Good Way To Teach Your KidsD. Stopping Being "A Helicopter Parent"第二节(共5小题,每小题2分,满分10分)Maybe you are an average student. You probably think you will never be a top student. This is not necessary so, however. Anyone can become a better student if he or she wants to. Here’s how.Plan your time carefully.36 . After making this list, you should make a schedule of your time. First your time for eating, sleeping, dressing, etc. then decide a good, regular time for studying. Don't forget to set aside enough time for entertainment.

广西南宁市第二中学2023-2024学年高一上学期12月测试英语试卷学校:___________姓名:___________班级:___________考号:___________一、阅读理解Asia is the birthplace of the world’s three ancient civilizations: ancient China, ancient India and Babylon. Each gave the world different architectural styles and global landmarks, such as the Great Wall of China. Taj Mahal of India.With the conclusion of the Conference on Dialogue of Asian Civilization, let’s take a look at the architecture of Asian civilizations.The Great Wall of ChinaThe Great Wall of China is an ancient defense project with the longest construction time and the largest workload put into a landmark, stretching out to a total length of more than 5,000 kilometers. Only when you have been to the Great Wall and witnessed its majesty can you truly say you have visited China.Angkor Wat,CambodiaThe Angkor Wat in Cambodia is one of the largest religious monuments in the world,built on a site measuring 162.6 hectares. It was built by the Khmer King Suryavarman Ⅱ in the early 12th century in Yasodharapura(present-day Angkor),the capital of the Khmer Empire, as his state temple and eventual mausoleum(陵墓).Taj Mahal, IndiaThe Taj Mahal is an ivory-white marble mausoleum on the south bank of the river Yamuna in the Indian city of Agra.It was commissioned in 1632 by Mughalemperor Shah to house the tomb of his favorite wife, Mumtaz Mahal. The Taj Mahal was designated a UNESCO World Heritage Site in 1983 for being“the jewel of Muslim art in India and one of the universally admired masterpieces of the world’s heritage”Al-Khazneh, JordanAl-Khazneh, also known as the Treasury, is one of the most delicate temples in the ancient Arab Nabataean Kingdom city of Petra,Jordan. The 45-meter-high and 30-meter-wide building is a magnificent building with a pronounced Greek style. It is said to have been a place where pirates hid their treasure.1.What is special about the Great Wall compared with the others in the article?A.It is the longest man-made project in the world.B.It was listed in the UNESCO world Heritage Site.C.It was used as a defense project in the ancient China.D.It used to be used as a religious/purpose in China2.Which of the following is one of the largest religious monuments?A.The Angkor Wat.B.The Taj Mahal.C.AI-Khazneh.D.The Treasury3.Which of the landmarks has been affected by the Greek culture?A.The Great Wall.B.The Angkor Wat.C.The Taj Mahal.D.AI-Khazneh.Life is like a roller coaster, and every point has ups and downs. People plan something, but luck and sometimes misfortunes lead them toward a different destination. However, passionate individuals are not scared of such uncertainties. They set goals, welcome challenges, overcome obstacles, and eventually achieve what satisfies them.Those who stay committed to their broad goals and find satisfaction even in unplanned circumstances are truly victorious. One true example of such people comes from a woman passionate about spreading happiness and helping others. Nicole Thornes is a mother, a former police officer, and now serving society as a death doula (陪护师).Nicole joined the police academy intending to be helpful to society. She believed that a police officer has the opportunity to eliminate crime, bring justice, and create a better society for everyone. Although she became a mother during her studies and her responsibilities were increased due to children, she didn’t give up on her passion. Nicole could have called off her studies, but her passion for serving society didn’t let her step down. With great efforts, she finally became a police officer and gave her contributions to law enforcement and the betterment of society. She was not only a police officer making full commitment to the society but also a mother who played her responsibilities in the best way possible.Everything went according to her plans, but uncertainty called off her journey as a police officer. Nicole suffered from an injury in a mission that ended her career in the police force. But her dreams and passion did not let her stop. She became a death doula to continue her dream. She chose this field after her grandfather’s death, when she couldn’t bear the pain of losing him. Being a death doula, she is now providing comfort to the dying and their families during difficult times. She aims to spread prosperity in people’s lives and help them overcomeall the obstacles she faced throughout her life.4.What is the first paragraph mainly about?A.Life is full of ups and downs.B.People are at the mercy of changes.C.Uncertainties lead life to a different direction.D.Fulfillment comes from making the best of the uncertainties.5.What is Nicole’s original career commitment?A.To conduct her duty well and better the society.B.To cater to the children’s requirements and needs.C.To accompany the senior through the darkest time.D.To release people’s pain from losing the loved ones.6.Why did Nicole leave her police post?A.Because of the arrangement of the office.B.Because of the injury she got at work.C.Because of the change of interest.D.Because of the danger of the job. 7.What brought Nicole to her new career?A.The appeal of the people in sorrow.B.The push of getting a new job to survive.C.The passion in accompanying the sick ones.D.The sorrowful pain of losing her beloved family.Historians are often asked to examine the actions of our ancestors so we can repeat their wisdom and avoid their mistakes. But the present is just too different from the past. It is a waste of time to study Hannibal’s strategies in the Second Punic War so as to copy them in the Third World War. What worked well in cavalry battles will not necessarily be beneficial in cyber war. Studying history aims to loosen (松开) the hold of the past.A young couple building a new home may ask the architect for a nice lawn (草坪) in the front yard. Why a lawn? “Because lawns are beautiful,” the couple might explain. But why do they think so?The idea of growing a lawn at the entrance to private houses and public buildings was born in the castles of French and English aristocrats in the late Middle Ages. Well-kept lawns demanded land and a lot of work. In exchange, they produced nothing of value. The neat grass at the entrance to castles was a social position symbol nobody could pretend to have. Later the new parliaments (议会), supreme courts, presidential residences increasinglyshowed their power in row upon row of neat green grass. Humans came to identify lawns with political power, social position and economic wealth.When you now come to plan your dream house, you might think twice about having a lawn in the front yard. You are of course still free to do it. But you are also free to shake off the cultural cargo given to you by the upper class. This is the best reason to learn history: not in order to guess the future, but to free yourself of the past and imagine different lives. Of course this is not total freedom — we cannot avoid being shaped by the past. But some freedom is better than none.8.Why does the author mention Hannibal and cavalry battles in paragraph 1?A.To illustrate why future cyber war is difficult.B.To highlight how important historical warfare is.C.To show that past experience may not suit the present.D.To explain what strategies historical figures developed.9.What does the author believe is the real reason for growing a lawn?A.Its connection with power and wealth.B.Its high maintenance requirements.C.Its origin from European castles.D.Its outstanding natural beauty. 10.What do the underlined words “cultural cargo” in the last paragraph refer to?A.Cultural mistakes.B.Cultural standards.C.Historical buildings.D.Historical knowledge. 11.According to the author, studying history is to __________.A.guess events in the future B.repeat wise decisionsC.understand cultural changes D.reduce the control from the pastThe first hibernation (冬眠) studies with human subjects could be workable within a decade, a European Space Agency (ESA) researcher thinks. Such experiments would make it possible for a science-fiction-like approach to long-time space missions that would see astronauts placed into protective sleep for weeks or months on their way to faraway destinations.Experiments have shown that it’s possible to cause hibernation in otherwise non-hibernating animals, such as rats, and bring them safely back to life a few days later. “The rats receive a drug, a neurotransmitter substance (神经递质), and are brought into a dark space with reduced temperature,” Jurgen Bereiter-Hahn, a member of ESA’s hibernationresearch group said. “It works very nicely, but the problem is that you have to apply the drug repeatedly to maintain the state, which could have damaging effects over the longer term.”The hibernating astronaut would not only save the agency cost for water, food and oxygen. Astronauts would, most likely, wake up rather fit, without suffering many of the negative side effects of long-term bed rest or living in microgravity. In fact, studies show that the slowed down cells of a hibernating body don’t get damaged by radiation (辐射). Besides, research in animals suggests that bodies of hibernating astronauts might lose much less bone and muscle mass than the bodies of those awake in microgravity. Upon arrival, these hibernators would thus be fit and ready to start challenging exploration almost straight away after regaining awareness.These protective qualities make hibernation a possibility not just for spaceflight, but also for medicine. Just like astronauts in microgravity, patients in long-term bed rest waste away quickly. Slowing life processes to a minimum would provide what scientists call a “bridge”, a period of time that would allow physicians to look for solutions without racing against the clock. Although most current hibernation research is funded by space agencies, scientists think that the first human to be put into this state of hibernation will most likely be an ICU patient. Once the first human survives and benefits from hibernation, things will likely start moving forward much faster.12.According to paragraph 1, what do the hibernation studies mainly aim to do?A.Improve sleep quality in space.B.Investigate hibernation mystery.C.Promote manned space exploration.D.Enrich science fiction writing methods. 13.What is a challenge in the hibernation experiments?A.Ensuring proper lighting.B.Bringing animals back to life.C.Maintaining low temperature.D.Controlling possible side effects. 14.What advantage might hibernation bring to astronauts?A.It might help to keep physical fitness.B.It might increase long-term bed rest.C.It might decrease radiation contact.D.It might raise mental awareness. 15.What is the last paragraph mainly about?A.The role of physicians in monitoring hibernating patients.B.The possible application of hibernation beyond spaceflight.C.The importance for increasing funds for hibernation research.D.The need of human experiments in advancing hibernation studies.二、七选五Have you ever had this kind of childhood memory: a family sits together casually, drinking and tasting tea after lunch or dinner? 16After being spread to different parts of the world, 17 Now tea has finally received top-level global recognition as a shared cultural treasure of mankind. On Nov. 29, “traditional tea processing techniques and associated social practices in China” was added to the UNESCO list of intangible cultural heritage.Traditional tea processing techniques and associated social practices in China consist of the knowledge, skills and practices concerning the management of tea plantations (茶园) as well as the picking of tea leaves, manual processing, drinking, and sharing of tea, noted UNESCO.18 The most commonly used skills ranging from shaqing (杀青) to xunzhi (窨制). Chinese tea is divided into mainly six categories: green, black, yellow, oolong, white and dark. All of them follow their own processes for tea making. Practices of greeting guests with tea are shared among multiple ethnic groups and provide a sense of identity and continuity. 19 It means boiling tea at a stove — a social tea activity popular among young Chinese people.Weilu zhucha is a replacement in the cold seasons for the camping craze. Sitting around a stove, boiling some tea, people chat, admire the scenery and immerse themselves in traditional Chinese culture by boiling tea together in person. “ 20 Whenever we want some snacks, we sit around a stove and boil tea,” an Internet user commented.A.Take tea making for example.B.This can be fully shown by weilu zhucha.C.tea is common in Chinese people’s daily lives.D.It’s good to feel the warm atmosphere when boiling tea.E.China now has 43 items on the intangible cultural heritage list.F.tea has delighted and fascinated the world for a thousand years.G.This has been a daily activity for Chinese people throughout their history.三、完形填空Chloe Smith is a 6-year-old. girl from Atlanta, Georgia. One day, while taking a walkwas later 23 to discover she had found a stolen Olympic gold medal..The medal belonged to former canoeist (划艇运动员) Joe Jacobi, who won gold while 24 for Team USA in the 1992 Barcelona Olympic games.
