的垂线交AB于点，求证：CE垂直平分BD．【分析】首先根据HL证明Rt△ECB≌Rt△ECD，得出∠ECB＝∠ECD，然后根据等腰三角形底边上的高与顶角的平分线重合即可证．【解答】证明：∵ED⊥AC，∴∠EDC＝∠EBC＝90°，在Rt△ECB和Rt△ECD中，，∴Rt△ECB≌Rt△ECD（HL），∴∠ECB＝∠ECD，又∵BC＝DC，∴CF⊥BD，∴BF＝DF，∴CE垂直平分BD．【点评】本题主要考查了全等三角形的判定和性质，线段垂直平分线的判定定理，正确理解题意是解题的关键．21．（7分）定义：对任意一个两位数a，如果a满足个位数字与十位数字互不相同，且都不为零，那么称这个两位数为“迥异数”．将一个“迥异数”的个位数字与十位数字对调后得到一个新的两位数，把这个新两位数与原两位数的和与11的商记为f（a）．例如：a＝12，对调个位数字与十位数字得到新两位数21，新两位数与原两位数的和为21+12＝33，和与11的商为33÷11＝3，所以f（12）＝3．根据以上定义，回答下列问题：（1）填空：①下列两位数：30，32，33中，“迥异数”为32；②计算：f（34）＝7．（2）如果一个“迥异数”b的十位数字是k，个位数字是2（k+1），且f（b）＝8，请求出“迥异数”b．（3）如果一个“迥异数”c，满足c﹣5f（c）＞30，则c＝71．（请写出满足条件的一个c的值即可．）【分析】（1）①由“迥异数”的定义求解即可；②根据“迥异数”的定义，代入数据并运算，即可求得f（34）的值；（2）根据“迥异数”的定义，代入得出f（b）的值为3k+2＝8，可求得k＝2，再把k＝2代入，计算即可得出b的值；（3）设这个“迥异数”c的个位为n，十位为m，则m≠n，且m，n均为大于1小于10的正整数，可以代入求得f（c）的值为m+n，再根据c﹣5f（c）＞30，可求得关于m和n的不等式，解出后，再对m、n进行讨论就可以求得c的值．【解答】解：（1）①根据“迥异数”的定义，可得：在两位数：30，32，33中，“迥异数”为32；故答案为：32；②∵a＝34，对调个位数字与十位数字得到新两位数43，新两位数与原两位数的和为34+43＝77，和与11的商为77÷11＝7，∴f（34）＝7，故答案为：7；（2）∵一个“迥异数”b的十位数字是k，个位数字是2（k+1），∴b＝10k+2（k+1）＝12k+2，将这个数的个位和十位调换后为：10×2（k+1）+k＝21k+20，∴f（b）＝（12k+2+21k+20）÷11＝3k+2，又∵f（b）＝8，∴3k+2＝8，解得：k＝2，∴这个“迥异数”b＝12k+2＝12×2+2＝26；（3）设这个“迥异数”c的个位为n，十位为m，则m≠n，且m，n均为大于1小于10的正整数．则c＝10m+n，调换个位和十位后为：10n+m，故f（c）＝（10m+n+10n+m）÷11＝m+n，∵c﹣5f（c）＞30，∴10m+n﹣5（m+n）＞30．整理得：5m﹣4n＞30，∴，又∵m≤9，∴，∴，解得：n＜3.75，又∵n为正整数，∴n＝1或2或3，当n＝1时，可得：，m＝7或8或9，此时c＝71或81或91；当n＝2时，可得：，m＝8或9，此时c＝82或92；当n＝3时，可得：，m＝9，此时c＝93；故所有满足条件的c有：71或81或82或91或92或93．故答案为：71（答案不唯一）．【点评】本题考查了对新定义的理解和运用，还考查了列代数式、解一元一次方程和解不等式的知识，最后一问需要讨论不等式的整数解，是本题的难点．22．（8分）已知：等边△ABC，过点B作AC的平行线l．点Q为线段AB上一个动点（不与点A，B重合），将射线QC绕点Q顺时针旋转60°交直线l于点D．如图1，依题意补全图形．（1）求证：∠BDQ＝∠QCB；（2）用等式表示线段BC，BD，BQ之间的数量关系，并证明．【分析】（1）根据题意补全图形即可；根据等边三角形的性质、平行线的性质及旋转的性质得出∠DBE＝∠CQE＝60°，进而可得结论；（2）在BC上取一点P使得BQ＝BP，连接PQ，证明△PBQ是等边三角形，再证明△QBD≌△QPC，即可得出结果．【解答】（1）证明：补全图形如图所示，设QD交BC于点E，∵△ABC是等边三角形，∴∠BAC＝∠ABC＝∠ACB＝60°，∵将射线QC绕点Q顺时针旋转60°，∴∠DQC＝60°，∵l∥AC，∴∠DBE＝∠ACB＝60°，∴∠DBE＝∠CQE＝60°，∵∠BED＝∠QEC，∴∠BDQ＝∠QCB；（2）解：在BC上取一点P使得BQ＝BP，连接PQ，∵∠ABC＝60°，∴△PBQ是等边三角形，∴QB＝PQ，∠BQP＝60°，∴∠BQE＝∠CQP，∵∠BDQ＝∠QCB，∴△QBD≌△QPC，∴BD＝PC，∵BC＝BP+PC，∴BC＝BD+BQ．【点评】本题考查了作图﹣旋转变换，熟练掌握等边三角形的判定和性质及全等三角形的判定与性质是解本题的关键．23．（7分）对于平面直角坐标系xOy中的线段MN及点Q，给出如下定义：若点Q满足QM＝QN，则称点Q为线段MN的“中垂点”；当QM＝QN＝MN时，称点Q为线段MN的“完美中垂点”．（1）如图1，A（4，0），下列各点中，线段OA的中垂点是Q3（2，﹣2）．Q1（1，4），Q2（4，），Q3（2，﹣2）（2）如图2，点A为x轴上一点，若Q（1，）为线段OA的“完美中垂点”，∠QOA ＝60°写出线段OQ的两个“完美中垂点”是（2，0）和（﹣1，）．（3）如图3，若点A为x轴正半轴上一点，点Q为线段OA的“完美中垂点”，点P（0，m）在y轴负半轴上，在线段P A上方画出线段AP的“完美中垂点”M，直接写出MQ ＝﹣m．（用含m的式子表示）．并求出∠MQA．【分析】（1）由“中垂点”定义即可求解；（2）画出图形，根据等边三角形的性质求解即可；（3）分别以A，P为圆心，以AP的长为半径画弧，二者的交点即为M；证明△OAP≌△QAM，根据全等三角形的性质即可得解．【解答】解：（1）∵A（4，0），∴线段OA的垂直平分线为直线x＝2，∵Q是线段OA的中垂点，∴点Q在线段OA的垂直平分线上，即点Q在直线x＝2上，∴点Q的横坐标为2，∴只有Q2（2，﹣2）是线段OA的中垂点，故答案为：Q3（2，﹣2）；（2）∵，∴，∵Q为线段OA的“完美中垂点”，∴OA＝QA＝OQ＝2，即A（2，0）为线段OQ的一个“完美中垂点”，设线段OQ的另外一个“完美中垂点”为L，如下图所示，∴OL＝QL＝OA＝QA＝OQ＝2，∴△LOQ和AOQ都是等边三角形，∴∠LQO＝∠AOQ＝60°，∴LQ∥OA，∴．故答案为：（2，0），（﹣1，）；（3）如图，分别以A、P为圆心，以AP的长为半径画弧，二者的交点在线段P A上方即为M；∵M是AP的“完美中垂点”，点Q为线段OA的“完美中垂点”∴P A＝PM＝AM，OQ＝QA＝OA，∴△OQA和△AMP都为等边三角形，∴∠OAQ＝∠P AM，AQ＝AO，P A＝MA，∴∠OAP＝∠QAM，∴△OAP≌△QAM（SAS），∵P（O，m）．∴MQ＝0P＝﹣m，∠MQA＝∠POA＝90°．【点评】本题考查等边三角形的判定和性质，勾股定理，线段垂直平分线性质，坐标与图形，全等三角形的性质和判定．本题属于新定义的类型题，能结合定义画出对应图形是解题关键．。

AThe Healthy Habits Survey(调查) shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.How many times did you brush your teeth yesterday?Finding: A full 33% of seniors brush their teeth only once a day.Step: Remove the 300 types of bacteria(细菌) in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.How many times did you wash your hands or bathe yesterday?Finding: Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their hands only 4 times a day—half of the number doctors recommend.Step: We touch our faces around 3,000 times a day—often inviting germs(病菌) to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, mostimportant, wash your hands often with hot running water and soap for 20 seconds.How often do you think about fighting germs?Finding: Seniors are not fighting germs as well as they should.Step: Be aware of germs. Do you know it is not your toilet but your kitchen sponge(海绵) that can carry more germs than anything else? To kill these germs, keep your sponge in themicrowave for 10 seconds.1. What is found out about American seniors?A. Most of them have good habits.B. Nearly 30% of them bathe three days a week.C. All of them are fighting germs better than expected.D. About one third of them brush their teeth only once a day.2. How often do doctors advise people to wash hands?A. Twice a day.B. Three times a day.C. Four times a day.D. Eight times a day.3. Where is the text probably from?A. A news report.B. A life magazine.C. A book review.D. An fashion website.BTo develop one’s taste in English, the most effective way is to read English books extensively. Yet one may be at a loss to choose the appropriate books, especially as a beginner. As a native Spanish, I would like to share some of my experience.My first English novel was Jane Austen’s Pride and Prejudice, recommended by many English teachers and professors as an ideal book for English learners. But my experience was somewhat disastrous. I had great difficulty in understanding the novel, let alone enjoying it. It’s not the vocabulary that troubled me, but rather the way the author constructs sentences, and her way of thinking, which seemed too remote to me at that time. My fading enthusiasm was much recovered after reading Hemingway’s novel A Fare w ell to Arms. No long and complicated sentences. And I particularly liked his brief and straightforward(简洁的) style. So my first suggestion is, as a beginner, you’d better choose contemporary novels instead of classical ones. However, if you restrict yourself to novels, you will also miss a lot of treasures. English essays can at once inform you, entertain you, and improve your taste in English. The best example is Bertrand Russell’s work. Its language is plain, yet you cannot help feeling the elegance and the special sense of humor. His simple language enables his philosophy within the reach of ordinary people. So here comes my second suggestion—essays are indispensable.Never follow others’ recommendations and opinions blindly, however famous or influential(有很大影响的) the person might be. We should be open to various ideas, but alwaysthink and determine for ourselves. As a saying goes, one man’s meat is another man’s poison. With that in mind, we are sure to find out our favorite writers through reading and develop our fine taste in English.4. What discourages the author from reading the first English novel?A. Sentence structures and different ideas.B. The old-fashioned words and phrases.C. Many characters and the plain language.D. Brief description and simple sentences.5. What does t he underlined word “indispensable” in Paragraph 2 probably mean?A. Necessary.B. Challenging.C. Avoidable.D. Inspirational.6. What suggestion does the author give in the last paragraph?A. Challenging us to foreign books.B. Reading as many classics as possible.C. Making book choices by ourselves.D. Comparing books before buying.7. What is the author’s purpose of writing the text?A. To give comments on literature works.B. To help beginners choose English books.C. To encourage people to read more books.D. To recommend English classics to learners.CExtreme heat often brings extreme wildfires, and this year is no exception, with heat waves fueling giant outbreaks of fires in the western United States and Canada, as well as across the Mediterranean and in Siberia. However, the wildfires can have the opposite effect on temperatures, cooling Earth's surface regionally and globally.Thick wildfire smoke can temporarily block sunlight near the ground, causing regional temperatures to drop by several degrees. Wildfire smoke can also have global cooling effects by forming smoke clouds or blocking sunlight, which is similar to what a volcanic eruption does.Scientists have recently begun studying these effects since Australia’s 2019-2020 bushfireseason. That was the first time researchers detected wildfire smoke-caused global cooling. The effect is far too small to balance human-caused global warming, but beyond that, researchers say it’s too early to predict what it means for the wider climate system. But with fire seasons growing more serious around the world and this summer witnessing much extreme fire weather in North America and elsewhere, the search for answers is growing increasingly emergent.Scientists at the National Center for Atmospheric Research reported that those Australian fires poured so much smoke into the Southern Hemisphere’s (南半球) atmosphere which caused a “strong and rapid” global cooling effect of about 0.06℃ (0.01°F). According to the lead study author John Fasullo, this was largely due to how smoke particles (颗粒) interact with clouds in the lower atmosphere.While Fasullo’s research highlights the cooling effects of smoke in the lower atmosphere, on occasion, wildfire smoke rushes into the higher atmosphere. There, it can have additional effects on the climate, which is something that is poorly known. “We might still be in the initial stage of understanding how large and how important the effects of these wildfires are,” says Sergey Khaykin, a fire weather expert at Sorbonne University in France.8. What does the second paragraph mainly talk about?A. Wildfire breaks out more often now.B. Wildfire smoke cools Earth's surface.C. Regional temperatures increase due to wildfire.D. V olcanic eruption affects the upper atmosphere.9. What can we learn about wildfire smoke’s effects from Paragraph 3?A. They are too small to be noticed.B. They can be accurately predicted.C. They deserve a deep study.D. They can improve the global climate.10. How does the author prove the global cooling effect in Paragraph 4?A. By giving an example.B. By telling a story.C. By making comparisons.D. By doing an experiment.11. What can we learn from the last paragraph?A. Climate change is in need of a global solution.B. The higher wildfire smoke rushes, the cooler it gets.C. Weather experts are satisfied with Fasullo's research.D. The influence of wildfires needs to be explored further.DRapid advances in artificial intelligence, also called AI, are feared by many in Europe and the US, with scientists warning of wide unemployment. But in Singapore, where foreign workers aren’t allowed to use, leaving many companies struggling for workers, service businesses are increasingly finding automated solutions to their lack of workers.From restaurants to hospitals, robots are being used in a government-backed push to help businesses survive a tight labor market. Louis Tan, chief operating officer of Singapore’s Mount Elizabeth Novena hospital, said: “The government is reducing the number of foreign workers — there is difficulty in hiring even skilled workers. Artificial intelligence has turned out to be one of the solutions.”In a restaurant near the National University of Singapore, dirty dishes are gathered by a robotic waiter that moves between tables chirping: “Could you help me to clear your table?” The machine lacks the ability to pick up cups and plates itself. Instead customers place their used dishes in a tray it carries back to the kitchen. Kannan Thangaraj, the restaurant’s manager, said: “In Singapore it’s very difficult to get workforce from overseas, so it’s very helpful to get a service robot. The customers are coming back because of the robot. They like to see it.”But AI has not been widely welcomed. While there has been a global growth in the use of industrial robots, sales of service sector robots have been left behind. Sales of service robots rose to about 24,000 units in 2014 compared with just under 22,000 the year before. However, analysts predict that the worldwide market for service industry robots is likely to take off, as technical advances allow robots to perform more difficult tasks and work in more complex environments.12. What makes artificial intelligence used in Singapore?A. More profits.B. Lack of labor.C. Customers’ need.D. Wide unemployment.13. What can a service robot do according to Paragraph 3?A. Pick up dirty dishes.B. Place dishes on a table.C. Attract customers back.D. Wash used cups and plates.14. What will the future of service robots be like?A. Uncertain.B. Negative.C. Promising.D. Depressing.15. What’s a suitable title of the text?A. AI labour in SingaporeB. Rapid advances in AIC. AI takes off worldwideD. Singapore revives itself第二节（共5小题；每小题2.5分，满分12.5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。

2022-2023学年广东外语外贸大学实验中学高一下学期期中考试英语试题
2022-2023学年广东外语外贸大学实验中学高一下学期期中考试英语试题1. The turning point of my life was my decision to give up a promising business career and study music. My parents, although sympathetic, and sharing my love of music, disapproved of it as a profession. This was understandable in view of the family background. My grandfather had taught music for nearly forty years. Though much beloved and respected in the community, he earned barely enough to provide for his large family. As a consequence of this example in the family, the very mention of music as a profession carried with it a picture of a risky existence with uncertain financial rewards. My parents insisted on college instead of a music school, and to college I went-quite happily, as I remember, for although I loved my violin and spent most of my spare time practicing, I had many other interests.Before my graduation from college, the family met with severe financial reverses and I felt it my duty to leave college and take a job. Thus was I launched upon a business career—which I always think of as the wasted years. Now I do not for a moment mean to disparage (贬低) business. My whole point is that it was not for me. I went into it for money, and aside from the satisfaction of being able to help the family, money is all I got out of it. It was not enough. I felt that life was passing me by.I continued to make money, and finally, bit by bit, accumulated enough to enable me to go abroad to study music. I resigned from my position and, feeling like a man released from jail, sailed for Europe. I stayed four years, worked harder than I had ever dreamed of working before and enjoyed every minute of it. “Enjoyed” is too mild a word. I walked on air. I really lived. I was a free man and I was doing what I loved to do and what I was meant to do.If I had stayed in business, I might be a comparatively wealthy man today, but I do not believe I would have made a success of living. I would have given up all those inner satisfactions that money can never buy.1.

The Memorial Art Gallery (MAG) opened its doors again this weekend for the University of Rochester’s Clothesline Arts Festival. This event has been an annual tradition at the Centennial Sculpture Park right outside the MAG for the last 62 years. Initially organized with less than 100 artists showing their work on clothes lines and fences, this festival has attracted over 500 artists from across the nation.The park was decorated with colorful tents where artists proudly displayed their works. Each tent was a story within itself — a display of skill, creativity, and years of experience.Piche Design, a unique custom creation art store owned by Chuck Peashy, had one of the most interesting tents: an eye-catching, old setting wi th lamps shaped like musical instruments. “People come to me with objects that belonged to their long-gone loved ones, and I make beautiful items out of those for them. It is, indeed, rewarding,” said Peashy.Jill Schiller started doodling (涂鸦) when she was very young. Her hobby gave way to a series of super cool modern designs. She now draws with Swedish weaving techniques on scarves, carpets, bags, and T-shirts in her tent. Schiller believes that it is evidently a great method of expressing creativity and emotion.George Banagis’ tent, which presented watercolor and pen and ink pieces, had a variety of options. His complicated pen and ink illustrations were available in the original full-size versions, which were made after weeks of effort, and also small, affordable postcards, notepads, and other souvenirs. Visitors loved this inexpensive form of art and flooded inside to buy.Visitors also experienced all seven continents in one tent, Tatarzyn Photography. From penguins lined up on an Antarctic coastline to swans and wandering African elephants, Ted Tatarzyn has traveled all around the world to catch these moments of amazing creatures with a camera. “This isactually my second career,” said Tatarzyn, who interestingly worked at Kodak for many years before its shutdown. He then started touring around the world for the pictures.Strolling across the little artistic showcases is a learning experience that every student should take advantage of. And Clothesline had many other stories to tell.1. What was the Clothesline Arts Festival most probably named after at first?A．The hosting place of the festival. B．The diverse artists joining the event.C．The unique way of displaying works. D．The cloths and various materials used. 2. What do we know about Piche Design?A．It focuses on the musical instrumentB．It helps people recall their loved ones.design.C．It repairs valuable things for people. D．It mainly sells classical furniture.3. What do Jill Schiller’s and George Banagis’ tents have in common?A．They are both about art drawings with strong personal styles.B．They are both popular among university students.C．They both display products with local cultures.D．They are both about inexpensive paintings.4. What is the main topic of the tent Tatarzyn Photography?A．Travel experience sharing. B．Artistic creativity training.C．Professional camera skill teaching. D．Animal photos displaying.5. What is the purpose of the text?A．To remember a 62-year-old tradition. B．To recommend some excellent artists.C．To advertise a secondhand market. D．To introduce a special artistic festival.3. Since the early to mid-2010s, social media apps have made a permanent home in many people’s phones, and spending time on social media has become as much of a daily activity as drinking water. Since so many people are on it for much of their days — especially kids, teens, and young adults —there is increased concern over what social media is doing to people.Many argue that social media is an unhealthy way to pass the time, and that false information from online is causing confusion and panic. This type of thing happens with every generation when something new that people don’t understand comes along: So many people thought rock-and-roll was making teens morally bad, which really wasn’t the case. It is fair to say that the teenage years are hard, and that teens need an escape. Back before phones, teens would listen to rock music as a form of escapism, or they would watch TV, go to the movies, skate around, or dress up in crazy clothes. Unfortunately, all of those things at one point in time were blamed for being a bad influenceon young people. Social media is the new rock-and-roll: it’s a new thing, and people demonize (妖魔化) change.For example, many believe that everything on social media apps is filtered (加滤镜) and that seeing perfect people and their perfectly edited lives often leads to lots of negative emotions. However, models, magazines. and movies have been using retouching (修整) tools for photos and media since Photoshop and other post-production services were invented. Social media has made it easier to see more edited pictures, but social media itself isn’t making people want to look a certain way. Peop le should acknowledge that these pictures aren’t authentic, and the posts are made to look good on purpose. Social media is hot to blame for body confidence issues when the things people want to look like aren’t even real in the first place.It seems like most issues around social media are user errors, like anyone complaining there are too many people being addicted to social media. However, not everyone is addicted to social media; people who have any grasp on reality wouldn’t spend every waking second o n the phone. It is really up to the individual how they use social media. Keeping up with the flood of posts, stories, and photos takes a lot of time — many young people admit that they spend hours on their phones every day. Yet, this seems like an easy problem to solve when the solution is simply clicking off the phone a couple hours early. Therefore, it is clear that moderation (适度) is the key to dealing with all the issues around social media.1. Why does the author mention “rock-and-roll” in Paragraph 2?A．To demonstrate the advantages of social media.B．To predict the future development of social media.C．To explain why social media is regarded as negative.D．To analyze why social media becomes so popular today.2. What does the author think of posting edited photos on social media apps?A．Understandable. B．Disturbing. C．Intolerable. D．Convincing.3. Why do some people spend a lot of time on their phones?A．Because they have grasp on reality.B．Because they want to know what happens.C．Because they can keep up with the modern trend.D．Because they are looking for a solution to the errors.4. What does the text advise people to do about social media?A．Make the best use of it. B．Completely stay away from it.C．Prohibit young people from using it. D．Spend reasonable amounts of time on it.5. Which of the following is a suitable title for the text?A．What makes us so addicted to social media?B．Why is social media so popular among teenagers?C．Should we depend on social media for information?D．Is it right to blame social media for all the problems?4. Wherever we go, we are surrounded by history. Across the globe, cultural heritage (遗产) is passed down through the generations. Yet, we fight a never-ending and very expensive war to preserve it for the future. And today, it is under attack as never before. Technology is often seen as something that destroys the past. 1 .Creating copies via 2D images is extremely laborious and time-consuming. AI technologies are being used to do all the required sourcing, allowing lots of images to be cross-referenced and stored in hours. 2 . AI will also make the restoration and preservation of existing cultural heritage far easier and is vastly superior to previous methods.Airborne technology (机载技术) is being increasingly used in the fight to preserve our cultural heritage. 3LiDAR (Light Detection and Ranging) has already been used to reveal over 60, 000 Mayan structures that were lying undiscovered in the jungles of Guatemala, without needing a single boot on the ground. Drones (无人机) are also being used to document and monitor huge areas and remove the need for all that costly manpower.Human interaction with the most important sites and architecture is doing a great deal of harm. Virtual Reality (VR) technology will play a leading role in preserving our cultural heritage in the coming years. 4 , VR technology will gradually becom e the way that people experience them. We’ll all eventually be able to walk through places, look at (and touch!) artifacts and works of art without ever seeing them with our own eyes.5 . Efforts in research, data sharing and project work will need to be pooled internationally. Using the technical expertise of specialist organizations will become ever more important to the sustainable promoting and preserving of the cultural heritage of countries all across the world.5. A 23-year-old woman has achieved an unbelievable feat that many of us dream of—visiting every country on Earth.Lexie Alford was born into a family of travel agent, which gave her the opportunity to ________ many places during her childhood. She began saving up at age 12 to ________ her goal of visiting all countries. By her 18th birthday, she had travelled to 72 nations. Then one day she suddenly realized she could see the ________ nations on her list in time to set an official record. Many people ________ her travel on social media platforms, so she decided to chase the world record partly to________ others. “Honestly, in the beginning, I ________ wanted to push the ________ of what I thought I could do with my life and see as much of the world as possible in the ________ ,” she told Forbes. “It wasn’t until things started getting really ________ th at I realized I was inspiring people around me, especially the ________”.“The most pleasant surprise about traveling to all these misunderstood areas of the world was that the countries that I had the ________ expectation of ________ being the most incred ible,” Lexie Alford said.“My ________ for young people is to believe that you can do anything you set your mind to do. If you want to travel, you have to ________ sacrifices. And it’s only a matter of ________ until you can make it a reality. ”1.A．remark B．settle C．tour D．love2.A．fund B．quit C．switch D．register3.A．powerful B．ideal C．developed D．remaining4.A．ranked B．modified C．followed D．criticized5.A．inspire B．question C．understand D．accompany6.A．occasionally B．simply C．completely D．temporarily7.A．dream B．button C．family D．observation8.A．platform B．agency C．process D．country9.A．dull B．official C．natural D．challenging10.A．adult B．youth C．boss D．agent11.A．most B．least C．greatest D．worst12.A．started with B．showed off C．ended up D．searched for13.A．advice B．compromise C．belief D．information14.A．save B．appreciate C．worsen D．make15.A．honor B．career C．time D．assessment6. 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。
山东省名校考试联盟2023-2024学年高一上学期11月期中英语试题
山东省名校考试联盟2023-2024学年高一上学期11月期中英语试题学校:___________姓名：___________班级：___________考号：___________一、阅读理解More than 100 podcasts (播客) this year in NPR’s Student Podcast Challenge have touched on a topic that’s increasingly important to young people: climate change. Here are four student podcasts that show the minds of students and what they have to say about climate-related news in their communities — and what they hope to do about it.Behind the Scenes of the Mosquito FireA sixth-grade class at the Georgetown School of Innovation in Georgetown, Calif., shares stories from the devastating (毁灭性的) Mosquito Fire in 2022. This group of eight students asks two firefighters what it’s like to fight fires and protect loved ones in their hometown.Fires: Set AblazeAt Chautauqua Elementary, the Vashon fifth-graders talk about the far-reaching and lasting impact of wildfires and wildfire smoke — and the direct effects on their lives, like waiting for the school bus on a smoky day. The students also interview experts and share their research on wildfire precautions (防范).Flowing Through Time In this podcast from Peak Academy, a group of eight middle schoolers reports on dealing with water shortages in Bozeman, Montana. They track the history of their growing hometown’s water supply, which has been dependent on mountain snowmelt. As that source becomes less reliable in a warming world, the students turn to the grown-ups to ask what they can do to conserve water.Washed AwayThe deadly flooding in eastern Kentucky last year forever changed the lives of high schoolers Ryley Bowman, Carolina Johnson and Hunter Noble. The three classmates at Morgan County High School in West Liberty, Ky., share firsthand accounts of their own and their family’s experiences during the floods.1．Which podcast will be attractive if you are interested in firefighters’ experience?A．Washed Away.B．Fires: set Ablaze.C．Flowing Through Time.D．Behind the Scenes of the Mosquito Fire.2．What do high schoolers share in their podcast?A．Their personal experience.B．The history of water supply.C．An interview with experts.D．Methods of saving water.3．What is the purpose of the text?A．To inspire us to make more podcasts.B．To solve the problem of climate change.C．To introduce students’ podcasts about climate.D．To encourage us to do more for the community.Coco Gauff won the U.S. Open women’s title in 2023. Gauff became only the third American teenager to win the national women’s title four years after she rose to fame in the sport by beating Venus Williams, one of her childhood idols, at the Wimbledon Championships when Gaff was just 15 years old.When Gauff was barely school age she held a tennis racket (球拍) and told her parents that she wanted to be the best player in the world. By the time Gauff was seven, she was training with a tennis professional two hours a day, several days a week. Her father suggested that the family move from Atlanta to Delray Beach, Florida, home to some of the best tennis training camps in the world. At 13, Gauff was the youngest U.S. Open junior girls finalist in history; at 14, she became one of the youngest winners of the French Open junior girls tournament.The win against Venus Williams in the first round of Wimbledon was a bit of a dreamy moment for both players. Gauff was 15; Williams was 39. Gauff beat Williams in straight sets in a stunning upset. When the competitors met at the net for the traditional handshake, Gauff tried to make the moment special. “I was just telling her thank you for everything she’s done for the sport,” Gauff said at the time.Despite her age, Gauff demonstrated skills that both set her apart and made her worthy of being mentioned with other tennis genius, including Tracy Austin, Jennifer Capriati, and Andrea Jaeger. Yet her professional career has not been without its setbacks. Since beating Williams in the first round at Wimbledon, she has found herself knocked out in the first round at the 2022 Australian Open and at Wimbledon in 2023. Still, Gauff has shown consistent improvement in her game on the world stage.4．Why did Gauff’s family move to Delray Beach?A．For comfortable life.B．For stronger competitors.C．For better training.D．For further education.5．How did she make the moment of handshake special?A．By saying thanks.B．By exchanging rackets.C．By overcoming upset.D．By asking for instructions.6．Which of the following words can best describe Gauff?A．Friendly and outgoing.B．Selfless and determined.C．Caring and competitive.D．Hardworking and talented.7．In which section of the magazine can you see the text?A．Friendship.B．Sport.C．Health.D．Culture.In a 2012 study, Boaz Keysar, a professor at the University of Chicago in the US, led an experiment on the relationship between foreign languages and people’s way of thinking.In the experiment, people were asked to make a choice: Just take one pound or take a 50percent chance of winning 2.50 pounds. When given this choice in their native language, most people took the safe option of only getting one pound. But they were more willing to make the riskier choice when asked in a foreign language, leading to more profits overall, according to The Guardian. As Keysar put it, “People just hate the chance of losing, but they hate it less in a foreign language.”In another study published this year, Keysar and his team did an experiment in which participants were given a series of related words like “dream”, “snooze”, “bed” and “rest”. Later, when asked which words they remembered hearing, people were more likely to mistakenly remember “sleep”, which was not on the list, in their native language. But it was much less likely to happen if they did the test in a foreign language. As Keysar explained, people have more careful thinking when using a foreign language, leading to more accurate memories.The foreign language effect may even influence our personality. Silvia Purpuri at the University of Trento, Italy, looked at people’s willingness to face uncertainty and enter unfamiliar situations. Being tolerant (宽容的) of uncertainty allows people to have more creative ideas and be more open to new things. It turns out that people naturally score more highly on this trait (特点) when they can speak or use a foreign language because speaking a foreign language requires taking risks.The evidence is clear: By learning a foreign language, you’re not just learning a language—you’re gaining a new state of mind.8．What does the first experiment suggest?A．People like expressing in a foreign language.B．People are afraid of losing in face of money.C．People make quick choices in their native language.D．People prefer riskier decisions in a foreign language.9．Which of the following best explains “accurate” underlined in paragraph 3?A．Colorful.B．Simple.C．Usual.D．Exact.A．Cool-headed.B．Open-minded.C．Light-hearted.D．Easy-going. 11．What is the main idea of this text?A．Learning foreign languages helps a lot.B．People should learn to face uncertainty.C．Foreign languages influence how people think.D．Personality has an effect on language learning.This year, the social-studies teacher in San Marino, California, plans to let his helper explain some simple topics to his high schoolers. This will free up time for Paccone to focus on more difficult tasks. His new assistant is ChatGPT.ChatGPT is a chatbot, created by OpenAI. Earlier this year, the company’s website became one of the world’s 50 most-visited. When asked a question online, the chatbot will produce an answer that reads like an essay. It is a large language model. This type of model learns to predict what words will come next in a sentence or phrase by looking through vast amounts of text. It places words and phrases into a 3-D map that represents their relationships to each other. Words that tend to appear together, like peanut butter and jelly, end up closer together in this map.ChatGPT marks the beginning of a new wave of AI that will disturb education. Whether that’s a good or bad thing remains to be seen. Some school areas have banned ChatGPT. Teachers are frightened because they see it as a cheating tool. Randi Weingarte, the president of the American Federation of Teachers, says it is to English and to writing what the calculator (计算器) is to math. “But some experts argue that ChatGPT could also be a greathelp. Like calculators for math or Google for facts, an AI chatbot makes something that once took time and effort much simpler and faster. With this tool, anyone can generate well-formed sentences and paragraphs. In the course, writing skills are developed.Now that AI can produce essays, stories and so on, teachers may once again have to rethink how they teach and test. Preventing students from using AI by making students work without access to technology or inviting AI into the writing process? We might have to shift our point of view about what’s cheating and what isn’t.12．Why is Paccone mentioned?A．To give the background.B．To raise a question.C．To introduce the topic.D．To show an opinion.13．What does paragraph 2 mainly tell us about ChatGPT?A．Its wide popularity.B．Its way of working.C．Its style ofwriting.D．Its possible users.14．What is Randi Weingarte’s attitude to ChatGPT?A．Supportive.B．Concerned.C．Confident.D．Uncertain. 15．What is the best title of this text?A．ChatGPT — Friend or Enemy?B．ChatGPT — Necessity or Choice?C．AI — A New Challenge?D．AI — A Great Assistant?二、七选五Kids and teenagers who volunteer aren’t just helping their community. They might alsogroups is connected with better wellness among children and teens.Kids who participated in community service were 34% more likely to be in good physical health than those who didn’t, the study found. And those who volunteered were 66% more likely to be considered doing well in general. Kids aged 12 and older who volunteered were 25% less likely to have anxiety than those who didn’t. The findings come from survey data (数据) provided by the parents of some 50, 000 kids in the United States ages 6 to 17.17Studies like this have limitations. Parents answered questions about their kids’ health and community-service activity. But a parent might not know if their child experiences anxiety orconsiders themselves to be flourishing (健康的). 18 It can only uncover connection. So it’s impossible to say for sure that volunteering leads to better mental and physical health.19 In recent years, rates of depression and anxiety have risen among young people. So there’s a clear need for accessible and effective mental health resources (资源). Giving back to the community may be one such resource.Previous research has also found links between volunteering and well-being among adults. Serving the community seems to help people feel a sense of purpose. 20 Generosity has also been shown to boost happiness and improve physical health. It might be a practice worth cultivating (培养).A．This type of data also can’t prove cause and effect.B．Most of the kids showed great interest in the survey.C．And it makes them feel connected to those around them.D．But the data comes at an important time for youth mental health.E．About half of those parents reported that their kids did volunteer work.F．That’s according to a new research published in JAMA Network Open, in May.G．V olunteering means developing new skills, sharing love, and making new friends.三、完形填空The children in my class quietly worked on their projects. “Nah, nah, nah…” The noisebeen displaying attention-seeking behavior since he joined our class after his family hadpocket.
