2024届江苏省兴化中学高三高考综合演练(二)英语试题
2024届江苏省兴化中学高三高考综合演练（二）英语试题一、阅读理解King's College Summer School is an annual training program for high school students at all levels who want to improve their English. Courses are given by the teachers of King's College and other colleges in New York. Trips to museums and culture centers are also organized. This year's summer school will be from 25 July to 15 August.More information is as follows：1．Which of the following is TRUE about King's College Summer School?A．Only top students can take part in the program.B．King's College Summer School is run every other year.C．Visits to museums and culture centers are part of the program.D．Only the teachers of King's College give courses.2．How much will you pay the school if you are to attend the program but live with your relatives in New York?A．＄200.B．＄400.C．＄500.D．＄900.3．What information can you get from the text?A．The program will last two months.B．You can write to Thompson only in English.C．As a Chinese student, you can send your application on 14 July, 2022.D．You can get in touch with the school by email or by telephone.In high school I was very shy, content to hang around with my small group of friends and to concentrate on my courses. I was quickly labeled a "brain." I did so well that by the end of senior year I had perfect grades and enough college credits to give up an entire quarter of coursework.But in early June of senior year, the principal called me into his office. He asked me to give a speech at graduation. I was surprised to look at him, my heart thumping. This was the reward for my hard work? I murmured something and fled the office, blaming myself for staying away from physics, a subject sure to have broken up my perfect record.I finally agreed to a compromise. I would share the honor with five other students. I agreed to introduce my friend Judy, who would then give her own, full-length speech.Graduation day soon arrived, I’d been practicing my speech for days, and I had it memorized. The first half hour of the ceremony passed in a blur, and then my moment came. My name was announced. I managed to reach the stage without falling down. I faced my classmates. My voice trembled a little, but mostly it was clear and strong. But within seconds, I was done and heading back to my seat. I accomplished something I’d never dreamed of — I spoke in front of hundreds of people.Although I didn’t realize it at the time, the successful completion of that speech gave me the confidence to take part in class at college, to give oral reports, and to eventually break free of my shyness. I never would have chosen to give a speech at graduation — or ever. But I’m glad I did. Ino longer hesitate when I’m faced with the prospect of doing something I feared. I know it may very well turn out to be one of my shining moments.4．Why was the writer called a "brain"?A．She was the most intelligent student.B．She was the head of her small group.C．She was a bookworm all the time.D．She did more coursework for good grades.5．What can we learn from the second paragraph?A．She ruined her health by studying hard.B．She got the reward as was expected.C．She was grateful for giving a speech.D．She wasn't good at physics at school.6．How did the author feel at the beginning of the graduation speech?A．Excited.B．Moved.C．Scared.D．Embarrassed7．What did the speech bring to the author at last?A．She had nothing to fear in life,B．She won enough college credits.C．She got rid of her sense of shyness.D．She desired to become a speaker.On average, American kids ages 3 to 12 spent 29 hours a week in school, eight hours more than they did in 1981. They also did more household work and participated in more of such organized activities as soccer and ballet. Involvement in sports, in particular, rose almost 50% from 1981 to 1997: boys now spend an average of four hours a week playing sports; girls log hall that time. All in all, however, children’s leisure time dropped from 40% of the day in 1981 to 25%.“Children are affected by the same time crunch that affects their parents,” says Sandra Hofferth, who headed the recent study of children’s timetable. A chief reason, she says, is that more mothers are working outside the home. (Nevertheless, children in both double-income and “male breadwinner” households spent comparable amounts of time interacting with their parents19 hours and 22 hours respectively. In contrast, children spent only 9 hours with their single mothers.)All work and no play could make for some very messed-up kids. “Play is the most powerful way a child explores the world and learns about himself,” says T. Berry Brazelton, professor at Harvard Medical School Unstructured play encourages independent thinking and allows the young to negotiate their relationships with their peers, but kids ages 3 to 12 spent only 12 hours a week engaged in it.The children sampled spent a quarter of their rapidly decreasing “free time” watching television. But that, believe it or not, was one of the findings parents might regard as good news. If they’re spending less time in front of the TV set, however, kids aren’t replacing it with reading. Despite efforts to get kids more interested in books, the children spent just over an hour a week reading. Let’s face it, who’s got the time?8．What does the underlined phrase “the same time crunch” in Paragraph 2 refer to?A．Children have little time to play with their parents.B．Both parents and children suffer from lack of leisure time.C．Children are not taken good care of by their working parents.D．Both parents and children have trouble managing their time.9．In the author’s opinion, a child develops better if .A．he has plenty of time reading and studying B．he is free to interact with his working parentsC．he is left to play with his peers in his own way D．he has more time participating in school activities10．What does the author worry about American kids?A．They are increasingly ignored by their working mothers.B．They are engaged in more and more structured activities.C．They are spending more and more time watching TV.D．They are involved less and less in household work.11．What can we conclude from the text?A．Extracurricular activities promote children’s intelligence.B．Most parents believe reading to be beneficial to children.C．Efforts to get kids interested in reading have been fruitful.D．Most children will turn to reading with TV sets switched off.Move over, helicopter parents. “Snowplow (扫雪机) parents” are the newest reflection of an intensive (强化的) parenting style that can include parents booking their adult children haircuts, texting their college kids to wake them up so they don’t sleep through a test, and even calling their kids’ employers.Helicopter parenting, the practice of wandering anxiously near one’s children, monitoring their every activity, is so 20th century. Some rich mothers and fathers now are more like snowplows: machines moving ahead, clearing any difficulties in their children’s path to success, so they don’t have to suffer failure, frustration (挫折) or lose opportunities.It starts early, when parents get on wait lists for excellent preschools before their babies are born and try to make sure their kids never do anything that may frustrate them. It gets more intense when school starts: running forgotten homework to school or calling a coach to request that their children make the team.Rich parents may have more time and money to devote to making sure their children don’t ever meet with failure, but it’s not only rich parents practicing snowplow parenting. This intensive parenting has become the most welcome way to raise children, regardless of income, education, or race.Yes, it’s a parent’s job to support the children, and to use their adult wisdom to prepare for the future when their children aren’t mature enough to do so. That’s why parents hide certain toys from babies to avoid getting angry or take away a teenager’s car keys until he finishes his college applications.But snowplow parents can take it too far, some experts say. If children have never faced a difficulty, what happens when they get into the real world?“Solving problems, taking risks and overcoming frustration are key life skills,” many child development experts say, “and if parents don’t let their children experience failure, the children don’t acquire them.”12．What do we know about snowplow parenting?A．It appeared before helicopter parenting.B．It costs parents less than helicopter parenting.C．It was a typical phenomenon of the 20th century.D．It provides more than enough services for children.13．What is mainly discussed about snowplow parenting in Paragraph 4?A．Its cost.B．Its benefits.C．Its popularity.D．Its ending. 14．Why does the author mention parents’ taking away car keys?A．To show teenagers are no better than babies.B．To advise teenagers not to treat their cars as toys.C．To advise parents not to buy cars for their teenagers.D．To show it’s appropriate to help children when necessary.15．What’s the possible result of snowplow parenting according to the experts?A．Children lacking problem-solving ability in reality.B．Children mastering more key life skills than parents.C．Children gaining great success in every aspect of life.D．Children meeting no problems or frustration after growing up.Capture spirit of youth“Youth is like the early spring，like the morning sun，like the budding flowers，like the sharp blade fresh off the grinding stone. Youth is the most valuable time of life. "Chen Duxiu，one of the founders of the Communist Party of China，once wrote the Spirit of Youth.16 During this time，habits and interests that will continue for the rest of your life are formed and developed--so it's important to get off to a good start.But what is the spirit of youth It's a time to begin the process of self-reliance and self-motivation. Sure，you might have parents and friends to help you. 17 It builds your character and makes you independent，a necessity to get through the challenges of life. No one can force you to get good grades or get the perfect job-those responsibilities are yours and yours alone. Only you can be the author of your own life.When times get tough，please be persevering. Train yourself to be strong. Tell yourself that you can summon（召唤）the will to overcome whatever obstacles come your way. Anything worth doing isn't easy. 18 In the end，conquering a difficult task is always worth it，and you canthank perseverance for guiding you there.Work hard. There's nothing better than relaxing at the end of a long day，knowing that you did all you could do for yourself，your family and friends，and your community. Be a person that others admire. Do the work that others won't and never complain. The process of working hard will teach you valuable lessons along the way；most importantly，it will teach you that failure is inevitable（不可避免的）but isn't something you should ever allow to hold you back. 19 Following these principles will surely bring success in school，work and life in general. Listen to the spirit of youth inside you and follow your instincts. 20A．Youth is a state of mind.B．Change your strategy and try again.C．It's best to learn that lesson early.D．Be self-reliant，persevere through hard times and always work hard to achieve your dreams. E．Dealing with obstacles is not that easy.F．Youth is a relatively brief period in a man's life.G．But ultimately，you must rely on yourself.二、完形填空Running for a dreamI will never forget that November day．It was hotter than normal．This was the 21 my father and I had waited so long for，22 we had been working towards this race for three years．Dozens of familiar faces from church and school flashed across my view．I saw worry and excitement on my father’s face．Then the race began!For the first two and a half miles，I felt 23 ．I had never before been so ready for something．The weeks leading up to the race were filled with controlled 24 and a strict diet．My friends hadn’t seen me in weeks，but they understood the 25 required to make my dream a reality．As in all of my races，I didn’t start out in the front，I loved the pleasure of 26 people as my strength overtook their premature(提早的)speed．Then without warning，my strength began to 27 ．Neck and neck with one of my greatest competitors，I could see the finish line．I had begun the final dash into 28 when myknees became weak and my legs gave way．Nothing I could do would make them 29 weight．I watched as runners rushed by me．Although I knew my dreams of victory were destroyed I had to finish the race．However，my legs hurt badly．With all of the 30 left in me,I got on my hands and knees and crawled(爬)，inch by inch，across the finish line．V oices，both 31 and familiar，cheered me on．They gave me the courage to keep 32 until the very end．On that point my eyes sought the crowd 33 the only one person I wanted to talked to，my father．I whispered，“I’m so sorry，Dad，I’m so sorry I 34 you．”He looked at me，saying，“You could never let me down．Sometimes these things just happen．All that 35 is that you did your best．”“But we worked so hard．What about our dream?”He reached over for my hand and said．“Don’t you know that you are my dream and it has come true?”What I realized from this，though，was that to him，I was the greatest prize he had ever won．21．A．dream B．weather C．result D．day22．A．so B．why C．because D．since 23．A．proud B．great C．nervous D．afraid 24．A．programs B．studies C．instructions D．practices 25．A．sacrifice B．potential C．patience D．attention 26．A．improving B．passing C．reminding D．replacing 27．A．decrease B．increase C．gathering D．restoring 28．A．relief B．spirit C．pleasure D．glory29．A．give B．feel C．hold D．add30．A．trust B．emotion C．strength D．confidence 31．A．1oud B．foreign C．soft D．firm 32．A．going B．running C．fighting D．training 33．A．into B．for C．from D．of 34．A．frightened B．disturbed C．disappointed D．bored 35．A．differs B．conflicts C．matters D．involves三、语法填空阅读下面短文, 在空白处填入1个适当的单词或括号内单词的正确形式.You may often tell white lies (善意的谎言) to your child. “I've got Santa on the phone and he says he's not coming unless you go to bed now,” is particularly 36 (use) during the festive season, for example.It can seem like nothing: just another tool to improve your child's behaviour.

群文阅读·红色革命小说(二)一、阅读下面的文字，完成1～3题。
(15分 )红岩(节选)罗广斌杨益言在这暗无天日的集中营里，竟有个图书馆，真是想不到的事。
“成岗，你知道么，这里有图书馆!”说完，刘思扬才看见成岗手里也拿着一本书。
原来，成岗是从另一个人手中得到的。
成岗微笑着，没有讲话。
坐在旁边的一个人，这时低声插进来说:“这里的图书馆，书很多。
”牢狱里一片静寂，鸦雀无声，刘思扬缓步走到牢门边，发现，几乎每个牢房，每个人，都在静静地看书。
他立刻醒悟了:这里不仅有复杂的斗争，而且有顽强的学习。
在渣滓洞的时候，他就曾经想过，如果在集中营里能够读书，他一定要好好地把自己武装起来。
失去自由，但不能失去思想，他深深地觉察到战友们专注的学习，正是一种顽强的战斗。
为什么阴森恐怖的白公馆里，会有图书馆呢?刘思扬不解。
但他也初步想到，这一定是战友们多年来斗争的收获。
上午的放风时间终于到了，刘思扬和成岗一先一后地跟着胡浩，用最平静而缓慢的脚步，向图书馆走去。
刘思扬发觉自己的心扑通通地直跳，如同去参加一项冒险活动似的，情绪紧张起来。
图书馆设在一间普通的牢房里。
光线微弱，仅有一个很小的窗户，这房间在楼房的背面，很不引人注目，门是锁着的，管理图书的人还没有来。
“图书管理员是老袁。
”胡浩介绍说，“他马上会来。
”刘思扬记得:老袁是从上饶集中营辗转押来的，但是连他的真实姓名，敌人也还不知道。
在楼上，成岗就给他介绍过，但是不知道他是图书管理员。
一会儿，老袁来了，开了门，先走进去，坐在借书登记的桌边，没有说话。
一踏进房间，成岗和刘思扬都嗅到一股霉臭的味道。
到处是灰尘、蜘蛛网，仿佛他们不是进入一间图书馆，而是进入一座荒废已久的古堡。
满目破旧的书刊废纸，胡乱堆积在摇摇欲坠的书架上。
书架大而且多，塞满了房间，叫人连气都喘不过来。
书架之间，只留着勉强能过人的通道。
通道的地板上，也堆满发黄的陈旧杂志。
借书的人，只能置身在书架的挤压之下，站在废纸丛中，勉强寻找自己需要的书。

专题02 力与直线运动 【讲】-2023年高考物理毕业班二轮热点题型归纳与变式演练(解析版)
专题01力与直线运动【要点提炼】1.解决匀变速直线运动问题的方法技巧(1)常用方法①基本公式法，包括v t 2＝x t ＝v 0＋v2，Δx ＝aT 2。
②v t 图象法。
③比例法：适用于初速度为零的匀加速直线运动和末速度为零的匀减速直线运动。
④逆向思维法：末速度为零的匀减速直线运动可看做反向初速度为零的匀加速直线运动。
(2)追及相遇问题的临界条件：前后两物体速度相同时，两物体间的距离最大或最小。
2．物体的直线运动(1)条件：所受合外力与速度在同一直线上，或所受合外力为零。
(2)常用规律：牛顿运动定律、运动学公式、动能定理或能量守恒定律、动量定理或动量守恒定律。
3．动力学问题常见的五种模型(1)等时圆模型(图中斜面光滑)(2)连接体模型两物体一起加速运动，m 1和m 2的相互作用力为F N ＝m 2·Fm 1＋m 2，有无摩擦都一样，平面、斜面、竖直方向都一样。
(3)临界模型两物体刚好没有相对运动时的临界加速度a ＝g tan α。
(4)弹簧模型①如图所示，两物体要分离时，它们之间的弹力为零，速度相同，加速度相同，分离前整体分析，分离后隔离分析。
②如图所示，弹簧长度变化时隔离分析，弹簧长度不变(或两物体运动状态相同)时整体分析。
(5)下列各情形中，速度最大时加速度为零，速度为零时加速度最大。
4．传送带上物体的运动由静止释放的物体，若能在匀速运动的传送带上同向加速到与传送带共速，则加速过程中物体的位移必与物体和传送带的相对位移大小相等，且等于传送带在这个过程中位移的一半。
在倾斜传送带(倾角为θ)上运动的物体，动摩擦因数与tanθ的关系、物体初速度的方向与传送带速度方向的关系是决定物体运动情况的两个重要因素。
5．水平面上的板块模型问题分析两物体的运动情况需要关注：两个接触面(滑块与滑板之间、滑板与地面之间)的动摩擦因数的大小关系，外力作用在哪个物体上。
若外力作用在下面物体上，随着力的增大，两物体先共同加速，后发生相对滑动，发生相对滑动的条件是下面物体的加速度较大。

White Flower Farm.Eight endangered giraffes trapped on a shrinking island in the middle of a flooding lake are dangerous enough, but the water was crowded with crocodiles. Racing into action were conservationists, government officials, and local community members of Ruko Community Wildlife Conservancy in Kenya to try and construct a “giraffe-raft(救生艇)” in order to ferry them across the lake to safety on higher ground.Longicharo Island in Lake Baringo wasn't always an island, but rather a peninsula(半岛) that split apart after years of intense flooding. The giraffes arrived in 2011, brought by park guarders who believed it was a danger-free place. They kept them fed and healthy, traveling the river by boat. Finally, with more flooding on the horizon, authorities agreed that, with the island continuing to shrink, the threat of losing the valuable animals was too great. One of the tallest and widest of their species, building the giraffe-raft required imagination and planning. It would have to be a strong and balanced one.For several months, the workers familiarized the giraffes with the rescue craft on land until recently when the team calmed Asiwa, an adult female, and covered her eyes to make the trip successfully. Gizmodo had an email exchange with David O'Connor, President of Save Giraffes Now, the non-profit that participated in the daring rescue. He described the special pen(围栏) that was designed specifically for the occasion. "It floats on the top of a series of empty drums and there were specially-built sides that kept Asiwa from jumping out," he explained.Asiwa, has always been a priority for the team on the ground, as she was the most vulnerable. It is a relief for all involved to have got her safely across to the mainland and we are sure she is enjoying the space in her new home! Asiwa is now on dry land and awaits the other giraffes that will join her on a special 4,400-acre reservation with high, secure fencing that should keep them safe from predators.4、Which of the following were stuck in Longicharo Island?A.

Maybe too amazing—the book opens with Alison lying to her mother about having food poisoning so she can take a test on Shakespeare. More than getting good grades, her true motivation is to beat her opponent, Ethan Molloy.Ethan has gone toe-to-toe with Alison on everything throughout school. They're both honors students. They are co-vice presidents of the senior class. They both hope to get into Harvard. The fact that Ethan and Alison seem to always do everything at the same time turned into a competition a long time ago. Whoever does worse on an exam must do an unpleasant task of the winner's choosing. If someone misses the exam, they forfeit.This unfriendly competition is so famous that everyone at Fairview knows about it, students and staff. They're even more annoyed by it than Alison. The principal takes matters in hand by asking the two to co-plan a previous class's ten-year reunion after someone else dropped the ball. As you might imagine, tensions arise and passion is aroused. In a certain way, What's Not to Love is a little like The Hunger Games. Like Katniss with Peeta, Alison is constantly evaluating her own emotions against Ethan's supposed strategy.While reading this book, I was forced to wonder exactly how healthy this relationship was.I assumed everyone's intentions in the book were honorable—the authors themselves turned out all right in the end, and I'm incredibly glad for that. Wibbroka fans will not be disappointed—What's Not to Love is story of soulmates and passion; its short chapters and tight pacing carry the reader along all the way to the satisfying conclusion. Despite its faults—which the text itself calls to attention—fans of enemies-to-lovers stories like How to Lose a Guy in Ten Days will feel right at home here.8、Why does Alison lie to her mother?A. To treat her food poisoning.B. To prove that she's also amazing.C. To be able to be tested on schedule.D. To please her friend with good grades.9、What does "forfeit" in Paragraph 2 probably mean?A. Compete.B. Withdraw.C. Cooperate.D. Succeed.10、How does the principal's attempt to help the two girls end?A. They prove their abilities separately.B. They get the final result of their competition.C. They set up a better relationship between them.D. They use it as another chance to continue the competition.11、What does the author think of the book?A. Worth reading.B. Useless.C. Unreasonable.D. Perfect.The European continent's landmarks shine an even more attractive light than usual—if partly because of their inaccessibility. And few European attractions pop up more often on postcards than its castles.But the best place for serious castle spotters may come as a surprise. It's not France's Loire or Germany's Bavaria. The true centre is Wales, which features more castles per square mile than any other country in Europe.From the northern mountains of Snowdonia to Swansea Bay in the south, castles that could have dropped out of Camelot shoot up everywhere. Why are there so many? Blame it partly on Wales' history as a controversial land. Fighting over it, the Normans, the native Welsh, and the English, led by Edward I, all built splendid castle in an explosion of castle building that occupied the 13th and 14th centuries.The number of Welsh castles is matched by their variety. "For a small country," says historian Kate Roberts, "we have just about every type and form, including concentric castles with moated(护城河) defenses, castles with a strong gate tower, castles that make every possible use of natural defenses, and castles designed to be beautiful luxurious(豪华)houses."That vast range of castles suggests just how deeply the castles reflect Wales' unrest, always shifting history. Take Chepstow Castle, which stands at a cliff overlooking the River Wye. The 11th-century castle started life as one of the first Norman command posts constructed by William FitzOsbern, a close ally(盟友) of William the Conqueror. But it was its next commander, William Marshall, who turned the homely castle into a frightening Norman one, building the first twin-towered gatehouse in Britain.The castle did double duty. It also served as the storehouse for the gold and silver collected by Marshall. Chepstow's most striking attraction is its giant wooden doors - the oldest in Europe—which were originally wrapped in iron plates to both resist invaders and keep Marshall's robbed treasures safe.12、Where are Castle lovers most likely to travel?A. America.B. Wales.C. France's Loire.D. Germany's Bavaria.13、What does Kate Roberts want to say in Paragraph 4?A. Castles can take the place of history.B. People will use the castles as their shelters.C. Castles have been designed as sports.D. There are many castles in Wales.14、Why does the author take Chepstow Castle as an example?A. To show it's designed well.B. To show it has many functions.C. To show it has witnessed unrest changes.D. To show it can be used as a history book.15、Which of the following can be the best title for the text?A. Wales Has the Most Castles in EuropeB. Wales Has the Most Castles in the WorldC. The Castles Are History in the EuropeD. The History of Old Palaces and Castles二、七选五16、 Many quick service restauranteurs are looking ahead to a future where automation will play an important role. They believe it will be the key to greatly increasing their thin profits. ①_____Robots in the workplace can get a bad reputation—most people aren't trying to get replaced by a robot. But the smartest and most creative robotic companies aren't designing teams of robots that send people packing. ②_____ In this way efficiency and profits in the process increase.Take Flippy, the arm-like robotic kitchen assistant. As its name implies, the robot flips(轻翻) burgers, cooking them to perfection. When the orders are ready, it lets its co-workers know, and can clean up after itself by doing dirty and time-consuming jobs like scraping down grills. Introducing Flippy into a kitchen can keep kitchen productivity high and costs low. ③_____ They're designed to be cooperative robots, the cost-effective machines created to work with humans, not against them.④_____ They don't complain about fried food grease getting in their pores(气孔), or burn the chicken tenders after getting distracted by a cute coworker. Quick service restaurants with tools like Flippy are the kind of places you keep coming back to—you know the staff will always have time to answer your detailed questions or joke with your child, and you can also trust your order will always be right on time, perfectly cooked.Automation in restaurants will become even more crucial post-pandemic. Owners then will potentially need workers to enforce updated safety regulations and interact with dissatisfactory guests. ⑤_____ With Flippy having their back in the kitchen, however, they'll know they won't have to worry about burnt burgers on top of confused customers.A. Restaurants are in need of a helping hand.B. It may not be an easy job for those workers.C. Robots are great at efficiency and mindless tasks.D. However, such robots aren't competing for people's jobs.E. Restaurants have an easier time finding workers as places reopen.F. Also, it allows their workers to shine in the tasks no machine can do.G. Instead, they're creating intelligent machines that work alongside workers.三、完形填空（15空）Benjamin Kuo enjoys looking at photos. He especially enjoys 1 precisely where they've been taken.
