B In sculptor Sun Yuli's memory,he remembers his mother as an intelligent and kind woman who had many friends and often made Russian snacks.It turns out that she was an extraordinary woman with stories to tell.His mother,Zhang Yulian,was China's first female war correspondent. 口■ 英语·第4页（共12页） Zhang was bom in the northeastem Chinese city of Harbin in 1914,the year when World War I broke out.Her parents nicknamed her Juju,which translates as"union",in the hope that the small family might weather chaotic times together.Unfortunately,it was not to be.Soon after her mother's death,her father left the 2-year-old with a wealthy,childless Russian couple who raised her from age 2 to 19,when her adoptive mother passed away. In 1937,at the age of 23,Zhang was studying at Yenching University when a Japanese invasion of China broke out.She fled south to escape the bloodshed and later joined former Soviet Union's Tass News Agency (TNA).She came well prepared for the job-fluent in Russian and having done some studies in journalism.She was among many ordinary people who answered the call to defend the country in their own ways. In March 1938,Zhang was sent to cover the Battle of Xuzhou,where she joined other reporters who had to endure daily Japanese bombing as they followed the front line.A Chinese brigadier (she interviewed was surprised to see a female reporter and gifted her a Browning pistol for self-defense.The pistol accompanied her on many fronts across China for the next five years.But in 1942,when Zhang returned to Yenching University to continue with her classes in the southwest city of Chengdu,she had to sell the Browning for travel and tuition.

D.A brief of an event. 英语·第5页（共12页) C Nature is always evolving in fascinating ways,and one lizard from the tropical rainforests of southwestern Costa Rica and Panama is a perfect example of that.Anolis aquaticus,better known as the water anole,is semi-aquatic with a remarkable survival trick.Often called"scuba-diving lizards,"they've developed the ability to create an air bubble over their heads,allowing them to breathe while underwater. These small lizards-with a length of about 6 to 8 inches-are a favorite snack for many predators,including birds and snakes.When threatened,they often dive underwater and form a bubble over their noses using their skin,allowing them to draw in oxygen while submerged. Lindsey Swierk,an assistant research professor of biological sciences at Binghamton University,wanted to learn if this bubble really helped them stay underwater for longer, compared to lizards without a bubble She carried out an experiment where she applied a substance to the lizards'skin to stop them from forming bubbles..“Lizard skin is hydrophobic(疏水的)，”Swierk explains. "Typically,that allows air to stick very tightly to the skin and permits this bubble to form.But when you cover the skin with a cream,air no longer sticks to the skin surface,so the bubbles can't form.” The research revealed that lizards in the control group,which weren't exposed to the cream, were able to remain underwater 32%longer than those without an air bubble."This is really significant because this is the first experiment that truly shows adaptive significance of bubbles," says Swierk."Rebreathing bubbles allow lizards to stay underwater longer.Before,we suspected it-we saw a pattern-but we didn't actually test if it served a functional role." Thanks to their life-saving bubble,water lizards can stay underwater for 20 minutes or longer,allowing them to escape predators and stay safely disguised until the danger passes. Swierk's fascinating findings have led other researchers to look into the creature and what stimulated its survival mechanism.Some guess that the bubble is actually a gill ()and others are wondering if this bubble-breathing adaptation is also common among other lizard species. 28.How do Anolis protect themselves from predators? A.By widening their mouth to pose threatening gestures. B.By blowing bubbles to provide oxygen underwater. C.By changing their colors to hide in the bushes. D.By shaking their tails to make loud noise. 口■口 英语·第6页（共12页） 29.What can we infer from Swierk's words in paragraph 5? A.The experiment is to prove a previous assumption B.The lizard serves a functional role in the ecological chain. C.The study of Anolis has been conducted for a long time. D.The contact of skin and water is important for Anolis. 30.Which of the following will be the possible research direction? A.The classification of this species. B.The practicability of this adaptation. C.The perfection of its hydrophobic skin. D.The contributing factors of its evolution. 31.Which title is suitable for the passage? A.Lizard,the Amphibian Magician B.Evolution:a Fascinating Topic C.Bubble,the Critical Helper D.Survival:a Hidden Drive D In the 1990s,anthropologist Robin Dunbar noticed a link between the size of a primate's (灵长a动物的)brain and the size of its social group.He then suggested that the number of relationships humans can maintain is typically about 150.Now,researchers have applied this idea of Dunbar's number to AI models. Giordano De Marzo,at the University of Konstanz,and his colleagues assigned each copy of the same AI model a random opinion on a binary problem,such as which side of the road a new country should drive on.At each step of the experiment,they chose one copy at random and told it what opinion all the other models held and why,then asked if it would like to update its own-parallel to humans attempting to reach agreement in loose social groups.The results show that high-end AI models could make it every time,yet copies of smaller and less powerful models failed.The results show that although the models in each test were identical,there was no inborn mechanism to reach agreement. Dunbar believes that as models grow more powerful,they will improve the ability to reason about mental and emotional states,which is key to cooperation in humans."It certainly looks promising to achieve scientific breakthroughs because AI could find agreement between different groups much faster than us,"says Dunbar. Philip Feldman at the University of Maryland says AI models with a high Dunbar number may be able to reach agreement on a problem,but that doesn't necessarily mean they will find a good solution.He believes diversity is key to problem solving,which is hard in groups made up 英语·第7页（共12页） of the same AI model."The way that living organisms have solvd this is to have populations different in the way of thinking,"says Feldman. A larger issue is whether it even makes sense to talk about copies of an AI model as a group of individuals,says Michael Rovatsos at the University of Edinburgh."The models don't understand what they are,how they are separate from other models or what the experiment's purpose is.For AI models,presence of others isn't treated any differently from saying'give me a pizza recipe',"he says. 32.What does the underlined word"parallel"in paragraph 2 probably mean? A.Senior. B.Similar. C.Unique. D.Opposite. 33.Which of the following is a binary question? A.What did you want to be when you were a child? B.Who would you choose to be your fitness instructor? C.Have you reviewed the latest version of the document? D.How would you feel about working as part of a team? 34.What's the possible result of lacking diversity? A.The Dunbar number will be restricted. B.Mental and emotional states will get in the way. C.A community will be hard to reach agreement. D.It will be more challenging to tackle difficulties. 35.What problem is implied in the last paragraph? A.AI models have trouble in self-identification. B.AI models lack the ability to generate emotions. C.AI models can't bear the experiment. D.AI models can only respond in one way. 第二节（共5小题；每小题2.5分，满分12.5分） 根据短文内容，从短文后的选项中选出能填人空白处的最佳选项。选项中有两项为 多余选项。 You swing by your favorite convenience store and grab a Coke and snack.That soda is already more expensive than it used to be,and now the payment screen implies you to add a 20%tip on top."Should I pay that extra money?"you may ask yourself. 36.Social media is filled with stories of being asked to tip everywhere from airport stands to fast casual restaurants.So do you really have to shell out that extra dollar or two? Here's what you need to know. 英语·第8页（共12页） Why Americans are tipping more? Myka Meier,a manner expert,tells Money that one cause of that change is wanting to thank workers in higher risk,higher contact service jobs during the COVID-19 pandemic.37. Who should you always tip?When is it OK not to tip? It's easy to feel guilty about skipping that tip when you buy something quick.But Meier says you don't need to.It's not strictly necessary to tip in a fast food or quick service restaurant. 38,she notes,where the expectation is still that customers should leave a tip of between 15%and 20%of their bill. 39,some experts suggest considering whether a worker relies on tips for income.In the case of a cashier,they might not.Waiters and bartenders,on the other hand,often rely on tips as a significant portion of their paychecks.It's also important to consider tips as part of your budget."This is something you should factor into what you're doing,"says Emerald Mills, owner of Turning Tables restaurant. And at the end of the day,it's also important to keep in mind what a tip was originally intended to convey:appreciation for service,even if you're dealing with a fast casual restaurant or stand.40-like taking time to prepare something special for you or being extra friendly during a busy time-you may wish to leave a tip! A.When deciding whether to leave a tip B.That's very different from service at a sit-down restaurant C.Meanwhile,the rise of living cost has been another factor D.It is a part of the culture deeply rooted in the United States E.Tipping used to be about showing appreciation for good service F.If someone goes above and beyond to give you exceptional service G.Confusing,pressure-filled situations like that are increasingly common 第三部分语言运用（共两节，满分30分） 第一节（共15小题；每小题1分，满分15分） 阅读下面短文，从每题所给的A、B、C、D四个选项中，选出可以填入空白处的最 佳选项。 The Royal Ontario Museum (ROM)and I have been friends for more than 80 years,surely some kind of record for romance these days.It plays a(n)41 role in our friendship.The ROM may be shy about expressing 42,yet have always been rewarded with love when I approached it.My passion began when,as a 6-year-old,I skipped up the steps.At the top of the steps,the huge oak doors opened into a large room that combined elements of a castle,made of 43 shades of marble stone,and a shiny ceiling of gold.In the center of the floor 44 an 英语·第9页（共12页） enormous sunburst ()its 45 reaching out to each comner.The cciling was painted with bright symbols,so that looking upward 46 a burst of pure joy.Later in life,it's been my delight to visit the museum.

No fees will be charged.”，说明它提供高质量推荐且有讨论论坛。 B篇 24. 答案B。从文章“Zhang was well prepared for the job -fluent in Russian and having done some studies in journalism.”可知，她有足够的语言和教育背景，所以是TNA理想的战地记者。 25. 答案C。1942年“She had to sell the Browning for travel and tuition.”，表明她需要钱继续学业。 26. 答案A。她在战争期间做战地记者，勇敢面对危险，且为国家而战，体现出勇敢和爱国，A选项正确。 27. 答案C。文章介绍了Zhang Yulian的生平，可能是传记的前言，C选项符合。 C篇 28. 答案B。文中提到“they've developed the ability to create an air bubble over their heads, allowing them to breathe while underwater.”以及“Thanks to their life saving bubble, water lizards can stay underwater for 20 minutes or longer, allowing them to escape predators”，说明它们通过吹泡泡在水下提供氧气躲避捕食者。 29. 答案A。Swierk说“This is really significant because this is the first experiment that truly shows adaptive significance of bubbles... Before, we suspected it we saw a pattern but we didn't actually test if it served a functional role.”，表明实验证明了之前的假设。 30. 答案D。文章最后提到“Swierk's fascinating findings have led other researchers to look into the creature and what stimulated its survival mechanism.”，所以未来研究方向可能是其进化的促成因素。 31. 答案C。文章主要讲水蜥蜴通过头上的气泡在水下生存，气泡对它们至关重要，C选项“Bubble, the Critical Helper”符合文意。 D篇 32. 答案B。“parallel”所在句子“At each step of the experiment, they chose one copy at random and told it what opinion all the other models held and why, then asked if it would like to update its own parallel to humans attempting to reach agreement in loose social groups.”，这里说的是AI模型的行为和人类在社交群体中达成一致的行为相似，所以“parallel”意思是“相似的”。 33. 答案C。“binary problem”是二元问题，只有“Have you reviewed the latest version of the document”是可以用“是”或“否”回答的问题，属于二元问题。 34. 答案D。根据“Philip Feldman at the University of Maryland says AI models with a high Dunbar number may be able to reach agreement on a problem, but that doesn't necessarily mean they will find a good solution. He believes diversity is key to problem solving”可知，缺乏多样性解决难题会更具挑战。 35. 答案A。最后一段提到“The models don't understand what they are, how they are separate from other models or what the experiment's purpose is.”，暗示AI模型存在自我识别困难的问题。 第二节 36. 答案G。上文提到在便利店付款时被提示加小费的困惑情况，G选项“Confusing, pressure filled situations like that are increasingly common”承接上文，说明这种令人困惑、有压力的情况越来越普遍。 37. 答案C。前文说人们给小费的一个原因是感谢高风险、高接触服务工作者，C选项“Meanwhile, the rise of living cost has been another factor”指出生活成本上升是另一个原因，符合逻辑。 38. 答案B。前面说在快餐店或快速服务餐厅给小费不是必须的，B选项“That's very different from service at a sit down restaurant”表明这和坐下来用餐的餐厅服务情况不同，符合语境。 39. 答案A。根据后文“some experts suggest considering whether a worker relies on tips for income”可知，这里是在说决定是否给小费时的考虑因素，A选项正确。 40. 答案F。后文说“you may wish to leave a tip”，F选项“If someone goes above and beyond to give you exceptional service”（如果有人超越常规给你特别的服务），符合给小费的情境。 第三部分 语言运用 第一节 41. 答案C。根据下文作者和博物馆的深厚情谊，这里说博物馆在他们的友谊中起积极作用，“interactive”意为“互动的；积极的”，符合语境。 42. 答案A。博物馆可能不善于表达“喜爱”，但作者每次接近它都能收获爱，“affection”意为“喜爱；感情”。 43. 答案C。大理石有“不同的”色调，“varying”符合文意。 44. 答案B。表示地板中央“躺着”一个巨大的太阳，“lay”有“躺；位于”的意思，过去式为“lay”。 45. 答案D。太阳发出光线，“rays”意为“光线”。 46. 答案A。抬头看天花板“带来”纯粹的喜悦，“brought”是“bring”的过去式，意为“带来”。 47. 答案C。作者去博物馆首先去看恐龙，“stop”在这里有“停留；前往”的意思。 48. 答案B。恐龙是作者在所有展品中最喜欢的，“out of”表示“在……之中”。 49. 答案B。作者被恐龙巨大的“体型”吸引，“sizes”符合语境。 50. 答案D。为死去的恐龙“流泪”，“shed”有“流出；落下”的意思，“shed a tear”是固定搭配。 51. 答案D。恐龙因“陷入”沥青坑而死，“sinking into”意为“陷入”。 52. 答案A。皇家安大略博物馆仍然“占据”着作者的心，“claims”有“占据；索取”的意思。 53. 答案A。80年后作者可能因年纪大了坐轮椅，“wheelchair”符合语境。 54. 答案B。新的展品带来的快乐和作者对博物馆持久的喜爱混合在一起，“enduring”意为“持久的”。 55. 答案C。有些友谊永不“消逝”，“die”在这里意为“消逝；结束”。 第二节 56. 答案enthusiasts。这里指中国chi设计的年轻爱好者，用复数形式。 57. 答案collecting。Huang花五年时间收集图案，这里用现在分词作伴随状语。 58. 答案Over。“Over time”表示“随着时间的推移”。 59. 答案what。这是表语从句，从句中缺少主语，用what引导。 60. 答案practical。修饰名词“application”，用形容词“practical”，意为“实际的；实用的”。 61. 答案to see。“My hope is to do sth.”表示“我的希望是做某事”。 62. 答案by。通过促进商业和文化之间的良性循环，“by”表示方式。 63. 答案notes。主语是he，谓语用第三人称单数形式。 64. 答案globally。修饰形容词“appealing”，用副词“globally”，意为“全球地；在全球范围内”。 65. 答案them。作动词“make”的宾语，用宾格形式。 第四部分 写作 第一节 Dear Mike, I hope you're doing well! I'm glad to share something about the student clubs in my school. There are various clubs, like the English club, art club and sports club. In the English club, we often hold English speech contests and watch English movies. The art club offers a platform for students to show their creativity. And the sports club organizes exciting competitions regularly. I really enjoy being part of these clubs. They not only enrich my school life but also help me make many friends with the same interests. You can imagine how much fun we have together! Yours, Li Hua 第二节 Anyway, I was there, waiting for the signal to start. Looking around, I saw Betsy's determined face and those fit guys stretching their bodies easily. I took a deep breath, trying to calm my nerves. When the signal finally rang, we started running. At first, I managed to keep up with the group, but soon my breath became heavy and my legs felt like lead. I wanted to give up, but seeing Betsy running hard beside me, I forced myself to keep going. One step after another, I struggled forward. Now, sore as my body was, I'm willing to call the race a success. I crossed the finish line, exhausted but proud. I realized that running this race wasn't just about the result. It was about the courage to face my weakness and the perseverance to keep going. And the free beer after the race tasted even better this time. I'm already looking forward to the next race, believing I'll do better. 学科网（北京）股份有限公司 $$
