自冬至始绘制“九九消寒图”是古人抵抗寒冬，期待春天的一种风雅活动，下至平民百姓，上至贵族皇室都很热zhōnɡ①。

因梅花位列“岁寒四君子”之首，所以最常见的消寒图就是画素梅一枝，枝上梅花九朵，每朵花瓣九片，每过一天就用颜色染上一瓣，九尽春深，一幅《梅花消寒图》也就画成了。

古人是多么智慧又温情啊！即．使在没有网络，也没有娱乐设施的年代，仍能把万物萧条的寒冷时光过得诗意ànɡ②然。

有了这样闲适从容的心态，寒冬瞬间成了一个美好的过渡，等在后面的是充满希望的暖春。

The mission( 任务) “will change our understanding of the solar system”,wrote Scientific American.In 1998,NASA's Galileo spacecraft found that Europa might be ejecting(喷射)water as far as 160 kilometers into space.That gave scientists the idea of studying the icy moons of Jupiter.The oceans under these moons are likely to be tens of kilometers deep.But they are also trapped under tens of kilometers of ice,making it very difficult to study them.Although JUICE cannot land on the surface,it has lots of high-tech equipment to study the moon's environment,including spectral imaging(光谱成像)tools and radar(雷达) .“They could give more data on things like the thickness of the oceans,their salt content(含量),and their distance from the icy shells above,”reported Phys. org.“The main goal is to understand whether there are habitable(适合居住的) environments among those icy moons and around a giant planet like Jupiter,”JUICE team member Olivier Witasse said during a press conference(发布会)on April 6.9.JUICE has been sent to look for _on Jupiter.A.airB.sandC.goldD.water10.Paragraph 4mainly wants to tell usA.how far water can be ejectedB.why scientists wanted to study JupiterC.what NASA's Galileo spacecraft foundD.which spacecraft was used to explore the universe11.The underlined word"trapped"in Paragraph 5 has the closest meaning to" ”.A.lockedB.createdC.collectedD.taken12.The purpose of the task is to find out if .A.there are living things out thereB.life can live on some of Jupiter's moonsC.there are lakes in the universeD.we can move water from Earth to the moons of JupiterDThe hot pot has a long history of about 2,000 years.The hot pot used to be preferred in winter, but recently it has been appearing on tables all year round.Apart from(除了……外)its delicious taste,there are two other important reasons for the Chinese to like the hot pot.The first one is that the hot pot is considered a great way to make new friends. People gather around the pot,chatting,eating,drinking and having fun.The other is that the hot pot is a healthy meal.Eating the hot pot can warm the body and improve circulation(血液循环)in winter, and increase perspiration(出汗)to help cool the body in summer.There are several kinds of hot pots in China with different soup.Two of the most popular hot pots are Sichuan hot pot and Beijing mutton hot pot.Sichuan hot pot is famous for its numbing and spicy(又麻又辣的)taste,due to the addition of a special food material—Sichuan pepper—and other spicy things like chilli,which makes it different from other hot pots.Beijing mutton hot pot is regarded as the typical northern China hot pot.Mutton is its main part,and the soup is made from lamb bones.When you eat a hot pot in a restaurant,generally,there are two kinds of soup bases:spicy and clear.A clear soup base has quite a mild(温和的)taste,which is made from seafood or meat bones.A spicy soup base usually has Sichuan pepper,which is spicy and salty.If you have a mixed group with some who don't eat spicy food,there is a special pot with a divider in the middle between the spicy and clear soup,which is called a double-flavor hot pot(鸳鸯锅).13.The hot pot is popular because①it tastes delicious②it is cheap and easy to make③it is a way to make friends④it is a healthy mealA. ①②③B. ②③④C.①③④D.①②④14.Paragraph 4mainly talks aboutA.the typical northern China hot potsB.the introduction of two hot potsC.the taste of Sichuan hot potD.the food material of Sichuan hot pot15.In Paragraph 6, the writer advises the mixed group toA.give up eating any hot potB.choose a clear soup baseC.enjoy Beijing mutton hot potD.try a double-flavor hot pot16.Match the different kinds of the hot pots with the characters(特点)according tothe passage,①Sichuan hot pot ②Beijing mutton hot pot ③double-flavor hot pota.a typical northern China hot potb.the numbing and spicy tastec.the clear soup and the spicy soup are both includedA.①—b;②—a;③—cB.①—a;②—b;③—cC.①—c;②—a;③—bD.①—b;②—c;③—a第二节阅读短文，从方框内所给的选项中选出可以填入空白处的最佳选项，其中有一个多余的选项。

材料一：有一些学者对ChatGPT在教育中的使用表示担忧。

总的来说，虽然ChatGPT在教育中的应用存在很大潜力，但也存在学业诚信遭质疑、师生过度依赖、信息传输不准确等风险与挑战。

ChatGPT能在多门学科中帮助学生完成学习任务，提高教学成果的完成度与创意感，但也引发了学者们对学生学业诚信的担忧。

有研究者提出，ChatGPT可能会帮助学生实施作弊，使教育评估机制失去平衡，导致教育不公平的问题。

有研究者通过测试ChatGPT与真实考生在大学开放性考试中的作答结果后表示，ChatGPT的推出可能导致在线考试和开放性考试学术诚信的终结，因为ChatGPT的考试答案展现出了高度的批判思维和逻辑思维，能在很少的输入下生成高度逼真的文本，使学生在考试中作弊成为可能。

此外，教务人员也表示很难区分学生和ChatGPT生成的写作内容，并且当学生使用ChatGPT回答问题时，教务人员很难充分评估学生的真实理解水平。

诚然，ChatGPT和其他内容生成类模型能为学生提供互动学习，让学生在互动中受益。

2014年的一项研究也证明，与模仿人类情感行为的虚拟导师互动的学生学习效果更好。

但是，学生在多次使用ChatGPT后，很可能会产生一定的依赖心理。

尤其在多次使用其协助完成学习任务并获得较好的成绩后，学生很可能沉迷于其效果。

因智能工具产生依赖进而养成惰性心理是有先例的。

如早前多有报道学生依赖作业搜题工具而导致学习成绩下降的问题。

For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, used one word that best fits each blank.An implant that can cool nerves to block pain signals has been unveiled by researchers who say the device could offer an alternative to drugssuch as opioids (类鸦片活性肽).The team behind the device say it could bring benefits for management of acute pain such as (21)_______ experienced after amputations (截肢)or nerve grafts."We are optimistic that this represents a very promising starting point for an engineering approach (22)_______ treating pain,” said Prof John Rogers of Northwestern University in the US, a co-author of the research. But he cautioned that it might be some time (23) _______ they were available to patients. "As with any implantable device, the regulatory process can be slow, typically (24) _______ (involve) much more extensive animal model studies over a period of years," he said.Writing in the journal Science, the team report that the device to block pain signals, which (25) _______(test) only on rats so far, involves a pump, external control system and an implant made from a soft, rubbery substance. The latter forms a sealed collection of tiny channels which form a twisting path in the part of the implant that sits around the target nerve like a cuff.When liquid coolant and dry nitrogen flow through the implant, the liquid causes a drop in temperature. An electronic sensor in the device allows the temperature at the nerve (26) _______(keep) constant."All body processes are based on metabolic chemical reactions, motions of ions and flows of fluids--all (27) _______slow down as a result ofcooling,” said Rogers. “ The net effect when cooling is applied to a nerve is in blocking of electrical signals."Among their experiments, the team tracked two rats with an injury, recording over a three- week period the minimum force that (28)_______be applied to the hind paw to cause the animal to retract (缩回)it. This data was then compared against three rats who were similarly injured but also had the implant. The results suggest bouts of cooling of the injured nerve from 37℃ to 10℃led to (29) _______(severe) pain, with a sevenfold increase in the force that could be applied to the paw. The team say the implant’s benefits include (30)_______, in contrast to opioids, it is not addictive. As the implant is made with water-soluble and biocompatible materials, it can break down in the body after use. The implant could be inserted as an extension of the patient’s initial surgery.Section BDirections: Complete the following passage by using the -words in the box. Each word can only be used once. Note that there is one more word than you need.A. attachedB. bottle-fedC. confusionD. invisibleE. originallyF. orphanedG. partneringH. procedureI. reproducedJ. subjectsK. unintentionallySaving Baby BearsReacting to the auditory assault of barking dogs, shouts and rifle blasts, a 168-pound American black bear shot out and hightailed (迅速逃走)it into the woods off a logging road.His sister, weighing in at 135 pounds, took a little more time to overcome her fear and (31) _______ before she, too, ran for the trees and away from the humans who had driven more than 100 miles to witness the bears’ return to the wild.The cubs were the 106th and 107th (32) _______ or injured bears to be raised or treated at the Progressive Animal Welfare Society (PAWS) Wildlife Center in Washington state, then released months later in the same general area where they were (33) _______found. Fitted with GPS collars and tattooed with identification numbers on their gums, the bears are also among the latest (34) _______of a long-term research study being conducted by Rich Beausoleil and Lindsay Welfelt, both biologists and bear and cougar specialists.The siblings were only two weeks old when a forest worker and his dog (35) _______ disturbed their den in February 2020, scaring away their mother. She never returned.The worker contacted the WDFW, an agency (36) _______with PAWS to rehabilitate sick, injured wild animals before releasing them back into their natural habitats."Their eyes and ears weren't open, and their teeth hadn't evenerupted,Jennifer Convy, PAWS senior director of wildlife, said of the cubs, which each weighed less than 2 pounds when they arrived and were the youngest ever to be raised at the center.Though (37) _______at first, the cubs weren't cuddled. Instead, their caregivers wore bear- scented bear suits during feedings once the cubs' eyes had opened. At PAWS, the staff and volunteers take pains to be (38)_______to all the animals in their care."They don't see us, ever. We don't talk to them. We don't name the animals because we don't want our staff or volunteers to get (39)_______，“ Convy said. After more than a year, the bear siblings were released.The wildlife biologists are studying how the bears raised at PAWS fare after their release, compared to their wild-reared brethren. One cub released in 2017 had her first litter of cubs in January."We've been to her den several times." Beausoleil said. "She (40)_______ and had cubs of her own ... This was kind of a turning point for us."After all, the whole point of PAWS' rehabilitation "is to protect and perpetuate (使持续) the species," he said.III.

A note written in a manuscript in the library (42) _______the account of da Vinci's first biographer, Giorgio Vasari: that the sitter was a merchanfs wife, Lisa Gherardini. The note also helped date the masterpiece to between 1503 and 1506.A(n) (43)_______ mystery-"Where "- is still in dispute. But on June 3rd a French engineer, Pascal Cotte, declared that he and a collaborator had (44) _______the landscape in the background of the painting. Arguments had (45)_______ been made for stretches of countryside in the Marche region and between Milan and Genoa. During a presentation in Vinci, near Florence, Mr Cotte maintained that the artist was more plausibly depicting a part of his native Tuscany 一one that keenly interested him at the time. According to this theory, da Vinci represented the area not as it was, but as, in an unrealised scheme, he (46) _______ it to be.Mr Cotte, who was asked by the Louvre (where the "Mona Lisa" hangs) to create a digital image of the painting, is the inventor of themultispectral camera: a device that can detect not only the drawing below the (47) _______of an oil painting, but also, where they exist, intermediate layers of work. It was among these, under what appears to be a pointed rock, that he found a(n) (48) _______sketch showing that da Vinci meant it to represent a castellated tower.The landscape of the "Mona Lisa" also includes a huge overhanging cliff. That is (49)_______ to one that da Vinci included in a sketch of a fortress (堡垒)contested by Pisa and Florence in the war that flared between them in 1503 (around the time he was painting Gherardini). The (50)_______ with the nearby cliff ——and a tower, known as the Caprona tower 一all overlook the river Amo as it snakes from Florence to Pisa. All three also feature in drawings made by da Vinci to illustrate a plan about which, says Mr Cotte, he became “(51) _______”.This involved diverting the Amo to (52) _______Pisa's water supply and give Florence an outlet to the Mediterranean. In the early 1500s, with the two citystates at war, the idea was under active consideration. Mr Cotte argues that a(n) (53) _______ winding through desolate countryside at the right of the "Mona Lisa" is too wide to be a road, as some have speculated, and is(54) _______the driedup bed of the Amo as da Vinci envisaged (设想)it once his plan had been adopted.It never was. But if Mr Cotte's theory is right, it might just explain why Gherardini, a Florentine, exhibits such a contented, if mysterious, (55)_______。

一、现代文阅读（35分）（一）现代文阅读I（本题共5小题，17分）阅读下面的文字，完成1～5题。

材料一：中央广播电视总台《典籍里的中国·越绝书》篇的播出，让地方志书中沉淀着历史烟云、凝结着先贤智慧的文字和思想，引领着更多人去感悟蕴含其中的家国情怀，去思考和探寻“何以中国”的更多答案。

要探寻答案，就必须读懂中国地方志里的故事，读懂故事里那些永载史册的人物，那些可歌可泣的历史瞬间，还有那些闪耀在字里行间、激荡在心灵深处的人性光辉。

英国学者李约瑟曾指出：“希腊的古代文化乃至近代英国，都没有留下与中国地方志相似的文献。

要了解中国文化，就必须了解中国的地方志。

”地方志为人们读懂中国故事打开了“一扇窗”。

上溯夏禹，下迄两汉，旁及诸侯列国，一部看似平常无奇的《越绝书》，以越地为视角，将华夏千百年历史激荡浓缩其中。

从书里，我们可以读到那些流传千古的故事：“卧薪尝胆”“三千越甲可吞吴”“子贡一出乱五国”····子贡游说五国、改写五国形势的绝世智谋，勾践转死为生的家国情怀，千年之后，仍然让我们心驰神往、热血沸腾。

通过阅读方志里的中国故事，我们可以“穿越时空”，从中汲取到向上向善的精神力量。

除了读懂中国故事，还要关注地方志里的中国精神。

党的二十大报告中提出：推进文化自信自强，铸就社会主义文化新辉煌。

中国精神是中华文化的精粹，是中华民族刻入筋骨的精神特质，是中国人民昂扬奋进的精神风貌，是团结一心的精神纽带和自强不息的精神动力。

D．A history story.CAlpha, Beta, Delta... these Greek letters used to only appear in our math classes but are now in use in news headlines.Now, it’s Lambda. As the Delta variant (变体) spreads throughout communities in Asia, Europe and the United States, another variant, Lambda, is spreading rapidly throughout South America, Forbes reported on Aug 10.On May 31, the World Health Organization (WHO) announced a naming system for variants of COVID-19 that uses letters of the Greek alphabet (字母表). Before that, the public had to call a variant its scientific name or refer to it based on where it was identified.For example, a variant of COVID-19 identified in South Africa in late 2020 was calledvariant 501Y.V2 or B．1.351. Media also called the same virus “the South African variant”. Now, everyon e calls it “Beta”.Compared to complicated scientific names, the Greek letters are much easier to remember. “It is a lot easier for a radio newsreader to say ‘Delta’ than bee-one-six-one-seven-two,” Jeffrey Barrett, a UK statistical geneticist told Nature.WHO hopes this change will help stop the stigma (污名) associated with geography-based names. “I can understand why people just call it ‘the South African variant’ —they don’t mean anything by it,” Salim Abdool Karim, an epidemiologist in South Africa, tol d Nature. “The problem is, if we allow it to continue, some ill-intentioned people may take advantage of it.” “No country should be stigmatized for detecting and reporting variants,” Maria Van Kerkhove, WHO’s COVID-19 technical lead, wrote on Twitter.As the virus is still evolving, 11 variants have been named so far. What if the 24 Greek letters are not enough? “We will possibly run out of the Greek alphabet, but we’re already looking at the next series of names,” Van Kerkhove told The Telegraph. “We’re ac tually considering star constellations(星座).”Currently, the Virus Evolution Working Group and WHO’s legal team are double checking proposals to “make sure we don’t upset anyone with these names”, Van Kerkhove told The Telegraph.11．What do Lambda and Delta have in common?A．They are both chosen by Greek scientists.B．They are both confusing to understand.C．They are both Greek names of varieties of COVID-19.D．They are both the places where COVID-19 was found.12．What does Salim Abdool Karim probably agree with?A．The virus should be named after the place where it is found and spread.B．No country should detect or study COVID-19 without WHO’s permission.C．People felt uncomfortable when they call COVID-19 “the South African variant”.D．Some people with bad intention may judge other countries reporting COVID-19.13．Why are scientists looking for the next series of names?A．Because the naming system in use is not convenient.B．Because the variants may outnumber the Greek letters.C．Because people are more curious about star constellations.D．Because it is illegal to rename the variants with letters.14．What’s the purpose of the passage?A．To introduce new ways of renaming COVID-19 varieties.B．To describe how scientists identified the varieties of COVID-19.C．To explain why some people prefer geography-based names.D．To arouse people’s awareness of more COVID-19 varieties.15．In which part of a magazine could you find this passage?A．Science. B．Travel.C．Sports. D．First Aid.DWelcome to your future life.You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people of your age could live to 150, so, at 40, you aren't old at all. And your parents just had an anti-aging(抗衰老）treatment.Now,all three of you look the same age.You say to your shirt, “Turn red.” It changes from blue to red. In 2035,“smart clothes” contain particles(粒子）much smaller than the cells(细胞）in your body. They can be programmed to change your clothes' color or pattern.You walk into the kitchen. You pick up the milk from the fridge, but a voice says, “You shouldn't drink that!” Your fridge has read the smart chip(芯片）that contains information about the milk, and it knows the milk is old. In 2035,every article of food in the grocery store has such a chip.It's time to go to work. In 2035, cars drive themselves. Just tell your “smart car" where to go. On the way, you can call a friend using your jacket sleeves. Such＂smart technology" is all around you.So will all these things come true?"For new technology to come early,"says scientist Andrew Zolli,“much has to be done so that new things will replace what we have today."The Internet is an example-what will be the next?16．What is the theme of the text?A．The Internet. B．The future life.C．The anti-aging technology. D．The ways of transportation.17．What does the underlined word"They" in Paragraph 3 mean?A．Clothes. B．Cells. C．Colors. D．Particles. 18．Which of the following is TRUE about the "smart car"?A．It can change its color. B．It can tell you where to go.C．You can, just tell it where to go. D．You can call your friend to drive it for you. 19．What does the last paragraph tell us?A．Nothing is impossible.B．Every coin has two·sides.C．Where there is a will, there is a way.D．Never count the chicken before they are hatched(孵化）。

【答案】(1).运动(2).反冲力(3).大一些
【解析】
【详解】力的作用是相互的，物体在施加一个力的同时必定会受到其他物体对它产生的力。气球里的气体喷出时，会产生一个和喷出方向相反的推力，这个力叫反冲力。喷气式飞机、火箭、气垫船都是靠喷气发动机产生的反冲力运动的。要使静止的物体运动起来，必须对物体用力；要使物体运动的更快，必须对物体用更大的力。
10.太阳能热水器中底部的反光材料，能提高吸热效率。（）
【答案】√
【解析】
【详解】太阳能热水器中底部的反光材料可以反射太阳光，使热水器获得更多的光能，提高吸热效率。
