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：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.

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 ...

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.

Daniels is the only man in the world who designs his own watches makes all the pars himself and then puts them together.A Daniels watch is the product of his hands alone. One of his watches which is now in an American museum took 3500 hours to complete. He usually makes one watch a year. Each one is inscribed (刻) with “Daniels London” and costs about $10,000. Of course these are not ordinary watches —they are very beautiful and will last three centuries.George Daniels has always been attracted by clocks and watches. When he was five he used t o take his father’s clock apart and put it back together again. At school he used to repair his teachers watches.He is now internationally famous and many people would like him to make watches for them. But most of them will be disappointed. He chooses his customers very carefully indeed. It must be someone who understands the subject,” he says “not someone who will leave the watch in the drawer and only show it to dinner quests.” 1．Who is George Daniels?A ．One of the few who repaired watches in the old days.B ．The only man who collects old watches in the world.C ．One of the few remaining watch designers in the world.班级_____________ 姓名_____________ 考生号_____________ 考场号_____________D．The only man who designs and makes watches by himself.2．How long can a Daniels watch keep working?A．10,000 hours.

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）。
