B 14-year-old Leanne Fan from San Diego, California, was named the grand prize winner of the 2022 3M Young Scientist Challenge, the nation’s top middle school science competition. Leanne Fan developed the Finsen Headphones, a low-cost headphone device that uses machine learning and blue light therapy (疗法) to detect and treat mid-ear infections (感染) in children — potentially preventing up to 60% of hearing loss in children. The world sees 700 million cases of mid-ear infections every year. Fan hopes that this can be an effective and low-cost treatment option for the thousands who are affected. Fan was inspired to create the headphones three years ago while learning about Niels Finsen, who won the Nobel Prize in 1903 after inventing light therapy to treat bacterial (细菌的) infections. “I thought, ‘This is an amazing idea, and I can apply it to something else in my daily life,’” Fan said. Fan took home the top prize, earning the title of “America’s Top Young Scientist” and $25,000. She is planning to use some of the prize money to start the patent process for the headphones. Fan is optimistic that the Finsen Headphones will be able to help people in the near future. “Being part of the 3M Young Scientist Challenge was absolutely the best part of my year,” Fan said. “I could meet scientists that are my age and going for their dreams too, and made some friends.” She hopes to inspire other girls who want to become inventors. “Even a small idea can go far,” she said. “I had an idea to use blue light to kill bacteria and three years later, I’m here.” 4．What is the second paragraph mainly about? A．The cost of the headphone device. B．The process of blue light therapy. C．The description of the headphones. D．The cases of mid-ear infections. 5．What inspired Leanne Fan to create the headphones? A．Her own daily life. B．Her desire for the Nobel Prize. C．The facts of bacterial infections. D．Niels Finsen’s invention of light therapy. 6．Which of the following can best describe Fan? A．Outgoing. B．Patient. C．Creative. D．Hardworking. 7．What can we learn from Fan’s story? A．Even a small idea can go far. B．Many hands make light work. C．Roses given, fragrance in hand. D．Actions speak louder than words. C What if you could experience music in your body, rather than hear it through your ears? That’s the idea behind Patrick Hanlon’s magic vests, which allow concertgoers who are deaf or hard of hearing to experience music. A magic vest is a wearable device that allows its user to experience touch through force, vibration and movement. Hanlon is a co-founder of Music: Not Impossible, an arm of Not Impossible Labs. This group creates and uses tech to try to transcend social barriers, including those around disability. Magic vests will promote inclusivity at live music performances. Previous methods that deaf and hard-of-hearing individuals would use to enjoy live music included putting their hands on speakers. They could also hold a balloon to feel vibrations on their fingertips. The vests aim to allow for a totally new experience. Hanlon says that nobody expects that using the vests will be so engaging, and “when you see it in people’s eyes, it’s magical. ” Jay Zimmerman, a composer whose ability to hear was damaged, says the vests are an example of new technology offering more exciting flexibility than before. He hopes that soon these inventions will allow deaf kids to have experiences with real vibrations. The vests are not limited to any particular type of music. Hanlon explained the vibration points can even be adjusted to fit a show’s overall atmosphere. The vests have been used at concerts for rock band Greta Van Fleet and pop star Lady Gaga. 8．What is the purpose of Patrick Hanlon’s magic vests? A．To perfectly fit a concert’s overall atmosphere. B．To help people with hearing problems feel music better. C．To provide better seating options at live music events. D．To replace traditional speakers at music concerts. 9．How do the vests allow users to experience different musical elements? A．By putting hands on speakers. B．By holding a balloon. C．By engaging in magic. D．By feeling force, vibration and movement. 10．What does the underlined word “transcend” in paragraph 2 most probably mean? A．Get over. B．Cure of. C．Tear up. D．Account for. 11．Where might the text be taken from? A．A musical comedy. B．A science magazine. C．A concert advertisement. D．A research report. D Scientists have crafted a novel substance derived from the collagen protein found in pig skin, which closely mimics the structure of the human cornea. This breakthrough has already restored vision to 20 individuals, offering a beacon of hope for those afflicted with corneal blindness. Approximately 12.7 million individuals globally are visually impaired or blind due to corneal damage or disease. The conventional solution for vision restoration is a corneal transplant from a human donor. However, the odds of receiving such a transplant are slim, with only one in 70 patients benefiting from this procedure. Moreover, the majority of these patients reside in nations with lower to middle incomes, where access to such treatments is severely restricted. To counteract the limitations inherent in traditional corneal treatments, researchers have harnessed the collagen protein from pig skin. "We can create a biocompatible material that fulfills all the requirements for human implantation, capable of being produced in large quantities to aid a broader spectrum of individuals facing vision impairment," stated Professor Neil Lagali. Unlike donated corneas, which have a short shelf life of two weeks, these bioengineered corneas can be preserved for up to two years, enhancing their practicality. The pig skin, a byproduct of the food industry, is readily available, further simplifying the process. Innovative surgical techniques have been developed in tandem with this material, eliminating the need for sutures in the procedure. In an initial trial, 14 out of the 20 subjects were completely blind prior to the surgery. Remarkably, after a period of two years, all patients experienced a return of their sight. Among them, three Indian participants who had been blind achieved full visual acuity post-operation. The research team is eager to explore the potential applications of this technology for treating a wider array of eye conditions and is investigating the possibility of customizing the implants to individual patients, thereby increasing their efficacy even further. 12．What is the disadvantage of traditional cornea treatment? A．Serious side effects. B．Low availability rate. C．Poor medical equipment. D．Complicated surgical process. 13．What do we know about the biomaterial? A．It has higher production costs. B．It can be stored for much longer. C．It is able to be used for several times. D．It can help people prevent vision problems. 14．Which of the following best describes the new surgical method? A．Successful. B．Ineffective. C．Convenient. D．Controversial. 15．What is the main purpose of the text? A．To spread knowledge about cornea donation. B．To show the difficulties of treating blindness. C．To call on people to protect their eyes properly. D．To present a new breakthrough in the medical field. 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。选项中有两项为多余选项。 5G will be the lifeblood of the new economy. Self­driving cars, virtual reality, smart cities and networked robots will all be powered by 5G networks. Like every “next generation” wireless network technology, 5G will give your phone a speedier connection — up to 100 times faster than 4G. 16 On 4G, it would take six minutes. 5G’s extra bandwidth will make service more reliable, allowing more devices to connect to the network at the same time. 17 Sensors, computers, cars, robots, and other new technology will all connect to 5G one day. Today’s 4G networks don’t have the bandwidth for the vast amounts of data all those devices will transmit. To accomplish all that, much of the 5G network will travel over super­high­frequency airwaves. These higher frequencies bring faster speeds and more bandwidth. 18 That means wireless companies will need to install thousands — perhaps millions — of small cell towers on top of lamp posts, on the side of buildings and inside homes. 19 In buildings and in crowded areas, 5G might provide a speed boost, but 4G will still be used to cover wider areas for the time being. 5G networks will also reduce to virtually zero the latency (延迟), or lag time, between devices and the servers they communicate with. Zero latency can allow self­driving cars to process all the information they need to make life­or­death decisions in the blink of an eye. 20 Those innovations will only be possible if the communication between a network and a device is seamless (无缝的)． A．5G will open the door to the future. B．That’s why 5G will not completely replace 4G. C．But 5G is about much more than smartphones. D．That’s enough to download a 3D movie in 3 seconds. E．5G is more than faster speeds and faster connections indeed. F．But they can’t travel through walls and they get weaker over long distances. G．It’s believed that 5G could help power the next generation of long­distance operations. 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。 When searching for a science fair project, many children scratch (挠) their heads.

I’m Ben, your future self! I know that you are really worried about your future career, so I wanted to write this letter to put your mind at rest. On the one hand, in the future, computers will be incredibly smart, so they can help you — a chef working at a fancy restaurant a lot. You will mix and cook virtual ingredients on a virtual screen while a robot will do all the real work for you. On the other hand, computers will still lack creativity. They cannot come up with recipes for new and exciting dishes, so you need to create new dishes by yourself, which will be your main work. In fact it imposes higher requirements on chefs. You will have to be very creative and keep trying. All in all, I think you will be happy with your future job, because we both like to eat! So stop worrying. Your future will be great. Trust me! Best regards, Future Ben 【导语】本篇书面表达属于应用文。设想未来50岁的你得知现在的你为未来职业而焦虑，要求考生给现在的自己写一封信。 【详解】1.词汇积累 担心的：worried→concerned 高兴的：happy→delighted 提出：come up with→put forward 总之：all in all→in short 2.句式拓展 合并简单句 原句：In fact it imposes higher requirements on chefs.

The girl was sitting behind the bushes, sobbing. Although in the darkness Jim could hardly see the girl clearly, he could certainly sense her trembling with fear. Not wanting to frighten the girl further, Jim at first spoke to her from a distance. Jim said soothingly that the attacker had run away and she was safe. There was a long pause and then he heard some words from the girl. “Dad, is that you?” asked the girl in wonder and amazement as she walked from behind the bushes. To Jim’s shock, there stood Jim’s youngest daughter, who began crying. Hugging his daughter, Jim also cried. After the police arrived, they told them something about the attacker in detail. He felt it was a right decision to rush to fight with the attacker. Now in his daughter’s eyes, Jim is a brave man and a hero without fearing any danger. 【导语】本文以人物为线索展开，讲述了，深夜，吉姆走在灯光昏暗的街道上；当他静静地走着的时候，吉姆听到灌木丛后面传来低沉的尖叫声。就在离吉姆站的地方几码远的地方，一个女孩正在被袭击。他决定帮助那个女孩，与袭击者搏斗的故事。 【详解】1.段落续写： ①由第一段首句内容“看着袭击者跑进黑暗中，吉姆想起了那个女孩。”可知，第一段可描写吉姆安慰那个女孩。 ②由第二段首句内容““爸爸，是你吗?”女孩从灌木丛后面走出来，惊奇地问道。”可知，第二段可描写吉姆认出那个女孩是自己的女儿。 2.续写线索：看着袭击者跑进黑暗——朝女孩走去——安慰女孩——女孩认出吉姆是爸爸——抱着女孩哭了——女儿认为吉姆是最勇敢的人 3.词汇激活 行为类 奔跑：run/ rush 走向：walk toward/ move toward 颤抖：tremble/ shake 情绪类： 哭泣：cry/ weep 【点睛】[高分句型1] Breathing hard, Jim rose from the ground and walked towards her.（运用了现在分词作状语） [高分句型2] Jim said soothingly that the attacker had run away and she was safe.（运用了that引导的宾语从句与过去完成时） 答案第1页，共2页 答案第1页，共2页 学科网（北京）股份有限公司 $$
