Recently, a British woman used an ancient Chinese invention to help her son 16 a maths problem. Dr Mantri grew up in India. She was taught 17 to use an abacus (算盘) to solve maths problems when she was young. After noticing that her son Dhruv had great difficulty with maths, she started using the same ancient Chinese tool to help him after school. “My son was in Grade 5 when I noticed he was 18 in maths, ” said Dr Mantri. “I would ask him 19 very easy like ‘35－13＝?’, but he couldn’t work it out. ” “I never thought I would use such an old tool to teach him 20 I realized I could try the Chinese abacus. It is a useful 21 to help kids better understand numbers and basic calculations (计算). Very soon I saw the results. After six days, Dhruv started to make progress 22 with the help of the abacus. He even performed with the abacus at a school meeting where some parents came to 23 advice on how to use it to help their kids. ” Known as the fifth invention of ancient China, the Chinese abacus is also 24 as the earliest computer. It helped people solve many maths problems in ancient China. As long as you remember the rules, you can easily use it. Sometimes, just move one bead (算珠), then another bead, and you will get the answer. What a magic tool! The Chinese abacus calculation has been listed 25 an Intangible Cultural Heritage of Humanity (人类非物质文化遗产) since 2013. 16．A．deal with B．part with C．agree with D．compete with 17．A．what B．how C．where D．when 18．A．creative B．weak C．talented D．successful 19．A．something B．anything C．everything D．nothing 20．A．after B．when C．until D．since 21．A．sign B．report C．method D．symbol 22．A．politely B．loudly C．bravely D．rapidly 23．A．care for B．leave for C．ask for D．pay for 24．A．carried B．caught C．covered D．considered 25．A．as B．for C．at D．On 【答案】16．A 17．B 18．B 19．A 20．C 21．C 22．D 23．C 24．D 25．A 【导语】本文主要讲述了一位英国母亲利用中国古老发明算盘帮助儿子解决数学困难，并介绍了算盘的历史及文化地位。 【详解】16．句意：最近，一位英国妇女用一种中国古代发明来帮助她的儿子解决一道数学题。 根据“a maths problem”可知应是deal with“解决”数学题，part with“放弃”，agree with“同意”和compete with“和……竞争”，都与问题搭配不当。 17．句意：她很小的时候就学会了如何使用算盘来解决数学问题。 根据“to use an abacus to solve maths problems”可知应是how“如何、怎样”使用算盘，what“什么”，when“什么时候”和where“在哪里”，不符合语境逻辑。 18．句意：我儿子上五年级的时候，我注意到他数学很差。 根据“had great difficulty with maths”及“couldn’t work it out”可知应是weak“差的、弱的”，creative“有创造力的”，talented“有天赋的”和successful“成功的”，与语境相反。 19．句意：我问他一些非常简单的问题，比如“35－13＝?”，但是他不能算出它。 根据后文的具体例子可知应是something“某事、一些事”，anything“任何事”，everything“每件事”和nothing“没有事”不符合语境，肯定句中用something符合用法。 20． 句意：我从没想过我会用这么古老的工具教他，直到我意识到我可以试试中国算盘。 根据“never thought... realized”可知是一直没有想到……，until“直到”意识到……，after“在……之后”，when“当……时候”和since“自从”，不符合语境。 21． 句意：这是一种帮助孩子更好地理解数字和基本计算的有用方法。 根据“use an ancient invention to help her son”可知应是有用的method“方法”，sign“标志”，report“报告”和symbol“象征”，不符合语境。 22．句意：六天后，Dhruv在算盘的帮助下进步很快。 根据“Very soon I saw the results”可知应是rapidly“快速地”进步，politely“礼貌地”，loudly“大声地”，bravely“勇敢地”，不能修饰“进步”。 23．句意：他甚至在校园会议上现场演示了算盘用法，不少家长都过来请教如何使用算盘帮助他们的孩子。 根据“advice”可知应是ask for“寻求”建议，care for“关心”，leave for“动身去”，pay for“为……付款”，与“建议”搭配不当。 24． 句意：算盘被誉为中国古代第五大发明，它也被视作最早的计算机。 根据“as”和“the earliest computer”可知固定搭配be considered...as“被视作”符合语境，排除carried“携带”，caught“抓住”和covered“覆盖”。 25．句意：中国算盘计算自2013年以来被列为人类非物质文化遗产。 根据“listed... as an Intangible Cultural Heritage”可知be listed as“被列为”符合语境，排除for“为了”，at“在”和on“在……上”。 三、补全对话。(本大题共5小题，每小题1分，共5分) 从选项中选择合适的句子，补全对话。其中有两项多余。 A: Tom, I called you last night, but there was no reply. 26 B: Sorry, Kate!

Scientists have created a brain-spinal chip (芯片) that allows paralyzed(瘫痪的) patients to move their legs, and even walk again. The chip, only 1mm wide, is designed to be fitted into the brain and spinal cord. If the natural communication between the brain and muscles (肌肉) is lost, this chip becomes the bridge. When the chips work, they create a direct connection between the brain and muscles. The results have been amazing. A 34-year-old man, paralyzed after a fall, could move his legs just one day after the operation on January 8, 2025. Two weeks later, he walked five meters with help. Three other patients had similar operations in February and March, all getting better within weeks. Even though the patients’ nervous systems were damaged (受损), the chips helped them walk again. This marks a big step in China’s progress in medical science and it brings hope for over 3.7 million people in China. “This is just the beginning,” Jia, the lead researcher, says. “With the technology,these people may one day leave wheelchairs behind after 3 to 5 years of training.” Behind this achievement is a long journey of careful research and bold thinking.It took the researchers over 10 years to develop the chip. They tested it on animals first,and then on people. They faced many challenges, yet they never gave up. Step by step,they developed a system to reconnect the mind and body in ways once appearing only in science fiction. As the chip continues to improve, it lights a new path forward—one built on science, shaped by care, and aimed toward a brighter future. 36．What do we know about the chips mentioned in the passage? A．They are only as wide as 2 mm. B．They are fitted into the man’s arms. C．They help the patients walk again. D．They improve the patients’ memory. 37．What does the underlined sentence “this chip becomes the bridge” in Paragraph 2 probably mean? A．The chip helps build a new road for the path of medical research. B．The chip connects the brain and muscles when their natural link is broken. C．The chip helps rebuild the path of medical research. D．The chip is made of the same material as a bridge. 38．What is the writer’s main reason for writing this passage? A．To recommend a science story. B．To report a pioneer doctor in medicine. C．To compare different treatments. D．To introduce a new medical success. 39．What can we infer about the research process of the brain-spinal chip? A．It was completed in a short time with no difficulties. B．The researchers tested the chip on humans first. C．It took more than a decade and faced many challenges. D．The researchers gave up several times due to difficulties. 40．What would be the best title of this passage? A．China’s Chips Bring New Hope B．Future of China’s Medical Science C．Science Fiction Changes Our Lives D．Challenges for Chinese Scientists 【答案】36．C 37．B 38．D 39．C 40．A 【导语】本文主要介绍了中国的一项医学新突破（或医学新成功），即一种能帮助瘫痪患者重新行走的脑脊髓芯片，它为脊髓损伤患者带来了新的希望。 【详解】36．根据第一段第二句“Scientists have created a brain-spinal chip… that allows paralyzed patients to move their legs, and even walk again.”可知，这种芯片能帮助瘫痪患者活动腿部甚至再次行走。选项C“他们帮助患者重新行走。”符合题意。 37．根据第二段画线句后的“When the chips work, they create a direct connection between the brain and muscles.”可知，当大脑和肌肉之间的自然联系丢失时，芯片起到了连接作用，即成为“桥梁”。选项B“当大脑与肌肉之间的自然联系中断时，该芯片可连接二者。”解释了这一含义。 38．通读全文可知，文章主要报道了中国在脊髓损伤治疗方面的一项医疗突破（脑脊髓芯片）及其带来的成果和希望，旨在介绍这一新的医学成功。选项D“介绍一项新的医学成果。”符合主旨。 39．根据第五段“It took the researchers over 10 years to develop the chip.”以及“They faced many challenges, yet they never gave up.”可知，研发过程耗时超过10年（即超过一个decade）且面临许多挑战。选项C“耗时十余年，面临诸多挑战”符合题意。 40．文章首段提到“A medical breakthrough in China is giving new hope…”，全文围绕中国研发的芯片为脊髓损伤患者带来行走的新希望展开。选项A“中国的芯片带来新希望”最能概括文章中心。 五、单词拼写。(本大题共10小题，每小题1分，共10分) 41．The car ________ (speed) up when it left the town. 【答案】sped 【详解】句意：这辆车驶出城镇时加速了。本句由when引导时间状语从句，从句动词left是leave的过去式，时态为一般过去时，主句动作与从句同步发生，主句也要使用一般过去时，speed的过去式为sped。 42． Students feel ________ (inspire) to create and invent new things. 【答案】inspired 【详解】句意：学生们受到鼓舞去创造和发明新东西。‑ed形容词修饰人，表示“感到……”；‑ing形容词修饰事物。主语“Students”是人，用inspired（受鼓舞的）。 43． We should be ________ (有创造力的) and dare to think differently. 【答案】creative 【详解】句意：我们应该有创造力，敢于与众不同地思考。“有创造力的”可译为creative，形容词作表语。 44． Edison was a great ________ (invent), and he had many great ________ (invent). 【答案】 inventor inventions 【详解】句意：爱迪生是一位伟大的发明家，他有许多伟大的发明。invent是动词，表示“发明”。第一空指人，“a”后接可数名词单数，invent应变为inventor，表示“发明家”；第二空指物，“had many”后接名词复数，invent变为名词复数inventions。表示“发明”。 45． This machine can ________ (生产) thousands of bottles every day. 【答案】produce 【详解】句意： 这台机器每天能生产数千个瓶子。中文提示“生产”对应 produce；空格前是情态动词“can”，空格处应填动词原形。 46． This technology is ________ (广泛地) used. 【答案】widely 【详解】句意：这项技术被广泛应用。修饰动词used要用副词，“广泛地”对应的副词是widely。 47． This place is not ________ (合适的) for camping. 【答案】suitable 【详解】句意：这个地方不适合露营。根据汉语提示“合适的”，应填形容词suitable，作表语，且常与for搭配表示“适合……”。 48． You will ________ (收获) success through hard work. 【答案】gain 【详解】句意：你将通过努力工作获得成功。gain“收获”，动词；will后用动词原形，故填gain。 49． Please press the blue ________ (按钮) to turn it off. 【答案】button 【详解】句意：请按下蓝色按钮，将它关闭。根据汉语提示可知，button“按钮”。句中指“这一个蓝色按钮”，是单数概念，因此填名词单数button即可。 50． Everyone should be ________ (response) for their own actions. 【答案】responsible 【详解】句意：每个人都应该对自己的行为负责。空格前有“be”，需填形容词作表语。所给词“response”为名词，其形容词形式为“responsible”，构成固定搭配“be responsible for”，意为“对……负责”。故填responsible。 六、完成句子。(本大题共5小题，每小题2分，共10分) 51．他的想法导致了多种尺寸和颜色的便利贴的生产。 His idea ________ ________ the production of sticky notes of many sizes and colours. 【答案】led to 【详解】原句中“导致了”是关键信息，表示“导致”用lead to，描述过去发生的事件，用一般过去时，lead的过去式是led。应填led to。 52．所有的原料被混合在一起并在水中煮沸。 All the ingredients ________ ________ and boiled in water. 【答案】were mixed 【详解】原句中“被混合”是关键词，表示“混合”用动词mix，“被”提示用被动语态，根据boiled，可知用一般过去时的被动语态描述过去发生的动作，主语“ingredients”是复数，谓语结构用“were+动词的过去分词”，mix的过去分词直接在词尾加-ed。 53．所有食物都由机器本身添加。 All the food ________ ________ by the machine itself. 【答案】is added 【详解】原句中的“添加”是关键词，表示“添加”用add，此处表示所有的食物被添加，用被动语态，主语all the food是不可数名词，谓语用第三人称单数形式，助动词用is，构成被动语态is added。 54．广府是一个美丽的城镇，有数百栋明代和清代的古老建筑。 Guangfu is a beautiful town with ________ ________ old buildings from the Ming and Qing dynasties. 【答案】hundreds of 【详解】原句中“数百”是关键词，表示“数百的”固定短语是“hundreds of”，后接可数名词复数。空格后为“old buildings”复数名词。故填hundreds；of。 55．每个人在公共场合都应当遵守规则、尊重他人。 Everyone is ________ ________ follow the rules and respect others in public. 【答案】supposed to 【详解】原句中“应当”是关键词，表示“应当做某事”的短语是“be supposed to do sth.”，故填supposed；to。 七、选词填空。(本大题共10小题，每小题1分，共10分) dream  which  save  though  in  support  companies  seriously  offer  worldwide Have you ever dreamed of flying over traffic jams?

Scientists have created a brain-spinal chip (芯片) that allows paralyzed(瘫痪的) patients to move their legs, and even walk again. The chip, only 1mm wide, is designed to be fitted into the brain and spinal cord. If the natural communication between the brain and muscles (肌肉) is lost, this chip becomes the bridge. When the chips work, they create a direct connection between the brain and muscles. The results have been amazing. A 34-year-old man, paralyzed after a fall, could move his legs just one day after the operation on January 8, 2025. Two weeks later, he walked five meters with help. Three other patients had similar operations in February and March, all getting better within weeks. Even though the patients’ nervous systems were damaged (受损), the chips helped them walk again. This marks a big step in China’s progress in medical science and it brings hope for over 3.7 million people in China. “This is just the beginning,” Jia, the lead researcher, says. “With the technology,these people may one day leave wheelchairs behind after 3 to 5 years of training.” Behind this achievement is a long journey of careful research and bold thinking.It took the researchers over 10 years to develop the chip. They tested it on animals first,and then on people. They faced many challenges, yet they never gave up. Step by step,they developed a system to reconnect the mind and body in ways once appearing only in science fiction. As the chip continues to improve, it lights a new path forward—one built on science, shaped by care, and aimed toward a brighter future. 36．What do we know about the chips mentioned in the passage? A．They are only as wide as 2 mm. B．They are fitted into the man’s arms. C．They help the patients walk again. D．They improve the patients’ memory. 37．What does the underlined sentence “this chip becomes the bridge” in Paragraph 2 probably mean? A．The chip helps build a new road for the path of medical research. B．The chip connects the brain and muscles when their natural link is broken. C．The chip helps rebuild the path of medical research. D．The chip is made of the same material as a bridge. 38．What is the writer’s main reason for writing this passage? A．To recommend a science story. B．To report a pioneer doctor in medicine. C．To compare different treatments. D．To introduce a new medical success. 39．What can we infer about the research process of the brain-spinal chip? A．It was completed in a short time with no difficulties. B．The researchers tested the chip on humans first. C．It took more than a decade and faced many challenges. D．The researchers gave up several times due to difficulties. 40．What would be the best title of this passage? A．China’s Chips Bring New Hope B．Future of China’s Medical Science C．Science Fiction Changes Our Lives D．Challenges for Chinese Scientists 五、单词拼写。(本大题共10小题，每小题1分，共10分) 41．The car ________ (speed) up when it left the town. 42． Students feel ________ (inspire) to create and invent new things. 43． We should be ________ (有创造力的) and dare to think differently. 44． Edison was a great ________ (invent), and he had many great ________ (invent). 45． This machine can ________ (生产) thousands of bottles every day. 46． This technology is ________ (广泛地) used. 47． This place is not ________ (合适的) for camping. 48． You will ________ (收获) success through hard work. 49． Please press the blue ________ (按钮) to turn it off. 50． Everyone should be ________ (response) for their own actions. 六、完成句子。(本大题共5小题，每小题2分，共10分) 51．他的想法导致了多种尺寸和颜色的便利贴的生产。 His idea ________ ________ the production of sticky notes of many sizes and colours. 52．所有的原料被混合在一起并在水中煮沸。 All the ingredients ________ ________ and boiled in water. 53．所有食物都由机器本身添加。 All the food ________ ________ by the machine itself. 54．广府是一个美丽的城镇，有数百栋明代和清代的古老建筑。 Guangfu is a beautiful town with ________ ________ old buildings from the Ming and Qing dynasties. 55．每个人在公共场合都应当遵守规则、尊重他人。 Everyone is ________ ________ follow the rules and respect others in public. 七、选词填空。(本大题共10小题，每小题1分，共10分) dream  which  save  though  in  support  companies  seriously  offer  worldwide Have you ever dreamed of flying over traffic jams?

Scientists have created a brain-spinal chip (芯片) that allows paralyzed(瘫痪的) patients to move their legs, and even walk again. The chip, only 1mm wide, is designed to be fitted into the brain and spinal cord. If the natural communication between the brain and muscles (肌肉) is lost, this chip becomes the bridge. When the chips work, they create a direct connection between the brain and muscles. The results have been amazing. A 34-year-old man, paralyzed after a fall, could move his legs just one day after the operation on January 8, 2025. Two weeks later, he walked five meters with help. Three other patients had similar operations in February and March, all getting better within weeks. Even though the patients’ nervous systems were damaged (受损), the chips helped them walk again. This marks a big step in China’s progress in medical science and it brings hope for over 3.7 million people in China. “This is just the beginning,” Jia, the lead researcher, says. “With the technology,these people may one day leave wheelchairs behind after 3 to 5 years of training.” Behind this achievement is a long journey of careful research and bold thinking.It took the researchers over 10 years to develop the chip. They tested it on animals first,and then on people. They faced many challenges, yet they never gave up. Step by step,they developed a system to reconnect the mind and body in ways once appearing only in science fiction. As the chip continues to improve, it lights a new path forward—one built on science, shaped by care, and aimed toward a brighter future. 36．What do we know about the chips mentioned in the passage? A．They are only as wide as 2 mm. B．They are fitted into the man’s arms. C．They help the patients walk again. D．They improve the patients’ memory. 37．What does the underlined sentence “this chip becomes the bridge” in Paragraph 2 probably mean? A．The chip helps build a new road for the path of medical research. B．The chip connects the brain and muscles when their natural link is broken. C．The chip helps rebuild the path of medical research. D．The chip is made of the same material as a bridge. 38．What is the writer’s main reason for writing this passage? A．To recommend a science story. B．To report a pioneer doctor in medicine. C．To compare different treatments. D．To introduce a new medical success. 39．What can we infer about the research process of the brain-spinal chip? A．It was completed in a short time with no difficulties. B．The researchers tested the chip on humans first. C．It took more than a decade and faced many challenges. D．The researchers gave up several times due to difficulties. 40．What would be the best title of this passage? A．China’s Chips Bring New Hope B．Future of China’s Medical Science C．Science Fiction Changes Our Lives D．Challenges for Chinese Scientists 五、单词拼写。(本大题共10小题，每小题1分，共10分) 41．The car ________ (speed) up when it left the town. 42． Students feel ________ (inspire) to create and invent new things. 43． We should be ________ (有创造力的) and dare to think differently. 44． Edison was a great ________ (invent), and he had many great ________ (invent). 45． This machine can ________ (生产) thousands of bottles every day. 46． This technology is ________ (广泛地) used. 47． This place is not ________ (合适的) for camping. 48． You will ________ (收获) success through hard work. 49． Please press the blue ________ (按钮) to turn it off. 50． Everyone should be ________ (response) for their own actions. 六、完成句子。(本大题共5小题，每小题2分，共10分) 51．他的想法导致了多种尺寸和颜色的便利贴的生产。 His idea ________ ________ the production of sticky notes of many sizes and colours. 52．所有的原料被混合在一起并在水中煮沸。 All the ingredients ________ ________ and boiled in water. 53．所有食物都由机器本身添加。 All the food ________ ________ by the machine itself. 54．广府是一个美丽的城镇，有数百栋明代和清代的古老建筑。 Guangfu is a beautiful town with ________ ________ old buildings from the Ming and Qing dynasties. 55．每个人在公共场合都应当遵守规则、尊重他人。 Everyone is ________ ________ follow the rules and respect others in public. 七、选词填空。(本大题共10小题，每小题1分，共10分) dream  which  save  though  in  support  companies  seriously  offer  worldwide Have you ever dreamed of flying over traffic jams?

However, I believe depending on it is harmful.     Firstly, it makes students lazy and stop thinking by themselves. If we depend on phones too much, our brains will not work actively. Secondly, some wrong answers online may mislead students. We might learn incorrect knowledge which is bad for study. Finally, relying on online answers is harmful to exams because we cannot use phones then.     In my opinion, we should try to solve problems independently. Only in this way can we truly improve ourselves and get better grades in the future.　 原创精品资源学科网独家享有版权，侵权必究！1 学科网（北京）股份有限公司1 / 2 学科网（北京）股份有限公司 $
