I am writing to share a personally effective method: mindful walking. I dedicate fifteen minutes each evening to a walk in the schoolyard, consciously engaging in the surroundings. The goal is not to reach a destination, but to guide my mind back whenever it wanders to worries. I sincerely invite my fellow students to try this simple yet powerful technique, and I am confident it can bring you similar peace and clarity. Yours, Li Hua 47．Possible version I could no longer hold back the flood of sad tears. Choking on my sobs, I confessed everything — how my mind went blank on stage, how the teacher replaced me, and how ashamed I felt. “I’ve failed you after all our practice,” I cried. My mother gently wiped my cheeks and pointed back to the dandelions. “You see,” she said softly, “I never thought of removing them because every flower has its own beauty. The roses are the stars, but the dandelions hold the story together — just like a narrator. Their quiet beauty doesn’t take away from the roses; it completes the garden.” Her words slowly eased the tightness in my chest. I looked again at the humble white flowers, no longer seeing them as weeds, but as gentle storytellers nestled among the stars. “You will be an excellent narrator,” Mom said, holding my hands. “Your voice is clear and warm, and you understand the heart of the story better than anyone.” Inspired, I devoted myself to the new role. On the night of the performance, I stood at the side of the stage, script in hand. As I began to speak, my voice, calm and confident, flowed through the auditorium, guiding the audience through the story. When the curtain fell, my teacher praised me, saying the narration had moved everyone. I finally understood that every role, like every flower, has its own unique beauty and value. That day, I learned that shining isn’t only about being the rose in the spotlight — it’s also about being the dandelion that tells the story with quiet grace. 答案第4页，共7页 学科网（北京）股份有限公司 $ 石嘴山市第一中学2025-2026学年第二学期高二年级期中考试 英语试题 听力（满分 30 分） 阅读（共两节，满分 50 分） 第一节（共 15 小题;每小题 2. 5 分，满分 37. 5 分） 阅读下列短文，从每题所给的 A、B、C、D 四个选项中选出最佳选项。 A F.

B Dr Nicola Patron’s office is a little different. Near the window hangs a modern artwork of the plant Nicotiana benthamiana, a host on which to grow medicinal or agriculturally useful substances. Here is where engineering, biology and art overlap (重叠). Despite her green fingers, Nicola’s childhood dream was to become an astrophysicist. At 17, she joined a science programme that invited students to grow and observe seeds flown to the International Space Station. “It was the first experimental data I ever had. It’s so fun,” she says. “Meanwhile, I was volunteering for a homeless charity, which made me think about food security and distribution. The combination of these two things shifted what I wanted to do: biological sciences suddenly seemed relevant.” Young Nicola was a few years early for the birth of bioengineering, but technology has since caught up with her ideas. Nicola can now apply engineering principles to biological systems, and guide how plant genes (基因) are expressed. Her lab is working on fungal-resistant (抗真菌的) crops. This resistance is determined by a gene network, where genes regulate each other in a complex process. To speed up this search, Nicola cooperates with mathematicians. Candidate genes can be tested in mathematical models to predict their impact on characteristics like growth and resistance. Finally, Nicola can work on encoding promising genes into a piece of DNA．If proven effective, this could be transformative for food security. In another part of Nicola’s work, she’s trying to identify sustainable ways to produce plant-based medicines. Some medically useful plants aren’t easy to mass produce, making the drug expensive. Fortunately, biologists can program another organism to produce it with high efficiency and low cost. That’s what Nicola is doing with Nicotiana benthamiana. She describes the process as “reading nature’s blueprints and directing its energy to more powerful ends.” 4．What motivated Nicola to pursue biological sciences? A．Her childhood dream of being an astrophysicist. B．Her natural talent for growing seeds from space. C．Her big ideas of combining engineering and biology. D．Her experience in scientific projects and charity work. 5．Why does Nicola use mathematical models in her research? A．To clarify the research process. B．To help select the promising genes. C．To balance growth and resistance. D．To address food security challenges. 6．What is Nicola’s belief in medicinal development? A．Nature should be viewed as a guideline. B．High efficiency should be achieved at all costs. C．Ways should be found to mass produce plants. D．Priority should be given to cost-effective plants. 7．What can we learn about Nicola? A．She was good at art and design. B．Her pioneering idea has been applied. C．She has concerns about drug safety. D．Her inquiring mind drives her to explore. C Octopuses can do many things, from their well-known ability to hide to throwing shells at other octopuses, but one important thing they can’t do is control their body temperature. However, a study in the journal Cell shows that two-spot octopuses adapt to seasonal temperature change by producing different neural proteins. They complete this by editing their RNA to protect their brains. Humans have millions of editing sites, that affect less than three percent of our genes, but the smart cephalopods (头足类动物) can reprogram most of their neural proteins. “In the context outside of cephalopods, the main way to get a new kind of protein is through mutation and evolution,” says St. Francis University biologist Matthew Birk. “That takes generations and hundreds and thousands of years, while this is days. That was very exciting.” Researchers worked with California two-spot octopuses in a laboratory setting and in the wild. Adjusting wild-caught adult octopuses to warm (71.6F) or cold (55.4F) waters in tanks for several weeks, they made a comparison, finding that so many proteins and so many editing sites had changed upon temperature change, and almost all of them in the same direction. Editing occurred at around 30 percent or more than 20,000 individual places on the genome. The edited proteins tended to be neural proteins, and almost all edited sites sensitive to temperature swings were more highly edited in the cold. The team also investigated if reprograming impacted protein structure function. They focused on two proteins that are critical for nervous system function. They found evidence that the reprograming changed the structures in the proteins that would impact how they function. “I’m really interested to see if this extends beyond physical environmental factors. If social context can influence the way you change your nervous system, that’s a pretty interesting concept,” says biologist Rosenthal. “I want to know what is behind the high-level rewriting of RNA．” 8．What ability of octopuses is mentioned in the journal Cell? A．Nerve hiding. B．RNA rewriting. C．Territory occupying. D．Temperature controlling. 9．What is the excitement about cephalopods for Matthew Birk? A．Displaying very fast reactions B．Having great reproductive capacity. C．Showing unique evolutionary processes. D．Updating neural proteins efficiently. 10．What did the researchers find about octopuses from their experiment? A．They edited genes more in the cold. B．They kept original structures of proteins. C．They changed all types of proteins. D．They showed no activity in warm waters. 11．What do researchers want to explore further about octopuses? A．Elements of their protein structures. B．Other reasons for their gene editing. C．Proteins role in their nervous system. D．Temperature impacts on their behavior. D March 13, 2025—Chinese scientists have made history by creating ultra-thin metal sheets that are 200,000 times thinner than a human hair. This breakthrough, led by researchers from the Chinese Academy of Sciences, opens a new chapter in materials science and is likely to revolutionize future technologies such as smartphones, medical devices, and clean energy systems. Metals are generally difficult to shape at the atomic level because their atoms bond tightly in all directions, much like a tightly packed “compressed biscuit” (压缩饼干). To address this issue, the team developed a method called van der Waals squeezing (范德华挤压). Picture melting metal and pressing it between two ultra-smooth layers of molybdenum disulfide (二硫化钼), a material similar to pencil lead but with an atomically flat surface. These layers function like a perfect mold, squeezing the metal into sheets that are just one atom thick. What’s the outcome? Stable two-dimensional metals such as bismuth (铋), tin (锡), and lead (铅) that remain intact even after a year. These two-dimensional metals could give rise to smaller and faster electronics. For instance, a single layer of bismuth conducts electricity ten times better than ordinary bismuth and can be controlled by tiny voltage changes, making it an ideal choice for low-power computer chips. They may also make it possible to have transparent screens on windows or glasses and ultra-sensitive medical sensors for the early detection of diseases. What’s even more thrilling is that this discovery fills a gap in the family of two-dimensional materials. Since the discovery of graphene (石墨烯) (a two-dimensional carbon sheet) in 2004, scientists have produced hundreds of two-dimensional materials, but two-dimensional metals were absent until now. As Dr. Zhang Guangyu, the leading scientist, put it, “Just as three-dimensional metals shaped ancient civilizations, two-dimensional metals could drive the next technological revolution.” This achievement didn’t come easily. The team spent years perfecting the method and even built their own equipment to cut costs. Their perseverance paid off, as international experts hailed this work as a “major leap” in the field of science. 12．What is the main achievement of the Chinese scientists mentioned in the text? A．Creating a new type of pencil lead using molybdenum disulfide. B．Developing a method to recycle old smartphones more efficiently. C．Producing ultra-thin 2D metals 200,000 times thinner than a human hair. D．Discovering a way to turn graphite into transparent screens. 13．Why is the new 2D bismuth significant for electronics? A．It can store solar energy for months without degradation. B．It conducts electricity 10 times better than regular bismuth. C．It replaces graphene in all existing electronic devices. D．It allows computers to operate without any power source. 14．What challenge did the scientists face in creating 2D metals according to the text? A．Metals naturally form weak bonds in all directions. B．Existing equipment was too expensive to use. C．Metals resemble “compressed biscuits” in atomic structure. D．Transparent screens required rare materials. 15．The comparison between 3D metals shaping ancient civilizations and 2D metals driving future revolutions is used to: ________. A．highlight the historical importance of metal tools. B．explain why graphene was a failed experiment. C．criticize the slow progress of modern technology. D．emphasize the transformative potential of the discovery. 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。 On Aug. 7, 2021, Xu Shixiao and her partner, Sun Mengya, won gold in the first women’s canoe double 500 m event at the Tokyo Games. It was also the first Olympic gold medal for China in the event. 16 Xu was born in a small county in a mountainous area in Jiangxi. Before becoming a paddler, Xu couldn’t even swim since her hometown is surrounded by mountains. In 2005, the 13-year-old, who was much taller than her peers, attracted the attention of a rowing coach who came to look for potential paddlers in her school. 17 “Every day my canoe turned over dozens of times. I drank lots of water in rivers,” recalls Xu of her first canoeing training. Xu kept training for a year and she made the final of a national race for teenage athletes out of a dozen paddlers at the centre. In 2013, the news that women’s canoeing was still not an Olympic event dealt her a heavy blow. 18 Xu gave up her career and found her first job as a saleswoman in a furniture company. When Xu Shixiao went to work as usual in the furniture company five years ago, she was surprised to get a call from her former coach, inquiring about her willingness to return to canoeing and compete in the Tokyo Olympic Games. 19 “I never thought that one day I could go back to the sport. Now that I have started again, I will do my best,” says Xu. 20 She is also looking forward to taking part in the Paris Olympics in 2024. A．Xu quickly made her decision. B．Yet Xu’s journey to the Olympics was a rough one. C．It was impossible for her to change the sport at age 21. D．She made all efforts to reach the goal and never gave up. E．Xu agreed to train at a rowing centre because she thought rowing a boat was fun. F．Compared with athletes who are in their early 20s, Xu’s physical recovery is slower. G．The Olympic medalist will participate in competitions at home and abroad this year. 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 四个选项中选出最佳选项。 London life for Cathy Hagner and her three children is set to be permanent.

It uses AI to accurately predict how genes work in different plant parts and types of crops. This is very useful because crops like wheat have a 38 (remarkable) large set of genetic materials — about 40 times 39 (big) than rice’s, and five times the size of humans’. 40 (address) this complexity, the team built two core models into one tool. DeepWheat can find out how changing genes 41 (affect) plants and predict these changes clearly. Many crop genes can influence multiple traits (特征), sometimes in good ways and sometimes in bad ones. For example, 42 rice gene might increase the number of flowers but weaken the stems (茎) if it’s too active. Current gene-editing relies on tiring, blind trial and error. DeepWheat offers a better alternative: systems that enable researchers to keep 43 (run) computer simulations (模拟) for testing all possible gene changes let them spot useful adjustments before real experiments, improving precision and saving effort. Successfully 44 (test) in rice and corn, the tool has proved effective for many crops. It identifies key parts, improves editing targets, and solves a farming bottleneck — when improving one trait weakens another. By making better gene networks, DeepWheat reduces such trade-offs, speeds up good trait combination, and serves 45 a practical AI solution for developing high-quality crops. 三、写作 46．假定你是李华，你校英文广播站“Stress-relieving Tips”专栏正在向高三学生征集稿件。请你给栏目编辑写一封邮件投稿，内容包括： (1)你的解压方法； (2)说明理由。 注意： (1)写作词数应为80个左右； (2)请按如下格式在答题卡的相应位置作答。 Dear Editor, _______________________________________________________________________________   Yours, Li Hua 47．阅读下面材料，根据其内容和所给段落开头语续写二段，使之构成一篇完整的短文。 When I was in junior high school, my home was only a ten-minute walk from the school. Instead of staying in the dormitory, I went home every noon to have lunch with my mother. These daily lunches were a comforting routine, but little did I know that these lunchtimes would have a profound impact on me. The school year’s highlight was the annual drama competition. To my joy and surprise, I was selected by my teacher to play the lead role of the princess in the play. It was a dream part, and I was determined to excel. Every day after lunch, my mother would help me practice my lines. However, a frustrating problem arose. No matter how perfectly I delivered my lines in the living room, the moment I stepped onto the vast stage, my mind would go blank. The bright lights and silent, expectant audience seemed to swallow my words whole. After several unsuccessful rehearsals, my teacher, with a sympathetic but firm expression, made a difficult decision. She took me aside, explaining that she believed my clear voice was perfectly suited for the crucial role of the narrator, and asked me to consider switching roles. Her words, kindly delivered, still hurt me especially when I saw my part go to another girl. I didn’t tell my mother what had happened when I went home for lunch that day. But she sensed something was wrong. After lunch, instead of practicing lines as usual, she invited me for a walk in the yard. The yard was full of beautiful red roses in full bloom. But among the roses grew many white dandelions (蒲公英). I asked my mother why she didn’t remove the dandelions. She replied that she thought every flower had its own beauty, whether it was a delicate rose or a small dandelion. Her simple, accepting words struck a chord (引起共鸣) deep within me. 注意： 1．续写词数应为150左右； 2．请按如下格式在答题卡的相应位置作答。 I could no longer hold back the flood of sad tears. _______________________________________________________________________________ “You will be an excellent narrator,” Mom said, holding my hands. _______________________________________________________________________________ 试卷第2页，共8页 试卷第1页，共8页 学科网（北京）股份有限公司 答案第2页，共2页 学科网（北京）股份有限公司 $
