Tierna lee is a well known computer scientist who is recognized as being the inventor of the worldwide web. But what inspired him to do so? Well, his parents had a major influence on his career. They were both computer scientists, and they work together on the first computer design for sale, which was called the fanti mark one. As a child, tim discovered a love of electronics when playing with model trains. However, in one thousand hundred and seventy three, he went to works for the university to study physics that did not stop him studying computers in his spare time. In fact, he managed to build his own computer from a broken T. V. set. After he graduated in one thousand seventy six, he worked for a telecoms icons company. Two years later, he worked creating software for printers. IT was in one nine hundred and eighty that he started his project on hypertext. This project created the foundations for establishing the worldwide web. Tierna lee is a well known computer scientist who is recognized as being the inventor of the worldwide web.

Here are the four most common payment choices.Contactless Payments Contactless payments are perfect for drivers in a hurry. With contactless payments, you just tap your phone, and charging starts right away. Operators charge drivers small extra fees, and contactless payments don’t offer discounts.App-Based Payments For home charging users, the apps make it easy to track and manage home charging costs. For operators, app-based systems enable you to collect driver behavior data to improve station performance. New drivers might find the app download and account setup a bit troublesome. The phone signal is necessary for users.Card Payments For older drivers or those who prefer traditional payment methods, card payments are very accessible. For those operators, card readers are easy to set up and maintain and they’re a great alternative if contactless or app systems go wrong. Card payments carry small service fees. Also, card readers need regular care to prevent damage.PnC Payments In a PnC (Plug & Charge) EV charging process, charging starts once you plug in. Plug & Charge payments are linked to a contract (合同) associated with the vehicle and enabled by ISO 15118 using digital certificates. A great EV charger payment system should make charging easier for both drivers and operators. These four payment methods are ready for you to choose from and backed by our round-the-clock after-sales service. 21．Which payment method needs mobile phone signal? A．Contactless Payments. B．Card Payments. C．App-Based Payments. D．PnC Payments. 22．What do Contactless Payments and Card Payments have in common? A．They are suitable for hurried drivers. B．A contract is associated with vehicles. C．Small extra fees are charged to drivers. D．They need regular care against damage. 23．Where is the text probably taken from? A．An online blog. B．An advertisement. C．A science report. D．A fashion magazine. 【答案】21．C 22．C 23．B 【导语】文章介绍了电动汽车充电桩四种主流支付方式，分别说明各类支付方式的优缺点。 【详解】21．细节理解题。根据App-Based Payments部分“The phone signal is necessary for users.(用户必须有手机信号才能使用。)”可知，基于应用程序的支付方式需要手机信号。 22．细节理解题。根据Contactless Payments部分“Operators charge drivers small extra fees, and contactless payments don’t offer discounts.(运营商会向驾驶者收取少量额外手续费，并且非接触式支付不提供折扣优惠。)”以及Card Payments部分“Card payments carry small service fees.(刷卡支付会产生少量服务费。)”可知，两种支付方式的共同点是都会向使用者收取小额费用。 23．推理判断题。根据最后一段“These four payment methods are ready for you to choose from and backed by our round-the-clock after-sales service.(这四种支付方式可供您选择，并且配备我们全天候售后服务。)”可知，文章带有产品推介、宣传的性质，属于广告文体。 B Rosie, a three-year-old black Labrador dog, can do something no person in the world is able to do. She smells four containers of urine (尿液) samples and correctly chooses the one that belongs to a National Health Service patient with bladder (膀胱) cancer. To show it is not just by accident, Rosie’s trainers keep changing the order of the containers. Again and again, the dog finds the cancer sample correctly. Scientists believe this ability could be the beginning of a major change in how we detect cancer. But it has been difficult for researchers to find a way to use this on a large scale in real-world medical settings. It would simply not be practical for the health service to let a group of dogs smell patients in busy hospital waiting rooms. Now, however, technology has offered an answer. Dr Andreas Mershin, a researcher at the Massachusetts Institute of Technology, has worked with the organization Medical Detection Dogs to create an electronic nose, or “e-nose”. This device was developed by training artificial intelligence to copy the way dogs react to the smelly chemicals found in urine. Once the machine learns this, it can also “smell” urine samples by detecting those same tiny chemicals in the air. The e-nose is now being tested on more than 500 urine samples from patients at Milton Keynes University Hospital, to see if it is as accurate as the dogs. Dr Mershin hopes it can be approved as a medical tool in hospitals within two years. He also said the technology could one day even be built into smartphones. The team of scientists and dog trainers works closely with local doctors, who are very hopeful about what the e-nose could achieve. They believe it could lead to tests that do not require any cutting or entering the body. Such tests would be especially important for illnesses where people often delay getting checked because they feel embarrassed, waiting until they experience troubling symptoms. 24．What is the limitation of using dogs for cancer detection? A．They are not accurate enough. B．They are hard to use widely. C．They are too expensive to train. D．They are too difficult to control. 25．What can we infer about the e-nose? A．It may be used in phones. B．It has been applied in treatment. C．It works better than trained dogs. D．It can only detect chemicals in urine. 26．What will be possibly discussed in the following paragraph? A．Further device tests. B．Better ways to train Rosie. C．Causes of bladder cancer. D．Methods of keeping healthy. 27．What can be a suitable title for the text? A．New Ways to Train Working Dogs. B．Dogs with Special Smelling Skills. C．An AI Device for Cancer Detection. D．Traditional Tools for Bladder Cancer. 【答案】24．B 25．A 26．A 27．C 【导语】文章介绍麻省理工学院研究员联合机构研发出电子鼻（e-nose），借助人工智能模仿狗狗识别尿液中特殊化学物质的嗅觉原理，目前该设备正在医院进行样本测试，有望两年内获批成为医疗工具，未来还可能内置到智能手机中。 【详解】24．细节理解题。根据第二段“But it has been difficult for researchers to find a way to use this on a large scale in real-world medical settings(但研究人员一直很难找到一种方法，将这项技术大规模应用于现实医疗场景中。)”可知，用狗狗检测癌症的局限性是难以大规模应用于现实医疗场景。 25．推理判断题。根据第四段“He also said the technology could one day even be built into smartphones.(他还表示，这项技术有朝一日甚至能被内置到智能手机中。)”可知，关于电子鼻我们能推断出未来可能应用在手机上。 26．推理判断题。根据第四段“The e-nose is now being tested on more than 500 urine samples from patients at Milton Keynes University Hospital, to see if it is as accurate as the dogs. Dr Mershin hopes it can be approved as a medical tool in hospitals within two years.(这款电子鼻目前正在米尔顿凯恩斯大学医院，对500多份患者尿液样本进行测试，以此检验它是否能达到和嗅探犬一样的准确率。默欣博士希望它能在两年内获批，成为医院的正规医疗设备。)”可知，文章末尾讲电子鼻正在测试、等待获批医用，按照行文逻辑，下文最可能继续介绍设备的进一步测试与完善。 27．主旨大意题。通读全文，并结合第三段“Dr Andreas Mershin, a researcher at the Massachusetts Institute of Technology, has worked with the organization Medical Detection Dogs to create an electronic nose, or ‘e-nose’.(麻省理工学院的安德烈亚斯・默欣博士与医疗探测犬组织合作，研发出了一款电子鼻。)”可知，文章开篇介绍了拉布拉多犬罗西的癌症检测能力，随后说明用狗来检测癌症的方法难以大规模应用，重点讲述科学家受狗的启发研发出电子鼻，助力癌症无创检测的过程。由此可推知，C项“一款用于癌症检测的人工智能设备”最适合作文章标题。 C “We all know that when there’s an earthquake or a tsunami, the first thing that goes down is the power line. When it’s at night, we’re not going to wait until the next morning to rescue survivors.” said Nitin Sanket, assistant professor of robotics engineering at Worcester Polytechnic Institute. “So we started looking at nature. Is there a creature in the world which can actually do this?” Sanket and his students found their answer in bats and the winged mammal’s remarkable ability to echolocate, or find their way via reflected sound. They’re developing air robots that can be flown where and when current drones can’t operate. Sanket’s drone fits in the palm of his hand, and is made mostly from inexpensive hobby-grade materials and can operate in the dark. A small ultrasonic (超声的) sensor, not unlike those used in automatic faucets (龙头) in public restrooms, copies bat behavior, sending out a pulse (脉冲) of high-frequency sound and using the echo to detect obstacles in its path. During a recent demonstration, a student used a remote control to launch the drone in a brightly lit room and then again after turning off all but a faintly glowing red light. As it approached a transparent glass wall, the drone repeatedly stopped and backed away, even with the lights off and with fog and fake snow floating in the air. Yet, the research didn’t always get along well. The researchers realized that the noise of the bat robot disturbed the ultrasound, requiring 3D-printed shells to minimize the disturbance. They also used AI to teach the drone how to filter (过滤) and interpret sound signals. Still, there’s a long way to go to match bats, which can contract their ear muscles to listen only to certain echoes and can detect something as small as a human hair from several meters away. Sanket said, “We are nowhere close to what nature has achieved, but someday we will be there and these will be useful for application in the wild.” 28．Why did Sanket’s team study bats? A．For their physical strength. B．For their high flight speed. C．For their easy accessibility. D．For their navigation skills. 29．What can we learn about the drone from the demonstration? A．It could even break through glass walls. B．It performed well regardless of visibility. C．It required adjustment to avoid obstacles, D．It needed human help to detect obstacles, 30．What challenge did the researchers encounter during the research? A．The materials were hardly accessible, B．The sensor generated too much noise. C．The AI system failed to process the sound signals. D．The drone’s operational noise affected its sensor. 31．What does Sanket think of their present achievement? A．It needs further development. B．It’s unrealistic for practical use. C．It is ready for widespread use. D．It has already outperformed bats. 【答案】28．D 29．B 30．D 31．A 【导语】文章主要讲述了桑凯特团队受蝙蝠启发研发可在黑暗中飞行的无人机及面临的挑战。 【详解】28．细节理解题。根据第三段“Sanket’s drone fits in the palm of his hand, and is made mostly from inexpensive hobby-grade materials and can operate in the dark. A small ultrasonic (超声的) sensor, not unlike those used in automatic faucets (龙头) in public restrooms, copies bat behavior, sending out a pulse (脉冲) of high-frequency sound and using the echo to detect obstacles in its path.(桑凯特的无人机可以放在他的手掌中，主要由便宜的业余级材料制成，可以在黑暗中运行。一个小型超声波传感器，与公共卫生间自动水龙头中使用的传感器类似，模仿蝙蝠的行为，发出高频声脉冲，并利用回声探测路径中的障碍物。)”可知，桑凯特的团队研究蝙蝠是为了它们的导航技能。 29．细节理解题。根据第四段“During a recent demonstration, a student used a remote control to launch the drone in a brightly lit room and then again after turning off all but a faintly glowing red light. As it approached a transparent glass wall, the drone repeatedly stopped and backed away, even with the lights off and with fog and fake snow floating in the air.(在最近的一次演示中，一名学生用遥控器在一个光线明亮的房间里发射无人机，然后在关掉所有灯，只留一盏微弱的红灯后再次发射。当它接近一堵透明的玻璃墙时，无人机反复停下并后退，即使是在灯光熄灭、空气中弥漫着雾气和假雪的情况下。)”可知，从演示中我们可以了解到无人机无论能见度如何都表现良好。 30．细节理解题。根据第五段中“Yet, the research didn’t always get along well. The researchers realized that the noise of the bat robot disturbed the ultrasound, requiring 3D-printed shells to minimize the disturbance.(然而，研究并不总是一帆风顺。研究人员意识到，蝙蝠机器人的噪音干扰了超声波，需要3D打印外壳来尽量减少干扰。)”可知，研究人员在研究过程中遇到的挑战是无人机的操作噪音影响了它的传感器。 31．推理判断题。根据最后一段“Still, there’s a long way to go to match bats, which can contract their ear muscles to listen only to certain echoes and can detect something as small as a human hair from several meters away. Sanket said, “We are nowhere close to what nature has achieved, but someday we will be there and these will be useful for application in the wild.”(尽管如此，要赶上蝙蝠还有很长的路要走，蝙蝠可以收缩耳部肌肉，只听特定的回声，并且可以从几米外探测到像人类头发一样小的东西。桑凯特说：“我们离大自然所取得的成就还差得很远，但总有一天我们会达到那个水平，这些将对野外应用有用。”)”可知，桑凯特认为他们目前的成就需要进一步发展。 D You, along with all living things, produce weak light that glows (发出微弱稳定的光) until you die, according to a recent study. It’s called ultraweak photon emission (UPE) and is a natural product of your metabolism (新陈代谢). UPE is produced when chemicals in your cells create unstable molecules (分子) known as reactive oxygen species (ROS) as by-products of your body’s metabolism. When ROS levels rise, they cause other molecules to become “excited”, meaning they carry excess (额外的) energy. It’s this energy that causes light to be released. “I normally point out that UPE is a result of a biochemical process and in that sense is related to what happens in a glow-stick,” Dr Daniel Oblak, a physicist at the University of Calgary and last author of the study, said. “UPE is so weak that it is not visible to the human eye and completely overwhelmed by other sources of light, unless you are in a completely dark room.” That’s not to say that shutting your curtains and turning off your lights will allow you to see your own glow. This light is between 1,000 and 1,000,000 times weaker than the human eye can perceive. Using specialist cameras, scientists observed much more UPE being released by the living mice, compared to their dead bodies. Meanwhile, the leaves gave off much more light where they had been damaged, compared to undamaged areas. That’s because they were experiencing more oxidative (氧化的) stress in damaged regions. But the dead mice did not glow, because their bodies weren’t metabolising anymore. Oblak said that the key advantage of UPE is that it offers a non-invasive method of observing the health of living things. “This could be used to track the condition of a tissue — for example, for use in transplants — or the level of stress an organism is subject to, such as for monitoring crop or forest health,” he said. But this field is still full of unknowns. For instance, Oblak said, “Perhaps UPE is not just a byproduct of metabolic processes, but also serves a purpose.” Scientists just aren’t sure yet. 32．What causes ultraweak photon emission? A．The presence of reactive oxygen species in cells. B．Direct exposure to bright light in a dark room. C．The use of specialized cameras on dead organisms. D．The human eye’s ability to perceive dim light. 33．What can be learned about UPE from the text? A．It is visible to the human eye without equipment. B．It is a supernatural phenomenon. C．It is generated through a biochemical process. D．It is only produced by damaged tissues. 34．Why did the injured leaves give off more light than undamaged areas? A．They were suffering more oxidative stress. B．They were no longer metabolizing. C．They produced more reactive oxygen species after death. D．They were placed in a completely dark room. 35．What is the author’s purpose in writing the text? A．To explain why dead organisms stop glowing. B．To compare UPE in mice and plants. C．To argue that UPE is a purposeful biological signal. D．To introduce UPE and its potential applications. 【答案】32．A 33．C 34．A 35．D 【导语】这篇文章主要介绍了超微弱光子发射（UPE）这一自然现象：它是生物新陈代谢产生的生化副产物，强度极弱无法被人眼直接观察；受损组织因氧化应激更强会释放更多UPE，而死亡生物因停止代谢不再发光。UPE可作为非侵入式手段用于生物健康监测，但其是否具有特定生物功能仍有待研究。 【详解】32．细节理解题。根据第一段中“UPE is produced when chemicals in your cells create unstable molecules (分子) known as reactive oxygen species (ROS) as by-products of your body’s metabolism. When ROS levels rise, they cause other molecules to become “excited”, meaning they carry excess (额外的) energy. It’s this energy that causes light to be released.( 当您细胞内的化学物质产生不稳定分子（即活性氧物质，简称 ROS）作为身体新陈代谢的副产品时，就会产生 UPE。当 ROS 水平升高时，它们会使其他分子“兴奋”，即它们携带过多的能量。正是这种能量导致光被释放出来。)”可知，细胞内存在活性氧物质导致了超弱光子的发射。 33．细节理解题。根据第二段““I normally point out that UPE is a result of a biochemical process and in that sense is related to what happens in a glow-stick,” Dr Daniel Oblak, a physicist at the University of Calgary and last author of the study, said.( “我通常会指出，UPE 是一种生物化学过程的结果，从这个意义上说，它与发光棒所发生的情况有关，”卡尔加里大学的物理学家丹尼尔·奥布拉克博士（该研究的最后作者）说道。)”可知，UPE 是通过生化过程产生的。 34．细节理解题。根据第五段“That’s because they were experiencing more oxidative (氧化的) stress in damaged regions. But the dead mice did not glow, because their bodies weren’t metabolising anymore.( 这是因为受损区域的生物体承受着更多的氧化应激。但死鼠不会发光，因为它们的体内不再进行新陈代谢。)”可知，受损的叶子比未受损的区域能发出更多的光是因为受损区域遭受了更多氧化应激。 35．推理判断题。根据文章大意以及最后一段“But this field is still full of unknowns. For instance, Oblak said, “Perhaps UPE is not just a byproduct of metabolic processes, but also serves a purpose.” Scientists just aren’t sure yet.( 但这一领域仍充满未知。例如，奥布拉克说：“也许UPE不仅仅是代谢过程的副产品，还具有某种作用。”科学家们目前还不确定这一点。)”可知，全文结构清晰：前四段介绍UPE的定义、产生机制和基本特性；第五段解释实验现象的原因；第六、七段重点介绍UPE在组织移植监测、作物和森林健康监测等方面的潜在应用；最后一段指出该领域仍存在未知。整体目的是全面介绍UPE及其应用前景。 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。 Did you know that your stylish jacket or favorite jeans might once have been plastic bottles? This is the world of rPET, also known as recycled polyester (再生聚酯纤维). 36 As a result, a used water bottle can take on a new life as activewear or even high-fashion pieces. 37 First, plastic bottles are collected, sorted, and cleaned. After cleaning, they are cut, melted into liquid, and stretched into thin fibers. These fibers are then spun into yarn (纱线), which can be woven into different kinds of fabric. Finally, the fabric goes through finishing processes such as printing or coating to achieve the desired color, pattern, and performance. Some people assume that clothing made from “waste” must be cheap or low-quality. It is true that plastic-based fabrics can be less breathable and may feel rough for people with sensitive skin. 38 According to a Textile (纺织品) Exchange report, the use of rPET grew by 20% between 2020 and 2021, and made up about 14% of all global polyester production in 2022. This growth comes from rising awareness of both its practical advantages and its environmental value. In terms of performance, rPET is strong, durable, and quick-drying — qualities that make it ideal for sportswear. 39 Beyond performance, rPET supports the environment. Producing it uses 99% less water than producing traditional polyester, an important benefit for water-stressed regions involved in textile manufacturing. It also helps reduce waste. About 25 rPET bottles can be turned into the fibers for one jacket. 40 rPET is not a perfect solution to plastic pollution, but it is a meaningful step toward more sustainable fashion and a cleaner planet. A．It is also lightweight and wrinkle-resistant. B．However, market trends tell a different story. C．The transformation happens through several steps. D．This keeps millions of plastic bottles out of landfills each year. E．Recycling rPET fabric back into new fabric can be challenging. F．While it is safe to wear, it releases microplastics when it is washed. G．Unlike traditional polyester made from petrol, rPET uses existing plastic. 【答案】36．G 37．C 38．B 39．A 40．D 【导语】本文主要介绍再生聚酯纤维rPET，讲解其原料来源、制作流程、市场发展、性能优势与环保价值，指出它虽不完美，但助力可持续时尚发展。 【详解】36．根据上文“Did you know that your stylish jacket or favorite jeans might once have been plastic bottles? This is the world of rPET, also known as recycled polyester (再生聚酯纤维).(你知道吗，你时尚的夹克或最喜欢的牛仔裤可能曾经是塑料瓶？这就是rPET的世界，也被称为再生聚酯纤维。)”以及下文“As a result, a used water bottle can take on a new life as activewear or even high - fashion pieces.(因此，一个用过的水瓶可以以运动服甚至高级时装的形式获得新生。)”可知，空格处需介绍rPET 的原料特点。G选项“Unlike traditional polyester made from petrol, rPET uses existing plastic.(与由石油制成的传统聚酯纤维不同，rPET使用现有的塑料。)”符合语境，承接上文对rPET的介绍，引出下文用过的水瓶能获得新生的内容。 37．根据下文“First, plastic bottles are collected, sorted, and cleaned. After cleaning, they are cut, melted into liquid, and stretched into thin fibers. These fibers are then spun into yarn (纱线), which can be woven into different kinds of fabric. Finally, the fabric goes through finishing processes such as printing or coating to achieve the desired color, pattern, and performance.(首先，收集、分类和清洁塑料瓶。清洁后，将它们切割、熔化成液体，并拉伸成细纤维。然后，这些纤维被纺成纱线，可以编织成不同种类的织物。最后，织物经过印刷或涂层等整理工序，以达到所需的颜色、图案和性能。)”可知，此段主要介绍了塑料瓶变成rPET面料的过程，即通过几个步骤实现转变。C选项“The transformation happens through several steps.(这种转变通过几个步骤发生。)”符合语境，引出下文对具体步骤的介绍。 38．根据上文“Some people assume that clothing made from “waste” must be cheap or low-quality. It is true that plastic-based fabrics can be less breathable and may feel rough for people with sensitive skin.(有些人认为用“废物”制成的衣服一定很便宜或质量低劣。的确，基于塑料的面料透气性可能较差，对敏感皮肤的人来说可能会感觉粗糙。)”以及下文“According to a Textile (纺织品) Exchange report, the use of rPET grew by 20% between 2020 and 2021, and made up about 14% of all global polyester production in 2022.(根据纺织品交易所的一份报告，2020年至2021年间，rPET的使用量增长了20%，2022年占全球聚酯纤维总产量的约14%。)”可知，上文提到有些人对rPET制成的衣服有负面看法，下文却表明rPET的使用量在增长，前后内容存在转折关系。B选项“However, market trends tell a different story.(然而，市场趋势却讲述了另一个故事。)”转折过渡，说明市场情况与人们想法不同。 39．根据上文“In terms of performance, rPET is strong, durable, and quick-drying — qualities that make it ideal for sportswear.(在性能方面，rPET坚固、耐用且速干，这些特性使其成为运动服装的理想选择。)”可知，此段在介绍rPET的性能优势，此处应继续说明其其他性能优势。A选项“It is also lightweight and wrinkle - resistant.(它还重量轻且抗皱。)”用并列结构补充其性能优势，与上文内容衔接紧密。 40．根据上文“Beyond performance, rPET supports the environment. Producing it uses 99% less water than producing traditional polyester, an important benefit for water-stressed regions involved in textile manufacturing. It also helps reduce waste. About 25 rPET bottles can be turned into the fibers for one jacket.(除了性能之外，rPET还有利于环境。与传统聚酯纤维的生产相比，它的生产用水量减少了99%，这对参与纺织制造的水资源紧张地区来说是一个重要好处。它还有助于减少浪费。大约25个rPET瓶子可以制成一件夹克的纤维。)”可知，此段在介绍rPET的环保价值，空格处需说明该做法的环保成效。D选项“This keeps millions of plastic bottles out of landfills each year.(这每年使数百万个塑料瓶远离垃圾填埋场。)”承接上文减少浪费的内容，具体体现 rPET的环保价值，符合语境。 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。 Beckett Zahedi and Derrick Webster Jr. have created a website called Realer Estate.

It was May, yet we walked up a snow-covered hill. When we noticed our jeans were wet up to our knees, it did not dampen our spirits Not once did we say, “Let’s turn around.” This was our vacation, and we were on an adventure. Little did we know this was the beginning of many more surprises. The trail was marked as an easy one-kilometer like yet we were already walking a long distance. Our light-heartedness stopped when we came out into a clearing and saw a parking lot without our rental car in it. As my eyes scanned the surroundings, nothing looked familiar. My heart raced. I realized we were lost in a national park that did not officially open for another week. Usually, I am the calm one in the relationship, but my husband surprised me with his calmness. This did not comfort me; in fact, it heightened my fear. As we walked, I asked my husband to call for help, but there was no cell-phone signal in this isolated（偏僻的）area. It was awfully quiet except for our footsteps hitting the road, and my heavy breathing. My husband suggested we conserve energy and walk slower. With each step on the road, my feet and thighs hurt while my mind raced with thoughts about people who got lost in the Canadian woods for days. My vision sharpened. I noticed everything around me: the trees, rocks and snow. I thought we could eat the snow on the ground in case we needed water. For the first time in my life, I was ready and willing to get a ride, but we did not meet with a single car on the road. Silently, I prayed multiple times. We focused on each other, made joint decisions and connected through gratitude. We managed to stay on the main road and walked straight on.

In no time we found ourselves heading for it. We were filled with hope and excitement to find such a building in the middle of nowhere. We climbed up the hill at a swinging pace as if all the pains were gone. As we approached, a sign came into sight, which read: Administration Office. However, it was not open for business. The empty hall made us nervous all at once. We stood there hopelessly, wondering what to do next. Paragraph 2： Just then, a friendly woman appeared, saying, “Hello.” I could barely hold back my enthusiasm and blurted out, “Were lost!” She comforted us and opened a room for us to take a break. Seeing we were cold and hungry, she treated us with hot chocolate. After studying the map, we figured out that our car was parked over three kilometers away. She offered us a ride back to our car and we accepted gladly. I felt relieved to see our rental car again.

Here are the four most common payment choices.Contactless Payments Contactless payments are perfect for drivers in a hurry. With contactless payments, you just tap your phone, and charging starts right away. Operators charge drivers small extra fees, and contactless payments don’t offer discounts.App-Based Payments For home charging users, the apps make it easy to track and manage home charging costs. For operators, app-based systems enable you to collect driver behavior data to improve station performance. New drivers might find the app download and account setup a bit troublesome. The phone signal is necessary for users.Card Payments For older drivers or those who prefer traditional payment methods, card payments are very accessible. For those operators, card readers are easy to set up and maintain and they’re a great alternative if contactless or app systems go wrong. Card payments carry small service fees. Also, card readers need regular care to prevent damage.PnC Payments In a PnC (Plug & Charge) EV charging process, charging starts once you plug in. Plug & Charge payments are linked to a contract (合同) associated with the vehicle and enabled by ISO 15118 using digital certificates. A great EV charger payment system should make charging easier for both drivers and operators. These four payment methods are ready for you to choose from and backed by our round-the-clock after-sales service. 21．Which payment method needs mobile phone signal? A．Contactless Payments. B．Card Payments. C．App-Based Payments. D．PnC Payments. 22．What do Contactless Payments and Card Payments have in common? A．They are suitable for hurried drivers. B．A contract is associated with vehicles. C．Small extra fees are charged to drivers. D．They need regular care against damage. 23．Where is the text probably taken from? A．An online blog. B．An advertisement. C．A science report. D．A fashion magazine. B Rosie, a three-year-old black Labrador dog, can do something no person in the world is able to do. She smells four containers of urine (尿液) samples and correctly chooses the one that belongs to a National Health Service patient with bladder (膀胱) cancer. To show it is not just by accident, Rosie’s trainers keep changing the order of the containers. Again and again, the dog finds the cancer sample correctly. Scientists believe this ability could be the beginning of a major change in how we detect cancer. But it has been difficult for researchers to find a way to use this on a large scale in real-world medical settings. It would simply not be practical for the health service to let a group of dogs smell patients in busy hospital waiting rooms. Now, however, technology has offered an answer. Dr Andreas Mershin, a researcher at the Massachusetts Institute of Technology, has worked with the organization Medical Detection Dogs to create an electronic nose, or “e-nose”. This device was developed by training artificial intelligence to copy the way dogs react to the smelly chemicals found in urine. Once the machine learns this, it can also “smell” urine samples by detecting those same tiny chemicals in the air. The e-nose is now being tested on more than 500 urine samples from patients at Milton Keynes University Hospital, to see if it is as accurate as the dogs. Dr Mershin hopes it can be approved as a medical tool in hospitals within two years. He also said the technology could one day even be built into smartphones. The team of scientists and dog trainers works closely with local doctors, who are very hopeful about what the e-nose could achieve. They believe it could lead to tests that do not require any cutting or entering the body. Such tests would be especially important for illnesses where people often delay getting checked because they feel embarrassed, waiting until they experience troubling symptoms. 24．What is the limitation of using dogs for cancer detection? A．They are not accurate enough. B．They are hard to use widely. C．They are too expensive to train. D．They are too difficult to control. 25．What can we infer about the e-nose? A．It may be used in phones. B．It has been applied in treatment. C．It works better than trained dogs. D．It can only detect chemicals in urine. 26．What will be possibly discussed in the following paragraph? A．Further device tests. B．Better ways to train Rosie. C．Causes of bladder cancer. D．Methods of keeping healthy. 27．What can be a suitable title for the text? A．New Ways to Train Working Dogs. B．Dogs with Special Smelling Skills. C．An AI Device for Cancer Detection. D．Traditional Tools for Bladder Cancer. C “We all know that when there’s an earthquake or a tsunami, the first thing that goes down is the power line. When it’s at night, we’re not going to wait until the next morning to rescue survivors.” said Nitin Sanket, assistant professor of robotics engineering at Worcester Polytechnic Institute. “So we started looking at nature. Is there a creature in the world which can actually do this?” Sanket and his students found their answer in bats and the winged mammal’s remarkable ability to echolocate, or find their way via reflected sound. They’re developing air robots that can be flown where and when current drones can’t operate. Sanket’s drone fits in the palm of his hand, and is made mostly from inexpensive hobby-grade materials and can operate in the dark. A small ultrasonic (超声的) sensor, not unlike those used in automatic faucets (龙头) in public restrooms, copies bat behavior, sending out a pulse (脉冲) of high-frequency sound and using the echo to detect obstacles in its path. During a recent demonstration, a student used a remote control to launch the drone in a brightly lit room and then again after turning off all but a faintly glowing red light. As it approached a transparent glass wall, the drone repeatedly stopped and backed away, even with the lights off and with fog and fake snow floating in the air. Yet, the research didn’t always get along well. The researchers realized that the noise of the bat robot disturbed the ultrasound, requiring 3D-printed shells to minimize the disturbance. They also used AI to teach the drone how to filter (过滤) and interpret sound signals. Still, there’s a long way to go to match bats, which can contract their ear muscles to listen only to certain echoes and can detect something as small as a human hair from several meters away. Sanket said, “We are nowhere close to what nature has achieved, but someday we will be there and these will be useful for application in the wild.” 28．Why did Sanket’s team study bats? A．For their physical strength. B．For their high flight speed. C．For their easy accessibility. D．For their navigation skills. 29．What can we learn about the drone from the demonstration? A．It could even break through glass walls. B．It performed well regardless of visibility. C．It required adjustment to avoid obstacles, D．It needed human help to detect obstacles, 30．What challenge did the researchers encounter during the research? A．The materials were hardly accessible, B．The sensor generated too much noise. C．The AI system failed to process the sound signals. D．The drone’s operational noise affected its sensor. 31．What does Sanket think of their present achievement? A．It needs further development. B．It’s unrealistic for practical use. C．It is ready for widespread use. D．It has already outperformed bats. D You, along with all living things, produce weak light that glows (发出微弱稳定的光) until you die, according to a recent study. It’s called ultraweak photon emission (UPE) and is a natural product of your metabolism (新陈代谢). UPE is produced when chemicals in your cells create unstable molecules (分子) known as reactive oxygen species (ROS) as by-products of your body’s metabolism. When ROS levels rise, they cause other molecules to become “excited”, meaning they carry excess (额外的) energy. It’s this energy that causes light to be released. “I normally point out that UPE is a result of a biochemical process and in that sense is related to what happens in a glow-stick,” Dr Daniel Oblak, a physicist at the University of Calgary and last author of the study, said. “UPE is so weak that it is not visible to the human eye and completely overwhelmed by other sources of light, unless you are in a completely dark room.” That’s not to say that shutting your curtains and turning off your lights will allow you to see your own glow. This light is between 1,000 and 1,000,000 times weaker than the human eye can perceive. Using specialist cameras, scientists observed much more UPE being released by the living mice, compared to their dead bodies. Meanwhile, the leaves gave off much more light where they had been damaged, compared to undamaged areas. That’s because they were experiencing more oxidative (氧化的) stress in damaged regions. But the dead mice did not glow, because their bodies weren’t metabolising anymore. Oblak said that the key advantage of UPE is that it offers a non-invasive method of observing the health of living things. “This could be used to track the condition of a tissue — for example, for use in transplants — or the level of stress an organism is subject to, such as for monitoring crop or forest health,” he said. But this field is still full of unknowns. For instance, Oblak said, “Perhaps UPE is not just a byproduct of metabolic processes, but also serves a purpose.” Scientists just aren’t sure yet. 32．What causes ultraweak photon emission? A．The presence of reactive oxygen species in cells. B．Direct exposure to bright light in a dark room. C．The use of specialized cameras on dead organisms. D．The human eye’s ability to perceive dim light. 33．What can be learned about UPE from the text? A．It is visible to the human eye without equipment. B．It is a supernatural phenomenon. C．It is generated through a biochemical process. D．It is only produced by damaged tissues. 34．Why did the injured leaves give off more light than undamaged areas? A．They were suffering more oxidative stress. B．They were no longer metabolizing. C．They produced more reactive oxygen species after death. D．They were placed in a completely dark room. 35．What is the author’s purpose in writing the text? A．To explain why dead organisms stop glowing. B．To compare UPE in mice and plants. C．To argue that UPE is a purposeful biological signal. D．To introduce UPE and its potential applications. 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。 Think Like a Farmer Did you know that your stylish jacket or favorite jeans might once have been plastic bottles? This is the world of rPET, also known as recycled polyester (再生聚酯纤维). 36 As a result, a used water bottle can take on a new life as activewear or even high-fashion pieces. 37 First, plastic bottles are collected, sorted, and cleaned. After cleaning, they are cut, melted into liquid, and stretched into thin fibers. These fibers are then spun into yarn (纱线), which can be woven into different kinds of fabric. Finally, the fabric goes through finishing processes such as printing or coating to achieve the desired color, pattern, and performance. Some people assume that clothing made from “waste” must be cheap or low-quality. It is true that plastic-based fabrics can be less breathable and may feel rough for people with sensitive skin. 38 According to a Textile (纺织品) Exchange report, the use of rPET grew by 20% between 2020 and 2021, and made up about 14% of all global polyester production in 2022. This growth comes from rising awareness of both its practical advantages and its environmental value. In terms of performance, rPET is strong, durable, and quick-drying — qualities that make it ideal for sportswear. 39 Beyond performance, rPET supports the environment. Producing it uses 99% less water than producing traditional polyester, an important benefit for water-stressed regions involved in textile manufacturing. It also helps reduce waste. About 25 rPET bottles can be turned into the fibers for one jacket. 40 rPET is not a perfect solution to plastic pollution, but it is a meaningful step toward more sustainable fashion and a cleaner planet. A．It is also lightweight and wrinkle-resistant. B．However, market trends tell a different story. C．The transformation happens through several steps. D．This keeps millions of plastic bottles out of landfills each year. E．Recycling rPET fabric back into new fabric can be challenging. F．While it is safe to wear, it releases microplastics when it is washed. G．Unlike traditional polyester made from petrol, rPET uses existing plastic. 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。 Beckett Zahedi and Derrick Webster Jr. have created a website called Realer Estate. It is a platform 41 to help renters more easily find proper and rent-stabilized apartments in a city where affordable housing costs are often out of 42 .

It was May, yet we walked up a snow-covered hill. When we noticed our jeans were wet up to our knees, it did not dampen our spirits Not once did we say, “Let’s turn around.” This was our vacation, and we were on an adventure. Little did we know this was the beginning of many more surprises. The trail was marked as an easy one-kilometer like yet we were already walking a long distance.

Among the many devices and apps I use daily, the smartwatch stands out as the most practical. It helps me communicate better by informing me of messages and allowing voice calls without taking out my phone. For learning, it tracks study time and sets reminders for tasks, making it convenient and time-saving. With it, I can manage both schoolwork and personal life more efficiently. This small device shows how technology turns challenges into ease and adds value to our daily routines. 第二节 （满分25分） Paragraph 1 My husband suddenly spotted a small building on a hill in the distance. In no time we found ourselves heading for it. We were filled with hope and excitement to find such a building in the middle of nowhere. We climbed up the hill at a swinging pace as if all the pains were gone. As we approached, a sign came into sight, which read: Administration Office. However, it was not open for business. The empty hall made us nervous all at once. We stood there hopelessly, wondering what to do next. Paragraph 2： Just then, a friendly woman appeared, saying, “Hello.” I could barely hold back my enthusiasm and blurted out, “Were lost!” She comforted us and opened a room for us to take a break. Seeing we were cold and hungry, she treated us with hot chocolate. After studying the map, we figured out that our car was parked over three kilometers away. She offered us a ride back to our car and we accepted gladly. I felt relieved to see our rental car again.

Here are the four most common payment choices.Contactless Payments Contactless payments are perfect for drivers in a hurry. With contactless payments, you just tap your phone, and charging starts right away. Operators charge drivers small extra fees, and contactless payments don’t offer discounts.App-Based Payments For home charging users, the apps make it easy to track and manage home charging costs. For operators, app-based systems enable you to collect driver behavior data to improve station performance. New drivers might find the app download and account setup a bit troublesome. The phone signal is necessary for users.Card Payments For older drivers or those who prefer traditional payment methods, card payments are very accessible. For those operators, card readers are easy to set up and maintain and they’re a great alternative if contactless or app systems go wrong. Card payments carry small service fees. Also, card readers need regular care to prevent damage.PnC Payments In a PnC (Plug & Charge) EV charging process, charging starts once you plug in. Plug & Charge payments are linked to a contract (合同) associated with the vehicle and enabled by ISO 15118 using digital certificates. A great EV charger payment system should make charging easier for both drivers and operators. These four payment methods are ready for you to choose from and backed by our round-the-clock after-sales service. 21．Which payment method needs mobile phone signal? A．Contactless Payments. B．Card Payments. C．App-Based Payments. D．PnC Payments. 22．What do Contactless Payments and Card Payments have in common? A．They are suitable for hurried drivers. B．A contract is associated with vehicles. C．Small extra fees are charged to drivers. D．They need regular care against damage. 23．Where is the text probably taken from? A．An online blog. B．An advertisement. C．A science report. D．A fashion magazine. B Rosie, a three-year-old black Labrador dog, can do something no person in the world is able to do. She smells four containers of urine (尿液) samples and correctly chooses the one that belongs to a National Health Service patient with bladder (膀胱) cancer. To show it is not just by accident, Rosie’s trainers keep changing the order of the containers. Again and again, the dog finds the cancer sample correctly. Scientists believe this ability could be the beginning of a major change in how we detect cancer. But it has been difficult for researchers to find a way to use this on a large scale in real-world medical settings. It would simply not be practical for the health service to let a group of dogs smell patients in busy hospital waiting rooms. Now, however, technology has offered an answer. Dr Andreas Mershin, a researcher at the Massachusetts Institute of Technology, has worked with the organization Medical Detection Dogs to create an electronic nose, or “e-nose”. This device was developed by training artificial intelligence to copy the way dogs react to the smelly chemicals found in urine. Once the machine learns this, it can also “smell” urine samples by detecting those same tiny chemicals in the air. The e-nose is now being tested on more than 500 urine samples from patients at Milton Keynes University Hospital, to see if it is as accurate as the dogs. Dr Mershin hopes it can be approved as a medical tool in hospitals within two years. He also said the technology could one day even be built into smartphones. The team of scientists and dog trainers works closely with local doctors, who are very hopeful about what the e-nose could achieve. They believe it could lead to tests that do not require any cutting or entering the body. Such tests would be especially important for illnesses where people often delay getting checked because they feel embarrassed, waiting until they experience troubling symptoms. 24．What is the limitation of using dogs for cancer detection? A．They are not accurate enough. B．They are hard to use widely. C．They are too expensive to train. D．They are too difficult to control. 25．What can we infer about the e-nose? A．It may be used in phones. B．It has been applied in treatment. C．It works better than trained dogs. D．It can only detect chemicals in urine. 26．What will be possibly discussed in the following paragraph? A．Further device tests. B．Better ways to train Rosie. C．Causes of bladder cancer. D．Methods of keeping healthy. 27．What can be a suitable title for the text? A．New Ways to Train Working Dogs. B．Dogs with Special Smelling Skills. C．An AI Device for Cancer Detection. D．Traditional Tools for Bladder Cancer. C “We all know that when there’s an earthquake or a tsunami, the first thing that goes down is the power line. When it’s at night, we’re not going to wait until the next morning to rescue survivors.” said Nitin Sanket, assistant professor of robotics engineering at Worcester Polytechnic Institute. “So we started looking at nature. Is there a creature in the world which can actually do this?” Sanket and his students found their answer in bats and the winged mammal’s remarkable ability to echolocate, or find their way via reflected sound. They’re developing air robots that can be flown where and when current drones can’t operate. Sanket’s drone fits in the palm of his hand, and is made mostly from inexpensive hobby-grade materials and can operate in the dark. A small ultrasonic (超声的) sensor, not unlike those used in automatic faucets (龙头) in public restrooms, copies bat behavior, sending out a pulse (脉冲) of high-frequency sound and using the echo to detect obstacles in its path. During a recent demonstration, a student used a remote control to launch the drone in a brightly lit room and then again after turning off all but a faintly glowing red light. As it approached a transparent glass wall, the drone repeatedly stopped and backed away, even with the lights off and with fog and fake snow floating in the air. Yet, the research didn’t always get along well. The researchers realized that the noise of the bat robot disturbed the ultrasound, requiring 3D-printed shells to minimize the disturbance. They also used AI to teach the drone how to filter (过滤) and interpret sound signals. Still, there’s a long way to go to match bats, which can contract their ear muscles to listen only to certain echoes and can detect something as small as a human hair from several meters away. Sanket said, “We are nowhere close to what nature has achieved, but someday we will be there and these will be useful for application in the wild.” 28．Why did Sanket’s team study bats? A．For their physical strength. B．For their high flight speed. C．For their easy accessibility. D．For their navigation skills. 29．What can we learn about the drone from the demonstration? A．It could even break through glass walls. B．It performed well regardless of visibility. C．It required adjustment to avoid obstacles, D．It needed human help to detect obstacles, 30．What challenge did the researchers encounter during the research? A．The materials were hardly accessible, B．The sensor generated too much noise. C．The AI system failed to process the sound signals. D．The drone’s operational noise affected its sensor. 31．What does Sanket think of their present achievement? A．It needs further development. B．It’s unrealistic for practical use. C．It is ready for widespread use. D．It has already outperformed bats. D You, along with all living things, produce weak light that glows (发出微弱稳定的光) until you die, according to a recent study. It’s called ultraweak photon emission (UPE) and is a natural product of your metabolism (新陈代谢). UPE is produced when chemicals in your cells create unstable molecules (分子) known as reactive oxygen species (ROS) as by-products of your body’s metabolism. When ROS levels rise, they cause other molecules to become “excited”, meaning they carry excess (额外的) energy. It’s this energy that causes light to be released. “I normally point out that UPE is a result of a biochemical process and in that sense is related to what happens in a glow-stick,” Dr Daniel Oblak, a physicist at the University of Calgary and last author of the study, said. “UPE is so weak that it is not visible to the human eye and completely overwhelmed by other sources of light, unless you are in a completely dark room.” That’s not to say that shutting your curtains and turning off your lights will allow you to see your own glow. This light is between 1,000 and 1,000,000 times weaker than the human eye can perceive. Using specialist cameras, scientists observed much more UPE being released by the living mice, compared to their dead bodies. Meanwhile, the leaves gave off much more light where they had been damaged, compared to undamaged areas. That’s because they were experiencing more oxidative (氧化的) stress in damaged regions. But the dead mice did not glow, because their bodies weren’t metabolising anymore. Oblak said that the key advantage of UPE is that it offers a non-invasive method of observing the health of living things. “This could be used to track the condition of a tissue — for example, for use in transplants — or the level of stress an organism is subject to, such as for monitoring crop or forest health,” he said. But this field is still full of unknowns. For instance, Oblak said, “Perhaps UPE is not just a byproduct of metabolic processes, but also serves a purpose.” Scientists just aren’t sure yet. 32．What causes ultraweak photon emission? A．The presence of reactive oxygen species in cells. B．Direct exposure to bright light in a dark room. C．The use of specialized cameras on dead organisms. D．The human eye’s ability to perceive dim light. 33．What can be learned about UPE from the text? A．It is visible to the human eye without equipment. B．It is a supernatural phenomenon. C．It is generated through a biochemical process. D．It is only produced by damaged tissues. 34．Why did the injured leaves give off more light than undamaged areas? A．They were suffering more oxidative stress. B．They were no longer metabolizing. C．They produced more reactive oxygen species after death. D．They were placed in a completely dark room. 35．What is the author’s purpose in writing the text? A．To explain why dead organisms stop glowing. B．To compare UPE in mice and plants. C．To argue that UPE is a purposeful biological signal. D．To introduce UPE and its potential applications. 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。 Did you know that your stylish jacket or favorite jeans might once have been plastic bottles? This is the world of rPET, also known as recycled polyester (再生聚酯纤维). 36 As a result, a used water bottle can take on a new life as activewear or even high-fashion pieces. 37 First, plastic bottles are collected, sorted, and cleaned. After cleaning, they are cut, melted into liquid, and stretched into thin fibers. These fibers are then spun into yarn (纱线), which can be woven into different kinds of fabric. Finally, the fabric goes through finishing processes such as printing or coating to achieve the desired color, pattern, and performance. Some people assume that clothing made from “waste” must be cheap or low-quality. It is true that plastic-based fabrics can be less breathable and may feel rough for people with sensitive skin. 38 According to a Textile (纺织品) Exchange report, the use of rPET grew by 20% between 2020 and 2021, and made up about 14% of all global polyester production in 2022. This growth comes from rising awareness of both its practical advantages and its environmental value. In terms of performance, rPET is strong, durable, and quick-drying — qualities that make it ideal for sportswear. 39 Beyond performance, rPET supports the environment. Producing it uses 99% less water than producing traditional polyester, an important benefit for water-stressed regions involved in textile manufacturing. It also helps reduce waste. About 25 rPET bottles can be turned into the fibers for one jacket. 40 rPET is not a perfect solution to plastic pollution, but it is a meaningful step toward more sustainable fashion and a cleaner planet. A．It is also lightweight and wrinkle-resistant. B．However, market trends tell a different story. C．The transformation happens through several steps. D．This keeps millions of plastic bottles out of landfills each year. E．Recycling rPET fabric back into new fabric can be challenging. F．While it is safe to wear, it releases microplastics when it is washed. G．Unlike traditional polyester made from petrol, rPET uses existing plastic. 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。 Beckett Zahedi and Derrick Webster Jr. have created a website called Realer Estate. It is a platform 41 to help renters more easily find proper and rent-stabilized apartments in a city where affordable housing costs are often out of 42 . Their goal is simple but powerful — make hard-to-find housing options more 43 to everyday New Yorkers. The project has become an all-consuming 44 for the teens. Outside of school, they’ve 45 their time and energy to the construction of the website, even giving up basketball and spending their last two summers 46 it. Realer Estate brings together public data and real estate (房地产) listings, allowing users to quickly 47 rent-stabilized apartments and units 48 below market value. What is typically a confusing and 49 process for renters is streamlined into one easy-to-use platform. The idea for Realer Estate grew from Zahedi’s personal 50 . He said that seeing how 51 it was to find an affordable apartment after his father got unemployed opened his eyes to how serious the housing crisis is. That understanding 52 in an 11th-grade economics class, where both teens learned more about the scale of the problem. While they 53 their site is just a small step toward solving a much larger issue, the teens remain focused on making a real 54 .

It was May, yet we walked up a snow-covered hill. When we noticed our jeans were wet up to our knees, it did not dampen our spirits Not once did we say, “Let’s turn around.” This was our vacation, and we were on an adventure. Little did we know this was the beginning of many more surprises. The trail was marked as an easy one-kilometer like yet we were already walking a long distance. Our light-heartedness stopped when we came out into a clearing and saw a parking lot without our rental car in it. As my eyes scanned the surroundings, nothing looked familiar. My heart raced. I realized we were lost in a national park that did not officially open for another week. Usually, I am the calm one in the relationship, but my husband surprised me with his calmness. This did not comfort me; in fact, it heightened my fear. As we walked, I asked my husband to call for help, but there was no cell-phone signal in this isolated（偏僻的）area. It was awfully quiet except for our footsteps hitting the road, and my heavy breathing. My husband suggested we conserve energy and walk slower. With each step on the road, my feet and thighs hurt while my mind raced with thoughts about people who got lost in the Canadian woods for days. My vision sharpened. I noticed everything around me: the trees, rocks and snow. I thought we could eat the snow on the ground in case we needed water. For the first time in my life, I was ready and willing to get a ride, but we did not meet with a single car on the road. Silently, I prayed multiple times. We focused on each other, made joint decisions and connected through gratitude. We managed to stay on the main road and walked straight on. Paragraph 1: My husband suddenly spotted a small building on a hill in the distance. __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Paragraph 2: Just then, a friendly woman appeared, saying, “Hello.” __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 原创精品资源学科网独家享有版权，侵权必究！1 1 / 21 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
