Let’s have a look at them together. China’s new high-speed train Fuxing made its first run from Beijing to Shanghai on 21st September, 2017. It ran at a speed of 350 km/h. It’s the fastest train in the world. In China, now you are able to just shop by paying with your smartphone. All you need to do is just scan (扫描) a store’s QR code (二维码). Even a pancake seller on the roadside has a QR code. As for shopping, China has many big online shopping platforms, such as Taobao. It seems that China is really leading in some ways. And we have every reason to believe in an even brighter future. Bike sharing is not a new idea but China has given it a whole new meaning. In China, there are about 10 million shared bikes. People don’t need to find stations to put the bikes. This makes bike sharing much easier. 16．When did the high-speed train Fuxing first run? A．In 2016. B．In 2017. C．In 2018. D．In 2019. 17．How can you pay with your smartphone? A．By telling your phone number. B．By calling the bank. C．By writing your name. D．By scanning a QR code. 18．We can use Taobao for ________.

D．Education. （5） Have you ever used your fingerprint to open a door? Have you ever taken a self-driving taxi on the road? Technologies have brought great changes to our lives. Actually, changes can also be found in your school. “Now, we don’t have to rush to the canteen as soon as the bell rings,” says Hu Liang, a student from Jiangxi. His school introduced a smart canteen system this year. Students choose meals online first. When it’s time for their orders, they pick up meals by using facial recognition (人脸识别) technology. The smart canteen offers students enjoyable experiences. At the same time, it helps the school plan meals and reduce kitchen waste. Besides providing delicious food, the smart school also tries to help students develop good living habits. Recently, a middle school in Chongqing has used four cameras on the playground to follow students and record how fast they run. They can clearly see the top ten students on the screen. That adds fun to running and makes students compete in an interesting way. What other exciting technologies could be part of our lives in the future? Let’s look forward to even more changes! 21．How does the writer start the passage? A．By asking questions. B．By telling stories. C．By comparing the facts.

A report shows that in 2023, 9.58 million Chinese-made EVs were produced and 9.49 million were sold. Among these, 1.2 million EVs were sold to other countries. The Chinese government encourages the use of EVs as part of its plan for green development. Because of this, China’s EV industry is growing very fast. We can see how much this industry has changed. In 2004, at a big car show called Auto China, only one company, BYD, showed its EVs. However, at the 2024 Auto China, there were 278 different EV models from many brands like BYD, SAIC, Geely, Li Auto, Nio, and Xpeng. The EV industry in China now has both difficulties and opportunities: In 2023, 71% of EV brands lowered their prices. Companies that cannot innovate will face more problems. To make cars that are both green and smart, Chinese EV makers are working hard to improve technologies, such as better batteries and AI. At the same time, the government is building more charging points. Also, more Chinese people are becoming aware (意识到) of environmental problems, which encourages them to choose EVs. Electric cars are the future. In a perfect world, everyone would benefit from innovation and green transportation. Some countries or companies might succeed earlier than others and get greater rewards. It is very possible that China will keep its leading position in this race. 26．How many Chinese-made EVs were sold inside China in 2023? A．8.29 million. B．8.38 million. C．9.49 million. 27．What does the underlined word “innovate” mean in the passage? A．To improve old technologies and create new things. B．To get strong support from the government. C．To make people aware of environmental problems. 28．What is the main challenge for EV makers mentioned in the passage? A．The need to keep creating new things. B．Not having enough charging points. C．The government’s strict rules. 29．Why are more people in China choosing to buy EVs? A．Because the government forces people to buy them. B．Because they are the cheapest cars on the market. C．Because people care more about the environment now. 30．What is the writer’s attitude towards the future of China’s EV industry? A．Hopeful. B．Worried. C．Doubtful. （7） Have you ever heard of “digital embroidery” (数字刺绣)? It is a modern way to keep the traditional Chinese art of embroidery alive. In the past, embroidery required artists to spend months sitting in front of a frame, using needles and silk threads to create beautiful patterns. However, due to its complexity and the time it took, fewer young people were willing to learn this skill. To change this, a team of college students from Zhejiang University developed a special machine. They combined computer programming with traditional embroidery techniques. First, users can draw any pattern they like on a tablet or even upload a photo. Then, the computer software translates the image into instructions for the embroidery machine. Within minutes, the machine uses robotic arms to control the needles, stitching (缝纫) the pattern onto the cloth perfectly. “Our goal is not to replace human artists,” said Li Hua, the team leader. “Instead, we want to lower the barrier (门槛) so that everyone can experience the joy of creating embroidery. We also use eco-friendly threads that are stronger and brighter than traditional ones.” The team has already donated several machines to rural schools. Students there can now design their own school badges (徽章) or small gifts using the digital embroidery machine. It turns out that technology can be a bridge connecting the past and the future, helping old ideas find new life in the modern world. 31．Why were fewer young people willing to learn traditional embroidery according to Paragraph 1? A．Because it was too boring. B．Because it needed expensive tools. C．Because it was complex and time-consuming. D．Because it was not popular anymore. 32．What is the correct order of using the digital embroidery machine? ① Upload a photo or draw a pattern. ② The machine stitches the pattern. ③ The computer translates the image into instructions. A．①→②→③ B．①→③→② C．③→①→② D．②→①→③ 33．What does the underlined word “eco-friendly” in Paragraph 3 most probably mean? A．Harmful to the earth. B．Expensive to buy. C．Good for the environment. D．Similar to the old style. 34．What is the main purpose of developing this digital embroidery machine? A．To sell more embroidery products online. B．To replace human embroidery artists completely. C．To help students in cities get higher grades. D．To make embroidery easier and attract more learners. 35．Where is the passage most probably taken from? A．A travel guide. B．A science magazine. C．A story book. D．A cooking recipe. （8） When we think of inventors, we usually imagine old men in white coats surrounded by wires and tools. However, 17-year-old Emma Rodriguez from Miami is changing that image. She recently invented a low-cost water purification (净化) device that is now being used in several remote villages in South America. Emma’s journey started two years ago during a geography lesson. Her teacher showed a video of children drinking dirty water, which led to serious health problems. Emma was shocked. “I thought, ‘This isn’t fair,’” she recalled. “I wanted to do something to help.” She began researching water purification methods online. Most existing devices were too expensive or required electricity, which many villages lacked. Emma decided to focus on a solar-powered solution. Using a second-hand microscope she bought with her pocket money, she studied how UV (紫外线) light kills bacteria. She then spent months designing a small, portable device shaped like a water bottle. The biggest challenge was the cost. To keep it affordable, Emma used recycled plastic and a cheap UV LED light. She tested over fifty designs. Once, her device leaked (漏水) during a test, soaking her notes. “I felt like crying,” she admitted, “but I knew giving up wasn’t an option.” Finally, she succeeded. Her device can clean one liter of water in just 15 minutes using only sunlight. It costs less than $5 to make. An international charity organization noticed her work and helped her send 500 units to Colombia. Local residents say the device has greatly improved their health. Emma has no plans to patent her invention for profit. Instead, she has open-sourced her design online, allowing anyone to download and produce it for free. “Ideas should be shared, especially when they can save lives,” she says. “I hope more teens realize that age is just a number. If you see a problem, you can be the one to solve it.” 36．What inspired Emma to invent the water purification device? A．A lesson about health problems. B．A video shown in a geography class. C．A visit to remote villages in Colombia. D．An article about solar energy technology. 37．What is Paragraph 3 mainly about? A．How Emma solved the funding problem. B．Why Emma chose UV light for her device. C．The process of Emma’s invention and design.

C．She was determined to continue. D．She was allowed to stop working. 39．Which of the following words can best describe Emma? A．Humorous and quiet. B．Honest and friendly. C．Creative and selfless. D．Brave and noisy. 40．What can we infer from the last paragraph? A．Emma will start a company to sell her device. B．Emma wants to keep her invention a secret. C．Emma believes teenagers can make a difference. D．Emma plans to study abroad to learn more about water. （9） As one of China’s most famous inventions, papermaking is a great treasure of ancient civilization, which greatly changed human life. Before its creation, people depended on heavy bamboo slips, expensive silk, or hard animal bones to record information. These materials were either hard to carry or too costly, making it difficult for people to share knowledge widely. The earliest paper dates back to the Western Han Dynasty. It was made from simple plant materials like hemp and rags (麻类和破布), but the quality was not good enough for daily use. This invention slowly developed, and people kept trying to find better ways to make paper. During the Eastern Han Dynasty, Cai Lun made a major improvement in papermaking. He used common and easy-to-get materials such as bark, straw, and old fishing nets. This change made paper cheaper and more practical. Soon, paper became popular among people, greatly pushing the development of education and culture. Papermaking later spread to other countries through trade and cultural exchange. It first reached Asian countries, then spread to Europe, and finally to all parts of the world. Even today, paper remains an important part of our daily life, from books to documents. This ancient Chinese invention still shows its lasting value in connecting people and spreading knowledge. 41．How does the writer start the passage? A．By telling a story. B．By making a comparison. C．By giving an opinion. D．By offering a suggestion. 42．The passage is mainly written in the order of ________. A．ideas B．time C．places D．persons 43．What was the problem with the earliest paper in the Western Han Dynasty? A．It was too heavy to carry. B．It was made from expensive materials. C．It could not record information clearly. D．Its quality was not suitable for daily use. 44．Why did Cai Lun’s improvement make paper popular? A．He used rare and valuable materials. B．It made paper more expensive but better. C．It made paper cheaper and more practical. D．He was a famous inventor in the Eastern Han Dynasty. 45．Which of the following is true about the last paragraph? A．Papermaking spread to Europe first. B．Papermaking only spread within Asia. C．Paper is no longer used in modern life. D．Trade helped papermaking spread globally. （10） Have you ever seen or used a saw, or ju in Chinese? Do you know who invented it? The inventor was Lu Ban. He was born in the state of Lu in ancient China more than 2,500 years ago. That is where Qufu lies in the east of Jining. Lu Ban was the greatest carpenter (木匠) in his time. Once the king ordered him and his team to build a palace in a very short time. They would be punished if they missed the deadline (最后期限). They had only axes, or fuzi in Chinese, to cut the trees and prepare the wood for the palace, so the work went very slowly. One day Lu Ban rushed up the hill to see how things were going. Suddenly the sharp teeth of a leaf cut his hand. Then a bright idea came into his head. Soon he made a tool with teeth along the side of a long iron bar (条状物). With this tool, work became much faster, and they completed the work before the deadline. That is how the saw was invented. Lu Ban invented many other useful tools for carpenters and interesting toys for children. The Wooden Bird, for example, could stay in the air for three days! 46．In which picture can you see a saw?

Let’s learn about its amazing features! How big is it? The AG600 has a wingspan (翼展) of 38.8 metres and is 36.9 metres long. That’s about the size of a Boeing 737! It can carry up to 50 passengers or 12 tonnes of water. What can it do? • Fighting Forest Fires: It can scoop up (舀取) 12 tonnes of water from a lake or river in just 20 seconds and drop it on a forest fire. • Maritime Rescue: It can search for ships in trouble and rescue up to 20 people at a time. It can land on both water and ground, making it very flexible. • Environmental Monitoring: It can be used to check the ocean for pollution and protect marine life. Why is it important? The AG600 shows China's advanced technology in aviation (航空). It can operate in complex weather conditions and remote areas. With its powerful engines and special design, it plays a key role in China's emergency rescue system. Would you like to see this giant plane one day? Maybe you can become an engineer and build even more amazing aircraft in the future! 51．How does the writer show the size of the AG600 in Paragraph 2? A．By asking questions. B．By listing numbers. C．By giving suggestions. D．By telling stories. 52．What may we NOT enjoy about the AG600 according to the text? A．Fighting forest fires. B．Maritime rescue. C．Environmental monitoring.

D．Worried. （12） A hundred years ago, it was difficult for people to communicate over long distances. Then Samuel Morse invented the electric telegraph and the Morse code (摩斯密码). Morse code is a series of dots and dashes. The dashes are about three times longer than the dots. Here is the code for the letters of the alphabet. The Morse code also includes codes for numbers and punctuation signs (标点符号). Like texting, it also has groups of letters that stand for phrases. For example, the letters CUL stand for “see you later”. And the famous SOS signal stands for “save our souls” The electric telegraph could send messages using electricity. The worker at one end used a machine to tap (敲击) out a special code for each letter of the alphabet. The system changed the tapping into electrical movements and sent them to another place. Then they were changed back into the code at the place. The code was printed on a paper tape which was set on another machine. The worker on the receiving end used the code to change the message back into words. Later, workers learned to translate the code just by listening. Today Morse code is used mostly by radio workers. Some pilots flying planes by instruments use Morse code to decide their lane’s location. But perhaps the most exciting use of Morse code is helping disabled people communicate. There have been cases in which people have learned to communicate using their eyelids to send messages using Morse code. Or they have used a finger to tap out messages. 54．What does the code “” stand for? A．JOY. B．LOVE. C．LUCK. D．WARM. 55．What does the underlined word “they” refer to in Paragraph 4? A．The letters. B．The messages. C．The special codes. D．The electrical movements. 56．Which of the following sentences is TRUE? A．The dots are three times longer than the dashes. B．The Morse code also includes codes for phrases. C．Messages can only be sent by the Morse code using electricity. D．Before the code was printed, the message was changed back into words. 57．What may the writer most probably talk about next after the last paragraph? A．The possible use of Morse code in the future. B．The history of how Morse code was invented. C．The difference between Morse code and other communication methods. D．The famous SOS signal and its meaning in Morse code. （13） In recent years, China has introduced unusual inventions that are changing daily life and catching global attention. These inventions, often called the “New Four Great Inventions,” include high-speed rail, mobile payment, shared bikes, and online shopping. Unlike the ancient four great inventions—papermaking, printing, the compass, and gunpowder—these modern wonders connect closely to digital (数字的) technology and convenience. High-speed rail networks have completely changed travel within China. These trains glide (滑行) smoothly at speeds over 300 kilometers per hour, making long journeys between cities surprisingly fast and comfortable. They have become a symbol of China’s engineering progress and a preferred way of transport for millions of passengers each day. Mobile payment platforms allow people to pay for almost anything using just their smartphones. By scanning (扫描) a simple QR code in shops, restaurants, or even street vendors (小贩) , transactions (交易) are completed in seconds. This technology has made carrying cash almost unnecessary, offering great convenience and reducing the risk of loss. Shared bikes, easily unlocked with a mobile app, provide a simple solution for short trips. They help reduce traffic jams and are an environmentally friendly choice. Similarly, online shopping has changed how people buy goods, offering endless choices sent directly to one’s doorstep, often within days or even hours. These new inventions show that China is changing. It used to make traditional things, but now it is leading in making high-tech solutions. These solutions can solve real problems in our lives. They show how technology can make life simple, save time, and connect people to services more efficiently. 58．What is the main purpose (目的) of the article? A．To explain the history of China’s ancient inventions. B．To compare high-speed trains with shared bikes. C．To argue that mobile payment is the most important invention. D．To describe how China’s latest inventions are influencing modern life. 59．Why does the writer mention ancient inventions in the first paragraph? A．To give a history lesson.

C．They are not useful for everyday life. D．They are more important than the ancient inventions. （14） Students at Changchun University of Science and Technology have invented a device (设备) that can turn the pages of a book with just the blink (眨眼) of eyes. “The invention, which uses brain-sensing (脑感应) technology, could make it easier for disabled people or the elderly to read books in a smart way,” Qi Huanqiang, one of the inventors, said. The team of five students was from the university’s electrical information and engineering school and said they came up with the plan in a week. The team showed the device at a special event at the university. Qi wore a headband (头带) and every time he blinked three times in two seconds, the device turned a page of a book. He said the headband can sense brain waves and turn them into digital signals (数字信号). Then the digital signals were sent to the device that can turn the pages. Qi also said the invention was not expensive and could help a lot of people. It quickly became popular online. And many people also encouraged the young inventors to make the device even better. ▲ One person said that the device could not turn pages backwards and that it was not very practical. Another said, “I don’t think it’s helpful. That means I can’t blink at all until I’ve finished reading a page.” This invention, though not perfect, is still a good thing. The inventors want to help people, and that’s a good lesson for all science lovers. It’s a great start and with more work, who knows what amazing things they might create next! 63．What is the team’s purpose in inventing the device? A．To test brain waves. B．To warn of a health risk.

It connects Xining to Lhasa, a huge distance of 1,956 kilometres, and it is the highest railway in the world, reaching 5,072 metres above sea level at Tanggula Pass. The building of the railway was a great challenge. Creative ideas were needed to solve different problems. In summer, the top layer of the frozen ground would melt and become too soft to build on, so pipes were used to keep the ground hard. However, in some places, it was impossible to build the railway over the frozen ground, so tunnels had to be created instead. In some other places, bridges were built to keep the railway up above the ground. These bridges are animal-friendly and allow animals to pass under the tracks. The railway has brought many benefits. It has increased tourism and economic development in the area. People now can travel more easily between the cities. The lessons learnt and experience gained from building this railway will help improve transport in other similar places in the world. This project is a great example of how creative ideas can solve difficult problems. It shows that with determination and smart thinking, even the hardest tasks can be achieved. 68．What is the altitude of the Qinghai-Xizang Railway at Tanggula Pass? A．1,956 metres. B．5,072 metres. C．2,006 metres. D．1,900 metres. 69．Why did engineers use pipes in some places during construction? A．To carry water. B．To keep the frozen ground hard. C．To build tunnels. D．To help animals pass. 70．What were built to allow animals to pass under the tracks? A．Tunnels. B．Pipes. C．Bridges. D．Railways. 71．What benefits has the railway brought to the area?

Many people have creative thoughts, but few turn them into reality. 1 First, write your idea down. 2 When you put your idea on paper, you can see it more clearly and begin to develop it. Second, do your research. Find out if someone else has already created something similar. 3 Learning from others can save you time and help you improve your own work. Third, take action. Many people dream of making something new but never start. 4 Don’t be afraid to fail—every failure teaches you something valuable. Finally, share your idea with others. Feedback can help you see things you might have missed. 5 Sometimes a different point of view can make your idea much better. Remember, every great invention started as a simple idea. The key is not just having the idea, but taking steps to make it real. A．If so, don’t get discouraged—you can still make it better. B．Even the best ideas can be forgotten if they’re not written down. C．So how do we turn our ideas into real things? D．The most important step is to begin—even if it’s just a small step. E．Always keep your ideas secret from others. F．They can also give you suggestions you haven’t considered. （2） 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有一项是多余的。 In the ice cap region near China’s Zhongshan Station in Antarctica, a six-legged robotic dog recently completed some scientific tests successfully. A video shows the robotic dog is walking on the snow and ice. 6 The developers designed a special type of shoes for the robotic dog. “ 7 So it can get used to the low temperatures of Antarctica. Also, when it touches the ice, the pressure it puts out becomes very small and causes little damage to the ice surface. This ensures the robotic dog can walk on the ice as if it were level ground.”, said Mao Shijie, the head of the six-legged robotic team. 8 This lets it work for two hours even in the cold Antarctic temperature. But this action alone isn’t enough. So, the scientific team looks for more advanced ways to make its battery life longer. “For scientific research, we usually need it to work for more than four hours. 9 In such cases, we add two additional batteries on top of the robotic dog, ensuring it can keep working for 4-6 hours.” Mao added. According to CCTV, the six-legged robotic dog has now successfully completed tests such as carrying heavy things on the ice surfaces of Antarctica. 10 The research team said that the robotic dog will be improved to meet other needs of the scientific research teams in the future. A．The robot is so heavy that it can’t move fast. B．It is carrying a box on its back, without falling. C．It can carry things weighing from 70 to 100 kilograms. D．No matter how cold it is, we often do ice surface research. E．The robotic dog not only has specially designed shoes but also a special battery. F．The material of the shoes itself can stand as low as -40℃. （3） 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有一项是多余的。 Many middle schools now hold “Idea Competition” every year to encourage students to think of creative ways to improve school life. 11 You don’t need to make a real product to join the competition — even a small smart idea is enough. Last year, 14-year-old Li Hua from No.3 Middle School noticed that students often forgot to take their umbrellas when it rained suddenly. 12 She suggested that the school put shared umbrella stands at each teaching building gate, with 20 umbrellas each. Students can take an umbrella for free when it rains and return it later. 13 Now the shared umbrella stands are already in use in her school, and almost 300 students have used them this term. Another student, Zhang Wei, found that the books in the school corner were old and not popular. 14 He suggested setting up a book exchange box: students can bring their old books to the box and take away other books they like. The idea was welcomed by both teachers and students. Now there are over 200 new books in the exchange box. 15 Even a small idea can make a big difference to your school. Next time you notice a small problem in your school, think about how to solve it — maybe your idea will become real too! A．He came up with an idea to make the book corner more popular. B．The competition asks students to find small problems in school and think of solutions. C．So she thought of a great idea to solve this problem. D．There are many other great ideas from the competition every year. E．Her idea was praised by the school headmaster immediately. F．Many students don’t like reading books at school. （4） 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有一项是多余的。 Accidental Inventions Many great inventions were not planned. They happened by accident. 16 One of the most famous examples is the invention of sticky notes. In 1968, a scientist was trying to make a strong glue. Instead, he produced a weak glue that could stick and be removed easily. 17 But he didn’t give up on it. A few years later, another man was trying to mark pages in his song book. 18 Then he remembered the weak glue. He applied the glue to small pieces of paper, and the sticky note was born. 19 Today, they are used in offices, schools, and homes all over the world. The sticky note is a great example of how a mistake can lead to something wonderful. 20 Who knows what other great inventions are waiting to be discovered by mistake? A．His small pieces of paper kept falling off the pages. B．At first, no one could think of a use for it. C．The sticky note quickly became popular. D．Sometimes the best ideas come from mistakes.
