He lived more than 2,000 years ago, during the Spring and Autumn period. Known as a highly skilled carpenter (木匠), he created a number of tools that greatly helped people’s lives and work. Many important tools we still use today were invented by Lu Ban, such as the saw (锯), the drill (钻头), and the shovel (铲子). There is an interesting legend (传说) about how he got the idea for the saw. One day, when he was working in the forest, his finger was cut by a sharp blade of grass. He looked closely and found the grass had tiny, sharp teeth. Inspired (启发) by this, Lu Ban designed a tool with similar teeth to cut wood easily—that was the first saw in history. Besides these tools, Lu Ban also made amazing creations. He invented a “wooden bird” that could fly for three days without landing. Thanks to his great contributions, Lu Ban is still respected and remembered today as the “master of all carpenters” in China. 1．When did Lu Ban live? A．Over 1,000 years ago. B．In the Tang Dynasty.

The Internet has become an important part of our daily life. Many people use it for work, study and entertainment. But do you know how the Internet was invented? The Internet was first developed in the 1960s by the US Department of Defense. At that time, it was called ARPANET. It was designed to connect computers at different universities and research centers. The goal was to share information and keep communication possible even if part of the network was destroyed. In the 1970s, scientists developed a way to send data between different networks. This was called TCP/IP. It became the standard for how data is sent over the Internet. In the 1990s, the World Wide Web was invented by Tim Berners-Lee. This made it easier for people to use the Internet. They could use browsers to view web pages with pictures and text. Today, the Internet connects billions of devices around the world. We can do almost anything online—shop, study, work, communicate and more. The Internet has changed the way we live and work. 1．When was the Internet first developed? A．In the 1950s. B．In the 1960s. C．In the 1970s. D．In the 1990s. 2．What was the original name of the Internet? A．ARPANET. B．TCP/IP. C．World Wide Web. D．Browser. 3．What was the purpose of the Internet at first? A．To connect computers in offices. B．To share information and keep communication. C．To help people shop online. D．To let people play games. 4．Who invented the World Wide Web? A．The US Department of Defense. B．Scientists in the 1970s. C．Tim Berners-Lee. D．Bill Gates. 5．What can we NOT do online according to the passage? A．Shop. B．Study. C．Travel. D．Communicate. Are you tired of doing chores? Imagine a life without folding clothes or carrying heavy bags. That life is here with NEO. NEO is the first “humanoid (类人的)” robot for home use. It looks just like a human. It stands 1.6 meters tall and weighs only 30 kilograms. Because it is shaped like a person, it can work with you like a friend. NEO is smart and helpful. It can clean surfaces (表面) and do most of the housework. It can even make simple conversations with guests at the door. NEO uses Advanced AI and understands voice instructions (指令). You can also plan its tasks through an app on your phone. The robot is light but very strong. It can lift items up to 70 kilograms when it stands still. While walking, it can easily carry 25 kilograms. Also, its power system is automatic (自动的), so you don’t have to worry about it all day. When the battery is low, it finds the charger (充电器) by itself. You might think such a strong machine would be loud. But NEO is different. It makes only 22 decibels (分贝) of sound. This is as quiet as a fridge. It has a soft body and smart sensors (传感器), so you can trust it with children and pets. Of course, such smart technology is expensive. The price is now $20,000. However, users can choose to pay a monthly fee of $499. You can also pick a color, like gray or dark brown. For buyers in the U.S., delivery (派送) starts in 2026. Although the price is high, this invention (发明) could change lives for the old or busy families. It is a big step toward a smarter, easier world. 1．According to the article, NEO can do all the following things except ________. A．cleaning surfaces B．folding our clothes C．doing our office work D．talking to people at the door 2．How can the user control (控制) NEO? A．By connecting it to the charger. B．By using the sensors on its body. C．By teaching it to act like a human. D．By speaking to it or using an app. 3．When can NEO lift the heaviest weight? A．When it is walking. B．When it stands still. C．When its battery is full. D．When the user orders through the app. 4．Why does the author compare NEO to a fridge? A．To show that the robot is heavy. B．To explain why NEO has a soft body. C．To help readers know how quiet NEO is. D．To show that NEO belongs in the kitchen. 5．How does the writer think of NEO? A．It is too expensive to be useful for anyone. B．It is unsafe for families with children and pets. C．It is not good enough because the delivery is late. D．It will make life better, even though it is not cheap. A group of college students in Nanjing invented a solar-powered (太阳能驱动的) charging bag for rural students. The bag can solve the problem of power shortage in some mountain areas. The bag looks like an ordinary schoolbag, but it has a special solar panel on the back. When exposed to sunlight for 4 hours, it can store enough electricity to charge a mobile phone twice or a tablet once. The bag is also waterproof (防水的) and durable (耐用的), so it’s suitable for outdoor use. Why did the students invent this bag? They visited a rural school last summer and found that many students couldn’t study at night because there was no electricity. Some students even had to walk a long way to charge their devices. “We wanted to help them study better,” said the leader of the invention team. The invention has won a prize in a national innovation competition. Now the students are working with a company to produce more bags. They plan to donate 500 bags to rural students in Guizhou and Yunnan provinces next year. “We hope our invention can bring light to their study and life,” said one of the inventors. 1．What is special about the solar-powered charging bag? A．It can be used as a tablet. B．It has a solar panel on the back. C．It is smaller than an ordinary schoolbag. D．It can charge a mobile phone in 4 hours. 2．The solar-powered bag can solve the problem of ________ in rural areas. A．food shortage B．water pollution C．power shortage D．traffic jam 3．The students invented the bag because they ________. A．wanted to win a competition B．wanted to make money C．needed it for their own use D．wanted to help rural students study better 4．How many bags do the students plan to donate next year? A．1000 B．300 C．500 D．100 5．What can we infer from the passage? A．The bag is not suitable for outdoor use. B．The students will produce the bags by themselves. C．The invention is helpful to rural students. D．The solar panel can store electricity without sunlight. The German scientist Wilhelm Conrad Röntgen wanted to use tubes to do experiments on electricity. The tubes were covered in heavy black paper. He was surprised to see a green light coming from the tubes. And he was even more surprised when the light appeared on a screen beside him. How strange! He learned that the light can pass through objects. Röntgen knew he discovered something important. When he passed the light through his wife’s hand, something exciting happened. He could see the bones inside her hand! This was how Röntgen discovered X-rays in 1895. After many tests on humans, they were soon widely used in hospitals and Röntgen was awarded the Nobel Prize. The British scientist, Sir Alexander Fleming, discovered penicillin by accident. In 1928, he went on a holiday but forgot to clean up his lab before he left. When he got back, he found some strange mould growing on some of his Petri dishes. To his surprise, the mould seemed to stop the bacteria around it from growing. With more research, he discovered penicillin. Later, other scientists turned penicillin into life-saving medicine. The discovery of penicillin changed the course of medicine and has made it possible for doctors to treat serious illnesses. What an amazing discovery! Around 1970, when a lot of people were getting sick with malaria, Tu Youyou was chosen to find a medicine. She read a large number of ancient Chinese medical books and discovered a treatment using a plant called qinghao. However, no matter how hard they tried, Tu and her team failed to get the active part from the plant. Tu took another closer look at the medical classics. Finally, one line lit up an idea for her—a low-heat method! With this method, she and her team successfully got the active part and named it qinghaosu. Tu volunteered to test the medicine on herself before giving it to others. Later, qinghaosu became an important treatment for malaria and has saved millions of lives. Tu called the discovery “a gift from Traditional Chinese Medicine to the world”. 1．What did Röntgen discover when doing electricity experiments? A．Penicillin. B．X-rays. C．Qinghaosu. D．A new kind of tube. 2．How did Fleming discover penicillin? A．He studied ancient medical books. B．He used a low-heat method. C．He forgot to clean his lab before holiday. D．He tested plants from tropical areas. 3．Why did Tu Youyou use a low-heat method? A．To get the active part from qinghao. B．To test the medicine on herself. C．To write medical books. D．To win the Nobel Prize. 4．Which of the following is TRUE about the three discoveries? A．X-rays were first used to treat malaria. B．Penicillin was turned into life-saving medicine by Fleming alone. C．Qinghaosu is a gift from Traditional Chinese Medicine. D．All the three discoverers won the Nobel Prize. 5．What do the three scientists have in common? A．They all studied ancient books. B．Their discoveries changed medicine. C．They all discovered medicines by accident. D．They all tested their discoveries on themselves. 进阶拓展训练5篇 Not real, but does the jobSpecial “plants” were made to keep indoor air fresh. Like real plants, they use indoor light to do photosynthesis (光合作用), turning CO2 into O2. Tests show that they can take in about 90% of CO2 from the air. That is much more than real plants, which only take in 10%. DNA tape stores many songsBy using DNA, a team of Chinese scientists created a tape to store songs. The team printed man-made DNA on the tape to save the songs’ information. A 90-meter section of this tape can hold more than 3 billion songs. The scientists hope this technology could one day take the place of those big information centers that use lots of electricity (电力). Mouse-like robot movesA mouse-like robot with a backbone (脊柱) that can bend easily was created recently. There are 8 small parts on its back to help it bend. So it moves more easily like a mouse. It corners better than common robots. One day, such bendable robots may go to small places where humans can’t go to help do search tasks. 1．In which SECTION of the newspaper can we read the news? A．ART. B．MUSIC． C．SCIENCE. D．NATURE. 2．Why were the special “plants” made? A．To make rooms nice. B．To let out more CO2. C．To improve indoor air quality. D．To help real plants grow. 3．What can we know about the tape according to the second news? A．It needs a lot of electricity. B．It records the information of songs. C．It was printed by a scientist team. D．It works as a big information center. 4．In the third news, the underlined word “bend” is closest in meaning to ________. A．stop suddenly B．jump high C．move forward D．change shape 5．What is the news above mainly about? A．Amazing creations. B．Wonderful world. C．New findings. D．Future life. US company Motorola created the first cell phone in 1973. That phone was as big as a brick and could only make calls for 30 minutes. Today, we have 5G smartphones that look very different and can do much more. What will the phones be like in the future? Most foldable phones today can only fold the screen up and down or left and right. But in the future, phones will be easier to bend (弯曲). Motorola makes a new phone. People can wear it like a bracelet (手环) and bend it into different shapes. Apple is also working on a way to make foldable screens with fewer creases (折痕). In the future, phones will not only bend easily, but also they will be able to fix themselves. Professor Zhenan Bao from Stanford University made an electronic skin. It can fix itself with heat and magnets (磁). This skin acts like human skin, stretching (拉伸) without breaking. If we use it to make phones, the phones could fix scratches (划痕) by themselves. People will also power phones in new ways such as using solar energy (太阳能). In 2016, Kyocera Corporation from Japan and French company Sun Partner Technologies made a phone with solar panels (电池板) in the screen. It took three minutes of sunlight to charge (充电) for one minute of talk time. But it still needed traditional batteries (电池). In the future, faster and independent solar charging will make solar-powered phones more popular. 1．What’s special about Motorola’s new phone? A．It looks like a brick. B．It’s the first foldable phone. C．It can make calls for longer. D．It can bend into different shapes. 2．What can the electronic skin do for phones? A．It can fix the phone’s scratches by itself. B．It can keep the phone’s heat low. C．It can protect the users’ skin. D．It can make the screen fold easily. 3．What do we know about the 2016 solar-powered phone? A．It could charge very fast. B．It didn’t need a traditional battery anymore. C．It never ran out of power. D．It only needed 3 minutes to charge fully. 4．What does the underlined word “It” refer to in Paragraph 4? A．The solar panel. B．The talk time. C．The sunlight. D．The phone with solar panels in the screen. 5．What is the structure of the passage? A．①/②/③/④ B．①/②③④ C．①/②③/④ D．①/②/③④ Did you ever wish you could show your dreams to your friends or family? Now you might be able to, with a new tool that uses AI to create videos from spoken words. The Dream Recorder, created by the Dutch design studio (工作室) Modem, is a bedside tool that lets you record your dreams and play them back as short videos. The idea is that as soon as you get up, you push a record button (录音按钮) on the Dream Recorder and speak into it — in any language — telling what you remember of your dream. Then AI technology (技术) will then try to interpret your spoken dream and create a short video based on it in a visual style (视觉风格) you want. You can then play back this video on the Dream Recorder’s screen. However, you can’t keep these dream videos forever, because the Dream Recorder only has enough memory for seven days of dreams. That should be long enough to see if there are any of the same ideas show up again and again in your dreams, while keeping your mind in the present. Modem is an unusual design studio because it has set itself an end date in 2030. This is meant to encourage the designers to take chances, experiment and create work that is focused on the present moment. 1．How does the writer begin the passage? A．By giving examples. B．By telling a story. C．By asking a question. D．By doing a survey. 2．What does the underlined word “interpret” in Paragraph 3 mean? A．understand B．separate C．choose D．add 3．What is Dream Recorder? A．It’s a visual style. B．It’s a bedside tool. C．It’s a design studio. D．It’s an experiment. 4．Why has the design studio Modem set itself an end date? A．It plans to create lots of works by using AI. B．It expects to focus on dream recording tools. C．It hopes to push its designers to try different and new things. D．It wants to make more and more dream recorders for people. 5．What’s the best title for the passage? A．A Smart AI Tool for Making Dream Videos B．Modem, A Design Studio with a Special Plan C．The Simple Steps to Use the Dream Recorder D．The Way to Keep Your Mind in Sweet Dreams Jia Mingxuan, a 14-year-old Chinese boy from Inner Mongolia, won a top honor (荣誉) with his own creation in Germany. His idea grew from his childhood experiences in Chifeng, a key area in China’s Three-North Shelterbelt Forest Program (三北防护林工程). The program forested many deserts, however, with a little rainfall in a whole year, it’s slow, costly and sometimes even impossible to water all the trees by people. The chance knocked when his science teacher asked the class to create something. The idea came in an unusual place — his family kitchen. One evening, he saw steam condensing (蒸汽冷凝) into water drops on the wall. He remembered what he learned at school and asked himself: “Could I use this to water trees?” His hand-made creation can water young trees by itself. It collects water steam from the air and turns it into water with the help of the temperature difference. Then the water will drop to the roots of a tree. Jia tried his best for the idea. Sometimes he woke up at 4 a.m., hurrying home to try out the things he made and hurrying back for his everyday classes. His goal is clear—to turn his small idea into a useful tool in China’s fight against desertification. He said, “I need to study harder. With more knowledge, I can make better things.” 1．Why was it impossible to water all trees in Chifeng? A．Because people have no time. B．Because the forest grows too slowly. C．Because it rains very little in a year. D．Because the weather is hot in deserts. 2．What does the underlined word “this” in Paragraph 2 refer to? A．The chance to create. B．The water came from steam. C．The unusual place. D．The knowledge he learned. 3．What does Jia’s creation mainly do? A．It makes a temperature difference. B．It plants trees by itself. C．It collects the steam to water trees. D．It uses rainwater for drinking. 4．What was Jia’s goal according to the passage? A．To create a tool to fight against desertification. B．To finish the science teacher’s homework. C．To win more top honors in Germany. D．To build a program in the key area. 5．Which of the following can best describe Jia Mingxuan? A．Friendly and honest. B．Pleasant and outgoing. C．Active and confident. D．Creative and hard-working. Have you ever had a big dream? Did others think it was impossible? What did you do then? A 15-year-old boy set a good example for us. The boy named Li Banghua, from Hefei in East China’s Anhui Province, designed and built a drone (无人机) completely by himself. The drone is 0.6 meters wide, has a wingspan (翼展) of 4.4 meters and weighs about 40 kilograms. He started this right after his high-school entrance exams (中考) , and worked on it during the whole summer holiday. The young boy has loved airplanes since he was a child. “I have studied and built drones for years,” Li said. “but this time the drone is the largest I have ever built and it is also my most successful one.” However, the journey of making drones was not smooth. Perhaps his biggest challenge wasn’t technical—it was getting people to believe in him. “Many adults just didn’t understand my dream,” Li explained. “They thought I was wasting my time. Because of this, I even had to pretend (假装) to be an adult online to buy materials (材料).” The building process (过程) was difficult. “I failed seven or eight times,” he said. “I felt very frustrated. But I never thought about giving up. When you start something important, you should finish it.” 1．How does the writer begin the story? A．By talking about a dream that is hard to achieve. B．By showing the size and weight of the drone. C．By telling us who the boy is and where he is from. D．By asking the readers some questions first. 2．Which one is TRUE about the drone Li built? A．It is 0.6 meters long with a 4.4 meters wingspan. B．It weighs about 40 kilograms and is 0.6 meters wide. C．It took over one year to build this large drone. D．He built it with his teacher’s help after exams. 3．What does the underlined word “smooth” mean? A．Without problems or difficulties. B．Quick and fast in progress. C．Safe and free from danger. D．Happy and full of enjoyment. 4．What was the biggest difficulty about his project? A．He couldn’t find good materials to build the drone. B．Building problems were too hard for him to solve. C．Many adults didn’t understand or support his dream. D．His parents refused to give him money for materials. 5．What can we learn from his story? A．Starting young makes success easy. B．Family’s support helps achieve dreams. C．Keep trying and you will succeed. D．Working alone makes projects better. 能力综合实践5篇 One day you pick up your phone for a video call with a friend. Not only can you see his face and hear his voice, but you can also smell the cookies he has just baked. It sounds like something out of a science fiction movie, but could it actually happen? Smells are created by tiny particles called molecules (分子) that float through the air and reach your nose. Your nose then sends signals to your brain, which recognizes the smell. So, could your phone send smell molecules to you so that you know what it is? Think about how your phone screen works. It doesn’t have every color in the world stored inside it. Instead, it uses just three colors to create millions of different hues and shades. Now imagine something for smells. Scientists are developing digital scent (香味) technology that uses a number of different cartridges (盒；匣), each containing a specific scent. Just like how pixels (像素) mix red, green and blue to create images, these scent cartridges could mix to create different smells. Images on your phone are made of digital codes that represent mix of pixels, and smells are created in the same way. When you receive a digital scent code, your phone could mix tiny amounts of the different scents from the cartridges to create the desired smell. This mix would then be released through a small vent (通风口) on the phone, allowing you to smell it. With a few cartridges, your phone could create a large number of smells. Creating such a phone faces more challenges. One is designing a system that can produce thousands of different smells using a few cartridges. And phones will also need to sense scents near them and change those into digital codes, so your friends’ phones can send smells to you. The cartridges should also be easy to refill, and the chemicals in them be safe to breathe. Even though we’re not there yet, maybe one day you’ll be able to not only see and hear your friend’s birthday party over the phone, but also smell the candles they blew out. 1．How do people smell? Put the following sentences in the correct order. ①Tiny particles reach the nose.    ②The brain recognizes the smell. ③The nose sends signals to the brain.    ④Tiny particles float through the air. A．①④③② B．④①③② C．①③④② D．①③②④ 2．By mentioning how phone screens work, the writer tries to ________. A．compare technologies used in showing colours and sending smells B．explain the real possibility of making phones send smells C．show that it is easier to show colours on the screen D．introduce the powerful function of future phones 3．Which of the following correctly describes “cartridges”? A．Three cartridges are needed to make different scents. B．Cartridges are able to sense scents around the phones. C．Cartridges create smells according to the digital scent codes. D．Cartridges play the most important role in making smell phones. 4．Which of the following things CANNOT help people to smell with the phone? A．Pixels. B．A vent. C．Chemicals. D．Cartridges. 5．What can we infer from the passage? A．Pixel technology can be used directly to create digital scents. B．Only in science fiction movies can we see people use smell phones. C．Smell phones send digital scent codes to the brain to make us smell. D．A powerful system needs to be developed to make smell phones a reality. In the 19th century, communication was a slow and laborious process. People relied on handwritten letters, which could take weeks or even months to reach their destination. The invention of the telegraph in the mid-1800s revolutionized communication, allowing messages to be sent over long distances in a matter of minutes. However, it was the advent of the telephone in the late 19th century that truly transformed how people interacted with one another. Fast forward to the 21st century, and communication has become almost instantaneous. With the rise of the Internet and smartphones, people can now send messages, make video calls, and share information with anyone around the globe in seconds. Social media platforms like Facebook, Twitter, and Weibo have further changed the way we communicate, allowing users to share their thoughts, photos, and videos with a wide audience. Despite these advancements, some argue that modern communication lacks the personal touch of handwritten letters. In the past, letters were often carefully crafted, with attention paid to every word. Today, messages are often short and informal, with emojis and abbreviations replacing full sentences. However, others believe that the speed and convenience of modern communication outweigh these drawbacks. The evolution of communication has also had a significant impact on businesses. In the past, companies relied on mail and telephones to communicate with clients and partners. Today, email, video conferencing, and instant messaging have made it easier than ever to conduct business on a global scale. This has led to increased efficiency and productivity, but it has also created new challenges, such as the need to manage large volumes of digital information. As technology continues to advance, it is likely that communication will continue to evolve. Some experts predict that virtual reality and artificial intelligence will play a major role in the future of communication, allowing people to interact in more immersive and personalized ways. Whatever the future holds, one thing is certain: the way we communicate will continue to change, just as it has for centuries. 1．What was the impact of the telegraph on communication in the 19th century? A．It made communication slower and more laborious. B．It allowed messages to be sent over long distances in minutes. C．It replaced handwritten letters entirely. D．It had no significant impact on communication. 2．Which of the following is NOT mentioned as a modern communication tool? A．Social media platforms. B．Video conferencing. C．Handwritten letters. D．Instant messaging. 3．What is the closest antonym for the underlined word “laborious” in the first paragraph? A．Easy. B．Difficult. C．Slow. D．Complicated. 4．Which of the following would be most important to include in a summary of the passage? A．The invention of the telegraph allowed messages to be sent quickly. B．Modern communication is faster but less personal than in the past. C．Virtual reality will change the way we communicate in the future. D．Businesses have benefited from the evolution of communication. 5．What is the main idea of the passage? A．The invention of the telephone revolutionized communication. B．Modern communication lacks the personal touch of handwritten letters. C．Communication has evolved significantly over time, from letters to instant messaging. D．Virtual reality will play a major role in the future of communication. Do you like cycling? Do you want to have a safer and more comfortable cycling experience? LIVALL, a smart helmet maker, is trying its best to do this. EVO21, LIVALL’s latest product, has wide-angle front lights and super-bright 270° back lights. With these lights, cyclists can see the environment around clearly. At the same time, the bright lights will make cyclists easily noticed on the street. There is a sensor (感应器) in the helmet. So whenever you are slowing down or coming to a stop, it will turn on the warning light on the back of the helmet. So cyclists can keep their eyes on the road, instead of worrying about what’s behind them. So, if you like cycling, EVO21 is a good choice for you. Safety is no longer a problem with EVO21’s SOS technology. If there is an accident, you can press the remote (遥控器) on your bicycle. It can send a text message to your family with your exact location. You don’t have to worry about wrong alarms. If you don’t get hurt, or if you drop your helmet, you can stop the alarm in less than 90 seconds with the remote. LIVALL Riding is an app that can connect you with other cycling lovers. So when you see a beautiful sunrise on your morning cycling next time, you can share it with them. EVO21 is waterproof (防水的), so the lights and the remote can work well in any weather. Because of its special shape, the helmet can keep you cool on the way. What’s more, the helmet can work for about 10 hours after being charged. That means you can use the helmet for a week. EVO21 can provide cyclists a safer and more comfortable cycling experience. Why not have one and enjoy your trip? 1．According to Paragraph 2, cyclists are safer with EVO21 because ________. A．cyclists can easily know what’s behind them B．the helmet can turn on the warning light by itself when the cyclist is speeding up C．cyclists can see roads and be noticed clearly D．the back lights come with a sensor 2．What does the underlined word “It” in Paragraph 3 refer to? A．The remote. B．The sensor. C．The app. D．The light. 3．What can be known with EVO21 if there’s an accident? A．Where the cyclist is. B．What part the cyclist hurts. C．Why the cyclist gives the alarm. D．How the accident happened. 4．Why did the writer write the passage? A．To advise people to keep safe while cycling. B．To introduce a kind of smart helmet by LIVALL. C．To help people to learn about SOS technology. D．To ask cyclists to wear a helmet while cycling. 5．What’s the best structure of the text? (P₁=Paragraph 1) A． B． C． D． Sleeping. Eating. Sleeping. Eating again. Life in a pigpen (猪圈) is boring. Nothing ever changes. Sometimes, I can’t help thinking: What do I live for? “Pigs produce pork. Just eat as much as you can!” my roommates told me. “It is sad, but you can’t change it, can you?” But last month, I heard the pigpen owner talking on the phone about something unusual. Some American doctors saved a very sick man by replacing his heart with a pig’s. This had never successfully been done before. My owner sounded excited. I know why. His elderly uncle had been in the hospital for weeks because of a serious heart problem. A heart transplant (移植), the doctors said, was perhaps the best choice for him. However, ___________. Most heart patients have to wait years before they are able to receive a transplant. Some of them die during this long and painful process. The successful operation (手术) in America means that in the future, people can depend on us pigs for healthy hearts. We are easy to raise, and we grow quickly. Sadly, I am just an ordinary pig.

On May 3rd, Yichang Police Station made history by firstly using a “robot police dog” in Hubei. Working with real police dogs, the robot police dog was sent to patrol (巡逻) and do something else. As a newcomer to the police station, the robot police dog interested many onlookers (旁观者). With two large “eyes” on its back, it tries to find anyone with bad intentions (意图). When the robot police dog finds a visitor leaves his bag on a bench, it will say, “Lost thing found.” Because of heavy rain, the policemen made indoor patrol on May 3rd. However, the brave robot police dog still made outdoor patrols. When children saw the robot police dog working in the rain, they even came up to hold an umbrella for it. However, a little water is nothing to the robot police dog. It can work even in temperatures as high as 60℃ or as low as minus (零下) 40℃. The patrols of the robot police dog in Yichang have become more and more popular. People really liked its first work in Hubei. A visitor named Zhang said, “Some elderly people and children may be afraid of real dogs. But this robot dog looks cool and works well.

He lived more than 2,000 years ago, during the Spring and Autumn period. Known as a highly skilled carpenter (木匠), he created a number of tools that greatly helped people’s lives and work. Many important tools we still use today were invented by Lu Ban, such as the saw (锯), the drill (钻头), and the shovel (铲子). There is an interesting legend (传说) about how he got the idea for the saw. One day, when he was working in the forest, his finger was cut by a sharp blade of grass. He looked closely and found the grass had tiny, sharp teeth. Inspired (启发) by this, Lu Ban designed a tool with similar teeth to cut wood easily—that was the first saw in history. Besides these tools, Lu Ban also made amazing creations. He invented a “wooden bird” that could fly for three days without landing. Thanks to his great contributions, Lu Ban is still respected and remembered today as the “master of all carpenters” in China. 1．When did Lu Ban live? A．Over 1,000 years ago. B．In the Tang Dynasty.

The tubes were covered in heavy black paper. He was surprised to see a green light coming from the tubes. And he was even more surprised when the light appeared on a screen beside him. How strange! He learned that the light can pass through objects. Röntgen knew he discovered something important. When he passed the light through his wife’s hand, something exciting happened. He could see the bones inside her hand! This was how Röntgen discovered X-rays in 1895. After many tests on humans, they were soon widely used in hospitals and Röntgen was awarded the Nobel Prize. The British scientist, Sir Alexander Fleming, discovered penicillin by accident. In 1928, he went on a holiday but forgot to clean up his lab before he left. When he got back, he found some strange mould growing on some of his Petri dishes. To his surprise, the mould seemed to stop the bacteria around it from growing. With more research, he discovered penicillin. Later, other scientists turned penicillin into life-saving medicine. The discovery of penicillin changed the course of medicine and has made it possible for doctors to treat serious illnesses. What an amazing discovery! Around 1970, when a lot of people were getting sick with malaria, Tu Youyou was chosen to find a medicine. She read a large number of ancient Chinese medical books and discovered a treatment using a plant called qinghao. However, no matter how hard they tried, Tu and her team failed to get the active part from the plant. Tu took another closer look at the medical classics. Finally, one line lit up an idea for her—a low-heat method! With this method, she and her team successfully got the active part and named it qinghaosu. Tu volunteered to test the medicine on herself before giving it to others. Later, qinghaosu became an important treatment for malaria and has saved millions of lives. Tu called the discovery “a gift from Traditional Chinese Medicine to the world”. 1．What did Röntgen discover when doing electricity experiments? A．Penicillin. B．X-rays. C．Qinghaosu.

That phone was as big as a brick and could only make calls for 30 minutes. Today, we have 5G smartphones that look very different and can do much more. What will the phones be like in the future? Most foldable phones today can only fold the screen up and down or left and right. But in the future, phones will be easier to bend (弯曲). Motorola makes a new phone. People can wear it like a bracelet (手环) and bend it into different shapes. Apple is also working on a way to make foldable screens with fewer creases (折痕). In the future, phones will not only bend easily, but also they will be able to fix themselves. Professor Zhenan Bao from Stanford University made an electronic skin. It can fix itself with heat and magnets (磁). This skin acts like human skin, stretching (拉伸) without breaking. If we use it to make phones, the phones could fix scratches (划痕) by themselves. People will also power phones in new ways such as using solar energy (太阳能). In 2016, Kyocera Corporation from Japan and French company Sun Partner Technologies made a phone with solar panels (电池板) in the screen. It took three minutes of sunlight to charge (充电) for one minute of talk time. But it still needed traditional batteries (电池). In the future, faster and independent solar charging will make solar-powered phones more popular. 1．What’s special about Motorola’s new phone? A．It looks like a brick.

Now you might be able to, with a new tool that uses AI to create videos from spoken words. The Dream Recorder, created by the Dutch design studio (工作室) Modem, is a bedside tool that lets you record your dreams and play them back as short videos. The idea is that as soon as you get up, you push a record button (录音按钮) on the Dream Recorder and speak into it — in any language — telling what you remember of your dream. Then AI technology (技术) will then try to interpret your spoken dream and create a short video based on it in a visual style (视觉风格) you want. You can then play back this video on the Dream Recorder’s screen. However, you can’t keep these dream videos forever, because the Dream Recorder only has enough memory for seven days of dreams. That should be long enough to see if there are any of the same ideas show up again and again in your dreams, while keeping your mind in the present. Modem is an unusual design studio because it has set itself an end date in 2030. This is meant to encourage the designers to take chances, experiment and create work that is focused on the present moment. 1．How does the writer begin the passage? A．By giving examples. B．By telling a story. C．By asking a question. D．By doing a survey. 2．What does the underlined word “interpret” in Paragraph 3 mean? A．understand B．separate C．choose D．add 3．What is Dream Recorder?

His idea grew from his childhood experiences in Chifeng, a key area in China’s Three-North Shelterbelt Forest Program (三北防护林工程). The program forested many deserts, however, with a little rainfall in a whole year, it’s slow, costly and sometimes even impossible to water all the trees by people. The chance knocked when his science teacher asked the class to create something. The idea came in an unusual place — his family kitchen. One evening, he saw steam condensing (蒸汽冷凝) into water drops on the wall. He remembered what he learned at school and asked himself: “Could I use this to water trees?” His hand-made creation can water young trees by itself. It collects water steam from the air and turns it into water with the help of the temperature difference. Then the water will drop to the roots of a tree. Jia tried his best for the idea. Sometimes he woke up at 4 a.m., hurrying home to try out the things he made and hurrying back for his everyday classes. His goal is clear—to turn his small idea into a useful tool in China’s fight against desertification. He said, “I need to study harder. With more knowledge, I can make better things.” 1．Why was it impossible to water all trees in Chifeng? A．Because people have no time. B．Because the forest grows too slowly. C．Because it rains very little in a year. D．Because the weather is hot in deserts. 2．What does the underlined word “this” in Paragraph 2 refer to? A．The chance to create. B．The water came from steam. C．The unusual place. D．The knowledge he learned. 3．What does Jia’s creation mainly do? A．It makes a temperature difference. B．It plants trees by itself. C．It collects the steam to water trees. D．It uses rainwater for drinking. 4．What was Jia’s goal according to the passage? A．To create a tool to fight against desertification. B．To finish the science teacher’s homework. C．To win more top honors in Germany. D．To build a program in the key area. 5．Which of the following can best describe Jia Mingxuan? A．Friendly and honest. B．Pleasant and outgoing. C．Active and confident. D．Creative and hard-working. 【答案】1．C 2．B 3．C 4．A 5．D 【导语】本文主要讲述了来自内蒙古的14岁少年贾明轩，从生活中获得灵感，发明了一款能收集水蒸气浇灌树木的工具，并希望将其用于中国的防沙治沙事业，最终在德国斩获大奖的故事。 1．细节理解题。根据“…with little rainfall in a whole year, it’s slow, costly and sometimes even impossible to water all the trees by people.”可知，赤峰全年降雨量极少，因此无法人工浇灌所有树木。故选C。 2．词句猜测题。根据“One evening, he saw steam condensing into water drops on the wall.

Did others think it was impossible? What did you do then? A 15-year-old boy set a good example for us. The boy named Li Banghua, from Hefei in East China’s Anhui Province, designed and built a drone (无人机) completely by himself. The drone is 0.6 meters wide, has a wingspan (翼展) of 4.4 meters and weighs about 40 kilograms. He started this right after his high-school entrance exams (中考) , and worked on it during the whole summer holiday. The young boy has loved airplanes since he was a child. “I have studied and built drones for years,” Li said. “but this time the drone is the largest I have ever built and it is also my most successful one.” However, the journey of making drones was not smooth. Perhaps his biggest challenge wasn’t technical—it was getting people to believe in him. “Many adults just didn’t understand my dream,” Li explained. “They thought I was wasting my time. Because of this, I even had to pretend (假装) to be an adult online to buy materials (材料).” The building process (过程) was difficult. “I failed seven or eight times,” he said. “I felt very frustrated.

Not only can you see his face and hear his voice, but you can also smell the cookies he has just baked. It sounds like something out of a science fiction movie, but could it actually happen? Smells are created by tiny particles called molecules (分子) that float through the air and reach your nose. Your nose then sends signals to your brain, which recognizes the smell. So, could your phone send smell molecules to you so that you know what it is? Think about how your phone screen works. It doesn’t have every color in the world stored inside it. Instead, it uses just three colors to create millions of different hues and shades. Now imagine something for smells. Scientists are developing digital scent (香味) technology that uses a number of different cartridges (盒；匣), each containing a specific scent. Just like how pixels (像素) mix red, green and blue to create images, these scent cartridges could mix to create different smells. Images on your phone are made of digital codes that represent mix of pixels, and smells are created in the same way. When you receive a digital scent code, your phone could mix tiny amounts of the different scents from the cartridges to create the desired smell. This mix would then be released through a small vent (通风口) on the phone, allowing you to smell it. With a few cartridges, your phone could create a large number of smells. Creating such a phone faces more challenges. One is designing a system that can produce thousands of different smells using a few cartridges. And phones will also need to sense scents near them and change those into digital codes, so your friends’ phones can send smells to you. The cartridges should also be easy to refill, and the chemicals in them be safe to breathe. Even though we’re not there yet, maybe one day you’ll be able to not only see and hear your friend’s birthday party over the phone, but also smell the candles they blew out. 1．How do people smell? Put the following sentences in the correct order. ①Tiny particles reach the nose.    ②The brain recognizes the smell. ③The nose sends signals to the brain.    ④Tiny particles float through the air. A．①④③② B．④①③② C．①③④② D．①③②④ 2．By mentioning how phone screens work, the writer tries to ________. A．compare technologies used in showing colours and sending smells B．explain the real possibility of making phones send smells C．show that it is easier to show colours on the screen D．introduce the powerful function of future phones 3．Which of the following correctly describes “cartridges”? A．Three cartridges are needed to make different scents. B．Cartridges are able to sense scents around the phones. C．Cartridges create smells according to the digital scent codes. D．Cartridges play the most important role in making smell phones. 4．Which of the following things CANNOT help people to smell with the phone? A．Pixels. B．A vent. C．Chemicals. D．Cartridges. 5．What can we infer from the passage? A．Pixel technology can be used directly to create digital scents. B．Only in science fiction movies can we see people use smell phones. C．Smell phones send digital scent codes to the brain to make us smell. D．A powerful system needs to be developed to make smell phones a reality. 【答案】1．B 2．B 3．C 4．A 5．D 【导语】本文介绍了科学家正在研发的数字香味技术，未来手机可能通过混合不同香味盒中的气味来实现远程传递气味的功能。 1．细节理解题。根据“Tiny particles called molecules float through the air and reach your nose.

People relied on handwritten letters, which could take weeks or even months to reach their destination. The invention of the telegraph in the mid-1800s revolutionized communication, allowing messages to be sent over long distances in a matter of minutes. However, it was the advent of the telephone in the late 19th century that truly transformed how people interacted with one another. Fast forward to the 21st century, and communication has become almost instantaneous. With the rise of the Internet and smartphones, people can now send messages, make video calls, and share information with anyone around the globe in seconds. Social media platforms like Facebook, Twitter, and Weibo have further changed the way we communicate, allowing users to share their thoughts, photos, and videos with a wide audience. Despite these advancements, some argue that modern communication lacks the personal touch of handwritten letters. In the past, letters were often carefully crafted, with attention paid to every word. Today, messages are often short and informal, with emojis and abbreviations replacing full sentences. However, others believe that the speed and convenience of modern communication outweigh these drawbacks. The evolution of communication has also had a significant impact on businesses. In the past, companies relied on mail and telephones to communicate with clients and partners. Today, email, video conferencing, and instant messaging have made it easier than ever to conduct business on a global scale. This has led to increased efficiency and productivity, but it has also created new challenges, such as the need to manage large volumes of digital information. As technology continues to advance, it is likely that communication will continue to evolve. Some experts predict that virtual reality and artificial intelligence will play a major role in the future of communication, allowing people to interact in more immersive and personalized ways. Whatever the future holds, one thing is certain: the way we communicate will continue to change, just as it has for centuries. 1．What was the impact of the telegraph on communication in the 19th century? A．It made communication slower and more laborious. B．It allowed messages to be sent over long distances in minutes. C．It replaced handwritten letters entirely. D．It had no significant impact on communication. 2．Which of the following is NOT mentioned as a modern communication tool? A．Social media platforms. B．Video conferencing. C．Handwritten letters. D．Instant messaging. 3．What is the closest antonym for the underlined word “laborious” in the first paragraph? A．Easy. B．Difficult. C．Slow. D．Complicated. 4．Which of the following would be most important to include in a summary of the passage? A．The invention of the telegraph allowed messages to be sent quickly. B．Modern communication is faster but less personal than in the past. C．Virtual reality will change the way we communicate in the future. D．Businesses have benefited from the evolution of communication. 5．What is the main idea of the passage? A．The invention of the telephone revolutionized communication. B．Modern communication lacks the personal touch of handwritten letters. C．Communication has evolved significantly over time, from letters to instant messaging. D．Virtual reality will play a major role in the future of communication. 【答案】1．B 2．C 3．A 4．B 5．C 【导语】本文是一篇说明文，文章主要讲述了通信方式从19世纪的手写信件到21世纪互联网和智能手机的即时通信的演变过程，以及这种演变对个人和商业的影响，同时展望了未来通信可能的发展方向。 1．细节理解题。根据文章第一段“The invention of the telegraph in the mid-1800s revolutionized communication, allowing messages to be sent over long distances in a matter of minutes.”可知，19世纪电报的发明使信息能在几分钟内传到很远的地方。故选B。 2．细节理解题。根据文章第二段“Social media platforms like Facebook, Twitter, and Weibo have further changed the way we communicate”和第四段“Today, email, video conferencing, and instant messaging have made it easier than ever to conduct business on a global scale.”可知，社交媒体平台、视频会议和即时通讯都被提及为现代通讯工具，而手写信件不属于现代通讯工具。故选C。 3．词句猜测题。根据文章第一段“In the 19th century, communication was a slow and laborious process.

Eating. Sleeping. Eating again. Life in a pigpen (猪圈) is boring. Nothing ever changes. Sometimes, I can’t help thinking: What do I live for? “Pigs produce pork. Just eat as much as you can!” my roommates told me. “It is sad, but you can’t change it, can you?” But last month, I heard the pigpen owner talking on the phone about something unusual. Some American doctors saved a very sick man by replacing his heart with a pig’s. This had never successfully been done before. My owner sounded excited. I know why. His elderly uncle had been in the hospital for weeks because of a serious heart problem. A heart transplant (移植), the doctors said, was perhaps the best choice for him. However, ___________. Most heart patients have to wait years before they are able to receive a transplant. Some of them die during this long and painful process. The successful operation (手术) in America means that in the future, people can depend on us pigs for healthy hearts. We are easy to raise, and we grow quickly. Sadly, I am just an ordinary pig. I’m not able to save my owner’s uncle. But some of my kids will probably be growing up in a special lab. They will be living as lifesavers, instead of pork providers. Perhaps my owner was talking to scientists about cooperation (合作) that day. Perhaps life in the pigpen will finally be a bit different. 1．Why was the owner so excited? A．Because he can cooperate with hospitals. B．Because he can get a good price for his pigs. C．Because one of his pigs can tell a true story. D．Because the new heart transplant may save his uncle. 2．Which of the following statements can be the best to put into ________. A．I can’t believe it at first B．that is really a great invention C．this is easier said than done D．the operation needs a lot of money 3．What is the purpose of Paragraph 3?

D．To tell readers the importance of the invention. 4．Who is probably able to save my owner’s uncle? A．I myself. B．My children. C．My owner. D．My roommates. 5．What is the passage mainly about? A．Pigs can produce nice pork. B．Pigs have something new to offer. C．The owner’s uncle has a heart problem. D．The mother pig hopes to meet bright future. 【答案】1．D 2．C 3．D 4．B 5．B 【导语】本文主要讲了猪圈里的一头猪发现主人因美国医生成功用猪心移植救人而兴奋，意识到未来猪可能成为人类心脏移植的来源，从而改变猪的命运。 1．细节理解题。根据“My owner sounded excited. I know why. His elderly uncle had been in the hospital for weeks because of a serious heart problem. A heart transplant (移植), the doctors said, was perhaps the best choice for him.”可知，猪的主人之所以兴奋，是因为他的叔叔患有严重的心脏病，而新的心脏移植技术可能拯救他叔叔的生命。故选D。 2．推理判断题。根据“the doctors said, was perhaps the best choice for him…Most heart patients have to wait years before they are able to receive a transplant. Some of them die during this long and painful process. ”可知，心脏移植是叔叔的最佳选择，但大多数心脏病人需要等待多年才能获得移植，有些甚至在此期间去世。因此心脏移植说起来容易但做起来难。故选C。 3．主旨大意题。本段通过对比传统心脏移植的困难（等待时间长、患者死亡风险）和猪心脏移植的优势（易饲养、生长快），说明了猪心移植这项发明的重要性。故选D。 4．推理判断题。根据最后一段“But some of my kids will probably be growing up in a special lab. They will be living as lifesavers, instead of pork providers.”可知，叙述者（猪）的孩子未来可能成为“救生员”（即提供移植心脏），而非肉猪。因此，能够救叔叔的可能是猪的孩子们。故选B。 5．主旨大意题。全文以猪的视角展开，先描述传统猪圈的枯燥生活，再通过“猪心脏移植”新闻引出猪的新价值——为人类提供移植器官，最后展望未来。因此，文章核心是“猪能提供新的贡献”。故选B。 On May 3rd, Yichang Police Station made history by firstly using a “robot police dog” in Hubei. Working with real police dogs, the robot police dog was sent to patrol (巡逻) and do something else. As a newcomer to the police station, the robot police dog interested many onlookers (旁观者).
