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. 1. When did the high-speed train Fuxing first run? A．In 2016. B．In 2017. C．In 2018. D．In 2019. 2. 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. 3. We can use Taobao for ________.

Passage 2 Every year, the National Youth Creativity Competition is held in China. It encourages teenagers to show their creative ideas and inventions. Last year, over 5,000 students from all over the country took part in it. One of the winners was 14-year-old Li Wei from Sichuan. His invention was a “smart” schoolbag. It has a GPS tracker (追踪器), so parents can know where their kids are. It also has a small fan that turns on when it’s hot, and a USB port to charge phones. Li Wei got the idea when he saw his little sister getting lost in a shopping mall. “I wanted to make something that can help keep kids safe and comfortable,” he said. Another winner was 16-year-old Zhang Mei from Shanghai. She invented a special chair for people with back pain. The chair can adjust (调整) its shape to fit the person’s back. Zhang Mei’s grandma had back pain for years, so she decided to create something to help her. These inventions show that teenagers have great creativity. They can use their ideas to solve real-life problems and make the world a better place. 1. What is the National Youth Creativity Competition for? A．Encouraging teenagers to create. B．Teaching teenagers to invent. C．Helping teenagers with studies. D．Giving prizes to smart students. 2. What does Li Wei’s schoolbag have? A．A GPS tracker and a fan. B．A USB port and a camera.

It can walk on land and swim in water. The robot has tubes (管子) as its legs. Air pushes the legs up and down, which makes it go forward. Scientists in the Netherlands made this robot. Now, they are trying to find new ways to better control it. In Shenzhen, a new robot cleaner has joined the city’s cleaning team. In just two hours, it can finish a job that takes four workers half a day to finish. It can move around on its own, safely avoiding people and cars as it cleans. The city’s cleaning work is quietly being handed over to robots. Meet Reachy MiniReachy Mini, a new desktop robot by Pollen Robotics, is on the market. It is 28 cm tall, 16 cm wide, and only weighs 1.5 kg. It can tell faces and voices, and even talk back to you. Designed as a learning tool, Reachy Mini comes with sensors (传感器), speakers and cameras.

Have you ever wondered why some ideas change the world while others disappear quickly? Scientists and thinkers have studied this question for a long time. They have discovered that powerful ideas share some common features. First, powerful ideas solve a real problem. Thomas Edison didn’t just invent the light bulb for fun. He wanted to solve the problem of darkness. Before the light bulb, people used candles and oil lamps, which were dangerous and gave little light. Edison’s idea met a real need, which is why it became so successful. Similarly, the Wright brothers built the first airplane because people wanted to travel faster and further. Second, powerful ideas come to life through hard work and persistence. Many inventors fail hundreds of times before they succeed. Edison famously said, “I have not failed. I’ve just found 10,000 ways that won’t work.” This shows that great ideas don’t come easily. The key is to keep trying and learn from each failure. Third, powerful ideas are shared with others. An idea that stays in someone’s mind can never change the world. That’s why inventors and thinkers often write books, give lectures, and work with teams to spread their ideas. For example, the Internet started as a small idea in one research lab but grew into a global system because thousands of people shared and developed it together. Fourth, powerful ideas often come from curiosity. People who are curious ask questions like “Why is this the way it is?” or “Is there a better way?” These questions open the door to new possibilities. Many of the most important inventions in history were created by curious people who never stopped asking questions. Finally, powerful ideas are often simple but profound. They don’t need to be complicated to be effective. The idea that everyone should be able to read and write, for example, has changed countless lives. 1. According to the passage, why did Thomas Edison invent the light bulb? A．Because he wanted to become famous. B．Because he wanted to solve the problem of darkness. C．Because he needed a new project. D．Because he wanted to prove he was smart. 2. What does Edison’s quote “I have not failed. I’ve just found 10,000 ways that won’t work.” teach us? A．Failure is shameful. B．Great ideas come easily. C．We should give up when things get hard. D．Failure is part of the learning process. 3. According to the passage, why is it important to share ideas? A．Because ideas can only change the world when shared. B．Because sharing ideas makes people famous. C．Because everyone should have the same ideas. D．Because it is easy to share ideas. 4. What does the underlined word “profound” in the last paragraph most probably mean? A．Simple and easy. B．Deep and meaningful. C．Long and complicated. D．Boring and useless. 5. What is the main purpose of this passage? A．To explain what makes an idea powerful. B．To describe different types of inventions. C．To compare famous inventors. D．To encourage people to become inventors. Passage 6 1. On December 26th, the Fuxing smart EMU (动车组) train C9309 left Yan’an Station, marking the opening of the Xi’an—Yan’an High-Speed Railway. This historic event means China’s high-speed rail network has now reached over 50,000 kilometers. This important milestone has reshaped (改变) the way people travel. Yan’an, a famous old revolutionary (革命性的) base, has now entered the high-speed rail age. 2. China’s high-speed rail network forms the backbone (骨架) of its “eight vertical (纵向) and eight horizontal (横向)” grid, connecting cities all over the country like a vast web—a closely connected transportation system. It has changed people’s lives significantly. Now, a distance of 500 kilometers can be covered in one or two hours, and 1,000 kilometers in about four. Even a 2,000-kilometer trip can be made in a single day. The ancient dream of “traveling a thousand miles in a day” has come true, bringing more convenient and efficient (高效的) travel to millions. Every day, high-speed trains can carry up to 16 million passengers—which is about the population of a megacity (特大城市). Currently, high-speed rail serves 97% of Chinese cities with over 500,000 people. 3. China’s high-speed rail success is known worldwide. It has the world’s longest network, longer than that of all other countries combined (联合的). From the Harmony to the Fuxing trains, China’s technology is now among the best. Foreign visitors often praise the trains as “very smooth” and “a wonder of technology.” High-speed rail does more than carry people—it drives regional (区域的) development, supports green travel, and brings people a better life. As China continues to invest in this network, we can expect even more exciting innovations (创新) and a brighter future for transportation. 1. In which sentence does “milestone” have the same meaning as the underlined “milestone”? A．The old milestone by the roadside means that London was 50 miles away. B．The invention of the printing press was a milestone in human history. C．I couldn’t help but skip to a few milestones. D．Starting school is a milestone for both children and parents. 2. What does the underlined phrase “eight vertical and eight horizontal grid” in Paragraph 2 refer to? A．A map of China’s revolutionary bases. B．The basic layout of China’s high-speed railway network. C．The schedule of high-speed trains. D．A plan for building megacities. 3. What is the main idea of the third paragraph? A．China’s high- speed rail has brought both economic and environmental benefits. B．China’s high- speed rail technology is inferior (差的) to other countries. C．Foreign visitors are not satisfied with China’s high-speed rail. D．China’s high- speed rail will soon be replaced by new technologies. 4. Why does the author mention foreign visitors’ praise? A．To suggest that foreigners like traveling in China more than locals do. B．To show that China’s high-speed rail technology is recognized globally. C．To criticize (批评) the high-speed rail systems of other countries. D．To encourage more foreigners to visit Yan’an. 5. The tone (语气) of the passage can best be described as ________. A．objective (客观的) and informative B．personal and subjective C．humorous and entertaining D．critical and negative (消极的) Passage 7 Pollution has caused too many problems for our planet. But luckily, science and technology offer powerful tools to reduce its harm. Let’s explore how modern science and technology help deal with pollution. Finding Pollution Some advanced sensors (高级传感器) can tell people where there is pollution in real time. Small machines in cities check air quality, detecting harmful gases like CO and SO2. Satellites from space show plastic waste in oceans and chemical leaks (泄漏) in rivers. These tools help scientists find pollution sources quickly. For example, when a factory leaks dirty water, alarms make loud sounds to tell environmental agencies (环保机构) within minutes. Cleaning Tools For Air Smog Towers: Big machines clean dirty air (about 1,000 classrooms of air every day). Electric Buses: No smoke! Quiet and clean. For Water Water Filters: Special nets in factories catch chemicals. Boat Robots: Boat robots collect plastic bottles. For Waste Recycling AI-powered machines sort waste automatically (自动地). Plastic bottles are turned into clothing or 3D-printer materials. Future Helpers Scientists are trying to test some new ideas. They are making different helpers for solving the problems such as tiny robots, Hungry Bacteria Eat and CO Catcher. Tiny robots are smaller than sand! They “eat” oil in oceans. Hungry Bacteria Eat “eats” harmful things in soil. CO Catcher can suck bad gases in the air. What can Students Do? Students can use apps like “EcoTracker” to report dirty places. They can also join school recycling clubs. Besides, they can take simple water filters to science class. Remember: Small actions + big technology = clean Earth! Let’s work together to help protect our environment and be greener people! 1. How do satellites help fight pollution? A．They help build smog towers. B．They make electric buses run. C．They catch chemicals in factories. D．They show plastic waste in oceans. 2. What is the main purpose of “Smog Towers”? A．To sort rubbish for recycling. B．To measure air quality in cities. C．To clean a large amount of dirty air. D．To collect plastic bottles in rivers. 3. What does the underlined word “suck” mean? A．take in B．cut down C．put away D．care for 4. How many measures are mentioned about fighting pollution for students in the last paragraph? A．Two. B．Three. C．Four. D．Five. 5. What’s the best title for the text? A．Where We can Find Pollution B．Some Tools for Reducing Pollution C．The Future of Science and Technology D．How Science and Technology Help Fight Pollution Passage 8 Today, food delivery (配送) is a big part of our lives. But did you know this idea started in China a very long time ago? About 1,400 years ago in the Tang Dynasty, there was a special delivery service for the emperor. He loved fresh lychees, a kind of fruit. To bring them to him fast, people used Yizhan (驿站) with fast horses and riders. There were many stops along the roads where riders could get a new horse. This way, the fruit could travel very quickly. Much later, during the Song Dynasty, delivery became popular for common people. A book from that time describes the busy city of Kaifeng. People often bought ready-made meals from shops. Without phones, they went to a restaurant or sent someone to order. Then, the restaurant would send the food to their homes by delivery workers. Cooks also used a special container (容器) called a wenpan to keep food hot. It was made of a two-layer (双层) china with a space in between for hot water. Nowadays, new technology has made delivery in China much faster and smarter. A great example is the use of drones (无人机) in Shenzhen. These flying machines can deliver medicine across the city in just minutes. This is part of the new “low-altitude economy,” which refers to economic activities carried out in low-altitude airspace. Drones also do other important jobs, like helping to put out fires or bringing life-saving tools to people during big sports events. A super-fast 5G-A network works like an air traffic control system, guiding these drones safely through the sky. All in all, from the wenpan to the 5G-A network, China’s delivery development shares a common goal: to meet people’s needs and make life better with creativity. 1. What was the Yizhan used for in the Tang Dynasty? A．Helping ordinary people deliver food quickly. B．Carrying fresh fruit for the emperor over long distances. C．Providing new horses for riders traveling on business. D．Creating many stops along the main roads for travelers. 2. How did people in the Song Dynasty order food without phones? A．By asking the cooks to send food by wenpan. B．By sending a message through a delivery person. C．By reading a book that described the restaurant. D．By going to the restaurant themselves or sending someone. 3. What can drones do according to the passage? ①Deliver medicine    ②Put out fires    ③Guide air traffic    ④Send life-saving tools A．①②③ B．①③④ C．①②④ D．②③④ 4. What is the correct time order of the following events? a. Deliver medicine with the help of 5G-A network. b. Use the Yizhan with fast horses to deliver lychees. c. People often bought ready-made meals from shops. d. Restaurants delivered ordered food to people’s homes A．b-c-d-a B．b-d-c-a C．c-b-d-a D．d-c-b-a 5. What does the passage mainly want to tell us? A．Tang Dynasty had the best delivery system for the emperor. B．The wenpan was a very important invention in the Song Dynasty. C．Long-term creativity is used to meet people’s needs and improve life. D．Drones are the most successful form of delivery in the modern China. Passage 9 The Drama Festival will run in and outside China from June 20th to July 7th. Sixty-five works will be put on both in theaters and online. “The festival is all about imagination connecting drama with the latest technology,” says Liu Chang, the manager of the festival, who is also a drama director. Technology has improved design, performances and so on. Artists like Liu aren’t sure if the new technology can take drama to the future. A Chinese play directed by Meng Jinghui, inspired (被赋予灵感) by the two-part drama Faust by Johann Wolfgang von Goethe, will be on as the opening play of the festival. In the first half of the play, Meng introduces the story to 400 real audiences (观众) sitting in the Fengchao Theater in Beijing. The second half of the play will have more audiences, who use their cellphones, computers and headsets to be part of the play online. Zhang Zhouxiang is a director full of imagination. His work, inspired by Hieronymus Bosch’s painting The Garden of Earthly Delights, will be shown from June 30th to July 2nd. Supported by AI, audiences can explore the fictitious scene, similar to the feeling in the real world, as the painting describes. “The stage design is done by AI, which is like an assistant (助手) realizing the ideas of me and my team,” says Liu. “Now I try to use the latest technology, such as ChatGPT, to write the script (剧本), and I am still working on it because the language model is difficult to understand.” Now, technology is playing a more and more important role. Many artists want to use it to improve drama. They are very interested in the relationship between people and the latest technology, especially when connected in drama — a scene to dream. 1. When will the Drama Festival run? A．From June 7th to July 20th. B．From June 30th to July 30th. C．From June 20th to July 7th. D．From June 30th to July 2nd. 2. Which of the following is TRUE according to this passage? A．Liu has managed to write the script by ChatGPT. B．Audiences can explore the scene of Liu’s work by AI. C．Meng’s two-part drama Faust will be on at the opening. D．Liu doubts whether technology can greatly improve drama. 3. What does the underlined word “fictitious” mean in Paragraph 3? A．Historical. B．Imaginary. C．Scientific. D．Real. 4. What is the structure of this passage? (①=Paragraph 1...) A． B． C． D． 5. What is the main purpose of the passage? A．To show the connection between technology and drama. B．To advertise the plays in the Drama Festival. C．To explain why drama needs the latest technology. D．To encourage more audiences to watch dramas online. Passage 10 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! 根据材料内容选择最佳答案。 1. What is the team’s purpose in inventing the device? A．To test brain waves. B．To warn of a health risk. C．To help disabled people read. D．To read books for the elderly. 2. What can we learn from Paragraph 4? A．How the device worked. B．Who invented the device. C．What kind of books Qi read. D．Why the special event took place. 3. What’s the best sentence for “ ▲ ” in Paragraph 5? A．The inventors got a prize. B．The invention was easy to buy. C．But the team was not happy about it. D．But not everyone was on the same page. 4. What is one of the problems of the device? A．It reads too fast. B．It is too expensive. C．It can’t go backwards. D．It can’t record how often a reader blinks. 5. What does the writer think of the future of the device? A．Bright. B．Uncertain. C．Worrying. D．Meaningless. Passage 11 Imagine this: a car driving through busy city traffic, but with no one in the driver’s seat. This is no longer just an idea. In cities like Wuhan and Foshan, self-driving cars are already on the road. They are being tested and used in real life. But as they appear, an important question comes to mind: are they truly ready for everyone to use? Unlike traditional cars with a driver, these cars use cameras and sensors (传感器) as their “eyes”, with a powerful computer as the “brain” to make decisions. ________ For example, one big company reports that its self-driving cars have had far fewer accidents than cars that are driven by people. However, problems still happen. A short video of a robotaxi hitting a car in Wuhan made many people worried about safety. Sometimes, these taxis can also act strangely, like suddenly breaking down on the road, which might obstruct traffic. Also, some taxi drivers are unhappy. They feel that these cheap robotaxis, which often offer much lower price, are taking away their customers. Others are afraid of being replaced by this new invention. At the same time, right now, most robotaxi companies are not making money. But they believe that as technology gets cheaper and more people use the service, they will become profitable (盈利的) in a few years. Clearly, self-driving cars have a promising future. They are arriving, but some problems must be solved before they become common in our daily lives. 1. How does the writer begin the passage? A．By telling a moving story. B．By describing a clear picture. C．By giving a surprising number. D．By comparing two different ideas. 2. Which of the following can be put in “________” in Paragraph 2? A．They are becoming even cheaper. B．Their aim is to replace taxis. C．Safety is their biggest advantage. D．People trust them completely. 3. What does the underlined word “obstruct” in Paragraph 3 mean? A．Stop. B．Guide. C．Control. D．Improve. 4. What makes taxi drivers feel unhappy? A．Fewer new taxis. B．Stricter rules. C．Stronger competition. D．More traffic jams. 5. Which is the best title for the passage? A．Cars with a Robot Brain B．Taxi Drivers’ Unhappy Days C．Self-Driving Cars on the Road D．Self-Driving Cars: Ready or Not Passage 12 Making it more real Hologram technology has made a big breakthrough 把照片变成立体人？全息影像让科幻成为现实 Imagine you’re in a sci-fi (科幻小说) world, and you video-call your friend. You might see them in a three-dimensional (3D) way – or in holograms (全息影像). Although this isn’t possible in real life yet, researchers recently made holograms easier to create, said a new study. To take a 3D photo of a person, most hologram technologies need special cameras. They record how the person looks from different angles (角度) under different lights. This information makes the hologram look lifelike. However, holograms can’t be widely used because they are difficult to make. The researchers from Chiba University in Japan made a new computer program. It can turn normal pictures we take into 3D holograms. Their program used a technology called deep neural networks (深度神经网络). First, it receives information from an image taken by a normal camera. It then predicts (预测) the depth (深度) of things in the image. For example, in a 3D photo, the background should be deeper than the person. With all the information, the program creates a 3D hologram. But it can look strange at first. The program will then check the hologram to fix problems and make it look more real. The program can be used to create holograms in VR headsets (头显设备). For example, a user sends a picture, and the other user can see the “real” look of it in 3D．If it’s used in cars, drivers can see information, such as road signs, in 3D．This makes it easier for the drivers to see and thus makes sure that they won’t miss important information. In the future, when holograms become more common, they can also help doctors. Medical students can learn quickly by looking at 3D images of the human body, and doctors can better understand a patient’s illness.   Choose the answer: 1. What does the new program make use of to create a hologram? A．A normal picture. B．A special camera. C．Recordings from different angles. D．Recordings under different lights. 2. Compared to the traditional technologies, the new program is ________. A．easier B．more expensive C．more natural D．more predictable 3. In what order does the new program work?    a. Predict the depth of things in the photo. b. Put out the final 3D hologram. c. Receive a normal photo. d. Put out an imperfect 3D hologram. e. Process the 3D hologram again. A．abcde B．acdeb C．cadeb D．cabed 4. How might holograms in cars benefit drivers? A．They make driving more enjoyable. B．Drivers will find road information easily. C．They will help predict dangers and traffic. D．Drivers needn’t mind the cars behind. 5. What does the last paragraph tell us? A．Holograms might be used in medical fields. B．Patients won’t suffer during treatment with holograms. C．We can live in a 3D world earlier than expected. D．Doctors won’t make mistakes anymore with holograms. 6 / 14乐思英语 学科网（北京）股份有限公司 $单元话题精练 专题J906（说明文）单元话题 题型梯度特训（新教材人教版） Unit 6 Beyond Earth 学校:___________姓名：___________班级：___________考号：___________ 内 容 提 要 一、 初阶练手 Passage 1 – 6 二、 进阶提升 Passage 7 -12 Passage 1 Since the beginning of human history, people have looked up at the stars and wondered what they were like. Many ancient cultures believed that these points of light were from gods or other mysterious worlds. However, as technology and science developed, we learnt the truth about stars. They are real places like our own sun, and they are further away than anyone imagined. The man-made object which has travelled furthest from Earth is Voyager 1. This spacecraft was launched in 1977. A special record with Earth’s sounds and pictures is carried on board, in case alien life finds it. It is 23.5 billion kilometres away from Earth now, but still far from the nearest star Proxima Centauri (4.2 light years away). Human space travel faces huge challenges. A trip to Mars takes 6–9 months. Visiting other stars would take hundreds of thousands of years. But scientists do not give up. They plan longer sleep trips and faster spacecraft. With global cooperation, we may reach stars one day. 根据短文内容，选择最佳答案。 1. What did ancient people think stars were? A．Other suns far away. B．Lights from gods and mysterious worlds.

It includes space, all the matter and energy in space, and even time. The stars like the Sun and planets like Earth are part of it. These planets go around the Sun, which is just one star among billions. The Moon is not a planet. It circles Earth and is also part of this huge system. Scientists say the solar system is about 4.6 billion years old. They found this by studying rocks and small space stones. Earth seems permanent, but it’s not. The Sun, much bigger than Earth, will change too, possibly growing large enough to take in nearby planets like Earth one day. The universe is about 13.8 billion years old. Scientists found this by looking at old stars and how fast the universe is getting bigger. ________ This surprises scientists, because they expected gravity to slow the stars down. Earth and humans are very young compared to the universe. Life on Earth has been around for 3.8 billion years, but humans have only been here for about 300,000 years. That’s a tiny bit of time—like a second in a whole year! We’ve explored only our own solar system, and even then, we haven’t seen all the planets and moons. With new technology and curiosity, we keep learning about the universe. How did the universe begin? Are there other planets with life? Though space is big and full of secrets, each discovery helps us understand our place in it. The more we learn, the more we want to explore. 根据材料内容选择最佳答案。 1. What is the Moon according to the passage? A．A planet that goes around the Sun. B．A star like the Sun in the universe. C．A body that circles around Earth. D．A form of energy in space. 2.

D 【导语】本文主要介绍了宇宙的组成、太阳系的年龄、地球和人类的起源以及科学家对宇宙的探索。 【详解】1. 根据第一段“The Moon is not a planet. It circles Earth and is also part of this huge system.”可知，月球是围绕地球运转的天体。 2. 根据第二段“The Sun, much bigger than Earth, will change too, possibly growing large enough to take in nearby planets like Earth one day.”可知，太阳也会改变，它可能会吞噬像地球这样的邻近行星；结合前文“Earth seems permanent, but it’s not.”可推知，此处应表示地球看似永恒，但事实并非如此。因此permanent在此处的意思是endless“永恒的、无尽的”。 3. 根据第三段“This surprises scientists, because they expected gravity to slow the stars down.”可知，科学家原本预计引力会减慢恒星的速度。由此推知，空缺处应填入与恒星的速度相关的内容，A项“离我们很远的大多数恒星移动的速度越来越快。”符合语境。 4. 根据第二段“Scientists say the solar system is about 4.6 billion years old.”，第三段“The universe is about 13.8 billion years old.”以及第四段“Life on Earth has been around for 3.8 billion years, but humans have only been here for about 300,000 years.”可知，正确的时间线是：宇宙→太阳系→地球上的生命→人类。 5. 根据全文内容，文章不仅介绍了宇宙的组成和年龄，还讨论了地球、人类以及科学家对宇宙的探索，强调了人类在宇宙中的位置，因此选项D“宇宙和我们在其中的位置”是最佳标题。 Passage 7 阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳答案。 The Mystery of the Universe Have you ever looked up at the night sky and wondered what is out there? For thousands of years, humans have been curious about the universe. This curiosity has driven us to explore the unknown, leading to some of the greatest discoveries in history. Why Do We Explore? There are several reasons why humans explore space. First, exploring space helps us understand the origin of the universe and our place in it. By studying stars, planets, and galaxies, we learn about the history of the universe and how it was formed. Second, space exploration leads to new technologies that improve our daily lives. Many inventions we use today, such as memory foam and LED lighting, were originally developed for space programs. Third, space exploration inspires us. When we see astronauts in space or rovers on Mars, we are reminded that humans are capable of amazing things. The Role of Curiosity Curiosity is perhaps the most important driver of space exploration. This curiosity is what makes us human—the desire to know what is beyond the horizon and in the stars. Every great discovery in history has been driven by curiosity. Without it, we would never have landed on the moon or sent rovers to Mars. What Does the Future Hold? In the future, more advanced telescopes will be developed to observe distant galaxies. New spacecraft will be built to carry astronauts further into space. It is hoped that one day, human beings will set foot on Mars. The possibilities are endless, and the journey has only just begun. 1.

While Dongfanghong-1 is China’s first small step in space, Shenzhou-20 now can carry astronauts and perform scientific tests, showing China’s great steps forward. As one of the key advances (进步) of this mission, the Long March-2F rocket has made 32 technical improvements. One of them is the telemetry system (遥测系统). In the past, scientists stored important information in a “black box” (a special recorder) and studied it after its return. But now, the new system collects it by using cameras and sensors (传感器) on the tower in some key locations. With a transmission rate (传输率) of 5 Mbps, it can send around 100 A4sized pages of documents (文件) every second. This allows flight information to be collected and sent back to Earth in real time during the whole mission. Later, China plans to carry out more manned missions and supply missions. If these are achieved, the space station will be able to run over 180 science programs including life science and other fields. At the same time, China is working toward landing astronauts on the moon before 2030. And new rockets and spaceships are being tested to make sure they are safe. All these steps show China’s dream to reach deep space and share knowledge with the world. China’s space journey grows more promising every day. Each mission shows not just scientific achievements but also the realization of a centuriesold dream. 1. How does the writer show China’s progress in space in Paragraph 1? A．By comparing facts.

Space scientists have been greatly inspired (赋予灵感) by the old stories and ancient famous people when giving them names. Since thousands of years ago, Chinese people have dreamed of going to the moon. Chang’e Flies to the Moon is one of the most popular stories. As you can see , China’s first man-made satellite to circle around the moon was named Chang’e I. More interestingly, the moon rover (巡视器) was named after the Jade Rabbit, who is the partner of Chang’e in the story. These old stories carry people’s best wishes and dreams. With the development of science and technology, our scientists have made them come true. Kua Fu Runs After the Sun is another story to show how much ancient Chinese people wanted to know about the unknown world. Now, Kua Fu is going with the scientists to “visit” the sun, because we have a space project called Kua Fu Mission. Besides the ancient stories, space scientists also get ideas from ancient famous people. For example, Mozi, an ancient scientist, discovered that light travels in a straight line over 2,000 years ago. His discovery made space study take a big step at that time. So, China’s first quantum (量子) science satellite was named Mozi, making China the first country in the world to achieve quantum communication between satellites and the ground. From such simple things as giving names to the satellites , we can see how great our traditional culture is and what influence it has on our modern science and technology. 1. In China , space scientists get ideas from ________  when naming satellites. ①old stories   ②traditional projects    ③ancient famous people     ④popular inventions A．①② B．①③ C．②④ D．①④ 2.

We use “lunar bricks”, of course! Scientists at Huazhong University of Science and Technology (HUST) have developed “lunar bricks”. They hope to use the bricks to build a research station on the moon. To make the bricks, the scientists used a lunar soil simulant (模拟月壤). The bricks are more than three times stronger than normal red bricks. They also have special structures, which were used in ancient Chinese buildings. This makes it possible to simply put these bricks together. Professor Zhou Cheng from HUST said that they had tested five different kinds of simulated lunar soil composition (成分) and used three ways to harden them. In this way they could choose the best materials for making the bricks. “Lunar soil isn’t the same everywhere on the moon,” Zhou said. “For example, one of the kinds tested simulates the lunar soil at the landing site of Chang’e-5, which is mainly basalt (玄武岩).” The lunar bricks need to be tested well before being used because the moon has an extreme (极端的) environment. Quakes often happen there. And it gets as hot as 180 ℃ during the day and as cold as -190 ℃ at night. The lunar bricks have been sent to China’s space station on the “Tianzhou-8” spacecraft. There, scientists carried out tests to see how well the bricks work in space. The first bricks returned to Earth on November 14th, 2025. 1. Which properly shows the strength comparison of lunar bricks and red bricks? A． B． C． D． 2. How did scientists find the best materials for making lunar bricks? A．They learned about lunar soil from scientific reports. B．They compared different bricks used widely nowadays. C．They read many books about ancient Chinese buildings. D．They did many tests on simulated lunar soil and treated it in different ways. 3. What is the main idea of the fourth paragraph? A．The introduction of China’s “Tianzhou-8” spacecraft. B．The reasons why lunar bricks need to be tested in space. C．The temperature difference on the moon between day and night. D．The time when the first lunar bricks returned to Earth. 4. Which of the following best explains the purpose of developing “lunar bricks” according to Paragraph 1? A．To study the composition of lunar soil. B．To build a research station on the moon. C．To test the technology of making bricks in space. D．To improve the strength of normal red bricks. 5. What is most probably the structure of the passage? A． B． C． D． 【答案】1. D 2. D 3. B 4. B 5.

For many kids, staring at the stars leads to daydreams about what it would be like to be an astronaut. Just think about how amazing it would be to set foot on the moon or another planet! Although it sounds like it would be great fun to travel to outer space, it would be a lot of work too. Travelling to outer space needs lots and lots of preparation. Once you are in space, nothing can come on board the spaceship and nothing can go out. You must take all you need into outer space to keep yourself alive. Let’s call these things “inputs”, including food, water and oxygen. Every input creates an output. If you open a box of cookies for breakfast, what will you do with the box when it’s empty? Every piece of rubbish you create in space will remain on the ship with you. Your body will also output food and water. Since nothing can leave the spaceship, you will have to think of another way to deal with these bodily wastes. Even breathing creates an output: carbon dioxide (二氧化碳)! It’s true that plants depend on carbon dioxide in the same way humans depend on oxygen to breathe. However, plants have other input needs. If you take a banana tree with you, you will need to bring enough water to keep it alive. You must also consider another type of output rubbish in the ship after taking the fruit as snacks—the banana peel. See how carefully you have to plan for a trip to outer space? How can you plan your actions on Earth to have the least influence on the environment and your future? Not only do you have to think about all the things you’ll need, you will also have to consider the influence of those things because of the wastes they may create. 1. What can we learn from the first two paragraphs? A．It’s challenging to travel in space. B．It’s boring to live on the moon. C．It’s relaxing to stare at the stars. D．It’s difficult to be an astronaut. 2. What do we know about the input in space? A．It will make astronauts sleepy. B．It only means things to eat and drink. C．It is quite important to astronauts. D．It can help astronauts deal with rubbish. 3. Which of the following is an “output” according to Paragraph 3? A．Some cookies. B．Food and water. C．Your oxygen mask . D．The empty cookie box. 4. What does Paragraph 4 mainly talk about? A．The reason why breathing creates an output. B．A way to plant a banana tree in space successfully. C．The reason why plants depend on carbon dioxide D．A way to deal with carbon dioxide in the spaceship. 5. What is the best title for the passage? A．How to Prepare for a Trip to Outer Space B．How to Deal with Wastes in the Spaceship C．Differences Between Inputs and Outputs D．Different Ways to Deal with Wastes in Space 【答案】1. A 2. C 3. D 4. D 5. A 【导语】本文介绍太空旅行需要极其周密的计划。 【详解】1. 第一段讲到太空旅行听起来很棒，第二段说“it would be a lot of work too. Travelling to outer space needs lots and lots of preparation.”，说明太空旅行具有挑战性。 2. 第三段提到“You must take all you need into outer space to keep yourself alive... including food, water and oxygen.”，说明“input” (输入) 对宇航员非常重要。 3. 第三段提到“If you open a box of cookies for breakfast, what will you do with the box when it’s empty? Every piece of rubbish you create in space will remain on the ship with you.”，所以空的饼干盒是“output” (输出/废物)。 4. 第四段讨论了呼吸产生的二氧化碳以及如何处理香蕉树带来的各种需求 (水) 和废物 (香蕉皮)，说明本段讲的是如何处理飞船中的二氧化碳。 5. 全文围绕太空旅行需要准备“输入”和处理“输出”废物展开，强调周密计划的重要性，所以最佳标题是“如何为太空旅行做准备”，选项A正确。B“如何处理飞船中的废物”只是部分内容；C“输入和输出的区别”不完整；D“在太空中处理废物的不同方式”也是部分内容。 Passage 12 So far, China has successfully sent a large number of satellites (卫星) and spaceships into space. Space scientists have been greatly inspired (赋予灵感) by the old stories and ancient famous people when giving them names. Since thousands of years ago, Chinese people have dreamed of going to the moon. Chang’e Flies to the Moon is one of the most popular stories. As you can see, China’s first man-made satellite to circle around the moon was named Chang’e I. More interestingly, the moon rover (巡视器) was named after the Jade Rabbit, who is the partner of Chang’e in the story. These old stories carry people’s best wishes and dreams. With the development of science and technology, our scientists have made them come true. Kuafu Runs After the Sun is another story to show how much ancient Chinese people wanted to know about the unknown world. Now, Kuafu is going with the scientists to “visit” the sun, because we have a space project called Kuafu Mission. Besides the ancient stories, space scientists also get ideas from ancient famous people. For example, Mozi, an ancient scientist, discovered that light travels in a straight line over 2,000 years ago. His discovery made space study take a big step at that time. So, China’s first quantum (量子) science satellite was named Mozi, making China the first country in the world to achieve quantum communication between satellites and the ground. From such simple things as giving names to the satellites, we can see how great our traditional culture is and what influence it has on our modern science and technology. 1. What does the underlined word “them” in Paragraph 1 refer to? A．Space scientists. B．Satellites and spaceships. C．Public wishes for space exploration. D．Old stories and ancient famous people. 2. What do we know about Chang’e I according to the passage? A．It is China’s first man-made satellite. B．It carried the Jade Rabbit to the moon directly. C．It is named after the story Chang’e Flies to the Moon. D．It was the first satellite to communicate with the ground. 3. Why did the writer mention Mozi in the passage? A．To show Mozi was the greatest scientist in ancient China. B．To explain how China developed quantum communication. C．To prove ancient scientists knew more about space than modern ones. D．To give an example of naming a satellite after an ancient famous person. 4. What can we infer from the passage? A．All Chinese satellites are named after ancient stories or people. B．Ancient Chinese stories are more important than modern science. C．Naming satellites after ancient culture can make them work better. D．China’s traditional culture plays an important role in modern space technology. 5. What is the best structure of the passage? A．①②③④/⑤ B．①②③/④/⑤ C．①/②③④/⑤ D．①/②/③④/⑤ 【答案】1. B 2. C 3. D 4. D 5. C 【导语】本文是一篇说明文，主要介绍了中国航天器以古代故事和人物命名的文化传统及其意义。 【详解】1. 由第一段“Space scientists have been greatly inspired…when giving them names”可知，太空科学家在给“它们”命名时受到了启发。结合前一句“China has successfully sent a large number of satellites and spaceships into space”可知，科学家是给发射入太空的“卫星和宇宙飞船”命名，因此，“them”指代前文的“satellites and spaceships”（卫星和飞船）。 2. 由第二段“China’s first man-made satellite to circle around the moon was named Chang’e I”及“named after the Jade Rabbit…old stories carry people‘s best wishes”可知，嫦娥一号以“嫦娥奔月”的故事命名。 3. 由第四段“Besides the ancient stories, space scientists also get ideas from ancient famous people”及“China’s first quantum science satellite was named Mozi”可知，作者提到墨子是为了举例说明以古代名人命名卫星的做法。 4. 由最后一段“we can see how great our traditional culture is and what influence it has on our modern science and technology”可知，中国传统文化对现代航天科技有着重要影响。 5. 文章结构为：第一段引出话题；第二、三、四段分别举例说明以古代故事和人物命名航天器；第五段总结。 21 / 21乐思英语 学科网（北京）股份有限公司 $
