Wait a second, take a closer look at that blue one. It is actually a robot! This scene happened at an event, the World Digital Education Conference, from May 14th to 16th in Wuhan, Hubei province. Besides blue ones, there were red and yellow robotic fish, too. It is scientists at Wuhan University who have made them. At the length of about 53 centimeters, the fish were very lifelike. The joints (关节) in their heads and tails were made in a special way to let the fish move fast and easily. This is thanks to bionic engineering (仿生工程), which brings together nature and man-made things. “I love to see the bionic fish,” Professor James Crabbe from Oxford University told Jiupai News, “It could tell us much more about fish swarming and how fish behave (表现).” In fact, swarming in fish means they swim together in large groups. It helps them stay safe, find food and save energy (能量). Learning about swarming helps us understand how fish live and how changes in the environment matter to them. As for the pretty colors of the bionic fish, they come from the LED lights on their bodies, said People’s Daily. These lights can also make shadows, giving the underwater world a party feel. Even better, the bionic fish are smart. With the help of AI and sensors (传感器), they can “see” things in their way and learn to avoid them, said Changjiang Daily.

This amazing work brings hope to many people. The AI Baby volunteer team was started by Sheng Jianzhong, a student at Huazhong University of Science and Technology in Wuhan. Sheng studies digital image processing (数字图像处理). One day, when he watched TV, he saw blurry photos of missing children. He thought, “We need clearer pictures to help these kids and their families.” So, he called his classmates and formed a team. They wanted to use AI to make a difference. After six months of hard work, the team made an AI program. This program can turn blurry photos into clear ones. These clear photos are then shared online and offline. Thanks to their efforts, 19 children who were abducted (被拐) have returned home. And they have given hope to over 1,000 families by restoring photos of their missing relatives. Sheng said, “We call it ‘restoration’, but actually, these photos are made by AI. They look so much like the real ones that it’s hard to tell the difference!” One of their most famous cases was helping find Sun Zhuo, who was taken away in 2007. The only clue was a blurry picture of the kidnapper (拐卖者) from a camera. The AI team helped the police identify (确定) the criminal. Finally, in 2021, Sun Zhuo and his father met again. Volunteers from Taiwan also joined this meaningful work. Yen Hsu-hui, who was born in Taiwan, joined the team almost a year ago. His mother works in elderly care in Taiwan. She often talks to old people who came from the Chinese mainland. Yen said, “Some of these old people find their families on the mainland, but others die without seeing their loved ones again.” Yen tells people in Taiwan about this AI way to find lost relatives. Chang Shao-lin, a 20-year-old volunteer from Taiwan, said, “I became a volunteer because I want more people to find their families, just like I did.” This team’s work shows how technology and kindness can help make the world a warmer place. 1．How did the AI Baby volunteer team help the police find Sun Zhuo? A．By talking to the criminal directly. B．By making a blurry picture of the criminal clear with AI. C．By asking volunteers in Taiwan for help.

To be honest, they use digital technology too much. They are losing their skills to do simple things. They can’t make toys themselves with hands or help Mom cook dinner. And worst of all, they seem to be losing interest in communicating with others. “I have talked with a number of teachers. They care about the rising numbers of young pupils who can play with computers or smart phones, but have few or no skills to make things,” said a teacher, Colin Kinney. “Many pupils can’t communicate with other pupils, but their parents are glad to see the skills of their children to use a computer or a smart phone.” Instead of playing with other children, more and more children are choosing to stay indoors and quietly play with a tablet (平板电脑) on weekends and after school. How can a child grow up to be a very good artist unless he learns how to use a paintbrush and develop his painting skill? How can a child learn to make friends as he gets older unless he learns to communicate with others at a young age? Digital technology can be used for good or bad. We can use a stone to either break a window or build a house. We shouldn’t blame the children. We should help them make right choices. It is certainly necessary for children to know how to use digital technology in today’s world, but what is more important is that we should encourage them to develop social abilities (社交能力) which are good when they grow up. 1．What’s the worst problem in the first paragraph? A．Children can’t make things themselves. B．Children make too many friends online. C．Children don’t want to communicate with others. D．Children don’t like helping Mom cook meals at home. 2．According to Colin Kinney, which of the following is TRUE? A．Teachers don’t notice that young pupils have few skills to make things. B．Many parents are very happy that their kids can use digital technology. C．Many teachers don’t care if young pupils can play with computers or tablets. D．Some parents are worried that their kids use digital technology too much. 3．What does the underlined word “blame” mean in Chinese? A．表扬 B．原谅 C．评价 D．责怪 4．The passage is probably a ________. A．notice B．story C．diary D．report 5．What does the writer mainly want to tell us? A．It’s very important for children to have social skills. B．It’s very helpful for children to do some housework. C．It’s necessary for parents to learn to use digital technology. D．It’s difficult for teachers to make right choices for the pupils. 【答案】1．C 2．B 3．D 4．D 5．A 【导语】本文指出当下孩子过度沉溺数字技术，致使动手和社交能力受损，教师和家长对此持不同态度，作者认为数字技术利弊兼具，不应责怪孩子，而应助力其做出正确选择，着重培养社交能力。 1．细节理解题。根据第一段“And worst of all, they seem to be losing interest in communicating with others.”可知，最糟糕的问题是孩子们似乎对与他人交流失去兴趣。故选C。 2．细节理解题题。根据“Many pupils can’t communicate with other pupils, but their parents are glad to see the skills of their children to use a computer or a smart phone.”可知，许多家长高兴于孩子使用电脑或智能手机的技能。故选B。 3．词句猜测题。根据“Digital technology can be used for good or bad. We can use a stone to either break a window or build a house. ”和“We should help them make right choices.”可知，数字技术有利有弊，应该帮助孩子们正确利用数字技术，而不应该对孩子们进行负面的评判，“blame”意为“责怪”。故选D。 4．推理判断题。通读全文内容可知，文章围绕孩子过度使用数字技术这一现象展开，分析现状、各方看法并提出观点，具有一定的调查分析性质，更像是一篇报告。故选D。 5．主旨大意题。根据“but what is more important is that we should encourage them to develop social abilities which are good when they grow up”可知，作者主要想告诉我们鼓励孩子培养社交能力很重要。故选A。 进阶拓展训练5篇 Now in countries like the USA, more and more children seem to get lost in a “sea of digital technology (数字技术)”.

I ignored her, of course. Fast-forward a few decades and now I’m the parent. My 5-year-old lives in a world where screens aren’t fixed pieces of furniture. You can’t even avoid them by going outside. Screens are not only in our pockets. They’re everywhere. The concerns have grown with the screens. In the past decade, we have heard that they will damage our mental health. Many of us feel more distracted by them, feeling guiltier and more tired as a result. The apps and websites we can access on our phones have also sparked widespread concern. Big tech companies are also good at making use of our need for social recognition, hooking us on likes, retweets and follower counts. Social media has created a culture of mass narcissism (自恋), which has led many to worry about the emotional stresses on teenagers. A quick online search brings up dozens of papers linking screen use or social media with harmful effects on mental health, including depression and suicide. Such statements are alarming. They are also widely believed, thanks to popular books like iGen by Jean Twenge, which claims that digital technology has ruined a generation. Yet, Amy Orben at the University of Oxford, who studies the impact of digital technology and social media in particular on mental health, holds different views. She claims that the underlying data can be used to tell different stories. She also spotted shortcomings in several large studies that claimed to show correlations (相关性) between the use of devices with screens and depression in users. Twenge stands by her own findings, pointing in turn to what she considers flaws in Orben’s research methods. For David Max, at Royal College of Child Health in London, the effect of screen time and social media use on mental health remains speculative. “We cannot regard social media overall as good or bad,” says David. “We don’t know whether in individual cases social media is not responsible,” he says. The explosion of mobile phone use has revolutionized our lives. I can download movies, write articles, communicate with my family and broadcast to the world all at the push of a button. Rather than impose constraints (限制), we should take a look at our use of screens and ask how they fit with the activities and lifestyle. Every new technology with widespread impact has given rise to new fears. So the best bet may simply be to ask yourself what level of screen use makes you and those around you happy and try to stick to it. If you find yourself overly addictive, don’t panic—and certainly don’t feel guilty. Nobody knows anything worth getting scared about. 1．According to the passage, people give likes, retweet or count followers to ________. A．share one’s lifestyles B．show respect for others C．seek social recognition D．relieve emotional stresses 2．The underlined word “speculative” probably means “________”. A．doubtful B．specific C．important D．abstract 3．What can be learned from the passage? A．Teenagers are more affected by screen use both physically and mentally. B．Orben claims it is far too early to blame screen use for ruining a generation. C．Big tech companies help to produce many research papers on mental health. D．Twenge mainly introduces the overall benefits of digital technology in her books. 4．The passage is written to ________. A．encourage readers to reduce the time of screen use B．share different opinions on the effects of screen use C．explain why screen use may have negative effects on people D．relieve people’s concerns and worries about the use of screens 【答案】1．C 2．A 3．B 4．D 【导语】本文是一篇说明文，主要介绍了屏幕使用对心理健康的影响，特别是社交媒体的影响，并缓解人们对屏幕使用的担忧。 1．细节理解题。根据“Big tech companies are also good at making use of our need for social recognition, hooking us on likes, retweets and follower counts.”可知，人们点赞和计算粉丝数是为了寻求社会认同。故选C。 2．词句猜测题。根据“We cannot regard social media overall as good or bad,”和“Rather than impose constraints (限制), we should take a look at our use of screens and ask how they fit with the activities and lifestyle.”可知，目前对于屏幕时间和社交媒体使用对心理健康的影响仍是有疑问的，所以speculative在此处指的是“值得怀疑的”。故选A。 3．推理判断题。根据“which claims that digital technology has ruined a generation. Yet, Amy Orben at the University of Oxford, who studies the impact of digital technology and social media in particular on mental health, holds different views. She claims that the underlying data can be used to tell different stories.”可知，Orben认为目前的数据不足以证明屏幕使用对一代人造成了伤害。故选B。 4．主旨大意题。根据“Every new technology with widespread impact has given rise to new fears. So the best bet may simply be to ask yourself what level of screen use makes you and those around you happy and try to stick to it. If you find yourself overly addictive, don’t panic-and certainly don’t feel guilty. Nobody knows anything worth getting scared about.”可知，每一项具有广泛影响力的新技术都引发了新的担忧。所以，最好的方法可能就是问问自己，什么程度的屏幕使用会让你和周围的人感到快乐，并努力坚持下去。如果你发现自己无法停止，不要焦虑，当然也不要感到内疚。没有人知道有什么值得害怕的。所以这篇文章的目的是缓解人们对屏幕使用的担忧。故选D。 Nowadays, more and more people like to watch short videos.

With the help of digital technology (技术), villagers are living an easier and happier life. Farming in the past was not an easy job. Farmers worked hard all year round. At the same time, they usually found it difficult to solve problems like plant diseases and pest (害虫). Now, there have been big changes in farming. For example, in Dayi County, Sichuan Province, AI machines help local farmers know when and how to fertilize (施肥) and kill pests. In this way, they make farmers work more easily with less time and energy. Thanks to the Internet, a new business called rural e-commerce (乡村电子商务) grows. Selling fresh fruit and vegetables to cities is faster. The business also helps villagers live a digital life. They can get many things done on different kinds of apps. They can also use drones to help with their farm work. More visitors travel in beautiful villages because of digital technology. A good example is Huacheng Town, Guangdong Province. Visitors can know where to park their cars for free, when to book a ticket easily and what to buy online. They can also enjoy the view of nearly every part of the town by using VR. 1．According to Paragraph 2, we know AI machines can help farmers ________. A．water the crops B．harvest the crops C．know when and where to fertilize D．save time and energy on farming 2．What is the structure of this passage? (①= Paragraph 1, ②= Paragraph 2...)

While some find joy in these changes, others face difficulties. Many seniors are discovering fun ways to use technology. Free online classes let them learn painting, gardening, or even how to use smartphones. For example, 72-year-old Grandma Zhang recently learned to make digital (数字的) birthday cards for her grandchildren. Video apps like WeChat help families stay connected. “I see my grandson’s face every day though he studies abroad,” said Mr. Li, 68, with a smile. Smartwatches are also popular—they check heart rates and remind users to take medicine. Some hospitals even let patients talk to doctors online, saving time for those who have trouble walking. However, not everything is easy. About 40% of people over 65 say technology changes too fast. Many have a hard time with small phone text, forget passwords, or worry about online tricks. “I once lost 500 yuan on my phone. Now I’m scared to use my phone,” shared Auntie Wang. To help, communities are taking action. Young volunteers teach seniors how to use phones safely every weekend. In Beijing, a 16-year-old boy named Xiaoming became a “tech-teacher” for his neighbors. “Mr. Chen learned to send emojis (表情)! He sends me a thumbs-up after each lesson,” Xiaoming said proudly. The government also opened special “tech-cafes” with large-screen computers and friendly guides. As 5G networks reach more places, even villages are joining the digital age. The key is to make technology kind to people of all ages. After all, today’s young “phone experts” will one day be seniors (较年长者) too. By working together, every age can enjoy the benefits of a connected world. Digital life not only brings us joy but also prepares us for future jobs. Many jobs today require computer and internet skills.

Traditional media, such as newspapers, radio, and television, once dominated how people consumed information and entertainment. However, with the rise of the internet and digital technology, these platforms now face unprecedented challenges. According to recent statistics, the global digital media market is expected to reach $350 billion by 2025, while print media continues to decline, with newspaper circulation dropping by nearly 50% since the early 2000s. Digital media has revolutionized how content is created, distributed, and consumed. Social media platforms like Facebook, Twitter, and Instagram have become primary sources of news for many users, especially younger generations. These platforms enable instant sharing of information, allowing news to spread virally within minutes. However, this speed has also led to challenges, such as the spread of misinformation and “fake news”, which traditional media outlets with established fact checking processes are less prone to. Another significant shift is the rise of streaming services like Netflix, Hulu, and Disney+, which have transformed how people watch television and movies. Unlike traditional broadcast networks, these services offer on-demand content, allowing viewers to watch what they want, when they want. This shift has led to a decline in traditional TV viewership, with younger audiences increasingly turning to streaming platforms for their entertainment needs. The advertising industry has also evolved dramatically. Digital advertising now accounts for over 50% of all advertising spending globally, surpassing traditional methods like TV commercials and print ads. Advertisers are increasingly leveraging data analytics to target specific demographics, making digital ads more effective and personalized. Despite these changes, traditional media is not disappearing entirely. Instead, many organizations are adapting by integrating digital strategies. For example, newspapers like The New York Times have shifted their focus to digital subscriptions, while TV networks are launching their own streaming services. This hybrid approach suggests that the future of media may not be a replacement of old by new, but rather a coexistence where each platform leverages its unique strengths. 1．What is the primary reason for the decline of traditional media like newspapers and television? A．Increased production costs B．The rise of digital media and the internet C．Decreased interest in news and entertainment D．Government regulations on media companies 2．Which of the following is a challenge associated with social media as a news source? A．Faster distribution of news B．Spread of misinformation and fake news C．Increased engagement with content D．Higher quality of journalistic standards 3．What has contributed to the growth of streaming services? A．The decline of movie theaters B．The availability of on-demand content C．The increase in traditional TV viewership D．The decrease in internet speeds 4．How has the advertising industry adapted to media changes? A．By focusing solely on print advertisements B．By reducing overall advertising budgets C．By using data analytics for targeted ads D．By eliminating digital advertising 5．What strategy are traditional media companies using to remain relevant? A．Completely abandoning digital platforms B．Integrating digital strategies with their existing models C．Relying exclusively on government support D．Ignoring changes in consumer behavior 【答案】1．B 2．B 3．B 4．C 5．B 【导语】本文是说明文。文章围绕过去几十年媒体领域的变革展开，客观介绍了传统媒体的衰落、数字媒体的兴起及特点、广告行业的适应变化，以及传统媒体的转型策略，旨在向读者清晰阐述媒体格局的转变及发展趋势。 1．细节理解题。根据“The media landscape has undergone a dramatic transformation over the past few decades ...

Thanks to creative AI, this dream is now a reality! Scientists from Massachusetts Institute of Technology (MIT) developed a system called Future You. To reduce (减少) worries and help make better decisions, the system lets people talk to their future selves. According to studies, imagining your future self can greatly change long-term choices. You may realize how much money you need to save for the future. You may also change your attitude towards study at school. The system makes the simulation (模拟) so real that it shows clear details. It’s better than just imagining the future without doing anything. Here’s how it works. First, users answer many questions about their lives now. They also share their important things and future plans. Then, Future You creates a digital version (电子版) of the user at age 60. This future self can answer questions about the coming future and give useful tips. In a user study, after talking with Future You for about 30 minutes, people said they felt less worried and had a stronger sense of connection with their future selves. Pat, who finished further studies at MIT’s Media Lab, said, “We don’t have a real time machine, but this version helps people think about the results of their choices today. If you get advice from a future ‘you’, it can be more helpful than receiving it from a regular AI.” This meaningful experience can help people see themselves and the world differently. 1．Why did scientists develop the Future You system?

In a clear tank of water (水箱), fish are swimming happily. Wait a second, take a closer look at that blue one. It is actually a robot! This scene happened at an event, the World Digital Education Conference, from May 14th to 16th in Wuhan, Hubei province. Besides blue ones, there were red and yellow robotic fish, too. It is scientists at Wuhan University who have made them. At the length of about 53 centimeters, the fish were very lifelike. The joints (关节) in their heads and tails were made in a special way to let the fish move fast and easily. This is thanks to bionic engineering (仿生工程), which brings together nature and man-made things. “I love to see the bionic fish,” Professor James Crabbe from Oxford University told Jiupai News, “It could tell us much more about fish swarming and how fish behave (表现).” In fact, swarming in fish means they swim together in large groups. It helps them stay safe, find food and save energy (能量). Learning about swarming helps us understand how fish live and how changes in the environment matter to them. As for the pretty colors of the bionic fish, they come from the LED lights on their bodies, said People’s Daily. These lights can also make shadows, giving the underwater world a party feel. Even better, the bionic fish are smart. With the help of AI and sensors (传感器), they can “see” things in their way and learn to avoid them, said Changjiang Daily. The fish are already helping in the study of the Yangtze River’s water to help protect the environment. What amazing fish they are! 1．Which scene can be seen at the event in Wuhan? A． B． C． D． 2．What makes the bionic fish move fast and easily? A．Different colors. B．Special water tanks. C．Lifelike length. D．Body joints. 3．What can we know about swarming in fish? A．Swarming can keep fish free from any danger. B．Swarming makes it harder for fish to feed themselves. C．Swarming helps scientists learn about the habits of fish. D．Swarming may change the living environment of fish. 4．Which goal may be achieved with bionic fish? A．The quality of the Yangtze River’s water will be improved. B．More bridges over the Yangtze River have been built. C．Bionic fish take the place of fish in the Yangtze River. D．More ships begin to travel along the Yangtze River. 5．What might be the best title for the passage? A．Look! They’re dancing. B．Wait, that’s no fish! C．Stop! Don’t feed them. D．Hey, let’s try fishing! Our digital lives are full of both opportunities and challenges. Smartphones, tablets, and computers have made our lives more convenient. We can shop online, chat with friends, and learn new things at any time. Social media platforms allow us to share our experiences and stay connected with others. However, there are also problems. Spending too much time on digital devices can lead to eye strain and other health issues. Also, we need to be careful about protecting our personal information from hackers.

The AI Baby volunteer team was started by Sheng Jianzhong, a student at Huazhong University of Science and Technology in Wuhan. Sheng studies digital image processing (数字图像处理). One day, when he watched TV, he saw blurry photos of missing children. He thought, “We need clearer pictures to help these kids and their families.” So, he called his classmates and formed a team. They wanted to use AI to make a difference. After six months of hard work, the team made an AI program. This program can turn blurry photos into clear ones. These clear photos are then shared online and offline. Thanks to their efforts, 19 children who were abducted (被拐) have returned home. And they have given hope to over 1,000 families by restoring photos of their missing relatives. Sheng said, “We call it ‘restoration’, but actually, these photos are made by AI. They look so much like the real ones that it’s hard to tell the difference!” One of their most famous cases was helping find Sun Zhuo, who was taken away in 2007. The only clue was a blurry picture of the kidnapper (拐卖者) from a camera. The AI team helped the police identify (确定) the criminal. Finally, in 2021, Sun Zhuo and his father met again. Volunteers from Taiwan also joined this meaningful work. Yen Hsu-hui, who was born in Taiwan, joined the team almost a year ago. His mother works in elderly care in Taiwan. She often talks to old people who came from the Chinese mainland. Yen said, “Some of these old people find their families on the mainland, but others die without seeing their loved ones again.” Yen tells people in Taiwan about this AI way to find lost relatives. Chang Shao-lin, a 20-year-old volunteer from Taiwan, said, “I became a volunteer because I want more people to find their families, just like I did.” This team’s work shows how technology and kindness can help make the world a warmer place. 1．How did the AI Baby volunteer team help the police find Sun Zhuo? A．By talking to the criminal directly. B．By making a blurry picture of the criminal clear with AI. C．By asking volunteers in Taiwan for help.

A．To introduce how to use AI to take better photos. B．To show the difficulties of finding missing children. C．To tell the story of a volunteer team using AI to help families reunite. D．To explain why volunteers from Taiwan joined the team. 4．Why did Yen Hsu-hui join the volunteer team? A．Because his mother asked him to do so. B．Because he wanted to help old people in Taiwan find their mainland relatives. C．Because he was interested in digital image processing. D．Because he wanted to learn more about AI technology. 5．What can we infer from Chang Shao-lin’s words? A．He has found his own roots with the team’s help. B．He believes everyone should study AI. C．He thinks finding roots is not important. D．He will leave the team soon. Nowadays more and more children seem to get lost in a “sea of digital (数字的) technology”. To be honest, they use digital technology too much. They are losing their skills to do simple things. They can’t make toys themselves with hands or help Mom cook dinner. And worst of all, they seem to be losing interest in communicating with others. “I have talked with a number of teachers. They care about the rising numbers of young pupils who can play with computers or smart phones, but have few or no skills to make things,” said a teacher, Colin Kinney. “Many pupils can’t communicate with other pupils, but their parents are glad to see the skills of their children to use a computer or a smart phone.” Instead of playing with other children, more and more children are choosing to stay indoors and quietly play with a tablet (平板电脑) on weekends and after school. How can a child grow up to be a very good artist unless he learns how to use a paintbrush and develop his painting skill? How can a child learn to make friends as he gets older unless he learns to communicate with others at a young age? Digital technology can be used for good or bad. We can use a stone to either break a window or build a house. We shouldn’t blame the children. We should help them make right choices. It is certainly necessary for children to know how to use digital technology in today’s world, but what is more important is that we should encourage them to develop social abilities (社交能力) which are good when they grow up. 1．What’s the worst problem in the first paragraph? A．Children can’t make things themselves. B．Children make too many friends online. C．Children don’t want to communicate with others.

D．It’s difficult for teachers to make right choices for the pupils. 进阶拓展训练5篇 Now in countries like the USA, more and more children seem to get lost in a “sea of digital technology (数字技术)”. As they use digital technology too much, they are losing their ability to do simple things. They can’t make toys themselves with hands or help Mum cook dinner. And worst of all, they seem to be losing interest in communicating with others. “I have talked with a number of teachers. They care about the increasing numbers of young pupils who can play with computers or smartphones, but have few or no skills to make things.” said a teacher. “Many pupils can’t communicate with other pupils but their parents talk proudly of their ability to use a computer or a smartphone.” Instead of playing with other children, more and more children are choosing to stay indoors and quietly play on a tablet (平板电脑) at weekends and after school. How can a child grow up to be a very good artist if he doesn’t learn how to use a paintbrush and develop his painting skill? How can a child learn to make friends as he gets older if he doesn’t learn to communicate with others at a young age? We can use a stone to either break a window or build a house. Digital technology can be used for good or bad. We shouldn’t blame the children. We should help them make right choices. It is certainly necessary for children to know how to use digital technology in today’s world, but more importantly, we should encourage them to develop social abilities which will do them good when they grow up. 1．According to paragraph 1, what’s the worst problem?

The Development of Digital Cameras Digital cameras have come a long way since their invention. In the early days, digital cameras had very low-resolution images. They could only take a few pictures and the quality was not very good. But as technology advanced, digital cameras improved rapidly. Today, most digital cameras have high-resolution sensors, which can take very clear and detailed pictures. They also have a large storage capacity, allowing users to store hundreds or even thousands of photos. Another great improvement is the zoom function. Modern digital cameras can zoom in and out smoothly, making it easier to capture distant objects. And with the development of digital technology, cameras can now take high-quality videos as well. Moreover, digital cameras have become more and more portable. They are small and light, so we can carry them around easily and capture every beautiful moment in our lives. 1．What were digital cameras like in the early days? A．They had high resolution images. B．They could take many pictures. C．They had low-resolution images and could take only a few pictures. D．They were very expensive. 2．What makes digital cameras able to take clear and detailed pictures today? A．High-resolution sensors. B．Large storage capacity. C．Good zoom function. D．Portable design. 3．What new function do modern digital cameras have compared to the early ones? A．They can store more photos. B．They can zoom in and out. C．They can take high-quality videos. D．All of the above. 4．Why are digital cameras more convenient now? A．Because they are small and light. B．Because they are very cheap. C．Because they have a long battery life.

D．How to choose a digital camera. “You’ll get square eyes!” my mother used to say as I sat for hour after hour glued to the TV. I ignored her, of course. Fast-forward a few decades and now I’m the parent. My 5-year-old lives in a world where screens aren’t fixed pieces of furniture. You can’t even avoid them by going outside. Screens are not only in our pockets. They’re everywhere. The concerns have grown with the screens. In the past decade, we have heard that they will damage our mental health. Many of us feel more distracted by them, feeling guiltier and more tired as a result. The apps and websites we can access on our phones have also sparked widespread concern. Big tech companies are also good at making use of our need for social recognition, hooking us on likes, retweets and follower counts. Social media has created a culture of mass narcissism (自恋), which has led many to worry about the emotional stresses on teenagers. A quick online search brings up dozens of papers linking screen use or social media with harmful effects on mental health, including depression and suicide. Such statements are alarming. They are also widely believed, thanks to popular books like iGen by Jean Twenge, which claims that digital technology has ruined a generation. Yet, Amy Orben at the University of Oxford, who studies the impact of digital technology and social media in particular on mental health, holds different views. She claims that the underlying data can be used to tell different stories. She also spotted shortcomings in several large studies that claimed to show correlations (相关性) between the use of devices with screens and depression in users. Twenge stands by her own findings, pointing in turn to what she considers flaws in Orben’s research methods. For David Max, at Royal College of Child Health in London, the effect of screen time and social media use on mental health remains speculative. “We cannot regard social media overall as good or bad,” says David. “We don’t know whether in individual cases social media is not responsible,” he says. The explosion of mobile phone use has revolutionized our lives. I can download movies, write articles, communicate with my family and broadcast to the world all at the push of a button. Rather than impose constraints (限制), we should take a look at our use of screens and ask how they fit with the activities and lifestyle. Every new technology with widespread impact has given rise to new fears. So the best bet may simply be to ask yourself what level of screen use makes you and those around you happy and try to stick to it. If you find yourself overly addictive, don’t panic—and certainly don’t feel guilty. Nobody knows anything worth getting scared about. 1．According to the passage, people give likes, retweet or count followers to ________. A．share one’s lifestyles B．show respect for others C．seek social recognition D．relieve emotional stresses 2．The underlined word “speculative” probably means “________”.

B．Orben claims it is far too early to blame screen use for ruining a generation. C．Big tech companies help to produce many research papers on mental health. D．Twenge mainly introduces the overall benefits of digital technology in her books. 4．The passage is written to ________. A．encourage readers to reduce the time of screen use B．share different opinions on the effects of screen use C．explain why screen use may have negative effects on people D．relieve people’s concerns and worries about the use of screens Nowadays, more and more people like to watch short videos. Many short-video platforms (平台) have become a main part of digital life (数字生活), such as TikTok, Instagram Reels, and YouTube Shorts. Studies show that people spend much time watching short video s every day. There are two charts about watching short videos. As for teenagers, short video s can actually help them if used right. They're great for learning interesting things, getting better at studying, and taking quick breaks between homework. Just remember to pick useful videos, watch for only 15-20 minutes at a time, and stop when time's up.

With the help of digital technology (技术), villagers are living an easier and happier life. Farming in the past was not an easy job. Farmers worked hard all year round. At the same time, they usually found it difficult to solve problems like plant diseases and pest (害虫). Now, there have been big changes in farming. For example, in Dayi County, Sichuan Province, AI machines help local farmers know when and how to fertilize (施肥) and kill pests. In this way, they make farmers work more easily with less time and energy. Thanks to the Internet, a new business called rural e-commerce (乡村电子商务) grows. Selling fresh fruit and vegetables to cities is faster. The business also helps villagers live a digital life. They can get many things done on different kinds of apps. They can also use drones to help with their farm work. More visitors travel in beautiful villages because of digital technology. A good example is Huacheng Town, Guangdong Province. Visitors can know where to park their cars for free, when to book a ticket easily and what to buy online. They can also enjoy the view of nearly every part of the town by using VR. 1．According to Paragraph 2, we know AI machines can help farmers ________. A．water the crops B．harvest the crops C．know when and where to fertilize D．save time and energy on farming 2．What is the structure of this passage? (①= Paragraph 1, ②= Paragraph 2...) A． B． C． D． 3．What is the best title of this passage? A．Better village life. B．Tourism in villages. C．The digital technology. D．A new business in villages. Life for the old is changing quickly because of technology. While some find joy in these changes, others face difficulties. Many seniors are discovering fun ways to use technology. Free online classes let them learn painting, gardening, or even how to use smartphones. For example, 72-year-old Grandma Zhang recently learned to make digital (数字的) birthday cards for her grandchildren. Video apps like WeChat help families stay connected. “I see my grandson’s face every day though he studies abroad,” said Mr. Li, 68, with a smile. Smartwatches are also popular—they check heart rates and remind users to take medicine. Some hospitals even let patients talk to doctors online, saving time for those who have trouble walking. However, not everything is easy. About 40% of people over 65 say technology changes too fast. Many have a hard time with small phone text, forget passwords, or worry about online tricks. “I once lost 500 yuan on my phone. Now I’m scared to use my phone,” shared Auntie Wang. To help, communities are taking action. Young volunteers teach seniors how to use phones safely every weekend. In Beijing, a 16-year-old boy named Xiaoming became a “tech-teacher” for his neighbors. “Mr. Chen learned to send emojis (表情)! He sends me a thumbs-up after each lesson,” Xiaoming said proudly. The government also opened special “tech-cafes” with large-screen computers and friendly guides. As 5G networks reach more places, even villages are joining the digital age. The key is to make technology kind to people of all ages. After all, today’s young “phone experts” will one day be seniors (较年长者) too. By working together, every age can enjoy the benefits of a connected world. Digital life not only brings us joy but also prepares us for future jobs. Many jobs today require computer and internet skills. So, let’s enjoy digital life wisely, stay safe, and keep a balance.This way, we can make the most of it and be ready for the future. 根据材料内容选择最佳答案。 1．How many good things does technology bring to seniors?

The media landscape has undergone a dramatic transformation over the past few decades. Traditional media, such as newspapers, radio, and television, once dominated how people consumed information and entertainment. However, with the rise of the internet and digital technology, these platforms now face unprecedented challenges. According to recent statistics, the global digital media market is expected to reach $350 billion by 2025, while print media continues to decline, with newspaper circulation dropping by nearly 50% since the early 2000s. Digital media has revolutionized how content is created, distributed, and consumed. Social media platforms like Facebook, Twitter, and Instagram have become primary sources of news for many users, especially younger generations. These platforms enable instant sharing of information, allowing news to spread virally within minutes. However, this speed has also led to challenges, such as the spread of misinformation and “fake news”, which traditional media outlets with established fact checking processes are less prone to. Another significant shift is the rise of streaming services like Netflix, Hulu, and Disney+, which have transformed how people watch television and movies. Unlike traditional broadcast networks, these services offer on-demand content, allowing viewers to watch what they want, when they want. This shift has led to a decline in traditional TV viewership, with younger audiences increasingly turning to streaming platforms for their entertainment needs. The advertising industry has also evolved dramatically. Digital advertising now accounts for over 50% of all advertising spending globally, surpassing traditional methods like TV commercials and print ads. Advertisers are increasingly leveraging data analytics to target specific demographics, making digital ads more effective and personalized. Despite these changes, traditional media is not disappearing entirely. Instead, many organizations are adapting by integrating digital strategies. For example, newspapers like The New York Times have shifted their focus to digital subscriptions, while TV networks are launching their own streaming services. This hybrid approach suggests that the future of media may not be a replacement of old by new, but rather a coexistence where each platform leverages its unique strengths. 1．What is the primary reason for the decline of traditional media like newspapers and television? A．Increased production costs B．The rise of digital media and the internet C．Decreased interest in news and entertainment D．Government regulations on media companies 2．Which of the following is a challenge associated with social media as a news source? A．Faster distribution of news B．Spread of misinformation and fake news C．Increased engagement with content D．Higher quality of journalistic standards 3．What has contributed to the growth of streaming services?

A．By focusing solely on print advertisements B．By reducing overall advertising budgets C．By using data analytics for targeted ads D．By eliminating digital advertising 5．What strategy are traditional media companies using to remain relevant? A．Completely abandoning digital platforms B．Integrating digital strategies with their existing models C．Relying exclusively on government support D．Ignoring changes in consumer behavior Have you ever dreamed about traveling through time to meet your future self? Thanks to creative AI, this dream is now a reality! Scientists from Massachusetts Institute of Technology (MIT) developed a system called Future You. To reduce (减少) worries and help make better decisions, the system lets people talk to their future selves. According to studies, imagining your future self can greatly change long-term choices. You may realize how much money you need to save for the future. You may also change your attitude towards study at school. The system makes the simulation (模拟) so real that it shows clear details. It’s better than just imagining the future without doing anything. Here’s how it works. First, users answer many questions about their lives now. They also share their important things and future plans. Then, Future You creates a digital version (电子版) of the user at age 60. This future self can answer questions about the coming future and give useful tips. In a user study, after talking with Future You for about 30 minutes, people said they felt less worried and had a stronger sense of connection with their future selves. Pat, who finished further studies at MIT’s Media Lab, said, “We don’t have a real time machine, but this version helps people think about the results of their choices today. If you get advice from a future ‘you’, it can be more helpful than receiving it from a regular AI.” This meaningful experience can help people see themselves and the world differently. 1．Why did scientists develop the Future You system? A．To have and realize a dream. B．To meet and talk to future people. C．To reduce worries and improve choices. D．To time-travel and meet future scientists. 2．How does Future You work first? A．By answering users’ questions. B．By giving users some useful advice. C．By making an image of users in old age. D．By getting users’ personal information. 3．What can we infer (推断) from Pat’s words? A．Future You will have a real time machine. B．Future You will replace human decisions. C．Future You gives better advice than a regular AI. D．Future You can bring us to real places in the future. 4．What is the author’s attitude towards the“Future You” system? A．Hopeful. B．Nervous. C．Doubtful. D．Complaining. 5．Which can be the best title for the passage? A．AI Can Tell You What Will Happen Exactly. B．AI Helps People Talk to Their Future Selves. C．Scientists Invent a Time Machine for the Future. D．Talking to Your Future Self Makes You Study Better. 12 同步新教材，周周有练习，月月有重点！ 17 同步新教材，周周有练习，月月有重点！ 学科网（北京）股份有限公司 $$
