Apps like DeepSeek make AI more useful in our daily lives. It also helps students learn English in fun ways, making studying easier and more effective (有效的). It can help students improve faster. When students get English homework, DeepSeek can turn difficult words into easy study cards. For example, if a teacher gives a list like “cheat, cartwheel, blind,” DeepSeek adds meanings, phonetic symbols (音标), and example sentences. Boring word lists become interesting cards with pictures. These colorful cards make memorizing faster and more enjoyable. DeepSeek can write short stories using students’ new words. For a unit about animals, it might make a story like The Fox and the Tiger, where key words appear in bold. Teachers also use it to design tests that match textbook units. Over 80% of users say DeepSeek makes English less difficult. One boy shared, “Now I finish homework quickly and play soccer sooner!” Its smart work helps both beginners and good learners. However, we should remember not to depend on DeepSeek too much. It’s just a tool to help us. We still need to think by ourselves and try to solve problems on our own.

But do you know about junk sleep? Junk sleep is when you don’t get enough sleep or the sleep you get is not of good quality. A study in the UK was about how electronic devices (电子设备) in teenagers’ bedrooms affect their sleep. The survey (调查) was done among 1,000 British kids aged 12 to 16. It found that 30 percent of them got just 4 to 7 hours sleep every day, and they needed about 8 hours to feel good and do well in school. Almost a quarter of the kids said they fell asleep many times while listening to music or using other electronic devices. “This is very worrying,” said Dr. Chris Idzikowski, a British expert. “We call it ‘junk sleep’. It means you don’t get enough sleep, and the quality of the sleep is bad, too. If you don’t get good rest, you don’t do well in the school the next day.” ▲ The survey found that 40 percent of kids felt tired every day, with girls aged 15 to 16 feeling the worst. Nearly all teenagers have a phone, music tool, or TV in their bedroom. Using electronic devices too often is harmful to teenagers. Phones, iPads, and TVs can keep you awake and make your sleep less good. To have better sleep, try to keep your bedroom a quiet and dark place, without electronic devices. Remember, good sleep helps you learn and play better.

B．Because they can reduce the quality of sleep. C．Because they are too expensive to leave in bedrooms. D．Because they are useless while people are sleeping. 4．What is the best title for the passage? A．Keep off Electronic Devices B．Junk Food and Our Health C．Stay Away from Junk Sleep D．A Study of British Kids The Internet is becoming more and more important in our lives.

They can find information about their lessons, read e-books and watch educational videos. It can help them study better. But the Internet also has some problems. Some students spend too much time playing online games. This is bad for their eyes and studies. Also, there is a lot of bad information on the Internet. Students need to be careful and not believe everything they see. Parents and teachers should help students use the Internet correctly. They can set rules about how long students can use the Internet and what they can do on it. Students should also learn to use the Internet in a healthy way. They can use it for study and useful activities instead of just playing games. In a word, the Internet can be very helpful, but we need to use it properly. 1．What can students do on the Internet according to the passage? A．Only play games. B．Only shop.

A．The Internet Is Bad B．How to Use the Internet Correctly C．Students and the Internet D．The Internet in Our Lives In today’s digital (数字的) world, the internet is part of our daily lives—but it also brings risks. Staying safe online, or cybersafe, is a skill everyone needs to learn. Protect Your Personal Data: You might share photos or your school name on social apps. But if you don’t set strong privacy settings, strangers can see this information. Every picture or message you post online can be saved and shared without your permission, and it’s almost impossible to remove it forever. Also, never click links or open files from people you don’t know—they could carry a virus that breaks your phone or computer. Spot False Information: The internet makes it easy to find news, but not everything you read is true. Before you believe a story, ask: Who wrote it? Is the writer an expert or just a random user? Is the website a trusted one, like a school or news site, or a personal blog? Some posts are only made to get attention, not to tell the truth. Stop Online Bullying: Online bullying, or cyberbullying, happens when people send mean messages, spread lies, or share others’ private photos online. These actions hurt the victim deeply. If this happens to you, the first steps are to ignore the messages, block the person, and delete the posts. You should also talk to a parent or teacher you trust, especially if you feel scared or threatened (受到威胁的). To stay cybersafe, always think before you share, check if information is true, and be kind to others online. 1．What may happen if you click a link from a stranger? A．You get a free gift. B．Your device may get a virus. C．You make a new friend. D．Your privacy settings improve. 2．What is the main idea of the paragraph 3? A．The internet is full of lies. B．How to find free information online. C．How to check if online information is true. D．Why people write false stories. 3．What does the underlined word “victim” mean in the text? A．Target. B．Bully. C．Helper. D．User. 4．What should you do if you feel threatened? A．Fight back online. B．Talk to a parent. C．Share the problem online. D．Keep it a secret. 5．What is the best title for this text? A．How to Use Social Media B．The History of the Internet C．Learn Cyberskills to Stay Safe D．How to Make Friends Online Nowadays, using AI is becoming more and more popular. Smart AI tools are now entering our lives and greatly changing them. You might wonder if AI can help with schoolwork. The answer is “yes”, but first you should get permission (许可) from your teacher. AI can offer different kinds of help, for example, you can use it to search for information on space exploration for science homework, or ask it to show you how to solve a math problem. However, you should do your work on your own first-don’t just copy from AI. Always think by yourself and check if the information is correct. AI can only be your tool, teacher, or guide. But is AI always reliable? Not really. Although it is smart, it isn’t perfect. AI keeps learning, but it can still make mistakes. Always use it carefully and think critically. Remember, AI is a useful tool for learning, but it’s important to ask teachers or parents how to use it correctly. 1．How does the writer start the text? A．By telling a story. B．By describing a current trend (当前趋势). C．By asking a question. D．By comparing two facts. 2．What is Paragraph 2 mainly about? A．How to use AI correctly in schoolwork. B．Why AI is helpful for homework. C．The importance of using AI carefully. D．Ways to make AI’s answers more useful. 3．What does the underlined word “reliable” in Paragraph 3 mean? A．funny to use B．able to be trusted (信任) C．expensive to buy D．easy to carry 4．What can we infer (推断) about using AI for schoolwork? A．Teachers will lose their jobs. B．Students still need some human help. C．It always gives correct answers. D．Parents dislike AI tools. 5．Which would be the best title for the text? A．How to Build Your Own AI B．Why AI Appeared C．Using AI Smartly for School D．The History of AI Tools Today, more than one billion Chinese people use the internet every day. As more people use the internet, risks also increase. So how can we stay healthy and safe while making good use of the internet?   First, use the internet to learn new skills and look up useful information. Read news from safe websites and study online. Keep a simple daily plan for your time online and follow it.   Second, do not spend too much time online. Too much screen time is harmful to your health. Set a time to go online each day and take a break on time.   Third, protect your personal information. Do not share your password, address, phone number, or ID number with strangers online. Double-check a link before you click it.   Finally, if you get a bad message from someone, do not reply. Take a picture of the screen and keep a record.

A．The History of the Internet B．How to Use the Internet Wisely C．The Dangers of the Internet ①Imagine wearing a magic hat that allows you to write words down just by thinking of them. This is not a sci-fi (科幻) story, but actual research done by students at Tianjin University. They used brain-computer interface (接口) (BCI) technology to write the character “fu (福)”. It’s written by a robotic arm controlled by their researchers’ minds. ②A brain-computer interface is like a bridge between our brain and the computer. It lets our brain talk directly to the computer so that we can control the computer just by thinking. How does it work? ③First, special machines pick up the signals (信号) from our brain. These signals are like little secrets from our brain. Then, the machines make these signals stronger, clean them up, and change them into something that computers can understand. After that, these signals become orders to control the devices (设备). So, we can use our minds to make machines work. ④Countries all over the world are working hard on BCI technology. In the future, BCI technology will be useful in many areas: ⑤Medical Help: People who have lost their hands or arms can use BCI to write messages and surf the Internet. It can also help people who can’t talk to speak again and treat some other diseases (疾病). ⑥Games: When playing VR or AR games, players won’t need to use their hands to control. Just thinking about an action will make the game character move right away. It will be very real and exciting. ⑦Travel: In the future, when driving, we might not need to use our hands or feet. Just thinking “go faster” or “turn” will make the car move by itself. It will be safer and easier to travel. 1．What is true about the BCI technology? A．It’s a magic hat. B．It can only be seen in sci-fi stories. C．It’s like a bridge between our brain and the computer. D．It’s a robot arm. 2．How does the BCI technology work?

With just one click, we can do a lot of things at home easily without going out, which brings great convenience to our life. We can do different kinds of things with the Internet. We can search for useful information for our schoolwork, watch wonderful videos, listen to different kinds of music and chat with friends or family members who live far away. Besides, we can also book train tickets or hotel rooms online, and visit different places of interest around the world freely. Because of these advantages, online tours are becoming more and more popular among students and teachers. Many schools choose to use online tours as a new teaching way. It can help students learn better in class. Through online tours, students can visit famous foreign universities, big museums with rich collections and ancient historic sites with long histories.

However, from time to time, we all use passwords and ID numbers on the Internet. We think we are safe, but that may not be true! A new kind of attack (攻击) is being used by dishonest people to steal IDs and credit card numbers from web surfers. This new kind of attack is called “phishing”. Phishing sounds the same as the word “fishing”, and it means that a thief is trying to trick people into giving away valuable information. Like real fishermen, phishers use bait (诱饵) in the form of great online deals or services. For example, phishers might use false emails and websites to trick people into revealing (透露) credit card numbers, account usernames, and passwords. They imitate (模仿) well-known banks, online sellers, and credit card companies. Successful phishers may make as many as 5% of the people believe and give away their personal information. It’s really a big problem! Actually, tricking 5% of the online population is huge. Now more than 4.6 billion people have access (进入权) to the Internet, and 75% of those Internet users live in the wealthiest countries on Earth. It has been reported that phishers send more than 40 billion false messages each year. Even by tricking only 5% of the people, phishers can make a lot of money. Amy, 18, from California, received an email. A man told Amy that she could get a million dollars in her account as a reward if she sent a thousand dollars to him. Amy did as the man said at once. The “thief” used Amy’s Social Security number to get credit cards in her name and transferred her money. How can people avoid being cheated online? Above all, they have to learn to recognize the email that has been sent by a phisher. Always be careful with any email with urgent (紧急的) requests for personal information. Phishers typically write upsetting or exciting, but false, statements in their emails so that people will reply right away. Never give out personal information to phishers. And if an offer sounds too good to be true, it is. 1．What is “phishing” according to the passage? A．A new kind of fishing in the sea. B．A new way to protect personal information online. C．A new type of attack to steal personal information on the Internet. D．A method to make online shopping safer. 2．Which writing skill is used in Para. 3? A．Giving examples. B．Listing numbers. C．Asking questions. D．Using quotes. 3．Why is phishing a serious problem? A．Because phishers only attack people in poor countries. B．Because only a few people use the Internet. C．Because even a small success rate can bring phishers a lot of money. D．Because it is impossible to avoid. 4．Which of the following in the dictionary best explains the underlined word “transferred” in Para. 4? A．to move from one place to another B．to connect the call of someone to someone else’s C．to move money from one account to another D．to change from one bus to another 5．Besides introducing what phishing is, the writer also tells us how to ________. A．help to catch phishers B．reply to urgent emails C．pay by credit card D．protect ourselves online ①AI (artificial intelligence 人工智能) and machine learning refer to the ability of machines to learn and act intelligently. It means they can make decisions, finish tasks, and even tell the possible future results based on what they learn from data (数据). ②AI and machine learning already play a bigger role in everyday life than you might imagine. Health care, banking, video games, every search on the Internet you make..., all are driven by AI. ③AI is going to change almost every field of modern life. Stephen Hawking said, “Success in creating AI would be the biggest event in human history.” And Hawking added at once, “Unluckily, it might also be the last, unless we learn how to avoid the risks.” ④ ________, especially when you consider some countries are racing to develop Al-enabled autonomous weapons (人工智能自主武器). It is also going to change and take the place of many human jobs. The same worries also come from the public. According to the survey result from Centre for the Governance of AI, 91% of the people (tend to and totally)  agree that “AI is a technology that requires careful management” in Europe. ⑤But rather than agreeing with an idea of a helpless future where all human jobs are given over to robots, some people believe AI will make our working lives better. It will improve the work of humans, and new jobs will appear to take the place of the old ones. ⑥What’s more, machines become more intelligent and they are able to finish more human tasks. Things which only belong to humans like creativity and critical (批判性的) thinking, will become even more valuable in the future. ⑦Like it or not, AI is here. Maybe changing ourselves and managing it well are the best way out. Just as Benjamin Franklin once said, “When you’re finished changing, you’re finished.” 1．Which paragraph does the diagram mainly support? A．② B．③ C．④ D．⑤ 2．What words can best describe AI and machine learning according to Para.①and Para.②?

A．To warn us that AI will take humans’ place. B．To show us that there are a lot of uses of AI. C．To tell us that many people are worried about AI. D．To suggest we prepare for the changes brought by AI. 5．Which of the following shows the structure of this passage?

Staying safe online, or cybersafe, is a skill everyone needs to learn. Protect Your Personal Data: You might share photos or your school name on social apps. But if you don’t set strong privacy settings, strangers can see this information. Every picture or message you post online can be saved and shared without your permission, and it’s almost impossible to remove it forever. Also, never click links or open files from people you don’t know—they could carry a virus that breaks your phone or computer. Spot False Information: The internet makes it easy to find news, but not everything you read is true. Before you believe a story, ask: Who wrote it? Is the writer an expert or just a random user? Is the website a trusted one, like a school or news site, or a personal blog? Some posts are only made to get attention, not to tell the truth. Stop Online Bullying: Online bullying, or cyberbullying, happens when people send mean messages, spread lies, or share others’ private photos online. These actions hurt the victim deeply. If this happens to you, the first steps are to ignore the messages, block the person, and delete the posts. You should also talk to a parent or teacher you trust, especially if you feel scared or threatened (受到威胁的). To stay cybersafe, always think before you share, check if information is true, and be kind to others online. 1．What may happen if you click a link from a stranger? A．You get a free gift. B．Your device may get a virus. C．You make a new friend. D．Your privacy settings improve. 2．What is the main idea of the paragraph 3? A．The internet is full of lies. B．How to find free information online. C．How to check if online information is true. D．Why people write false stories. 3．What does the underlined word “victim” mean in the text? A．Target. B．Bully. C．Helper. D．User. 4．What should you do if you feel threatened? A．Fight back online. B．Talk to a parent. C．Share the problem online. D．Keep it a secret. 5．What is the best title for this text? A．How to Use Social Media B．The History of the Internet C．Learn Cyberskills to Stay Safe D．How to Make Friends Online 【答案】1．B 2．C 3．A 4．B 5．C 【导语】本文围绕网络安全展开，针对数字时代互联网的潜在风险，为读者讲解了三大核心网络安全技能。 1．第2段最后一句“Also, never click links or open files from people you don’t know—they could carry a virus that breaks your phone or computer.”明确说明这类链接可能携带病毒，损坏手机/电脑。 2．第3段“Spot False Information…Some posts are only made to get attention, not to tell the truth.”本段核心是“辨别虚假信息”，通过提出三个具体问题，教读者如何验证网络信息的真实性。 3．第4段“Online bullying, or cyberbullying, happens when people send mean messages, spread lies, or share others’ private photos online. These actions hurt the victim deeply.”根据上下文，“victim”指遭受网络欺凌的人，即网络欺凌的目标/受害者；target作名词时意为“目标；受害者”，是最贴合的同义替换。 4．第4段最后一句“You should also talk to a parent or teacher you trust, especially if you feel scared or threatened.”明确给出建议：和信任的父母或老师交谈。 5．本文围绕“网络安全”展开，核心是教读者掌握网络技能以实现网络安全，C项为最佳标题。 Nowadays, using AI is becoming more and more popular. Smart AI tools are now entering our lives and greatly changing them. You might wonder if AI can help with schoolwork. The answer is “yes”, but first you should get permission (许可) from your teacher. AI can offer different kinds of help, for example, you can use it to search for information on space exploration for science homework, or ask it to show you how to solve a math problem. However, you should do your work on your own first-don’t just copy from AI. Always think by yourself and check if the information is correct. AI can only be your tool, teacher, or guide. But is AI always reliable? Not really. Although it is smart, it isn’t perfect. AI keeps learning, but it can still make mistakes. Always use it carefully and think critically. Remember, AI is a useful tool for learning, but it’s important to ask teachers or parents how to use it correctly. 1．How does the writer start the text? A．By telling a story. B．By describing a current trend (当前趋势). C．By asking a question. D．By comparing two facts. 2．What is Paragraph 2 mainly about? A．How to use AI correctly in schoolwork. B．Why AI is helpful for homework. C．The importance of using AI carefully. D．Ways to make AI’s answers more useful. 3．What does the underlined word “reliable” in Paragraph 3 mean? A．funny to use B．able to be trusted (信任) C．expensive to buy D．easy to carry 4．What can we infer (推断) about using AI for schoolwork? A．Teachers will lose their jobs. B．Students still need some human help. C．It always gives correct answers. D．Parents dislike AI tools. 5．Which would be the best title for the text? A．How to Build Your Own AI B．Why AI Appeared C．Using AI Smartly for School D．The History of AI Tools 【答案】1．B 2．A 3．B 4．B 5．C 【导语】文章围绕人工智能工具展开，介绍了AI在学习中的应用方式、使用注意事项以及其局限性，倡导学生在学习中明智、批判性地使用AI工具。 1．文章开篇提到“Nowadays, using AI is becoming more and more popular.”，直接点明了AI工具日益流行的趋势，是通过描述当前趋势来引入话题的。 2．第二段围绕AI在学业中的使用展开，提到“first you should get permission from your teacher”“you should do your work on your own first—don’t just copy from AI”“check if the information is correct”，核心是说明如何正确使用AI完成学业任务。 3．第三段提到“Although it is smart, it isn’t perfect. AI keeps learning, but it can still make mistakes.”，由此可知前文“reliable”指AI并非永远都能给出正确答案，即可靠的、可信任的，对应“able to be trusted”。 4．文中最后一段提到“ask teachers or parents how to use it correctly”，说明学生在使用AI学习时，仍然需要老师或家长的指导与帮助。 5．全文围绕AI在学习中的应用、正确使用方式与注意事项展开，“Using AI Smartly for School” (明智地在学习中使用AI)最能概括文章主旨。 Today, more than one billion Chinese people use the internet every day.

This is not a sci-fi (科幻) story, but actual research done by students at Tianjin University. They used brain-computer interface (接口) (BCI) technology to write the character “fu (福)”. It’s written by a robotic arm controlled by their researchers’ minds. ②A brain-computer interface is like a bridge between our brain and the computer. It lets our brain talk directly to the computer so that we can control the computer just by thinking. How does it work? ③First, special machines pick up the signals (信号) from our brain. These signals are like little secrets from our brain. Then, the machines make these signals stronger, clean them up, and change them into something that computers can understand. After that, these signals become orders to control the devices (设备). So, we can use our minds to make machines work. ④Countries all over the world are working hard on BCI technology. In the future, BCI technology will be useful in many areas: ⑤Medical Help: People who have lost their hands or arms can use BCI to write messages and surf the Internet. It can also help people who can’t talk to speak again and treat some other diseases (疾病). ⑥Games: When playing VR or AR games, players won’t need to use their hands to control. Just thinking about an action will make the game character move right away. It will be very real and exciting. ⑦Travel: In the future, when driving, we might not need to use our hands or feet. Just thinking “go faster” or “turn” will make the car move by itself. It will be safer and easier to travel. 1．What is true about the BCI technology? A．It’s a magic hat. B．It can only be seen in sci-fi stories. C．It’s like a bridge between our brain and the computer. D．It’s a robot arm. 2．How does the BCI technology work? Choose the right order. a. make the signals stronger b. pick up the signals c. control the devices d. change the signals into orders A．a→d→b→c B．b→a→d→c C．b→d→c→a D．a→c→b→d 3．In the passage, the BCI technology can be used in areas mentioned EXCEPT in ________. A．Study B．Games C．Travel D．Medical Help 4．Which is NOT true about the usage (应用) of the BCI technology? A．People can talk with the help of BCI. B．The BCI technology can help treat some diseases. C．BCI technology makes it safer and easier to drive a car. D．In VR or AR games, players just need to use their hands to control. 5．How can you divide the passage properly? A．①/②③④⑤⑥⑦ B．①②/③④/⑤⑥⑦ C．①②③/④⑤/⑥⑦ D．①/②③/④⑤⑥⑦ 【答案】1．C 2．B 3．A 4．D 5．D 【导语】本文是一篇说明文，主要介绍了天津大学学生利用脑机接口（BCI）技术进行的研究，阐述了脑机接口技术的概念、工作原理以及在未来医疗、游戏、旅行等多个领域的应用。 1．第二段指出“A brain-computer interface is like a bridge between our brain and the computer.”，这直接说明脑机接口技术就像我们大脑和计算机之间的一座桥梁。 2．第三段说明脑机接口技术的工作原理：“First, special machines pick up the signals (信号) from our brain.” “Then, the machines make these signals stronger, clean them up, and change them into something that computers can understand.” “After that, these signals become orders to control the devices (设备).”，所以正确顺序是b→a→d→c。 3．文章第四段提到“In the future, BCI technology will be useful in many areas”，接着第五段提到“Medical Help”、第六段提到“Games”、第七段提到“Travel”，未提及“Study”。 4．第六段提到“When playing VR or AR games, players won’t need to use their hands to control. Just thinking about an action will make the game character move right away.”，而D选项说在虚拟现实或增强现实游戏中，玩家只需要用手来控制，与原文不符。 5．第一段通过天津大学学生利用脑机接口技术写“福”字引出话题；第二、三段介绍脑机接口技术的概念和工作原理；第四、五、六、七段介绍脑机接口技术在医疗、游戏、旅行等领域的应用，所以文章结构划分正确的是①/②③/④⑤⑥⑦。 Now the Internet plays an important role in our daily life.

However, from time to time, we all use passwords and ID numbers on the Internet. We think we are safe, but that may not be true! A new kind of attack (攻击) is being used by dishonest people to steal IDs and credit card numbers from web surfers. This new kind of attack is called “phishing”. Phishing sounds the same as the word “fishing”, and it means that a thief is trying to trick people into giving away valuable information. Like real fishermen, phishers use bait (诱饵) in the form of great online deals or services. For example, phishers might use false emails and websites to trick people into revealing (透露) credit card numbers, account usernames, and passwords. They imitate (模仿) well-known banks, online sellers, and credit card companies. Successful phishers may make as many as 5% of the people believe and give away their personal information. It’s really a big problem! Actually, tricking 5% of the online population is huge. Now more than 4.6 billion people have access (进入权) to the Internet, and 75% of those Internet users live in the wealthiest countries on Earth. It has been reported that phishers send more than 40 billion false messages each year. Even by tricking only 5% of the people, phishers can make a lot of money. Amy, 18, from California, received an email. A man told Amy that she could get a million dollars in her account as a reward if she sent a thousand dollars to him. Amy did as the man said at once. The “thief” used Amy’s Social Security number to get credit cards in her name and transferred her money. How can people avoid being cheated online? Above all, they have to learn to recognize the email that has been sent by a phisher. Always be careful with any email with urgent (紧急的) requests for personal information. Phishers typically write upsetting or exciting, but false, statements in their emails so that people will reply right away. Never give out personal information to phishers. And if an offer sounds too good to be true, it is. 1．What is “phishing” according to the passage? A．A new kind of fishing in the sea. B．A new way to protect personal information online. C．A new type of attack to steal personal information on the Internet. D．A method to make online shopping safer. 2．Which writing skill is used in Para. 3? A．Giving examples. B．Listing numbers. C．Asking questions. D．Using quotes. 3．Why is phishing a serious problem? A．Because phishers only attack people in poor countries. B．Because only a few people use the Internet. C．Because even a small success rate can bring phishers a lot of money. D．Because it is impossible to avoid. 4．Which of the following in the dictionary best explains the underlined word “transferred” in Para. 4? A．to move from one place to another B．to connect the call of someone to someone else’s C．to move money from one account to another D．to change from one bus to another 5．Besides introducing what phishing is, the writer also tells us how to ________. A．help to catch phishers B．reply to urgent emails C．pay by credit card D．protect ourselves online 【答案】1．C 2．B 3．C 4．C 5．D 【导语】本文是一篇说明文，文章主要介绍了网络诈骗手段“钓鱼诈骗（phishing）”的定义、作案方式、危害性，并结合案例说明该诈骗的严重后果，最后给出了避免网络受骗的防护方法。 1．细节理解题。根据“A new kind of attack (攻击) is being used by dishonest people to steal IDs and credit card numbers from web surfers. This new kind of attack is called ‘phishing’.”可知，phishing是一种在网络上盗窃个人信息的新型攻击手段，故选C。 2．细节理解题。根据“Now more than 4.6 billion people have access (进入权) to the Internet, and 75% of those Internet users live in the wealthiest countries on Earth. It has been reported that phishers send more than 40 billion false messages each year. Even by tricking only 5% of the people, phishers can make a lot of money.”可知，如今有超过46亿人能上网，其中75%的网民生活在世界上最富裕的国家。据报道，钓鱼诈骗者每年发送超过400亿条虚假信息。故本段运用了列数字的写作手法，故选B。 3．细节理解题。根据“Even by tricking only 5% of the people, phishers can make a lot of money.”可知，钓鱼诈骗是严重问题的原因是即便成功率低，也能让诈骗者获得巨额钱财，故选C。 4．词句猜测题。根据“The ‘thief’ used Amy’s Social Security number to get credit cards in her name and transferred her money.”可知，这个“骗子”用艾米的社保号办理了以她名义的信用卡，并转走了她的钱，故可推测出，transferred在此处表示“将钱从一个账户转到另一个账户”，故选C。 5．细节理解题。根据“How can people avoid being cheated online? Above all, they have to learn to recognize the email that has been sent by a phisher...”可知，作者除介绍钓鱼诈骗外，还讲述了如何在网络上保护自己，故选D。 ①AI (artificial intelligence 人工智能) and machine learning refer to the ability of machines to learn and act intelligently. It means they can make decisions, finish tasks, and even tell the possible future results based on what they learn from data (数据). ②AI and machine learning already play a bigger role in everyday life than you might imagine. Health care, banking, video games, every search on the Internet you make..., all are driven by AI. ③AI is going to change almost every field of modern life. Stephen Hawking said, “Success in creating AI would be the biggest event in human history.” And Hawking added at once, “Unluckily, it might also be the last, unless we learn how to avoid the risks.” ④ ________, especially when you consider some countries are racing to develop Al-enabled autonomous weapons (人工智能自主武器). It is also going to change and take the place of many human jobs. The same worries also come from the public. According to the survey result from Centre for the Governance of AI, 91% of the people (tend to and totally)  agree that “AI is a technology that requires careful management” in Europe. ⑤But rather than agreeing with an idea of a helpless future where all human jobs are given over to robots, some people believe AI will make our working lives better. It will improve the work of humans, and new jobs will appear to take the place of the old ones. ⑥What’s more, machines become more intelligent and they are able to finish more human tasks. Things which only belong to humans like creativity and critical (批判性的) thinking, will become even more valuable in the future. ⑦Like it or not, AI is here. Maybe changing ourselves and managing it well are the best way out. Just as Benjamin Franklin once said, “When you’re finished changing, you’re finished.” 1．Which paragraph does the diagram mainly support?
