Social networking sites have become virtual extensions of the school hallways, so would you add your parents as “friends” and allow them to view your online activities and conversations with friends? In the past the generation gap included a technology gap, where children were up to date with the latest technology and parents were left behind, content to continue their day-to-day lives as they always had because they had no need to be tech-savvy(精通技术的). However, more and more parents are beginning to realize just how important social networks are in their lives. This realization has given many parents the motivation to educate themselves about social networking sites. These days many people are attracted to social networking sites because they can choose who they have around them; there’s also a certain amount of control over privacy that we don’t get in real life. Sometimes we feel that privacy is disturbed when we must accept a “friend” request from a parent or family member. It’s a difficult choice whether or not to allow a parent to become a part of our online lives. On the one hand we don’t want to “reject” their request because that might hurt their feelings or make them feel you have something to hide. On the other hand, if you do accept, then you could have a sense of being watched and no longer feel free to comment or communicate the way you did before. A recent survey suggested that parents shouldn’t take it to heart if their child ignores their request: “When a teen ignores a parent’s friend request, it doesn’t necessarily mean that they are hiding something, but it could mean that this is one part of their life where they want to exert their independence.” Perhaps talking with parents and giving explanations would help soften the blow when you do choose not to add them to your friends list. 1. Why do many parents want to learn about social networking sites? A. Because they are eager to explore technologies. B. Because they are bored with their daily life. C. Because they want to watch their children. D. Because they realize the importance of the sites. 2. What might be the reason for teens to reject their parents’ friend request? A. They have nothing to hide. B. Their privacy cannot be guaranteed. C. They don’t want to teach their parents. D. They can’t choose friends around them. 3. What can be a suitable title for the text? A. To Friend or Not to Friend Parents B. To Prevent Privacy from Parents C. Setting Boundaries Online D. Bridging the Tech Generation Gap 4. What is most likely to be talked about next? A. How to bridge the generation gap. B. How to make friends on social networks. C. How to explain to parents about the rejection. D. How to use the social networking sites wisely. B Online short-form video has shifted from a casual entertainment to a constant background in many children’s lives. What used to fill a spare moment now shapes how young people relax, communicate, and form opinions, with short-form video platforms drawing in hundreds of millions of under-18s through endlessly personalized feeds. Offering quick routes to humour, trends and connection, these platforms encourage long sessions of rapid scrolling(滑动) that can be difficult for young users to manage. They were never built with children in mind, although many children use them daily and often alone. Problematic use is less about minutes spent and more about patterns where scrolling becomes hard to stop. Short-form videos (typically between 15 and 90 seconds) are engineered to capture the brain’s desire for novelty. Each scrolling promises something different. Because the feed rarely pauses, the natural breaks that help attention reset disappear. Over time, this can affect children’s mood, attention, schoolwork and relationships. Sleep is one of the clearest areas where short-form video can take a toll. Many children view screens when they should be sleeping. The bright light delays the release of melatonin(褪黑激素), which helps regulate sleep, making it harder for them to fall asleep. And the emotional highs and lows of rapid content make it particularly difficult for the brain to settle. These sleep disturbances affect mood, emotional stability and memory. Exposure to material children never intended to see adds risk. Because short videos appear instantly and autoplay, children can be shown violent footage(画面) or harmful challenges before they have time to look away. Unlike longer videos, short-form content provides almost no warning or emotional preparation. A single scrolling can produce a sudden shift from silly to disturbing. New guidelines encourage schools to integrate online safety into courses. At home, open conversation and simple routines like keeping devices out of bedrooms can help. Short-form videos can be creative and comforting. With thoughtful support, children can enjoy them without harming wellbeing. 5. How do short-form video platforms attract so many kids? A. Through continuous amusement-focused content. B. Through constantly tailored information streams. C. By interacting with kids through their videos. D. By building special backgrounds in kids’ mind. 6. What’s the root cause of children’s improper use of short videos? A. The duration of short videos. B. The brain’s appetite for novelty. C. The hard-to-stop scrolling patterns. D. The pauses between short videos. 7. What does the underlined phrase “take a toll” in paragraph 4 probably mean? A. Have a long-term effect. B. Cause noticeable harm. C. Provide a form of relief. D. Lead to financial cost. 8. What can be inferred from the passage? A. Kids can have big mood changes between two scrolls. B. Online safety should be a required course in the school. C. Kids prefer long-form entertainment videos to short ones. D. Melatonin causes sleeplessness problems to a great degree. 七选五 In this digital age, the Internet is really a necessary part of everyday life. And because we communicate with others online so much, it's especially important to be aware of digital etiquette (礼仪). Etiquette is a basic set of rules for polite behaviour online. 1 . Keep things respectful, truthful and kind When you're commenting, posting or sending a message on the Internet, remember that you're interacting(互动) with actual people who have feelings and are worthy of respect. 2 . This means never using unkind or disrespectful language when communicating with others online. Review messages, comments and posts before sending In the heat of the moment, it's easy to type something rude or negative and hit "post". 3 . And you'll often end up regretting it later. To prevent such regret, stop and think carefully before posting or sending something. Rewrite what you've written and make sure it's truthful, respectful and fair. 4 . When you post something publicly on the Internet, strangers now have access to that information. To keep yourself safe, don't post personal information (such as your full name, where you live, where you go to school, where you work, etc.).Respect others and don't post their personal information without permission (允许), as well. Don't send unsuitable content to others 5 . If you wouldn't feel comfortable showing something to someone in person, don't send it online. Unsuitable content can harm relationships, damage reputations(名誉) and even lead to legal issues. Once shared, such content can spread quickly and be difficult to control. A. Stay on topic when posting or commenting B. Protect your privacy and the privacy of others C. Show appreciation to others' personal information D. Unfortunately, this often leads to hurting others' feelings E. It's important not to share improper photos, videos or links with others F. Always remember to treat people the way you would want to be treated G.

He had anticipated what would happen and worked out a solution in advance. (用分词作状语改写) ________________________________________________________________ 【答案】Having anticipated what would happen, he worked out a solution in advance. 【详解】考查非谓语动词。句意：他已预料到会发生什么，并提前想出了解决方案。改写后的句子可用he worked out a solution in advance作句子主干，将had anticipated what would happen改写之后作状语，根据原句中had anticipated可知，anticipate“预料”这一动作发生在worked out之前，改写时需用现在分词的完成式having anticipated体现这一时间顺序，句首单词，首字母大写。故填：Having anticipated what would happen, he worked out a solution in advance. 9. Luckily, I was selected to take part in an activity on behalf of my classmates. (同义替换) →Luckily, I was selected to take part in an activity ________________ my classmates. 【答案】representing 【详解】考查非谓语动词。句意：幸运的是，我被选中代表我的同学参加一个活动。分析原句可知 “on behalf of”的含义，它表示“代表”。根据题目要求进行同义替换，在英语中“represent”有“代表”的意思，这里需要用它的非谓语形式来替换原短语。因为句子中已经有了谓语动词“was selected”，“代表同学们”这个动作和句子主语“I”之间是主动关系，所以要用现在分词形式“representing”作后置定语修饰activity。故填representing。 10. Because he focused on the class, he understood what the teacher stressed. (用动词-ing形式作状语改写) ________________________________________________________________ 【答案】Focusing on the class, he understood what the teacher stressed. 【详解】考查非谓语动词。原句句意：因为他专注于课堂，所以他理解老师所强调的内容。原句中Because引导原因状语从句，结合所给要求可知，可将这部分改为非谓语作原因状语，focus on“专注于”和he逻辑上是主动关系，因此用focus的现在分词形式。故答案为：Focusing on the class, he understood what the teacher stressed. 结合中文提示用动词-ing补全句子 　　On the way home from work, Li Ming suddenly 1.________________(发现一个老人躺在路边) .2.________________(了解到老人不小心受伤后), Li Ming immediately contacted his family and called 120.Soon an ambulance arrived and carried the old man and Li Ming to the nearest hospital.About ten minutes later, the old man’s son 3.________________(住在附近社区) got to the hospital and expressed great thanks to Li Ming.4.________________(虽然到家晚了), Li Ming felt it was worth it.  【答案】 1. found an old man lying by the roadside 2.

(然而，越来越多的父母开始意识到社交网络在他们生活中的重要性。这种认识给了许多父母了解社交网站的动力。)”可知，许多父母想要了解社交网站是因为他们意识到了社交网站的重要性。故选D项。 2. 推理判断题。根据第三段“These days many people are attracted to social networking sites because they can choose who they have around them; there’s also a certain amount of control over privacy that we don’t get in real life. Sometimes we feel that privacy is disturbed when we must accept a “friend” request from a parent or family member. (如今，许多人被社交网站所吸引，因为他们可以选择身边的人；在现实生活中我们得不到这样的隐私控制。有时，当我们必须接受父母或家人的“好友”请求时，我们会觉得隐私受到了干扰。)”可知，青少年可能会拒绝父母的好友请求是因为他们觉得隐私无法得到保证。故选B项。 3. 主旨大意题。根据第一段“Social networking sites have become virtual extensions of the school hallways, so would you add your parents as “friends” and allow them to view your online activities and conversations with friends? (社交网站已经成为学校走廊的虚拟延伸，那么你会把父母加为“好友”，让他们查看你的在线活动和与朋友的对话吗？)”以及下文对是否应该添加父母为好友的讨论可知，文章主要讨论了青少年在社交网络上是否应该添加父母为好友的问题。因此，A项“To Friend or Not to Friend Parents (是否加父母为好友)”最符合文章主旨，适合作标题。故选A项。 4. 推理判断题。根据最后一段“Perhaps talking with parents and giving explanations would help soften the blow when you do choose not to add them to your friends list. (也许当你选择不将父母添加到好友列表时，与他们交谈并给出解释会有助于减轻打击。)”可知，文章接下来可能会讨论如何向父母解释拒绝添加他们为好友的原因。故选C项。 B Online short-form video has shifted from a casual entertainment to a constant background in many children’s lives. What used to fill a spare moment now shapes how young people relax, communicate, and form opinions, with short-form video platforms drawing in hundreds of millions of under-18s through endlessly personalized feeds. Offering quick routes to humour, trends and connection, these platforms encourage long sessions of rapid scrolling(滑动) that can be difficult for young users to manage. They were never built with children in mind, although many children use them daily and often alone. Problematic use is less about minutes spent and more about patterns where scrolling becomes hard to stop. Short-form videos (typically between 15 and 90 seconds) are engineered to capture the brain’s desire for novelty. Each scrolling promises something different. Because the feed rarely pauses, the natural breaks that help attention reset disappear. Over time, this can affect children’s mood, attention, schoolwork and relationships. Sleep is one of the clearest areas where short-form video can take a toll. Many children view screens when they should be sleeping. The bright light delays the release of melatonin(褪黑激素), which helps regulate sleep, making it harder for them to fall asleep. And the emotional highs and lows of rapid content make it particularly difficult for the brain to settle. These sleep disturbances affect mood, emotional stability and memory. Exposure to material children never intended to see adds risk. Because short videos appear instantly and autoplay, children can be shown violent footage(画面) or harmful challenges before they have time to look away. Unlike longer videos, short-form content provides almost no warning or emotional preparation. A single scrolling can produce a sudden shift from silly to disturbing. New guidelines encourage schools to integrate online safety into courses. At home, open conversation and simple routines like keeping devices out of bedrooms can help. Short-form videos can be creative and comforting. With thoughtful support, children can enjoy them without harming wellbeing. 5. How do short-form video platforms attract so many kids? A. Through continuous amusement-focused content. B. Through constantly tailored information streams. C. By interacting with kids through their videos. D. By building special backgrounds in kids’ mind. 6. What’s the root cause of children’s improper use of short videos? A. The duration of short videos. B. The brain’s appetite for novelty. C. The hard-to-stop scrolling patterns. D. The pauses between short videos. 7. What does the underlined phrase “take a toll” in paragraph 4 probably mean? A. Have a long-term effect. B. Cause noticeable harm. C. Provide a form of relief. D. Lead to financial cost. 8. What can be inferred from the passage? A. Kids can have big mood changes between two scrolls. B. Online safety should be a required course in the school. C. Kids prefer long-form entertainment videos to short ones. D. Melatonin causes sleeplessness problems to a great degree. 【答案】5. B 6. B 7. B 8. A 【导语】本文是一篇说明文。文章主要讲述了短视频平台通过个性化推送吸引大量儿童，不当使用影响儿童身心健康及应对措施。 5. 细节理解题。根据第一段中“What used to fill a spare moment now shapes how young people relax, communicate, and form opinions, with short-form video platforms drawing in hundreds of millions of under-18s through endlessly personalized feeds.(过去那些闲暇时间里用来消遣的事情，如今已成为年轻人放松、交流和形成观点的方式，而短视频平台凭借其个性化十足的内容推送，吸引了数亿年龄在18岁以下的用户)”可知，短视频平台通过持续定制化的信息流吸引孩子。故选B。 6. 细节理解题。根据第三段中“Problematic use is less about minutes spent and more about patterns where scrolling becomes hard to stop. Short-form videos (typically between 15 and 90 seconds) are engineered to capture the brain’s desire for novelty.(不当使用与其说是时长问题，不如说是滑到停不下来的使用模式。短视频(通常15到90秒)被设计成迎合大脑对新鲜感的追求)”可知，儿童不当使用短视频的根本原因是大脑对新奇事物的渴望。故选B。 7. 词句猜测题。根据第四段中“Sleep is one of the clearest areas where short-form video can take a toll. Many children view screens when they should be sleeping. The bright light delays the release of melatonin (褪黑激素), which helps regulate sleep, making it harder for them to fall asleep. And the emotional highs and lows of rapid content make it particularly difficult for the brain to settle. These sleep disturbances affect mood, emotional stability and memory.(睡眠是短视频take a toll最突出的领域之一。很多孩子在本该睡觉的时间看屏幕。明亮的光线会延迟帮助调节睡眠的褪黑素分泌，让他们更难入睡。而快速切换内容带来的情绪起伏，会让大脑尤其难以平静。这些睡眠问题会影响情绪、情绪稳定性和记忆力)”可知，本段主要讲的是睡眠是短视频对儿童产生不良影响最明显的领域之一，即睡眠是短视频可以造成明显伤害的最明显的领域之一，故take a toll意思是“造成明显伤害”。故选B。 8. 推理判断题。根据倒数第二段中“Because short videos appear instantly and autoplay, children can be shown violent footage (画面) or harmful challenges before they have time to look away. Unlike longer videos, short-form content provides almost no warning or emotional preparation. A single scrolling can produce a sudden shift from silly to disturbing.(因为短视频会立刻出现并自动播放，孩子可能还没来得及移开目光，就看到暴力画面或有害挑战。与长视频不同，短视频几乎不提供任何预警或心理准备。轻轻一划，内容就可能从搞笑突然变成令人不安)”可推知，孩子们在两次划动之间可能会有很大的情绪变化。故选A。 七选五 In this digital age, the Internet is really a necessary part of everyday life.
