Section Ⅰ　Starting out & Understanding ideas Part Ⅰ　Reading comprehension 第一步　课前导入•激趣启思 1.Look at the title of the passage and the picture． Predict what the passage is about． ①Maybe it’s about why people should take a break from social media． ②It might talk about the problems of using social media too much． ③I think it’s about someone who quit social media and felt happier． ④Probably about how to reduce screen time and live a healthier life． ⑤Maybe it gives tips on how to stay away from phones and social apps． 2.Now read the moderator’s words in the textbook and check your prediction． It is about an activity called Social Media Detox， in which students joined and shared their experiences about giving up using phones． 第二步　速读课文•理清脉络 Skim the passage and fill in the blanks． 第三步　精读课文•领悟细节 Task 1：Read the passage carefully and choose the best answers． 1.What has Anna realised now？（　　） A．The detox is more important than anything else． B．She had wasted too much time checking the phone． C．She realised the value of real contact． D．She almost knows nothing about what she has done． 2.What did Devon learn from the activity of the detox？（　　） A．The need to use social media for teens． B．The negative effects of social media on teens． C．The importance of communicating face to face． D．The ability of memorizing things of the Internet． 3.How did George survive the seven days？（　　） A．To avoid giving in．　 B．To check the phone． C．To turn to his brother．　 D．To attend the sports． 4.What made Max feel embarrassed？（　　） A．Failing to attend the party． B．Forgetting the place for the party． C．Missing out the latest news． D．Failing at the beginning of the detox． 答案：1－4　BCDD Task 2：Think creatively and critically and answer the questions． 1.What do you think of the Social Media Detox？ Why？ It is worthwhile for teens to have a try， because it will make them spend less time online and have more real contact in life． 2.Why do some people feel like losing an arm if not using social media？ Because they rely on social media to communicate with others too much． 第四步　课文融通•学以致用 　　根据课文内容，在空白处填入1个适当的单词或括号内单词的正确形式。 　　Five students shared their experiences and reflections after the Social Media Detox．For Anna， the detox is so difficult 1.that she just lasted two days．But she realised that too much of her time 2.had been occupied （occupy） with checking her phone．She is trying to spend more time 3.picking （pick） up her hobbies．Because of four days’ detox， Devon felt 4.it strange not to know how his classmate spent the weekend． However， by talking about their 5.profiles （profile）， he was aware of the value of real contact． Cindy and George 6.managed （manage） the whole week．Cindy felt she was missing out at first， but four days later， she didn’t feel like that．George did the detox 7.easily （easy）， but he did give his phone to his dad 8.to avoid （avoid） giving in． He had physical exercise with his brother， which left him 9.tired （tire） out but healthier． Max failed on the first day because he had to rely 10.on his phone to check where a party was． And it took him too much time to catch up on news． SOCIAL MEDIA DETOX 　　Moderator 　　Today marks the last day of the Social Media Detox， Brenton High’s fundraising campaign① for new sports equipment．At the start of the detox， over 100 students had been persuaded to② stop using social media， in ANY form， for seven days．This meant no messaging friends， no posting photos， no blogging — nothing．They had been promised money by family and friends for each day ［1］spent without using social media．They were excited．They were nervous．But could they do it？ 　　［2］With the detox now finished， they’ve switched on their devices③ and they’re back online．［3］I bet you’re as eager as I am to④ find out just how many have been motivated enough to⑤ last the full seven days! And what， if anything⑥， has been learnt from the experience？ 　　Anna 17 　　I lasted two days．The detox was more difficult to tolerate ［4］than I had expected． I felt like⑦［5］ I had lost an arm! ［6］ Not eating for two days would have been easier! But on reflection⑧， I can see how much of my time had been occupied with⑨ checking my phone． I’m now trying to spend less time online and more time picking up my hobbies． 　　【释疑难】　［1］过去分词短语作后置定语，修饰名词短语each day。 　　［2］with复合结构，过去分词finished作宾语补足语。 　　［4］than引导比较状语从句。 　　［5］本句使用了虚拟语气，表示和过去的事实相反。 　　［6］动词－ing形式的否定式在句中作主语。 【赏靓点】　［3］句中I bet ．．．口语色彩浓厚，拉近了与读者的距离。as eager as I am结构表达了主持人和读者同样急切的心情，有效地设置了悬念，激发读者的阅读兴趣。 Paras.1－3 1.语块翻译 ①筹款活动 ②被说服做…… ③打开他们的设备 ④渴望做…… ⑤有足够动力做…… ⑥如果真有什么的话 ⑦感觉像 ⑧经再三考虑 ⑨忙于…… 2.熟词生义 （1）detox （Title） 熟义：n．排毒（疗法） 文中义：n．戒瘾，此处指“数字排毒”，即在此期间不使用电子设备。 （2）last （Para.2） 熟义：adj．最后的 文中义：v．维持；坚持 　　Devon 16 　　I lasted four days．On Monday， my classmate and I spoke about ［7］what we did at the weekend — it felt really strange not to already know ［8］what he had done． We would usually have posted pictures and updated our profiles⑩． ［9］Doing the detox meant we had to talk and explain what we were doing and thinking!It made me realise the value of real contact⑪［10］ that I had forgotten． 　　Cindy 18 　　I managed the whole week! At first， I really felt I was missing out⑫． Then， instead of messaging my friend， I went round⑬ to her house． ［11］ Without our phones， we had a proper conversation for over two hours， without being distracted by⑭ messages from other people． It felt so good! Then I decided to visit a different friend every day． By the fifth day， I wondered — was I really missing out by not constantly checking my phone ［12］to see what everyone else was up to⑮？ 　　George 16 　　I did all seven days， too! To be honest⑯， I didn’t find the detox too difficult， but I did give my phone to my dad to avoid giving in⑰! My brother thought I should make full use of⑱ the time without my phone， so he took me to check out⑲ our local sports centre．An hour’s sport each day left me tired out⑳ and wanting to go to bed early．The detox made me healthier! 　　【释疑难】　［7］what引导宾语从句，作介词about的宾语。 　　［8］what引导宾语从句，作动词know的宾语。 　　［9］动词－ing短语Doing the detox作主语；we had ．．． thinking为宾语从句，从句省略了连接词that；what引导宾语从句，作动词explain的宾语。 　　［10］that引导定语从句，修饰先行词contact。 　　［12］动词不定式短语作目的状语；其中，what引导宾语从句，作动词see的宾语。 【赏靓点】　［11］句中两个without介词短语前后呼应。前一个without表示条件，后一个without表示结果（不受干扰的状态），强调了脱离手机后，人与人之间的交流回归了纯粹和专注。 Paras.4－6 1.语块翻译 ⑩更新我们的个人资料/动态 ⑪ 意识到真正沟通的重要性 ⑫ 错过；遗漏，漏掉 ⑬ 拜访；（消息、谣言等）流传，传播 ⑭ 被……分心/干扰 ⑮ 正在做；从事 ⑯ 说实话，老实说 ⑰ 认输；屈从；让步 ⑱ 充分利用 ⑲ 查看；调查 ⑳ 筋疲力尽 2.靓词 distract （Para.5） 赏析：distract在文中指被不断的提示音转移注意力，点出了社交媒体对深层沟通的破坏。 　　Max 17 　　I’m embarrassed to say that I threw in the towel on the first day㉑! I knew there was a party ［13］happening that evening， but without access to social media㉒ I couldn’t remember ［14］where it was! In the end， I turned on my phone to check， but couldn’t resist having a quick look at㉓ my social media accounts． What’s worse㉔， I then spent so much time catching up on㉕ news， I almost missed the party! 　　Moderator 　　The detox raised a total of㉖ ￡1，632.82 for new school sports equipment! Well done， everyone ［15］ who took part! After reading the posts on this forum， it seems that something other than㉗ money has also been raised through the detox． ［16］Awareness of just how much we rely on㉘ social media can help us step away from㉙ it and communicate with each other better． 　　【释疑难】　［13］动词－ing短语作后置定语，修饰名词party。 　　［14］ where引导宾语从句，作动词remember的宾语。 　　［15］ who引导定语从句，修饰先行词everyone。 　　【赏靓点】　 ［16］句是全文的主旨升华。主语是Awareness of ．．． social media，谓语是can help。Moderator不仅总结了活动筹款的成果，更指出了活动深层的教育意义：只有意识到依赖（rely on），才能主动抽离（step away），从而改善人际关系。 Paras.7－8 1.语块翻译 ㉑在第一天 ㉒使用社交媒体的机会 ㉓快速查看 ㉔更糟糕的是 ㉕补上；了解（最新情况） ㉖总共，总计 ㉗除了……以外 ㉘依靠，依赖 ㉙远离 2.靓词 throw in the towel （Para.7） 赏析：这是一个源自拳击比赛的习语（拳击手扔毛巾表示认输）。Max用它来幽默地形容自己无法坚持“戒断”挑战，形象地承认了自己的失败。 参考译文 社交媒体脱瘾 　　主持人 　　布伦顿高中为给购置新的体育设备筹款，举办了一项名为“社交媒体脱瘾”的活动。今天是活动的最后一天。脱瘾活动初期，我们成功说服100多名学生连续七天不得使用任何形式的社交媒体。这就意味着他们在这段时间内不能给朋友发短信，不能上传照片，不能发博客，与社交媒体相关的任何形式的活动都不行。脱离社交媒体的每一天，他们都能收到来自家人和朋友的奖励金。对此，他们很兴奋，也很紧张。但他们真的能做到吗？ 　　如今，脱瘾活动已结束，他们纷纷开启电子设备，重返网络。相信你和我一样，迫切想知道多少人有足够的动力坚持了整整七天!而他们，又从此次经历中学到了什么？ 　　安娜　17岁 　　我坚持了两天。社交媒体脱瘾比我预期的更加难以忍受。没了社交媒体，就像缺少一只胳膊一般。让我饿两天可能还更轻松些!但一番反思后，我也意识到平日花在看手机上的时间太多了。现在，我正试图减少上网时间，把更多精力用于重拾自己的爱好。 　　德文　16岁 我坚持了四天。周一，我和同学讨论了周末各自的活动——我并不知道他都做了些什么，这感觉太奇怪了。因为平时我们都会上传照片，更新各自的动态。参与这次脱瘾活动，意味着我们不得不互相交流并向对方解释自己的所做所想。这也让我意识到已经遗忘了的真正沟通的重要性。 　　辛迪　18岁 　　我坚持了整整一周!最初，我真的感觉自己错过了无数消息。但我忍住没给朋友发消息，而是直接去了她家。没有手机的我们，好好地聊了两个多小时，没有被其他人的消息干扰，这感觉真棒!接下来我决定每天去见一位不同的朋友。到第五天时我在想，当我不再忙于查看手机关注他人生活的时候，我真的错过了很多吗？ 　　乔治　16岁 　　我也坚持了整整七天!说实话，我觉得社交媒体脱瘾没那么难，但为了让自己不要半途而废，我还是把手机上交给爸爸了。哥哥认为我应该充分利用没有手机的日子，因此他带我去了我们当地的体育中心。每天一小时的运动让人筋疲力尽，想早点上床休息。脱瘾活动让我更健康了! 　　马克斯　17岁 　　我都不好意思说自己第一天就打了退堂鼓。脱瘾活动开始的当晚有个聚会，但如果不靠社交媒体的话，我怎么也想不起地点在哪儿!最后我还是打开手机查看了一下，结果没忍住，偷看了一眼我的社交媒体账户。更糟的是，我花了大把时间刷新动态，差点错过了本该要去的聚会! 　　主持人 　　此次脱瘾活动总共为学校筹集了1，632.82英镑，用于购置新的体育设备!每位参与者都做得很棒!看了论坛上的各个帖子，这次活动对人们的影响似乎远远不止活动筹集到的钱。脱瘾活动还让我们意识到自己对社交媒体的依赖程度，从而帮助我们摆脱它的束缚，更好地互相沟通。 Part Ⅱ　Language points Ⅰ．阅读词汇 1.the moderator of the meeting这次会议的主持人

activities， including a new job， a research position， university courses， gym sessions， and guitar practice．Sometimes it felt like too much to balance all these activities， and I was eager for some quiet time alone．However， a remarkable change occurred when I decided to start waking up at 5：30 am． 　　At first， it was incredibly challenging and made me quite unhappy．I frequently turned off the alarm clock， causing me to miss buses and trains， leading to tardiness at work and subsequent issues．But then， I laid my eyes on a book titled “Morning Miracle”， which motivated me to rise 30 minutes earlier． 　　I adopted a straightforward routine： spending five minutes journaling， sipping water slowly， taking deep breaths to unwind， doing a few push－ups， and glancing at a board displaying my goals．After persevering for 21 days， my job performance improved dramatically．I felt more focused and energetic， and this wasn’t just because I thought it would． 　　The quiet morning helps me focus on my tasks．I learned to do one thing at a time．And this saved me from getting mentally exhausted．I also started my day by thinking about the good things and writing down what I’m grateful for to manage stress． 　　Next， I prioritized （优先处理） my tasks depending on how important they are， ensuring that I addressed the most crucial ones first．I also made sure to take breaks during the day to recharge．I also set aside time for learning and self－improvement， aiming to advance in my career by gaining new skills and knowledge． 　　To maintain this morning routine， I ensured that I was in bed by 10 pm， allowing me to start my day at 5：30 am．This habit uses the peaceful mornings to enhance my physical， mental， and emotional well－being．However， I managed to overcome these difficulties．By making these adjustments， I found a newfound balance in my busy life as a university student． 语篇解读：本文是一篇记叙文。文章主要讲述了作者通过早起改变自己的作息时间，从而使自己的生活、学习都发生了很大的变化，健康状况也得到了较大的提升，作者也因此在繁忙的大学生活中找到了新的平衡。 1.What problem did the

（炎症） with a new study that shows this connection may grow stronger over time． 　　The results， published in The Journal of Medical Internet Research， showed that not only was more time on social media linked to higher levels of inflammation at one moment， but it also predicted increased inflammation five weeks later． “This shows the effect may last，” says David Lee， who led the study． 　　There are two types of inflammation． The first is acute inflammation like redness around a cut or swelling after a sprained ankle． It’s the body’s normal way of healing from injury or infection． The second type is chronic inflammation， which lasts longer and has been tied to serious health problems such as heart disease， cancer， diabetes， and mental health issues． Unlike acute inflammation， chronic inflammation can be caused by everyday factors such as stress， loneliness， poor diet， lack of sleep， and not exercising enough． 　　Lee’s research focuses on this long－term type of inflammation． The study provides the first longitudinal （纵向的） evidence that social media use over an extended time period is possibly responsible for increased inflammation． Moreover， it assesses the effects of social media use， as measured objectively by a screen－time app rather than formerly relying on participants’ memory of how much time they spent on social media． 　　The research team hired 171 young adults for the study and measured their C－reactive protein levels — a marker of inflammation — at the start and again after five weeks． During that time， the app recorded their daily screen use． 　　While the rise in inflammation doesn’t cause any immediate health issues， Lee warns that early signs of inflammation in young people could predict the onset of disease later in life． “The relation between social media use and inflammation opens up new questions for future studies，” he says， “Now we need to go deeper than just screen time． We should try to understand how and why using social media affects our health．” 语篇解读：本文是一篇说明文。文章主要介绍了科学家David Lee的研究，揭示了长期使用社交媒体与慢性炎症水平升高的关联及其潜在健康风险。 5.What does the new study suggest about social media use？（　　） A．It helps reduce stress and loneliness． B．It causes immediate health problems． C．It raises inflammation levels over time． D．It reduces chronic inflammation in youth． 解析：C　细节理解题。 根据第一段和第二段内容可知，研究表明随着时间推移，社交媒体使用会提高炎症水平。 6.What does the underlined word “acute” in paragraph 3 mean？（　　） A．Lasting and mild． B．Instant and sudden． C．Deadly and severe． D．Mild and temporary． 解析：B　词义猜测题。 根据第三段内容可知，文中将acute inflammation与持续时间更长的chronic inflammation进行对比，前者举例为伤口红肿等短期愈合过程。由此推断，acute 意为“急性的”。 7.What makes Lee’s research different from previous studies？（　　） A．Its way to collect data． B．Its use of various data． C．Its interviewing method． D．Its focus on young adults． 解析：A　推理判断题。 根据第四段中的Moreover， it assesses the effects ．．．they spent on social media．可知，李的研究与以前研究的不同之处在于使用了客观的应用程序记录数据，而非依赖参与者的主观记忆。 8.What does the last paragraph say about the study？（　　） A．Its technical limitations． B．Its data collection process． C．Its immediate health impacts． D．Its future research directions． 解析：D　推理判断题。 根据最后一段中的The relation between social media use ．．． future studies可知，最后一段主要讨论了该项研究在未来需要进一步探讨的方向。 C 　　In modern society， the issue of whether students should be allowed to use mobile phones in school has sparked widespread debate．Some people believe that mobile phones can enhance learning efficiency and communication， while others argue that they may cause distractions and negative impacts on students’ studies． 　　Those in favor of students using mobile phones in school claim that with the development of educational apps， students can access a wealth of learning resources anytime and anywhere．For example， they can use language learning apps to practice listening and speaking skills， or search for relevant information to supplement classroom knowledge．In addition， mobile phones also provide a convenient way for students to communicate with teachers and classmates， which is conducive to the exchange of learning experiences and the discussion of problems． 　　However， opponents hold that mobile phones are a major source of distraction for students．With the various functions and entertainment apps on mobile phones， students are easily attracted and may waste a lot of time on them during class or study time．This will not only reduce learning efficiency but also affect their concentration and academic performance．Moreover， the use of mobile phones may also lead to problems such as cheating in exams and the spread of negative information， which is not conducive to the construction of a good school atmosphere． 　　In my opinion， although mobile phones have certain advantages in learning， the negative impacts cannot be ignored．Therefore， schools should formulate reasonable regulations to guide students to use mobile phones correctly．For example， schools can allow students to use mobile phones at specific times and places under the supervision of teachers， or restrict the use of some entertainment apps to ensure that mobile phones play a positive role in students’ learning and life． 语篇解读：本文是一篇议论文。文章论述了学生将手机带进学校的好处和弊端，并提出了学校应该制定合理的规定来规范学生使用手机的行为。 9.What is one of the reasons why some people support students using mobile phones in school？（　　） A．Mobile phones can help students

语篇解读：本文是一篇说明文。文章探讨了在信息过载时代如何平衡资讯获取与心理健康，并提出了建立健康新闻消费习惯的具体策略。 13.G　上文指出持续的头条新闻，尤其是令人不安的消息，有时会让人不堪重负；下文提出在获取信息和保持心理健康之间找到平衡至关重要。G项（接触令人不安的新闻报道可能导致焦虑和情绪衰竭）承接了上文对负面新闻影响的描述，并为下文强调心理平衡的必要性提供了逻辑依据。 14.A　上文给出了“新闻疲劳”的定义，即因消费过量负面报道而感到情绪疲惫；下文列举了焦虑加剧、情绪麻木和注意力不集中等具体表现。A项（这种状态会导致明显的后果）起到了承上启下的作用，引出下文对各项后果的阐述。A项中的“这种状态”指代上文的新闻疲劳。 15.F　上文建议选择可靠的媒体而非耸人听闻的标题；下文建议跳过那些只会增加压力而无实质信息的报道。F项（关注直接影响你或符合你兴趣的新闻）提出了另一条具体可行的消费策略，与上下文的建议构成并列关系，共同论证如何进行健康的新闻消费。 16.C　上文列举了志愿服务、捐款或传播意识等具体的积极应对行动。C项（这些积极的回应有助于减少无助感）点明了上文提到的具体行为能带来的心理益处，符合语境。 17.D　空处为段落主题句。下文建议关注致力于分享善举、科学突破或社区成就的社交媒体账号。D项（转向积极的新闻来源有助于平衡负面新闻的影响）精准概括了本段主旨，其中“积极的新闻来源”与下文提到的善举和突破等正面内容高度呼应。 1 / 2 学科网（北京）股份有限公司 $
