Yet teenagers look for isolation by using the device of our times — a screen, screens of all kinds. However, in whatever form, screens are addictive, and addictive from an early age. Research has shown that given the chance, six-month old babies prefer screens to real human faces. Psychologist Jean Twenge, a professor at San Diego State University, believes today’s teenagers are “on the edge” of a major mental health crisis and requests, “do anything that doesn’t connect with a screen”. The number of teenagers who really see their friends very often has dropped by more than 40% since 2000. In 2015, only 56% of 17-year-old went on a date, down from 85%. Modern teenagers are slower to learn to drive, or earn money and spend more time at home. They’re “on their phone, in their room, alone and often depressed”, she says. Some critics (评论家), however, say we should encourage our children to spend more time online. Robert Hannigan, former director of GCHQ, said in August that Britain is badly short of engineers and computer scientists, and encouraged children to develop cyber skills to compete in the digital industry. I’m not the first to say that social media is worse than real human communication, and harms mental health. Studies show teens who spend three hours a day online are 35% more likely to suicide (自杀). The suicide rate among girls aged 12 to 14 has more than doubled in a decade. 1．Why does Jean Twenge call on teens to surf online less? A．Social media is inclusive and keeps them connected. B．Social media has changed every aspect of their lives. C．Social media does great harm to their eyesight. D．Social media is addictive and leads to mental problems. 2．What may Robert Hannigan agree that we should do? A．Allow teens to isolate themselves from real social contact. B．Call on teens to do anything that doesn’t involve a screen. C．Urge children to contact people face to face instead of online. D．Encourage children to spend more time on the Internet. 3．What is the author’s attitude towards social media? A．Objective. B．Disapproving. C．Doubtful. D．Supportive. 4．What may be the best title for the text? A．Teenagers looking for isolation using screens B．Social media causing teenagers health problems C．Teenagers’ heavy addiction to social media D．Different opinions on social media use 【答题卡】1._________ 2.__________ 3.__________ 4.__________ B In today’s world, it can feel difficult to concentrate when your smartphone buzzes (嗡嗡响) every minute or two with reminders about updates, messages and much more. How can anyone get through a 500-page book when our brain is addicted to bite-sized content? Gloria Mark, professor at the University of California, has spent much of her career analysing how this affects us. She has used sensors to track attention duration on screens. When the studies started, in 2004, screen attention duration was about two-and-a-half minutes, but recently, has dropped to 47 seconds. According to Prof Mark, there were “a lot of things” that had made people more distracted. “When you switch your attention duration so rapidly, there are more errors. It takes longer to do any task and people get more stressed.” Aside from making us perform tasks less effectively, the ease with which we get distracted by one thing or another on the internet also means that we can waste time that could be spent on activities considered more worthwhile. People who have attention disorder tend to have less grey matter in brain’s parietal cortex (顶叶皮层), highlighted Nilli Lavie, professor of psychology and brain sciences at University College London. “We see greater grey matter volume in certain regions of the brain for people with a better attentional capacity,” Prof Lavie said. The good news is that while research has indicated that in today’s world we switch our attention more often than in the past, this change is not thought to have become hard-wired in our brains. “The solution is simple: first, decide to focus, then use strategies to remove distractions,” Prof Lavie said. Related to this, one strategy is to set an alarm that will go off after, for example, 20 minutes. And Prof Mark advises people to look ahead to the end of the day and to consider how they might spend time then, such as relaxing on the sofa after completing their work. “I want to feel accomplished because I’ve done my work,” she said. “That can help people stay on track.” 5．What is the main problem described in paragraph 1? A．People find it a struggle to focus. B．Bite-sized contents are addictive. C．Long passages are outdated. D．Smartphones often disturb people. 6．What can we know about the online distractions? A．They cause permanent changes to human brain. B．They have similar influences on different people. C．They increase the possibility for people to make errors. D．They offer people convenience to deal with various affairs. 7．What does Prof. Mark advise in the last paragraph? A．Set frequent alarms to take short breaks. B．Create a flexible timetable to work efficiently. C．Visualize after-work leisure time to keep daily focus. D．Seek a relaxing environment to minimize distractions. 8．What can be a suitable title for the text? A．Save Your Brain to Stay Relaxed B．Can We Reclaim Our Lost Focus? C．Why Are We Losing Concentration? D．Bite-sized Reading Ruined Our Brain 【答题卡】5.__________ 6.__________ 7.__________ 8._________ 二、完形填空（共15小题，每小题1分，满分15分） With the rapid development of the Internet, our lives have been greatly changed.

Robert Hannigan, former director of GCHQ, said in August that Britain is badly short of engineers and computer scientists, and encouraged children to develop cyber skills to compete in the digital industry.(然而，一些评论家表示，我们应该鼓励孩子多花时间上网。英国政府通信总部前主任Robert Hannigan在8月表示，英国严重缺乏工程师和计算机科学家，并鼓励孩子们培养网络技能，以便在数字行业竞争中脱颖而出)”可知，罗伯特・汉尼根会认同我们应该鼓励孩子多花时间上网。故选D。 3．推理判断题。根据第四段中“I’m not the first to say that social media is worse than real human communication, and harms mental health. Studies show teens who spend three hours a day online are 35% more likely to suicide (自杀). The suicide rate among girls aged 12 to 14 has more than doubled in a decade.(我并不是第一个指出社交媒体比现实中的人际交流更糟糕、且会损害心理健康的人。研究表明，每天上网三小时的青少年自杀的可能性要高出35%。12至14岁女孩的自杀率在十年内翻了一倍多)”可知，作者认为社交媒体危害心理健康，其态度是不赞同的。故选 B。 4．主旨大意题。根据第一段中“Research shows that isolation (隔绝) is bad for us and connected with certain diseases including depression, high blood pressure and heart disease. Yet teenagers look for isolation by using the device of our times — a screen, screens of all kinds.(研究表明，隔绝对我们有害，并与某些疾病有关，包括抑郁症、高血压和心脏病。然而，青少年却通过使用我们这个时代的设备——屏幕，各种各样的屏幕来寻求隔绝)”以及后文围绕青少年通过屏幕寻求隔绝这一现象，分别阐述了Jean Twenge、Robert Hannigan以及作者本人对此的不同看法可知，本文主要围绕“青少年利用屏幕寻求隔绝”这一现象展开讨论，A选项“Teenagers looking for isolation using screens(青少年利用屏幕寻求隔绝)”最符合文章主旨。故选A。 5．A 6．C 7．C 8．B 【导语】本文是一篇说明文。文章介绍了现代人注意力分散的现状，该问题带来的影响，以及科学应对的方法。 5．细节理解题。根据第一段“In today’s world, it can feel difficult to concentrate when your smartphone buzzes (嗡嗡响) every minute or two with reminders about updates, messages and much more. How can anyone get through a 500-page book when our brain is addicted to bite-sized content? (在当今世界，手机每隔一两分钟就会弹出更新、消息之类的提醒，嗡嗡作响，想集中注意力都难。我们的大脑都沉迷于碎片化内容了，谁还能啃得下一本500页的书呢？)”可知，该段描述人们发现集中注意力很困难的问题。故选A项。 6．细节理解题。根据第三段中“When you switch your attention duration so rapidly, there are more errors. (当你的注意力切换得如此频繁时，就更容易出现失误。)”可知，网络干扰增加了人们犯错的可能性。故选C项。 7．细节理解题。根据最后一段中“And Prof Mark advises people to look ahead to the end of the day and to consider how they might spend time then, such as relaxing on the sofa after completing their work. “I want to feel accomplished because I’ve done my work,” she said. “That can help people stay on track.” (Mark教授建议人们展望一天的结束，考虑一下他们会如何度过这段时间，比如在完成工作后躺在沙发上放松一下。“我想要成就感，因为我完成了我的工作，”她说。“这可以帮助人们保持正确的方向。”)”可知，Mark教授建议人们预想每天下班后的休闲时间，以此帮助保持专注。故选C项。 8．主旨大意题。文章聚焦注意力分散的问题，首先指出智能手机和碎片化内容导致现代人注意力持续时间缩短，再分析其负面影响，最后提出通过主动专注策略来改善注意力问题。因此，B项“我们能重拾失去的专注吗？”包含问题与希望，最适合作为文章标题。故选B项。 二、完形填空 1-5: B A A B B 6-10: C A D A C 11-15: A B A B B 解析 1.
