Looking good，feeling good Unit 4 培优提能练 A (2025·辽宁大连高一上期中) Published in the journal Sleep by Mary Carskadon at Brown University and her colleagues，a study set out to answer an age-old mystery：why do teenagers stay up so late，and why is it so hard to get them out of bed in the morning? 语篇解读　这是一篇说明文，主要介绍了一项关于青少年晚睡原因的研究，以及这一发现对学校和政策制定者的影响。 Ⅰ.主题语篇阅读 Many people believe that social forces like school pressures and partying pleasures are to blame.Carskadon，however，doubted that biological elements might be responsible.To test that guess，she surveyed 2,000 schoolchildren across the US on their preferred and actual bedtimes and their physical development，wake times，the times of day when they felt most or least active，and their physical development. The results pointed to biology.Sixth-graders(aged 11 or 12) scored higher on “eveningness” and lower on “morningness” than younger children，even though they were in the same social environment. Therefore，Carskadon and her team concluded，the practice of ringing the morning bell earlier at middle schools(for 11- to 13-year-olds) and high schools(for ages 14 to 18) than at elementary schools “may run counter to children’s biological needs”. In response，a growing number of US cities began pushing back start times in middle and high schools.In 2019，California became the first US state to pass laws supporting later start times，followed by Florida.Meanwhile，other countries，including Australia and South Korea have made similar changes. This is certainly a significant step towards improving teens’ mental and physical health.Yet later school start times alone may not be enough to stop teenagers from sleeping late.If teens stay up till dawn on their phones，or don’t have a quiet place to sleep，even a 10 am start can do little good. That is why some people argue that schools should include courses on evidence-based practices to improve sleep.In small studies，researchers at the University of Oxford have found that such courses can significantly improve sleep quality，even for children from low-income(收入) families who initially reported poor sleep. 1.What did Carskadon and her colleagues try to explore? A.The problems with existing theories. B.The effective ways to wake up teens. C.The true causes of teens’ late sleep. D.The impact of late sleep on teens’ learning. √ 细节理解题。根据第一段“Published in the journal...of bed in the morning？”可知，Carskadon及其同事的研究旨在找出青少年晚睡的真正原因。故选C。 解析 2.What does the underlined phrase “run counter to” in paragraph 3 mean? A.Go against. B.Agree with. C.Depend on. D.Focus on. √ 词义猜测题。根据上文“Sixth-graders(aged 11 or 12)...in the same social environment.”可知，Carskadon所进行的调查表明：相比于更小的孩子，六年级学生在“夜晚型”上的得分更高，在“清晨型”上的得分更低，说明他们在晚上更活跃，在早上需要睡眠。而画线词前的“the practice of ringing...at elementary schools”显然是与这一结果相悖的，所以“run counter to”在这里的意思是“与……相反”。故选A。 解析 3.What is the attitude of the authorities towards Carskadon’s conclusion? A.Disapproving. B.Doubtful. C.Favorable. D.Unconcerned. 观点态度题。根据第四段“In response，a growing number...Australia and South Korea have made similar changes.”可知，越来越多的地方开始推迟学校的上课时间，这说明官方是支持Carskadon得出的结论的。故选C。 解析 √ 4.What can be inferred from the last paragraph? A.Sleep education fails to work as expected. B.Evidence-based sleep education matters. C.Sleep education in schools is easy to improve. D.Sleep courses do little good to poor children. √ 推理判断题。根据最后一段“That is why some people argue that...initially reported poor sleep.”可知，牛津大学的研究人员已经发现基于证据的改善睡眠的课程能显著提高睡眠质量，由此可以推断出基于证据的睡眠教育对于改善青少年的睡眠质量是非常重要的。故选B。 解析 B (2025·江苏扬州高一上期中) How would you survive without your smartphone? For many of us，it’s the device we’re most attracted to—looking at it hundreds of times a day.We depend on it to perform different tasks and to connect with our friends and family.But have we become addicted to our phones? 语篇解读　这是一篇议论文。文章主要探讨了现代人对智能手机的依赖及其负面影响，旨在提醒读者注意智能手机成瘾的危害，并倡导合理使用手机，保持健康的生活方式。 Certainly，the inventor of the first mobile phone，American engineer Martin Cooper，thinks we might be.In a BBC interview，he suggested people should stop scrolling and “get a life”.But of course，once we start scrolling or watching videos，we just can’t kick the habit.Psychologist and author Jean Twenge says，“We’re all guilty of habitually checking our phones if waiting for a text or getting really into social media then kind of，looking up and realizing that an hour has passed.” There’s even a word—a phubber—to describe a person who ignores the real people around them because they are concentrating on their phones. But does it matter if we make the most of this technology? Possibly，because like a drug，the problem arises when it is taken away.A study from King’s College London found young people they studied couldn’t control the amount of time they spent on their phones.Such addictive behavior means that people become anxious or upset when they are refused constant access，which can cause anxiety and mental health issues. Interestingly，another study by the London School of Economics and Political Science suggests we don’t just look at our phones because we are encouraged by a text or an e-mail.The people they studied felt natural to interact with their phones.Professor Saadi Lahlou，co-author of the study，told the BBC，“We must learn tricks to avoid the temptation when we want to concentrate or have good social relations.” One solution could be an app that rewards students for time spent away from their phones.Another choice is changing your smartphone to an ordinary phone that has none of the distractions on it.But mainly，perhaps，we just need to look up more and reconnect with the real world! 5.What did Martin Cooper suggest people do? A.Enjoy life by stopping the habit of scrolling. B.Learn tricks to avoid the temptation. C.Change their smartphones to ordinary phones. D.Use an app that rewards them for less phone use. √ 细节理解题。根据第二段中的“In a BBC interview，he suggested people should stop scrolling and ‘get a life’.”可知，Martin Cooper建议人们通过停止滚屏的习惯来享受生活。故选A。 解析 6.Why do people feel ashamed after checking their phones? A.For not being productive enough. B.For missing important texts or calls. C.For not being able to connect with others. D.For wasting too much time uncontrollably. √ 细节理解题。根据第二段中的“But of course，once we start scrolling or...’We’re all guilty of habitually checking our phones...and realizing that an hour has passed.’”可知，人们在使用手机后会感到羞愧是因为意识到自己浪费了大量时间。故选D。 解析 7.What does the study from King’s College London imply? A.The young shouldn’t use their phones. B.Curing phone addiction is not an easy job. C.Young people can’t survive without phones. D.Using phones leads the young to be anxious. √ 细节理解题。根据第三段中的“A study from King’s College...cause anxiety and mental health issues.”可知，这项研究暗示使用手机会让年轻人感到焦虑。故选D。 解析 8.What is the main message of the text? A.Smartphones are essential for modern life. B.People should avoid their addiction to smartphones. C.The inventor of the mobile phone should be punished. D.Smartphones have a certain impact on mental health. 主旨大意题。通读全文可知，文章主要探讨了现代人对智能手机的依赖及其负面影响，旨在提醒读者注意智能手机成瘾的危害，避免对智能手机上瘾。故选B。 解析 √ (2025·江苏扬州高一上期中) Ma Mian Qun，also 1.
