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。

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． 1.What problem did the author face before changing his wake－up time？（　　） A．Lack of sleep．　 　 B．Lack of motivation． C．Poor study performance．　 　 D．An imbalance in activities． 2.What does the underlined word “tardiness” in paragraph 2 probably mean？（　　） A．Lateness．　 　B．Tiredness． C．Progress．　 　D．Efficiency． 3.On what basis did the author prioritize tasks？（　　） A．Difficulty．　 　B．Importance． C．Complexity．　 　D．Availability． 4.What is the main purpose of the text？（　　） A．To explain the importance of waking up early． B．To recommend a book called “Morning Miracle”． C．To share how the author found balance in his life． D．To describe the author’s busy life as a university student． B 　　（2026•湖北随州期中）A scientist from the University at Buffalo has built on earlier research linking social media use to inflammation （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．” 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． 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． 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． 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． 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． 9.What is one of the reasons why some people support students using mobile phones in school？（　　） A．Mobile phones can help students relax．　 　 B．Mobile phones can replace teachers． C．Mobile phones can provide learning resources．　 　 D．Mobile phones can make students more popular． 10.Why do some people oppose students using mobile phones in school？（　　） A．Because mobile phones are too expensive． B．Because mobile phones are not necessary for students． C．Because mobile phones may cause distractions． D．Because mobile phones are difficult to operate． 11.What’s the author’s attitude towards students using mobile phones in school？（　　） A．Supportive．　 　B．Opposed． C．Neutral．　 　D．Indifferent． 12.What is the main topic of this passage？（　　） A．The advantages of mobile phones． B．The disadvantages of mobile phones． C．Whether students should use mobile phones in school． D．The impact of mobile phones on society． Ⅱ．阅读七选五 　　（2026•福建福州期中）In today’s digital era， we are constantly surrounded by news， both positive and negative．While staying informed is crucial， the continuous flood of headlines， especially something upsetting， can sometimes overload us． 13.　　 Thus finding a balance between staying informed and maintaining mental well－being is essential for a healthy relationship with news． 　　News tiredness arises when individuals feel emotionally worn out from consuming excessive information， particularly negative reports． 14.　　 These may include increased anxiety， emotional numbness （麻木） over time， and difficulty concentrating on daily tasks． Psychologists warn that long－term exposure to upsetting news may even weaken one’s ability to care about others． 　　To promote healthy news consumption， consider the following strategies： set specific times to catch up on news． For example， avoid checking news immediately after waking up or before sleeping， as these moments are critical for mental relaxation． Choose reliable news outlets that offer balanced reporting rather than sensational headlines designed to cause panic． 15.　　 And skip stories that merely add unnecessary stress． 　　When a story upsets you， look for ways to contribute， such as volunteering， donating， or spreading awareness． 16.　　 Additionally， you can extend your contribution， such as inviting others to join you or tracking small impacts， to handle the bad feelings． 　　17.　　 Follow social media accounts or newsletters — dedicated to sharing acts of kindness， scientific breakthroughs， or community achievements． Remind yourself that while challenges exist， countless good deeds and progress occur daily． 　　Remember， you don’t need to consume every piece of news to be an informed citizen． By cultivating mindful media habits and intentionally balancing information intake， you can stay informed without sacrificing emotional well－being． A．Such state leads to measurable consequences． B．Check news constantly to avoid missing updates． C．These active responses help reduce feelings of helplessness． D．Turning to positive news sources helps balance negative news． E．Sharing inspiring news online contributes to attracting more attention． F．Focus on news that directly affects you or matches your interests．
