Many teenagers check their social media accounts dozens of times a day, worried that they might miss something important happening among their friends. This anxiety, known as FOMO, or the fear of missing out, ①arises when people believe that others are enjoying experiences from which they themselves are excluded. For example, a student ②scrolling through photos of a party she was not invited to may suddenly feel a wave of loneliness and regret, even though the event has already ended. Constantly ③refreshed feeds to avoid missing such updates, however, makes it difficult to concentrate on schoolwork or conversations happening in the present moment. Moreover, this endless comparison with curated highlights of other people's lives tends to ④deepen feelings of anxiety rather than relieve them. Therefore, students should learn ⑤to limit their social media use and focus more attention on the relationships and activities directly in front of them.

A growing number of people are practicing what is now called digital detox, the deliberate decision ①to stop using smartphones for a set period. Rather than checking notifications every few minutes, participants unplug for a weekend, a week, or sometimes even longer. Numerous studies suggest that this temporary withdrawal ②produce real benefits for both the mind and the body. First, attention spans ③fragmented by constant notifications gradually recover, allowing people to concentrate on single tasks for longer stretches. Second, avoiding screens before bedtime improves sleep quality, since blue light ④emitted by devices is known to disrupt natural sleep cycles. Third, people freed from their phones often rediscover the pleasure of face-to-face conversations ⑤that had been replaced by texting.

The twenty-hour rule proposes that years of practice ①are not needed to become skilled at a new activity. Only about twenty hours of effort are needed to reach a useful level. Unlike theories ②claiming true mastery requires ten thousand hours, this rule targets a more modest goal. According to supporters, practicing any new skill produces the fastest visible improvement, since a beginner ③has room to grow. Someone learning guitar can typically strum simple chords and follow a basic song within twenty hours of ④daily practice. Advocates emphasize that the twenty hours must be deliberate and focused, broken into short daily sessions rather than one long stretch, and ⑤aims at fixing weaknesses rather than repeating what one already knows.

Behavioral economists use the term temporal discounting to describe how people ①undervaluing future rewards simply because those rewards are not immediate. This tendency explains why a student might choose to watch videos tonight rather than study for an exam that remains several weeks away, even though studying ②offers a far greater long-term benefit. A distant reward, no matter how valuable, feels psychologically smaller than a small reward ③available right now. This bias contributes to procrastination, since future consequences rarely feel urgent enough ④to motivate immediate action. To counter this tendency, students should convert distant goals into smaller, near-term milestones that feel more emotionally real. Setting weekly checkpoints rather than a final deadline can make future benefits feel closer and more concrete. Teachers and parents should provide immediate, meaningful feedback, since prompt recognition helps bridge the gap between present effort and delayed reward, ultimately ⑤reducing the urge to postpone tasks.

Scientists have identified certain gene variants that appear ①less frequently among elite endurance athletes than among the general population, along with a separate set that seems to favor explosive, power-based sports such as sprinting. One frequently studied variant, for instance, influences the proportion of slow-twitch versus fast-twitch muscle fibers a person naturally develops, a ratio that ②shapes whether a body leans toward endurance or explosive power. However, researchers caution strongly against interpreting these findings as evidence that athletic greatness is simply ③inherited. Even athletes who carry every favorable variant identified so far still require years of ④disciplined training to translate that genetic potential into actual performance. Genetics may set a rough ceiling on an individual's ultimate potential, but where any particular athlete lands within that range depends overwhelmingly on training quality, nutrition, coaching, and sheer ⑤determination.

Across many countries, high schools begin classes ①early in the morning, often before eight o'clock. This schedule assumes that teenagers can simply go to bed earlier to compensate, but biology tells a different story. During adolescence, the body's internal clock shifts ②earlier, delaying the release of melatonin until well after ten at night. As a result, most teenagers are not physiologically ready to fall asleep until much later than younger children or adults. When early start times force them to wake before their bodies have completed a full sleep cycle, the mismatch ③accumulates into a chronic sleep debt that affects concentration and mood throughout the school day. Researchers who study this mismatch argue that the underlying problem is not laziness or poor discipline among students, but a scheduling system built around adult rhythms rather than ④adolescent ones. Some school districts that delayed their start times by thirty minutes reported ⑤measurable improvements in attendance.

Minji spent nearly every evening watching Jimin, an online creator who streamed cooking videos and chatted casually with her viewers. Over several months, Minji began to feel as though she truly knew Jimin, laughing at her jokes and worrying whenever she mentioned having a difficult week. Whenever Jimin responded to a comment, even a simple one, Minji felt a small thrill of connection, as if they were becoming closer friends. One day, Minji excitedly waited outside a fan event, hoping that Jimin would recognize her from the countless messages she had sent. However, Jimin greeted her the same way she greeted every other stranger in line, without any hint of personal recognition. Standing there, Minji slowly realized that ___________.

Not all relationships that people form are equally close or meaningful. (A) Robin Dunbar, an anthropologist, argued that the human brain can only support about one hundred fifty stable relationships at once. (B) Consequently, most of the hundreds of online followers a person accumulates never become genuinely close acquaintances. (C) This cognitive limit applies regardless of how many friends or followers a person collects on social media.

Time perception can also shift according to age, not only according to attention or emotion. (A) This may occur because each year represents a smaller fraction of a person's total life as they grow older. (B) Many older adults report that entire years seem to pass more quickly than they did during childhood. (C) Psychologists studying this phenomenon have proposed that our sense of time speed is partly relative rather than fixed.

주어진 문장: This lack of accountability makes silence feel like a reasonable, even harmless, choice. Social psychologists describe a phenomenon called the bystander effect, in which individuals become less likely to help a victim as the number of witnesses increases. ( ① ) Each observer assumes someone else will step in, and this diffusion of responsibility leaves no one willing to act. ( ② ) Cyberbullying magnifies this problem, since a single humiliating post can be witnessed by thousands of people scattered across the internet rather than a few standing nearby. ( ③ ) Anonymity intensifies the effect further, allowing silent observers to scroll past cruel comments without feeling accountable for their inaction. ( ④ ) Some bystanders even worry that intervening publicly might make them the bully's next target, so they choose to remain silent instead. ( ⑤ ) However, silence signals approval to both the bully and the audience watching the exchange unfold. Experts insist that even a single supportive comment can disrupt this harmful pattern. Therefore, witnesses online must resist staying passive and instead speak up.
