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.

Aerobic exercise, such as jogging, swimming, or cycling at a steady pace, ①strengthens the heart by forcing it to pump larger volumes of blood with each beat. Over weeks of consistent training, the heart gradually enlarges and becomes more efficient, meaning it can deliver the same amount of oxygen to working muscles while ②beating fewer times per minute. This adaptation explains why trained athletes often have a much lower resting heart rate than sedentary individuals of the same age. Beyond the heart itself, aerobic activity encourages the body ③building new capillaries within muscle tissue, improving the delivery of oxygen and nutrients at a cellular level. Researchers have also found that regular aerobic exercise ④reduces inflammation throughout the body and improves the way cells respond to insulin. Because these benefits accumulate gradually rather than appearing overnight, most exercise physiologists recommend ⑤maintaining a consistent routine for at least several months before expecting dramatic improvements in endurance.

Imagine two factories ①making the same product: one in a country with strict carbon rules, and one in a country with almost none. The factory facing stricter rules often spends more, which can make its goods pricier than those ②made elsewhere. To fix this imbalance, some governments have introduced the carbon border adjustment mechanism, a policy charging imported goods a fee based on how much carbon ③were released while producing them. Supporters argue that the system protects domestic industries and ④pushes foreign manufacturers toward cleaner methods. However, critics claim it unfairly burdens developing countries, which often lack money to modernize factories quickly. For example, a small exporter in a poorer nation might struggle to pay the added charge, though it contributes little to global emissions. Still, if wealthier nations pair the policy with technical support, it could become a genuinely fair tool for ⑤cutting emissions worldwide.

Years ago, a small shoe company struggled to compete with larger, well-funded rivals in the market. Its products were ①solid, but customers rarely ②remembered the brand after a single purchase. Sales slowly ③decreased as people felt they were supporting something meaningful rather than simply buying a product. Other companies noticed this shift and began crafting their own narratives, hoping to create similar ④emotional connections. Eventually, the founder realized that a compelling story, told honestly, could turn ordinary customers into ⑤loyal supporters.

Have you ever noticed your mood shifting after scrolling through a friend's ①gloomy post online? However, researchers have ②discovered that emotional contagion also occurs online, where only text or images are exchanged, without any physical presence at all. For instance, when someone posts a ③negative comment beneath a cheerful photo, the comments that follow often turn noticeably more negative in tone. In contrast, a single ④kind comment can shift an entire thread toward positivity within minutes. Consequently, many experts now argue that being ⑤careless of what we post matters more than we typically assume.

Smartphones, tablets, and computer screens all emit a significant amount of blue light, a short-wavelength light that our eyes are especially sensitive to. During the day, exposure to blue light from the sun helps keep us alert and mentally sharp, which is generally beneficial. At night, however, the same wavelength can interfere with the body's natural preparation for sleep. Specialized cells in the retina detect blue light and send signals to the brain's internal clock, which results in _______________. Studies have found that people who scroll through their phones in bed before sleeping take longer to fall asleep and experience lighter, more easily disrupted sleep than those who avoid screens. Some devices now offer a night mode that shifts the display toward warmer tones, reducing blue light output in the evening. While this feature may help slightly, sleep researchers generally recommend limiting screen use altogether in the hour before bedtime for the best results.

Long before a user finishes typing a sentence, the keyboard on most smartphones has already begun guessing what word comes next. (A) The system also adapts to each individual, gradually learning a person's favorite phrases, slang, and even the names of friends that no generic dictionary would recognize. (B) This constant personalization, however, creates a subtle side effect that few users notice, since autocomplete may be quietly narrowing everyday vocabulary. (C) This feature relies on a language model trained to notice which words commonly follow one another, so it can offer a shortlist of likely candidates, saving users countless keystrokes over the course of a day.

Sleep is not a single, uniform state but a cycle that alternates between two very different modes: REM (rapid eye movement) sleep and non-REM sleep. (A) REM sleep, by contrast, brings rapid eye movements and brain activity resembling wakefulness, and is believed to help consolidate memories and process emotions. (B) A healthy night cycles through both stages several times, and disrupting either one can leave a person feeling unrested despite a full night in bed. (C) During non-REM sleep, particularly its deepest stage, the brain waves slow dramatically and the body focuses on physical repair.

Climate change deniers often seem to ignore evidence that contradicts their views, and psychologists have a specific explanation for this behavior. (A) For example, someone whose job depends on fossil fuels may search for reasons to doubt the data, even while insisting that they respect science. (B) This concept, called motivated reasoning, describes how people process information in ways that protect their existing beliefs and lifestyles rather than pursue objective truth. (C) Rather than being a simple failure of intelligence, this pattern reflects a well-documented psychological tendency studied for decades.

주어진 문장: This is why many people find it especially difficult to maintain healthy eating habits after a long, stressful day at work. Psychologist Roy Baumeister proposed a concept called ego depletion theory, which suggests that willpower functions like a muscle that gradually tires after repeated use. ( ① ) According to this theory, every act of self-control, from resisting a snack to concentrating on difficult homework, draws from the same limited mental resource. ( ② ) As this resource becomes depleted throughout the day, later decisions require more effort and are more likely to fail. ( ③ ) For instance, someone who exercises discipline avoiding distractions all morning may struggle to resist checking a phone by evening. Likewise, dieters report that self-control weakens sharply at night, after hours of resisting food. ( ④ ) Some researchers argue that short breaks, adequate sleep, and blood sugar levels can help restore this depleted resource. ( ⑤ ) Although later studies have questioned how strong this effect is, the theory still offers a useful framework for understanding why willpower seems to fade throughout a long day.
