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.

For decades, productivity advice has focused almost entirely on managing time efficiently, yet many experts now argue this approach ①emphasizes something important. Unlike time, which flows at a ②constant rate, human energy naturally rises and falls in cycles shaped by sleep, food, and mental fatigue. A person who tackles difficult tasks during a low-energy period, for instance, may need two hours to finish what takes thirty minutes at ③peak energy. Similarly, someone who forces themselves to keep working without rest often produces careless mistakes that require additional time to ④correct later. Advocates of energy management recommend identifying one's peak hours and reserving them for demanding work, while saving low-energy periods for ⑤routine tasks.

Willpower is like a muscle that becomes ①tired after being used too much, so people often run out of self-control by the end of a busy day. Many resolutions are unrealistic from the beginning, since people set goals that are far too ②easy to reach in a short time, and when a goal feels impossible, people quickly ③lose motivation and stop trying. Most resolutions do not offer any ④immediate reward, so people find it hard to stay motivated without seeing fast results. Understanding these reasons can help people design goals that are more ⑤realistic and rewarding.

Three years ago, he was a ①shy sophomore who dreamed of becoming a science teacher but doubted his own grades. He wrote down this single goal in his notebook and read it every morning before class. Instead of studying everything at once, he ②focused on one weak subject each month and asked his teachers for extra help. There were many moments when he wanted to ③give up, especially before difficult exams. However, he kept reminding himself why he had started. Today, Minho is studying to become a science teacher at university, proving that steady effort truly ④pays off, and his story continues to ⑤discourage his junior students.

Time blocking is a time-management technique in which a person divides the day into fixed blocks. ___________. Instead of relying on a loose to-do list, the person decides exactly when each task will start and end. This approach lowers the mental effort of deciding what to do next, since the schedule already provides the answer. It also limits multitasking, because each block is reserved for only one activity at a time. For instance, a student may block ninety minutes for math practice, leaving no room for messages or web browsing. Another student may reserve an evening block solely for vocabulary review, treating that time like a fixed appointment. Because each block has a clear boundary, unfinished work is less likely to quietly spread into the next task. Many people who adopt time blocking feel more organized throughout the day.

Habit researchers often note that people overestimate the role of motivation in daily routines. (A) As a result, they frequently give up soon after starting, blaming themselves for lacking discipline. (B) In contrast, Fogg's framework suggests that shrinking the task itself is more effective than boosting motivation. (C) Because motivation naturally rises and falls, relying on it alone often leads to inconsistent effort.

Social media algorithms are designed to keep users engaged by showing them content they are likely to enjoy. (A) As a result, users are gradually exposed to a narrower and narrower range of perspectives over time. (B) This pattern, known as an echo chamber, can eventually lead to greater political polarization within a society. (C) To achieve this goal, the algorithms recommend posts and articles similar to what a user has already liked or shared.

A planner is only useful if you actually use it well throughout the year, not just on January first. (A) For example, checking off completed tasks each morning helps you build momentum and stay motivated throughout the week. (B) Reviewing your notes every Sunday allows you to notice patterns and adjust your goals for the following week. (C) The most important step is to write one clear, specific goal at the top of each month.

Because this feedback loop relies entirely on light rather than on the clock on the wall, melatonin release can shift dramatically when a person travels across time zones or works through the night. Melatonin is a hormone produced by a small gland deep within the brain, and its release follows a remarkably predictable daily pattern. ( ① ) Levels stay low throughout the bright hours of the day, begin rising in the evening as darkness falls, peak in the middle of the night, and then decline again as morning approaches. ( ② ) This rhythm is controlled primarily by light: specialized cells in the eye detect brightness and send signals that either permit or suppress melatonin production, which is why exposure to bright screens late at night can delay its release and make falling asleep more difficult. ( ③ ) Unlike some hormones that directly cause the body to perform a task, melatonin does not force sleep to occur; instead, it signals to the rest of the body that night has arrived, preparing various systems to shift into a lower-energy state. ( ④ ) Because of this signaling role, taking melatonin supplements at the wrong time can shift a person's internal clock in the opposite direction from what was intended. ( ⑤ )

주어진 문장: At first glance, this seems to suggest that Dunbar's theory no longer applies in the digital age. Anthropologist Robin Dunbar proposed a concept now known as Dunbar's number, suggesting that human beings can only maintain about one hundred fifty stable social relationships at any given time. ( ① ) This limit, he argued, comes from the size of the human brain, which restricts how many meaningful connections a person can cognitively manage. ( ② ) In contrast, many social media users today have hundreds or even thousands of online friends and followers, a number far exceeding what Dunbar's research predicts. ( ③ ) However, having numerous digital contacts does not necessarily mean that all of these relationships are close or emotionally supportive. ( ④ ) Most users, when asked, admit that they interact regularly with only a small fraction of their total followers, while the rest remain largely unnoticed. ( ⑤ ) Therefore, Dunbar's number reminds us that genuine, lasting relationships require consistent effort and attention, something that a large online network alone cannot provide.
