Minji had tried for years ①building a bedtime reading habit but always forgot once under the blanket. During summer, she found a method called habit stacking. It means ②attaching a new habit to an existing one so it acts as a reminder. Her existing habit was brushing her teeth every night, so she decided ③to place her book beside her toothbrush. After brushing her teeth, she would pick up the book, ④letting one action trigger the next. Encouraged by this success, Minji stacked another habit onto her morning routine, ⑤reviewing vocabulary words after making her bed.

An echo chamber refers to an online environment where people are mainly ①exposed to opinions that already match their own beliefs. This phenomenon occurs because social media algorithms tend to ②recommending content similar to what users have previously liked or shared, gradually narrowing the range of perspectives they encounter. As a result, individuals inside an echo chamber rarely engage with viewpoints ③that challenge their existing assumptions, which allows their original beliefs to grow increasingly extreme over time. For example, someone who frequently reads articles supporting one political party may begin to see the opposing party as entirely unreasonable, ④having never seriously considered its arguments. Political polarization, a significant issue in many countries today, is often ⑤linked to this pattern of selective exposure.

Sleep hygiene refers to a set of simple daily habits that ① helps the body prepare for consistent, restorative rest. Experts commonly recommend going to bed and waking up at the same time every day, even on weekends, because an irregular schedule confuses the body's internal clock and makes it ② harder to fall asleep on demand. They also advise reserving the bedroom for sleep alone, since using the bed to study, scroll through a phone, or watch videos teaches the brain ③ to associate that space with wakeful activity rather than rest. Physical environment matters as well: a cool, dark, and quiet room tends ④ to produce deeper sleep than one that is warm, bright, or noisy. None of these individual habits guarantees a good night's sleep on its own, but together they form a routine that gradually trains the body to expect and enter sleep more easily, much the way a consistent set of cues trains an athlete's body ⑤ to perform at a certain time each day.

Sociologist Mark Granovetter introduced an idea that seems ①contradictory at first glance, known as the strength of weak ties. According to this theory, people who see each other only ②occasionally, called weak ties, often provide more valuable information than close friends or family members, who are considered strong ties. This happens because strong ties tend to share the same social circles and, therefore, already possess ③similar knowledge. Weak ties, in contrast, move within different networks, which allows them to introduce ideas or opportunities that would otherwise remain unknown. For example, a former classmate rarely contacted might mention a job opening unavailable through one's immediate circle. Social media platforms have made maintaining such connections remarkably ④harder, letting users keep hundreds of loose acquaintances active without frequent face-to-face meetings. Consequently, these platforms function as efficient channels through which weak ties continue delivering ⑤fresh opportunities that close relationships simply cannot offer.

Aerobic exercise strengthens 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 beating fewer times per minute. This adaptation explains why _______________. Beyond the heart itself, aerobic activity also builds new capillaries within muscle tissue and improves how cells throughout the body respond to insulin.

Communication researchers have long studied why identical facts can produce very different public reactions depending on how they are presented. (A) Neither framing alone tells the complete story, so journalists who rely too heavily on either extreme risk distorting public understanding, and a balanced approach that honestly presents dangers while highlighting realistic solutions is far more likely to inspire lasting action. (B) When news outlets describe climate change primarily as a looming crisis, filled with images of disasters and warnings of irreversible damage, audiences often react with fear or, paradoxically, with hopeless resignation. (C) In contrast, when the same issue is framed as an opportunity, emphasizing innovative technologies and emerging green jobs, readers tend to feel more motivated to act and support policy change.

주어진 문장: Even a short break from checking their phones can trigger a nagging sense of unease. Many teenagers check their social media accounts dozens of times a day, worried that they might miss something important happening among their friends. ( ① ) This anxiety, known as FOMO, or the fear of missing out, arises when people believe that others are enjoying experiences from which they themselves are excluded. ( ② ) For example, a student scrolling 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. ( ③ ) Constantly refreshing feeds to avoid missing such updates, however, makes it difficult to concentrate on schoolwork or conversations happening in the present moment. ( ④ ) Moreover, this endless comparison with curated highlights of other people's lives tends to deepen feelings of anxiety rather than relieve them. ( ⑤ ) Therefore, students should learn to limit their social media use and focus more attention on the relationships and activities directly in front of them.

This built-in schedule does not simply respond to the clock on the wall; it is shaped directly by light itself. Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle that governs when we feel alert and when we feel drowsy. ( ① ) This clock is regulated primarily by a tiny cluster of neurons in the brain that responds to light entering through the eyes. ( ② ) When morning sunlight strikes the retina, the cluster signals the body to suppress sleep hormones and raise body temperature, preparing us for activity. ( ③ ) As evening approaches and light fades, the same mechanism triggers the release of melatonin, a hormone that promotes drowsiness. ( ④ ) Because this rhythm evolved around the natural cycle of day and night, modern habits such as staying indoors under artificial light or working night shifts can push the internal clock out of sync with the external environment. ( ⑤ ) Such misalignment does not simply cause tiredness; it has also been associated with digestive problems and reduced concentration, suggesting that timing matters as much as total sleep hours.

주어진 문장: This feeling is not simply nervousness about being alone, but a specific condition that researchers have begun to study closely. Many people feel a sudden wave of anxiety when their smartphone battery is nearly dead or they have left it at home. ( ① ) This intense discomfort, known as nomophobia, is short for "no-mobile-phone phobia," a term describing the fear of losing connection to one's phone. ( ② ) Nomophobia involves physical symptoms, including a racing heart, sweating, and restlessness, whenever a person cannot check messages or social media. ( ③ ) Researchers explain that this fear develops because smartphones have become tightly linked to social belonging; missing a notification can feel like being cut off from friends. ( ④ ) For example, some students check their phones dozens of times an hour, even during class, just to confirm nothing important has been missed. Therefore, experts suggest gradually reducing phone checks to weaken this anxious dependence. ( ⑤ ) Recognizing nomophobia as a real psychological pattern is the first step toward a healthier relationship with technology.

주어진 문장: This constant awareness of human presence is what distinguishes cobots from older industrial machines. Modern factories increasingly rely on collaborative robots, often called cobots, which are designed to work safely alongside human employees. ( ① ) Unlike traditional industrial robots that operate behind safety cages, cobots use sensors to detect nearby workers and adjust their movements accordingly. ( ② ) This technology allows humans and machines to share the same workspace without the risk of dangerous accidents. ( ③ ) In practice, cobots typically handle repetitive or physically demanding tasks, while human workers focus on tasks that require judgment and fine motor skills. ( ④ ) This division of labor increases overall efficiency, since each side contributes what it does best. ( ⑤ ) Manufacturers who have introduced cobots report fewer workplace injuries and higher worker satisfaction.
