Opening most camera apps today reveals a row of filters that can smooth skin, brighten eyes, and reshape a jawline before a photo is even taken, all powered by AI models ① trained to recognize facial features in real time. What began as a playful novelty has become a default setting for many users, subtly ② adjusting nearly every selfie posted online. Psychologists have grown concerned about a specific consequence of this shift: people increasingly compare their unfiltered reflection in a mirror to a filtered version of themselves ③ seeing constantly on a screen, a comparison that earlier generations never had to face. Some social media platforms have responded by ④ labeling heavily edited photos or banning certain filters that alter body shape. Whether such small warnings can meaningfully counter the daily flood of filtered images, however, ⑤ remains an open question that researchers are only beginning to study.

When Mina was a freshman, she often spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study in which children could eat one marshmallow ①immediately or wait for two. Researchers found that children who waited ②longer showed better academic performance and self-control years later. This ability to ③resist an immediate reward in favor of a larger future one is known as delayed gratification. Inspired by the study, Mina began saving half of her allowance each week instead of spending it all on snacks. At first, resisting small purchases felt surprisingly ④easy, especially when her friends were eating out. After three months, however, she had ⑤saved enough to buy a bicycle she had wanted for over a year.

Time blocking is a time-management technique in which a person divides the day into fixed blocks. Each block is then assigned to a single task. Instead of relying on a loose to-do list, the person decides exactly when each task will start and end. This approach ①lowers the mental effort of deciding what to do next, since the schedule already provides the answer. It also ②limits 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. Because each block has a ③vague boundary, unfinished work is ④less likely to quietly spread into the next task. Many people who adopt time blocking feel ⑤more organized throughout the day.

For most of last year, Junho refreshed his social media feed constantly, terrified of missing a party, a trending meme, or gossip among his friends. This restless anxiety, often called FOMO, or the fear of missing out, left him exhausted and strangely unsatisfied even after hours of scrolling. One weekend, his phone battery died during a hiking trip, and, to his surprise, he actually enjoyed the quiet afternoon without notifications interrupting his thoughts. Curious about this unexpected calm, Junho began deleting social apps for a few hours each day, gradually extending the breaks as weeks passed. Instead of dreading what he might be missing, he started noticing small pleasures, such as finishing a book or having an uninterrupted conversation with his family. This shift in attitude reflects ___________.

Many people believe that a new habit becomes automatic after only twenty-one days, but researchers who examined real behavior found a different number. This project, called the 66-day habit formation study, tracked volunteers who tried to adopt a new daily habit, like drinking water with lunch. Researchers measured how automatic each action felt over time and found that habits needed ___________. Yet the actual time varied widely, ranging from about eighteen days for simple habits to over two hundred days for difficult ones. This wide range explains why the popular twenty-one-day claim, though easy to remember, rarely matches real experience.

Soojin's rise as a content creator did not happen overnight, despite how it may have appeared to outsiders. (A) One video demonstrating a simple recipe, however, unexpectedly reached millions of viewers and changed everything almost instantly. (B) For months, she posted consistently despite earning very little attention, often doubting whether she should continue at all. (C) After that unexpected success, brands began reaching out, eventually allowing her to earn more than most entry-level jobs would pay.

After an especially demanding training session, the instinct to collapse onto a couch and remain motionless is understandable, yet exercise physiologists increasingly recommend the opposite approach. (A) This gentle activity keeps blood circulating through tired muscles, which appears to help clear metabolic byproducts more efficiently than complete stillness does. (B) Some athletes worry that any movement at all will interfere with the repair process, but research suggests that truly light activity does not meaningfully slow healing. (C) Active recovery involves performing low-intensity movement, such as a light jog, an easy swim, or a gentle bike ride, on days following intense exertion rather than resting completely.

A smartwatch strapped to a runner's wrist can now do far more than simply count steps; it monitors heart rate variability, running form, and recovery time, then uses that data to suggest a training plan tailored to the individual rather than a generic weekly schedule. (A) Sports scientists note an important caveat, however: a wrist-based sensor cannot fully capture the same physiological detail available in a professional lab. (B) When the device detects signs of overtraining, such as an unusually high resting heart rate several mornings in a row, it may recommend a lighter workout or an extra rest day before fatigue turns into an actual injury. (C) Amateur athletes often credit this kind of guidance with helping them train more consistently without pushing their bodies too hard.

Some schools have begun asking students to submit an early draft alongside the final version, specifically to preserve evidence of a student's own original voice. Highlighting an awkward sentence and instantly seeing three smoother alternatives has become a routine part of writing for many students, thanks to AI writing assistants built into word processors and browsers. ( ① ) These tools check grammar and spelling, of course, but the more advanced versions go further, suggesting clearer phrasing, flagging repetitive words, and even adjusting tone to sound more formal or more casual depending on the purpose. ( ② ) Teachers generally welcome the grammar and spelling support, since it frees up class time to focus on argument and structure rather than comma placement. ( ③ ) Concerns grow, however, around the tone and phrasing suggestions, which can gradually nudge every student's writing toward a similar, polished style. ( ④ ) This makes it harder to tell an individual voice from a suggestion generated by the same underlying model. ( ⑤ )

주어진 문장: This limitation means the technology has not yet fully replaced conventional factories. Three-dimensional printing technology is changing how products are designed and manufactured across many industries. ( ① ) Unlike traditional manufacturing, which often requires expensive molds and long production times, 3D printers can create complex objects directly from digital files within hours. ( ② ) This flexibility allows companies to produce small batches of customized products without the massive costs typically associated with mass production. ( ③ ) Hospitals now use 3D printing to create prosthetic limbs tailored precisely to individual patients, while automakers use it to build lightweight parts. ( ④ ) However, experts caution that 3D printing still struggles to match the speed of mass production for extremely large orders. ( ⑤ ) As printing materials improve and machines become faster, the technology is expected to play an increasingly central role in future manufacturing.
