Only a decade ago, translation apps produced sentences so awkward that users often laughed at the results rather than trusting them. Today, many of these apps rely on neural networks ① that analyze entire sentences at once, capturing context instead of translating word by word. This shift has made everyday tasks such as reading a foreign menu or chatting with an overseas friend remarkably smooth. Frequent travelers now point their phone cameras at street signs and ② receiving an instant translation overlaid on the screen. Even so, the technology still struggles with humor, sarcasm, and cultural nuance, areas ③ where a single wrong word can completely change the intended meaning. A joke that depends on wordplay in one language may become confusing once it ④ is translated literally into another. For this reason, professional translators argue that these apps are best treated as a helpful starting point rather than a final, polished result that no human ⑤ needs to review.

Across the world, teenagers are chronically short on sleep, often getting two or three hours less than the eight to ten hours experts recommend for their age. Part of the problem lies in biology: as puberty begins, the body's internal clock naturally ① shifts later, making it difficult for teenagers to fall asleep before eleven at night. Yet school start times rarely adjust to this shift, forcing students to wake before their bodies are ready. The consequences extend well beyond simple tiredness. Chronic sleep loss during adolescence has been linked to ② impaired concentration, weakened memory, and a higher risk of anxiety and depression. It can also disrupt the hormones that regulate appetite, contributing to ③ unhealthy weight gain over time. Some school districts have experimented with delaying start times by even thirty minutes, and early results suggest that students who gain that extra rest show ④ worsened grades, better mood, and fewer tardy arrivals. Despite this evidence, changing entrenched school schedules remains a slow and ⑤ contentious process.

Many students ①assume that perfectionists work harder than everyone else, but psychologists describe a puzzling pattern called the perfectionism-procrastination cycle. Because perfectionists set impossibly high standards, they often feel ②anxious before they even begin, and the task feels overwhelming. They then ③accelerate the work to avoid facing their own unrealistic expectations, even though delay only increases their stress later. Likewise, an employee facing an important report may check emails repeatedly rather than begin drafting, fearing an early attempt will seem ④inadequate. Ironically, this avoidance guarantees the very failure that perfectionists dread, since ⑤rushed, last-minute work rarely meets their own high standards.

Psychologist Leon Festinger introduced social comparison theory, which explains that people ①evaluate their own abilities and opinions by comparing themselves with others. According to this theory, individuals engage in upward comparison when they measure themselves against someone who appears more ②successful, attractive, or accomplished. For instance, a teenager browsing vacation pictures posted by classmates may begin to feel that her own ordinary life is somehow ③inadequate. Unlike comparing oneself with someone in a similar position, which can sometimes ④boost confidence, upward comparison frequently triggers envy, dissatisfaction, and lower self-esteem. Researchers have found that frequent upward comparison online is linked to ⑤lower depression and anxiety.

Sleep debt refers to the cumulative gap between the amount of sleep a person needs and the amount they actually get. Unlike a financial debt, however, this deficit cannot simply be repaid with a single long weekend of rest. When someone loses two hours of sleep every night for a week, the body does not treat the shortage as fourteen separate small losses; instead, it accumulates the deficit, and _______________. Researchers have found that even modest, chronic sleep restriction gradually impairs reaction time and decision-making, often without the affected person noticing the decline. This is because subjective feelings of tiredness tend to plateau after a few days, even as objective performance keeps deteriorating. Consequently, people frequently underestimate how much sleep debt they are carrying until a demanding task suddenly exposes the accumulated cost.

Retailers use a variety of techniques designed to encourage customers to make unplanned purchases. Placing small, inexpensive items near checkout counters, for example, tempts shoppers who are already waiting in line with little else to do. Online stores achieve a similar effect through countdown timers that create a false sense of urgency, suggesting that a deal will vanish within minutes. Bright colors, cheerful music, and pleasant scents are also carefully chosen to put customers in a relaxed mood, making them less likely to think critically about their spending. Critics argue that these tactics ___________. Supporters of the industry insist that such techniques merely make shopping more enjoyable and are not inherently deceptive.

During sleep, the brain does not simply rest; it actively reorganizes the day's experiences into lasting memories through a process called consolidation. (A) Sleep researchers have demonstrated this effect experimentally: participants who slept after learning a list of word pairs recalled more items the next day than participants who remained awake instead. Crucially, the benefit was not limited to simple recall; sleep also seemed to help participants extract general patterns from the material, suggesting that consolidation involves more than passive storage. (B) Newly formed memories are initially fragile and stored primarily in a brain region called the hippocampus, which has limited long-term capacity. (C) While a person sleeps, particularly during the deep stages of non-REM sleep, neural activity replays these fresh memory traces in rapid, compressed sequences, gradually transferring the information to the cortex for more durable, long-term storage. This replay strengthens the connections between neurons that encoded the original experience, making the memory more resistant to interference from unrelated events the following day.

In other words, the two stages appear to serve complementary purposes, one restoring the body and the other restoring the mind. 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. ( ① ) During non-REM sleep, especially its deepest stage, the brain waves slow down dramatically, the body temperature drops, and tissue repair and growth hormone release reach their peak. ( ② ) This is the period most closely associated with physical restoration. ( ③ ) REM sleep, by contrast, brings rapid eye movements, near-total muscle paralysis, and brain activity that closely resembles wakefulness. ( ④ ) Most vivid dreaming occurs during this stage, and researchers believe it plays a central role in consolidating memories and processing emotional experiences. ( ⑤ ) A healthy night typically cycles through both stages four or five times, with non-REM dominating the early hours and REM periods lengthening toward morning. Disrupting either stage, through frequent awakenings or alcohol use, can leave a person feeling unrested even after a full night in bed.

This grogginess occurs because the brain has not fully completed a sleep cycle and is abruptly pulled out of its deepest phase. A short nap taken in the early afternoon, often called a power nap, can noticeably sharpen attention and mood without leaving a person groggy afterward. ( ① ) The key lies in timing: naps limited to roughly twenty minutes allow the brain to pass through the lightest stages of sleep while avoiding the deeper stages associated with slow-wave activity. ( ② ) If a nap extends much beyond that window, the sleeper risks waking during deep sleep, which produces a foggy, disoriented feeling known as sleep inertia that can persist for thirty minutes or more. ( ③ ) Laboratory studies comparing napping and non-napping groups have repeatedly shown that a brief nap improves reaction time and short-term memory almost as effectively as a full night of extra rest. ( ④ ) Interestingly, the benefit appears strongest when the nap occurs several hours after waking, since this is when the body's natural dip in alertness makes rest most effective. ( ⑤ ) For this reason, many workplaces now designate quiet rooms where employees can recharge briefly during the day.

주어진 문장: Without such outside checks, companies could easily present exaggerated or even false claims as genuine achievements. As consumers become more aware of global social and environmental issues, many now expect companies to take responsibility beyond simply selling products. ( ① ) This expectation has given rise to ethical consumption, in which shoppers consider factors such as fair wages, humane treatment of animals, and environmental sustainability before making purchases. ( ② ) Companies that ignore these concerns risk public backlash, especially when unethical practices are exposed through investigative journalism or social media. ( ③ ) Some corporations have responded by publishing detailed sustainability reports, though critics question whether these documents reflect genuine change or merely serve as public relations tools. ( ④ ) Real accountability, according to many experts, requires independent verification rather than self-reported claims that cannot be easily checked. ( ⑤ ) Consumers, for their part, must also remain vigilant, since a company's marketing language does not always match its actual practices.
