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.

After an especially demanding training session, the instinct to collapse onto a couch and remain motionless is understandable, yet exercise physiologists increasingly ①recommend the opposite approach. Active recovery involves ②to perform 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. This gentle activity keeps blood circulating through tired muscles, which ③appears to help clear metabolic byproducts that accumulate during hard exercise more efficiently than complete stillness does. Some athletes worry that any movement at all will interfere with the repair process, but research suggests that truly light activity ④does not meaningfully slow healing and may even reduce the perceived soreness that follows a hard session. The key distinction lies entirely in intensity: active recovery is not a second workout in disguise but a deliberately gentle session ⑤designed to support, rather than compete with, the body's underlying repair mechanisms.

Many teenagers check their social media accounts dozens of times a day, worried that they might miss something ①important happening among their friends. 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. For example, a student scrolling through photos of a party she was not invited to may suddenly feel a wave of ②loneliness and regret, even though the event has already ended. Constantly refreshing 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 ③deepen feelings of anxiety rather than ④worsen them. Therefore, students should learn to ⑤limit their social media use and focus more attention on the relationships and activities directly in front of them.

Sleep hygiene refers to a set of simple daily habits that help the body prepare for consistent, ①restorative rest. Experts commonly recommend going to bed and waking up at the same time every day, even on weekends, because an irregular schedule ②clarifies the body's internal clock and makes it 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 to associate that space with ③wakeful activity rather than rest. Physical environment matters as well: a cool, dark, and quiet room tends to produce ④deeper 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 ⑤consistent set of cues trains an athlete's body to perform at a certain time each day.

Only a decade ago, translation apps produced sentences so ①awkward that users often laughed at the results rather than trusting them. Today, many of these apps rely on neural networks 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 ②chaotic. Frequent travelers now point their phone cameras at street signs and receive an ③instant translation overlaid on the screen. Even so, the technology still struggles with humor, sarcasm, and cultural nuance, areas where a single wrong word can ④completely change the intended meaning. For this reason, professional translators argue that these apps are best treated as a helpful ⑤starting point rather than a final, polished result.

During sleep, the brain does not simply rest; it actively reorganizes the day's experiences into lasting memories through a process called consolidation. Newly formed memories are initially ①fragile and stored primarily in a brain region called the hippocampus, which has ②unlimited long-term capacity. 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 ③durable, long-term storage. This replay strengthens the connections between neurons that encoded the original experience, making the memory more ④resistant to interference from unrelated events the following day. 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 ⑤extract general patterns from the material, suggesting that consolidation involves more than passive storage.

Parents and coaches sometimes worry that heavy resistance training might damage the growth plates in a young athlete's bones, cartilage regions near the ends of long bones that are ①responsible for lengthening as a child develops. This concern kept strength training out of many youth programs for decades. However, extensive research over the past twenty years has found ②little evidence that properly supervised resistance training harms growth plates in healthy children. The actual risk arises not from lifting weights itself but from ③poor technique, excessive load, and inadequate supervision. Major pediatric and sports medicine organizations now generally agree that structured strength programs, when taught with correct form and appropriate weight, can safely ④improve bone density, coordination, and injury resistance in young athletes. The key variable, in other words, is not whether children lift weights but how carefully that training is ⑤ignored.

When the body fights off an infection, the immune system relies heavily on adequate sleep to function effectively. During deep sleep, the body produces and releases cytokines, proteins that help regulate immune responses and coordinate the fight against harmful invaders. People who consistently sleep fewer than six hours a night show measurably weaker antibody responses after vaccination compared with those who sleep seven or eight hours, suggesting that _______________. Chronic sleep deprivation also appears to promote low-grade inflammation throughout the body, a state that has been linked to a higher risk of heart disease. Rather than being a passive state, sleep functions as an active period during which the immune system repairs itself and prepares for future threats.

주어진 문장: Better rested individuals, in turn, tend to have more patience and energy for the people around them. A growing number of people are practicing what is now called digital detox, the deliberate decision to stop using smartphones for a set period. ( ① ) Rather than checking notifications every few minutes, participants unplug for a weekend, a week, or sometimes even longer. ( ② ) Numerous studies suggest that this temporary withdrawal produces real benefits for both the mind and the body. ( ③ ) First, attention spans fragmented by constant notifications gradually recover, allowing people to concentrate on single tasks for longer stretches. ( ④ ) Second, avoiding screens before bedtime improves sleep quality, since blue light emitted by devices is known to disrupt natural sleep cycles. ( ⑤ ) Third, people freed from their phones often rediscover the pleasure of face-to-face conversations that had been replaced by texting. Critics argue that complete disconnection is impractical in a hyperconnected society, yet even brief, regular breaks appear to restore balance. Therefore, scheduling periodic digital detox sessions deserves serious consideration.

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.
