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. 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. This is the period ①most closely associated with physical restoration. REM sleep, by contrast, brings rapid eye movements, near-total muscle paralysis, and brain activity that closely ②resemble wakefulness. Most vivid dreaming occurs during this stage, and researchers believe it ③plays a central role in consolidating memories and processing emotional experiences. A healthy night typically cycles through both stages four or five times, with non-REM ④dominating the early hours and REM periods lengthening toward morning. Disrupting either stage, through frequent awakenings or alcohol use, can leave a person ⑤feeling unrested even after a full night in bed.

Setting a goal such as 'I will study harder' rarely leads to ①meaningful improvement. According to psychologists Edwin Locke and Gary Latham, ②specific and challenging goals produce far better performance than vague or easy ones. This idea, known as goal-setting theory, suggests that ③clear targets direct attention and sustain effort over time. To apply this theory effectively, many educators recommend the SMART framework, which requires goals to be Specific, Measurable, Achievable, Relevant, and Time-bound. For instance, a student following this framework might say, 'I will memorize thirty new words every week for two months.' Because the goal includes a clear number and a deadline, progress becomes easy to ④track and evaluate. Challenging goals also tend to increase motivation, since people often work harder when a target feels meaningfully ⑤easy rather than trivially simple.

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 ①tailored to the individual rather than a generic weekly schedule. When the device detects signs of overtraining, such as an unusually high resting heart rate several mornings in a row, it may recommend a ②lighter workout or an extra rest day before fatigue turns into an actual injury. Amateur athletes often credit this kind of guidance with helping them train more ③consistently without pushing their bodies too hard. Sports scientists note an important caveat, however: a wrist-based sensor cannot fully capture the same physiological detail available in a professional lab, so its suggestions should be treated as an ④infallible medical judgment rather than a helpful guideline, particularly for anyone ⑤managing a chronic health condition.

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.

Across many countries, high schools begin classes early in the morning, often before eight o'clock. This schedule assumes that teenagers can simply go to bed earlier to compensate, but biology tells a different story. During adolescence, the body's internal clock shifts later, delaying the release of melatonin until well after ten at night. As a result, most teenagers are not physiologically ready to fall asleep until much later than younger children or adults. When early start times force them to wake before their bodies have completed a full sleep cycle, the mismatch accumulates into a chronic sleep debt that affects concentration and mood throughout the school day. Researchers who study this mismatch argue that _______________. Some school districts that delayed their start times by thirty minutes reported improvements in attendance, suggesting that the timing of the school day matters more than commonly assumed.

The Pomodoro Technique was originally developed using a simple kitchen timer shaped like a tomato. (A) Its creator discovered that dividing study time into short, timed intervals made it far easier to maintain concentration than studying for hours without pause. (B) Today, many productivity apps replicate this same twenty-five-minute cycle, allowing users to track their focused sessions digitally. (C) Based on this discovery, he designed a structured cycle of focused work followed by brief rest, which eventually became known worldwide.

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: Yet this strategy of delay backfires, since it leaves no time to revise or correct errors before the deadline. Many students assume that perfectionists work harder than everyone else, but psychologists describe a puzzling pattern called the perfectionism-procrastination cycle. ( ① ) This term describes how an intense fear of imperfect work causes people to delay starting a task rather than begin it. ( ② ) Because perfectionists set impossibly high standards, they often feel anxious before they even begin, and the task feels overwhelming. ( ③ ) They then postpone the work to avoid facing their own unrealistic expectations, even though delay only increases their stress later. ( ④ ) For example, a student writing a research paper might spend hours reorganizing notes instead of composing a single sentence that feels good enough. Likewise, an employee facing an important report may check emails repeatedly rather than begin drafting, fearing an early attempt will seem inadequate. ( ⑤ ) Ironically, this avoidance guarantees the very failure that perfectionists dread, since rushed, last-minute work rarely meets their own high standards.

주어진 문장: In other words, the default option is far more powerful than most people realize. Choice architecture refers to how decisions are designed. It determines which option is automatically selected unless a person chooses otherwise, known as the default option. ( ① ) Research consistently shows that people tend to stick with whatever is already set, even when changing it takes only seconds. ( ② ) Organ donation is a well-known example. Countries where citizens are automatically registered as donors unless they opt out show much higher donation rates than opt-in countries. ( ③ ) Retirement savings programs show a similar pattern, since employees automatically enrolled in a pension plan rarely cancel it. Voluntary sign-ups, in contrast, often delay indefinitely. ( ④ ) Critics argue that default options can be manipulated to benefit companies rather than individuals, so transparency about how defaults are chosen becomes essential. ( ⑤ ) Still, supporters insist that because some default must always exist, it should support people's own long-term interests rather than mere institutional convenience.

주어진 문장: This practice, sometimes described as superficial reporting, allows a company to appear responsible without actually reducing its environmental harm. ESG management refers to a company's efforts to consider Environmental, Social, and Governance factors alongside profit when making business decisions. ( ① ) Investors increasingly rely on ESG ratings to judge whether a company is managed responsibly and sustainably over the long term. ( ② ) Recently, however, many corporations have learned to boost their ESG scores without genuinely transforming their operations. ( ③ ) Some firms publish glossy reports filled with impressive statistics while their actual carbon emissions barely decline, exploiting the fact that ESG evaluation systems still lack consistent global standards. ( ④ ) This gap between appearance and substance has led critics to demand stricter, more transparent criteria for measuring corporate responsibility. ( ⑤ ) Genuine ESG management, in contrast, requires measurable targets, independent audits, and long-term accountability rather than one-time donations or attractive slogans. Investors who wish to identify truly responsible companies should therefore examine detailed disclosures instead of trusting labels alone.
