Setting a career plan early in high school offers several important ①benefits. First, having a general direction helps students choose subjects and activities that support their goals, instead of picking them ②randomly. Second, a plan gives students a sense of purpose, which can make schoolwork feel more meaningful. However, an effective career plan should remain ③rigid, since interests and circumstances often change during the teenage years. Career counselors therefore recommend reviewing a plan every few months and ④adjusting it based on new experiences. In this way, careful planning provides a clear yet adaptable path toward genuine personal growth and long-term ⑤satisfaction.

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 ①shifts 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 ②impaired concentration, weakened memory, and a higher risk of anxiety and depression. It can also disrupt the hormones that regulate appetite, contributing to ③unhealthy 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 ④worsened grades, better mood, and fewer tardy arrivals. Despite this evidence, changing entrenched school schedules remains a slow and ⑤contentious process.

Time-management researchers frequently mention a principle known as Parkinson's Law, which states that ___________. According to this idea, a task that could be finished in one hour will often stretch to fill an entire afternoon if that much time is scheduled for it. Students who set vague deadlines frequently experience this effect, spending extra hours refining a report that was already complete. Employees given a full week for a simple project may also delay meaningful progress until the final days, even though the actual work requires far less effort. This pattern happens partly because people unconsciously adjust their pace to match perceived urgency. Setting shorter, more specific deadlines can counter this tendency, forcing tasks to fit within a tighter and more realistic window. By recognizing how flexible time encourages unnecessary delay, individuals can complete assignments more efficiently without sacrificing quality.

A growing number of health apps now track steps, sleep, and heart rate throughout the day, quietly building a detailed picture of a user's physical condition. By comparing this stream of data against patterns drawn from millions of other users, the app's algorithm can flag early warning signs, such as an irregular heartbeat, long before the person experiencing it would have noticed anything unusual. Doctors caution, however, that these apps are designed to detect patterns, not to diagnose illness, and that _______________.

Ambitious young athletes and the parents who support them sometimes assume that more training automatically produces better results, a belief that occasionally leads to a condition known as overtraining syndrome. Unlike ordinary fatigue that resolves after a few days of rest, overtraining syndrome develops gradually over weeks or months of insufficient recovery relative to training load, eventually producing persistent exhaustion, declining performance despite continued hard work, and increased susceptibility to illness and injury. Warning signs are often subtle at first, including disrupted sleep, irritability, and a loss of enthusiasm for a sport the athlete once genuinely enjoyed, which adults often mistake for ordinary moodiness. Recovery from full-blown overtraining syndrome can take months rather than days, which is why _______________.

Every summer, lifeguards repeat the same warnings to swimmers, yet drowning remains one of the most common causes of accidental death among teenagers. (A) Rip currents present a particularly deceptive threat, since the water's surface can appear calm even while a powerful current pulls a swimmer steadily away from shore. (B) Experts advise that anyone caught in such a current should swim parallel to the beach rather than struggling directly against it, since fighting the current head-on quickly exhausts even a strong swimmer. (C) Part of the problem is that danger in water rarely looks dramatic, since a swimmer in trouble often makes little noise and shows no obvious signs of panic.

Two drivers, equally distracted by their phones, run a red light in exactly the same careless manner. (A) Although both drivers behaved identically and made exactly the same reckless choice, society judges them very differently: one faces criminal charges and lifelong guilt, while the other receives, at most, a minor traffic ticket. (B) Philosophers call this troubling asymmetry moral luck, since factors entirely outside a person's control end up determining how severely we judge their moral character. (C) By pure chance, a child happens to be crossing the street in front of one driver but not the other, and the first driver kills the child while the second drives through safely.

Modern sports wearables, from wrist-worn fitness trackers to smart insoles, continuously collect data that would once have required a laboratory to measure. (A) However, the flood of data has also created a new challenge, since distinguishing a meaningful pattern from ordinary daily fluctuation requires expertise that many amateur athletes simply do not have. (B) Coaches use this constant stream of information to detect early warning signs of overtraining, sometimes noticing a decline in performance before the athlete consciously feels tired. (C) Because of this, many teams now rely on wearable data as a routine part of daily monitoring, checking it as automatically as they once checked a stopwatch.

주어진 문장: This durability is especially evident in modern debates about whether people can truly perform two demanding tasks at once. Long before cognitive scientists possessed the tools to observe the brain directly, Donald Broadbent proposed an influential model suggesting that the human capacity to process incoming sensory information is constrained by a structural bottleneck through which only a single stream of input can pass at any given instant. ( ① ) According to this filter theory, multiple channels of stimulation, such as competing voices in a crowded room, are initially registered at a shallow, physical level, but only one channel is selected for further, meaning-based analysis while the rest are blocked from advancing beyond that early filter. ( ② ) Although later researchers challenged the rigidity of this early selection mechanism, pointing to instances in which unattended information, such as one's own name, nevertheless breaks through and captures awareness, ( ③ ) the core insight that attention imposes a genuine processing limit rather than a mere matter of willpower has remained remarkably durable. ( ④ ) This basic bottleneck principle continues to inform contemporary explanations of why multitasking so reliably degrades performance on demanding tasks. ( ⑤ )

For this reason, nutritionists generally advise spreading moderate portions of protein evenly across several meals throughout the day rather than saving it all for one large post-workout meal. After a strenuous workout, muscle fibers experience thousands of microscopic tears, and the body immediately begins a repair process that ultimately makes the muscle stronger than it was before. ( ① ) This repair depends heavily on amino acids, the building blocks that protein supplies, which is why sports scientists recommend consuming protein within a couple of hours after training. ( ② ) Waiting too long to eat can slow recovery, since a muscle's sensitivity to amino acids gradually declines once that window closes. ( ③ ) Many athletes assume that eating an enormous quantity of protein in a single sitting will speed up this process. ( ④ ) But the body can only use a limited amount at once; the rest is simply burned for energy or stored as fat. ( ⑤ )
