영어 모의고사 (자동 편성)

Consider a student who genuinely intends to study for tomorrow's exam yet, when the evening actually arrives, chooses to ①watch another episode of a favorite show instead, ②promising herself she will surely study harder next week. This pattern, in which the pull of an immediate pleasure overwhelms the value of a distant benefit, ③appear again and again across ordinary life, from postponed exercise to delayed savings. People do not necessarily fail to understand that the future reward matters more; rather, whatever happens right now simply feels disproportionately more urgent and vivid than anything scheduled for later. Behavioral economists note that this preference weakens considerably once both options are ④pushed into the future, which is why planning a diet starting next month feels effortless compared with skipping dessert tonight. Such inconsistency helps explain why gym memberships go ⑤unused and retirement accounts remain underfunded, despite people's stated intentions.

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 ①that are responsible 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 little evidence ②that properly supervised resistance training harms growth plates in healthy children. The actual risk arises not from lifting weights itself but from poor technique, excessive load, and inadequate supervision, factors ③that can injure any part of a young athlete's body regardless of the activity involved. Major pediatric and sports medicine organizations now generally agree that structured strength programs, when ④teaching with correct form and appropriate weight, can safely ⑤improve bone density, coordination, and injury resistance in young athletes.

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 shifts later, ①making it difficult for teenagers to fall asleep before eleven at night. Yet school start times rarely adjust to this shift, ②forcing students to wake before their bodies are ready. The consequences extend well beyond simple tiredness. Chronic sleep loss during adolescence has been linked to impaired concentration, weakened memory, and a higher risk of anxiety and depression. It can also disrupt the hormones ③that regulating appetite, contributing to unhealthy weight gain over time. Some school districts have experimented with ④delaying start times by even thirty minutes, and early results suggest that students who gain that extra rest show improved grades, better mood, and fewer tardy arrivals. Despite this evidence, changing entrenched school schedules ⑤remains a slow and contentious process.

Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle that ①governs when we feel alert and when we feel drowsy. This clock is regulated primarily by a tiny cluster of neurons in the brain that responds to light entering through the eyes. When morning sunlight strikes the retina, the cluster signals the body to ②suppress sleep hormones and raise body temperature, preparing us for activity. As evening approaches and light fades, the same mechanism triggers the release of melatonin, a hormone that ③promotes drowsiness. 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 ④out of sync with the external environment. Such misalignment does not simply cause tiredness; it has also been associated with digestive problems and ⑤heightened concentration, suggesting that timing matters as much as total sleep hours.

A biosensor works by pairing a biological component, such as an enzyme or antibody, with an electronic device that converts a biological reaction into a signal a computer can read. When the target molecule binds to the biological component, it triggers a small measurable change that the device translates into a readable number. This design has already transformed diabetes management, letting patients monitor blood sugar continuously through a small sensor worn under the skin rather than pricking a finger several times a day. Engineers are now racing to extend the same principle to detect subtler targets, from cancer cells circulating in the bloodstream to trace contaminants in drinking water. _______________.

In our elective fashion design class, the first assignment was not to sketch a beautiful outfit but to design clothing for a specific, unusual situation, such as a rainy commute or a wheelchair user's daily routine. I initially found the assignment strange, since I had imagined fashion design as primarily about appearance rather than practical problem-solving. Researching my chosen situation, a delivery worker who bikes through the city in all weather, changed how I approached the project entirely: _______________. My final design looked far simpler than the elaborate sketches some classmates produced, yet our teacher praised it precisely because every choice solved a real problem the wearer would actually face. I finished the unit understanding that thoughtful design often begins with a person's needs, not with a striking image.

When people look back on a multi-day journey, they rarely recall every hour with equal clarity; instead, memory tends to compress the entire experience into just a few representative moments. Psychologists have found that two points carry disproportionate weight in this process: the single moment when emotion reached its highest intensity, and whatever happened right before the experience concluded. Consider two hikers who complete an identical five-day trek. The first finishes with a grueling, rain-soaked final climb, while the second enjoys a calm, scenic descent on the last afternoon despite having endured an equally difficult ascent earlier in the trip. Even though both hikers faced comparable hardship overall, the second is far more likely to remember the journey fondly, simply because the trip ended pleasantly. This pattern reveals that _______________.

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 most closely associated with physical restoration. REM sleep, by contrast, brings rapid eye movements, near-total muscle paralysis, and brain activity that closely resembles wakefulness. Most vivid dreaming occurs during this stage, and researchers believe _______________. 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.

Many students think that reading a book quietly by themselves is enough, but book discussion classes add something that solo reading cannot provide. (A) When students explain their ideas out loud, they often discover thoughts they did not even know they had. Teachers who use discussion classes report that students remember plot details and themes far longer than students who only read silently and take a quiz afterward. (B) This happens because talking about a book forces the brain to organize scattered impressions into a clear argument. Discussion also teaches students to listen carefully, since they must respond directly to classmates instead of simply waiting for their own turn to speak. (C) Some students feel nervous about sharing their opinions at first, but most grow more confident after a few sessions. For these reasons, many schools are now adding weekly discussion sessions to their reading programs, even for short stories that used to be assigned only as silent homework.

Structural functionalism approaches society as a complex system of interdependent parts, each contributing to the overall stability and smooth operation of the whole, much as organs contribute to the survival of a biological body. (A) Robert Merton refined this framework by distinguishing manifest functions, the intended and openly recognized consequences of a social practice, from latent functions, unintended consequences that nonetheless help sustain the system. (C) Sociologist Talcott Parsons argued that institutions such as the family, education, religion, and government each perform necessary functions, so that removing or weakening any one institution threatens the equilibrium of the entire system. (B) Critics have long charged that functionalism, by emphasizing stability and equilibrium, struggles to explain social conflict and rapid change.
