영어 모의고사 (자동 편성)

When someone's heart suddenly stops beating, the brain begins ① to suffer damage within minutes unless blood keeps circulating, which is why the actions taken by an ordinary bystander before paramedics arrive can matter as much as the treatment given at the hospital. Studies show that a person who ② receives CPR immediately from someone nearby is far more likely to survive than one who waits for professional help to arrive. Despite this, many people hesitate to start chest compressions, ③ worried that they might break a rib or make the situation worse. Medical instructors respond to this fear: a cracked rib heals, but a brain ④ depriving of oxygen for too long does not. Modern CPR training has also been simplified, focusing on firm, rhythmic chest compressions rather than the more complicated combination of breaths and compressions once required, ⑤ making the skill easier for ordinary students to learn and remember under pressure.

Last summer, our neighborhood association invited students to help paint a mural on the long wall beside the community center, and nearly forty volunteers with completely different painting abilities showed up on the first day. I worried that combining so many different skill levels would create an ① ugly, mismatched result, since some volunteers had painted for years while others, including me, had never held a large brush before. The project leader solved this by dividing the huge design into small, connected sections and assigning each volunteer a section matched to their ② comfort level, from simple solid-color backgrounds to detailed flowers. Beginners filled in wide open skies, while experienced painters added fine details like veins on leaves or shadows under birds. When the plastic sheets finally came down, the mural looked remarkably ③ unified, not despite the many different hands involved, but because each hand had been given a task ④ unrelated to what it could do well, which made the ⑤ collaboration feel effortless in the end.

Safety signs surround us so constantly that most people stop ① consciously reading them soon after learning to drive. This is precisely the outcome that sign designers hope to avoid, since a sign that requires careful thought to interpret in an emergency has already ② succeeded at its purpose. Colors and shapes are chosen deliberately rather than randomly: red almost universally signals danger or prohibition, yellow signals ③ caution, and green marks safety, a system consistent enough that a traveler in an unfamiliar country can often guess a sign's meaning without reading a word. Symbols replace text wherever possible for the same reason, allowing a running figure or a flame icon to communicate ④ instantly to someone who may not speak the local language. Ignoring a familiar sign because it has become part of the background remains one of the most common and ⑤ preventable causes of accidents in public spaces.

Science labs feel far safer than they actually are, largely because the equipment looks harmless and the experiments are carefully planned by a teacher. This false sense of security leads some students to skip small precautions, such as wearing safety goggles for a "simple" experiment. Chemical reactions, however, do not distinguish between a professional laboratory and a classroom; _______________. Teachers repeatedly emphasize reading each instruction before touching any material, since even a familiar-looking chemical can behave unpredictably when combined with something new.

On the first day of our improv theater workshop, the instructor gave us a rule that seemed impossible to follow: never say no to whatever another performer suggests. If a scene partner claimed the empty classroom was actually a submarine, our job was to accept that fact instantly and build on it, rather than correcting or rejecting the idea. I found this terrifying at first, since improv offers no script to hide behind and no time to plan a clever line in advance. Over several weeks, though, I noticed that _______________. The instructor explained that improv is not really about being naturally quick-witted, but about trusting a partner's idea enough to build on it rather than protecting your own. That single lesson, oddly, changed how carefully I listened even in ordinary conversations.

When an image-generating program produced a strikingly detailed painting in the exact style of a well-known illustrator within seconds, my art club spent an entire meeting arguing about what it actually meant for artists. (A) Others worried that the program had been trained on thousands of real illustrations scraped from the internet without the original artists' permission, meaning the tool's impressive results were quietly built on other people's uncredited labor. (B) Some members felt excited, imagining the software as a helpful tool that could speed up brainstorming or generate quick backgrounds for their comics. (C) A few pointed out that the final image, however skillful it looked, reflected no personal memory, struggle, or intention, only patterns learned from existing pictures, and the debate never reached a clear conclusion.

Whenever someone learns that I spend hours drawing comics that almost nobody else ever sees, they usually ask why I bother, since the work will never be published or praised by a large audience. (A) Creating something, I now believe, often serves the creator first, giving shape to a feeling or idea that would otherwise stay vague and unexpressed. (B) For a long time, I struggled to answer that question honestly, assuming that art only counted as worthwhile once other people recognized it. (C) Watching my younger brother build enormous, pointless block towers purely for the joy of knocking them down, though, helped me understand something I had been missing.

A single careless movement, in other words, could ruin an entire page of otherwise careful work. When a classmate began writing her diary entries in elaborate, flowing calligraphy instead of ordinary handwriting, I assumed she was simply trying to make her notebook look decorative. ( ① ) Curious, I asked her to teach me one afternoon, and I quickly discovered that calligraphy demands far more patience than I had expected. ( ② ) Every stroke has to be planned before the pen touches the paper, since a brush pen cannot be casually corrected once ink has already spread across the page. ( ③ ) She told me that slowing her hand down to this deliberate pace actually helped her think more clearly, because rushing through a sentence in calligraphy simply was not physically possible. ( ④ ) What began as decoration for her gradually became a kind of meditation, a rare part of her day when she could not multitask or hurry. ( ⑤ ) I left that lesson with ink-stained fingers and a newfound respect for how much concentration a single beautifully written word can require.

Under such chaotic conditions, even a familiar hallway can suddenly feel like unknown territory. Every semester, students groan when the fire alarm rings for another routine drill, filing out of the building as if the exercise were simply a break from class. ( ① ) This casual attitude, however, overlooks why the drill exists in the first place. ( ② ) During an actual fire, thick smoke can fill hallways within minutes, cutting visibility to almost nothing and making it dangerously easy to panic or take a wrong turn. ( ③ ) Repeating the same evacuation route again and again trains the body to move automatically, even when the mind is too frightened to think clearly. ( ④ ) Firefighters note that students who have practiced an escape route calmly walk toward the nearest exit purely out of habit, while those unfamiliar with the building often freeze or hesitate at doorways. ( ⑤ ) A fire drill that feels pointless in the classroom can therefore become the very reason a real evacuation succeeds without injury.

Sometimes the leader also brings up a surprising detail that no one else noticed. Our school's book club, Page Turners, meets every Wednesday to discuss a book the members chose. ( ① ) At the start of each month, students suggest titles and vote to pick one. This way, everyone feels some ownership over what the club reads next. ( ② ) Before each meeting, members read several chapters and prepare a few questions. During the meeting, the leader opens discussion by asking a question about the story's main idea. ( ③ ) Then members take turns sharing their opinions, even when they disagree with each other. For example, students once argued for a long time about a character's difficult choice. ( ④ ) Such debates, though sometimes loud, help members understand different points of view. At the end of the semester, the club holds an event to recommend favorite books. ( ⑤ ) Through this process, reading becomes less like homework and more like a shared conversation.
