영어 모의고사 (자동 편성)

When someone's heart suddenly stops beating, the brain begins ①to 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 ②receives 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, ③worried that they might break a rib or make the situation worse. Medical instructors respond to this fear: a cracked rib heals, but a brain ④depriving 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, ⑤making the skill easier for ordinary students to learn and remember under pressure.

Stairs seem too ordinary ①to be dangerous, which is why many people treat them carelessly, texting, carrying an armful of books, or skipping two steps at a time. Emergency room records tell a different story: falls on stairways ②sends more people to the hospital each year than almost any other household accident. Familiarity encourages a kind of autopilot mode, in which a person stops ③looking at each step and instead relies on memory of where the stairs should be, a habit that ④fails the moment something unexpected occurs, such as a missing step or a loose railing. Safety officials recommend a few unglamorous habits: keep one hand free, use the handrail, and turn on the light before ⑤stepping onto a dark staircase.

My cousin, who has never taken a single music lesson, recently ①used a composing app on her phone to write a short song for her friend's birthday video. Watching her work, I realized the app ②handled much of the technical difficulty that used to stop beginners from composing at all, automatically keeping her melody in key and ③suggesting chords that matched the mood she selected. What the app could not do, however, was decide which four notes actually felt right for the opening line, or when a pause said more than another note would have. She spent nearly an hour ④adjusting a single short phrase until it matched the feeling she wanted to capture, deleting and replaying it dozens of times. Watching her patient trial and error, I understood that these tools lower the technical barrier to making music, but they do not remove the very human task of ⑤decide what a piece of music is actually trying to say.

Whenever someone learns that I spend hours drawing comics that almost nobody else ever sees, they usually ask why I ①bothering, since the work will never be published or praised by a large audience. For a long time, I struggled to answer that question honestly, ②assuming that art only counted as worthwhile once other people recognized it. Watching my younger brother build enormous, pointless block towers purely for the joy of knocking them down, though, ③helped me understand something I had been missing. He never once asked whether his tower was good; he simply needed to build the version of it that existed in his head before he could feel satisfied. Creating something, I now believe, often serves the creator first, ④giving shape to a feeling or idea that would otherwise stay vague and unexpressed. Whether or not anyone else ever sees the result, that private act of shaping an idea into something real still seems ⑤to matter enormously.

For many students, the walk to school feels so ①routine that safety becomes an afterthought, yet a surprising number of accidents occur within a few blocks of the school gate. Part of the danger comes from convenience: students often cut across a busy street rather than walking the extra minute to the nearest crosswalk, assuming they can judge the traffic gap ②correctly. Wearing dark clothing during these hours can make a student almost ③invisible until a car is dangerously close. Simple choices, such as using a marked crosswalk, waiting for the pedestrian signal, and adding something reflective to a backpack, cost only a few extra seconds each morning. Traffic safety officials argue that these small habits, repeated daily, do more to ④ignore injury than any single safety ⑤campaign ever could.

Whenever people discuss the future of reading, one debate never seems to end: e-books or paper books? Supporters of e-books point out that a single device can hold ①thousands of titles, which makes traveling with a full library incredibly ②light. Readers can also change the font size, look up a word instantly, and carry their entire collection in one bag. Fans of paper books, however, argue that something important is ③lost on a screen. Many readers say they remember a paper book's plot more clearly, perhaps because they ④recall where a scene appeared on the page. Screens also invite distraction, since a single notification can pull a reader ⑤closer to the story in seconds. Interestingly, several recent surveys suggest that most young readers do not choose one format forever. Instead, they switch between paper and digital depending on the situation, treating the debate less as a contest and more as a matter of convenience.

Accidents rarely wait for a doctor to be nearby, which is why basic first aid knowledge can make a critical difference in the first few minutes after an injury occurs. Many students assume that only professionals should touch an injured person, fearing that any mistake might make things worse. In reality, a few simple actions, such as applying steady pressure to a bleeding wound or keeping an unconscious person's airway clear, can prevent a minor injury from becoming a life-threatening one. _______________, since every minute without basic care allows a treatable injury to worsen. Of course, first aid is never a substitute for professional medical treatment, and it should never replace an emergency call.

Walking down a crowded street while staring at a phone screen has become such a common sight that it barely draws attention anymore. Researchers describe this as a kind of tunnel vision: a person absorbed in a text message processes only a narrow slice of the surrounding environment. Hospitals have reported a steady rise in injuries linked to distracted walking, ranging from minor scrapes after tripping over a curb to serious collisions with moving vehicles at intersections. What makes this danger especially difficult to address is that _______________.

This small difference in preparation determines whether an item can be reused or simply thrown away as waste. Sorting your trash correctly is one of the simplest habits that protect our environment. ① When you separate paper, plastic, glass, and cans, recycling centers can process each material more efficiently. ② For example, plastic bottles should be rinsed and have their caps removed before being thrown away. Paper soaked with food or oil, however, cannot be recycled and must go into general waste. ③ Sorting garbage is similar to organizing a closet, where each type of clothing has its own shelf. If items are mixed together carelessly, finding what you need later becomes difficult. ④ Likewise, mixing recyclables with ordinary trash makes the whole recycling process complicated. Many students believe that sorting trash takes too much time, but it actually requires only a few extra seconds. ⑤ Therefore, learning these basic rules now helps you build a habit that benefits your entire community.

주어진 문장: These habits include the way we use light, water, and electronic devices every day. Every day, we leave behind marks of the gases that warm our planet, much like footprints left in wet sand. ① These marks, often called our carbon footprint, come from small choices such as driving, eating, and using electricity. ② Many students think that only large factories create these marks, but ordinary habits at home also matter greatly. ③ For example, turning off lights when leaving a room reduces the energy that power plants must produce. ④ Walking or biking to school instead of riding in a car also lowers the amount of gas released into the air. In contrast, leaving devices plugged in all night quietly increases our footprint without our notice. ⑤ Therefore, students who practice these simple habits regularly can shrink their footprint significantly. Small daily choices, repeated over time, become powerful tools for protecting the environment we all share.
