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

When I joined the school broadcasting club two years ago, I only ①wanted to spend time with friends who shared my interests. Gradually, however, the club ②became something much more meaningful. I learned how to write short scripts, operate basic cameras, and ③editing simple video clips for school events. Our club also produced a short documentary about a local market, ④which taught me how much planning goes into even a five-minute video. What began as a casual after-school activity ⑤ended up shaping a clear direction for my future career.

Many students take a career aptitude test at some point in high school. This test is ①designed to measure a person's interests, strengths, and personality traits. It does not simply tell students which job to choose; instead, it helps them ②understand themselves better. For example, a student who enjoys solving problems might discover a ③hidden interest in engineering. However, the results should be used only as a guide, not as a ④temporary answer. Therefore, students should treat the test as a useful starting point, rather than a fixed decision that ⑤limits their future choices.

Science labs feel far ① 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 or tasting a substance out of ② curiosity. Chemical reactions, however, do not distinguish between a professional laboratory and a classroom; a small amount of the wrong substance splashed into an eye can cause ③ permanent damage within seconds, regardless of how basic the experiment seemed. Teachers repeatedly emphasize reading each instruction before touching any material, since even a familiar-looking chemical can behave ④ unpredictably when combined with something new. Most laboratory accidents, researchers note, do not happen during advanced or unusual experiments but during routine ones that students have performed many times before, precisely because familiarity breeds ⑤ caution rather than carelessness.

Every spring, the art club at Sejong High School creates one large mural together instead of individual paintings. The process begins with a session where members suggest themes and vote on their favorite idea. Once a theme is chosen, the club divides into small teams, each responsible for one section of the wall. One team sketches the outline while another mixes colors to match the design. Communication becomes essential at this stage, since each section must connect smoothly with the ones beside it. If one team paints too dark a shade, the whole picture can look unbalanced. Therefore, members regularly step back to compare their section with the rest of the mural. After several weekends, the teams combine their sections into a single image. The finished mural is displayed near the entrance, reminding everyone _______________________.

Last spring, I joined a one-day job experience program at a local hospital. A kind nurse named Ms. Park showed me around the ward and explained how nurses check patients' conditions. At first, I was nervous about talking to real patients. However, after helping an elderly patient find her room, I felt proud and relaxed. The busiest moment came when several patients needed attention at once, and the nurses worked together calmly. I realized that ___________. By the end of the day, my interest in nursing had grown even stronger.

Riding a bicycle is one of the most popular ways for teenagers to get around, yet many students still skip the one piece of equipment that could save their life: the helmet. Some argue that a short trip to a nearby store does not require any special protection, since the risk of a serious accident feels distant and unlikely. However, _______________. A sudden pothole, a car door opening without warning, or a patch of gravel can throw even an experienced cyclist off balance in an instant. Wearing a helmet does not prevent a fall, but it dramatically reduces the chance of a serious head injury when one occurs.

Sorting your trash correctly is one of the simplest habits that protect our environment. (A) 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. (B) 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. Therefore, learning these basic rules now helps you build a habit that benefits your entire community. (C) When you separate paper, plastic, glass, and cans, recycling centers can process each material more efficiently. 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.

Yet not everyone is convinced that turning reading into a game is entirely positive. A growing number of teenagers are joining book clubs that exist only on their phones. ( ① ) These apps let users track how many pages they read each day, write short reviews, and join group chats about a chosen book. ( ② ) Some students say the apps make reading feel less lonely, because they can share their honest reactions the moment they finish a chapter instead of waiting for a weekly meeting. ( ③ ) The apps also use gentle reminders and reading streaks to keep members motivated, turning a private habit into a small social game. ( ④ ) However, a few teachers worry that constant notifications from a reading app can pull attention away from the book itself, since users may spend more time chatting about the story than actually reading it. ( ⑤ ) Despite this concern, many students report that the sense of community keeps them reading books they would have quit halfway through if they had been reading completely alone.

This is because waiting for paramedics to arrive can cost a student the few minutes that make the difference between recovery and tragedy. A food allergy can turn an ordinary snack shared between classmates into a medical emergency within minutes, which is why schools now take ingredient labels more seriously than they once did. ( ① ) For someone with a severe allergy, even a trace amount of the wrong ingredient, transferred by a shared spoon or an unwashed hand, can trigger a reaction that closes the airway and becomes life-threatening if untreated. ( ② ) Friends of allergic students sometimes assume that a small bite would not cause serious harm, not realizing that the amount needed to trigger anaphylaxis can be smaller than a crumb. ( ③ ) Recognizing the early signs, such as swelling around the lips, hives, or sudden difficulty breathing, allows classmates and teachers to act before the reaction becomes severe. ( ④ ) Many schools now train staff to use an epinephrine auto-injector, a device that can reverse a dangerous reaction within seconds. ( ⑤ )
