영어 모의고사 (자동 편성)

Every plastic product carries a small recycling mark, but few students know ①what these marks mean. Each symbol contains a number ②that shows what material the item is made of. Reading these marks is similar to ③reading nutrition labels on snacks, which tell you exactly what is inside. Likewise, ④throwing plastic away without checking its mark can send a reusable item straight to a landfill. Some marks even show that a material cannot be recycled at all, so it must ⑤sorted separately.

Central High School will host its annual career fair next Thursday in the main gymnasium. More than thirty companies ①are expected to set up booths to introduce different careers. Students can talk directly with workers ②who represent fields such as medicine, engineering, and design. Each booth will offer a short activity ③designed to let visitors experience a small part of the job. In addition, three guest speakers will give short talks ④about their career paths during the lunch break. Teachers strongly encourage all students ⑤attend, even those who already have a career in mind.

Minjun used to leave half of his lunch tray full of ①untouching rice and vegetables every day. Last spring, his class started a campaign ②called "Clean Plate Day" to reduce food waste. However, his teacher explained that leftover food thrown away every day ③adds up to a huge amount of waste. She compared uneaten food to money ④dropped carelessly on the street, which nobody bothers to pick up. He decided to take only what he could finish and ⑤to try new vegetables slowly.

Earthquakes strike without any warning, which is exactly why the seconds immediately after the shaking begins matter more than any other moment in an ①emergency. Many people instinctively want to run outside during a quake, imagining that open space is always ②more dangerous than a building, but this instinct can be dangerous, since falling glass, signs, and debris often cause more injuries near exits and windows than sturdy interior spaces do. Furniture that seems merely inconvenient during a fire drill, such as a heavy desk, becomes a ③lifesaving shield when the ceiling above begins to crack. After the shaking stops, experts warn that the greatest remaining danger is often a damaged structure rather than a second earthquake, so ④calmly checking for hazards before moving is just as important as reacting ⑤quickly at the first tremor.

Stairs seem too ①ordinary to 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 ②different story: falls on stairways send more people to the hospital each year than almost any other household accident. Familiarity ③discourages a kind of autopilot mode, in which a person stops looking at each step and instead relies on memory of where the stairs should be, a habit that fails the moment something ④unexpected occurs, such as a missing step or a loose railing. Safety officials recommend a few ⑤unglamorous habits: keep one hand free, use the handrail, and turn on the light before stepping onto a dark staircase.

Every summer, doctors warn about the danger of heatstroke, a serious condition in which ___________. This condition can be life-threatening if it is not treated quickly. To prevent heatstroke, drink plenty of water throughout the day, avoid outdoor activities during the hottest hours, and wear light, loose clothing.

Physical education class often feels like the one period of the day when students can finally move freely, which sometimes leads them to skip the warm-up routine that teachers insist on before any real activity begins. (A) Beyond warming up, wearing proper footwear matters more than most students realize; running in worn-out sneakers with little grip left on the sole significantly raises the chance of a twisted ankle. (B) Coaches often compare an unwarmed muscle to a cold rubber band that snaps rather than stretches under sudden pressure. (C) Cold muscles, however, are noticeably less flexible than warmed ones, and stretching a stiff hamstring or ankle too quickly can cause a strain that keeps a student off the field for weeks.

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. (A) When the plastic sheets finally came down, the mural looked remarkably unified, not despite the many different hands involved, but because each hand had been given a task suited to what it could do well. (B) The project leader solved this by dividing the huge design into small, connected sections and assigning each volunteer a section matched to their comfort level, from simple solid-color backgrounds to detailed flowers. (C) I worried that combining so many different skill levels would create an ugly, mismatched result, since some volunteers had painted for years while others, including me, had never held a large brush before.

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. (A) Wearing a helmet does not prevent a fall, but it dramatically reduces the chance of a serious head injury when one occurs. (B) 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. (C) Some argue that a short trip to a nearby store does not require any special protection, since the risk feels distant and unlikely, but most accidents actually happen close to home, on familiar streets where riders feel too comfortable to expect danger.

Good morning, residents of Green Apartment! We would like to introduce a simple way to protect our environment, since used batteries contain harmful chemicals that should never be thrown away with regular trash. (A) If these chemicals leak into the soil, they can pollute water and harm plants, so our building has installed a special collection box for used batteries near the main entrance. (B) We appreciate your effort to keep our neighborhood clean and safe, and thank you for your cooperation and kindness. (C) Please place your old batteries inside this box instead of the trash can, since the box, which is emptied every month, is easy for anyone to use.
