Science labs feel far ①safer 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 ②curiosity. 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 ③permanent 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 ④unpredictably 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 ⑤caution rather than carelessness.

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.

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.

When you separate paper, plastic, glass, and cans, recycling centers can process each material more ①efficiently. 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. If items are mixed together ②carefully, finding what you need later becomes difficult. Likewise, mixing recyclables with ordinary trash makes the whole recycling process ③complicated. Many students believe that sorting trash takes too much time, but it actually requires only a few extra ④seconds. Therefore, learning these basic rules now helps you build a habit that ⑤benefits your entire community.

Every day, people throw away piles of ①used paper without thinking about where it goes. However, most of that paper does not have to end up in a landfill. Instead, it can travel to a recycling factory and become brand new paper again. First, workers collect old newspapers, boxes, and notebooks left in recycling bins. These papers are then soaked in water and turned into ②hard, mushy pulp. You can think of this process like breaking a cookie back into flour and water. For example, ink and small pieces of plastic are ③removed from the pulp during this stage. The ④clean pulp is pressed into thin sheets and dried in large machines. Therefore, a wrinkled old newspaper can be ⑤reborn as clean white paper. In contrast to throwing paper away, recycling it saves trees and reduces waste.

Accidents rarely wait for a doctor to be nearby, which is why basic first aid knowledge can make a ①critical 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 ②steady pressure to a bleeding wound or keeping an unconscious person's airway clear, can prevent a minor injury from becoming a life-threatening one. Waiting passively for an ambulance, rather than doing anything at all, is often the more ③dangerous choice, since every minute without basic care allows a treatable injury to worsen. Of course, first aid is never a ④substitute for professional medical treatment, and it should never replace an emergency call. Even so, schools that offer first aid training report that students respond far more ⑤nervously and effectively during real emergencies.

Every summer, lifeguards repeat the same warnings to swimmers, yet drowning remains one of the most common causes of accidental death among teenagers. Part of the problem is that _______________, which means bystanders may not realize help is needed until it is too late. Rip currents present a particularly deceptive threat, since the water's surface can appear calm even while a powerful current pulls a swimmer steadily away from shore.

Every plastic product carries a small recycling mark, but few students know what these marks mean. Each symbol _______________. For instance, the number one usually stands for clear plastic bottles, while the number five represents thicker containers like yogurt cups. Reading these marks is similar to reading nutrition labels on snacks, which tell you exactly what is inside. Without checking the label, you might buy something unhealthy by mistake. Likewise, throwing 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 be sorted separately. Therefore, taking a few seconds to check the mark before throwing something away makes recycling far more effective for everyone involved.

주어진 문장: In other words, the item keeps its basic shape but serves a completely different purpose. Have you ever thrown away an old pair of jeans simply because they no longer fit? ① Instead of discarding them, many people now turn old items into something new and useful. This creative process, called upcycling, transforms unwanted objects into products with greater value than before. ② For example, a worn pair of jeans can be cut and sewn into a sturdy bag or a small pouch. Old wooden pallets, once used for shipping, are often rebuilt into simple furniture such as tables and shelves. ③ However, upcycling differs from ordinary recycling, which usually breaks materials down before making something new. In upcycling, the original material keeps most of its form while gaining a fresh purpose. ④ Therefore, choosing to upcycle rather than throw items away can reduce waste significantly. ⑤ This small shift in thinking allows old objects to enjoy a meaningful second life.

This is precisely why traffic engineers insist that speed, not visibility, should determine how school zones are enforced. Around elementary schools, bright yellow signs mark what is known as a school zone, an area where drivers are required to slow down to reduce the risk of striking a child who might dart into the street without warning. ( ① ) Some drivers complain that the reduced speed limit wastes their time, especially when no children happen to be visible at that moment. ( ② ) This complaint misses an important fact about how children behave near traffic: young students often lack the judgment to predict how far a car will travel before it can stop. ( ③ ) They may step off the curb chasing a ball or a friend without checking either direction. ( ④ ) A car traveling even ten kilometers per hour slower gives a driver several extra seconds to brake, often the exact difference between a frightening near miss and a tragedy. ( ⑤ ) For this reason, cities have begun installing cameras that automatically fine drivers who ignore the posted limit near schools.
