Physical education class often feels like the one period of the day when students can finally move freely, which sometimes leads them ①to skip the warm-up routine that teachers insist on before any real activity begins. Cold muscles, however, are noticeably ②less 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 rather than minutes. Coaches often compare an unwarmed muscle to a cold rubber band that ③snap rather than stretches under sudden pressure. 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 ④raises the chance of a twisted ankle on a gym floor or an outdoor field. Reporting a minor pain immediately, rather than pushing through it to finish a game, also ⑤prevents a small issue from becoming a repeated injury that lingers for an entire season.

When temperatures drop below freezing overnight, an invisible layer of black ice can form on sidewalks ①that look perfectly dry, catching even careful walkers off guard. Unlike a visibly icy patch, black ice reflects almost no light and blends into ordinary pavement, which is why so many falls happen on stretches that pedestrians ②would never suspect. Orthopedic doctors report a sharp rise in wrist and hip injuries every winter, most of them ③causing not by dramatic slips on icy hills but by a single unexpected step near a bus stop or a doorway. Walking with shorter, flatter steps and keeping the hands free rather than in pockets can ④help a person regain balance quickly if a foot suddenly slides. Choosing shoes with textured rubber soles rather than smooth ones also makes a difference, since even a small increase in grip can ⑤prevent a fall before it begins.

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.

Minjun used to leave half of his lunch tray full of untouched rice and vegetables every day. Last spring, his class started a campaign called "Clean Plate Day" to reduce food waste. At first, Minjun thought the campaign sounded boring and unnecessary for someone like him. However, his teacher explained that leftover food thrown away every day adds up to a huge amount of waste. She compared uneaten food to _______________. This comparison surprised Minjun because he had never thought about food that way before. He decided to take only what he could finish and to try new vegetables slowly. Within a few weeks, his tray was almost always empty, and he felt proud of the change. Other students noticed his effort and began doing the same thing.

A loud, jarring alert sound interrupting a phone's normal notifications usually means one thing: a government agency has issued an emergency text to everyone in a specific area, warning of anything from a flash flood to a missing child. These messages are designed to reach people instantly, without requiring anyone to download an app or subscribe to a service in advance, since _______________. Some residents complain that the alerts arrive too frequently or for events that feel minor, leading a small number of people to silence the notifications altogether.

Teaching children to be cautious around strangers used to rely mainly on a single blunt warning: never talk to people you do not know. (A) A more effective approach focuses on specific situations rather than people in general, teaching children to recognize behavior that feels wrong, such as an adult asking a child to keep a secret from parents. (B) Child safety experts now argue that this advice is too simple to be useful, since most children will inevitably need to interact with unfamiliar adults. (C) Role-playing these scenarios in advance helps children respond quickly under pressure, rather than freezing because the situation feels unfamiliar and confusing.

When someone's heart suddenly stops beating, the brain begins 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. (A) Studies show that a person who receives CPR immediately from someone nearby is far more likely to survive than one who waits for professional help to arrive. (B) Despite this, many people hesitate to start chest compressions, worried that they might break a rib or make the situation worse. (C) Medical instructors respond to this fear: a cracked rib heals, but a brain deprived of oxygen for too long does not.

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. (A) 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. (B) Some drivers complain that the reduced speed limit wastes their time, especially when no children happen to be visible at that moment. (C) 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.

Seatbelts are so woven into the experience of riding in a car that many passengers buckle them without thinking, yet a surprising number of teenagers still skip them for short trips, assuming that a five-minute drive to a friend's house does not carry much risk. (A) In a collision, a body traveling at a moderate speed continues moving forward at that same speed until something stops it, and without a seatbelt, that something is often the windshield or the dashboard. (B) Traffic safety data tell a different story: most fatal crashes occur within a few kilometers of home, on roads drivers know so well that they let their guard down. (C) A seatbelt spreads the force of a sudden stop across the stronger parts of the body, such as the hips and chest, instead of concentrating it on the head and neck.

None of this design effort matters, however, if a person has simply stopped paying attention altogether. Safety signs surround us so constantly, from a yellow diamond warning of a curve ahead to a red octagon commanding a full stop, that most people stop consciously reading them soon after learning to drive. ( ① ) 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 failed at its purpose. ( ② ) Colors and shapes are chosen deliberately rather than randomly: red almost universally signals danger or prohibition, yellow signals 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. ( ③ ) Symbols replace text wherever possible for the same reason, allowing a running figure or a flame icon to communicate instantly to someone who may not speak the local language. ( ④ ) Ignoring a familiar sign because it has become part of the background remains one of the most common causes of accidents in public spaces. ( ⑤ )
