Science labs feel far safer than they actually are, largely because the equipment looks harmless and the experiments are carefully ①planned by a teacher. This false sense of security leads some students ②to skip small precautions, such as wearing safety goggles for a "simple" experiment or tasting a substance out of curiosity. Chemical reactions, however, do not distinguish between a professional laboratory and a classroom; a small amount of the wrong substance ③splashed into an eye can cause permanent damage within seconds, regardless of how basic the experiment seemed. Teachers repeatedly emphasize ④to read each instruction before touching any material, since even a familiar-looking chemical can behave 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 ⑤have performed many times before.

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.

Every spring, our school holds an art exhibition in the main hallway, and this year I finally submitted a painting of my own. For weeks, I compared my work to my classmates' drawings and felt sure that mine was not good enough to hang beside theirs. My art teacher noticed my hesitation and said something I did not expect: _______________. On the morning the paintings went up, I walked past dozens of styles, from careful realistic portraits to messy, colorful abstractions, and none of them looked like mine. Standing in that crowded hallway, I finally understood that the exhibition's real purpose was not to rank the paintings, but to let students discover how many different perspectives could exist in a single shared space.

Our school's volunteer club, Helping Hands, tries to _______________. Each month, students visit a nearby nursing home and spend an afternoon talking with elderly residents. For example, they read newspapers aloud or just listen to old stories from the residents. In addition, members collect used books and toys from classmates and donate them to a community center downtown. Some students feel nervous before their first visit, unsure of what to say to strangers. However, most discover that a warm smile works better than perfect words. Therefore, the club's real goal is not just finishing hours for a report card. Instead, it teaches members that caring for others grows into a lasting habit, like watering a plant daily. By the end of the year, many students say the club changed how they see their community.

When temperatures drop below freezing overnight, an invisible layer of black ice can form on sidewalks that 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 _______________. Orthopedic doctors report a sharp rise in wrist and hip injuries every winter, most of them caused not by dramatic slips on icy hills but by a single unexpected step near a bus stop or a doorway.

Technology has changed the way many jobs are performed today. (A) As a result, workers now need to keep learning new tools throughout their careers. (B) A graphic designer, for instance, must understand digital software that did not exist twenty years ago. (C) Machines and computer programs now handle tasks once done entirely by people.

Whenever people discuss the future of reading, one debate never seems to end: e-books or paper books? (A) Fans of paper books, however, argue that something important is lost on a screen, since many readers say they remember a book's plot more clearly by recalling where a scene appeared on the page. (B) Supporters of e-books point out that a single device can hold thousands of titles, and readers can also change the font size or look up a word instantly. (C) Screens also invite distraction, since a single notification can pull a reader away from the story, and interestingly, most young readers do not choose one format forever.

At first, Minji did not know how to fix the tension she had caused during rehearsals. (A) Soon, other members began doing the same, and rehearsals felt warmer than before. (B) She decided to start each practice by praising one small thing a classmate had done well. (C) The next day, she tried her new idea, and the room grew quiet as everyone listened.

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.

Even a short glance downward, timed badly, is enough to miss an oncoming bicycle or a changing traffic light. Walking down a crowded street while staring at a phone screen has become such a common sight that it barely draws attention anymore, even though the habit turns a pedestrian into one of the least alert people on the sidewalk. ( ① ) Researchers who study attention describe this as a kind of tunnel vision: a person absorbed in a text message or a video processes only a narrow slice of the surrounding environment, filtering out approaching cars, uneven pavement, and other pedestrians almost entirely. ( ② ) 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. ( ③ ) What makes this danger especially difficult to address is that pedestrians rarely recognize the risk in the moment. ( ④ ) Unlike distracted driving, which is widely condemned, glancing at a phone while crossing the street still feels like a harmless habit to most people who do it every day. ( ⑤ )
