Many people throw away items that they no longer need. However, some students have started to buy and sell used goods instead of throwing them away. This practice, often called secondhand trading, takes place at flea markets or through simple online apps. When you buy a secondhand book or a used bicycle, you save money and reduce waste at the same time. For example, a jacket that no longer fits your older sibling can become a treasure for someone else. Giving an old item to a new owner is like giving a toy a second life. In contrast, throwing away useful items increases the amount of trash that ends up in landfills. Therefore, secondhand trading, which requires little effort, _______________. Small choices like this can make a big difference for our planet.

Yuna bought a disposable coffee cup every morning on her way to school. She never thought about where those cups ended up after she threw them away. One day, her science teacher showed the class a photo of a beach covered with plastic cups and bottles. Yuna felt shocked because she realized _______________. That evening, she found an old tumbler hidden in a kitchen drawer and decided to use it every day. At first, carrying the tumbler felt inconvenient, and she often forgot to bring it to school. However, she kept a reminder note on her bag, which helped her remember it each morning. Within a month, using the tumbler had become as natural as brushing her teeth. Her friends noticed the change and asked where she had bought the tumbler.

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.

Stairs seem too ordinary to be dangerous, which is why many people treat them carelessly, texting, carrying an armful of books, or skipping two steps at a time. (A) Familiarity encourages 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. (B) Safety officials recommend a few unglamorous habits: keep one hand free, use the handrail, and turn on the light before stepping onto a dark staircase. (C) Emergency room records tell a different story: falls on stairways send more people to the hospital each year than almost any other household accident.

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.

Many readers assume that once they finish a book, there is no reason to open it again. (A) Some students who reread their favorite novel report that it feels almost like reading a different book, because they now understand the characters' motives more deeply. Teachers therefore encourage students not to rush toward new titles alone, but to occasionally return to a book they already loved, since a second visit often teaches more than the first. (B) Once the ending is already known, a second reading frees the mind to notice smaller things, such as a clever hint the author placed early in the story or a change in a character's tone. (C) Yet teachers who study reading often disagree, arguing that a second reading can reveal details a first reading misses completely. During a first reading, most of a student's attention goes toward simply following the plot, wondering what will happen next.

Looking back at the goals I set last New Year, I can now see how much actually changed over the year. (A) I did not finish all twelve books I had planned to read, but six was still an improvement from the previous year. (B) Saving money turned out to be the hardest part, since unexpected expenses kept appearing throughout the year. (C) In addition, my exercise habit became a pleasant surprise, as jogging twice a week slowly turned into a daily morning routine.

This eagerness to get moving is understandable, but it can come at a real physical cost. 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. ( ① ) 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 rather than minutes. ( ② ) Coaches often compare an unwarmed muscle to a cold rubber band that snaps rather than stretches under sudden pressure. ( ③ ) 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 on a gym floor or an outdoor field. ( ④ ) Reporting a minor pain immediately, rather than pushing through it to finish a game, also prevents a small issue from becoming a repeated injury that lingers for an entire season. ( ⑤ )

Once the initial tremor passes, however, the danger does not simply disappear. Earthquakes strike without any warning, which is exactly why the seconds immediately after the shaking begins matter more than any other moment in an emergency. ( ① ) Safety experts consistently teach the same three steps: drop to the ground, take cover under sturdy furniture, and hold on until the shaking stops. ( ② ) Many people instinctively want to run outside during a quake, imagining that open space is always safer 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. ( ③ ) Furniture that seems merely inconvenient during a fire drill, such as a heavy desk, becomes a lifesaving shield when the ceiling above begins to crack. ( ④ ) After the shaking stops, experts warn that the greatest remaining danger is often a damaged structure rather than a second earthquake. ( ⑤ ) So calmly checking for hazards before moving is just as important as reacting quickly at the first tremor.

In their view, reading a caption or a text message still counts as reading, even if it looks very different from reading a novel. Many teachers and parents worry that today's teenagers are losing the ability to read long, complex texts. ( ① ) National test scores show a slow decline in reading comprehension over the past ten years, and some experts blame smartphones and short videos for shortening students' attention spans. ( ② ) Other researchers disagree with this simple explanation. ( ③ ) They point out that teenagers today read constantly, just in different forms, such as text messages, captions, and online articles. ( ④ ) According to this view, the real problem is not that students read less overall, but that they rarely practice reading long passages without any interruption. ( ⑤ ) A team of researchers recently found that students who read at least one full book every month scored noticeably higher on comprehension tests than students who mainly read short online posts, which suggests that the format of reading, rather than simple screen time, may be the more important factor behind the changing scores.
