Scientists have identified certain gene variants that ①appear more frequently among elite endurance athletes than among the general population, along with a separate set that seems to favor explosive, power-based sports such as sprinting. One frequently studied variant, for instance, ②influences the proportion of slow-twitch versus fast-twitch muscle fibers a person naturally develops, a ratio that shapes whether a body leans toward endurance or explosive power. However, researchers caution strongly against ③interpreting these findings as evidence that athletic greatness is simply inherited. Even athletes who carry every favorable variant identified so far still require years of disciplined training ④to translate that genetic potential into actual performance, and many elite competitors lack some of these supposedly advantageous variants altogether. Genetics may set a rough ceiling on an individual's ultimate potential, but where any particular athlete lands within that range ⑤depend overwhelmingly on training quality, nutrition, coaching, and sheer determination.

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.

Our photography club meets every Thursday, and our advisor always ①repeats the same instruction before we leave campus: put the camera down for the first ten minutes and simply look around. At first this rule frustrated me, since I ②had join the club specifically to take pictures, not to stand around empty-handed. Over time, though, I noticed that the members who followed her advice most closely ③tended to bring back the most interesting photographs. Instead of snapping dozens of rushed shots of the first flower or building they saw, they waited for a specific moment and ④captured only that. A camera, our advisor explained, cannot teach a person what is worth noticing; it can only record what the photographer has already ⑤decided matters.

Traditional industrial systems have relied on a linear model of production, in which raw materials are extracted, transformed into goods, and eventually discarded as waste. This approach treats natural resources as if ①unlimited and disposal as if costless. A circular economy proposes an alternative framework in which materials are kept in continuous use through reuse, repair, and recycling, thereby ②reducing the extraction of virgin resources. Central to this model is the notion that waste, rather than being an inevitable byproduct, can be redesigned as a resource for another process, much as fallen leaves nourish the trees that shed them. For example, manufacturers design products so that components can be disassembled and reused in new items once their original function ends. Some companies also lease equipment instead of selling it outright, retaining responsibility for refurbishment. Because such practices lessen dependence on finite raw materials, they ③increase the environmental damage caused by mining. Consequently, the circular economy is increasingly regarded as a ④viable economic strategy that ⑤conserves resources for future generations.

When people evaluate their personal contribution to water scarcity, they often consider only the water that flows directly from household taps, overlooking a far larger quantity consumed indirectly through the goods they purchase. The water footprint, a concept that extends this ①broad view, measures the total volume of freshwater used to produce the goods and services an individual or a nation consumes. Central to this concept is the notion of virtual water, the water embedded ②invisibly within a product, from irrigating cotton fields to livestock raised for meat. For instance, producing a kilogram of beef can require several thousand liters of water, whereas a kilogram of vegetables typically demands a fraction of that amount. Nations that import water-intensive goods rather than producing them domestically are importing virtual water from regions that may face ③severe shortages. Critics caution, however, that focusing ④exclusively on aggregate volume can mislead policymakers, since a liter of water drawn from a region suffering drought carries far greater consequences than one drawn from a water-⑤abundant area.

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. 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. The project leader solved this by _______________. Beginners filled in wide open skies, while experienced painters added fine details like veins on leaves or shadows under birds. 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.

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. (A) 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. (B) 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. (C) What makes this danger especially difficult to address is that pedestrians rarely recognize the risk in the moment; unlike distracted driving, which is widely condemned, glancing at a phone while crossing the street still feels like a harmless habit.

For many years, comic books and graphic novels were seen as a lazy alternative to real reading. (A) Recent research, however, tells a more complicated story, since graphic novels actually require readers to combine written text with visual clues. (B) Parents and teachers often worried that pictures did the work that words should do, leaving young readers with weaker vocabulary and imagination. (C) Rather than replacing traditional reading, graphic novels appear to work best as a bridge that leads students toward it.

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.

This is because a person's interests and strengths can change over the years. Many students take a career aptitude test at some point in high school. ( ① ) This test is designed to measure a person's interests, strengths, and personality traits. ( ② ) It does not simply tell students which job to choose; instead, it helps them understand themselves better. ( ③ ) For example, a student who enjoys solving problems might discover a hidden interest in engineering. ( ④ ) However, the results should be used only as a guide, not as a final answer. ( ⑤ ) Therefore, students should treat the test as a useful starting point, not a fixed decision.
