Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle that ①governs when we feel alert and when we feel drowsy. This clock is regulated primarily by a tiny cluster of neurons in the brain that responds to light entering through the eyes. When morning sunlight strikes the retina, the cluster signals the body to ②suppress sleep hormones and raise body temperature, preparing us for activity. As evening approaches and light fades, the same mechanism triggers the release of melatonin, a hormone that ③promotes drowsiness. Because this rhythm evolved around the natural cycle of day and night, modern habits such as staying indoors under artificial light or working night shifts can push the internal clock ④out of sync with the external environment. Such misalignment does not simply cause tiredness; it has also been associated with digestive problems and ⑤heightened concentration, suggesting that timing matters as much as total sleep hours.

A ①shrinking number of teenagers are joining book clubs that exist only on their phones. These apps let users track how many pages they read each day, write short reviews, and join group chats about a chosen book. Some students say the apps make reading feel less ②lonely, because they can share their honest reactions the moment they finish a chapter instead of waiting for a weekly meeting. The apps also use gentle reminders and reading streaks to keep members ③motivated, turning a private habit into a small social game. However, a few teachers worry that constant notifications from a reading app can pull attention away from the book itself, since users may spend more time ④chatting about the story than actually reading it. Despite this concern, many students report that the sense of community keeps them reading books they would have quit halfway through if they had been reading completely ⑤alone.

Building a reading habit does not usually start with a big decision to read more. It often starts with very ①small, easy steps. Some students keep a book in their bag so that they always have something to read while waiting for a bus. Others choose a fixed time each day, like right before bed, and read for just ten minutes. These small routines work because they ②increase the effort needed to begin. Once a student sits down and opens a book, continuing to read the next page feels much ③easier than the first step of starting. Experts also suggest setting a very ④low daily goal, such as one page, instead of a strict page count that feels like homework. Over weeks, these tiny actions add up, and reading slowly becomes something the student simply does, rather than something the student has to ⑤force.

When people have no specific goal, they usually feel ①confused about where to start, and their interest fades within days. For example, a student who simply decides to study harder this year often loses direction because the plan is too ②vague. In contrast, a student who sets a ③clear goal knows exactly what to do every day. A clear goal also makes progress easy to measure, and noticing small improvements keeps people ④encouraged. Setting a specific goal is one of the most ⑤ineffective ways to build lasting motivation.

Desalination, the process of removing dissolved salts from seawater to produce fresh water, has increasingly been adopted by coastal regions facing chronic water scarcity. Most modern facilities rely on reverse osmosis, a technique in which seawater is forced through membranes whose microscopic pores block salt while letting water molecules pass. Because this method consumes far less energy than the thermal distillation once dominant in the industry, it has become the preferred choice for large-scale plants. Nevertheless, _______________. For instance, the process generates a concentrated byproduct called brine, which, when discharged without adequate dilution, can raise local salinity to levels that harm marine life. Pumping seawater through membranes at high pressure also demands substantial electricity, so plants powered by fossil fuels can worsen the emissions that intensify drought. Therefore, engineers increasingly argue that desalination should be treated not as a stand-alone remedy but as one component of a broader conservation strategy.

When a classmate began writing her diary entries in elaborate, flowing calligraphy instead of ordinary handwriting, I assumed she was simply trying to make her notebook look decorative. Curious, I asked her to teach me one afternoon, and I quickly discovered that calligraphy demands far more patience than I had expected. Every stroke has to be planned before the pen touches the paper, since a brush pen cannot be casually corrected once ink has already spread across the page. She told me that _______________. What began as decoration for her gradually became a kind of meditation, a rare part of her day when she could not multitask or hurry. I left that lesson with ink-stained fingers and a newfound respect for how much concentration a single beautifully written word can require.

Walking down a crowded street while staring at a phone screen has become such a common sight that it barely draws attention anymore. Researchers describe this as a kind of tunnel vision: a person absorbed in a text message processes only a narrow slice of the surrounding environment. 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. What makes this danger especially difficult to address is that _______________.

Anthropologist Robin Dunbar proposed a concept now known as Dunbar's number, suggesting that human beings can only maintain about one hundred fifty stable social relationships at any given time. This limit, he argued, comes from the size of the human brain, which restricts how many meaningful connections a person can cognitively manage. In contrast, many social media users today have hundreds or even thousands of online friends and followers, a number far exceeding what Dunbar's research predicts. However, having numerous digital contacts does not necessarily mean that all of these relationships are close or emotionally supportive. Most users, when asked, admit that they interact regularly with only a small fraction of their total followers, while the rest remain largely unnoticed. Therefore, Dunbar's number reminds us that ___________.

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. (A) 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. (B) Safety experts consistently teach the same three steps: drop to the ground, take cover under sturdy furniture, and hold on until the shaking stops. (C) 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 debris often causes more injuries near exits and windows.

주어진 문장: Such admiration is common, for instance, toward chess grandmasters, medical diagnosticians, or professional musicians who seem to recall vast bodies of specialized knowledge without visible strain. When people encounter an individual who appears to memorize enormous quantities of specialized information effortlessly, they often assume that person possesses an innate gift. ( ① ) Cognitive psychologists, however, contend that such feats rarely stem from raw talent alone. Instead, such feats arise from a learned skill known as chunking, whereby scattered pieces of information are consolidated into larger, meaningful units. ( ② ) A landmark study of chess players demonstrated this principle. When shown a board arranged according to plausible game positions, grandmasters reproduced the layout perfectly. ( ③ ) Yet when the same pieces were scattered randomly, their performance collapsed to the level of novices. This pattern reveals that expert memory is not larger in raw capacity but is instead organized around patterns accumulated through years of deliberate practice. ( ④ ) If chunking, rather than innate aptitude, underlies expert performance, then educators should stop treating talent as fixed and destiny-bound. ( ⑤ ) Curricula ought to be redesigned to cultivate pattern recognition explicitly, since doing so would grant far more students access to expertise once presumed reserved for the naturally gifted.
