A biosensor works by pairing a biological component, such as an enzyme or antibody, with an electronic device that ①convert a biological reaction into a signal a computer can read. When the target molecule, whether glucose in blood or a trace of a pathogen, ②binds to the biological component, it triggers a small measurable change that the device translates into a readable number. This design has already transformed diabetes management, ③letting patients monitor blood sugar continuously through a small sensor worn under the skin rather than pricking a finger several times a day. Engineers are now racing to extend the same principle ④to detect subtler targets, from cancer cells circulating in the bloodstream to trace contaminants in drinking water. The central challenge is not detecting the target but doing so reliably outside a controlled laboratory, since a sensor that performs well on a clean lab bench can behave erratically once ⑤exposed to a real body or a real river.

Last January, Minji ①deciding that she would run three kilometers every morning before school. For the first week, she woke up early and ②ran happily, feeling proud of her new habit. However, after a few cold mornings, she began oversleeping, and soon she stopped running altogether. One evening, her older brother asked her why the plan ③had failed, and together they looked closely at her daily schedule. They realized that running before sunrise in freezing weather ④had been too difficult to maintain. So Minji changed her plan and decided ⑤to run after school instead, when the weather was warmer.

Our school's book club, Page Turners, meets every Wednesday to discuss a book the members ①chose. At the start of each month, students suggest titles and vote to pick one. This way, everyone feels some ownership over what the club reads next. Before each meeting, members read several chapters and ②prepare a few questions. During the meeting, the leader opens discussion by ③asking a question about the story's main idea. Then members take turns ④sharing their opinions, even when they disagree with each other. For example, students once argued for a long time about a character's difficult choice. Such debates, though sometimes loud, help members understand different points of view. At the end of the semester, the club holds an event ⑤recommending favorite books.

Many students assume that perfectionists work harder than everyone else, but psychologists describe a puzzling pattern ①called the perfectionism-procrastination cycle. This term describes how an intense fear of imperfect work ②cause people to delay starting a task rather than begin it. Because perfectionists set impossibly high standards, they often feel anxious before they even begin, and the task feels ③overwhelming. They then postpone the work to avoid ④facing their own unrealistic expectations, even though delay only increases their stress later. For example, a student writing a research paper might spend hours reorganizing notes instead of composing a single sentence that ⑤feels good enough.

Willpower is like a muscle that becomes ①tired after being used too much, so people often run out of self-control by the end of a busy day. Many resolutions are unrealistic from the beginning, since people set goals that are far too ②easy to reach in a short time, and when a goal feels impossible, people quickly ③lose motivation and stop trying. Most resolutions do not offer any ④immediate reward, so people find it hard to stay motivated without seeing fast results. Understanding these reasons can help people design goals that are more ⑤realistic and rewarding.

Psychologist Leon Festinger introduced social comparison theory, which explains that people evaluate their own abilities and opinions by comparing themselves with others. According to this theory, individuals engage in upward comparison when they measure themselves against someone who appears more successful, attractive, or accomplished. Social media platforms, filled with carefully edited photos and exaggerated achievements, provide endless opportunities for this kind of comparison. For instance, a teenager browsing vacation pictures posted by classmates may begin to feel that her own ordinary life is somehow inadequate. Unlike comparing oneself with someone in a similar position, which can sometimes boost confidence, upward comparison frequently triggers envy, dissatisfaction, and lower self-esteem. Researchers have found that frequent upward comparison online is linked to higher depression and anxiety. Consequently, this theory helps explain why ___________.

Water looks endless when it flows from the tap every morning, but clean water is actually a limited resource that we must protect carefully, since many families waste water without even noticing it. (A) Fixing a leaking faucet, which many people ignore, can also save hundreds of liters every month, since saving water is like keeping money in a savings account for the future. (B) For example, leaving the tap running while brushing your teeth can waste several liters of water, but turning off the tap during that time saves a surprising amount of water each day. (C) Taking a shorter shower is another easy habit that reduces water use significantly, and small changes like these can make a real difference over time.

주어진 문장: These various booths give every member a chance to show what they have practiced throughout the year. Every October, Greenfield High School holds a festival that gives every club a chance to shine. ① This year's festival will take place on October 15th, running from nine in the morning until four in the afternoon. ② Clubs that want to run a booth must apply to the student council by October 1st, since space in the gym is limited. ③ The science club will present simple experiments that are both safe and exciting to watch. The art club, meanwhile, will display paintings that members have created throughout the semester. ④ The cooking club plans to sell snacks prepared by its own members, and all the profits will be donated to a local shelter. ⑤ Because many visitors are expected, teachers will supervise each booth carefully to keep students safe. Anyone curious about club life is warmly encouraged to visit and enjoy the festival.

주어진 문장: This was her very first trip to the region, so she had nothing to compare the scene to except old photographs taken by earlier scientists. A documentary director named Mira first traveled to a remote Arctic glacier to film its towering cliffs of blue ice, which seemed frozen in time. ( ① ) Standing before the massive wall, she assumed such an enormous structure could hardly change within a lifetime. ( ② ) Five years later, however, she returned to the very same coordinates, expecting her camera to capture an identical scene. ( ③ ) Instead, she discovered that the glacier had retreated so dramatically that the ice cliffs, once visible from her original position, had nearly disappeared, leaving bare rock and pools of meltwater behind. ( ④ ) Comparing the two sets of footage side by side, Mira realized that a transformation she had expected to take centuries was actually happening within a single decade. ( ⑤ ) This encounter convinced her that climate change, which she had previously regarded as a distant statistic, was in fact an urgent process reshaping landscapes before her eyes.

주어진 문장: This is because the brain naturally pays more attention to things that are connected to a person's goals. Many students who reach their goals share one habit: they picture the goal clearly before they even start working. ( ① ) This process, called visualization, means imagining a goal in detail, often by drawing pictures or writing specific descriptions. ( ② ) For example, a student who dreams of studying abroad might make a board filled with photos of a foreign campus and a list of steps to get there. ( ③ ) Seeing these images every day keeps the goal fresh in mind and reminds the student why the effort matters. ( ④ ) Visualization also helps people notice small opportunities they might otherwise miss. ( ⑤ ) In addition, picturing success in advance can lower anxiety, because the mind grows familiar with the process instead of fearing an unknown outcome.
