Adaptive learning apps promise something no traditional classroom can easily offer: a lesson plan ①that adjusts itself to each individual student in real time. As a student answers practice questions, the app tracks which concepts are mastered and which remain shaky, then quietly ②reshuffles the next set of problems to target the weaker areas. Early studies suggest that this personalized pacing can help struggling students ③catch up faster than a one-size-fits-all worksheet ever could. However, critics caution that an app cannot replace the encouragement, humor, and flexibility a human teacher brings to a lesson, especially when a student ④frustrating rather than simply behind. There is also a subtler concern: students who grow used to instant, algorithm-generated feedback may struggle later with the slower, more ambiguous kind of feedback that real-world tasks and mentors typically ⑤provide.

Highlighting an awkward sentence and instantly seeing three smoother alternatives has become a routine part of writing for many students, thanks to AI writing assistants built into word processors and browsers. These tools check grammar and spelling, of course, but the more advanced versions go further, suggesting clearer phrasing, ①flagging repetitive words, and even adjusting tone to sound more formal or more casual depending on the purpose. Teachers generally ②welcome the grammar and spelling support, since it frees up class time to focus on argument and structure rather than comma placement. Concerns ③shrink, however, around the tone and phrasing suggestions, which can gradually nudge every student's writing toward a similar, polished style, making it harder to tell an individual voice from a suggestion generated by the same underlying model. Some schools have begun asking students to submit an early draft alongside the final version, specifically to ④preserve evidence of a student's own ⑤original voice.

Aerobic exercise, such as jogging, swimming, or cycling at a steady pace, strengthens the heart by forcing it to pump ①larger volumes of blood with each beat. Over weeks of consistent training, the heart gradually enlarges and becomes more efficient, meaning it can deliver the same amount of oxygen to working muscles while beating ②fewer times per minute. This adaptation explains why trained athletes often have a much ③lower resting heart rate than sedentary individuals of the same age. Beyond the heart itself, aerobic activity encourages the body to build new capillaries within muscle tissue, ④worsening the delivery of oxygen and nutrients at a cellular level. Researchers have also found that regular aerobic exercise ⑤reduces inflammation throughout the body and improves the way cells respond to insulin.

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 ___________.

Long before a user finishes typing a sentence, the keyboard on most smartphones has already begun guessing what word comes next. This feature relies on a language model trained to notice which words commonly follow one another, so it can offer a shortlist of likely candidates, saving users countless keystrokes over the course of a day. This constant personalization, however, creates a subtle side effect that few users notice: some linguists worry that _______________.

Psychologist John Suler proposed a concept called the online disinhibition effect, describing how people behave differently on the internet than they do face to face. Because usernames often hide real identities and screens create physical distance from others, individuals feel freer to express themselves without immediate social consequences. This freedom can be beneficial, allowing shy people to share honest feelings they would normally hesitate to reveal in person. However, the same anonymity frequently produces a darker outcome, encouraging users to post cruel comments they would never say to someone's face. Malicious remarks left under celebrities' photos or news articles illustrate how quickly this behavior can spread once a few users set the tone. Such comments often cause severe emotional harm to the people who receive them. Therefore, users must _______________.

Every day, email providers quietly block billions of unwanted messages before they ever reach a user's inbox. The filter examines each incoming message for suspicious patterns, including certain keywords, unusual sender addresses, and formatting tricks. What makes the system effective is that it keeps learning after launch: whenever a user marks a message as spam, that action becomes new training data, sharpening the filter's future decisions. This creates a constant back-and-forth, since spammers study which messages get blocked and then adjust their wording to slip through again. As a result, _______________.

The concept of energy management has gained popularity among workplace researchers who study how people sustain productivity throughout the day. (A) For this reason, experts recommend that people identify the hours when they naturally feel most alert and schedule their most demanding tasks during those windows. (B) Unlike time, which passes at the same rate for everyone, personal energy fluctuates throughout the day depending on factors such as sleep and nutrition. (C) Simple or repetitive tasks, on the other hand, can be handled during low-energy periods without much loss in quality.

Treating only one side of this equation, therefore, often leaves the other free to sustain the sleeplessness on its own. Insomnia is rarely caused by a single factor; it usually emerges from an interaction between psychological stress and physiological arousal that keeps the body from settling into sleep. ( ① ) A common trigger is what researchers call cognitive hyperarousal, in which the mind continues to race with worries about work, relationships, or even the inability to sleep itself, creating a frustrating cycle where anxiety about insomnia becomes a cause of insomnia. ( ② ) At the same time, the body's stress response system can become chronically activated, releasing hormones such as cortisol that keep heart rate and body temperature elevated at night, both of which interfere with the natural drop in arousal needed to fall asleep. ( ③ ) Poor sleep habits, including irregular bedtimes and excessive screen use before bed, can further weaken the body's internal signals for sleep onset. ( ④ ) Because these psychological and physiological factors reinforce one another, effective treatment for chronic insomnia addresses both the racing mind and the underlying pattern of physical tension, rather than relying on medication alone. ( ⑤ )

주어진 문장: This misconception, sometimes called the twenty-one-day myth, has been repeated so often that many people accept it without question. Many people believe that a new habit becomes automatic after only twenty-one days, but researchers who examined real behavior found a different number. ( ① ) This project, called the 66-day habit formation study, tracked volunteers who tried to adopt a new daily habit, like drinking water with lunch. ( ② ) Researchers measured how automatic each action felt over time and found that habits needed an average of sixty-six days to become effortless. ( ③ ) Yet the actual time varied widely, ranging from about eighteen days for simple habits to over two hundred days for difficult ones. ( ④ ) This wide range explains why the popular twenty-one-day claim, though easy to remember, rarely matches real experience. ( ⑤ ) For instance, flossing might feel automatic within a few weeks, while jogging every morning may take months to feel natural. The study's central lesson is that patience matters more than speed when building lasting habits.
