영어 모의고사 (자동 편성)

When Minji was in ninth grade, she ①posted a joking comment mocking a classmate's photo, never imagining anyone would remember it later. Three years passed, and she nearly forgot the comment ②existed, buried among hundreds of old posts. Last spring, she applied to join her school's student council, ③hoping her leadership experience would impress the selection committee. During the interview, however, one teacher mentioned ④having seen an old, unkind comment under Minji's name while reviewing applicants' profiles. She understood that digital footprints rarely disappear completely, even when the original posts ⑤was removed, because screenshots and memories often outlast the content itself.

As millions of people now earn income through delivery apps and ride-hailing platforms, questions about their legal status ①have become increasingly urgent. Most platform workers are classified as independent contractors rather than employees, ②which means they are not entitled to minimum wage guarantees or paid sick leave. Companies favor this arrangement because it allows them ③to avoid the costs associated with hiring full employees. Worker advocates, however, argue that many platform workers ④depend on these jobs as their primary source of income. Several countries have recently begun reconsidering their labor laws, ⑤proposed new categories that would grant workers some protections.

Building brand loyalty has traditionally been considered one of the most valuable goals in marketing, since loyal customers tend to spend ①more and recommend products to others. However, some critics argue that these programs manipulate consumers into staying with a brand out of habit rather than genuine ②satisfaction. Genuine loyalty, they contend, should be earned through consistent quality and honest treatment of customers, not through ③artificial incentives that merely delay a customer's departure. Furthermore, excessive focus on retaining existing customers can cause companies to ④neglect innovation, since they assume loyal buyers will continue purchasing regardless of improvements. Relying solely on loyalty programs without addressing underlying product quality may ultimately ⑤succeed.

Automation is transforming labor markets more ①quickly than economists predicted a decade ago. Factories once staffed by hundreds of workers now rely on robotic arms that assemble products with remarkable ②precision. This shift does not simply eliminate jobs; it also creates roles that never existed before, so technicians who maintain robotic equipment are now in high ③demand. Companies that invested early in automation often report steady increases in productivity, since machines handle repetitive tasks while employees focus on ④creative problem-solving. Without proper retraining support, the benefits of automation may not be shared fairly, ⑤narrowing inequality between skilled and unskilled labor.

Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. This theory explains that every habit begins with a cue, a signal that tells the brain to start an automatic behavior. The brain then performs a routine, which is the action itself, whether physical or mental. Finally, the brain receives a reward, a positive feeling that makes it want to repeat the same behavior. For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run without conscious thought. Because this loop operates automatically, breaking a bad habit requires ___________. Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.

As the job market continues to change, experts have identified several core competencies that will matter most in the future. (A) Beyond such technical knowledge, however, employers increasingly value problem-solving and adaptability when evaluating candidates. (B) Technical literacy, including basic coding and data analysis, has become nearly as fundamental as reading and writing once were. (C) Communication skills matter as well, since many future jobs will require collaborating with both human colleagues and intelligent systems.

During sleep, the brain does not simply rest; it actively reorganizes the day's experiences into lasting memories through a process called consolidation. (A) Sleep researchers have demonstrated this effect experimentally: participants who slept after learning a list of word pairs recalled more items the next day than participants who remained awake instead. Crucially, the benefit was not limited to simple recall; sleep also seemed to help participants extract general patterns from the material, suggesting that consolidation involves more than passive storage. (B) Newly formed memories are initially fragile and stored primarily in a brain region called the hippocampus, which has limited long-term capacity. (C) While a person sleeps, particularly during the deep stages of non-REM sleep, neural activity replays these fresh memory traces in rapid, compressed sequences, gradually transferring the information to the cortex for more durable, long-term storage. This replay strengthens the connections between neurons that encoded the original experience, making the memory more resistant to interference from unrelated events the following day.

VO2 max, defined as the maximum volume of oxygen a person's body can consume and use during intense exercise, is widely regarded as one of the best single indicators of cardiorespiratory fitness. (A) Elite endurance athletes typically post VO2 max values far higher than those of untrained individuals, reflecting hearts that pump larger volumes of blood and muscles that extract oxygen with remarkable efficiency. (B) While genetics accounts for a substantial portion of an individual's potential VO2 max, consistent aerobic training can still raise the measurement considerably over months of dedicated effort. (C) It is worth noting, however, that a high VO2 max does not guarantee success in competition, since other factors such as pacing strategy and mental resilience also play a decisive role.

주어진 문장: This flexibility, however, comes with a hidden cost that many workers overlook. Remote work has moved from a rare privilege to a common practice for millions of employees worldwide. ( ① ) Many companies that once required workers to commute daily now allow them to complete tasks from home. ( ② ) Supporters argue that remote work increases productivity, since employees avoid long commutes and distracting office environments. ( ③ ) It also allows companies to hire talented people regardless of where they live, widening the pool of candidates. ( ④ ) Critics, however, worry that remote work weakens teamwork and makes it harder for new employees to learn from experienced colleagues. ( ⑤ ) Without regular face-to-face interaction, some workers feel isolated and struggle to build strong professional relationships.

One of the clearest examples of this involves a specific protein that stimulates the growth of new brain cells. Exercise does far more than strengthen muscles and the heart; it also produces measurable changes within the brain itself. ( ① ) During sustained physical activity, the body releases a protein called brain-derived neurotrophic factor, which supports the growth of new neurons and strengthens connections between existing ones, particularly in regions associated with memory and learning. ( ② ) Studies comparing physically active students to sedentary peers have repeatedly found that the active group performs better on tests of attention and problem-solving, even when the exercise session ends well before the test begins. ( ③ ) Researchers believe that exercise increases blood flow to the brain, delivering oxygen and nutrients more efficiently, while also reducing levels of stress hormones that can interfere with clear thinking. ( ④ ) Interestingly, aerobic activities such as running or swimming appear to produce more pronounced cognitive benefits than purely strength-based training. ( ⑤ )
