영어 모의고사 (자동 편성)

Before making a purchase, most online shoppers now read reviews ①written by previous customers rather than relying solely on advertisements. These reviews, posted by people who have no financial connection to the seller, often ②seem more trustworthy than promotional claims. Research shows that products with a large number of positive reviews ③sell significantly more than those with few or no reviews at all. However, fake reviews written by paid writers or even automated programs ④has become a serious problem, undermining consumer trust. To address this issue, several review platforms have begun ⑤using artificial intelligence to identify suspicious patterns.

When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers ①belonged only to a handful of government scientists. By the time he entered university, however, the space industry had changed dramatically, as private companies began ②launching satellites and building reusable rockets. Daniel studied aerospace engineering, ③drawing to the idea that space exploration was no longer limited to a few national agencies. During an internship, he helped design a small satellite ④intended to monitor crop health from orbit. He realized that the space industry now needed not only pilots and engineers but also data analysts and technicians ⑤familiar with international space regulations.

A smartwatch strapped to a runner's wrist can now do far more than simply count steps; it monitors heart rate variability, running form, and recovery time, then uses that data to suggest a training plan ①tailored to the individual rather than a generic weekly schedule. When the device detects signs of overtraining, such as an unusually high resting heart rate several mornings in a row, it may recommend a ②lighter workout or an extra rest day before fatigue turns into an actual injury. Amateur athletes often credit this kind of guidance with helping them train more ③consistently without pushing their bodies too hard. Sports scientists note an important caveat, however: a wrist-based sensor cannot fully capture the same physiological detail available in a professional lab, so its suggestions should be treated as an ④infallible medical judgment rather than a helpful guideline, particularly for anyone ⑤managing a chronic health condition.

A growing number of health apps now track steps, sleep, and heart rate throughout the day, quietly building a detailed picture of a user's physical condition without requiring a single visit to a doctor's office. By comparing this stream of data against patterns drawn from millions of other users, the app's algorithm can ①flag early warning signs, such as an irregular heartbeat, long before the person experiencing it would have noticed anything unusual on their own. For people living far from specialists or unable to afford frequent checkups, this kind of constant monitoring can feel like a genuine ②safety net. Doctors caution, however, that these apps are designed to ③diagnose illness, not merely to detect patterns, and that a worried user should always confirm any alarming reading with a professional rather than trusting an app's suggestion alone. Treating a wellness app as a ④substitute for medical expertise, they warn, can be just as risky as ⑤ignoring a warning altogether.

Psychologists have long studied a mechanism called the variable reward schedule, in which rewards arrive unpredictably rather than after every single action. Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. When someone posts a photo, they cannot predict exactly when likes will appear, nor how many they will eventually receive. This uncertainty triggers a small burst of dopamine each time the phone is checked, regardless of whether the result is disappointing or thrilling. Consequently, users often refresh their feeds compulsively, hoping the next check will finally bring a satisfying reward. What makes this troubling is that technology companies deliberately designed notification systems using insights borrowed from gambling research, rather than stumbling upon them by accident. Such practices raise serious ethical questions about manipulating users' brains for profit. Therefore, people must _______________.

A smart thermostat that learns a family's daily rhythm can lower the temperature automatically before everyone wakes up cold, while smart lights that follow a resident's schedule no longer need to be switched on and off by hand. Sensors collect data about temperature, motion, and light throughout the home, and an algorithm gradually learns which settings match each household's actual habits. Yet convenience comes with a trade-off that many households overlook: _______________.

Open a music streaming app on any given morning, and a personalized playlist is usually already waiting, assembled overnight from songs the algorithm predicts will match a listener's current mood. Listeners often praise the feature for introducing them to artists they never would have searched for on their own. Musicians, meanwhile, have mixed feelings about this shift in how audiences discover new music. A song that the algorithm decides not to promote may struggle to reach listeners no matter how well it was written, meaning 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 _______________.

This natural advantage, however, is only a starting point rather than a fixed ceiling. 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. ( ① ) 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 from that blood with remarkable efficiency. ( ② ) 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. ( ③ ) Interval training, which alternates short bursts of near-maximal effort with periods of recovery, has proven particularly effective at improving this measurement compared to steady, moderate-intensity exercise alone. ( ④ ) It is worth noting, however, that a high VO2 max does not guarantee success in competition, since factors such as running economy, pacing strategy, and mental resilience also play a decisive role in determining who actually crosses the finish line first. ( ⑤ )

주어진 문장: This is a significant shift from earlier generations, who often stuck with a single trusted brand for years. Generation Z, typically defined as those born between the late 1990s and early 2010s, approaches shopping quite differently from previous generations. ( ① ) Having grown up with smartphones and social media, they research products extensively online before making even small purchases. ( ② ) Unlike older generations, who often valued brand loyalty above all else, many members of Generation Z prioritize a company's values, switching brands easily if one no longer matches their beliefs. ( ③ ) They also tend to favor secondhand and resale platforms, viewing sustainability as an important factor rather than an afterthought. ( ④ ) Peer recommendations shared through short videos frequently carry more weight than traditional celebrity endorsements. ( ⑤ ) Businesses that fail to adapt to these preferences risk losing an entire generation of potential customers.
