영어 모의고사 (자동 편성)

Jihun made a resolution ①to study English for two hours every day. For the first three days, he studied exactly as planned and ②felt proud of himself. However, on the fourth day, he skipped his study time because he was too exhausted, and within a week, his resolution had disappeared. ③Feeling disappointed, Jihun talked to his older sister about it, and she suggested that he ④try a smaller, more realistic goal instead of a large one. Following her advice, he changed his plan to studying English for only twenty minutes each night, and this small goal felt less overwhelming, so he managed ⑤keeping it every day for a month.

Many large companies now rely on artificial intelligence ① to screen job applications before a human ever sees them. These systems promise efficiency, scanning thousands of resumes in seconds and ranking candidates according to patterns ② drawn from previous hiring decisions. However, this reliance on historical data creates a troubling risk. If a company's past hiring favored a particular group, the algorithm may learn to treat that pattern as a marker of success and quietly reproduce it, even when no one ③ intending discrimination. Unlike a human interviewer, the system offers no explanation for its choices, which makes the bias difficult ④ to detect until an outside audit reveals it. Some researchers argue that fairness cannot be added afterward; it must ⑤ be built into the system's design from the very beginning.

Building brand loyalty has traditionally been considered one of the most valuable goals in marketing, since loyal customers ①tend to spend more and recommend products to others. Companies invest significant resources in loyalty programs, ②offering points, discounts, and exclusive access to encourage repeat purchases. Genuine loyalty, critics contend, should be earned through consistent quality and honest treatment of customers, not through artificial incentives that merely ③delays a customer's departure. Furthermore, excessive focus on retaining existing customers can cause companies ④to neglect innovation, since they assume loyal buyers will continue purchasing regardless of improvements. Relying solely on loyalty programs without addressing underlying product quality may ultimately ⑤backfire.

Soyeon joined an online study group chat where dozens of students ①planned a class project together every evening. When one member suggested ②skip a required survey step to save time, several others quickly agreed, and no one raised any objections. Soyeon privately worried that skipping the survey might ③weaken their project, but seeing everyone else nodding along, she stayed silent rather than risk sounding difficult. The group proceeded confidently, convinced their shortcut was harmless, until their teacher ④pointed out serious gaps once the project was submitted. She realized that the chat's friendly, unified atmosphere had actually ⑤discouraged critical thinking, making poor decisions feel completely normal at the time.

Have you ever wondered why some people stay motivated while others give up quickly? The answer often lies in whether they have a clear goal. When people have no specific goal, they usually feel confused about where ①to start, and their interest fades within days. For example, a student who simply decides ②to study harder this year often loses direction because the plan is too vague. In contrast, a student who sets a clear goal, such as raising an English score by ten points, ③knows exactly what to do every day. This clarity creates strong motivation because the brain naturally ④focus on a clear target. A clear goal also makes progress easy to measure, and noticing small improvements keeps people ⑤encouraged to continue.

Aerobic exercise, such as jogging, swimming, or cycling at a steady pace, strengthens the heart by forcing it to pump ① larger 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 ② fewer times per minute. This adaptation explains why trained athletes often have a much ③ lower 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, ④ worsening the delivery of oxygen and nutrients at a cellular level. Researchers have also found that regular aerobic exercise ⑤ reduces inflammation throughout the body and improves the way cells respond to insulin.

More and more teenagers today dream of starting their own business someday. This growing interest is partly due to the internet, which makes it ①easy to reach customers without a physical store. Starting a small business also teaches skills that traditional classes rarely offer, such as ②managing money, marketing a product, and handling customer complaints. However, young entrepreneurs face real ③challenges too. Many lack enough money or experience to make their business grow quickly, and mistakes can feel ④encouraging at first. Still, most teen entrepreneurs say that failure taught them more than any success did, and schools now offer entrepreneurship clubs to support these ⑤beginners.

Storing summer fruit properly can help you avoid waste and enjoy fresher flavors. (A) Berries, however, should not be washed until just before eating, because moisture encourages mold to grow. (B) Watermelon and melon should be kept in the refrigerator once they are cut, since warm air speeds up spoiling. (C) Bananas, unlike most fruit, are best kept on the counter rather than in the refrigerator.

The discovery of CRISPR gene-editing technology gave scientists a tool precise enough to correct a single mistaken letter in the human genome, raising hope for curing inherited diseases. (A) Scientific organizations around the world have therefore drawn a careful line, permitting gene editing to treat disease in existing patients while banning any edit that would be inherited by their descendants. (B) Yet editing a gene in a sperm, egg, or early embryo does not simply change one patient; it alters the genetic code passed down to every future generation. (C) Critics worry, however, that as the technology becomes cheaper and more widely available, this line will become harder to enforce than it is to draw.

Learners can pause a lecture, rewind it, and watch it again until the concept becomes clear. Online courses have become a popular way for students to learn practical job skills outside of school. ( ① ) Platforms now offer classes on coding, video editing, graphic design, and even small business management. ( ② ) Unlike traditional classes, these courses let learners study at their own pace and repeat difficult lessons as many times as needed. ( ③ ) Many courses also include practical projects, so students can build a portfolio while they learn. ( ④ ) However, taking an online course requires strong self-discipline, since no teacher checks whether students are keeping up. ( ⑤ ) Experts recommend setting a fixed weekly schedule and finishing small assignments regularly.
