영어 모의고사 (자동 편성)

Every light ①left on in an empty room wastes electricity that could have powered something useful elsewhere. For example, a single classroom light left on overnight can waste enough energy ②to charge dozens of phones. This habit is similar to ③leave a faucet running while you brush your teeth, where water flows out for no reason. However, when an entire school ④forms this habit together, the total amount of ⑤saved energy becomes significant.

Many students take a career aptitude test at some point in high school. This test is ①designed to measure a person's interests, strengths, and personality traits. It does not simply tell students which job to choose; instead, it helps them ②understand themselves better. For example, a student who enjoys solving problems might discover a ③hidden interest in engineering. However, the results should be used only as a guide, not as a ④temporary answer. Therefore, students should treat the test as a useful starting point, rather than a fixed decision that ⑤limits their future choices.

At first, Minjun thought the campaign sounded ①boring and unnecessary for someone like him. However, his teacher explained that leftover food thrown away every day adds up to a ②huge amount of waste. This comparison ③surprised Minjun because he had never thought about food that way before. Within a few weeks, his tray was almost always ④full, and he felt ⑤proud of the change.

Our school's volunteer club, Helping Hands, tries to _______________. Each month, students visit a nearby nursing home and spend an afternoon talking with elderly residents. For example, they read newspapers aloud or just listen to old stories from the residents. In addition, members collect used books and toys from classmates and donate them to a community center downtown. Some students feel nervous before their first visit, unsure of what to say to strangers. However, most discover that a warm smile works better than perfect words. Therefore, the club's real goal is not just finishing hours for a report card. Instead, it teaches members that caring for others grows into a lasting habit, like watering a plant daily. By the end of the year, many students say the club changed how they see their community.

Every summer, doctors warn about the danger of heatstroke, a serious condition in which ___________. This condition can be life-threatening if it is not treated quickly. To prevent heatstroke, drink plenty of water throughout the day, avoid outdoor activities during the hottest hours, and wear light, loose clothing.

Every plastic product carries a small recycling mark, but few students know what these marks mean. Each symbol _______________. For instance, the number one usually stands for clear plastic bottles, while the number five represents thicker containers like yogurt cups. Reading these marks is similar to reading nutrition labels on snacks, which tell you exactly what is inside. Without checking the label, you might buy something unhealthy by mistake. Likewise, throwing plastic away without checking its mark can send a reusable item straight to a landfill. Some marks even show that a material cannot be recycled at all, so it must be sorted separately. Therefore, taking a few seconds to check the mark before throwing something away makes recycling far more effective for everyone involved.

Physical education class often feels like the one period of the day when students can finally move freely, which sometimes leads them to skip the warm-up routine that teachers insist on before any real activity begins. (A) Beyond warming up, wearing proper footwear matters more than most students realize; running in worn-out sneakers with little grip left on the sole significantly raises the chance of a twisted ankle. (B) Coaches often compare an unwarmed muscle to a cold rubber band that snaps rather than stretches under sudden pressure. (C) Cold muscles, however, are noticeably less flexible than warmed ones, and stretching a stiff hamstring or ankle too quickly can cause a strain that keeps a student off the field for weeks.

Many English teachers now ask students to write a short review after finishing a book, rather than simply filling out a reading log. (A) Teachers who assign reviews regularly report that their students remember plot details more accurately and discuss characters' motivations more confidently than students who only summarize. In this sense, writing a review is not extra work added onto reading; it is a way of reading more carefully in the first place. (B) To defend an opinion about a character or a theme, students must return to the book and find exact passages that support their view. This process forces readers to notice details they might have skipped during a first, quick reading. (C) At first, students often complain that summarizing a plot is enough work already, so writing an opinion on top of that feels unnecessary. However, a review requires something a summary does not: a clear judgment supported by specific evidence from the text.

Artificial intelligence is creating job titles that did not exist a decade ago. (A) AI ethics officers, for instance, check whether a company's technology treats users fairly. (B) These new roles clearly require more than just technical skill. (C) Prompt engineers, for example, design instructions that help AI programs produce accurate results.

This is because thirst is often a sign that your body is already dehydrated. Drinking enough water is especially important during the hot summer months, and experts recommend drinking regularly rather than waiting until you feel thirsty. ( ① ) When you sweat a lot, your body loses not only water but also important minerals called electrolytes. ( ② ) If you do not replace these losses, you may feel tired, dizzy, or even suffer from muscle cramps. ( ③ ) It is best to avoid sugary drinks and too much caffeine, since they can make dehydration worse. ( ④ ) Instead, choose plain water or drinks that contain electrolytes, especially after exercise. ( ⑤ ) Eating water-rich fruits and vegetables can also help you stay hydrated.
