영어 모의고사 (자동 편성)

A growing number of teenagers are ① joining book clubs that exist only on their phones. These apps let users ② tracking how many pages they read each day, write short reviews, and join group chats about a chosen book. Some students say the apps make reading feel less lonely, because they can share their honest reactions the moment they ③ finish a chapter instead of waiting for a weekly meeting. The apps also use gentle reminders and reading streaks to keep members motivated, ④ turning a private habit into a small social game. However, a few teachers worry that constant notifications from a reading app can ⑤ pull attention away from the book itself, since users may spend more time chatting about the story than actually reading it.

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.

Last spring, Mina joined the school environmental club because she wanted to make a difference. At first, she felt ①nervous about speaking in front of the other members. However, the club leader, who had been recycling for years, welcomed her ②warmly. Every Friday, the members walked around the school picking up trash near the playground. Mina soon realized that this weekly habit was like watering a small plant every day. For example, a single plastic bottle left outside could take hundreds of years to ③disappear. Therefore, the club decided to place clear recycling bins in every classroom. In contrast to her early doubts, Mina began to feel ④proud of the changes she noticed. Her classmates ⑤stopped separating cans and paper without being reminded by teachers. By the end of the semester, Mina had become an active member.

When temperatures drop below freezing overnight, an invisible layer of black ice can form on sidewalks that look perfectly dry, catching even careful walkers off guard. Unlike a visibly icy patch, black ice reflects almost no light and blends into ordinary pavement, which is why _______________. Orthopedic doctors report a sharp rise in wrist and hip injuries every winter, most of them caused not by dramatic slips on icy hills but by a single unexpected step near a bus stop or a doorway.

For many students, the walk to school feels so routine that safety becomes an afterthought, yet a surprising number of accidents occur within a few blocks of the school gate. Part of the danger comes from convenience: _______________. This shortcut becomes especially risky during the darker months, when a driver's ability to spot a pedestrian drops sharply well before sunrise or after sunset.

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.

Earthquakes strike without any warning, which is exactly why the seconds immediately after the shaking begins matter more than any other moment in an emergency. (A) Furniture that seems merely inconvenient during a fire drill, such as a heavy desk, becomes a lifesaving shield when the ceiling above begins to crack. (B) Safety experts consistently teach the same three steps: drop to the ground, take cover under sturdy furniture, and hold on until the shaking stops. (C) Many people instinctively want to run outside during a quake, imagining that open space is always safer than a building, but this instinct can be dangerous, since falling debris often causes more injuries near exits and windows.

Electric scooters have become a common sight on city sidewalks, offering a quick way to cover short distances, yet most riders climb on without ever putting on a helmet. (A) Part of the problem is that renting a scooter takes only a few taps on a phone screen, while finding and carrying a helmet requires planning that many riders simply skip. (B) Emergency room doctors note that scooter-related head injuries have risen sharply in recent years, closely tracking the rise in scooter popularity itself. (C) Unlike a bicycle, which typically requires balance skills built up over years of practice, an electric scooter can reach a surprising speed within seconds, often faster than new riders expect.

Watching him, it occurred to me that my comics might serve exactly the same quiet purpose. Whenever someone learns that I spend hours drawing comics that almost nobody else ever sees, they usually ask why I bother, since the work will never be published or praised by a large audience. ( ① ) For a long time, I struggled to answer that question honestly, assuming that art only counted as worthwhile once other people recognized it. ( ② ) Watching my younger brother build enormous, pointless block towers purely for the joy of knocking them down, though, helped me understand something I had been missing. ( ③ ) He never once asked whether his tower was good; he simply needed to build the version of it that existed in his head before he could feel satisfied. ( ④ ) Creating something, I now believe, often serves the creator first, giving shape to a feeling or idea that would otherwise stay vague and unexpressed. ( ⑤ ) Whether or not anyone else ever sees the result, that private act of shaping an idea into something real still seems to matter enormously.

This sudden and violent stop is precisely what causes so many of the most severe injuries in a crash. Seatbelts are so woven into the experience of riding in a car that many passengers buckle them without thinking, yet a surprising number of teenagers still skip them for short trips, assuming that a five-minute drive to a friend's house does not carry much risk. ( ① ) Traffic safety data tell a different story: most fatal crashes occur within a few kilometers of home, on roads drivers know so well that they let their guard down. ( ② ) In a collision, a body traveling at a moderate speed continues moving forward at that same speed until something stops it, and without a seatbelt, that something is often the windshield or the dashboard rather than a slower deceleration. ( ③ ) A seatbelt spreads the force of a sudden stop across the stronger parts of the body, such as the hips and chest, instead of concentrating it on the head and neck. ( ④ ) Despite decades of public awareness campaigns, seatbelt use for backseat passengers remains lower than for those sitting in the front. ( ⑤ )
