Long before humans learned to drill for oil, microorganisms had already mastered the art of ①converting sunlight and carbon dioxide into stored chemical energy. Modern biofuel research borrows this ability, cultivating algae or engineered bacteria in large tanks where they can be ②coaxed into producing oils and sugars that can be refined into fuel usable in existing engines. Unlike crops grown for corn-based ethanol, which compete directly with food production for arable land, many algae strains can ③thrive in shallow ponds, wastewater, or even coastal seawater unsuitable for conventional agriculture. Engineers have also learned to tinker with the metabolic pathways of these organisms, ④boosted oil yield far beyond what any wild strain would naturally produce on its own. Despite this progress, producing biofuel at a cost competitive with fossil fuel remains difficult, since harvesting and processing the organisms consumes a substantial share of the energy the fuel itself will eventually ⑤provide.

Jimin joined the school band club in March, but she ①had never performed before an audience. The club's first concert was only two weeks away, and everyone felt nervous. During practice, her hands shook whenever the song reached the chorus, and she kept missing the same chord. Instead of laughing at her mistakes, the other members waited patiently and ②playing the section again with her. The drummer, Suho, suggested that she ③focus on just one part at a time. Slowly, her fingers grew more confident, and the chord ④that once felt impossible began to feel natural. The club practiced until the melody sounded smooth the night before the concert. When Jimin walked onto the stage, she thought of her friends' patience instead of her fear. The audience clapped warmly, and she realized ⑤her club's support had made the difference.

Water looks ①limited when it flows from the tap every morning. However, clean water is actually a limited resource that we must protect carefully. Many families waste water without even noticing it in their daily routine. For example, leaving the tap running while brushing your teeth can waste several liters of water. In contrast, turning off the tap during that time ②saves a surprising amount of water each day. Taking a shorter shower is another easy habit that reduces water use ③significantly. Fixing a leaking faucet, which many people ignore, can also ④save hundreds of liters every month. Saving water is like keeping money in a savings account for the future. Therefore, small changes in our daily habits, practiced by every family, can protect this ⑤precious resource. Everyone who cares about the environment should start saving water today.

For a class project, I interviewed a local architect who has worked in the field for over fifteen years. She explained that architects must ①balance creativity with practical concerns like safety and cost. When I asked about challenges, she mentioned that clients sometimes change their minds after a design is finished. Instead of feeling frustrated, she said she tries to see each change as a ②chance to improve the project. She also advised students to visit construction sites whenever possible, since seeing a real building take shape teaches ③valuable lessons no classroom can offer. At the end of the interview, she smiled and said that choosing architecture was the ④worst decision she had ever made. Her passion made me ⑤consider design as a possible career for myself.

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.

Summer heat can be just as dangerous for pets as it is for people, because ___________. Owners must therefore provide plenty of fresh water, avoid walking pets during the hottest hours, and never leave them alone in a parked car.

Turning off lights when you leave a room seems like a tiny action, but _______________. Every light left 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 to charge dozens of phones. This habit is similar to leaving a faucet running while you brush your teeth, where water flows out for no reason. Both actions seem harmless in the moment, but they add up to a serious waste over time. Some students argue that a single light does not make much difference. However, when an entire school forms this habit together, the total amount of saved energy becomes significant. Therefore, this small daily habit can create a surprisingly large positive effect for the whole planet.

The subscription economy has changed the way many people think about ownership. (A) As a result, companies can predict their income more accurately and plan their operations accordingly. (B) Rather than buying products outright, consumers increasingly prefer paying small recurring fees for continued access. (C) This shift benefits businesses as well, since steady monthly payments create a stable source of revenue.

주어진 문장: This step matters because greasy or wet waste attracts insects during collection. Dear residents, we are writing to explain how to separate food waste correctly in our building. Many people still throw food waste into the general trash, which causes bad smells. ① Therefore, this notice describes the exact steps you should follow every day. First, please use the special yellow bin near the parking lot for all food scraps. ② Fruit peels, vegetable ends, and leftover rice belong in this bin, not in a plastic bag. However, hard items such as eggshells and bones must go into the general trash instead. ③ In addition, please drain excess liquid from your food waste before throwing it away. ④ This simple habit, which only takes a few seconds, keeps the area clean and dry. For example, tea bags should never be placed in the food waste bin. ⑤ Thank you for helping our neighborhood stay pleasant.

주어진 문장: This same routine has continued every week since the project began in March. The science club at Hanul High School is running a project called "Grow Light." It tests how different colors of light affect plant growth. ( ① ) Each week, members place identical bean sprouts under red, blue, and white light and record their height. ( ② ) At first, many students expected the white light to produce the tallest plants. ( ③ ) However, the results showed that plants under red light grew noticeably faster than the others. ( ④ ) The club's advisor explained this by comparing light to food. Just as people need certain nutrients to grow strong, plants absorb certain colors of light more efficiently than others. ( ⑤ ) To make the data reliable, students repeat each trial three times and calculate the average. They also keep a shared notebook, recording sunlight, watering time, and temperature. Next month, the club plans to present these findings at the school science fair.
