Attention, students and teachers! Our school is starting a new campaign called 'Bring Your Own Bag.' Starting next Monday, the school store will no longer offer free plastic bags to customers. Instead, we encourage everyone to bring a reusable shopping bag from home. Plastic bags, ①which are made from petroleum, take hundreds of years to break down in the environment. In contrast, a cloth bag can be ②used again and again for many years. Therefore, ③using a reusable bag is a simple habit that protects sea animals and reduces pollution. For example, students ④who bring their own bags will receive a small sticker as a reward. However, students who forget their bags may still ⑤purchases a paper bag for a small fee. We hope every student will join this easy and meaningful campaign. Thank you for helping our school become greener.

Every plastic product carries a small recycling mark, but few students know ①what these marks mean. Each symbol contains a number ②that shows what material the item is made of. Reading these marks is similar to ③reading nutrition labels on snacks, which tell you exactly what is inside. Likewise, ④throwing 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 ⑤sorted separately.

Many people throw away items that they no longer need. However, some students have started to buy and sell used goods instead of throwing them away. This practice, often called secondhand trading, takes place at flea markets or through simple online apps. When you buy a secondhand book or a used bicycle, you ①save money and reduce waste at the same time. For example, a jacket that no longer fits your older sibling can become a treasure for someone else. Giving an old item to a new owner is like giving a toy a second life. In contrast, throwing away useful items ②decreases the amount of trash that ends up in landfills. Therefore, secondhand trading, which requires ③little effort, protects both your ④wallet and the environment. Small choices like this can make a ⑤big difference for our planet.

When you separate paper, plastic, glass, and cans, recycling centers can process each material more ①efficiently. For example, plastic bottles should be rinsed and have their caps removed before being thrown away. Paper soaked with food or oil, however, cannot be recycled and must go into general waste. If items are mixed together ②carefully, finding what you need later becomes difficult. Likewise, mixing recyclables with ordinary trash makes the whole recycling process ③complicated. Many students believe that sorting trash takes too much time, but it actually requires only a few extra ④seconds. Therefore, learning these basic rules now helps you build a habit that ⑤benefits your entire community.

When Minji was in ninth grade, she posted a joking comment mocking a classmate's photo, never imagining anyone would remember it later. Last spring, she applied to join her school's student council, hoping her leadership experience would impress the selection committee. During the interview, however, one teacher mentioned having seen an old, unkind comment under Minji's name while reviewing applicants' profiles. Startled, Minji realized that everything she had ever posted online had quietly accumulated into what is called a digital footprint, a lasting trail of personal data left behind by online activity. Although she deleted the comment immediately, the damage to her reputation had already been done. She understood that digital footprints ___________.

Yuna bought a disposable coffee cup every morning on her way to school. She never thought about where those cups ended up after she threw them away. One day, her science teacher showed the class a photo of a beach covered with plastic cups and bottles. Yuna felt shocked because she realized _______________. That evening, she found an old tumbler hidden in a kitchen drawer and decided to use it every day. At first, carrying the tumbler felt inconvenient, and she often forgot to bring it to school. However, she kept a reminder note on her bag, which helped her remember it each morning. Within a month, using the tumbler had become as natural as brushing her teeth. Her friends noticed the change and asked where she had bought the tumbler.

Minjun used to leave half of his lunch tray full of untouched rice and vegetables every day. (A) However, his teacher explained that leftover food thrown away every day adds up to a huge amount of waste. She compared uneaten food to money dropped carelessly on the street, which nobody bothers to pick up. (B) Last spring, his class started a campaign called "Clean Plate Day" to reduce food waste, but at first, Minjun thought it sounded boring and unnecessary for someone like him. (C) This comparison surprised Minjun because he had never thought about food that way before. He decided to take only what he could finish and to try new vegetables slowly. Within a few weeks, his tray was almost always empty, and he felt proud of the change. Other students noticed his effort and began doing the same thing.

Many people who try digital detox for the first time report feeling anxious within the first few hours. (A) This initial discomfort, sometimes called withdrawal anxiety, tends to fade after a day or two as the mind adjusts to reduced stimulation. (B) Once that adjustment period passes, most participants describe a noticeable sense of calm that they had not expected. (C) This unexpected calm often motivates people to repeat the practice regularly instead of treating it as a one-time experiment.

주어진 문장: Yet this same tendency also carries a hidden drawback. Sociologists use the term homophily to describe the tendency of people to form connections with others who share similar backgrounds, opinions, or interests. ( ① ) This principle explains why classmates from the same major often become close friends, while coworkers with shared hobbies naturally gravitate toward one another. ( ② ) Because similarity reduces the effort required to understand another person's perspective, relationships built on shared traits tend to feel comfortable and require less negotiation. ( ③ ) However, this same comfort can narrow the range of viewpoints someone encounters, since surrounding oneself with similar people limits exposure to different ideas. ( ④ ) Social media platforms intensify this pattern through recommendation algorithms that suggest new friends based on shared interests or similar browsing history. ( ⑤ ) As a result, users often find their online circles becoming increasingly homogeneous, filled with people who think and behave much like themselves.

주어진 문장: Because the number of likes a post will receive is never guaranteed, every notification carries a small element of suspense. Psychologists have long studied a mechanism called the variable reward schedule, in which rewards arrive unpredictably rather than after every single action. ( ① ) Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. ( ② ) When someone posts a photo, they cannot predict exactly when likes will appear, nor how many they will eventually receive. ( ③ ) This uncertainty triggers a small burst of dopamine each time the phone is checked, regardless of whether the result is disappointing or thrilling. ( ④ ) Consequently, users often refresh their feeds compulsively, hoping the next check will finally bring a satisfying reward. ( ⑤ ) 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 consciously recognize this hidden mechanism and set firm limits on their checking habits.
