An echo chamber refers to an online environment where people are mainly ①exposed to opinions that already match their own beliefs. This phenomenon occurs because social media algorithms tend to ②recommending content similar to what users have previously liked or shared, gradually narrowing the range of perspectives they encounter. As a result, individuals inside an echo chamber rarely engage with viewpoints ③that challenge their existing assumptions, which allows their original beliefs to grow increasingly extreme over time. For example, someone who frequently reads articles supporting one political party may begin to see the opposing party as entirely unreasonable, ④having never seriously considered its arguments. Political polarization, a significant issue in many countries today, is often ⑤linked to this pattern of selective exposure.

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.

Many people throw away items ①that they no longer need. However, some students have started ②to buy and sell used goods instead of throwing them away. This practice, often ③called secondhand trading, takes place at flea markets or through simple online apps. When you buy a secondhand book or a used bicycle, you save money and reduce waste at the same time. For example, a jacket that no longer ④fit 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 increases the amount of trash that ends up in landfills. Therefore, secondhand trading, ⑤which requires little effort, protects both your wallet and the environment. Small choices like this can make a big difference for our planet.

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

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.

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.

Every day, we leave behind marks of the gases that warm our planet, much like footprints ①left in wet sand. These marks, often called our carbon footprint, come from small choices such as driving, eating, and using electricity. Many students think that only ②small factories create these marks, but ordinary habits at home also matter greatly. For example, turning off lights when leaving a room ③reduces the energy that power plants must produce. Walking or biking to school instead of riding in a car also ④lowers the amount of gas released into the air. In contrast, leaving devices plugged in all night quietly increases our footprint without our notice. Therefore, students who practice these simple habits regularly can ⑤shrink their footprint significantly.

Before a single line of dialogue is written for many animated shows, a character designer has already spent weeks deciding how that character should look, move, and be recognized at a glance. A visiting illustrator who spoke at our school explained that a truly successful design should be identifiable even as a plain black silhouette, since audiences often notice a character's outline before they notice any facial detail. She showed us early sketches of a now-famous cartoon hero, in which the same personality had been tested through dozens of different body shapes, from short and round to tall and angular, before the final version was chosen. Small choices, she added, carry surprising weight: rounded shapes tend to feel friendly and safe, while sharp angles suggest danger or power, even to viewers who have never studied design. I left the talk realizing that _______________.

Last Saturday, Jimin visited the recycling center near her apartment with her science class. She had expected the place to be dirty and unpleasant, but _______________. A worker named Mr. Park guided the students through each area, explaining how bottles, cans, and paper were sorted. He showed them a machine that crushed plastic bottles into small pieces before they were sent to factories. Jimin was surprised to learn that mixed trash, thrown into the wrong bin, often ruined an entire batch of recyclables. For example, one greasy pizza box could contaminate a whole pile of clean paper. However, when items were sorted correctly, they could be reused many times, almost like ingredients in a favorite recipe. Walking home, Jimin realized that her small effort at home truly mattered. She decided to sort her family's trash more carefully.

주어진 문장: This is why many coaches encourage athletes to keep their pre-game rituals exactly the same, even when circumstances change. Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. ( ① ) This theory explains that every habit begins with a cue, a signal that tells the brain to start an automatic behavior. ( ② ) The brain then performs a routine, which is the action itself, whether physical or mental. ( ③ ) Finally, the brain receives a reward, a positive feeling that makes it want to repeat the same behavior. ( ④ ) For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run without conscious thought. Because this loop operates automatically, breaking a bad habit requires changing the routine while keeping the same cue and reward. ( ⑤ ) Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.
