Smartphones, tablets, and computer screens all emit a significant amount of blue light, a short-wavelength light that our eyes are especially ①sensitive to. During the day, exposure to blue light from the sun helps keep us alert and mentally sharp, which is generally beneficial. At night, however, the same wavelength can interfere with the body's natural preparation for sleep. Specialized cells in the retina ②detect blue light and send signals to the brain's internal clock, ③suppressing the release of melatonin, the hormone that signals it is time to rest. Studies have found that ④people who scroll through their phones in bed before sleeping take longer to fall asleep and experience lighter, more easily disrupted sleep than those who avoid screens. Some devices now offer a night mode that shifts the display toward warmer tones, reducing blue light output in the evening. While this feature may help slightly, sleep researchers generally recommend ⑤limit screen use altogether in the hour before bedtime for the best results.

Psychologist Leon Festinger introduced social comparison theory, which ①explains that people evaluate their own abilities and opinions by comparing themselves with others. According to this theory, individuals engage in upward comparison when they measure themselves against someone ②who appears more successful, attractive, or accomplished. Social media platforms, filled with carefully edited photos and exaggerated achievements, ③provide endless opportunities for this kind of comparison. For instance, a teenager browsing vacation pictures posted by classmates may begin to feel that her own ordinary life ④are somehow inadequate. Unlike comparing oneself with someone in a similar position, which can sometimes boost confidence, upward comparison frequently ⑤triggers envy, dissatisfaction, and lower self-esteem.

The Hopeful Start Workshop will be held on January 10th at the Green Hill Community Center. This event ①helps students set clear and realistic goals for the new year. Participants will learn simple methods for ②writing goals that are specific and easy to measure. Each participant will receive a goal-planning notebook ③to use throughout the year. The workshop is open to all middle and high school students, and no experience ④are required. Students can register online through the center's website or by ⑤calling the front desk before January 8th.

On the first day of winter break, my friend Yuna and I sat in a cafe and talked about the new year ahead. Instead of ①making separate plans, we decided to write our goals together on one sheet of paper. Yuna wanted ②improving her English speaking, while I wanted to wake up earlier every morning. We agreed ③to text each other every night to report what we had done that day. Yuna, ④who noticed my short replies, called me instead of just texting. Because we supported each other through difficult moments, both of us ⑤successfully reached our goals by spring.

Psychologists have long studied a mechanism called the variable reward schedule, in which rewards arrive ①predictably rather than after every single action. Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. When someone posts a photo, they cannot predict exactly when likes will appear, nor how many they will eventually receive. This uncertainty triggers a small burst of dopamine each time the phone is checked, regardless of whether the result is ②disappointing or thrilling. Consequently, users often refresh their feeds ③compulsively, hoping the next check will finally bring a satisfying reward. What makes this troubling is that technology companies ④deliberately designed notification systems using insights borrowed from gambling research, rather than stumbling upon them by accident. Such practices raise serious ethical questions about ⑤manipulating users' brains for profit.

Attention, students! Our school festival is going green this year, and we truly need your help. This event aims to ①reduce the disposable waste that usually piles up during the celebration. First, please bring your own cup, plate, and utensils to every food booth you visit. Second, each booth should use ②reusable decorations rather than paper banners that get thrown away within hours. Students who join as Green Helpers will manage the recycling stations, sorting cans, bottles, and paper ③carefully all day long. Therefore, everyone's small cooperation will directly ④increase the amount of trash sent to the landfill. However, single-use plastic bags are ⑤strictly prohibited at every booth this year.

For most of last year, Junho refreshed his social media feed constantly, ①terrified of missing a party, a trending meme, or gossip among his friends. This restless anxiety, often called FOMO, or the fear of missing out, left him ②relaxed and strangely unsatisfied even after hours of scrolling. One weekend, his phone battery died during a hiking trip, and, to his surprise, he actually ③enjoyed the quiet afternoon without notifications interrupting his thoughts. Curious about this ④unexpected calm, Junho began deleting social apps for a few hours each day. This shift in attitude reflects what psychologists now call JOMO, a mindset that treats disconnection as ⑤freedom rather than loss.

Have you ever noticed that an unfinished task keeps returning to your mind long after you stopped working? This phenomenon was first noticed by psychologist Bluma Zeigarnik, who saw that waiters remembered unpaid orders better than paid ones. Her observation led to what is now called the Zeigarnik effect: ___________. According to this theory, the mind maintains mental tension until a task reaches closure, keeping the unfinished task active in memory.

Job seekers often assume that their closest friends will be the most helpful source of career advice. (A) In fact, studies show that a surprising number of job offers come through acquaintances met only briefly at conferences or previous workplaces. (B) However, close friends usually work in the same field or social circle, so their knowledge of new openings tends to overlap with what the job seeker already knows. (C) This is because such acquaintances belong to different professional circles, giving them access to information that never reaches close friends.

Emotions can spread from one person to another without a single word being spoken face to face. (A) For example, a cheerful comment posted early in a thread often encourages later commenters to write in a similarly positive tone. (B) Recently, however, psychologists have found that this same spreading effect happens even online, through text and images alone. (C) This means that a single post can shape the emotional tone of an entire online conversation.
