Most people do. Memories like these are stored in our long-term memory. But how does our brain decide what to keep and what to throw away? Scientists say that emotions（情感）play a big role. We are more likely to remember things that made us feel very happy, very scared, or very __12__. For example, you probably remember your first day at school clearly because you felt nervous and excited. On the other hand, you might __13__ what you ate for lunch last Tuesday because it wasn’t very special. Another factor is repetition（重复）. If you hear a piece of information once, it might stay in your short-term memory for a few seconds. But if you review it again and again, it moves into your long-term memory. That’s why __14__ the same vocabulary words every day helps you remember them for a test. Sleep is also important for memory. While we sleep, our brain __15__ the day’s events and decides what to keep. Studies show that students who get enough sleep before an exam often get __16__ grades than those who stay up late studying. Their brains have had time to “save” the information properly. Interestingly, our senses can trigger（触发）memories. A certain smell, like freshly baked bread, might suddenly remind you of your grandmother’s kitchen. This is because the parts of the brain that handle smell and memory are closely __17__. However, memory isn’t perfect. Sometimes we remember things that didn’t actually happen, or we mix up details. This is called a false memory. For example, if someone tells you a story about your childhood often enough, you might start to “remember” it, even if you weren’t really there. Understanding how memory works can help us improve it. By staying organized, getting enough rest, and connecting new information to things we already know, we can make our memories __18__ and more reliable. After all, our memories make us who we are—they are our personal history books. 12. A. bored B. angry C. interested D. surprised 13. A. forget B. remember C. enjoy D. mind 14. A. looking up B. making up C. going over D. taking over 15. A. processes B. collects C. changes D. ignores 16. A. lower B. higher C. worse D. fewer 17. A. compared B. connected C. covered D. competed 18. A. shorter B. weaker C. stranger D. stronger Ⅳ. 阅读理解 「2026 重庆巴蜀中学月考改编」 Have you ever walked into a room and forgotten why you went there? Or struggled to remember a familiar name during a conversation? These moments are annoying, but scientists say they are completely normal—even for people with excellent memories. Researchers at the University of Toronto call this “event boundary effect”. An “event boundary” is when one activity ends and another begins. For example, walking through a doorway from the kitchen to the living room creates an event boundary. Your brain treats the living room as a new “event”, so it often “clears its desk” and stops thinking about why you were in the kitchen. This is why you suddenly forget your purpose. A 2011 study by Dr. Gabriel Radvansky tested this idea. He asked participants to memorize an object, then walk across a room and place it in a box. Some participants walked through a doorway to reach the box, while others walked the same distance within the same large room. The results showed that those who walked through the doorway were 15% more likely to forget what they were carrying. Why does this happen? Dr. Radvansky explains that our brain uses event boundaries to organize information efficiently. If our brain tried to remember every detail of every moment, it would be overwhelmed. By “resetting” at boundaries, it can focus on new information. However, this efficiency sometimes causes us to forget simple tasks. The good news is that there are ways to fight this. One simple trick is to pause for a second before crossing a boundary. Ask yourself, “What am I going to do next?” Saying it out loud can also help. Another method is to create a visual link—for example, if you’re going to the bedroom to get socks, imagine a giant sock on the bed as you walk through the door. So, next time you walk into a room and forget why, don’t worry. It’s not a sign of a bad memory—it’s just your brain doing its job a little too well. 19. The writer begins the passage by ______. A. telling a joke B. giving examples C. asking questions D. showing numbers 20. What is “event boundary effect”? A. The habit of forgetting names in conversations. B. The brain’s reset when moving to a new activity. C. The feeling of annoyance during a busy day. D. The difficulty in memorizing objects in boxes. 21. The underlined word “overwhelmed” in Paragraph 4 probably means “______”. A. 放松的 B. 困惑的 C. 不堪重负的 D. 充满希望的 22. What did Dr. Radvansky’s 2011 study find? A. Walking through doorways improves memory. B. People in large rooms forget things more easily. C. Doorways make people 15% more likely to forget. D. Participants forgot objects more often in the kitchen. 23. What is the best title for the passage? A. How to Improve Your Short-Term Memory B. Why Walking Through Doorways Makes You Forget C. The Importance of Event Boundaries in Daily Life D. Dr. Radvansky’s Study on Brain Efficiency Ⅴ. 阅读表达 「2026 河北石家庄43中期末改编」 阅读下面短文，根据短文内容回答问题。 Last month, 14-year-old Li Ming shared a photo on social media that touched many hearts. In the photo, he was holding a handmade notebook covered with blue cloth. The notebook had a carefully drawn logo of his favorite basketball team on the cover. Li’s family isn’t rich. His father is a construction worker, and his mother sells vegetables in the market. For his birthday, Li hoped to get a branded notebook like his classmates had, but it cost 80 yuan—too expensive for his family. Seeing this, his mother decided to make one herself instead of buying it. She spent three evenings cutting cloth, gluing pages, and drawing the logo. To make it more stylish, she also added a red ribbon bookmark and stitched Li’s initials “LM” on the corner. When Li received it, he was so moved that he posted the photo online with the words: “This is better than any store-bought gift.” The post quickly went viral, receiving over 50,000 likes and thousands of comments. One user wrote, “The love sewn into this notebook is priceless.” Li said he now uses the notebook to write down his daily goals and memories. “Every time I open it, I remember my mom’s hard work,” he said. “It teaches me that the most valuable things aren’t bought with money.” 24. Why didn’t Li Ming’s parents buy him the branded notebook? 25. Besides the logo, what did Li’s mother add to the notebook to make it stylish? 26.
