It can bring us happiness, but sometimes it can also cause trouble. I had a funny experience last month that I will never forget. I went to the supermarket to buy some groceries. Before leaving home, my wife told me to buy a bottle of cooking oil and a loaf of bread. I repeated the items to myself several times to ___16___ them in mind. “Oil and bread, oil and bread,” I whispered. When I arrived at the supermarket, it was very crowded. I took a basket and walked around. I saw the milk section and thought, “Should I buy milk?” Then I saw the fruit and thought about apples. I was so ___17___ by all the choices that I forgot my original list. Suddenly, I had a flash of memory. “I need to buy oil!” I said to myself. So I found the cooking oil and put it in my basket. But what was the other thing? I stood in the middle of the aisle, trying hard to ___18___ it. Was it rice? Was it sugar? I just couldn't ___19___ what it was. Just then, my phone rang. It was my wife. “Have you bought the oil and the bread?” she asked. “I have the oil,” I replied, “but I’ve ___20___ what the other thing is.” She laughed and said, “It’s bread! You remembered it when you left home, but now you’ve ___21___ it.” I felt a bit embarrassed, but I laughed too. I went to the bakery section and picked up the bread. On my way home, I thought about how our memory works. We remember things we ___22___ on, but we can easily forget things if we don't pay enough attention. This experience taught me a lesson. Now, I always write down important things on a ___23___ or set a reminder on my phone. It helps me avoid ___24___ things up and saves me from trouble.

You are not alone. Many students struggle with memory. Here are some tips from memory experts to help you improve: Tip 1: The Power of Repetition Don’t just read your notes once. Repeat the information several times. Read it aloud, write it down, and then explain it to someone else. This strengthens the connections in your brain. Tip 2: Create a “Memory Palace” This ancient technique involves imagining a familiar place, like your house. Then, you place the items you want to remember in different rooms. When you need to recall them, mentally walk through your house and “see” the items. Tip 3: Use Chunking Break down large amounts of information into smaller, manageable “chunks.” For example, instead of trying to remember a 10-digit phone number as single digits, group them into chunks (e.g., 123-456-7890). Tip 4: Get Enough Sleep Sleep is crucial for memory consolidation. When you sleep, your brain processes and stores the information you learned during the day. Pulling an all-nighter before an exam can actually harm your memory. Tip 5: Stay Active and Eat Well Regular exercise increases blood flow to the brain, which helps memory. Foods rich in omega-3 fatty acids, like fish, are also known to boost brain health. 26. What is the main purpose of Tip 2? A. To explain how to use a real palace for study. B. To suggest a method for organizing physical spaces. C. To introduce a technique for remembering items by visualization. D. To encourage students to walk more in their houses. 27. According to the passage, why is sleep important for memory? A. It helps us stay awake during exams. B. It allows the brain to process and store information. C. It increases our blood pressure. D. It prevents us from eating too much. 28. Which tip suggests breaking information into smaller parts? A. Tip 1 B. Tip 2 C. Tip 3 D. Tip 4 29. Where is this passage most likely from? A. A science fiction novel. B. A student study guide. C. A cookbook. D. A travel brochure. B The Forgetting Curve Have you ever studied hard for a test, only to forget most of the information a week later? This phenomenon is described by the "Forgetting Curve," a theory proposed by German psychologist Hermann Ebbinghaus in 1885. Ebbinghaus conducted experiments on himself using nonsense syllables (like "ZOC" or "QAX"). He would memorize lists of these syllables and then test how much he remembered after different time intervals. He discovered that forgetting happens quickly at first. Without any review, a person might forget over 50% of newly learned information within an hour, and up to 70% within 24 hours. However, the rate of forgetting slows down over time. The good news is that Ebbinghaus also found that review can significantly flatten the curve. If you review the material shortly after learning it—say, within 20 minutes, then again after a day, and then after a week—you can retain much more information. This is known as "spaced repetition." Modern learning apps often use this principle. They schedule reviews at increasing intervals to help users move information from their short-term memory to their long-term memory. Understanding the Forgetting Curve can help students study smarter, not harder. Instead of cramming (突击学习) all at once, spacing out study sessions and reviewing regularly leads to better long-term retention. So, the next time you learn something new, don't wait until the night before the test to review. Start early, review often, and beat the Forgetting Curve! 30. Who proposed the "Forgetting Curve" theory? A. A modern app developer. B. A German psychologist. C. A science fiction writer. D. A high school teacher. 31. According to Ebbinghaus's experiment, how much information might a person forget within 24 hours without review? A. About 20%. B. About 50%. C. Up to 70%. D. Almost 100%. 32. What is "spaced repetition"? A. Reviewing material many times in one sitting. B. Cramming all information the night before a test. C. Reviewing material at increasing intervals over time. D. Forgetting information quickly and then relearning it. 33. What is the main message of the passage? A. Forgetfulness is a sign of a bad student. B. Cramming is the most effective way to study. C. Regular review helps combat the Forgetting Curve. D. The Forgetting Curve only applies to nonsense syllables. C Memory Athletes When you think of athletes, you probably picture runners, swimmers, or basketball players. But there is another type of athlete: the memory athlete. These individuals compete in memory championships, performing incredible feats like memorizing the order of a shuffled deck of cards in under 20 seconds, or recalling thousands of random digits. How do they do it? Do they have "photographic memories"? Most memory champions say they don't. Instead, they use a variety of mnemonic devices (记忆术)—techniques that help improve memory. One popular technique is the "Method of Loci," which is similar to the "Memory Palace" mentioned earlier. They also use associations, linking new information to familiar things, and chunking. Interestingly, research shows that memory athletes are not born with extraordinary brains. Their brains are structurally similar to those of average people. The difference lies in their intensive training and the strategies they employ. Anyone can learn these techniques and improve their memory significantly. However, memory athletes also caution that these techniques require a lot of practice and mental effort. They are tools, not magic. And while they are great for competitions, the most important thing for everyday life is to stay curious and engaged. A healthy lifestyle, including good sleep, exercise, and a balanced diet, remains the foundation for a good memory. So, while you might not aim to become a memory champion, exploring some of their techniques could help you ace your next exam or simply remember where you left your keys! 34. What is a common misunderstanding about memory athletes? A. They are very physically fit. B. They have photographic memories. C. They train very hard. D. They use mnemonic devices. 35. According to the passage, what is the "Method of Loci"? A. A way to shuffle cards quickly. B. A technique similar to the "Memory Palace." C. A method for recalling random digits. D. A type of physical exercise for the brain. 36. What does research suggest about the brains of memory athletes? A. They are completely different from average brains. B. They are structurally similar to average brains. C. They are born with special memory centers. D. They shrink after intense training. 37. What is the author's attitude towards using memory techniques in daily life? A. Strongly against it. B. Neutral, neither supporting nor opposing. C. Supportive, but emphasizes the importance of a healthy lifestyle. D. Believes they are only useful for competitions. D The Impact of Technology on Memory In the digital age, we have unprecedented access to information. With a few taps on our smartphones, we can find the answer to almost any question. But this convenience comes at a cost: some researchers argue that our reliance on technology is affecting our ability to remember. This phenomenon is sometimes called the "Google effect." Studies have shown that when people know they can easily look up information later, they are less likely to make an effort to remember it. Instead, they tend to remember where to find the information (e.g., which website or folder) rather than the information itself. This is known as "transactive memory"—relying on external sources as extensions of our own memory. While some worry that this makes us "lazy thinkers," others argue it's a natural adaptation. Just as we don't need to remember phone numbers anymore because we have contacts lists, we don't need to remember every fact because we have the internet. This frees up our brains to focus on more complex tasks, like critical thinking and creativity. However, there are downsides. Over-reliance on GPS, for example, can weaken our spatial memory—our ability to navigate without assistance. Constant notifications from our devices can also fragment our attention, making it harder to form solid memories in the first place. The key is balance. Technology can be a powerful tool to augment our memory, but it shouldn't replace the cognitive effort needed to encode and retrieve information. We should use technology wisely, leveraging it to store information while still exercising our own memory muscles through learning and practice. 38. What is the "Google effect"? A. The tendency to use Google for everything. B. The impact of Google on the stock market. C. The reduced effort to remember information that can be easily looked up. D. The improvement in memory due to using search engines. 39. What is "transactive memory" as described in the passage? A. Sharing memories with other people. B. Relying on external sources as extensions of our own memory. C. A type of memory loss caused by technology. D. A new feature in Google's search engine. 40. According to the passage, what is a potential downside of over-reliance on GPS? A. It can drain the car's battery quickly. B. It can weaken our spatial memory. C. It can make us too dependent on satellites. D. It can cause us to get lost more often. 四、根据句意及中文提示写出单词，使句子完整正确。(本大题共10小题，每小题1分，共10分) 根据中文提示或首字母提示，填写正确的单词，每空一词。 41.

For example, you might review new vocabulary 53 _______(short) after learning it, then again a day later, and then a week later. This helps move information from your short-term memory to your long-term memory. Another tip is to use mnemonics. These are memory aids 54_______ help you associate new information with something you already know. For instance, to remember a shopping list, you might create a funny story 55 _______(connect) all the items. Also, getting enough sleep is vital because it is during sleep 56_______ your brain consolidates memories. Avoid cramming, as it is 57_______ (effective) than regular review. Instead, try to study a little every day. Your brain will thank you for it! B I used to have a poor memory. I 58_______ (constant) forgot where I put my keys or what my homework was. It was frustrating. Then, my teacher introduced me to some memory techniques. She suggested 59_______ (write) down important things in a notebook. She also taught us how to use the "Memory Palace" technique. At first, it seemed difficult, but I practiced every day. Now, I can remember much 60_______ (much) than before. I even won second place in a school memory contest! I've learned that with the right strategies and consistent effort, anyone can sharpen their memory. 六、任务型阅读（共5小题，每小题2分，满分10分） 阅读下面短文，根据要求完成各小题。 How to Improve Your Memory Naturally Many people worry about their memory as they age, but memory decline is not inevitable. There are several natural ways to boost your brainpower and keep your memory sharp. First, stay physically active. Exercise increases blood flow to the whole body, including the brain. This can help keep your memory sharp. Aim for at least 150 minutes of moderate aerobic activity, like brisk walking, every week. Second, eat a brain-healthy diet. This includes fruits, vegetables, whole grains, and lean proteins. Foods rich in omega-3 fatty acids, such as salmon and walnuts, are particularly good for brain health. Limit sugar and saturated fats. Third, get enough quality sleep. Sleep plays a crucial role in memory consolidation. Most adults need 7-9 hours of sleep per night. Try to maintain a regular sleep schedule. Fourth, manage stress. Chronic stress can damage brain cells and affect memory. Practice relaxation techniques like meditation or deep breathing. Finally, stay socially and mentally active. Engage in activities that challenge your brain, such as puzzles, learning a new skill, or reading. Social interaction also helps ward off depression and stress, which can contribute to memory loss. By incorporating these habits into your daily routine, you can support your memory and overall brain health. 注：每题答案不超过5个词。 61. How much moderate aerobic activity is recommended weekly? 62. What kind of foods are particularly good for brain health? (Name one) 63. How many hours of sleep do most adults need per night? 64.

It helps us absorb knowledge quickly and improves our study efficiency. With a sharp memory, we can easily recall key points in exams and connect new information with what we've already learned, making learning less stressful and more enjoyable. To enhance our memory, several effective methods are worth trying. First, regular review is crucial. As the saying goes, "Practice makes perfect." Reviewing notes shortly after learning and then at intervals helps transfer information to long-term memory. Second, maintaining a healthy lifestyle is essential. Getting enough sleep, eating brain-boosting foods like fish and nuts, and doing regular exercise can significantly improve our brainpower. In my view, a good memory is not just a gift but a skill that can be developed. By adopting these habits, we can all sharpen our memory and achieve better academic results.
