Without it, we could not learn, recognize our loved ones, or even find our way home. Scientists have divided memory into three main types: sensory memory, short-term memory, and long-term memory. Sensory memory is the briefest form of memory. It lasts for only a few seconds and holds information from our senses, such as what we see or hear. For example, when you look at a bright light and then close your eyes, the image you still see is your sensory memory at work. Short-term memory, also called working memory, holds information for about 15 to 30 seconds. It is the memory you use when you try to remember a phone number long enough to dial it. However, short-term memory has a limited capacity. Most people can hold only about seven items at a time. Long-term memory is the memory that lasts for days, years, or even a lifetime. Unlike short-term memory, it has a seemingly unlimited capacity. Information enters long-term memory through a process called consolidation, which often happens during sleep. That is why getting enough rest is so important for learning. Scientists have also discovered that memory is not stored in one single place in the brain. Instead, different parts of the brain work together to store different types of information. For example, the hippocampus is especially important for forming new memories, while the cerebellum helps with memories related to physical skills, such as riding a bike. Understanding how memory works can help us find better ways to learn and remember. As scientists continue to study the brain, they hope to unlock even more secrets of this amazing ability. 11. What is the shortest type of memory mentioned in the passage? A. Long-term memory. B. Short-term memory. C. Sensory memory. D. Working memory. 12. According to the passage, how long does short-term memory usually last? A. A few seconds. B. 15 to 30 seconds. C. Several days. D. A lifetime. 13. What happens to information during sleep according to the passage? A. It is completely lost. B. It enters long-term memory through consolidation. C. It is stored in the sensory memory. D. It is mixed with other memories. 14. What does the hippocampus help with? A. Remembering physical skills like riding a bike. B. Forming new memories. C. Storing all types of memories. D. Processing sensory information. 15. What is the best title for this passage? A. The Importance of Sleep for Memory B. Three Types of Memory and How They Work C. How to Improve Your Short-Term Memory D. The Brain's Most Important Function The Power of Memory in Animals For a long time, scientists believed that only humans had complex memories. However, recent research has shown that many animals also have impressive memory abilities that help them survive in the wild. Take squirrels, for example. These small animals store hundreds of nuts in different places during autumn. What is surprising is that they can remember the exact locations of these nuts months later, even under thick snow. Scientists wondered how they could remember so many locations. They discovered that squirrels use a technique similar to creating a mental map. They remember not only where they hid the nuts but also what the area looked like at the time. Elephants are another example of animals with extraordinary memory. They can remember other elephants they have not seen for many years. They also remember the routes to water sources that they used decades ago. This is why older elephants often lead the herd — they know where to find food and water during dry seasons. In addition, elephants can recognize human voices. They can tell the difference between the voices of different ethnic groups and react differently to them. Dolphins also show impressive memory skills. They can remember the unique whistles of other dolphins even if they have not met for more than 20 years. Each dolphin has its own special whistle, like a human name, and they use these whistles to call each other. Scientists believe that studying animal memory can help us understand human memory better. Animals and humans may use similar brain processes to store and recall information. So next time you forget something, remember that even the cleverest animals sometimes need to work hard to remember, too! --- 16. Where do squirrels store their nuts? A. In a single place. B. In different locations. C. In their homes only. D. Under the water. 17. What technique do squirrels use to remember their hiding places? A. They write down the locations. B. They create a mental map. C. They ask other squirrels for help. D. They use smell to find the nuts. 18. Why do older elephants often lead the herd? A. They are stronger than younger elephants. B. They remember the routes to water and food C. They can run faster than the rest of the herd. D. They are better at protecting the young. 19. According to the passage, what can dolphins remember? A. The faces of other dolphins. B. The unique whistles of other dolphins. C. The names of their trainers. D. The routes to different oceans. 20. What is the main idea of this passage? A. Only humans have good memories. B. Squirrels are smarter than elephants. C. Many animals have impressive memory abilities. D. Animal memory is not worth studying. A Grandmother's Memory My grandmother, Grandma Li, is 82 years old. She has a heart full of stories and a mind that remembers things in surprising ways. Sometimes she forgets where she put her glasses, but she can still tell you every detail of her childhood in a small village in Sichuan. Last summer, I visited her during the holidays. She showed me an old, yellowed photograph of a group of young women standing in front of a wooden house. "That's me and my classmates," she said with a smile. "We were 15 years old then. Can you find me?" It took me a moment, but I pointed to a girl with two long braids. Grandma laughed and said, "That's right! I remember that day clearly. We had just finished a performance for the Spring Festival. I was wearing my favourite red coat." Grandma also remembers things that I have long forgotten. She recalls the names of my childhood friends, the games we played, and even the songs I used to sing. Whenever I visit, she tells me stories that bring back memories I thought were lost. My mother says that Grandma's memory for past events is like a treasure box — she keeps everything safe inside. However, Grandma does forget things in daily life. She sometimes calls me by my mother's name. She also forgets whether she has taken her medicine. But my family does not worry too much. We understand that as people get older, their short-term memory often weakens, but their long-term memory for past events can remain very strong. I have learned from Grandma that memory is not just about remembering facts. It is also about remembering the people we love and the moments that shape our lives. Those are the memories that truly matter. 21. Where is Grandma Li from originally? A. A big city in China. B. A small village in Sichuan. C. A town in northern China. D. A village near Shanghai. 22. What does the photograph show? A. Grandma Li with her family. B. Grandma Li with her classmates. C. Grandma Li's wedding day. D. Grandma Li's performance on stage. 23. What does Grandma Li sometimes forget? A. The names of her childhood friends. B. The songs she used to sing. C. Where she put her glasses. D. The details of her childhood. 24. What does Grandma Li's daughter say about her memory? A. She should see a doctor. B. Her memory is like a treasure box. C. She needs to write things down. D. Her memory is getting worse quickly. 25. What lesson does the author learn from Grandma Li? A. Old people always have bad memory. B. Memory is only about remembering facts. C. The most important memories are about loved ones and meaningful moments. D. It is impossible to remember things from childhood. 三、六选五（共5小题，每小题2分，满分10分） 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有一项为多余选项。 Ways to Keep Your Memory Sharp Memory loss is a common concern as people get older.
