Scientists say this is because of the difference between “automatic memory” and “active memory”. Automatic memory stores information we use very often, like our home address, parents’ names, or how to ride a bike. We don’t need to try to remember these things—our brain keeps them forever because we use them again and again. That’s why you can still sing the alphabet song（字母歌）even if you haven’t sung it for years. Active memory, however, needs attention. It holds new information for a short time, like a shopping list or a new classmate’s name. If we don’t focus on it or repeat it, it disappears quickly. For example, if someone tells you a phone number and you don’t write it down or say it aloud, you’ll probably forget it in 20 seconds. A study at Harvard University found that active memory can hold about 7 pieces of information at a time. But this changes if we use “chunking”（组块法）. Chunking means grouping small bits of information into larger units. For example, remembering a 10-digit number like 13812345678 is hard. But if you break it into chunks—138-1234-5678—it becomes much easier. This is why memory champions often use chunking to remember long lists of words or numbers. Interestingly, stress and lack of sleep can hurt active memory. When we are worried or tired, our brain can’t process new information well. So, if you want to remember something important, stay calm and get enough rest! Understanding how these two types of memory work can help us study smarter and avoid forgetting things in our daily lives. 20. What is the main difference between automatic memory and active memory? A. Automatic memory lasts long, while active memory is short-lived. B. Active memory stores phone numbers, while automatic memory stores names. C. Automatic memory needs attention, while active memory doesn’t. D. Active memory is used for riding bikes, while automatic memory is not. 21. Why can we still remember our childhood phone number? A. Because it is stored in active memory. B. Because we use it very often. C. Because it is easy to remember. D. Because we wrote it down many times. 22. What does the underlined word “disappears” in Paragraph 3 mean? A. 出现 B. 储存 C. 消失 D. 重复 23. According to the passage, what is “chunking”? A. Repeating information again and again. B. Breaking large units into small bits. C. Grouping small bits into larger units. D. Writing down information quickly. 24. What is the best title for the passage? A. How to Remember Phone Numbers Quickly B. The Importance of Sleep for Memory C. Automatic Memory vs. Active Memory D.
