But if you find yourself always forgetting where you put your keys or what your homework is, it might be time to change some habits. Here are some science-backed ways to improve your memory. ▲ Use your senses. When you are trying to remember something new, try to connect it with your senses. For example, if you meet a new person named Daisy, picture a daisy flower (雏菊) in your mind. If you are trying to remember to buy milk, imagine the cold feeling of the milk bottle. The more senses you use, the stronger the memory will be. Don’t multitask. Many students like to listen to music, chat online, and do homework at the same time. But scientists say multitasking is bad for memory. When your attention is divided, your brain can’t process information deeply. It is better to focus on one thing at a time. Teach someone else. This is a powerful method. If you want to remember a piece of knowledge firmly, try explaining it to your deskmate. When you teach, you have to organize the information clearly in your mind. This process helps move the information from short-term memory to long-term memory. Change your environment. Studying in the same quiet room is good, but sometimes a change of scene helps. A study showed that students who studied the same material in two different rooms remembered 20% more than those who stayed in one room. This is because different environments provide different “cues” (线索) for your brain. Remember, improving memory is like building muscles. It takes time and practice. Start with one tip today! 12. Which sentence should be put in “ ▲ ” in the paragraph about using senses? A. Milk is white and good for health. B. Daisy smells sweet and grows in spring. C. Hello, Daisy! Nice to meet you. D. I like flowers very much. 13. According to the passage, why is multitasking bad for memory? A. Because it makes us feel tired quickly. B. Because it divides our attention. C. Because it makes the environment noisy. D. Because it takes too much time. 14. What can we learn from the passage? A. Studying in different rooms can help us remember more. B. Listening to music while studying is always helpful. C. Teaching others is the easiest way to learn. D. We should focus on three things at a time. 15. （篇章结构题） Which shows the structure of the passage? (P=Paragraph) A. P1: Introduction → P2-P5: Methods → P6: Conclusion B. P1: Problem → P2-P5: Reasons → P6: Solution C. P1: Question → P2-P5: Examples → P6: Summary D. P1: Fact → P2-P5: Arguments → P6: Opinion 16. （写作目的题） What is the main purpose of this passage? A. To tell us why we forget things. B. To introduce some ways to improve memory. C. To advise us to study in different rooms. D. To explain how our brain works. Ⅳ. 阅读还原 「2026 江西南昌二中月考改编」 请认真阅读下面短文，从短文后的选项中选出能填入空白处的最佳选项。选项中有一项为多余选项。 Do you know that chewing gum (嚼口香糖) might help you concentrate and remember things better? A study from the University of Northumbria suggests that chewing gum can improve memory and alertness (警觉性). In the study, 75 volunteers took part in memory tests. 17 Some were given gum to chew during the test, while others were not. The results showed that the gum-chewers had better concentration and performed better on memory tasks. 18 Scientists believe there are several reasons for this. First, chewing increases the heart rate. 19 Second, the act of chewing might increase blood flow to the brain. More blood means more oxygen, which helps the brain work better. 20 However, experts warn that you shouldn't chew gum all the time. Chewing too much can cause jaw pain (下巴痛). Also, it might be impolite to chew gum during a class or a meeting. So, if you have an important exam coming up, maybe grab a piece of gum. 21 Just remember to throw it in the bin after you finish! A. This sends more oxygen to the brain. B. But don't chew it during the whole day. C. They were asked to remember a list of numbers. D. This is because it keeps your mouth busy. E. It seems that a simple stick of gum can make a difference. F. The volunteers who didn't chew gum felt more relaxed. 17. ______ 18. ______ 19. ______ 20. ______ 21. ______ 参考答案及解析 Ⅰ. 用括号内所给词的适当形式填空 1. views （share one's views 分享某人的观点，常用复数） 2. reading （by是介词，后接动名词doing） 3. effectively （修饰动词improve，用副词effectively） 4. discussion （a heated discussion 一场激烈的讨论，冠词后接名词） 5. to forget （be likely to do sth. 固定搭配，可能做某事） Ⅱ. 根据汉语意思完成句子 6. fail to （fail to do sth. 未能做某事） 7. First of all （首先，固定短语） 8. wear out （磨损，will后接动词原形） 9. After all （毕竟，固定短语） 10. Last but not least （最后但同样重要的是，固定短语） 11. make it convenient （make it + adj. + for sb. to do sth. 使做某事对某人来说……） Ⅲ. 阅读理解 12.

A （由第五段“students who studied...in two different rooms remembered 20% more...”可知） 15. A （P1引出话题，P2-P5分别介绍四种方法，P6总结，属于“总-分-总”结构） 16. B （文章主要目的是介绍几种科学的提高记忆力的方法） Ⅳ. 阅读还原 17.
