Five Tips to Improve Your Memory
Most of us know that our brains(大脑) become smaller in size as we get older, but do you know that diet and lifestyle have an effect on how well our brains work?
Research shows that eating lots of fruit, vegetables and proteins(蛋白质) improves memory. 1 Eating oily fish or dark chocolate (with over 70% cocoa) and taking Vitamin D3 can also help make your memory stronger.
2 A 2011 study showed that regular exercise actually increased brain size. Another study found that exercise improved memory of some older people; surprisingly it found that one single training period had the same effect on memory as a regular, long exercise period!
One study found that eight weeks of short, daily meditation(冥想) improved memory. Other ways to relax can also improve our short-term memory. Try taking 5-10 minutes of your day to meditate or listen to music. 3
Experts say that age reduces our ability to learn, but sleep can help. 4 A 2019 study found that students learnt things better after a short sleep!
5 Try to memorize information like phone numbers and addresses rather than putting the information in your phone. You could also learn a language or do brain training like crosswords(填字游戏).
A. Or even just take a shower!
B. It's important to keep a healthy body.
C. The role of exercise is really important too.
D. Use your phone to help you memorize things.
E. To keep your brain in good condition, you need to use it.
F. Try to avoid sugary foods such as cakes and milk chocolate.
G. For your brain to work well, 7-9 hours of sleep is necessary.
1. 2. 3. 4. 5.

【文章大意】本文是一篇说明文,主要介绍提高记忆力的五个建议。
1. F 根据“Research shows that eating lots of fruit, vegetables
and proteins improves memory ... Eating oily fish or dark
chocolate (with over 70% cocoa) and taking Vitamin D3 can
also help make your memory stronger.”可知,此处与饮食相关,

用也很重要。”符合语境,故选C。
3. A 根据“One study found that eight weeks of short, daily
meditation improved memory. Other ways to relax can also
improve our short-term memory. Try taking 5—10 minutes of

的大脑处于良好状态,你需要使用它。”符合语境,故选E。

【分析】
这是一篇说明文类的七选五题型，解题思路可以按以下步骤走：第一步先通读全文，明确文章核心主题是介绍5种提升记忆力的方法，整体结构是每段对应一个独立的建议，每段有明确的核心话题。第二步逐空定位前后文的核心关键词，匹配话题一致的选项：第1空前后都在讲饮食对记忆力的影响，找和健康饮食相关的选项即可；第2空后文全部围绕运动的相关研究展开，选引出运动重要性的主题句；第3空前文在列举放松的不同方式，选属于放松方法的并列选项；第4空前后都围绕睡眠对记忆、学习的作用展开，选和健康睡眠时长相关的内容；第5空后文都在讲主动做脑力训练，选对应“要主动使用大脑”的主题句，最后排除剩下的无关干扰项就能得到正确答案。
【解析】
1. 第1空前后内容都围绕饮食对记忆力的作用展开，前文提到多吃水果、蔬菜、蛋白质可以提升记忆力，后文提到食用多脂鱼、可可含量超70%的黑巧克力、补充维生素D3也能强化记忆，F选项“尽量避免含糖食物，如蛋糕和牛奶巧克力”同样属于健康饮食的相关建议，完美衔接上下文饮食类内容，符合语境。
2. 第2空后整段都围绕运动对大脑和记忆力的积极影响展开，先后列举了2011年运动增大脑容量、运动改善老年群体记忆力的两项研究，C选项“锻炼的作用也很重要”作为本段的主题句，引出后文所有和运动相关的论述，符合语境。
3. 第3空前文提到多种放松方式都可以改善短时记忆，已经举例了每日短时间冥想、听音乐的放松方法，A选项“或者只是洗个澡！”是另一种并列的放松方式，和前文列举的放松方法呼应，符合语境。
4. 第4空前文提到睡眠可以缓解年龄增长带来的学习能力下降问题，后文提到2019年的研究显示短时间睡眠后学生的学习效果更好，G选项“为了让大脑正常工作，7-9小时的睡眠是必要的”衔接前后关于睡眠作用的内容，符合语境。
5. 第5空后文建议人们主动记忆电话号码、地址，学习语言、做填字游戏等脑力训练，E选项“为了让你的大脑处于良好状态，你需要使用它”作为本段主题句，引出后文所有主动用脑、锻炼大脑的相关建议，符合语境。
【答案】
1. F 2. C 3. A 4. G 5. E
【知识点】
说明文阅读，七选五题型，逻辑语境衔接
【点评】
本题属于典型的建议类说明文七选五，每段核心话题区分度较高，学生可以通过定位段落主题词快速缩小选项范围，剩余的两个干扰项和各段核心话题匹配度很低，整体能有效锻炼学生抓取段落主旨、梳理句间逻辑关联的阅读能力。
