Ⅳ.阅读还原
根据短文内容,从方框中选择适当的选项补全短文,选项中有一项为多余选项。
From English words to historical events, you have to remember a lot at school. Is it difficult? Do you want to find some good ways to remember easily and quickly? If you have a photographic memory（过目不忘的记忆力）, will things be different? Scientists have made an effort to find ways to improve our memories for years. 13
Sleeping in a rocking bed
When we were babies, we could easily fall asleep in our mothers' swaying（摇晃）arms. Some scientists
have found that if we sleep in a bed which moves softly forwards and backwards, we can have a deeper sleep. 14 Buying a rocking bed may be a good idea and it must be very fun. Haha!
Becoming emotional
Thinking back to the past, it seems that we could always remember those things that make us sad or happy easily. Why? 15 The moment you become emotional, you can remember things really well because the amygdala（杏仁核）in our brain is responsible for dealing with both emotions and memories. The brain wants us to remember those things. When you want to remember some knowledge next time, try to make yourself angry or excited. Then, take out your book to catch the chance to learn new things.
16
In an experiment（实验）, scientists divided 100 people into two groups. People in the first group were asked to ride a bike slowly for 60 minutes. People in the second group only had to do it really fast for 6 minutes. It shows that the short but intense（剧烈的）exercise made the brain produce more of a chemical called brain-derived neurotrophic factor（脑源性神经营养因子）. People can remember things quickly with this chemical. 17 That's the time when you need to sit down and start to remember things.
A.Having intense exercise
B.Drinking more water
C.Here are some tips from their findings.
D.Its amount（数量）goes to the highest point after six minutes of intense exercise.
E.It can improve our memories as well.
F.Because emotions can influence memories.
13. 14. 15. 16. 17.

[语篇解读] 本文主要介绍了一些提高记忆力的方法。
13.C 根据“Scientists have made an effort to find ways to improve our memories for years.”及下文介绍可知,这里是一个承上启下的句子,C 选项“以下是从他们的调查发现中得出的一些建议”符合语境,故选 C。
14.E 根据“Some scientists have found that if we sleep in a bed which moves softly forwards and backwards, we can have a deeper sleep.”可知,在一张前后轻轻移动的床上,我们可以睡得更沉,结合首段中的“find ways to improve our memories”可知,睡摇床与提高记忆力有关,E 选项“它也可以提高我们的记忆力”符合语境,故选 E。
15.F 根据“Why?”可知,此处应用 because 回答;结合“The moment you become emotional, you can remember things really well”可推知,情绪会对记忆力有影响,F 选项“因为情绪会影响记忆力”符合语境,故选 F。
16.A 根据“It shows that the short but intense exercise made the brain produce...”可知,本段的建议与做运动有关,A 选项“进行剧烈运动”符合语境,故选 A。
17.D 根据“That's the time when you need to sit down and start to remember things.”可知,此处提到了某个时间点,D 选项“它的数量在 6 分钟的高强度运动后达到最高点”符合语境,故选 D。

【分析】
这是一道英语阅读还原题，解题思路为：先通读全文把握主旨（介绍提高记忆力的方法），再逐个分析每个空格的上下文逻辑关系，结合选项的语义、衔接性及段落概括性，选出符合语境的选项，重点关注句子间的因果、承上启下、指代等逻辑。
【解析】
1. 第13空：前文提到科学家多年来寻找提高记忆力的方法，后文开始介绍具体方法，需承上启下的句子，C选项“以下是从他们的调查发现中得出的一些建议”符合语境，故选C。
2. 第14空：前文指出睡在轻摇的床上能睡得更深，结合文章主题“提高记忆力”，E选项“它也可以提高我们的记忆力”承接上文说明睡摇床的额外作用，故选E。
3. 第15空：前文用“Why?”提问，需用because引导的句子回答，且后文提到情绪影响记忆，F选项“因为情绪会影响记忆力”符合因果关系，故选F。
4. 第16空：该空为段落标题，后文围绕“短时间剧烈运动产生提高记忆的化学物质”展开，A选项“进行剧烈运动”概括本段内容，故选A。
5. 第17空：前文提到剧烈运动产生的化学物质，后文说“那是需要开始记忆的时间”，D选项“它的数量在6分钟的高强度运动后达到最高点”对应时间点，符合语境，故选D。
