A．how to solve B．to solve C．solve D．solving 【答案】A 【详解】句意：没有人知道如何完全解开这个记忆之谜。 动词know后可接“疑问词+动词不定式”，在句中作宾语，how to solve符合语法结构与句子语义，其余选项无法直接跟在know后构成合乎逻辑的表达。 2. I wonder ____ this memory technique（技巧）really works. I want to give it a try. A. that B. if C. which D. what 【答案】B 【解析】考查宾语从句引导词if。"wonder"意为"想知道"，后接"是否"含义的从句，用if。A项that表陈述事实逻辑不通，C/D项与从句结构不匹配。故选B。 3．I’m not sure ________ he will come to the party or not. A．that B．if C．whether D．what 【答案】C 【详解】句意：我不确定他是否会来参加聚会。 that引导陈述句（无意义）；if是否；whether是否；what什么。根据“or not”常与whether搭配，构成whether...or not结构，表示“是否”，应填whether。 4．The ________ of the accident are still under investigation.

A．hear B．hearing C．heard D．hears 【答案】B 【详解】句意：我期待着收到我笔友的来信。 固定短语look forward to doing sth.表示“期待做某事”，to是介词，后接动名词hearing。 7．________ English words every day is a good way to improve your memory. A．Memorize B．Memorizing C．Memorized D．Memorizes 【答案】B 【详解】句意：每天记忆英语单词是提高记忆力的一个好方法。 根据句子结构可知，空处位于句首作主语，动词不能直接作主语，应用动名词形式Memorizing，谓语动词用单数is。 8．You should ________ all the important points when learning new knowledge. A．mix up B．keep in mind C．give up D．cheer up 【答案】B 【详解】句意：学习新知识时，你应该记住所有的要点。 mix up混淆，弄乱；keep in mind牢记，把……记在心里；give up放弃；cheer up振作起来，使振奋。根据“all the important points when learning new knowledge”以及选项可知，此处指记住所有的要点，应用keep in mind。 9．Doing exercise regularly can make our brain more ________ and help us remember things faster. A．forgetful B．active C．stressed D．sad 【答案】B 【详解】句意：定期做锻炼能使我们的大脑更加活跃，帮助我们更快地记住事情。 forgetful健忘的；active活跃的；stressed有压力的；sad悲伤的。根据后半句“help us remember things faster”可知，锻炼对大脑有积极作用，能提升记忆力。forgetful、stressed和sad均为负面词汇，与语境不符；active意为“活跃的”，符合语境。 10．I believe that ________ you keep practicing these useful methods, your memory will become better. A．as long as B．even though C．so that D．as far as 【答案】A 【详解】句意：我相信只要你坚持练习这些实用的方法，你的记忆力就会变得更好。 as long as只要；even though即使；so that以便；as far as就……而言。句子前半句是条件，表达“只要坚持练习，记忆力就会提升”，as long as符合语境。 二、完形填空（本大题共20小题，共20分）。 A There is a saying that "an elephant never forgets" and research has shown this is somewhat true. Elephants are very good at remembering which animals are friendly and which are dangerous. Older 1 use this skill to keep the rest of their group safe from dangers. Squirrels also have quite good memories. In autumn, they bury lots of nuts in the ground to 2 them for winter. They depend on their memory and sense of smell to find the nuts and dig them back up to eat them. What about the other animals? Do they have a good memory? Scientists have tested how 3 goats, sheep and alpacas could remember where food was hidden. In one experiment, they placed food under two out of eight buckets in an area. The animals were then brought back later to see if they could 4 which buckets held the food. The goats found the food fastest and made 5 mistakes. Sheep struggled more, while alpacas were slow and often couldn’t finish in 6 . In another test, food was hidden under cups that were moved or mixed with empty ones. Goats still 7 . They easily remembered where the food was even when things changed. Sheep and alpacas, however, had 8 following the cups once they moved. The tests show that goats are 9 and have better memories than sheep and alpacas. Farm animals might be cleverer than we realize. It seems that memory plays an important 10 in the animal world. 1．A．elephants B．squirrels C．goats D．sheep 2．A．sell B．store C．share D．plant 3．A．soon B．often C．well D．long 4．A．forget B．change C．remember D．hide 5．A．more B．fewer C．bigger D．louder 6．A．danger B．silence C．time D．surprise 7．A．excelled B．failed C．slept D．left 8．A．fun B．luck C．trouble D．interest 9．A．slower B．smarter C．weaker D．younger 10．A．game B．joke C．trick D．role 【答案】 1．A 2．B 3．C 4．C 5．B 6．C 7．A 8．C 9．B 10．D 【导语】本文主要介绍了大象、松鼠及山羊等动物的记忆力。通过科学实验对比，表明山羊记忆力较好，记忆在动物界很重要。 【详解】 1．句意：年长的大象利用这种技能保护族群的安全，让它们远离危险。 根据第一段首句"There is a saying that ‘an elephant never forgets’"及上下文逻辑，可知此处指大象。elephants"大象"符合，squirrels"松鼠"、goats"山羊"和sheep"绵羊"为其他段落提到的动物，不符合本段语境。 2．句意：秋天，它们把很多坚果埋在地里 就是为了储存它们过冬。 根据"bury lots of nuts"和"for winter"可知，埋坚果是为了储存食物过冬，store"储存"符合，sell"卖"、share"分享"和plant"种植"不符合松鼠过冬的习性逻辑。 3．句意：科学家测试了山羊、绵羊和羊驼能多好地记住食物藏在哪。 根据"tested how...could remember"可知，测试的是记忆能力的好坏。well"好"修饰动词remember，强调记忆力很好，soon"很快"、often"经常"和long"长"侧重频率或时间，不符合测试能力的语境。 4．句意：这些动物稍后被带回来看看它们能否记得哪个桶里有食物。 根据前文"memory tests"及实验目的，可知是测试它们是否能"记得"，remember"记得"符合语境，forget"忘记"、change"改变"和hide"藏"不符合该实验逻辑。 5．句意：山羊找到食物最快且犯的错误更少。 根据"found the food fastest"可知山羊表现最好，因此错误应该"更少"，fewer"更少"修饰名词mistakes。more"更多"、bigger"更大"和louder"更大声"不符合语境。 6．句意：绵羊则要更吃力，而羊驼很慢且经常不能按时完成。 根据"slow"和"finish"可知，此处指无法在限定"时间"内完成，time"时间"符合。danger"危险"、silence"沉默"和surprise"惊讶"不符合语境逻辑。 7．句意：山羊的表现依旧十分出色。 根据后句"They easily remembered where the food was"可知，山羊能很容易记住食物的位置，说明它们做得很好，excelled"表现优异"符合语境，failed"失败"、slept"睡觉"和left"离开"不符合语境。 8．句意：然而，一旦杯子移动，绵羊和羊驼就很难跟得上杯子。 根据"however"表示转折，前文山羊表现好，此处应指绵羊和羊驼有"困难"，trouble"困难"符合语境，fun"乐趣"、luck"运气"和interest"兴趣"不符合转折后的消极语境。 9．句意：测试表明山羊更聪明，且记忆力比绵羊和羊驼更好。 根据"have better memories"及全文主旨，可知记忆力好意味着"更聪明"，smarter"更聪明的"符合语境，slower"更慢的"、weaker"更弱的"和younger"更年轻的"不符合语境。 10．句意：似乎记忆在动物界扮演着重要的角色。 根据"play an important...in"可知，play a role为固定搭配，意为"扮演角色/起作用"，role"角色/作用"符合语境，game"游戏"、joke"笑话"和trick"诡计"不符合语境。 B How good is your memory? Can you remember what you ate for breakfast a week ago? Most people find it 11 to remember every detail of their lives. However, our brains are wired to remember what is important for survival. In the past, remembering where to find food or which places were dangerous was a matter of life and death. Today, we don’t face those same 12 , but our memory still works in a similar way. We tend to remember things that are 13 to us—like a friend’s birthday or an important exam date. Scientists have found that our memory works in two main ways: short-term and long-term. Short-term memory holds information for a few seconds, like a phone number you just 14 . Long-term memory stores information for years, like your childhood address. To move information from short-term to long-term memory, we need to 15 it. This is why reviewing your notes after class is so important. 16 , memory is not like a video recording. It can be changed over time. Every time we 17 a memory, we might accidentally change a small detail. This is why eyewitness (目击者) accounts can sometimes be unreliable (不可靠的). 18 , understanding how memory works can help us improve it. Techniques like “spaced repetition” and “mind maps” are not just study tips; they are ways to work 19 our brain’s natural processes. So, the next time you forget where you put your keys, don’t be too hard on yourself. It’s just your brain’s way of deciding what 20 keeping. 11．A．easy B．impossible C．necessary D．helpful 12．A．problems B．dangers C．questions D．changes 13．A．boring B．strange C．important D．similar 14．A．heard B．wrote C．missed D．forgot 15．A．repeat B．change C．ignore D．create 16．A．However B．Therefore C．Besides D．Instead 17．A．forget B．recall C．lose D．store 18．A．Finally B．Suddenly C．Luckily D．Sadly 19．A．against B．with C．for D．without 20．A．starts B．avoids C．practices D．deserves 【答案】 11．B 12．B 13．C 14．A 15．A 16．A 17．B 18．C 19．B 20．D 【导语】本文是一篇说明文，解释了人类记忆的两种主要方式（短期和长期记忆）以及记忆的可变性，并提供了一些利用大脑自然机制来改善记忆的方法。 【详解】11．句意：大多数人发现要记住他们生活中的每一个细节是不可能的。 前文提问“你能记住一周前早餐吃了什么吗？”暗示大多数人无法记住所有细节，因此应用impossible（不可能的）。easy意为“容易的”，necessary意为“必要的”，helpful意为“有帮助的”，均不符合“记不住”的普遍情况。 12．句意：今天，我们不再面对同样的危险……。 前文提到过去记住食物地点和危险地点是生死攸关的事，现在生存威胁减少，因此应用dangers（危险）。problems意为“问题”，questions意为“问题（疑问）”，changes意为“变化”，均不能准确对应“生命危险”的具体内容。 13．句意：我们倾向于记住对我们重要的事情——比如朋友的生日或重要的考试日期。 生日和考试日期对个人具有重要性，应用important（重要的）。boring意为“无聊的”，strange意为“奇怪的”，similar意为“相似的”，均不符合这些例子的特征。 14．句意：短期记忆保存信息几秒钟，比如你刚刚听到的电话号码。 刚听到的电话号码在短期记忆中停留片刻，应用heard（听到）。wrote意为“写下”，missed意为“错过”，forgot意为“忘记”，均不符合“刚获得信息”的短暂保存情境。 15．句意：为了把信息从短期记忆转移到长期记忆，我们需要重复它。 后文提到课后复习笔记的重要性，说明需要“重复”来巩固，应用repeat（重复）。change意为“改变”，ignore意为“忽视”，create意为“创造”，均不能解释“复习”的作用。 16．句意：然而，记忆不像录像。 前文讲述记忆的转化机制，后文指出记忆会随时间变化，二者是转折关系，应用However（然而）。Therefore意为“因此”，Besides意为“此外”，Instead意为“相反”，均不符合转折逻辑。 17．句意：每次我们回忆一段记忆，我们可能会不小心改变一个小细节。 回忆时可能改变细节，应用recall（回忆）。forget意为“忘记”，lose意为“丢失”，store意为“储存”，均不能与“改变细节”构成因果关系。 18．句意：幸运的是，理解记忆如何工作可以帮助我们改进它。 前文提到记忆不可靠，后文说理解机制能帮助改进，是积极转向，应用Luckily（幸运地）。Finally意为“最终”，Suddenly意为“突然”，Sadly意为“悲伤地”，均不能表达这种幸运的转折。 19．句意：像“间隔重复”和“思维导图”这类技巧不只是学习小窍门，更是顺应我们大脑自然运作规律的方法。 “work with”表示“与……配合”，即顺应大脑的运作方式。against意为“反对”，for意为“为……”，without意为“没有”，均不符合“利用自然过程”的含义。 20．句意：这只是你大脑决定什么值得保留的方式。 “deserves keeping”表示“值得保留”，应用deserves。starts意为“开始”，avoids意为“避免”，practices意为“练习”，均不能表达“有价值而保留”的含义。 三、阅读理解（本大题共15小题，共30分）。 A We all forget things. But scientists say sleep is like a save button for our brain. In a study, two groups of students tried to memorize 20 new words. Group A reviewed them at 9 p.m. and went to sleep. Group B reviewed at 9 p.m. but stayed awake playing games. The next morning, Group A remembered 15 words on average, while Group B only remembered 9.   Why? During sleep, especially deep sleep, the brain repeats the day’s information. It moves facts from short-term memory to long-term memory. That is why you can recall a poem better after a good night’s rest.   However, watching screens before bed harms this process. The blue light stops the brain from relaxing. Also, cramming all night never works as well as spaced study plus sleep.   Schools should teach students to respect sleep. A teenager needs about 8 hours. If you sleep well, your memory becomes sharper, and you feel happier in class. 1．What did Group A do after reviewing words? A．Played games. B．Went to sleep. C．Watched TV. D．Ran outside. 2．The underlined word “sharper” in the last paragraph means ______. A．更敏锐 B．更困倦 C．更缓慢 D．更庞大 3．Why does the brain repeat information during sleep? A．To make people dream. B．To move facts to long-term memory. C．To stop blue light. D．To play games. 4．What is the writer’s suggestion to students? A．Stay up late to study. B．Respect sleep and do spaced study. C．Watch screens before bed. D．Never review. 5．What is the best title for the passage? A．The Magic of Sleep on Memory. B．How to Play Games. C．Why We Dream. D．Group Study Wins. 【答案】1．B 2．A 3．B 4．B 5．A 【导语】本文借助实验说明睡眠有助于巩固记忆，睡前看电子屏幕不利于记忆，建议学生重视睡眠，采用间隔学习配合睡眠的方式学习。 【详解】1．第一段指出：“Group A reviewed them at 9 p.m. and went to sleep.”，说明A组复习单词之后就去睡觉了。 2．最后一段指出：“If you sleep well, your memory becomes sharper, and you feel happier in class.”，结合语境，睡眠充足会让记忆力变得更好，因此sharper含义为更敏锐。 3．第二段指出：“During sleep…the brain repeats the day’s information. It moves facts from short-term memory to long-term memory.”，说明大脑在睡眠中重复信息是为了将信息转化为长期记忆。 4．第三段指出：“cramming all night never works as well as spaced study plus sleep”，第四段指出：“Schools should teach students to respect sleep.”，由此得出作者建议重视睡眠并且进行间隔学习。 5．全文围绕睡眠对记忆力的作用展开实验与讲解，此标题可以概括全文中心，其余选项和文章主题无关。 B Do you think it’s hard to remember things? Do you often forget where you put your erasers? According to many studies, some foods are good for your memory. Why not try them? Scientists have found that vitamin B2 can improve your memory. It’s found in common things like milk and dark green vegetables You can have a banana for breakfast. It will be easier for you to focus on what the teachers say. Studies have shown that eating fish once a week produces a 10 percent slower decline (衰退) in memory. We know that eggs are full of vitamin B12. It helps to fight against brain shrinkage (收缩). If you’re really serious about your memory, don’t forget to make time for a good breakfast. A study found breakfast helped people score better on memory tests. You are what you eat.” A healthy eating habit is great for your body. What’s more, junk foods like cola, fried chips and candies are bad for your health and memory.

A．diary B．dictionary C．newspaper D．storybook 【答案】6．A 7．C 8．B 9．B 10．C 【导语】本文是一篇说明文，主要介绍了牛奶、香蕉、鱼类、鸡蛋四种有益于记忆力的食物，同时强调早餐的重要性，提醒远离损害记忆的垃圾食品。 【详解】6．表格右上角香蕉板块“You can have a banana for your breakfast. It will be easier for you to focus on what the teachers say.”，说明香蕉能让人集中注意力，适合犯困时上课。 7．表格左下角鱼类板块“eating fish once a week produces a 10 percent slower decline in memory.”，吃鱼可以帮助减缓记忆力衰退，和C选项表述一致。 8．表格右下角鸡蛋板块“eggs are full of vitamin B12. It helps to fight against brain shrinkage.”，B12可以帮助阻止大脑萎缩。 9．最后一段第一句“don’t forget to make time for a good breakfast. A study found breakfast helped people score better on memory tests.”，整段核心论述早餐对记忆的重要性，对应B选项。 10．文章科普健康饮食知识，这类短文最常刊登在报纸健康版面。 C.任务型阅读 Remember to eat fruits and vegetables. They might just improve your memory. Scientists have found out several kinds of products—including vegetables which have green leaves, orange and red vegetables, berries and orange juice, are good for memory. Researchers at Harvard University have found that men who insisted on eating those fruits and vegetables over a period of 20 years were more likely to have better memory skills than those who seldom ate them. The study followed about 27,800 men in health care jobs over 20 years, and surveyed them on their diets and other health-related topics every four years. Toward the end of the study, the researchers started asking them questions about their memory. For example, “Do you have more trouble than usual remembering a short list of things, such as a shopping list?” or “Do you have more trouble than usual following a group conversation or a story in a TV program because of your memory?” “A growing number of ‘yes’ answers to such questions can mean their memory is going down,” the researchers said. The participants (参与者) were divided into five groups, based on how many servings (分量) of vegetables and fruits they got each day, from six servings in the healthiest group to just two servings. The six-serving eaters were 34 percent less likely to be forgetful. And the results were even better if the men happened to eat carotenoid (类胡萝卜素)-rich vegetables, such as carrots and pumpkins. Besides, those who drank orange juice often were 47 percent less likely to become forgetful, compared with those who drank orange juice less than once a month. “Our study provides further evidence that diet choices can be important to keep your brain healthy,” researchers said. 11．How long did the researchers follow the participants in the study? ________________________________________ 12．According to the study, what vegetables are good for people’s memory? ________________________________________ 13．According to Paragraph 4, what can it mean when a person’s memory is becoming worse? ________________________________________ 14．What do the researchers think the study can prove? ________________________________________ 15．Would you start drinking orange juice more often? Why or why not? ________________________________________ 【答案】11．Over 20 years. 12．Green-leaf vegetables, orange and red vegetables, and carotenoid-rich vegetables like carrots and pumpkins. 13．A growing number of “yes” answers. 14．Diet choices can be important to keep your brain healthy. 15．Yes, because it helps improve memory. 【导语】本文是一篇说明文，主要讲述了哈佛大学研究人员通过一项长达20年的研究发现，多吃蔬菜和水果，特别是某些特定种类，有助于改善记忆力，保持大脑健康。 【详解】 11．根据文章第3段“The study followed about 27,800 men in health care jobs over 20 years”可知，研究人员跟踪参与者的时间超过了20年。 12．根据第二段整句“including vegetables which have green leaves, orange and red vegetables...”和第五段第三句“eat carotenoid-rich vegetables, such as carrots and pumpkins”，整合关键信息：绿叶蔬菜、橙红色蔬菜以及胡萝卜、南瓜这类富含类胡萝卜素的蔬菜，归纳整合可得出以上蔬菜都对记忆力有益。 13．根据文章第4段“A growing number of ‘yes’ answers to such questions can mean their memory is going down”可知，回答“是”的次数增多意味着记忆力变差。 14．根据文章第6段“Our study provides further evidence that diet choices can be important to keep your brain healthy”可推知，研究证明了饮食选择对大脑健康的重要性。 15．根据文章第5段“those who drank orange juice often were 47 percent less likely to become forgetful”可知，喝橙汁有助于减少健忘，改善记忆，所以此处可做肯定回答，并给出理由。答案不唯一，合理即可。 四、根据首字母或汉语提示填空。（本大题共10小题，共10分）。 1．This medicine is ________ (有效的) for your wound. 【答案】effective 【详解】句意：这个药对你的伤口有效。根据中文提示“有效的”，be动词is后面需要填形容词effective作表语，且be effective for表示“对……有效”，故填effective。 2．He has been feeling a lot of ________ (焦虑) over his new job. 【答案】anxiety 【详解】句意：他一直因为新工作感到十分焦虑。汉语提示为“焦虑”，对应名词anxiety；“a lot of”后可接可数名词复数或不可数名词，anxiety表内心焦虑情绪时为不可数名词。 3．It's l________ that he will forget the lecture time again. (可能的) 【答案】(l)ikely 【详解】句意：他很可能又会忘记讲座时间。由首字母及中文提示可知，固定句型It's likely that…"很可能……"符合语境，likely为形容词，意为"可能的"。 4．Many people in China enjoy watching traditional ________ (歌剧) with beautiful music. 【答案】operas 【详解】句意：许多中国人喜欢观看带有优美音乐的传统歌剧。括号内提示“歌剧”对应名词“opera”，此处泛指多种传统戏曲（如京剧、越剧等），故用复数形式“operas”。 5．My grandfather has a good memory and can ________ (复述) the story in his own words. 【答案】retell 【详解】句意：我的祖父记忆力很好，能够用自己的话复述这个故事。根据汉语提示，retell“复述”，置于情态动词之后，用原形即可。 5、 语法填空 (10分)。 Many people want to know how 1 (make) their memory better.

Elephants are very good at remembering which animals are friendly and which are dangerous. Older 1 use this skill to keep the rest of their group safe from dangers. Squirrels also have quite good memories. In autumn, they bury lots of nuts in the ground to 2 them for winter. They depend on their memory and sense of smell to find the nuts and dig them back up to eat them. What about the other animals? Do they have a good memory? Scientists have tested how 3 goats, sheep and alpacas could remember where food was hidden. In one experiment, they placed food under two out of eight buckets in an area. The animals were then brought back later to see if they could 4 which buckets held the food. The goats found the food fastest and made 5 mistakes. Sheep struggled more, while alpacas were slow and often couldn’t finish in 6 . In another test, food was hidden under cups that were moved or mixed with empty ones. Goats still 7 . They easily remembered where the food was even when things changed. Sheep and alpacas, however, had 8 following the cups once they moved. The tests show that goats are 9 and have better memories than sheep and alpacas. Farm animals might be cleverer than we realize. It seems that memory plays an important 10 in the animal world. 1．A．elephants B．squirrels C．goats D．sheep 2．A．sell B．store C．share D．plant 3．A．soon B．often C．well D．long 4．A．forget B．change C．remember D．hide 5．A．more B．fewer C．bigger D．louder 6．A．danger B．silence C．time D．surprise 7．A．excelled B．failed C．slept D．left 8．A．fun B．luck C．trouble D．interest 9．A．slower B．smarter C．weaker D．younger 10．A．game B．joke C．trick D．role B How good is your memory? Can you remember what you ate for breakfast a week ago? Most people find it 11 to remember every detail of their lives. However, our brains are wired to remember what is important for survival. In the past, remembering where to find food or which places were dangerous was a matter of life and death. Today, we don’t face those same 12 , but our memory still works in a similar way. We tend to remember things that are 13 to us—like a friend’s birthday or an important exam date. Scientists have found that our memory works in two main ways: short-term and long-term. Short-term memory holds information for a few seconds, like a phone number you just 14 . Long-term memory stores information for years, like your childhood address. To move information from short-term to long-term memory, we need to 15 it. This is why reviewing your notes after class is so important. 16 , memory is not like a video recording. It can be changed over time. Every time we 17 a memory, we might accidentally change a small detail. This is why eyewitness (目击者) accounts can sometimes be unreliable (不可靠的). 18 , understanding how memory works can help us improve it. Techniques like “spaced repetition” and “mind maps” are not just study tips; they are ways to work 19 our brain’s natural processes. So, the next time you forget where you put your keys, don’t be too hard on yourself. It’s just your brain’s way of deciding what 20 keeping. 11．A．easy B．impossible C．necessary D．helpful 12．A．problems B．dangers C．questions D．changes 13．A．boring B．strange C．important D．similar 14．A．heard B．wrote C．missed D．forgot 15．A．repeat B．change C．ignore D．create 16．A．However B．Therefore C．Besides D．Instead 17．A．forget B．recall C．lose D．store 18．A．Finally B．Suddenly C．Luckily D．Sadly 19．A．against B．with C．for D．without 20．A．starts B．avoids C．practices D．deserves 三、阅读理解（本大题共15小题，共30分）。 A We all forget things. But scientists say sleep is like a save button for our brain. In a study, two groups of students tried to memorize 20 new words. Group A reviewed them at 9 p.m. and went to sleep. Group B reviewed at 9 p.m. but stayed awake playing games. The next morning, Group A remembered 15 words on average, while Group B only remembered 9.   Why? During sleep, especially deep sleep, the brain repeats the day’s information. It moves facts from short-term memory to long-term memory. That is why you can recall a poem better after a good night’s rest.   However, watching screens before bed harms this process. The blue light stops the brain from relaxing. Also, cramming all night never works as well as spaced study plus sleep.   Schools should teach students to respect sleep. A teenager needs about 8 hours. If you sleep well, your memory becomes sharper, and you feel happier in class. 1．What did Group A do after reviewing words? A．Played games. B．Went to sleep. C．Watched TV. D．Ran outside. 2．The underlined word “sharper” in the last paragraph means ______. A．更敏锐 B．更困倦 C．更缓慢 D．更庞大 3．Why does the brain repeat information during sleep? A．To make people dream. B．To move facts to long-term memory. C．To stop blue light. D．To play games. 4．What is the writer’s suggestion to students? A．Stay up late to study. B．Respect sleep and do spaced study. C．Watch screens before bed. D．Never review. 5．What is the best title for the passage? A．The Magic of Sleep on Memory. B．How to Play Games. C．Why We Dream. D．Group Study Wins. B Do you think it’s hard to remember things? Do you often forget where you put your erasers? According to many studies, some foods are good for your memory. Why not try them? Scientists have found that vitamin B2 can improve your memory. It’s found in common things like milk and dark green vegetables You can have a banana for breakfast. It will be easier for you to focus on what the teachers say. Studies have shown that eating fish once a week produces a 10 percent slower decline (衰退) in memory. We know that eggs are full of vitamin B12. It helps to fight against brain shrinkage (收缩). If you’re really serious about your memory, don’t forget to make time for a good breakfast. A study found breakfast helped people score better on memory tests. You are what you eat.” A healthy eating habit is great for your body. What’s more, junk foods like cola, fried chips and candies are bad for your health and memory. You should try to keep away from them. 6．If Jenny feels sleepy, which food can help her focus on the morning math class? A．Bananas. B．Milk or vegetables. C．Fried chips.

They might just improve your memory. Scientists have found out several kinds of products—including vegetables which have green leaves, orange and red vegetables, berries and orange juice, are good for memory. Researchers at Harvard University have found that men who insisted on eating those fruits and vegetables over a period of 20 years were more likely to have better memory skills than those who seldom ate them. The study followed about 27,800 men in health care jobs over 20 years, and surveyed them on their diets and other health-related topics every four years. Toward the end of the study, the researchers started asking them questions about their memory. For example, “Do you have more trouble than usual remembering a short list of things, such as a shopping list?” or “Do you have more trouble than usual following a group conversation or a story in a TV program because of your memory?” “A growing number of ‘yes’ answers to such questions can mean their memory is going down,” the researchers said. The participants (参与者) were divided into five groups, based on how many servings (分量) of vegetables and fruits they got each day, from six servings in the healthiest group to just two servings. The six-serving eaters were 34 percent less likely to be forgetful. And the results were even better if the men happened to eat carotenoid (类胡萝卜素)-rich vegetables, such as carrots and pumpkins. Besides, those who drank orange juice often were 47 percent less likely to become forgetful, compared with those who drank orange juice less than once a month. “Our study provides further evidence that diet choices can be important to keep your brain healthy,” researchers said. 11．How long did the researchers follow the participants in the study? ________________________________________ 12．According to the study, what vegetables are good for people’s memory? ________________________________________ 13．According to Paragraph 4, what can it mean when a person’s memory is becoming worse? ________________________________________ 14．What do the researchers think the study can prove? ________________________________________ 15．Would you start drinking orange juice more often?
