Her head hit against the ice heavily. Everything went black. Up to that point, Sumathipala’s entire life had centred around her sport—her daily schedule, exercise routine, even her diet. She had hopes of making the 2018 Olympic team. The fall on the ice would change everything, including her direction. Sumathipala had a brain injury and it ended her skating career. Symptoms lasted for years. Her memory felt unclear at times. She’d find herself dizzy, sick, or exhausted. Sumathipala consulted doctors, so many that she “lost count.” But no one had answers. Sumathipala began to realize that there was so much unknown about the brain. She set out to find the answers herself, a path that would finally bring her to Harvard University, where she’d concentrate in the human brain. Throughout her four years, Surmathipala homed in on brain science. She worked with the McCarroll Lab at Harvard Medical School, helping develop a new method for sequencing synapses (神经突序列) in the brain, which are crucial for memory and learning. Even as an undergraduate, her colleagues were so struck by how mature (成熟的) her thinking already was about science that she quickly became a trusted and valued member of the lab. Also, Sumathipala competed with the Harvard Figure Skating Club all four years. She helped increase its membership and introduced new skaters to the sport she still loves. “I spent a long time struggling with my identity,” she said. “Growing up I was just a skater and then, when I got injured, I had to rebuild my identity. Then I was a scientist. Now, I identify as being both a skater and a scientist.” Reflecting on her years at Harvard, Sumathipala said one of the things she’s most grateful for is seeing how things have come full circle for her. 26．What do we know about Sumathipala’s injury? A．It stopped her skating finally. B．It led to her loss of eyesight. C．It changed her life direction. D．It was easily cured by doctors. 27．In what way did Sumathipala think she could find the answer to her disease? A．Turning to doctors. B．Go on practicing. C．Rebuilding her identity. D．Doing research on brain herself. 28．What does the underlined phrase “homed in on” in paragraph 4 probably mean? A．focused on B．returned to C．attended to D．stayed at 29．What made things come full circle for Sumathipala? A．Deep love for figure skating. B．Her determination to achieve life goals. C．The praise from her lab colleagues. D．Good relationship with new skaters. 【答案】26．C 27．D 28．A 29．B 【导语】本文是一篇记叙文。讲述了高中生玛丽莎·苏马蒂帕拉在与练习花样滑冰时与另一名滑冰运动员相撞，导致脑部受伤，记忆受损。后来，她自己专注于人脑研究，与哈佛医学院麦卡罗尔实验室合作，帮助开发了一种新方法，对大脑中对记忆和学习至关重要的突触进行排序。 26．细节理解题。根据“The fall on the ice would change everything, including her direction.”可知，苏马蒂帕拉的受伤改变了她的人生方向。故选C。 27．细节理解题。根据“Sumathipala began to realize that there was so much unknown about the brain. She set out to find the answers herself, a path that would finally bring her to Harvard University, where she’d concentrate in the human brain.”可知，她认为通过专注于人脑研究会帮助她找到答案。故选D。 28．词句猜测题。根据“She set out to find the answers herself, a path that would finally bring her to Harvard University, where she’d concentrate in the human brain. Throughout her four years, Surmathipala homed in on brain science.”可知，这里的homed in on与前一句的concentrate in“集中精力于、专注于”接近。A选项“专注于”符合题意。故选A。 29．推理判断题。根据倒数第二段“Growing up I was just a skater and then, when I got injured, I had to rebuild my identity. Then I was a scientist. Now, I identify as being both a skater and a scientist.”以及全文可知，这些事情在她身上实现了完整的循环，是因为她实现目标的决心：成长过程中，目标是入选2018年奥运会代表队；受伤后，目标是找到大脑问题的答案。故选B。 B Have you ever entered a room, only to forget what you went in there to do? Scientists think that the brain considers entering a doorway as a new scene, causing you to temporarily (暂时的) erase the short-term memory of why you went there. This is just one of the brain’s many unusual memory habits. And while forgetting can be discouraging, the human body can only work with a balance of erased and consolidated (已巩固的) memories. Your memory shapes who you are, provides meaning to your surroundings and allows you to form relationships. Your memory also serves as a survival tool. By learning what’s dangerous and remembering simple information such as where to find food, you’re better able to choose what will benefit you and what to avoid using your past experiences. When you learn new information, the brain forms new connections between nerve cells called neurons. This creates a map throughout the brain that makes stored information easier to find. The more you review, the stronger that connection becomes and the easier it is to remember. It might seem like the busier this neural map is, the more intelligent you will become. But just as a smart phone slows down when its storage reaches its limit, your brain is more efficient when it has less to process. It actively forgets information that isn’t reused by weakening the connections between neurons. Stopping unimportant information from becoming active memories prevents the brain becoming overwhelmed (不堪重负). In other examples, painful mind-consuming (精神消耗) memories of traumatic events can be blocked or rewritten to cause less pain. Forgetting these painful memories keeps the emotional stability needed in the brain for effective daily work. Forgetting also builds creativity. If memories were everlasting, our brains couldn’t develop new ways of thinking. Creativity provides humans the ability to explore new ways to problems. When you feel overwhelmed or stressed, your brain is less able to form new thinking patterns and returns to more rigid (死板的) habits and thought processes. This is sometimes the reason for experiencing a mental block during creative activities. Forgetting is often considered a weakness. But our memory is ever-developing and forgetting should be considered more of a superpower. When you erase the noise consuming your memory, more energy can be led into focusing and prioritizing (优先处理) the information needed to shape your sense of self and to stay mentally healthy. 30．What can we know about our memory? A．New environment prevents the short-term memory from being erased. B．Memory protects us from dangerous situations by recalling what to avoid. C．Erasing the short-term memory sometimes gives us a sense of inability. D．Our memory rather than forgetfulness can keep our bodies working well. 31．What does the phrase “traumatic events” in Paragraph 4 most probably mean? A．Exciting and dangerous activities. B．Mysterious and awful experiences. C．Tiring and uninteresting activities. D．Painful and worrying experiences. 32．Which of the following would the writer most probably agree with? A．Forgetting unimportant information can help the brain work effectively. B．Forgetting is the ability to form new thinking patterns to solve problems. C．We will experience mental block if we take part in more creative activities. D．The more information the brain processes, the more efficient it will become. 33．What is the writer’s main purpose in writing this passage? A．To show how forgetting benefits us. B．To encourage us to improve our memory. C．To explain how we learn new information. D．To advise us to review regularly. 【答案】30．B 31．D 32．A 33．A 【导语】本文主要说明了遗忘在大脑运作中的重要作用。文章指出记忆能够帮助我们识别危险、积累经验，而适当的遗忘既能缓解大脑负担，也能保持情绪稳定，并促进创造性思维的发展，最后强调遗忘应被视为一种有益的“超能力”。 30．细节理解题。根据“Your memory also serves as a survival tool.…you’re better able to choose what will benefit you and what to avoid using your past experiences.”可知，记忆在回忆危险并让人知道应当避免什么方面起到保护作用。选项B“记忆通过回想该避免什么来保护我们远离危险”与文意相符。故选B。 31．词义猜测题。根据“painful mind-consuming (精神消耗) memories of traumatic events can be blocked or rewritten to cause less pain.”可知，创伤事件的痛苦记忆可以被屏蔽或重写，以减少痛苦。这里的“traumatic events”指让人感到痛苦和担忧的经历。故选D。 32．推理判断题。根据“It actively forgets information that isn’t reused by weakening the connections between neurons. Stopping unimportant information from becoming active memories prevents the brain becoming overwhelmed (不堪重负).”可推断，遗忘不重要的信息有助于大脑的正常运作和提高效率。选项A“遗忘不重要的信息能帮助大脑更有效地工作”符合作者观点。故选A。 33．主旨大意题。通读全文可知，作者通过多方面阐述遗忘对人类思维、情绪和创造力的积极作用，从而说明“遗忘是种益处”，A项“展示遗忘如何给我们带来好处”与文章主旨吻合。故选A。 C ①Having trouble getting out of bed for school on Monday mornings? This year`s World Sleep Day on March 21 has brought attention to the problem of teenagers not getting enough sleep. ②Many teenagers feel sleepy during the day because of homework, after-school activities, and wanting to use electronic devices. For example, in the US,77.3 percent of high school students are sleep-deprived (缺乏睡眠的), said USA Facts. ③Quality sleep is important for everyone, but it is especially important for teenagers. They need nine to 10 hours of sleep each day-more than adults, according to the US National Institute of Health. This is because adolescence (青春期) is a time of deep mental, physical, social and emotional (情绪的) growth. ④For students, sleep helps them do better in school. It improves focus (专注), strengthens memory and helps with thinking skills, Harvard Health pointed out. ⑤Sleep also helps with creativity. Scientists at Loughborough University in the UK studied this in the late 20th century. They compared creative test scores between people who didn’t sleep well and those who slept normally. The sleep-deprived group got lower scores on the Torrance Tests of Creative Thinking. They repeated the same mistakes and had trouble coming up with new ideas. ⑥More recently, in 2023, a team led by Kathleen Esfahany at the US Massachusetts Institute of Technology (MIT) found that sleep onset (睡眠开始), a special stage (阶段) at the beginning of sleep, is especially good for creativity. This is the time when we are just falling asleep. When people were asked to dream about a certain topic during this stage, they did better on creative tasks about that topic after waking up. 34．What can we infer from the MIT study mentioned in the passage? A．The sleep onset stage is critical for creative thinking. B．Creativity is unrelated to sleep quality. C．Dreaming during deep sleep is most beneficial for creativity. D．People who sleep less are more likely to have original ideas. 35．What’s the meaning of ‘strengthens’ in paragraph 4? A．to hold something B．to make something stronger C．to become strange D．to remember something 36．What might happen if a teenager gets enough sleep? A．They would have difficulty focusing in class. B．Their memory and thinking skills would improve. C．They would perform worse on creative tasks. D．They would be more likely to change schools. 37．What is the main idea of the passage? A．Solutions to improve teenagers’ sleep habits. B．How electronic devices affect teenagers’ sleep quality. C．A comparison of sleep needs between adults and teenagers. D．The importance of sleep for teenagers and its impact on their development. 【答案】34．A 35．B 36．B 37．D 【导语】本文是一篇说明文，主要讲述了睡眠对青少年的重要性及其对学习、记忆、思维能力和创造力的积极影响。 34．推理判断题。根据文章第6段“a team led by Kathleen Esfahany… found that sleep onset… is especially good for creativity”可知，睡眠开始阶段对创造性思维至关重要。故选A。 35．词句猜测题。根据文章第4段“strengthens memory”可知，结合语境是“增强记忆力”，“strengthens”意为“使某物更强”。故选B。 36．细节理解题。根据文章第4段“It improves focus, strengthens memory and helps with thinking skills”可知，充足睡眠能提升青少年的记忆和思维能力。故选B。 37．主旨大意题。全文围绕睡眠对青少年的重要性展开，包括其生理、心理和认知发展的影响。选项D全面概括了这一主题。故选D。 D Do you think you have a good memory (记忆) ? It is difficult to say exactly what memory is. Even scientists who have been studying memory for many years say that they are still trying to find out what it is. We do know that memory is not just one thing stored (存储) somewhere in the brain (大脑). Memory is made up of small pieces of information stored all over the brain. The human brain is very small and light. But it needs about 20% of the oxygen (氧气) that our body takes in. We can’t think well if our brain isn’t getting enough oxygen, so always make sure there is enough oxygen in the air when you need to learn or remember something! Why do you forget things sometimes? The main reason for forgetting something is that you did not learn it well enough in the beginning. For example, if you meet some new people and right away forget their names, it is because you didn’t record (记录) the names when you heard them. No one can remember everything, but everyone can learn how to improve their memory. Here are some ways: ●When you want to remember something, tell a friend about it. This way the new information becomes more memorable. Later on, think about the conversation with your friend. It will help you remember the information. ●Don’t over-train your brain. When you’ve remembered a list of new vocabulary, stop studying. It’s better to study a lot of material (材料) for a short time than a small part of material for a lot of time! But remember: you do have to practice your new vocabulary as soon as possible! ●If you have to remember something big, break it down into smaller parts. It’s easier to remember 198756430387 if you break it into four smaller bits: 198-756-430-387. ●If you want to remember a piece of information, and you can’t, don’t get angry. Relax when you study! Try to enjoy yourself. You are learning new things every minute. You will remember better if you are happy and relaxed. In short, none of (没有一个) the ways can make your memory 100% perfect, but all of them are helpful. 38．Which of the following sentences is true according to the passage? A．We can make our memory 100% perfect. B．We can break the big information into big parts. C．We should spend a lot of time studying a small part of material. D．We’ll forget things if we don’t learn them well in the beginning. 39．According to the passage, the writer probably agrees with ________. A．sharing new information with friends B．remembering long numbers by writing C．learning at least 100 new words at a time D．getting angry when you can’t remember any information 40．What does the writer mainly talk about in the passage? A．What the human brain is and where memory is stored. B．When we think well and how we remember everything. C．Why we forget something and how we improve our memory. D．What memory is made up of and who can have a good memory. 【答案】38．D 39．A 40．C 【导语】本文是一篇说明文，主要介绍了记忆的存储位置、遗忘的原因以及提高记忆力的方法。 38．细节理解题。根据第三段中“Why do you forget things sometimes?

This way the new information becomes more memorable.”可知，作者认为当你想记住某件事时，就把它告诉朋友，这样的话新信息就更容易被记住。故选A。 40．主旨大意题。通读全文可知，本文主要介绍了记忆的存储位置、遗忘的原因以及提高记忆力的方法，所以C选项“为什么容易忘记事情以及怎样提高记忆力”与文章主旨相符。故选C。 第二节 阅读填空（本题共5小题，每小题1分，共5分） 根据材料内容，从下面五个选项中选出能填入文中空缺处的最佳选项，使短文意思通顺、内容完整。 Smart Study Habits for Busy Students You are always busy with many school subjects and don’t have enough time to finish all the homework. How can you find time to study English effectively (高效地)? The secret is in smart study habits. Don’t study for quite a long time. Your brain gets tired and stops remembering well. 41 For example, study for 40 minutes every day instead of two hours on Sunday. It’s a good way to refresh your brain to take a break after studying for 40 minutes. Use a notebook specifically for English. You’d better read an English passage every day and write down five to fifteen new words each time. Don’t just write the word and its translation. 42 This helps you remember how to use it correctly. 43 Before you learn new words, always spend five minutes reviewing the words you learned yesterday and last week. Our brains forget quickly. 44 Finally, set a clear goal for each study session. Don’t just say, “I will study English.” Say, “Today I will learn how to use the past tense (过去式) to make ten sentences.” 45 . With these smart habits, you can learn more English in less time and still have time for your other subjects and hobbies! A．Review is magic! B．Write a full sentence using the word. C．Instead, try studying for shorter periods more often. D．A clear goal helps you focus and feel successful when you achieve it. E．So we need to see information many times to remember it forever. 【答案】41．C 42．B 43．A 44．E 45．D 【导语】本文是一篇说明文，主要介绍了忙碌学生如何通过高效的学习习惯来学习英语。文章提出了分段学习、使用笔记本、复习、设定明确目标等方法。 41．根据“Don’t study for a quite long time. Your brain gets tired and stops remembering well.”（不要长时间学习，大脑会疲劳并停止有效记忆）可知，此处应建议缩短学习时间并增加频率。选项C“相反，尝试更频繁地进行短时间学习”符合语境。故选C。 42．根据“Don’t just write the word and its translation.”（不要只写单词和翻译）可知，此处应补充如何更有效地记录单词。选项B“用这个单词写一个完整的句子”符合语境，因为后文提到“This helps you remember how to use it correctly.”。故选B。 43．根据“Before you learn new words, always spend five minutes reviewing the words you learned yesterday and last week.”（在学习新单词前，花五分钟复习昨天和上周学过的单词）可知，此处强调复习的重要性。选项A“复习是魔法！”符合语境。故选A。 44．根据“Our brains forget quickly.”（我们的大脑遗忘很快）可知，此处应补充说明需要反复复习的原因。选项E“因此我们需要多次接触信息才能永久记住”符合语境。故选E。 45．根据“set a clear goal for each study session...‘Today I will learn how to use the past tense to make ten sentences.’”（为每次学习设定明确目标……“今天我要学习用过去式造十个句子”）可知，此处应说明目标的作用。选项D“明确的目标帮助你集中注意力，并在达成时感到成功”符合语境。故选D。 第II卷（非选择题） 四、写作（共三节，满分30分） 第一节．语篇填词（本题共5小题，每小题1分，共5分） 根据下列语篇以及所给单词的首字母写出所缺单词。在填写答题卡时，要求写出完整单词，每空只写一词。 If you have a good memory, you won’t easily forget what you have seen before.

Her head hit against the ice heavily. Everything went black. Up to that point, Sumathipala’s entire life had centred around her sport—her daily schedule, exercise routine, even her diet. She had hopes of making the 2018 Olympic team. The fall on the ice would change everything, including her direction. Sumathipala had a brain injury and it ended her skating career. Symptoms lasted for years. Her memory felt unclear at times. She’d find herself dizzy, sick, or exhausted. Sumathipala consulted doctors, so many that she “lost count.” But no one had answers. Sumathipala began to realize that there was so much unknown about the brain. She set out to find the answers herself, a path that would finally bring her to Harvard University, where she’d concentrate in the human brain. Throughout her four years, Surmathipala homed in on brain science. She worked with the McCarroll Lab at Harvard Medical School, helping develop a new method for sequencing synapses (神经突序列) in the brain, which are crucial for memory and learning. Even as an undergraduate, her colleagues were so struck by how mature (成熟的) her thinking already was about science that she quickly became a trusted and valued member of the lab. Also, Sumathipala competed with the Harvard Figure Skating Club all four years. She helped increase its membership and introduced new skaters to the sport she still loves. “I spent a long time struggling with my identity,” she said. “Growing up I was just a skater and then, when I got injured, I had to rebuild my identity. Then I was a scientist. Now, I identify as being both a skater and a scientist.” Reflecting on her years at Harvard, Sumathipala said one of the things she’s most grateful for is seeing how things have come full circle for her. 26．What do we know about Sumathipala’s injury? A．It stopped her skating finally. B．It led to her loss of eyesight. C．It changed her life direction. D．It was easily cured by doctors. 27．In what way did Sumathipala think she could find the answer to her disease? A．Turning to doctors. B．Go on practicing. C．Rebuilding her identity. D．Doing research on brain herself. 28．What does the underlined phrase “homed in on” in paragraph 4 probably mean? A．focused on B．returned to C．attended to D．stayed at 29．What made things come full circle for Sumathipala? A．Deep love for figure skating. B．Her determination to achieve life goals. C．The praise from her lab colleagues. D．Good relationship with new skaters. B Have you ever entered a room, only to forget what you went in there to do? Scientists think that the brain considers entering a doorway as a new scene, causing you to temporarily (暂时的) erase the short-term memory of why you went there. This is just one of the brain’s many unusual memory habits. And while forgetting can be discouraging, the human body can only work with a balance of erased and consolidated (已巩固的) memories. Your memory shapes who you are, provides meaning to your surroundings and allows you to form relationships. Your memory also serves as a survival tool. By learning what’s dangerous and remembering simple information such as where to find food, you’re better able to choose what will benefit you and what to avoid using your past experiences. When you learn new information, the brain forms new connections between nerve cells called neurons. This creates a map throughout the brain that makes stored information easier to find. The more you review, the stronger that connection becomes and the easier it is to remember. It might seem like the busier this neural map is, the more intelligent you will become. But just as a smart phone slows down when its storage reaches its limit, your brain is more efficient when it has less to process. It actively forgets information that isn’t reused by weakening the connections between neurons. Stopping unimportant information from becoming active memories prevents the brain becoming overwhelmed (不堪重负). In other examples, painful mind-consuming (精神消耗) memories of traumatic events can be blocked or rewritten to cause less pain. Forgetting these painful memories keeps the emotional stability needed in the brain for effective daily work. Forgetting also builds creativity. If memories were everlasting, our brains couldn’t develop new ways of thinking. Creativity provides humans the ability to explore new ways to problems. When you feel overwhelmed or stressed, your brain is less able to form new thinking patterns and returns to more rigid (死板的) habits and thought processes. This is sometimes the reason for experiencing a mental block during creative activities. Forgetting is often considered a weakness. But our memory is ever-developing and forgetting should be considered more of a superpower. When you erase the noise consuming your memory, more energy can be led into focusing and prioritizing (优先处理) the information needed to shape your sense of self and to stay mentally healthy. 30．What can we know about our memory? A．New environment prevents the short-term memory from being erased. B．Memory protects us from dangerous situations by recalling what to avoid. C．Erasing the short-term memory sometimes gives us a sense of inability. D．Our memory rather than forgetfulness can keep our bodies working well. 31．What does the phrase “traumatic events” in Paragraph 4 most probably mean? A．Exciting and dangerous activities. B．Mysterious and awful experiences. C．Tiring and uninteresting activities. D．Painful and worrying experiences. 32．Which of the following would the writer most probably agree with? A．Forgetting unimportant information can help the brain work effectively. B．Forgetting is the ability to form new thinking patterns to solve problems. C．We will experience mental block if we take part in more creative activities. D．The more information the brain processes, the more efficient it will become. 33．What is the writer’s main purpose in writing this passage? A．To show how forgetting benefits us. B．To encourage us to improve our memory. C．To explain how we learn new information. D．To advise us to review regularly. C ①Having trouble getting out of bed for school on Monday mornings? This year`s World Sleep Day on March 21 has brought attention to the problem of teenagers not getting enough sleep. ②Many teenagers feel sleepy during the day because of homework, after-school activities, and wanting to use electronic devices. For example, in the US,77.3 percent of high school students are sleep-deprived (缺乏睡眠的), said USA Facts. ③Quality sleep is important for everyone, but it is especially important for teenagers. They need nine to 10 hours of sleep each day-more than adults, according to the US National Institute of Health. This is because adolescence (青春期) is a time of deep mental, physical, social and emotional (情绪的) growth. ④For students, sleep helps them do better in school. It improves focus (专注), strengthens memory and helps with thinking skills, Harvard Health pointed out. ⑤Sleep also helps with creativity. Scientists at Loughborough University in the UK studied this in the late 20th century. They compared creative test scores between people who didn’t sleep well and those who slept normally. The sleep-deprived group got lower scores on the Torrance Tests of Creative Thinking. They repeated the same mistakes and had trouble coming up with new ideas. ⑥More recently, in 2023, a team led by Kathleen Esfahany at the US Massachusetts Institute of Technology (MIT) found that sleep onset (睡眠开始), a special stage (阶段) at the beginning of sleep, is especially good for creativity. This is the time when we are just falling asleep. When people were asked to dream about a certain topic during this stage, they did better on creative tasks about that topic after waking up. 34．What can we infer from the MIT study mentioned in the passage? A．The sleep onset stage is critical for creative thinking. B．Creativity is unrelated to sleep quality. C．Dreaming during deep sleep is most beneficial for creativity. D．People who sleep less are more likely to have original ideas. 35．What’s the meaning of ‘strengthens’ in paragraph 4? A．to hold something B．to make something stronger C．to become strange D．to remember something 36．What might happen if a teenager gets enough sleep? A．They would have difficulty focusing in class. B．Their memory and thinking skills would improve. C．They would perform worse on creative tasks. D．They would be more likely to change schools. 37．What is the main idea of the passage? A．Solutions to improve teenagers’ sleep habits. B．How electronic devices affect teenagers’ sleep quality. C．A comparison of sleep needs between adults and teenagers. D．The importance of sleep for teenagers and its impact on their development. D Do you think you have a good memory (记忆) ? It is difficult to say exactly what memory is. Even scientists who have been studying memory for many years say that they are still trying to find out what it is. We do know that memory is not just one thing stored (存储) somewhere in the brain (大脑). Memory is made up of small pieces of information stored all over the brain. The human brain is very small and light. But it needs about 20% of the oxygen (氧气) that our body takes in. We can’t think well if our brain isn’t getting enough oxygen, so always make sure there is enough oxygen in the air when you need to learn or remember something! Why do you forget things sometimes? The main reason for forgetting something is that you did not learn it well enough in the beginning. For example, if you meet some new people and right away forget their names, it is because you didn’t record (记录) the names when you heard them. No one can remember everything, but everyone can learn how to improve their memory. Here are some ways: ●When you want to remember something, tell a friend about it. This way the new information becomes more memorable. Later on, think about the conversation with your friend. It will help you remember the information. ●Don’t over-train your brain. When you’ve remembered a list of new vocabulary, stop studying. It’s better to study a lot of material (材料) for a short time than a small part of material for a lot of time! But remember: you do have to practice your new vocabulary as soon as possible! ●If you have to remember something big, break it down into smaller parts. It’s easier to remember 198756430387 if you break it into four smaller bits: 198-756-430-387. ●If you want to remember a piece of information, and you can’t, don’t get angry. Relax when you study! Try to enjoy yourself. You are learning new things every minute. You will remember better if you are happy and relaxed. In short, none of (没有一个) the ways can make your memory 100% perfect, but all of them are helpful. 38．Which of the following sentences is true according to the passage? A．We can make our memory 100% perfect. B．We can break the big information into big parts. C．We should spend a lot of time studying a small part of material. D．We’ll forget things if we don’t learn them well in the beginning. 39．According to the passage, the writer probably agrees with ________. A．sharing new information with friends B．remembering long numbers by writing C．learning at least 100 new words at a time D．getting angry when you can’t remember any information 40．What does the writer mainly talk about in the passage? A．What the human brain is and where memory is stored. B．When we think well and how we remember everything. C．Why we forget something and how we improve our memory. D．What memory is made up of and who can have a good memory. 第二节 阅读填空（本题共5小题，每小题1分，共5分） 根据材料内容，从下面五个选项中选出能填入文中空缺处的最佳选项，使短文意思通顺、内容完整。 Smart Study Habits for Busy Students You are always busy with many school subjects and don’t have enough time to finish all the homework.

Her head hit against the ice heavily. Everything went black. Up to that point, Sumathipala’s entire life had centred around her sport—her daily schedule, exercise routine, even her diet. She had hopes of making the 2018 Olympic team. The fall on the ice would change everything, including her direction. Sumathipala had a brain injury and it ended her skating career. Symptoms lasted for years. Her memory felt unclear at times. She’d find herself dizzy, sick, or exhausted. Sumathipala consulted doctors, so many that she “lost count.” But no one had answers. Sumathipala began to realize that there was so much unknown about the brain. She set out to find the answers herself, a path that would finally bring her to Harvard University, where she’d concentrate in the human brain. Throughout her four years, Surmathipala homed in on brain science. She worked with the McCarroll Lab at Harvard Medical School, helping develop a new method for sequencing synapses (神经突序列) in the brain, which are crucial for memory and learning. Even as an undergraduate, her colleagues were so struck by how mature (成熟的) her thinking already was about science that she quickly became a trusted and valued member of the lab. Also, Sumathipala competed with the Harvard Figure Skating Club all four years. She helped increase its membership and introduced new skaters to the sport she still loves. “I spent a long time struggling with my identity,” she said. “Growing up I was just a skater and then, when I got injured, I had to rebuild my identity. Then I was a scientist. Now, I identify as being both a skater and a scientist.” Reflecting on her years at Harvard, Sumathipala said one of the things she’s most grateful for is seeing how things have come full circle for her. 26．What do we know about Sumathipala’s injury? A．It stopped her skating finally. B．It led to her loss of eyesight. C．It changed her life direction. D．It was easily cured by doctors. 27．In what way did Sumathipala think she could find the answer to her disease? A．Turning to doctors. B．Go on practicing. C．Rebuilding her identity. D．Doing research on brain herself. 28．What does the underlined phrase “homed in on” in paragraph 4 probably mean? A．focused on B．returned to C．attended to D．stayed at 29．What made things come full circle for Sumathipala? A．Deep love for figure skating. B．Her determination to achieve life goals. C．The praise from her lab colleagues. D．Good relationship with new skaters. B Have you ever entered a room, only to forget what you went in there to do? Scientists think that the brain considers entering a doorway as a new scene, causing you to temporarily (暂时的) erase the short-term memory of why you went there. This is just one of the brain’s many unusual memory habits. And while forgetting can be discouraging, the human body can only work with a balance of erased and consolidated (已巩固的) memories. Your memory shapes who you are, provides meaning to your surroundings and allows you to form relationships. Your memory also serves as a survival tool. By learning what’s dangerous and remembering simple information such as where to find food, you’re better able to choose what will benefit you and what to avoid using your past experiences. When you learn new information, the brain forms new connections between nerve cells called neurons. This creates a map throughout the brain that makes stored information easier to find. The more you review, the stronger that connection becomes and the easier it is to remember. It might seem like the busier this neural map is, the more intelligent you will become. But just as a smart phone slows down when its storage reaches its limit, your brain is more efficient when it has less to process. It actively forgets information that isn’t reused by weakening the connections between neurons. Stopping unimportant information from becoming active memories prevents the brain becoming overwhelmed (不堪重负). In other examples, painful mind-consuming (精神消耗) memories of traumatic events can be blocked or rewritten to cause less pain. Forgetting these painful memories keeps the emotional stability needed in the brain for effective daily work. Forgetting also builds creativity. If memories were everlasting, our brains couldn’t develop new ways of thinking. Creativity provides humans the ability to explore new ways to problems. When you feel overwhelmed or stressed, your brain is less able to form new thinking patterns and returns to more rigid (死板的) habits and thought processes. This is sometimes the reason for experiencing a mental block during creative activities. Forgetting is often considered a weakness. But our memory is ever-developing and forgetting should be considered more of a superpower. When you erase the noise consuming your memory, more energy can be led into focusing and prioritizing (优先处理) the information needed to shape your sense of self and to stay mentally healthy. 30．What can we know about our memory? A．New environment prevents the short-term memory from being erased. B．Memory protects us from dangerous situations by recalling what to avoid. C．Erasing the short-term memory sometimes gives us a sense of inability. D．Our memory rather than forgetfulness can keep our bodies working well. 31．What does the phrase “traumatic events” in Paragraph 4 most probably mean? A．Exciting and dangerous activities. B．Mysterious and awful experiences. C．Tiring and uninteresting activities. D．Painful and worrying experiences. 32．Which of the following would the writer most probably agree with? A．Forgetting unimportant information can help the brain work effectively. B．Forgetting is the ability to form new thinking patterns to solve problems. C．We will experience mental block if we take part in more creative activities. D．The more information the brain processes, the more efficient it will become. 33．What is the writer’s main purpose in writing this passage? A．To show how forgetting benefits us. B．To encourage us to improve our memory. C．To explain how we learn new information. D．To advise us to review regularly. C ①Having trouble getting out of bed for school on Monday mornings? This year`s World Sleep Day on March 21 has brought attention to the problem of teenagers not getting enough sleep. ②Many teenagers feel sleepy during the day because of homework, after-school activities, and wanting to use electronic devices. For example, in the US,77.3 percent of high school students are sleep-deprived (缺乏睡眠的), said USA Facts. ③Quality sleep is important for everyone, but it is especially important for teenagers. They need nine to 10 hours of sleep each day-more than adults, according to the US National Institute of Health. This is because adolescence (青春期) is a time of deep mental, physical, social and emotional (情绪的) growth. ④For students, sleep helps them do better in school. It improves focus (专注), strengthens memory and helps with thinking skills, Harvard Health pointed out. ⑤Sleep also helps with creativity. Scientists at Loughborough University in the UK studied this in the late 20th century. They compared creative test scores between people who didn’t sleep well and those who slept normally. The sleep-deprived group got lower scores on the Torrance Tests of Creative Thinking. They repeated the same mistakes and had trouble coming up with new ideas. ⑥More recently, in 2023, a team led by Kathleen Esfahany at the US Massachusetts Institute of Technology (MIT) found that sleep onset (睡眠开始), a special stage (阶段) at the beginning of sleep, is especially good for creativity. This is the time when we are just falling asleep. When people were asked to dream about a certain topic during this stage, they did better on creative tasks about that topic after waking up. 34．What can we infer from the MIT study mentioned in the passage? A．The sleep onset stage is critical for creative thinking. B．Creativity is unrelated to sleep quality. C．Dreaming during deep sleep is most beneficial for creativity. D．People who sleep less are more likely to have original ideas. 35．What’s the meaning of ‘strengthens’ in paragraph 4? A．to hold something B．to make something stronger C．to become strange D．to remember something 36．What might happen if a teenager gets enough sleep? A．They would have difficulty focusing in class. B．Their memory and thinking skills would improve. C．They would perform worse on creative tasks. D．They would be more likely to change schools. 37．What is the main idea of the passage? A．Solutions to improve teenagers’ sleep habits. B．How electronic devices affect teenagers’ sleep quality. C．A comparison of sleep needs between adults and teenagers. D．The importance of sleep for teenagers and its impact on their development. D Do you think you have a good memory (记忆) ? It is difficult to say exactly what memory is. Even scientists who have been studying memory for many years say that they are still trying to find out what it is. We do know that memory is not just one thing stored (存储) somewhere in the brain (大脑). Memory is made up of small pieces of information stored all over the brain. The human brain is very small and light. But it needs about 20% of the oxygen (氧气) that our body takes in. We can’t think well if our brain isn’t getting enough oxygen, so always make sure there is enough oxygen in the air when you need to learn or remember something! Why do you forget things sometimes? The main reason for forgetting something is that you did not learn it well enough in the beginning. For example, if you meet some new people and right away forget their names, it is because you didn’t record (记录) the names when you heard them. No one can remember everything, but everyone can learn how to improve their memory. Here are some ways: ●When you want to remember something, tell a friend about it. This way the new information becomes more memorable. Later on, think about the conversation with your friend. It will help you remember the information. ●Don’t over-train your brain. When you’ve remembered a list of new vocabulary, stop studying. It’s better to study a lot of material (材料) for a short time than a small part of material for a lot of time! But remember: you do have to practice your new vocabulary as soon as possible! ●If you have to remember something big, break it down into smaller parts. It’s easier to remember 198756430387 if you break it into four smaller bits: 198-756-430-387. ●If you want to remember a piece of information, and you can’t, don’t get angry. Relax when you study! Try to enjoy yourself. You are learning new things every minute. You will remember better if you are happy and relaxed. In short, none of (没有一个) the ways can make your memory 100% perfect, but all of them are helpful. 38．Which of the following sentences is true according to the passage? A．We can make our memory 100% perfect. B．We can break the big information into big parts. C．We should spend a lot of time studying a small part of material. D．We’ll forget things if we don’t learn them well in the beginning. 39．According to the passage, the writer probably agrees with ________. A．sharing new information with friends B．remembering long numbers by writing C．learning at least 100 new words at a time D．getting angry when you can’t remember any information 40．What does the writer mainly talk about in the passage? A．What the human brain is and where memory is stored. B．When we think well and how we remember everything. C．Why we forget something and how we improve our memory. D．What memory is made up of and who can have a good memory. 第二节 阅读填空（本题共5小题，每小题1分，共5分） 根据材料内容，从下面五个选项中选出能填入文中空缺处的最佳选项，使短文意思通顺、内容完整。 Smart Study Habits for Busy Students You are always busy with many school subjects and don’t have enough time to finish all the homework. How can you find time to study English effectively (高效地)? The secret is in smart study habits. Don’t study for quite a long time. Your brain gets tired and stops remembering well. 41 For example, study for 40 minutes every day instead of two hours on Sunday. It’s a good way to refresh your brain to take a break after studying for 40 minutes. Use a notebook specifically for English. You’d better read an English passage every day and write down five to fifteen new words each time. Don’t just write the word and its translation. 42 This helps you remember how to use it correctly. 43 Before you learn new words, always spend five minutes reviewing the words you learned yesterday and last week. Our brains forget quickly. 44 Finally, set a clear goal for each study session. Don’t just say, “I will study English.” Say, “Today I will learn how to use the past tense (过去式) to make ten sentences.” 45 . With these smart habits, you can learn more English in less time and still have time for your other subjects and hobbies! A．Review is magic! B．Write a full sentence using the word. C．Instead, try studying for shorter periods more often. D．A clear goal helps you focus and feel successful when you achieve it. E．So we need to see information many times to remember it forever. 第II卷（非选择题） 四、写作（共三节，满分30分） 第一节．语篇填词（本题共5小题，每小题1分，共5分） 根据下列语篇以及所给单词的首字母写出所缺单词。在填写答题卡时，要求写出完整单词，每空只写一词。 If you have a good memory, you won’t easily forget what you have seen before.
