Without enough rest, new information may not 19 your long-term memory. Another useful method is to 20 new information with something you already know. For example, if you learn a new word, try to 21 it with a picture or a story. Stress is another factor that 22 memory. When you are stressed, your brain cannot work at its best.

What’s wrong? Lily: 26 I missed many things Mum asked me to buy. Tom: That’s terrible. 27 Lily: I stay up late every day and have too much stress. Tom: No wonder. 28 Lily: I attended Professor Green’s lecture yesterday. He shared many memory skills. Tom: Great! What’s his most useful tip? Lily: Pay attention to the details of words. 29 Tom: Any other good way? Lily: 30 It’s like building a chain in our brain. A．Why do you forget things so often recently?

E．You should write down important things and take notes. F．It helps us tell similar words apart and not mix them up. 四、阅读理解。(本大题共10小题，每小题2分，共20分) 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. 31．What did Group A do after reviewing words? A．Played games. B．Went to sleep. C．Watched TV. D．Ran outside. 32．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 33．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. 34．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. 35．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. Grandmother’s Lost Memories Rick’s grandma is over seventy years old. These days, her memory becomes much worse. Last weekend, Rick visited her home and found some strange changes. She kept calling Rick Johnny, which is Rick’s father’s name. When Rick wanted to eat cookies, she told him those snacks were saved for her grandson, not realizing Rick was exactly that grandson. Rick felt really sad and worried about her condition. He talked with his classmate Chen Jie, whose grandpa also has memory problems. Chen told Rick that old people’s memory usually falls little by little as they grow older. His grandpa once forgot the way to their park, so Chen takes him there every weekend. Chen shared a useful idea with Rick: do not only focus on the things the old lady forgets. We should keep in mind all the warm happy memories she still holds. Rick’s grandma still remembers he loves cookies deeply, and this warm memory is very valuable. The two boys discussed what they could do for the elderly with poor memory. They decided to look back on happy family moments together, such as picnics and old opera shows. They planned to take many new photos and make a family photo album for Rick’s grandma. Looking at pictures can help her recall more warm stories from the past. Rick finally understood sadness cannot solve the problem. Instead of feeling upset, he should stay with his grandma and create more new sweet memories with her. 36．Who is Johnny according to the text? A．Rick’s grandfather. B．Rick’s father. C．Chen Jie’s grandpa. D．Rick’s little brother. 37．What trouble does Chen Jie’s grandpa have? A．He forgets the way to the park. B．He cannot remember any food. C．He loses his wallet every day. D．He cannot speak complete sentences. 38．What suggestion did Chen give to Rick? A．Send his grandma to hospital right away. B．Pay more attention to the happy memories she still has. C．Stop visiting his grandma to avoid sadness. D．Teach his grandma new memory skills every day. 39．What plan did the two boys make for Rick’s grandma? A．Buy lots of cookies for her every week. B．Make a family photo album with new photos. C．Take her to watch operas alone every day. D．Move the grandma to live with Rick’s family. 40．What can we learn from Rick’s story? A．Old people will lose all memories completely. B．We should value the warm memories the elderly still keep. C．Sadness can help old people get back their memory. D．Photo albums cannot help recall past moments. 五、单词拼写。(本大题共10小题，每小题1分，共10分) 41．My ________ (孙子) likes playing outdoors. 42．We will bring some fruit and sandwiches to have a nice ________ (野餐) in the park this Saturday. 43．We need to ________ (组织) new information in our brain. 44．This medicine is ________ (有效的) for your wound. 45．He has been feeling a lot of ________ (焦虑) over his new job. 46．There has been an ________ (增长) in the number of students joining the reading club. 47．We need a ________ (稳定的) learning environment. 48．Don’t ________ (混淆) the two difficult grammar rules. 49．A wave of ________ (悲伤) came over her. 50．My father often told me not to care only about ________ (短期的) results. 六、完成句子(本大题共5小题，每小题2分，共10分) 51．互联网使得我们分享学习资源变得便捷。   The Internet ________ ________ ________ for us to share learning resources. 52．毕竟，这本笔记是她和妹妹共同整理的。   ________ ________, she organized this notebook together with her sister. 53．她在旅行中经历了美好的时刻。   She ________ ________ ________ during the trip. 54．如果你经常写字，你的铅笔就会很容易磨损。   If you often write, your pencil will ________ ________ easily. 55．对不起，但是李女士，你能重复一遍你说的话吗？   I’m ________, but would you repeat ________ you said, Ms. Li? 七、完成句子。(本大题共5小题，每小题2分，共10分) 56．He has a good memory.

Over 1,000 scientists, educators, and technology experts from 42 countries gathered 61 (discuss) the latest discoveries about human memory. Dr. Li Ming, a neuroscientist from Tsinghua University, explained 62 memory works at the cellular level. “Every time you learn something new, your brain forms new connections between neurons. This process 63 (call) synaptic plasticity. It is the biological basis of all learning and memory.” One of the most exciting presentations came from a team at the University of Tokyo. They demonstrated 64 a new brain stimulation technique can improve memory performance by 20% in healthy adults. The technique uses non-invasive electrical stimulation to enhance the activity of the hippocampus. 65 the researchers said, the results are “promising but still experimental.” It is important 66 people to understand that memory is not fixed. “Your memory ability is not determined at birth,” said Dr. Maria Gonzalez from the Max Planck Institute. “ 67 you train your memory regularly, you can see significant improvements at any age.” The summit also addressed the growing concern about digital dependence. Many participants discussed 68 students are relying too much on smartphones and search engines. They concluded 69 learners should still develop strong foundational memory skills. “Technology should be a tool, not a substitute,” Dr. Li added. The final session focused on the future of memory research. Scientists believe within ten years, we will have a much deeper understanding of how the brain stores and retrieves information. This knowledge could lead to new treatments for memory disorders and better learning strategies for everyone. It is wise 70 young learners to start using science-based memory techniques today. With consistent practice, every student can unlock more of their brain’s potential. 八、书面表达(共10分) 71．良好的记忆力对学习至关重要，请你以“How to Improve Our Memory”为题，写一篇英语短文。 内容包括： 1. 良好记忆力的重要性； 2. 提升记忆力的3-4种方法(锻炼、充足睡眠、及时复习、趣味记忆等)； 3. 你的感悟。 要求：80-100词，语法正确，语句通顺，卷面整洁。 ___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 试题 第3页（共8页） 试题 第4页（共8页） 试题 第1页（共8页） 试题 第2页（共8页） 学科网（北京）股份有限公司 $ 2026-2027学年九年级上册英语单元自测 Unit 4 Our Memory·能力提升 学校:___________班级：___________姓名：___________分数：___________ （时间：90分钟，满分：100分） 一、单项选择。(本大题共15小题，每小题1分，共15分) 1．Nobody knows ________ the memory mystery completely.

If you forget one, you may lose the whole thing. A．connects to B．mixes up C．runs out of D．reacts to 【答案】A 【详解】句意：记忆就像一条链条；一部分连接到另一部分。如果你忘记了一个，你可能会失去整个东西。 connects to连接；mixes up混淆；runs out of用完；reacts to对……作出反应。根据“Memory is like a chain”可知，链条的特点是环环相扣，即一部分与另一部分相连。connects to意为“连接到”，符合语境；应填connects to。 5．If you feel ________ while studying, you should take a break and listen to some light music. A．confident B．relaxed C．stressed D．happy 【答案】C 【详解】句意：如果你在学习时感到有压力，你应该休息一下，听些轻音乐。 confident自信的；relaxed放松的；stressed有压力的；happy开心的。根据“you should take a break and listen to some light music”可知，需要放松是因为感到压力，故用stressed。 6．Paying attention to every detail is the key ________ mistakes in exams.

The answer lies not in their brain size but in their daily habits. People with good memories usually 16 their brains regularly, just like they exercise their bodies. They understand that memory is a 17 that can be improved with practice. One important habit is getting enough sleep. During sleep, your brain 18 the information you learned during the day. Without enough rest, new information may not 19 your long-term memory. Another useful method is to 20 new information with something you already know. For example, if you learn a new word, try to 21 it with a picture or a story. Stress is another factor that 22 memory. When you are stressed, your brain cannot work at its best. That’s why you might 23 a person’s name during an important conversation. To reduce stress, you can try deep breathing or taking short breaks. Finally, a healthy diet 24 a role in keeping a good memory. Foods like fish, nuts, and vegetables provide nutrients that help your brain function well. As the saying goes, “You are what you eat.” So, if you want to have a better memory, start by 25 small changes to your daily routine. 16．A．exercise B．ignore C．forget D．waste 17．A．gift B．skill C．secret D．problem 18．A．creates B．organizes C．deletes D．hides 19．A．enter B．escape C．leave D．avoid 20．A．compare B．confuse C．connect D．compete 21．A．replace B．associate C．cover D．mix 22．A．improves B．helps C．affects D．creates 23．A．remember B．forget C．recall D．recognize 24．A．plays B．makes C．does D．has 25．A．resisting B．rejecting C．making D．avoiding 【答案】 16．A 17．B 18．B 19．A 20．C 21．B 22．C 23．B 24．A 25．C 【导语】本文是一篇说明文。主要介绍了好记忆力的秘密，包括锻炼大脑、充足睡眠、联想记忆、减轻压力和健康饮食等习惯。 【详解】16．句意：记忆力好的人通常会经常锻炼大脑，就如同锻炼身体一样。 根据后文“just like they exercise their bodies”类比锻炼身体，此处应为锻炼大脑，exercise“锻炼”符合。ignore“忽视”，forget“忘记”，waste“浪费”，均不符合语境。 17．句意：他们明白记忆力是一项可以通过练习提升的技能。 根据定语“that can be improved with practice”可知，能通过练习提高的是技能，skill“技能”匹配。gift“天赋”，secret“秘密”，problem“难题”，不符合文意。 18．句意：在睡眠期间，大脑整理你白天学到的信息。 “your brain...the information”表明，是整理信息。organizes“整理、梳理”，符合睡眠时大脑加工信息的常识。creates“创造”，deletes“删除”，hides“隐藏”，逻辑不通。 19．句意：如果休息不足，新信息可能无法进入长期记忆。 “new information may not...your long-term memory”表明，是新信息可能无法进入长期记忆，enter“进入”，符合记忆形成原理。escape“逃离”，leave“离开”，avoid“避免”，与句意相反。 20．句意：另一个有效的方法是把新信息和已知事物建立联系。 固定搭配connect…with…，意为“把……和……联系起来”。compare“对比”，confuse“使困惑”，compete“竞争”，搭配与含义不符。 21．句意：例如，当你学习新单词，尝试把它和一幅图画或者一个故事关联起来。 根据记忆技巧常识，associate…with是固定搭配，意为“把……和……联系起来”。replace“替换”，cover“覆盖”，mix“混合”，不符合记忆方法的语境。 22．句意：压力是另一个会影响记忆力的因素。 根据下文“brain cannot work at its best”可知，压力有负面影响，affects“影响”，符合语境。improves“提升”，helps“帮助”过于片面；creates“创造”，语义不通。 23．句意：这就是为什么你在重要交谈中可能会忘记别人的名字。 前文说明压力让大脑无法最佳运转，因此会forget“忘记”。remember“记住”，recall“回忆”，recognize“认出”，和语境矛盾。 24．句意：最后，健康饮食对保持良好记忆力起到作用。 固定短语play a role in…，意为“在……方面起作用”。makes、does、has无法构成该短语。 25．句意：所以如果你想要拥有更好的记忆力，可以从对你的日常习惯做出微小改变开始。 “start by...small changes”表明，此处指做出微小改变，固定搭配make changes，意为“做出改变”。resisting“抵抗”，rejecting“拒绝”，avoiding“避免”，语义不匹配。 三、补全对话。(本大题共5小题，每小题1分，共5分) 从 A-F 选出最佳选项，一项多余。 Tom: Hi, you look upset. What’s wrong? Lily: 26 I missed many things Mum asked me to buy. Tom: That’s terrible. 27 Lily: I stay up late every day and have too much stress. Tom: No wonder. 28 Lily: I attended Professor Green’s lecture yesterday. He shared many memory skills. Tom: Great! What’s his most useful tip? Lily: Pay attention to the details of words. 29 Tom: Any other good way? Lily: 30 It’s like building a chain in our brain. A．Why do you forget things so often recently? B．Did you learn any ways to improve memory? C．I forgot to take the shopping list this morning. D．We can link new knowledge with old to remember better. E．You should write down important things and take notes. F．It helps us tell similar words apart and not mix them up. 【答案】26．C 27．A 28．B 29．F 30．D 【导语】本文主要介绍Tom关心情绪低落的Lily，Lily诉说自己购物漏买东西的烦恼，二人围绕健忘的原因、Green教授分享的记忆技巧展开对话。 【详解】26．上文Tom问“你怎么了”，后面说“漏掉很多妈妈要买的东西”。C选项“我今早忘记带购物清单”承接上下文。 27．根据后文回答“I stay up late every day and have too much stress”，可知此处是在询问导致忘事的原因。A选项符合语境逻辑。 28．根据后文“I attended Professor Green’s lecture... He shared many memory skills”，可知此处询问提高记忆力的方式。B选项能引出下文的回答。 29．前文提到的建议是“Pay attention to the details of words”，F选项是对该建议具体作用的进一步解释，逻辑连贯。 30．根据后文“It’s like building a chain in our brain”，D选项的link和chain形成词义呼应，新旧知识相互连接正好对应“搭建链条”这个形象的比喻。 四、阅读理解。(本大题共10小题，每小题2分，共20分) 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.

D．Ran outside. 32．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 33．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. 34．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. 35．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】31．B 32．A 33．B 34．B 35．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】31．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。 32．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。 33．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。 34．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。 35．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。 Grandmother’s Lost Memories Rick’s grandma is over seventy years old. These days, her memory becomes much worse. Last weekend, Rick visited her home and found some strange changes. She kept calling Rick Johnny, which is Rick’s father’s name. When Rick wanted to eat cookies, she told him those snacks were saved for her grandson, not realizing Rick was exactly that grandson. Rick felt really sad and worried about her condition. He talked with his classmate Chen Jie, whose grandpa also has memory problems. Chen told Rick that old people’s memory usually falls little by little as they grow older. His grandpa once forgot the way to their park, so Chen takes him there every weekend. Chen shared a useful idea with Rick: do not only focus on the things the old lady forgets. We should keep in mind all the warm happy memories she still holds. Rick’s grandma still remembers he loves cookies deeply, and this warm memory is very valuable. The two boys discussed what they could do for the elderly with poor memory. They decided to look back on happy family moments together, such as picnics and old opera shows. They planned to take many new photos and make a family photo album for Rick’s grandma. Looking at pictures can help her recall more warm stories from the past. Rick finally understood sadness cannot solve the problem. Instead of feeling upset, he should stay with his grandma and create more new sweet memories with her. 36．Who is Johnny according to the text? A．Rick’s grandfather. B．Rick’s father. C．Chen Jie’s grandpa. D．Rick’s little brother. 37．What trouble does Chen Jie’s grandpa have? A．He forgets the way to the park. B．He cannot remember any food. C．He loses his wallet every day. D．He cannot speak complete sentences. 38．What suggestion did Chen give to Rick? A．Send his grandma to hospital right away. B．Pay more attention to the happy memories she still has. C．Stop visiting his grandma to avoid sadness. D．Teach his grandma new memory skills every day. 39．What plan did the two boys make for Rick’s grandma? A．Buy lots of cookies for her every week. B．Make a family photo album with new photos. C．Take her to watch operas alone every day. D．Move the grandma to live with Rick’s family. 40．What can we learn from Rick’s story? A．Old people will lose all memories completely. B．We should value the warm memories the elderly still keep. C．Sadness can help old people get back their memory. D．Photo albums cannot help recall past moments. 【答案】36．B 37．A 38．B 39．B 40．B 【导语】本文是一篇记叙文，讲述里克的奶奶记忆力衰退，里克为此十分忧心，在同学陈杰的开导下，里克明白不必纠结老人遗忘的事情，应当珍惜老人尚存的温暖记忆，并陪伴奶奶创造更多美好回忆。 【详解】36．第一段原句：“She kept calling Rick Johnny, which is Rick’s father’s name.”，直接说明Johnny是里克的爸爸。 37．第二段原句：“His grandpa once forgot the way to their park”，表明陈杰的爷爷会忘记去公园的路。 38．第三段原句：“do not only focus on the things the old lady forgets.

They demonstrated 64 a new brain stimulation technique can improve memory performance by 20% in healthy adults. The technique uses non-invasive electrical stimulation to enhance the activity of the hippocampus. 65 the researchers said, the results are “promising but still experimental.” It is important 66 people to understand that memory is not fixed. “Your memory ability is not determined at birth,” said Dr. Maria Gonzalez from the Max Planck Institute. “ 67 you train your memory regularly, you can see significant improvements at any age.” The summit also addressed the growing concern about digital dependence. Many participants discussed 68 students are relying too much on smartphones and search engines. They concluded 69 learners should still develop strong foundational memory skills. “Technology should be a tool, not a substitute,” Dr. Li added. The final session focused on the future of memory research. Scientists believe within ten years, we will have a much deeper understanding of how the brain stores and retrieves information. This knowledge could lead to new treatments for memory disorders and better learning strategies for everyone. It is wise 70 young learners to start using science-based memory techniques today.

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. 31．What did Group A do after reviewing words? A．Played games. B．Went to sleep. C．Watched TV. D．Ran outside. 32．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 33．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. 34．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. 35．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.

They concluded 69 learners should still develop strong foundational memory skills. “Technology should be a tool, not a substitute,” Dr. Li added. The final session focused on the future of memory research. Scientists believe within ten years, we will have a much deeper understanding of how the brain stores and retrieves information. This knowledge could lead to new treatments for memory disorders and better learning strategies for everyone. It is wise 70 young learners to start using science-based memory techniques today. With consistent practice, every student can unlock more of their brain’s potential. 八、书面表达(共10分) 71．良好的记忆力对学习至关重要，请你以“How to Improve Our Memory”为题，写一篇英语短文。 内容包括： 1. 良好记忆力的重要性； 2. 提升记忆力的3-4种方法(锻炼、充足睡眠、及时复习、趣味记忆等)； 3. 你的感悟。 要求：80-100词，语法正确，语句通顺，卷面整洁。 ___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 原创精品资源学科网独家享有版权，侵权必究！1 1 / 7 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ 2026-2027学年九年级上册英语单元自测 Unit 4 Our Memory·能力提升 建议用时90分钟，满分100分 1.A 2.C 3.D 4.A 5.C 6.B 7.C 8.B 9.A 10.A 11.
