Unit 4 Our Memory单元检测卷2026-2027学年人教版英语九年级上册

英语人教版新教材九年级上册单元检测卷（附答案） Unit 4 Our Memory 一、阅读理解（20小题，共40分） A a Anterograde amnesia (前行性失忆) is a special kind of memory loss. People with this problem can't form new memories after a brain injury. Their life seems to stop at the moment of the accident. They can talk, eat, and laugh, but they forget everything new the next minute. For example, they may meet you ten times a day, but they will treat you as a stranger every time. It is like living the same day again and again. b Alzheimer's disease (阿尔茨海默病) is a serious health problem for older people. It slowly hurts the brain and causes memory loss. People with this illness often forget recent things first, like what they ate today. Slowly, they forget their family membersˈ names and faces. They finally lose the ability to swallow (吞下) food or breathe, causing them to die. Right now, there is no cure, but doctors can give medicine to help slow it down. c People with hyperthymesia (超忆症) have an amazing memory. They can remember almost every day of their lives. For example, they can tell you exactly what they ate and wore on a certain day many years ago. However, this "superpower" has disadvantages. Sometimes, their brains are too busy remembering the past to focus on the present. And remembering bad days clearly can also bring back painful feelings. 1.How will people with anterograde amnesia treat you after you meet them many times? A. They will forget who you are quickly. B. They will talk and laugh with you happily. C. They will remember your name and face quickly. 2.What can doctors do for people with Alzheimer's disease right now? A. Help them recall recent things. B. Offer a cure for this serious disease. C. Give special medicine to help slow it down. 3.What is one disadvantage of having hyperthymesia? A. People can't make new memories. B. People can't focus on their present life. C. People lose their memories of good days. 4.What is the similarity of the first two diseases? A. They only happen to older people. B. They affect the ability to deal with new information. C. They cause patients to forget how to talk and eat normally. 5.What is the main idea of the three passages? A. The results of brain injuries. B. The mystery of brain diseases. C. Different types of memory conditions. B Teen Talk Discussion: My Way to Keep Family Memories Alive Mei(14,Henan) My way? Last month, I asked Grandma,“What games did you play at 12?” Right away, her eyes lit up! She told me excitedly about playing hopscotch(跳房子) with friends, making toy cars from bamboo sticks and many others I would never learn in any history class. Grandparents are living history books with stories we can't afford to lose. When we listen, we save treasures and make them feel loved. Want to know more about your family? Interview them! Here are some common questions: ● What childhood food made you smile biggest? ● What old-time thing should I try? ● What's the coolest thing I have but you didn't? Ben(15,Guangdong) Last summer, I made a special family tree. I first found some old photos and took pictures of them with my phone. Then, I used AI to build our family tree online. When my grandpa's young photos appeared on the family tree, his eyes got wet! Later, as I typed(打字) in the dates and places our family once stayed, a timeline was created, showing how our family moved from Fujian to Guangdong back in. Seeing how far back our family tree reached, Grandpa said with excitement, “Kid, you made our family history come alive.” Ready to find out your family history? Give it a try this weekend! 6.What did Mei learn from her grandma? A. School subjects. B. Historical buildings. C. Childhood games. 7.Why are the three questions mentioned in Mei's share? A. To write an interesting story. B. To teach some interview skills. C. To open up families' memories. 8.What's the correct order of Ben's actions? Made a timeline. Took pictures of the old photos. Found some old photos. Used AI to build the family tree online. A. B. C. 9.What did Ben's grandpa think of the family tree? A. It was too difficult to understand. B. It reminded him of the hard times. C. It made the family history come alive. 10.What does the passage want to show us? A. How to make grandparents remember well. B. How AI technology is used in everyday life. C. How teens can keep family memories creatively. C You may use your phone to remember some perfect moments in your life. But before you do this, here's a surprising finding that photo-takers need to know: Taking photos is not the perfect memory-retention（记忆储存） way as you think. In fact, taking too many pictures could harm the brain's ability to keep memories, says Elizabeth Loftus, a science professor at the University of California. So you may get the photos but kind of lose memories. It works in two ways, Loftus explains: We either forget the duty of remembering moments when we take pictures of them, or we're so distracted（分心） by the process of taking a photo that we miss the moment. For example, if you write down someone's phone number, you're less likely to remember it at any time because your brain tells you there's just no need. That's OK until that piece of paper goes missing. But photo-takers don't need to feel down. Here are some tips on how to make taking photos help, without harming your memories: Have someone else take the photos. Ask a friend or family member to take photos for you at important events so you can fully enjoy the activity. Pay more attention to the details. If you pay attention to the details of a scene before taking a photo, that process can help keep memories. Look at your photos from time to time. Photos are a useful tool for memory keeping only if we spend time looking through photos, but not everyone can do that. 11.How can taking photos influence people? A. People are easily distracted. B. It can harm people's brains seriously. C. People can remember telephone numbers well. 12.How does the writer support his opinion in Paragraph 2? A. By giving an example. B. By listing numbers. C. By telling the differences. 13.How many ways are there to make taking photos help? A. 2. B. 3. C. 4. 14.What is the writer's attitude（态度） towards taking photos? A. He is against it. B. He never does that. C. He wants to make it helpful. 15.What's the passage mainly about? A. We should take more photos to keep perfect moments in life. B. Why taking photos harms our brains and how to take photos without harming our memories. C. Elizabeth Loftus is a famous science professor who studies memories. D Have you ever forgotten where you left your socks or what you ate for lunch yesterday? You may think being forgetful is bad. But you should be thankful. Scientists from the University of Toronto found that forgetting is actually a key part of learning. Forgetting unnecessary information can help our brains work better. What kind of information is unnecessary? It may depend on your environment. In a changing environment, our brains naturally remember less. For example, a supermarket cashier meets many people every day and remembers them only for a short time. This is because our brains keep making new neurons (神经元) and these neurons cover up unnecessary memories, making room for new information. So our brains help us quickly forget one-time meetings in a changing environment. But a designer often meets the same customers. The brain, in this less changing environment, sees these people as important. It makes the connections stronger, so the designer can remember these customers for a longer time. This process also explains why we forget our early childhood. There is a special area in the brain called the hippocampus (海马体). It is important for our learning and memory. When new neurons enter the hippocampus, they cover up past unnecessary memories, making them hard to find. For most of us, as a result, we forget a lot about our earliest years. Of course, before the brain can decide what to keep or let go, memories must first be stored properly—and that is where sleep comes in. 16.How does the writer start the passage? A. By listing a fact. B. By telling a story. C. By raising a question. 17.Based on the passage and your everyday experience, which situation is most likely to happen? A. Linda forgets an old phone number after learning a new one. B. Regularly changing study locations can keep your brain active. C. A waiter remembers the usual order of a customer who comes every morning. 18.Why do people forget things easily in a changing environment? A. Because the brain gets tired easily. B. Because the brain is always making room for new information. C. Because new neurons in the brain are too busy to store old information. 19.What may the writer talk about next? A. The importance of sleep. B. The tricks of memorizing things. C. The methods to improve memory. 20.What can be the best title for the passage? A. The Key to Having a Good Memory B. Forgetting: Not Always a Bad Thing C. The Secret of Childhood Memoriesˈ Disappearance 二、补全对话（5小题，共10分） Brian:Hi,Cindy.     (21)      Cindy:Hi,Brian.It is nice to see you and so many old classmates.

As I grew up, I became busy and didn't have much time. Later, I stopped doing it. However, the news I came across online touched my heart and changed my mind. A little girl from Jieyang, Guangdong was practising lion dance when a professional lion dance team(专业舞狮队)passed by. As soon as they saw the girl practising, they beat drums and gongs for her and quickly she did a lion dance in return. People around all cheered for her. Her love for the ancient Chinese culture woke up my strong memories of paper cutting. I remembered the happy times of making paper cuts with my teacher and friends in the club. When I was ten, I joined the paper-cutting club. Every Monday and Friday, I learned to make paper cuts there. Our teacher, Ms Li, was very good at it. With a pair of scissors and a piece of paper, she could create lively and amazing works. And we learned much from her. Together, we created lots of works. They covered many topics, including animals, flowers and things about Chinese history. The girl in the news encouraged me to go on with paper cutting. I want to be an inheritor(传承者)of the ancient Chinese culture. Together with other inheritors, I hope to pass down our excellent culture. 46.Why did the writer stop doing paper cutting?                                                                                                                47.What did the lion dance team do when they saw the little girl practising?                                                                                                                48.How often did the writer go to the paper-cutting club?                                                                                                                49.How did the writer like Ms Li's works?                                                                                                                50.What do you think of paper cutting?                                                                                                                六、书面表达（1小题，共20分） 同学们，三年的初中学习生活让你在不断成长和变化。其中，你的英语学习方法也一定发生了许多改变。也许你从过去死记硬背单词，到现在通过阅读故事来记忆；也许你从害怕开口说英语，到现在勇于用英语表达观点……这些变化见证着你的进步。请以“The Changes in My English Learning”为题，写一篇短文。 写作要点: (1)How did you use to learn English and what were the results?

I used to learn English by writing. I spent hours reciting words and grammar rules every day, but I soon forgot them. When I tried to speak or write, I still felt stuck. Now, Iˈve switched to better methods. I learn new words through English stories—this makes remembering them fun and easy. I also attend an English corner twice a week, where I talk with classmates about hobbies or movies. Speaking English no longer scares me. These changes make me get better grades and feel more confident. 第1页，共1页 学科网（北京）股份有限公司 $
