Human memory is not like a video camera that records everything exactly. Instead, it is an active and creative system. Our brains do not simply store copies of experiences; they rebuild them every time we recall something. Scientists divide memory into three main types: sensory memory, shortterm memory and longterm memory. Sensory memory lasts only for a few seconds. It holds what we see, hear or touch for a very short moment. Most of this information disappears unless we pay special attention to it. If we focus on the information, it moves into shortterm memory. Shortterm memory can only hold a small amount of information, usually for less than 30 seconds. Without repetition or connection to something we already know, these messages will be lost. Only information that is deeply processed can enter longterm memory. When you link new facts to your old knowledge, or experience something with strong feelings, the brain is more likely to keep it. However, longterm memory is not perfect. When we retrieve a memory, our brains may fill in missing details with guesses, which means memories can be changed unconsciously. That is why two people who watch the same event may describe it quite differently years later. Many people believe they have a “photographic memory”, which lets them remember every detail forever. Research shows that true photographic memory is extremely rare. Even top memory athletes do not own this superpower. What they master is memory strategies. They connect information with vivid pictures or familiar places to help themselves remember better. These skills are learnable for ordinary people. Memory is also closely connected with forgetting. Forgetting is not always a weakness. It helps our brains cut useless information, so we can make space for new, important things. Without the ability to forget, our minds would be filled with meaningless details and become less efficient. ( )1. What can we learn about human memory from Paragraph 1? A. It records events just as a camera does. B. It forms and rebuilds information actively. C. It can keep all our experiences forever. D. It works well without any rebuilding. ( )2. Information can move from shortterm memory into longterm memory when ______. A. it stays in our mind for over 30 seconds naturally B. we pay no attention to the small details C. we process it deeply and connect it with known knowledge D. it comes from our sensory memory directly ( )3. The underlined word “retrieve” in Paragraph 3 most probably means ______. A. recall B. change C. compare D. create ( )4. Which statement is TRUE according to the passage? A. Photographic memory is common among memory athletes. B. Strong feelings stop information from entering longterm memory. C. Forgetting sometimes helps our brains work better. D. People can easily remember everything they see. ( )5. What is the main idea of the passage? A. Ways to improve shortterm memory quickly. B. Different kinds of memory and how they work. C. The disadvantages of longterm memory. D. The reasons why people easily forget things. Passage B When Emma was 16, she lost her grandma, who was the person she loved most. She was afraid that as time passed, her memories of grandma would become unclear and finally disappear. To fight against forgetting, she started a special memory journal. She did not only write down big events, such as their trips together. She recorded tiny, ordinary moments: the smell of grandma’s apple pie, the slow sound of her voice when telling old stories, the warm touch of her rough hands. At first, Emma thought the journal would just be a tool to store facts. But slowly, she found something surprising. Some memories she had written down felt more real, while some other old memories she had not recorded began to shift. Once, she argued with her aunt about whether grandma liked roses or lilies. Emma was sure it was roses, until she read her own journal entry written one week after grandma’s death. The words on the page said lilies. A psychology professor explained this to her. “We often trust our personal memories completely. But memory is not a locked box. Every time we bring a memory back, we edit it a little. Our feelings, new experiences and even suggestions from others can change it. Writing things down early can hold a relatively reliable version, but the written record itself also becomes a new memory.” Later, Emma stopped treating the journal as a perfect copy of the past. She realized that memory was not about keeping every single detail correct. What mattered was the feeling carried inside those memories. Even if small details changed, the love and warmth grandma gave her stayed. She also shared her discovery with her classmates. Many teenagers worry about losing precious memories of loved ones. Emma told them: It is normal for memories to change. The value of memory lies not in perfect accuracy, but in how it shapes who we are and how we carry love forward. ( )1. Why did Emma begin to keep the memory journal? A. To finish her school writing task. B. To stop her memories of grandma from fading. C. To study the rules of human memory for a report. D. To help her aunt remember grandma’s favourite flowers. ( )2. What made Emma surprised after keeping the journal for some time? A. All her memories became clearer than before. B. Some unwritten memories changed little by little. C. She forgot how grandma’s apple pie tasted. D. Her aunt agreed with all her ideas about grandma. ( )3. What does the professor mean by saying “memory is not a locked box”? A. Memories are fixed and cannot be changed. B. We can lock our memories away safely. C. Memories may be changed when we recall them. D. It is impossible to store memories for long. ( )4. What can we infer from the passage? A. We should never trust our own memories. B. A journal can keep memories completely unchanged. C. Feelings in memories are more important than tiny details. D. Most people can remember all details of their loved ones. ( )5. What is the writer’s purpose in writing this story? A. To introduce a useful way to keep perfect memories. B. To show that memory is changeable and talk about its true value. C. To advise all students to keep diaries every day. D. To explain why people always argue about old stories. 参考答案 + 解析 一、词形转换单句填空 1. memorize 解析：It’s +adj.+to do，to 后面接动词原形；memory (n.)→memorize (v. 记住)。 2. memory 解析：形容词 good 修饰名词 memory，记忆力。 3. sadness 解析：形容词 great 后接名词；sad (adj.)→sadness (n. 悲伤)。 4. retell 解析：will 情态动词，后面接动词原形 retell 复述。 5. brain(s) 解析：brain 大脑；our 后可接单数或复数 brain/brains。 6. position 解析：your 形容词性物主代词，后接名词 position 位置。 7. react 解析：didn’t 后面使用动词原形；react to 对…… 作出反应。 8. chain 解析：this 后接单数名词 chain 链条。 9. lecture 解析：a 后接单数名词 lecture 讲座。 10. stable 解析：keep sth +adj. 使某物保持……；stable 稳定的。 11. grandson 解析：my 形容词性物主代词，grandson 孙子，名词。 12. case 解析：in one’s case 在某人的情况里，固定搭配。 13. memories 解析：many 后接可数名词复数，memory 表示回忆时常用 memories。 14. recall 解析：should 情态动词，后接动词原形 recall 回忆起。 15. image 解析：this 修饰单数名词 image 图像。 16.
