He shows everybody that goldfish are smarter than we think. “I don’t believe that they have a seven-second memory because animals need their memories, so they can know where the food is,” he said. He did the experiment in a small box of goldfish. “I decided to get a red mark and just feed them next to the mark. Every day I put it in and dropped food around it,” he said. “At first they were a bit afraid of it, but by the end of the three weeks, they were actually almost coming before I put the food in.” After leaving the goldfish alone for a week, Roy put the red mark in the box again. “They remembered perfectly well,” he said. “They actually had a time faster than the three feeds before I left.” The goldfish showed that they not only could store information, but also had the ability to get it back at a later date. Colum Brown, a researcher at Macquarie University in Sydney, has studied fish behavior for more than ten years. He says his studies show that fish are smart and that they know how to avoid enemies (躲避敌人) and catch food like any other animal. As an experienced expert, Colum thinks that Roy’s experiment is really good. 5. Roy began his research by ________. A. discussing with his classmates B. making friends with goldfish C. asking his teacher for advice D. questioning a popular idea 6. What is the right order of Roy’s experiment? ① get a red mark and feed them           ② leave the goldfish alone for a week ③ put the mark back into the box          ④ find a box of goldfish A. ④①②③ B. ④③①② C. ①③②④ D. ③②④① 7. Roy’s experiment tells us that ________. A. goldfish have a seven-second memory B. goldfish can catch enemies like any other animal C. goldfish cannot catch food like any other animal D. goldfish are smarter than we think 8. What’s the writer’s purpose in writing the passage? A. To tell us goldfish have a seven-second memory. B. To introduce a young goldfish expert. C. To tell us a new study beats against goldfish memory myth (神话). D. To show us how goldfish learn and remember. 【答案】5. D 6. A 7. D 8. C 【知识点】常见动物、说明文 【导语】本文主要讲述了许多人认为金鱼只有七秒钟的记忆，但是15岁的Roy Stokes通过实验证明金鱼比我们想象的要聪明得多。 5. 细节理解题。根据“Many people believe that goldfish only have a seven-second memory, but Roy Stokes, a 15-year-old schoolboy from Australian Science and Mathematics School has just finished an experiment to tell us that it is not true.”可知，他的研究是从质疑一种流行的说法开始的。故选D。 6. 细节理解题。根据“He did the experiment in a small box of goldfish…I decided to get a red mark and just feed them next to the mark”；“After leaving the goldfish alone for a week, Roy put the red mark in the box again.”可知，正确顺序是：找一箱金鱼→画一个红色标记，喂它们→让金鱼单独待一个星期→把标记放回箱子里。故选A。 7. 细节理解题。根据“He shows everybody that goldfish are smarter than we think.”可知，金鱼比我们想象的要聪明。故选D。 8. 主旨大意题。通读全文可知，本文主要讲述了许多人认为金鱼只有七秒钟的记忆，但是15岁的Roy Stokes通过实验证明金鱼比我们想象的要聪明得多，C项“告诉我们一项新的研究打破了金鱼记忆的神话”符合。故选C。 C How is your memory? Remembering things is an important job of our brain. If we can’t recall how to do something, we can’t survive. Memory allows the brain to store and retrieve information when required. Our short-term memory can hold a small amount of information for a short time, while our long-term memory can hold an unlimited (无限的) amount of information for a long time. Our memory is amazing, but why do we still forget things? It’s possible we don’t always store information in our memory effectively, maybe because we are in a rush or we consider it irrelevant (不相关的) at the time. When we do store information, we often make connections with other things, which helps us recall it later. If you don’t have these connections, then it can be easier to forget. Writing for the BBC’s Science Focus magazine, Luis Villazon says, “It is also possible that memories decay (衰退) over time. As they have not been revisited, their biological ‘trace’ becomes weak.” It’s true that if you don’t perform a task for a long period of time, it can be difficult to recall how to do it. But sometimes even our short-term memory can let us down. Have you ever gone into a room to get something only to forget what you wanted when you got there? This is called “The Doorway Effect”. Writing for the BBC Future website, Tom Stafford explains that this occurs because we change both the physical and mental (精神的) environments, moving to a different room and thinking about different things. So, if you always forget things, it could be because you have too much on your mind. But we do need to keep our memory sharp by continually using it. 9. What can we know from the second paragraph? A. Different things are hard to remember at one time. B. Making connections helps you remember things better. C. Things will not be forgotten as you consider it important. D. The biological “trace” becomes weak as one grows older. 10. How does the writer explain what “The Doorway Effect” is? A. By listing numbers. B. By doing research. C. By asking questions. D. By giving examples. 11. Which of the following can be called “The Doorway Effect”? A. You forget what you have learned in your middle school. B. You forget how to drive a car when not driving for years. C. You forget some of your classmates’ names after graduation. D. You forget something to buy when you get to the supermarket. 12. How can you remember English words better according to the text? A. Write the words again and again on the paper. B. Memorize words by repeating them 100 times. C. Connect words to other things and often use them. D. Memorize all the words in a day and not use them again. 【答案】9. B 10. D 11. D 12. C 【导语】本文探讨了人类记忆的作用、特性及遗忘的原因。 9. 细节理解题。根据“When we do store information, we often make connections with other things, which helps us recall it later.”可知，当我们储存信息时，我们经常会将其与其他事物联系起来，这有助于我们以后回忆起它，建立联系可以帮助你更好地记住事情。故选B。 10. 细节理解题。根据“Have you ever gone into a room to get something only to forget what you wanted when you got there? This is called ‘The Doorway Effect’.”可知，作者通过举例子来解释“门口效应”。故选D。 11. 推理判断题。根据“Have you ever gone into a room to get something only to forget what you wanted when you got there? This is called ‘The Doorway Effect’.”可知，“门口效应”是指当我们进入一个新环境或改变环境时，我们可能会忘记原本打算做的事情。D项“当你到达超市时忘记要买的东西”符合这一描述。故选D。 12. 推理判断题。根据“When we do store information, we often make connections with other things, which helps us recall it later.”可知，当我们存储信息时，我们通常会与其他事物建立联系，这有助于我们以后回忆这些信息。因此，为了更好地记住英语单词，我们应该将单词与其他事物联系起来，并经常使用它们。故选C。 D Do you have memories from when you were a baby? Most of us don’t have them. This is called “childhood amnesia (童年失忆症)”. However, these memories are actually kept in the brain until we become adults, even though we aren’t aware of them. Professor Cristina Alberini at New York University found that the experiences learned in infancy (婴幼儿期) are kept as hidden memories. It happens in the hippocampus when an infant’s (婴儿的) brain is growing. Changes in brain chemicals help this process. Alberini did experiments on mice and found that adding some chemicals later can bring back hidden memories. This shows that early memories aren’t lost but are kept. “If the children are learning difficult situations in early childhood, their brains are going to be shaped based on that experience,” Alberini said. Her study shows these hidden memories may influence people’s learning abilities throughout their lives and lead to some mental (精神的) health illnesses. Although most of us can’t remember the things that happened to us when we were little, the age at which each person has their first memory can be different. Different backgrounds may explain the difference. Professor Wang Qi at Cornell University in the US has shown that the earliest memories of Americans date back to around 3.5 years of age, almost six months earlier than in Chinese people. Wang said that this is because American people are more self-focused (以自我为中心). However, in Asia, people play more roles in society and have more relationships with others. So it may take more time for Asian babies to remember many details. How often parents talk about past experiences with their children can also influence when first memories appear. New Zealand’s Maori people have their first memories as early as at the age of 2.5. It’s because the Maori culture values stories and deep conversations about past events. Conversations are key for keeping memories when kids can form mental images of the things that happened to them. 13. According to the passage, “childhood amnesia” refers to ________. A. inability to recall early childhood experiences B. difficulty children have forming (形成) memories C. worry about the truth of early memories D. loss of memory abilities in the childhood 14. According to the passage, the underlined word “hippocampus” is probably __________. A. a name of a scientific experiment B. a part of human brain C. a kind of special medicine D. a kind of chemicals 15. According to the passage, __________ are the one who form first memories earliest. A. Chinese people. B. American people. C. European people. D. Maori people. 16. On which website can we probably read the above passage? A. www.crossculture.com B. www.mentalhealth.com C. www.brainandmemory.com D. www.scienceandtech.com 【答案】13. A 14. B 15. D 16. C 【知识点】科普知识、说明文 【导语】本文主要讲述了“童年失忆症”现象及其相关研究，探讨了早期记忆的形成、存储以及不同文化背景下人们首次记忆的年龄差异。 13. 细节理解题。根据文章第1段“Do you have memories from when you were a baby? Most of us don’t have them. This is called ‘childhood amnesia’.”可知，“童年失忆症”指的是无法回忆起早期童年经历。故选A。 14. 词句猜测题。根据文章第2段“It happens in the hippocampus when an infant’s brain is growing.”可推知，“hippocampus”是大脑的一部分。故选B。 15. 细节理解题。根据最后一段“New Zealand’s Maori people have their first memories as early as at the age of 2.5.”可知，毛利人是最早形成第一次记忆的人群。故选D。 16. 推理判断题。结合上下文可知，本文主要讨论了记忆的形成、存储以及相关研究，涉及大脑科学和记忆机制。因此，最有可能发布这类文章的网站是与大脑和记忆相关的网站。故选C。 第二节：阅读短文，从文后所给的选项中选出可以填入空白处的最佳选项，其中有一个多余选项。 From English words to history events, you have to remember a lot at school. Is it difficult? Do you want to find some good ways to remember easily and quickly? If you have a photographic memory (过目不忘的记忆), will things be different? Scientists have made an effort to find ways to improve our memories for years. 17 . Sleeping in a rocking bed When we were babies, we could easily fall asleep in our mothers’ swaying (摇晃的) arms. Some scientists have found that if we sleep in a bed which moves softly forwards and backwards, we can have a deeper sleep. 18 . Buying a rocking bed may be a good idea and it must be very fun. Haha! Becoming emotional (情绪化) Thinking back to the past, it seems that we could always remember those things that make us sad or happy easily. Why? 19 . The moment you become emotional, you can remember things really well. Because the amygdala (杏仁体) in our brain is responsible for dealing with both emotions and memories. The brain wants us to remember those things. When you want to remember some knowledge next time, try to make yourself angry or excited. Then, take out your book to catch the chance to learn new things. 20 . In an experiment, it shows that the short but intense (剧烈的) exercise made the brain produce more of a chemical called “brain-derived neurotrophic factor” (脑源性神经营养因子). People can remember things quickly with this chemical. A. Because emotions can influence memories B. Having intense exercise C. Here are some tips from their findings D. Because memories can influence emotions E. It can improve our memories as well 【答案】17. C 18. E 19. A 20. B 【导语】本文介绍了几种提高记忆的方法。 17. 根据“Scientists have made an effort to find ways to improve our memories for years”及下文介绍的一些提高记忆的方法，可知此处用来引出下文，选项C“以下是他们研究结果中的一些提示”符合语境，故选C。 18. 根据“Some scientists have found that if we sleep in a bed which moves softly forwards and backwards, we can have a deeper sleep.”可知如果我们睡在前后轻轻移动的床上，我们可以获得更深的睡眠。选项E“它也能提升我们的记忆力”符合语境，故选E。 19. 根据“Thinking back to the past, it seems that we could always remember those things that make us sad or happy easily. Why?”可知此处解释我们总是容易记住那些让我们感到悲伤或快乐的事情的原因，选项A“因为情绪可以影响记忆”符合语境，故选A。 20. 根据“In an experiment, it shows that the short but intense (剧烈的) exercise made the brain produce more of a chemical called ‘brain-derived neurotrophic factor’ (脑源性神经营养因子) . People can remember things quickly with this chemical.”可知此处介绍剧烈运动使大脑产生更多的有助于人们快速记住事物的化学物质，选项B“进行剧烈运动”符合语境，故选B。 二、完形填空（10分）(文章嵌入本单元所学的单词和短语，极好吻合课文所学知识) Do you sometimes forget things?

Now scientists have found exactly when these memories 31 (appear). A new study has found that most three-year-old children can remember a lot of what happened to them a year 32 (early),and these memories are still clear while they are 5 and 6, but by the time they are over 7, these memories become weak 33 (quick). Most children by the age of 8 or 9 can only remember 35% of their experiences from under the age of 3 according to the new studies. The scientists say this is 34 at around this age the way we form memories begins to change. They say that before the age of 7 children do not have a sense of time and place in their memories. In older children, however, the early things they can remember become more adult-like 35 the way they are formed. Children also have a far faster speed of 36 (forget) than adults. The discoveries also help to explain 37 children can often have clear memories of what they have done, but then forget them just several years later. The children were organized to the laboratory for the first time at the age of 3 and discussed 6 impressed (印象深刻的) things from their past，such 38 the first relaxing trip with your family, the first accident you met with, and the first day of school. The children then returned for a second period between the 39 (age) of 5 and 9 to discuss the same things. The scientists found that between the ages of 5 and 7，the amount (量) of memories that the children could remember 40 (remain) between 63%—72%.

A. there are many ways to improve your memory B. you can never improve your memory because it was born with your life C. crossword puzzles are not good for improving memory D. you can remember all the things if you don’t think about anything else B Many people believe that goldfish only have a seven-second memory, but Roy Stokes, a 15-year-old schoolboy from Australian Science and Mathematics School has just finished an experiment to tell us that it is not true. He shows everybody that goldfish are smarter than we think. “I don’t believe that they have a seven-second memory because animals need their memories, so they can know where the food is,” he said. He did the experiment in a small box of goldfish. “I decided to get a red mark and just feed them next to the mark. Every day I put it in and dropped food around it,” he said. “At first they were a bit afraid of it, but by the end of the three weeks, they were actually almost coming before I put the food in.” After leaving the goldfish alone for a week, Roy put the red mark in the box again. “They remembered perfectly well,” he said. “They actually had a time faster than the three feeds before I left.” The goldfish showed that they not only could store information, but also had the ability to get it back at a later date. Colum Brown, a researcher at Macquarie University in Sydney, has studied fish behavior for more than ten years. He says his studies show that fish are smart and that they know how to avoid enemies (躲避敌人) and catch food like any other animal. As an experienced expert, Colum thinks that Roy’s experiment is really good. 5. Roy began his research by ________. A. discussing with his classmates B. making friends with goldfish C. asking his teacher for advice D. questioning a popular idea 6. What is the right order of Roy’s experiment? ① get a red mark and feed them           ② leave the goldfish alone for a week ③ put the mark back into the box          ④ find a box of goldfish A. ④①②③ B. ④③①② C. ①③②④ D. ③②④① 7. Roy’s experiment tells us that ________. A. goldfish have a seven-second memory B. goldfish can catch enemies like any other animal C. goldfish cannot catch food like any other animal D. goldfish are smarter than we think 8. What’s the writer’s purpose in writing the passage? A. To tell us goldfish have a seven-second memory. B. To introduce a young goldfish expert. C. To tell us a new study beats against goldfish memory myth (神话). D. To show us how goldfish learn and remember. C How is your memory? Remembering things is an important job of our brain. If we can’t recall how to do something, we can’t survive. Memory allows the brain to store and retrieve information when required. Our short-term memory can hold a small amount of information for a short time, while our long-term memory can hold an unlimited (无限的) amount of information for a long time. Our memory is amazing, but why do we still forget things? It’s possible we don’t always store information in our memory effectively, maybe because we are in a rush or we consider it irrelevant (不相关的) at the time. When we do store information, we often make connections with other things, which helps us recall it later. If you don’t have these connections, then it can be easier to forget. Writing for the BBC’s Science Focus magazine, Luis Villazon says, “It is also possible that memories decay (衰退) over time. As they have not been revisited, their biological ‘trace’ becomes weak.” It’s true that if you don’t perform a task for a long period of time, it can be difficult to recall how to do it. But sometimes even our short-term memory can let us down. Have you ever gone into a room to get something only to forget what you wanted when you got there? This is called “The Doorway Effect”. Writing for the BBC Future website, Tom Stafford explains that this occurs because we change both the physical and mental (精神的) environments, moving to a different room and thinking about different things. So, if you always forget things, it could be because you have too much on your mind. But we do need to keep our memory sharp by continually using it. 9. What can we know from the second paragraph? A. Different things are hard to remember at one time. B. Making connections helps you remember things better. C. Things will not be forgotten as you consider it important. D. The biological “trace” becomes weak as one grows older. 10. How does the writer explain what “The Doorway Effect” is? A. By listing numbers. B. By doing research. C. By asking questions. D. By giving examples. 11. Which of the following can be called “The Doorway Effect”? A. You forget what you have learned in your middle school. B. You forget how to drive a car when not driving for years. C. You forget some of your classmates’ names after graduation. D. You forget something to buy when you get to the supermarket. 12. How can you remember English words better according to the text? A. Write the words again and again on the paper. B. Memorize words by repeating them 100 times. C. Connect words to other things and often use them. D. Memorize all the words in a day and not use them again. D Do you have memories from when you were a baby? Most of us don’t have them. This is called “childhood amnesia (童年失忆症)”. However, these memories are actually kept in the brain until we become adults, even though we aren’t aware of them. Professor Cristina Alberini at New York University found that the experiences learned in infancy (婴幼儿期) are kept as hidden memories. It happens in the hippocampus when an infant’s (婴儿的) brain is growing. Changes in brain chemicals help this process. Alberini did experiments on mice and found that adding some chemicals later can bring back hidden memories. This shows that early memories aren’t lost but are kept. “If the children are learning difficult situations in early childhood, their brains are going to be shaped based on that experience,” Alberini said. Her study shows these hidden memories may influence people’s learning abilities throughout their lives and lead to some mental (精神的) health illnesses. Although most of us can’t remember the things that happened to us when we were little, the age at which each person has their first memory can be different. Different backgrounds may explain the difference. Professor Wang Qi at Cornell University in the US has shown that the earliest memories of Americans date back to around 3.5 years of age, almost six months earlier than in Chinese people. Wang said that this is because American people are more self-focused (以自我为中心). However, in Asia, people play more roles in society and have more relationships with others. So it may take more time for Asian babies to remember many details. How often parents talk about past experiences with their children can also influence when first memories appear. New Zealand’s Maori people have their first memories as early as at the age of 2.5. It’s because the Maori culture values stories and deep conversations about past events. Conversations are key for keeping memories when kids can form mental images of the things that happened to them. 13. According to the passage, “childhood amnesia” refers to ________. A. inability to recall early childhood experiences B. difficulty children have forming (形成) memories C. worry about the truth of early memories D. loss of memory abilities in the childhood 14. According to the passage, the underlined word “hippocampus” is probably __________. A. a name of a scientific experiment B. a part of human brain C. a kind of special medicine D. a kind of chemicals 15. According to the passage, __________ are the one who form first memories earliest. A. Chinese people. B. American people. C. European people. D. Maori people. 16. On which website can we probably read the above passage? A. www.crossculture.com B. www.mentalhealth.com C. www.brainandmemory.com D. www.scienceandtech.com 第二节：阅读短文，从文后所给的选项中选出可以填入空白处的最佳选项，其中有一个多余选项。 From English words to history events, you have to remember a lot at school. Is it difficult? Do you want to find some good ways to remember easily and quickly? If you have a photographic memory (过目不忘的记忆), will things be different? Scientists have made an effort to find ways to improve our memories for years. 17 . Sleeping in a rocking bed When we were babies, we could easily fall asleep in our mothers’ swaying (摇晃的) arms. Some scientists have found that if we sleep in a bed which moves softly forwards and backwards, we can have a deeper sleep. 18 . Buying a rocking bed may be a good idea and it must be very fun. Haha! Becoming emotional (情绪化) Thinking back to the past, it seems that we could always remember those things that make us sad or happy easily. Why? 19 . The moment you become emotional, you can remember things really well. Because the amygdala (杏仁体) in our brain is responsible for dealing with both emotions and memories. The brain wants us to remember those things. When you want to remember some knowledge next time, try to make yourself angry or excited. Then, take out your book to catch the chance to learn new things. 20 . In an experiment, it shows that the short but intense (剧烈的) exercise made the brain produce more of a chemical called “brain-derived neurotrophic factor” (脑源性神经营养因子). People can remember things quickly with this chemical. A. Because emotions can influence memories B. Having intense exercise C. Here are some tips from their findings D. Because memories can influence emotions E. It can improve our memories as well 二、完形填空（10分）(文章嵌入本单元所学的单词和短语，极好吻合课文所学知识) Do you sometimes forget things?

Now scientists have found exactly when these memories 31 (appear). A new study has found that most three-year-old children can remember a lot of what happened to them a year 32 (early),and these memories are still clear while they are 5 and 6, but by the time they are over 7, these memories become weak 33 (quick). Most children by the age of 8 or 9 can only remember 35% of their experiences from under the age of 3 according to the new studies. The scientists say this is 34 at around this age the way we form memories begins to change. They say that before the age of 7 children do not have a sense of time and place in their memories. In older children, however, the early things they can remember become more adult-like 35 the way they are formed. Children also have a far faster speed of 36 (forget) than adults. The discoveries also help to explain 37 children can often have clear memories of what they have done, but then forget them just several years later. The children were organized to the laboratory for the first time at the age of 3 and discussed 6 impressed (印象深刻的) things from their past，such 38 the first relaxing trip with your family, the first accident you met with, and the first day of school. The children then returned for a second period between the 39 (age) of 5 and 9 to discuss the same things. The scientists found that between the ages of 5 and 7，the amount (量) of memories that the children could remember 40 (remain) between 63%—72%. However, between the ages of 8 to 9, the amount of memories that the children could remember fell to between 35%—36%. 四、阅读与表达（共4小题,41〜43小题，每题2分,44小题4分；满分10分） 阅读短文，然后根据内容回答问题。 Jane grew up with her grandma.
