But they only used the stick to get a banana when both the banana and the stick were in view at the same time. If the banana was in front of them and the stick was behind them, they could not use the stick. They could not keep the banana 5 enough in mind to look around and then pick up the stick and use it.The 6 for this is clear. We have words for banana and stick which help use to think about these things when they are not in 7 . Even a small child knowing the words "banana" and "stick" has an idea of their relationship and is able to think "stick" together with "banana" and to remember this long enough to pick the stick 8 behind and use it on the banana.9 to speak, animals cannot keep their knowledge of things for long.

There is nothing very new in growing grapes in Britain, 3 the climate. The Romans planted the first vines about AD 300 and 4 a long time people always drank home-produced wines. What destroyed the English wine industry was not5 a change in the climate as the fact that an English King, Henry II, inherited the Bordeaux area of France as part of his dominions6the twelfth century and the imported wine provided7 of competition. The English wine industry did not disappear, however,8the sixteenth century, when the monks, who had been the main producers in the meantime, had their estates taken away by Henry VIII.

Life for these people is different from that for younger Americans. Most senior citizens retire, or no longer work full time. Also it is unusual for people of this age to live with their children and grandchildren. Grandparents tend to live in their own houses or apartments away from their families.For many senior citizens, the years after 65 are not enjoyable. They feel unproductive when they no longer work. Their lives lose meaning. In addition, they may feel lonely being away from their families and the contacts they had in their work. Moreover, they become more concerned with their health as they grow older. If they live in big cities, they often worry about their safety.Other senior citizens enjoy their lives. They feel free to do things they were not able to do when they were working and raising families. They now have time to enjoy hobbies and sports and travel. They associate with their fellow senior citizens who have common interests and equal free time. Many senior citizens move to retirement communities located in warm climates. Some senior citizens continue to work beyond retirement age. Many find new careers and professional opportunities after they retire.The number of senior citizens in the U.S.A is increasing rapidly because people are living longer than before. The average life span for Americans in now more than 74 years. Because of their larger numbers and more active life styles, senior citizens are gaining social influence in the country both politically and economically. Their concerns are receiving a wider audience than ever before. The time may come when all Americans will look forward to becoming senior citizens.1．Many senior citizen ________.A）are enjoyable B）live together with their familiesC）feel unproductive, lonely and unsafe D）feel safe in big cities 2．Senior citizens are gaining social influence because ________.A）the number of senior citizens is growing and because senior citizens are more activeB）senior citizens have experienceC）their average life span is longerD）they do more work now3．Implied but not stated: ________.A）Most of American senior citizens have lived a lonely and unhappy life. B）They have played an important part in society.C）Like young people, senior citizens can still enjoy everything they like.D）Their average lifespan is becoming longer and longer.Passage 2The Great Fire of London started in the very early hours of 2 September 1666. In four days it destroyed more than three-quarters of the old city, where most of the houses were wooden and close together. One hundred thousand people became homeless, but only a few lost their lives.The fire started on Sunday morning in the house of the King's baker in Pudding Lane. The baker, with his wife and family, was able to get out through a window in the roof. A strong wind blew the fire from the bakery into a small hotel next door. Then it spread quickly into Thames Street. That was the beginning.By eight o'clock three hundred houses were on fire. On Monday nearly a kilometer of the city was burning along the River Thames. Tuesday was the worst day. The fire destroyed many well-known buildings, old St Paul's and the Guildhall among them.Samuel Pepys, the famous writer, wrote about the fire. People threw their things into the river. Many poor people stayed in their houses until the last moment. Birds fell out of the air because of the heat.The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the path of the fire. With nothing left to burn, the fire became weak and finally died out.After the fire, Christopher Wren, the architect, wanted a city with wider streets and fine new houses of stone. In fact, the streets are still narrow; but he did build more than fifty churches, among them new St Paul's.The fire caused great pain and loss, but after it London was a better place: a city for the future and not just of the past.4．The fire began in______.A）a hotel B）the palaceC）Pudding Lane D）Thames Street5．It seems that the writer of the text was most sorry for the fact that______.A）some people lost their lives B）the birds in the sky were killed by the fireC）many famous buildings were destroyed D）the King's bakery wasburned down6．Why did the writer cite Samuel Pepys? ______A）Because Pepys was among those putting out the fireB）Because Pepys also wrote about the fireC）To show that poor people suffered mostD）To give the reader a clearer picture of the fire7．How was the fire put out according to the text? ______.A）The king and his soldiers came to helpB）All the wooden houses in the city were destroyedC）People managed to get enough water from the riverD）Houses standing in the direction of the fire were pulled downPassage 3Music which is original is individual and personal. That is to say, it can be identified as belonging to a particular composer. It has particular qualities, or a style, which are not copied from another. If you can recognize the style of a composer, you will probably be able to tell that a certain composition belongs to him or her even though you have never heard it before. A composer organizes his melodies (旋律) and rhythms and combines sounds to create harmony. He may be capable of thinking up very good, original tunes, yet if tunes are poorly organized, the final result will not be to standard.Good music expresses feelings in a way that is suitable to those feelings. There may be joy, sorrow, fear, love, anger, or whatever. Bad music, on the other hand, may confuse unrelated feelings, it may not express any important feeling at all, or it may exaggerate some feelings and make them vulgar, that is, cheap and ugly.Good music will stand the test of time. It will not go out of fashion but will continue to be enjoyed and respected long after it is first introduced. It will gain a kind of permanent status while bad music will disappear and be forgotten quickly. In pop music, where the general rule seems to be "the newer the better", the test of time is the hardest test of all to pass.1．A piece of original music ______.A）has a personal style B）sounds very familiar to our earsC）is one whose style you cannot recognize D）cannot be recognized as belonging to any composer2．Good music is ______.A）well-organized tunes B）the proper expression of feelingsC）an expression of mixed feelings D）exaggeration of some feelings3．The passage is concerned with ______.A）how to compose music B）how to enjoy musicC）how to judge music D）how to perform musicPassage 4Shopping-bag ladies don't beg publicly, but they do not refuse what is offered. Once a shopping-bag lady appears where you live, it is as hard to pass her by without giving her some money as it is to pay no attention to the collection box in church. And although you may not like it, if she chooses your doorway as her place to sleep in the night, it is as morally hard to turn her away as it is to do with a lost dog.Most shopping-bag ladies seem to be between the ages of 40 and 65. They wear layers of clothes even in summer time, with newspapers filled between the layers as something against bad weather.No one knows how many shopping-bag ladies there are in New York. The number is going up. Some persons and researchers spend a great deal of time taking care of or observing shopping-bag ladies and doing what they can to better the life lady hermits（隐士） who're down.1．Shopping-bag ladies are ______.A）lady beggars B）ladies who sell shopping-bagsC）ladies who make shopping-bags D）Those who go hungry 2．They fill newspapers between the layers of their clothes because ______.A）they are so poor B）they have no place to put themC）they want to hide them D）they have to use them to keep the cold out3．Which of the following statements is NOT true.A）There are more and more shopping-bag ladies in the United States .B）Shopping-bag ladies appear only in New York.C）Some people are helping shopping-bag ladies.D）Some people are engaged in their research on these shopping-bag ladies. Passage 5The Internet will play a central role in conducting international trade beyond the year 2000. The World Trade Centers Association (WTCA) recently announced a plan to assist developing countries develop a capacity for e-commerce and e-business. The spin off from this decision can pay huge dividends to offshore companies that position themselves on-line right now to supply goods and services to the coming global Internet trading market.E-business will help you get set up and operate with a minimum of effort and at reasonable prices.E-business Incorporated works with international companies to set up a web-office, or CyberSuite as its own domain accessible over the Internet via its owndomain name or from the e-business Cyberspace Station.If you are a supplier, your CyberSuite would have a showroom where visitors —especially wholesale importers and distributors — can examine images, drawings or listings of what you have to offer. If you are a buyer, your web-office can include a notice board listing products or services or agreements you are looking for and a bidding gallery where suppliers can post bids and link you to their sites to examine products. Trading partners can make purchases, send invoices, hold business meetings, track shipments, and work out potential trade agreements within the E-business Cyberspace Station. E-business seminars and conferences will introduce new potential trade partners to each other.Orders placed on the site are sent immediately to manufacturers and any suppliers integrated into the trade process. For example, established trading partners might include an importer ordering large shipments from a manufacturer and suppliers of parts or raw materials in other countries. By electronically notifying the whole trade net at the same time, each partner is able to trim supply and demand to "just in time" delivery of goods or services. The savings of doing business this way can be substantial — even without the tax advantages.1．E-business Incorporated can help a company to______.A）set up a web-office free of charge B）build a Cybersuite as its domainC）get its own domain name D）have its web site accessible via its own domain name2．In a Cybersuite, a supplier can ______.A）exhibit its products and services B）find more images and drawingsC）get many lists of products D）bid for a certain product or service3．The passage mainly tells about ______.A）the benefits brought by e-business B）how to do e-commerce via InternetC）a project by WTCA D）how to find trade partners via InternetPassage 6For some time past it has been widely accepted that babies - and other creatures - learn to do things because certain acts lead to "rewards"; and there is no reason to doubt that this is true. But it used also to be widely believed that effective reward, at least in the early stages, had to be directly related to such basic physiological (生理的) "drives" as thirst or hunger. In other words, a baby would learn if he got food or drink of some sort of physical comfort, not otherwise.It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except the successful outcome.Papousek began his studies by using milk in the normal way to "reward" thebabies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement "switched on" a display of lights - and indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make as many three turns to one side.Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely although they would "smile and bubble" when the display came on. Papousek concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control.4．According to the author, babies learn to do things which ______.A）are directly related to pleasure B）will meet their physical needsC）will bring them a feeling of success D）will satisfy their curiosity 5．Papousek noticed in his studies that a baby ______.A）would make learned responses when it saw the milkB）would carry out learned movements when it had enough to drinkC）would continue the simple movements without being given milkD）would turn its head to right or left when it had enough to drink6．In Papousek's experiment babies make learned movements of the head in order to______.A）have the lights turned on B）be rewarded with milk C）please their parents D）be praised7．The babies would "smile and bubble" at the lights because ______.A）the lights were directly related to some basic "drives"B）the sight of the lights was interestingC）they need not turn back to watch the lightsD）they succeeded in "switching on" the lightsPassage 7The digital revolution, as exemplified by the Internet and electronic commerce, has shaken marketing practices to their core. In a recent paper, Wharton's Jerry Wind, director of the SEI Center for Advanced Studies in Management, and co-author Vijay Mahajan, a marketing professor at the College of Business Administration of the University of Texas at Austin, examine the impact of digital marketing on concepts like pricing, when customers can propose their own prices (), or buyersand sellers can haggle independently in auctions ().The paper provides an overview of some of the emerging realties and new rules of marketing in a digital world, and outlines what the new discipline of marketing may look like in the early part of the new century.To begin with, say the authors, the rapid-fire growth of the Internet is helping to drive changes. "It is not just our computers that are being reprogrammed; it is customers themselves, " says Wind. "These emerging cyber consumers are like an alien race that have landed in the midst of our markets. They have different expectations and different relationships with companies from which they purchase products and services. "For one thing, cyber consumers expect to be able to customize everything —from the products and services they buy and the information they seek, to the price they are willing to pay. And with digital technology opening new channels for gaining information, they are more knowledgeable and demanding than previous consumers.Digital customers can also sort products based on any desired attribute, price, nutritional value, or functionality, and they can easily obtain third-party endorsements and evaluations, tapping the experience of other users. "Companies that cannot meet their demands and expectations will be at a loss, " says Wind.4．The passage was most likely to be taken from ________.A）an overview of a paper B）an introduction to a book C）a book on digital revolution D）a paper discussing digital revolution5．From the third paragraph, we can infer that ________.A）the customers are also reprogrammed by computersB）e-business companies need be more knowledgeable about cyber consumers C）cyber consumers are a group of strange peopleD）cyber consumers came from outer space6．Compared with traditional customers, the emerging cyber consumers ________. A）are more difficult to satisfy B）have less knowledge about businessC）have more problems with prices D）are less willing to buy products and services7．In the last paragraph, what Wind said means ________.A）digital consumers' decision to buy depends largely on others' evaluationB）it will be more and more difficult for companies to earn profit in e-businessC）most of the companies in e-business are at a lossD）companies should try their best to meet the digital consumers' demands and expectations。

人工智能会使大脑退化吗专四英语作文
人工智能会使大脑退化吗专四英语作文全文共3篇示例，供读者参考篇1Will Artificial Intelligence Cause Brain Degeneration?As technology continues its rapid advancement, artificial intelligence (AI) has become increasingly ubiquitous in our daily lives. From virtual assistants like Siri and Alexa to self-driving cars and advanced robotics, AI is transforming the way we live, work, and interact with the world around us. However, amid this technological revolution, a concerning question arises: will the widespread adoption of AI lead to a decline in our cognitive abilities and ultimately cause brain degeneration?To understand the potential impact of AI on our brain functions, we must first grasp the fundamental role that cognitive activities play in maintaining and enhancing our mental faculties. The human brain is a remarkable organ, possessing an incredible capacity for adaptability and growth, a phenomenon known as neuroplasticity. Engaging in cognitively demanding tasks, such as problem-solving, critical thinking, and memory exercises, stimulates the formation of new neuralconnections and strengthens existing ones, thereby enhancing our cognitive abilities.With the advent of AI, there is a growing concern that we may become overly reliant on these advanced systems, leading to a reduction in the cognitive demands placed on our brains. As AI algorithms become increasingly adept at performing tasks that were once exclusively within the realm of human intelligence, we may find ourselves outsourcing more and more cognitive functions to these systems, potentially resulting in a lack of mental stimulation and ultimately, brain degeneration.One area of particular concern is memory. AI-powered virtual assistants and search engines have made it easier than ever to access and retrieve information, reducing the need for us to actively engage in memorization and recall. While this convenience is undeniably beneficial in many aspects of our lives, it may also lead to a decline in our ability to store and retrieve information from our own memory banks, potentially weakening the neural pathways associated with these processes.Additionally, AI-driven automation and decision-making systems could potentially diminish our problem-solving and critical thinking skills. As we increasingly rely on these systems to handle complex tasks and make decisions for us, we maybecome complacent and fail to exercise the cognitive processes that were once essential for navigating challenges and solving problems.However, it is important to note that the impact of AI on our brain functions is not necessarily a one-way street. Just as AI could potentially lead to cognitive decline, it could also serve as a powerful tool for enhancing our mental abilities. For instance, AI-powered educational technologies and brain-training applications could provide personalized and adaptive learning experiences, challenging our minds in novel ways and stimulating the growth of new neural connections.Moreover, the integration of AI into fields such as neuroscience and cognitive research could lead to groundbreaking discoveries and advancements in our understanding of the human brain, potentially enabling us to develop more effective strategies for maintaining and enhancing our cognitive abilities.Ultimately, the question of whether AI will cause brain degeneration is a complex one, with arguments on both sides. While the potential risks of cognitive decline due to over-reliance on AI cannot be ignored, it is essential to approach this issue with a balanced perspective. By actively engaging with AItechnologies in a mindful and responsible manner, we can harness their potential benefits while mitigating potential negative impacts on our cognitive abilities.One way to strike this balance is through education and awareness. Incorporating AI literacy into curricula at all levels of education can equip individuals with the knowledge and skills necessary to navigate the AI-driven world while maintaining a healthy balance between technology and cognitive engagement. This could involve teaching critical thinking and problem-solving strategies, encouraging active learning and memorization techniques, and promoting a deeper understanding of the principles underlying AI systems.Furthermore, fostering a culture of lifelong learning and cognitive enrichment can help counteract the potential negative effects of AI on our brain functions. Engaging in activities that challenge our minds, such as reading, puzzles, learning new skills, and participating in intellectually stimulating hobbies, can help maintain and strengthen our cognitive abilities, regardless of our reliance on AI technologies.In addition, it is imperative that we approach the development and implementation of AI systems with a strong emphasis on ethical considerations and human-centric designprinciples. By ensuring that AI technologies are developed and deployed in a manner that respects human agency and autonomy, we can mitigate the risk of excessive dependence and cognitive complacency.As we navigate this era of unprecedented technological advancement, it is crucial that we remain vigilant and proactive in safeguarding our cognitive abilities. While AI undoubtedly holds immense potential for enhancing various aspects of our lives, we must not lose sight of the fundamental importance of maintaining and nurturing our innate human intelligence.In conclusion, the relationship between AI and brain degeneration is a complex and multifaceted issue that requires careful consideration and a balanced approach. While the risks of cognitive decline due to over-reliance on AI should not be dismissed, the potential benefits of AI in enhancing our cognitive abilities and advancing our understanding of the human brain should also be recognized. By embracing a mindful and responsible integration of AI into our lives, fostering a culture of lifelong learning, and prioritizing ethical and human-centric design principles, we can harness the power of AI while safeguarding the integrity and vitality of our cognitive abilities.篇2Will AI Cause Brain Degeneration?The rapid development of artificial intelligence (AI) has sparked concerns about its potential impact on human cognition. Some argue that our reliance on AI technologies could lead to a decline in mental capacities, ultimately causing our brains to degenerate. As a student facing the challenges of the modern world, I find this topic particularly relevant and worth exploring.On one hand, the convenience and efficiency offered by AI technologies are undeniable. From voice assistants that can answer our queries to recommendation algorithms that curate personalized content, AI has seamlessly integrated into our daily lives. The ability to outsource tasks to these intelligent systems could potentially reduce the cognitive load on our brains, allowing us to conserve mental energy for more demanding endeavors.However, there is a valid concern that this reliance on AI could lead to a gradual atrophy of our cognitive abilities. Just as muscles can weaken from lack of use, our brains may lose their sharpness if we become too dependent on AI for tasks that traditionally challenged our problem-solving and critical thinking skills.One area where this potential degeneration could manifest is in our ability to navigate and orient ourselves in physical spaces. With the advent of GPS and navigation apps, many of us have become accustomed to relying on these technologies to guide us through unfamiliar territories. While convenient, this dependence could potentially weaken our innate sense of direction and spatial awareness, skills that our ancestors had to hone for survival.Similarly, the proliferation of search engines and information retrieval systems has made it easier than ever to access vast amounts of knowledge at our fingertips. While this accessibility is undoubtedly valuable, it could also diminish our motivation to commit information to memory. The ability to instantly look up facts and figures may lead to a decline in our capacity for memorization and recall, cognitive functions that were once essential for academic and professional success.Moreover, the algorithms behind many AI systems are designed to cater to our preferences and biases, creating personalized echo chambers that reinforce our existing beliefs and perspectives. This could potentially stunt the development of critical thinking skills, as we become less exposed to diverse viewpoints and challenging ideas that would traditionallyprompt us to question our assumptions and broaden our perspectives.On the other hand, proponents of AI argue that these technologies can actually enhance our cognitive abilities if utilized correctly. For instance, AI-powered educational tools can provide personalized learning experiences tailored to individual strengths and weaknesses, potentially improving our ability to acquire and retain knowledge more effectively.Additionally, the automation of routine and repetitive tasks could free up mental resources for more complex and creative endeavors, allowing us to focus our cognitive capacities on higher-order thinking and problem-solving. AI systems could also augment our decision-making processes by providing data-driven insights and analyses, potentially mitigating the effects of cognitive biases and emotional influences.Ultimately, the impact of AI on our cognitive abilities will likely depend on how we choose to integrate these technologies into our lives. If we become overly reliant on AI as a crutch, outsourcing tasks that would traditionally challenge and exercise our brains, then there is a risk of cognitive degeneration. However, if we approach AI as a tool to augment and enhance our existing abilities, leveraging its strengths while activelyengaging our own cognitive faculties, then it could potentially amplify our mental capacities.As a student navigating the complexities of the modern world, I believe it is essential to strike a balance between embracing the conveniences of AI and maintaining a commitment to exercising our cognitive abilities. We should remain vigilant about the potential risks of over-reliance on these technologies and actively seek opportunities to challenge our minds through activities that promote problem-solving, critical thinking, and lifelong learning.Furthermore, educational institutions and policymakers should prioritize the development of curricula and programs that foster cognitive resilience in the face of technological advancements. This could involve incorporating activities that strengthen skills such as memorization, spatial awareness, and analytical reasoning, while also promoting digital literacy and responsible use of AI technologies.In conclusion, the question of whether AI will cause brain degeneration is a complex one with valid arguments on both sides. While the convenience and efficiency of AI technologies are undeniable, we must remain mindful of the potential risks of over-reliance and strive to maintain a balance betweenleveraging these tools and actively exercising our cognitive abilities. By adopting a thoughtful and measured approach to AI integration, we can harness its potential while preserving and enhancing our mental capacities for generations to come.篇3Will AI Cause Brain Degeneration?The rapid advancement of artificial intelligence (AI) technology has ignited a heated debate about its potential impact on human cognitive abilities. As AI systems become increasingly sophisticated, capable of performing tasks that were once solely within the human domain, concerns have arisen that our reliance on these technologies may lead to a decline in our brain's capabilities. In this essay, I will explore the arguments on both sides of this contentious issue and ultimately conclude that while AI does present some risks, it is unlikely to cause widespread brain degeneration if used judiciously.On one hand, proponents of the brain degeneration hypothesis argue that our growing dependence on AI could result in a phenomenon akin to the atrophy of unused muscles. Just as our physical muscles weaken when we become sedentary, the cognitive muscles of our brains may deteriorate if we offloadtoo many mental tasks onto AI systems. They contend that by outsourcing cognitive functions like memory, problem-solving, and decision-making to AI, we may lose the ability to exercise and maintain these crucial mental faculties.This line of reasoning is bolstered by numerous examples of how technology has already impacted our cognitive abilities. The advent of calculators and spell-checkers, for instance, has arguably diminished our ability to perform mental arithmetic and spelling tasks. Similarly, the ubiquity of GPS navigation systems has reduced our reliance on mental mapping and spatial reasoning skills. Proponents argue that AI poses an even greater threat, as it has the potential to automate increasingly complex cognitive tasks, leaving our brains underutilized and susceptible to degeneration.Moreover, there are concerns that the convenience and efficiency offered by AI could foster a culture of intellectual laziness and complacency. If we become accustomed to relying on AI for mental tasks, we may lose the motivation to challenge ourselves and develop our cognitive abilities, leading to a gradual erosion of our mental capabilities.On the other hand, opponents of the brain degeneration hypothesis argue that AI is a tool, and like any tool, its impact onour cognitive abilities depends on how we choose to use it. They contend that AI has the potential to augment and enhance our mental capabilities rather than diminish them. By offloading routine and tedious tasks to AI systems, we can free up cognitive resources to focus on higher-order thinking, creativity, and problem-solving.Furthermore, AI can serve as a powerful educational tool, providing personalized learning experiences and adaptive curricula tailored to individual needs and learning styles. This could potentially enhance our cognitive development and foster a deeper understanding of complex concepts, rather than promoting intellectual atrophy.Opponents also argue that the human brain is remarkably plastic and adaptable, capable of reorganizing and rewiring itself in response to new challenges and experiences. As we interact with AI systems, our brains may develop new cognitive pathways and strategies to integrate and leverage these technologies effectively. This process of cognitive adaptation could ultimately strengthen and diversify our mental capabilities, rather than causing degeneration.Additionally, the development of AI is not a one-way street; it is a collaborative process that requires human intelligence andoversight. By actively engaging with AI systems, we can continually challenge ourselves to understand and improve these technologies, fostering a symbiotic relationship that stimulates cognitive growth and innovation.In my opinion, the truth likely lies somewhere between these two extremes. While the potential for brain degeneration due to excessive reliance on AI cannot be dismissed entirely, it is unlikely to occur on a widespread scale if we adopt a balanced and judicious approach to integrating AI into our lives.The key lies in striking a careful balance between leveraging the benefits of AI while still engaging in activities that exercise and stimulate our cognitive faculties. Rather than outsourcing all mental tasks to AI, we should selectively offload routine and repetitive tasks, freeing up mental resources to focus on more complex and creative endeavors. This approach could potentially enhance our cognitive abilities by allowing us to concentrate on higher-order thinking and problem-solving, while still maintaining and exercising our fundamental cognitive skills.Moreover, it is crucial to foster a culture of lifelong learning and intellectual curiosity, where we continually challenge ourselves to acquire new knowledge and skills, both with and without the aid of AI. By embracing a growth mindset andactively seeking opportunities for cognitive enrichment, we can counteract the potential risks of complacency and intellectual laziness.Education and awareness also play a vital role in mitigating the risks of brain degeneration. By understanding the potential pitfalls of overreliance on AI, we can develop strategies and best practices for integrating these technologies in a responsible and cognitively-enriching manner. This includes promoting media literacy, critical thinking skills, and a healthy skepticism towards the outputs of AI systems, ensuring that we remain actively engaged and discerning users.In conclusion, while the potential for AI to cause brain degeneration should not be dismissed entirely, it is a risk that can be effectively mitigated through a balanced and thoughtful approach to integrating these technologies into our lives. By selectively leveraging the benefits of AI while actively engaging in cognitively-stimulating activities, fostering a culture of lifelong learning, and promoting responsible AI usage through education and awareness, we can harness the power of AI to enhance and augment our cognitive abilities, rather than diminish them.。

1、举例说明搜索
3、结合自己的专业和学习，从四川师范大学图书馆 网站上所列示的数据库中各查找一篇文献。
• • • • 检索目标：建筑工程造价 CNKI 检索点：全文 检索词：建筑工程造价 下载题目：建筑工程造价控制系统的设计与实现 作者：马文翠（学号：200792311003） 学校：电子科技大学，软件工程， 2009，硕士
1、举例说明搜索引擎中filetype、site、双引号这三个高级检索语法的功能。
(1) filetype的作用是专业文档搜索。有价值的资料在网络上并非是普通的网页，而是以 Word、Pxcel、Powerpoint）、Adobe PDF文档、RTF文档进行 了全文搜索。要搜索这类文档，很简单，在普通的查询词后面，加一个“filetype：”文档类型限定。 “Filetype:”后可以跟以下文件格式：DOC、XLS、PPT、PDF、RTF、ALL。其中，ALL表示搜索所有这些文件 类型例如，查找尚伟常关于科技创新方面的经济学论文。“科技创新尚伟filetype:doc”，点击结果标题，直 接下载该文档，也可以点击标题后的“HTML版”快速查看该文档的网页格式内容。。 (2) （2）site的作用把搜索范围限定在特定站点中。有时候，如果知道某个站点中有自己 需要找的东西， 就可以把搜索范围限定在这个站点中，提高查询效率。使用的方式，是 在查询内容的后面，加上“site:站 点域名”。 例如，电影天堂下载电影不错，就可以这样查询： msn site: 注意，“site:”后面跟的站点域名，不要带“http://”；另外，site:和站点名之间，不要 带空格。 (3) 减号的作用是要求搜索结果中不含特定查询词。如果您发现搜索结果中，有某一类网页 是不希望看见的， 而且，这些网页都包含特定的关键词，那么用减号语法，就可以去除所有这些含有特定关键词的网页。例 如水浒传，希望是关于小说方面的内容，却发现很多关于电视剧方面的网页。那么就可以这样查询：水浒 传 -电视剧。 (4) 双引号， 可能是拆 达到这种效果。 例如，搜索 四川师范大学 ，如果不加双引号，搜索结果被拆分，效果不是很好，但加上 双引号后，“四川师范大学”，获得的结果就全是符合要求的了。 (5) Inurl的作用是把搜索范围限定在url链接中。网页url中的某些信息，常常有某种 有价值的含义。于是， 如果对搜索结果的url做某种限定，就可以获得良好的效果。实现的方式，是用“inurl:”，后跟需要在url中 出现的关键词。 例如，找关于坦克世界的使用技巧，可以这样查询：坦克世界 inurl:技巧 上面这个查询串 中的“坦克世界”，是可以出现在网页的任何位置，而“技巧”则必须出现在网页url中。

Search Engine Architecture
• A software architecture consists of software components, the interfaces provided by those components, and the relationships between them
– Tokenizer recognizes “words” in the text
• must consider issues like capitalization, hyphens, apostrophes, non-alpha characters, separators
Text Transformation
• Parser
– Processing the sequence of text tokens in the document to recognize structural elements
• e.g., titles, links, headings, etc.
– describes a system at a particular level of abstraction
• Architecture of a search engine determined by 2 requirements
– effectiveness (quality of results) and efficiency (response time and throughput)
信息检索课程中的英文简称
信息检索课程中的英文简称Information Retrieval Course: An In-Depth Exploration.Information retrieval, commonly abbreviated as IR, is a crucial field in computer science that deals with the retrieval of information from large collections of unstructured or semi-structured data. It finds its applications in various domains, including libraries, e-commerce, search engines, and more. In this article, we delve into the intricacies of information retrieval, its importance, and the techniques used in this domain.1. Introduction to Information Retrieval.Information retrieval is the process of obtaining relevant information from a large, often unstructured, collection of data. It involves techniques such as indexing, searching, and ranking to ensure that the most relevant information is presented to the user. The goal is toprovide accurate and timely information to meet the user'sinformation needs.2. Core Components of Information Retrieval.Indexing: Indexing is the process of creating a data structure, such as an inverted index, that maps terms (keywords) to the locations (documents) where they appear. This allows efficient retrieval of documents containing specific terms.Searching: Searching involves the user submitting a query, which is then processed and compared against the index to retrieve relevant documents. Queries can be simple keywords or complex expressions.Ranking: Ranking algorithms determine the order in which retrieved documents are presented to the user. Relevance, popularity, and recency are common factors considered in ranking.3. Types of Information Retrieval Systems.Boolean Retrieval: Boolean retrieval systems allow users to specify search queries using Boolean operators (AND, OR, NOT) to combine terms and filter results.Vector Space Models: These models represent documents and queries as vectors in a high-dimensional space. Relevance is determined by measuring the similarity between these vectors.Probabilistic Models: Probabilistic models estimate the probability of a document being relevant to a given query. They consider factors like term frequencies and document lengths.Learning-to-Rank (L2R) Models: These models use machine learning techniques to learn the ranking function based on training data. They aim to optimize ranking metrics like mean reciprocal rank (MRR) or normalized discounted cumulative gain (NDCG).4. Challenges in Information Retrieval.Semantic Gap: The semantic gap refers to the mismatch between the user's information need and the representationof information in the system. Addressing this gap requires techniques like latent semantic indexing or word embeddings.Scalability: As data collections grow, it becomes challenging to maintain and query the index efficiently. Distributed retrieval systems and近似算法can help address scalability issues.User Intent Understanding: Understanding the trueintent behind a user's query is crucial for accurate retrieval. Techniques like query reformulation and user profiling can aid in understanding user intent.5. Applications of Information Retrieval.Search Engines: Search engines are the most visible application of information retrieval, serving billions of queries daily. They use a combination of IR techniques to provide relevant search results.E-commerce: E-commerce platforms rely on IR to help users find products or services that meet their needs. This involves searching product descriptions, user reviews, and more.Libraries and Archives: Libraries and archives use IR systems to catalog and retrieve books, documents, and other materials. These systems often incorporate metadata and faceted search to enhance retrieval accuracy.Question Answering Systems: Question answering systems aim to provide direct answers to user queries, often by analyzing a large corpus of text to extract relevant information.6. Future Trends in Information Retrieval.Semantic Retrieval: As the focus shifts towards understanding the true meaning of queries and documents, semantic retrieval techniques like entity linking and semantic role labeling will become increasingly important.Multimodal Retrieval: With the increasing availability of multimedia content, there is a growing need for systems that can handle text, images, audio, and video simultaneously.Personalized Retrieval: Techniques like user profiling and collaborative filtering will play a crucial role in personalizing search results based on user preferences and behavior.Interactive Retrieval: Systems that allow users to interactively refine their queries or provide feedback on search results will improve retrieval accuracy and user satisfaction.In conclusion, information retrieval is a crucial field that powers many of the technologies we rely on daily. It involves complex techniques and algorithms to ensure accurate and timely information delivery. As data volumes continue to grow and user needs become more sophisticated, IR research will focus on addressing challenges like the semantic gap, scalability, and user intent understanding.Future trends like semantic retrieval, multimodal retrieval, personalized retrieval, and interactive retrieval will further enhance the capabilities of IR systems and improve user experiences.。
