To bridge the gap between promise and practice, Jann Spiess, an associate profes- sor at Stanford Graduate School of Business, is exploring how algorithms(算法) can be designed to most ef- fectively support—rather than replace—human decision-makers. 　　“We don't have much work yet that takes the design of the human-AI interface really seriously,” says Spiess. “Our debate about AI and the capabilities of AI is really misplaced, because it's all about ‘Is AI better than the human?’,” he continues, “and I think instead we should be asking, ‘What are the com- plementary(互补的) uses of AI?’” 第1讲　描述运动的基本概念 　　If users rely too heavily on an algorithm, they may ignore relevant context or information the algorithm may not know. On the other hand, if users consider recommendations overly complex or irrelevant, they may dismiss them altogether, ________ any advantage algorithmic recommendations may provide. 　　“Therefore, the best algorithm should take into account how a human will interact with the informa- tion it provides,” Spiess says. In a recent paper, Spiess outlines a conceptual(概念的) design framework modeling how humans respond to algorithmic recommendations—and presents a different way to build AI tools. This way is known as complementarity. 　　The researchers tested different recommendation strategies in an experiment, where participants made 2 5 hiring decisions furnished with different levels of algorithmic assistance. People using a complementary algorithm—which offered selective recommendations in cases where a human was likely to be uncertain or incorrect—made the most accurate decisions, outperforming those using a purely predictive algorithm and forgoing 第1讲　描述运动的基本概念 those using no algorithmic support. 　　It's an encouraging result. “There's much promise around AI improving decisions,” says Spiess, who's particularly interested in applications that affect how services are allocated (分配) in resource-limited envi- ronments, such as placing teachers in underserved school districts with limited budgets. “If we could use algorithms to improve resource allocation, there are many high-value use cases in areas where we don't have ready or clear solutions,” he says. 1.What is the main issue with current AI debates according to Spiess? A.Ignoring the potential of AI. B.Overemphasis on AI's superiority. C.Misunderstanding AI's purpose. D.Lack of focus on AI's efficiency. 第1讲　描述运动的基本概念 2.What does the underlined word “forgoing” in paragraph 3 mean? A.Abandoning.　　B.Stressing.　　C.Admitting.　　D.Assessing. 3.What does Spiess think is the key to effective AI design? A.Enhancing algorithmic complexity. B.Reducing human dependence on AI. C.Considering human-AI interaction. D.Improving AI's independent capability. 4.What did the experiment on hiring decisions show? A.Predictive algorithms were the most helpful. B.Human judgment alone was the most accurate. C.No algorithmic support was completely the best. D.Complementary algorithms were highly effective. 第1讲　描述运动的基本概念 语篇解读    本文是一篇议论文。文章主要探讨了如何将人工智能(AI)有效地融入我们的生活和工 作。 【高频词汇】    1.ignore v.忽略    2.relevant adj.相关的    3.complex adj.复杂的　complexity n.复杂性 4.dismiss v.不予考虑;解雇    5.accurate adj.准确的 6.outperform v.超过,胜过    7.efficiency n.效率 【熟词生义】    1.take off熟义:脱掉,起飞　生义:突然大受欢迎,迅速流行    2.present熟义:n.礼物adj.当 前的　生义:v.提出    3.promise熟义:v.& n.承诺　生义:n.(获得成功的)迹象,吉兆 【差距词汇】    1.interface n.界面;接口 v.接合,连接 2.underserved adj.未得到足够帮助(或产品、服务)的 第1讲　描述运动的基本概念 长难句 第1讲　描述运动的基本概念 1.B　细节理解题。根据第二段中的“Our debate about AI...all about ‘Is AI better than the human?’... instead we should be asking, ‘What are the complementary uses of AI?’”可知,Spiess认为关于AI的辩 论主要问题在于过于强调AI的优越性,而没有关注其互补性用途。故选B。 2.A　词义猜测题。根据第三段可知,“用户如果过于依赖算法,他们可能会忽略算法可能未知的相关 背景或信息。另一方面,用户如果认为建议过于复杂或不相关,就可能会完全忽略这些建议, ______这 些算法建议可能提供的任何优势”。代入选项,A项“Abandoning(放弃).”与语境中“完全忽略这些 建议后放弃这些算法建议可能提供的任何优势”的顺承逻辑完全吻合。故选A。 3.C　细节理解题。根据第四段第一句可知,Spiess认为有效的人工智能设计的关键在于考虑人类与人 工智能的交互。故选C。 4.D　推理判断题。根据第五段的研究结果“People using a complementary algorithm...made the most accurate decisions, outperforming those...algorithmic support.”可推知,关于招聘决策的实验表明互补性 算法非常有效。故选D。 　　     第1讲　描述运动的基本概念 Ⅱ.七选五   [2026山东青岛黄岛区期中] 　　The roll-out of 5G technology is set to transform not only the way we live but also the modes of work, promising innovative changes across societies. 　1　 It enables smooth 4K/8K video streaming, instant downloads of large files, and better online gaming experiences that redefine digital entertainment. 　　Beyond entertainment, 5G has significant implications for critical industries such as healthcare and transportation in the new era. For example, surgeons could perform complex remote surgeries with minimal delay. This ensures precise control even from thousands of miles away. Self-driving cars will communicate with each other and traffic infrastructure(基础设施) in real time, facilitating people's daily travel. 　2　 　　However, the change to 5G is not without challenges. 　3　 Additionally, some rural areas may face 第1讲　描述运动的基本概念 delays in accessing this technology due to the high cost of building infrastructure like small cell towers and fiber-optic(光纤) networks, widening the digital divide temporarily. 　　　4　 The Internet of Things (IoT) will greatly gain from 5G, as it can support billions of connected devices at the same time. Smart cities, powered by 5G, could improve traffic flow via intelligent signals, re- duce energy consumption by auto-adjusting public services, and enhance public safety with real-time obser- vation and rapid emergency response systems. 　　There is a tendency that governments and companies worldwide are investing heavily in 5G infrastruc- ture to seize these opportunities. As more devices—from smartphones to automatic vehicles—become inter- connected, the demand for faster, more reliable, and short-delay networks will only increase, making 5G the cornerstone of the next digital revolution. 　5　 第1讲　描述运动的基本概念 A.This greatly cuts risks through instant data exchange. B.Despite these problems, the potential benefits are enormous. C.Moreover, 5G can support the development of the healthcare industry. D.4G networks will soon become outdated as 5G becomes the mainstream. E.Many people are concerned about the health risks associated with 5G radiation. F.One major advantage is its short delay, which reduces the slow response in communication. G.As it matures, its extensive impacts will bring about a more connected and intelligent world. 1.______ 2.______ 3.______ 4.______ 5.______ 　G     　B     　E     　A     　F     第1讲　描述运动的基本概念 语篇解读　本文是一篇说明文。文章介绍了5G技术即将给娱乐、医疗、交通、智慧城市等带来的革 新好处,同时指出健康担忧、农村覆盖成本等挑战。 【高频词汇】    1.transform v.使改变,使转换 2.innovative adj.创新的,革新的    3.precise adj.准确的;精确的    4.potential adj.潜在的;可能的    5.benefit n.益处    6.(be) associated with与……相关 【熟词生义】　promise熟义:v.承诺n.诺言　生义:v.预示,使很可能 【差距词汇】    1.cell tower手机信号塔    2.auto-adjusting adj.自动调节的    3.interconnected adj.相互连 接的    4.cornerstone n.基石;基础 1.前文总述 5G的变革性影响,后文列举 5G 在数字娱乐领域的应用优势。由此可知,选项F (一大优势是 其短暂的延迟,可减少通信中的缓慢反应。)可承接前文话题,引出后文具体优势,其中which 引导的定 第1讲　描述运动的基本概念 语从句解释“short delay”的作用,呼应后文“instant downloads”,构成“总述→过渡→细节”的逻辑。故选F。 2.由前文“自动驾驶汽车会与彼此及交通基础设施进行实时通信,为人们的日常出行提供便利”可知, 选项A(通过即时数据交换,这能大幅降低风险。)符合语境,其中“This”指代“实时通信”,“cuts risks” 是对“facilitating people's daily travel”的补充,构成“具体应用→细节延伸”的逻辑。故 选A。 3.根据主旨句“However, the change to 5G is not without challenges.”和后文的“Additionally, some ru- ral areas may face delays...”可知,设空处应为具体挑战,因此选项E(许多人担心与5G辐射相关的健康风 险。)符合语境,其中“concerned about the health risks”与后文“some rural areas may face delays...”均 为“challenges”的具体内容,通过“Additionally”形成逻辑递进。故选E。 第1讲　描述运动的基本概念 4.第三段阐述5G推广的挑战,第四段阐述5G对物联网、智慧城市的巨大价值。由此可知,选项B(尽管 存在这些问题,但潜在的好处是巨大的。) 可承上启下,其中“these problems”指代前文的“health risks”和“some rural areas may face delays...”,“potential benefits”引出后文的物联网、智慧城市优 势,构成“挑战→过渡→优势”的逻辑。故选B。 类比启发　　七选五中,如前、后段落为“问题→优势”“否定→肯定”的内容,中间段的段首设空处 可优先考虑含 “Despite/However/Yet”等的过渡句。 第1讲　描述运动的基本概念 5.根据前文“随着更多的设备——从智能手机到自动驾驶交通工具——实现互联互通,人们对速度更 快、可靠性更高、时延更低的网络需求只会增长,这使5G成为下一场数字革命的基石。”可知,G项 (随着它的成熟,其广泛影响将带来一个更加有联系和智能的世界。)与“cornerstone of the next digital revolution”呼应,“As it matures”承接“the demand for...will only increase”,且“a more connected and intelligent world”升华首段第一句,是主旨的总结与延伸。故选G。 第1讲　描述运动的基本概念 Ⅲ.完形填空   [2025安徽江淮名校期中联考] 　　In my grandparents' era, the question of whether to repair or replace an item was irrelevant.
