Several physicists argued that the science underlying machine learning was not actually physics.“I like machine learning and artificial neural networks as much as the next person, but it's hard to see that this is a physics discovery.” said Jonathan Pritchard, an astrophysicist at Imperial College London. Not everyone was troubled, however.“Hopfield and Hinton's research brought together physics, math, computer science and neuroscience，” said Matt Strassler, a theoretical physicist at Harvard University. “In that sense, it belongs to all of these fields.” Anil Ananthaswamy, a science writer based in Berkeley, pointed out that although the research cited by the Nobel committee might not be theoretical physics in the purest sense, it is rooted in techniques and concepts from physics, such as energy.But Anil also added, the connection with physics became more delicate in upcoming developments in machine learning, particularly in techniques that made neural networks easier to train. Computer science seemed to be completing its Nobel takeover the day after the physics prize announcement, when Demis Hassabis and John Jumper won half of the chemistry Nobel.The prize was a recognition of the innovative force of AI, but also of the steady gathering of knowledge in structural and computational biology.“It wasn't just that we went to work, pressed the AI button, and then all went home，” Jumper said.“It was really an iterative (迭代的) process where we developed, we did research, we tried to find the right kind of combinations between what the community understood about proteins and how we build those insights into our architecture.” Since they were first awarded in 1901, the Nobels have often highlighted the impact of research on society, and have rewarded practical inventions, not only pure science.In this respect, this year's prizes are not outliers. 语篇解读：本文是一篇新闻报道。文章主要讲述了2024年诺贝尔奖将奖项授予人工智能领域引发的学术争议，以及诺贝尔奖评选标准中实用性与理论性平衡的探讨。 1．How did Jonathan Pritchard react to the 2024 Nobel Prize in Physics? A．He praised the organizers. B．He doubted the discovery. C．He congratulated the winners. D．He questioned the classification. √ 解析：推理判断题。根据第二段中“I like machine learning and artificial neural networks as much as the next person, but it's hard to see that this is a physics discovery.”可知，Jonathan Pritchard作为几位物理学家之一，认为机器学习背后的科学实际上不是物理学，他觉得很难将其视为一项物理学发现。也就是说，他就该成果在物理学奖这一分类上提出了质疑。 2．What can we learn from paragraph 3? A．Hopfield and Hinton's research is a combination of multiple fields. B．The Nobel committee only considers pure theoretical physics for awards. C．The connection between physics and machine learning is irrelevant. D．The future developments in machine learning will completely eliminate physics. √ 解析：推理判断题。根据第三段中“‘Hopfield and Hinton's research brought together physics, math, computer science and neuroscience，’ said Matt Strassler, a theoretical physicist at Harvard University.”可知，Matt Strassler认为Hopfield和Hinton的研究融合了物理学、数学、计算机科学和神经科学。也就是说，他们的研究融合了多个领域的知识。 3．What did Jumper owe their achievement to? A．The AI-powered iterative research. B．The innovative research in architecture. C．The community-driven research process. D．The use of AI research for quick answers. √ 解析：细节理解题。根据第四段中“‘It wasn't just that we went to work, pressed the AI button, and then all went home，’ Jumper said.‘It was really an iterative process where we developed, we did research, we tried to find the right kind of combinations between what the community understood about proteins and how we build those insights into our architecture.’”可知，Jumper表示他们的成果并非只是简单地使用人工智能，而是一个迭代的过程，在这个过程中他们不断发展、研究，试图找到关于蛋白质的已有认知和如何将这些见解融入架构之间的正确组合方式。这强调了人工智能驱动的迭代研究过程对他们取得成就的重要性。 4．Which of the following questions does the text mainly address? A．Who won this year's Nobels using AI? B．How do this year's Nobels reflect AI's role? C．Why are scientists against this year's Nobels? D．What's the outcome of this year's Nobels debate? √ 解析：主旨大意题。文章开篇指出 2024 年诺贝尔奖在物理学奖和化学奖方面肯定了人工智能的变革性力量，接着讲述了不同人对将与人工智能相关的成果授予诺贝尔奖的不同看法，最后强调诺贝尔奖常常重视研究对社会的影响。整体围绕今年诺贝尔奖如何体现人工智能的作用展开讨论。故B项(今年的诺贝尔奖如何体现人工智能的作用？)准确地概括了文章的主要内容。 (二)语法填空 In Guangxi Zhuang Autonomous Region, plant leaves used to be wasted will now be processed into cattle feed at local feed factories.Similarly, 5 industrial model of recycling crops into silage (青贮饲料) has been developed recently in Hunan.In fact, both of the 6 (change) are due to a new technology — biological feed. Biological feed is the general term for a new feed resource, 7 is safe and of high quality.It is developed by means of modern bio-technology such as genetic (基因的) engineering.Nowadays, China's feed industry is developing 8 (rapid)．Biological feed enjoys a wide range 9 materials.It is renewable and less expensive than special feed, greatly reducing environmental pollution and 10 (promote) the long-term development of the animal feed industry.“Promoting biological feed technology 11 (be) a certain direction and measure 12 (ensure) the high-quality development of the feed industry，” said an official of the Ministry of Agriculture and Rural Affairs. China now attaches great 13 (important) to the development of the industry.To better promote the standardization of the industry, the country has taken 14 (effect) measures from the viewpoints of the management system and technical standards. 语篇解读：本文是一篇说明文。文章主要介绍了可以将农作物废料回收加工成饲料的新技术——生物饲料，以及它的优点。 5．an　考查冠词。此处泛指一种工业模式，且industrial以元音音素开头，应用不定冠词an。 6．changes　考查名词复数。根据“both of”可知，空处应用复数形式。故填changes。 7．which　考查定语从句。分析句子可知，该空引导非限制性定语从句，先行词是a new feed resource，指物，在从句中作主语，应用关系代词which。 8．rapidly　考查副词。空处修饰动词develop，应用副词作状语。故填rapidly。 9．of　考查介词。a wide range of是固定短语，意为“范围广泛的”。故填of。 10．promoting　考查非谓语动词。此处应用非谓语动词作状语，且It指代上文Biological feed，promote和逻辑主语It之间是主动关系，故填promoting。 11．is　考查时态和主谓一致。本句讲述客观事实，时态应用一般现在时，且动名词短语作主语，谓语应用单数形式。故填is。 12．to ensure　考查非谓语动词。此处应用不定式形式作名词短语direction and measure的后置定语。故填to ensure。 13．importance　考查名词。attach importance to是固定短语，意为“重视”。故填importance。 14．effective　考查形容词。空处修饰名词measures，应用形容词作定语。故填effective。 本课结束 更多精彩内容请登录：www.zghkt.cn $
