TRANSCRIPTImportant Terms and Ideas for Describing Artificial IntelligenceThere are several terms experts use to describe computer systems in the field of artificial intelligence. Recently, the French News Agency (AFP) defined some of the common terms and ideas used in that field. Here is a version for English learners:intelligence n. 智力，智能Artificial intelligence The first term is “artificial intelligence.” When asked what artificial intelligence is, the AI-powered ChatGPT system says that the term means “the simulation of human intelligence in machines that are programmed to think, learn and make decisions”. (Q1) AI’s main quality or characteristic is taking in large amounts of data and then processing it using methods from statistics. AI involves using ideas from many fields including computing, mathematics, languages, psychology, and others. Currently, the technology is being used heavily for investigating health issues, translating human languages, and predicting problems in machine tools and self-driving cars. But AI is affecting many fields of business and industry.simulation n. 模拟，仿真Algorithm A second important term is “algorithm.” (Q2) An algorithm is important to all computer operations. It is a series of steps or instructions followed by a computer program to get a result. Algorithms can give rules for an AI’s behavior, helping it to realize the objectives of computer program developers. Unlike a simple computer program, AI algorithms permit a computer system to “learn” for itself.algorithm n. 算法，运算法则Machine learning A third important term is “machine learning.” Machine learning is one method that researchers have used in their efforts to produce artificial intelligence. Machine learning lets computers learn from data without being directly programmed on what results to produce. In recent years, the field of neural networks has given important results. In a neural network, connections between some nodes are strengthened and others weakened as the system learns and makes changes. Learning can be “supervised.” This means the system learns to put new data into specific groups based on a model. For example, the system could learn to identify spam in an email or other messaging programs. “Unsupervised” learning permits the system to independently discover new areas or ways of doing things. These discoveries in the available data might not have been immediately clear. An example would be letting an online store identify buying trends in sales data. (Q3) “Reinforcement” learning adds a process of repeated trial-and-error. In this process, the system is rewarded based on its outcomes, causing it to learn and improve. One example might be a self-driving vehicle whose objective is to reach its destination as quickly as possible but also safely. That requirement would lead it to learn to stop at red lights although it requires additional time.neural adj. 神经的node n. 节点spam n. 垃圾邮件Deep learning (Q4) Deep learning owes its name to its use of many layers of neural networks. Raw data is examined by each layer in turn at growing levels of abstraction. Geoffrey Hinton received the 2024 Nobel Prize in Physics. Hinton is credited with developing deep learning. Hinton received the prize along with 1980s neural-network developer John Hopfield. Francis Bach, head of France’s SIERRA statistical learning laboratory, said this about deep learning: “The more layers you have, the more complex behavior can become, and the more complex the behavior can be, the easier it is to learn a desired behavior efficiently.” The method might help lead to scientific discoveries.Language models We now turn to large language models (LLMs). These might be the most popular example of generative AI. Large language models’ power tools like OpenAI’s ChatGPT or Google’s Gemini. Such systems are able to write long papers, answer legal questions or even produce a cake recipe based on their statistical models. But the technology is still new. (Q5) LLMs can suffer from “hallucinations” — the creation of content that is false or incorrect.hallucination n. 幻觉，虚构内容Artificial general intelligence A final important term is artificial general intelligence (AGI) — one the big goals of the whole AI field. (Q6) AGI suggests the unrealized dream of a machine able to reproduce all human processes of human thinking. People who push the idea include OpenAI chief Sam Altman and his competitors at Anthropic. They consider such a system to be within reach. The goal is to use large amounts of data and processing power to train LLMs that are increasingly powerful. But critics say that LLM technology has important limits, including its ability to reason. Maxime Amblard, computing professor at France’s University of Lorraine, told AFP last year, “LLMs do not work like human beings.” Amblard added that humans, as flesh-and-blood intelligent beings, are “sense-making machines” with different abilities from today’s computer systems.Part III. KEYQ1. C. 细节题。题目出处：AI’s main quality or characteristic is taking in large amounts of data and then processing it using methods from statistics. 意为：AI的主要特性是接收大量数据并使用统计方法进行处理。因此答案为C。Q2.

What is the primary focus of the recording?A. How to store vegetables to maintain their nutritional value.B. The impact of cooking methods on vegetable nutrition and taste.C. The comparison between raw and cooked vegetables.D. The importance of eating vegetables regardless of preparation. Part II. TRANSCRIPTWhat Is the healthiest way to prepare vegetables?Carlene Thomas is a dietitian, a person who gives advice about healthy foods to eat. When it comes to eating healthy vegetables, Thomas says there are two kinds of people who ask her for advice.dietitian n. 营养学家The first kind wants to know how different cooking methods affect the nutrition in vegetables. The other kind of person wants to know how to eat more vegetables. (Q1) Thomas’ simple answer to both groups is this: The best vegetables are the ones you actually want to eat.Thomas told the Associated Press that many people buy vegetables that they think they will eat. Maybe the produce is popular or someone is bringing attention to it on social media. But then they end up not using it. That means the vegetable gets thrown away after it goes bad.In that case, Thomas said, “It doesn’t matter how you cook them, because if they’re going in the trash, they’re not in your body.”(Q5) However, Thomas said research shows cooking methods do affect nutrition. But it is not as simple as comparing raw, or uncooked, vegetables to cooked ones. Cooking methods can include steaming, roasting, boiling, or sauteing.saute v. 煎，炒So, are raw vegetables healthier than cooked? Not always.When vegetables are cooked with high heat for a long period of time many nutrients break down. However, cooking softens the cell walls in vegetables, making them easier for the body to digest. (Q2) Cooking changes the structure of vegetables which increases what dietitians call bioavailability. This is the body’s ability to use the nutrients in vegetables, Thomas said.bioavailability n. 生物利用度（指身体吸收和利用营养的能力）Cooked food is often more nutritious than raw food. For example, cooked tomatoes release more of the antioxidant lycopene than raw tomatoes, she said. Lycopene is believed to have qualities that prevent cancer.nutritious adj. 有营养的，营养丰富的 antioxidant n. 抗氧化剂lycopene n. 番茄红素Also, cooked carrots have more beta-carotene that can be absorbed by the body. Roasting pumpkins, carrots and sweet potatoes increases available carotenoids. These antioxidants are thought to prevent inflammation in the body.pumpkin n. 南瓜carotenoid n. 类胡萝卜素inflammation n. 炎症Which cooking methods are the healthiest?However, the shorter the cooking time, the more nutrients are kept in the food. That advice comes from Amber Pankonin, a dietitian in the U.S. state of Nebraska.Cooking over boiling water, or steaming, and in a microwave are considered the most nutritious methods. These two methods use little time and require no fat.Another healthy method is blanching. This is when you boil vegetables in water for a minute or two. But not too long. (Q3) Boiling vegetables runs the risk of losing water-soluble nutrients including vitamin C, B1 and folate. Thomas explained the reason boiling is not good for vegetables: The nutrients are “leaching into the water, and you’re tossing out the water.”blanch v. 焯水，焯烫folate n. 叶酸leach v. （液体）过滤，浸出However, you could save the water from boiled vegetables and use it for other purposes, such as soups, or just drink it.What about taste?Dietitians say there is no problem using a small amount of fat. (Q4) Besides making vegetables taste better, a little cooking oil helps the body to absorb fat-soluble vitamins, said Pankonin.That means more vitamin A from squash, carrots, and sweet potatoes; more vitamin D from mushrooms; more vitamin E from bell peppers, leafy greens and asparagus; and more vitamin K from greens, broccoli and onions.squash n. 西葫芦asparagus n. 芦笋broccoli n. 西兰花For pan frying or sauteing, Pankonin suggests cooking with enough oil so the vegetables do not stick to the pan. The amount of oil will depend on the quantity of vegetables and the size of the pan.For roasting, you will likely need more oil. Despite the longer cooking time, roasting will still keep some nutrients and will increase the flavor with the heating of natural sugars.“Flavor is king,” Pankonin said. “I would much rather see people roasting their vegetables and enjoying them.”Part III. KEYQ1. C. 细节题。题目出处：Thomas’ simple answer to both groups is this: The best vegetables are the ones you actually want to eat. 意为：Thomas对这两类人的简单回答是“最好的蔬菜就是你真正愿意吃的蔬菜”。因此C选项正确。Q2. A. 细节题。题目出处为：Cooking changes the structure of vegetables which increases what dietitians call bioavailability. This is the body’s ability to use the nutrients in vegetables. 意为：烹饪会改变蔬菜的结构，从而增加生物利用度，即身体利用蔬菜中营养成分的能力。因此A选项正确。Q3. B. 细节题。题目出处：Boiling vegetables runs the risk of losing water-soluble nutrients including vitamin C, B1 and folate; The nutrients are “leaching into the water, and you’re tossing out the water.” 意为：煮蔬菜可能会导致水溶性营养素流失，包括维生素C、B1和叶酸；营养成分会“渗入水中，而你又把水倒掉了”。因此B选项正确。Q4. D. 推理题。题目出处：Besides making vegetables taste better, a little cooking oil helps the body to absorb fat-soluble vitamins, said Pankonin. 意为：除了让蔬菜更美味外，一点点食用油还能帮助身体吸收脂溶性维生素。因此D选项正确。Q5. B. 主旨题。题目出处为整篇文章的核心内容，尤其是“Cooking methods do affect nutrition” 和“Cooking changes the structure of vegetables which increases what dietitians call bioavailability.”。 意为：烹饪方法确实会影响蔬菜的营养；烹饪会改变蔬菜的结构，从而增加生物利用度。因此B选项正确。（本文图片来源于摄图网，版权归摄图网所有)

Minimize contact with animals in affected areas.D. Get vaccinated immediately.Part II. TRANSCRIPTAvian InfluenzaVismita Gupta-Smith: We’ve been hearing about avian influenza or bird flu. (Q1) Why is WHO concerned about it? Who is at risk and how can you protect yourself? Here to talk about it is Doctor Wenqing Zhang. Welcome, Wenqing, talk to us about avian influenza and how it’s affecting humans.avian adj. 鸟（类）的；关于鸟（类）的Dr. Wenqing Zhang: Avian influenza or bird flu is a disease in birds caused by a virus. Sometimes the virus makes them sick, but sometimes the birds don’t get sick from the disease but act as carriers of the virus. We’ve also seen this virus in mammals such as foxes, minks, seals and sea lions, and most recently in cows in the US. In rare cases, people have also been infected when in contact with infected birds or mammals or contaminated environments.mink n. 水貂Vismita Gupta-Smith: So, Wenqing, if human infections are so rare, why is WHO concerned about it?Dr. Wenqing Zhang: So far, close to 900 human infections have been reported. (Q2) Although the number may appear not as big as many other outbreaks, we need to bear into mind is that each infection in human is an attempt of the virus to try to establish itself in human population. Although the chances are slim so far, as long as it succeeds once, just once, it is a start of an influenza pandemic, which can be as mild as the 2009 pandemic, but equally, it could also be devastating, like the 1918 one, also called the Spanish flu. That’s why, Vismita, we are concerned about the avian influenza and are watching it very closely.pandemic n.（全国或全球性）流行病；大流行病Vismita Gupta-Smith: Talk to us about who is at risk of bird flu.Dr. Wenqing Zhang: Anyone exposed to infected live or dead poultry or infected animals or contaminated environments such as live bird markets is at risk. (Q3) Slaughtering, de-feathering, handling carcasses and preparing poultry for consumption, especially in household settings, are also risk factors. So, if you are a poultry farmer or have chickens in your backyard, you need to be aware that you are at a potential risk of catching bird flu. (Q4) With avian influenza detected in cows in the US recently, if you are a dairy worker, you’ll also need to be aware that you are at a potential risk of catching bird flu.carcass n. 动物尸体；（尤指供食用的）畜体Vismita Gupta-Smith: Wenqing, we know that this virus is evolving constantly. Talk to us about how WHO is preparing countries for a possible pandemic.Dr. Wenqing Zhang: The risk of an influenza pandemic is persistent and is being watched closely by a long-standing global system called the Global Influenza Surveillance and Response System, also called GISRS. This system will rapidly detect an influenza pandemic virus once it enters into human population, and from there it will trigger a series of response, including the development of laboratory diagnostics and vaccines. In addition, WHO will rapidly release a series of practical guidance to countries tailored to the specific pandemic response needs.diagnostics n. 诊断学Vismita Gupta-Smith: So that’s why it’s important to keep an eye on the virus to see how it’s changing. Tell us in case of an outbreak, which foods are safe to eat?Dr. Wenqing Zhang: (Q5) Avoid consuming raw milk, eggs, and meat. Make sure you consume pasteurized or properly boiled milk and thoroughly cooked eggs and meat. If you’re handling raw products, make sure you wash your hands before and after, and follow other good food safety practices. This is, in fact, our standing advice, with or without avian influenza, because these practices protect you from many diseases.pasteurized adj.（牛奶等）巴氏消毒的Vismita Gupta-Smith: So, tell us what else the public needs to do in case of an outbreak to protect themselves.Dr. Wenqing Zhang: Be vigilant. (Q6) Minimize contact with animals in areas affected with avian influenza. Avoid contact with surfaces contaminated with animal feces. Strictly avoid contact with dead or sick animals, including wild birds. Report dead animals or request their removal by contacting local authorities. And wash your hands frequently and thoroughly, especially after contact with animals and their environments.vigilant adj. 警觉的；警惕的；警戒的；谨慎Vismita Gupta-Smith: Thank you, Wenqing. There you have it, Science in 5 today. Until next time then, stay safe, stay healthy and stick with science.Part III. KEYQ1. C. 主旨题。文章主要围绕禽流感展开，开门见山提出了“Why is WHO concerned about it? Who is at risk and how can you protect yourself?”，可知文章主要讨论了与禽流感相关的风险、担忧和预防措施。因此答案为C。Q2. B. 细节题。根据“...each infection in human is an attempt of the virus to try to establish itself in human population.” 可知每一次人类感染都是病毒试图在人类群体中立足的一次尝试，因此答案为B。Q3. D. 细节题。根据“Slaughtering, de-feathering, handling carcasses and preparing poultry for consumption, especially in household settings, are also risk factors.” 可知屠宰、拔毛、处理家禽尸体以及准备食用家禽等行为，尤其是在家庭环境中，会使人们面临感染禽流感的风险。因此答案为D。Q4. A. 推理题。根据“With avian influenza detected in cows in the US recently, if you are a dairy worker, you’ll also need to be aware that you are at a potential risk of catching bird flu.”可知因为最近在美国的奶牛中发现了禽流感，所以奶牛场工人也需要意识到自己有感染禽流感的风险。因此答案为A。Q5. B. 细节题。根据“Avoid consuming raw milk, eggs, and meat.”可知要避免食用生牛奶、生鸡蛋和生肉。因此答案为B。Q6. C. 细节题。根据“Minimize contact with animals in areas affected with avian influenza.” 可知在受禽流感爆发期间，公众要尽量减少与受影响地区动物的接触以保护自己。因此答案为C。（本文图片来源于摄图网，版权归摄图网所有)

TRANSCRIPTHypertensionVismita Gupta-Smith: When my mother was detected with hypertension at the age of 60, it was a huge surprise to us as a family. And it was our first time that we were faced with this condition called hypertension. (Q1) Today, we are going to talk about hypertension or high blood pressure. How big is the problem? What exactly happens in your body when you have hypertension, and how can you protect yourself? And here to talk to us about it is Doctor Taskeen Khan. Welcome, Taskeen. Talk to us about hypertension. Why is it called the ‘silent killer’?hypertension n. 高血压Taskeen Khan: Thank you, Vismita. Quite excited to talk to you about hypertension. (Q2) And the reason why it’s called a ‘silent killer’ is because it’s completely symptomless. So what you described with your mum walking around, perfectly okay, and then suddenly finding out that you have high blood pressure. And high blood pressure leads to deadly conditions like heart attack, stroke, kidney disease, but is completely symptomless.Vismita Gupta-Smith: So, Taskeen, how big is this problem of hypertension?Taskeen Khan: Actually, it’s very common. It affects one in three adults globally, and yet only one in five people are actually controlled for their blood pressure. (Q3) We’ve actually estimated at the WHO that we can save 76 million lives by 2050 if we can increase control rates globally. That’s about the size of South Africa, Vismita.Vismita Gupta-Smith: So, Taskeen, how did I do?Taskeen Khan: You did very well. This top number is your systolic blood pressure, which is actually when the heart muscle contracts or beats. And this bottom number is your diastolic blood pressure, which is when your heart muscle relaxes.systolic adj. 心脏收缩的diastolic adj. 心脏舒张的Vismita Gupta-Smith: So, explain to us what exactly happens in our body when we have high blood pressure.Taskeen Khan: There are vessels in your body called arteries and these arteries carry oxygenated blood to your organs. (Q4) When hypertension occurs, it thickens these arteries or makes them stiff or has little clots in them. And those clots actually travel to the heart or the brain and cause heart attacks and strokes.artery n. 动脉oxygenate v. 供氧；输氧clot n. 凝块；血块Vismita Gupta-Smith: Taskeen, give us your top tips to manage high blood pressure and also to prevent it.Taskeen Khan: Of course. So the first thing is to start off like your mom did, seeking medical care, going regularly to the doctor if you are diagnosed with hypertension and taking your medication as prescribed. Personally, Vismita, my own grandmother has hypertension, I diagnosed her and I put her on the same medication that the WHO guideline actually has – really good recommendations there. And also, if you think about your lifestyle, I like to think about it in the ‘Four S’s’. So if you’re smoking, please stop smoking. Reduce sodium or salt in your diet. (Q5) Sleep is very important for the blood pressure and of course reduce your stress.sodium n. 钠 Vismita Gupta-Smith: Wow, let’s see if I’ve got the ‘Four S’s’. First one, stop smoking. Take less salt, that’s the second S. Sleep more and pay attention to your sleep quality. I’m trying to do that personally. I’m slowly getting there. And what’s the fourth one?Taskeen Khan: (Q5) Stress less... Stress less.Vismita Gupta-Smith: That’s easier said than done. But that’s all we have today in Science in 5. Until next time then, stay safe, stay healthy and stick with science.Part III. KEYQ1. A. 主旨题。根据开头的“Today, we are going to talk about hypertension or high blood pressure. How big is the problem? What exactly happens in your body when you have hypertension, and how can you protect yourself?”可知此篇以高血压为主题，介绍了高血压的问题、对身体的影响和如何预防，也就是围绕高血压的全球流行情况和危害展开。因此答案为A。Q2. B. 细节题。根据“And the reason why it’s called a ‘silent killer’ is because it’s completely symptomless.”可知高血压被称为“无声杀手”是因为它完全没有症状。因此答案为B。Q3. D. 细节题。根据“We’ve actually estimated at the WHO that we can save 76 million lives by 2050 if we can increase control rates globally.”据估计，如果能全球提高控制率，到2050年可以拯救7600万人的生命。因此答案为D。Q4. C. 细节题。根据“When hypertension occurs, it thickens these arteries or makes them stiff or has little clots in them.”可知高血压会使动脉变厚、变硬或产生血块。因此答案为C。Q5. B. 推理题。根据“Stress less... Stress less” 可知减少压力是四个S中的第4个建议，压力是与高血压相关的生活方式因素之一，减少压力可以控制高血压，可推测长期压力会引发其他健康问题，进而影响高血压因此答案为B。（本文图片来源于摄图网，版权归摄图网所有)

第12届教学大赛商务英语组二等奖贺静授课

授课点评：贺静老师授课效果较好，教学目标清楚、教学方法得当、教学程序井井有条。此外，贺静老师口齿清晰，语音语调比较纯正、流利；教态端庄自然，有亲和力，教学过程中与学生互动良好，体现了以学生为主体，教师为主导的教学原则。授课分两部分。第一部分介绍该单元（Empire of Wealth）的总教学安排，用了3分30秒，时间把握得比较好。另外，设计的PPT形式多样，各种图表清楚展现了教学安排。授课开始的第三分钟，PPT显示的该单元总教学目标及三篇课文的教学目标一览无遗，加上贺静老师的阐释，清晰地传递了教学目标和学习目标，这能帮助学生在课堂内外围绕主题有效学习。紧接着，贺静老师借助PPT上的流程图比较详细地介绍了授课课文In Praise of Competitive Urges的教学安排，其中的Problem-centred教学方法对学生发现、分析和解决问题有很大帮助。之后进入第二部分：比赛授课阶段。第二部分具体授课含四个阶段。进入第一阶段Warm-up时，贺静老师显得有点紧张，但很快就调整好了状态。该阶段有教师对课文理解的提问，请学生从课文中找到相关的依据回答问题，这种做法本来值得称道，因为授课不能离开课文。但是，Warm-up阶段是课前准备阶段，因此，贺静老师在Warm-up阶段讲解课文不妥，建议把重点放在教材中的Warm-up Activities上，适当设计一些附加的活动，才符合教学逻辑。此外，在总时间为20分钟且第一阶段用了3分30秒的情况下，Warm-up阶段用了5分1秒显得有点过长。之后是第二阶段Questionnaire Results，贺静老师分析解释了调查表中的信息，谈了自己对问题的看法，期间激励学生思考、回答问题，这对培养学生的独立思考能力及理解课文非常有益。Questionnaire之后进入授课第三阶段：Wealth-flaunting Motivations / Summarizing。炫富动机是课文包含的核心内容之一。因此，讨论炫富动机有助于学生理解课文。教师要求学生从PPT上（视频13'）显示的课文段落寻找答案，并要求学生做pair work找到有关的词汇。另外，通过分析课文的修辞寓意，贺静老师阐释了文章作者的真实目的。这一点做得很好。另一方面，根据该单元内容，所授的是“综合商务英语”课程。因此，贺静老师应更多围绕语言难点、篇章结构、写作风格、文法修辞等方面进行解释，让学生对课文有更深层次的理解。第四阶段Assignment在视频18'15"开始。课后作业包括questionnaire设计、调研报告写作、相关阅读作业。这样较好兼顾了综合商务英语课程语言学习和商务实践的教学特点。建议更多以教材内容教学为主，重视语言、篇章教学，在帮助学生充分理解课文的前提下掌握一些商务知识和技能；需要结合课文融入更多的思政教育内容。点评专家：翁凤翔

第12届教学大赛英语专业组特等奖胡笑然说课

说课点评：胡笑然老师在说课环节清晰地表达了对所给文章的文本理解和基于语篇主题意义探究而开展教学的基本认识。在拿到文章后的短暂时间内，该选手对语篇进行了审读，并在此基础上快速构思了90分钟的教学设计，形成了基本的教学步骤。根据教学设计，胡老师计划选择与语篇主题相关的短视频为导入，激发学生的学习兴趣；然后以解读语篇为抓手，对语篇的主题、结构、语言、文体等方面进行分析。胡老师按照学生“学后能做”为目的，确定本课的教学目标并介绍了具体的教学步骤。她在教学设计中体现了自己的教学理念和对课文的独到见解，将课文分为三个部分，对每一部分的内容和结构进行了必要的讲解。通过解析语篇的主题，确定了语篇的中心思想，之后列举了语篇的核心概念、关键名词以及相关修饰词及其功能。胡老师将教学目标设定为学生“能做”，即能够理解语篇的主题意义，能够发现篇章结构的特征，能够与话题相同但来源不同的同类文章进行对比从而激发学生的批判性思维，能够从文章的体裁、结构、修辞等方面学习、理解和掌握语篇的关键词语，以及作者对关键概念的词语修饰和语言表达。教学设计安排了学生的小组讨论，要求学生形成有具体步骤的思维导图和概念关联，并在课堂上融入思政元素，并进行必要的陈述。最后一个环节为开放性的讨论，引导学生对不同的观点进行评论。胡老师基于丰富的教学经验和对学情的分析判断，对教学目的、教学重点、教学环节以及设计缘由作了清晰的陈述，显示了其对教学语篇的基本认识和语篇教学娴熟的驾驭能力。说课目的明确，条理清晰，设计突出主题，有一定的感染力，突出学生主体，采用活动途径，倡导体验参与，重视培养学生批判性思维和论说能力，所设计的教学环节有较好的可操作性。从整体上看，胡笑然老师有较高的人文素养和自己的教学风格，语言流畅，表述准确，知识面较广，该说课达到了较高的水准。不过胡笑然老师的时间把控不佳，说课缺乏完整性，强调篇章结构和概念理解，但忽略了教学评的一致性和一体化设计。建议她在今后的教学设计中更加重视学生在语言知识、语言技能、文化内涵、思维心智、情感态度等方面的综合发展和有效评价，积极采用探究式、任务型、交互性的教学方法，加强课外作业的安排和指导，促进学生在语言能力、人文素养、科学思维等方面的同步发展。点评专家：梅德明
