教学素材 | 人工智能会让你变笨吗？

Will AI Make You Stupid? 人工智能会让你变笨吗？难度：CET-6 偏难刘立军供稿Artificial intelligence (AI) promises greater efficiency and convenience—but is it silently weakening our ability to think? 人工智能（AI）会带来更高的效率和便利——但它是否也在悄悄削弱我们的思考能力？Early Warning Signs from Research 研究中的早期预警信号A recent MIT study raises serious concerns. Students using ChatGPT during essay-writing sessions displayed significantly reduced brain activity in regions tied to creativity and attention, as measured by EEG scans. They also struggled to recall specific parts of the content they had just written. This suggests that while AI may speed up tasks, it may also impair memory and critical engagement. 麻省理工学院最近的一项研究引发了严重担忧。研究发现，在撰写文章的过程中使用 ChatGPT 的学生，通过脑电图扫描测量的其与创造力和注意力相关的脑区活动显著减少。他们还难以回忆起自己刚刚写过的内容的具体部分。这表明，尽管人工智能可能加快任务的完成速度，但也可能损害记忆力和深度思考能力。This isn’t an isolated finding. Microsoft Research surveyed 319 professionals regularly using generative AI for over 900 tasks. Only around 60% of those tasks required deep thinking—most were routine and described as “mindless.” The majority of respondents admitted they exerted significantly less mental effort when using AI tools like ChatGPT, Gemini, or Copilot. 这并非孤立现象。微软研究院对319名经常使用生成式人工智能完成900多项任务的专业人士进行了调查。结果显示，只有大约60%的任务需要深入思考——大多数任务都是例行公事，被描述为“不动脑筋”的工作。大多数受访者承认，使用 ChatGPT、Gemini 或 Copilot 等 AI 工具时，他们的脑力投入明显减少。Similarly, a study by Michael Gerlich at SBS Swiss Business School found that heavy AI users scored lower on critical-thinking assessments. Hundreds of educators reached out to him afterward, confirming they’ve seen the same trend in classrooms: students increasingly dependent on AI struggle with independent reasoning. 同样，SBS 瑞士商学院Michael Gerlich博士的研究也发现，频繁使用人工智能的人在批判性思维评估中的得分较低。研究发表后，数百名教育工作者联系了他，证实他们在课堂上也观察到了类似趋势：越来越依赖 AI 的学生在独立思考方面遇到了困难。Is AI the Cause—or Just a Symptom? 是 AI 导致的，还是只是表象？Researchers caution that these studies don’t yet prove a direct causal link. The MIT study had only 54 participants, and Gerlich’s findings may reflect a different issue: perhaps those who already lack strong critical thinking skills are more likely to rely on AI. Still, the consistent pattern across different studies makes this an issue worth urgent attention. 研究人员警告说，这些研究尚未证明人工智能使用与思维能力下降之间存在直接的因果关系。麻省理工的研究仅涉及54名参与者，而 Gerlich博士的发现可能反映了另一个问题：也许那些原本缺乏批判性思维能力的人更倾向于依赖 AI。尽管如此，不同研究中一致的结果表明，这个问题值得高度关注。The Bigger Risk: Outsourcing Thought 更大的风险：外包思考Throughout history, technological tools have helped reduce mental workload—writing, calculators, GPS. But as psychologist Evan Risko notes, generative AI introduces a new level of cognitive offloading. While it’s harmless to delegate arithmetic, offloading complex thinking—like writing, decision-making, or problem-solving—could weaken our cognitive endurance over time. 纵观历史，技术工具一直在帮助人们减轻脑力负担——从文字书写、计算器到 GPS。但正如心理学家 Evan Risko 所指出的，生成式 AI 引入了一种新的“认知外包”层次。虽然将算术任务交给机器无伤大雅，但将写作、决策或解决问题等涉及复杂思考的任务外包，可能会逐渐削弱我们的认知耐力。This could lead to a self-reinforcing loop of “cognitive miserliness,” where users consistently choose the path of least effort. As AI becomes the default, our brains grow accustomed to underperforming. One participant in Gerlich’s study admitted: “I rely so much on AI that I don’t think I’d know how to solve certain problems without it.” 这可能导致一种“认知懒惰”的循环，即用户总是选择最省力的方式，且这一循环会自我强化。当 AI 成为默认选项，我们的大脑也会逐渐习惯低效运作。Gerlich博士的研究中有一位参与者坦言：“我对 AI 如此依赖，甚至我觉得没有它我都不知道怎么解决一些问题。”The Economic and Creative Cost 经济与创造力的代价Businesses are betting heavily on AI for productivity gains. But there’s a catch. Barbara Larson of Northeastern University warns that a long-term decline in critical thinking could reduce competitiveness—and make workers more replaceable. 企业正大力押注 AI 来提升生产力。但这也存在隐患。东北大学的 Barbara Larson教授警告说，长期来看，批判性思维能力的下降可能会削弱企业的竞争力，让员工更容易被取代。Creativity is also at risk. In one study, participants were asked to come up with novel uses for objects like a car tyre or a pair of trousers. Those exposed to AI suggestions gave less original answers. For example, ChatGPT proposed using trousers as part of a scarecrow—essentially, trousers as trousers. A human, unaided, turned them into a quirky bird feeder. Clearly, relying on AI can narrow the scope of imagination. 创造力也面临威胁。在一项研究中，参与者被要求想象一个汽车轮胎或一条裤子有什么新的用途。接受过 AI 建议的人给出的答案缺乏原创性。例如，ChatGPT 提议将裤子用作稻草人的一部分——本质上还是作为裤子的用途。而一个没有借助 AI 的人则将其改造成了一种有趣的鸟食器。显然，过度依赖 AI 会限制想象力的广度。Smarter Ways to Use AI 更聪明地使用 AI 的方法The solution isn’t to abandon AI—but to use it more wisely. Dr. Larson advises treating AI as a helpful but naive assistant, not an expert. Dr. Gerlich recommends prompting AI step by step, rather than asking for a final answer. Instead of “Where should I go for a sunny holiday?” start with “Which destinations have the least rainfall?” This preserves the user’s role as the thinker. 解决方案不是放弃 AI，而是更聪明地使用它。Larson 博士建议将 AI 视为一个有用但不够成熟的助手，而不是专家。Gerlich博士则建议分步骤向 AI 提问，而不是直接要一个最终答案。例如，不要问“我该去哪里度假？”而是先问“哪些地方降雨最少？”，这样可以保留用户作为思考者的角色。Microsoft researchers are also exploring AI designs that encourage critical thinking. Some experimental chatbots interrupt users with challenging prompts or probing questions—transforming them from passive answer machines into interactive thought partners. A concept that Socrates, the father of inquiry-based learning, would likely applaud. 微软的研究人员也在探索鼓励批判性思维的 AI 设计。一些实验性聊天机器人会通过带有挑战性的提示词或探究性的提问来打断用户，将自身从被动的回答机器转变为互动型的思考伙伴。这种理念或许会受到苏格拉底——探究式学习之父——的赞赏。The Limits of Forcing Engagement 强制参与的局限性Yet even thoughtful interventions can backfire. A study found that AI “provocations” reduced performance in weaker programmers. And more forceful methods—like requiring users to generate their own response before accessing AI—are unlikely to be welcomed. As Microsoft’s Zana Buçinca explains, “People don’t like to be pushed to engage.” Indeed, a global survey by Oliver Wyman showed that 47% of respondents would use generative AI tools even if banned by their employer. 然而，即使是经过深思熟虑的干预也可能适得其反。一项研究发现，AI 的“挑战性提问”反而会降低编程能力较弱者的表现。而更强制性的方法——比如要求用户在访问 AI 前必须先自行生成答案——也不太可能受欢迎。正如来自微软的Zana Buçinca 所说：“人们不喜欢被强迫去思考。”事实上，奥纬咨询公司（Oliver Wyman）的一项全球调查显示，47%的受访者即使雇主禁止，也会继续使用生成式 AI 工具。A Tool, Not a Crutch AI：工具，而非拐杖AI is still young, and for now, the human brain remains the most versatile tool we have. But we must be careful not to trade long-term mental sharpness for short-term convenience. If strong evidence continues to show that AI dulls critical and creative thinking, we’ll face a choice: adjust how we use it—or risk becoming intellectually dependent on it. 人工智能仍处于早期阶段，目前，人类大脑仍然是我们最灵活的工具。但我们必须小心，不要为了短期便利而牺牲长期的思维敏锐性。如果越来越多的证据显示 AI 确实削弱了批判性与创造性思维，我们将面临一个选择：调整使用方式——或冒着在智力上对AI愈加依赖的风险。The question is not just can AI make us less intelligent—but will we notice before it does? 问题不仅仅是 AI 是否会让人类变笨——而在于我们是否在它将我们变笨之前就能察觉到？【词汇】 1. offload v. 卸载，转移 2. miserliness n. 吝啬 3. quirky adj. 匆匆做成的，速成的 4. backfire v. 事与愿违，产生反效果 5. crutch n. 拐杖，依赖物 （本文图片均来源于网络，仅供学习交流使用，侵删）

教学素材 | 《卫报》评论：莫让AI掩盖青年才俊的光芒

《卫报》评论：莫让AI掩盖青年才俊的光芒The Guardian view on the graduate jobs crunch: AI must not be allowed to eclipse young talent 词汇：考研 | 句法：六级 | 文本：考研刘立军供稿As annual degree ceremonies take place on campuses across the country, new graduates will doubtless be turning their thoughts to enjoying some stress-free time off. Given the current state of the labor market, some may be forced to make that break a long one. 随着全国各地高校陆续举行一年一度的毕业典礼，新一届毕业生无疑会想着享受一段轻松无忧的假期。然而，鉴于当前就业市场的严峻形势，有些人可能不得不把这段空档期拉得很长。For university leavers, these are worrying times. A mounting pile of data suggests that accessing the kind of entry-level jobs that traditionally put degree holders on a path to professional success is becoming ever harder. One report published last month by the job-search site Indeed found that the market for young people fresh out of university is tougher than at any time since 2018. Compared with last year, the number of jobs advertised for recent graduates is down 33%. 对于即将走出大学校门的年轻人来说，这是个令人焦虑的时期。越来越多的数据表明，进入那些传统上为大学毕业生铺就职业成功之路的入门级岗位，正变得越来越困难。求职网站Indeed 上个月发布的一份报告显示，应届毕业生所面临的就业市场比自2018年以来任何时期都要严峻。与去年相比，面向应届毕业生的职位数量下降了33%。Some of the squeeze can be put down to a general slowdown in hiring, as employers opt for caution in an unpredictable, growth-starved economic climate. Another analysis, published this week, found that the number of entry-level jobs on offer throughout the labour market has fallen. But the steepest drop-off appears to be in professional occupations, where the impact of artificial intelligence (AI) may be beginning to affect the bottom rungs of the white-collar career ladder. 部分原因是整体招聘活动放缓，雇主们在经济前景不明朗、增长乏力的环境下选择谨慎行事。本周发布的另一项分析也发现，整个劳动力市场上提供的入门级岗位数量有所减少。但降幅最显著的领域似乎集中在专业岗位。在这类岗位中，人工智能（AI）的影响可能已开始波及白领职业阶梯的最底层。According to some analysts, a growing number of companies are using AI to perform many of the collative, summarizing or research-heavy kind of tasks that young graduates might previously have done. IBM’s human resources department now deploys AI to perform 94% of routine tasks, including performance reviews and development plans. Other employers may be hiring fewer graduates than in the past on the assumption that the use of AI will transform their productivity. 一些分析人士指出，越来越多的公司正在使用人工智能来完成许多原本由年轻毕业生承担的工作任务，比如资料整理、总结归纳或研究密集型工作。例如，IBM 的人力资源部门现在利用人工智能完成了94%的常规性任务，包括绩效评估和发展计划制定。其他雇主也可能因预期人工智能能提高效率而减少了对毕业生的招聘。For a graduate cohort whose education was blighted by the pandemic, and which is burdened by an average student debt of about £45,000, such developments risk stunting careers before they have begun. Recruitment systems are steadily being transformed through the introduction of AI-driven sifting processes, in which applications are rejected without a human judgment being made. A sustained contraction of the graduate job market, as pathways into professional careers are shortsightedly shut down in the name of cost savings, would further undermine trust between the generations at a time when it is already in short supply. 对于那些学业受到疫情影响、平均背负约4.5万英镑学生债务的毕业生而言，这样的趋势可能会在职业生涯尚未起步时就造成阻碍。与此同时，招聘系统也在悄然发生变化，越来越多的企业采用基于人工智能的筛选机制，导致许多职位申请在缺乏人工判断的情况下就被直接回绝。如果企业在追求节约成本的过程中，盲目关闭通往专业岗位的通道，加之毕业生就业市场持续萎缩，只会进一步削弱本已脆弱的代际信任。The technology minister, Peter Kyle, has urged businesses and employees to “act now” in gaining AI skills or risk being left behind, and the government hopes to collaborate with tech companies to deliver training to 7.5 million workers. But a focus on those hoping to enter the digitized workplace is also clearly needed. The evidence that entry-level jobs in areas such as law, finance and consulting are becoming scarcer should set alarm bells ringing in both government and boardrooms. 科技大臣彼得·凯尔敦促企业和员工“立即行动”，掌握人工智能相关技能，否则将被时代抛弃。政府也希望与科技公司合作，为750万名工人提供培训。然而，我们显然也需要特别关注那些即将进入数字化职场的年轻人。法律、金融和咨询等领域的入门岗位日益稀缺，这一趋势应该引起政府和企业高层的高度警觉。Politically and economically, the country cannot afford to waste the acquired skills, creativity and dynamism of those who have actually come of age in the digitized world. That may mean companies eventually reimagining the spectrum of early career opportunities that can be offered to recent graduates. But business and government should make it a priority to ensure that they are given the openings and encouragement they need in a rapidly transforming environment. Innovations such as ChatGPT have become embedded in everyday life at vertiginous speed. But their benefits must not come at the expense of the young talent that will be crucial to shaping our future. 从政治和经济层面来看，国家承担不起浪费这部分人才潜能的代价——他们是真正在数字化时代成长起来的群体，拥有已习得的专业技能、创新能力与活力。这意味着企业最终需要重新思考并拓展面向应届毕业生的早期职业机会。政府和企业必须优先确保这些年轻人能够在快速变革的环境中获得应有的机会和激励。像 ChatGPT 这样的创新技术已经以惊人的速度融入日常生活。但它们带来的便利，绝不应以牺牲未来塑造者——年轻人才的利益为代价。【词汇】1. rung n. 梯级，等级 2. cohort n. 群体，同龄人 3. pandemic n. 大流行病 4. stunt v. 阻碍 5. contraction n. 收缩，缩减 6. digitize v. 数字化 7. dynamism n. 活力，动力 8. vertiginous adj. 令人眩晕的，陡峭的 （本文图片均来源于网络，仅供学习交流使用，侵删）

Do you need an energizing blast of water in the morning to wake you up for the day? Or do you prefer a relaxing, warm shower in the evening to help you wind down as part of your nighttime routine? Maybe you just shower whenever you feel like it. For something so many of us do, this topic is bound to divide opinion and stir up passion from both sides. But is one really better than the other?After a long day in the outside world, picking up pollutants and allergens on your skin and in your hair such as dust and pollen, a reasonable instinct would be to wash it all off before getting into bed. That’s what the evening shower enthusiasts would say. But, says microbiologist Primrose Freestone, no matter the air temperature, you will continue to sweat during the night. Bacteria on your skin then eat the nutrients in your sweat which is what causes BO. Showering at night also doesn’t stop you shedding dead skin cells. All this means you may not wake up feeling as fresh as you had hoped. [Q1] Showering in the morning, on the other hand, can help to remove dead skin cells, sweat or any bacteria you’ve picked up from your bed sheets. “As a microbiologist, I am a day shower advocate,” she says.allergens n. 过敏原pollen n. 花粉nutrient n. 营养物质microbiologist n. 微生物学家BO (body odor) 汗臭，体臭But it’s not all about cleanliness. Nancy Rothstein, who calls herself The Sleep Ambassador, is concerned with sleep quality. (Q2) In her view, showering in the evening is an essential part of the ‘preparing for bed’ routine. “Call it an opportunity to shower yourself with mindfulness,” she says. And research backs this up. (Q3) A systematic review of research published in Sleep Medicine Reviews in 2019 found nightly warm showering or bathing one to two hours before bedtime can improve sleep.(Q4) What it all boils down to is when you would like to feel freshest. If you’re someone who can’t fully relax in bed until you’ve showered, you’re likely an evening shower person. Whereas, if you can’t stand the idea of putting on fresh, clean clothes in the morning when you haven’t showered, then a morning rinse is probably more your style. Whenever you choose to shower, Primrose Freestone says it’s important to clean your bed sheets regularly to remove all the sweat, bacteria and dead skin cells that build up and can negatively affect the effectiveness of your showers.rinse n. 冲洗Part III.

TRANSCRIPT ConcussionTranscriptVGS: It’s a wet and rainy day in Geneva but Science in 5 crew is very determined. It’s an all-women crew today. So come rain and shine, we’re going to shoot this. We’re going to talk about concussion today. If you have children who play sports or you play sports, you need to know about concussion. What is it? How will you know if you have concussion? And what can you do to prevent it? And here to talk about it today is Dr Tarun Dua. Welcome Tarun.concussion n. 脑震荡TD: Hi!VGS: Tarun, talk to us about what is concussion.TD: (Q1) So, concussion is a type of traumatic brain injury. (Q2) So, if you have a bump, blow to the head or even to the body. What happens is, the forces can lead to your brain moving and bouncing around, leading to damage to brain cells. And any activity can cause concussion. So, for example, you fall in this wet, rainy field or you are playing sports, like football, It also happens during road traffic accidents. For example, in Australia, one in five people who presented to the hospital with concussion, they had it while playing sports.traumatic adj. 外伤的VGS: So, we’ve just established that these are pretty perfect conditions for a concussion that we are filming in. But, actually, I fell down a little while ago and I was wondering if I had concussion. I didn’t know what the symptoms would be. Can you talk about that?TD: So, concussion is not something that you will see outside and the other thing is, it’s not that symptoms are going to happen immediately. They can actually also happen up to 72 hours after the injury. (Q3) So common symptoms are you will have headache or pressure sensation, nausea, feeling dizzy, loss of balance, memory, unable to focus, sleep problems. So these are very common problems. Then sometimes you have severe symptoms, like convulsions. You can have loss of consciousness or weakness or numbness and that means you need to, in any case, you need to go immediately to get any help. So, did you have any of those symptoms, Vismita?sensation n. 感觉nausea n. 恶心，反胃convulsion n. 痉挛numbness n. 麻木VGS: Well, no, I think I felt a little bit of brain fog or a little bit of confusion which is what worried me. But also, it’s about sometimes, when you take a fall you’ve also not really thought about the fact that with, as you age, you need to work on your balance better and stuff like that. So talk to us also about the prevention of concussion.TD: There are many things all of us can do. (Q4) So, for example, riding a bicycle, wear a helmet. (Q5) Home environment, make sure that your carpets and cables are not interrupting. And especially for older people, they’re very important, that we make our homes friendly and fall free as much as possible. Playing contact sports, ensure that you are wearing protective equipment, you are aware of your surroundings. So I’m looking around, the ball is not going to come and hit me. And do not take unnecessary risk. This is especially true for young people. So, these are many things that we can do to prevent concussion.helmet n. 头盔VGS: Talk about the treatment of concussion. Sometimes you hear that, ‘Oh, it’s okay, it will just go away.’ Is that true, for instance?TD: One of the things about concussion is not everyone is aware about it and so very often it goes undetected. People don’t know and they don’t go to seek medical help. (Q6) So it’s very important, that if you have had a fall, just ensure that you seek medical help. Go and show it to the doctor. That evaluation is extremely important and the second is that (Q7) you need to take rest, both physical and mental because it will help you recover quickly. (Q8) And the third thing that you need to do is avoid repeat injuries. Avoid repeat concussion because we know repeat concussions can lead to long-term damage, including dementia. dementia n. 痴呆，精神错乱VGS: That sounds very scary, especially because senior citizens will also experience, sometimes, increased falls and that can actually contribute to dementia, you said, right? Talk to us about some other long-term impacts of concussion.TD: You can have long-term memory problems, you can have long-term sleep problems. It can impact your education, learning. (Q9) I’m thinking about the young people and also, especially if you’re thinking about sports, because, you know, you’re getting it at a young age we are worried about the risk of neurocognitive issues such a dementia.VGS: We’re going to wrap up, but give our audience a few tips for how to avoid concussion.TD: Important is that wear protective equipment, you are riding a bicycle, you are playing a sport. When you are in your home, just ensure that you are keeping your carpets, your cables, so that you are not falling down on any of those surfaces and be aware of your surroundings.VGS: Thank you, Tarun. That was Science in 5, today, from a wet and rainy Geneva. Until next time then, stay safe, stay healthy and stick with science. Part III. KEYQ1.

Do you need an energizing blast of water in the morning to wake you up for the day? Or do you prefer a relaxing, warm shower in the evening to help you wind down as part of your nighttime routine? Maybe you just shower whenever you feel like it. For something so many of us do, this topic is bound to divide opinion and stir up passion from both sides. But is one really better than the other?After a long day in the outside world, picking up pollutants and allergens on your skin and in your hair such as dust and pollen, a reasonable instinct would be to wash it all off before getting into bed. That’s what the evening shower enthusiasts would say. But, says microbiologist Primrose Freestone, no matter the air temperature, you will continue to sweat during the night. Bacteria on your skin then eat the nutrients in your sweat which is what causes BO. Showering at night also doesn’t stop you shedding dead skin cells. All this means you may not wake up feeling as fresh as you had hoped. [Q1] Showering in the morning, on the other hand, can help to remove dead skin cells, sweat or any bacteria you’ve picked up from your bed sheets. “As a microbiologist, I am a day shower advocate,” she says.allergens n. 过敏原pollen n. 花粉nutrient n. 营养物质microbiologist n. 微生物学家BO (body odor) 汗臭，体臭But it’s not all about cleanliness. Nancy Rothstein, who calls herself The Sleep Ambassador, is concerned with sleep quality. (Q2) In her view, showering in the evening is an essential part of the ‘preparing for bed’ routine. “Call it an opportunity to shower yourself with mindfulness,” she says. And research backs this up. (Q3) A systematic review of research published in Sleep Medicine Reviews in 2019 found nightly warm showering or bathing one to two hours before bedtime can improve sleep.(Q4) What it all boils down to is when you would like to feel freshest. If you’re someone who can’t fully relax in bed until you’ve showered, you’re likely an evening shower person. Whereas, if you can’t stand the idea of putting on fresh, clean clothes in the morning when you haven’t showered, then a morning rinse is probably more your style. Whenever you choose to shower, Primrose Freestone says it’s important to clean your bed sheets regularly to remove all the sweat, bacteria and dead skin cells that build up and can negatively affect the effectiveness of your showers.rinse n. 冲洗Part III.

TRANSCRIPTSnakebites: Life saving factsTranscriptVGS: Growing up in India, (Q4-1) we even saw it in movies that if you’re bitten by a snake, you should suck the venom out and spit it out. Does this work?venom n. 毒液DW: If you’re sucking the venom out, you can end up with two people being bitten by the snake and not just one.VGS: We are talking about snakebites today. Why should you be concerned? Because one person dies every four minutes across the world because of snakebites. Here to talk about it today is Dr David Williams. Welcome David, talk to us about the scenarios where people are being bitten by snakes.DW: Okay, well, look, (Q1) the average person who gets bitten by a snake is an ordinary individual. They could be a farmer, a cow herder, a school child, mum, dad, somebody coming from a rural community usually, in Asia, Africa, Latin America or somewhere like New Guinea. And these are people who are just going about their day, and they make a simple mistake that leads to them being bitten.VGS: David, how big is this problem and why is WHO concerned about it? DW: Well, (Q2) snakebites are a really important public health issue. (Q3) There’s about 2.7 million people who are bitten by snakes every year. And between 81,000 and 138,000 of them lose their lives.VGS: Can snakebites be prevented? What can we do to make sure we’re safe from snakes?DW: Well, you know, the old adage is that prevention is better than the cure. Avoiding situations where snakebites can happen doesn’t cost you anything, and really just involves doing things that are common sense that can lower your risk of contact with a snake in the first place. And it’s really important that if you go outside at night, have some sort of light, whether it’s a torch, even inside the home, don’t stumble around in the dark and tread on a snake that you don’t see. Turn a light on. If you sleep on a bed that’s off the ground covered with a well tucked in mosquito net. It doesn’t just prevent malaria and other mosquito borne diseases. (Q5) It’s been proven in countries like Nepal to reduce the risk of snakebite while sleeping enormously. And probably the most important thing. Children are really vulnerable to snakebites. So, you have to talk to them, educate them, (Q6) make sure they know to leave snakes alone, not try to catch and kill them, and teach them that if they see a snake, they should inform an adult straightaway.adage n. 格言，谚语malaria n. 疟疾，瘴气Nepal n. 尼泊尔（南亚国家名）straightaway adv. 立刻，直接地VGS: So, David growing up in India we heard and even saw it in movies that when you are bitten by a snake you should tie that part and cut that wound even suck the venom out and spit it out. It sounds dangerous. What does science say about this? What should people do when bitten by a snake?DW: Okay, so the thing about movies is that they’re fiction. And the hero and the heroine are never allowed to die. Unfortunately, (Q4-2) those techniques in real life, it’s not just that they don’t work. It’s also that they can be very dangerous. A tourniquet applied too tight can cost you your leg, can end up having to be amputated. (Q7) If you’re sucking the venom out, and you have poor dental hygiene, you can end up with two people being bitten by the snake and not just one. The most important thing is, like any accident. Don’t panic. Don’t waste time getting to the nearest health center or hospital as quickly as you can. The best chance you’ve got of survival, essentially, is if you get proper medical treatment within the first 4 to 6 hours. So harmful first aids and traditional remedies should be avoided. And the basic principle of first aid is to first do no harm so don’t tie a rope or wire around the limb, don’t cut the wound. And certainly don’t do things like applying electric shocks. Another thing that’s important is that when people get bitten by a snake, sometimes they will become sick. And so if you give them food or drink, they can actually choke on that. (Q8) So you really shouldn’t give them anything by mouth. If they have rings, bangles, watches, other tight things on their bodies around the area where they were bitten, you should remove those as well, because sometimes snakebite causes a lot of local swelling, and those sorts of objects can really cut off the circulation. And then the most important thing is never lay a person on their back, especially in a vehicle on their way to health care. (Q9) Put them on their left side. And what we call the recovery position, with their head sort of tilted to the side and downwards. And that can actually prevent them from losing their ability to breathe and also prevents them from literally choking to death on their own vomit.tourniquet n. 止血带amputate v. 截肢bangle n. 手镯，腕带vomit n. 呕吐物VGS: David, talk to us about the treatment for snakebites. Are antivenoms available readily around the world?DW: Okay, well unfortunately, many countries face shortages when it comes to having enough supplies of safe, good quality and effective antivenom drugs. (Q10) So to this end, WHO is helping countries by identifying the best products that they can use. Providing technical guidance to manufacturers to help them improve and develop and design other products. And we’re also looking at new ways to supply antivenoms to even the remotest parts of the world so that more people can easily access treatment.effective adj. 有效的，起作用的VGS: Thank you David. That was Science in 5 today. Until next time then stay safe, stay healthy, and stick with science.Part III. KEYQ1.

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届教学大赛商务英语组特等奖潘紫萌授课

授课点评：潘紫萌老师在本次大赛中与来自全国各地的商务英语优秀教师展开激烈角逐，在教学理念、教学方法、课堂设计、英语素质、商务知识、教姿教态、师生互动等方面的表现都较突出，最后以总分第一荣获特等奖。潘老师以准确的英语发音先声夺人，丰富的表达方式、适中的语调语速和端庄的教姿教态也令人印象深刻。在课程设计环节，为实现其教学目标，她选择business ethics作为主题，介绍了教学目标、学生特征、以学生为中心和以产出为导向的教学理念，以及线上线下结合、传统和高科技媒体结合等丰富多彩的教学方式。这份介绍全面立体但简明扼要，为后面的演示（demo）课提供了一个很好的支撑。由于大赛的授课时间有限，潘老师突出重点，在演示课上只展示教学方案的第三步，即participatory learning 1 和 post assessment 1。她采用BOPPPS（bridge in, objectives, pre-assessment, participatory learning, post assessment, summary）模型，通过德国大众汽车减排作假、中国支付宝公益植树项目等案例，教学目标涵盖商务英语知识、技能、以及相关的伦理和价值观等。在短短的十几分钟里要达到这么多项教学目标绝非易事。潘老师通过一系列的短视频、多种教学方法（如听力填空、案例讨论、汉译英、样本对话补正等）以及活泼的师生互动，较好地实现了教学目标，显示出选手突出的课堂组织能力。商务英语教学起源于英美等国，因此基本使用本国素材、讲本国故事。传入中国后，主要使用外国素材、讲外国故事。令人欣喜的是，潘老师注意突出中国特色，多次引用中国案例，讲授中国故事，传播中国价值观。加上她出色的英语基本功和良好的师生互动，使得教学过程十分流畅，也没有不同文化同场展示的违和感。总而言之，潘紫萌老师在授课环节的各方面表现都很优秀。不足之处当然也有。首先， 8’13’’开始的讨论过于仓促，只有18秒， 8’31’’就结束了。由于讨论不充分，在随后的问答环节中，更多的回答似乎来自老师而不是学生。第二个是要增加教学过程的自然自发 (spontaneity)。不知是因为课前多次排练还是老师特意要求，学生的产出只有一次对话（17’40’’）相对自然，其他的多次回答虽准确无误，但都像中国小学生朗读课文或回答问题，语音、语调、语速都过于整齐合一，这不利于培养学生的英语实际表达能力。点评专家：陈准民
