To highlight the importance of avoiding naps entirely. B. To discuss the link between naps and cardiac health. C. To analyze the role of circadian rhythms in sleep. D. To explain the benefits and drawbacks of napping. Part II. TRANSCRIPTNaps might not be as good for you as you think Surely, they're called power naps for a reason? Aren't naps the key to feeling alert, improving your memory and just generally having a great life? Well, they can be, but things aren't quite that simple.(Q1) It is true that a short nap can help people be more alert, improve their memory and concentration, and reduce risks around tasks with heavy machinery. Our circadian rhythms are responsible for the notorious lull that many of us feel in the early afternoon. This is the best time for a nap. Some companies have installed sleep pods for their employees, hoping to benefit from increased productivity and cognitive performance. But it is also true that naps can cause problems.circadian adj. 生理节奏的，昼夜节律的 notorious adj. 声名狼藉的，众所周知的（常指不好的事情） lull n. 间歇，平静期 pod n. 小舱，隔间 cognitive adj. 认知的 Let's start by thinking about the length. (Q2) A true power nap should be less than half an hour. Any longer, and it becomes hard to rouse yourself from. Any benefits in terms of alertness are likely to disappear with the grogginess that results from a longer period of slumber.grogginess n. 昏昏沉沉，虚弱无力slumber n. 睡眠，微睡 This isn't the only issue. Naps have been linked to conditions such as diabetes, high blood pressure and cardiac problems. However, it's not clear whether these are direct results, or stem from the impact of napping on our sleep habits. (Q3) If you take a nap after about two or three in the afternoon, it's likely to have a negative effect on your ability to get to sleep at night. Breaking your sleep cycle can lead to bad sleeping habits, which themselves become ingrained.cardiac adj. 心脏的 ingrain v. 使根深蒂固 Of course, in the same way that naps can lead to bad sleep, it's also true that bad sleep can lead to wanting to take more naps. (Q4) So, if you find yourself frequently needing to sleep during the day, experts suggest that you consider why that's the case. Are there any potential health issues that could be causing insomnia? Or are work pressure stopping you from getting enough sleep?insomnia n. 失眠 Part III. KEYQ1.【答案】B【解析】细节题。题目出处：It is true that a short nap can help people be more alert, improve their memory and concentration, and reduce risks around tasks with heavy machinery. 意为：“的确，小睡片刻能帮助人们更加清醒，提升记忆力和专注力，还能降低操作重型机械等作业时的风险。” 因此正确答案为B。 Q2.【答案】A【解析】细节题。题目出处：A true power nap should be less than half an hour. 意为：“真正的有效小憩时间应控制在半小时以内。。” 文章明确指出，有效小睡的时间应该少于半小时，超过这个时间可能会导致昏昏沉沉，并抵消小睡的益处，因此正确答案为A。 Q3.【答案】C【解析】细节题。题目出处：If you take a nap after about two or three in the afternoon, it's likely to have a negative effect on your ability to get to sleep at night. Breaking your sleep cycle can lead to bad sleeping habits, which themselves become ingrained. 意为：“如果你在下午两三点之后小睡，很可能会对夜间入睡能力产生负面影响。打乱睡眠周期会导致不良的睡眠习惯，而这些习惯本身又会变得根深蒂固。”因此正确答案为C。 Q4.【答案】B【解析】推理题。题目出处：So, if you find yourself frequently needing to sleep during the day, experts suggest that you consider why that's the case. Are there any potential health issues that could be causing insomnia? Or are work pressures stopping you from getting enough sleep? 意为：“因此，如果你发现自己经常需要在白天睡觉，专家建议你思考原因。是否存在可能导致失眠的潜在健康问题？或者工作压力是否阻碍你获得足够的睡眠？从中可以推断，频繁白天小睡可能表明存在潜在健康问题或压力，因此正确答案为B。 Q5.【答案】D【解析】主旨题。文章主要讨论了小睡的好处和可能引发的问题，包括提高注意力和记忆力的益处，以及可能导致睡眠周期紊乱和健康问题。因此正确答案为D。 （本文图片来源于摄图网，版权归摄图网所有)

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）

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）

Seasonal affective disorder only affects people in cold climates.Part II. TRANSCRIPTHow to Keep from Feeling Down in the WinterFrom VOA Learning English, this is the Health & Lifestyle report.(Q1) As fall and winter come to some parts of the world, daylight hours grow shorter. This lack of light can cause seasonal depression.“It is a feeling of panic, fear, anxiety and dread all in one,” said Germaine Pataki. The 63-year-old woman living in Saskatoon, Saskatchewan, Canada, is among the millions of people estimated to have seasonal affective disorder, or SAD.dread n. 恐惧，畏惧 disorder n. 混乱，失调To deal with her condition, Pataki uses yoga, walking, and an antidepressant medication. She is also part of a Facebook group for people with SAD and helps others deal with the condition. Pataki said, “This gives me purpose.”yoga n. 瑜伽medication n. 药物，药物治疗People with SAD usually have depression that begins in the fall and eases in the spring or summer. Changing the clocks back to standard time, which happens in autumn in the United States, can also cause SAD to start.Medical experts say there is a milder form, called subsyndromal SAD. There is also summer seasonal depression but less is known about that.In 1984, a team led by Dr. Norman Rosenthal, then a researcher at the National Institutes of Health, first described SAD. He invented the term.What causes seasonal affective disorder?Scientists are still learning the causes of seasonal affective disorder. (Q2) They have found that specialized cells in our eyes turn the blue wavelength of the light into neural, or brain signals. These signals affect mood and wakefulness, or alertness.neural adj. 神经的Sunlight has a lot of blue light. So, when the cells sense this blue light, the alertness centers of our brains turn on. We feel more alert and possibly even happier.Kathryn Roecklein is a researcher at the University of Pittsburgh. She tested people with and without SAD to see how their eyes reacted to blue light. As a group, people with SAD were less sensitive to blue light than others, especially during winter months. That suggests a cause for wintertime depression.“In the winter, when the light levels drop, that, combined with a lower sensitivity, might be too low for healthy functioning, leading to depression,” Roecklein said.Miriam Cherry is 50 years old and lives in New York state. She spent the summer planning how she would deal with her winter depression. “It’s like clockwork,” Cherry said. “The sunlight is low. The day ends at 4:45, and suddenly my mood is horrible.”clockwork n. 钟表机械Light therapy can help(Q3) Many people with SAD respond to light therapy, said Dr. Paul Desan of Yale University’s Winter Depression Research Clinic. The therapy devices give off light about 20 times brighter than regular indoor light.“The first thing is to try light,” Desan said. “When we get patients on exposure to bright light for a half an hour or so every morning, the majority of patients get dramatically better. We don’t even need medications.”There is research that supports the idea that using a light that has a brightness of about 10,000 lux can be helpful. Lux is a measurement of brightness.The research suggests that a person use it for 30 minutes every morning. Desan said this can help not only people with SAD but also those with less-severe, low moods in winter.What else might work?Experts suggest other forms of treatment. Doctors often suggest antidepressant medications as a first-line treatment for SAD. They also suggest going to bed and waking up at about the same time each day. Also, exercise such as walking outside, even on cloudy days, can help.Kelly Rohan is a researcher at the University of Vermont. Rohan said another treatment is talk therapy. Also called cognitive behavioral therapy, or CBT, Rohan said it has been shown in studies to have more long-lasting effects. CBT involves working with a therapist to identify and change unhelpful thoughts.cognitive adj. 认知的“A very common thought that people have is ‘I hate winter,’” Rohan said. She suggests that people instead say, “I prefer summer to winter.”Working with a therapist can help people take small steps toward having fun again, Rohan said. Try planning undemanding but enjoyable activities to break out of a bad mood. Rohan said simply meeting a friend for coffee can help.People with SAD have half the year to create helpful methods. Some have found things that work for them — although they might not be the subject of scientific research.For example, in Folsom, California, Elizabeth Wescott says she believes a kind of water therapy helps her. The 69-year-old uses water therapy used in sports medicine. When she showers, she changes between hot and cold water. She also uses a light box and takes an antidepressant. “I’m always looking for new tools,” Wescott said.In New York, Miriam Cherry grows the earliest blooming flowers. They bloom as early as February.(Q4) “That’s going to be a sign to me that this isn’t going to last forever,” Cherry said. “It will get better, and spring is on the way.”And that’s the Health & Lifestyle report.Part III. KEYQ1. C. 【解析】细节题。根据：“As fall and winter come to some parts of the world, daylight hours grow shorter. This lack of light can cause seasonal depression.” 可知随着秋冬季节的到来，白天的时间变得越来越短，这种日光时间不足可能会引发季节性抑郁症。因此答案是C。Q2. B. 【解析】细节题。根据：“They have found that specialized cells in our eyes turn the blue wavelength of the light into neural, or brain signals. These signals affect mood and wakefulness, or alertness.” 可知眼中的特殊细胞将蓝光波长转化为神经或大脑信号，进而影响情绪和清醒度。因此答案是B。Q3. A.【解析】细节题。根据：“Many people with SAD respond to light therapy.” 文章中提及光疗对许多患有SAD的人有效，是建议的一个疗法。因此答案是A。Q4. D. 【解析】推理题。根据：“‘That’s going to be a sign to me that this isn't going to last forever,’ Cherry said. ‘It will get better, and spring is on the way.’” 可知Cherry将花作为一种信号，提醒自己这不会永远持续下去。情况会好转，冬天即将结束，春天即将来临。因此答案是D。Q5. B.【解析】主旨题。报告讨论了针对季节性情感障碍的各种治疗方法，包括光疗、药物治疗和认知行为疗法等。因此答案是B。（本文图片均来源于网络，仅供学习交流使用，侵删）

To explain the health benefits of evening showers.B. To discuss the impact of showering on sleep quality.C. To highlight the importance of showering daily.D. To compare the advantages of morning and evening showers.Part II. TRANSCRIPTMorning shower or evening shower: Which is best? 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.

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?

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.

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.

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.

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
