推行禁烟竟如此艰难It’s Maddeningly Difficult to Ban Smoking文本难度:六级(CET-6)刘立军供稿The U.K.’s landmark generational cigarette ban, which received royal assent in April 2026 and is due to take effect in January 2027, might yield its most dramatic results decades from now, if it sticks around that long. 英国具有里程碑意义的代际禁烟法案于2026年4月获得王室批准,并将于2027年1月正式生效。英国新近出台的禁烟令若能持续落地执行,或许要在数十年后才能显现出最显著的效果。Since tobacco first arrived on the shores of England in the late 16th century, some Brits have wanted to eradicate it. Back in 1604, King James I was so alarmed about his country’s new smoking habit that he imposed a 4,000 percent tariff on the crop. That year, he wrote one of the world’s first anti-tobacco essays, declaring smoking “loathsome to the eye, hateful to the nose, harmful to the brain, dangerous to the lungs.” 自16世纪末烟草传入英国起,就有部分英国人希望彻底根除烟草。1604年,詹姆斯一世国王就对国内兴起的吸烟风气深感忧虑,于是对烟草征收税率高达4000%的关税。同年,他撰写了世界上最早的反烟草论著之一,称吸烟“触目生厌、刺鼻难闻、损伤大脑、戕害肺腑”。Despite the best efforts of the king and the generations of anti-tobacco activists who followed him, people in the United Kingdom still smoke. Now advocates are hoping a new law that prohibits anyone born on or after January 1, 2009, from ever buying cigarettes will finally end the habit for good. But the tobacco-free generation, at least in the short term, is unlikely to truly be tobacco-free. 尽管英国国王以及后世一代又一代反烟草人士竭尽全力,很多英国人至今仍在吸烟。如今,支持控烟的人士寄希望于一项新法案:该法案禁止2009年1月1日及以后出生的人购买香烟,期盼以此彻底终结这一恶习。然而,至少在短期内,这个所谓的“无烟一代”,恐怕难以真正做到完全不接触烟草。Generational tobacco bans were first proposed in 2010 by a group of researchers in Singapore. Around that time, less extreme anti-tobacco measures — such as media campaigns, clean-air laws, and taxes — had reduced smoking in many countries to such a point that public-health advocates started to seriously consider policies that could shrink rates to effectively zero. A tobacco “endgame,” as it has become known, was in sight. “I want to stamp out smoking for good,” Rishi Sunak, the former U.K. prime minister, said in a statement when he first proposed the plan in 2023. 2010年,新加坡的一个研究团队首次提出了“代际禁烟令”这一构想。当时,媒体宣传、清洁空气法案、烟草税收等相对温和的控烟措施,已将许多国家的吸烟率降至较低水平。公共卫生领域的倡导者由此开始认真研究,思考如何通过采取更为彻底的政策,将吸烟率降至接近于零。业界所说的烟草管控“终局”似乎近在眼前。2023年,英国前首相里希·苏纳克在首次提出该方案时发表声明称:“我希望彻底根除吸烟现象。”Currently, U.K. residents need to be 18 or older to purchase cigarettes. The new generational ban will introduce a more unusual paradigm: Beginning on January 1, 2027, an 18-year-old born on New Year’s Day 2009 will not be able to buy products such as cigarettes and chewing tobacco for the rest of their life. But a friend born one day earlier would face no such barrier. That means, as some critics of the ban have pointed out, that 18-year-olds will almost certainly bum cigarettes from older friends — the same way younger teens have acquired them since time immemorial. Data suggest that most adolescent British smokers get cigarettes for free from older people they know. In one study, in which researchers interviewed British smokers as young as 12 about how they obtained cigarettes, kids who waited outside of tobacco shops in hopes that an older customer would buy for them reported mostly targeting people under 25. 目前,英国居民需年满18周岁才可购买香烟。而这项全新的代际禁令将带来一种更为特殊的管控模式:自2027年1月1日起,2009年元旦出生的青年,即便年满18岁,终身都不得购买香烟、嚼烟这类烟草制品。但如果有人仅早一天出生,则不受这条禁令限制。正如该禁令的部分批评人士所指出的,这意味着这批年满18岁的年轻人几乎肯定会向年龄更大的朋友讨要香烟——古往今来,低龄青少年就是这样获取香烟的。数据表明,英国绝大多数未成年吸烟者,都是从相熟的长者手上免费拿到香烟。在一项针对低至12岁的英国吸烟青少年的研究中,研究人员询问了他们获取香烟的途径。部分青少年会守候在烟草店门外,指望年长顾客帮忙代买,据他们反馈,自己主要找25岁以下的成年人帮忙。Lawmakers included language in the bill designed to dissuade older people from buying cigarettes for their underage acquaintances. But, more importantly, that issue will likely work itself out over time. By 2034, no one under 25 will be able to purchase cigarettes. And with each passing year, kids’ sources of illegal cigarettes should progressively dwindle. Because having peers who smoke increases young people’s chances of starting themselves, fewer kids being able to get their hands on cigarettes should have a ripple effect, dissuading more and more of their peers from experimenting. By 2079, no one under 70 will be legally able to smoke. It will become the habit not of teenage rebellion but of retirement homes. 立法者在法案中增设相关条款,意在劝阻年长者不要为未成年熟人代买香烟。但更重要的是,这一问题大概率会随着时间的推移而自然化解。到2034年,25岁以下的人都将无法购买香烟。年复一年,青少年获取非法香烟的渠道也会日益萎缩。身边有吸烟的同龄人,会增加年轻人开始吸烟的概率;能够接触到香烟的青少年越来越少,将会产生连锁反应,促使更多同龄人打消尝试吸烟的念头。到2079年,70岁以下人群将不再具备合法吸烟的资格。吸烟将不再是青春期叛逆的标志,反倒会成为养老院里的一种习惯。This all depends, of course, on retailers actually following the law — a big if, according to some tobacco-control experts I spoke with. In a 2023 NHS survey, one-third of youth smokers reported regularly (and illegally) buying cigarettes from shops. “I don’t think we should play down the need for enforcement,” Nathan Davies, a doctoral fellow at the University of Nottingham who studies tobacco control, told me. And even if shopkeepers play by the rules, other people might not. Consider the small Himalayan nation of Bhutan, where all tobacco sales were banned in 2004, but cigarettes remained easy to access because a black market quickly cropped up. Those dealers didn’t serve just existing smokers but also young children. In 2019, nearly a quarter of 13-to-15-year-olds in the country used tobacco. 当然,这一切的前提是零售商能否真正遵守法律——我采访的一些控烟专家称,这还是个巨大的未知数。英国国家医疗服务体系(NHS)2023年的一项调查显示,三分之一的青少年吸烟者称自己经常(且非法地)在商店购买香烟。诺丁汉大学从事控烟研究的博士研究员内森·戴维斯表示:“我们绝不能弱化执法的重要性。”即便商家恪守规定,其他人却未必照做。以喜马拉雅山区小国不丹为例:该国2004年全面禁止烟草销售,但黑市迅速滋生,香烟依然极易获取。这些黑市商贩不仅向吸烟人士供货,甚至把魔爪伸向了青少年。2019年,该国近四分之一的13-15岁青少年使用了烟草制品。Nigel Farage, the leader of the right-wing Reform U.K. Party, has repeatedly insisted that such a black market could appear in the U.K. too. But the country’s experiment was not technically a generational tobacco ban, unlike the policy in the U.K., which was crafted to ensure that most current smokers can continue to buy their products legally, thus shrinking the profitability of any black market. The Bhutan and U.K. policies are “structurally so different in scope, sequencing, enforcement infrastructure, and market context that the comparison generates more confusion than insight,” Kashish Aneja, who leads initiatives in Asia at Georgetown University’s O’Neill Institute for National and Global Health Law, told me via email. 英国右翼改革党领导人奈杰尔·法拉奇一再提出,英国同样可能滋生这样的黑市。但严格来说,不丹的管控尝试不同于英国的代际禁烟令;而英国出台的这项政策,充分保障大多数现有吸烟者仍可合法购买烟草制品,以此压缩黑市的获利空间。乔治城大学奥尼尔国家与全球卫生法研究所亚洲区项目负责人卡希什·阿内贾在邮件中指出,不丹与英国的政策“在管控范围、实施节奏、执法配套体系以及市场环境上存在本质结构性差异,将两者进行比较,更多只会造成认知混淆,而无法带来有效借鉴”。No actual generational tobacco ban has existed for enough years to reveal its long-term effects. The Maldives, a small island nation south of India, implemented such a policy in November. Several Massachusetts towns have also passed similar bans. Brookline, a wealthy suburb of Boston, was the first, enacting its own version in 2021. Available data suggest the ban has had little effect on cigarette smoking thus far, but according to advocates, real change will take much more time. “It is a slow and gentle policy change which will result in changes over the mid and long-term,” Mark Gottlieb, the executive director of the Public Health Advocacy Institute at the Northeastern University School of Law, told me in an email. 迄今为止,还没有任何真正落地的代际禁烟令已经过足够长的时间来验证其长期成效。位于印度以南的岛国马尔代夫于去年11月实施了同类政策。美国马萨诸塞州的几个城镇也通过了类似禁令。而波士顿的富裕郊区布鲁克莱恩则走在了前列,于2021年在当地开始实施禁令。现有数据表明,该禁令迄今为止对吸烟行为的抑制作用微乎其微,但支持该政策的人士表示,实质性改变需要更长的时间。东北大学法学院公共卫生倡导研究所执行主任马克·戈特利布在给我的邮件中写道:“这是一项温和渐进的政策,其成效将在中长期逐渐显现。”New Zealand’s left-wing Labor Party passed a tobacco-free-generation policy in 2022. But the country’s new center-right coalition government, on taking power in 2024, repealed the law before it went into effect. The government’s stated reasons for the repeal were so that cigarette-tax revenue could pay for a slew of new tax cuts, and because it was argued that the policy would have fueled illegal smuggling. Something similar might happen in the U.K. Farage, himself a smoker, has called the ban “puritanical” and vowed to repeal it if his party takes power. 新西兰左翼工党于2022年通过了“无烟一代”政策。但该国新一届中右翼联合政府2024年上台后,在法案生效前就将其废除。政府给出的废除理由有两点:一是需要依靠香烟税收,支撑一揽子减税政策;二是认为该政策会助长非法走私活动。类似的情况也可能在英国上演。本身就是吸烟者的法拉奇,称这项禁令带有“清教徒式的禁欲色彩”,并扬言若其政党上台执政,必将予以废除。He’s probably not the only one who’d like to see that happen. Tobacco companies urged Parliament not to pass the law, arguing that it was discriminatory and would not prevent youth smoking — and would increase crime, to boot. “Every year from 2027 onwards a generational ban will hand more of the UK tobacco market to the serious organized criminal groups who will use the proceeds of illegal tobacco to fund activities including terrorism, weapons trading, the distribution of narcotics and people smuggling,” Japan Tobacco International, which owns a number of the most popular cigarette brands in the U.K., wrote. (In a statement, a JTI spokesperson added to that list, writing, “Illegal tobacco in the UK has been linked to organized crime, including activities such as money laundering, human trafficking, and violence.”) The tobacco industry, along with smokers’-rights groups, also aggressively courted certain U.K. conservatives as the new ban was being debated, hosting them for lunches and at least one party. 希望看到禁令被废除的恐怕不止法拉奇一人。烟草公司曾游说议会否决该法案,称其具有歧视性,不仅无法阻止青少年吸烟,还会加剧犯罪。拥有英国多个畅销香烟品牌的日本烟草国际公司(JTI)写道:“自2027年起,代际禁烟令会逐年把英国更大一部分烟草市场拱手交给大型有组织犯罪集团。这些团伙将利用非法烟草的利润,资助恐怖主义、武器交易、毒品贩运、人口走私等各类犯罪活动。”(JTI发言人在另一份声明中补充道:“英国境内的非法烟草贸易与洗钱、人口贩运和暴力等有组织犯罪活动密切相关。”)在新禁令的辩论期间,烟草行业还联合吸烟者权益组织积极拉拢部分英国保守派议员,为他们举办午餐会,以及至少一场社交派对。Despite the debate, generational smoking bans are broadly popular. A poll commissioned by the anti-smoking group Action on Smoking and Health found that 68 percent of English people support the new ban. In New Zealand, about 60 percent of voters opposed the country’s about-face. Perhaps that’s because smoking remains one of the world’s leading causes of preventable death, or because the overwhelming majority of smokers regret ever starting. The new policy might not make much difference for today’s teens, but decades from now, a new generation really might avoid that lifelong error — as long as the ban actually sticks around. 尽管争议不断,代际禁烟令仍广受民众欢迎。反吸烟组织“吸烟与健康行动”委托开展的民调显示,68%的英格兰民众支持这项新禁令。在新西兰,约60%的选民不认同禁烟政策的彻底转向。究其原因,可能是因为一方面吸烟依然是全球可预防死亡的首要诱因之一,另一方面绝大多数吸烟者对当初染上烟瘾后悔不已。这项新政策或许不会对今天的青少年产生太大影响,但几十年后的那一代人真的有可能避免犯下这个终身错误——前提是这项禁令能够切实长期推行。【词汇】1. time immemorial 太古时代,很久以前2. dissuade v. 劝阻;阻止3. dwindle v. 逐渐减少;缩小4. ripple effect 连锁反应5. doctoral adj. 博士的6. repeal v. 废除;撤销7. a slew of 大量;许多8. narcotic n. 麻醉药;毒品9. trafficking n. 非法交易,非法买卖10. publicize v. 宣传;宣扬11. proponent n. 支持者;倡导者12. about-face n.

I got about 6 and 1/2 hours of sleep. Last night, I slept four hours. I got 5 hours 45 minutes of sleep. Last night, I got about 5 hours of sleep. Usually, I try to shoot for 7 to 8. It seems like most people are not getting 8 hours of sleep. We got a wide range of answers today. I am on a mission to find out if that’s really what we need to do. And I’m bringing in a special guest, Dr. Sanjay Gupta.How are you? You missed this discussion. Oh man, you are the man I need to speak to. So why eight hours? Is this the optimal amount?optimal adj. 最佳的,最适宜的(Q1) So you know, like most things in life, it’s an average. The average is a range between 6 and 10 hours for most adults. The thing is, for kids, it’s actually even more than that—9 to 12 hours for elementary school kids and teenagers, back to sort of 8 to 10 hours.(Q5-1) Take us inside of our brains. What happens while we sleep?Sleep is actually a really fascinating time for the brain. It’s kind of interesting because people think it’s just at rest. It’s actually really active. And there are several stages of sleep. (Q2) Stage one, you spend about 5% of your time in stage one. That’s the lightest sleep, just sort of drifting off to sleep. Then stage two, a little bit deeper. About 45% of your sleep is stage two. Then there’s stage three, which is the most restful, about 25%. And then there’s this really interesting stage. It’s called REM—rapid eye movements. Literally, your eyes are moving behind your eyelids, and that’s when you’re dreamy. Yeah. And you cycle over and over again through these stages of sleep. About 90 minutes or so for all the stages.The other thing your brain is doing is clearing out waste from all the work that it’s done during the day. (Q3) And I think most importantly for students, that’s the time you take memories and experiences from your day and you put them in the long-term memory stores so you can remember these months, years down the road.So how do I know if I’ve gotten enough sleep for me, for my body?So, most people generally know because you are probably a little bit grumpier than you normally are. You’re always cheery though, aren’t you? I’ve never seen you grumpy. You know, you feel tired. I think one of the biggest tests—someone told me this years ago—is if you put yourself in a darkened room in a comfortable chair and right away you fall asleep within a couple of minutes; that’s a pretty sure sign that you’re sleep-deprived.grumpy adj. 脾气坏的,易怒的(Q5-2) So, give your boy some tips and all of us on getting great sleep.So, you’re an athlete, probably working out too close to when you go to bed; it’s probably going to keep you up. You’re sort of stimulating the body. Caffeine stimulates the body. So, in the morning, good idea. But later on in the afternoon, that’s probably going to keep you up. Screens, the blue light alone is something that’s going to keep you up. It just kind of wakes your brain up. Kind of wakes your brain up. Yeah. It’s like, hey, time to wake up. Time to actually do something.caffeine n. 咖啡因I think the biggest thing is the idea of sleeping around the same time and waking up at the same time every day. It’s like you’re confusing your brain. (Q4) If you go to bed 2 hours early or 2 hours later, your brain’s like, “Wait a second. Is it time to sleep or is it not time to sleep? I’m not sure.” If you get into a consistent pattern of whatever time, so let’s say 11 to 7, uh, every day, you’re likely to get good sleep. Your brain’s not confused, and you can stick with that pattern.Is that connected to that circadian rhythm we always have?circadian adj. 生理节律的And your circadian rhythm can get sort of messed up very quickly. You see that when you travel to LA or, you know, any kind of jet lag? You can essentially put yourself into jet lag right at home by confusing your brain like that all the time if you do nothing else. Well, get rid of the screens for sure, but after that, go to bed at the same time, wake up at the same time.You know my tip for great sleep? Hang out with people who just put you at ease. And for me, you’re one of those people. You’re the best sleep. You’re the best.I’m not sure. It’s good that I put you to sleep.Part III. KEYQ1. C.【解析】细节题。题目出处为:“So you know, like most things in life, it’s an average. The average is a range between 6 and 10 hours for most adults.” 意为:“就像生活中的很多事情一样,八小时只是一个平均值。对于大多数成年人来说,平均睡眠时间范围是6到10小时。”该句表明“八小时睡眠”并非绝对标准,而是一个平均参考值,因此正确答案为C。Q2. B.【解析】细节题。题目出处为:“Then stage two, a little bit deeper. About 45% of your sleep is stage two.” 意为:“第二阶段睡眠更深一些,大约占全部睡眠时间的45%。”结合前文“Stage one, you spend about 5% of your time in stage one”以及后文“Then there’s stage three, which is the most restful, about 25%”可知,第二阶段占比最高,因此正确答案为B。Q3. C.【解析】细节题。题目出处为:“And I think most importantly for students, that’s the time you take memories and experiences from your day, and you put them in the long-term memory stores so you can remember these months, years down the road.” 意为:“我认为,对学生来说最重要的是,睡眠期间你的大脑会把白天的记忆和经历储存到长期记忆中,以便未来数月甚至数年后仍能记住。”该句直接说明了睡眠对学生的重要意义,因此正确答案为C。Q4. B.【解析】推理题。题目出处为:“If you go to bed 2 hours early or 2 hours later and your brain’s like, ‘Wait a second. Is it time to sleep or is it not time to sleep? I’m not sure.’” 意为:“如果你提前两小时或推迟两小时睡觉,你的大脑就会想:‘等等,现在是该睡觉的时候,还是不该睡?我也不确定’。”由此可以推断,不规律的睡眠习惯会扰乱人体自然生物节律,因此正确答案为B。Q5. D.【解析】主旨题。题目出处为:“Take us inside of our brains. What happens while we sleep?”以及“… give your boy some tips and all of us on getting great sleep.” 主持人请Gupta博士解释睡眠期间大脑的活动并提供改善睡眠的建议,随后他们对睡眠阶段、大脑功能、记忆形成以及健康睡眠习惯进行了详细讨论,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)

双语阅读 | 用运动对抗抑郁和焦虑能否等同于正规治疗?

用运动对抗抑郁和焦虑能否等同于正规治疗?Is exercise as effective as treatments for depression and anxiety?文本难度:六级刘立军供稿Is exercise as effective as treatments for depression and anxiety? Some big studies say yes. Many experts have reservations. 运动对抗抑郁、抗焦虑的疗效,能和正规治疗相媲美吗?一些大型研究给出了肯定的答案,但许多专家对此仍持保留意见。For those in the doldrums, few things are more tiresome than being told to exercise. But unwelcome advice is not necessarily wrong. Study after study has found that exercise boosts mood and reduces anxiety. Two large analyses published earlier this year go further, suggesting it works about as well as therapy or antidepressants. 对于那些正处于情绪低谷的人来说,几乎没有比听到别人劝自己“去运动”更让人心烦的了。但不中听的建议未必就是错的。一项又一项的研究发现,运动能够提振情绪,缓解焦虑。今年早些时候发表的两项大型分析进一步表明,运动的治疗效果与心理治疗、抗抑郁药物不相上下。The first, published in January by researchers based across Britain and Ireland, took the form of a Cochrane review — a well-regarded meta-analysis of health-care research. It pooled the results of 69 randomized-controlled trials (RCTs) conducted to measure the effects of exercise on depression. The second paper, published in February in the British Journal of Sports Medicine, was a so-called meta-meta-analysis. It drew on more than 1,000 trials involving nearly 80,000 participants. Both concluded that exercise reduces symptoms of depression and anxiety by roughly as much as conventional treatments. 第一项研究由英国和爱尔兰的研究人员完成,于今年1月发表,采用了备受推崇的科克伦(Cochrane)系统评价形式——这是医疗领域广受认可的一种荟萃分析。该研究汇总了69项随机对照试验(RCTs)的数据,这些试验专门用来评估运动对抑郁症的作用。第二篇论文于2月发表在《英国运动医学杂志》上,采用了所谓的“二次荟萃分析”。研究参考了1000余项试验,受试者近8万名。两项研究均得出结论:运动在缓解抑郁、焦虑症状方面的效果,与常规治疗方法大致相当。There are important caveats. Meta-analyses are only as good as the studies they include, and exercise trials are prone to being skewed. For one thing, participants cannot be blinded — they know if they are doing kettlebell swings or not — which makes their self-reported mood vulnerable to any favorable expectations they might have. For this and other reasons, the Cochrane review judged all the studies it included to be at “high risk” of bias. 但该结论存在重要的限定条件。荟萃分析的可靠性完全取决于所纳入的原始研究,而运动类试验往往容易出现结果偏倚。首先,参与者无法实施“盲法”——自己是否完成壶铃摇摆这类运动,参与者心知肚明。这就导致参与者主动上报的情绪,很容易受到内心积极预期的影响。出于上述及其他因素,这份科克伦系统评价判定,其纳入的所有研究均存在“高偏倚风险”。What’s more, the meta-meta-analysis did not include any studies that tested exercise against other interventions. The findings from the exercise trials were, instead, compared against those from separate trials of antidepressants or therapy. But unlike exercise studies, RCTs of antidepressants are typically well blinded and have strong placebo effects, making it harder for them to achieve similarly impressive results. “I don’t think it’s a fair comparison,” says Jonathan Roiser, a professor of neuroscience at University College London. 此外,这项“二次荟萃分析”并未纳入任何将运动与其他干预措施进行直接对比的研究。它是把运动试验的结果,与另外独立开展的抗抑郁药、心理治疗试验的数据做比对。但与运动研究不同,抗抑郁药物的随机对照试验通常盲法设计完善,且安慰剂效应显著,这使得药物想要取得同样令人瞩目的疗效数据难度更大。伦敦大学学院的神经科学教授乔纳森·罗伊泽(Jonathan Roiser)表示:“我认为这样对比并不客观。”All the same, most researchers are confident that exercise helps improve mood. Aerobic workouts, such as running, walking or cycling, seem to be particularly beneficial across the board. For depression, group-based or supervised exercise is more effective than sweating alone, and the benefits of exercise accrue over several months. For anxiety, the best results seem to come from lower-intensity activity. 尽管如此,绝大多数研究人员仍认可运动有助于改善情绪。跑步、散步或骑车等有氧运动,总体来看大有裨益。针对抑郁症,团体运动或在专业人员指导下开展的运动,效果优于独自锻炼,且运动带来的益处会数月里不断累积。而对于焦虑症,低强度运动似乎能带来最佳效果。Why exercise works is less clear. The popular idea that exercise generates a “high” by causing the release of endorphins, a form of opioid, has little scientific support. A study published in 2021 found that blocking runners’ opioid receptors reduced neither the euphoria they reported after a session nor the drop in anxiety. Researchers instead think that endocannabinoids — chemicals produced by the body and brain that activate the same receptors as the active molecules in cannabis — might be responsible for these short-term boosts. 至于运动为何有效,具体机制尚不明确。有一种广为流传的说法:运动会促使内啡肽(一种阿片样物质)的释放,从而让人产生愉悦感,但这一说法缺乏足够的科学依据。2021年的一项研究发现,阻断跑步者体内的阿片类受体,既不会降低他们运动后的欣快感,也不会减弱焦虑的缓解程度。研究人员转而认为,内源性大麻素可能是带来这种短期情绪提升的原因;这类物质由人体和大脑合成,能激活与大麻有效成分相同的受体。Other pathways are also being triggered. Exercise seems to reduce inflammation and improve brain plasticity, as well as increasing the transmission of dopamine in the brain. Dopamine is involved in the process of weighing effort against reward, and so increasing transmission may help reverse the loss of motivation associated with depression. 运动还会激活其他生理机制:它能够减轻炎症,提升大脑可塑性,并增加大脑内多巴胺的传递。多巴胺参与了“权衡付出与回报”这一心理过程,因此,增加多巴胺的传递有助于改善抑郁症患者典型的动力缺失问题。There are purely psychological benefits, too: exercise can provide people with a sense of achievement, agency and eventually mastery, all of which are known to lift mood. Plenty of reasons, then, to work up a sweat. 此外,运动还能带来纯粹的心理益处:它能给人带来成就感、自主感,最终获得一种掌控感,而这些都能够提振情绪。如此看来,我们完全有理由动起来,好好出一身汗。 【词汇】 1. in the doldrums 情绪低落2. meta-analysis n. 荟萃分析(一种循证医学研究方法,把多个独立的同类研究的数据汇总、合并分析,得到一个综合性结论,研究说服力高于单一试验)3. caveat n. 警告;提醒4. skew v. 使……有偏差;影响……的准确性5. placebo n. 安慰剂6. neuroscience n. 神经科学7. aerobic adj. 有氧的8. accrue v. 积累;增加9. endorphin n. 内啡肽10. opioid n. 阿片样物质(既可来源于外界毒品,也包含人体自身合成的内啡肽,能够起到镇痛、产生欣快感的作用)11. receptor n. 受体;感受器12. euphoria n. 欣快感;极度愉快13. cannabis n. 大麻14. inflammation n. 炎症15. dopamine n. 多巴胺(本文图片来源于摄图网,版权归摄图网所有)

Life is getting in the way, and you’ve slipped into old habits… snoozing your alarm and eating chocolate for breakfast. Sound familiar?zest n. 热情,兴趣 podcast n. 播客,音频节目 commute n. 通勤,往返于工作地点和住所之间 Don’t be hard on yourself. It’s unrealistic to rely on willpower alone. (Q1) As James Clear, author of the bestselling book Atomic Habits, writes, “The problem isn’t you. The problem is your system.” Our habits come from goals, so start by getting really clear. Goals, according to George T Doran, should be SMART: specific, measurable, achievable, relevant and time-bound. It’s not enough to say, “I’ll exercise more” – that’s too vague! (Q2) A SMART goal would be “I’m going to walk for 20 minutes in the evenings on weekdays.” Now you have a clear action that you can stick to.vague adj. 模糊的,不明确的 Once you’re clear on your goals, you need to make the associated habits as automatic as possible. (Q3) Try ‘habit stacking’, a technique popularised in the book Atomic Habits, which involves attaching a new habit onto something you already do regularly. For example, if you already make coffee every morning, use that moment to read your book for 20 minutes. That way, your new reading habit is now intertwined with something you’re going to do anyway. Another key strategy is to reward yourself, to transform the habit from a chore into something pleasurable. If it’s hard to get yourself to the gym, promise yourself that after each visit, you’ll allow yourself a treat – a takeaway meal or an episode of your favourite TV show.stack v. 堆叠,堆积 (Q4) Even with our best intentions and a great system, stress and interruptions to your routine like social events can still make keeping habits feel like an uphill battle. If or when you have setbacks, accept it as part of the process. Life is full of spontaneity and uncertainty – one could argue that’s what keeps it interesting! Use setbacks as a pause for reflection and review. What about your system is working? What’s no longer serving you? Then, get back on track.spontaneity n. 自发性,自然性 Part III. KEYQ1. C.【解析】细节题。根据“As James Clear, author of the bestselling book Atomic Habits, writes, “The problem isn’t you. The problem is your system.” ”,可知詹姆斯·克利尔认为,人们无法坚持好习惯,问题不在于人本身,而在于自身的体系存在缺陷。因此正确答案为C。Q2. B.【解析】细节题。根据“A SMART goal would be “I’m going to walk for 20 minutes in the evenings on weekdays.””,可知一个SMART目标可以是“我打算在工作日的晚上步行20分钟。”因此正确答案为B。Q3. D.【解析】细节题。根据“Try ‘habit stacking’, a technique popularised in the book Atomic Habits, which involves attaching a new habit onto something you already do regularly.”,可知habit stacking是指“习惯叠加”,即将一个新习惯附加到你已经经常做的事情上。因此正确答案为D。Q4. B.【解析】推理题。根据“Even with our best intentions and a great system, stress and interruptions to your routine like social events can still make keeping habits feel like an uphill battle. If or when you have setbacks, accept it as part of the process.”,可知即使我们有最好的意图和很好的系统,压力和社交活动等对日常生活的干扰仍然会让保持习惯感觉像是一场艰难的战斗。在培养习惯的过程中遭遇挫折是过程的一部分。因此正确答案为B。Q5. A.【解析】主旨题。整篇文章的核心内容是讨论如何通过明确目标、习惯叠加和奖励机制等策略来建立和维持长期的习惯。“Small steps to build long-lasting habits” 的标题以及文章内容都围绕这一主题展开,因此正确答案为A。(本文图片来源于摄图网,版权归摄图网所有)

TRANSCRIPTThe tobacco trapVGS: There is an industry that spends over a million dollars an hour on advertising. And they’re constantly looking for younger and newer consumers. Do you know why? Because they know that their product kills up to half of its users. (Q1) We are talking about the tobacco industry today and our expert is Simone St. Claire. Welcome, Simone. So we know that there are no safe tobacco products, right, whether it’s shisha, chewing tobacco, rolled cigarettes. So how is it that the tobacco industry is succeeding in selling us death and destruction continuously?SSC: Great question. (Q2) The tobacco industry is well aware that their products kill around eight million people globally every year. To sustain their business, they must continuously recruit new users to replace those who die from using their products. And because their products are so harmful, they must do everything they can to make them attractive, especially to young people. One of their biggest tactics is flavours. If you think about it, tobacco on its own is harsh and unappealing. But when you add mint, mango, bubblegum or vanilla, they seem less dangerous. (Q3) Flavours are meant to hook you and then keep you addicted. This is not by accident, this is by design. Research shows that flavours are one of the main reasons that children and young people start using nicotine and tobacco products and once they start, they become addicted quickly.mint n. 薄荷 vanilla n. 香草 VGS: So just like flavours, there is research that shows packaging can attract consumers to products, right? How does the tobacco and nicotine industry use packaging to attract younger and younger people and women, especially?SSC: Tobacco companies use minimalist designs and bright colours to make their products look premium or even clean. But as you mentioned, there is no such thing as a safe tobacco product. Let’s take slim cigarettes, for example. (Q4) These are cigarettes that are designed with narrower dimensions and traditionally marketed to women. They’re often associated with sophistication and elegance and are wrongly perceived to be less dangerous. But in reality, they pose comparable risks to regular cigarettes. Then if we look at the more recent nicotine products, sleek, colourful and high-tech. To be clear, when we’re talking about nicotine products, the most common is e-cigarettes, also known as vapes. (Q5-3) E-cigarettes are designed to look like USB sticks, lipsticks and stylish gadgets, which are easy to disguise and conceal from parents and teachers, which is particularly concerning when it comes to children and young people.premium adj. 高端的,优质的 sophistication n. 精致sleek adj. 光滑的,时尚的 VGS: So we know that most people who consume tobacco products know that it is harming their body but let’s go over it again. How exactly does tobacco impact our body?SSC: Tobacco use harms nearly every organ of the body. It causes heart disease, respiratory conditions, and over 20 types of cancer, including lung cancer. Tobacco is a major risk factor for noncommunicable diseases (NCDs) and premature death. But the good news is that the benefits of quitting can be felt almost immediately. Within 20 minutes, blood pressure and heart rate drop. Within two to 12 weeks, lung function and circulation improves. Within a year, the risk of heart disease is cut in half and over time, the risk of tobacco-related diseases decreases dramatically.respiratory adj. 呼吸的 VGS: Another interesting fact here is the plain packaging or graphic warnings that you often see on cigarette boxes, that’s actually a result of the work that WHO and partners have done to bring in those policies to inform consumers about the dangers of tobacco. So let’s talk about another tactic and that’s advertising. You see tobacco advertising in music concerts, in sports events. Talk to us about that.SSC: Exactly, the marketing budget of big tobacco is larger than the GDP of some countries. They spend tens of billions of dollars every year to hide the truth that tobacco kills. (Q5-1) They use social media influencers, music festivals and giveaways to promote their harmful and addictive products. They use cartoon-like branding and sleek advertising to attract young users and (Q5-2) you’ll notice in some stores, they place nicotine and tobacco products near candy, which leads children to believe that they are innocent or even exciting.VGS: Simone, how can public health agencies, like WHO, stand up to the tobacco industry, which seems to have massive resources, right?SSC: Science, evidence and awareness is key. The more people know about these tricks, the less effective they become. We need to ensure that people are aware of just how harmful tobacco products are and how they destroy families and lives. WHO and countries are working together to put in place public health policies, things like smoke-free public places, bans on advertising, making products less affordable by introducing taxes and putting graphic images and health warnings on product packaging. And latest data shows that more than five billion people around the world are protected by at least one of these measures. This is a result of strong and decisive regulatory action. As a consumer, don’t be fooled. If nicotine or tobacco products look fun, tasty or trendy, they’re designed that way to hook you. So spread the word and support policies that protect public health.decisive adj. 决定性的,果断的 VGS: Thank you, Simone. That was Science in 5 today. Until next time then, stay safe, stay healthy and stick with science.Part III. KEYQ1. A.【解析】主旨题。根据“Today we are talking about the tobacco industry...”以及文章中多次提到烟草行业的策略和手段,可知此文主要讨论了烟草行业如何通过各种方式吸引用户并维持其业务。因此正确答案为A。 Q2. B.【解析】细节题。根据“The tobacco industry is well aware that their products kill around eight million people globally every year.”,可知全球每年约 800 万人因烟草制品死亡。因此正确答案为B。 Q3. C.【解析】推理题。根据“Flavours are meant to hook you and then keep you addicted. This is not by accident, this is by design.”,可知添加口味是有意设计的,目的是使人让人上瘾并保持依赖。由此可以推断,烟草行业故意使用口味来吸引年轻用户,因此正确答案为C。 Q4. B.【解析】词汇题。根据“These are cigarettes that are designed with narrower dimensions and traditionally marketed to women. They’re often associated with sophistication and elegance and are wrongly perceived to be less dangerous.”,可知这些香烟设计得更细,传统上销售给女性。它们通常与优雅联系在一起,在这一语境中,sophistication与优雅相关,指指精致、高雅。因此正确答案为B。 Q5. D.【解析】细节题。根据“They use social media influencers, music festivals and giveaways to promote their harmful and addictive products.” 和“You’ll notice in some stores, they place nicotine and tobacco products near candy, which leads children to believe that they are innocent or even exciting.” 以及“E-cigarettes are designed to look like USB sticks, lipsticks and stylish gadgets, which are easy to disguise and conceal from parents and teachers.” 这些句子分别说明了A、B和C选项的内容,而文中未提到烟草行业通过减少烟草的有害影响作为策略,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)

I got about 6 and 1/2 hours of sleep. Last night, I slept four hours. I got 5 hours 45 minutes of sleep. Last night, I got about 5 hours of sleep. Usually, I try to shoot for 7 to 8. It seems like most people are not getting 8 hours of sleep. We got a wide range of answers today. I am on a mission to find out if that’s really what we need to do. And I’m bringing in a special guest, Dr. Sanjay Gupta.How are you? You missed this discussion. Oh man, you are the man I need to speak to. So why eight hours? Is this the optimal amount?optimal adj. 最佳的,最适宜的(Q1) So you know, like most things in life, it’s an average. The average is a range between 6 and 10 hours for most adults. The thing is, for kids, it’s actually even more than that—9 to 12 hours for elementary school kids and teenagers, back to sort of 8 to 10 hours.(Q5-1) Take us inside of our brains. What happens while we sleep?Sleep is actually a really fascinating time for the brain. It’s kind of interesting because people think it’s just at rest. It’s actually really active. And there are several stages of sleep. (Q2) Stage one, you spend about 5% of your time in stage one. That’s the lightest sleep, just sort of drifting off to sleep. Then stage two, a little bit deeper. About 45% of your sleep is stage two. Then there’s stage three, which is the most restful, about 25%. And then there’s this really interesting stage. It’s called REM—rapid eye movements. Literally, your eyes are moving behind your eyelids, and that’s when you’re dreamy. Yeah. And you cycle over and over again through these stages of sleep. About 90 minutes or so for all the stages.The other thing your brain is doing is clearing out waste from all the work that it’s done during the day. (Q3) And I think most importantly for students, that’s the time you take memories and experiences from your day and you put them in the long-term memory stores so you can remember these months, years down the road.So how do I know if I’ve gotten enough sleep for me, for my body?So, most people generally know because you are probably a little bit grumpier than you normally are. You’re always cheery though, aren’t you? I’ve never seen you grumpy. You know, you feel tired. I think one of the biggest tests—someone told me this years ago—is if you put yourself in a darkened room in a comfortable chair and right away you fall asleep within a couple of minutes; that’s a pretty sure sign that you’re sleep-deprived.grumpy adj. 脾气坏的,易怒的(Q5-2) So, give your boy some tips and all of us on getting great sleep.So, you’re an athlete, probably working out too close to when you go to bed; it’s probably going to keep you up. You’re sort of stimulating the body. Caffeine stimulates the body. So, in the morning, good idea. But later on in the afternoon, that’s probably going to keep you up. Screens, the blue light alone is something that’s going to keep you up. It just kind of wakes your brain up. Kind of wakes your brain up. Yeah. It’s like, hey, time to wake up. Time to actually do something.caffeine n. 咖啡因I think the biggest thing is the idea of sleeping around the same time and waking up at the same time every day. It’s like you’re confusing your brain. (Q4) If you go to bed 2 hours early or 2 hours later, your brain’s like, “Wait a second. Is it time to sleep or is it not time to sleep? I’m not sure.” If you get into a consistent pattern of whatever time, so let’s say 11 to 7, uh, every day, you’re likely to get good sleep. Your brain’s not confused, and you can stick with that pattern.Is that connected to that circadian rhythm we always have?circadian adj. 生理节律的And your circadian rhythm can get sort of messed up very quickly. You see that when you travel to LA or, you know, any kind of jet lag? You can essentially put yourself into jet lag right at home by confusing your brain like that all the time if you do nothing else. Well, get rid of the screens for sure, but after that, go to bed at the same time, wake up at the same time.You know my tip for great sleep? Hang out with people who just put you at ease. And for me, you’re one of those people. You’re the best sleep. You’re the best.I’m not sure. It’s good that I put you to sleep.Part III. KEYQ1. C.【解析】细节题。题目出处为:“So you know, like most things in life, it’s an average. The average is a range between 6 and 10 hours for most adults.” 意为:“就像生活中的很多事情一样,八小时只是一个平均值。对于大多数成年人来说,平均睡眠时间范围是6到10小时。”该句表明“八小时睡眠”并非绝对标准,而是一个平均参考值,因此正确答案为C。Q2. B.【解析】细节题。题目出处为:“Then stage two, a little bit deeper. About 45% of your sleep is stage two.” 意为:“第二阶段睡眠更深一些,大约占全部睡眠时间的45%。”结合前文“Stage one, you spend about 5% of your time in stage one”以及后文“Then there’s stage three, which is the most restful, about 25%”可知,第二阶段占比最高,因此正确答案为B。Q3. C.【解析】细节题。题目出处为:“And I think most importantly for students, that’s the time you take memories and experiences from your day, and you put them in the long-term memory stores so you can remember these months, years down the road.” 意为:“我认为,对学生来说最重要的是,睡眠期间你的大脑会把白天的记忆和经历储存到长期记忆中,以便未来数月甚至数年后仍能记住。”该句直接说明了睡眠对学生的重要意义,因此正确答案为C。Q4. B.【解析】推理题。题目出处为:“If you go to bed 2 hours early or 2 hours later and your brain’s like, ‘Wait a second. Is it time to sleep or is it not time to sleep? I’m not sure.’” 意为:“如果你提前两小时或推迟两小时睡觉,你的大脑就会想:‘等等,现在是该睡觉的时候,还是不该睡?我也不确定’。”由此可以推断,不规律的睡眠习惯会扰乱人体自然生物节律,因此正确答案为B。Q5. D.【解析】主旨题。题目出处为:“Take us inside of our brains. What happens while we sleep?”以及“… give your boy some tips and all of us on getting great sleep.” 主持人请Gupta博士解释睡眠期间大脑的活动并提供改善睡眠的建议,随后他们对睡眠阶段、大脑功能、记忆形成以及健康睡眠习惯进行了详细讨论,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)

第12届教学大赛商务英语组特等奖潘紫萌说课

说课点评:在30分钟的准备时间里,读完、理解一篇800多词的商务英语文章,记住文章的结构和要点,设计出一套有理论指导、教学理念清晰、目标合理、结构完整、方法得当,最好再带点创新的教学方案,然后在10分钟的时间里,用英语条理清晰地把它展示出来,这对任何商务英语教师来讲都是一项重大的挑战。潘紫萌老师首先分析了课文,根据内容将其解构成三大部分。选手将第二部分(第3-8段)归纳成 promotion, price and place 和将第三部分(第9段)归纳成对计划进入中国市场的外国企业的忠告,这都是正确的。但是,她把第一部分(第1-2段)归纳成product,进而把前两部分归纳成营销学中著名的4P战略,这种做法有待商榷。因为课文的第1段主要讲两个问题:1)营销战略如何在中国成功,2)这些战略如何根据中国人的喜好以及对产品或服务的认知进行调整,而不是具体的产品。也许是准备的时间非常紧迫,选手对课文的理解和归纳出现了偏差。然后,潘老师分析了学生的特点。在教学模式上,她采取以学生为中心、以产出为导向的教学模式。其教学目标包括商务英语知识、商务技能和伦理价值。在具体的教学方法上,她例举了基于任务的教学、基于讨论的教学、案例教学、学生参与的测评等,并强调要综合利用线上线下教学资源。在学习测评上,她采用师生共同参与的方式,以增强教学效果。至于具体的教学步骤,她采用BOPPPS模式,再加课后作业。以上教学方案应该说中规中矩,显示出潘老师对商务英语教学的理论、模式、方法和测评等各要素有比较全面的了解。潘老师最亮眼的表现是在10分钟的时间里,用流利的英语将其教学方案展现出来,而且条理清晰,相关的教学理论、教学方法、商务知识、商务案例均了然于胸,信手拈来,同时口到手到,同步将所讲内容写到白板上,手起笔落,一气呵成。在提问阶段,潘老师的表现依旧出色,理解到位,回答中肯,表现出较高的英语基本功和商务、人文素养。不过有的回答可以再精炼一些。比如在回答第一个问题时,把EGP,EOP,EAP,ESP 的定义都讲了一遍,有点啰嗦。总而言之,潘紫萌在说课中表现突出,是一位素质比较全面、经验比较丰富的优秀商务英语教师。点评专家:陈准民
