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.

They should be considered a useful but preliminary result.B. They should guide people to exercise exactly 8,500 steps.C. They should replace traditional weight loss advice.D. They should be applied to every adult immediately.Part II. TRANSCRIPTHow many daily steps can help keep weight off?(Q1) A new study suggests that increasing daily step counts may help people maintain weight loss in the long term, and a goal to shoot for may be around 8,500 steps a day.(Q2) The research, published in the International Journal of Environmental Research and Public Health and presented last week at the European Obesity Conference, analyzed data from 18 previous studies looking at weight loss and physical activity.(Q3) Researchers found that walking more was not strongly linked to losing additional weight during active weight loss programs. However, people who continued taking more steps each day were more likely to keep the weight off over time.Over an average follow-up period of about 1.5 years, researchers found participants maintained roughly 1% of weight loss for every additional 1,000 steps they walked daily, with the average participant starting at about 7,400 steps per day at baseline.The study noted that an average of 8,500 daily steps appeared to help participants maintain weight loss the longest, though researchers stressed that it is not a strict target or prescription for everyone.prescription n. 处方;建议;规定The increased activity happened as part of structured lifestyle programs that also included diet changes and behavioral counseling.“This was a lifestyle modification program, and it really is a multifactorial approach when it comes to weight loss. So these individuals got diet and behavioral counseling in addition to really moving more. And so you really need all of that,” ABC News medical contributor Dr. Tara Narula said on “Good Morning America” Monday.multifactorial adj. 多因素的;由多种因素造成的(Q5) Narula noted that researchers described the findings as “hypothesis-generating” and said more research is needed.“The researchers say, look, this is really hypothesis-generating; it should push us to do more research,” she explained. “It is not a prescription that everyone should go out and now do 8,500 steps. But it is helpful information.”(Q4) Researchers concluded that calorie restriction was likely more impactful during the weight loss phase, while higher levels of physical activity were more closely tied to long-term weight loss maintenance.The study also had several limitations. The analysis only included adults who were overweight or obese and relied on pooled population data, meaning the findings show correlation rather than direct cause and effect.correlation n. 相互关系;关联“Certainly if you’re planning to do a weight loss program, talk to your doctor about what is right for you in terms of your movement and goals overall,” Narula said. “And healthy habits build on each other. The more you lose weight, the more you want to exercise, and you feel better. But it really is helpful to know that just that little bit of increase might be all you need.”Part III. KEYQ1.C.【解析】细节题。题目出处为:“A new study suggests that increasing daily step counts may help people maintain weight loss in the long term, and a goal to shoot for may be around 8,500 steps a day.” 意为:“一项新的研究表明,增加每日步数或许有助于长期保持减重效果,建议将每日步数目标设置为每天8500步左右。”该句直接给出了研究所建议的步数目标,因此正确答案为C。Q2.B.【解析】细节题。题目出处为:“The research, published in the International Journal of Environmental Research and Public Health and presented last week at the European Obesity Conference, analyzed data from 18 previous studies looking at weight loss and physical activity.” 意为:“这项研究发表在《国际环境研究与公共健康期刊》上,并于上周在欧洲肥胖大会上做了报告。研究分析了此前18项探讨减重和身体活动关系的相关数据。”该句明确说明研究的数据来源,因此正确答案为B。Q3.D.【解析】细节题。题目出处为:“Researchers found that walking more was not strongly linked to losing additional weight during active weight loss programs.” 意为:“研究人员发现,在减重计划进行阶段,多走路与进一步减轻体重之间并没有很强的联系。”由此可知,在减重过程中增加步数并不会显著带来额外的减重效果,因此正确答案为D。Q4.B.【解析】推理题。题目出处为:“Researchers concluded that calorie restriction was likely more impactful during the weight loss phase, while higher levels of physical activity were more closely tied to long-term weight loss maintenance.” 意为:“研究人员得出结论,在减重阶段限制热量摄入的作用可能更为显著,而更高强度的运动则与长期维持减重成果关系更为密切。”由此可以推断,运动对于维持长期减重更为有效,因此正确答案为B。Q5.A.【解析】观点题。题目出处为:“Narula noted that researchers described the findings as ‘hypothesis generating’ and said more research is needed.” 意为:“纳鲁拉指出,研究人员将这些发现定性为‘生成假说’性质,并强调仍需要进一步研究。” 该句表明研究结果具有一定参考价值,但仍属于初步发现,需要进一步研究验证,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)

猫薄荷为何让猫“疯狂”?

猫薄荷为何让猫“疯狂”?Why Does Catnip Make Cats Go Crazy?文本难度:考研刘立军供稿Of the many bewildering behaviors cats display, one of the strangest is their obsession with a specific species of plant. After just one whiff, even the most stoic cat can start pawing, drooling, biting, and wriggling in a state of pure feline euphoria. So, why do cats go crazy for catnip? This is the question cat behavior expert Masao Miyazaki and chemist Toshio Nishikawa set out to answer in 2013. Along with their research teams from Iwate and Nagoya University, they began by studying silvervine – a plant that sparks a similar response to catnip.猫咪有着许多令人费解的行为,其中最奇特的莫过于对某一特定植物的痴迷。即便是最冷静自持的猫,哪怕只是闻上一口,也会瞬间陷入抓挠、流口水、啃咬、翻滚的状态,沉浸在纯粹的猫咪欢愉中。那么,猫咪究竟为什么会为猫薄荷神魂颠倒?2013年,猫咪行为学家宫崎正夫与化学家西川俊夫便带着这一问题展开了研究。他们与来自岩手大学与名古屋大学的研究团队携手,先从木天蓼这种植物入手——这是一种同样能在猫身上引发和猫薄荷相似反应的植物。First, the researchers painstakingly extracted chemical compounds from the plant and dribbled various combinations of them onto filter paper. Then they brought in some cats and studied which compounds they were drawn to. Overwhelmingly, their feline testers pounced on the papers containing nepetalactol. And when Miyazaki and his student Reiko Uenoyama ran blood tests on the cats who’d interacted with nepetalactol, they found their systems were flooded with endorphins. These hormones block pain signals, relieve stress, and generally create a happy, calming effect. And catnip triggers the same endorphin rush with a similar chemical called nepetalactone, and it’s this flood of happy hormones that gives catnip and silvervine their signature drug-like response.研究人员先是费尽心力,从木天蓼中提取各类化合物,再把不同配比的提取物滴在滤纸上。随后,他们找来猫咪,观察哪些化学成分会吸引它们。结果显而易见,绝大多数受试猫咪都径直扑向含有荆芥内酯醇(nepetalactol)的滤纸。宫崎正夫和他的学生上野山怜子对接触过荆芥内酯醇的猫咪进行血液检测,发现它们体内会大量分泌内啡肽。这类激素能够阻断痛觉信号、缓解压力,带来愉悦、镇定的感受。而猫薄荷则是借助一种结构相近的物质——荆芥内酯,同样能刺激猫体内大量释放内啡肽。正是这种快乐激素的迸发,让猫薄荷和木天蓼产生了标志性的、类似药物带来的反应。These compounds don’t just trigger this effect in small cats. When the researchers brought nepetalactol-treated filter paper to a few zoos, leopards, lynxes, and jaguars all dove face-first into the compound. This was big news. If these different cat species reacted to nepetalactol the same way, the response was likely a shared evolutionary trait, potentially something important to cat survival that stretched back millions of years. When the silvervine researchers presented their work at a conference, one evolutionary biologist raised a compelling theory. In chemical terms, both nepetalactol and nepetalactone are classified as iridoids – a type of natural compound known to contain insect-repelling properties. So perhaps cats rubbing their faces in silvervine and catnip were applying an ancient form of bug spray.这类化合物并非只对小型猫科动物生效。当研究人员把滴有荆芥内酯醇的滤纸带到几家动物园时,豹子、猞猁和美洲豹全都一头埋上去嗅闻。这是一项重大发现。既然这么多不同种类的猫科动物都对荆芥内酯醇产生相同反应,说明该行为极有可能是共有的进化特征,或许关乎猫科动物生存的重要本能,其根源可追溯至数百万年前。当木天蓼研究团队在学术会议上展示成果时,一位进化生物学家提出了一个极具说服力的假说:从化学分类来看,荆芥内酯醇与荆芥内酯都属于环烯醚萜类化合物,这类天然物质具备驱虫特性。所以,猫咪把脸在木天蓼和猫薄荷上蹭来蹭去的行为,或许正是在涂抹一种古老的驱虫剂。To test this, researchers set up cages of mosquitoes that cats could stick their heads into. And sure enough, the cats that had been treated with nepetalactol got fewer mosquito bites than the cats in the control group. The same effect was true for the scientists who’d volunteered their arms in solidarity with their feline subjects. These mosquito-repelling properties are currently our best explanation for why cats love silvervine and catnip. But researchers still had one more question: in their state of euphoria, cats tend to vigorously bite, lick, and rub against these plants. But do cats really need to go this crazy to get their bug-repelling effects?为验证这一猜想,研究人员搭建了放有蚊子的笼子,猫咪可以把头伸进笼内。结果证实,体表接触过荆芥内酯醇的猫咪,被蚊子叮咬的次数少于对照组。就连主动挽起袖子、甘愿和猫咪一同参与实验的科研人员,手臂上的叮咬次数也同样大幅减少。目前,这种驱蚊特性是我们解释猫咪喜爱木天蓼与猫薄荷最合理的假说。但研究者还有一个疑问:当猫咪在亢奋状态下,往往会使劲啃咬、舔舐并用力蹭擦这类植物。可它们真的需要表现得如此“上头”,才能真正发挥驱虫功效吗?To investigate rubbing, they provided cats with filter papers treated with microscopic amounts of nepetalactol. And sure enough, even these tiny doses made the papers irresistible, suggesting that microscopic amounts of bug repellent can be transferred by rubbing alone. As for biting and licking, the researchers found that when cats damage the plant, the leaves actually produce more mosquito-repellent chemicals. So your cat isn’t just ripping open their bags of catnip to be annoying; their evolutionary instincts are just trying to get even more of that bug protection.为研究摩擦行为,研究人员向猫咪提供了只沾有微量荆芥内酯醇的滤纸。不出所料,即便剂量微乎其微,这些滤纸依旧对猫咪有着极强吸引力。这说明,仅靠蹭一蹭,就能沾上微量的驱虫物质。至于啃咬和舔舐,研究人员发现,当猫咪啃破植物组织时,叶片反而会生成更多驱蚊化学成分。所以,你的猫咪扒开猫薄荷袋子并不是故意捣乱,而是在进化本能驱使下,想要获取更多驱虫保护。Cats are far from the only animal to use natural plants for purposes like this. Apes swallow scratchy and hairy leaves to dislodge parasites from their guts. Sheep munch on tannin-rich plants to kill intestinal worms, and monarch butterflies use toxic milkweed to kill parasites that normally impair their flight. Just like cats’ ability to find mosquito repellent, these behaviors can help humans identify useful plants and ingredients in the natural world. So, the next time you see your feline friend on a catnip binge, don’t worry – it’s only medicinal.并非只有猫咪会利用天然植物达成这类目的。猿类会直接吞下粗糙多毛的叶片,借此刮擦并排出肠道寄生虫;绵羊会食用富含单宁的植物来杀灭肠道蠕虫;帝王蝶则会采食有毒的马利筋,清除会削弱自身飞行能力的体内寄生虫。和猫咪寻找天然驱蚊植物的本能一样,这类动物行为,也能帮助人类发掘自然界里有价值的植物与成分。所以,下次看到你的猫主子沉迷猫薄荷,不必担心——这只是它在“用药”而已。【词汇】1.stoic adj. 坚忍的;沉着的2.whiff n. 一闻;一股气味3.drool v. 流口水4.wriggle v. 扭动;蠕动5.feline adj. 猫科的;猫的6.euphoria n. 欣快;极度愉悦7.catnip n. 猫薄荷8.painstaking adj. 煞费苦心的;极其仔细的9.dribble v. 使滴下;滴落10.pounce v. 猛扑;突然袭击11.endorphin n. 内啡肽12.lynx n. 猞猁13.jaguar n. 美洲豹14.dislodge v. 驱逐;移开15.munch v. 大声咀嚼16.intestinal adj. 肠的17.milkweed n. 马利筋(一种植物)18.binge n. 狂欢;放纵行为 (本文图片来源于摄图网,版权归摄图网所有)

TRANSCRIPTHow do cigarettes affect the body?Cigarettes aren’t good for us. That’s hardly news — we’ve known about the dangers of smoking for decades. But how exactly do cigarettes harm us? Let’s look at what happens as their ingredients make their way through our bodies, and how we benefit physically when we finally give up smoking.With each inhalation, smoke brings its more than 5,000 chemical substances into contact with the body’s tissues. From the start, tar, a black, resinous material, begins to coat the teeth and gums, damaging tooth enamel, and eventually causing decay. Over time, smoke also damages nerve-endings in the nose, causing loss of smell.Inside the airways and lungs, smoke increases the likelihood of infections, as well as chronic diseases like bronchitis and emphysema. It does this by damaging the cilia, tiny hairlike structures whose job it is to keep the airways clean. It then fills the alveoli, tiny air sacs that enable the exchange of oxygen and carbon dioxide between the lungs and blood. A toxic gas called carbon monoxide crosses that membrane into the blood, binding to hemoglobin and displacing the oxygen it would usually have transported around the body. That’s one of the reasons smoking can lead to oxygen deprivation and shortness of breath.bronchitis n. 支气管炎 emphysema n. 肺气肿 alveoli n. 肺泡 sac n. 囊,气囊 membrane n. 膜 hemoglobin n. 血红蛋白 (Q1) Within about 10 seconds, the bloodstream carries a stimulant called nicotine to the brain, triggering the release of dopamine and other neurotransmitters including endorphins that create the pleasurable sensations which make smoking highly addictive. Nicotine and other chemicals from the cigarette simultaneously cause constriction of blood vessels and damage their delicate endothelial lining, restricting blood flow. These vascular effects lead to thickening of blood vessel walls and enhance blood platelet stickiness, increasing the likelihood that clots will form and trigger heart attacks and strokes.dopamine n. 多巴胺 neurotransmitter n. 神经递质 endorphin n. 内啡肽 endothelial adj. 内皮的 lining n. 内衬,内膜 Many of the chemicals inside cigarettes can trigger dangerous mutations in the body’s DNA that make cancers form. Additionally, ingredients like arsenic and nickel may disrupt the process of DNA repair, thus compromising the body’s ability to fight many cancers. In fact, about one of every three cancer deaths in the United States is caused by smoking.And it’s not just lung cancer. Smoking can cause cancer in multiple tissues and organs, as well as damaged eyesight and weakened bones. It makes it harder for women to get pregnant. And in men, it can cause erectile dysfunction.dysfunction n. 功能障碍 But for those who quit smoking, there’s a huge positive upside with almost immediate and long-lasting physical benefits.Just 20 minutes after a smoker’s final cigarette, their heart rate and blood pressure begin to return to normal. (Q2) After 12 hours, carbon monoxide levels stabilize, increasing the blood’s oxygen-carrying capacity. A day after ceasing, heart attack risk begins to decrease as blood pressure and heart rates normalize. After two days, the nerve endings responsible for smell and taste start to recover.Lungs become healthier after about one month, with less coughing and shortness of breath. (Q3) The delicate hair-like cilia in the airways and lungs start recovering within weeks, and are restored after 9 months, improving resistance to infection.cilia n. 纤毛 By the one-year anniversary of quitting, heart disease risk plummets to half as blood vessel function improves. Five years in, the chance of a clot forming dramatically declines, and the risk of stroke continues to reduce. (Q4) After ten years, the chances of developing fatal lung cancer go down by 50%, probably because the body’s ability to repair DNA is once again restored. Fifteen years in, the likelihood of developing coronary heart disease is essentially the same as that of a non-smoker.plummet v. 暴跌,骤降 coronary adj. 冠状的,冠状动脉的 There’s no point pretending this is all easy to achieve. Quitting can lead to anxiety and depression, resulting from nicotine withdrawal. But fortunately, such effects are usually temporary. And quitting is getting easier, thanks to a growing arsenal of tools. Nicotine replacement therapy through gum, skin patches, lozenges, and sprays may help wean smokers off cigarettes. They work by stimulating nicotine receptors in the brain and thus preventing withdrawal symptoms, without the addition of other harmful chemicals. Counselling and support groups, cognitive behavioral therapy, and moderate intensity exercise also help smokers stay cigarette-free.lozenge n. 含片,润喉片 wean v. 使断奶,使戒掉 That’s good news, since quitting puts you and your body on the path back to health.Part III. KEYQ1. C.【解析】细节题。根据“Within about 10 seconds, the bloodstream carries a stimulant called nicotine to the brain, triggering the release of dopamine and other neurotransmitters.”,可知血液将一种叫尼古丁的刺激物输送到大脑,触发多巴胺和其他神经递质的释放,使人吸烟成瘾。正确答案为C。 Q2. B.【解析】细节题。根据“After 12 hours, carbon monoxide levels stabilize, increasing the blood’s oxygen-carrying capacity.”,可知在戒烟后12小时,血液中的一氧化碳水平稳定下来,增加了血液携带氧气的能力,是戒烟后即时身体益处。正确答案为B。 Q3. D.【解析】细节题。根据“The delicate hair-like cilia in the airways and lungs start recovering within weeks, and are restored after 9 months, improving resistance to infection.”,可知呼吸道和肺部的纤毛在几周内开始恢复,并在9个月后恢复,提高了对感染的抵抗力。正确答案为D。 Q4. B.【解析】推理题。根据“After ten years, the chances of developing fatal lung cancer go down by 50%, probably because the body’s ability to repair DNA is once again restored.”,可知在戒烟十年后,患致命肺癌的几率下降了50%,可能是因为身体修复DNA的能力再次恢复。从中可以推断,戒烟后身体会逐渐恢复修复DNA的能力。正确答案为B。 Q5. A.【解析】主旨题。文章主要讨论了吸烟对身体的危害以及戒烟带来的健康益处处。正确答案为A。 (本文图片来源于摄图网,版权归摄图网所有)

Designing products to look like gadgets. D. Reducing the harmful effects of tobacco. Part II. 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)
