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

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

And it was our first time that we were faced with this condition called hypertension. (Q1) Today, we are going to talk about hypertension or high blood pressure. How big is the problem? What exactly happens in your body when you have hypertension, and how can you protect yourself? And here to talk to us about it is Doctor Taskeen Khan. Welcome, Taskeen. Talk to us about hypertension. Why is it called the ‘silent killer’?hypertension n. 高血压Taskeen Khan: Thank you, Vismita. Quite excited to talk to you about hypertension. (Q2) And the reason why it’s called a ‘silent killer’ is because it’s completely symptomless. So what you described with your mum walking around, perfectly okay, and then suddenly finding out that you have high blood pressure. And high blood pressure leads to deadly conditions like heart attack, stroke, kidney disease, but is completely symptomless.Vismita Gupta-Smith: So, Taskeen, how big is this problem of hypertension?Taskeen Khan: Actually, it’s very common. It affects one in three adults globally, and yet only one in five people are actually controlled for their blood pressure. (Q3) We’ve actually estimated at the WHO that we can save 76 million lives by 2050 if we can increase control rates globally. That’s about the size of South Africa, Vismita.Vismita Gupta-Smith: So, Taskeen, how did I do?Taskeen Khan: You did very well. This top number is your systolic blood pressure, which is actually when the heart muscle contracts or beats. And this bottom number is your diastolic blood pressure, which is when your heart muscle relaxes.systolic adj. 心脏收缩的diastolic adj. 心脏舒张的Vismita Gupta-Smith: So, explain to us what exactly happens in our body when we have high blood pressure.Taskeen Khan: There are vessels in your body called arteries and these arteries carry oxygenated blood to your organs. (Q4) When hypertension occurs, it thickens these arteries or makes them stiff or has little clots in them. And those clots actually travel to the heart or the brain and cause heart attacks and strokes.artery n. 动脉oxygenate v. 供氧；输氧clot n. 凝块；血块Vismita Gupta-Smith: Taskeen, give us your top tips to manage high blood pressure and also to prevent it.Taskeen Khan: Of course. So the first thing is to start off like your mom did, seeking medical care, going regularly to the doctor if you are diagnosed with hypertension and taking your medication as prescribed. Personally, Vismita, my own grandmother has hypertension, I diagnosed her and I put her on the same medication that the WHO guideline actually has – really good recommendations there. And also, if you think about your lifestyle, I like to think about it in the ‘Four S’s’. So if you’re smoking, please stop smoking. Reduce sodium or salt in your diet. (Q5) Sleep is very important for the blood pressure and of course reduce your stress.sodium n. 钠 Vismita Gupta-Smith: Wow, let’s see if I’ve got the ‘Four S’s’. First one, stop smoking. Take less salt, that’s the second S. Sleep more and pay attention to your sleep quality. I’m trying to do that personally. I’m slowly getting there. And what’s the fourth one?Taskeen Khan: (Q5) Stress less... Stress less.Vismita Gupta-Smith: That’s easier said than done. But that’s all we have today in Science in 5. Until next time then, stay safe, stay healthy and stick with science.Part III. KEYQ1. A. 主旨题。根据开头的“Today, we are going to talk about hypertension or high blood pressure. How big is the problem?

It’s a common theory, but actually, it isn’t really true! The average human brain is full and actively engaged with all of its parts. However, that doesn’t mean it’s unable to do more!By creatively adapting new pathways through skills, knowledge and experiences, you may find hidden potential you never knew existed. But how do you do that?Isn’t Your Brain Already Busy Enough?Well, yes. The brain never stops doing its job in some capacity. (Q2) Even during sleep, the brain is refreshing and processing the information it’s taken in.The human brain has approximately 100 billion neurons. It’s basically the control center of everything we think, do and say. By sending and receiving chemical and electrical signals throughout the body, our brain keeps us alive, and helps us experience our world both inside and out.Science can tell us what parts of the brain are associated with certain thoughts and actions. For example, the cerebrum, brainstem, cerebellum and cerebral cortex all have specific functions. The brain is divided into two “hemispheres” that communicate with each other through an organ called the “corpus callosum.” Many other glands and organs complete our amazing brains and allow us to experience our human existence.cerebrum n. 大脑cerebral adj. 大脑的；智力的cortex n. 大脑皮层callosum n. 胼胝体Yes, it’s complicated, and very, very busy! But that’s the beautiful thing about it. It loves to be busy. And if you don’t give it enough to do, it often starts to ruminate thoughts, just to have something to think about.ruminate v. 沉思；认真思考The “untapped potential” is the ability of your brain for growth and adaptation. New pathways can be created. So, even though your brain is always active, there’s always room for more! The question is: how do you make those new connections?As you search for the path to your unleashed genius, the answer might be hiding in plasticity.What’s Plasticity Got to Do With it?(Q3) Neuroplasticity is the way the brain is able to reorganize pathways and create new connections. “Neuro” refers to neurons and “plasticity” refers to the brain’s ability to change. Functionally, the brain can move some tasks from a damaged part of the brain to an undamaged area. Structurally, it can change physically as a result of things like learning. The brain’s ability to grow and change is one of its most amazing features.To get the best out of your brain, you need to treat it well. You might not have given much thought to it, because the brain just does its job without much exertion on our part. But there are things you can do to keep your brain in the best shape possible.(Q4-1) Exercise is one of the best things you can do to promote a healthy brain. (Q5) At least 2.5 hours of moderately intense cardio is recommended each week for most people. Walking, strength training and yoga are some other activities that can fill in the spaces between heavier workouts. A sedentary lifestyle can diminish your brain’s capacity to perform well. So, remember to get up and get moving for optimal brain health!cardio n. 有氧运动sedentary adj. 坐着的，（惯于）久坐不动的(Q4-2) Get good restful sleep. Turn off your cell phone and other electronics at least an hour before going to sleep. Use calming techniques like meditation or slow breathing to relax your body at bedtime. Having a room that is clear of clutter, lights and outside noise can create an environment conducive to peaceful sleep, along with a regular sleep routine.clutter n. 杂乱; 混乱; 喧嚣Laughter and enjoying social time allows you to relax, which produces chemicals in your brain that induce happiness and relaxation. Minimize or avoid stress as much as possible. Laughter and fun can be good for your brain, but chemicals produced by stress can be harmful. So choose your thoughts and activities carefully.(Q4-3) Eat good healthy food. You know the old saying, “garbage in, garbage out”? Your brain will be affected by what you put into your body. So be mindful of what you consume. You really are what you eat. Do you want to be a juicy peach, or a sugary fat-filled donut?How you treat your brain is key to finding your hidden potential and genius status. Your brain is ready and willing to take you there, but it’s up to you to find the way!Train the BrainSo how do you find your way to the holy grail of hidden potential? Train the brain! Anything that stretches your mind above your familiar routine and makes the brain work at something new is a step in the right direction!grail n. 渴望但永远得不到的东西；努力追求但永远不可能实现的目标（或理想）Boosting your cognitive abilities and mental agility are helpful tools in making new connections. Brain Training exercises are a great starting point.agility n. 敏捷；灵活；机敏Crossword puzzles, jigsaw puzzles, and word games are all great brain builders.Play games. (Q6) Card games, and games that involve other people, are a double win. You get some social time as well!Learn a new language or learn to play an instrument.Take a class. Do you like to cook? Want to know more about a hobby? Build a model, knit, learn a new computer skill. Working your memory is another way to train your brain. The University of St. Augustine for Health Sciences recommends memory techniques that may help.Organize information into an outline and highlight important points.(Q7) Use the chunking method, which involves grouping similar things together.Make associations, like remembering someone’s name with a color or object.Mnemonics are a fun way to remember certain facts or bits of information. For example, to recall the lines in a treble clef, use the phrase, “Every Good Boy Does Fine”. The first letter of each word corresponds to the notes of each line - E-G-B-D-F. Likewise, the spaces between can be remembered by using the word “FACE” (F-A-C-E).treble clef: 高音谱号As you find your way down the path of greater mental agility, you’ll most likely have less brain fog, increased awareness and energy. When you stay on this path, you may find your hidden potential rising!Unlock Your Genius with CreativityThe brain is made for creativity. You might say you don’t have the time or energy to be creative, but when you think about it, you’re creating all the time. (Q8) One great catalyst for creation is boredom. Allowing your mind to become bored can spark creativity.In her book, Big Magic, Author Elizabeth Gilbert wrote, “The Universe buries strange jewels deep within us all, and then stands back to see if we can find them.”Brainstorming is another way to help your thoughts flow. Write down all the things you can think of when looking for something new to do or learn, or when trying to solve a problem. Often, one idea will lead to another. Even if it seems impossible, write it down.When you embrace curiosity and try looking at things with a new perspective, you become open to new ideas.Overcome your Limiting BeliefsBelieving in yourself is important when you’ve put your sights on the next level. There may be times of discouragement, but don’t allow doubt to cloud your vision. You are most likely closer to success than you think!Reframe negative thoughts by changing the way you look at challenges. If your brain is telling you something is too hard, you can reframe that thought by telling yourself that it may be difficult, but you can do it.When you continue to take action, step by step, you gain confidence and competence. Ignore negative self-talk, remember how far you’ve come and don’t give up.(Q9) There will be setbacks in any new endeavor, but that’s not the time to quit. Learn from mistakes and failure, because these two travel companions lead you to better understanding. A failed attempt is just a signpost that lets you know you took the wrong turn.Athlete Travis Rice said, “We’ll never know our full potential unless we push ourselves to find it.”The hidden potential of your brain is like buried treasure just waiting for you to discover it. When you create new neural pathways through learning, growth and adaptation, you may find yourself becoming more of who you are meant to be.You never know what genius awaits you until you take the first step and try something new. Wake up your brain! And discover the secrets of your hidden potential.Part III. KEYQ1. A. 细节题。根据“Have you heard the notion that humans use only 10% of their brains?” 可知普遍的理论认为我们只使用了大脑的10%。因此答案为A。Q2.

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
