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)

时文选读 | 全球大学对经济增长的贡献减弱

时文选读| 全球大学对经济增长的贡献减弱Universities are failing to boost economic growth四级 适中| 414词 刘立军供稿Part I. PassageIn the past few decades, universities around the world have grown quickly. The number of researchers working in universities has increased a lot. Since 1980, the number of academic papers published every year has become five times higher. Governments have spent a lot of money on universities because they believe that universities help the economy by creating new ideas and inventions for businesses and society.However, even with this growth, productivity has slowed down. In the 1950s and 1960s, worker productivity in rich countries grew by about 4% every year. But in the 10 years before the COVID-19 pandemic, it grew by only 1%. Even though we now have powerful technologies like artificial intelligence (AI), productivity is still not growing much.A new study by some economists suggests that there may be a link between the rise of universities and the slow growth of productivity. In the past, most big scientific discoveries were made by businesses, not universities. In the middle of the 20th century, companies like AT&T and General Electric spent a lot of money on research. These companies sometimes published more scientific papers than top universities. One reason for this was that strict competition laws encouraged companies to develop their own innovations.But in the 1970s and 1980s, competition rules became weaker. As a result, companies stopped investing as much in research and started depending on universities to do the work instead. The study says that moving from company-led research to university-led research has not helped productivity very much. Even though universities produce important studies, these studies are often hard for companies to use. One reason is that many companies no longer have their own research labs, which used to help different experts work together. Also, university researchers often focus more on getting academic success than on solving real-world problems.When universities do try to create useful inventions, the results are not always good. For example, university patents can sometimes stop companies from doing their own research. The study found that company patenting has gone down by about 1.5% each year because of competition from university start-ups. This means that public funding for university research might be hurting private research by companies.In the future, better teamwork between universities and businesses could help increase productivity. Stronger competition laws might also push companies to invest more in their own research again. But if university research does not clearly help the economy, governments may need to rethink how much money they spend on it.【Vocabulary】1. productivity n. 生产率；工作效率2. publish v. 发表；出版3. invention n. 发明；创造物4. patent n. 专利；专利权5. funding n. 资金；拨款Part II. QuestionsQ1. According to the passage, what was a reason for the decline in corporate research efforts in the 1970s?A. Universities had taken over the role of corporate research. B. Anti-monopoly laws had been strictly enforced. C. Competition policies had been relaxed. D. Corporate labs have been closed.Q2. What is a challenge universities face when engaging in real-world innovation according to the passage?A. Their research often focuses on academic recognition. B. Their patents are not recognized by businesses. C. Their research labs are not well-equipped. D. Their ideas are too difficult for businesses to apply.Q3. What is one problem caused by university patents, according to the passage?A. They help companies create more patents.B. They reduce the number of students in universities.C. They increase public interest in science.D. They make it harder for companies to do their own research. Q4. What can be inferred about the future of university research from the passage?A. It will continue to drive economic growth. B. It may face increased scrutiny from governments. C. It will replace corporate research entirely. D. It will lead to stronger collaboration with businesses.Q5. What is the main idea of the passage?A. Universities have failed to drive economic growth despite their expansion. B. Corporate research labs were more effective than universities in driving innovation. C. Governments should invest more in university research to boost productivity. D. Collaboration between universities and businesses is the key to future innovation.Part III. KEYQ1.【答案】C【解析】细节题。题目出处为“But in the 1970s and 1980s, competition rules became weaker. As a result, companies stopped investing as much in research and started depending on universities to do the work instead.” 意为：“然而，随着20世纪70年代和80年代竞争政策的放松，企业减少了研究工作，转而依靠大学来进行研究。” 因此，正确答案为C。Q2.【答案】A【解析】细节题。题目出处为“Also, university researchers often focus more on getting academic success than on solving real-world problems.” 意为：“此外，大学研究往往优先考虑学术认可而非实际应用。” 因此，正确答案为A。Q3.【答案】D 【解析】细节题。题目出处为“The study found that company patenting has gone down by about 1.5% each year because of competition from university start-ups.” 意为：“研究发现，由于大学初创企业的竞争，公司的专利申请量每年减少了约1.5%。” 因此，正确答案为D。Q4. 【答案】B 【解析】推理题。题目出处为“But if university research does not clearly help the economy, governments may need to rethink how much money they spend on it.” 意为：“然而，如果大学科研的经济效益仍然不明朗，政府可能需要重新考虑给予大学的财政支持。” 因此，可以推断大学研究未来可能会受到政府更严格的审查。正确答案为B。Q5. 【答案】A 【解析】主旨题。文章整体讨论了尽管大学在全球范围内经历了快速扩张，但生产力增长却放缓，大学研究未能有效推动经济增长。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)

What should the public do to protect themselves during an outbreak according to Dr. Wenqing Zhang?A. Avoid going to crowded places.B. Take antiviral medication daily.C. Minimize contact with animals in affected areas.D. Get vaccinated immediately.Part II. TRANSCRIPTAvian InfluenzaVismita Gupta-Smith: We’ve been hearing about avian influenza or bird flu. (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?

Ways to maintain and improve brain health and unlock hidden potential.B. The human brain uses only a small fraction of its capacity.C. The impact of stress on brain function.D. The structure of the human brain.Part II. TRANSCRIPTHow to Tap into the Hidden Potential of Your Brain(Q1) Have you heard the notion that humans use only 10% of their brains? 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二等奖贺静授课

授课点评：贺静老师授课效果较好，教学目标清楚、教学方法得当、教学程序井井有条。此外，贺静老师口齿清晰，语音语调比较纯正、流利；教态端庄自然，有亲和力，教学过程中与学生互动良好，体现了以学生为主体，教师为主导的教学原则。授课分两部分。第一部分介绍该单元（Empire of Wealth）的总教学安排，用了3分30秒，时间把握得比较好。另外，设计的PPT形式多样，各种图表清楚展现了教学安排。授课开始的第三分钟，PPT显示的该单元总教学目标及三篇课文的教学目标一览无遗，加上贺静老师的阐释，清晰地传递了教学目标和学习目标，这能帮助学生在课堂内外围绕主题有效学习。紧接着，贺静老师借助PPT上的流程图比较详细地介绍了授课课文In Praise of Competitive Urges的教学安排，其中的Problem-centred教学方法对学生发现、分析和解决问题有很大帮助。之后进入第二部分：比赛授课阶段。第二部分具体授课含四个阶段。进入第一阶段Warm-up时，贺静老师显得有点紧张，但很快就调整好了状态。该阶段有教师对课文理解的提问，请学生从课文中找到相关的依据回答问题，这种做法本来值得称道，因为授课不能离开课文。但是，Warm-up阶段是课前准备阶段，因此，贺静老师在Warm-up阶段讲解课文不妥，建议把重点放在教材中的Warm-up Activities上，适当设计一些附加的活动，才符合教学逻辑。此外，在总时间为20分钟且第一阶段用了3分30秒的情况下，Warm-up阶段用了5分1秒显得有点过长。之后是第二阶段Questionnaire Results，贺静老师分析解释了调查表中的信息，谈了自己对问题的看法，期间激励学生思考、回答问题，这对培养学生的独立思考能力及理解课文非常有益。Questionnaire之后进入授课第三阶段：Wealth-flaunting Motivations / Summarizing。炫富动机是课文包含的核心内容之一。因此，讨论炫富动机有助于学生理解课文。教师要求学生从PPT上（视频13'）显示的课文段落寻找答案，并要求学生做pair work找到有关的词汇。另外，通过分析课文的修辞寓意，贺静老师阐释了文章作者的真实目的。这一点做得很好。另一方面，根据该单元内容，所授的是“综合商务英语”课程。因此，贺静老师应更多围绕语言难点、篇章结构、写作风格、文法修辞等方面进行解释，让学生对课文有更深层次的理解。第四阶段Assignment在视频18'15"开始。课后作业包括questionnaire设计、调研报告写作、相关阅读作业。这样较好兼顾了综合商务英语课程语言学习和商务实践的教学特点。建议更多以教材内容教学为主，重视语言、篇章教学，在帮助学生充分理解课文的前提下掌握一些商务知识和技能；需要结合课文融入更多的思政教育内容。点评专家：翁凤翔

第12届教学大赛英语专业组二等奖赵雪宇授课

授课点评：赵雪宇老师展示了“3A设计”，整合了准备、习得与应用这三个不同的教学阶段。对教学阶段和教学过程的表述比较清晰，教学过程在“3A设计”的基础上展开，强调学生参与的多元形式，例如学生提问、学生评价、学生总结等。设计框架层次清晰。教学展示与教学设计紧密地融合在了一起。展示伊始，教师提醒学生回忆“3A设计”，并且多次使用“I want you to be/do…”的句式，运用丰富的肢体语言、重读、停顿等方式明确提出了自己的期待，帮助学生更加直观地获得课堂学习的方向感。此外，教师对学生的分享做出了真诚的回应，而不只是用简短的评价话语敷衍了事，这对学习共同体的建构大有助益。这同时体现出教师对英语有着较好的掌握程度，能够从容、准确地重述学生观点，帮助学生修正语言表述上的错误，并提供更加规范、高效的表达方式。整体而言，赵老师在教学展示过程中教态得体，状态自然、松弛，说课清晰，且能够脱离讲稿等材料的辅助完成授课。课堂教学紧密围绕教学目标，环环相扣，逐步深入。她有效运用了多媒体课件，运用多样的视图突出核心教学内容，起到了辅助作用。可以看出赵老师的整体状态（尤其体现为笑容、身势，对重读、停顿的运用，以及真诚的回应）有效吸引了学生的注意力，激发了学生的学习兴趣，为学生创设了安全的发言空间，让学生有分享欲，愿意主动参与课堂互动。最后，建议赵老师未来可以在分析课文内容的同时，进一步在词汇层面对近义词加以辨析。点评专家：杨延宁
