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)

Discovering trends in large datasets.D. Replacing humans in various fields.Part II. TRANSCRIPTImportant Terms and Ideas for Describing Artificial IntelligenceThere are several terms experts use to describe computer systems in the field of artificial intelligence. Recently, the French News Agency (AFP) defined some of the common terms and ideas used in that field. Here is a version for English learners:intelligence n. 智力，智能Artificial intelligence The first term is “artificial intelligence.” When asked what artificial intelligence is, the AI-powered ChatGPT system says that the term means “the simulation of human intelligence in machines that are programmed to think, learn and make decisions”. (Q1) AI’s main quality or characteristic is taking in large amounts of data and then processing it using methods from statistics. AI involves using ideas from many fields including computing, mathematics, languages, psychology, and others. Currently, the technology is being used heavily for investigating health issues, translating human languages, and predicting problems in machine tools and self-driving cars. But AI is affecting many fields of business and industry.simulation n. 模拟，仿真Algorithm A second important term is “algorithm.” (Q2) An algorithm is important to all computer operations. It is a series of steps or instructions followed by a computer program to get a result. Algorithms can give rules for an AI’s behavior, helping it to realize the objectives of computer program developers. Unlike a simple computer program, AI algorithms permit a computer system to “learn” for itself.algorithm n. 算法，运算法则Machine learning A third important term is “machine learning.” Machine learning is one method that researchers have used in their efforts to produce artificial intelligence. Machine learning lets computers learn from data without being directly programmed on what results to produce. In recent years, the field of neural networks has given important results. In a neural network, connections between some nodes are strengthened and others weakened as the system learns and makes changes. Learning can be “supervised.” This means the system learns to put new data into specific groups based on a model. For example, the system could learn to identify spam in an email or other messaging programs. “Unsupervised” learning permits the system to independently discover new areas or ways of doing things. These discoveries in the available data might not have been immediately clear. An example would be letting an online store identify buying trends in sales data. (Q3) “Reinforcement” learning adds a process of repeated trial-and-error. In this process, the system is rewarded based on its outcomes, causing it to learn and improve. One example might be a self-driving vehicle whose objective is to reach its destination as quickly as possible but also safely. That requirement would lead it to learn to stop at red lights although it requires additional time.neural adj. 神经的node n. 节点spam n. 垃圾邮件Deep learning (Q4) Deep learning owes its name to its use of many layers of neural networks. Raw data is examined by each layer in turn at growing levels of abstraction. Geoffrey Hinton received the 2024 Nobel Prize in Physics. Hinton is credited with developing deep learning. Hinton received the prize along with 1980s neural-network developer John Hopfield. Francis Bach, head of France’s SIERRA statistical learning laboratory, said this about deep learning: “The more layers you have, the more complex behavior can become, and the more complex the behavior can be, the easier it is to learn a desired behavior efficiently.” The method might help lead to scientific discoveries.Language models We now turn to large language models (LLMs). These might be the most popular example of generative AI. Large language models’ power tools like OpenAI’s ChatGPT or Google’s Gemini. Such systems are able to write long papers, answer legal questions or even produce a cake recipe based on their statistical models. But the technology is still new. (Q5) LLMs can suffer from “hallucinations” — the creation of content that is false or incorrect.hallucination n. 幻觉，虚构内容Artificial general intelligence A final important term is artificial general intelligence (AGI) — one the big goals of the whole AI field. (Q6) AGI suggests the unrealized dream of a machine able to reproduce all human processes of human thinking. People who push the idea include OpenAI chief Sam Altman and his competitors at Anthropic. They consider such a system to be within reach. The goal is to use large amounts of data and processing power to train LLMs that are increasingly powerful. But critics say that LLM technology has important limits, including its ability to reason. Maxime Amblard, computing professor at France’s University of Lorraine, told AFP last year, “LLMs do not work like human beings.” Amblard added that humans, as flesh-and-blood intelligent beings, are “sense-making machines” with different abilities from today’s computer systems.Part III. KEYQ1. C. 细节题。题目出处：AI’s main quality or characteristic is taking in large amounts of data and then processing it using methods from statistics. 意为：AI的主要特性是接收大量数据并使用统计方法进行处理。因此答案为C。Q2. C. 细节题。题目出处：An algorithm is ... a series of steps or instructions followed by a computer program to get a result. 以及AI algorithms permit a computer system to “learn” for itself.意为：算法是指计算机程序为获得结果而遵循的一系列步骤或指令；人工智能算法允许计算机系统“自主学习”。因此答案为C。Q3. B. 细节题。题目出处：Reinforcement learning adds a process of repeated trial-and-error. In this process, the system is rewarded based on its outcomes, causing it to learn and improve. 意为：强化学习添加了一个反复试验的过程；在这个过程中，系统基于其结果获得奖励，从而学习和改进。因此答案为B。Q4. A. 细节题。题目出处：Deep learning owes its name to its use of many layers of neural networks. Raw data is examined by each layer in turn at growing levels of abstraction. 意为：深度学习因其使用多层神经网络而得名；原始数据依次通过每一层进行更高层次的抽象分析。 因此答案为A。Q5. D. 细节题。题目出处：LLMs can suffer from ‘hallucinations’ — the creation of content that is false or incorrect. 意为：LLM可能会出现‘幻觉’——即生成虚假或错误内容。因此答案为D。Q6. A. 细节题。题目出处：AGI suggests the unrealized dream of a machine able to reproduce all human processes of human thinking. 意为：AGI表达了这样一个尚未实现的梦想——机器能够再现所有人类的思维过程。因此答案为A。 （本文图片来源于摄图网，版权归摄图网所有)

教学素材 | 学会这5招，告别马路杀手，晋升驾驶达人

学会这5招，告别马路杀手，晋升驾驶达人5 Signs You’re a Good Driver词汇：考研 | 句法：考研 | 文本：考研刘立军供稿Driving is a skill that requires not only technical ability but also awareness, patience, and adaptability. Whether you’re navigating busy streets or tackling unexpected challenges, being a good driver involves much more than simply controlling a vehicle. Here are five signs that indicate you’re on the road to becoming a skilled and responsible driver.驾驶不仅需要技术能力，还需要意识、耐心和适应能力。无论是在繁忙的街道上穿行，还是应对突如其来的挑战，成为一个好司机不仅仅是操控车辆这么简单。以下五点，表明你正在成为一位熟练且负责任的司机。1. Defensive Driving防御性驾驶One of the most important strategies for safe driving is defensive driving. This approach doesn’t mean being overly cautious or paranoid but rather making a conscious effort to anticipate potential errors or accidents. For instance, keeping a three-second distance from the car ahead allows you to react in time if traffic stops suddenly. This simple habit can significantly reduce the risk of collisions and is a hallmark of a good driver.安全驾驶最重要的策略之一是防御性驾驶。这种方法并不意味着过分谨慎或草木皆兵，而是要有意识地去预判潜在的错误或事故。例如，与前车保持三秒的安全距离，可以在交通突然停止时为你争取足够的反应时间。这个简单的习惯可以显著降低碰撞的风险，也是优秀司机的标志之一。2. Proper Merging Techniques 正确的并线技巧When faced with a lane closure, many drivers assume they should merge as early as possible. However, studies show that the “zipper merge” — continuing at a steady speed until the lane ends and then merging alternately — is both safer and more efficient. Research suggests that encouraging this method can reduce traffic jams by up to 40%. By following this technique, you not only improve safety but also contribute to smoother traffic flow.面对车道关闭时，很多司机认为应该尽早并线。然而，研究表明，“拉链式并线”——即保持稳定速度行驶直到车道尽头，然后交替并入——既更安全也更高效。研究指出，推广这种方法可以减少多达40%的交通堵塞。通过遵循这一方法，你不仅能提升安全性，还能为交通流畅做出贡献。3. Avoiding Distractions避免分心Distracted driving is one of the leading causes of accidents, yet many drivers underestimate its dangers. While multitasking might seem easy, research indicates that most people struggle to balance driving with other activities. Even hands-free phone conversations can impair reaction times and decision-making as much as driving under the influence. Surprisingly, drivers who believe they are skilled multitaskers often perform worst in tests requiring divided attention. Staying focused on the road is essential for safe driving.分心驾驶是导致事故的主要原因之一，然而许多司机低估了其危险性。尽管同时进行多项任务看似简单，但研究表明大多数人难以在驾驶的同时平衡其他活动。即使是免提电话交谈也会像酒后驾车一样影响反应时间和决策能力。令人惊讶的是，在需要分散注意力的测试中，那些自认为擅长多任务处理的司机往往表现最差。保持对道路的专注对于安全驾驶至关重要。4. Managing Road Rage 管理路怒Road rage is a common issue among drivers, often triggered by stress, impatience, or the perception that others are driving recklessly. Aggressive actions, such as honking or shouting, can escalate dangerous situations. Psychologists suggest that the isolation of being in a car can make drivers feel anonymous, leading to impulsive behavior. Recognizing this tendency and practicing relaxation techniques, such as deep breathing, can help drivers stay calm and avoid unnecessary conflicts on the road.路怒是司机中的常见问题，通常由压力、不耐烦或是认为他人驾驶鲁莽引发。诸如按喇叭或大喊等攻击性行为可能会使危险情况升级。心理学家指出，车内环境的隔离感可能让司机觉得不会暴露自己的身份，从而导致冲动行为。认识到这种倾向并练习深呼吸等放松技巧，可以帮助司机保持冷静，避免在道路上发生不必要的冲突。5. Learning from Mistakes 从错误中学习Even skilled drivers make mistakes, but what sets good drivers apart is their ability to learn from them. Research shows that new drivers who receive feedback on their errors, such as through driving simulators, tend to improve their skills over time. Mistakes, while frustrating, are valuable learning opportunities that help build experience and confidence.即使是“老”司机也会犯错，但是好司机与众不同的地方在于他们能够从错误中学习。研究表明，新手司机如果能通过驾驶模拟器等方式得到关于自身错误的反馈，随着时间推移，他们的技能会有所提高。尽管犯错令人沮丧，但它们是宝贵的学习机会，有助于积累经验，增强信心。 Becoming an expert driver takes time, practice, and a commitment to improvement. Most people learn to drive in their teens or early 20s, a period when the brain is particularly receptive to new experiences and challenges. Starting with short, familiar trips can help build confidence, while gradually tackling diverse driving conditions allows for skill development. 成为一名优秀的“老”司机需要时间、实践以及对自我提升的专注。大多数人会在青少年晚期或二十出头开始学习驾驶，这个时期的大脑特别容易接受新体验和挑战。从短途且熟悉的行程开始，可以帮助新手司机建立信心，而逐渐挑战各种不同的驾驶条件，则有助于技能的发展。Driving is a complex task that requires constant attention to surroundings and adherence to traffic rules. If you practice these habits and stay open to learning, you’re well on your way to becoming a great driver. And who knows? Your ability to parallel park might one day set you apart in a critical situation!驾驶是一项复杂的活动，需要持续关注周围环境并遵守交通规则。如果你养成以上这些习惯，保持开放的学习态度，那么你正朝着成为一名优秀司机的目标稳步前进。谁知道呢？你的侧方停车能力或许有一天会在关键时刻让你脱颖而出！【词汇】1. paranoid adj. 偏执的；多疑的2. hallmark n. 特点；标志3. zipper merge 拉链式并线（一种交替并线的交通方法）4. honk v. 按喇叭；鸣笛5. anonymous adj. 匿名的；无名的6. simulator n. 模拟器7. parallel park 侧方停车；平行停车 （本文图片来源于摄图网，版权归摄图网所有)

TRANSCRIPTHypertensionVismita Gupta-Smith: When my mother was detected with hypertension at the age of 60, it was a huge surprise to us as a family. 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?

TRANSCRIPTLearn about US Presidential CampaignsEvery four years, the United States holds an election for the president in November. This lesson aims to help teachers and learners understand the political processes and expressions used during the election campaign.The political partiesLet us begin with the expression, political party. In elections, parties organize candidates who share party members’ ideas about how government should operate. They try to win elections to gain and keep political power.There are two major political parties in the U.S. They are the Democratic Party and the Republican Party. There are other small political parties at the national level. These include the Libertarian and Green parties.Primaries and caucusesEach of the U.S. states and territories holds votes early in the election year. In many states and territories, these votes are called primaries. You may know the word “primary” as an adjective meaning “happening or coming first” as in “primary school.” When speaking of elections, it is a noun, but it has a similar meaning – it is the first election in a voting process that takes place over one year.You might also hear the term caucus. (Q1-1) A caucus is also a kind of election, but it is held privately by the party and usually does not involve state election officials or equipment. (Q2) The Iowa caucus was for a long time the first presidential contest during an election year.caucus n. 政党骨干会议；（政党的）全体成员，领导班子(Q3) In a primary or a caucus, voters choose the party’s candidates for local and state offices as well as for national offices. The candidates who get the most votes become the candidates for the election in the fall.Primaries can be “open” or “closed.” Anyone can take part in an open primary election – even members of another party. (Q4) Only registered party members can vote in a closed primary.DelegatesIn some states, voters choose delegates in the primaries. State party organizations have different rules for choosing them. Delegates are people who will attend their party’s convention, or general meeting.When a delegate is elected to choose a particular candidate, we say the delegate is pledged to the candidate. To pledge is to promise something.Conventions(Q5) Each party holds a national convention – a large meeting where the delegates officially nominate the candidate that the party supports for the presidential election. The verb “nominate” means to officially choose someone as a candidate for a position. You will hear some other forms of the word in election news.NominationTo describe the process of having the delegates choose a candidate, we use the noun form, “nomination.” At the convention, the candidate who gains the majority of delegates is called the “nominee.” The nominee gives a speech to accept the nomination.The party platform(Q6) The party platform is a statement of the ideology of the party and its candidate. At the party convention, the organizing committee shares its platform. The platform is a statement of the policies that the party hopes to put in place during its candidate’s term in office.ideology n. 意识形态；观念形态The campaign trailPresidential candidates travel the country speaking to voters at a series of events called rallies. Reporters use the expression “campaign trail” to describe these events. This is a metaphor for progressing along a path toward a goal. The election campaign is sometimes called a “race,” another metaphor comparing the election campaign to a sporting competition.metaphor n. 暗喻；隐喻DebatesPart of the campaign process is for the candidates to debate each other. These are televised events where a reporter asks questions that interest the public and gives each candidate a limited time to answer them. The form of the political debates is not the same as traditional academic debates, where teams compete under clear rules and time limits.DonorsPresidential candidates and others who run for public office must find money to pay for those rallies, television advertising, and campaign workers. A common way to pay for a campaign is to ask for money. People who give to a candidate are donors. (Q7) The Federal Election Commission makes rules about how much, when, and how donations can be made.Polls and the PollsResearchers get the opinions of voters in an effort to guess, or predict, the results of an upcoming election. They do this with polls, or public opinion studies. This word has two meanings in the elections. One is where a researcher might ask you about your party affiliation and which candidate you plan to support in a telephone call. Your party affiliation is the party you are registered with or that you support.affiliation n. （与政党、宗教等的）隶属关系(Q8) The other meaning of “poll” is the place where you go to vote on election day. We can also use “polling place.” Schools, religious centers and public buildings can be polling places. (Q1-2) In them, voters cast their ballot secretly. That means they fill out their ballot without pressure from others in the room and turn in their ballot to be counted by poll workers.In the last two election years of 2020 and 2022, people could send in their ballots by mail. (Q9) But polling places remain important for processing and counting ballots.Privacy and politicsNow that you have some of the expressions used to talk about the presidential campaign, you should use them with some care. It is not normal to ask someone what party he or she is a member of although many people will offer that information freely.In some situations, such as among close friends, you will hear Americans talk about the candidates and voice their opinions openly. But when talking with a new acquaintance or a stranger, it is best to avoid asking about political affiliation.(Q10) Also, know that some workplaces have rules against political activity, and, in government, most political activity is not legal although people often share their opinions.Part III. KEYQ1. A. 细节题。根据“A caucus is also a kind of election, but it is held privately by the party and usually does not involve state election officials or equipment.” 和“In them, voters cast their ballot secretly.” 可知党团会议也是一种选举，但它由政党私下举行，通常不涉及州选举官员或设备，也就是说党团会议不采用秘密投票的方式，而一般在投票站，选民秘密地投票。因此答案为A。Q2. B. 细节题。根据“The Iowa caucus was for a long time the first presidential contest during an election year.” 说明爱荷华州党团会议的重要意义在于它是选举年的第一场总统竞选活动。因此答案为B。Q3. C. 细节题。根据“In a primary or a caucus, voters choose the party’s candidates for local and state offices as well as for national offices.” 可知在初选或党团会议中，选民选择该党竞选地方、州以及国家的候选人，也就是选择他们喜欢的候选人。因此答案为C。Q4. D. 细节题。根据“Only registered party members can vote in a closed primary.” 可知只有注册的党员才能在封闭式初选中投票。因此答案为D。Q5. B. 细节题。根据“Each party holds a national convention – a large meeting where the delegates officially nominate the candidate that the party supports for the presidential election.” 可知每个政党都会举行一次全国代表大会——在这个大型会议上，代表们正式提名该党支持的总统候选人。因此答案为B。Q6. B. 主旨题。根据“The party platform is a statement of the ideology of the party and its candidate... the policies that the party hopes to put in place during its candidate’s term in office.” 可知政党纲领是对该党及其候选人意识形态的阐述……该党希望在其候选人的任期内实行的政策，也是就说政党纲领主要目的是概述政党的政策和意识形态。因此答案为B。Q7. C. 细节题。根据“The Federal Election Commission makes rules about how much, when, and how donations can be made.” 可知联邦选举委员会制定竞选有关捐款金额、时间和方式的规定。因此答案为C。Q8. A. 细节题。根据“The other meaning of ‘poll’ is the place where you go to vote on election day. We can also use ‘polling place.’”可知投票地点是指选举日去投票的地方。因此答案为A。Q9. C. 推理题。根据“But polling places remain important for processing and counting ballots.” 也就是说投票地点在处理和计票过程中仍然很重要，可推测出尽管有邮寄投票的方式，但仍有选民可能更喜欢亲自到投票地点投票。因此答案为C。Q10. D. 推理题。根据“Also, know that some workplaces have rules against political activity, and, in government, most political activity is not legal although people often share their opinions.”可知一些工作场所有反对政治活动的规定，并且在政府部门，大多数政治活动是不合法的，尽管人们经常分享他们的意见，可以推测出工作场所的政治讨论通常会受到管制，有时受到限制。因此答案为D。（本文图片来源于摄图网，版权归摄图网所有)

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. C. 细节题。根据“Even during sleep, the brain is refreshing and processing the information it’s taken in.” 可知即使在睡觉时，大脑也会刷新和处理接收到的信息。因此答案为C。Q3. B. 细节题。根据“Neuroplasticity is the way the brain is able to reorganize pathways and create new connections.”可知用来描述大脑重组路径和创建新连接的能力的术语是神经可塑性。因此答案为B。Q4. D. 细节题。根据“Exercise is one of the best things you can do... Get good restful sleep... Eat good healthy food.” 可知锻炼、良好的睡眠和健康饮食对大脑健康有益，而文中也提到要尽量避免压力。因此答案为D。Q5.

第12届教学大赛商务英语组特等奖潘紫萌授课

授课点评：潘紫萌老师在本次大赛中与来自全国各地的商务英语优秀教师展开激烈角逐，在教学理念、教学方法、课堂设计、英语素质、商务知识、教姿教态、师生互动等方面的表现都较突出，最后以总分第一荣获特等奖。潘老师以准确的英语发音先声夺人，丰富的表达方式、适中的语调语速和端庄的教姿教态也令人印象深刻。在课程设计环节，为实现其教学目标，她选择business ethics作为主题，介绍了教学目标、学生特征、以学生为中心和以产出为导向的教学理念，以及线上线下结合、传统和高科技媒体结合等丰富多彩的教学方式。这份介绍全面立体但简明扼要，为后面的演示（demo）课提供了一个很好的支撑。由于大赛的授课时间有限，潘老师突出重点，在演示课上只展示教学方案的第三步，即participatory learning 1 和 post assessment 1。她采用BOPPPS（bridge in, objectives, pre-assessment, participatory learning, post assessment, summary）模型，通过德国大众汽车减排作假、中国支付宝公益植树项目等案例，教学目标涵盖商务英语知识、技能、以及相关的伦理和价值观等。在短短的十几分钟里要达到这么多项教学目标绝非易事。潘老师通过一系列的短视频、多种教学方法（如听力填空、案例讨论、汉译英、样本对话补正等）以及活泼的师生互动，较好地实现了教学目标，显示出选手突出的课堂组织能力。商务英语教学起源于英美等国，因此基本使用本国素材、讲本国故事。传入中国后，主要使用外国素材、讲外国故事。令人欣喜的是，潘老师注意突出中国特色，多次引用中国案例，讲授中国故事，传播中国价值观。加上她出色的英语基本功和良好的师生互动，使得教学过程十分流畅，也没有不同文化同场展示的违和感。总而言之，潘紫萌老师在授课环节的各方面表现都很优秀。不足之处当然也有。首先， 8’13’’开始的讨论过于仓促，只有18秒， 8’31’’就结束了。由于讨论不充分，在随后的问答环节中，更多的回答似乎来自老师而不是学生。第二个是要增加教学过程的自然自发 (spontaneity)。不知是因为课前多次排练还是老师特意要求，学生的产出只有一次对话（17’40’’）相对自然，其他的多次回答虽准确无误，但都像中国小学生朗读课文或回答问题，语音、语调、语速都过于整齐合一，这不利于培养学生的英语实际表达能力。点评专家：陈准民

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
