教学素材 | 人生旅途轻装上阵

The Art of Traveling Light through Life人生旅途轻装上阵词汇：考研 | 句法：六级 | 文本：考研刘立军 供稿Ancient philosopher Socrates embodied simplicity, owning little and even forgoing shoes. Despite this, he frequented marketplaces not to acquire goods but to appreciate the abundance he could live without, as he famously noted to an inquiring friend. 古代哲学家苏格拉底以其简朴的生活方式著称，他几乎一无所有，甚至常常赤脚行走。然而，正如他曾对一位好奇的朋友所说，他经常光顾市场，不是为了购买商品，而是为了欣赏那些他能够舍弃的丰盛物资。In the context of travel, ‘traveling light’ means moving unencumbered by excessive belongings, which translates into a more pleasant journey with less burden and greater freedom. This idea extends beyond the physical realm into a philosophy for living. This concept encourages us to question what constitutes a life traveled lightly ― is it minimal ownership like Socrates, or is there more to it? 在旅行的语境中，“轻装上阵”意味着不被繁重的行李所累，从而享受更加轻松愉快的旅程，减少负担，获得更多自由。这一理念不仅仅局限于物质层面，它更是一种生活哲学。这种思想引导我们前去思考：什么是轻装上阵的生活——它是像苏格拉底那样过极简的物质生活，还是有更多的内涵？The tale of King Midas reveals that an insatiable desire for possessions can lead to downfall. His wish to turn everything to gold, granted by Dionysus, turns tragic when the things he treasures most are lost to his greed, teaching him the peril of material obsession. 迈达斯国王的故事向我们揭示了一个深刻的道理：对财富的贪得无厌可能导致灭亡。他祈求将一切变为黄金，这一愿望虽由狄俄尼索斯实现了，但当那些他最为珍视的事物因他的贪婪而失去时，这一愿望最终酿成一场悲剧，让他深刻体会到了痴迷物质的危险。Humans naturally accumulate more than necessary, often driven by an innate instinct for survival, from securing homes for shelter to stocking food against hunger. However, for some, this need tilts towards excess, acquiring vast properties and collections of vehicles far beyond necessity, echoing Midas’s folly. While possessions offer convenience, they can also anchor one’s life with responsibilities and maintenance demands, whether it’s the upkeep of a lavish villa or the financial strain of an expensive mortgage, trading freedom for security. 人类出于生存本能，往往会积累超过实际所需的物品，从确保住所的安全，到储备食物以防饥饿，皆出此因。然而，对一些人来说，这种需求逐渐演变为过度的占有欲，他们积累了大量远超必要的财产和车辆，重蹈迈达斯的覆辙。尽管拥有这些财物能带来便利，它们也带来了诸多责任和维护的需求，无论是豪华别墅的日常维护，还是高昂房贷带来的财务压力，都是在以自由换取所谓安全感。Epicurus argued that the pursuit of pleasure should not result in greater distress. Our attachment to both possessions and burdensome thoughts impedes progress. Ancient philosophies, such as Stoicism, Cynicism, and Buddhism, guide us toward letting go of these material and mental weights to alleviate our lives. 伊壁鸠鲁认为，追求快乐不应该导致更多的痛苦。我们对财物的执着以及内心的负担阻碍了我们的进步。斯多葛主义、犬儒主义和佛教等古老哲学都在教导我们：应学会放下这些物质和精神上的重负，让生活变得更加轻松自在。Desires and aversions exert their own weight, where fulfillment leads to contentment and a sense of lightness, while unmet desires breed dissatisfaction and burden. Philosophical traditions across Stoicism, Buddhism, Christianity, and Islam prioritize non-attachment to worldly goods, viewing them as distractions from a path meant for those unburdened. 欲望和厌恶会分别带来不同的负担：当欲望得到满足时，人们会感到轻松和满足；而未满足的欲望则会引发不满和沉重感。无论是斯多葛主义、佛教、基督教还是伊斯兰教，这些哲学传统都强调对世俗财物的淡泊，认为它们是那些追求心灵自由之人路上的障碍，只会分散他们的注意力。The minimalist approach isn’t only about reducing physical possessions but also mental clutter. Letting go of future anxieties and past regrets brings psychological lightness, enhancing our overall well-being and allowing us to navigate life with ease. 极简主义不仅仅意味着减少物质上的财物，它还包含洁净心灵上的杂念。放下对未来的焦虑和对过去的遗憾，可以带来心理上的轻松，进而提升整体幸福感，使我们更加从容地应对生活中的挑战。After periods of global turmoil, embracing a nomadic lifestyle underscored the value of minimalism. The capability to work remotely with minimal equipment exemplifies the physical and metaphysical lightness sought by many. Whether it be in a hotel room or traversing international borders, the ability to live and work with just a suitcase is liberating. 在全球动荡之后，拥抱游牧式的生活方式更加彰显了极简主义的价值。只需极少的装备即可实现远程工作，这体现了许多人所寻求的物质和精神上的双重轻盈。无论是在酒店房间，还是穿梭于国界线之间，仅凭一只手提箱便能自在生活与工作，这一能力赋予人们极大的自由。The agility afforded by traveling light is akin to the experience of playing games like Skyrim with a nimble character. In life, being agile equates to adaptability ― being able to change course rapidly without the encumbrance of possessions or obligations. Ultimately, true lightness is achieved when one’s mind is unburdened by worries and desires, transcending even the most minimalist lifestyle. 轻装上阵所带来的灵活性，就如同在玩《上古卷轴5：天际》游戏时操纵一个敏捷角色的体验。在生活中，灵活意味着适应能力——能够在不被物质所累或义务束缚的情况下迅速改变方向。最终，当一个人的心灵不再受忧虑和欲望所困时，真正的轻盈感就实现了，这种状态甚至超越了最简约的生活方式所带来的自由感。An uncluttered mind allows for a truly light life journey, wherein the absence of mental strain makes even the smallest suitcase seem weightless. 一颗没有杂念的心能让生活旅程真正变得轻盈起来，那时，即便是一个最小的手提箱，在没有精神压力的情况下，也仿佛轻如鸿毛。【词汇】1. forgo v. 放弃2. unencumbered adj. 无负担的；没有阻碍的3. the tale of King Midas 迈达斯的故事。传说，希腊神话中的弗里吉亚王迈达斯贪恋财富，求神赐予点物成金的法术，酒神狄俄尼索斯满足其愿望。最后连他的爱女和食物也都因被他手指点到而变成金子。他无法生活，又向神祈祷，一切才恢复原状。4. insatiable adj. 不知足的；无法满足的5. folly n. 愚蠢；愚笨6. upkeep n. 保养；维修7. villa n. 度假别墅8.

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.

TRANSCRIPTUse Habit Stacking to Help Get HealthyA woman in Portland, Oregon started her daily exercise habit with one activity — walking her dog. Lindsay Kee then added movements to this daily activity. (Q1) Before leaving on the walk, she did some standing stretches. On her return, she did other exercises such as jumping jacks.jumping jacks 开合跳Over time, Kee added more exercises around the dog walk. She said adding exercises to an existing activity took the pressure off of creating a whole new daily exercise. And now more than a year later, she consistently exercises around the dog walk.Kee said, “I’ve found it to be really effective in helping me be consistent with things that I really want to do.”What Kee did is called habit stacking. Writer S.J. Scott created this term for his 2014 book of the same name. (Q2) The idea behind habit stacking is to attach something you want to start doing to something you already do every day.habit stacking 习惯叠加A common example is flossing your teeth after brushing them. However, you can use habit stacking in many areas of your daily life. Kee, for example, places her vitamins next to the coffee machine. This helps her remember to take them every morning.Exercise experts say habit stacking is especially helpful if you are trying to increase exercise time.Dana Santas is a movement expert who has trained more than 50 professional sports teams. She combines exercise habits with personal health care. (Q3) For example, Santas does push-ups before every shower. And she does leg exercises while brushing her teeth. She says that her electric toothbrush makes a sound every 30 seconds to remind her to brush different teeth. But she uses the reminder to change her exercises. “It’s perfect,” she added.push-up n. 俯卧撑Two minutes of exercise may not get you in shape. But experts say, every little bit helps. (Q4) Experts at the U.S. Centers for Disease Control and Prevention suggest getting 150 minutes of moderate activity, like a fast walk, every week. Or you could also get 75 minutes of very energetic activity, like jogging, every week. The health experts also suggest two days a week of strength training.moderate adj. 适度的，中等强度的Most people find keeping new habits difficult. And while habit stacking is not a perfect solution, it does help with one barrier — decision-making.Gretchen Rubin is the writer of Better Than Before: Mastering the Habits of Our Everyday Lives. She said habit stacking is one of the best ways to start and keep new habits. The technique helps to remove the barrier of deciding when or if to do something.Rubin shared a story of her college days. To help her stay active, she would only shower if she had exercised that day.She suggested combining the new, or what she calls “shaky” behavior with something you have to do or deeply want to do.(Q5) “So you have to do the shaky habit before you get to the strong habit,” Rubin said. (Q5) If she wants to listen to a podcast, her strong habit, she must do it while exercising on a running machine. For her, this will strengthen her shaky habit.Part III. KEYQ1. B. 细节题。题目出处为：Before leaving on the walk, she did some standing stretches. 意为：在开始遛狗前，她会做一些站立伸展运动。这表明Kee最初通过在遛狗前做站立伸展运动来培养锻炼的习惯。因此答案是B。Q2. C. 主旨题。题目出处为：The idea behind habit stacking is to attach something you want to start doing to something you already do every day. 意为：习惯叠加背后的理念在于，将你想要开始做的事与你每天已经在做的事联系起来。因此答案是C。Q3. A. 细节题。题目出处为：For example, Santas does push-ups before every shower. 意为：例如，Santas在每次淋浴前做俯卧撑。因此答案是A。Q4. A.细节题。题目出处为：Experts at the U.S. Centers for Disease Control and Prevention suggest getting 150 minutes of moderate activity, like a fast walk, every week. Or you could also get 75 minutes of very energetic activity, like jogging, every week. 意为：美国疾病控制与预防中心的专家建议每周进行150分钟的中等强度活动，如快走；或者每周进行75分钟的高强度活动，如慢跑。因此答案是A。Q5. B. 细节题。题目出处为：If she (Rubin) wants to listen to a podcast, her strong habit, she must do it while exercising on a running machine. 意为：如果她想听播客——这是她常有的习惯，她必须在跑步机上锻炼时听。因此答案是B。（本文图片来源于摄图网，版权归摄图网所有)

What is the primary feature of the car “fob” mentioned in the text?A. It has a long-range communication capability.B. It can unlock the car door as the owner approaches.C. It requires manual activation to send a signal.D. It can only be used within a few feet of the car.Q2. What is a potential vulnerability of the fob that thieves could exploit?A. The fob can be easily damaged.B. The signal from the fob can be cloned by thieves.C. The fob is too expensive for most car owners.D. The fob’s signal can only be sent when the car is unlocked.Q3. What does Steve Launchbury recommend to protect the car key’s signal?A. Storing the key in a Faraday bag.B. Keeping the key in the microwave or freezer.C. Frequently reprogramming the key.D. Using the car's touchscreen to secure the signal.Q4. What is one of the traditional methods to deter car theft that is still considered effective?A. Using a steering wheel lock.B. Hiding the key in the car.C. Painting the car to make it less noticeable.D. Disabling the car’s alarm system.Q5. What is a new theft technique that involves the car’s controller area network (CAN)?A. Jamming the CAN to prevent communication between car parts.B. Physically connecting to the CAN to send unlock or start signals.C. Using a Faraday bag to block the CAN’s signal.D. Cloning the CAN’s signal with a scanner.Part II. TRANSCRIPTHow to Protect Your Car from Being StolenMost recent cars have an electronic key that lets the owner get into and start the car.The electronic key is called a “fob” to those who know about the technology. (Q1) The fob sends a short-range signal to the car. As the owner gets close, the fob unlocks the door.(Q2) But the new technology also makes it easier for criminals to open the car without the key.When you lock your car and take the key with you inside your home, the fob does not stop sending its signal.Thieves, who have special equipment known as scanners, will pass by streets with a lot of cars. (Q2) If the scanner shows that a fob is sending a signal, the thieves use a device that clones the signal and opens the car doors.Government officials around the world have asked carmakers to warn car buyers of the risks of the new technology. They also have asked them to make the fobs more secure.Until then, what can you do to prevent your car from being stolen?Steve Launchbury has some suggestions he shared with the Associated Press. He is the head engineer of automotive security company Thatcham Research based in Britain. Place your key in a protective bag“It’s relatively easy for drivers to protect themselves,” he said.(Q3) The first tip is to put your key into a protective container or bag when you get home. One kind is called a Faraday bag. They are not very costly. The bag is made from a special metal material called mesh that blocks the signal from the fob. Just do not forget to put any extra keys you have into that bag, too.Some advice that is easy to find online says people should put their keys into the microwave or freezer to prevent their signal from being stolen. Launchbury said that does not work and it could harm your key.Get a steering wheel lock(Q4) You may have seen large locks that go across the steering wheel in television advertisements many years ago. It turns out they are still useful. They may be considered “old school,” but the presence of big locks that are easy to see makes car thieves turn away. The only problem is that you must take extra time to unlock the device and put it away before you can drive away.steering n.（车辆等的）转向装置Change the settingsSome car makers permit owners to deactivate the signal sent out by the fob. For Ford, Honda and Audi, owners can use their car’s touchscreen system to find the correct way to turn off the signal. For Toyota, you can turn off the signal by pressing a combination of buttons on the fob.Read your car’s owner’s manual to be sure how to do this.Some car makers include motion sensors on their key fobs. If the fob has not been moved in a while, the fob turns off.If you buy a used car, some experts suggest that you get your keys reprogrammed in case the earlier owner still has a key.New theft techniquesLaunchbury said some cars have a new system called a controller area network, or CAN. The network permits different parts, or components, of the car to communicate with each other. (Q5) He said some thieves are trying to join the CAN through some physical electronic connection to unlock the car. They can do this by removing a headlight and plugging in a device that lets them in the car’s network.The device can send a signal, such as “unlock” or “start” to the central system.Launchbury said this is where the physical lock can cause thieves to change their mind and force them to move on. Owners can also consider electronic immobilizers. These devices prevent a car from moving even if a thief gets into the internal system. However, immobilizers can be costly.Part III. KEYQ1. B. 细节题。根据：“The fob sends a short-range signal to the car. As the owner gets close, the fob unlocks the door.”意为：“fob向汽车发送短距离信号。当车主靠近时，fob会解锁车门。”这表明fob的主要特点是能够在车主靠近时自动解锁车门，答案为B。Q2. B. 细节题。根据：“If the scanner shows that a fob is sending a signal, the thieves use a device that clones the signal and opens the car doors.” 意为：“如果扫描器显示fob正在发送信号，小偷们会使用一种设备克隆信号并打开车门。” 这表明fob的一个潜在漏洞是其信号能被小偷克隆，答案为B。Q3. A. 细节题。根据：“The first tip is to put your key into a protective container or bag when you get home. One kind is called a Faraday bag.” 意为：“第一个建议是，当你回家后，把你的钥匙放入一个保护性的容器或袋子里。其中一种叫做法拉第袋。” 这表明Steve Launchbury推荐将钥匙放在法拉第袋中来保护汽车钥匙的信号，答案为A。Q4. A. 细节题。根据：“You may have seen large locks that go across the steering wheel in television advertisements many years ago. It turns out they are still useful.” 意为：“你可能在多年前的电视广告中看到过横跨方向盘的大型锁。事实证明，它们仍然有用。”这表明使用方向盘锁是一种传统的且仍然有效的阻止汽车被盗的方法，答案为A。Q5. B. 推理题。根据：“He said some thieves are trying to join the CAN through some physical electronic connection to unlock the car. The device can send a signal, such as ‘unlock’ or ‘start’ to the central system.”意为：“他说一些小偷正试图通过某种物理电子连接加入CAN以解锁汽车。该设备可以发送一个信号，例如‘解锁’或‘启动’到中央系统。” 这可以推断出一种新的盗窃技术涉及物理连接到CAN以发送解锁或启动信号，答案为B。（本文图片来源于摄图网，版权归摄图网所有)

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.

TRANSCRIPTUS College Athletes May Soon Get PaidThe National Collegiate Athletic Association (NCAA) and the five biggest college sports conferences recently agreed to pay almost $2.8 billion to settle claims from college athletes.collegiate adj. 大学的；学院的；大学生的(Q1) The NCAA is the organization that runs college sports in the United States. It oversees about 500,000 college athletes from some 1,100 schools.The claims came up over the past 10 years. (Q2) The legal files argued that the NCAA and the conferences prevented college athletes from making money while playing sports for the schools.The greement calls for the NCAA and the conferences to pay $2.77 billion over 10 years to more than 14,000 former and current college athletes.The settlement still needs approval from a U.S. federal judge and different parties to the legal case. (Q3) If it is approved, students who play sports for their colleges will be permitted to be paid, like professional athletes, directly by the schools.Under current NCAA rules, college athletes, also known as student-athletes, can only receive payments from outside groups that use their names, images, and likenesses in commercial efforts, such as advertisements.In a statement, NCAA President Charlie Baker and the school representatives said the agreement was “an important step in the continuing reform of college sports.”Steve Berman, a leading lawyer in the cases, said with the settlement, “college athletes are finally able to receive a fair share of the billions of dollars of revenue that they generate for their schools.”Ramogi Huma, a strong supporter of college athlete’ rights, played football at the University of California, Los Angeles in the 1990s. He called the decision “groundbreaking”, adding that “there’s no going back from there.”More questions remainAlthough the decision provides a reason for celebration for some current and former students, it leaves more questions for others.Earlier in 2024, members of Dartmouth College’s basketball team voted to join a labor organization, called a union. The move means that the student-athletes on the team could have the right to negotiate a working contract like other university employees.Chris Peck is the leader of the union that represents the Dartmouth basketball players. He criticized the decision to settle by calling it “a workaround.”(Q4) Peck noted that the agreement, calling for universities to share money from television deals and ticket sales with athletes, does not answer whether students who play sports are school employees. The union wants a clear answer. Are students who play sports employees? Or, are they more like those who participate in non-study activities like singing in a group?Dartmouth has yet to accept the students’ union vote. And the NCAA is asking the U.S. Congress to step in and say student-athletes are not employees.Tim Walton coaches the women’s softball team at the University of Florida. The school belongs to one of the large conferences that will have to pay millions of dollars into the settlement.softball n. 垒球 (Q5) Walton wants to know what will happen to sports like women’s softball that do not bring in money like men’s football or basketball. He asked: “Are they dropping programs? Are they dropping sports?”In addition, there is a law in the U.S. known as Title IX that requires women and men to have equal rights in education. Does the law require female student-athletes to get paid like men?Michael LeRoy is a sports law professor at the University of Illinois. He said there will be a concern if “women get short-changed.”Christina Stylianou is a sports lawyer in New York. She and LeRoy both said regular payments from universities to students will make it easier for the students to argue that they are indeed employees.LeRoy said the NCAA would like to be able to pay student-athletes but not consider them employees. That, he noted, would mean the NCAA “is going to be treated differently than any other business in America. You cannot have separate pay.”But one college softball player, Tiare Jennings of the University of Oklahoma, did not seem too concerned about the legal questions. She was celebrating the fact that she might have some money saved after college.She said it will be nice for players to know they have money to, in her words, “kick-start your life.”kick-start v. 促使……开始；使（项目）尽快启动I’m Dan Friedell. And I’m Jill Robbins.Part III. KEYQ1. B. 细节题。根据：“The NCAA is the organization that runs college sports in the United States.”可知，NCAA在美国管理大学体育的组织，所以答案是B。Q2. B. 细节题。根据：“The legal files argued that the NCAA and the conferences prevented college athletes from making money while playing sports for the schools.” 意为：“法律文件认为NCAA和会议阻止了大学生运动员在为学校参加体育活动时赚钱。”也就是说运动员没有得到公平的补偿，因此答案是B。Q3. A. 推理题。根据：“...students who play sports for their colleges will be permitted to be paid, like professional athletes, directly by the schools.” 意为：“如果获得批准，为大学参加体育活动的学生将被允许像职业运动员一样直接从学校获得报酬。”可以推断，和解协议意味着如果获得批准，学生运动员可能会被视为学校的雇员，因此答案是A。Q4. B. 细节题。根据：“Peck noted that the agreement...does not answer whether students who play sports are school employees.” 可知，工会主要关心的问题是学生运动员是否被视为雇员，因此答案是B。Q5. D. 推理题。根据：“Walton wants to know what will happen to sports like women’s softball that do not bring in money like men’s football or basketball.” 意为：“Walton想知道像女子垒球这样不像男子足球或篮球那样赚钱的运动会发生什么。”可知，Tim Walton 担心像女子垒球这样不赚钱的运动项目可能会因为学校财务压力而被取消，因此答案是D。（本文图片来源于摄图网，版权归摄图网所有)

第12届教学大赛商务英语组特等奖潘紫萌说课

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

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
