TRANSCRIPTWill AI Mean Death of Music or More Creativity?Inside a recording room at Queen Mary University of London, several researchers are working with new artificial intelligence (AI) tools. (Q1) Their aim is to develop what they call the “new virtual worlds” of music. intelligence n. 智力；才智；智慧Andrea Martonelli and Max Graf are among more than 30 doctoral students working with Mathieu Barthet, a senior lecturer in Digital Media. They are exploring the possibilities of computational creativity and generative AI. Generative AI is a term that describes technology tools designed to operate at human levels. Together, the researchers have set up a futuristic studio where music meets cutting-edge technology. doctoral adj. 博士的；博士学位的Graf showed off a virtual instrument to reporters with the Reuters news agency. Graf calls the instrument Netz. (Q2) Netz is played through an augmented-reality headset. Augmented-reality equipment combines the real world with computer-created content. The device Graf uses follows body movements to create musical sounds like notes and chords. (Q3) Martonelli played a HITar, a guitar with AI sensors added to it. The sensors can read his movements to create percussive, or drum-like sounds. These sounds cannot be made with a normal guitar.chord n. 和弦；和音sensor n. 传感器percussive adj. 打击声的；打击乐器声的AI can be found in music-making, dating back to the 1950s. But recent progress in generative AI has led to divided opinions on the technology. Generative AI grew in popularity last year thanks to the ChatGPT language system. Generative AI can create new sounds, words for music or entire songs on its own. But artists usually use simpler AI to add to their sound. British musician Yungblud said he believes AI can help his music go “to another direction.” Other musicians worry that the technology could go too far. (Q4) Amy Love plays in the English rock group Nova Twins. She said she is not in favor of music that includes artificially generated voices of actual artists. She said she feels the same way about using dead artists’ voices in songs. In November, the Beatles released the song “Now and Then.” It is considered the group’s last song and includes the voice of Beatles musician John Lennon, who died in 1980. Lennon’s voice sounds were taken from an old recording and re-created with AI. (Q5) New York City-based entertainment company Warner Music said in November it was partnering with the estate of the late French singer Edith Piaf to re-create her voice using AI.Many experts say AI raises legal and ethical concerns. But guidelines on generative AI are still only in their early stage. (Q6) Barthet said, “I think AI can have its place in the music production chain.” But he added that is only possible if the technology is guided in the right way and if there are rules in place to make sure that musicians keep some amount of control. ethical adj. （有关）道德的；伦理的I’m Jill Robbins.Part III. KEYQ1. C.主旨题。文章中提到：“Their aim is to develop what they call the ‘new virtual worlds’ of music.”意为：“他们的目标是使用人工智能工具开发他们所说的音乐的‘虚拟新世界’。”因此答案为C。 Q2. B.细节题。文章中提到：“Netz is played through an augmented-reality headset.”意为：“Netz通过增强现实头戴式设备来演奏。”根据此句，可以确定名为Netz的乐器使用的是增强现实技术。因此答案为B。Q3. D.细节题。文章中提到：“Martonelli played a HITar, a guitar with AI sensors added to it. The sensors can read his movements to create percussive, or drum-like sounds.”意为：“马托内利演奏带有人工智能传感器的HITar，这些传感器可以读取他的动作，从而制造打击乐或鼓声。”根据此句，可以确定HITar通过内置的AI传感器读取动作来产生声音。因此答案为D。Q4. A.细节题。文章中提到：“Amy Love plays in the English rock group Nova Twins. She said she is not in favor of music that includes artificially generated voices of actual artists.”意为：“艾米·洛夫是英国摇滚乐队诺Nova Twins中的一员。她说她不赞成在音乐中加入对艺术家的真实演唱进行人工合成后获得的声音。”根据此句，可以确定艾米·洛夫对AI在音乐中潜在的过度使用问题表示了担忧。因此答案为A。Q5. C.推理题。文章中提到：“Warner Music said in November it was partnering with the estate of the late French singer Edith Piaf to re-create her voice using AI.”意为：“华纳音乐公司在11月份表示，它正在与已故法国歌手Edith Piaf的遗产管理处合作，使用人工智能重新创造她的声音。”因此答案为C。Q6. B.细节题。文章中提到：“Barthet said, ‘I think AI can have its place in the music production chain.’ But he added that is only possible if the technology is guided in the right way and if there are rules in place to make sure that musicians keep some amount of control.”意为：“巴特说：‘我认为AI可以在音乐生产链中占有一席之地。’但他补充说，只有当技术得到正确引导并且有规章确保音乐人能对AI的参与保持一定程度的控制时，这才有可能发生。”根据此句，可以确定巴特提到AI在音乐生产链中的地位与需要适当指导和规章有关。因此答案为B。（本文图片来自摄图网，版权归摄图网所有。）

教学素材| 探索人格奥秘：你是J人还是P人？ 近期，网络上关于“J人与P人出行趣事”、“P人如何让J人头疼”、“I人记录生活的‘偷感’瞬间”等话题引发热议。这些词汇究竟有何深意？今天，我们就来揭开这层神秘面纱，一同探寻J人、P人、i人与e人的真面目。首先，我们要揭秘的是J人与P人。这两类人其实挺好区分，他们具有迥异的生活风格，我们在此无需用文字赘述，直接上图，大家来细品品~•做旅行计划时： •啃玉米时： •挤牙膏时 •整理手机桌面时： 由此，想必大家对J人和P人的人格特征已有了基本的判断。我们不难看出，J人在处理外部信息和事件时，倾向于做出决定、制定计划、建立秩序和寻求结论。所以他们是具有判断型（Judging）人格的人。而J即为Judging的首字母，它的动词原型judge就有“审判、判断”的意思。例：It will take a few more years to judge the impact of these ideas.还需要再过几年才能判断这些思想的影响。而P人在面对外界时，倾向于保持开放、灵活，推迟决策，享受过程，他们是具有感知型（Perceiving）人格的一类人。而这个词的动词原型perceive就有“感知，察觉”的意思。例：That morning, he perceived a change in Franca’s mood.那天早上，他注意到弗兰卡情绪的变化。这类Judging和Perceiving这类人格特征的归纳从何而来呢？你猜对了！它们来源于“MBTI”这个东东~MBTI的英文名全称是Myers–Briggs Type Indicator（迈尔斯-布里格斯类型指标）。它是由美国作家伊莎贝尔·布里格斯·迈尔斯和她的母亲凯瑟琳·库克·布里格斯共同制定的一种人格类型理论模型，基于瑞士心理学家卡尔·荣格的心理类型理论。MBTI是全球最常用的性格测试之一，每年有超过200万人完成问卷调查。MBTI将人格划分为四个维度，每个维度包含两个对立偏好，以字母表示：驱动力方式：E（Extroversion） vs I（Introversion）外倾型vs 内倾型关注点在于外部世界还是内心世界。外向者（Extroverts）能量来源于人际交往，内向者（Introverts）则从独自思考与宁静中汲取力量。接收信息的方式：S（Sensing） vs N（Intuition）实感型vs 直觉型在获取信息时，实感型的人更倾向于关注具体细节，而直觉型的人更关注抽象概念。intuition n. 直觉例：I had an intuition that something awful was about to happen.我直觉感到要出乱子了。决策的方式：T（Thinking） vs F（Feeling）思考型vs 情感型思考型的人做决策时更看重逻辑分析，情感型的人则看重个人价值观和情感因素。对待不确定性的态度：J（Judging） vs P（Perceiving）判断型vs 感知型处理外部世界的方式，判断型的人倾向于预先规划和组织，感知型的人则倾向灵活与接纳。回到之前流行的“I人”与“E人”说法，大家应该能找到它们对应的意思了吧！没错，它们实际上就是MBTI中的内向（I）型人格与外向（E）型人格。现在，大家是否已经对J人、P人、I人、E人有了清晰的认识？不妨比对一下，看看自己在日常生活与工作中更倾向于是严谨有序的J人，还是随性自由的P人？在社交场合，更像享受独处的I人，还是热衷交流的E人？其实，每个人都是独一无二的存在。这些人格特征能帮助我们更好地了解自己，但不应该成为我们给自己或是他人贴上的固化标签。随着时间的推移以及环境或是情绪的变化，我们的MBTI人格都是由可能发生变化的哦！*本文图片来源于网络，仅供学习交流使用，侵删。

AI search tools are becoming obsolete due to technological advancements.B. AI search tools are improving the search experience but also pose potential risks.C. AI search tools have completely replaced traditional search engines.D. AI search tools are only available to users who pay for premium services.Part II. TRANSCRIPTHow to Use AI Tools to Improve Quality of Internet SearchesInternet search companies have already built artificial intelligence (AI) tools into their systems. (Q1) And the use of AI systems to support Internet searches is expected to grow sharply in coming years.Some technology experts feel this change can greatly improve the overall search experience for users. But experts also have concerns.One early user, or adopter, of AI search is Google. The American-based company’s search engine currently processes an estimated 80 percent of the world’s Internet search requests.(Q2) Microsoft’s search engine Bing also includes AI-powered results. Bing’s AI system is linked to the company’s Copilot service. Copilot is an AI tool designed to operate across a series of Microsoft business products.Copilot is based on OpenAI’s ChatGPT, which launched in late 2022. ChatGPT is a computer-powered AI tool designed to interact smoothly with humans.Such AI tools — known as “chatbots” or “generative AI” — are trained on massive amounts of Internet data. They have shown an ability to perform human-level writing and create high-quality images and videos based on short, written descriptions.But these AI systems have also demonstrated possible risks. One risk is the tools can present false or misleading information as truth. They can also produce results that represent long-standing biases against minorities or underrepresented communities.Here, we offer some guidance for users seeking new systems to provide improved and relevant search results.l Where do I find AI search tools?Some major search companies have made it easy to find AI search engines on their main search pages.Google’s search system is powered by its own chatbot tool, called Gemini. It can easily be found directly on desktop or mobile phone browsers. Gemini can be used to perform other chatbot actions as well as providing search assistance.(Q3) Google also has been testing a new search offering, called “Search Generative Experience.” It replaces links with AI-produced briefs containing basic facts about a subject. This system is currently limited to U.S. users who sign up through Google’s experimental Labs site.To use AI with Microsoft’s Bing search engine, simply click the Chat or Copilot button underneath the main search window. This should pull up an information box where users can enter their search requests.New AI search sites have also launched. But they are not as easy to find. The Associated Press reports one way to find them is to perform searches for tools on Copilot or Gemini. Some to look out for include Perplexity, HuggingChat, You.com, Komo, Andi, Phind, Exa and AskAI.l Do I have to sign up for or pay for these services?Most of these services have free versions. But generally, there are limits on how many searches a user can make. Users can also upgrade from basic services to higher levels providing smarter AI tools and more search possibilities.Gemini users, for example, can pay $20 for an upgraded version that offers its “most capable” model, called Ultra 1.0.Most of the startup sites are largely free to use and don’t require setting up an account. Many also have upgrade possibilities.l What are the results like? Unlike a traditional Google search, results from AI tools usually produce a longer, readable collection of information. Sometimes, the original source of information is also included. And in some cases, messages are included to warn users about possible misinformation appearing in the results. It is a good idea to try out different AI tools. Results from each can differ, sometimes wildly. (Q4) The AP reports that results from AI-assisted search tools can be especially useful when searching for more obscure facts or information.obscure adj. 费解的；难以理解的I’m Bryan Lynn.Part III. KEYQ1. B.细节题。根据文本中的描述：“And the use of AI systems to support Internet searches is expected to grow sharply in coming years.” 可知，使用AI系统支持互联网搜索的趋势预计将在未来几年内急剧增长。因此答案为B。 Q2. D.细节题。文本提到：“Microsoft’s search engine Bing also includes AI-powered results. Bing’s AI system is linked to the company’s Copilot service.” 这说明与微软的搜索引擎Bing相关联的AI工具是Copilot。因此答案为D。 Q3. A.细节题。根据文本中的信息：“Google also has been testing a new search offering, called ‘Search Generative Experience.’ It replaces links with AI-produced briefs containing basic facts about a subject.” 可知，Google的Search Generative Experience主要是用AI生成的关于某一主题的基本事实概要来替代链接。因此答案为A。 Q4. C.推理题。文本中提到：“The AP reports that results from AI-assisted search tools can be especially useful when searching for more obscure facts or information.” 这说明AI辅助搜索工具在寻找更模糊的事实或信息时特别有用。因此答案为C。 Q5. B.主旨题。文章整体讨论了AI搜索工具如何改善用户的搜索体验，同时也提到了这些工具可能带来的风险，如提供虚假或误导性信息，以及可能反映长期存在的偏见。因此，文章的主要观点是AI搜索工具在提升搜索体验的同时也存在潜在风险。答案为B。（本文图片来源于摄图网，版权归摄图网所有）

TRANSCRIPT The Science of Laughter (1) Isn’t it odd that, when something’s funny, you might show your teeth, change your breathing, become weak and achy in some places, and maybe even cry? In other words, why do we do this bizarre thing that is laughter? bizarre adj. 极其怪诞的；异乎寻常的 (2) (Q1) When you laugh, your abdominal muscles contract rapidly. This alters your breathing patterns, increasing the pressure in your chest cavity, and pushing air out, which might audibly emerge as a snort, wheeze, or vocalization. Because you’re exerting your abdominal muscles much more than you usually would while talking, they may start to hurt. Laughter also inhibits your reflexes and muscle control, causing sensations like leg weakness. chest cavity 胸腔snort n.（尤指表示气愤或被逗乐的）喷鼻息，哼inhibit v. 阻止；阻碍；抑制 (3) So, where does this funny phenomenon come from? Because there’s no archaeological record of laughter, it’s impossible to say exactly how and why it evolved, but scientists have some theories. Importantly, humans are not the only animals today that do something like laughter. Using ultrasonic recorders, researchers in the late 90s realized that rats were basically giggling while being tickled. Scientists have since compiled evidence of at least 65 species - mostly mammals, but also some birds - that vocalize during social play. Some, unsurprisingly, are our closest relatives. compile v. 编写（书、列表、报告等）；编纂 (4) By recording and analyzing the sounds primates make while playing and being tickled, researchers grew more convinced that the ancient ancestor of all great apes did something like laughter. And, because other apes make laughter-like sounds during rough-and-tumble play, (Q2) they think laughter may have originally developed to clearly signal friendly, non-aggressive intent. (5) But of course, humans don’t just laugh when we’re wrestling, but also when we’re amused, and even surprised, confused, or nervous. Some scientists think laughter took on expanded functions after humans split from other great apes and developed large social groups and more complex language abilities. (Q3) They hypothesize that laughter gradually became something we could use not just during play but within speech to convey subtle meanings and a range of contexts to show our emotions. (6) This is thought to be one of the reasons that laughter is contagious: it’s like an invitation to share in someone’s emotional state. Just hearing clips of laughter can activate key regions in your brain, triggering you to smile or laugh yourself. And when participants in one study watched a funny video, they laughed significantly longer and more often when another person was present – even though they reported feeling the same level of amusement. contagious adj.（疾病）接触传染的 (7) Human laughter is also generally louder than the play vocalizations of most animals. Some scientists speculate that this is because our laughter functions not only as a signal between individuals, but a broadcast to everyone around. (8) Studies found that observers across the world and as young as 5 months old could reliably tell the difference between close friends and acquaintances just from brief clips of them laughing. (Q4) Similarly, we can tell whether a laugh is real or fake based just on the sound. Fake, or volitional, laughter is produced in entirely different networks in the brain, relying on speech-like pathways. Meanwhile, spontaneous laughter arises from older networks that other animals also use for their vocalizations. And laughter is not just socially important; it’s also thought to be good for us. When we laugh, our brains release feel-good neurotransmitters like endorphins, and decrease levels of stress hormones like cortisol. (Q5) Some research even suggests that people who laugh more can cope with stress more effectively and have better cardiovascular health. (9) Laughter is a universal human behavior. Babies can laugh before they can speak. Whether it’s the best medicine depends on your ailment. But as something that makes life more tolerable, strengthens bonds, and potentially improves aspects of your health, you can’t go wrong with a good laugh. Unless you have a broken rib or something. Then it’s no laughing matter. Certainly nothing to crack up about. ailment n. 轻病；小恙Part III. KEY Q1. B. 细节题。文章第(2) 段提到：“When you laugh, your abdominal muscles contract rapidly. This alters your breathing patterns...” 意为：“当你笑时，你的腹部肌肉会快速收缩。这改变了你的呼吸模式……”。因此答案为B。 Q2. C. 细节题。文章第(4) 段提到：“...they think laughter may have originally developed to clearly signal friendly, non-aggressive intent.” 意为：“……他们认为笑声最初可能是为了清晰地表达友好、非攻击性的意图而发展起来的。”因此答案为C。 Q3. D. 推理题。文章第(5) 段提到：“They hypothesize that laughter gradually became something we could use not just during play but within speech to convey subtle meanings and a range of contexts to show our emotions.” 意为：“他们假设笑声逐渐成为我们不仅在玩耍中使用，而且在言语中用来传达微妙含义和一系列情境以显示我们的情感的东西。”这说明笑声的功能随着人类从其他大猿类分化后发生了变化，开始承载更广泛的含义和情绪表达。因此答案为D。 Q4. C. 细节题。文章第(8) 段提到：“Similarly, we can tell whether a laugh is real or fake based just on the sound.” 意为：“同样，我们可以只根据声音判断笑声是真是假。” 因此答案为C。 Q5. A. 主旨题。文章第(8) 段提到：“Some research even suggests that people who laugh more can cope with stress more effectively and have better cardiovascular health.” 意为：“一些研究甚至表明，笑得更多的人可以更有效地应对压力，并拥有更好的心血管健康。” 这表明经常笑可能带来的一个结果是改善心血管健康和压力管理。因此答案为A。 （封面图片来自摄图网，版权归摄图网所有）

TRANSCRIPTIt has become easy for students to find and copy published material. But copying another person's writing without giving them credit can get students and other scholars into big trouble. (Q1) Copying another person's writing without crediting them is called plagiarism.plagiarism n. 抄袭；剽窃(Q2) Recently, the leader of Harvard University stepped down over problems related to the use of other peoples' work in her writing.American copyright law protects original works of authorship including books, movies, music, images and artworks. The protection extends to computer software and the design of buildings and structures.The owner can sell a copyright or permit others to use it because it is property and property ownership is protected by law in the U.S.The idea is that copyright helps society. If people can gain from their own creations, called their intellectual property, then more people will want to create original works.(Q3) The law, however, permits the unlicensed use of copyrighted works under what is called fair use. Fair use can include criticism, comment, news reporting, education and research. However, there are some limitations.（Q4）In education, students can include small parts of copyrighted work in their writing and research. But they must provide credit to the original creators through a citation which gives details about the source.Many universities, including Harvard University, even urge students to give credit to sources of ideas when they come from discussions with professors or other students. Harvard even warns students about copying themselves. That is, they cannot hand in the same work for more than one class without the permission of their instructors.A failure to do so is considered plagiarizing.How can professors know if a student is plagiarizing?Just as it is easy to copy, it is also easy for professors to know if a student has plagiarized.First, there are computer programs and artificial intelligence, or AI, tools that compare students' papers to large databases of published writing. The programs can identify whether students have copied published writing. Second, (Q5) if English is not a student's first language, a professor might recognize a change in wording and writing style. This could bring more attention to the student's paper.Plagiarism is punished in different ways. (Q6) Professors could simply warn a student not to do it again, lower their grade, or they might fail the student in that class. In more extreme cases, a student may be temporarily banned or expelled from school.Tools to avoid plagiarismThere are free tools to make citations easier for students and to avoid plagiarism. Zotero is a free, open-source program that helps organize all the research a student may use. For example, it can automatically create citations and combine them into a list. The Purdue Online Writing Lab, or Purdue OWL for short, is another free resource.Many universities also have writing centers where students can learn the citation rules. And another way for students to learn how to avoid plagiarism is to read published papers and pay careful attention to how information is presented. Students should observe when and how citations are used. This can help them learn the rules of citations.In educational, or academic, writing, it is better to cite too much than too little.A possible double standardHarvard's Claudine Gay resigned this month after several accusations of plagiarism in her academic work.Gay's academic writing got attention after she was strongly criticized for her answers to a Congressional committee related to freedom of speech. Critics found several cases of possible plagiarism in her 1997 doctoral paper. Harvard's governing board first supported Gay, saying a review of her scholarly work turned up "a few instances of inadequate citation" but no evidence of research wrongdoing.doctoral adj. 博士（学位）的There has been debate among academics over whether her conduct amounted to academic dishonesty. D. Stephen Voss is an associate professor of political science at the University of Kentucky. He knew Gay when they were graduate students at Harvard. A paper he co-wrote in the 1990s was one Gay is accused of plagiarizing from.(Q7) He said in an interview with the New Yorker magazine that Gay did plagiarize from him.

(Q9) If a problem arises, administrators might think they were just being careless with their citations or use of quotation marks.Students, on the other hand, must follow university policies on academic behavior.

In the whirlwind of daily life, (Q10) it’s easy to overlook the subtle signals whispering that you’re actually more liked than you give yourself credit for.

This attentiveness reflects a profound appreciation for the positive energy and contributions you bring to the group dynamic.attentiveness n. 注意#2 Strangers Feel Comfortable Approaching and Talking to YouIf this is the case, you probably have an innate ability to make people feel acknowledged when you first engage. You likely exude an inviting energy that puts others at ease. (Q2) Something about your demeanor and open body language signals your receptive presence, making people feel comfortable approaching you and initiating conversation. Even a brief exchange of words leaves the other person feeling seen and heard.

Or maybe you’ve noticed that your co-worker consistently reserves a seat for you at those early morning meetings. (Q3) These thoughtful acts are akin to personal gestures of kindness, indicating that people are naturally inclined to extend such niceties to those they truly like. So, if you frequently find yourself on the receiving end of such considerate acts, see it as a quiet endorsement from the universe, affirming that your likability is shining through.nicety n. 细节；细微的差别#4 People Confide in You with Personal Information or SecretsOne telltale sign that you’re more likable than you realize is that people confide in you and trust you with personal information or secrets.

When friends are going through tough times, they know they can turn to you for a listening ear without fear of criticism. Your open and accepting nature creates a welcoming atmosphere and encourages them to be vulnerable and honest with their feelings. Even casual acquaintances sense your compassion and find it easy to talk to you about deeper issues.#5 You Frequently Receive Compliments and Positive FeedbackCompliments signify that you’ve made a positive impression on someone. When people take the time to express their appreciation, it reinforces your appeal and value in their eyes. And, the more you receive kind words, the more evidence there is that you are well-liked by those around you. (Q5) Sincere compliments, especially those referencing your character like “you’re so thoughtful” or “you always know how to cheer me up,” are particularly meaningful. These types of compliments are a direct acknowledgment of your inner qualities.

Even in tense situations, your ability to find humor and share a genuine laugh can cut through awkwardness or discomfort.

Those who turn to you for guidance likely see you as dependable, insightful, and wise beyond your years. Your advice is valued because it comes from a place of thoughtfulness, empathy, and sincere concern.#9 Your Online Presence Reflects PositivityIn a digital world, your online presence can reveal a great deal about how you are perceived. When your interactions consistently reflect positivity, it signals that your placed trust, rapport, and goodwill have earned you respect and likeability within your social circles. It’s not just about the posts you share or the comments you leave; it’s about creating a vibe that resonates with people. When your content and conversations add value by informing, inspiring, entertaining, or helping others, it creates enjoyable exchanges that make you appreciated.rapport n. 亲善；融洽；和谐vibe n. 感应; 气氛resonate with sb. 使产生联想；引起共鸣#10 You Tend to Receive Spontaneous Support(Q9) When others offer to help you out or lend a hand without you even needing to ask, it’s a clear sign that people genuinely care about your well-being. Whether it’s offering to give you a ride when your car is in the shop or bringing over a home-cooked meal when you’re feeling under the weather, these gestures show that others want to support you when you need it most. Such actions speak volumes about how much you are valued by those around you.Reflecting on the signs we’ve covered, it’s likely that you have many qualities that make you pleasant to be around. Even if you don’t notice it yourself, others do respond positively to your warmth, kindness, dependability, and wisdom. These traits not only attract friends and opportunities but also enrich the lives of those around you.Part III. KEY Q1.

授课点评：胡笑然老师以充分的课前准备、认真的育人态度、专业的学科素养、科学的教学方法，在限定的20分钟时间内出色地完成了所指定的授课任务，为全国高校英语专业师生呈现了一堂值得学习和反思的短课。在整个授课过程中，胡老师精神饱满，着装端庄，形象甜美，教态自然，认真专注，热情友好，充满活力，展现了良好的个人魅力，体现了青年教师的时代风貌。胡老师具有扎实的英语基本功、娴熟的课堂掌控能力和应变能力、流畅的语言表达能力；综述简洁明了，呈现单元设计、教学目标、相关活动和拟用时间；授课有明确的目标，以学生为中心，围绕单元主题和语篇意义，突出重点，聚焦难点，讲解和引导规范适切。胡老师有自己的教学理念，能运用一定的教学理论，遵循“题材—功能—活动”的教学原则，重视语言感知和信息获取，围绕单元主题展开教学，各教学步骤衔接自然。能注重培养学生的观察力、想象力和分析能力，积极帮助学生通过语篇学习，了解重要概念以及语篇作者的观念和意图，努力激发学生对语篇主题的学习兴趣，师生之间有积极的互动和良好的交流。能充分利用和发挥电子课件的辅助教学功能， PPT和嵌入视频有良好的功能性和实用性，形式与内容相吻合，体现了课件形式与课文内容、教学手段与教学目的有机关联和主从关系，发挥了现代化教学资源及手段的教学辅助作用，增强了学生对单元主题和语言表述的理解。从整体上看，胡老师的授课比较成功。授课目的明确，授课重点突出，内容讲解清晰，活动安排合理，起承转合自然，师生互动自然，课件使用得当，教学效果较好。当然，她所展示的这堂英语短课仍存在以下待改进之处：授课停留在主题词语的概念解读层面，对主题意义的挖掘不够深入；教师个人主导成分太强，讲解和提问过多，学生活动不足，活动形式比较单一；时间把握不够合理，没有时间结尾，匆忙收课，无法安排课后作业和课外活动；授课时间用于教学，缺乏对教学成效的必要评价活动，难以确定单元教学目标的达成。建议胡老师在今后的教学研究和实践中，更加重视单元设计的完整性和课堂教学的有效性，关注输入与输出、课内与课外、语篇意义与语言形式的协调，注重教学手段、过程、效果的统一，促进学生在语言知识、语用技能、心智、情感、态度等方面的综合发展和提高。点评专家：梅德明

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
