C．At the Shelton Hotel. 3．What time is Michael leaving his place tomorrow morning? A．At 7：40. B．At 8：00. C．At 8：20. [听力原文] W：Hello，Michael. M：Hi，Sarah. W：Are you attending the conference tomorrow morning at the Shelton Hotel? M：Yes，are you? W：Yeah，but when I arrived home 5 minutes ago，I found that my car wouldn’t start.And John is in Brighton on business. M：Do you know what’s wrong with the car? W：I’m not exactly sure.I think there’s a problem with the engine. Er，I wonder if you could give me a ride to the hotel tomorrow morning. M：Sure，when shall I be at your place? W：Well，what about 8 o’clock? From my place to Shelton we have to drive through the quarters，so we’d better leave early to avoid the traffic. M：OK，no problem.It takes 20 minutes to reach your place，so I’ll set off at 7：40.By the way，do you also need me to drive you home tomorrow afternoon? W：No.John will be back then and he’ll get me home.Thank you，Michael. M：That’s OK.See you tomorrow. [记笔记] 浏览完题干和选项，听第一遍，先了解对话的大体意思：女士给男士打电话求捎带，因为自己的汽车可能出了问题，而丈夫出差不在家。然后两人约定了时间。在听第二遍时，可以这样记下下列信息： pro (＝problem) → (＝arrived)(表示“家”) ←5 mins (＝5 minutes ago) 20 mins (＝minutes) [听力分析] 女士遇到了麻烦，打电话很可能是求助。所以第1题答案是A。 女士是五分钟之前到家的，所以现在她在家里。所以第2题选B。 女士建议男士8：00去接她；男士到女士家需要20分钟，所以男士需要在7：40从家里出发。所以第3题选A。 Part 3　交际常用语 本单元的交际用语所涉及的中心话题是谈论绿色生活，谈论与绿色生活相关的知识和生活方式，养成保护环境的好习惯。以下是该类话题常用的交际语言： 1．Welcome to our exhibition on green living. 欢迎参加我们的绿色生活展览。 2．You may wonder what we mean by green living. 你可能想知道我们所说的绿色生活是什么意思。 3．And you will see that our actions as humans are the main sources of pollution. 而且你会发现我们人类的行为是污染的主要来源。 4．For example，a good way to reduce pollution is to plant more trees. 例如，减少污染的一个好办法是多植树。 5．To me，green living is about living in harmony with nature. 对我来说，绿色生活就是与自然和谐相处。 6．It is our responsibility to save energy in our daily life. 在日常生活中节约能源是我们的责任。 7．If possible，you’d better go to school by bike or on foot. 如果可能，你最好骑自行车或者步行去上学。 8．Each of us can make a difference to our environment by leading a green life. 通过绿色生活，我们每个人都可以对环境产生影响。 听说能力 强化训练 一、听力仿真训练 听下面5段对话，回答第1至5题。 1．How long will the speakers wait for the bus to leave?

What moved Senator Nelson to action was the 1969 massive oil spill (溢出) in California, which had killed about 3，500 sea birds, besides sea animals like dolphins and seals, causing great public anger. Inspired by the student antiwar movement at that time, Nelson found it a proper time to channel the energy of the students towards a fight for environmental protection. And the sure-fire way was through public pressure. Thus Earth Day was born in 1970, and public environmental awareness took center stage. On 22nd April 1970, millions of Americans took to the streets to demonstrate for a sustainable environment and thousands of students marched against the worsening environment.Different groups were now working together for a shared goal—environmental conservation and the effort became effective.The government took tougher measures and affected businesses were forced to follow standards. As environmental issues were not just localized ones but a global concern, the year 1990 saw Earth Day reach out to many more around the world. Earth Day 1990 helped pave the way for the 1992 United Nations Earth Summit in Rio de Janeiro, bringing together many nations for a joint effort towards protecting the environment. For his role as the founder of Earth Day, Senator Nelson was awarded the Presidential Medal of Freedom (1995), the highest honour in the USA. We salute (致敬) the man, as the fight for cleaner environment continues. [语篇解读]　本文是一篇记叙文。文章主要介绍了Gaylord Nelson创办地球日的原因，及其为提高公众保护环境意识和保护地球所做出的贡献。 1．What motivated Senator Nelson to start Earth Day?

Researchers at the University of Michigan have been exploring the possibilities of AI in understanding what our furry friends are trying to communicate through their barks (吠).Their new AI tool can tell playful barks from aggressive (挑衅的) ones, as well as identifying a dog’s age, sex and so on, based on their sounds. One of the biggest problems in developing AI models for animal sounds is the lack of publicly available data.Unlike human speech, which can be easily recorded, collecting sounds from animals is quite an effort.“Animal sounds are much harder to get and record，” explained Artem Abzaliev, an expert in computer science and engineering.“They must be passively recorded in the wild or, for house pets, with the owner’s permission.” To solve this problem, the researchers adapted an existing model designed for human speech analysis.The AI model, called Wav2Vec2, was originally designed to recognize human speech patterns.This model is excellent at identifying tones, pitch, and accents in human voices, so the researchers made use of it to analyze dog barks.Surprisingly, it could tell different types of barks with up to 70% accuracy (准确度)! It was even better than models specifically designed for dog barks, which researchers found totally interesting. The significance of this research is great.For biologists and animal behaviorists, this technology offers a new tool for studying animal communication. More importantly, for pet owners and vets, understanding the small differences of dog sounds can greatly improve how humans understand and respond to dogs’ emotional and physical needs.This advance could promote animal care and prevent dangerous situations. Hopefully, this research will prepare for even more advanced tools to help us understand our pets better.“There is so much we don’t yet know about the animals that share this world with us.Advances in AI can be used to change our understanding of animal communication，” said Artem. [语篇解读]　本文是一篇说明文，介绍了人工智能(AI)在理解狗的吠声方面的应用，特别是Wav2Vec2模型如何被调整用于分析狗的吠声，并准确区分它们的情感状态，以及这项技术对于生物学家、动物行为学家、宠物主人和兽医的重要意义。 5．What is a challenge of using AI for dog sounds? A．Too many sound types. B．Lack of existing models. C．Weak public awareness. D．Difficulty in data collecting. 答案：D 5 6 7 8 解析：细节理解题。根据第二段中的“One of the biggest problems in developing AI models for animal sounds is the lack of publicly available data.Unlike human speech, which can be easily recorded, collecting sounds from animals is quite an effort.”可知，使用人工智能来收集动物声音的数据比较困难。故选D。 5 6 7 8 6．What can we infer about the Wav2Vec2 model? A．It is specifically designed for dog barks. B．It can only recognize playful barks of dogs. C．It can tell dog sounds better than human voices. D．It is relatively dependable in identifying dog sounds. 答案：D 5 6 7 8 解析：推理判断题。根据第三段中的“Surprisingly, it could tell different types of barks with up to 70% accuracy！”可知，Wav2Vec2模型原本设计用于识别人类语言模式，但研究人员将其调整用于分析狗的吠声，并且准确度高达70%，这表明该模型在识别狗的声音方面相对可靠。故选D。 5 6 7 8 7．Why does the model matter to dogs and humans? A．It can greatly satisfy our sense of wonder. B．It can help us take better care of our furry friends. C．Dogs will no longer fall into dangerous situations. D．Dogs can respond to the emotional needs of humans. 答案：B 5 6 7 8 解析：推理判断题。根据第四段中的“More importantly, for pet owners and vets, understanding the small differences of dog sounds can greatly improve how humans understand and respond to dogs’ emotional and physical needs.This advance could promote animal care and prevent dangerous situations.”可知，这项技术可以帮助宠物主人和兽医更好地理解狗的情感和身体需求，从而改善人类对狗的理解和反应，促进动物护理并预防危险情况，帮助人们更好地照顾毛茸茸的朋友。故选B。 5 6 7 8 8．What can be a suitable title for the text? A．From Barks to Words：AI Identifies Dog Sounds B．From Humans to Dogs：AI Models Develop Fast C．Wav2Vec2：A Model Designed for Human Voices D．AI for Dogs：A Helper to Promote Dogs’ Emotions 答案：A 5 6 7 8 解析：标题归纳题。根据第一段中的“Researchers at the University of Michigan have been exploring the possibilities of AI in understanding what our furry friends are trying to communicate through their barks.”及全文可知，文章介绍了AI如何帮助我们理解狗的吠声，因此标题应该反映出AI技术在识别狗的声音方面的应用，选项A最适合作为本文的标题。故选A。 5 6 7 8 $$
