Lead in Lead in 技术的进步是基于让它融入你的生活，这样你甚至不会真正注意到它，如此一来它就成为日常生活的一部分。 The advance of technology is based on making it fit in so that you don’t really even notice it, so it’s part of everyday life. - Bill Gates What kind of technology is the most important one to you? How do you use it? Lead in I think the most important technology to me is the Internet. I greatly depend on it to get information and communicate with others.Also, devices like computers, smartphones and even some smartwatches now have access to the Internet. These devices allow me to get online from anywhere and at anytime. They are truly a critical part of my daily life. Lead in Twenty Thousand Leagues Under the Sea: travelling deep under the ocean 2001: A Space Odyssey: travelling to _________ The Matrix: connecting the human brain with _________ and entering the virtual world the Moon computers Watch the video and fill in the blanks. Lead in Self-driving vehicles. What other descriptions in science fiction have turned into reality? Mobile phones. Virtual Reality. Artificial Intelligence. … 02. Pre-reading Pre-reading I know that artificial intelligence (AI) is an area of study concerned with making computers collect, analyse and use data to copy intelligent human behaviour. This means that the computers are able to solve problems, understand contexts and adapt in order to respond accordingly in similar future situations. I know that we already use Al in our daily lives, like the voice-activated assistant on some smartphones that helps us find a restaurant or book a taxi. Some cars use AI for navigation and to enhance self-driving capabilities. What do you know about artificial intelligence? Pre-reading Artificial Intelligence: friendly or frightening? How is the author likely to organize the information on artificial intelligence? Title Pictures Pre-reading How is the author likely to organize the information on artificial intelligence? The title uses the words “friendly” and “frightening", which indicates that this article might touch upon the benefits and threats of AI.The four pictures on the next page suggest a possible discussion of the various relationships between AI and human beings－humans and AI may develop a friendly relationship, or AI may pose dangers to humans. Based on all this information, we can infer that the passage might discuss whether humans and AI can live in harmony in the future. 03. While reading While reading Read for structure.

Read for details. Time What happened Since the 1940s Years before the mid-1950s In the mid-1950s In 1997 In 2017 The development of computers has made the dream of AI a reality. The term “artificial intelligence” was coined. A major breakthrough in AI was made. A computer program defeated arguably the best human Go player. Alan Turing had explored the theory of AI.

While reading Read paragraph 4 to 5 and fill in the following table. Read for details. (1) AI is already being applied in many fields. People can use AI to help them drive vehicles,write novels, translate foreign languages and do many other things. From this point of view, AI can be friends with humans. (2) The benefits of Al also bring concerns and fears. Could machines really develop human-like intelligence? And what would happen if they did? Would thinking machines work alongside humans or threaten the existence of humans? How would they be punished if they committed crimes or even murdered humans? As we become more and more dependent on computers, we should think about the dangers posed by the advances in AI. Therefore, the development of AI could also be frightening. AI is already being applied in many fields. People can use AI to help them drive vehicles,write novels, translate foreign languages and do many other things. From this point of view, AI can be friends with humans. While reading Read paragraph 6 to 7 and answer the following question. Read for details. We are getting closer to the dividing line between humans and machines. What are we getting closer to according to the author? 04. Post reading The author is excited but also cautious about AI.He uses the example of having a robot do all your work for you and says “How cool that would be!” He also explains how AI could benefit us by listing various applications of AI, such as health care and machine translation. However, while looking forward to its potential, he is clearly concerned about the possible dangers of AI. He asks a series of questions about the future of AI and quotes Stephen Hawking to show the potential dangers. In the conclusion the author also warns, “We need to make sure that we will not fall victim to AI.” Post reading Critical thinking What is the author’s attitude to artificial intelligence?

In lines 44-46, Stephen Hawking is quoted as saying, “The development of full artificial intelligence could spell the end of the human race.” Do you agree with him? Why or why not? 2. What do you think intelligence machines will be capable of doing in the future?

In lines 44-46, Stephen Hawking is quoted as saying, “The development of full artificial intelligence could spell the end of the human race.” Do you agree with him? why or why not? Option 1 I do not agree with Stephen Hawking. I think that scientists will surely be careful about developing it. Even if we are able to create true artificial intelligence, we will know how to control it. According to the Three Laws of Robotics, robots may not injure human beings or allow them to be harmed, and they must obey the orders.

In the conclusion the author also warns, “We need to make sure that we will not fall victim to AI.” Post reading Discussion Option 2 I agree with Stephen Hawking.With the development of full artificial intelligence, machines may become so intelligent that human beings could no longer control them. If super intelligent AI machines could think and act completely on their own, it remains to be seen how they would treat human beings. It would be extremely dangerous if they decide that humans are their enemies. So I think we need to be very careful with full artificial Intelligence, and it is important that we consider possible dangers before it is too late.

In the conclusion the author also warns, “We need to make sure that we will not fall victim to AI.” Post reading Discussion 2. What do you think intelligence machines will be capable of doing in the future? Intelligent machines will certainly have a lot of influence on our lives in the future. For example, we might all have an AI machine in our homes which can tell us whether we have a medical problem and if we need to go to hospital. It might even take the place of the human doctor and treat us at home or in hospital. I think an AI machine will look after our homes for us: it will be able to tell when we are running low on food or cleaning products, and order them for us based on what we usually get. It might also be able to read our digital calendars and order things like plane tickets and taxis based on where we need to go. 05. Language points Language points 重点单词 1.

I believe that the development of AI has brought significant benefits to us humanity, but we also need to recognize its challenges. As is known to us, AI has already changed the way we live, work and study, allowing us to be more efficient and productive. For example, we can use voice assistants on our smartphones to complete daily tasks. However, the application of AI can also lead to issues such as data privacy and security concerns. Therefore, we should use AI in a reasonable way. This includes strengthening the regulation and control of AI, ensuring its application in the public interest and social progress. Homework AI in Our Lives    As a student fascinated by technology, AI has reshaped my life. One practical example is language-learning apps like Duolingo, which adapt exercises to my weaknesses using AI, making learning efficient. However, risks exist. Over-reliance on AI translators may weaken my skills, while Deepfake videos could spread misinformation, endangering society. To coexist harmoniously with AI, firstly, we must treat it as a tool to enhance, not replace, human capabilities. Additionally, governments and tech firms should collaborate to establish ethical guidelines and stricter regulations. Ultimately, as young learners, we must cultivate critical thinking and never compromise our values for short-term convenience. All in all, AI’s future depends on us. Let’s embrace its benefits while staying cautious. Homework Thank you for your listening Lavf59.27.100 Packed by Bilibili XCoder v2.0.2 null 274848.0 $$
