Today, we are going to continue our exploration of Unit 4 - Digital life. In this digital age, we are surrounded by technology everywhere we go. Smartphones, tablets, laptops, and various digital devices have become an inseparable part of our daily lives. Before we start, I want you to take a moment and think about how you used digital devices yesterday. Maybe you used your phone to text a friend, watched a movie on your tablet, or did some research on the Internet for your homework. Can anyone share one thing they did with a digital device yesterday? Student 1: I used my smartphone to play some games after I finished my homework. Student 2: I watched an English learning video on my computer to improve my English. Teacher: Great! As you can see, digital devices are used in so many different ways in our lives. So, in this unit, we are going to dig deeper into digital life. We will discuss how digital technology has changed our lives, both in positive and negative ways. And we will also learn how to use English to talk about our digital experiences. Are you all ready to start this digital journey with me? Students: Yes! 二、回顾词汇 Teacher: First, let's have a quick review of the new words and expressions we learned in this unit. I will show you some words on the screen, and I want you to read them out loud and tell me their meanings. Here we go. The first word is "digital device". Students: (Read aloud) Digital device. It means any device that uses digital technology, like a computer, smartphone, or tablet. Teacher: Excellent. Next one, "online shopping". Student: Online shopping. It's the activity of buying goods or services over the Internet. Teacher: Correct. Now, "social media". Student: Social media are websites and applications that enable users to create and share content or to participate in social networking, such as Facebook, Instagram, and WeChat. Teacher: Very good. And "cyberbully". Student: Cyberbully means to bully someone using electronic means, like sending mean messages online. Teacher: Well done. Remembering these words is very important as we will use them a lot in our further discussion. Now, let's move on to the next part. 三、探讨数字生活的影响 Teacher: We all know that digital life has brought us a lot of changes. Let's start by discussing the advantages of digital technology. I will divide you into groups of four. Each group needs to discuss and list at least three advantages of digital life. You have five minutes. Start now. (Students start discussing in groups) Teacher: Time's up. Let's hear from each group. Group 1, would you like to share your ideas? Group 1 spokesperson: Digital technology makes communication much easier. We can talk to people from all over the world instantly through video calls and messaging apps. Also, it provides us with a lot of information. We can search for knowledge on the Internet whenever we need. And online learning has become very popular. We can take courses online and learn at our own pace. Teacher: Great points! Group 2, what about you? Group 2 spokesperson: Digital devices make entertainment more accessible. We can watch movies, listen to music, and play games easily. Digital payment is very convenient. We don't need to carry cash around. And it helps businesses grow. They can sell their products online to a wider market. Teacher: Wonderful! Now, let's think about the other side of the coin - the disadvantages of digital life. Again, work in your groups and list at least three disadvantages. You have another five minutes. (Students start discussing in groups) Teacher: Okay, time is over. Group 3, please share your thoughts. Group 3 spokesperson: Spending too much time on digital devices is bad for our health. It can cause eye problems and affect our sleep. There is also a lot of false information on the Internet, and it's hard to tell what's true. And cyberbullying is a big problem. Some people get bullied online. Teacher: Very good. Group 4? Group 4 spokesperson: Digital devices can be a distraction. We may get distracted from our studies or work. There are privacy issues. Our personal information can be leaked online. And people may become addicted to digital devices, which can affect their real-life relationships. Teacher: Excellent job, everyone. As you can see, digital life has both advantages and disadvantages. It's like a double-edged sword. We need to be aware of these and use digital technology wisely. 四、阅读与理解 Teacher: Now, let's turn to our textbooks. We are going to read a passage about digital life. Before you start reading, I want you to look at the title and the pictures and predict what the passage might be about. What do you think? Student 1: I think it might be about how digital technology changes our daily life, because the title is "Digital Life: Transforming Our World". Student 2: Maybe it will talk about different digital devices and how they are used, judging from the pictures of a smartphone, a computer, and a smartwatch. Teacher: Good predictions. Now, start reading the passage quietly. While you read, try to find the main idea of each paragraph and answer the questions below the passage. You have ten minutes. (Students start reading the passage) Teacher: Time's up. Let's go through the passage together. Who can tell me the main idea of the first paragraph? Student: The first paragraph is about how digital technology has become an essential part of our lives, and it gives examples like people using smartphones to check emails and social media first thing in the morning. Teacher: Exactly. What about the second paragraph? Student: It talks about the advantages of digital technology in communication, such as making long-distance communication easier and cheaper. Teacher: Right. And the third paragraph? Student: The third paragraph is about the negative impacts of digital life, like the overuse of digital devices leading to less face-to-face communication. Teacher: Well done. Now, let's look at the questions. For question 1, who can give the answer? Student: The answer is that digital technology has made our lives more convenient, but it also has some negative effects. Teacher: Correct. How about question 2? Student: We should use digital devices in moderation and not let them control our lives. Teacher: Great. Reading comprehension is an important skill. By reading this passage, you not only learned more about digital life but also improved your reading ability. 五、口语练习 Teacher: Now, it's time for some speaking practice. I will give you a topic: "My Digital Life". I want you to talk about your own experiences with digital devices, including what digital devices you use, how often you use them, and what you use them for. You can also talk about the advantages and disadvantages you have experienced. You have three minutes to prepare. Then, I will ask some of you to come to the front and share your stories. (Students start preparing) Teacher: Okay, who would like to be the first one to share? Volunteer, please. Student 1: (Comes to the front) I use my smartphone every day. I use it to call my friends, text my family, and play some simple games. I also use it to study. For example, I have some English learning apps on my phone. The advantage is that it's very convenient. I can learn English anytime and anywhere. But sometimes, I get distracted by the games and spend too much time on them, which is a disadvantage. Teacher: Wonderful sharing! Thank you. Who else wants to share? Student 2: I often use my computer. I use it to do my homework, watch movies, and search for information. It helps me a lot with my studies. I can find a lot of useful materials online. However, sitting in front of the computer for too long makes my eyes tired. Teacher: Great job. Through this speaking practice, you are all getting better at expressing your thoughts in English. Keep it up. 六、语法讲解（动词不定式作宾语补足语） Teacher: In this unit, we also learned an important grammar point - the infinitive used as the object complement. Let's look at some examples. "I ask my friend to help me with my homework." Here, "to help me with my homework" is the object complement. It tells us what the object "my friend" is supposed to do. Another example, "My mother wants me to clean my room." "To clean my room" is the object complement. Can you see the pattern? The verb (like "ask", "want", etc.) is followed by an object, and then the infinitive phrase as the complement. Now, I will give you some sentences, and I want you to identify the object complement. The first sentence is "The teacher tells us to read English every day." Student: "To read English every day" is the object complement. Teacher: Correct. Next one, "He asks his sister to buy some milk." Student: "To buy some milk" is the object complement. Teacher: Well done. Now, I want you to make your own sentences using the infinitive as the object complement. Pair up with your deskmate and share your sentences with each other. You have five minutes. (Students start making sentences and sharing with their deskmates) Teacher: Time's up. Can anyone share a sentence with the whole class? Student: My father asks me to finish my project before dinner. Teacher: Great sentence. Another one? Student: I want my friend to come to my party. Teacher: Excellent. Understanding and using this grammar correctly will make your English more accurate and fluent. 七、写作练习 Teacher: For our last part today, we are going to do some writing. The topic is "The Future of Digital Technology". I want you to think about how digital technology might develop in the future. What new digital devices or applications do you think we might have? How will they change our lives? You can write about three to five paragraphs. First, write an introduction to state the topic. Then, describe some possible future digital technologies in the body paragraphs. Finally, write a conclusion. You have twenty minutes to write. Start now. (Students start writing) Teacher: Time's almost up. Let's stop here. I will ask a few of you to read your writings. Who would like to volunteer? Student 1: (Reads the writing) In the future, digital technology will continue to change our lives. I think there will be more advanced smartphones. They might be able to project a 3D image in front of us, so we can have a more immersive communication experience. Also, smart homes will be more common. All the devices in our homes will be connected, and we can control them with our voice. In conclusion, digital technology in the future will make our lives more convenient and exciting. Teacher: Very creative and well-written! Thank you for sharing. Another volunteer? Student 2: The future of digital technology is full of possibilities. Maybe we will have digital glasses that can show us information wherever we go. We can use them to read books, watch movies, and even get directions. And self-driving cars will become mainstream. They will make our travel safer and more efficient. In short, the future digital technology will bring us a lot of surprises. Teacher: Wonderful job! Through this writing, you not only practiced your writing skills but also let your imagination fly about the future of digital technology. 八、课堂总结 Teacher: Class, today we had a very rich and interesting class about digital life. We reviewed the new words, discussed the advantages and disadvantages of digital life, read a passage, practiced speaking, learned an important grammar point, and did some writing. Digital life is an important topic in our modern society, and learning to talk about it in English is very useful. Remember to keep using English in your daily life to improve your language skills. For homework, I want you to review what we learned today and write a short reflection about what you think is the most important thing you learned in this class.
