Greetings and Revision T: Good morning, class! How are you today? S: Fine, thank you. And you? T: I'm great. Before we start our new lesson, let's quickly review what we learned in Unit 2. Who can tell me some important inventions we talked about? Yes, David. S: We talked about paper-making, printing, and the Internet. T: Very good, David. These inventions have had a huge impact on our lives. Can you briefly describe how printing changed the world? S: Before printing, books were expensive and few people could learn to read because they were made one at a time by hand. But after the invention of printing, knowledge and ideas spread more quickly. T: Excellent. You remembered the content very well. Now, let's recall some new words and phrases. What does "look through" mean? S: It means to read something quickly to find the information you need. T: Right. And "replace"? S: It means to take the place of someone or something. T: Well done. Now, let's move on to the new content of Unit 3 - Language in use. 2. Grammar Focus - The Passive Voice Review T: In Unit 2, we learned about the passive voice. Let's review it together. Who can tell me the structure of the simple past tense passive voice? S: It's "was/were + past participle". T: Very good. For example, "The book was written by a famous writer." What about the simple present tense passive voice? S: "am/is/are + past participle". T: Correct. Such as "English is spoken all over the world." And the future tense passive voice? S: "will be + past participle". T: Right. Like "A new school will be built next year." Now, let's do some exercises to practice. I'll show you some sentences on the screen, and you need to change them into the passive voice. (Show the sentences on the screen) People plant many trees every year. They will hold a sports meeting next week. We use pens to write. (Students do the exercises and then check the answers) T: Let's check the answers. For the first sentence, who can give the answer? S: Many trees are planted by people every year. T: Good. The second one? S: A sports meeting will be held by them next week. T: Correct. And the last one? S: Pens are used by us to write. T: Well done, everyone. Now, let's look at some special cases of the passive voice. When we want to express the purpose of an action, we can use "be used to do sth" or "be used for doing sth". For example, "Knives are used to cut things." or "Knives are used for cutting things." They have the same meaning. Can you give me some other examples? S: Pencils are used to write. / Pencils are used for writing. T: Great. Now, let's move on to the next part - vocabulary in use. 3. Vocabulary in Use T: Look at the screen. Here are some words and phrases we learned in Module 9. "development", "trade", "amount", "store", etc. Let's see how we can use them in sentences. First, "development". Can you make a sentence with this word? S: The development of technology makes our lives more convenient. T: Very good. Now, "trade". S: Our country has a lot of trade with other countries. T: Right. How about "amount"? S: A large amount of money was spent on this project. T: Excellent. Now, "store". S: We store our clothes in the wardrobe. T: Good. Now, let's do a small game. I'll give you a word or phrase, and you need to make a sentence as quickly as possible. The first word is "look through". S: I like to look through fashion magazines in my free time. T: Great. Next, "at a time". S: You can borrow three books at a time from the library. T: Well done. Now, "by hand". S: My grandmother made this sweater by hand. T: Good job. Through this game, you have a better understanding of how to use these words and phrases. Now, let's move on to reading. 4. Reading Activity T: Now, open your books to the reading part in Unit 3. We are going to read a passage about more great inventions. First, read it quickly and answer this question: What are the main inventions mentioned in the passage? Give you three minutes to read.

Now, read the passage carefully and answer the following questions on the screen. When was the light bulb invented? Who invented the telephone? What are the advantages of the computer according to the passage? Give you five minutes to read and answer. (Students read carefully and answer the questions) T: Let's check the answers. For the first question, when was the light bulb invented? S: The light bulb was invented in 1879 by Thomas Edison. T: Correct. And who invented the telephone? S: Alexander Graham Bell invented the telephone. T: Right. Now, what are the advantages of the computer? S: The computer can store a large amount of information, and it can help people work and study more efficiently. T: Good.

I want you to work in pairs. Each pair chooses one of the inventions we have learned, such as the Internet, the printing press, or the light bulb. Then, one person will act as a reporter, and the other will act as an expert on this invention. The reporter will ask questions about the invention, like "When was it invented?", "What are its advantages?", "How has it changed our lives?" The expert will answer these questions. You have ten minutes to prepare. (Students work in pairs to prepare) T: Time's up. Which pair would like to come to the front and show your dialogue? Pair 1, please. (The two students come to the front and start their dialogue) Reporter: Good morning, expert. I'm a reporter from the school newspaper. I want to ask you some questions about the Internet. When was the Internet invented? Expert: Well, the Internet was developed in the 1960s. Reporter: What are the advantages of the Internet? Expert: The Internet has many advantages. It allows us to get information quickly, communicate with people around the world, and it also provides a lot of entertainment. Reporter: How has it changed our lives? Expert: It has changed our lives a lot. For example, we can study online, do shopping online, and work from home. T: Great job, Pair 1. Your dialogue was very fluent and you used the knowledge we learned very well. Now, let's ask another pair to show their dialogue. Pair 2, please. (Another pair comes to the front and shows their dialogue) T: Very good, Pair 2. After this speaking activity, you should be more familiar with the language related to inventions. Now, let's move on to writing. 6. Writing Activity T: For the writing part, I want you to write a short passage about an invention that you think is the most important in modern life. You need to include the following information: What is the invention? When was it invented? Who invented it (if possible)? What are its advantages? How has it changed our lives? You can use the information and language we learned today and in previous classes. You have 15 minutes to write. Start! (Students start to write) T: Time's up. Let's stop here. Who would like to share your writing with the class? Tom, please. (Tom reads his writing) S: The most important invention in modern life, I think, is the smartphone. It was invented in the late 20th century. Although many companies contributed to its development, Apple's iPhone in 2007 was a milestone. The smartphone has many advantages. It combines the functions of a phone, a camera, a computer, and more. We can use it to communicate with others, take photos, play games, and get information from the Internet. It has changed our lives completely. We can do many things wherever we are. For example, we can order food, book tickets, and even work on our smartphones. T: Very good, Tom. Your writing is well - organized and you used a lot of correct language. Now, let's ask another student to share. Lucy, please. (Lucy reads her writing) T: Excellent, Lucy. Your description is very detailed. After this writing activity, you have improved your writing skills about describing inventions. 7. Summary T: OK, class. Let's summarize what we've learned today. First, we reviewed the passive voice in different tenses and learned some special usages related to it. Then, we practiced using the new words and phrases in sentences and through a game. After that, we read a passage about great inventions and improved our reading skills. We also did a speaking activity and a writing activity to practice using the language to talk about inventions. Can anyone briefly summarize one of the grammar points or activities we did today? Yes, Lily. S: We reviewed the passive voice. The simple past tense passive voice is "was/were + past participle", the simple present tense passive voice is "am/is/are + past participle", and the future tense passive voice is "will be + past participle". T: Very good, Lily. 8. Homework T: For today's homework, first, review all the knowledge we learned in Module 9, including new words, phrases, grammar, and passages.
