Who can tell me some common ways of communication we talked about? Yes, [Student's Name]? Student: We learned about talking face to face, making a phone call, sending text messages, and making a video call. Teacher: Excellent! You remembered very well. And do you still remember how to use "if" - clauses to talk about assumptions and results? For example, if I say, "If it rains tomorrow", how would you complete the sentence? [Another Student's Name]? Student: If it rains tomorrow, I will stay at home. Teacher: Perfect! Now, let's move on to today's new content - the vocabulary in Section B. Open your books to the relevant page. First, look at the word "pay". We know it has several meanings. Can anyone give me an example sentence using "pay" as "to give money for something"? [Student raises hand] Yes, please. Student: I paid 20 yuan for this book. Teacher: Great! "Pay" here shows that you gave 20 yuan to get the book. The structure is "pay + money + for sth". Now, let's look at another usage. When we say "It takes sb. some time to do sth", what does "take" mean in this sentence? It's different from "pay". [Think for a moment] Let's see an example, "It takes me 30 minutes to get to school by bike." What does "take" refer to here? [Call on a student] Student: It means the time needed to do something. Teacher: Exactly! Here, "take" indicates the amount of time it requires for someone to complete an action. The subject is usually "it", and the structure is "It takes + sb. + some time + to do sth". Now, let's compare "pay" and "take". Who can tell me the main difference between them? [Student volunteers] Student: "Pay" is mainly about giving money, and "take" is about the time needed for an action. Teacher: Very good! Now, let's look at the word "cost". "Cost" is also related to money. But there's a difference. For example, "This bike costs me 300 yuan." Who can find out the difference between "cost" and "pay" according to this sentence? [Ask students to think and discuss in pairs for a while, then call on someone] Student: For "pay", the subject is a person, like "I pay...", but for "cost", the subject is the thing, like "This bike costs...". Teacher: You are so smart! That's the key difference. "Cost" has the structure "Sth. costs sb. + money". Now, let's practice. I'll give you some situations, and you need to use "pay", "take", or "cost" to make sentences. The first situation: You buy a movie ticket for 50 yuan. How do you make a sentence using "pay"? [Student answers] Student: I pay 50 yuan for the movie ticket. Teacher: Right! The second situation: It usually needs 2 hours for you to finish your homework. Use "take" to make a sentence. [Another student answers] Student: It takes me 2 hours to finish my homework. Teacher: Great! The third situation: This beautiful dress is worth 200 yuan to you. Use "cost" to make a sentence. [Student responds] Student: This beautiful dress costs me 200 yuan. Teacher: Wonderful! Now, let's move on to the next word, "offer". "Offer" has different meanings and usages. When it means "to provide", we can say "offer sth. to sb." or "offer sb. sth". For example, "He offered me a glass of water." It can also mean "to say that you are willing to do sth. for sb.", like "She offered to help me with my English." Now, I want you to make your own sentences using these two usages of "offer". [Give students some time to write sentences, then ask them to share] Student 1: My friend offered a seat to an old man on the bus. Student 2: I offered to clean the classroom after school. Teacher: Both of your sentences are correct and very good! Now, let's look at the word "reasonable". It means fair and sensible. For example, "The price of this shirt is reasonable." Can you give me another example using "reasonable"? [Student gives an answer] Student: His suggestion is very reasonable. Teacher: Perfect! Now, let's talk about the word "medium". When we talk about communication, we often use "medium" to mean a way or method. For example, "Social media is a very popular medium of communication nowadays." Can you think of other examples of communication mediums and make sentences? [Students think and answer] Student: Newspapers are also a medium of getting information. Teacher: Excellent! Now, let's do a little exercise. I'll show you some sentences on the screen, and you need to fill in the blanks with the correct words we just learned. [Show sentences on the PPT] I _ 10 dollars for the ice - cream. (pay) It _ her an hour to finish the painting. (takes) The new computer _ me a lot of money. (costs) He _ to carry the heavy box for me. (offered) His plan sounds very _. (reasonable) Television is an important _ of communication. (medium) [Ask students to answer one by one] Teacher: Great job, everyone! You all did very well. Now, let's play a little game. I'll describe a situation, and you need to quickly use the words we learned to make a sentence related to the situation. For example, if I say "You go to a restaurant and eat a meal", you can say "I paid 50 yuan for the meal in the restaurant." Are you ready? Here we go. "You want to buy a new pair of shoes in the store." [Student responds] Student: I will pay some money for the new pair of shoes in the store. Teacher: Good! Next, "It usually needs 30 minutes for you to go to the library by bus." [Another student answers] Student: It takes me 30 minutes to go to the library by bus. Teacher: Perfect! "The new smartphone you want to buy is very expensive." [Student makes a sentence] Student: The new smartphone costs a lot of money. Teacher: Great! "Your classmate sees you carrying a heavy bag and wants to help you." [Student gives a sentence] Student: My classmate offered to help me carry the heavy bag. Teacher: Excellent! "Your teacher gives you a plan for the study, and you think it's good." [Student answers] Student: My teacher's plan for the study is very reasonable. Teacher: Well done! "You often use the Internet to talk to your friends far away." [Student makes a relevant sentence] Student: The Internet is a very useful medium for me to communicate with my friends far away. Teacher: Fantastic! You all did an amazing job. Now, let's summarize what we learned today. We learned several important words like "pay", "take", "cost", "offer", "reasonable", and "medium", and their different usages. Remember these words and try to use them in your daily English communication. After class, please do the relevant exercises in your workbook to further practice these words. That's all for today's class. Goodbye, class! 学科网(北京)股份有限公司 学科网(北京)股份有限公司 学科网(北京)股份有限公司 $$
