Unit 10 I've had this bike for three years Section A 2a-2d 英文教案 2024-2025学年人教版（2012）八年级英语下册

Unit 10 I've had this bike for three years.-Section A-2a-2d 【教学目标】 Language Ability: Apply present perfect tense with "for/since" in dialogues, understand "while" guiding past continuous tense (e.g., "While she was reading, he called"). Cultural Awareness: Explore American yard sale culture, compare it with Chinese second-hand markets. Thinking Quality: Infer speakers' emotions through context (e.g., reluctance to part with toys). Learning Ability: Summarize conversation structures using flowcharts, practice listening for specific information. 【教学重难点】 Grammar: Differentiate "have/has been to" vs. "have/has gone to", master past continuous tense in embedded clauses. Vocabulary: Use "truthful", "hometown", "search for" correctly, understand collocations like "clear out", "no longer". Listening Skills: Catch time markers ("for 10 years") and emotional keywords ("hard to say goodbye") in fast speech. 【教学过程】 一、课程导入（Lead - in） T: Hello, class! How are you today? Before we start our new lesson, let's have a little chat. We learned about the present perfect tense in the last class. Now, I want you to look around the classroom and tell me something you can see using the present perfect tense. For example, you can say “I have seen this blackboard for two years.” Who wants to have a try? S1: I have seen this desk for one year. T: Great! You used the present perfect tense correctly. What else? S2: I have had this pencil for a month. T: Very good. It seems you all remember the grammar we learned. Now, let's think about this. Have you ever been to a yard sale? If you have, what kind of things did you see there? S3: I went to a yard sale once. I saw old toys and books. T: Good. Yard sales are really interesting. People sell all kinds of old things they don't need anymore. Today, we are going to continue learning about Unit 10 I've had this bike for three years. We will focus on Section A 2a - 2d. In this part, we will listen to more conversations about yard sales and learn how to talk about our feelings and experiences. 二、2a 部分教学（Pre - listening） T: First, look at the pictures in 2a. There are some things on sale at a yard sale, like a bread maker, a sweater, and a toy lion. Now, I want you to work in pairs and discuss what you think the sellers might say about these things. For example, if it's a toy car, the seller might say “I've had this toy car for five years. It's still in good condition.” Start your discussion. (Students start discussing in pairs. The teacher walks around and listens to their conversations.) T: Okay, stop here. Let's share some of your ideas. Who wants to talk about the bread maker? S4: The seller might say “I've had this bread maker for a long time. It makes delicious bread, but I don't use it much now.” T: Excellent! That's a very good description. How about the sweater? S5: Maybe the seller will say “I've had this sweater since last winter. It's very warm, but it's a bit small for me now.” T: Great job! You are really using your imagination. Now, let's move on to the listening part. Before we listen, look at the sentences in 2a. Try to predict what you might hear. 三、2a 部分教学（While - listening） T: （播放 2a 听力材料）Now, listen carefully and check (√) the things that the speakers are selling. (After the first listening) T: Okay, let's check the answers. What things are they selling? Ss: A bread maker, a sweater, and a toy lion. T: Right. Put a check next to these items. Now, let's listen again. This time, pay attention to the reasons why they are selling these things. (Play the recording again) T: Who can tell me why the woman is selling the bread maker? S6: She says she's had it for a long time and it's too big for her new apartment. T: Perfect. How about the sweater? Why is the girl selling it? S7: She's had it since she was a primary school student and it doesn't fit her anymore. T: Exactly. And the toy lion? S8: The boy has had it since his fourth birthday, but he doesn't play with it anymore. T: Great job, everyone. You listened very carefully. Now, you see how we can use the present perfect tense to talk about the things we are selling and the reasons. 四、2b 部分教学（Pre - listening） T: Look at 2b. There are some sentences about the prices and conditions of the items. Before we listen, let's read these sentences together and understand what they mean. (The teacher reads the sentences with the students.) T: Now, I want you to guess which item each sentence might be about. Discuss with your partner. (Students discuss in pairs.) T: Let's share your guesses. For the first sentence “It still works, but I don't use it often.” Which item do you think it's about? S9: Maybe the bread maker. T: Why do you think so? S9: Because the woman said she doesn't use the bread maker much although it still works. T: Good reasoning. How about the second sentence “It has special meaning to me because I played with it every day until I was about seven.” Which item could it be? S10: The toy lion. The boy said he played with it a lot when he was young. T: Right. You are all very smart. Now, let's listen to the recording and match the items with the sentences. 五、2b 部分教学（While - listening） T: （播放 2b 听力材料）Listen carefully and match the items with the sentences. (After the listening) T: Let's check the answers. What did you match for the bread maker? Ss: It still works, but I don't use it often. T: Correct. And the sweater? Ss: It's been in my family for a long time, but it's still in good condition. T: Right. And the toy lion? Ss: It has special meaning to me because I played with it every day until I was about seven. T: Well done. Now, let's listen again and repeat the sentences after the speakers. Try to imitate their pronunciation and intonation. (Play the recording again. Students repeat after the speakers.) T: Very good. Your pronunciation is getting better. Now, you know how to describe the items, their conditions, and the reasons for selling them. 六、2c 部分教学（Speaking practice） T: Now, it's time for you to practice speaking. Work in pairs. One of you will be the seller and the other will be the buyer. Use the information in 2a and 2b to make a conversation. The seller should introduce the item, its condition, the reason for selling, and the price. The buyer can ask questions. I'll give you an example. T: Seller: Hi, I'm selling this bread maker. I've had it for three years. It still works very well, but it's a bit too big for my new kitchen. Buyer: Oh, I see. How much is it? Seller: I'm selling it for 50 yuan. Buyer: Can you make it a little cheaper? Seller: Well, how about 45 yuan? Buyer: Okay, I'll take it. T: Now, start your own conversations. You can also add some of your own ideas. (Students start practicing in pairs. The teacher walks around and offers help and guidance.) T: （After a while）Okay, stop here. Let's invite some pairs to come to the front and show us their conversations. Pair 1 comes to the front: S11 (Seller): Hi, I'm selling this sweater. I've had it since I was in primary school. It's still in good condition, but it's too small for me now. S12 (Buyer): Oh, it looks nice. How much is it? S11: I'm selling it for 30 yuan. S12: Is there any discount? S11: Hmm, I can give you a 10% discount. So it's 27 yuan. S12: Alright, I'll buy it. T: Well done, you two. Your conversation is very natural and you used the language we learned very well. Let's give them a big hand. （Claps）Who else wants to show? Pair 2 comes to the front: S13 (Seller): Hello, I have this toy lion for sale. I've had it since my fourth birthday. It has special meaning to me, but I don't play with it anymore. S14 (Buyer): How much do you want for it? S13: I'm asking for 20 yuan. S14: Can you lower the price? S13: Okay, 15 yuan. That's the lowest price. S14: Fine, I'll take it. T: Excellent! You also did a great job. 七、2d 部分教学（Reading and role - playing） T: Now, let's look at 2d. Here is a conversation between Sarah and her mom. First, let's read the conversation silently and try to understand the main idea. (Students read the conversation silently.) T: What is the main idea of this conversation? S15: Sarah and her mom are cleaning out the house and deciding what to keep and what to sell at the yard sale. T: Right. Now, let's read the conversation aloud. I'll be Sarah's mom, and I need two volunteers to be Sarah and Sarah's dad. (Choose two students to be Sarah and Sarah's dad. Read the conversation aloud.) T: Very good. Now, let's analyze some important sentences in this conversation. “We've decided to each sell five things that we no longer use.” What does “no longer” mean? S16: It means “not ... anymore”. T: Exactly. Another sentence, “My son was quite sad at first.” Why was he sad? S17: Because he had to part with some of his favorite toys. T: Right. Now, I want you to work in groups of three. One person is Sarah, one is Sarah's mom, and one is Sarah's dad. Practice the conversation and then role - play it for the class. Try to act it out as vividly as possible. (Students practice in groups. The teacher moves around to offer help.) T: Okay, let's start the role - playing. Which group wants to come to the front first? Group 1 comes to the front and role - plays the conversation. T: Well done, group 1. Your acting is very good and you read the sentences clearly. Let's have another group. (Another group comes to the front and role - plays.) T: Excellent! You all did a great job. Through this role - playing, you can better understand the conversation and the language used. 八、课堂总结（Summary） T: Class, today we learned more about using the present perfect tense to talk about things at a yard sale, including describing the items, their conditions, the reasons for selling, and the prices. We also practiced speaking through conversations and role - playing. Remember to use these expressions in your daily life when you talk about your old things. You all made great progress today. 九、作业布置（Homework） T: For homework, I want you to write a short passage about a yard sale you have been to or imagine you are going to have. Include the things you saw or plan to sell, their conditions, the reasons for selling, and the prices. Also, practice the conversations in 2c and 2d with your family or friends.
