Unit 4 I used to be afraid of the dark.-Section AGrammar Focus-4c 教案-2025-2026学年人教版（2012）九年级英语全册

教学设计 课题 Unit 4 I used to be afraid of the dark.-Section A-Grammar Focus-4c 课时 1 教学目标 Language Competence: Master the grammatical structure "used to + verb 原形" for past habits and differentiate it from "be used to doing" (accustomed to) and "be used to do" (passive usage). Cultural Awareness: Explore how cultural contexts influence expressions of personal changes, such as comparing attitudes toward personal growth in different societies. Thinking Ability: Analyze sentence patterns to logically distinguish between past and present states, and summarize grammatical rules through comparative examples. Learning Ability: Develop self-study strategies (e.g., mind maps) to organize grammar points and apply rules in practical exercises. 重难点 Key Point: Correct application of "used to do" in affirmative, negative, and interrogative forms (e.g., "Did she use to...?"). Difficult Point: Avoiding confusion between "used to" (past habits) and "be used to" (present habits / 被动用法). Practice through contextual sentences (e.g., "He used to smoke" vs. "He is used to smoking") to solidify distinctions. 教学环节 学习活动 新课教学 一、开场引入（约 5 分钟） T（Teacher）: Good morning/afternoon, dear students! How are you today? Are you ready for an exciting English class? Before we start, let's have a little warm - up. I will show you some pictures of famous people when they were young and now. You need to guess who they are. T: （Show a picture of a young and current Jay Chou） Look at this boy. He was a little shy and thin. And now, he is a very famous and cool singer. Who is he? S（Students）: Jay Chou! T: Exactly! Jay Chou used to be a little shy, but now he is full of confidence on the stage. This leads us to our new grammar point today - “used to”. We use “used to” to talk about things we did regularly in the past but no longer do. 二、讲解 Grammar Focus（约 10 分钟） T: Now, open your books to Grammar Focus on Page XX. Let's read these sentences together. T & S: Mario used to be short, didn't he? Yes, he did. Now he's tall. Did you use to play the piano? Yes, I did./ No, I didn't. I used to be quiet. I didn't use to be short. T: First, let's focus on the positive form of “used to”. When we want to say that someone did something in the past but doesn't do it now, we use “used to + verb 原形”. For example, in the sentence “Mario used to be short”, the action “be short” was true in the past for Mario, but not now. Can you give me another example like this? Raise your hands. S1: I used to play basketball every weekend. T: Great! That means you don't play basketball every weekend now. Now, let's look at the negative form. In the sentence “I didn't use to be short”, we make the negative of “used to” by using “didn't” and then “use to” (note that we change “used” to “use”). So, if I want to say I didn't go to the park often in the past, how should I say it? S2: I didn't use to go to the park often. T: Perfect! Now, for the questions. When we want to ask if someone used to do something, we start with “Did”, then the subject, and “use to + verb 原形”. For example, “Did you use to play the piano?” How do we answer this kind of question? S3: Yes, I did. / No, I didn't. T: Right. The short answers are very simple. Just use “did” or “didn't” according to the truth. 三、4a 练习讲解（约 5 分钟） T: Now, let's move on to 4a. Look at the four people in the pictures and the words below. We need to write sentences about what they used to do and what they didn't use to do. Let's take the first one, Grace, as an example. The words are “watch a lot of TV/watch a lot of movies”. We can write “Grace used to watch a lot of TV. She didn't use to watch a lot of movies.” Do you understand? S: Yes. T: Now, work in pairs. Each pair chooses two of the people in 4a and writes sentences. Then, we will share our answers. (Students work in pairs. The teacher walks around to offer help and monitor the progress.) T: Time's up. Let's share. Which pair wants to start? S4: We chose the second one, about the mom. My mom used to have curly hair. She didn't use to have straight hair. T: Very good. The description is clear. What about another pair? S5: We did the third one. Jerry used to read books on European history. She didn't use to read books on African culture. T: Great job. Your sentences are all correct. Now, let's check all the answers together on the screen. 四、4b 练习讲解（约 10 分钟） T: Next, 4b. Here we have a chart about Emily. It shows her habits five years ago and now. We need to write sentences about her changes. First, look at the first row. Five years ago, she didn't eat a lot of vegetables, and now she loves carrots and tomatoes. How can we write sentences about this? S6: Emily didn't use to eat a lot of vegetables, but now she loves carrots and tomatoes. T: Exactly. Now, you work alone to write sentences for the rest of the information in the chart. Remember to use “used to” for the past and the simple present tense for the present. (Students write sentences. The teacher checks students' work and helps those who have difficulties.) T: Let's check the answers. Who wants to read their sentences? S7: Emily used to listen to pop music, but now she enjoys country music. T: Good. Another one? S8: Emily used to watch scary movies, but now she hates scary movies. T: Correct. And the last one? S9: Emily didn't use to read a lot of books, but now she reads at least six books a year. T: Well done, everyone. You all did a great job. 五、4c 小组活动（约 5 分钟） T: Now, it's time for our group work - 4c. In this activity, we are going to do a survey. I will divide you into groups of four. Each group member needs to answer the questions in 4c about what they used to be afraid of and what they are still afraid of. The topics are the dark, being alone, flying, high places, giving a speech in public. After you finish asking and answering, the group leader needs to write down the results and report to the whole class. (The teacher divides students into groups.) T: Start your survey now. Remember to use the sentences we learned today, like “Did you use to be afraid of...?” and “Yes, I did. / No, I didn't.” (Students do the survey in groups. The teacher moves around the classroom, listening to their conversations and providing guidance.) T: Time's up. Group leaders, are you ready to report? Let's start with Group 1. Group 1 Leader: In our group, Tom used to be afraid of the dark, but now he isn't. Lily used to be afraid of being alone and she is still afraid of it. Jack didn't use to be afraid of flying, and he still isn't. I used to be afraid of high places, and I'm still a little scared. T: Thank you, Group 1. Your report is very detailed. Let's hear from Group 2. (Each group reports their results in turn.) T: Wow, it's really interesting to know about your past and present fears. We can see that people change over time. 六、总结（约 5 分钟） T: OK, class. Let's summarize what we learned today. We learned the grammar point “used to”. We know how to use it in positive sentences, negative sentences, and questions. We used “used to” to talk about past habits or states that are different from the present. We also did a lot of exercises in 4a, 4b, and 4c to practice using “used to”. Remember, practice makes perfect. You can use “used to” to talk about other changes in your life, such as changes in hobbies, appearance, or personality. 七、作业布置（约 5 分钟） T: For homework, I want you to write a short passage about your own changes. You need to use at least five sentences with “used to”. You can talk about how you used to look, what you used to like to do, or what you used to be afraid of. And bring it to class tomorrow to share with your classmates. Also, review what we learned today and be ready for a little quiz in the next class. That's all for today's class. Have a great day! 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 $$
