教学设计 课题 Unit 7 Teenagers should be allowed to choose their own clothes.-Section A-Grammar Focus-4c 课时 1 教学目标 Language Competence: Master modal verbs "should/shouldn’t be allowed to" to express permissions and obligations, and use them correctly in different tenses. Cultural Awareness: Understand cultural differences in teenagers’ rights to make choices, and respect diverse family and social values. Thinking Quality: Analyze the 合理性 (rationality) of rules through critical thinking, and express opinions logically. Learning Ability: Develop autonomous learning by summarizing grammar rules and practicing in real-life contexts. 重难点 Grammar: The passive voice with modal verbs (e.g., "Teenagers should be allowed to..."), focusing on the structure "modal verb + be + past participle". Usage: Distinguish between "should be allowed to" for suggestions and "must/have to" for obligations. Application: Apply the grammar to debate topics like "Should students choose their own uniforms?" with proper logic and examples. 教学环节 学习活动 新课教学 Teacher: Good morning, class! Let's start our lesson today. First, let's do a quick review. Yesterday, we talked about different things that teenagers should or should not be allowed to do. Can someone give me an example? Yes, [Student's Name]? Student: I think teenagers should be allowed to choose their own clothes. Teacher: Very good! That's exactly what our unit is about. Now, let's look at the Grammar Focus on the screen. Here, we have a lot of sentences using the structure "should be allowed to do sth." Can you read the first sentence together? Students: Sixteen-year-olds should not be allowed to work at night. Teacher: Great! Now, let's break down this structure. "Should" is a modal verb, and "be allowed to do sth." is the passive voice. The passive voice here shows that the action of "allowing" is done to the subject. In this case, "sixteen-year-olds" are the ones being considered for the action of being allowed or not allowed to work at night. Let's look at another example. "I think students should be allowed to do homework with friends." Who can tell me what the subject is and what action is being allowed to the subject? [Student raises hand] Yes, [Student's Name]? Student: The subject is "students", and the action being allowed is "to do homework with friends". Teacher: Perfect! You got it. Now, let's practice changing some active voice sentences into the passive voice with "should be allowed to". Here's an active voice sentence: "Parents should allow teenagers to have hobbies." How can we change this into the passive voice using our structure? Discuss with your partner for a minute. [Students discuss in pairs] Teacher: Okay, time's up. Who wants to share the answer? [Student raises hand] Yes, [Student's Name]? Student: Teenagers should be allowed to have hobbies by parents. Teacher: Almost right. We usually don't mention "by parents" if it's obvious who the doer is in this context. So the better answer is "Teenagers should be allowed to have hobbies." Let's do one more. "Teachers should allow students to use calculators in math class." What's the passive voice version? [Student raises hand] Student: Students should be allowed to use calculators in math class. Teacher: Excellent! Now, let's move on to 4c. Look at the situations in the box. We have things like "Choose your own clothes", "Go out on school nights", "Get your ears pierced", etc. I want you to work in groups of four. For each situation, discuss and write down two opinions - one saying teenagers should be allowed to do it and the other saying they should not be allowed to do it. You can use the structure we just learned. For example, for "Choose your own clothes", you can write "Teenagers should be allowed to choose their own clothes because it helps them express their individuality." and "Teenagers should not be allowed to choose their own clothes because they might choose inappropriate ones." Are there any questions? Students: No. Teacher: Okay, start working. [Students work in groups for about 5 minutes] Teacher: Alright, let's stop here. Which group wants to share their answers first? Group 1, please. Group 1 Student: For "Go out on school nights", we think teenagers should be allowed to go out on school nights because they need to relax after a busy day at school. But they should not be allowed to go out on school nights because they might stay out too late and not get enough sleep for school the next day. Teacher: Very good! You gave clear reasons for both opinions. What about Group 2? Share your answers for another situation. Group 2 Student: For "Get your ears pierced", we think teenagers should be allowed to get their ears pierced as it's a form of self-expression. However, they should not be allowed to get their ears pierced because it might be painful and there could be a risk of infection. Teacher: Great job, Group 2. Now, let's switch roles a bit. I'll give you some opinions, and you tell me which situation it might be related to. Listen carefully. "Teenagers should be allowed to do this because it can improve their social skills." Which situation from the box do you think this might refer to? [Student raises hand] Student: Maybe "Go out with friends". Teacher: That's a very good guess. It could definitely be related to going out with friends as it can help improve social skills. Now, another one. "Teenagers should not be allowed to do this because it can be dangerous for their health." What could this be about? [Student raises hand] Student: Maybe "Smoke cigarettes". But it's not in the box. Teacher: You're thinking outside the box, which is great. Although "Smoke cigarettes" is not in the box, you're right that it fits this description. Looking at the box, which one do you think is also related to danger for health? Student: "Drive a car without a license"? Teacher: Exactly! Teenagers should not be allowed to drive a car without a license as it's extremely dangerous. Now, let's review what we've learned today. We've practiced using the structure "should be allowed to do sth." in the passive voice. We've also discussed different opinions about what teenagers should or should not be allowed to do. Remember, when we use this structure, we are talking about the permission or lack of permission given to the subject. For homework, I want you to write a short passage about three things you think teenagers should be allowed to do and three things they should not be allowed to do. Use the structure we learned and give reasons for each of your opinions. Are there any questions before we end the class? Students: No. Teacher: Okay, class is over. 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 $$
