Today, we're going to continue our exploration of Unit 10, "You're supposed to shake hands." We've already started discussing different customs around the world. Can anyone recall some of the customs we talked about in the last class? Raise your hands, please. Student 1: In the US, people usually shake hands when they meet for the first time. Teacher: Very good! What else? Student 2: In Japan, they bow. Teacher: Exactly! Different countries, different customs. Now, let's dive deeper into how we talk about these customs using grammar. 讲解 Grammar Focus Teacher: First, look at the sentences in the Grammar Focus box on page [X]. Let's read them together. "What are you supposed to do when you meet someone for the first time? You're supposed to shake hands. You're not supposed to kiss." Now, who can tell me what structure we are using here? Student 3: "be supposed to". Teacher: Right! The structure "be supposed to" is very useful. When the subject is a person, it means "should" or "are expected to". It can be used to give advice, talk about customs, obligations, or responsibilities. For example, if I say, "You're supposed to wear a seatbelt in the car," what does it mean? Student 4: It means we should wear a seatbelt. Teacher: Correct! Now, let's make some more examples. Suppose you are in a library. What are you supposed to do? And what are you not supposed to do? Discuss with your partner for a minute. (Students discuss) Teacher: Okay, time's up. Who wants to share? Student 5: You're supposed to be quiet in the library. You're not supposed to talk loudly. Teacher: Excellent! Another example. When you go to a friend's house for dinner in China, what are you supposed to do? Student 6: You're supposed to bring a small gift. Teacher: Great! And what about what you're not supposed to do? Student 7: You're not supposed to arrive too early or too late. Teacher: Perfect! Now, let's look at the negative form. "be not supposed to" means you shouldn't do something. It's like a rule or a social norm that you should avoid. For example, "You're not supposed to eat with your hands in a formal Western dinner." Can you give me another example? Student 8: You're not supposed to smoke in a hospital. Teacher: Exactly! Now, let's practice changing some sentences into the "be supposed to" structure. I'll give you a sentence, and you change it. Ready? "We should respect our elders." Student 9: We're supposed to respect our elders. Teacher: Well done! Now, "You should not litter in the park." Student 10: You're not supposed to litter in the park. Teacher: Super! Let's move on to the question form. We can ask, "What are we supposed to do?" or "Am I supposed to...?" For example, "Am I supposed to bring my textbook to the class every day?" How would you answer? Student 11: Yes, you're supposed to bring your textbook to the class every day. Teacher: Right! Now, I'll ask you some questions, and you answer using the "be supposed to" structure. "What are you supposed to do when the traffic light is red?" Student 12: We're supposed to stop. Teacher: Great! "Am I supposed to wear a uniform at school?" Student 13: Yes, you're supposed to wear a uniform at school if your school has a uniform policy. Teacher: Excellent! 4a 练习讲解 Teacher: Now, let's look at Exercise 4a on page [X]. We have some sentences here, and we need to fill in the blanks with the correct form of "be supposed to", "be expected to", or "be important to". First, read the sentences by yourself and try to think about the answers. (Students read the sentences) Teacher: Let's go through them one by one. The first sentence is "When you go abroad, it ______ bring your passport." What should we fill in here? Student 14: is important to. Teacher: Why do you think so? Student 14: Because it's very important to bring your passport when you go abroad. Teacher: Right! It's a very important thing. Now, the second sentence, "After class, students ______ clean the chalk off the blackboard." Student 15: are supposed to. Teacher: Good! In a school setting, it's a common practice or an expectation for students to clean the chalk off the blackboard after class. Now, the third sentence, "If you visit the northern coast of Norway during the winter season, it ______ pack warm clothes." Student 16: is important to. Teacher: Exactly! In a cold place like the northern coast of Norway in winter, packing warm clothes is really important. The fourth sentence, "If there are people in the meeting room, you ______ knock before entering." Student 17: are expected to. Teacher: Great! It's a polite behavior that people expect you to do. The last sentence, "In many eastern European countries, you ______ take off your gloves before shaking hands." Student 18: are supposed to. Teacher: Right! It's a cultural custom in many eastern European countries. Now, let's check the answers together on the board. 4b 练习讲解 Teacher: Next, let's move on to Exercise 4b. In this exercise, we need to fill in the blanks with the correct forms of the words in brackets. First, read the passage carefully. Try to understand the context and think about how to use the "be supposed to" structure. (Students read the passage) Teacher: Let's start. The first blank, "A traveler ___________________ (not expect; know) all of these". What should we put here? Student 19: isn't expected to know. Teacher: Good! A traveler is not expected to know all the customs of a foreign country. Now, the second blank, "but it is helpful _______ (learn) as many of these customs as possible." Student 20: to learn. Teacher: Right! It's helpful to learn about different customs. The third blank, "One of the best ways to be accepted in a foreign country is to try _____________ (understand) how people think." Student 21: to understand. Teacher: Exactly! Understanding how people think is important. The fourth blank, "Learning what you ________________ (suppose; do) and _________________ (not suppose; do) in social situations may be difficult." Student 22: are supposed to do; are not supposed to do. Teacher: Perfect! We use the correct forms of "be supposed to" here to talk about what is expected and not expected in social situations. Now, let's read the passage together with the correct answers filled in. 4c 小组讨论 Teacher: Now, for Exercise 4c, we're going to do a group activity. I'll divide you into groups of four. In your groups, you need to give advice about different situations. The situations are: time (like what time to arrive for different events), what to do for someone's birthday, meeting people, visiting someone's home, table manners, and coming to our country as an exchange student for the first time. Each group member can take one or two situations and start thinking about the advice. You can use the "be supposed to" structure. For example, for "meeting people", you can say, "When you meet people for the first time in our country, you're supposed to smile and say hello." Now, start discussing in your groups. (Students form groups and start discussing) Teacher: (Walk around the classroom, listen to the students' discussions, and offer help or guidance when needed) Teacher: Okay, time's up. Each group, please choose a representative to share your group's advice. Let's start with Group 1. Group 1 Representative: For time, when you're invited to a party, you're supposed to arrive 10 - 15 minutes late. For someone's birthday, you're supposed to bring a gift. When meeting people, you're supposed to shake hands. When visiting someone's home, you're supposed to take off your shoes at the door. For table manners, you're supposed to use chopsticks correctly. When coming to our country as an exchange student for the first time, you're supposed to learn some basic greetings in our language. Teacher: Great job, Group 1! Now, Group 2, your turn. Group 2 Representative: When it comes to time, if it's a business meeting, you're supposed to arrive on time. For a birthday, you're supposed to write a birthday card. When meeting people, you're supposed to look them in the eye. When visiting someone's home, you're supposed to bring a small gift like fruits. For table manners, you're not supposed to talk with your mouth full. When coming as an exchange student, you're supposed to respect our local customs. Teacher: Wonderful! Group 3, please. Group 3 Representative: For time, if it's a wedding, you're supposed to arrive a little early. For someone's birthday, you're supposed to sing the birthday song. When meeting people, you're supposed to introduce yourself clearly. When visiting someone's home, you're supposed to ask if you can use the restroom. For table manners, you're supposed to wait for the host to start eating. When coming as an exchange student, you're supposed to join in the local activities. Teacher: Excellent advice from all the groups! Now, let's summarize what we've learned today. 课堂总结 Teacher: Today, we focused on the "be supposed to" structure. We learned how to use it to talk about customs, obligations, and what is expected in different situations. We practiced making sentences in the affirmative, negative, and question forms. We also completed Exercises 4a, 4b, and 4c, which helped us apply this grammar in different contexts. Remember, understanding different customs and how to talk about them is very important, especially in our globalized world. For homework, I want you to write a short passage about the customs in your family using the "be supposed to" structure. It should be at least 10 sentences long. You can talk about things like what you're supposed to do during festivals, when guests come, or at the dinner table. Bring it to class tomorrow, and we'll share them. That's all for today. Class is dismissed. 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 学科网（北京）股份有限公司 $$
