Today, we are going to start an exciting journey. First, let me show you some pictures. Look at these pictures. What a wonderful place! Can you guess where it is? 学生们：Camping site! 老师：Exactly! It's a camping site. Many people like to go camping during their holidays. They can enjoy the beauty of nature, breathe fresh air, and have a great time with their families or friends. Now, I want you to imagine that you are in this beautiful camping site. How do you feel? Raise your hands and share your feelings with us. 学生 A：I feel relaxed and happy. 老师：Great! I'm sure you do. What about you, student B? 学生 B：It's exciting. I can do a lot of interesting things there. 老师：That's right. Camping is really exciting. But, 同学们，when we are camping, are there any things we need to pay attention to? Are there any rules we should follow? Now, turn to your partners and discuss this question for one minute. Then, I will invite some of you to share your ideas. 词汇讲解 老师：Time's up! Let's stop here. Who wants to share your ideas about the camping rules? Student C, please. 学生 C：We should not make too much noise. 老师：Very good! Making too much noise may disturb others. We must keep quiet in the camping site. （板书 “must keep quiet”，并划出 “must”）Here, we use “must” to show that it's a very important rule we have to follow. “Must” is a modal verb, and it is always followed by the base form of a verb. For example, we say “We must keep quiet.” not “We must keeps quiet.” or “We must to keep quiet.” Understand? 学生们：Yes. 老师：Good. Now, let's learn some new words related to camping. （展示帐篷的图片）What's this in English? 学生们：Tent. 老师：Correct. Read after me, tent. （带领学生读几遍）Tent is where we sleep when we camp. Next one. （展示一个人摔倒的图片）What's happening to this person? 学生 D：He is falling. 老师：Right. The word is “fall”. Fall means to drop or come down from a higher position. Read after me, fall. （领读）Now, let's see another word. （展示一张树上挂着东西的图片）What can you see? 学生 E：There is something hanging on the tree. 老师：Great. The word “hang” means to attach or suspend something. Read after me, hang. （继续领读新单词 “sudden”“gun”“soft”“still”“wood”“blood”，并结合图片或简单的动作帮助学生理解，每个单词都让学生跟读几遍） 老师：Now, let's play a little game. I will say a word, and you need to quickly think of a sentence using that word. For example, if I say “tent”, you can say “We put up the tent near the river.” Are you ready? Let's start with “fall”. Student F, please. 学生 F：Be careful, or you will fall down. 老师：Well done! Now, “hang”. Student G. 学生 G：I hang my clothes on the line to dry. 老师：Very good. Let's continue with “sudden”. 课文讲解 老师：After learning these new words, let's move on to our text. Open your books to the passage about camping. Before we read, look at the picture on the page. What is the bear doing? And what do you think the people in the tent should do? Discuss with your partners for half a minute. （学生们讨论后） 老师：Time's up. Who can tell me what the bear is doing? Student H. 学生 H：The bear is standing outside the tent. 老师：Good. And what should the people in the tent do? Student I. 学生 I：They should stay still and not make any noise. 老师：That's a great suggestion. Now, let's read the passage quickly and find out the main idea. Try to answer this question: What is the passage mainly about? Start reading. （学生们快速阅读后） 老师：Finished? Who can tell me the main idea of this passage? Student J. 学生 J：It's about a camping trip and what they should do when they meet a bear. 老师：Exactly. The passage tells us about the writer's camping experience and some important rules they need to follow to keep safe. Now, let's read the passage carefully. I will ask some detailed questions. In the middle of the first night, what did the writer hear outside? Student K. 学生 K：The writer heard a noise outside. 老师：Right. And what happened to the bag of food? Student L. 学生 L：The bear opened the bag of food. 老师：Good. During the second night, what did the bears do? Student M. 学生 M：The bears came again and took the food from the tree. 老师：Very good. Now, let's find out what they should or should not do according to the passage. On the first day, after walking for about eight hours, they were tired. So, they should put up the tent and have a rest. What else should they do to keep the camp clean? Discuss in your groups for one minute and then share your answers. （学生们分组讨论后） 老师：OK, let's stop. Which group wants to share your ideas? Group 1, please. 小组 1 代表：They should not throw rubbish everywhere. They must keep the camp clean. 老师：Great! We must keep the camp clean. This is a very important rule. （再次强调 “must keep the camp clean”，并解释为什么要保持营地干净，如防止吸引野生动物、保护环境等）What else? Group 2. 小组 2 代表：They should hang the food in the tree to keep it safe from bears. 老师：Yes, that's a good way. Bears can smell food from far away. Hanging the food in the tree can prevent the bears from getting it easily. Now, let's look at another part. On the fourth day, what did the writer see? And what should he not do? Student N. 学生 N：The writer saw a baby bear playing with some sticks and stones. He should not make any sudden moves. 老师：Exactly. Making sudden moves may scare the bear and cause danger. We must be very careful when we are around wild animals. Now, let's read the passage together to have a better understanding. 语法讲解 老师：After reading the passage, let's focus on the grammar. In the passage, we saw many sentences using “must”. For example, “We must keep the camp clean.” “You must not make any sudden moves.” Can you tell me the function of “must” here? Discuss with your partner for half a minute. （学生们讨论后） 老师：Time's up. Who can tell me the function of “must” in these sentences? Student O. 学生 O：It shows that something is necessary or important to do. 老师：Very good. “Must” is used to express obligation or necessity. When we say “We must do something”, it means it is our duty or it is very important for us to do that thing. And when we say “We must not do something”, it means it is not allowed, it is prohibited. For example, “We must wear seat belts in the car.” It is very important for our safety. “We must not play with fire.” It is dangerous and not allowed. Now, I will give you some situations, and you need to use “must” or “must not” to make sentences. Situation 1: You are in a library. What should you do? Student P. 学生 P：We must keep quiet in the library. 老师：Good. Situation 2: You are crossing the road. What should you not do? Student Q. 学生 Q：We must not run across the road. 老师：Right. Now, another one. You are camping in the forest. What should you do to protect the environment? Group 3, please. 小组 3 代表：We must not cut down the trees. We must take our rubbish away. 老师：Excellent. Using “must” and “must not” correctly can help us express rules and suggestions clearly. Now, let's do some exercises on the screen to practice. 课堂练习 老师：（展示练习题，如用 “must” 或 “must not” 填空）Let's start with the first one. You ________ (must /must not) litter in the park. Student R, please. 学生 R：must not 老师：Correct. The second one. We ________ (must / must not) wash our hands before eating. Student S. 学生 S：must 老师：Good. Now, the third one. When you see a red light, you ________ (must / must not) stop. Student T. 学生 T：must 老师：Well done. Let's continue with the next exercise. This time, I will give you a sentence, and you need to change it using “must” or “must not”. For example, “It is important to wear a helmet when riding a bike.” You can change it to “We must wear a helmet when riding a bike.” Are you ready? “It is not allowed to smoke in the hospital.” Student U. 学生 U：We must not smoke in the hospital. 老师：Great. Now, another one. “It is necessary to lock the door when you leave home.” Student V. 学生 V：We must lock the door when we leave home. 老师：Very good. After doing these exercises, I can see that you have a better understanding of how to use “must” and “must not”. Now, let's move on to the next part. 小组讨论与展示 老师：Now, I want you to work in groups of four. Suppose you are going on a camping trip together. Make a list of rules and suggestions for your camping trip. You can use “must” and “must not” to express them. For example, “We must bring enough food and water.” “We must not forget to bring a map.” You have five minutes to discuss and write them down. Then, each group will choose a representative to share your list with the whole class. Start now. （学生们分组热烈讨论并记录，老师巡视各小组，给予必要的指导和帮助） 老师：Time's up. Which group wants to share your list first? Group 4, please. 小组 4 代表：（展示小组写的规则和建议并讲解）We must bring a tent and sleeping bags. We must not make a fire in the forest without permission. We must keep our campsite clean and tidy. We must not leave our things alone. 老师：Very good. Your rules are very practical. What about Group 5? 小组 5 代表：We must wear comfortable shoes. We must not go too far away from the campsite. We must bring a first - aid kit. We must not play loud music at night. 老师：Excellent. You have thought of many important aspects. Let's see what Group 6 has. 小组 6 代表：We must check the weather before we go. We must not feed the wild animals. We must bring some warm clothes. We must not waste water. 老师：Great job, everyone. All of your rules and suggestions are very useful. They can help us have a safe and enjoyable camping trip. 课堂总结 老师：Today, we have learned a lot about camping rules and suggestions. We learned some new words related to camping, and more importantly, we learned how to use “must” and “must not” to express rules and obligations. Can you tell me one important rule for camping that we learned today? Student W. 学生 W：We must keep the camp clean. 老师：Right. Keeping the camp clean is very important for both our safety and the environment. What else? Student X. 学生 X：We must not make sudden moves when we see a bear. 老师：Good. Remembering these rules can help us stay safe during our camping trips. Also, through this lesson, we should understand the importance of protecting the environment. When we camp, we should try our best to leave the place as clean as we found it. Now, let's summarize the key points of this lesson. （回顾重点词汇、语法和重要规则，强化学生记忆） 作业布置 老师：For today's homework, I have two tasks for you. First, write a short passage about your ideal camping trip. Include at least five rules and suggestions using “must” and “must not”. Second, share what you have learned today with your family and discuss with them some rules for outdoor activities. Next class, we will share your passages and discussions. Is that clear? 学生们：Yes. 老师：OK, 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 $$
