Before we start our new lesson, let's have a quick review. Remember in Section A, we talked about some amazing geographical facts. So, who can tell me what's the highest mountain in the world? Raise your hands, please. S1: Qomolangma! T: Exactly! Qomolangma is the highest mountain in the world. Can you describe it using the comparative or superlative sentences we learned? S2: Qomolangma is higher than any other mountain in the world. T: Very good! What about the deepest salt lake in the world? S3: The Caspian Sea. T: Right! The Caspian Sea is the deepest of all the salt lakes. Now, let's move on to our new topic. Look at the screen. What can you see? (Show pictures of an elephant and a panda) Ss: An elephant and a panda. Presentation T: Yes, we are going to talk about animals today. First, let's focus on these two lovely animals, the elephant and the panda. Look at the information in 1a. We have some facts about them. Let's read them together. “This elephant is about 350cm tall.” Read it again. Ss: This elephant is about 350cm tall. T: “This elephant weighs 5,000 kilos.” Follow me. Ss: This elephant weighs 5,000 kilos. T: Now, look at the panda. “This panda is about 150cm long.” Read. Ss: This panda is about 150cm long. T: “This panda weighs 100 kilos.” Read after me. Ss: This panda weighs 100 kilos. T: We can see that they are quite different in height and weight. Now, let's try to make some sentences to compare them. For example, we can say “This elephant is taller than this panda.” Can you make other sentences like this? Think about it and then share with your partners. (Students discuss in pairs) T: Stop here. Who wants to share your sentences? S4: This elephant weighs more than this panda. T: Good! Any other sentences? S5: This panda is shorter than this elephant. T: Excellent! Now, look at this language point. When we want to express how many times one thing is bigger, heavier, etc. than another, we can use “倍数 + 比较级 + than”. For example, “This elephant weighs many times more than this panda.” Here, “many times” shows the multiple. Let's make some sentences using this structure. First, look at the example again. Try to make your own sentences with your partner. (Students practice making sentences) T: OK, time's up. Who would like to show us your sentences? S6: This elephant is many times taller than this panda. T: Great! Another one? S7: This panda is many times lighter than this elephant. T: Well done! You all did a good job. Now, let's learn some new words. Look at the word “weigh”. It means to have a particular weight. For example, “The box weighs 5 kilos.” Read the word and the sentence together. Ss: weigh; The box weighs 5 kilos. T: Next, “birth”. It means the time when someone is born. “At birth, the baby was very small.” Read. Ss: birth; At birth, the baby was very small. T: And “adult”. It means a grown - up person or animal. “An adult panda looks different from a baby panda.” Read. Ss: adult; An adult panda looks different from a baby panda. T: Also, we have two important phrases. “At birth” we just saw in the sentence. And “live up to” means to reach a particular age. For example, “A panda can live up to 20 to 30 years.” Read these two phrases and the example sentence. Ss: at birth, live up to; A panda can live up to 20 to 30 years. Listening T: Now, let's move on to the listening part. First, look at the numbers in 1b. Read them out loud. Ss: 100, 16, 20, 50, 120, 0.1, 0.2, 150. T: Listen carefully. The recording will talk about some facts about pandas. Check the numbers you hear. Are you ready? Here we go. (Play the recording for the first time) T: Stop. Let's check the answers. Which numbers did you hear? S8: 100, 0.1, 0.2, 150. T: Correct. Now, let's listen again. This time, try to guess the answers to the questions in 1c. For example, the first question is “How heavy is a baby panda at birth?” Listen and think about the answer. (Play the recording for the second time) T: OK, let's stop. Now, let's complete the sentences in 1c. Start with the first one. How heavy is a baby panda at birth? S9: At birth, a baby panda is about 0.1 to 0.2 kilos. T: Right. What about the second one? How long is a baby panda at birth? S10: At birth, a baby panda is about 15cm long. T: Good. And the third one? How much does an adult panda weigh? S11: An adult panda weighs about 100 kilos. T: Correct. Now, let's listen one more time to make sure all the answers are right. (Play the recording for the third time) T: Check your answers again. Are there any mistakes? If you have any questions, raise your hands. (Students check and ask questions if there are any) T: Very good. You all did a great job in listening. Groupwork T: Now, it's time for our groupwork. We are going to talk more about pandas. Take turns telling your classmates about pandas. You can use the information we learned today and your own knowledge. For example, you can start like this: “A baby panda cannot see.” Then the next one can say something else, like “An adult panda weighs many times more than a baby panda.” I will give you 5 minutes to discuss in your groups. Then each group will choose one person to share your ideas with the whole class. (Students work in groups) T: Time's up. Which group wants to share first? Group 1 representative: A baby panda is very small at birth. It is only about 15cm long and weighs 0.1 to 0.2 kilos. An adult panda can eat a lot of bamboo every day. It can live up to 20 to 30 years. T: Wonderful! You shared a lot of interesting facts about pandas. What about the next group? Group 2 representative: A baby panda looks very different from an adult panda. At birth, it is pink and has no teeth. An adult panda is black and white and much bigger. It can stand on two legs sometimes. T: Great job! You described the differences between baby and adult pandas very clearly. Let's give them a big hand. Now, from what we've learned today, we can see that pandas are really special animals. But they are also endangered. We should do our best to protect them. Summary T: Let's summarize what we've learned today. First, we compared an elephant and a panda using comparative sentences and the “倍数 + 比较级 + than” structure. Then we learned some new words like “weigh”, “birth”, “adult” and phrases “at birth”, “live up to”. We also listened to some facts about pandas and completed the related tasks. And finally, we shared more information about pandas in our groupwork. Remember these important points. Homework T: For your homework today, I want you to write a short passage about an animal you like. Use the comparative sentences and the new words and phrases we learned. You can also use some other information you know about the animal. Write at least 8 sentences. And don't forget to check your spelling and grammar. I will collect your homework tomorrow. That's all for today's class. Class is over. Goodbye, everyone! Ss: Goodbye, teacher! 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 $$
