Unit 6 When was it invented Section A 3a～3c 教案-2024-2025学年人教版英语九年级全一册

Unit 6 When was it invented-Section A-3a-3c 【教学目标】 Language Competence: Analyze text structures (problem-solution) and master academic vocabulary (accidental，ruler), reinforcing passive voice in past tense. Cultural Awareness: Explore the historical background of tea invention and its cultural influence in ancient China. Thinking Quality: Infer implicit information (e.g., accidental invention logic) and summarize text main ideas through skimming & scanning. Learning Ability: Develop note-taking strategies and apply reading skills to retell invention stories collaboratively. 【教学重难点】 Key: Grasp reading techniques (identifying time/event chains) and understand complex sentences with passive voice. Difficult: Distinguish between "invention process" and "cultural impact", and link textual details (e.g., Shen Nong's role) to historical facts. Overcome vocabulary barriers (e.g., technical terms) to enhance reading comprehension accuracy. 【教学过程】 Teacher: Good morning, class! Before we start today's lesson, I have a question for you. After water, what is the most popular drink in the world? Any guesses? Students: Tea! Coffee! Teacher: Right! Tea is indeed the most popular drink in the world after water. And today, we are going to explore the fascinating story of how tea was invented. But first, let's do a little review. Look at this mind map on the board. Can someone come up and retell how tea is produced according to this mind map? (A student comes to the board and starts to retell) Student: First, tea plants are grown on the sides of mountains. Then, the leaves are picked by hand. After that, they are sent to the factory where they are processed. Finally, the tea is packed and sold. Teacher: Excellent! You've done a great job. Now, let's move on to our new lesson. Look at the title of the passage in 3a - "An Accidental Invention". And also, take a look at the picture. What can you see? Students: A man boiling water and some leaves falling into the pot. Teacher: Exactly. From the title and the picture, can you make a guess about what this passage might be mainly about? Student: Maybe it's about how something was invented by accident, like tea? Teacher: Very good prediction. Now, let's do some skimming. Read the passage quickly and match each paragraph with its main idea. I'll give you two minutes. Start! (Students start reading quickly) Teacher: Time's up. Let's check the answers. For paragraph 1, what's the main idea? Student: How tea was invented by accident. Teacher: Correct. And paragraph 2? Student: Lu Yu and his book Cha Jing. Teacher: Right. And paragraph 3? Student: How tea spread to other countries. Teacher: Perfect. Now, let's read paragraph 1 carefully. When was tea first drunk? Find the sentence in the paragraph that tells us. Student: Tea was first drunk nearly 5,000 years ago. Teacher: Great. And who invented tea? Student: It was invented by Shen Nong. Teacher: Exactly. The passage says "It is said that a Chinese ruler called Shen Nong was the first to discover tea as a drink." So, tea was invented by this Chinese ruler Shen Nong. And how was it invented? Student: By accident. Some leaves from a tea plant fell into the water he was boiling, and it produced a nice smell, so he tasted it. Teacher: Wonderful. Let's look at the details. Here are some key words: boil, remain, smell, taste. Can you explain how these words are related to the invention of tea? Student: Shen Nong was boiling drinking water. The leaves from the tea plant fell into the boiling water and remained there for some time. Then it produced a nice smell, and he tasted the brown water. Teacher: Very well - explained. Now, let's move on to paragraph 2. Show the cover of Cha Jing on the screen. Who can tell me something about Lu Yu and his book Cha Jing after reading this paragraph? Student: Lu Yu is called "the saint of tea". His book Cha Jing describes how tea plants were grown and used to make tea. It also discusses where the finest tea leaves were produced and what kinds of water were used. Teacher: Great. Let's fill in this chart together. For the name of the book, it's Cha Jing. The writer is Lu Yu. His position is "the saint of tea". And the book is about the growth and use of tea plants, as well as the origin of the finest tea leaves and the types of water used. Now, read paragraph 3 carefully and finish the mind map on the board about how tea spread. (Students read and start to fill in the mind map) Teacher: Let's check the mind map. When was tea brought to Korea and Japan? Students: During the 6th and 7th centuries. Teacher: And when did tea appear in England? Students: Around 1660. Teacher: Right. And the tea trade from China to Western countries took place in the 19th century. This helped to spread the popularity of tea and the tea plant to more places around the world. Now, let's do some thinking. Here are three questions for you to discuss in groups. First, why do you think tea became so popular around the world? Second, what other Chinese inventions have had a great impact on the world? Third, how can we promote Chinese culture like tea culture better? Discuss these questions in groups of four for five minutes. (Students start to discuss in groups) Teacher: Time's up. Which group would like to share your ideas? Group 1: We think tea became popular because it has a nice taste and many health benefits. Another Chinese invention that had a great impact is paper - making. To promote Chinese culture better, we can hold more cultural festivals abroad. Teacher: Very good ideas. Any other groups? Group 2: Tea is also popular because it's a symbol of Chinese culture. The compass is another important Chinese invention. We can use the Internet to promote Chinese culture, like making short videos about tea culture. Teacher: Excellent suggestions. Now, let's retell the knowledge about tea together. Use this circular mind map on the board as a guide. (Teacher and students retell the story of tea together) Teacher: According to the K - W - L - S chart we saw at the beginning, let's share what we have learned today. What did we know before class? We knew that tea is a very popular drink. What did we want to know? We wanted to know how it was invented. What have we learned? We learned that tea was invented by Shen Nong by accident nearly 5,000 years ago, about Lu Yu and his book Cha Jing, and how tea spread around the world. And what will we do? We will try to share this knowledge about tea culture with more people. Now, let's list the kinds of tea in China. Who can name some? Students: Green tea, black tea, oolong tea, pu - er tea... Teacher: Great. And now, for the last task, use the passive voice to write 5 sentences about tea. For example, "Tea plants are grown on the sides of mountains." Start writing in your notebooks. (Students start writing) Teacher: Let's check some of your sentences. Who would like to share? Student: Tea is picked by hand in many places. Teacher: Good. Another one? Student: Tea is drunk by millions of people around the world every day. Teacher: Excellent. Keep up the good work. That's all for today's class. Remember to review what we learned about tea and the passive voice. See you next time! 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 $$
