Apply language comprehensively to create coherent eco-related outputs (e.g., posters, debates) (key); balancing accuracy and fluency in complex communication (difficult). 【教学过程】 Step 1: Warm-up and Review Overview T: Good morning, everyone! Today, we're going to have a revision class for Module 12 "Save our world" and Revision module B. Let's start by looking back at what we've learned in Module 12. Who can tell me the main topic of this module? S1: It's about protecting the environment and saving our world. T: Exactly! And what are the three key words we focused on in Unit 2? S2: Reduce, reuse and recycle. T: Well said! We also learned some important grammar points, like conditional sentences with "if", and useful expressions such as "instead of", "so that" and "by + doing sth". Today, we'll review all these and practice using them in different contexts. Let's start with a quick game. I'll show you some pictures, and you need to say which word or expression it relates to. (Shows a picture of someone turning off the tap) S3: Reduce, because it's reducing water use. T: Correct! (Shows a picture of using an old bottle as a pencil holder) S4: Reuse. T: Good. (Shows a picture of putting paper into a recycling bin) S5: Recycle. T: Perfect! (Shows a picture of a cloth bag instead of a plastic bag) S6: Instead of. T: Excellent! You're all off to a great start. Step 2: Grammar Review - Conditional Sentences T: Let's focus on conditional sentences first. Remember the structure? It's "If + present simple, will + base verb". What does this structure talk about? S7: It talks about possible future situations and their results. T: Exactly! Let's practice making more sentences. I'll give you a condition, and you tell me the result. "If we cut down too many trees..." S8: If we cut down too many trees, many animals will lose their homes. T: Good. "If we use too many plastic bags..." S9: If we use too many plastic bags, the environment will be polluted. T: Great. Now, let's do it the other way. I'll give you the result, and you provide the condition. "We will have more clean water..." S10: If we stop polluting the rivers, we will have more clean water. T: Correct. "The air will be fresher..." S11: If we drive fewer cars, the air will be fresher. T: Excellent! Now, let's do some exercises. Look at the screen. (Shows sentences: 1. If we ______ (not protect) wild animals, they ______ (die out). 2. If people ______ (recycle) more, there ______ (be) less waste. 3. If students ______ (plant) more trees, our school ______ (become) greener.) T: Who wants to try the first one? S12: If we don't protect wild animals, they will die out. T: Correct. Second one? S13: If people recycle more, there will be less waste. T: Good. Third one? S14: If students plant more trees, our school will become greener. T: Perfect! You all remember how to use this structure well. Step 3: Vocabulary Review T: Now, let's review some key vocabulary from Module 12. I'll say a definition, and you guess the word. The first one: To make something smaller in amount or degree. S15: Reduce. T: Correct. To use something again instead of throwing it away. S16: Reuse. T: Good. To process used materials so they can be used to make new things. S17: Recycle. T: Well done. A place where things are made, often causing pollution. S18: Factory. T: Right. To make the air, water, etc. dirty. S19: Pollute. T: Excellent. A container for waste. S20: Bin. T: Correct. Now, let's do a matching exercise. Match the words with their opposites. (Shows words: reduce, reuse, pollute, waste, save; opposites: throw away, destroy, increase, protect, clean) T: Who wants to match "reduce"? S21: Increase. T: Correct. "Reuse"? S22: Throw away. T: Good. "Pollute"? S23: Clean. T: Right. "Waste"? S24: Save. T: Correct. "Destroy"? S25: Protect. T: Perfect! You have a good command of these words. Step 4: Practice with Expressions T: We also learned some useful expressions: "instead of", "so that" and "by + doing sth". Let's review how to use them. "Instead of" is used to say that one thing is done rather than another. For example, "She walked instead of taking a bus." "So that" is used to show purpose, like "He studies hard so that he can pass the exam." "By + doing sth" shows the way of doing something, such as "We can learn English by speaking it every day." Now, let's fill in the blanks with the correct expression. (Shows sentences: 1. We can reduce waste ______ buying only what we need. 2. He takes a bike to school ______ taking a car. 3. Save energy ______ we can reduce pollution. 4. We can protect animals ______ not cutting down their habitats. 5. She saves money ______ she can buy a new book.) T: First sentence: "We can reduce waste ______ buying only what we need." S26: By. T: Correct. Second: "He takes a bike to school ______ taking a car." S27: Instead of. T: Good. Third: "Save energy ______ we can reduce pollution." S28: So that. T: Right. Fourth: "We can protect animals ______ not cutting down their habitats." S29: By. T: Correct. Fifth: "She saves money ______ she can buy a new book." S30: So that. T: Excellent! You all know how to use these expressions correctly. Step 5: Speaking - Group Discussion T: Now, let's have a group discussion. Work in groups of four. The topic is "What can we do as students to protect the environment in our school and community?" Use the vocabulary, grammar and expressions we've reviewed. Each group needs to come up with at least five ideas. You have 8 minutes to discuss. Then, each group will present your ideas. Let's start. (Students discuss in groups) T: Time's up. Which group wants to present first? Group 1 representative: We can start a recycling program in our school so that we can recycle paper, plastic and glass. We can reduce the use of paper by using electronic devices instead of notebooks. We can reuse old textbooks by passing them to younger students. We can plant trees in our community by organizing a tree-planting day. We can also make posters to tell people about protecting the environment so that more people will join in. T: Great ideas! You used "so that", "instead of" and "by + doing sth". Group 2? Group 2 representative: We can save electricity by turning off the lights and computers when not in use. We can reduce plastic waste by bringing our own water bottles instead of buying bottled water. We can clean up the park in our community so that it will be a beautiful place. If we see someone littering, we can tell them to put rubbish in the bin. We can also start a club to discuss environmental problems and find solutions. T: Excellent! You used many of the language points we reviewed. Well done. Step 6: Reading Comprehension T: Now, let's do a reading comprehension exercise from Revision module B. It's a passage about environmental protection. Read the passage silently and answer the questions. (Shows passage and questions on the screen) Passage: "Our world is facing many environmental problems. Pollution from factories and cars is making the air dirty. Many rivers and oceans are polluted with waste. We need to take action to protect our environment. We can reduce the amount of energy we use by turning off lights and appliances when not in use. We can reuse things like bottles and bags instead of throwing them away. We can also recycle paper, plastic and metal. If everyone does these small things, our world will be a better place for future generations." Questions: 1. What is making the air dirty? 2. What is polluting rivers and oceans? 3. How can we reduce energy use? 4. What can we reuse? 5. What will happen if everyone takes action? T: You have 5 minutes to read and answer. (Students read and answer) T: Time's up. Let's check the answers. Question 1: What is making the air dirty? S31: Pollution from factories and cars. T: Correct. Question 2: What is polluting rivers and oceans? S32: Waste. T: Good. Question 3: How can we reduce energy use? S33: By turning off lights and appliances when not in use. T: Right. Question 4: What can we reuse? S34: Bottles and bags. T: Correct. Question 5: What will happen if everyone takes action? S35: Our world will be a better place for future generations. T: Perfect! You all understood the passage well. Step 7: Writing - A Letter T: Now, let's practice writing. Write a letter to your friend telling them about what you are doing to protect the environment and encouraging them to join you. Use at least two conditional sentences, and some of the expressions: "instead of", "so that", "by + doing sth". You have 10 minutes to write. Then, some of you can read your letters. (Students write) T: Time's up. Who wants to read their letter? S36: Dear Tom, I'm writing to tell you about what I'm doing to protect the environment. I reduce plastic use by bringing my own bag when shopping instead of using plastic bags. I also reuse old jars to store my stationery. If we all do these things, our environment will be better. I hope you can join me so that we can make a difference together. Best wishes, [Name] T: That's a great letter! You used conditional sentence, "by + doing sth", "instead of" and "so that". Well done. Another one? S37: Dear Mary, I want to share with you how I'm protecting the environment. I save water by taking short showers. I recycle paper so that we can save trees. If you start doing these things too, we can protect our world together. You can also reuse your old clothes by giving them to charity instead of throwing them away. Let's do it! Your friend, [Name] T: Excellent! Your letter is clear and uses the language points effectively. Step 8: Listening Practice T: Now, let's do a listening practice. Listen to a talk about environmental protection and answer the questions. (Shows questions: 1. What is the main idea of the talk? 2. What does the speaker suggest reducing? 3. How does the speaker say we can reuse things? 4. What will happen if we recycle, according to the speaker? 5. What does the speaker encourage people to do?) T: Are you ready? Let's listen. (Plays the recording) T: Let's listen again. (Plays the recording again) T: Now, let's answer the questions. Question 1: What is the main idea of the talk? S38: It's about how to protect the environment by reducing, reusing and recycling. T: Correct. Question 2: What does the speaker suggest reducing? S39: The use of plastic and energy. T: Good. Question 3: How does the speaker say we can reuse things? S40: By using old clothes as rags and old bottles as planters. T: Right. Question 4: What will happen if we recycle, according to the speaker? S41: We will save natural resources. T: Correct. Question 5: What does the speaker encourage people to do? S42: To start protecting the environment today. T: Perfect! You all listened carefully. Step 9: Role-play T: Now, let's do a role-play. Work in pairs. One of you is a reporter interviewing an environmentalist about protecting the environment. Use the language points we've reviewed. You can ask questions about reduce, reuse, recycle, and what will happen if we take action. Here's a sample: Reporter: What is the most important thing we can do to protect the environment? Environmentalist: I think reducing our use of resources is very important. If we reduce, we will produce less waste. You have 7 minutes to prepare. Then, some pairs will perform. (Students prepare) T: Time's up. Which pair wants to perform? Pair 1: S43 (Reporter): What can people do to reduce waste at home? S44 (Environmentalist): They can reduce waste by buying only what they need. They can also use cloth napkins instead of paper ones. Reporter: How can we reuse things in our daily lives? Environmentalist: We can reuse old boxes to store things. If we reuse more, we will save money. Reporter: What will happen if everyone recycles? Environmentalist: If everyone recycles, we will save a lot of natural resources. It's important to start early so that future generations can have a good environment. T: Excellent role-play! You used many of the language points we reviewed. Another pair? Pair 2: S45 (Reporter): What is the biggest environmental problem we face? S46 (Environmentalist): I think pollution is a big problem. Factories and cars pollute the air and water. Reporter: How can we reduce air pollution? Environmentalist: We can reduce air pollution by taking public transport instead of driving. So that the air will be cleaner. Reporter: What advice do you have for students? Environmentalist: Students can start small. For example, recycle paper at school. If every student does this, it will make a big difference. T: Great job! You had a meaningful conversation about environmental protection. Step 10: Summary and Homework T: Let's summarize what we reviewed today. We went over the key vocabulary: reduce, reuse, recycle, pollute, factory, etc. We practiced conditional sentences with "if", and expressions like "instead of", "so that" and "by + doing sth". We also did speaking, reading, writing and listening activities to use these language points. T: For homework: 1. Write a 150-word passage about "The Importance of Protecting the Environment", using at least three conditional sentences and two expressions from today's review. 2. Make a poster about environmental protection, using the key words and ideas we discussed. 3. Review all the language points from Module 12 and Revision module B for a small quiz next class. T: Remember, protecting the environment is not just a lesson in a book, but something we should do every day. Let's keep working together to save our world. Class is over. Goodbye!
