Last lesson, we talked about the environmental problems our world is facing and some ways to save it. Do you still remember what we discussed? S1: We talked about pollution from factories and cars. S2: We also said we should recycle things like glass and paper. T: Excellent! You have a good memory. Today, we're going to focus on three very important words that can help us protect the environment. Look at the screen, please. (Shows "reduce, reuse, recycle" on the screen) These are the three magic words. Can you read them? Ss: Reduce, reuse, recycle. T: Great! These three words are like a treasure for saving our world. Before we go deeper, let's watch a short video. It's about how these three words work in our daily lives. (Plays a 2-minute video showing people reducing plastic use, reusing bottles, and recycling paper) T: Wow, that was interesting, right? What did you see in the video? S3: I saw a girl using a cloth bag instead of a plastic bag when shopping. T: That's a good example of reducing plastic! What else? S4: A boy was using an old bottle to water the plants. T: Perfect! That's reusing. And the last part? S5: Some people were putting paper into a recycling bin. T: Exactly! That's recycling. Today, we'll learn all about these three words and how to apply them in our lives. Let's start our journey! Step 2: Vocabulary Building (5 minutes) T: First, let's learn some new words related to our topic. Look at the screen. The first word is "reduce". It means to make something smaller in size, amount, or degree. For example, we can reduce the amount of water we use. Read after me: reduce. Ss: Reduce. T: "Reuse" means to use something again instead of throwing it away. Like reusing a glass bottle as a pencil holder. Reuse. Ss: Reuse. T: "Recycle" we've mentioned before, but let's say it again. It means to process used materials so they can be used to make new things. Recycle. Ss: Recycle. T: Next word: "plastic". It's a light material made from chemicals, used to make many things like bags and bottles. Plastic. Ss: Plastic. T: "Material" refers to what something is made of, like wood, metal, or plastic. Material. Ss: Material. T: "Product" is something that is made to be sold. For example, a toy is a product. Product. Ss: Product. T: "Package" can be a noun or a verb. As a noun, it's the box, bag, etc., that something is sold in. As a verb, it means to put something in a box, bag, etc. Package. Ss: Package. T: "Bin" is a container for waste. We have different bins for different rubbish, like recycling bins. Bin. Ss: Bin. T: "Energy" is the power to do work, like electricity or heat. We need to save energy. Energy. Ss: Energy. T: Now, let's play a quick game. I'll show a picture, and you have to say which word it matches: reduce, reuse, or recycle. Ready? (Shows a picture of turning off the lights when leaving a room) S6: Reduce! Because it reduces energy use. T: Correct! (Shows a picture of using a broken cup as a plant pot) S7: Reuse! T: Well done! (Shows a picture of a truck taking old newspapers to a factory to make new paper) S8: Recycle! T: Perfect! You're getting the hang of it. Let's move on. Step 3: Pre-reading (5 minutes) T: Now, let's look at the title of our passage today: "Repeat these three words daily: reduce, reuse and recycle." What do you think the passage will talk about? S9: It will explain what reduce, reuse, and recycle mean. S10: It might tell us how to do these three things. T: Good guesses! Let's look at the pictures in the passage. (Points to the pictures in the textbook) The first picture shows a person carrying a cloth bag. The second one is someone mending a shirt. The third is a recycling bin with different materials. Can you connect them to our three words? S11: The cloth bag is reduce because it reduces plastic bags. S12: Mending a shirt is reuse because you use it again instead of buying a new one. S13: The recycling bin is for recycling. T: Brilliant! Now, let's read the passage and check if your ideas are correct. But before that, let's think about these questions: Why are these three words important? What can happen if we follow them? Keep these in mind as you read. Step 4: Reading (5 minutes) T: Now, read the passage silently. While reading, underline the sentences that explain reduce, reuse, and recycle. You have 5 minutes. (Students read silently) T: Time's up. Let's find the part about "reduce". Who can read that sentence? S14: "Reduce means using less. For example, turn off the lights when you leave a room. This reduces the amount of energy you use." T: Excellent! What's an example of reducing in the passage? Ss: Turning off the lights when leaving a room. T: Correct. What else can we reduce in our daily lives? S15: We can reduce the use of plastic bottles by using a reusable one. T: Great idea! Now, let's find the part about "reuse". Who wants to read that? S16: "Reuse means using things again. For example, if you have a glass bottle, don't throw it away. You can clean it and use it again for water." T: Good. The example here is reusing a glass bottle. Can you think of another example of reusing? S17: We can reuse old jars to store food. T: Perfect! Now, the last one: "recycle". Who can read that? S18: "Recycle means changing old things into new things. For example, old newspapers can be recycled to make new paper." T: Well done. The example is recycling old newspapers. What other things can we recycle? S19: We can recycle plastic bottles and metal cans. T: Exactly! Now, let's read the passage together. One, two, three, start! (Students read the passage aloud) T: Great reading! Now, let's answer some questions. Question 1: What does "reduce" mean? S20: It means using less. T: Correct. Question 2: How can we reuse a glass bottle? S21: We can clean it and use it again for water. T: Good. Question 3: What can old newspapers be recycled into? S22: New paper. T: Perfect! You all understand the passage well. Step 5: Language Points (5 minutes) T: Now, let's look at some important language points in the passage. The first one is "instead of". It means in place of someone or something. For example, "She used a cloth bag instead of a plastic bag." Here, "instead of" is followed by a noun. It can also be followed by a gerund. "He walked to school instead of taking the bus." Let's make a sentence with "instead of". S23: I drink tea instead of coffee. T: Good! Another example: "We should reuse things instead of throwing them away." T: Next, "so that". It is used to express purpose, meaning "in order to". For example, "Turn off the lights so that we can save energy." Let's see another sentence: "She saves money so that she can buy a bike." Can you make a sentence with "so that"? S24: I study hard so that I can get good grades. T: Excellent! Now, "It's + adj. + to do sth." This structure is used to say that doing something has a certain quality. For example, "It's important to recycle." "It's easy to reuse a bottle." Let's practice. What's something easy to do for the environment? S25: It's easy to turn off the tap when brushing teeth. T: Correct. What's something important to do? S26: It's important to reduce plastic use. T: Great! Another point: "by + doing sth." This shows the way of doing something. For example, "We can save water by fixing a dripping tap." "They keep warm by wearing thick clothes." Let's make a sentence. How can we reduce waste? S27: We can reduce waste by buying only what we need. T: Perfect! You're mastering these points. Let's do a quick exercise. Fill in the blanks with the correct words: instead of, so that, by. (Shows sentences on the screen) We should walk to school _______ taking a car. Save water _______ we can have enough for the future. We can reuse things _______ cleaning them. T: Who wants to try the first one? S28: Instead of. T: Correct. Second one? S29: So that. T: Good. Third one? S30: By. T: Excellent! Well done, everyone. Step 6: Speaking Practice (5 minutes) T: Now, let's have a role-play. I'll divide you into pairs. One of you is a reporter, and the other is an environmental expert. The reporter will ask the expert about reduce, reuse, and recycle. The expert needs to explain each word and give examples. Here's a sample dialogue. (Shows sample on the screen) Reporter: What does "reduce" mean, expert? Expert: It means using less. For example, we can reduce electricity use by turning off the TV when no one is watching. Reporter: That's helpful. What about "reuse"? ... T: You have 5 minutes to prepare your dialogue. Then, some pairs will perform in front of the class. Let's start! (Students practice in pairs) T: Time's up. Which pair wants to perform first? ( Pair 1 comes to the front ) Reporter (S31): What does "reduce" mean, expert? Expert (S32): It means using less. For example, we can reduce plastic by using a reusable water bottle instead of buying bottled water. Reporter: Good idea. What is "reuse"? Expert: Reuse is using things again. Like reusing a shoebox to store toys. Reporter: That's clever. And "recycle"? Expert: It's changing old things into new ones. For example, recycling plastic bottles to make new bags. Reporter: Thank you for your advice, expert. Expert: You're welcome. T: Wonderful! That was a great dialogue. Your examples are very practical. Any other pairs? ( Pair 2 performs ) ... T: Excellent work, everyone! You all understand how to explain these three words clearly. Step 7: Group Project (5 minutes) T: Now, let's work in groups of five. Your task is to make a poster about "reduce, reuse, recycle". Each group will have a section for each word. You need to write the meaning, draw a picture, and list three examples for each. Let's see which group can make the most creative poster. You have 10 minutes. Let's start! (Students work in groups, teacher walks around to help) T: Time's up. Let's present our posters one by one. Group 1, please. ( Group 1 shows their poster ) S33: This is our poster. For "reduce", the meaning is using less. Our examples are: reduce water by taking shorter showers, reduce plastic by not using straws, reduce food waste by eating all the food on the plate. The picture is a shower with a timer. S34: For "reuse", meaning is using again. Examples: reuse old clothes as rags, reuse envelopes by covering the old address, reuse a cup instead of using disposable ones. The picture is an old shirt being used as a rag. S35: For "recycle", meaning is changing old things into new. Examples: recycle aluminum cans, recycle glass jars, recycle cardboard boxes. The picture is a recycling bin with different materials. T: Wow, that's a fantastic poster! The examples are very detailed, and the pictures are clear. Well done! Group 2, your turn. ... T: All groups did a wonderful job! Your posters are informative and creative. I'll put them on the classroom wall so everyone can learn from them. Step 8: Writing Task (5 minutes) T: Now, let's do a short writing task. Write a paragraph about what you will do to follow "reduce, reuse, recycle" in your daily life. You need to include at least one example for each word. You have 7 minutes. Let's start! (Students write) T: Time's up. Who wants to read their paragraph? S36: I will reduce by turning off the lights when I leave my room. I will reuse my old backpack instead of buying a new one. I will recycle all my old notebooks by putting them in the recycling bin. I hope these actions can help save the world. T: That's a great paragraph! Your examples are clear and realistic. Anyone else? S37: I plan to reduce plastic by bringing my own bag to the supermarket. I will reuse my water bottle every day. I will recycle my family's newspapers. It's easy to do these things, and I think they can make a difference. T: Excellent! You have a good plan. Remember, even small actions can help protect our environment. Step 9: Summary and Homework (5 minutes) T: Let's summarize what we learned today. What are the three important words? Ss: Reduce, reuse, recycle! T: What does "reduce" mean? Ss: Using less! T: "Reuse"? Ss: Using things again! T: "Recycle"? Ss: Changing old things into new things! T: Perfect! You all did a great job today. For homework, please: 1. Write a 100-word essay about the importance of reduce, reuse, and recycle. 2. Keep a diary for three days, writing down one thing you did each day for each of the three words. For example, Day 1: reduce - turned off the tap; reuse - used an old box; recycle - put a can in the recycling bin. 3. Prepare a short presentation for next class about your diary. T: Remember, our world needs us. Let's repeat these three words every day and act on them: reduce, reuse, recycle! Class is over. Goodbye! 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 $$
