Unit 7 Global warming-E Writing This writing lesson is from Unit 7 "Global warming" of the 2024 Shanghai Foreign Language Education Press English textbook for Grade 7. The main task is to guide students to write an open letter about reducing our carbon footprint. It integrates the theme of global warming, aiming to make students not only understand the importance of taking climate action but also master how to express advice using "should" in English writing. The content is closely related to students' daily life, such as measures to reduce food waste, save energy at home and school, and choose green transportation, which helps students connect learning with real - world situations. 教学目标 1. Knowledge Objectives Students will be able to master the usage of the modal verb "should" to give advice, suggestions, or talk about obligations. For example, "We should turn off the lights when leaving the room." Students will be familiar with key vocabulary related to global warming and reducing carbon footprint, such as "carbon footprint", "reduce", "reuse", "greenhouse gas", "public transportation", etc. 2. Ability Objectives Students can write an open letter about reducing carbon footprint with clear structure, logical content, and correct grammar, using "should" appropriately to express their ideas. Students can improve their logical thinking ability by organizing ideas about how to take climate action. 3. Emotional Objectives Students will raise their awareness of environmental protection and understand their responsibilities in combating global warming. Students will be motivated to take actual actions to reduce their carbon footprint in daily life. 教学重难点 1. Teaching Key Points The correct usage of the modal verb "should" in giving advice. This includes the basic structure "Subject + should + base form of verb", using it in different person forms (I/we/he/she/they), and in conditional sentences and questions. How to give practical and diverse advice on reducing carbon footprint in an open letter, covering aspects such as food, clothing, home, school, and transportation. 2. Teaching Difficult Points Helping students avoid common mistakes when using "should", such as incorrect verb forms following "should" or inappropriate use in context. Guiding students to think deeply and comprehensively about climate actions, and expressing their ideas in a well - organized and fluent way in the open letter, rather than just listing simple and repetitive suggestions. 1. Modal Verb "Should" Basic Structure: Subject + should + base form of verb. For example, "You should study hard for the exam." Usage with Different Persons: First person (I/we): "I should exercise more to keep fit." "We should protect the environment." Third person (he/she/it/they): "He should wear a mask in public." "They should follow the school rules." In Conditional Sentences: "If I were you, I should start saving money now." In Questions: "Should we go to the park tomorrow?" 2. Key Vocabulary Global Warming - related: global warming, greenhouse gas, climate change, polar bear (as an example affected by global warming) Carbon Footprint - reducing: reduce, reuse, recycle, carbon footprint, public transportation, carpooling, bike, walk, energy - saving, food waste 教学过程 1. Lead - in (5 minutes) Show some pictures or short video clips about the consequences of global warming, such as melting icebergs, rising sea levels, and extreme weather. Ask students: "What are these phenomena? What causes them?" Lead students to review the knowledge of global warming learned before. Then ask: "Since global warming is such a serious problem, what can we do to help? Do you have any ideas?" Encourage students to share their initial thoughts briefly. 2. Knowledge Presentation (10 minutes) Explain the concept of "carbon footprint" to students: "A carbon footprint can tell us how much carbon and other greenhouse gases we release into the air because of human activities. Our daily behaviors have caused great harm to the earth. So, we need to take actions to reduce our carbon footprint." Teach the usage of the modal verb "should": Write the basic structure "Subject + should + base form of verb" on the blackboard and give several simple examples, like "You should drink more water." "We should keep our classroom clean." Let students practice making sentences with "should" in pairs. For example, one student says a subject, and the other makes a sentence with "should". Explain how to use "should" in conditional sentences and questions, and give examples: "If it rains, you should take an umbrella." "Should we plant more trees in our neighborhood?" 3. Model Analysis (10 minutes) Present a model open letter about reducing carbon footprint to students. Dear friends, Everyone can help reduce our carbon footprint by taking small steps at home and school. We should plan our meals every day to reduce food waste. We should take good care of our clothes and buy second - hand clothes. In addition, we can do a lot at home. For example, we should turn down the heating by one degree in winter. We can even help in the classroom by turning off the lights when we leave. We should also choose a green way to get around, like walking or taking a bus. Let’s take action now! Best regards, Wang Xin Analyze the structure of the letter with students: Introduction: Briefly introduce the topic of reducing carbon footprint. Body: List different ways to reduce carbon footprint, divided into aspects such as food, clothing, home, school, and transportation. Conclusion: Call on everyone to take action. Analyze the language use in the letter, especially how "should" is used to give advice. Let students underline the sentences with "should" and read them aloud. Then, ask students to complete a table about the advice in the letter, including aspects like food, clothing, home, school, and transportation. 4. Brainstorming and Group Discussion (10 minutes) Divide students into groups of 4 - 5. Let each group brainstorm more ways to reduce carbon footprint in daily life. They can consider aspects not mentioned in the model letter. Provide a table for each group to fill in, with columns of "Aspect" and "Advice". Each group discusses and fills in the table. Then, select one representative from each group to share their group's ideas with the whole class. 5. Writing Practice (10 minutes) Ask students to start writing their own open letters about reducing carbon footprint. They can use the ideas from the model letter, their group discussion, and their own thinking. Remind students to pay attention to the structure of the letter, the correct use of "should", and grammar. Walk around the classroom to provide individual guidance, answering students' questions and helping them with any difficulties they encounter during writing. 教学反思 Successes: The vivid lead - in with pictures and videos effectively attracted students' attention and quickly brought them into the topic of global warming, arousing their interest in learning. The step - by - step teaching of the usage of "should" and the analysis of the model letter made it easier for students to understand and follow. Most students could master the basic usage of "should" and had a clear idea about the structure of the open letter. The group discussion provided students with an opportunity to exchange ideas, which broadened their thinking. They came up with many creative and practical suggestions for reducing carbon footprint. Deficiencies: In the writing practice, some students still made mistakes in the use of "should", especially in complex sentence structures. This indicates that more practice on grammar in context is needed. A few students had difficulty in organizing their thoughts and expressing them fluently in writing. They might need more guidance on how to outline their writing before starting. Improvements: In future classes, design more grammar exercises specifically for the usage of "should" in different sentence patterns and contexts. Provide more writing templates or outlines at the beginning to help students with weak writing skills organize their ideas better. Also, increase the amount of reading materials related to environmental protection and carbon footprint reduction, so that students can accumulate more useful expressions and sentence patterns for writing. 2 / 37 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
