Unit 8 A green world Grammar 教学设计 I. Teaching Objectives 1. Knowledge Objectives Students will master the form and usage of the passive voice in the simple future tense (will be/be going to be + past participle). Students will be able to distinguish and apply the passive voice in future - related environmental - protection contexts. 2. Ability Objectives Improve grammar application skills by converting active to passive sentences and completing environmental - themed writing tasks. Enhance communication skills by using the passive voice in conversations about future environmental events. 3. Affective Objectives Strengthen awareness of future environmental actions and the role of language in describing them. Build confidence in using complex grammar structures to discuss green - life plans. II. Language Knowledge 1. Key Words & Phrases Passive voice structures: will be + past participle, be going to be + past participle Verbs: punish, recycle, organize, design, send, hold, throw, pollute, fill, hurt, harm, kill, show (past participles: punished, recycled, organized, designed, sent, held, thrown, polluted, filled, hurt, harmed, killed, shown) 2. Key Sentences “You will be punished if you cut down a tree.” “These bottles will be recycled to make new things.” “A show is going to be held at the town hall this Friday evening.” 3. Key and Challenging Points Key Points: Forming the passive voice in the simple future tense; understanding its use in future environmental scenarios. Challenging Points: Correctly applying the passive voice in complex sentences (e.g., with if clauses); choosing between will be and be going to be. III. Teaching Procedures (Total Duration: 45 Minutes) Step 1 Lead - in (6 Minutes) Show a future - environmental event picture (e.g., an upcoming environment show) and ask: “What will happen in this event? How can we describe it?” Introduce: “Today, we’ll learn the passive voice in the simple future tense—perfect for talking about future green actions!” Step 2 Form Explanation (12 Minutes) Structure Introduction (6 Minutes) Present the structure: Subject + will be/be going to be + past participle (+ by + doer). Example: “The environment show will be held at the town hall.” (focus on the event, not who holds it). Practice: Convert simple active future sentences to passive (e.g., “They will organize activities.” → “Activities will be organized by them.”). Usage Comparison (6 Minutes) Explain when to use will be (unplanned future) vs. be going to be (planned future). Example: “A show is going to be held” (planned) vs. “Rubbish will be thrown” (possible future action). Step 3 Practice Activities (15 Minutes) Part A: Environment Week Sentences (8 Minutes) Students use the passive voice to complete Part A’s Environment Week sentences (e.g., “A lot of activities in Environment Week are going to be organized.”). Walk around to check verb forms (e.g., “Posters will be designed by Sandy”, “Leaflets will be sent to all the people in the town”). Part B: Phone Conversation (7 Minutes) Students complete Part B’s phone conversation about the environment show with passive voice verbs (e.g., “The show is going to be held this Friday evening”). Discuss answers, emphasizing planned/unplanned uses of will be and be going to be. Step 4 Application: Pollution Article (8 Minutes) Students complete Part C’s pollution article using the passive voice (e.g., “Rubbish will be thrown into lakes and rivers”, “A show is going to be held at the town hall”). Peer - edit articles for correct passive voice usage and environmental - theme relevance. Step 5 Summary & Homework (4 Minutes) Summary (2 Minutes): Recap passive voice structures (future: will be/be going to be + pp) and usage in environmental contexts. Homework (2 Minutes): Write 3 sentences about future environmental actions in your city using the passive voice (2 will be, 1 be going to be). IV. Assessment of Teaching Effectiveness Check Part A and B answers for correct passive voice formation (verb forms, structure). Evaluate Part C articles for accurate passive voice use and coherence in describing pollution. Assess homework sentences for correct structure and relevance to environmental protection. V. Design Purpose Lead - in: Connect to future environmental events to show grammar relevance. Form Explanation: Clear structure breakdown with environmental examples for understanding. Practice: Apply grammar to unit - themed tasks (Environment Week, pollution) to reinforce learning. VI. Blackboard Design Unit 8 Grammar — Passive Voice (Simple Future) Structures: - Will be + past participle (unplanned future) (e.g., Rubbish will be thrown into rivers.) - Be going to be + past participle (planned future) (e.g., A show is going to be held at the town hall.) Key Verbs (Past Participles): recycle (recycled), organize (organized), design (designed) Homework: Write 3 future environmental passive sentences! VII. Teaching Reflection Strengths: Environmental - themed practice makes grammar relevant; step - by - step tasks build skills. Weaknesses: Some students may confuse will be and be going to be in complex contexts. Improvements: Add a “Future Action Sort” game: Give sentences, have students categorize by will be vs. be going to be for quick practice. 学科网（北京）股份有限公司 $$
