译林新版8BU4 Lesson Plan 3: Grammar Theme: Making Decisions and Following Rules Textbook Reference: Unit 4, Pages 52-53 I. Teaching Objectives Language Ability: Master the structure "Question Word + To-Infinitive" as objects; distinguish between must/have to (necessity) and must not/don't have to (prohibition/lack of necessity). Thinking Quality: Deduce grammar rules from examples; analyze context to choose the correct modal verb (subjective vs. objective necessity). Learning Ability: Summarize grammar rules in a chart; self-correct errors in sentence construction. II. Key & Difficult Points Key: Structure: Verb/Adj + Wh-word + to do; Usage of must vs. have to. Difficult: Understanding why why cannot be used with to-infinitive; distinguishing mustn't (forbidden) from don't have to (not necessary). III. Teaching Procedures Step 1: Lead-in Scenario: Planning a "Reading Month" event. Sentences: "We need to decide what to read." "I don't know where to find the books." Q1: "Can we say 'I don't know what do I read'? Or 'I don't know what to read'? Which sounds smoother?" Step 2: Rule Discovery Activity: Analyze examples in Part A. 1 decide what to read 2 know how to write 3 ask where to find Rule Formulation: Structure: Verb (know, decide, ask...) / Adj (sure, clear) + Wh-word (what, where, how, who, when) + to + verb. Exception Alert: Q2: "Look at the note. Can we use 'why' here? Why not?" (Explain: Why implies reason, usually needs a full clause). Practice (Part A1 & A2): Fill in the blanks with correct Wh-words. Step 3: Comparison (Must vs. Have to) Context: Library Rules (Part B). Analysis: 1 "You must be quiet." (Speaker's rule/strong obligation). 2 "You have to show your ID." (External rule/situation). 3 "You must not eat." (Prohibition). 4 "You don't have to stay." (No necessity/Optional). Q3: "If I say 'You don't have to come', can you come if you want? If I say 'You mustn't come', can you come?" . 1 It is necessary to hand in homework. -> You have to hand in... 2 It is forbidden to run. -> You must not run. Step 4: Comprehensive Practice Task 1: Word Fill-in. Provide a paragraph about school rules with missing modals and wh-structures. Task 2: Short Passage Fill-in. Example: "Our teacher told us (1)_ (when/meet). We (2)_ (must) be late. But we (3)_ (not have to) bring laptops if we don't want to." Game: "Rule Maker." Groups create 3 rules for a "Dream School" using must/mustn't/don't have to and present using wh-to structures ("We decided where to have lunch..."). IV. Homework Complete the workbook exercises on pages 131-132. Write 5 sentences about your weekend plan using "wh-word + to-infinitive" and 5 sentences about house rules using modals. V.
