Unit 5 Grammar Focus教案 2025-2026学年外研版（2024）英语八年级上册

Unit 5 Play by the rules? 3rd Period: Grammar Focus I. Teaching Objectives (1) Language Ability · Master the usage of infinitives to express purpose: "to", "in order to", and "so as to". · Distinguish between the three structures and apply them correctly in sentences about following rules (e.g., "I speak quietly to not disturb others"). · Create context-based sentences using the target structures to describe actions taken for rule compliance. (2) Cultural Awareness · Understand that expressing purpose is a universal communication need, reflecting how people act intentionally to respect social norms. · Recognize that clear expression of purpose helps others understand rule-following behaviors across cultures. (3) Thinking Ability · Analyze how infinitives clarify the intention behind actions (e.g., "She waited in line to be fair" explains the motive for following the rule). · Classify sentences by identifying the purpose structure used ("to", "in order to", or "so as to"). (4) Learning Ability · Use grammar reference tools to self-correct errors in purpose expressions. · Collaborate in pairs to create meaningful sentences about rule-following using the target structures. II. Teaching Key Points · Structures: "to + verb" (e.g., "I study hard to pass the exam"), "in order to + verb" (e.g., "He whispered in order to not wake the baby"), "so as to + verb" (e.g., "We clean the classroom so as to keep it tidy"). · Negative forms: "in order not to" and "so as not to" (e.g., "She walked softly in order not to make noise"). · Skills: Using infinitives to express purpose in the context of rules. III. Teaching Difficult Points · Correctly using negative forms with "in order to" and "so as to" (avoiding "to not" in these structures). · Choosing the appropriate structure ("to", "in order to", or "so as to") based on formality and context. IV. Teaching Procedures (1) Lead-in: Review from "Rules" (5 mins) · Activity: Present sentences from the passage "Rules" and underline purpose expressions: 1. "I went to a quiet area in order to read." 1. "I covered my nose so as to reduce the smell." Ask: "Why did the author do these things? What words show his purpose?" · Design Intent: Connect grammar to the previous lesson’s text and introduce the focus on "purpose". (2) Presentation (10 mins) · Activity 1: Explaining Structures Introduce the three structures with examples related to rules: 1. "to + verb": Used for simple purposes (everyday contexts). e.g., "We follow traffic rules to stay safe." 1. "in order to + verb": Emphasizes purpose (slightly more formal). e.g., "Students raise hands in order to speak in class." 1. "so as to + verb": Similar to "in order to", often used in written or formal speech. e.g., "People recycle so as to protect the environment." · Activity 2: Negative Forms Highlight negative structures (only with "in order to" and "so as to"): e.g., "He turned off his phone in order not to disturb the meeting." e.g., "They walked slowly so as not to wake the baby." Note: "to not" is incorrect here (e.g., "He turned off his phone to not disturb" → wrong). (3) Practice (15 mins) · Activity 1: Fill in the Blanks Complete sentences with "to", "in order to", or "so as to": 1. We should queue ______ be fair to others. 1. She lowered her voice ______ not disturb the library users. 1. They clean the park ______ keep it beautiful. · Activity 2: Error Correction Fix mistakes in purpose expressions: 1. "He studied hard so as to not fail the test." → "He studied hard so as not to fail the test." (correct negative form) 1. "We wear uniforms in order to identifying as students." → "We wear uniforms in order to identify as students." (base verb after structure) (4) Production (10 mins) · Activity: Rule-Following Scenarios In pairs, create sentences about actions taken to follow rules, using all three structures. Example prompts: Sample dialogue: 1. At school: "We arrive on time..." 1. In public: "People throw trash in bins..." 1. A: "We arrive on time to start class early." 1. B: "Yes, and we listen carefully in order to understand the teacher." 1. A: "Students ask questions so as to clarify doubts." · Design Intent: Apply grammar in meaningful contexts related to rules. (5) Summary and Homework (5 mins) · Summary: Review key structures: "to", "in order to", "so as to" for purpose; negative forms with "in order not to" and "so as not to". · Homework: Write 5 sentences about rules at home/school, using each structure at least once (including one negative). · Design Intent: Reinforce grammar through personalized practice. V. Blackboard Design Infinitives for Purpose 1. Structures: - to + verb: "I follow rules to be polite." - in order to + verb: "He waits in line in order to be fair." - so as to + verb: "We cooperate so as to finish tasks." 2. Negative: - in order not to + verb - so as not to + verb *No "to not"!* VI. Homework Basic Homework 1. Match actions to their purposes using the target structures (e.g., "Close the door" → "to keep the room warm"). 1. Design Intent: Reinforce structure-meaning connections. Improving Homework 1. Write a short paragraph: "How I follow school rules" with 3 purpose expressions. 1. Design Intent: Apply grammar in a personal context. Expanding Homework 1. Find 2 examples of purpose expressions in English signs (e.g., "No smoking to protect health") and rewrite them using "in order to" or "so as to". 1. Design Intent: Connect classroom learning to real-world language. VII. Teaching Reflection · Check if students confused "to not" with "in order not to/so as not to". · Note difficulties in choosing between "in order to" and "so as to" (emphasize they are mostly interchangeable). · Evaluate if communicative activities helped students link grammar to rule-following contexts. 学科网（北京）股份有限公司 $
