Unit 3 Robots Grammar 教学设计 I. Teaching Objectives Enable students to master three grammar structures: using object clauses or objects + object complements, object clauses or question words + to - infinitives, and adverbial clauses or to - infinitives. Improve students’ ability to transform sentences using these grammar structures, enhancing accuracy in written expression for exam - related grammar tasks. Enhance students’ understanding of how to choose appropriate grammar forms to convey meaning clearly, which is crucial for effective communication and exam success. II. Language Knowledge 1. Key Grammar Structures Objects + Object Complements vs. Object Clauses: Replace object clauses with “objects + object complements” (e.g., “He saw that the robot was making breakfast.” → “He saw the robot making breakfast.”). Question Words + To - Infinitives vs. Object Clauses: Replace object clauses with “question words + to - infinitives” (e.g., “The robot no longer knew when it should cook breakfast.” → “The robot no longer knew when to cook breakfast.”). To - Infinitives vs. Adverbial Clauses: Replace adverbial clauses (expressing results or purposes) with “to - infinitives” (e.g., “Mr Jiang is always so busy that he does not have any time for hobbies.” → “Mr Jiang is always too busy to have any time for hobbies.”). 2. Key and Challenging Points Structure Transformation: Accurately transforming sentences between different grammar structures (clauses to phrases with to - infinitives, etc.). Contextual Application: Choosing the correct structure based on context to make sentences concise and clear. Exam - related Practice: Applying grammar knowledge to complete exercises similar to exam questions, such as sentence transformation and error correction. III. Teaching Procedures Step 1: Lead - in & Review (5 minutes) Show sentences with object clauses, adverbial clauses, and ask students to identify the structures. For example: “He found that his flat was in a complete mess.” (object clause); “Mr Jiang is always so busy that he does not have any time for hobbies.” (adverbial clause). Introduce the topic: “Today we’ll learn how to transform these clauses into simpler structures using to - infinitives and other forms, making our writing more concise.” Step 2: Presentation of Objects + Object Complements (A) (10 minutes) Structure Explanation: Use Section A to explain how to replace object clauses with “objects + object complements”. Highlight the pattern: “Subject + Verb + (that) clause” → “Subject + Verb + Object + Object Complement (doing/to do)”. Give examples: “He saw that the robot was making breakfast.” → “He saw the robot making breakfast.”; “He thinks that it is too much trouble to own a robot.” → “He thinks it too much trouble to own a robot.” Exercise Practice (Section A): Do “Talking about the robot” exercise. Students rewrite sentences using object clauses. Walk around to help with structure transformation. Check answers, e.g.: “Every day, I notice that the robot is busy with all kinds of housework.” “When I get up, I find that my breakfast is ready.” “When I come back from work, I find that my flat is as good as new.” “I consider that the robot is a great help in my daily life.” “I feel that it is comfortable to live with a robot.” Step 3: Presentation of Question Words + To - Infinitives (B) (12 minutes) Structure Explanation: Use Section B to explain replacing object clauses with “question words + to - infinitives”. Emphasize the pattern: “Subject + Verb + (wh - ) clause” → “Subject + Verb + wh - word + to - infinitive”. Give examples: “The robot no longer knew when it should cook breakfast.” → “The robot no longer knew when to cook breakfast.”; “Mr Jiang did not know what he should do with the robot.” → “Mr Jiang did not know what to do with the robot.” Exercise Practice (Section B): Do “Helping Mr Jiang look after his mother” exercise. Students rewrite sentences using “question words + to - infinitives”. Guide them to identify object clauses and transform them. Check answers, e.g., replacing “you should take your pills” with “when to take your pills”, etc. Step 4: Presentation of To - Infinitives vs. Adverbial Clauses (C) (10 minutes) Structure Explanation: Use Section C to explain replacing adverbial clauses (results/purposes) with “to - infinitives”. Highlight patterns: “so + adj./adv. + that (result)” → “too + adj./adv. + to - infinitive” or “adj./adv. enough + to - infinitive” “so that (purpose)” → “in order to/so as to” Give examples: “Mr Jiang is always so busy that he does not have any time for hobbies.” → “Mr Jiang is always too busy to have any time for hobbies.”; “The robot is so smart that it can do a lot of things for Mr Jiang.” → “The robot is smart enough to do a lot of things for Mr Jiang.” Exercise Practice (Section C): Do “The robot was great!” exercise. Students rewrite sentences using to - infinitives. Walk around to help with structure choice. Check answers, e.g.: “I was too forgetful to lock the door last night.” “The robot was careful enough to remind me of this.” “I was too weak to go up and down the stairs often.” “The robot was kind enough to buy me everything I needed.” “Sometimes I took a walk with it in order to have a better sleep.” Step 5: Comprehensive Practice & Exam Link (5 minutes) Mixed Structure Practice: Create sentences with mixed structures and ask students to transform them (e.g., object clause to object + complement, adverbial clause to to - infinitive). Have students write short paragraphs using these transformed structures to practice conciseness. Exam - style Questions: Show simple exam - like grammar questions (e.g., sentence transformation: “He is so young that he can’t go to school.” → “He is too young to go to school.”). Let students practice and explain transformation rules. Step 6: Summary & Homework (3 minutes) Summary (1 minute): Recap the three grammar structures: objects + complements, question words + to - infinitives, to - infinitives for adverbial clauses. Emphasize their functions in simplifying sentences. Homework (2 minutes): Ask students to find 5 sentences from previous reading materials (e.g., Unit 3 Reading) and transform them using these grammar structures. Prepare a short quiz for the next class to test peers on these grammar points. IV. Assessment of Teaching Effectiveness Formative Assessment: Observe students’ participation in exercise practices (A, B, C), checking for accurate structure transformation. Evaluate students’ sentence - making in comprehensive practice for conciseness and correctness. Summative Assessment (for later): Check homework transformations for accurate application of grammar structures. Use students’ self - made quizzes to assess peer understanding and mastery. V. Design Purpose Structure Mastery: Focuses on teaching key grammar transformations, essential for exam - related sentence - making and error - correction tasks. Conciseness in Writing: Encourages using simpler structures (to - infinitives) to make writing clearer, improving communication effectiveness. Progressive Practice: From explanation to exercise, helps students build confidence in applying complex grammar transformations. VI. Blackboard Design Unit 3 Robots Grammar — Sentence Transformations 1. Objects + Object Complements: Pattern: “Subject + Verb + (that) clause” → “Subject + Verb + Object + Complement (doing/to do)” Examples: “saw that... making” → “saw... making” 2. Question Words + To - Infinitives: Pattern: “Subject + Verb + (wh - ) clause” → “Subject + Verb + wh - word + to - infinitive” Examples: “knew when it should cook” → “knew when to cook” 3. To - Infinitives for Adverbial Clauses: Result: “so + adj. + that” → “too + adj. + to” / “adj. enough + to” Purpose: “so that” → “in order to” Examples: “so busy that” → “too busy to”; “so that he can” → “in order to have” Checklist: Transform accurately ✔️; Choose structure correctly ✔️; Apply in writing ✔️; Explain rules ✔️ 学科网（北京）股份有限公司 $$
