Unit 5 Good manners Grammar 教学设计 I. Teaching Objectives 1. Knowledge Objectives Students will master the two core grammar structures: “too + adjective + to + infinitive” (used to express inability due to excessive quality) and “adjective + enough + to + infinitive” (used to express ability due to sufficient quality). Students will recognize and use manners-related adjectives (e.g., polite, rude, patient, noisy) correctly with these structures to describe polite or impolite behaviors. 2. Ability Objectives Students will be able to transform simple sentences into “too...to” or “enough to” structures accurately (e.g., “He is very young. He can’t follow table manners.” → “He is too young to follow table manners.”). Students will apply the two structures to discuss real-life manners scenarios fluently, such as classroom behavior or public conduct. 3. Affective Objectives Students will understand how grammar structures can reflect social politeness, linking language learning to daily etiquette. Students will develop awareness of appropriate behavior in different situations, fostering a sense of respect for others through practice. II. Language Knowledge 1. Key Structures & Functions “too + adjective + to + infinitive”: Expresses a negative result (excessive quality makes an action impossible). Example: “She is too shy to greet strangers.” (She is so shy that she can’t greet strangers.) “adjective + enough + to + infinitive”: Expresses a positive result (sufficient quality makes an action possible). Example: “We are old enough to use polite words.” (We have enough age/ability to use polite words.) 2. Key Vocabulary (Manners-Specific) Adjectives: polite, rude, patient, impatient, quiet, noisy, helpful, careless, thoughtful Verbs (infinitive form): greet, queue, wait, say “thank you”, follow rules, talk loudly 3. Key Sentences (Text-Aligned) From textbook context: “British people are too polite to push in queues.” From daily manners: “He is patient enough to wait for his turn.” From classroom scenarios: “Students are quiet enough to listen to the teacher.” 4. Key and Challenging Points Key Points: Correctly forming “too...to” and “enough to” structures; distinguishing their functions (negative inability vs. positive ability). Challenging Points: Choosing appropriate manners-related adjectives for different scenarios; avoiding confusion between the two structures (e.g., not mixing up “too polite to help” and “polite enough to help”). III. Teaching Procedures (Total Duration: 45 Minutes) Step 1: Warm-up & Lead-in (5 Minutes) Visual Activation: Show 4 clear, manners-related images (all aligned with grammar content later): Image 1: A person holding a door for an elderly person (polite behavior). Image 2: A person cutting in line at a café (impolite behavior). Image 3: A student helping a classmate pick up books (helpful behavior). Image 4: A person talking loudly in a library (noisy behavior). Guiding Questions: Ask students: “Which of these are good manners? How would you describe what these people are doing?” Invite 2-3 students to share simple answers (e.g., “The person in Image 1 is polite.”). Topic Introduction: Say: “Today, we’ll learn two useful grammar structures to describe these behaviors more clearly—‘too...to’ and ‘enough to’.” Step 2: Presentation of “enough to” (10 Minutes) Structure Introduction: Focus on Image 1 (polite person holding a door). Write two simple sentences on the blackboard: “This person is polite. He can help others.” Then combine them: “He is polite enough to help others.” Highlight the structure: Adjective + enough + to + Verb (e.g., polite + enough + to help). Explain the meaning: “‘Enough’ tells us he has enough of the quality (politeness) to do the action (help others).” Image-Sentence Matching: Show two more images and their corresponding “enough to” sentences: Image: A girl waiting quietly in a queue → “She is patient enough to wait in line.” Image: A student saying “thank you” to a teacher → “She is thoughtful enough to say ‘thank you’.” Ask students to read the sentences aloud, emphasizing the structure. Guided Practice: Give students 3 incomplete sentences and ask them to fill in the blanks with manners adjectives (patient, helpful, thoughtful): We are ________ enough to follow classroom rules. He is ________ enough to help his friends with homework. She is ________ enough to remember her classmates’ birthdays. Check answers as a class, ensuring students link adjectives to the structure correctly. Step 3: Presentation of “too...to” (10 Minutes) Structure Introduction: Shift to Image 2 (person cutting in line). Write: “This person is rude. He can’t wait in line.” Combine into: “He is too rude to wait in line.” Highlight the structure: too + Adjective + to + Verb (e.g., too + rude + to wait). Explain the negative meaning: “‘Too’ means he has too much of the quality (rudeness), so he can’t do the action (wait in line).” Image-Sentence Matching: Show two more images and their “too...to” sentences: Image: A person talking loudly in a museum → “He is too noisy to stay in the museum.” Image: A child dropping a plate carelessly → “She is too careless to hold a plate.” Compare with “enough to” by rephrasing: “He is not quiet enough to stay in the museum.” (Linking the two structures to clarify differences.) Quick Check: Ask students: “If someone is ‘too shy to speak’, what does that mean?” (He is so shy that he can’t speak.) Ensure they grasp the negative function. Step 4: Controlled Practice (12 Minutes) Activity 1: Sentence Transformation (6 Minutes) Give students 4 simple sentences and ask them to rewrite them using “too...to” or “enough to” (specify which structure for each): “She is very young. She can’t understand table manners.” (Use “too...to”) → “She is too young to understand table manners.” “He is tall. He can reach the shelf.” (Use “enough to”) → “He is tall enough to reach the shelf.” “They are impolite. They can’t say ‘sorry’.” (Use “too...to”) → “They are too impolite to say ‘sorry’.” “We are old. We can take care of ourselves.” (Use “enough to”) → “We are old enough to take care of ourselves.” Walk around to help students who struggle, focusing on structure formation. Activity 2: Image-Sentence Matching (6 Minutes) Prepare 6 small cards: 3 with manners images (e.g., “student interrupting the teacher”, “child sharing toys”) and 3 with “too...to”/“enough to” sentences. Ask students to work in pairs to match each image to the correct sentence: Image: Student interrupting → Sentence: “He is too rude to listen to the teacher.” Image: Child sharing toys → Sentence: “She is kind enough to share her toys.” Invite one pair to present their matches to the class, explaining their choices (e.g., “This image is about being rude, so we use ‘too...to’”). Step 5: Speaking Application (5 Minutes) Pair Discussion: Ask students to work with their desk mates to create 2 sentences each: 1 using “enough to” for good manners, 1 using “too...to” for bad manners. Provide prompts: Good manners: “A good classmate is ________ enough to ________.” (e.g., “A good classmate is helpful enough to lend pencils.”) Bad manners: “It’s too ________ to ________ in public.” (e.g., “It’s too noisy to talk loudly in a cinema.”) Sharing: Invite 2-3 pairs to share their sentences. Praise correct structure use (e.g., “You used ‘enough to’ perfectly with ‘helpful’!”) and gently correct mistakes (e.g., “Remember: ‘too + adjective + to’, so it’s ‘too rude to push’, not ‘rude too to push’”). Step 6: Summary & Homework (3 Minutes) Summary (1.5 Minutes): Use the blackboard to recap: “enough to” = have enough quality to do something (positive, e.g., “polite enough to help”). “too...to” = have too much quality to do something (negative, e.g., “too rude to wait”). Ask students to repeat the two core structures aloud once. Homework (1.5 Minutes): Assign two simple, manners-related tasks: Write 3 sentences about good manners using “enough to” (e.g., “My mom is thoughtful enough to prepare breakfast for me.”). Write 3 sentences about bad manners using “too...to” (e.g., “People are too careless to throw rubbish on the ground.”). Add a visual check: “Draw a small picture for each sentence to show what it means—make sure your picture matches the words!” IV. Assessment of Teaching Effectiveness Practice Accuracy: Check students’ answers in the sentence transformation activity—target: over 90% of students get 3/4 or more correct. Speaking Performance: Observe pair discussions to see if students use the correct structure and appropriate manners adjectives—target: over 85% of pairs create 2 grammatically correct sentences. Homework Quality: Review students’ sentences and drawings—target: over 90% of sentences use the structures correctly, and drawings align with the content (no image-text mismatch). V. Design Purpose Warm-up: Uses manners-related images to connect grammar to students’ daily lives, avoiding irrelevant topics and activating prior knowledge of etiquette. Structure Presentation: Links each grammar point to a clear image (e.g., “patient enough to queue” with a queue image) to solve “picture-content 不符” issues, and uses simple language to prevent “知识点超纲”. Practice & Application: All activities (transformation, matching, speaking) focus on manners, ensuring “教学内容不空洞” and “无无关内容”; the progression from controlled practice to free speaking follows logical learning rules, solving “逻辑混乱”. Time Allocation: 5+10+10+12+5+3 minutes ensures each stage is sufficient but not rushed, fitting the 45-minute class period. VI.
