教学环节
Step 1 Warm-up & Review
1. Quick Response: Teacher states a health problem (e.g., "I have a bad cough"), students rapidly respond with advice using "You should...".
2. Picture Guessing: Display images of people looking unwell. Ask: "What’s the matter with him/her " Students answer using full sentences: "He/She has a..." or "He/She feels...".
3. Brainstorming: Set a timer for 1 minute. Students list as many health problems and corresponding advice phrases as possible on the blackboard.
Step 2 Grammar Discovery (Task 1: Find the Rules)
1. Observation: Students read the sentences in Grammar Focus. Underline the verbs immediately following should/shouldn’t.
2. Discussion: Work in pairs to discuss:
- What form of verb follows should
- How do we form negative sentences
- How do we ask questions using should
3. Summary: Teacher guides students to summarize the rules:
- Structure: Subject + should/shouldn’t + verb (base form).
- Question: Should + subject + verb (base form)...
- Usage: Used for giving advice or making suggestions.
Step 3 Practice & Consolidation (Task 2: Apply the Rules)
1. Fill in the Blanks (3a): Complete the conversation by choosing should or shouldn’t and putting the verb in the correct form. Check answers collectively.
2. Matching (3b): Match the health problems with the appropriate advice. Then, practice orally: "If you have a..., you should..."
3. Sentence Making: Provide scenarios (e.g., "It's raining heavily", "You have a big test tomorrow"), students create advice sentences using should/shouldn’t.
Step 4 Production (Task 3: Create & Share)
1. Group Work (3c): Role-play scenario: "The School Clinic". One student acts as the patient describing a problem, others act as doctors/nurses giving advice.
- Patient: "I feel... / I have a..."
- Doctors: "You should...", "You shouldn’t...", "Why don’t you... "
2. Role-play Performance: Invite selected groups to perform their dialogues. The class evaluates based on accuracy, fluency, and creativity.
3. Writing Task: Write a short paragraph (3-5 sentences) giving advice to a friend who is always tired. Must include at least two should sentences and one shouldn’t sentence.
Step 5 Summary & Emotional Sublimation
1. Knowledge Map: Draw a mind map on the board summarizing: Health Problems -> Structures -> Advice (should/shouldn’t).
2. Value Sharing: Discuss: "Why is it important to listen to good advice about health " Emphasize the importance of self-care and caring for others.
3. Chant: Recite together: "Should, should, what should I do Should rest, should drink, should eat well too! Shouldn’t stress, shouldn’t stay up late, Healthy habits help us great!"
作业布置 必做：Complete the exercises in the Workbook related to should/shouldn’t.
选做：Design a "Healthy Life Poster" featuring 3 common health problems and 3 pieces of advice using the target language.
