教学目标Teaching Aims
1. Language Competence:
Synthesize information using specific data (large numbers), comparatives, and superlatives to describe geographical features and ecological facts.
2. Learning Ability:
Master the "Skim-Scan-Map" strategy to organize complex texts and use the "Amazon Example" as a template for creative writing.
3. Thinking Quality:
Critically analyze the "Desertification" phenomenon, moving from factual understanding to proposing solutions for climate change.
4. Cultural Awareness:
Develop a global perspective by comparing the "Lungs of the Earth" (Amazon) with the "Great Desert" (Sahara), fostering a sense of "One Earth."
教学重点
Key Points
Transforming raw data from the reading into a structured, visual poster format.
教学难点
Difficult Points
Using the "Reflecting" section to conduct deep self-evaluation and connecting the "growing desert" to human responsibility.

教学过程 Teaching Procedures
I. Pre-reading (Engagement & Activation) (5 mins)
Flash-Review: Rapid-fire Q&A about the Amazon Rainforest (based on 4b).
Prompt: "How big is it?" "What is its nickname?" (5.5 million sq km; The lungs of the Earth).
Visual Prediction: Show the image of the Fennec Fox.
Question: "How does it survive in 180°C heat (sand surface) or lack of water?" Lead to the keyword: Adaptation.
II. While-reading (In-depth Analysis) (8 mins)
Task 1: The "Fact-File" (Scanning): Students scan The Sahara Desert to find specific data for the Mind Map (Activity 1).
Check-point: Focus on the "Size" (9 million sq km) vs. the Amazon (5.5 million sq km).
Task 2: Comparative Analysis: Identify three "Superlatives" in the text.
e.g., "one of the oldest places," "the largest hot desert," "the world's largest."
Task 3: Critical Thinking (The 'Why' of Growth): Read the final paragraph.
Discussion: "The Sahara is getting drier and drier. Why?" (Climate change, less rain). "What are the effective measures?" (Planting trees, reducing CO2).
III. Post-reading (The "Nature Wonder" Project) (12 mins)
Activity 1: Silent Reading for Gist
Students read the "Laughter is the best medicine" text individually.
Task: What is the main message of the text? (e.g., Laughter has physical and mental health benefits; it's a powerful tool for coping.)
Activity 2: Detailed Reading & Task
Students read the text again.
Task: Complete a simple T-chart or answer guided questions:
What are 2-3 benefits of laughter mentioned in the text?
How can laughter help us "grow up" or deal with emotions?
Activity 3: Sharing & Discussion
Students share their findings in small groups.
Teacher leads a brief class discussion, linking the text's ideas back to the unit's big question: "How do we deal with our emotions?"
IV. Post-reading & Project Work (15 mins)
Step 1: Group Research (4a/4b): Groups choose a wonder (e.g., Mount Qomolangma or The Great Barrier Reef).
Scaffolding: Provide a "Fact Card" template: Name -> Size/Age -> Plants/Animals -> Special Facts.
Step 2: Poster Creation: Apply the "Sahara" and "Amazon" styles. Students must include a "Warning/Call to Action" (e.g., Protect the reef!).
Step 3: Gallery Walk & Report (4c): One "curator" stays at the poster to present; others rotate and take notes.
Requirement: Use at least one sentence like: "It is [Number] times larger than...".
V. Summary, Presentation (5 mins)
Self-Audit: Go through the 5 questions in the "Reflecting" box.
Closing Quote: "Nature makes us wonder. That is why it is wonderful." (Briefly discuss the double meaning of 'wonder'—to be curious and to be amazed).

Refine: Polish the group poster and upload a digital version to the class platform.
Extended Reading: Find one more fact about the Fennec Fox or Amazon animals and write 3 sentences using comparatives.

教学反思
Teaching Reflection
The lesson successfully bridges the gap between reading for information and writing for a purpose. By comparing the Sahara and the Amazon, students practiced the target grammar in a meaningful context. The "Mind Map" was an effective scaffold for the weaker students, while the "Project" allowed stronger students to shine. However, time management during the "Gallery Walk" needs to be tighter to ensure all groups present.
教学评价Teaching Evaluation
Task Performance: 90% of students completed the mind map accurately.
Oral Fluency: Most groups used large numbers correctly during reports, though some struggled with "million" vs. "billion."
Emotional Goal: Students expressed genuine concern for the Sahara's growth, indicating the values-based objective was met.
