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.
