课 题 Unit 4 The wonders of nature Section A 1a-1d 年 级 八 课 时 第一课时
备课 教学目标 1. 语言能力：能听懂关于“世界自然奇观”的描述性对话；掌握核心词汇（wonder, measure, deep, high, square kilometre, below sea level）及句型（What’s the... It’s... metres high/deep. Its surface is... metres below sea level.）；能用英语描述地理特征和测量数据。2. 思维品质：通过匹配图片与名称、填写数据表格，培养观察力与信息整合能力；在讨论中比较不同地貌特征，提升逻辑表达与空间认知能力。3. 文化意识：了解全球著名自然景观及其地理意义，增强对地球多样性的敬畏之心；树立环保意识，认识到保护自然奇观的重要性。4. 学习能力：运用听力预测策略（看图表/关键词）捕捉关键信息；通过笔记记录具体数值和形容词最高级；在小组合作中学会提问与回应。
教学重难点分析 重点：1. 掌握描述自然地貌的核心词汇与短语（e.g., the highest mountain, the deepest trench, below sea level）。2. 听懂并准确填写听力中的地理数据（高度、面积、深度等）。3. 熟练运用“What’s the... ” “It’s...” “Its surface is...”等句型进行问答交流。难点：1. 区分“high”（海拔高）与“deep”（海洋深）、“below sea level”（海平面以下）等概念的实际应用。2. 理解大数字（如8,848.86 / 9,000,000）的英文读法与书写规范。3. 在口语活动中流畅组织语言描述多个地理特征，避免混淆数据。
教学环节
Step 1 Warm-up & Lead-in (Picture Talk)1. Show & Guess: Display the six pictures from 1a without labels. Ask: “What do you see Where might these places be ” Elicit names like mountain, desert, river, waterfall.2. Vocabulary Preview: Introduce key words: wonder, measure, deep, high, square kilometre, below sea level. Use real-life examples: “Mount Qomolangma is 8,848.86 metres high.” “The Dead Sea is 416 metres below sea level.”3. Lead-in Question: “Which of these places have you heard of Which one surprises you most ” Step 2 Pre-listening Matching (1a)1. Match Places to Pictures: Students work individually or in pairs to match the place names (Nile River, Angel Falls, Mount Qomolangma, Dead Sea, Sahara Desert, Mariana Trench) with pictures A–F.2. Check Answers Together: Project correct matches. Briefly introduce each location:- Angel Falls: Highest waterfall- Mariana Trench: Deepest ocean trench- Sahara Desert: Largest hot desert- Dead Sea: Lowest point on land- Mount Qomolangma: Highest peak- Nile River: Longest river (traditionally)3. Pronunciation Drill: Practice saying the names aloud, especially Qomolangma, Mariana, Sahara. Step 3 While-listening (1b & 1c: Listening for Details)1. First Listen (1b): Play the game show audio. Students complete the “Description” column using superlatives:- Mount Qomolangma → the highest- Sahara Desert → the largest- Dead Sea → the lowest- Mariana Trench → the deepest2. Second Listen (1c): Play again. Students fill in the “Measurement” column with numbers from the box:- 8,848.86 → Mount Qomolangma- 9,000,000 → Sahara Desert- 416 → Dead Sea- 11,000 → Mariana Trench3. Focus on Language: Highlight sentence patterns:- “It’s ___ metres high.”- “Its surface is ___ metres below sea level.”- “About ___ square kilometres in size.” Step 4 Post-listening Speaking (1d: Pair Work & Discussion)1. Model Dialogue: Teacher demonstrates with a student: A: What’s the lowest place on earth B: It’s the Dead Sea. A: How low is it B: Its surface is 416 metres below sea level. A: Now, what’s the deepest place in the ocean 2. Pair Practice: Students take turns asking and answering about all four places using 1d structure. Encourage them to add extra info: “I think it’s amazing because...”3. Group Challenge: Each group picks one wonder and creates a 30-second “travel ad” introducing it to classmates using target language. Step 5 Summary & Emotional Sublimation1. Quick Review: Call out descriptions — students shout the place name (e.g., “the highest mountain!” → “Mount Qomolangma!”).2. Value Sharing: “These wonders are gifts from nature. We should protect them, not destroy them.” Show short video clip or image of environmental damage vs. conservation.3. Reflection Prompt: “If you could visit one of these places, which would you choose Why ” Write 1–2 sentences as exit ticket.
作业布置 必做：Write 5 sentences describing two different wonders using the structure: “The [place] is the [superlative] in/on the [location]. It is ___ metres [high/deep/low].”选做：Research one more natural wonder (e.g., Grand Canyon, Great Barrier Reef) and prepare a 3-sentence introduction to share next class. Include its measurement and why it’s amazing.
