Unit 7 Know Our World Lesson 38教学设计 -2024-2025学年冀教版（2012）英语八年级下册

Unit 7 Know Our World Lesson 38: The World Is a Big Place I. Teaching Objectives By the end of the lesson, students will be able to: Extract key details about the world’s geography and population to match paragraphs with main ideas, aligning with High school entrance examination reading comprehension skills. Master vocabulary related to the earth’s features and population (e.g., increase, dry, surface, billion, total) and use them correctly in context, preparing for High school entrance examination vocabulary tasks. Understand the distribution of continents and oceans, and challenges like population growth and unlivable areas, supporting High school entrance examination - style analysis of global issues. Collaborate in groups to match continents with their descriptions, enhancing High school entrance examination teamwork and geographical knowledge application. II. Key Points & Difficulties Key Points Global Issues and Geography: Population growth: From 7 billion (2010) to projected 9 billion (2050). Livable land: Only 1/3 of the earth is land, with deserts, mountains, and ice limiting where people can live. Continents and oceans: 7 continents (6 livable except Antarctica) and oceans covering 2/3 of the earth’s surface. Vocabulary: increase, dry, surface, billion, total – used to discuss the earth’s population and geography. Difficulties Explaining complex global issues (e.g., population growth’s impact on resources) clearly in English. Accurately using geography - related vocabulary (e.g., “surface” to describe the earth’s coverage) in sentences. Correctly matching continents with their diverse descriptions (size, countries, features). III. Teaching Methods Task - Based Learning (TBL): Through paragraph - main - idea matching, vocabulary filling, continent - description matching, and global - issue discussions. Map - Based Visualization: Using world maps to locate continents and oceans, linking to text details. Collaborative Learning: Group work for continent - description matching, emphasizing peer feedback on accuracy. IV. Teaching Aids CAI (world map animations, vocabulary definitions, continent - fact cards). Textbook, worksheets, and “Global Issue Cards” (with terms like population, livable land). V. Teaching Procedures Step 1: Warm - up – Our Planet’s Basics (5 mins) Discuss the THINK ABOUT IT questions: How many continents are there? What are they? (E.g., “Seven: Asia, Africa, Europe, North America, South America, Australia, Antarctica.”) What do you know about your living place? (E.g., “I live in [city], part of [continent/country], with [local geography like rivers or hills].”) Share: Invite 3–4 students to share. Write keywords: continents, home, geography, earth. Step 2: Pre - reading – Vocabulary and Map Prep (8 mins) Vocabulary Introduction: Teach words with examples: increase: “The world’s population is increasing.” dry: “Deserts are dry and hard to live in.” surface: “Oceans cover most of the earth’s surface.” billion: “Over 7 billion people live on earth.” total: “The total number of continents is seven.” Map Activity: Show a world map, label continents and oceans as in the text. Step 3: Reading – Extracting Global Details (12 mins) Complete Let’s Do It! 1 (Paragraph - Main - Idea Matching): Answers: Paragraph 1: c (population problem) Paragraph 2: e (unlivable areas) Paragraph 3: a (six livable continents) Paragraph 4: d (ocean coverage) Paragraph 5: b (protect the earth) Text Analysis: Discuss how each paragraph introduces a key topic (population → livable land → continents → oceans → earth protection). Global Issue Discussion: Ask: “Why is population growth a challenge? How does limited livable land make it harder?” (Link to text: “Only 1/3 of earth is land, and some is unlivable.”) Step 4: Vocabulary and Grammar Practice (10 mins) Complete Let’s Do It! 2 (Blank - Filling): Answers: increasing total dry surface billion Sentence Expansion: Example: “To protect the earth, we must slow population increase, save dry lands, and care for the surface—for a total of 7 billion+ people.” Error Correction: Fix mistakes like “The surface of earth” → “The surface of the earth” (article use). Step 5: Group Project – Continent - Description Matching (15 mins) Task Introduction: Match 7 continents (Asia, Africa, etc.) with descriptions (size, countries, features) using text details. Example: “Asia is the biggest continent—has the Himalayas.” Group Work: Students discuss and match, using maps/text for reference. Teacher guides fact - checking (e.g., “Africa has elephants—correct.”). Class Sharing: Groups present matches. Feedback focuses on accuracy (e.g., “Asia is the biggest—text confirms.”) Step 6: Summary and Homework (5 mins) Summary: Recap global issues (population, livable land), continents, oceans, and the need to protect the earth. Homework: （1）Write a 6 - sentence reflection: “Why Protecting the Earth Matters” (use 3 terms: population, continents, surface). （2）Research one more geography fact (e.g., “The Pacific Ocean is the largest”) and share in class.

Blackboard Design Global Issues and Geography: Topic Key Details Population 7 billion (2010) → 9 billion (2050 projection) Livable Land 1/3 of earth; deserts/mountains limit living Continents 7 total; 6 livable (except Antarctica) Oceans Cover 2/3 of surface; 5 named parts Key Vocabulary: increase, dry, surface, billion, total Core Message: “Earth’s geography shapes our future—protect it for generations!” 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
