Key and Challenging Points Key Points: Differentiate simple past (past events) vs. present perfect (past - present connection, results, frequency). Challenging Points: Choosing the right tense for context; using time expressions correctly. III. Teaching Procedures (Total Duration: 45 Minutes) Step 1 Introduction to Tense Differences (10 Minutes) Show examples (e.g., “Daniel went to Beijing (simple past)” vs. “Daniel has lived in Beijing (present perfect)”) and ask: “What’s the difference in meaning and usage?” Introduce the topic: “Today, we’ll learn to use simple past and present perfect—key for talking about online tour experiences!” Step 2 Tense Explanation & Practice (12 Minutes) Rule Presentation: Explain simple past (past actions, no present link) and present perfect (past - present link: continues, result, frequency). Use online tour scenarios (e.g., “visited a virtual museum (simple past)” vs. “have visited many virtual museums (present perfect—frequency)”). Clarify time expressions: simple past (yesterday, last week) vs. present perfect (ever, never, since, for). Practice—Activity A: Students complete sentences (Activity A) with correct tenses. Walk around to clarify usage (e.g., “visited (simple past)” vs. “have tried (present perfect)”). Step 3 Application in Conversations (10 Minutes) Task—Activity B: Students finish Mr Wu’s sentence practice (Activity B), applying tense rules. Discuss answers, emphasizing tense - time expression matches (e.g., “have finished (present perfect—just)” vs. “finished (simple past—20 minutes ago)”). Step 4 Speaking Practice (8 Minutes) Task—Activity C: Students complete Millie & Simon’s conversation (Activity C) with present perfect and simple past. Highlight how tenses show experience (present perfect) and past events (simple past). Step 5 Summary & Homework (5 Minutes) Summary (3 Minutes): Recap simple past (past events) vs. present perfect (past - present links: continues, result, frequency), and time expressions. Homework (2 Minutes): Writing: Write 3 sentences about your online activities (e.g., virtual tours) using simple past and present perfect. Reflection: List one online experience and describe it with both tenses. IV. Assessment of Teaching Effectiveness Check Activity A/B answers for accurate tense use. Evaluate Activity C conversation for correct tense - context matching. V. Design Purpose Introduction: Use online tour examples to clarify tense differences. Explanation/Practice: Break down rules and apply in structured tasks. Application: Reinforce in conversations and writing, linking to digital travel stories. VI. Blackboard Design Unit 3 Grammar—Simple Past vs. Present Perfect Key Differences: - Simple Past: Past events (no present link) → *visited, saw* - Present Perfect: Past - present link (continues, result, frequency) → *have visited, have seen* Time Expressions: - Simple Past: yesterday, last week - Present Perfect: ever, never, since, for Homework: Write online activity sentences! VII. Teaching Reflection Strengths: Clear tense breakdown and online - themed practice. Weaknesses: Some students may struggle to choose tenses for complex contexts. Improvements: Add a “tense sorting” game: Sort online tour sentences into simple past vs. present perfect. This reinforces structure recognition. 学科网（北京）股份有限公司 $$
