Section A (4a-4d) 课时 课型 第 3 课时 语法课 主题情境 人与自然 教学材料分析Teaching Material Analysis The focus of this lesson is the Past Continuous Tense, specifically how it functions in complex sentences using the conjunctions "when" and "while". The exercises (4a–4c) move from mechanical identification to contextual application, culminating in a communicative interview task (4d). Students must grasp how this tense sets the background for specific past events or describes simultaneous ongoing actions. 教学目标Teaching Aims Language Competence: Accurate use of was/were + V-ing and the logic of when vs. while. Thinking Quality: Categorize and contrast temporal relationships between overlapping past actions. Learning Capability: Summarize grammar rules through inductive observation of textbook examples. Cultural Awareness: Reflect on human resilience and mutual support during natural disasters (e.g., the tornado story in 4c). 教学重点 Key Points The sentence patterns: Past Continuous + when + Simple Past vs. Past Continuous + while + Past Continuous. 教学难点 Difficult Points Choosing the correct conjunction based on whether the verb is a "stativity/duration" verb or a "point/instant" verb. 教学方法 Teaching Methods PPP Mode, task-based and communicative approaches 教学工具 Teaching Aids Multimedia projector, blackboard, handouts, recording device 教学过程 Teaching Procedures Step 1 Lead-in (4 mins) Briefly recall the typhoon story from the previous lesson. Ask: "What were the people doing when the disaster hit?" Step 2 Presentation (Grammar Focus) (10 mins) Observation: Display sentences from 4a. Ask students to circle the time conjunctions and underline the verbs. Induction: Guide students to find the pattern: When is usually followed by a short, finished action (Simple Past). While is usually followed by a long, ongoing action (Past Continuous). Step 3 Practice (4a–4c) (18 mins) Mechanical Drill (4b): Students combine sentences. Teacher's Tip: Walk around to ensure they are changing the correct verb into the -ing form (the longer action). Contextualized Drill (4c): Students complete the cloze passage about Jenny’s family. Deep Dive: Discuss the emotional shift in the story—from fear to relief—and how the tense helps "paint" the scene. Check & Correct: Peer-check answers. Clarify why "were starting" is used in the final paragraph of 4c to show a gradual process. Step 4 Production (4d) (10 mins) Students work in pairs. Student A acts as a reporter; Student B is a survivor. Requirements: Must use at least three sentences containing when or while. Performance: Invite 2-3 pairs to present. Focus on natural flow rather than just grammatical accuracy. Step 5 Summary (3 mins) Recap the "Time Line" of actions. Self-assessment: "Can I explain what my family was doing at 8:00 PM last night using when/while?" 作业设计 Homework Design Basic Task: Complete three original sentences describing what three different family members were doing when you got home yesterday. Extended Task: Write a short news report (60-80 words) about a local rainstorm or event, using the Past Continuous to describe the scene when the event reached its peak. 板书设计 Blackboard Design 教学反思 Teaching Reflection The inductive approach (4a) worked well to let students "discover" the rule rather than being told. However, some students still confuse "while" with "when" when both actions are continuous. I need to emphasize that "while" stresses the duration. The story in 4c provided a good emotional anchor, making the grammar feel less "dry." 教学评价Teaching Evaluation Accuracy: 90% of students correctly identified the verb forms in 4b. Engagement: The 4d interview showed high engagement, though some students needed more scaffolding for the "Reporter" questions. I will provide a "Question Bank" next time. 学科网（北京）股份有限公司 $
