Understanding the dialogue content and key safety rules introduced. Teaching Difficult Points Understanding the definition and components of PPE (personal protective equipment). Extracting detailed safety information from the dialogue. 【Teaching Aids】 Multimedia courseware, dialogue audio, expression cards, PPE pictures Learning Objectives 【Knowledge & Skills】 Students can master key expressions: make sure, helmet, protect… from, hazard, toolbox, lead to, accident. Students can understand the main content of the dialogue between David (new construction worker) and Paul (supervisor) about site safety rules. 【Ability Objectives】 Students can listen to the dialogue and check prelistening predictions. Students can extract key safety rules (PPE use, tool check) from the dialogue. 【Affect, Attitude & Values】 Students can understand the importance of personal protective equipment (PPE) in construction work and develop a sense of responsibility for safety. Procedure Design 步 骤 活 动 设 计 设计意图 Step 1 Lead-in & Prediction (5 mins) Activity: Review safety signs from Period 1 with a quick quiz. Ask students to read the expressions and guess what the dialogue is about (e.g., "safety rules for new construction workers"). Introduce the dialogue background: David is a new construction worker, and Paul is his supervisor. To review old knowledge, train prediction ability and prepare for listening. Step 2 Key Vocabulary Learning (10 mins) Activity 1: Present expressions with explanations and examples: make sure: to ensure something happens; e.g., "Make sure you work safely." helmet: hard hat for head protection; e.g., "Wear a helmet on the construction site." protect… from: keep safe from harm; e.g., "PPE protects you from hazards." PPE (personal protective equipment): safety gear like boots, vest, gloves. hazard: danger; e.g., "Construction sites have many hazards." lead to: cause; e.g., "A small mistake can lead to a serious accident." Students practice reading in pairs and correct pronunciation (e.g., "hazard" /ˈhæzəd/, "accident" /ˈæksɪdənt/). To master vocabulary, reduce listening difficulty and provide language support for speaking. Step 3 Listening & Comprehension (15 mins) Activity 1: Play the dialogue audio once. Students check their predictions. Activity 2: Play again. Students answer key questions: 1. What does Paul remind David to do first before entering the site? 2. What does PPE include? 3. What should David check about the tools before use? Activity 3: Explain key sentences and the note about PPE. Students read the dialogue aloud to practice intonation. To develop listening skills, extract detailed information and understand construction site safety rules. Step 4 Summary & Homework (5 mins) Summary: Review key expressions and the main safety rules from the dialogue. Homework: 1. Copy the key expressions and make 1 sentence for each. 2. Listen to the dialogue 3 times and retell the safety rules David learned. To consolidate dialogue content and improve listening and retelling ability. 学科网（北京）股份有限公司 $
