Step 1 Lead in Ask and answer： -What are we doing？ -We are having our English class. Create a situation: Let’s open the memory book of 2020 and recall. There was a pandemic outbreak at that time. When you heard the news, what were you doing What were people in the picture doing Let students look at the pictures and make sentences. Step 2 Presentation(Identify the tense) Observe the four sentences and find out the sentence structure of past progressive tense. Then conclude the meaning of it. We/You/They + were V-ing I/He/She/It + was V-ing Review the rules of changing verbs from their base forms into the “ing”forms. Then, ask students to put these verbs: play, take, have, run, shop, sleep, swim, write in three different plete the sentences in Grammar Focus. Step 3 Understand the tense When the pandemic happened, what were your parents doing First, look at the pictures and make sentences. Then, let students use a “magic word—when” to combine two related sentences. After that, let students find out the sentence structure of past progressive tense with when-clause. A was/were V-ing when B V-ed. When A V-ed, B was/were V-ing. When the pandemic happened, we were staying at home. What were other people doing First, look at the pictures and make sentences. Then, let students use a “magic word—while” to combine two related sentences. After that, let students find out the sentence structure of past progressive tense with while-clause. A was/were V-ing while B was/were V-ing. While A was/were V-ing, B was/were V-ing. Put the when-clause and while-clause together and let students think when we use “when” and when we use “while” List two questions to help them: 1. when和while引导的从句中动词有什么特点和区别？ 2. when和while引导的从句中常见的时态有什么区别？ Then the teacher conclude the rules with students together. Step 4 Practice the tense Work on 4a. Look at the table and write sentences with both while and when.Let students find out the long action and short action first. Fill in the blanks with was, were, when or while. After checking the answer let students read the passage and answer three questions： What caused the accident What was the car like after hitting a tree What do you want to say to the driver Step 5 Have a self check.
