教学设计 课题 Unit 5 What were you doing when the rainstorm came-Section A-Grammar Focus-4c 课时 1 教学目标 1.Language ability: Apply past continuous tense to describe simultaneous or interrupted actions, and use "when/while" to connect clauses correctly. 2. Cultural awareness: Recognize how people communicate about emergencies in English-speaking contexts, enhancing cross-cultural understanding. 3. Thinking quality: Analyze sentence structures to distinguish between past simple and past continuous tense in contexts. 4. Learning ability: Develop autonomous learning by practicing tense usage through interactive exercises (e.g., 4c role-plays). 重难点 Grammar: Differentiate between "was/were doing (past continuous)" for ongoing actions and "did (past simple)" for sudden events, e.g., "While he was studying, the light went out." Usage: Master the rule: "when + past simple" often interrupts a "while + past continuous" action. Practice: Apply tenses in 4c group activities to retell past events coherently, avoiding tense mismatches. 教学环节 教学过程 新课教学 T: Good morning, class! Today, we are going to continue our learning of Unit 5 “What were you doing when the rainstorm came?”. In the last class, we learned some new words and expressions, and also talked about some past events. Now, let’s do a quick review. Who can tell me some words we learned related to the rainstorm? Yes, Tom. S1: Rainstorm, wind, light, window... T: Great! And can you use one of these words to make a sentence? S1: The wind was very strong during the rainstorm. T: Excellent! Sit down, please. So, we know that when we talk about past events, especially those that were happening at a certain time in the past, we need to use a special tense. Do you know what it is? S (together): Past continuous tense. T: Exactly! Today, we are going to focus on the Past Continuous Tense and also learn how to use “when” and “while” correctly in sentences. Are you ready? S (together): Yes! Grammar Focus 讲解 T: First, let’s look at the Grammar Focus on the screen. Read these sentences aloud with me. “What were you doing at eight last night? I was taking a shower.” (Lead the students to read all the sentences in Grammar Focus) T: Now, let’s analyze these sentences. What were you doing at eight last night? This sentence is asking about an action that was in progress at a specific time in the past, which is eight last night. And the answer “I was taking a shower” shows that the action of taking a shower was happening at that time. Can you see the structure of the Past Continuous Tense? It is “was/were + V - ing”. “Was” is used for the first person singular “I”, the third person singular “he”, “she”, “it”, and “were” is used for the second person “you” and all plural subjects like “we”, “they”. For example, if I want to say he was reading at that time, I use “he was reading” because “he” is the third person singular. And if I say “we were playing basketball”, I use “were” because “we” is a plural subject. Do you understand? S (together): Yes. T: Good. Now, let’s look at another pair of sentences. “What was she doing at the time of the rainstorm? She was doing her homework.” Here, “at the time of the rainstorm” is also a past time point. We use the Past Continuous Tense to describe what she was in the middle of doing when that rainstorm happened. Who can give me another example like this? Use your own imagination. Yes, Lucy. S2: What was he doing at the time of the football match? He was cheering for his team. T: Wonderful! Your sentence is very good. Now, let’s move on to the sentences with “when” and “while”. Look at “What was he doing when the rainstorm came? He was reading in the library when the rainstorm came.” When we use “when” in this sentence, “when the rainstorm came” is a short action in the past. It happened suddenly, and at that moment, he was in the middle of reading in the library. “When” can be used to introduce a short action in the past, and the main clause usually uses the Past Continuous Tense to show the ongoing action at that time. And look at “What was Jenny doing while Linda was sleeping? While Linda was sleeping, Jenny was helping Mary with her homework.” “While” is used to introduce an ongoing action in the past. Both actions, Linda’s sleeping and Jenny’s helping Mary, were happening at the same time. “While” is always used with an ongoing action, and both clauses can use the Past Continuous Tense. Do you get the difference between “when” and “while” now? S (together): A little bit. T: Don’t worry. We will do more exercises to make it clearer. 4a 练习讲解 T: Now, let’s look at Exercise 4a. Look at the table. We have two people, John and Mary, and some actions. First, let’s analyze these actions. “Take photos”, “play the piano”, “clean his room”, “shop” are all actions that can be in progress, so they can be used in the Past Continuous Tense. And “buy a drink”, “leave the house”, “turn on the radio”, “take the car to the car wash” are usually short actions. Now, let’s make sentences with “while” and “when” according to the table. For example, for the first pair, we can say “While John was taking photos, Mary bought a drink.” Here, John’s action of taking photos was ongoing, and Mary’s action of buying a drink was a short action that happened during that time. We can also say it in another way, “John was taking photos when Mary bought a drink.” Who can try to make sentences for the second pair? Yes, Jack. S3: While John was playing the piano, Mary left the house. John was playing the piano when Mary left the house. T: Perfect! You got it right. Now, everyone, work in pairs. Make sentences for the rest of the pairs in the table. Use both “while” and “when”. (Give the students some time to work in pairs, then ask some pairs to share their sentences) T: OK, let’s stop here. Who wants to share your sentences? Yes, Lily and her partner. S4: While John was cleaning his room, Mary turned on the radio. John was cleaning his room when Mary turned on the radio. S5: While John was shopping, Mary took the car to the car wash. John was shopping when Mary took the car to the car wash. T: Very good! All of you did a great job. Through these sentences, you can see more clearly how to use “while” and “when” with the Past Continuous Tense. 4b 练习讲解 T: Next, let’s move on to Exercise 4b. Here, we need to fill in the blanks with “was”, “were”, “when” or “while”. First, read the passage carefully. At 7:00 a.m., I woke up. This is a past event. Then, think about the actions that followed. For the first blank, we need to choose between “when” and “while”. Since “making my breakfast” is an ongoing action, we should use “while”. And for the subject “I”, we use “was”. So the first part should be “While I was making my breakfast”. And for “my brother”, it should be “my brother was listening to the radio”. Who can fill in the next blank? Yes, Mike. S6: While I was eating, the radio news talked about a car accident near our home. T: Good. You used “while” correctly because “eating” is an ongoing action. And for the next part, “we got to the place of the accident”, this is a short action, so we should use “when”. And the car “was in bad shape from hitting a tree”. The driver “was fine” and the roads “were icy”. Let’s read the whole passage together with the correct words filled in. (Lead the students to read the passage) T: Do you understand why we filled in these words? If you have any questions, feel free to ask. 4c 练习引导 T: Now, let’s come to Exercise 4c. First, look at the chart. In the first column, you need to think about what you were doing at different times last Sunday. For example, at 9:00 a.m., you might write “I was doing my homework” or “I was watching TV”. Then, turn to your partner and ask “What were you doing at 9:00 a.m. last Sunday?”. Your partner will answer, and you write down their answer in the second column. Let’s start. (Give the students enough time to complete the task, walk around the classroom to help and monitor) T: OK, time’s up. Now, let’s share some of your results. Who wants to start? Yes, Peter. S7: At 9:00 a.m. last Sunday, I was playing basketball. And my partner was reading books. At 11:00 a.m., I was having lunch with my family, and my partner was doing housework... T: Great. Thank you for sharing. Now, based on the information in the chart, you are going to write a report. You can start like this: “Last Sunday, while I was sleeping, my partner was doing homework. While I was...” Try to use as many sentences with “while” and “when” as possible. You can write it on your notebook. (Give the students time to write the report, then ask some students to read their reports) T: Let’s listen to some of your reports. Yes, Susan. S8: Last Sunday, while I was having breakfast at 8:00 a.m., my partner was cleaning his room. When I was watching TV at 10:00 a.m., my partner was playing the piano. While I was cooking lunch at 12:00 p.m., my partner was helping his mom in the garden... T: Very good, Susan. Your report is well - written and you used the Past Continuous Tense and “while” and “when” correctly. 课堂总结 T: Today, we learned a lot about the Past Continuous Tense and how to use “when” and “while” in sentences related to past events. Remember, the Past Continuous Tense is used to describe an action that was in progress at a certain time in the past, and “when” is often used with a short action in the past, while “while” is used with ongoing actions. Keep practicing these in your daily English speaking and writing. For homework, I want you to write a short passage about what you and your family were doing during a special event in the past. Use at least 5 sentences with the Past Continuous Tense and “when” or “while”. Class is over. See you next time! S (together): See you! 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $$
