Teaching procedures and ways 教学过程与方式Step I Review of present progressive tenseShow three pictures on the screen (some soldiers running, a man playing tennis, a man eating bread). Ask about the pictures one by one, and help students review the present progressive tense. T: What are they doing? Ss: They are running T: What is he doing? Ss: He is playing tennis. T: What is the man doing? Ss: He is eating bread. Lead the students into real situations.T: What are you doing now? S: I am listening to you. T: Yes, he is listening to me. Repeat this with one girl student. Practice with the whole class, trying to review the progressive tense with different personal pronouns. Then let students ask and answer in pairs, using the present progressive tense. Step II Introduction of past progressive tenseIntroduce the past progressive tense to students.Ask one student (student A) to leave the classroom and wait outside the door. Then ask two students to do actions, one (students B) is writing on the blackboard and the other (student C) is walking around the room. They keep doing it until the teacher asks them to stop. T: What are you doing? (Ask student B)SB: I am writing on the blackboard. Write the sentence on the blackboard. Repeat this with student C, and write “I am walking in the room.” on the blackboard.Ask the student outside to come in and sit down. Then ask the two students who are doing actions to sit down too. Ask the student B who was writing on the blackboard.T: What were you doing when student A came in? SB: I was writing on the blackboard when he came in. Write “I was writing on the blackboard” on the blackboard.T: He was writing on the blackboard when student A came in.Ask the class to repeat it: He was writing on the blackboard when student A came in.Repeat this with the student C who was walking in the room. Write “I was walking in the room.” on the blackboard.Ask some other students the question: What were you doing when student A came in? Then let students ask and answer the question in pairs.Point to the blackboard. Help students to find out the differences between the two pairs of sentences. 1. I am writing on the blackboard. I was writing on the blackboard.2. I am walking in the room. I was walking in the room. Point to the pair of sentences on the right side and tell students:T: This is a new tense the past progressive tense. The basic structure is:subject + was/were + v-ing + (adverbial of time)1）概念：表示过去某时正在进行的状态或动作。2）过去进行时的主要用法是描述一件事发生的背景；一个长动作发生的时候，另一个短动作发生。3）常用的时间状语this morning, the whole morning, all day yesterday, from nine to ten last evening, 以及when, while引导的时间状语从句It was raining all day yesterday.My brother fell while he was riding his bicycle and hurt himself.It was raining when they left the station. When I got to the top of the mountain, the sun was shining.Step III Listening (Section A: 2a, 2b)Let students do some listening practice with the use of when and while. This will help them better understand the difference between them. T: Turn to page 19, look at 2a. Here are five sentences. Go through the sentences first. Then listen to the tape and you will hear a recording of a reporter talking to several people. Please put number 1 in front of the thing that happened first, number 2 in front of the thing that happened next and so forth.Play the recording the first time, students only listen and get a general idea of it.Play the recording a second time. This time ask students to write the numbers in front of the sentences.Then check the answers. Then let students go through the sentences in 2b. Play the recording again and let them complete the sentences with “when” or “while”.T: What are the differences between “when” and “while”?Step IV Adverbial clause with when/while Explain the different use of “when” and “while”.T: The word “when” comes before a quick action that happens only once. The word “while” comes before an action that continues for some time. For example:When I got home, he was having supper.While I was sleeping, my father came in.So here “got home” and “came in” are quick actions that happen only once. “sleeping” and “having supper” are actions that continue for some time. Now tell which actions in 2b are quick actions and which actions can continue for some time. Quick actions: land, get out, call the police, call the TV stationActions that can continue: walk down, go shopping, buy, visit the museumLet students do some substitution drills to practice the use of “when” and “while”. Step V Oral practice (Section A: 2c)This activity provides guided oral practice using adverbial clauses with “when” and “while”.T: We learned yesterday that the UFO landed on the small town. Do you remember? Later, it took off and left. Look at the picture in 2c. How many persons can you see? Ss: Five.T: What was each person doing when the UFO took off? What was the girl doing? Language points:take off: 起飞if an aircraft takes off, it rises into the air from the ground; opposite, lande.g. I felt quite excited as the plane took off from the airport. land: 着陆if a plane, bird, or insect lands, it moves safely down onto the grounde.g. Flight 846 landed five minutes ago.The bird landed gracefully（优雅地）on the water.S: She was eating ice-cream when the UFO took off.T: Yes. We can also say “While the girl was eating ice-cream, the UFO took off.” What was the man in the middle of the picture doing?S: He was taking a photo when the UFO took off.T: Another way of saying of this sentence is .?S: While the man was taking a photo, the UFO took off.T: Good! Now, work in groups of three and make conversations like this about other people in the picture. Pay attention to the use of “when” and “while”.Move around the classroom, checking the progress of the groups and offering help as needed. Then ask a group to present their conversation to the class.Sample conversations:1. A: What was the girl doing when the UFO took off?B: While the girl was eating ice cream, the UFO took off.C: The girl was eating ice cream when the UFO took off.2. A: What was the man doing when the UFO took off?B: When the UFO took off, the man was taking a photo.C: While the man was taking a photo, the UFO took off.3.
