Activity1. A game Say: in the reading passage “A City of Heroes”, we learnt some useful words and phrases. Let’s look at the screen and consider their English meanings at the same time. Now we are going to play a game in which you are trying to find as many friends as possible. (Teacher does it with three students first.)The students of Group A each have a piece of paper with some words on it. And students of Group B each have a piece of paper with an English explanation in it. Your friends are those who have the right English explanations for your words. For example, if “rebuild” is one of the words in my paper, then the student who holds “to build again” is my friend. Remember only the right one can become your friend. If you find the most friends , you are going to get a reward from me. Then check the answers together. Activity2.practice Say: now let’s come to the use of the words. Turn to page47, and finish the exercises. , get one student to write down the answers on the blackboard.Then check the answers together. Activity3 lead-in to the word formation Still in the reading passage “ A City of Heroes”, the people of the city are said to be heroes. But why are they heroes? (Because they restored/ rebuilt the damaged cultural relics without destroying its original beauty.) Activity4 Explanation 1. here rebuild= re- + build Question1. What does “re-“mean? (Again) 2. Can you think of any other words beginning with “re-“? (retell, rewrite, recreate) 3. What about respect, recite, repeat, restore? (They don’t belong to this kind. Because they can’t be separated into “re- + word”. For example, we cannot separate recite into re- and cite, because cite is not a word. Activity5.Situational practice Give the students some sentences and get them to change them with other words. 1. He drank the coffee at one mouthful, and filled his pot again.(refilled) 2. After 3 hours’ terrible fight, they controlled the top of the hill again.(recontrolled) 3. With the disappearance of SARS, some theatres and restaurants opened again.(reopened) 4. The students are asked to tell the text again.() 5. I think all of us need to think again about our attitude toward the public health after SARS.(rethink) Conclusion: from this exercise, we come to know another way of forming words. “re-” is a prefix. Have you learnt any other prefixes? (In Unit6, we learnt im-/ir-/in-/un-/non-) and these prefixes have made our vocabulary much larger. 1. Use real objects like a piece of chalk and paper, bread the chalk and tear the paper then ask Q what has happened to the chalk and the book?(pretending to take away the book secretly) (The chalk has been broken and the paper has been torn.) Summarize the structure for the present perfect passive voice: has/have been done 2. Look and ask Show a picture of New Orleans under attack of the hurricane and ask: What has happened to New Orleans? (It has been destroyed by the hurricane.) Show a picture of the bird flu and ask What has happened to the people? (About 30 people have been killed by the bird flu.) Activity7.Sentence formation The students can do two of the six. Write down the answers on the paper. Get 3 students to do them on the blackboard. Finally check the answers together. Activity8. Passages dealing on page47 Activity9. Look and say Describing the changes which have happened to a city in the past years. |
