Step Four: Discussion (7’)
(T: We have learned when the accident happened, what Chen Wei and Susan did to help the injured girl. Now, please look through the instruction quickly. Then discuss in pairs and give me some advice on how to deal with an injured person in an accident?)
Let the students discuss in pairs for a moment. Then the teacher asks them to give the results of their discussion and shows some dos and don’ts on the screen, which will help them to get their discussion through.
But if you come across such an accident, what will you do?
Dos Don’ts
Leave the person where he/she is carry the person
Telephone for help move the person
Stay with the person let the person get up
Tell the person not to worry
Tell the person to stay still
(T: To let you know how to begin, I’ll demonstrate a dialogue with one of you. Any volunteer?)
The dialogue:
T: What should I do if someone falls off a bicycle and hurts himself/herself badly?
S: You must stay with him/her and check whether he/she can breathe.
T: If not, what should I do then?
S: You ought to call the first aid center as soon as possible .Do remember the number 120.
After that, get the students to make their own dialogues for a while. At last the teacher asks one or two pairs to show their conversations.

Step Five: Consolidation (on the slide) (3’)
Fill in the blanks, by using the proper forms of the words or expressions:

One day, Chen Wei and Susan were walking down the street when they saw an accident. A child ran into the street and knocked a girl off her bicycle. They went up to help. The girl could not move but breathe. Chen Wei wanted to carry her to the side of the road. But Susan thought they’d better leave her where she was, because if someone was badly hurt, you mustn’t move them. They called the first aid center for help. A few moments later, the girl came to herself and told them her knee, her foot and her head hurt. Chen Wei asked her to take it easy. When the girl wanted to get up, they said she should stay still. But the girl said she ought to go back home and cook for her grandmother.
