3. The teacher then asks the students whether they have met any accidents, if one of the accidents happens, what they should do.
(Probable answers: If someone is hit by a car, leave him/her where he/she is and call 120. If someone gets burned by boiling water/oil, wash the burns under the cold running water and see a doctor. If a person is bitten by a dog/cat, wash the bites under the tap and go to hospital in 24 hours. If a person is bleeding badly, hold up the part higher than the heart and see a doctor. If someone has stopped breathing, use the mouth-to-mouth way. If there is anything you can’t deal with, go to hospital and see a doctor.)(Write down the new words in the speech on the blackboard: bite, bitten, bleed, hold up, breathe, mouth-to-mouth.)
T: You have told me a lot about how to deal with an accident, which can be called FIRST AID (written down on the blackboard). And who can tell me the number of first aid center?
S: The telephone number of the first aid center is 120.
(In this step, the teacher should encourage the students to express themselves in English. If there are some difficulties, they can ask the teacher for necessary help. And the students can learn some practical experience in their life.)

Step Three: Dialogue (20’)
1. The teacher tells the students: Today we are going to learn some first aid. It will be of great help in our daily life. Look at the screen and get through the questions first, then watch the videotape and I will ask some of you to answer the questions.
2. Show some questions about the dialogue on the screen, and play the videotape of the dialogue, let students look and listen.
Qs: What happened to the girl while she was riding a bicycle?
What was wrong with her?
What did Chen Wei want to do to her?
Why did Susan ask Chen Wei leave the girl where she was?
What did Chen Wei do then?
How did the girl feel after she came to herself?
What did she want to do?
Was she allowed to do so?
3. Get the students to work in pairs for a while and then ask some of them to answer the questions.
4. Play the videotape again, and get the students to read after the tape in a low voice.
5. Let the students practice reading aloud and act the dialogue in groups.
6. Ask one or two groups to act before the whole class. The teacher assesses their performances.
7. Deal with some language points which are all made on the slide. Explain the new expressions by letting the students make sentences.
