Picture 3 When we see a house on fire and someone is burnt，we should call 119 first and tell them the exact address on the phone.And we should also call 120 to ask for an ambulance to help.If the person is badly burnt, or if a child has been burnt，we should do nothing but wait for the doctor.If the person is not badly burnt, we can cool the area of skin under the cold tap for several minutes and then put a piece of dry clean cloth over the area of burn. To prevent this, we should not play with fire, be careful with gas and make sure that all the electric wires are safe. Picture 4 If someone is bleeding badly, we must try to stop the bleeding first. If a person loses one third of his/her blood, he/she may die. We can press a handkerchief onto the bleeding point and hold it there. If possible, hold up the part of body which is bleeding. We must be very careful what ever we do. Picture 5 If a person is cut, we can wash the area of the cut, dry it and cover it with a piece of dry clean cloth.

(Students read the words after their teacher twice and then they have a few minutes to read by themselves. At last, the teacher may ask some students to read the words to see if they can read them correctly. ) T: I think you all can read them very well. Now, please look at the screen.
