I take a bus to school every day.SO i thought today must be an usually day in the morning.But it go against with my mind.It happened that an old man got help by us, so that he is still alive.Is that amzing?Of course.The old man got heart disease,and everyone in the world can't know when he will be dying.He felt fine5 minutes before,but after he got down.People on the bus are afraid.A young man who is a doctor stand out.He told us how to do untill 120 arrive.He took many measures to help the old man.What can i do?I call the 120,i think it is the most important.The old man got fine in the evening.I just got the new,i'm so happy that i can make a peesong alive
