Last Sunday afternoon my friends I were walk-ing in Zhongshan Park when we suddenly heard someone calling for help. A girl fell into the lake she was in danger. One of my friends I jumped into the lake swam towards the girl. When she was pulled out of it,she had stopped breathing. I had learned some knowledge about first aid at school. So I tried to start her breath by using the mouth-to-mouth way. My friend phoned the First Aid Centre. Within ten minutes the girl began to breathe again the doctors from the First Aid Centre arrived. The girl was saved. They all said that what I did was right.
