I have a good friend names Liu Mei. She is our monitor and one of the excellent student in our class. Clever as she is, but she works very hard. We have a lot in common or have a lot to talk about. She was doing her homework one Sunday morning while she smelt something burning. She stopped look out of the window and find a cloud of smoke coming out of her neighbor’s house. She called 119 immediately. Ten minutes late, the firemen came and put out the fire. His neighbor was very thankful with her help.
