It was a cold winter day.Three students were reading books in the library.When they left the reading room ,one of them threw away the magazine and it fell into the hall.The heater was on and it was hot.Soon the magazine started to smoke.Then it started to burn.The flames grew quickly.
Outside a passer-by saw the horrible scense and called 119.In a few minutes ,came several fire-engines and firemen jumped out to put out the fire.
Worse still ,a little girl was trapped on the fifth floor of the library .Dangerous as it was,a brave fireman climbed the ladder ,broken the fifth floor's window and saved the girl.Luckily ,both of them didn't get hurt.
Finally,with the help of the fire hose attached to hydrant ,the terrible fire was put off.However,the library was badly damaged.Nowhere was in good condition.
The student was sad for what he did.
