I did not felt so comfortable today, originally, I did not want to go school, but I changed idea. When listened lecture by a firefighter, I rejoiced, it is a best thing I did to take today’s class.  

This lecture gave me deep impressive. The firefighter show us many cases of fire, and experiment of real fire, let us know just three minutes, a small fire become too  severe fire. Not as same as scene of movie, and also I know, in the house where we should set alarm of fire, the right way is ceiling, every floor should has an alarm, including basement. Every year we should check battery of alarm, if alarm’s color becomes yellow, it is means too old, you would change a new one. This class is so important for every classmate.

When I back home, I checked all the rooms of my house, I am not sure the battery is worked or not, and I found  all alarms old, this weekend I will go to shop to buy new alarms for my house.
