Dear editor，
I'm writing to tell you something about the problem of food safety.
A couple of days ago，one of my classmates bought a bag of food from a supermarket. Some roommates were invited to enjoy the food. Unfortunately，after finishing it，all of them got poisoned and had stomachaches with their faces pale. They were quickly sent to a nearby hospital. A doctor examined them and gave them some medicine. They were out of danger soon after taking the medicine.
This accident made me realize the seriousness of the food safety problem. I sincerely hope that the whole society pay much more attention to food safety.
Yours，
Li Hua
